And the second temperature control mode is switched back to the first temperature control mode to carry out temperature control on the heating body, and circulation is carried out in this way. On the basis, the dynamic response speed to the temperature change of the heating body is increased, and the overshoot phenomenon when the temperature of the heating body rises / drops is avoided.

Description

[Technical field]

[0001] The present application relates to the technical field of electronic atomization, and in particular to a multi-mode parallel temperature control method and related equipment and storage media. [Background technology]

[0002] In the related technology, for HNB (Heat Not Burning) type electronic atomization products, the core components include MCU (Micro Control Unit), power supply, aerosol generator and peripheral heating element mounted on the aerosol generator. MCU can use the power supply to transmit electrical energy to the peripheral heating element, so that the peripheral heating element heats up, and then heats the aerosol generator to produce aerosol. In this process, MCU can also detect the temperature of the peripheral heating element in real time, and adjust the electrical energy transmitted to the peripheral heating element by the power supply to achieve temperature control of the peripheral heating element. However, when the temperature of the peripheral heating element changes greatly and the temperature difference changes little, the existing temperature control scheme has a very slow dynamic response speed to the temperature change, which is often not timely enough, resulting in the phenomenon of temperature rise / fall overshoot, which seriously reduces the uniformity of heating of the aerosol generator.

[0003] Therefore, it is necessary to improve the existing temperature control solutions for electronic atomization products. [Summary of the invention]

[0004] The present application provides a multi-mode parallel temperature control method and related equipment and storage medium, aiming to solve the problem of slow dynamic response speed of electronic atomization products to temperature changes of heating elements in related technologies.

[0005] In order to solve the above-mentioned technical problems existing in the related art, the first aspect of the embodiment of the present application provides a multi-mode parallel temperature control method, which is applied to an electronic atomization device equipped with a heating element, and the temperature control method includes: transmitting electric energy to the heating element to heat the heating element; when the heating time of the heating element is less than or equal to the preset time, the heating element is temperature controlled based on a first temperature control method, and the goal of the first temperature control method is to make the actual temperature of the heating element consistent with the corresponding preset temperature on the preset temperature curve; when the heating time is greater than the preset time, in the process of temperature controlling the heating element based on the first temperature control method, the actual temperature change rate of the heating element is calculated; when the actual temperature change rate is consistent with the corresponding slope of the preset temperature curve, the temperature control of the heating element is kept unchanged based on the first temperature control method; when the actual temperature change rate does not meet the corresponding slope of the preset temperature curve, the first temperature control method is switched to the second temperature control method to temperature control the heating element, and the goal of the second temperature control method is to make the actual temperature change rate consistent with the corresponding slope of the preset temperature curve; when the goal of the second temperature control method is achieved, the second temperature control method is switched back to the first temperature control method to temperature control the heating element.

[0006] The second aspect of the embodiment of the present application provides an electronic atomization device, including an aerosol generator, a heating element, a heating unit, a timing unit, a temperature control unit, a power supply and a temperature detection unit. The heating element is sleeved on the aerosol generator, and the inner wall of the heating element is in contact with the aerosol generator; wherein: the heating unit is used to transmit the electric energy provided by the power supply to the heating element to heat the heating element, and the heat emitted by the heating element is used to heat the aerosol generator to generate an aerosol; the timing unit is used to record the heating time of the heating element; the temperature detection unit is used to detect the actual temperature of the heating element; the temperature control unit is used to obtain the heating time and the actual temperature, and perform temperature control on the heating element based on the temperature control method mentioned in the first aspect of the embodiment of the present application.

[0007] A third aspect of an embodiment of the present application provides a temperature control unit, which includes a memory and a processor, wherein the memory stores at least one segment of computer instructions, the processor is communicatively connected to the memory, and the processor is used to call at least one segment of computer instructions stored in the memory to implement the temperature control method mentioned in the first aspect of the embodiment of the present application.

[0008] A fourth aspect of an embodiment of the present application provides a computer-readable storage medium, on which at least one segment of computer instructions is stored, and the at least one segment of computer instructions is used to be called by a processor to implement the temperature control method mentioned in the first aspect of the embodiment of the present application.

