[0072] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0073] Usually, such as Figure 1As shown, a schematic diagram of the heating control results of the atomizer device is provided. In order to meet the user's inhalation needs during the heating control process, the atomizer device can adopt a rapid heating method in the P0 process, so that the working medium temperature rises rapidly to the temperature set in the P1 process, and maintains a relatively stable temperature after the P1 process.

[0074] However, when the above method is used to control the heating of the atomizing device, the heating control accuracy of the atomizing device will be low. This is because the working medium in the atomizing device has the characteristic of slow heat conduction. After the heating element set in the working medium of the atomizing device is heated at high power, the energy after high-power heating is enriched in the heating element but not conducted to the working medium. As a result, after the heating element stops heating, the energy enriched by the heating element causes the working medium temperature to still exceed the set P1 process temperature, or, because the heating element stops heating in advance, the energy of the heating element cannot reach the set P1 process temperature, affecting the user's inhalation effect.

[0075] In view of the above situation, in order to realize the heating control process of the atomization device, a heating control method based on pulse width modulation (PWM) can be adopted. The heating control method based on PWM is a control method with fixed frequency but variable duty cycle, such as Figure 2 As shown, the heating cycle of the heating element includes: the 1st cycle, the 2nd cycle, the 3rd cycle, and up to the Nth cycle. During the entire heating control process, the duration of each heating cycle of the heating element is the same, that is, the total time of the switch on time Ton and the switch off time Toff of the heating element remains unchanged. By adjusting Ton, different duty cycles can be achieved in different heating cycles, thereby achieving the effect of controlling the output; wherein, the fixed frequency f is the ratio of 1 to the first parameter, the first parameter is the sum of Ton and Toff, the duty cycle D is the ratio of Ton to the second parameter, and the second parameter is the sum of Ton and Toff.

[0076] To achieve precise control of the working medium, the PWM-based control method has high requirements for the heat transfer rate of the working medium, the sensor temperature measurement speed, and the sensor temperature measurement accuracy. It also requires high precision for the selected temperature sensor. Moreover, since some temperature sensors also need to be calibrated using other equipment before production, this will increase equipment investment, production processes and production time, and increase the total cost.

[0077] Moreover, although the PWM-based heating control method can achieve the effect of controlling the output by adjusting Ton, in actual application scenarios, setting the heating cycles of the heating elements to the same heating cycle will also lead to low heating control accuracy of the atomizing equipment.

[0078] In view of this, the present application provides a method for controlling heating of an atomizing device, which can be applied in the following situations: Figure 3 In the application environment shown, the application scenario includes a microcontroller unit (MCU) and a heating element arranged in a working medium. The microcontroller unit can be called a control chip. The control chip obtains the real-time detection temperature of the heating element of the atomization device in each detection cycle during the heating control process, and then determines the heating state of the heating element based on the heating time of the current heating cycle and the real-time detection temperature.

[0079] In one embodiment, Figure 4 As shown, a method for controlling heating of an atomizing device is provided, which is applied to Figure 1 Taking the MCU in the example, the following steps can be included:

[0080] S402, obtaining the real-time detection temperature of the heating element of the atomization device in each detection cycle during the heating control process.

[0081] In this embodiment, the atomization device includes a heating element arranged in a working medium. The working medium can be called a heated substance or an aerosol generating matrix. The form of the aerosol generating matrix can be liquid, gel, paste or solid, etc., which can be set according to the actual application scenario; for example, when the aerosol generating matrix is ​​solid, it can be a solid in the form of crushed, granular, powdered, strip or sheet.

[0082] Furthermore, by obtaining the real-time detection temperature of the heating element of the atomizing device in each detection cycle during the heating control process, the temperature of the heating element during the heating control process can be judged in real time. The energy generated by the temperature of the heating element affects the temperature of the working medium. Therefore, by judging the temperature of the heating element in real time, the temperature of the working medium can be judged in real time. Furthermore, based on the temperature of the working medium, the atomization process of the atomizing device can be judged to improve the user's inhalation effect.

[0083] The detection period may be 1 ms or other values. The specific value of the detection period may be set according to the actual application scenario and is not specifically limited in this embodiment.

[0084] S404: Determine the heating state of the heating element based on the heating duration of the current heating cycle and the real-time detected temperature.

[0085] In this embodiment, the real-time detection temperature of each detection cycle of the heating element can be obtained in real time based on the detection cycle. In this way, when the heating state of the heating element is determined based on the heating duration of the current heating cycle and the real-time detection temperature, the heating control of the atomization device can be accurately achieved, thereby improving the user's inhalation effect.

