Description

Heat not burning aerosol generating device and energy supply method thereof TECHNICAL FIELD

[0001] The present application relates to the technical field of heat not burning aerosol generating devices, in particular to a heat not burning aerosol generating device and an energy supply method thereof. BACKGROUND

[0002] The working principle of a heat not burning (HNB) aerosol generating device is to generate aerosol by heating an aerosol generating substrate. The heat not burning aerosol generating device mainly includes an aerosol generating substrate part, a heating part, a temperature feedback part, and a charging part. When the heat not burning aerosol generating device is working, the heating power output by the heating part is usually controlled by a specific algorithm according to the difference between the substrate temperature fed back by the temperature sensor and the target temperature set, so as to control the heating temperature in the range of 200-350 degrees, so that the aerosol generating substrate is just heated to a sufficient degree to emit a specific flavor. However, when the aerosol generating substrate is first inserted into the heat not burning aerosol generating device, the temperature sensor cannot accurately measure the substrate temperature at the beginning because it takes a certain time for energy to be transmitted from the heating part to the aerosol generating substrate. Therefore, the measured substrate temperature has a certain hysteresis, so the power is output according to time at the beginning, which leads to the fact that when multiple aerosol generating substrates are continuously heated, the energy output by the heating part at the beginning is too much, which causes the temperature of the aerosol generating substrate to exceed 350 degrees, and even the aerosol generating substrate burns, which brings safety risks and bad smoking experience to the customer.

That is, these functional entities can be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0043] Temperature is an external manifestation of energy. In the actual heating process of the heating-not-burning aerosol generating device (hereinafter referred to as HNB), the temperature inside the aerosol generating substrate is a manifestation of the accumulation of energy inside the aerosol generating substrate. The purpose of the present application is to make the energy accumulation inside the aerosol generating substrate not exceed a certain threshold, so as to ensure that the temperature of the aerosol generating substrate does not exceed the temperature required for medium combustion, reduce the safety risk, and improve the user's smoking experience.

[0044] In some embodiments, the aerosol generating substrate is pluggably accommodated in the heating-not-burning aerosol generating device, and the aerosol generating substrate can be a columnar aerosol generating article. Specifically, the aerosol generating substrate can be a solid material made of leaves and / or stems of plants, and further aroma components can be added in the solid material. It can be understood that in other embodiments, the aerosol generating substrate can be a sheet-shaped or a cylindrical aerosol generating article, which is not limited herein.

[0045] As shown in FIG. 1, one embodiment of the present application discloses an energy supply method of a heat-not-burn aerosol generating device, which comprises a heating body for heating a heat-not-burn aerosol generating substrate to generate an aerosol for a user to inhale. The energy supply method is an energy supply scheme for a user when the heat-not-burn aerosol generating device is in a hot machine state and continuously heats a plurality of aerosol generating substrates, wherein the continuous heating comprises heating a plurality of aerosol generating articles within a preset time range. Specifically, the energy supply method comprises the following steps:

[0046] receiving a start instruction;

[0047] When it is detected that the heat-not-burn aerosol generating device is in the hot machine state and it is determined that the number of continuously heated aerosol generating substrates reaches a preset number threshold, the energy supply to the heating body is stopped, so as to ensure that the temperature of the aerosol generating substrate does not exceed the temperature required for medium combustion, reduce the safety risk, and improve the user's smoking experience. For example, the preset number threshold is 3, which is only an example and does not limit the present application.

[0048] In some embodiments, the start instruction can be a press instruction, a touch instruction or a voice instruction input by the user or a heating instruction triggered by an air flow sensor.

[0049] In some embodiments, the heating body is an infrared heating body, which radiates infrared light to the outer periphery or the inside of the aerosol generating substrate, and the infrared light is used to heat the aerosol generating substrate. Specifically, the heat-not-burn aerosol generating device comprises an infrared heating body and a power supply assembly for supplying power to the infrared heating body. The infrared heating body can be partially inserted into the inside of the aerosol generating article, or at least one infrared heating body is located at the outer periphery of the aerosol generating article. It can be understood that in other embodiments, there can be at least two, three or any number of infrared heating bodies, which are not limited herein. The infrared heating body generates infrared light in the powered state to heat the medium segment of the aerosol generating article to generate an aerosol.

