Description

[001] The present invention relates to an aerosol generating device, a mouthpiece for an aerosol generating device, a set of mouthpieces for an aerosol generating device, a system, a method and a non-transitory computer readable medium comprising a set of instructions.

[002] Aerosol generating devices are provided in which an aerosol generating article containing an aerosol-forming substrate may be inserted. The aerosol-forming substrate is heated by a heating element disposed in or around a heating chamber of the aerosol generating device. The aerosol-forming substrate is vaporized to form an aerosol by heating the aerosol-forming substrate. The generated aerosol may then be drawn toward a mouthpiece for inhalation by a user.

[003] Aerosol generation depends on multiple factors. An important factor is the conditions in which the device is used. In dry or hot conditions, preheating of the substrate may not be necessary or at least the preheating time may be short. Conversely, in cold or humid conditions, preheating may be mandatory for a pleasant user experience.

[004] Different users may have different preferences for one or more properties of the generated aerosol. For example, some users may prefer a more visible exhaled aerosol, while other users may prefer a more discreet amount of visible exhaled aerosol. Some users may prefer a stronger taste compared to other users.

[005] It would be desirable to provide an aerosol generating device that generates the inhalable aerosol under different conditions. It would also be desirable to provide an aerosol generating device capable of providing a variety of types of experiences to a user. It would also be desirable to provide an aerosol generating device that would allow a user to customize a type of experience. It would also be desirable to provide an aerosol generating device that would allow modification of an operating parameter of the aerosol generating device to customize the smoking experience.

[006] According to a first aspect of the present invention, there is provided an aerosol generating device for receiving a mouthpiece. The device comprises a controller for controlling an operational parameter of the aerosol generating device. The controller may be configured to receive an input indicative of the type of mouthpiece received by the device. The device may comprise a sensing element for detecting the type of mouthpiece received by the aerosol generating device. The input may be a signal from the sensing element indicative of the type of mouthpiece detected by the sensing element. The controller is further configured to control the operational parameter of the aerosol generating device based on the detected type of mouthpiece received by the aerosol generating device.

[007] The use of multiple mouthpieces allows for customization of the smoking experience. The different mouthpieces can be adapted to be used in different conditions, such as dry or hot conditions or humid or cold conditions. The mouthpiece, which is used in certain conditions, allows for an optimized smoking experience, since a user can choose to attach a suitable mouthpiece to the aerosol generating device for the given conditions.

[008] Additionally or alternatively, different mouthpieces allow for customization of the smoking experience regardless of weather conditions. For example, a user may wish to maximize aerosol generation in order to experience a dense aerosol. A mouthpiece may in this case be used by the user which is optimized for dense aerosol generation. If a user prefers to remain discreet, another mouthpiece design may be used which reduces aerosol generation and therefore makes it less visible. One mouthpiece design may allow a user to have a strong smoking experience, for example by increasing nicotine delivery, while an additional mouthpiece design may allow for a light smoking experience, for example by decreasing nicotine delivery. Additionally or alternatively, a user may use different types of aerosol-generating articles. For optimal operation, different operating parameters may be chosen for different aerosol-generating articles. These different operating parameters may be controlled by the user using different types of mouthpieces.

[009] The aerosol generating device is configured to realize a different operating parameter based on the type of nozzle received by the aerosol generating device. Thus, the device can implement different operating parameters to deal with different climatic conditions or due to the individual preferences of a user, by using the appropriate nozzle in conjunction with the aerosol generating device. A single aerosol generating device can therefore be used for different purposes and with optimized functionality for different conditions and user preferences by utilizing multiple nozzles of different types.

[0010] The nozzles may be attached to the aerosol generating device by fastening means. The fastening means may be any conventional fastening means, such as a threaded connection or magnets. The aerosol generating device and the nozzles may comprise corresponding fastening means. Fastening means such as a snap-on connection may also be used.

[0011] As used herein, the terms "upstream", "downstream", "proximal" and "distal" are used to describe relative positions of components or portions of components of aerosol-generating devices and mouthpieces relative to the direction in which a user inhales when using them. The mouthpiece may be attached to a proximal end of the aerosol-generating device, which means a downstream end of the aerosol-generating device. This end of the aerosol-generating device faces a user during use of the aerosol-generating device. When a mouthpiece is received by the aerosol-generating device, the generated aerosol may be drawn into a user's mouth through the mouthpiece. If attachment means are provided, the attachment means may be arranged so that an airflow channel provided in the mouthpiece is not blocked by the attachment means, so that air may flow freely through the airflow channel in the mouthpiece toward the user's mouth.

[0012] The sensing element is configured to detect a type of mouthpiece received by the aerosol generating device. The sensing element may be any element known in the art. The sensing element may be disposed at or adjacent to the proximal end of the aerosol generating device to detect the presence and type of a mouthpiece received, attached or otherwise engaged to the proximal end of the aerosol generating device. The mouthpiece may comprise one or more identification elements. The one or more identification elements may be detectable by the sensing element.

[0013] The controller may be part of an electrical circuit, which may comprise a microprocessor. The microprocessor may be a programmable microprocessor. The electrical circuit may comprise additional electronic components. The electrical circuit may be configured to regulate a power supply to the heating element of the aerosol generating device. Power may be supplied to the heating element continuously upon activation of the system or may be supplied intermittently, on a puff-by-puff basis. However, the controller may be configured to only allow power to be supplied to the heating element when the sensing element has detected that a mouthpiece has been received, attached or otherwise engaged with the aerosol generating device. Power may be supplied to the heating element in the form of pulses of electrical current. The controller may be configured to output a signal to one or more elements of the aerosol generating device based on the type of detected mouthpiece received by the aerosol generating device. The controller may be configured to output a signal to the heating element of the aerosol generating device based on the detected nozzle type received by the aerosol generating device.

