Description

Technical Field

[0001] The present application relates to the field of temperature control technology, and in particular to an aerosol generating device, a temperature control method, an electronic device and a storage medium. Background Art

[0002] Aerosol refers to a gaseous dispersion system composed of solid or liquid particles suspended in a gas medium. Common aerosols in life include clouds, fog, and dust in the sky, and smoke formed by unburned fuel in boilers and various engines used in industry and transportation.

[0003] The production of aerosols can meet the needs of many fields in human society. In the process of producing aerosols, the control of heating temperature is crucial. Accurate temperature control can ensure that the aerosol generating matrix releases volatile compounds at the optimal temperature and optimize energy use. Existing aerosol generating devices mostly use contact temperature measurement, that is, the temperature is measured by the temperature measuring device in direct contact with the aerosol generating matrix. Although the temperature measuring device can directly obtain the temperature of the aerosol generating matrix under direct contact, in actual long-term application, contact temperature measurement has the problem of reduced accuracy due to the formation of condensate on the surface of the temperature measuring device caused by contact temperature measurement, and the repeated heating and cooling process shortens the life of the temperature measuring device and reduces the accuracy.

In addition, compared with contact temperature measurement, the life of the temperature measuring device can be extended.

Therefore, the protection scope of the present application should be based on the protection scope of the claims.

[0069] The temperature measuring elements of the aerosol heating devices currently on the market usually use direct contact to measure the temperature of the object to be measured. The mainstream temperature measuring elements are thermocouples, NTC, PTC, etc., and their fixing methods include welding, attachment, etc., embedded inside the heating element or close to the surface of the heating element. This contact temperature measurement method has the following disadvantages: the additional fixed temperature measuring device will increase the complexity of the overall structure. Whether it is welding or gapless attachment, the manufacturing process is high. If the manufacturing process does not meet the standards, it will not only affect the yield of the product, but also affect the effect of temperature measurement. In addition, aerosol condensate will be deposited on the surface of the heating element during the periodic heating and cooling of the aerosol-generating product, which will also affect the accuracy of temperature measurement. On the other hand, the temperature measuring device is easily affected by the life of the sensing element and the stability of welding due to direct contact temperature measurement. Repeated high-temperature-low-temperature cycles will lead to a decrease in contact quality, which in turn leads to a decrease in temperature measurement accuracy.

[0070] In view of the above problems, the present application provides an aerosol generating device, which includes: a temperature measuring device for detecting the temperature of the heated body to obtain the measured temperature of the heated body; and a spacing structure for supporting the heated body and the temperature measuring device, and forming a gap between the temperature measuring device and the heated body. This aerosol generating device realizes non-contact temperature measurement by arranging the temperature measuring device on the spacing structure to form a gap between the temperature measuring device and the heated body.

[0071] For ease of understanding, the aerosol generating device provided in the present application is specifically introduced below with reference to the accompanying drawings.

[0072] Figure 1 A schematic diagram of the structure of an aerosol generating device provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the aerosol generating device 100 includes: a temperature measuring device 101 and a spacing structure 102 .

[0073] The temperature measuring device 101 is used to detect the temperature of the heated object and obtain the measured temperature of the heated object.

[0074] In some embodiments, the temperature measuring device 101 includes a sensor for measuring temperature.

[0075] Exemplarily, the sensor for measuring temperature may be, but is not limited to, at least one of the following: a thermocouple temperature sensor, a thermal resistor temperature sensor, a semiconductor temperature sensor, an infrared temperature sensor, and an optical fiber temperature sensor.

[0076] The spacing structure 102 is used to support the heated object and the temperature measuring device, and to form a gap between the temperature measuring device and the heated object.

[0077] Exemplarily, the spacing structure 102 may be, but is not limited to, at least one of the following: a bracket-type spacing structure, a heat-insulating material.

[0078] In some embodiments, the aerosol generating device 100 further includes: a heating device 103 .

[0079] The heating device 103 is used to heat the object to be heated.

[0080] In some embodiments, the heating device 103 may be, but is not limited to, at least one of the following: a plug-in heating component, an induction heating component, an airflow heating component, and the present application does not limit this. Figure 1 A possible induction heating component (induction coil) is shown in FIG.

[0081] In some embodiments, the aerosol generating device 100 further comprises: a temperature control device ( Figure 1 The temperature control device is connected to the temperature measuring device 101 and the heating device 103 respectively.

[0082] The temperature control device is configured to obtain the measured temperature of the heated body and control the working state of the heating device based on the measured temperature of the heated body.