[0050] The infrared heating body comprises a tube body (such as a quartz tube), a heating body and a base. The tube body contains at least part of the heating body, and the infrared light radiated by the heating body can pass through the tube body to heat the aerosol generating article. The base is arranged at the opening of the tube body and is used to fix the tube body. The heating body comprises a heating base and an infrared radiation layer arranged on the outer surface of the heating base. The heating base can excite the infrared radiation layer to generate infrared light and radiate it in the powered heating state. It should be noted that the infrared heating body is only an example and does not limit the present application.

[0051] In some embodiments, when it is detected that the heat-not-burn aerosol generating device is in the hot machine state, specifically comprising:

[0052] detecting that the heating body is heating;

[0053] determining that the cold and hot degree index of the heat-not-burn aerosol generating device is greater than the preset index threshold, and the heat-not-burn aerosol generating device is in a hot engine state.

[0054] The cold and hot degree index of the heat-not-burn aerosol generating device can be expressed by a percentage, for example, the preset index threshold is 70%, and the 70% is only an example and does not limit the present application.

[0055] In some embodiments, the hot engine state can be determined by dividing the state of the heat-not-burn aerosol generating device into two fuzzy sets of the hot engine state and the cold engine state, and calculating the hot engine membership of the heat-not-burn aerosol generating device by a preset membership function. Specifically, first, the temperature rise slope K of the heating body is calculated, the temperature rise slope K is fuzzified, and then fuzzy control algorithm is used for fuzzy control rule processing, fuzzy decision processing and fuzzy logic processing to obtain the fuzzified hot engine membership. Then, the hot engine membership A is obtained by de-fuzzification calculation, for example, if the temperature rise slope K is less than or equal to 0.8, the hot engine membership A is 100%, and if the temperature rise slope K is greater than or equal to 7, the hot engine membership A is a preset value. If the hot engine membership A is greater than 70%, it is determined that the heat-not-burn aerosol generating device is in a hot engine state. The temperature rise slope K can be calculated as follows: K = (Tsense(t1)'-Tenv(t0)) / Tenv(t0), wherein Tenv(t0) represents the ambient temperature, Tsense(t1)' represents the heating body temperature after calibration correction after a preset heating time t1, and the calibration correction method can be obtained by establishing a mathematical model of the ambient temperature, the aerosol generating substrate receiving cavity temperature, the heating body temperature obtained by the temperature sensor after the preset heating time t1, and the real temperature of the heating body after the preset heating time t1. This will not be described here.

[0056] In some embodiments, the heat-not-burn aerosol generating device further comprises an aerosol generating substrate receiving cavity, i.e., a cavity for accommodating aerosol generating substrate and generating aerosol. The cold and hot degree index of the heat-not-burn aerosol generating device is obtained, specifically including:

[0057] obtaining the ambient temperature, the aerosol generating substrate receiving cavity temperature and the heating body temperature;

[0058] obtaining the cold and hot degree index of the heat-not-burn aerosol generating device according to the ambient temperature, the aerosol generating substrate receiving cavity temperature and the heating body temperature.

[0059] In some embodiments, the heat-not-burn aerosol generating device further comprises a microprocessor (such as an MCU) and a charging end. The ambient temperature is obtained by specifically comprising:

[0060] The internal temperature of the microprocessor and the temperature of the charging end are obtained and fused to obtain the ambient temperature.

[0061] Specifically, the ambient temperature refers to the temperature of the external environment in which the heat-not-burn aerosol generating device is located. If the heat-not-burn aerosol generating device is in an indoor environment, the ambient temperature is equal to the temperature of the indoor environment. If the heat-not-burn aerosol generating device is in an outdoor environment, the ambient temperature is equal to the temperature of the outdoor environment.

