Description

Technical Field

[0001] The present invention relates to the technical field of heating control, and particularly to a temperature control method, apparatus and computer-readable storage medium. Background Art

[0002] Currently, most heated aerosol generating devices use resistance, infrared or electromagnetic heating. Such aerosol generating devices with this heating method include at least one heating element. The device provides power to control the temperature of the heating element, and the heat energy is transferred to the aerosol matrix by means of contact heat transfer so that it reaches the temperature for continuously generating aerosol. However, there is a temperature difference between the heating element and the aerosol matrix, and the coking reaction causes pollution of the heating element and is not easy to clean, affecting the smoking taste of the aerosol.

[0003] In the related art, a microwave heating appliance is proposed, which uses a 1 / 4 wavelength microwave resonator to send microwave energy into the interior of the aerosol matrix. However, currently, after the heating program of the microwave heating appliance is started, it takes a relatively long time for preheating; moreover, due to continuous heating of the microwave heating appliance, it is easy to cause the aerosol generating article to be continuously above the aerosol generating temperature line for a long time, and the aerosol is continuously generated. There are obvious differences in the aerosol components and contents in the first few puffs and the last few puffs smoked by the user, resulting in a large difference in the smoking taste.

[0057] Embodiment:

[0058] Please refer to Figure 1, an embodiment of the present invention provides a temperature control method, which is applied to an aerosol generating device. The aerosol generating device includes a microwave heating component, and the microwave heating component is used to emit microwaves when powered on. The microwaves are coupled to an aerosol generating article in the aerosol generating device and generate heat, thereby heating the aerosol generating article to generate aerosol. The temperature control method includes the following steps:

[0059] Step S11, obtain the actual stage in the current heating control cycle.

[0060] Specifically, the aerosol generating device is provided with a plurality of heating control cycles to heat an aerosol generating article. Each heating control cycle includes a first stage, a second stage, and a third stage. The start time of the second stage is the end time of the first stage, and the start time of the third stage is the end time of the second stage.

[0061] It should be understood that the first stage is the starting stage of the heating control cycle, the second stage is the middle stage of the heating control cycle, and the third stage is the end stage of the heating control cycle.

[0062] Step S12, match the power value corresponding to the actual stage from the database.

[0063] Specifically, the power values corresponding to the first stage, the second stage, and the third stage of the heating control cycle are different. The database contains the power values corresponding to each stage, and the power value parameters in the database have a one-to-one mapping relationship with each stage of the heating control cycle. Among them, the first preset power value corresponding to the first stage is greater than the second preset power value corresponding to the second stage. Both the first preset power value and the second preset power value are greater than the preset power threshold, and the microwave heating component can heat the aerosol generating article to generate aerosol when powered with the power of the preset power threshold. The power value corresponding to the third stage is the third preset power value, and the third preset power value is less than the second preset power value.

[0064] It should be noted that the first preset power value and the second preset power value may or may not be associated with the time of the corresponding stage. When the first preset power value is associated with the time of the first stage, the magnitude of the first preset power value will change with time. For example, the first preset power value in the first half of the execution of the first stage is greater than that in the second half; the same is true for the second preset power value. When the first preset power value is not associated with the time of the first stage, the magnitude of the first preset power value in the first stage is constant; the same is true for the second preset power value. The third preset power value can be 0 or not 0.

[0065] It should be understood that when the first preset power value and the second preset power value are set to be associated with the moment of the corresponding stage, it is conducive to achieving more precise temperature control; when the first preset power value and the second preset power value are set to be unassociated with the moment of the corresponding stage, the control difficulty can be reduced.

[0066] Step S13: supplying power to the microwave heating component according to the corresponding power value at the actual stage.

