[0049] To make the objectives, features, and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the embodiments described below are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0051] It should also be understood that the terms used in the description of the present application herein are for the purpose of describing specific embodiments only and are not intended to limit the present application. As used in the description of the present application and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include the plural forms.

[0052] It should be further understood that the term "and / or" used in the description of the present application and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0053] In addition, in the description of the present application, the terms "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0054] Currently, heat not burning (HNB) appliances usually are provided with a negative temperature coefficient (NTC) temperature sensor for detecting the heating temperature of the heating component of the HNB appliance, and a microphone for detecting whether the HNB appliance is being puffed.

[0055] However, both the NTC temperature sensor and the microphone need to separately occupy the chip pins of the control chip of the HNB appliance, increasing the design cost of the control chip and resulting in an increase in the manufacturing cost of the HNB appliance.

[0056] In view of the above problems, the heat not burning appliance, the puff number counting method thereof and the storage medium provided by the embodiments of the present application, when it is determined that the heat not burning appliance has completed preheating, record a plurality of airflow temperatures of the heat not burning appliance collected by the negative temperature coefficient temperature sensor according to a preset rule to obtain an airflow temperature array, and determine whether the heat not burning appliance is being puffed according to the airflow temperature array, and when it is determined according to the airflow temperature array that the heat not burning appliance is being puffed, increment the puff number of the heat not burning appliance by one, realizing puff detection of the heat not burning appliance based on the airflow temperature collected by the negative temperature coefficient temperature sensor, and incrementing the puff number of the heat not burning appliance when it is detected that the heat not burning appliance is being puffed. During the counting process of the puff number of the heat not burning appliance, the negative temperature coefficient temperature sensor is used to replace the microphone to perform puff detection on the heat not burning appliance. The negative temperature coefficient temperature sensor for collecting the airflow temperature can share the chip pins with the negative temperature coefficient temperature sensor for collecting the heating temperature, reducing the chip pins occupied by the microphone, reducing the design cost of the control chip, and being beneficial to reducing the manufacturing cost of the heat not burning appliance.

[0057] Moreover, the microphone has poor high-temperature resistance and ages relatively fast in heated non-combustible appliances. Replacing the microphone with a negative temperature coefficient temperature sensor can inhibit the decrease in detection accuracy of the suction detection of heated non-combustible appliances caused by the aging of the microphone, which is beneficial to improving the detection accuracy of the suction detection of heated non-combustible appliances.

[0058] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application.

[0059] Please refer to Figure 1 , which shows a schematic diagram of an application scenario of the HNB appliance 100 provided in the embodiment of the present application. The HNB appliance 100 may include a housing 101, a heating component 102, an NTC temperature sensor 103, and a control chip 104. The heating component 102, the NTC temperature sensor 103, and the control chip 104 may be installed in the housing 101, and the housing 101 may provide installation support for the heating component 102, the NTC temperature sensor 103, and the control chip 104.

[0060] Among them, the housing 101 may be provided with a medium cavity for storing the atomization medium. The atomization medium is used to generate aerosol after heating. The main components of the atomization medium may include glycerol, propylene glycol, flavor, nicotine, etc., which are not limited herein.

[0061] The material of the housing 101 may be any one of engineering plastics (for example, polycarbonate (PC), polystyrene (PS), polyamide (PA), polyimide (PI), etc.), aluminum alloy, stainless steel, or ABS plastic (Acrylonitrile Butadiene Styrene Plastic, ABS plastic), etc., which are not limited herein.

[0062] The heating component 102 may be used to heat the atomization medium stored in the medium cavity to generate aerosol. The heating component 102 may be any one of a resistance heating element, an electromagnetic heating element, an infrared heating element, etc., which are not limited herein.

[0063] The NTC temperature sensor 103 may be used to collect the temperature parameters of the HNB appliance 100. The number of NTC temperature sensors 103 may be one or more. The temperature parameters may include heating temperature and / or air flow temperature, etc., which are not limited herein.

[0064] The control chip 104 can be communicatively connected to the heating component 102 and the NTC temperature sensor 103, and the control chip 104 can be used to control the heating component 102 and the NTC temperature sensor 103 to work.

[0065] The control chip 104 can be any one of a micro control unit (MCU), a central processing unit (CPU), a combinatorial logic controller (CLC), a complex programmable logic device (CPLD), or a field programmable gate array (FPGA), etc., which is not limited herein.