[0009] Through the implementation of the above-mentioned technical scheme of the present application, in the initial stage of heating the heating element (i.e., the heating time is less than or equal to the preset time), the heating element can be temperature controlled based on the first temperature control method, so that the actual temperature of the heating element is consistent with the corresponding preset temperature on the preset temperature curve; in the later stage of heating the heating element (i.e., the heating time is greater than the preset time), the heating element is still temperature controlled based on the first temperature control method, but it is necessary to calculate the actual temperature change rate of the heating element in real time, and judge whether the actual temperature change rate is consistent with the corresponding slope of the preset temperature curve. If the actual temperature change rate is consistent with the corresponding slope of the preset temperature curve, then the temperature control of the heating element is kept unchanged based on the first temperature control method. Once the actual temperature change rate does not meet the corresponding slope of the preset temperature curve, it is necessary to switch the current first temperature control method to the second temperature control method, and temperature control the heating element based on the second temperature control method, so that the actual temperature change rate is consistent with the corresponding slope of the preset temperature curve, and then switch the second temperature control method back to the first temperature control method to temperature control the heating element, and so on. It can be seen that the present application sets two temperature control modes for the heating element. These two temperature control modes can be switched in real time according to specified conditions during the heating process of the heating element, thereby improving the dynamic response speed to the temperature change of the heating element, and making the actual temperature of the heating element and its change rate always consistent with the preset temperature curve, which not only avoids the overshoot phenomenon when the temperature of the heating element rises / falls, but also ensures the uniformity of the heating temperature field of the aerosol generator in the electronic atomization device.

[0015] In order to make the purpose, technical solutions and advantages of the present application more obvious and easy to understand, the present application will be clearly and completely described below in conjunction with the embodiments of the present application and the corresponding drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. It should be understood that the various embodiments of the present application described below are only used to explain the present application and are not used to limit the present application, that is, based on the various embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present application. In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0016] In the related art, for heat-not-burn electronic atomization products, when the temperature of its inner circumferential heating element changes greatly and the temperature difference changes slightly, its dynamic response speed to the temperature change is very slow and often not timely enough, resulting in temperature rise / fall overshoot (i.e., the temperature excessively exceeds / is lower than the predetermined temperature). This seriously reduces the uniformity of heating of the aerosol generator and also affects the safety of electronic atomization products. To this end, the present application proposes a multi-mode parallel temperature control method and an electronic atomization device using the temperature control method in the embodiments below. It should be noted that the temperature control method is actually one or more computer instructions. The present application can effectively solve the above-mentioned technical problems existing in the related art by executing the one or more computer instructions in the above-mentioned electronic atomization device.

[0017] Figure 1 The schematic diagram of the structure of the electronic atomization device is shown. In some embodiments, the electronic atomization device includes an aerosol generator 110, a heating element 120, a single chip microcomputer 130 and a power supply 140. The single chip microcomputer 130 includes a heating unit 131, a timing unit 134, a temperature control unit 132 and a temperature detection unit 133. The heating element 120 is sleeved on the aerosol generator 110, and the inner wall of the heating element 120 is in contact with the outer surface of the aerosol generator 110. The power supply 140 is electrically connected to the heating unit 131, the heating unit 131 and the temperature detection unit 133 are electrically connected to the heating element 120, the temperature detection unit 133 is electrically connected to the temperature control unit 132, the temperature control unit 132 is electrically connected to the heating unit 131, and the heating unit 131 and the temperature control unit 132 are electrically connected to the timing unit 134.

[0018] Specifically, the heating unit 131 can transmit the electric energy provided by the power supply 140 to the heating element 120, thereby heating the heating element 120, and the heat emitted by the heating element 120 can heat the aerosol generator 110 to generate an aerosol for the user to inhale. When the heating unit 131 starts to transmit the electric energy provided by the power supply 140 to the heating element 120, it will simultaneously send a heating signal to the timing unit 134, informing the timing unit 134 that the heating element 120 has started to be heated at the current moment, and the timing unit 134 starts timing after receiving this heating signal, the purpose of which is to record the heating time of the heating element 120. In the embodiment of the present application, the heating time refers to the time elapsed after the heating element 120 starts to be heated, and its starting time is the time when the electric energy starts to be transmitted to the heating element 120, and the end time is the current time.