[0083] In some embodiments, the temperature control device determines the actual temperature of the heated body based on the measured temperature of the heated body, and controls the working state of the heating device based on the actual temperature of the heated body.

[0084] In some embodiments, the temperature control device determines the actual temperature of the heated body by determining the temperature difference between the temperature measuring device and the heated body due to heat conduction delay, and then determines the actual temperature of the heated body based on the measured temperature of the heated body and the temperature difference.

[0085] In one possible implementation, the temperature control device determines the temperature difference between the temperature measuring device and the heated body due to heat conduction delay based on the measured temperature of the heated body, the heat conductivity coefficient, the distance between the temperature measuring device and the heated body, and the heat transfer delay time.

[0086] Exemplarily, the temperature control device establishes a function of the measured temperature of the heated body in relation to time, and then substitutes the heat conduction coefficient and the distance between the temperature measuring device and the heated body into the heat conduction related equation, thereby determining the temperature difference between the temperature measuring device and the heated body caused by the heat conduction delay.

[0087] In another possible implementation, the temperature control device inputs the measured temperature of the heated body into a temperature compensation model to obtain the actual temperature of the heated body. The temperature compensation model is used to perform temperature compensation on the input measured temperature and output the actual temperature corresponding to the measured temperature.

[0088] In some embodiments, the temperature compensation model is trained based on training samples, wherein the training samples include sample data and sample labels, the sample data is the historical measured temperature of the heated object, and the sample label is the historical actual temperature of the heated object.

[0089] In some embodiments, the temperature control device determines the actual temperature of the heated body based on the measured temperature of the heated body, and controls the working state of the heating device based on the actual temperature of the heated body. This can be specifically implemented as follows: correcting the actual temperature of the heated body to obtain the corrected actual temperature, and controlling the working state of the heating device based on the corrected actual temperature.

[0090] In some embodiments, the temperature control device uses an extended Kalman filter algorithm to correct the actual temperature of the heated body to obtain a corrected actual temperature.

[0091] In some embodiments, the temperature control device is used to control the heating device to be in a heating working state when the actual temperature of the heated body is lower than a preset temperature, and to control the heating device to stop heating when the actual temperature of the heated body is greater than or equal to the preset temperature.

[0092] In some embodiments, the temperature control device is further used to adjust the heating rate of the heating device based on the difference between the actual temperature of the heated body and the preset temperature when the heating device is in a heating working state.

[0093] Exemplarily, when the actual temperature deviates from the preset temperature by a large margin, the heating rate of the heating device is increased, and when the actual temperature deviates from the preset temperature by a small margin, the heating rate of the heating device is decreased.

[0094] In some embodiments, the temperature control device determines the adjustment amount of the heating rate of the heating device based on the difference between the actual temperature of the heated body and the preset temperature by adopting fuzzy PID control, and then adjusts the heating rate of the heating device based on the adjustment amount.

[0095] It can be understood that the aerosol generating device involved in the present application adopts a temperature measurement method in which there is a gap between the temperature measuring device and the heated body, that is, a non-contact temperature measurement method, which reduces the installation difficulty and installation cost of the temperature measuring device, and avoids the problem in the prior art that due to the direct contact between the temperature measuring device and the heated body, aerosol condensate is formed on the surface of the temperature measuring device during the periodic heating process, thereby affecting the temperature measurement accuracy.

[0096] It should be noted that the above-mentioned system structure and renderings are intended to more clearly illustrate the technical solution of the embodiment of the present application, and do not constitute a limitation on the technical solution provided by the embodiment of the present application. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present application is also applicable to similar technical problems.

[0097] The temperature control method provided in the present application is described in detail below with reference to the accompanying drawings.

[0098] Figure 2 A flow chart of a temperature control method provided in an embodiment of the present application. The temperature control method provided in an embodiment of the present application is applied to Figure 1 The temperature control device in the provided aerosol generating device, such as Figure 2 As shown, the method includes the following steps S101-S102:

[0099] S101, obtaining the measured temperature of the heated object.

[0100] Among them, the measured temperature of the heated body is obtained by a temperature measuring device detecting the temperature of the heated body, and there is a spacing structure between the temperature measuring device and the heated body; the spacing structure is used to support the heated body and the temperature measuring device, and to form a gap between the temperature measuring device and the heated body.

[0101] In some embodiments, the temperature directly sensed by the temperature sensing element in the temperature measuring device is used as the measured temperature of the heated body, wherein the distance between the position of the temperature sensing element and the surface of the heated body is less than or equal to a preset distance.