[0014] The aerosol generating device may comprise a power supply, typically a battery, within a main body of the aerosol generating device. Alternatively, the power supply may be another form of charge storage device, such as a capacitor. The power supply may require recharging and may have a capacity that allows sufficient energy storage for one or more smoking experiences; for example, the power supply may have sufficient capacity to allow continuous generation of the aerosol for a period of about six minutes or for a period that is a multiple of six minutes. In another example, the power supply may have sufficient capacity to allow a predetermined number of puffs or discrete activations of the heater. The power supply may be a lithium ion battery. Alternatively, the power supply may be a nickel metal hydride battery, a nickel cadmium battery, or a lithium-based battery, e.g., lithium cobalt, lithium iron phosphate, lithium titanate, or a lithium polymer battery.

[0015] In all aspects of the disclosure, the heating element of the aerosol generating device may comprise a material having electrical resistance. Suitable electrically resistive materials include, but are not limited to: semiconductors, such as doped ceramics, electrically "conductive" ceramics (such as, for example, molybdenum disilicide), carbon, graphite, metals, metal alloys, and composite materials made of a ceramic material and a metallic material. Such composite materials may comprise doped or undoped ceramics. Examples of suitable doped ceramics include doped silicon carbides. Examples of suitable metals include titanium, zirconium, tantalum, platinum, gold, and silver. Examples of suitable metal alloys include stainless steel, alloys containing nickel, cobalt, chromium, aluminum, titanium, zirconium, hafnium, niobium, molybdenum, tantalum, tungsten, tin, gallium, manganese, gold and iron, and superalloys based on nickel, iron, cobalt, stainless steel, Timetal® and alloys based on iron, manganese and aluminum. In composite materials, the electrically resistive material may optionally be embedded, encapsulated or coated with an insulating material or vice versa, depending on the energy transfer kinetics and the external physiochemical properties required.

[0016] In one or more embodiments, the heating element of the aerosol generating system may be a susceptor element of an induction heating arrangement. The induction heating arrangement may comprise an induction coil and the susceptor element. The susceptor element may be provided as part of the aerosol generating device, as part of the aerosol generating article, or as part of the aerosol generating device and as part of the aerosol generating article. Induction heating arrangements offer advantages and have been proposed in aerosol generating systems. Induction heating arrangements are, for example, described in at least WO95/27411 A1.

[0017] In general, a susceptor is a material that is capable of absorbing electromagnetic energy and converting it to heat. When located in an alternating electromagnetic field, typically eddy currents are induced and hysteresis losses occur in the susceptor causing the susceptor to heat up. Changing electromagnetic fields generated by one or many inductors, e.g. induction coils of an inductive heating device, heat the susceptor, which then transfers heat to the surrounding aerosol-forming substrate, so that an aerosol is formed. Heat transfer may be primarily by heat conduction. Such heat transfer will be best if the susceptor is in close thermal contact with the tobacco material and the aerosol-forming substrate.

[0018] The susceptor may be formed from any material that can be inductively heated to a temperature sufficient to generate an aerosol from the aerosol-forming substrate. A preferred susceptor may comprise or consist of a ferromagnetic material, for example, a ferromagnetic alloy, ferritic iron, or a ferromagnetic steel or stainless steel. A suitable susceptor may be or comprise aluminum. Preferred susceptors may be heated to a temperature in excess of 250 degrees Celsius.

[0019] Preferred susceptors are metal susceptors, e.g. stainless steel. However, susceptor materials may also comprise or be made of graphite, molybdenum, silicon carbide, aluminum, niobium, Inconel alloys (nickel-chromium austenite-based superalloys), metallized films, ceramics such as zirconia, transition metals such as iron, cobalt, nickel, or metalloid components such as boron, carbon, silicon, phosphorus, aluminum.

[0020] Preferably, the susceptor material is a metal susceptor material.

[0021] The susceptor may also be a multi-material susceptor and may comprise a first susceptor material and a second susceptor material. In some embodiments, the first susceptor material may be disposed in physical contact with the second susceptor material. The second susceptor material preferably has a Curie temperature that is below the ignition point of the aerosol-forming substrate. The first susceptor material is preferably used primarily to heat the susceptor when the susceptor is placed in a fluctuating electromagnetic field. Any suitable material may be used. For example, the first susceptor material may be aluminum or may be a ferrous material such as stainless steel. The second susceptor material is preferably used primarily to indicate when the susceptor has reached a specific temperature, that temperature being the Curie temperature of the second susceptor material. The Curie temperature of the second susceptor material may be used to regulate the temperature of the entire susceptor during operation. Suitable materials for the second susceptor material may include nickel and some nickel alloys.

[0022] By providing a susceptor having at least a first and second susceptor material, the heating of the aerosol-forming substrate and the temperature control of the heating can be separated. Preferably, the second susceptor material is a magnetic material having a second Curie temperature that is substantially the same as a maximum heating temperature. That is, it is preferred that the second Curie temperature be approximately the same as the temperature to which the susceptor must be heated in order to generate an aerosol from the aerosol-forming substrate.

[0023] As described in any of the aspects of the present disclosure, the heating element may be part of an aerosol-generating device. The aerosol-generating device may comprise an internal heating element or an external heating element or both, wherein "internal" and "external" refer to the aerosol-forming substrate. An internal heating element may take any suitable form. For example, an internal heating element may take the form of a heating blade. Alternatively, the internal heater may take the form of a coating or substrate with different electroconductive portions or a metal tube with electrical resistance. Alternatively, the internal heating element may be one or more heating needles or columns passing through the center of the aerosol-forming substrate. Other alternatives include a heating wire or filament, for example, a Ni-Cr (nickel-chromium), platinum, tungsten or alloy wire, or a heating plate. Optionally, the internal heating element may be placed within or on a rigid carrier material. In such an embodiment, the electrical resistance heating element may be formed using a metal having a defined relationship between temperature and resistivity. In one example of such a device, the metal may be formed as a strip of a suitable insulating material, such as a ceramic material, and then sandwiched between another insulating material, such as glass. Heaters formed in this manner may be used to both heat and monitor the temperature of the heating elements during operation.