[0019] Furthermore, the temperature detection unit 133 can detect the circumferential temperature of the heating element 120 (referred to herein as the actual temperature) in real time during the entire heating process, and transmit the detected actual temperature to the temperature control unit 132. In addition to receiving the actual temperature from the temperature detection unit 133, the temperature control unit 132 also needs to obtain the heating time from the timing unit 134, and calculate the corresponding actual temperature change rate based on the actual temperature obtained, and finally perform temperature control on the heating element 120 based on the temperature control method to be provided below in this application, so that the actual temperature and the actual temperature change rate of the heating element 120 are consistent with expectations.

[0020] It can be understood that the control targets for temperature control of the heating element 120 include two, namely the actual temperature of the heating element 120 and the actual temperature change rate. The reason why the heating element 120 has the actual temperature and the actual temperature change rate is that it is being heated by the heating unit 131. At the same time, since the energy used by the heating unit 131 to heat the heating element 120 comes from the electric energy supplied by the power supply 140, if the actual temperature and the actual temperature change rate of the heating element 120 are to be regulated, it is necessary to achieve this by regulating the electric energy delivered to the heating element 120 by the heating unit 131. Specifically, the electrical parameters of the delivered electric energy can be regulated. That is to say, the temperature control function of the temperature control unit 132 means that it can control the heating unit 131, thereby changing the electric energy delivered to the heating element 120 by the heating unit 131, and then changing the actual temperature and the actual temperature change rate of the heating element 120.

[0021] Preferably, a temperature curve for the heating element 120 (referred to as a preset temperature curve) can be pre-designed, such as Figure 2As shown, the preset temperature curve is actually a preset time-temperature curve (the horizontal axis is time, the vertical axis is temperature), and the preset temperature curve expresses the expected change relationship of the temperature of the heating element 120 with time during the entire heating process (or heating cycle) of the heating element 120. During the actual heating process of the heating element 120, there will be an actual temperature curve, which is essentially the same as the preset temperature curve, except that the preset temperature curve is expected, while the actual temperature curve is when the heating element 120 is actually heated. On this basis, when the actual temperature curve of the heating element 120 is consistent with the preset temperature curve, or in other words, when the actual temperature / actual temperature change rate of the heating element 120 is consistent with the preset temperature curve, it is considered that the actual temperature / actual temperature change rate of the heating element 120 is consistent with expectations, otherwise it is considered that the actual temperature / actual temperature change rate of the heating element 120 is inconsistent with expectations.

[0022] It should be noted that the preset temperature curve defines the expected temperature of the heating element 120 at each moment after the heating of the heating element 120 begins, and during the actual heating process of the heating element 120, its actual temperature at each moment should be the same as / similar to the corresponding expected temperature on the preset temperature curve. It should also be noted that, since the slope of the time-temperature curve expresses the temperature change rate, the slope of the preset temperature curve is used to define the expected temperature change rate of the heating element 120, and during the actual heating process of the heating element 120, its actual temperature change rate at each moment should be the same as / similar to the corresponding slope (i.e., the expected temperature change rate) in the preset temperature curve.

[0023] Preferably, the shape of the heating element 120 is cylindrical, and of course, it can also adopt other shapes commonly used in the art, such as a rectangular parallelepiped, a flat shape, etc. In addition, as mentioned above, the temperature detection unit 133 can detect the actual temperature of the heating element 120 in real time during the entire heating process, and the detection form of the actual temperature can adopt any form commonly used in the art, such as setting a contact temperature sensor on the outer wall of the heating element 120, and electrically connecting the contact temperature sensor to the temperature detection unit 133, and in the actual heating process of the heating element 120, the temperature detection unit 133 can obtain the measurement data of the contact temperature sensor in real time, and obtain the actual temperature of the heating element 120 based on the obtained measurement data; for example, since the resistance of the heating element 120 will change with the change of its own temperature, the temperature detection unit 133 can be configured with a resistance detection function, that is, the temperature detection unit 133 can detect the resistance of the heating element 120 in real time, and then the actual temperature of the heating element 120 can be obtained based on the preset corresponding relationship between the resistance and temperature of the heating element 120.

[0024] As one example, Figure 3A schematic diagram of heating and temperature control of the heating element 120 is shown. The temperature control unit 132 includes a memory 1321 and a processor 1322. The heating unit 131, the timing unit 134 and the temperature detection unit 133 are electrically connected to the processor 1322 respectively. The processor 1322 is communicatively connected to the memory 1321. The memory 1321 stores at least one section of computer instructions, which is actually the temperature control method of the present application. That is, the processor 1322 can obtain the actual temperature of the heating element 120 from the temperature detection unit 133 and the heating time of the heating element 120 from the timing unit 134, and calculate the corresponding actual temperature change rate according to the actual temperature obtained, and at the same time call at least one section of computer instructions stored in the memory 1321 to control the temperature of the heating element 120 through the temperature control method of the present application.