[0067] Specifically, in the first stage, a power of a first preset power value is provided to the microwave heating component to increase the temperature of the aerosol generating product from the initial temperature to the first temperature; wherein the first preset power value is relatively large, and the power magnitude is in a positive linear relationship with the microwave power emitted by the microwave heating component, that is, the greater the power, the greater the microwave power emitted by the microwave heating component, so that the aerosol generating product can quickly reach the first temperature in the first stage, thereby realizing rapid generation of aerosol.

[0068] In the second stage, a power of a second preset power value is provided to the microwave heating component to keep the temperature of the aerosol generating product at a second temperature; wherein, since the second preset power value is less than the first preset power value, the second temperature is less than the first temperature, and since the aerosol generating product is kept at the second temperature in the second stage, continuous generation of aerosol can be ensured during the inhalation process.

[0069] In the third stage, a third preset power value is provided to the microwave heating assembly to cool the temperature of the aerosol-generating article to a third temperature.

[0070] It should be noted that the first stage and the second stage together constitute one puff, and the third stage is a puff interval. When a power greater than a preset power threshold is introduced into the microwave heating component, the aerosol-generating product can be heated to generate an aerosol, and the first preset power value and the second preset power value are both greater than the preset power threshold, so that the aerosol-generating product is heated between the first temperature and the second temperature to generate an aerosol, that is, aerosols are generated in both the first stage and the second stage. When the temperature of the aerosol-generating product is greater than the first temperature, the aerosol-generating product may generate aerosol products that are harmful to health.

[0071] In this embodiment, by providing the microwave heating component with a first preset power value to increase the temperature of the aerosol generating product from the initial temperature to the first temperature in the first stage, the aerosol generating product can quickly reach the temperature for generating aerosol, and achieve rapid inhalation; in the second stage, the microwave heating component is provided with a second preset power value to keep the temperature of the aerosol generating product at the second temperature, and the aerosol generating product can continuously generate aerosol at the second temperature, thereby ensuring that the aerosol generating product does not burn or generate aerosol products that are harmful to health at high temperature during the inhalation process, and also ensuring that the aerosol generating product is continuously heated to generate a certain amount of aerosol, thereby ensuring the consistency of the inhalation taste and release of the aerosol. Moreover, the microwave heating component is not powered during the inhalation interval, which can avoid power waste.

[0072] It should be noted that since the temperature control method provided in this embodiment is applied to an aerosol generating device using microwave heating, compared with the aerosol generating product generated by a heating element in the prior art, no preheating is required before puffing and aerosol can be generated quickly, and no condensation of evaporated gas will occur during the puff interval, thereby avoiding heating and contamination of the device, and preventing the device from being easily damaged and reducing the taste of the puff.

[0073] In one embodiment, before step S11, the following steps are further performed:

[0074] Step S10, determining whether the current heating control cycle is a valid heating control cycle; if it is a valid heating control cycle, executing the next step.

[0075] Specifically, different aerosol generating products have different possible puff times, and the possible puff times are set according to the atomization amount and shape of the aerosol generating product. The possible puff times are generally between 12 and 14. The aerosol generating product will not generate aerosol if puffs are performed after the puffs exceed the possible puff times. Therefore, the total number of effective heating control cycles for heating the aerosol generating product to generate aerosol is the same as the possible puff times. For example, if the possible puff times of type A aerosol generating product is 12, the corresponding total number of effective heating control cycles is 12. If the possible puff times of type B aerosol generating product is 14, the corresponding total number of effective heating control cycles is 14.

[0076] It should be noted that if the current heating control cycle is a valid heating control cycle, it indicates that heating the aerosol generating product within the heating control cycle can generate aerosol, and thus the heating control cycle is executed; if the current heating control cycle is not a valid heating control cycle, it indicates that heating the aerosol generating product within the heating control cycle will not generate aerosol, and thus the heating is stopped; at the same time, the aerosol generating device is controlled to issue a prompt to replace the aerosol generating product, thereby reminding the user to replace the aerosol generating product in time to avoid wasting electricity to heat the aerosol generating product again; moreover, it can also avoid the inability to inhale aerosol during puffing, thereby improving the puffing experience. The following are examples:

[0077] The total number of effective heating control cycles is 14. When it is determined that the current heating control cycle is the fifth, the heating control cycle is executed; when it is determined that the current heating control cycle is the fifteenth, a prompt to replace the aerosol generating product is issued, wherein the prompt can be a light prompt or a sound prompt, the light prompt can be a flashing red light, and the sound prompt can be a beep.