[0024] An external heating element may take any suitable form. For example, an external heating element may take the form of one or more flexible heating sheets on a dielectric substrate, such as polyimide. The flexible heating sheets may be shaped to fit the perimeter of the heating chamber of the aerosol generating device. Alternatively, an external heating element may take the form of a metal grid or grids, a flexible printed circuit board, a molded interconnect device (MID), ceramic heater, flexible carbon fiber heater, or may be formed using a coating technique, such as plasma vapor deposition, on a suitably shaped substrate. An external heating element may also be formed using a metal that has a defined relationship between temperature and resistivity. In one example of such a device, the metal may be formed as a strip between two layers of suitable insulating materials. An external heating element formed in this manner may be used both to heat and to monitor the temperature of the external heating element during operation.

[0025] The internal or external heating element may comprise a heat sink or heat reservoir containing a material capable of absorbing and storing heat and subsequently releasing the heat over time to the aerosol-forming substrate. The heat sink may be formed from any suitable material, such as a suitable metallic or ceramic material. In one embodiment, the material has a high heat capacity (sensible heat storage material) or is a material capable of absorbing and subsequently releasing heat via a reversible process, such as a high temperature phase change. Suitable sensible heat storage materials include silica gel, alumina, carbon, glass mat, fiberglass, minerals, a metal or metal alloy such as aluminum, silver or lead, and a cellulosic material such as paper. Other suitable materials that release heat via a reversible phase change include paraffin, sodium acetate, naphthalene, wax, polyethylene oxide, metal, metal salt, a eutectic mixture of salts, or an alloy. The heat sink or heat reservoir may be arranged so that it is in direct contact with the aerosol-forming substrate and can transfer the stored heat directly to the substrate. Alternatively, the heat stored in the heat sink or heat reservoir may be transferred to the aerosol-forming substrate via a heat conductor such as a metal tube.

[0026] The heating element favorably heats the aerosol-forming substrate by means of conduction. The heating element may be at least partially in contact with the substrate or the carrier on which the substrate is deposited. Alternatively, heat from an internal or external heating element may be conducted to the substrate by means of a heat-conducting element.

[0027] Instead of a heating element, an atomizer may be provided for atomizing the liquid aerosol-forming substrate to form an aerosol, which may subsequently be inhaled by a user. The atomizer may comprise a heating element, in which case the atomizer is referred to as a vaporizer. In general, the atomizer may be configured as any device that is capable of atomizing the liquid aerosol-forming substrate. For example, the atomizer may comprise a nebulizer or a Venturi-based atomizing nozzle for atomizing the liquid aerosol-forming substrate. Thus, atomization of the liquid aerosol-forming substrate may be accomplished by a non-thermal aerosolization technique. A mechanical vibratory vaporizer with vibrating elements, vibrating meshes, a piezo-driven nebulizer, or surface acoustic wave aerosolization may be used.

[0028] As used herein, the term “aerosol-generating article” is used to denote an aerosol-forming substrate that is capable of releasing volatile compounds that can form an aerosol. For example, an aerosol-generating article may be a smoking article that generates an aerosol directly inhalable into a user's lungs through the user's mouth. An aerosol-generating article may be disposable. A smoking article composed of an aerosol-forming substrate containing tobacco is called a tobacco stick.

[0029] The aerosol-generating article may be substantially cylindrical in shape. The aerosol-generating article may be substantially elongated. The aerosol-generating article may have a length and a circumference substantially perpendicular to the length. The aerosol-forming substrate may be substantially cylindrical in shape. The aerosol-forming substrate may be substantially elongated. The aerosol-forming substrate may also have a length and a circumference substantially perpendicular to the length.

[0030] For example, the aerosol-generating article may have an overall length of between approximately 30 mm and approximately 100 mm. The aerosol-generating article may have an outer diameter of between approximately 5 mm and approximately 12 mm. The aerosol-generating article may comprise a filter plug. The filter plug may be located at the downstream end of the aerosol-generating article. The filter plug may be a cellulose acetate filter plug. The filter plug may be a hollow acetate tube. In one embodiment, the filter plug is approximately 7 mm in length, but may have a length of between approximately 5 mm and approximately 10 mm. If a hollow acetate tube is used, the hollow acetate tube may have a length of between 10 mm and 25 mm. The aerosol-generating article may comprise a substrate section, which preferably directly abuts the filter plug or the hollow acetate tube. In one embodiment, the aerosol-generating article has an overall length of approximately 45 mm.

[0031] As used herein, the term "aerosol-forming substrate" refers to a substrate capable of releasing volatile compounds that can form an aerosol. Such volatile compounds may be released by heating the aerosol-forming substrate. The aerosol-forming substrate may conveniently be part of an aerosol-generating article or a smoking article.

[0032] The aerosol-forming substrate may be a solid aerosol-forming substrate. Alternatively, the aerosol-forming substrate may comprise solid and liquid components. The aerosol-forming substrate may comprise a tobacco-containing material containing volatile tobacco flavoring compounds that are released from the substrate upon heating. Alternatively, the aerosol-forming substrate may comprise a non-tobacco material. The aerosol-forming substrate may further contain an aerosol former that facilitates the formation of a dense and stable aerosol. Examples of suitable aerosol formers are glycerin and propylene glycol.

[0033] If the aerosol-forming substrate is a solid aerosol-forming substrate, the aerosol-forming substrate may comprise, for example, one or more of: powder, granules, pellets, pieces, strands, strips or sheets containing one or more of: herbal leaf, tobacco leaf, tobacco twig fragments, reconstituted tobacco, homogenized tobacco, extruded tobacco, reconstituted tobacco and expanded tobacco. The solid aerosol-forming substrate may be in loose form or may be supplied in a suitable container or cartridge. Optionally, the solid aerosol-forming substrate may contain additional volatile flavoring compounds with or without tobacco to be released upon heating of the substrate. The solid aerosol-forming substrate may also contain capsules which, for example, include the additional volatile flavoring compounds of tobacco or without tobacco and such capsules may melt upon heating of the solid aerosol-forming substrate.

