Description

Control method, control device and aerosol generating device of aerosol generating device

technical field

The invention belongs to the technical field related to the control of a simulated smoking device, in particular to a control method of an aerosol generating device, a control device and an aerosol generating device.

Background technique

The aerosol generating device is a relatively common simulated cigarette electronic product, mainly used for smoking cessation and replacing cigarettes; the structure of the aerosol generating device mainly includes a battery rod and an atomizing head; when a smoker's smoking action is detected, the battery rod Supply power to the atomizing head to make the heating wire of the atomizing head heat up, and the smoke oil is heated, evaporated and atomized to form an aerosol that simulates smoke, so that the user has a feeling similar to real smoke when inhaling the sol generating device.

In order to avoid dry burning, the existing aerosol generating devices usually directly detect the temperature and resistance of the heating wire, and control the output power according to the temperature of the heating wire. In recent years, most of the oil-conducting cotton in the current atomizing head is made of cotton or non-woven fabric, which is in direct contact with the heating wire. The temperature of the heating wire is between 150 and 315 degrees when it is working. higher. The high temperature resistance of cotton is very low, and the carbonization temperature and ignition point are very low. Under normal oil supply conditions, the service life of cotton is also limited. Cotton will carbonize under high temperature for a long time, and carbon deposits will accumulate on the surface of the heating wire. The overall resistance of the heating wire with carbon deposits will be greater than that without carbon deposits. Correspondingly, under the same output power, The temperature of the heating wire with carbon deposits is higher, so that the aerosol generating device where the entire atomizing head is located will be misjudged, and the output power is more likely to return to zero in advance. In the case of e-liquid, the output is interrupted due to a false alarm, causing smoke Oil wastage. At the same time, there are many kinds of heating wires in the existing atomizing heads, and the corresponding properties of heating wires of different materials are also different. If the atomizing head is inserted, it will not work or malfunction.

Each atomizing head is provided with a unique atomizing head label, so that the aerosol generating device can set the initial resistance value according to the atomizing head label. After obtaining the cigarette lighting signal, set the corresponding priority temperature according to the length of the cigarette lighting. There are various priority temperatures, so as to realize multi-level control of the output power of the aerosol generating device from multiple angles, so that the aerosol generating device The output power change is more accurate, avoiding dry burning. There are multiple priority settings in this scheme, taking into account the overall lighting time and the local time after the start of smoking, and flexibly set the corresponding priority resistance according to the priority, fully considering the material of the atomizing head on the priority resistance overall impact, improving the accuracy of prioritization.

The TCR value is obtained according to the material code of the heating wire, which fully considers the possibility of combining the atomizing heads of heating wires of different materials with the current aerosol generating device. That is to say, the aerosol generating device supports atomizing heads of various heating wires. Compared with the atomizing head that can only support one kind of heating wire, the application range of the aerosol generating device is wider. The priority resistance value is calculated according to the material code of the heating wire, the label of the atomizing head, the resistance value of the heating wire, the preset initial temperature and the preset priority temperature, so that the setting of the priority resistance value is more convenient than the direct fixed value. In order to be accurate and fit, correspondingly, according to the cigarette lighting time, the current resistance value of the heating wire and the priority resistance value, the control alarm and output power switching executed are also more accurate.

The implementation details of the control method of the aerosol generating device of this embodiment are described in detail below. The following content is only the implementation details provided for the convenience of understanding, and is not necessary for the implementation of this solution. The specific flow of this embodiment is shown in Figure 1. This embodiment is applied to an aerosol generating device control device.

Step 101, obtain the atomization head number and the current heating wire resistance value of the connected atomization head, and the atomization head number of the atomization head is unique.

Specifically, the atomizing head label ID of the atomizing head is unique to the atomizing head, and this label represents the identity of the atomizing head that is different from other atomizing heads. The current resistance value R _s of the heating wire is obtained by real-time detection to obtain the resistance value of the heating wire in the atomizing head connected to the aerosol generating device; in some examples, a resistance detection circuit is set in the atomizing head to detect the current value of the heating wire The heating wire resistance R _s , and then the current heating wire resistance R _s is transmitted as data to the aerosol generating device control device connected to it through data transmission; in other examples, the aerosol generating device control device is set to resist Value detection circuit, the resistance detection circuit is turned on when the atomization head is inserted into the control device (body) of the aerosol generating device, and the resistance detection circuit detects the current resistance value R _s of the heating wire in the atomizer.

