Background Art

At present, the existing smoking utensils have relatively monotonous temperature control methods for cigarettes. Under normal circumstances, they either use a temperature curve for direct control.

Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

In this solution, in order to solve the problem that when existing smoking utensils heat cigarettes, the taste difference between the front and back puffs during the smoking process is easily caused, a temperature control method of the smoking utensil is proposed, and the specific solution is as follows.

As shown in FIG1 , the present embodiment provides a method for controlling the temperature of a smoking device, comprising:

Step 100: After the smoking device starts heating, the heating module 10 heats the cigarette using a preset first temperature curve.

Before use, a control curve of the temperature and time relationship of the smoking device is preset, that is, a first temperature curve and a second temperature curve are preset. Then, after the smoking device starts heating, the preset first temperature curve is used to heat the cigarette.

Step 200: Determine whether the cigarette has been puffed by the judgment processing module 20. If so, execute step 300: heat the cigarette for a first preset time using the preset second temperature curve, and then heat it using the preset first temperature curve; otherwise, execute step 400: continue to heat the cigarette using the preset first temperature curve; wherein the temperature of the preset second temperature curve at the same time is higher than the temperature of the preset first temperature curve. Specifically, the preset second temperature curve in this embodiment is obtained by raising a certain preset temperature on the basis of the preset first temperature curve, so that the consistency of the taste of the puffs before and after can be enhanced without changing the original basic heating method.

As shown in the temperature control curve diagram of Figure 2, the upper and lower curves are respectively the preset second temperature curve and the preset first temperature curve, and the curve between the preset second temperature curve and the preset first temperature curve is the actual heating curve. When the puffing action is not detected, the heating element is controlled to heat with the preset first temperature curve. When the puffing action is detected, the actual heating temperature at the current moment rises from the preset first temperature curve to the preset second temperature curve. The actual heating curve will have a peak value, and ensure that the heating element heats the cigarette with the preset second temperature curve for the first preset time, and then heats the cigarette with the preset first temperature curve to ensure that the cigarette can still produce sufficient smoke after the current puffing action ends, thereby ensuring the taste of the next puff. If the puffing action is not detected, the heating element can be heated with the preset first temperature curve.

In addition, in actual application, after starting the heating, the cigarette needs to be preheated. After the preheating is completed, the preset first temperature curve is used to prevent condensation temperature operation and heat the cigarette. Then, the airflow sensor inside the smoking device detects the puffing action. When the puffing action occurs, the airflow sensor will have airflow passing through, which triggers the preset second temperature curve and controls the heating element to heat the cigarette using the preset second temperature curve.

In actual application, after the smoking device starts heating, when no puffing is detected, the heating element is controlled to first heat the cigarette using the preset first temperature curve. When a puffing action is detected, the preset second temperature curve is used to heat the cigarette. After a certain period of time under the preset second temperature curve, the preset first temperature curve is returned to heat the cigarette again, and this cycle is repeated until a cigarette is completely puffed, wherein at the same time, the temperature of the preset second temperature curve is higher than the preset first temperature curve. By adopting the smoking device temperature control method/system of this scheme, when puffing is detected, the temperature is increased, which is more conducive to the amount of smoke output, and the high temperature is continued for a period of time to bake out a certain amount of smoke. When the temperature returns to the original curve again, the smoke can be kept from condensing, preparing for the next puffing. In addition, the temperature curve is adjusted according to the puffing process, which can also enhance the consistency of the puffing taste.

In an achievable implementation, determining whether a puffing action occurs includes: detecting whether there is airflow passing through the airway of the smoking device through an airflow sensor; if so, and the duration is greater than or equal to a second preset time, determining that a puffing action occurs; otherwise, no puffing action occurs.

Specifically, in this embodiment, an airway is provided below the heating element. When a puffing action occurs, airflow will pass through the airway. An airflow sensor is provided in the airway of the smoking device to detect whether airflow passes through the airway. When airflow is detected, and the duration of the airflow is greater than or equal to the second preset time, it is proved that a puffing action has occurred. When the airflow sensor does not detect airflow, or detects airflow but the duration is very short, it is considered that no puffing action has occurred. The airflow sensor then transmits the detected signal to the controller, and the controller controls the temperature curve corresponding to the selected area of the heating element to heat the cigarette.

In an achievable embodiment, after heating the cigarette with a preset second temperature curve for a first preset time, the preset first temperature curve is used for heating, including: starting from the time when the puffing action is detected, the preset second temperature curve is used to heat the cigarette for a fixed first preset time, and then the preset first temperature curve is used for heating.

In this embodiment, specifically, when a puffing action is detected, the controller controls the heating element to heat the cigarette using a preset second temperature curve, and pre-sets the heating time using the preset second temperature curve. For example, after detecting a puffing start signal, the controller jumps to the high temperature curve and continues for 5 seconds before heating the cigarette using the preset first temperature curve.

In another achievable embodiment, the first preset time includes a puff duration period and a first time period; after the cigarette is heated for the first preset time using a preset second temperature curve, it is then heated using a preset first temperature curve, including: starting from the detection of the puff action, the cigarette is heated using the preset second temperature curve until the end of the puff action, and then the preset second temperature curve is used to continue heating for the first time period, and then the preset first temperature curve is used for heating again; the first time period gradually decreases according to a preset rule as the number of puffs increases.

This embodiment is another high-temperature heating method. Specifically, when the puffing action is detected, the controller controls the heating element to heat the cigarette using the preset second temperature curve, and uses the preset second temperature curve to heat until the puffing action ends, and then continues to use the preset second temperature curve to heat for a period of time (that is, the first period of time). For the first period of time, as the number of puffs increases, the duration gradually decreases according to the preset rule. For example, assuming that the puffing time is 2s and the continuous heating time is 3s, the high-temperature time of this puff is 5s; the next puffing time is 4 seconds, and the continuous heating time is 2s, then the high-temperature time of this puff is 6s, and so on. The first period of time can also be set to a fixed value. For example, no matter how many seconds the puffing action takes, after the puffing action ends, the preset second temperature curve is used to heat for 2 seconds. Afterwards, the preset first temperature curve is used for heating, and this rule is repeated until the current cigarette is used up.

In an achievable implementation, the method further includes: accumulating the number of puffs, determining whether the number of puffs reaches a preset value, and if so, stopping heating.

In this embodiment, the smoking device also has a counting module. During the puffing process, the counting module can accumulate the number of puffing actions and send the accumulated result to the controller in real time. The controller can compare the accumulated result with the preset value. When the accumulated result reaches the preset value, the controller controls the heating element to stop heating. When the preset value is not reached, heating continues.

The heating module 10 is used to heat the cigarette using a preset first temperature curve after the smoking device starts heating; the judgment processing module 20 is used to judge whether the cigarette has a puffing action, and if so, the preset second temperature curve is used to heat the cigarette for a first preset time, and then the preset first temperature curve is used to heat it; otherwise, the preset first temperature curve is continued to be used to heat the cigarette; wherein the temperature of the preset second temperature curve at the same time is higher than the temperature of the preset first temperature curve.