[0034] As used herein, homogenized tobacco refers to material formed by agglomerating particulate tobacco. The homogenized tobacco may be in the form of a sheet. The homogenized tobacco material may have an aerosol-forming content of greater than 5% by dry weight. Alternatively, the homogenized tobacco material may have an aerosol-forming content of between 5% and 30% by dry weight. Sheets of homogenized tobacco material may be formed by agglomerating tobacco particles obtained by grinding or otherwise combining tobacco leaf blades and tobacco leaf stems. Alternatively or additionally, the sheets of homogenized tobacco material may comprise one or more of tobacco dust, tobacco trimmings, and other particulate tobacco by-products formed during, for example, the processing, handling, and shipping of tobacco. Sheets of homogenized tobacco material may comprise one or more intrinsic binders, i.e., endogenous tobacco binders, one or more extrinsic binders, i.e., exogenous tobacco binders, or a combination thereof, in order to help agglomerate the tobacco particles; alternatively or additionally, the sheets of homogenized tobacco material may contain other additives including, but not limited to, tobacco and non-tobacco fibers, aerosol formers, humectants, plasticizers, flavorings, fillers, aqueous and non-aqueous solvents, and combinations thereof.

[0035] Optionally, the solid aerosol-forming substrate may be provided or incorporated into a thermally stable carrier. The carrier may be in the form of powder, granules, pellets, filaments, pieces, strips or sheets. Alternatively, the carrier may be a tubular carrier and contain a thin layer of the solid substrate deposited on its inner surface or on its outer surface or on both its inner and outer surfaces. This tubular carrier may be formed, for example, of a paper or paper-like material, a non-woven carbon fibre web, a low mass open mesh wire mesh, a perforated metal foil or any other thermally stable polymeric matrix.

[0036] In a particularly preferred embodiment, the aerosol-forming substrate is formed from a crimped sheet of homogenized tobacco material. As used herein, the term "crimped sheet" denotes a sheet having a plurality of substantially parallel edges or corrugations. Preferably, when the aerosol-generating article is assembled, the substantially parallel edges or corrugations extend along or parallel to the longitudinal axis of the aerosol-generating article. This advantageously facilitates the assembly of the crimped sheet of homogenized tobacco material to form the aerosol-forming substrate. However, it will be appreciated that the crimped sheets of homogenized tobacco material for inclusion in the aerosol-generating article may, alternatively or additionally, have a plurality of substantially parallel edges or corrugations arranged at an acute or obtuse angle to the longitudinal axis of the aerosol-generating article when the aerosol-generating article is assembled. In certain embodiments, the aerosol-forming substrate may comprise a bundled sheet of homogenized tobacco material that has a substantially uniform texture over substantially its entire surface. For example, the aerosol-forming substrate may comprise a bundled crimped sheet of homogenized tobacco material comprising a plurality of substantially parallel ridges or corrugations that are substantially uniformly spaced apart across the entire width of the sheet.

[0037] The solid aerosol-forming substrate may be deposited on the surface of the carrier in the form of, for example, a sheet, foam, gel or slurry. The solid aerosol-forming substrate may be deposited over the entire surface of the carrier or, alternatively, may be deposited in a pattern to provide non-uniform aroma distribution during use.

[0038] During use, in some embodiments, the aerosol-generating article may be contained by the aerosol-generating device. The mouthpiece may be received by, attached to, or otherwise engaged with the aerosol-generating device. The heating chamber of the aerosol-generating device may be disposed proximate to the proximal end of the aerosol-generating device. The aerosol-generating article may be partially or fully inserted into the heating chamber of the aerosol-generating article during use. When a mouthpiece is attached to the device, the aerosol-generating article may be partially received in the mouthpiece. During use, a user may inhale on the mouthpiece and not directly on the aerosol-generating article. The mouthpiece may be attached directly to the aerosol-generating device. Alternatively, an intermediate member may be positioned between the aerosol-generating device and the mouthpiece. The intermediate member may be part of the mouthpiece, in which case the mouthpiece would be a two-piece member. The intermediate element may be used to control the mode of operation of the aerosol generating device as described above. This has the advantage that it may not be necessary to provide multiple nozzles for the different modes of operation of the aerosol generating device, but that only multiple intermediate elements may be required. Therefore, the intermediate elements may comprise one or more identification elements that enable the detection element of the aerosol generating device to identify a type of intermediate element.

[0039] The term "operational parameter" denotes a parameter that influences how the aerosol is generated during use of the aerosol-generating device. It will be appreciated that "how the aerosol is generated" may refer to any one or more properties of the aerosol, or the user experience, or both. For example, this may include a duration of a user experience. In some embodiments, the operational parameter may comprise one or more of: a maximum operating temperature for the heating element, the temperature of the heating element over time, the resistance of the heating element, the resistance of the heating element over time, the power supplied to the heating element, the power supplied to the heating element over time, a maximum heating time per puff, a minimum time between puffs, a maximum number of puffs per aerosol-generating article, an airflow rate through the device, and a maximum total heating time for the aerosol-generating article. In some embodiments, the operating parameter may comprise a duration of time to preheat the heating element. The operating parameter may comprise one of the above parameters for a preheating period of the heating element. Establishing an operating parameter customized to specific user conditions or preferences may be advantageous because the aerosol-forming substrates in specific aerosol-generating articles may require, or provide, an improved smoking experience with specific heating conditions. Alternatively, or in addition, to controlling a single operating parameter, the controller may be configured to control multiple operating parameters. The controller may be configured to control multiple operating parameters over time. The controller may be configured to control an operating regime of the aerosol-generating device. An operating regime may comprise multiple operating parameters over time. In some embodiments, “operating parameter” may refer to a temperature profile of the heating element. The term “temperature profile” may refer to any one or combination of more than one of the above operating parameters. For example, "temperature profile" may refer to any of the following: a heating element temperature over time, a heating element temperature gradient over time, a heating element power applied over time, a heating element resistance over time, a maximum heating time per puff, and a maximum total heating time per aerosol-generating article.

[0040] In some embodiments, the operating parameter may comprise a "boost power mode". A "boost power mode" may refer to a mode in which additional electrical power is supplied to the heating element. In this mode, the controller may be configured to control the supply of the power supply to the heating element such that more electrical power is supplied to the heating element. Alternatively, or additionally, the aerosol generating device may comprise one or more additional power supplies. An additional power supply may have a configuration similar to the main power supply described above. An additional power supply may be a battery. The controller may be configured to control the flow of electrical power from one or more additional power supplies to the heating element. Preferably, the controller is configured to control the flow of electrical power from the main power supply as described above and from one or more additional power supplies to the heating element. Electrical power from the main power supply and one or more additional power supplies may be supplied to the heating element through common electrical contacts.