[0078] In some embodiments, the above step S10 further includes the following steps:

[0079] Step S101, obtaining the total number of effective heating control cycles corresponding to the aerosol generating product heated by the aerosol generating device.

[0080] Specifically, the total number of effective heating control cycles of the aerosol generating product can be obtained through user input or by detecting the aerosol generating product. For example, three buttons A, B, and C can be set on the aerosol generating product. When button A is triggered, the total number of effective heating control cycles obtained is 12, when button B is triggered, the total number of effective heating control cycles obtained is 13, and when button C is triggered, the total number of effective heating control cycles obtained is 14; alternatively, multiple infrared detection sensors are set on the aerosol generating device, and the aerosol generating device is provided with a trigger component that cooperates with the infrared detection sensor, and the position of the trigger component on different types of aerosol generating products is different, so that it can be detected by infrared detection sensors at different positions on the aerosol generating device, thereby obtaining the total number of effective heating control cycles of the corresponding aerosol generating product.

[0081] Step S102: When the aerosol generating device is in working state, the heating control cycle is counted to obtain the actual cumulative number of heating control cycles.

[0082] Step S103: compare the actual cumulative number of heating control cycles with the total number of effective heating control cycles.

[0083] Step S104: Determine whether the current heating control cycle is a valid heating control cycle according to the comparison result; wherein, if the cumulative number of actual heating control cycles is less than or equal to the total number of valid heating control cycles, it is determined that the current heating control cycle is a valid heating control cycle.

[0084] It should be noted that when the cumulative number of actual heating control cycles is greater than the total number of valid heating control cycles, it is determined that the current heating control cycle is an invalid heating control cycle, and at this time, a prompt to replace the aerosol generating article is issued.

[0085] It should be understood that in some other embodiments, the step of determining whether the current heating control cycle is a valid heating control cycle can also be determined by detecting the mass or volume of the aerosol generating article; for example, when the mass of the aerosol generating article is within the preset standard range, it is determined that the current heating control cycle is a valid heating control cycle; when the mass of the aerosol generating article is not within the preset standard range, a prompt to replace the aerosol generating article is issued.

[0086] In one embodiment, step S11 includes the following steps:

[0087] Step S110: When receiving a heating control signal, correspondingly determine the actual stage of the current heating control cycle according to the signal type of the heating control signal.

[0088] Specifically, when receiving a start heating control signal, it is correspondingly determined that the current heating control cycle is in the first stage; when receiving a continuous heating control signal, it is correspondingly determined that the current heating control cycle is in the second stage; when receiving a stop heating control signal, it is correspondingly determined that the current heating control cycle is in the third stage.

[0089] In the first stage, a first preset power value that raises the temperature of the aerosol generating article from the initial temperature to the first temperature is provided to the microwave heating component. The first temperature is between 200°C and 350°C, such as 200°C, 220°C, 250°C, 300°C, 320°C, 350°C, etc. The value range of the first temperature is determined by the material of the aerosol generating article. The first stage of the heating control cycle is a process of quickly heating the aerosol generating article to generate aerosol, and the duration of the first stage can be between 0.01s and 5s, such as 0.01s, 0.6s, 1s, 2.8s, 4s, and 5s, etc.

[0090] In the second stage, a second preset power value for maintaining the temperature of the aerosol-generating article at a second temperature is provided to the microwave heating assembly. The second temperature is between 100°C and 350°C. For example, the second temperature can be 100°C, 140°C, 200°C, 260°C, 300°C, 350°C, etc. The first temperature is greater than the second temperature. For example, when the first temperature is 200°C, the second temperature is 100°C.