[0025] In some implementations of this embodiment, the processor 1322 is composed of an integrated circuit, which may be composed of a single packaged integrated circuit, or may be composed of multiple packaged integrated circuits with the same or different functions, including a central processing unit (CPU), a microprocessor, a neural network chip, a digital processing chip, a graphics processor, and any one or more combinations of various control chips. It is understandable that the processor 1322 is the control core of the temperature control unit 132, which uses various interfaces and lines to connect the various components of the entire temperature control unit 132, and realizes various functions and data processing of the temperature control unit 132 by running or executing computer instructions or modules and calling data, such as realizing the temperature control function of the heating element 120.

[0026] In some implementations of this embodiment, the memory 1321 includes at least one type of computer-readable storage medium, which may include but is not limited to flash memory, mobile hard disk, multimedia card, card-type memory (such as SD memory, DX memory, etc.), magnetic memory, disk and optical disk. In these implementations, the memory 1321 may be an internal storage unit of the temperature control unit 132 (such as a mobile hard disk of the temperature control unit 132), or an external storage device of the temperature control unit 132, such as a plug-in mobile hard disk, smart memory card (SMC), secure digital (SD) card and flash memory card equipped on the temperature control unit 132, or the memory 1321 is both an internal storage unit and an external storage device of the temperature control unit 132. Furthermore, the memory 1321 can not only be used to store application software, various data and computer instructions (such as codes for implementing temperature control functions of the heating element 120, etc.) installed in the temperature control unit 132, but can also be used to temporarily store data that has been output or is to be output; in actual applications, the processor 1322 can call and run the computer instructions stored in the memory 1321, so as to realize functions such as temperature control of the heating element 120.

[0027] As one of the embodiments, in addition to the structures listed above, the electronic atomization device may also include other commonly used structures in the electronic atomization products in the field, such as a power management unit 135 integrated in the single-chip microcomputer 130, which is electrically connected to the power supply 140 and is mainly used to implement the management function of the power supply 140, which may include but is not limited to temperature monitoring, power monitoring, low voltage protection, overcurrent protection and charging management; for example, an LED display light 150 arranged on the housing of the electronic atomization device and a display control unit 136 integrated in the single-chip microcomputer 130, which is electrically connected to the LED display light 150, which can control the LED display light 150 to emit constant light of different colors and / or flashing light of different colors, which is mainly used to indicate different working states of the electronic atomization device, which may include but is not limited to power-on state, preheating state, low power state, heating state, heating completion state and charging completion state; this embodiment will not list them one by one.

[0028] The above embodiments are only preferred implementations of the present application, and they are not the only limitations on the contents related to the electronic atomization device; in this regard, those skilled in the art can flexibly set them according to the actual application scenarios based on the above embodiments. Below, the multi-mode parallel temperature control method implemented by the processor 1322 in the temperature control unit 132 by executing one or more computer instructions will be described in detail.

[0029] Figure 4 1 is a flow chart of the multi-mode parallel temperature control method of the present application. In some embodiments, the multi-mode parallel temperature control method includes six steps from S401 to S406. In each of the following steps, the present application will describe the processor 1322 in the temperature control unit 132 as the execution subject.

[0030] S401 , transmitting electric energy to the heating element 120 to heat the heating element 120 .

[0031] In these embodiments, when using the electronic atomization device, it is necessary to first transmit electric energy to the heating element 120 to heat the heating element 120. Specifically, when the user presses the power button of the electronic atomization device, the heating unit 131 can transmit the electric energy provided by the power supply 140 to the heating element 120, thereby heating the heating element 120, and the heat emitted by the heating element 120 can heat the aerosol generator 110 to generate aerosol for the user to inhale.

[0032] S402, when the heating time of the heating element 120 is less than or equal to the preset time, the heating element 120 is temperature controlled based on a first temperature control method, wherein the first temperature control method aims to make the actual temperature of the heating element 120 consistent with the corresponding preset temperature on the preset temperature curve.

