This is to avoid the core portion of the present application being overwhelmed by excessive descriptions, and for those skilled in the art, it is not necessary to describe these related operations in detail. They will fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0034] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0035] Component numbers used herein, such as "first" and "second," are used solely to distinguish the components being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0036] In this solution, in order to solve the problem that when existing smoking devices heat cigarettes, the taste of the cigarettes before and after smoking is easily different, a temperature control method for smoking devices is proposed. The specific solution is as follows.

[0037] As shown in FIG1 , this embodiment provides a temperature control method for a smoking device, comprising:

[0038] Step 100: After the smoking device starts heating, the heating module 10 heats the cigarette using a preset first temperature curve.

[0039] Before use, a control curve of the temperature and time relationship of the smoking device is preset, that is, a preset first temperature curve and a preset second temperature curve. Then, after the smoking device starts heating, the preset first temperature curve is used to heat the cigarette.

[0040] Step 200: The determination processing module 20 determines whether the cigarette has been puffed. If so, step 300 is executed: the cigarette is heated using a preset second temperature curve for a first preset time, and then heated using the preset first temperature curve. Otherwise, step 400 is executed: the cigarette is heated using the preset first temperature curve again. The temperature of the preset second temperature curve at the same time is higher than that of the preset first temperature curve. Specifically, the preset second temperature curve in this embodiment is obtained by raising the preset temperature of the preset first temperature curve by a certain preset amount. This ensures that the consistency of the taste of the puffs is enhanced without changing the original heating method.

[0041] As shown in the temperature control curve diagram in 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. A peak will appear in the actual heating curve, and the heating element is ensured to heat 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 is completed, thereby ensuring the taste of the next puff. If no puffing action is detected, the heating element can be heated with the preset first temperature curve.

[0042] 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, at this time triggering the preset second temperature curve, and controlling the heating element to use the preset second temperature curve to heat the cigarette.

[0043] In actual use, after the smoking device starts heating, when no puff is detected, the heating element is controlled to first heat the cigarette using a preset first temperature curve. When a puff is detected, the cigarette is heated using a preset second temperature curve. After a certain period of time at the preset second temperature curve, the cigarette is heated again using the preset first temperature curve. This cycle continues until the 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 solution, when puff is detected, the temperature is increased, which is more conducive to smoke output. The high temperature is maintained for a period of time to produce a certain amount of smoke. When the temperature returns to the original curve, the smoke can be kept from condensing, preparing for the next puff. In addition, by adjusting the temperature curve according to the puffing process, the consistency of the puff taste can be enhanced.

[0044] In one feasible embodiment, 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 has occurred; otherwise, no puffing action has occurred.

[0045] Specifically, in this embodiment, an air duct is provided below the heating element. When a puff is taken, air will flow through the air duct. An airflow sensor is provided in the air duct of the smoking device to detect whether air is flowing through the air duct. When airflow is detected, and the duration of the airflow is greater than or equal to a second preset time, it is confirmed that a puff has occurred. When the airflow sensor does not detect airflow, or detects airflow but the duration is very short, it is considered that no puff has occurred. The airflow sensor then transmits the detected signal to the controller, which controls the temperature curve corresponding to the selected area of ​​the heating element to heat the cigarette.

[0046] In one feasible embodiment, after heating the cigarette using 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.

[0047] 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.

[0048] In another achievable embodiment, the first preset time includes a puff duration period and a first time period; after heating the cigarette for the first preset time using a preset second temperature curve, heating is then performed using the preset first temperature curve, including: starting from the detection of the puffing action, heating the cigarette using the preset second temperature curve until the end of the puffing action, then continuing to heat the cigarette for the first time period using the preset second temperature curve, and then heating again using the preset first temperature curve; the first time period gradually decreases according to a preset rule as the number of puffs increases.

[0049] This embodiment provides another high-temperature heating method. Specifically, upon detecting a puff, the controller controls the heating element to heat the cigarette using a preset second temperature curve. Heating continues using the preset second temperature curve until the puff is complete, and then continues heating using the preset second temperature curve for a period of time (i.e., the first period of time). This first period of time can gradually decrease in length according to a preset pattern as the number of puffs increases. For example, if the puff takes 2 seconds and the continuous heating time is 3 seconds, the high-temperature time for this puff is 5 seconds; the next puff takes 4 seconds and the continuous heating time is 2 seconds, the high-temperature time for this puff is 6 seconds, and so on. Alternatively, the first period of time can be set to a fixed value. For example, regardless of the number of seconds the puff takes, heating continues using the preset second temperature curve for 2 seconds after the puff ends. Thereafter, heating continues using the preset first temperature curve, and this pattern repeats until the current cigarette is used up.

[0050] In one feasible embodiment, the method further includes: accumulating the number of puffs, determining whether the number of puffs reaches a preset value, and if so, stopping heating.

[0051] 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.

[0052] As shown in Figure 3, this embodiment provides a temperature control system for a smoking device, comprising a heating module 10 and a determination and processing module 20. The heating module 10 is configured to heat the cigarette using a preset first temperature curve after the smoking device starts heating. The determination and processing module 20 is configured to determine whether the cigarette has been puffed. If so, the cigarette is heated using a preset second temperature curve for a preset time, and then heated using the preset first temperature curve again. Otherwise, the cigarette is heated using the preset first temperature curve. The temperature of the preset second temperature curve at the same time is higher than that of the preset first temperature curve.