[0066] In some embodiments, the housing 101 can further be provided with an air flow channel, and the air flow channel communicates with the medium cavity and the external space of the HNB appliance 100.

[0067] The number of NTC temperature sensors 103 can be two. The NTC temperature sensors 103 can include a first NTC temperature sensor and a second NTC temperature sensor, and the temperature parameters can include the heating temperature and the air flow temperature.

[0068] The first NTC temperature sensor can be installed relative to the heating component 102 and is used to collect the heating temperature of the heating component 102. The second NTC temperature sensor can be disposed in the air flow channel and is used to collect the air flow temperature in the air flow channel.

[0069] In some embodiments, the number of NTC temperature sensors 103 can be one. The NTC temperature sensor 103 can be installed relative to the heating component 102 and is used to collect the heating temperature of the heating component 102.

[0070] At the same time, the air flow channel is rerouted so that the NTC temperature sensor 103 is in the air flow channel. The NTC temperature sensor 103 can be used to collect the air flow temperature in the air flow channel. Through the rerouting design of the air flow channel, the NTC temperature sensor 103 can be used to collect the heating temperature of the heating component 102 and the air flow temperature in the air flow channel, reducing the design quantity of the NTC temperature sensors 103, which is beneficial to further reducing the manufacturing cost of the HNB appliance 100.

[0071] Please refer to Figure 2, which shows a flowchart of a method for counting the number of puffs of a heat-not-burn appliance provided in an embodiment of the present application. In a specific embodiment, the method for counting the number of puffs of a heat-not-burn appliance can be applied to a control chip 104 in an HNB appliance 100 as shown in Figure 1 The following will take the control chip 104 as an example to elaborate in detail on the Figure 2 The process shown. The method for counting the number of puffs of a heat-not-burn appliance may include the following steps 210 to step 230.

[0072] Step 210: When it is determined that the heat-not-burn appliance has completed preheating, record multiple airflow temperatures of the heat-not-burn appliance collected by a negative temperature coefficient temperature sensor according to a preset rule to obtain an airflow temperature array.

[0073] In an embodiment of the present application, when the control chip determines that the HNB appliance has completed preheating, it can record multiple airflow temperatures of the HNB appliance collected by the NTC temperature sensor according to a preset rule to obtain an airflow temperature array.

[0074] Among them, the multiple airflow temperatures can be obtained by the NTC temperature sensor collecting the temperature of the airflow channel of the HNB appliance at preset time intervals, and each airflow temperature corresponds to a temperature collection moment.

[0075] The preset time interval can be a time interval preset by the user, or a time interval automatically generated by the control chip according to the counting process of counting the number of puffs of the HNB appliance multiple times, etc., which is not limited here.

[0076] As an example, the preset time interval can be 0.1 second (s), the preset time interval can also be 0.05 s, and the preset time interval can also be 0.2 s, etc., which is not limited here.

[0077] The preset rule can be used to represent a selection rule for selecting a preset number of airflow temperatures from multiple airflow temperatures in the order from the nearest to the farthest temperature collection moment.

[0078] The preset number can be a number preset by the user, or a number automatically generated by the control chip according to the counting process of counting the number of puffs of the HNB appliance multiple times, etc., which is not limited here.

[0079] As an example, the preset number can be 20, the preset number can also be 30, and the preset number can also be 10, etc., which is not limited here.

[0080] Specifically, when the control chip determines that the HNB appliance has completed preheating, it can send a first acquisition instruction to the NTC temperature sensor. The NTC temperature sensor receives and responds to the first acquisition instruction, collects the temperature of the air flow channel of the HNB appliance at a preset time interval, obtains a plurality of air flow temperatures, and selects a preset number of air flow temperatures from the plurality of air flow temperatures in the order from the nearest to the farthest temperature acquisition time of the plurality of air flow temperatures, records them as an air flow temperature array. Selecting a preset number of air flow temperatures in the order from the nearest to the farthest acquisition time to obtain the air flow temperature array makes the air flow temperatures included in the air flow temperature array be real-time air flow temperatures, which is beneficial to improving the detection accuracy of detecting the suction state of the HNB appliance according to the air flow temperature array.

[0081] Among them, the suction state may include the suction state and the non-suction state, etc., which are not limited here.