[0091] In the third stage, a power of a third preset power value is provided to the microwave heating assembly to cool the temperature of the aerosol-generating article to a third temperature. Among them, the third temperature can be greater than the initial temperature or equal to the initial temperature. In actual application scenarios, the magnitude of the third preset power value is related to the working state of the aerosol-generating device, as follows:

[0092] Step S14: In the third stage, obtain the working state of the aerosol-generating device.

[0093] Specifically, the working state includes a heat preservation state and a standby state. After a user completes one puff, the user may immediately perform the next puff, or may perform the next puff after a short interval, or may perform the next puff after a long interval. Among them, when the user immediately performs the next puff and performs the next puff after a long interval after completing one puff, it is in the standby state. When the user performs the next puff after a short interval, it is in the heat preservation state. For example, the user immediately performs the next puff within 1 s after the previous puff; performs the next puff after an interval of 20 s (short interval), such as when the user has a sudden cough and then performs the next puff; performs the next puff after an interval of three minutes (long interval), such as when the user enters the elevator and then performs the next puff after getting out of the elevator.

[0094] Step S15: Determine whether the power supply condition of the microwave heating assembly is satisfied according to the working state. If the working state is the heat preservation state, the power supply condition is satisfied, and then a power of a third preset power value is provided to the microwave heating assembly; if the working state is the standby state, the power supply condition is not satisfied, and then a power value of 0 is provided to the microwave heating assembly.

[0095] Specifically, the third preset power value is less than the second preset power value, so that the third temperature is less than the second temperature, and to avoid generating aerosol by heating the aerosol-generating article in the third stage. When the working state is the heat preservation state, the third temperature is greater than the initial temperature, so that the time required to increase from the third temperature to the first temperature is shorter than the time required to increase from the initial temperature to the first temperature. Therefore, when the aerosol-generating device is in the heat preservation state, aerosol can be generated more quickly when the aerosol-generating device starts to puff. When the working state is the standby state, continue to control the microwave heating assembly to be powered off, and at this time the third temperature will cool to the initial temperature, so that electricity can be saved when the puff interval is too long.

[0096] In some embodiments, the control detection device detects the user's puffing behavior data; if the user's puffing state is determined to be the start puffing state according to the user's puffing behavior data, a start heating control signal is generated; if the user's puffing state is determined to be the stop puffing state according to the user's puffing behavior data, a stop heating control signal is generated. The real-time heating temperature of the aerosol generating product is detected; the real-time heating temperature is compared with the first preset temperature; when the real-time heating temperature is equal to the first preset temperature, a continuous heating control signal is generated.

[0097] Specifically, the detection device can be a trigger or a sensor. The trigger can be a button, and a start heating control signal or a stop heating control signal is generated by triggering different buttons. For example, triggering button A generates a start heating control signal, and triggering button B generates a stop heating control signal; or, a start heating control signal or a stop heating control signal is generated by different button triggering times. For example, a start heating control signal is generated when the button is triggered once, and a stop heating control signal is generated when it is triggered twice. The sensor can be a position sensor, a pressure sensor, and a combination of multiple sensors. For example, when the sensor is a position sensor, the position of the position sensor changes when the puffing starts and stops, and the start heating control signal is generated when the distance between the position sensor and the position sensor reaches a preset distance threshold before the puffing starts, and the stop heating control signal is generated when the distance between the position sensor and the position sensor does not reach the preset distance threshold when the puffing stops. A temperature sensor can be used to detect the real-time temperature of the aerosol generating product, and a microwave measurement method can also be used to detect the real-time temperature of the aerosol generating product. Wherein, when the real-time heating temperature is less than the first preset temperature, the first stage is continued.