[0086] It should be noted that the heating time of the first heating cycle of the heating control process of the atomization device is the preset heating time. In this first heating cycle, the heating element can be heated according to the preset heating time and then enter the next heating cycle; or, in this first heating cycle, the heating element can be heated according to the preset heating time, and then the heating can be stopped according to the preset stop time before entering the next heating cycle. This embodiment does not limit this.

[0087] In summary, Figure 4 In the embodiment shown, by setting the detection cycle, the real-time detection temperature of the heating element of the atomization device in each detection cycle during the heating control process can be obtained. By taking into account the influence of the heating time of the current heating cycle on the heating state of the heating element, the heating state of the heating element can be determined based on the heating time of the current heating cycle and the real-time detection temperature. The accuracy of the judgment of the heating state of the heating element can be improved. When the accuracy of the judgment of the heating state of the heating element is high, the heating control accuracy of the atomization device is improved, and the user's inhalation effect is improved.

[0088] In one embodiment, the heating state of the heating element is determined based on the heating duration of the current heating cycle and the real-time detected temperature, including: if the real-time detected temperature reaches the target temperature, and the detection cycle corresponding to the real-time detected temperature is within the range of the heating duration of the current heating cycle, the heating process of the current heating cycle is controlled to end.

[0089] The target temperature may be set to 200° C. or other values. The specific value of the target temperature may be set according to the actual application scenario and is not limited in this embodiment.

[0090] It should be noted that the real-time detection temperature of the heating element is allowed to reach the upper limit of the target temperature, but is not allowed to exceed the upper limit of the target temperature. For example, the target temperature is 200°C and the upper limit of the target temperature is 230°C. By setting the upper limit of the target temperature of the heating element, damage to the heating element can be avoided to a certain extent.

[0091] In one embodiment, Figure 5 As shown, a flow chart of determining the heating state of the heating element based on the heating time of the current heating cycle and the real-time detection temperature is provided. Figure 1 The following steps are used as an example to illustrate the MCU in the example:

[0092] S502: If the real-time detected temperature within the heating time does not reach the target temperature, heating is stopped after the heating time of the current heating cycle ends.

[0093] In this embodiment, the detection cycle is shorter than the current heating time. Therefore, the real-time detection temperature of the heating element in each detection cycle within the heating time can be detected through the detection cycle. If the real-time detection temperature detected in each detection cycle does not reach the target temperature within the heating time of the current heating cycle, the heating can be stopped after the heating time of the current heating cycle ends, so that the temperature of the heating element can reach the target temperature after stopping the heating.

[0094] S504, obtaining the real-time temperature of the heating element after heating is stopped.

[0095] In this embodiment, the real-time temperature of the heating element is the real-time detection temperature of the detection period after the heating is stopped, wherein the real-time temperature of the heating element can be the real-time temperature detected in the last detection period within the heating time range, and the real-time temperature of the heating element can also be the real-time temperature detected at the end of the heating time. This embodiment does not limit this.

[0096] S506: Determine the heating time of the next heating cycle of the heating element based on the real-time temperature of the heating element.

[0097] In this embodiment, if the real-time temperature of the heating element is lower than the target temperature, the heating duration of the next heating cycle of the heating element can be calculated based on the real-time temperature of the heating element. Specifically, the heating duration of the next heating cycle of the heating element is calculated based on the real-time temperature of the heating element, including:

[0098] S5062: Determine the heating energy required to heat the heating element from the real-time temperature of the heating element to the target temperature.

[0099] S5064: Based on the heating energy, determine the heating time of the next heating cycle of the heating element.

[0100] Among them, in S5062, specifically, the heating energy can be obtained based on the difference between the target temperature and the real-time temperature of the heating element, the specific heat capacity of the material of the heating element and the mass of the heating element. For example, the heating energy is expressed as Q, the target temperature is expressed as T1, the real-time temperature of the heating element is expressed as T0, the specific heat capacity of the material of the heating element is expressed as C, and the mass of the heating element is expressed as m, then Q satisfies the following formula: Q = C × m × (T1-T0), wherein the unit of the specific heat capacity of the material of the heating element is J / (KG.℃).

[0101] As a specific example, if C×m is 1.5, the target temperature is 125°C, and the real-time temperature of the heating element is 100°C, then Q=1.5×(125°C-100°C)=37.5J.