[0082] As an example, the preset time interval is 0.1 s and the preset number is 20. The NTC temperature sensor can collect the air flow temperature in the air flow channel of the HNB appliance every 0.1 s, record the collected air flow temperatures into the air flow temperature array in sequence, and after recording 20 air flow temperatures, cover and update the air flow temperature corresponding to the earliest temperature acquisition time in the air flow temperature array with the newly collected air flow temperature.

[0083] Step 220: Determine whether the heat-not-burn appliance is being suctioned according to the air flow temperature array.

[0084] In the embodiment of the present application, when the control chip determines that the HNB appliance has completed preheating, after recording the multiple air flow temperatures of the HNB appliance collected by the NTC temperature sensor according to a preset rule to obtain the air flow temperature array, it can determine whether the HNB appliance is being suctioned according to the air flow temperature array.

[0085] Specifically, when the control chip determines that the HNB appliance has completed preheating, after recording the multiple air flow temperatures of the HNB appliance collected by the NTC temperature sensor according to a preset rule to obtain the air flow temperature array, it can calculate the first air flow temperature drop value within the first preset duration according to the air flow temperature array, and determine whether the HNB appliance is being suctioned according to the first air flow temperature drop value. During the suction process of the HNB appliance, the air flow temperature gradually decreases. Detecting the suction state of the HNB appliance according to the first air flow temperature drop value is beneficial to improving the detection accuracy of detecting the suction state of the HNB appliance.

[0086] Among them, the control chip can calculate the first temperature difference between any two air flow temperatures within the first preset duration, and determine the maximum first temperature difference as the first air flow temperature drop value.

[0087] The first preset duration can be a duration preset by the user in advance, or can be a duration automatically generated by the control chip according to the counting process of counting the number of suction times of the HNB device multiple times, etc., which is not limited here.

[0088] When the control chip determines that the first airflow temperature drop value is greater than or equal to the first temperature drop threshold, it can be determined that the HNB device is being suctioned. The first temperature drop threshold can be used to characterize the minimum temperature drop of the airflow temperature within the first preset duration when the HNB device is being suctioned.

[0089] In some embodiments, when the control chip determines that the first airflow temperature drop value is less than the first temperature drop threshold, it can calculate the second airflow temperature drop value within the second preset duration and determine whether the HNB device is being suctioned according to the second airflow temperature drop value. The rate of temperature drop of the airflow during the suction process of the HNB device is not linear. Detecting the suction state of the HNB device according to the second airflow temperature drop value is beneficial to further improve the detection accuracy of the suction state of the HNB device.

[0090] Among them, the control chip can calculate the second temperature difference between any two airflow temperatures within the second preset duration and determine the maximum second temperature difference as the second airflow temperature drop value.

[0091] The second preset duration is greater than the first preset duration. The second preset duration can be a duration preset by the user in advance, or can be a duration automatically generated by the control chip according to the counting process of counting the number of suction times of the HNB device multiple times, etc., which is not limited here.

[0092] When the control chip determines that the second airflow temperature drop value is greater than or equal to the second temperature drop threshold, it can be determined that the HNB device is being suctioned. The second temperature drop threshold is greater than the first temperature drop threshold. The second temperature drop threshold can be used to characterize the minimum temperature drop of the airflow temperature within the second preset duration when the HNB device is being suctioned.

[0093] In some embodiments, when the control chip determines that the second airflow temperature drop value is less than the second temperature drop threshold, it can calculate the third airflow temperature drop value within the third preset duration and determine whether the HNB device is being suctioned according to the third airflow temperature drop value. The rate of temperature drop of the airflow during the suction process of the HNB device is not linear. Detecting the suction state of the HNB device according to the third airflow temperature drop value is beneficial to further improve the detection accuracy of the suction state of the HNB device.

[0094] Among them, the control chip can calculate the third temperature difference between any two airflow temperatures within the third preset duration and determine the maximum third temperature difference as the third airflow temperature drop value.

[0095] The third preset duration is greater than the second preset duration. The third preset duration can be a duration preset by the user in advance, or a duration automatically generated by the control chip according to the counting process of counting the number of suction times of the HNB device multiple times, etc., which is not limited here.

