Description

Technical Field

[0001] This invention relates to the technical field of heated non-combustible aerosol generating devices, and more particularly to a heated non-combustible aerosol generating device and its energy supply method. Background Technology

[0002] The working principle of a heat-not-burning (HNB) aerosol generator is to produce aerosols by heating a non-combustible aerosol generating substrate. The device mainly consists of an aerosol generating substrate, a heating section, a temperature feedback section, and a charging section. During operation, the HNB aerosol generator typically uses a specific algorithm to control the heating power output of the heating section based on the difference between the substrate temperature fed back by the temperature sensor and the set target temperature. This keeps the heating temperature within the range of 200-350 degrees Celsius, ensuring the aerosol generating substrate is heated just enough to emit a specific odor. However, when the aerosol generating matrix is ​​initially inserted into the heated non-combustible aerosol generating device, the temperature sensor cannot accurately measure the matrix temperature at the beginning because it takes time for energy to be conducted from the heating part to the aerosol generating matrix. The measured matrix temperature has a certain lag. Therefore, the power is initially output according to time. This results in excessive energy output from the heating part when heating multiple aerosol generating matrices continuously, causing the temperature of the aerosol generating matrix to exceed 350 degrees Celsius, or even causing the aerosol generating matrix to burn, posing safety risks and a poor suction experience for customers. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to address at least one defect of the related technologies mentioned in the background art: when multiple aerosol generating matrices are continuously heated, the temperature of the aerosol generating matrices may become too high. The present invention provides a heating non-combustible aerosol generating device and its energy supply method.

[0004] The technical solution adopted by this invention to solve its technical problem is: an energy supply method for a heated non-combustible aerosol generating device, wherein the heated non-combustible aerosol generating device includes a heating element, and the energy supply method includes the following steps:

[0005] Receive startup command;

[0006] When the heated non-combustible aerosol generating device is detected to be in a hot-engine state, and when it is determined that the number of continuously heated aerosol generating substrates has reached a preset quantity threshold, the energy supply to the heating element is stopped.

[0007] Preferably, if it is determined that the amount of continuously heated aerosol generating matrix has not reached a preset quantity threshold, then energy is supplied to the heating element according to the current suction state.

[0008] Preferably, detecting that the heated non-combustible aerosol generating device is in a hot-engine state includes:

[0009] When the heating element is detected to be heating, the temperature index of the heating non-combustible aerosol generating device is obtained;

[0010] If the temperature index of the heated non-combustible aerosol generating device is greater than a preset threshold, then the heated non-combustible aerosol generating device is in a hot-engine state.

[0011] Preferably, the heated non-combustible aerosol generating device further includes an aerosol generating matrix containing cavity;

[0012] Obtaining the thermal index of the heated non-combustible aerosol generating device includes:

[0013] The ambient temperature, the temperature of the aerosol generation matrix containment cavity, and the temperature of the heating element are obtained.

[0014] The temperature index of the heated non-combustible aerosol generating device is obtained based on the ambient temperature, the temperature of the aerosol generating matrix containment cavity, and the temperature of the heating element.

[0015] Preferably, the heated non-combustible aerosol generating device further includes a microprocessor and a charging terminal;

[0016] Obtain the ambient temperature, including:

[0017] The temperature inside the microprocessor and the temperature at the charging terminal are obtained and fused together to obtain the ambient temperature.

[0018] Preferably, the heated non-combustible aerosol generating device further includes a pre-set circuit board and a battery located at the bottom of the aerosol generating matrix receiving cavity;

[0021] Preferably, supplying energy to the heating element according to the current suction state includes:

[0022] Based on the preset basic energy supply model, the basic suction interval duration is obtained;

[0023] When aspiration is detected, obtain the current aspiration duration and the current aspiration interval duration;

[0024] If the current suction interval duration is greater than the base suction interval duration, the preset base energy supply model is corrected based on the current suction duration and the current suction interval duration, and the heating element is supplied with energy according to the corrected base energy supply model.