[0098] In some embodiments, the generation of the stop heating control signal may also be: in the execution process of the second stage, the executed heating time is detected in real time; when the executed heating time reaches a preset time threshold, the stop heating control signal is generated. For example, the preset time threshold may be 3 seconds, and when the executed heating time reaches 3 seconds, the stop heating control signal is generated; when the executed heating time does not reach 3 seconds, the second stage is continued.

[0099] See also Figure 2 , Figure 2 The detailed flow chart of the temperature control method provided by the embodiment of the present invention includes the following steps:

[0100] Step S20, controlling the detection device to detect the user's puffing behavior data; if it is determined according to the user's puffing behavior data that the user's puffing state is the start puffing state, then generating a heating start control signal.

[0101] Step S21: When a start heating control signal is received, correspondingly determine that the current heating control cycle is in the first stage.

[0102] Step S22: Match the first preset power value corresponding to the first stage from the database.

[0103] Step S23: Provide power of the first preset power value to the microwave heating component in the first stage.

[0104] Step S24: Detect the real-time heating temperature of the aerosol generating article; compare the real-time heating temperature with the first preset temperature; when the real-time heating temperature is equal to the first preset temperature, generate a continuous heating control signal.

[0105] Step S25: When a continuous heating control signal is received, correspondingly determine that the current heating control cycle is in the second stage.

[0106] Step S26: Match the second preset power value corresponding to the second stage from the database.

[0107] Step S27: Provide power of the second preset power value to the microwave heating component in the second stage.

[0108] Step S28: During the execution of the second stage, detect the elapsed heating duration in real time; when the elapsed heating duration reaches the preset duration threshold, generate a stop heating control signal.

[0109] Step S29: When a stop heating control signal is received, correspondingly determine that the current heating control cycle is in the third stage.

[0110] Step S30: Match the third preset power value corresponding to the third stage from the database.

[0111] Step S31: Provide power of the third preset power value to the microwave heating component in the third stage.

[0112] Please refer to Figure 3 , Figure 3 which is a schematic diagram of the temperature curve of the aerosol generating article provided by the embodiment of the present invention, wherein the abscissa is time and the ordinate is temperature; Figure 3 In any heating control cycle, the aerosol generating article is in a standby state in the third stage. It should be noted that at the end of the first stage, since the user's suction will take away some heat, resulting in a temperature drop, the second preset power provided to the microwave heating component in the second stage enables the aerosol generating article to maintain at the second temperature.

[0113] Please refer to Figure 4 and Figure 5This embodiment provides an aerosol generating device, including a power supply 1, a microwave heating component, and a controller 3. The microwave heating component is electrically connected to the power supply 1; the microwave heating component is used to accommodate the aerosol generating product, and emit microwaves to heat the aerosol generating product when powered on; the controller 3 is electrically connected to the power supply 1 and the microwave heating component, and the controller 3 uses the temperature control method as described above to control the heating temperature of the aerosol generating product, which can not only achieve rapid aerosol suction, but also ensure that the aerosol generating product does not burn or produce aerosol products that are harmful to health at high temperatures during the suction process. At the same time, it can also ensure that the aerosol generating product is continuously heated to generate a certain amount of aerosol, improve the uniformity of the temperature field, and ensure the consistency of the aerosol inhalation taste and release.

[0114] Specifically, the microwave heating assembly includes a radio frequency source 2, which can emit microwaves (electromagnetic waves) when powered on. The radio frequency source 2 includes a radio frequency oscillation circuit, a radio frequency amplification circuit, a radio frequency detection circuit, a radio frequency transmission line, etc. The controller 3 adjusts the working cycle of each of the above circuits to emit high-frequency signals of different frequencies and intensities, thereby controlling the power provided by the radio frequency source 2, and further controlling the heating temperature of the aerosol-generating product. Among them, the power is linearly related to the power of the microwaves emitted by the radio frequency source 2, and the greater the power, the greater the power of the microwaves emitted by the radio frequency source 2.