[0096] When the control chip determines that the third airflow temperature decrease value is greater than or equal to the third temperature decrease threshold, it can be determined that the HNB device is being suctioned; when the control chip determines that the third airflow temperature decrease value is less than the third temperature decrease threshold, it is determined that the HNB device is not being suctioned.

[0097] The third temperature decrease threshold is greater than the second temperature decrease threshold. The third temperature decrease threshold can be used to represent the minimum temperature decrease of the airflow temperature within the third preset duration when the HNB device is being suctioned.

[0098] In an application scenario, the first preset duration can be 0.5 s, the first temperature decrease threshold can be 7 degrees Celsius (°C), the second preset duration can be 1 s, the second temperature decrease threshold can be 7 + x °C, the third preset duration can be 2 s, and the third temperature decrease threshold can be 7 + 3x °C.

[0099] When the first airflow temperature decrease value within the first preset duration of 0.5 s is greater than or equal to 7 °C, it is determined that the HNB device is being suctioned. When the first airflow temperature decrease value within the first preset duration of 0.5 s is less than 7 °C and the second airflow temperature decrease value within the second preset duration of 1 s is greater than or equal to 7 + x °C, it is determined that the HNB device is being suctioned. When the second airflow temperature decrease value within the second preset duration of 1 s is less than 7 + x °C and the third airflow temperature decrease value within the third preset duration of 2 s is greater than or equal to 7 + 3x °C, it is determined that the HNB device is being suctioned; when the second airflow temperature decrease value within the second preset duration of 1 s is less than 7 + x °C and the third airflow temperature decrease value within the third preset duration of 2 s is less than 7 + 3x °C, it is determined that the HNB device is not being suctioned.

[0100] Step 230: When it is determined that the heat-not-burn device is being suctioned according to the airflow temperature array, increment the suction count of the heat-not-burn device by one.

[0101] In an embodiment of the present application, when the control chip determines that the HNB device is being puffed based on the airflow temperature array, the puff count of the HNB device can be incremented once. This realizes the puff detection of the HNB device based on the airflow temperature collected by the NTC temperature sensor, and when it is detected that the HNB device is being puffed, the puff count of the HNB device is incremented. During the counting process of the puff count of the HNB device, the NTC temperature sensor is used to replace the microphone to perform the puff detection of the HNB device. The NTC temperature sensor for collecting the airflow temperature can share the chip pins with the NTC temperature sensor for collecting the heating temperature, reducing the chip pins occupied by the microphone, reducing the design cost of the control chip, and facilitating the reduction of the manufacturing cost of the HNB device.

[0102] Moreover, the high-temperature resistance performance of the microphone is poor, and the aging speed of the microphone in the HNB device is relatively fast. Using the NTC temperature sensor to replace the microphone can prevent the detection accuracy of the puff detection of the HNB device from being low due to the aging of the microphone, which is conducive to improving the detection accuracy of the puff detection of the HNB device.

[0103] In some embodiments, when the control chip determines that the HNB device is not being puffed based on the airflow temperature array, it can return to execute step 220 and subsequent steps, realizing continuous puff detection of the HNB device and improving the user experience during the puff detection of the HNB device.

[0104] The solution provided by the present application, when it is determined that the heat-not-burn device has completed preheating, records multiple airflow temperatures of the heat-not-burn device collected by the negative temperature coefficient temperature sensor according to a preset rule to obtain an airflow temperature array, and determines whether the heat-not-burn device is being puffed based on the airflow temperature array. When it is determined that the heat-not-burn device is being puffed based on the airflow temperature array, the puff count of the heat-not-burn device is incremented once. This realizes the puff detection of the heat-not-burn device based on the airflow temperature collected by the negative temperature coefficient temperature sensor, and when it is detected that the heat-not-burn device is being puffed, the puff count of the heat-not-burn device is incremented. During the counting process of the puff count of the heat-not-burn device, the negative temperature coefficient temperature sensor is used to replace the microphone to perform the puff detection of the heat-not-burn device. The negative temperature coefficient temperature sensor for collecting the airflow temperature can share the chip pins with the negative temperature coefficient temperature sensor for collecting the heating temperature, reducing the chip pins occupied by the microphone, reducing the design cost of the control chip, and facilitating the reduction of the manufacturing cost of the heat-not-burn device.