[0041] A "power boost mode" may be used to rapidly heat the heating element to a desired temperature, for example, during a user's puff. A "power boost mode" may be used to heat an aerosol-forming substrate that requires additional heat.

[0042] A "power boost mode" may be utilized based on the type of nozzle detected. Depending on the type of nozzle detected, a "power boost mode" may be activated at the beginning or at any time during an operation of the device. Additionally or alternatively, a "power boost mode" may be inhibited at any time during an operation of the device. The type of nozzle may determine when during operation of the device a "power boost mode" may be utilized.

[0043] A "power boost mode" may advantageously be employed if the aerosol-generating device can be configured to receive multiple aerosol-generating articles. In this regard, in some embodiments, the aerosol-generating device may be configured to receive multiple aerosol-generating articles. The aerosol-generating articles may be of the same type or of a different type, for example, they may comprise different aerosol-forming substrates. The aerosol-generating device may comprise one or more of: multiple heating chambers, multiple heating elements, multiple controllers, and multiple power supplies to facilitate operation with multiple aerosol-generating articles. If more than one aerosol-generating article is received in the aerosol-generating device and it is desired to heat the aerosol-forming substrates in the aerosol-generating articles, a "power boost mode" may be utilized. The "power boost mode" may be used so that additional electrical power may be supplied to multiple aerosol generating articles. Preferably, at least one additional power source is used for this purpose. As an example, the main power source may be used to supply power to a first aerosol generating article received in the aerosol generating device and an additional power source may be used to supply power to a second aerosol generating article received in the aerosol generating device. A "power boost mode" may be used to supply additional electrical power to a single heating element or to supply electrical power to multiple heating elements or to supply electrical power to multiple heating elements and additional electrical power to each of the multiple heating elements.

[0044] In embodiments employing induction heating arrangements, the term "operational parameter" may also indicate one or more parameters relating specifically to induction heating. Induction heating arrangements typically comprise an induction coil and a susceptor, which function as a heating element. Accordingly, an operational parameter controlled depending on the type of nozzle detected may, in some embodiments, be one or more parameters of an induction coil, such as any one of or any combination of two or more of: coil frequency, applied electrical voltage, applied electrical current, and applied power.

[0045] In some embodiments, the term "operational parameter" may also denote one or more parameters related to user interface properties, such as optical, acoustic, haptic, or other sensory properties of the aerosol-generating device. For example, the aerosol-generating device may comprise optical elements, such as LEDs, that may be controlled to produce a specific light pattern depending on the type of nozzle detected by the aerosol-generating device. The aerosol-generating device may also comprise vibratory elements that may produce a specific haptic pattern depending on the type of nozzle detected by the aerosol-generating device.

[0046] The controllable user interface property may be pre-programmed or may be user programmable. Programming of the device may be accomplished through an application via an external computer or a personal device such as a tablet or cell phone. By allowing the user to choose a desired user interface property from a plurality of options, each user may individually design the behavior of his or her aerosol generating device.

[0047] The sensing element may comprise one or more of an optical recognition element, a bar code reader, an RFID reader, a poka yoke, a conductor, a resistor or an inductor. The different types of nozzles to be detected by the sensing element may comprise corresponding identification elements.

[0048] In some embodiments, the identification element may comprise one or more of a barcode, a pattern, an RFID tag, a poka yoke, a tag, a conductor or conductive adhesive, a resistivity value, a resistor, an area with different resistance relative to the rest of the nozzle, a condenser, a capacitor, a capacitance, a susceptor material, or an inductive element.

[0049] The term "type" of a nozzle may refer to one or more properties, features, or characteristics of the nozzle. One or more properties may include an identification element, such as a barcode, an RFID tag, a poka yoke, a tag, a conductor, a resistor, or an induction element of a nozzle. One or more properties may include a pattern, a structure, a texture, or a material of a nozzle.

[0050] The sensing element may be any of: a mechanical device, an optical device, an opto-mechanical device, and a microelectrical mechanical systems (MEMS)-based sensor. The optical recognition element of the sensing element may comprise at least one light emitter and at least one light sensor. The sensing element may include more than one light sensor in the form of a one-dimensional (e.g., linear) array of light sensors. The sensing element may comprise more than one light sensor in the form of a two-dimensional array of light sensors. The sensing element may comprise multiple light emitters.

[0051] The nozzle identification elements may each comprise a tag, which may comprise an identifiable spectroscopic signature. The tag may be incorporated within a material of the nozzle. This identifiable spectroscopic signature may be used in conjunction with the sensing element of the aerosol generating device comprising at least one light emitter and at least one light sensor. The tag may comprise an identifiable spectroscopic signature upon absorption. When the tag is illuminated by the light emitter of the sensing element, the tag may absorb a specific wavelength or set of wavelengths, and the wavelengths of light subsequently received by the light sensor may allow the sensing element of the aerosol generating device to determine the tag and therefore the type of nozzle received depending on the missing wavelengths. The physical and chemical structure of the tag may be controlled so that the wavelength of light absorbed may be defined as required. The absorbed wavelength of light may not be in the visible spectrum. Preferably, the absorbed wavelength is in the infrared or ultraviolet range.

[0052] The tag may comprise an identifiable spectroscopic signature in the emission. When the tag is illuminated by the light emitter of the sensing element of the aerosol generating device, the light preferentially excites the tag such that the tag emits at least one wavelength of light, alternate from the wavelength of the excitation light. As will be appreciated, this is a form of photoluminescence and may be phosphorescence or fluorescence. By controlling the physical and chemical structure of the tag the spectroscopic signature may be controlled. In some embodiments, the identifiable signature may depend on the response time of the emissions to the stimulus or the rate of decay of the emission after the stimulus. The wavelength of the emitted light may not be in the visible spectrum. Preferably, the wavelength of the emitted light is in the infrared or ultraviolet range. The emitted light may be detected by the light sensor of the sensing element to detect the type of nozzle received. The sensing element may determine the nozzle type by comparing the spectroscopic signature of the detected tag with a lookup table of spectroscopic tag signatures corresponding to different nozzle types.