[0025] Preferably, supplying energy to the heating element according to the current suction state further includes:

[0026] If the current suction interval is less than or equal to the basic suction interval, then the heating element is supplied with energy according to the preset basic energy supply model.

[0027] Preferably, the preset basic energy supply model is modified based on the current suction duration and the current suction interval duration, including:

[0028] Based on the current suction duration and the current suction interval, the energy value is increased by an additional amount to correct the preset basic energy supply model, resulting in the corrected basic energy supply model.

[0029] The present invention also provides a heating non-combustible aerosol generating device, comprising:

[0030] Heating element;

[0031] Control component, the control component being configured to:

[0032] Receive startup command;

[0033] When the heated non-combustible aerosol generating device is detected to be in a hot-engine state, and when it is determined that the number of continuously heated aerosol generating substrates has reached a preset quantity threshold, the energy supply to the heating element is stopped.

[0034] By implementing this invention, the following beneficial effects are achieved:

[0035] Upon receiving a start command, this invention detects that the heated non-combustible aerosol generating device is in a hot-engine state and determines that the number of continuously heated aerosol generating substrates has reached a preset threshold. In this way, it stops supplying energy to the heating element, thereby ensuring that the temperature of the aerosol generating substrates does not exceed the temperature required for the combustion of the medium when multiple aerosol generating substrates are continuously heated, reducing safety risks and improving the user's suction experience.

[0039] Figure 3 This is a logic structure diagram of an embodiment of the heated non-combustible aerosol generating device of the present invention. Detailed Implementation

[0040] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0041] It should be noted that the flowcharts shown in the accompanying drawings are merely illustrative and do not necessarily include all content and operations / steps, nor do they necessarily have to be performed in the described order. For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0042] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software, 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 a heated non-combustible aerosol generator (HNB), the temperature inside the aerosol generating matrix is ​​a reflection of the energy accumulation within the matrix. The purpose of this invention is to ensure that the energy accumulation inside the aerosol generating matrix does not exceed a specific threshold, thereby guaranteeing that the temperature of the aerosol generating matrix does not exceed the temperature required for combustion of the medium, reducing safety risks, and improving the user's suction experience.

[0044] In some embodiments, the aerosol generating matrix is ​​pluggably housed in a heated non-combustible aerosol generating device. The aerosol generating matrix can be a columnar aerosol generating product, specifically a solid material made from plant leaves and / or stems, and aroma components can be further added to the solid material. Understandably, in other embodiments, the aerosol generating matrix can be a sheet-like or cylindrical aerosol generating product, and this is not limited thereto.

[0045] like Figure 1As shown, one embodiment of the present invention discloses an energy supply method for a heated non-combustible aerosol generating device. The heated non-combustible aerosol generating device includes a heating element used to heat a non-combustible aerosol generating matrix to generate aerosols for user inhalation. This energy supply method is an energy supply scheme for users continuously heating multiple aerosol generating matrices when the heated non-combustible aerosol generating device is in a hot-running state. Continuous heating includes heating multiple aerosol generating products within a preset time range. Specifically, the energy supply method includes the following steps:

[0046] Receive startup command;

[0047] When the heated non-combustible aerosol generator is detected to be in a hot-engine state, and when the amount of continuously heated aerosol generation matrix is ​​determined to have reached a preset quantity threshold, the energy supply to the heating element is stopped. This ensures that the temperature of the aerosol generation matrix does not exceed the temperature required for medium combustion, reducing safety risks and improving the user's pumping experience. For example, the preset quantity threshold is 3. The number 3 here is merely an example and is not intended to limit this application.

[0048] In some embodiments, the activation command may be a user-inputted press command, touch command, or voice command, or a heating command triggered by an airflow sensor, etc.