[0033] In these embodiments, when the heating unit 131 starts to transmit the electric energy provided by the power supply 140 to the heating element 120, it will simultaneously send a heating signal to the timing unit 134, informing the timing unit 134 that the heating element 120 has started to be heated at the current moment, and the timing unit 134 starts timing after receiving the heating signal, the purpose of which is to record the heating time of the heating element 120. The heating time refers to the time elapsed after the heating of the heating element 120 begins, and its starting time is the time when the electric energy starts to be transmitted to the heating element 120, and the ending time is the current time. At the same time, the temperature detection unit 133 can detect the actual temperature of the heating element 120 in real time, and transmit the detected actual temperature to the processor 1322 of the temperature control unit 132.

[0034] Based on this, in S402, the processor 1322 of the temperature control unit 132 can receive the actual temperature from the temperature detection unit 133, and can also obtain the heating time of the heating element 120 from the timing unit 134, and determine the size relationship between the obtained heating time and the preset time. When the obtained heating time is less than or equal to the preset time, the processor 1322 can adjust the electric energy delivered to the heating element 120 by the heating unit 131 based on the first temperature control method, thereby achieving the regulation of the actual temperature of the heating element 120, so that the actual temperature of the heating element 120 is consistent with the corresponding preset temperature on the preset temperature curve. It should be noted that the target of the first temperature control method is the actual temperature of the heating element 120. In the initial stage of heating the heating element 120, that is, when the heating time is less than or equal to the preset time, the heating element 120 usually only has an initial temperature, and there is actually no temperature change rate. Therefore, the heating element 120 can be directly temperature controlled based on the first temperature control method without using the second temperature control method below that uses the actual temperature change rate as the control target; preferably, the preset time is configured to be 2 seconds. It should also be noted that the actual temperature of the heating element 120 and the corresponding preset temperature on the preset temperature curve satisfy a corresponding relationship in time. Assuming that the current time is the 3rd second after the heating of the heating element 120 begins, the actual temperature of the heating element 120 at the current time should be consistent with the preset temperature corresponding to the 3rd second in the preset temperature curve.

[0035] As one of the embodiments, the processor 1322 of the temperature control unit 132 performs temperature control on the heating element 120 based on the first temperature control method, including: the processor 1322 obtains the actual temperature of the heating element 120 from the temperature detection unit 133, and determines whether the actual temperature meets the corresponding preset temperature on the preset temperature curve; if the actual temperature does not meet the corresponding preset temperature on the preset temperature curve, the electric energy supplied to the heating element 120 by the heating unit 131 is adjusted, and then the duty cycle of heating the heating element 120 is adjusted so that the actual temperature meets the corresponding preset temperature on the preset temperature curve. In this embodiment, the processor 1322 regulates the electric energy delivered by the heating unit 131 to the heating element 120 based on the first temperature control method. In fact, what is regulated is the duty cycle of heating the heating element 120. Since the heating form of the heating element 120 is energized, the duty cycle here refers to the proportion of the energization time of the heating element 120 relative to the unit time. In addition, it should be noted that in the process of heating the heating element 120, it is necessary to regulate the actual temperature of the heating element 120 and its rate of change, so the energization of the heating element 120 is not continuous, but intermittent.

[0036] In some implementations of this embodiment, the processor 1322 of the temperature control unit 132 determines whether the actual temperature meets the corresponding preset temperature on the preset temperature curve, including: the processor 1322 compares the actual temperature with the corresponding preset temperature on the preset temperature curve; and determines whether the actual temperature meets the corresponding preset temperature on the preset temperature curve according to the comparison result. As one implementation, the processor 1322 of the temperature control unit 132 determines whether the actual temperature of the heating element 120 meets the corresponding preset temperature on the preset temperature curve according to the comparison result, including: when the actual temperature is equal to the corresponding preset temperature on the preset temperature curve, determining that the actual temperature meets the corresponding preset temperature on the preset temperature curve; when the actual temperature is not equal to the corresponding preset temperature on the preset temperature curve, determining that the actual temperature does not meet the corresponding preset temperature on the preset temperature curve. As another implementation method, the processor 1322 of the temperature control unit 132 determines whether the actual temperature of the heating element 120 is consistent with the corresponding preset temperature on the preset temperature curve based on the comparison result, including: when the difference between the actual temperature and the corresponding preset temperature on the preset temperature curve is within the preset difference range, it means that the actual temperature and the corresponding preset temperature on the preset temperature curve are relatively close, and it can be determined that the actual temperature is consistent with the corresponding preset temperature on the preset temperature curve; when the difference between the actual temperature and the corresponding preset temperature on the preset temperature curve is outside the preset difference range, it means that the actual temperature and the corresponding preset temperature on the preset temperature curve are significantly different, and it can be determined that the actual temperature does not match the corresponding preset temperature on the preset temperature curve.