[0053] The tagging may be a powder composed of at least one of: a rare earth; an actinide metal oxide; a ceramic. The rare earth is preferably a lanthanide.

[0054] The nozzle identification elements may each comprise black marks. The identification elements may include different grey levels. Different grey levels may be generated by varying the ink dose or by printing in dots that are smaller than the minimum line size resolvable by the sensing element. The identification elements may comprise a one-dimensional barcode. Each line in the barcode may extend around a portion of the nozzle, so that the nozzle can be received by, preferably attached to, the aerosol generating device in any orientation. Alternatively, a two-dimensional barcode may be used. The nozzle identification element may additionally or alternatively comprise a QR code, an NFC tag or an RFID tag. The sensing element may comprise corresponding sensors.

[0055] The identification elements of the different types of nozzles may each comprise an RFID tag. RFID tags may advantageously be passive, i.e., they do not require battery power to be used. An RFID tag may be interrogated by an electrical RFID reader as known in the art. The sensing element of the aerosol generating device may comprise an RFID reader. The RFID reader may scan the RFID tag to determine the resonant frequency of the tag, which may be correlated with the type of nozzle. The RFID reader may be configured to interrogate the RFID tag at one or more discrete frequencies. The sensing element of the aerosol generating device may include any suitable number of RFID readers to obtain signals from one or more RFID tags. An RFID reader may interrogate and read more than one RFID tag.

[0056] The sensing element of the aerosol generating device may include one or more conductors, preferably pairs of conductors, defining at least a portion of one or more circuits. The conductors may be electrically selectively coupleable with one or more conductors of the nozzle identification elements when a nozzle is received by the aerosol generating device. Attachment of a nozzle to the aerosol generating device may close one or more of the circuits. One or more circuits may be indicative of the type of nozzle received.

[0057] The nozzle identification elements may each include one or more resistors. After a nozzle is received by the aerosol generating device, the electrical resistance of the resistors may be determined by the sensing element of the aerosol generating device. The resistor may also have a different resistance area relative to the rest of the nozzle. This information may be used to determine the resistance of the resistors and therefore identify the type of nozzle received.

[0058] The nozzle identification elements may each comprise a microchip with a wireless transceiver that communicates identification information to the sensing element of the aerosol generating device.

[0059] The sensing element may comprise an inductor. In this case, the nozzle identification elements may each comprise a corresponding induction element, such as susceptor material. A probing induction current may be used in this regard by the sensing element to identify the type of nozzle received.

[0060] The aerosol-generating device may comprise a heating chamber for receiving an aerosol-generating article containing an aerosol-forming substrate. The aerosol-generating device may comprise a heating element configured to heat an aerosol-forming substrate of an aerosol-generating article when the aerosol-generating article is received by the aerosol-generating device, preferably inserted into the heating chamber. The operational parameter of the aerosol-generating device may comprise the temperature profile of the heating element during heating.

[0061] Said control of the operational parameter of the aerosol generating device may comprise selecting one or more properties of the temperature profile based on the detected type of received nozzle. Said at least one or more properties may comprise any of: a duration of the preheating period; a target temperature for a preheating period; a change in temperature over time during a preheating period; a change in temperature over time during a session of use of the aerosol generating device; one or more target temperatures during a session of use; and a duration of a session of use.

[0062] At least a first and a second temperature profile may be stored in a memory medium. In some embodiments, the aerosol-generating device may comprise a memory medium. In some embodiments, the aerosol-generating device comprises a means for accessing a memory by a remote device. In some embodiments, the remote device may be a server, a computer, a personal computing device such as a tablet or a cell phone. In some embodiments, the means for accessing a memory on the remote device may comprise wireless communication media such as Bluetooth® or other wireless communication protocols. Controlling an operational parameter may comprise selecting a predefined temperature profile from a memory device based on the nozzle type received by the aerosol-generating device. In some embodiments, controlling an operational parameter may comprise selecting a predefined temperature profile from a database or lookup table stored in the memory based on the detected nozzle type received by the aerosol-generating device. The first temperature profile may comprise a shorter preheat period and then the second temperature profile. The duration of the preheat period of the first temperature profile may be a maximum duration of 70%, preferably 50%, more preferably 30% of the duration of the preheat period of the second temperature profile. Memory may be connected to the controller. The controller may be configured to operate the heating element based on the received detected nozzle and operating parameter, such as one or more temperature profiles stored in memory.

[0063] A preheating period may be necessary or advisable for aerosol generation. In this regard, preheating may reduce the response time once the user wishes to generate the aerosol. Whether or not preheating is advisable depends on climatic conditions, such as temperature or humidity. A specific nozzle may be received by the aerosol-generating device, wherein this nozzle may correspond to a first temperature profile. Thus, if the sensing element of the aerosol-generating device detects this nozzle, the controller of the aerosol-generating device will control the heating of the heating element of the aerosol-generating device in accordance with the first temperature profile. The first temperature profile with a shorter preheating period may be used in dry or hot climates. A second nozzle may be used for a second temperature profile. After the nozzle received by the aerosol-generating device is detected by the sensing element, the controller may use a second temperature profile for heating the heating element of the aerosol-generating device. This second temperature profile can be used in humid or cold conditions to optimize aerosol generation.

[0064] At least a third and a fourth temperature profile may be stored in a memory. Controlling an operational parameter may comprise selecting a predefined temperature profile from a look-up table stored in the memory, based on the detected nozzle type received by the aerosol generating device. The third temperature profile may be configured to transfer less heating energy to an aerosol generating article inserted into the heating chamber than the fourth temperature profile. The heating energy transmitted from the third temperature profile may be at most 70%, preferably 50%, more preferably 30% of the heating energy transmitted from the fourth temperature profile.