[0049] In some embodiments, the heating element is an infrared heating element that radiates infrared light around or inside the aerosol-generating matrix. This infrared light is used to heat the aerosol-generating matrix. Specifically, the heated non-combustible aerosol generating device includes an infrared heating element and a power supply component for supplying power to the infrared heating element. The infrared heating element may be partially inserted into the interior of the aerosol-generating article, or at least one infrared heating element may be located around the outer periphery of the aerosol-generating article. Understandably, in other embodiments, there may be at least two, three, or any number of infrared heating elements, which is not limited here. When energized, the infrared heating element generates infrared light to heat the medium section of the aerosol-generating article, causing it to generate aerosols.

[0050] The infrared heating element includes a tube (such as a quartz tube), a heating body, and a base. The tube houses at least a portion of the heating body, allowing infrared light radiated by the heating body to pass through, thereby heating the aerosol-generated product. The base is located at the opening of the tube and is used to fix the tube. The heating body includes a heating substrate and an infrared radiation layer disposed on the outer surface of the heating substrate. When electrically heated, the heating substrate can excite the infrared radiation layer to generate and radiate infrared light. It should be noted that the infrared heating element described here is merely an example and is not intended to limit the scope of this application.

[0051] In some embodiments, detecting that the heated non-combustible aerosol generating device is in a hot-engine state specifically includes:

[0052] When the heating element is detected to be heating, the temperature index of the heating non-combustible aerosol generating device is obtained;

[0053] If the temperature index of the heated non-combustible aerosol generating device exceeds the preset threshold, the heated non-combustible aerosol generating device is in a hot-engine state.

[0054] The degree of hotness or coldness of the heated non-combustible aerosol generating device can be expressed as a percentage, for example, a preset threshold of 70%. The 70% here is just an example and is not intended to limit this application.

[0055] In some embodiments, the hot-engine state can be determined by dividing the state of the heated non-combustible aerosol generating device into two fuzzy sets: a hot-engine state and a cold-engine state. The hot-engine membership degree of the heated non-combustible aerosol generating device is calculated using a preset membership function. Specifically, first, the temperature rise slope K of the heating element is calculated. The temperature rise slope K is then fuzzified. A fuzzy control algorithm is then used for fuzzy control rule processing, fuzzy decision processing, and fuzzy logic processing to obtain the fuzzified hot-engine membership degree. This fuzzification is then performed to obtain the hot-engine membership degree A. For example, if the temperature rise slope K is less than or equal to 0.8, the hot-engine membership degree A is 100%. If the temperature rise slope K is greater than or equal to 7, the hot-engine membership degree A is a preset value. If the hot-engine membership degree A is greater than 70%, the heated non-combustible aerosol generating device is determined to be in a hot-engine 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 and Tsense(t1)' represents the calibrated and corrected temperature of the heating element after a preset heating time t1. The calibration and correction method can be calculated by establishing a mathematical model based on the ambient temperature, the temperature of the aerosol generation matrix containment cavity, the temperature of the heating element obtained by the temperature sensor after a preset heating time t1, and the actual temperature of the heating element after a preset heating time t1. This will not be elaborated further here.

[0056] In some embodiments, the heated non-combustible aerosol generating device further includes an aerosol generating matrix containing cavity, i.e., a cavity for containing the aerosol generating matrix and generating aerosols. The specific methods for obtaining the thermal index of the heated non-combustible aerosol generating device include:

[0057] The ambient temperature, the temperature of the aerosol generation matrix containment cavity, and the temperature of the heating element are obtained.

[0058] The temperature index of the heated non-combustible aerosol generating device is obtained based on the ambient temperature, the temperature of the aerosol generating matrix containment cavity, and the temperature of the heating element.

[0059] In some embodiments, the heated non-combustible aerosol generating device further includes a microprocessor (such as an MCU) and a charging terminal. Acquiring the ambient temperature specifically includes:

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

[0061] Specifically, ambient temperature refers to the temperature of the external environment in which the heated non-combustible aerosol generating device is located. If the heated non-combustible aerosol generating device is located indoors, the ambient temperature is equal to the indoor temperature. If the heated non-combustible aerosol generating device is located outdoors, the ambient temperature is equal to the outdoor temperature.