[0037] In some other implementations of this embodiment, the processor 1322 of the temperature control unit 132 determines whether the actual temperature meets the corresponding preset temperature on the preset temperature curve, including: the processor 1322 generates an actual temperature curve of the heating element 120 based on the actual temperature obtained from the temperature detection unit 133; matches the actual temperature curve with the preset temperature curve to obtain a first coincidence threshold between the actual temperature curve and the preset temperature curve; determines whether the first coincidence threshold is within a first preset range; if the first coincidence threshold is within the first preset range, it indicates that the actual temperature curve and the preset temperature curve are almost coincident, and it can be determined that the actual temperature of the heating element 120 meets the corresponding preset temperature on the preset temperature curve; if the first coincidence threshold is outside the first preset range, it indicates that the actual temperature curve and the preset temperature curve are quite different, and it can be determined that the actual temperature of the heating element 120 does not meet the corresponding preset temperature on the preset temperature curve.

[0038] S403 . When the heating time is longer than the preset time, in the process of temperature controlling the heating element 120 based on the first temperature control method, calculating the actual temperature change rate of the heating element 120 .

[0039] In these embodiments, if the processor 1322 of the temperature control unit 132 in S402 determines that the heating time of the heating element 120 is greater than the preset time, then in S403 the processor 1322 can still regulate the electric energy supplied to the heating element 120 by the heating unit 131 based on the first temperature control method, thereby achieving the regulation of the actual temperature of the heating element 120, so that the actual temperature of the heating element 120 is consistent with the corresponding preset temperature on the preset temperature curve. However, as mentioned above, in the initial stage of heating the heating element 120 (i.e., the heating time is less than or equal to the preset time), the heating element 120 only has an initial temperature, and it has no temperature change rate. Therefore, the first temperature control method with the actual temperature as the control target can be directly used to control the temperature of the heating element 120, without using the second temperature control method with the actual temperature change rate as the control target; and in the later stage of heating the heating element 120 (i.e., the heating time is greater than the preset time), the heating element 120 has an actual temperature change rate, and at this time it is necessary to consider Whether to use the second temperature control method to control the temperature of the heating element 120, that is, in S403, the processor 1322 not only needs to continue to control the temperature of the heating element 120 based on the first temperature control method so that its actual temperature matches the corresponding preset temperature on the preset temperature curve, but also needs to calculate the actual temperature change rate of the heating element 120 based on the actual temperature obtained from the temperature detection unit 133, so as to determine whether it is necessary to switch the current first temperature control method to the second temperature control method, that is, to determine whether it is necessary to adjust the actual temperature change rate of the heating element 120.

[0040] S404: When the actual temperature change rate matches the corresponding slope of the preset temperature curve, the temperature of the heating element 120 is kept unchanged based on the first temperature control method.

[0041] In these embodiments, after the processor 1322 of the temperature control unit 132 in S403 calculates the actual temperature change rate of the heating element 120 based on the actual temperature obtained from the temperature detection unit 133, the calculated actual temperature change rate can be compared with the corresponding slope of the preset temperature curve (i.e., the preset temperature change rate) to determine whether the actual temperature change rate is consistent with the corresponding slope of the preset temperature curve. If the judgment result is that the actual temperature change rate is consistent with the corresponding slope of the preset temperature curve, then it means that the actual temperature change rate of the heating element 120 is in line with expectations, that is, there is no need to adjust the actual temperature change rate of the heating element 120. At this time, the processor 1322 only needs to maintain the temperature control of the heating element 120 based on the first temperature control method.

[0042] S405. When the actual temperature change rate does not conform to the corresponding slope of the preset temperature curve, the first temperature control mode is switched to the second temperature control mode to control the temperature of the heating element 120. The goal of the second temperature control mode is to make the actual temperature change rate conform to the corresponding slope of the preset temperature curve.