[0065] The term "heating energy" may indicate the total energy emitted from the heating element during a user's puff. The heating energy may be a function of the temperature of the heating element over the time of a puff. The heating energy may vary depending on the smoking experience the user desires. The user may use different mouthpieces for these different smoking experiences. For a lighter smoking experience in which a puff contains one or more of less aerosol, less dense aerosol, or less nicotine, a user may attach a mouthpiece to the aerosol generating device corresponding to the third temperature profile. During subsequent aerosol generation from the aerosol generating device, less aerosol or less dense aerosol or aerosol containing less nicotine will be generated due to the lower heating energy. If a user desires a more intense smoking experience, the user may attach a different mouthpiece to the aerosol generating device corresponding to the fourth temperature profile. More heating energy may be emitted by the heating element at this temperature profile to create one or more of an aerosol, a denser aerosol or an aerosol containing more nicotine.

[0066] The invention also relates to a non-transitory computer-readable medium comprising a set of instructions for causing the controller of the aerosol generating device, as described above, to execute said operating parameter based on the detected nozzle type received by the aerosol generating device.

[0067] The invention also relates to a mouthpiece for an aerosol generating device as described above. The mouthpiece may be configured to be received by the aerosol generating device. The mouthpiece may comprise an identification element indicative of the type of mouthpiece. The identification element is detectable by the aerosol generating device when the mouthpiece is received by the aerosol generating device. The mouthpiece may comprise a label configured to allow user identification of the type of mouthpiece. The label of the mouthpiece may be one or more of a visual indicator, such as a color of the mouthpiece, a logo, symbol, image, pattern and haptic structure on at least a portion of the mouthpiece, a texture of the mouthpiece and a packaging provided with the mouthpiece.

[0068] The mouthpiece may comprise fastening means corresponding to the fastening means of the aerosol generating device. For example, the mouthpiece may comprise male threads, while the aerosol generating device may comprise female threads or vice versa. Fastening means such as magnetic or quick-fit connections may be used.

[0069] The mouthpiece identification element may correspond to the detection element of the aerosol generating device, such that the detection element of the aerosol generating device can identify the type of mouthpiece received by the aerosol generating device. Therefore, the identification element may be an element corresponding to one or more of an optical recognition element, a bar code reader, an RFID reader, a poka yoke, a tag, a conductor, a resistor, or an inductor.

[0070] The invention also relates to a nozzle or a set of nozzles, which may comprise at least a first and a second nozzle. Each nozzle may comprise an air flow channel. The nozzles may be configured to cool the air flowing through the air flow channels. The air flow channels of the nozzles may be configured such that the air flow channel of the first nozzle cools the air flowing through the air flow channel of the first nozzle more strongly than the air flowing through the air flow channel of the second nozzle.

[0071] These different mouthpieces can be used to facilitate different smoking experiences. The first mouthpiece cooling the air flowing through the airflow channel stronger than the second mouthpiece cooling the air flowing through the airflow channel of the second mouthpiece can lead to the generation of a different aerosol. In this aspect, the aerosol is generated by the formation of liquid droplets in air drawn from outside the system through or near the heating chamber and further towards the airflow channel of the mouthpiece. The volatilized aerosol-forming substrate is entrained by the airflow. The volatilized aerosol-forming substrate forms the liquid droplets predominantly during the cooling of the airflow. Therefore, stronger cooling of the first mouthpiece can result in the formation of more or larger droplets. In this way, a stronger or denser aerosol can be generated. If a user desires a lighter smoking experience, the user can attach the second mouthpiece to the aerosol generating device, which cools the air flowing through the less powerful airflow channel. Consequently, a lighter or less dense aerosol can be generated for inhalation by the user.

[0072] The invention also relates to a system comprising an aerosol generating device as described above and a nozzle as described above or a set of nozzles as described above.

[0073] The system may comprise an aerosol-generating article comprising an aerosol-forming substrate, the aerosol-generating article for use with the aerosol-generating device, and the mouthpiece or mouthpiece assembly.

[0074] The invention also relates to a method for controlling an operational parameter of an aerosol generating device, the method comprising:

[0075] detecting a type of nozzle received by an aerosol generating device; and

[0076] controlling an operational parameter of the aerosol generating device based on the type of detected nozzle received by the aerosol generating device.

[0077] The method may comprise the step of providing an aerosol generating device as described above.

[0078] The method may comprise the step of providing a nozzle as described above.

[0079] The method may comprise the step of engaging the mouthpiece with the aerosol generating device.

[0080] The method may further comprise the steps of:

[0082] determining a type of nozzle engaged with the aerosol generating device based on said signal;

[0083] providing an output for controlling said operational parameter of the aerosol generating device.

[0084] The method may comprise the step of controlling one or more of: a maximum operating temperature for the heating element, the temperature of the heating element over time, the resistance of the heating element, the resistance of the heating element over time, the power supplied to the heating element, the power supplied to the heating element over time, a maximum heating time per puff, a minimum time between puffs, a maximum number of puffs per aerosol-generating article, an airflow rate through the device, a duration of a preheating period, a target temperature for a preheating period, a temperature change over time during a preheating period, a temperature change over time during a session of use of the aerosol-generating device, one or more target temperatures during a session of use, a time duration of a session of use, and a maximum total heating time for the aerosol-generating article.

[0085] The method may comprise the step of selecting a predefined temperature profile.

[0086] The method may comprise the step of selecting a predefined temperature profile from a lookup table stored in a memory of the aerosol generating device.

[0087] The invention also relates to a non-transitory computer readable medium comprising a set of instructions for causing a controller as described above to perform the method as described above. The invention also relates to a non-transitory computer readable medium comprising a set of instructions for causing an aerosol generating device as described above to perform the method as described above. The invention also relates to a non-transitory computer readable medium comprising a set of instructions for causing an aerosol generating system as described above to perform the method as described above.

[0088] The invention also relates to a controller for controlling operation of an aerosol generating device as described above, the controller comprising: input means for receiving an input signal indicative of a type of nozzle coupled with the aerosol generating device;

[0089] processing means for determining a type of mouthpiece engaged with the aerosol generating device based on said input signal, wherein said processing means is configured to determine a desired operating parameter of the aerosol generating device based on said determined type of mouthpiece engaged with the aerosol generating device; output means for providing an output signal for controlling said determined operating parameter.