[0062] Within a preset time (such as 800 ms) after starting heating, the internal temperature of the microprocessor and the temperature of the charging end are collected by the existing microprocessor and the thermistor at the charging end, and then fused to calculate the ambient temperature at low cost and accurately. The fusion calculation is: ambient temperature = A*internal temperature of microprocessor + B*temperature of charging end, where (A+B)=100%, and the specific values of A and B can be fitted by experimental data.

[0063] In other embodiments, the charging end is exposed, and the microprocessor is located inside the device. When the heat-not-burn aerosol generating device is in a cold state, the internal temperature of the microprocessor and the temperature of the charging end are not much different. In the case of little difference, the temperature measured by the microprocessor will be more accurate, and the internal temperature of the microprocessor will be taken as the ambient temperature. In the hot state, the internal temperature of the microprocessor and the temperature of the charging end may be different. In the case of large difference, the temperature of the charging end will be taken as the ambient temperature.

[0064] In some embodiments, the heat-not-burn aerosol generating device further comprises a preset circuit board (such as a main control board) at the bottom of the aerosol generating substrate receiving cavity and a battery. The temperature of the aerosol generating substrate receiving cavity is obtained by specifically comprising:

[0065] The temperature of the preset circuit board and the temperature of the battery are obtained and fused to obtain the temperature of the aerosol generating substrate receiving cavity.

[0066] Specifically, since the preset circuit board and the battery are close to the bottom of the aerosol generating substrate receiving cavity, the temperature of the preset circuit board and the temperature of the battery can be collected by the thermistors at the preset circuit board and the battery, and then fused to calculate the temperature of the aerosol generating substrate receiving cavity at low cost and accurately. The fusion calculation is: aerosol generating substrate receiving cavity temperature = C*pre-set circuit board temperature + D*battery temperature, where (C+D)=100%, and the specific values of C and D can be fitted by experimental data.

[0067] In some embodiments, as shown in FIG. 1, when it is determined that the number of continuously heated aerosol generating substrates does not reach the preset number threshold, the heating element energy is supplied according to the current puffing state.

[0068] In some embodiments, as shown in FIG. 2, the supplying of the heating element energy according to the current puffing state is a case when a user puffs one aerosol generating substrate (such as one aerosol generating article), and specifically includes:

[0069] obtaining a basic puffing interval duration according to a preset basic energy supply model;

[0070] obtaining a current puffing duration and a current puffing interval duration when it is detected that the puffing occurs;

[0071] when it is determined that the current puffing interval duration is greater than the basic puffing interval duration, correcting the preset basic energy supply model according to the current puffing duration and the current puffing interval duration, and supplying the heating element energy according to the corrected basic energy supply model.

[0072] In some embodiments, the supplying of the heating element energy according to the current puffing state further includes:

[0073] when it is determined that the current puffing interval duration is less than or equal to the basic puffing interval duration, supplying the heating element energy according to the preset basic energy supply model. Because on the basis of the preset basic energy supply model, if the energy value is slightly increased, it is easy to cause the temperature of the aerosol generating substrate to exceed the temperature required for medium combustion.

[0074] In some embodiments, the correcting of the preset basic energy supply model according to the current puffing duration and the current puffing interval duration includes:

[0075] increasing the energy value on the basis of the preset basic energy supply model according to the current puffing duration and the current puffing interval duration to correct the preset basic energy supply model and obtain a corrected basic energy supply model.

[0076] In the preset basic energy supply model, the energy supply for the basic puffing duration can be maintained, and only according to the current puffing duration and the current puffing interval duration, the energy value is additionally increased on the basis of the preset basic energy supply model. Increasing the energy value is to supplement the energy of the aerosol generating substrate. The corrected basic energy supply model can still ensure that in the current puffing state where the current puffing interval duration is greater than the basic puffing interval duration, the temperature of the aerosol generating substrate does not exceed the temperature required for medium combustion, and the aerosol generating substrate is just heated to a sufficient degree to emit a specific taste.