[0102] It should be understood that in the actual heat conduction process, the factors causing heat loss are complex, that is, the factors causing temperature measurement errors are complex. Therefore, by placing the temperature sensing element at a distance less than or equal to the preset distance from the surface of the heated body, the heat can reach the temperature sensing element in a shorter time and a shorter distance, which can reduce the temperature measurement error caused by the non-contact temperature measurement method to a certain extent.

[0103] In some embodiments, the preset distance can be determined based on the thermal conductivity of the spacing structure, the thermal conductivity of the heated object, etc. The present application does not limit the preset distance.

[0104] S102: Control the working state of the heating device based on the measured temperature of the heated object.

[0105] It can be understood that the temperature control method provided in the present application realizes controlling the temperature of the heated body when there is a gap between the temperature measuring device and the heated body, that is, in a non-contact temperature measurement mode.

[0106] Since there is a gap between the temperature measuring device and the heated object, there is heat loss in the process of heat transfer from the heated object to the temperature measuring device, resulting in a difference between the measured temperature of the heated object and the actual temperature of the heated object. Figure 3 As shown, the above S102 can be specifically implemented as the following steps S201-S202:

[0107] S201. Determine the actual temperature of the heated object based on the measured temperature of the heated object.

[0108] The process of determining the actual temperature of the heated body based on the measured temperature of the heated body is introduced in steps S401-S402 and S501 below, and will not be repeated here.

[0109] S202: Control the working state of the heating device based on the actual temperature of the heated object.

[0110] Among them, there are the following two situations for controlling the working state of the heating device.

[0111] Case 1: When the actual temperature of the heated body is lower than the preset temperature, the heating device is controlled to be in a heating working state.

[0112] In some embodiments, for an aerosol generating device, the heated body refers to an aerosol generating substrate, and the preset temperature refers to the temperature at which the aerosol generating substrate releases the aerosol. Exemplarily, the aerosol generating substrate can be glycerin, propylene glycol, aromatic plants, etc.

[0113] Further, when the heating device is in a heating working state, the heating rate of the heating device is adjusted based on the difference between the actual temperature of the heated body and the preset temperature.

[0114] In some embodiments, the above S202 can be implemented as follows: using fuzzy PID control, based on the difference between the actual temperature of the heated body and the preset temperature, determining the adjustment amount of the heating rate of the heating device, and adjusting the heating rate of the heating device based on the adjustment amount.

[0115] In some embodiments, the heating power of the heating device is determined based on the adjustment amount, and the heating rate of the heating device is adjusted by adjusting the heating power of the heating device.

[0116] Exemplarily, the use of fuzzy PID control to determine the adjustment amount of the heating rate of the heating device has the following process: based on the actual temperature of the heated body and the preset temperature, the temperature deviation and the deviation change rate are calculated, and then the calculated temperature deviation and the deviation change rate are fuzzy processed by a preset membership function, and then the fuzzified temperature deviation and the deviation change rate are substituted into the fuzzy rule base, and through the fuzzy reasoning method, such as the Mamdani reasoning method, the fuzzy values ​​of the PID parameter correction amounts ΔKp, ΔKi, and ΔKd are calculated, and then the fuzzy values ​​of the PID parameter correction amounts ΔKp, ΔKi, and ΔKd are converted into specific numerical values, which are added to the original PID control parameters Kp, Ki, and Kd respectively to obtain new PID parameter values, and finally the new PID parameter values ​​are substituted into the PID control algorithm formula to calculate the control amount, that is, to determine the adjustment amount of the heating rate of the heating device.

[0117] It should be understood that temperature control often has complex characteristics such as nonlinearity, time variation, and hysteresis. Fuzzy PID control can flexibly adjust PID parameters according to temperature deviation and deviation change rate. For example, when the actual temperature deviates from the preset temperature by a large amount, the proportional gain is increased to speed up the response speed, that is, to increase the heating rate of the heating device. When the actual temperature deviates from the preset temperature by a small amount, the proportional gain is reduced and / or the integral effect is increased, that is, to slow down the heating rate of the heating device. By adjusting the heating rate of the heating device through fuzzy PID control, it is possible to quickly respond to changes in temperature deviation and adjust the control strategy in a timely manner, thereby ensuring the accuracy and control rate of temperature control.

[0118] Case 2: When the actual temperature of the heated body is greater than or equal to the preset temperature, the heating device is controlled to stop heating.