The specific implementation process of step 101 is shown in Fig. 2, including:

S1-1, use the preset decryption method to read the atomization head label in the atomization head connected to the aerosol generating device; if it cannot be read, execute S1-3; if it can be read, execute S1-2 ;

S1-2, compare whether the read atomization head label is consistent with all preset standard atomization head labels, and the standard atomization head label is the label of all atomization heads equipped by the original factory;

When the read atomization head numbers are all inconsistent with all the preset standard atomization head numbers, execute S1-3;

When the number of the atomizing head read is the same as that of all preset standard atomizing head numbers, execute S1-4;

S1-3, stop supplying power to the atomizing head;

S1-4, proceed to the subsequent step 102.

Wherein, the implementation details of step S1-1 are as follows: the ID of the atomizing head in the atomizing head is encrypted and stored, and the corresponding decryption function is set in the control device of the aerosol generating device, and the decryption method of the decryption function is the same as that of the corresponding fog The encryption method of the header is corresponding. That is to say, the control device of the aerosol generating device can read the number of the encrypted atomizing head in the corresponding atomizing head; for example, the decryption method of the control device of the aerosol generating device is a', and the encryption method of the atomizing head is a, when the control device corresponds to the atomizing head, a' corresponds to a, and the control device of the aerosol generating device can read the IDs of the atomizing heads in all the atomizing heads encrypted by the a encryption method. Through step S1-1, a preliminary judgment can be made simply based on whether the decryption method of the aerosol generating device matches the encryption method of the currently connected atomizing head, whether the currently connected atomizing head matches the main body of the aerosol generating device. And step S1-1 can also be expressed as, in Figure 2, read the encrypted IC information and the real-time resistance value of the atomizing head; where the encrypted IC information refers to the atomizing head label ID burned after the atomizing head is encrypted, The real-time resistance value of the atomizing head is the above-mentioned current resistance value R _s of the heating wire.

Among them, the essence of step S1-2 is to judge whether it is an original atomizing head; in this solution, the ID information corresponding to all original atomizing heads is directly stored in the aerosol generating device body, and in step S1-2, the ID information corresponding to the original atomizing head is directly stored. Numerical comparison between the ID of the atomizing head read in step S1-1 and all the standard atomizing head IDs stored; When the labels are inconsistent", it means that the atomizer label ID of the current atomizer head is not one of the standard atomizer head labels stored in the aerosol generator body, that is, the atomizer head of the currently connected aerosol generator body It is not the original atomizing head; "When the read atomizing head numbers are the same as all the preset standard atomizing head numbers", it means that the atomizing head ID of the current atomizing head is gas One of the standard atomizing head numbers stored in the body of the aerosol generating device, that is, the atomizing head of the currently connected aerosol generating device body is one of the original atomizing heads.

Among them, step S1-3 represents that when the ID of the atomizing head of the current atomizing head is not any one of the standard atomizing head numbers corresponding to the original atomizing head of the aerosol generating device, the body of the aerosol generating device Stop supplying power to the pod to realize the function of prohibiting cigarette lighting.

Step 102, setting an initial resistance value according to the atomization head number of the atomization head and the current resistance value of the heating wire.

Specifically, it includes: comparing the atomization head number with the atomization head number in the pre-stored historical data; when the atomization head number is consistent with one of the atomization head numbers in the historical data, the consistent The initial resistance value corresponding to the atomizing head label in the historical data is used as the initial resistance value corresponding to the atomizing head label of this atomizing head; the atomizing head label in the atomizing head label and the atomizing head label in the historical data If they are inconsistent, the current heating wire resistance value is used as the initial resistance value corresponding to the atomizing head label of the atomizing head.

Taking Fig. 3 as an example, step 102 includes:

S2-1, judging whether it is a previously used atomizing head: comparing the number of the atomizing head with the number of the atomizing head in the pre-stored historical data;

If yes: when the atomization head number is consistent with one of the atomization head numbers in the historical data, execute S2-2;

If not: when the number of the atomization head is inconsistent with the number of the atomization head in the historical data, perform step S2-3;

S2-2, use the value stored in the device as the initial value R _I for temperature calculation: the initial resistance value R I corresponding to the atomizing head label in the consistent historical data is used as the initial resistance value R _I connected to the body of the aerosol generating device The initial resistance value R _I corresponding to the ID of the atomizing head of the atomizing head;

S2-3. Set the real-time resistance value as the initial value R _I for temperature calculation: use the current resistance value R _s of the heating wire as the initial resistance value R _I corresponding to the label of the atomizing head of the present atomizing head.

In this solution, according to the ID of the atomizing head, the corresponding initial resistance value R _I is searched from the historical data, and the historical data includes the interrelated atomizing head label and initial resistance value, that is, "ID-R _I "; if If the number of the atomizing head does not exist in the historical data, the current heating wire resistance value R _s is used as the corresponding initial resistance value R _I , and the initial resistance value R _I will not change until the atomizing head is set. The connection to the aerosol generating device control device is disconnected. It should be noted that in step S2-3, the current heating wire resistance value R _s refers to the current heating wire resistance value acquired in step 101 at the moment when the control device of the aerosol generating device is connected to the atomizing head.