[0077] It needs to be explained that the energy supply model: in the actual heating process of the heat-not-burn aerosol generating device, the temperature is a scalar of energy, and all the energy is supplied by the battery. Without the energy supply of the battery, the aerosol generating substrate cannot be heated to generate aerosol, and there can be no significant temperature change. From this principle, if the energy supply can be accurately controlled, the generation of aerosol can also be accurately controlled. Temperature is only used as a scale to monitor whether the temperature exceeds the standard (abnormal conditions such as too high or too low temperature) caused by out-of-control energy supply. Based on this, the correlation between aerosol generation and power heating control can be analyzed based on the heating energy transfer model and the relationship between aerosol generation and energy, and a suitable power control scheme can be designed.

[0078] The basic energy supply model in the embodiment is obtained by the following method: according to the preset puffing state (such as puffing for 2s and stopping for 8s), different energy supplies are given, and a plurality of users rate, find the corresponding energy data that a plurality of users think is good in taste, and obtain the basic energy supply model.

[0079] It needs to be explained that the energy supply control is equivalent to power control (energy is the integral of power over time), which is particularly suitable for heat-not-burn aerosol generating devices that use infrared heating. The amplitude, duty cycle, and frequency of power affect the energy supply. In the case where the frequency remains unchanged, the amplitude and duty cycle of the power can be adjusted to achieve energy regulation. Different amplitudes and duty cycles affect the ratio of thermal radiation and heat conduction, and the ratio of thermal radiation and heat conduction supplied to the aerosol generating substrate can be adjusted according to the characteristics of the aerosol generating substrate to achieve a better taste. In combination with user evaluation, the best basic energy supply model can be found.

[0080] In some embodiments, detecting that puffing occurs specifically includes: obtaining the temperature of the heating body, and determining that puffing occurs according to the change of the temperature of the heating body, for example, a higher temperature represents that puffing occurs.

[0081] Correspondingly, the current puffing duration and the current puffing interval duration are obtained, specifically including: obtaining the current puffing duration and the current puffing interval duration according to the relationship between the current temperature of the heating body and the time, for example, puffing for 2s and stopping for 3s. It needs to be explained here that the puffing for 2s and stopping for 3s is only an example and does not limit the present application, and the 2s puffing is one puffing for 2s.

[0082] In some embodiments, the preset basic energy supply model is a preset output power-time curve, and the curve is determined according to a preset puffing state (for example, 2s puffing and 8s pausing), and the basic puffing duration and the basic puffing interval duration can be obtained according to the preset output power-time curve. The energy value is increased, that is, the output power is increased. It should be noted that the 2s puffing and 8s pausing is only an example and does not limit the present application.

[0083] In the preset puffing state or the current puffing state in which the current puffing interval duration is less than or equal to the basic puffing interval duration, the preset basic energy supply model can ensure that the temperature of the aerosol generating substrate does not exceed the temperature required for medium combustion and that the aerosol generating substrate is just heated to a sufficient degree to emit a specific taste.

[0084] As shown in FIG. 3, one embodiment of the present application further discloses a heating non-combustion aerosol generating device, comprising:

[0085] a heating body for heating the non-combustion aerosol generating substrate to generate an aerosol for a user to puff;

[0086] a control component configured to:

[0087] receive a starting instruction;

[0088] when it is detected that the heating non-combustion aerosol generating device is in a hot engine state and it is determined that the number of continuously heated aerosol generating substrates reaches a preset number threshold, stop supplying energy to the heating body, so as to ensure that the temperature of the aerosol generating substrate does not exceed the temperature required for medium combustion, reduce the safety risk, and improve the user's puffing experience. For example, the preset number threshold is 3, and the 3 is only an example and does not limit the present application. The continuous heating includes heating a plurality of aerosol generating articles within a preset time range.

[0089] In some embodiments, the starting instruction can be a pressing instruction, a touch instruction or a voice instruction input by a user or a heating instruction triggered by an air flow sensor.