[0062] Within a preset time (e.g., 800ms) after heating is initiated, the internal temperature of the microprocessor and the temperature of the charging terminal are collected using the thermistors at the existing microprocessor and charging terminal. These are then fused together to calculate the ambient temperature accurately and at low cost. The fused calculation is: Ambient temperature = A * Microprocessor internal temperature + B * Charging terminal temperature, where (A + B) = 100%. The specific values ​​of A and B can be fitted using experimental data.

[0063] In some other embodiments, the charging terminal is exposed, while the microprocessor is located inside the device. When the heated non-combustible aerosol generating device is in a cold state, the internal temperature of the microprocessor and the temperature of the charging terminal are not significantly different. In this case, the temperature measured by the microprocessor is more accurate, and the internal temperature of the microprocessor is used as the ambient temperature. However, in a hot state, the internal temperature of the microprocessor and the temperature of the charging terminal may differ significantly. In this case, the temperature of the charging terminal is used as the ambient temperature.

[0064] In some embodiments, the heated non-combustible aerosol generating device further includes a pre-set circuit board (such as a main control board) and a battery located at the bottom of the aerosol generating matrix containment cavity. Obtaining the temperature of the aerosol generating matrix containment cavity specifically includes:

[0065] The temperatures of the preset circuit board and the battery are obtained, and the temperature of the aerosol generation matrix containment cavity is calculated by combining them.

[0066] Specifically, since the preset circuit board and battery are located near the bottom of the aerosol generation matrix containment cavity, the temperatures of the preset circuit board and battery can be collected using thermistors at their locations. These temperatures are then fused together for calculation, allowing for a low-cost and accurate calculation of the aerosol generation matrix containment cavity temperature. The fusion calculation is as follows: Aerosol generation matrix containment cavity temperature = C * preset circuit board temperature + D * battery temperature, where (C + D) = 100%. The specific values ​​of C and D can be fitted using experimental data.

[0067] In some embodiments, such as Figure 1 As shown, if the amount of aerosol-generating matrix generated by continuous heating does not reach the preset threshold, energy is supplied to the heating element according to the current suction state.

[0068] In some embodiments, such as Figure 2 As shown, supplying energy to the heating element based on the current suction state is the case when a user is suctioning an aerosol generation matrix (such as an aerosol generation product), specifically including:

[0069] Based on the preset basic energy supply model, the basic suction interval duration is obtained;

[0070] When aspiration is detected, obtain the current aspiration duration and the current aspiration interval duration;

[0071] If the current suction interval is longer than the base suction interval, the preset base energy supply model is corrected based on the current suction duration and the current suction interval, and the heating element is supplied with energy according to the corrected base energy supply model.

[0072] In some embodiments, energy is supplied to the heating element according to the current suction state, specifically including:

[0073] If the current suction interval is determined to be less than or equal to the base suction interval, then the heating element is supplied with energy according to the preset base energy supply model. This is because, based on the preset base energy supply model, slightly increasing the energy value could easily cause the temperature of the aerosol generation matrix to exceed the temperature required for medium combustion.

[0074] In some embodiments, the preset base energy supply model is modified based on the current suction duration and the current suction interval duration, specifically including:

[0075] Based on the current suction duration and the current suction interval, the energy value is increased to correct the preset basic energy supply model, resulting in a corrected basic energy supply model.

[0076] Specifically, the energy supply for the base suction duration in the preset base energy supply model can be maintained. The energy value is increased based solely on the current suction duration and current suction interval, building upon the preset base energy supply model. This increased energy value replenishes the energy for the aerosol-generating matrix. The modified base energy supply model still ensures that, under the current suction interval longer than the base suction interval, the temperature of the aerosol-generating matrix does not exceed the temperature required for combustion, and that the aerosol-generating matrix is ​​heated just enough to emit a specific odor.