[0105] Moreover, the microphone has poor high-temperature resistance, and the aging rate of the microphone in a heat-not-burn device is relatively fast. Using a negative temperature coefficient temperature sensor to replace the microphone can inhibit the low detection accuracy of the heat-not-burn device during suction detection caused by aging, which is beneficial to improving the detection accuracy of the heat-not-burn device during suction detection.

[0117] When the preheating temperature is greater than or equal to the temperature threshold, it is determined that the HNB device has completed preheating; when the preheating temperature is less than the temperature threshold, it is determined that the HNB device has not completed preheating.

[0124] Please refer to Figure 4 , which shows a flowchart of a method for counting the puff count of a heat-not-burn appliance provided in another embodiment of the present application. In a specific embodiment, the method for counting the puff count of a heat-not-burn appliance can be applied to a control chip 104 in an HNB appliance 100 as shown in Figure 1 . Taking the control chip 104 as an example, the process shown in Figure 4 will be elaborated in detail below.

[0125] Step 410: In response to the received wake-up signal, control the heat-not-burn appliance to switch from the sleep state to the working state.

[0126] In this embodiment, the control chip may control the HNB appliance to switch from the sleep state to the working state in response to the received wake-up signal.

[0127] Among them, the wake-up signal can be used to indicate the HNB appliance to switch from the sleep state to the working state. The wake-up signal may include any one of a voice wake-up signal, a button wake-up signal, or a fingerprint wake-up signal, etc., which is not limited here.

[0128] The sleep state can be used to characterize that the HNB appliance is in a low-power standby state, and the HNB appliance in the sleep state resumes to the working state immediately when receiving a wake-up instruction.

[0129] Step 420: Control the heat-not-burn appliance to perform preheating.

The heating component receives and responds to the first control instruction to preheat the HNB appliance, realizing the preheating of the HNB appliance based on the received wake-up signal, so that the HNB appliance preheats only when it needs to be used, which can reduce the power consumption of the HNB appliance and is conducive to improving the energy efficiency utilization rate of the HNB appliance.

[0131] Step 430: Collect the preheating parameters of the heated non-combustible appliance.

[0132] Step 440: Determine whether the heated non-combustible appliance has completed preheating according to the preheating parameters.

[0133] Step 450: When it is determined according to the preheating parameters that the heated non-combustible appliance has completed preheating, record multiple airflow temperatures of the heated non-combustible appliance collected by the negative temperature coefficient temperature sensor according to a preset rule to obtain an airflow temperature array.

[0134] Step 460: Determine whether the heated non-combustible appliance is being puffed according to the airflow temperature array.

[0135] Step 470: When it is determined according to the airflow temperature array that the heated non-combustible appliance is being puffed, increment the puff count of the heated non-combustible appliance by one.

[0138] Please refer to Figure 5, which shows a flowchart of a method for counting the number of puffs of a heat-not-burn appliance provided by another embodiment of the present application. In a specific embodiment, the method for counting the number of puffs of a heat-not-burn appliance can be applied to a control chip 104 in an HNB appliance 100 as shown in Figure 1 . Taking the control chip 104 as an example, the process shown in Figure 5 will be elaborated in detail below. The method for counting the number of puffs of a heat-not-burn appliance may include the following steps 510 to step 540.

[0139] Step 510: When it is determined that the heat-not-burn appliance has completed preheating, record multiple airflow temperatures of the heat-not-burn appliance collected by a negative temperature coefficient temperature sensor according to a preset rule to obtain an airflow temperature array.

[0140] Step 520: Determine whether the heat-not-burn appliance is puffed according to the airflow temperature array.

[0141] Step 530: When it is determined according to the airflow temperature array that the heat-not-burn appliance is puffed, increment the number of puffs of the heat-not-burn appliance by one.

[0142] In this embodiment, steps 510, 520, and 530 may refer to the content of the corresponding steps in the foregoing embodiments, and will not be elaborated here.

[0143] Step 540: Clear the airflow temperature array.

[0144] In this embodiment, when the control chip determines that the HNB appliance is puffed according to the airflow temperature array, after incrementing the number of puffs of the HNB appliance by one, the airflow temperature array can be cleared, realizing that after counting the number of puffs of each puff of the HNB appliance, the airflow temperature array is cleared in time, which can reduce resource occupation and is beneficial to improving the operation efficiency of the HNB appliance.