[0043] In these embodiments, if the processor 1322 of the temperature control unit 132 determines in S404 that the actual temperature change rate of the heating element 120 does not match the corresponding slope of the preset temperature curve, then it means that the actual temperature change rate of the heating element 120 is not in line with expectations, and at this time, it is necessary to regulate the actual temperature change rate of the heating element 120. Specifically, the processor 1322 of the temperature control unit 132 can switch the current first temperature control mode to the second temperature control mode, and regulate the electric energy delivered to the heating element 120 by the heating unit 131 based on the second temperature control mode, thereby realizing the regulation of the actual temperature change rate of the heating element 120, so that the actual temperature change rate of the heating element 120 is consistent with the corresponding slope on the preset temperature curve.

[0044] As one embodiment, the processor 1322 of the temperature control unit 132 performs temperature control on the heating element 120 based on the second temperature control method, including: adjusting the electric energy delivered to the heating element 120 by the heating unit 131, and then adjusting the duty cycle of heating the heating element 120, so that the actual temperature change rate is consistent with the corresponding slope on the preset temperature curve. In this embodiment, the processor 1322 regulates the electric energy delivered to the heating element 120 by the heating unit 131 based on the second temperature control method, and actually regulates the duty cycle of heating the heating element 120. Since the heating form of the heating element 120 is electrification, the duty cycle here refers to the proportion of the electrification time of the heating element 120 relative to the unit time. In addition, it should be noted that the actual temperature change rate of the heating element 120 and the corresponding slope of the preset temperature curve satisfy the corresponding relationship in time. Assuming that the current time is the 5th second after the heating element 120 starts to be heated, the actual temperature change rate of the heating element 120 at the current time should be consistent with the slope corresponding to the 5th second in the preset temperature curve (i.e., the preset temperature change rate). Figure 2 ,like Figure 2 As shown at A in FIG. 1 , the slope of the actual temperature curve (actual temperature change rate) is larger than that of the preset temperature curve, so the actual temperature change rate needs to be regulated by the second temperature control method; Figure 2 As shown at B in FIG. 1 , the slope of the actual temperature curve (actual temperature change rate) is smaller than that of the preset temperature curve, so the actual temperature change rate needs to be regulated by the second temperature control method.

[0045] As one embodiment, the step in which the processor 1322 of the temperature control unit 132 in S405 determines whether the actual temperature change rate is consistent with the corresponding slope of the preset temperature curve, includes: the processor 1322 compares the calculated actual temperature change rate with the corresponding slope of the preset temperature curve; and determines whether the actual temperature change rate is consistent with the corresponding slope of the preset temperature curve based on the comparison result.

[0046] In some implementations of this embodiment, the processor 1322 of the temperature control unit 132 determines whether the actual temperature change rate meets the corresponding slope of the preset temperature curve based on the comparison result, including: when the actual temperature change rate of the heating element 120 is equal to the corresponding slope of the preset temperature curve, it can be determined that the actual temperature change rate of the heating element 120 meets the corresponding slope of the preset temperature curve; when the actual temperature change rate of the heating element 120 is not equal to the corresponding slope of the preset temperature curve, it can be determined that the actual temperature change rate of the heating element 120 does not meet the corresponding slope of the preset temperature curve. In some other implementations of this embodiment, the processor 1322 of the temperature control unit 132 determines whether the actual temperature change rate meets the corresponding slope of the preset temperature curve based on the comparison result, including: when the difference between the actual temperature change rate of the heating element 120 and the corresponding slope of the preset temperature curve is within the preset difference range, it means that the actual temperature change rate and the corresponding slope of the preset temperature curve are relatively close, and it can be determined that the actual temperature change rate of the heating element 120 meets the corresponding slope of the preset temperature curve; when the difference between the actual temperature change rate of the heating element 120 and the corresponding slope of the preset temperature curve is outside the preset difference range, it means that the actual temperature change rate and the corresponding slope of the preset temperature curve are significantly different, and it can be determined that the actual temperature change rate of the heating element 120 does not meet the corresponding slope of the preset temperature curve. In some other implementations of the present embodiment, the processor 1322 of the temperature control unit 132 determines whether the actual temperature change rate meets the corresponding slope of the preset temperature curve based on the comparison result, including: when the actual temperature change rate is 90% to 110% of the corresponding slope of the preset temperature curve, it means that the actual temperature change rate is relatively close to the corresponding slope of the preset temperature curve, and it can be determined that the actual temperature change rate meets the corresponding slope of the preset temperature curve; when the actual temperature change rate is less than 90% or more than 110% of the corresponding slope of the preset temperature curve, it means that the actual temperature change rate is significantly different from the corresponding slope of the preset temperature curve, and it can be determined that the actual temperature change rate does not meet the corresponding slope of the preset temperature curve.