[0077] Regarding the energy supply model, it's important to clarify that in the actual heating process of the heated non-combustible aerosol generator, temperature is a scalar quantity of energy, and all energy originates from battery power. Without battery power, the aerosol generation matrix cannot be heated to produce aerosols, and there will be no significant temperature change. Based on this principle, precise control of the energy supply also allows for precise control of aerosol generation. Temperature serves merely as a benchmark to monitor for any abnormal conditions (such as excessively high or low temperatures) caused by uncontrolled energy supply. Therefore, based on the energy transfer model of heating and the relationship between aerosol generation and energy, the correlation between aerosol generation and power heating control can be analyzed, and a suitable power control scheme can be designed.

[0078] In this embodiment, the basic energy supply model is obtained as follows: based on a preset sucking state (e.g., sucking for 2 seconds and stopping for 8 seconds), different energy supplies are given, and multiple users rate the energy supply. The corresponding energy data that multiple users consider to have good taste is found, and the basic energy supply model is obtained.

[0079] It should be noted that energy supply control is equivalent to power control (energy is the integral of power over time), which is particularly suitable for heated non-combustible aerosol generators that use infrared heating. The energy supply is affected by the power amplitude, duty cycle, and frequency. With the frequency remaining constant, energy can be regulated by adjusting the power amplitude and duty cycle. Furthermore, different amplitudes and duty cycles affect the ratio of heat radiation to heat conduction. The ratio of heat radiation to heat conduction supplied to the aerosol generating matrix can be adjusted according to the characteristics of the aerosol generating matrix to achieve a better taste. In addition, the optimal basic energy supply model can be found by combining user evaluations.

[0080] In some embodiments, detecting suction includes: acquiring the temperature of the heating element and determining whether suction has occurred based on changes in the temperature of the heating element, for example, if the temperature increases, it indicates that suction has occurred.

[0081] Accordingly, the current aspiration duration and the current aspiration interval duration are obtained, specifically including: obtaining the current aspiration duration and the current aspiration interval duration based on the relationship between the current heating element temperature and time, for example, aspiration for 2 seconds and pause for 3 seconds. It should be noted that the aspiration for 2 seconds and pause for 3 seconds here is only an example and is not intended to limit this application, and the aspiration for 2 seconds refers to a single aspiration lasting 2 seconds.

[0082] In some embodiments, the preset basic energy supply model is a preset output power versus time curve, which is determined based on a preset pumping state (e.g., pumping for 2 seconds and stopping for 8 seconds). The basic pumping duration and basic pumping interval can be obtained through the preset output power versus time relationship. Increasing the energy value means increasing the output power. It should be noted that the 2-second pumping and 8-second stopping scenario is merely an example and is not intended to limit this application.

[0083] In the preset suction state or the current suction interval is less than or equal to the basic suction interval, the preset basic energy supply model can ensure that the temperature of the aerosol generation matrix does not exceed the temperature required for medium combustion, and that the aerosol generation matrix is ​​heated just enough to emit a specific odor.

[0084] like Figure 3 As shown, one embodiment of the present invention also discloses a heating non-combustible aerosol generating device, comprising:

[0085] The heating element is used to heat the non-combustible aerosol generating matrix to produce aerosols for users to inhale.

[0086] The control component is configured as follows:

[0087] Receive startup command;

[0088] When the heated non-combustible aerosol generating device is detected to be in a hot-engine state, and it is determined that the number of continuously heated aerosol generating substrates has reached a preset threshold, the energy supply to the heating element is stopped. This ensures that the temperature of the aerosol generating substrate does not exceed the temperature required for medium combustion, reducing safety risks and improving the user's suction experience. For example, the preset threshold is 3; however, 3 is merely an example and not intended to limit this application. Continuous heating includes heating multiple aerosol generating products within a preset time range.

[0089] In some embodiments, the activation command may be a user-inputted press command, touch command, or voice command, or a heating command triggered by an airflow sensor, etc.