[0090] In some embodiments, the heating body is an infrared heating body, which radiates infrared light to the outer periphery or the inside of the aerosol generating substrate, and the infrared light is used to heat the aerosol generating substrate. Specifically, the heating non-combustion aerosol generating device comprises an infrared heating body and a power supply component for supplying power to the infrared heating body. The infrared heating body can be partially inserted into the inside of the aerosol generating article, or at least one infrared heating body is located at the outer periphery of the aerosol generating article. It can be understood that in some other embodiments, there can be at least two, three or any number of infrared heating bodies, which are not limited herein. The infrared heating body generates infrared light in the power-on state to heat the medium segment of the aerosol generating article to generate an aerosol.

[0091] The infrared heating body includes a tube body (such as a quartz tube), a heating body, and a base. The tube body houses at least part of the heating body and allows infrared light emitted by the heating body to pass through, thereby heating the aerosol generating article. The base is arranged at an opening of the tube body and is used to fix the tube body. The heating body includes a heating base and an infrared radiation layer arranged on an outer surface of the heating base. The heating base can excite the infrared radiation layer to generate and radiate infrared light in an energized and heated state. It should be noted that the infrared heating body is only an example and does not limit the present application.

[0092] In some embodiments, the heating-not-burning aerosol generating device is determined to be in a hot state, specifically including:

[0093] When the heating body is determined to be heating, a cold and hot degree index of the heating-not-burning aerosol generating device is obtained.

[0094] When the cold and hot degree index of the heating-not-burning aerosol generating device is greater than a preset index threshold, the heating-not-burning aerosol generating device is determined to be in a hot state.

[0095] The cold and hot degree index of the heating-not-burning aerosol generating device can be expressed as a percentage, for example, the preset index threshold is 70%. The 70% is only an example and does not limit the present application.

[0096] In some embodiments, the hot state can be determined by dividing the state of the heating-not-burning aerosol generating device into two fuzzy sets, a hot state and a cold state, and calculating the hot membership degree of the heating-not-burning aerosol generating device by a preset membership function. Specifically, first, the temperature rise slope K of the heating body is calculated, the temperature rise slope K is fuzzified, and then the fuzzy control algorithm is used for fuzzy control rule processing, fuzzy decision processing, and fuzzy logic processing to obtain the fuzzified hot membership degree. The hot membership degree A can be obtained by de-fuzzification calculation, for example, if the temperature rise slope K is less than or equal to 0.8, the hot membership degree A is 100%, and if the temperature rise slope K is greater than or equal to 7, the hot membership degree A is a preset value. If the hot membership degree A is greater than 70%, the heating-not-burning aerosol generating device is determined to be in a hot state. The temperature rise slope K can be calculated as follows: K = (Tsense(t1)' - Tenv(t0)) / Tenv(t0), where Tenv(t0) represents the ambient temperature, Tsense(t1)' represents the heating body temperature after calibration correction after a heating preset time t1, and the calibration correction method can use the ambient temperature, the aerosol generating substrate receiving cavity temperature, the heating body temperature obtained by the temperature sensor after the heating preset time t1, and the heating body true temperature after the heating preset time t1 to establish a mathematical model and calculate the result.

[0097] In some embodiments, the heat-not-burn aerosol generating device further comprises an aerosol generating substrate accommodation cavity, i.e., a cavity for accommodating an aerosol generating substrate and generating an aerosol. The cold and hot degree index of the heat-not-burn aerosol generating device is obtained, specifically comprising:

[0098] obtaining the ambient temperature, the aerosol generating substrate accommodation cavity temperature and the heating element temperature;

[0099] obtaining the cold and hot degree index of the heat-not-burn aerosol generating device according to the ambient temperature, the aerosol generating substrate accommodation cavity temperature and the heating element temperature.

[0100] In some embodiments, the heat-not-burn aerosol generating device further comprises a temperature sensor for measuring the heating element temperature.

[0101] In some embodiments, the heat-not-burn aerosol generating device further comprises a microprocessor (such as an MCU) and a charging end. The ambient temperature is obtained, specifically comprising:

[0102] obtaining the internal temperature of the microprocessor and the temperature of the charging end, and performing fusion calculation to obtain the ambient temperature.