[0102] In summary, Figure 5In the embodiment shown, by obtaining the real-time detection temperature of the detection cycle after the current heating cycle stops heating, and comparing the relationship between the real-time detection temperature and the target temperature, the heating energy required to heat the heating element to the target temperature based on the real-time temperature can be determined, and then based on the heating energy, the heating time of the next heating cycle of the heating element can be determined, so that the heating control process of the atomization equipment can be accurately controlled without exceeding the target temperature.

[0103] In one embodiment, Figure 6 As shown, a flow chart of determining the heating time of the next heating cycle of the heating element based on the heating energy is provided, such as Figure 6 The method shown is a further limitation of S5064, which is applied to Figure 1 The following steps are used as an example to illustrate the MCU in the example:

[0104] S602, obtaining the voltage value and current value of the target detection period of the heating element.

[0105] In this embodiment, the target detection period is a detection period corresponding to the real-time temperature of the heating element. S604 can be executed by obtaining the voltage value and the current value of the heating element during the target detection period.

[0106] S604: Determine the power of the heating element based on the voltage value and the current value.

[0107] In this embodiment, the power of the heating element is the product of the voltage value and the current value. For example, the power of the heating element is represented by P, the voltage value is represented by U, and the current value is represented by I, then P satisfies the following formula: P=U×I.

[0108] S606: Determine the heating duration of the next heating cycle of the heating element based on the power and the heating energy.

[0109] Specifically, the heating time of the next heating cycle of the heating element is the ratio of the heating energy to the power. For example, the heating time is represented by Ton, the heating energy is represented by Q, and the power is represented by P, then Ton satisfies the following formula: Ton = Q / P, for example, P = 25.92W, Q = 37.5J, then Ton = 37.5J / 25.92W = 1.447s.

[0110] In summary, Figure 6In the illustrated embodiment, by obtaining the voltage and current values ​​of the target detection cycle of the heating element, the power of the heating element can be determined based on the voltage and current values, and then the heating duration of the next heating cycle of the heating element can be determined based on the power and heating energy. In this way, by determining the heating duration of the next heating cycle of the heating element, the heating element can reach the target temperature from the real-time temperature of the heating element during the next heating cycle. Then, by controlling the temperature of the heating element in real time to reach the target temperature, the atomization process of the working medium can be maintained, thereby improving the user's inhalation effect.

[0111] It is understandable that in Figure 6 In the figure, the MCU determines the power of the heating element based on the voltage value and current value of the heating element. The MCU can also determine the power of the heating element based on the voltage value and resistance value of the heating element. Specifically, the power of the heating element is represented by P, the voltage value of the heating element is represented by U, and the resistance value of the heating element is represented by R. Then P satisfies the following formula: P = (U×U) / R. For example, if U = 3.6V and R = 0.5Ω, then P = (3.6×3.6) / 0.5 = 25.92W.

[0112] exist Figures 4 to 6 Based on the content shown, it can be understood that based on the different real-time detection temperatures T0 detected by the heating element in each detection cycle, according to the formula Q=C×m×(T1-T0), the heating energy 1 required for the heating element to reach the target temperature T1 from the real-time detection temperature of the heating element is also different. According to the formula Ton=Q / P, the heating time Ton of the heating element in the next heating cycle is also different, that is, the heating state of the heating element in each heating cycle is different.

[0113] For example, the heating state curve of the heating element in an application example is as follows: Figure 7 As shown, the heating time of the heating element in each heating cycle is represented by a high level, and the stopping time of the heating element in each heating cycle is represented by a low level. Figure 7 It can be seen that the duration of each heating cycle Ts of the heating element is different, and the heating duration and the heating stop duration of the heating element in each heating cycle are also different.

[0114] For example, the heating state curve of the heating element in an application example is as follows: Figure 8 As shown, the heating time of the heating element in each heating cycle is represented by a high level, and the heating stop time of the heating element in each heating cycle is represented by a low level. It can be seen that in different heating cycles Ts, the heating time of the heating element is different, and the heating stop time of the heating element is also different.

[0115] For example, the heating control curve of the atomization device in an application example is as follows: Figure 9As shown, the heating time of the heating element in each heating cycle is represented by a high level, and the heating time of the heating element in each heating cycle is represented by a low level. The heating time of the heating element in each heating cycle includes the heating time and the heating stop time.

[0116] In the heating state curve of the heating element, the heating time of the heating element in the P0 process is longer than the heating stop time, and the heating time of the heating element in the P1 process is less than the heating stop time. Correspondingly, in the temperature change curve of the working medium, the working medium is in a rapid heating process in the P0 process, and the temperature of the working medium remains stable in the P1 process. Based on the control of the heating state of the heating element, the temperature of the working medium can be controlled, thereby improving the heating control accuracy of the atomization equipment.