[0090] In some embodiments, the heating element is an infrared heating element that radiates infrared light around or inside the aerosol-generating matrix. This infrared light is used to heat the aerosol-generating matrix. Specifically, the heated non-combustible aerosol generating device includes an infrared heating element and a power supply component for supplying power to the infrared heating element. The infrared heating element may be partially inserted into the interior of the aerosol-generating article, or at least one infrared heating element may be located around the outer periphery of the aerosol-generating article. Understandably, in other embodiments, there may be at least two, three, or any number of infrared heating elements, which is not limited here. When energized, the infrared heating element generates infrared light to heat the medium section of the aerosol-generating article, causing it to generate aerosols.

[0091] The infrared heating element includes a tube (such as a quartz tube), a heating body, and a base. The tube houses at least a portion of the heating body, allowing infrared light radiated by the heating body to pass through, thereby heating the aerosol-generated product. The base is located at the opening of the tube and is used to fix the tube. The heating body includes a heating substrate and an infrared radiation layer disposed on the outer surface of the heating substrate. When electrically heated, the heating substrate can excite the infrared radiation layer to generate and radiate infrared light. It should be noted that the infrared heating element described here is merely an example and is not intended to limit the scope of this application.

[0092] In some embodiments, detecting that the heated non-combustible aerosol generating device is in a hot-engine state specifically includes:

[0093] When the heating element is detected to be heating, the temperature index of the heating non-combustible aerosol generating device is obtained;

[0094] If the temperature index of the heated non-combustible aerosol generating device exceeds the preset threshold, the heated non-combustible aerosol generating device is in a hot-engine state.

[0095] The degree of hotness or coldness of the heated non-combustible aerosol generating device can be expressed as a percentage, for example, a preset threshold of 70%. The 70% here is just an example and is not intended to limit this application.

[0096] In some embodiments, the hot-engine state can be determined by dividing the state of the heated non-combustible aerosol generating device into two fuzzy sets: a hot-engine state and a cold-engine state. The hot-engine membership degree of the heated non-combustible aerosol generating device is calculated using a preset membership function. Specifically, first, the temperature rise slope K of the heating element is calculated. The temperature rise slope K is then fuzzified. A fuzzy control algorithm is then used for fuzzy control rule processing, fuzzy decision processing, and fuzzy logic processing to obtain the fuzzified hot-engine membership degree. This fuzzification is then performed to obtain the hot-engine membership degree A. For example, if the temperature rise slope K is less than or equal to 0.8, the hot-engine membership degree A is 100%. If the temperature rise slope K is greater than or equal to 7, the hot-engine membership degree A is a preset value. If the hot-engine membership degree A is greater than 70%, the heated non-combustible aerosol generating device is determined to be in a hot-engine 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 and Tsense(t1)' represents the calibrated and corrected temperature of the heating element after a preset heating time t1. The calibration and correction method can be calculated by establishing a mathematical model based on the ambient temperature, the temperature of the aerosol generation matrix containment cavity, the temperature of the heating element obtained by the temperature sensor after a preset heating time t1, and the actual temperature of the heating element after a preset heating time t1. This will not be elaborated further here.

[0097] In some embodiments, the heated non-combustible aerosol generating device further includes an aerosol generating matrix containing cavity, i.e., a cavity for containing the aerosol generating matrix and generating aerosols. The specific methods for obtaining the thermal index of the heated non-combustible aerosol generating device include:

[0098] The ambient temperature, the temperature of the aerosol generation matrix containment cavity, and the temperature of the heating element are obtained.

[0099] The temperature index of the heated non-combustible aerosol generating device is obtained based on the ambient temperature, the temperature of the aerosol generating matrix containment cavity, and the temperature of the heating element.

[0100] The heated non-combustible aerosol generating device also includes a temperature sensor for measuring the temperature of the heating element.