[0119] In some embodiments, since the heating coil has residual heat after stopping heating, the heating of the heated object will continue for a period of time. Therefore, the heating device can be controlled to stop heating when the actual temperature of the heated object is about to reach the preset temperature or the difference between the actual temperature of the heated object and the preset temperature is less than the preset value.

[0120] It can be understood that determining the actual temperature of the heated body based on the measured temperature of the heated body, and then controlling the working state of the heating device based on the actual temperature of the heated body can compensate for the temperature deviation caused by heat loss and improve the accuracy of controlling the working state of the heating device.

[0121] In some embodiments, Figure 4 As shown, S202 can be specifically implemented as S301-S302:

[0122] S301, correcting the actual temperature of the heated body to obtain a corrected actual temperature.

[0123] In some embodiments, an extended Kalman filter algorithm is used to correct the actual temperature of the heated body to obtain a corrected actual temperature.

[0124] Exemplarily, the process of using the extended Kalman filter algorithm to correct the actual temperature of the heated object is as follows:

[0125] S302: Based on the corrected actual temperature, control the working state of the heating device.

[0126] It can be understood that after correction by the extended Kalman filter algorithm, the temperature error caused by interference factors (such as environmental factors, instrument errors, etc.) can be eliminated to a certain extent, the fluctuation of actual temperature can be reduced, and the accuracy and stability of temperature measurement can be improved.

[0127] The following is a detailed description of the process of determining the actual temperature of the heated body based on the measured temperature of the heated body involved in step S201.

[0128] A possible implementation is Figure 5 As shown, S201 can be specifically implemented as S401-S402:

[0129] S401, determining the temperature difference between the temperature measuring device and the heated body caused by heat conduction delay.

[0130] In some embodiments, the heat transfer delay (tt) between the temperature measuring device and the heated body is determined based on the measured temperature of the heated body, the thermal conductivity coefficient, the distance between the temperature measuring device and the heated body, and the heat transfer delay time. 0 ) is the measured temperature of the heated body at the moment.

[0131] S402: Determine the actual temperature of the heated body based on the measured temperature of the heated body and the temperature difference.

[0132] In some embodiments, the distance between the temperature measuring device and the heated body refers to the distance between the temperature measuring device and the surface of the heated body on the radial horizontal section of the heated body where the temperature measuring device is located. The actual temperature of the heated body refers to the temperature of the surface of the heated body on the radial horizontal section of the heated body where the temperature measuring device is located. In this case, the thermal conductivity coefficient includes the thermal conductivity coefficient of the spacing structure.

[0133] In some embodiments, the temperature measured by the temperature measuring device is T 0 , the temperature of the heated object is T 1 The relationship between the two is:

[0134] T 1 (t) = T 0 (t)+ΔT(t)

[0135] Where, T 1 (t) is the actual temperature of the heated body at time t, T 0 (t) is the measured temperature of the heated object at time (t), and ΔT(t) is the temperature difference. ΔT represents the temperature difference caused by the heat conduction delay effect. The value of this item is determined by factors such as the temperature of the heated object, the thermal conductivity coefficient of the spacing structure, and the distance between the temperature measuring device and the heated object. ΔT can be calculated based on the thermal conductivity coefficient of the spacing structure and the distance between the temperature measuring device and the heated object through the heat conduction equation.

[0136] In other embodiments, the distance between the temperature measuring device and the heated body refers to the distance between the temperature measuring device and the center of the cross section of the heated body on the radial horizontal section of the heated body where the temperature measuring device is located. The actual temperature of the heated body refers to the temperature of the center of the cross section of the heated body on the radial horizontal section of the heated body where the temperature measuring device is located. In this case, the value of the above ΔT is determined by factors such as the temperature of the heated object, the thermal conductivity coefficient of the spacing structure, the thermal conductivity coefficient of the heated body, and the distance between the temperature measuring device and the heated object. ΔT can be calculated by the heat conduction equation based on the thermal conductivity coefficient of the spacing structure, the thermal conductivity coefficient of the heated body, and the distance between the temperature measuring device and the heated body. Another possible implementation method, such as Figure 6 As shown, S201 can be specifically implemented as S501:

[0137] S501. Input the measured temperature of the heated body into a temperature compensation model to obtain the actual temperature of the heated body.

[0138] The temperature compensation model is used to perform temperature compensation on the input measured temperature and output the actual temperature corresponding to the measured temperature.