[0145] In some embodiments, after the control chip clears the airflow temperature array, when the number of puffs is less than the puff number threshold and the HNB appliance meets the preset conditions, it can return to execute the step of recording multiple airflow temperatures of the HNB appliance collected by the NTC temperature sensor according to the preset rule to obtain an airflow temperature array and subsequent steps, realizing continuous counting of the number of puffs of the HNB appliance, which is beneficial to improving the user experience during the counting process of counting the number of puffs of the HNB appliance.

[0146] Among them, the puff number threshold can be used to represent the maximum number of puffs of the atomization medium in the HNB appliance. The puff number threshold can be the number of puffs preset by the user, or the number of puffs automatically generated by the control chip according to the counting process of counting the number of puffs of the HNB appliance multiple times, etc., which is not limited here.

[0147] The condition that the HNB device meets the preset condition can be: the waiting duration after clearing the air flow temperature array is greater than or equal to the waiting duration threshold.

[0148] The waiting duration threshold can be used to represent the maximum continuous duration for a user to take a puff of the HNB device. The waiting duration threshold can be a continuously duration preset by the user, or a continuously duration automatically generated by the control chip according to the counting process of counting the number of puffs of the HNB device multiple times, etc., which is not limited here.

[0149] As an example, the waiting duration threshold can be 2s, or the waiting duration threshold can be 3s, or the waiting duration threshold can also be 1.5s, etc., which is not limited here.

[0150] In some embodiments, after the control chip clears the air flow temperature array, when the number of puffs is greater than or equal to the puff number threshold, the control HNB device stops heating. When the atomization medium in the HNB device is puffed again after reaching the maximum number of puffs, the atomization medium releases harmful substances to the human body. When it is detected that the atomization medium has reached the maximum number of puffs, the HNB device is forced to stop heating the atomization medium, which can reduce the user's inhalation of harmful substances and is beneficial to reducing the health risk of the user puffing the HNB device.

[0151] In an application scenario, as Figure 6 shown, the puff number counting method of the heat-not-burn device may include the following steps 601 to step 611.

[0152] Step 601: In response to the received wake-up signal, control the heat-not-burn device to switch from the sleep state to the working state.

[0153] Step 602: Control the heat-not-burn device to perform preheating.

[0154] Step 603: Collect the preheating parameters of the heat-not-burn device.

[0155] Step 604: Determine whether the heat-not-burn device has completed preheating according to the preheating parameters.

[0156] When it is determined according to the preheating parameters that the HNB device has completed preheating, execute step 605;

[0157] When it is determined according to the preheating parameters that the HNB device has not completed preheating, return to execute step 602.

[0158] Step 605: Record the multiple air flow temperatures of the heat-not-burn device collected by the negative temperature coefficient temperature sensor according to a preset rule to obtain an air flow temperature array.

[0159] Step 606: Determine whether the heat-not-burn device is being puffed according to the air flow temperature array.

[0160] When it is determined according to the air flow temperature array that the HNB device is being puffed, step 607 is executed;

[0161] When it is determined according to the air flow temperature array that the HNB device is not being puffed, return to execute step 605.

[0162] Step 607: Increment the puff count of the heat-not-burn device by one.

[0163] Step 608: Clear the air flow temperature array.

[0164] Step 609: Determine whether the puff count is less than the puff count threshold.

[0165] When it is determined that the puff count is less than the puff count threshold, step 610 is executed;

[0166] When it is determined that the puff count is greater than or equal to the puff count threshold, step 611 is executed.

[0167] Step 610: Wait for the HNB device to meet the preset conditions, and return to execute step 605.

[0168] Step 611: Control the HNB device to stop heating.

[0169] In the solution provided in this embodiment, when it is determined according to the preheating parameters that the heat-not-burn device has completed preheating, multiple air flow temperatures of the heat-not-burn device collected by the negative temperature coefficient temperature sensor are recorded according to a preset rule to obtain an air flow temperature array, and it is determined whether the heat-not-burn device is being puffed according to the air flow temperature array. When it is determined according to the air flow temperature array that the heat-not-burn device is being puffed, the puff count of the heat-not-burn device is incremented by one, and the air flow temperature array is cleared, realizing that after counting the puff count of each puff of the heat-not-burn device, the air flow temperature array is promptly cleared, which can reduce resource occupation and is beneficial to improving the operation efficiency of the heat-not-burn device.