[0101] In some embodiments, the heated non-combustible aerosol generating device further includes a microprocessor (such as an MCU) and a charging terminal. Acquiring the ambient temperature specifically includes:

[0102] The internal temperature of the microprocessor and the temperature of the charging terminal are obtained and fused to calculate the ambient temperature.

[0103] Specifically, ambient temperature refers to the temperature of the external environment in which the heated non-combustible aerosol generating device is located. If the heated non-combustible aerosol generating device is located indoors, the ambient temperature is equal to the indoor temperature. If the heated non-combustible aerosol generating device is located outdoors, the ambient temperature is equal to the outdoor temperature.

[0104] Within a preset time (e.g., 800ms) after heating is initiated, the internal temperature of the microprocessor and the temperature of the charging terminal are collected using the thermistors at the existing microprocessor and charging terminal. These are then fused together to calculate the ambient temperature accurately and at low cost. The fused calculation is: Ambient temperature = A * Microprocessor internal temperature + B * Charging terminal temperature, where (A + B) = 100%. The specific values ​​of A and B can be fitted using experimental data.

[0105] In some other embodiments, the charging terminal is exposed, while the microprocessor is located inside the device. When the heated non-combustible aerosol generating device is in a cold state, the internal temperature of the microprocessor and the temperature of the charging terminal are not significantly different. In this case, the temperature measured by the microprocessor is more accurate, and the internal temperature of the microprocessor is used as the ambient temperature. However, in a hot state, the internal temperature of the microprocessor and the temperature of the charging terminal may differ significantly. In this case, the temperature of the charging terminal is used as the ambient temperature.

[0106] In some embodiments, the heated non-combustible aerosol generating device further includes a pre-set circuit board (such as a main control board) and a battery located at the bottom of the aerosol generating matrix containment cavity. Obtaining the temperature of the aerosol generating matrix containment cavity specifically includes:

[0107] The temperatures of the preset circuit board and the battery are obtained, and the temperature of the aerosol generation matrix containment cavity is calculated by combining them.

[0108] Specifically, since the preset circuit board and battery are located near the bottom of the aerosol generation matrix containment cavity, the temperatures of the preset circuit board and battery can be collected using thermistors at their locations. These temperatures are then fused together for calculation, allowing for a low-cost and accurate calculation of the aerosol generation matrix containment cavity temperature. The fusion calculation is as follows: Aerosol generation matrix containment cavity temperature = C * preset circuit board temperature + D * battery temperature, where (C + D) = 100%. The specific values ​​of C and D can be fitted using experimental data.

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

[0110] If the amount of aerosol-generating matrix generated by continuous heating does not reach the preset threshold, then energy is supplied to the heating element according to the current suction state.

[0111] In some embodiments, supplying energy to the heating element based on the current suction state is the case when the user is suctioning an aerosol-generating matrix (such as an aerosol-generating article), specifically including:

[0112] Based on the preset basic energy supply model, the basic suction interval duration is obtained;

[0113] When aspiration is detected, obtain the current aspiration duration and the current aspiration interval duration;

[0114] If the current suction interval is longer than the base suction interval, the preset base energy supply model is corrected based on the current suction duration and the current suction interval, and the heating element is supplied with energy according to the corrected base energy supply model.

[0115] In some embodiments, energy is supplied to the heating element according to the current suction state, specifically including:

[0116] If the current suction interval is determined to be less than or equal to the base suction interval, then the heating element is supplied with energy according to the preset base energy supply model. This is because, based on the preset base energy supply model, slightly increasing the energy value could easily cause the temperature of the aerosol generation matrix to exceed the temperature required for medium combustion.

[0117] In some embodiments, the preset base energy supply model is modified based on the current suction duration and the current suction interval duration, specifically including:

[0118] Based on the current suction duration and the current suction interval, the energy value is increased to correct the preset basic energy supply model, resulting in a corrected basic energy supply model.