[0103] Specifically, the ambient temperature refers to the temperature in the external environment where the heat-not-burn aerosol generating device is located. If the heat-not-burn aerosol generating device is in an indoor environment, the ambient temperature is equal to the temperature in the indoor environment. If the heat-not-burn aerosol generating device is in an outdoor environment, the ambient temperature is equal to the temperature in the outdoor environment.

[0104] Within a preset time (such as 800 ms) after starting heating, the internal temperature of the microprocessor and the temperature of the charging end are collected through the existing microprocessor and the thermistor at the charging end, and then fusion calculation is performed, so that the ambient temperature can be calculated accurately and at low cost. The fusion calculation is: ambient temperature = A*internal temperature of microprocessor + B*temperature of charging end, wherein (A+B)=100%, and the specific values of A and B can be fitted through experimental data.

[0105] In other embodiments, the charging end is exposed, and the microprocessor is located inside the device. When the heat-not-burn aerosol generating device is in a cold state, the internal temperature of the microprocessor and the temperature of the charging end are not much different. In the case of little difference, the temperature measured by the microprocessor will be more accurate, and the internal temperature of the microprocessor will be taken as the ambient temperature. When the heat-not-burn aerosol generating device is in a hot state, the internal temperature of the microprocessor and the temperature of the charging end can be different. In the case of large difference, the temperature of the charging end will be taken as the ambient temperature.

[0106] In some embodiments, the heat-not-burn aerosol generating device further comprises a preset circuit board (such as a main control board) and a battery located at the bottom of the aerosol generating substrate receiving cavity. The temperature of the aerosol generating substrate receiving cavity is obtained by:

[0107] The temperature of the preset circuit board and the temperature of the battery are obtained and fused to obtain the temperature of the aerosol generating substrate receiving cavity.

[0108] Specifically, since the preset circuit board and the battery are close to the bottom of the aerosol generating substrate receiving cavity, the temperature of the preset circuit board and the temperature of the battery can be collected by the thermistors at the preset circuit board and the battery, and then fused to calculate the temperature of the aerosol generating substrate receiving cavity at low cost and accurately. The fusion calculation is: the temperature of the aerosol generating substrate receiving cavity = C*the temperature of the preset circuit board + D*the temperature of the battery, wherein (C+D)=100%, and the specific values of C and D can be fitted by experimental data.

[0109] In some embodiments, the control component is further configured to:

[0110] When the number of continuously heated aerosol generating substrates does not reach the preset number threshold, the heating element energy is supplied according to the current puffing state.

[0111] In some embodiments, the heating element energy is supplied according to the current puffing state when a user puffs one aerosol generating substrate (such as one aerosol generating article), and specifically includes:

[0112] According to the preset basic energy supply model, the basic puffing interval duration is obtained;

[0113] When the puffing is detected, the current puffing duration and the current puffing interval duration are obtained;

[0114] When the current puffing interval duration is greater than the basic puffing interval duration, the preset basic energy supply model is corrected according to the current puffing duration and the current puffing interval duration, and the heating element energy is supplied according to the corrected basic energy supply model.

[0115] In some embodiments, the heating element energy is supplied according to the current puffing state, and specifically further includes:

[0116] When the current puffing interval duration is less than or equal to the basic puffing interval duration, the heating element energy is supplied according to the preset basic energy supply model. Because if the energy value is slightly increased on the basis of the preset basic energy supply model, it is easy to cause the temperature of the aerosol generating substrate to exceed the temperature required for medium combustion.

[0117] In some embodiments, the preset basic energy supply model is corrected according to the current puffing duration and the current puffing interval duration, specifically including:

[0118] According to the current puffing duration and the current puffing interval duration, the energy value is additionally increased on the basis of the preset basic energy supply model to correct the preset basic energy supply model, and a corrected basic energy supply model is obtained.