In some examples, while performing step S2-3, the ID of the atomizer head and the initial resistance value _RI are updated to historical data, so as to realize automatic updating of historical data.

In some examples, after step 102 is completed, self-calibration of the initial resistance value will also be performed, including:

S2-4, judging whether to light a cigarette: obtain a cigarette lighting operation signal, which includes a cigarette lighting start signal and a cigarette lighting end signal;

If: within the preset self-calibration time period, the cigarette lighting start signal is received, then execute S2-5;

If no: within the preset self-calibration time period, the cigarette lighting start signal is not received, then execute S2-6;

S2-5, interrupting the execution of the self-calibration process, and executing the self-calibration process again when receiving the cigarette lighting end signal;

S2-6, executing a self-calibration process.

In this scheme, the self-calibration process will not hinder the normal judgment and output power adjustment process of the aerosol generating device. The self-calibrating process is to make full use of time and space during the idle time of the aerosol generating device, and through This self-calibration process is used to improve the accuracy of the initial value (initial resistance R _I ).

Step 103, according to the priority temperature, the initial temperature, the initial resistance value and the TCR value corresponding to the material of the atomizing head, the corresponding priority resistance value is obtained.

Specifically, the implementation of step 103 includes the following steps:

S3-1, obtaining the material code of the heating wire in the connected atomizing head;

S3-2. Find the corresponding TCR value from the preset material coefficient association table according to the material code of the heating wire; the material coefficient association table includes the interrelated heating wire material code, heating wire material and TCR value;

S3-3. Calculate the corresponding priority resistance value according to the priority temperature, the initial temperature, the initial resistance value, and the TCR value corresponding to the material of the atomizing head, and the initial temperature T ₀ is preset.

Among them, in step S3-1, the material code of the heating wire of the atomizing head represents the material of the heating wire in the atomizing head, and different materials correspond to different material codes of the heating wire. When the information has been burned and stored, the aerosol generating device control device can read the burned and stored heating wire material code after it is connected to the atomizing head. Therefore, in step S3-1, the heating wire material code in the encrypted IC information in the atomizing head can be read through the same decryption reading device as in step 101.

In S3-2, according to the heating wire material code, the corresponding TCR value is found from the preset material coefficient association table; the material coefficient association table includes the interrelated heating wire material code, heating wire material and TCR value M .

In S3-3, according to the priority temperature, the initial temperature, the initial resistance value and the TCR value corresponding to the material of the atomizing head, the corresponding priority resistance value is obtained. This step is intended to set the temperature points corresponding to multiple priorities for judging dry burning. The priority temperature includes a time-limited priority temperature and a full-time priority temperature T ₁ , and the time-limited priority temperature includes an alarm temperature T ₃ , a power drop temperature T ₂ , and a power recovery temperature T _2s . The implementation of step S3-3 includes:

S3-3-1, according to the TCR value M, the initial resistance value R _I and the preset initial temperature T ₀ , combined with the alarm temperature T ₃ , calculate the corresponding priority resistance value R ₃ ;

S3-3-2, according to the TCR value M, the initial resistance value R _I and the preset initial temperature T ₀ , combined with the power drop temperature T ₂ , calculate the corresponding priority resistance value R ₂ ;

S3-3-3, according to the TCR value M, the initial resistance value R _I and the preset initial temperature T ₀ , combined with the power recovery temperature T _2s , calculate the corresponding priority resistance value R _2s ;

S3-3-4, according to the TCR value M, the initial resistance value R _I and the preset initial temperature T ₀ , combined with the overall priority temperature T ₁ , calculate the corresponding priority resistance value R ₁ .

Step 104, when the cigarette lighting time meets the preset duration condition, judge whether the current heating wire resistance meets the priority resistance value condition according to the preset frequency; Step S105, when the current heating wire resistance value meets the priority resistance value condition When the preset number of times is reached, the operation corresponding to the priority temperature is performed.

Specifically, the duration preset conditions, preset frequencies, priority resistance conditions, and preset times are all associated with the priority temperature, and different priority temperatures correspond to different duration preset conditions and preset frequencies. . Priority resistance conditions and preset times; the corresponding operation of the priority temperature includes at least one of control alarm and output power switching.

That is to say, the execution background of this step 105 is that the duration of lighting a cigarette satisfies the preset condition, and the sampling frequency during execution is the preset frequency, based on the number of times the current heating wire resistance meets the priority resistance condition, and the number of times reaches the preset The number of times is set as the judgment condition, and the execution result is the corresponding operation of the priority temperature.