[0119] Specifically, the energy supply for the base suction duration in the preset base energy supply model can be maintained. The energy value is increased based solely on the current suction duration and current suction interval, building upon the preset base energy supply model. This increased energy value replenishes the energy for the aerosol-generating matrix. The modified base energy supply model still ensures that, under the current suction interval longer than the base suction interval, the temperature of the aerosol-generating matrix does not exceed the temperature required for combustion, and that the aerosol-generating matrix is ​​heated just enough to emit a specific odor.

[0120] Regarding the energy supply model, it's important to clarify that in the actual heating process of the heated non-combustible aerosol generator, temperature is a scalar quantity of energy, and all energy originates from battery power. Without battery power, the aerosol generation matrix cannot be heated to produce aerosols, and there will be no significant temperature change. Based on this principle, precise control of the energy supply also allows for precise control of aerosol generation. Temperature serves merely as a benchmark to monitor for any abnormal conditions (such as excessively high or low temperatures) caused by uncontrolled energy supply. Therefore, based on the energy transfer model of heating and the relationship between aerosol generation and energy, the correlation between aerosol generation and power heating control can be analyzed, and a suitable power control scheme can be designed.

[0121] In this embodiment, the basic energy supply model is obtained as follows: based on a preset sucking state (e.g., sucking for 2 seconds and stopping for 8 seconds), different energy supplies are given, and multiple users rate the energy supply. The corresponding energy data that multiple users consider to have good taste is found, and the basic energy supply model is obtained.

[0122] It should be noted that energy supply control is equivalent to power control (energy is the integral of power over time), which is particularly suitable for heated non-combustible aerosol generators that use infrared heating. The energy supply is affected by the power amplitude, duty cycle, and frequency. With the frequency remaining constant, energy can be regulated by adjusting the power amplitude and duty cycle. Furthermore, different amplitudes and duty cycles affect the ratio of heat radiation to heat conduction. The ratio of heat radiation to heat conduction supplied to the aerosol generating matrix can be adjusted according to the characteristics of the aerosol generating matrix to achieve a better taste. In addition, the optimal basic energy supply model can be found by combining user evaluations.

[0123] In some embodiments, detecting suction includes: acquiring the temperature of the heating element and determining whether suction has occurred based on changes in the temperature of the heating element, for example, if the temperature increases, it indicates that suction has occurred.

[0124] Accordingly, the current aspiration duration and the current aspiration interval duration are obtained, specifically including: obtaining the current aspiration duration and the current aspiration interval duration based on the relationship between the current heating element temperature and time, for example, aspiration for 2 seconds and pause for 3 seconds. It should be noted that the aspiration for 2 seconds and pause for 3 seconds here is only an example and is not intended to limit this application, and the aspiration for 2 seconds refers to a single aspiration lasting 2 seconds.

[0125] In some embodiments, the preset basic energy supply model is a preset output power versus time curve, which is determined based on a preset pumping state (e.g., pumping for 2 seconds and stopping for 8 seconds). The basic pumping duration and basic pumping interval can be obtained through the preset output power versus time relationship. Increasing the energy value means increasing the output power. It should be noted that the 2-second pumping and 8-second stopping scenario is merely an example and is not intended to limit this application.

[0126] In the preset suction state or the current suction interval is less than or equal to the basic suction interval, the preset basic energy supply model can ensure that the temperature of the aerosol generation matrix does not exceed the temperature required for medium combustion, and that the aerosol generation matrix is ​​heated just enough to emit a specific odor.

[0127] By implementing this invention, the following beneficial effects are achieved:

[0128] Upon receiving a start command, this invention detects that the heated non-combustible aerosol generating device is in a hot-engine state and determines that the number of continuously heated aerosol generating substrates has reached a preset threshold. In this way, it stops supplying energy to the heating element, thereby ensuring that the temperature of the aerosol generating substrates does not exceed the temperature required for the combustion of the medium when multiple aerosol generating substrates are continuously heated, reducing safety risks and improving the user's suction experience.