[0047] As another embodiment, the step of the processor 1322 of the temperature control unit 132 in S405 determining whether the actual temperature change rate is consistent with the corresponding slope of the preset temperature curve includes: the processor 1322 generates an actual temperature curve of the heating element 120 according to the actual temperature obtained from the temperature detection unit 133, and generates an actual slope tangent indicating the actual temperature change rate on the actual temperature curve; generates a corresponding preset slope tangent on the preset temperature curve; matches the actual slope tangent with the preset slope tangent to obtain a second coincidence threshold between the actual slope tangent and the preset slope tangent; determines whether the second coincidence threshold is within a second preset range; if the second coincidence threshold is within the second preset range, it indicates that the actual slope tangent and the preset slope tangent are almost coincident, and it can be determined that the actual temperature change rate of the heating element 120 is consistent with the corresponding slope of the preset temperature curve; if the second coincidence threshold is outside the second preset range, it indicates that the actual slope tangent and the preset slope tangent are significantly different, and it can be determined that the actual temperature change rate of the heating element 120 does not meet the corresponding slope of the preset temperature curve.

[0048] S406 , when the target of the second temperature control method is achieved, the second temperature control method is switched back to the first temperature control method to control the temperature of the heating element 120 .

[0049] In these embodiments, in S405, when the processor 1322 of the temperature control unit 132 determines that the actual temperature change rate of the heating element 120 does not match the corresponding slope of the preset temperature curve, the processor 1322 may switch the current first temperature control mode to the second temperature control mode, and regulate the electric energy delivered by the heating unit 131 to the heating element 120 based on the second temperature control mode, thereby achieving the regulation of the actual temperature change rate of the heating element 120, so that the actual temperature change rate of the heating element 120 matches the corresponding slope on the preset temperature curve. Based on this, in S406, when the processor 1322 of the temperature control unit 132 completes the regulation of the actual temperature change rate of the heating element 120 based on the second temperature control mode, that is, when the actual temperature change rate of the heating element 120 matches the corresponding slope of the preset temperature curve again, the processor 1322 may switch the current second temperature control mode back to the first temperature control mode to control the temperature of the heating element 120, and so on.

[0050] The above embodiments are only preferred implementations of the present application, and they are not the only limitations on the relevant steps of the temperature control method; in this regard, those skilled in the art can flexibly set them according to the actual application scenarios based on the above embodiments. Through the implementation of the above embodiments of the present application, in the early stage of heating the heating element 120 (that is, when the heating time is less than or equal to the preset time), the heating element 120 can be temperature controlled based on the first temperature control method, so that the actual temperature of the heating element 120 is consistent with the corresponding preset temperature on the preset temperature curve; in the later stage of heating the heating element 120 (that is, when the heating time is greater than the preset time), the heating element 120 can still be temperature controlled based on the first temperature control method, but it is necessary to calculate the actual temperature change rate of the heating element 120 in real time, and determine whether the actual temperature change rate is consistent with the preset temperature. If the actual temperature change rate meets the corresponding slope of the preset temperature curve, then the temperature control of the heating element 120 can be kept unchanged based on the first temperature control method. Once the actual temperature change rate does not meet the corresponding slope of the preset temperature curve, the current first temperature control method needs to be switched to the second temperature control method, and the heating element 120 is temperature controlled based on the second temperature control method, so that the actual temperature change rate meets the corresponding slope of the preset temperature curve, and then the second temperature control method is switched back to the first temperature control method to control the temperature of the heating element 120, and the cycle is repeated. It can be seen that the present application sets two temperature control modes for the heating element 120. These two temperature control modes can be switched in real time according to specified conditions during the heating process of the heating element 120, thereby improving the dynamic response speed to the temperature change of the heating element 120, and making the actual temperature of the heating element 120 and its change rate always consistent with the preset temperature curve, which not only avoids the overshoot phenomenon when the temperature of the heating element 120 rises / falls, but also ensures the uniformity of the heating temperature field of the aerosol generator 110 in the electronic atomization device.