[0090] The operational parameter may be substantially as described above with reference to the aerosol generating device. Features described with respect to one aspect may be equally applicable to other aspects of the invention.

[0091] The invention will be described in more detail, by way of example only, with reference to the attached figures, in which:

[0092] Figure 1 shows a cross-sectional view of an aerosol-generating device, an aerosol-generating article and a mouthpiece, according to an embodiment of the invention;

[0093] Figure 2 shows a disassembled configuration of an aerosol generating device, an aerosol generating article, a mouthpiece and an intermediate element, according to an embodiment of the invention;

[0094] Figure 3 shows an assembled configuration of the elements shown in Figure 2;

[0095] Figure 4 shows another embodiment of the invention with an aerosol generating device and an attached mouthpiece; and

[0096] Figure 5 shows a disassembled configuration of the elements shown in Figure 4.

[0097] Figure 1 shows an aerosol generating device 10 and a mouthpiece 12. The aerosol generating device 10 comprises a fastening means 14 for attaching the aerosol generating device 10 to the mouthpiece 12. The mouthpiece 12 comprises a corresponding fastening means 16 for facilitating attachment with the aerosol generating device 10.

[0098] Multiple different types of mouthpieces 12 may be attached to the aerosol generating device 10. The type of mouthpiece 12 is indicated by a label 18. The label 18 may, for example, be color-coded. A user may be able to identify the type of mouthpiece 12 by looking at or touching the label 18.

[0099] The aerosol generating device 10 comprises a sensing element 20 configured to identify the type of mouthpiece 12 connected to the aerosol generating device 10. The mouthpiece 12 comprises a corresponding identification element 22 which enables the sensing element 20 of the aerosol generating device 10 to identify the type of mouthpiece 12 connected to the aerosol generating device 10.

[00100] Different types of nozzles 12 are provided to allow selection of an operating parameter of the aerosol generating device 10. The aerosol generating device 10 comprises a controller 24 configured to control the operating parameter of the aerosol generating device 10 based on the detected attached nozzle 12. The operating parameter may be the temperature profile of a heating element of the aerosol generating device. The operating parameter of the aerosol generating device 10 is preferably one or more parameters or properties related to the specific operation of the heating element disposed within or around a heating chamber 26 of the aerosol generating device 10. The operation of the heating element may include the maximum temperature reached by the heating element during operation. The operation of the heating element may include the length of operation of the heating element. The operation of the heating element may include a preheating operation and a length and temperature of a preheating operation of the heating element.

[00101] The heating element of the aerosol generating device 10 is configured to heat an aerosol generating article 28 for aerosol generation. The aerosol generating article 28 may be inserted into the heating chamber 26 of the aerosol generating device 10. The aerosol generating article 28 may be sandwiched between the aerosol generating device 10 and the mouthpiece 12. A user may puff on the mouthpiece 12 to inhale the generated aerosol. The connecting means 14, 16 of the aerosol generating device 10 and the mouthpiece 12 may be configured to facilitate an airtight connection between the aerosol generating device 10 and the mouthpiece 12. The airtight connection may force air to be drawn from an air inlet of the aerosol generating device 10 through the heating chamber 26 and the aerosol generating article 28 toward the mouthpiece 12. In other words, the airtight connection between the mouthpiece 12 and the aerosol generating device 10 may prevent airflow between the aerosol generating device 10 and the mouthpiece 12 other than the above-described desired airflow through the aerosol generating article 28.

[00102] The heating chamber 26 may be configured such that an aerosol-generating article 28 inserted into the heating chamber 26 is received in the heating chamber 26 in a tight manner. The mouthpiece 12 may comprise a cavity 30 for receiving a portion of an aerosol-generating article 28. If the mouthpiece 12 and the aerosol-generating device 10 are connected to each other, an aerosol-generating article 28 may be partially inserted into the heating chamber 26 and partially received in the cavity 30 of the mouthpiece 12.

[00103] The heating element may be powered by a power source 32, such as a battery. The power source 32 may be disposed in the aerosol generating device 10.

[00104] Figure 2 shows a separate configuration of the aerosol generating device 10 and the mouthpiece 12. Additionally, Figure 2 shows an intermediate element 34. The intermediate element 34 is preferably part of the mouthpiece 12, so that the mouthpiece is provided as a two-piece element. The intermediate element 34 may be used to control an operational parameter of the aerosol generating device 10. In this regard, the intermediate element 34 may comprise an identification element 22 and a label 18, as described above in relation to the mouthpiece 12. In this embodiment, a user may use a single aerosol generating device 10 and a single mouthpiece 12 and adapt the operation of the aerosol generating device 10 by choosing the appropriate intermediate element 34. The intermediate member 34 may comprise attachment means for securing the intermediate member 34 to the aerosol generating device 10 and the mouthpiece 12. The intermediate member 34 may also be used for design customization using different colors or haptic structures. The intermediate member 34 may be used to improve grip by providing a structured surface on the outer perimeter of the intermediate member 34.

[00105] Figure 3 shows an assembled configuration of the elements shown in Figure 2. As can be seen in Figure 3, the aerosol-generating article 28 is contained by the mouthpiece 12, the aerosol-generating device 10, and the intermediate element 34. If no intermediate element 34 were to be used, as shown in the embodiment of Figure 1, the aerosol-generating device 10 and the mouthpiece 12 would be sized to surround the aerosol-generating article 28 after assembly.

[00106] Figures 4 and 5 show a different embodiment, in which the mouthpiece 12 does not comprise a cavity 30 for partially receiving the aerosol-generating article 28. In this embodiment, the aerosol-generating article 28 is completely received in the heating chamber 26 of the aerosol-generating device 10, while the mouthpiece 12 only closes the proximal end of the heating chamber 26. Figures 4 and 5 also show other potential elements, such as one or more buttons 36 for controlling the operation of the aerosol-generating device 10 and seals 38 for preventing unwanted airflow. In Figure 4, the mouthpiece 12 is connected to the aerosol-generating device 10, while in Figure 5, the mouthpiece 12 is separate from the aerosol-generating device 10.