[0115] See also Figure 4 In some embodiments, the microwave heating assembly further includes a resonator 4, and the aerosol generating device further includes a probe 5 connected to the RF source 2 and extending into the resonator 4, a temperature sensor disposed at one end of the probe 5 away from the RF source 2 and electrically connected to the controller 3, and a position sensor 6 electrically connected to the controller 3. The temperature sensor may be a thermocouple (or an infrared sensor, a thermistor, etc.) disposed on the probe 5, and the temperature of the aerosol generating product 9 is measured by the thermistor. The position sensor 6 senses the user's puffing characteristic action by detecting the position change, so as to transmit a start heating control signal or a stop heating control signal to the controller 3. The aerosol generating product 9 may be a cylinder, the outer diameter of the cylinder may be 7.2 mm, and the length may be 12 mm. When the aerosol generating product 9 is inserted into the resonant cavity of the resonator 4, the probe 5 is inserted into the interior of the aerosol generating product 9.

[0116] Specifically, when the position sensor 6 detects a characteristic action before suction, the position sensor 6 transmits a start heating control signal to the controller 3. The controller 3 executes the first stage of the corresponding heating control cycle according to the received start heating control signal. The controller 3 controls the power supply 1 to provide a power of a first preset power value to the radio frequency source 2, so that the temperature of the aerosol-generating article starts to rise from the initial temperature. When the temperature of the aerosol-generating article 9 detected by the temperature measuring sensor rises to the first temperature, the controller 3 executes the second stage of the corresponding heating control cycle. At this time, the controller 3 controls the power supply 1 to provide a power of a second preset power value to the radio frequency source 2, so that the temperature of the aerosol-generating article 9 drops from the first temperature to the second temperature and remains at the second temperature. When the position sensor 6 detects a characteristic action at the stop of suction, the position sensor 6 transmits a stop heating control signal to the controller 3. The controller 3 executes the third stage of the corresponding heating control cycle according to the received stop heating control signal. After the third stage is completed, the corresponding heating control cycle is completed, and it waits for the next heating control cycle.

[0117] Please refer to Figure 5 , in some embodiments, the microwave heating assembly further includes a heating antenna 7 electrically connected to the controller 3. The aerosol-generating device further includes a detection assembly for detecting a characteristic action before suction. Among them, the detection assembly can be a pressure sensor 8. The pressure sensor 8 senses the user's suction characteristic action by detecting the pressure change, so as to generate a start heating control signal or a stop heating control signal. The aerosol-generating article 9 can be spherical with a diameter of 3 mm. The temperature of the aerosol-generating article 9 is calculated from the radio frequency monitoring reflection S11 parameter, phase and resonance frequency, that is, the microwave measurement method is adopted.

[0118] Specifically, when the pressure sensor 8 detects a characteristic action before suction, the pressure sensor 8 transmits a start heating control signal to the controller 3. The controller 3 executes the first stage of the corresponding heating control cycle according to the received start heating control signal. The controller 3 controls the power supply 1 to provide a first preset power value, so that the temperature of the aerosol-generating article 9 starts to rise from the initial temperature. When the temperature of the aerosol-generating article detected by the microwave measurement method rises to the first temperature, the controller 3 executes the second stage of the corresponding heating control cycle. At this time, the controller 3 controls the power supply 1 to provide a second preset power value, so that the temperature of the aerosol-generating article 9 drops from the first temperature to the second temperature and remains at the second temperature. After the second stage is executed for a preset duration, a stop heating control signal is transmitted to the controller 3. The controller 3 executes the third stage of the corresponding heating control cycle according to the received stop heating control signal. After the third stage is completed, the corresponding heating control cycle is completed, and it waits for the next heating control cycle.

[0119] It should be noted that the microwave heating assembly can be designed to automatically and continuously insert and remove the aerosol-generating article 9. The aerosol-generating article 9 can also be in the form of a strip, filament, cake, etc., so as to be automatically and continuously fed into the microwave heating assembly.