[0117] exist Figures 3 to 9 The contents shown are based on examples, such as Figure 10 As shown, a flow chart of a method for controlling heating of an atomizing device is provided, which may include the following steps:

[0118] S1002, obtaining the real-time detection temperature of the heating element of the atomization device in each detection cycle during the heating control process.

[0119] S1004: If the real-time detected temperature within the heating time does not reach the target temperature, heating is stopped after the heating time of the current heating cycle ends.

[0120] S1006, obtaining the real-time temperature of the heating element after stopping heating, where the real-time temperature of the heating element is the real-time detection temperature of the detection period after stopping heating.

[0121] S1008: If the real-time temperature of the heating element is lower than the target temperature, the heating energy is calculated based on the difference between the target temperature and the real-time temperature of the heating element, the material specific heat capacity of the heating element, and the mass of the heating element.

[0122] S1010, obtaining a voltage value and a current value of a target detection period of the heating element, where the target detection period is a detection period corresponding to the real-time temperature of the heating element.

[0123] S1012, determining the power of the heating element based on the voltage value and the current value.

[0124] S1014: Determine the heating duration of the next heating cycle of the heating element based on the power and heating energy.

[0125] In this embodiment, the specific contents of S1002-S1014 can be adapted to the description with reference to the above contents and will not be repeated here.

[0126] It should be noted that after obtaining the real-time detection temperature of the heating element of the atomization device in each detection cycle during the heating control process, if the real-time detection temperature reaches the target temperature and the detection cycle corresponding to the real-time detection temperature is within the range of the heating time of the current heating cycle, the heating process of the current heating cycle is controlled to end, thereby preventing the heating element temperature from exceeding the target temperature.

[0127] Among them, if the real-time detection temperature reaches the target temperature, and the detection period corresponding to the real-time detection temperature is within the range of the heating time of the current heating period, it means that the output energy Q corresponding to the real-time detection temperature of the heating element is excessive. Therefore, by controlling the heating switch to end the heating process of the current heating period, the working medium temperature will not exceed the set target temperature of the working medium based on the output energy, thereby accurately realizing the heating control of the atomization equipment and improving the user's inhalation effect.

[0128] It should be understood that, although the various steps in the flowcharts involved in the various embodiments described above are displayed in sequence according to the instructions of the arrows, these steps are not necessarily executed in sequence in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and these steps can be executed in other orders. Moreover, at least a portion of the steps in the flowcharts involved in the various embodiments described above can include multiple steps or multiple stages, and these steps or stages are not necessarily executed and completed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a portion of steps or stages in other steps.

[0129] In one embodiment of the present application, a heating control circuit for an atomizing device is also provided. Figure 11 As shown, one end of the power supply is grounded, the other end of the power supply is connected to the heating switch, the heating switch is also connected to one end of the heating element, the other end of the heating element is grounded, the other end of the power supply is also connected to the MCU, and a voltage / current sampling circuit is also provided between the MCU and the heating switch.

[0130] Among them, the power supply can provide a power supply voltage VCC for the heating switch, so that the heating switch can execute the on-off state indicated by the MCU based on the power supply voltage VCC; the power supply can provide an operating voltage VDD for the MCU, so that the MCU can be used to execute the steps in the atomization device heating control method based on the operating voltage VDD.

[0131] Specifically, the temperature sensor is used to obtain the real-time detection temperature of the heating element in each detection cycle during the heating control process; the control chip is used to determine the heating state of the heating element based on the heating duration of the current heating cycle and the real-time detection temperature, and based on the heating state of the heating element, control the on and off state of the heating switch to control the heating state of the heating element.

[0132] In one embodiment, the control chip is also used to control the state of the heating switch to be on if the real-time detected temperature reaches the target temperature and the detection period corresponding to the real-time detected temperature is within the range of the heating duration of the current heating cycle, so as to control the heating process of the current heating cycle to end.

[0133] In one embodiment, the control chip is also used to control the state of the heating switch to the open state after the heating time of the current heating cycle ends if the real-time detected temperature within the heating time does not reach the target temperature, so as to control the heating element to stop heating; the temperature sensor is also used to obtain the real-time temperature of the heating element after the heating is stopped, and the real-time temperature of the heating element is the real-time detected temperature of the detection cycle after the heating is stopped; the control chip is also used to determine the heating time of the next heating cycle of the heating element based on the real-time temperature of the heating element.