[0119] In the preset basic energy supply model, the energy supply for the basic puffing duration can be maintained, and only according to the current puffing duration and the current puffing interval duration, the energy value is additionally increased on the basis of the preset basic energy supply model. Increasing the energy value is to supplement the energy of the aerosol generating substrate. The corrected basic energy supply model can still ensure that the temperature of the aerosol generating substrate does not exceed the temperature required for medium combustion in the current puffing state where the current puffing interval duration is greater than the basic puffing interval duration, and the aerosol generating substrate is just heated to a sufficient degree to emit a specific taste.

[0120] It needs to be explained that the energy supply model is that in the actual heating process of the heat-not-burn aerosol generating device, temperature is a scalar of energy, and all the energy is derived from the power supply of the battery. Without the power supply of the battery, the aerosol generating substrate cannot be heated to generate aerosol, and there cannot be a significant temperature change. From this principle, if the energy supply can be accurately controlled, the generation of aerosol can also be accurately controlled. Temperature is only used as a scale to monitor whether the temperature exceeds the standard (abnormal conditions such as too high or too low temperature) caused by uncontrolled energy supply. Based on this, the correlation between aerosol generation and power heating control can be analyzed based on the energy transfer model of heating and the relationship model of aerosol generation and energy, and a suitable power control scheme can be designed.

[0121] In the present embodiment, the basic energy supply model is obtained by the following method. Different energy supplies are given according to the preset puffing state (such as puffing for 2s and pausing for 8s), and the corresponding energy data that multiple users think is good in taste is found by scoring by multiple users, and the basic energy supply model is obtained.

[0122] It needs to be explained that the energy supply control is equivalent to power control (energy is the integral of power over time), which is particularly suitable for heat-not-burn aerosol generating devices that use infrared heating. The amplitude, duty cycle, and frequency of power affect the energy supply. In the case where the frequency remains unchanged, the energy can be adjusted by adjusting the amplitude and duty cycle of the power. Different amplitudes and duty cycles affect the ratio of thermal radiation and thermal conduction, which can be adjusted according to the characteristics of the aerosol generating substrate to achieve a better taste. In combination with user evaluation, the best basic energy supply model can be found.

[0123] In some embodiments, the detection of the puffing includes: obtaining the temperature of the heating body, and determining the occurrence of the puffing according to the change of the temperature of the heating body, for example, the temperature is increased, which represents the occurrence of the puffing.

[0124] Correspondingly, the current puffing duration and the current puffing interval duration are obtained, specifically including: obtaining the current puffing duration and the current puffing interval duration according to the relationship between the current temperature of the heating body and the time, for example, 2s puffing and 3s interval. It should be noted that the 2s puffing and 3s interval here is only an example and does not limit the present application, and the 2s puffing is 2s of a puff.

[0125] In some embodiments, the preset basic energy supply model is a preset output power-time relationship curve, and the curve is determined according to a preset puffing state (such as 2s puffing and 8s interval), and the basic puffing duration and the basic puffing interval duration can be obtained through the preset output power-time relationship. The energy value is increased, that is, the output power is increased. It should be noted that the 2s puffing and 8s interval here is only an example and does not limit the present application.

[0126] In the preset puffing state or the current puffing state in which the current puffing interval duration is less than or equal to the basic puffing interval duration, the preset basic energy supply model can ensure that the temperature of the aerosol generating substrate does not exceed the temperature required for medium combustion, and the aerosol generating substrate is just heated to a sufficient degree to emit a specific taste.

[0127] By implementing the present application, the following beneficial effects are achieved:

[0128] After receiving the start instruction, the present application detects that the heat-not-burn aerosol generating device is in a hot engine state, and determines that the number of continuously heated aerosol generating substrates reaches a preset number threshold, and then stops supplying energy to the heating body. Therefore, when a plurality of aerosol generating substrates are continuously heated, the temperature of the aerosol generating substrate can be ensured to be less than the temperature required for medium combustion, the safety risk is reduced, and the user's smoking experience is improved.

[0129] It can be understood that the above embodiments only express some implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the patent of the present application.