[0139] In some embodiments, the temperature compensation model is trained based on training samples.

[0140] The training samples include sample data and sample labels, the sample data is the historical measured temperature of the heated body, and the sample label is the historical actual temperature of the heated body.

[0141] Exemplarily, the training of the temperature compensation model has the following process:

[0142] a1. Collect historical data.

[0143] The historical data includes the historical measured temperature and the historical actual temperature of the heated body.

[0144] a2. Preprocess historical data.

[0145] In some embodiments, the collected data is cleaned and preprocessed to remove outliers and noise to ensure the accuracy and consistency of the data.

[0146] a3. Choose a suitable model.

[0147] In some embodiments, a suitable temperature compensation model can be selected according to the characteristics of the data and the complexity of the problem. Common models include linear models, polynomial models, neural network models, etc. For example, BP neural network is a commonly used nonlinear model that can handle complex temperature compensation problems.

[0148] a4. Design the model structure.

[0149] In some embodiments, designing the structure of the model includes determining the specific structure and parameters of the model.

[0150] For example, for a BP neural network, it is necessary to determine the number of nodes in the input layer, hidden layer, and output layer, as well as the activation function, etc.

[0151] a5. Train the temperature compensation model.

[0152] In some embodiments, the preprocessed historical data is input as training samples into the temperature compensation model for training, wherein the training samples include sample data and sample labels, the sample data is the historical measured temperature of the heated body, and the sample label is the historical actual temperature of the heated body.

[0153] In some embodiments, during the training process of the model, the model parameters are adjusted so that the output of the model is as close to the sample label as possible, thereby improving the accuracy of the model.

[0154] a6. Model application.

[0155] In some embodiments, the trained temperature compensation model is deployed in actual applications for real-time temperature compensation.

[0156] The temperature control detection method provided by the present application is introduced below through a complete embodiment. Figure 7 As shown, the following steps are included:

[0157] S1. Obtain the measured temperature of the heated object.

[0158] Among them, the measured temperature is obtained by a temperature measuring device detecting the temperature of the heated body, and there is a spacing structure between the temperature measuring device and the heated body; the spacing structure is used to support the heated body and the temperature measuring device, and to form a gap between the temperature measuring device and the heated body.

[0159] S2. Determine the actual temperature of the heated body based on the measured temperature of the heated body.

[0160] The process of determining the actual temperature of the heated body based on the measured temperature of the heated body is introduced in the above steps S401-S402 and S501, and will not be repeated here.

[0161] S3. Correct the actual temperature of the heated body to obtain a corrected actual temperature.

[0162] In some embodiments, an extended Kalman filter algorithm is used to correct the actual temperature of the heated object to obtain a corrected actual temperature.

[0163] Exemplarily, the process of using the extended Kalman filter algorithm to correct the actual temperature of the heated body is as follows: establish the state equation and observation equation of the temperature control system, determine the initial state and initial covariance matrix based on historical temperature data or measurement data, and then based on the initial state and initial covariance matrix, use the state equation and observation equation to predict the temperature at the current moment based on the state estimate and control input at the previous moment. After obtaining the temperature observation value at the current moment, perform an update step, including Kalman gain calculation, state update and error covariance update, and then repeat the above prediction and update steps until the filtering process is completed.

[0164] S4. Determine whether the corrected actual temperature is less than the preset temperature.

[0165] If yes, go to step S5, otherwise go to step S6.

[0166] S5. Control the heating device to be in heating working state.

[0167] S6. Control the heating device to stop heating.

[0168] S7. Determine whether the difference between the corrected actual temperature and the preset temperature is less than the preset value.

[0169] If so, go to step S8, otherwise go to step S9.

[0170] S8. Reduce the heating rate of the heating device.

[0171] S9. Increase the heating rate of the heating device.

[0172] After completing the above steps S6, S8 and S9, return to step S1.

[0173] It can be understood that the temperature control method involved in the present application takes into account that the temperature measured by non-contact measurement has a deviation between the actual temperature and the measured temperature due to temperature loss in the heat transfer process. Therefore, the actual temperature of the heated body is determined based on the measured temperature of the heated body and various related parameters, and then the actual temperature of the heated body is calibrated through the extended Kalman filter algorithm. Then, the calibrated actual temperature is used as the input of fuzzy PID control, and the working state of the heating device is controlled according to the relationship between the actual temperature of the heated body and the preset temperature, thereby controlling the temperature of the heated body, which can ensure the accuracy of the temperature control of the heated body under non-contact measurement.