[0134] In one embodiment, the control chip is further configured to calculate the heating time of the next heating cycle of the heating element according to the real-time temperature of the heating element if the real-time temperature of the heating element is lower than the target temperature.

[0135] In one embodiment, the control chip is further used to determine the heating energy required to heat the heating element from the real-time temperature of the heating element to the target temperature; and based on the heating energy, determine the heating time of the next heating cycle of the heating element.

[0136] In one embodiment, the control chip is further used to calculate the heating energy based on the difference between the target temperature and the real-time temperature of the heating element, the material specific heat capacity of the heating element, and the mass of the heating element.

[0137] In one embodiment, the voltage / current sampling circuit is used to obtain the voltage value and current value of the target detection cycle of the heating element; the target detection cycle is the detection cycle corresponding to the real-time temperature of the heating element; the control chip is also used to determine the power of the heating element based on the voltage value and the current value; based on the power and heating energy, determine the heating time of the next heating cycle of the heating element.

[0138] In one embodiment, the control chip is further used to set the heating time of the next heating cycle, which is the ratio of heating energy to power.

[0139] In one embodiment, the control chip is further configured to set the heating duration of the first heating cycle of the heating control process to a preset heating duration.

[0140] In combination with the above content, it can be understood that if the temperature difference between the heating element and the real-time temperature of the heating element is heated to the target temperature, the greater the temperature difference, the more heating energy the heating element needs to release, the longer the switch-on time Ton of the heating switch controlled by the MCU, and the higher the switch conduction rate; if the temperature difference between the heating element and the real-time temperature of the heating element is heated to the target temperature, the less heating energy the heating element needs to release, the longer the switch-off time Toff of the heating switch controlled by the MCU, and the lower the switch conduction rate, thereby achieving the purpose of balanced temperature control.

[0141] In combination with the above content, it should be noted that the heating control method for atomizing equipment proposed in this application is a heating control method based on pulse frequency modulation (PFM). Compared with the heating control method based on PWM, the heating control method based on PFM does not require precise temperature control of the heating element. This is because, in some application scenarios, the heating element has a certain adaptive temperature difference, which is more conducive to the conduction of the output energy of the heating element and the increase of the heating rate; when there is no need to precisely control the temperature of the heating element, the processing process of the MCU will also be relatively reduced, thereby reducing the workload of the MCU and improving the operation processing efficiency.

[0142] Moreover, the PFM-based heating control method does not require a high-precision temperature sensor. Even if the obtained heating element temperature is inaccurate, the heating element's heating rate can be controlled by continuously measuring the heating element's temperature during the detection period. At most, the heating period of the heating element can be increased. Compared with the PWM-based heating control method that requires a high-precision temperature sensor, the PFM-based heating control method can eliminate the need for calibration equipment and tedious calibration work, thereby reducing costs.

[0143] In the above description, the heating control method of the atomizing device is implemented based on the temperature of the heating element. Since the temperature of the heating element will also affect the temperature of the working medium, the heating control of the atomizing device can also be achieved through the temperature of the working medium. For example, the maximum temperature of the working medium in the heating cycle and the last working medium temperature before the end of the heating cycle are obtained. Based on the maximum temperature of the working medium in the heating cycle and the last working medium temperature in the heating cycle, the temperature rise and fall trend can be judged, and then the temperature rise and fall trend can be used to judge whether Ton and Toff need to be adjusted in the next heating cycle; or, based on the difference between the last working medium temperature in the heating cycle and the target temperature of the working medium, the amplitude of the temperature difference between the two can be judged. If the temperature difference is large, Ton and Toff can be adjusted synchronously. If the temperature difference is small, Ton or Toff can be adjusted.

[0144] In possible situations, for heating control with a large temperature difference, for example, the working medium needs to be quickly heated from room temperature (25°C) to the working medium target temperature (150°C), by referring to the method of calculating the power of the heating element, the heating energy of the working medium from room temperature to the working medium target temperature can be calculated. The heating energy is very large, so a long switch on time Ton can be set. For example, the switch on time Ton is greater than 5s. By fully opening the switch, the heating element can be heated according to the switch on time Ton. In this way, the energy output by the heating element can cause the working medium temperature to rise until the working medium temperature reaches the working medium target temperature.

[0147] In one embodiment, the state determination module is also used to control the end of the heating process of the current heating cycle if the real-time detection temperature reaches the target temperature and the detection period corresponding to the real-time detection temperature is within the range of the heating time of the current heating cycle.
