Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to an electronic atomization device and its control method. Background Technology

[0002] Electronic atomizing devices generally include a battery assembly and an atomizing assembly. The atomizing assembly stores an atomizing medium, which generates an edible aerosol when heated. The battery assembly powers the atomizing assembly to heat the atomizing medium stored within it.

[0003] Currently, there are electronic atomizing devices on the market with replaceable atomizing components. The atomizing medium inside the component can be discarded after use. However, some users still refill the atomizing medium after it runs out. Refilling changes the atomizing medium, which can easily lead to mixing different flavors and cause a power mismatch between the atomizing component and the battery component. This can result in the battery component overheating or the atomizing component leaking, shortening the lifespan of the electronic atomizing device, leading to a poor user experience, and hindering users' recognition of the manufacturer and brand.

[0013] In one embodiment, the step of controlling the detection unit to detect the magnetic parameters of the magnetic unit and output a detection signal includes: when the atomizing component is performing a heating operation, controlling the detection unit to detect the magnetic parameters of the magnetic unit and receiving a first level of the magnetic parameter output, and after a first preset time period, controlling the detection unit to detect the magnetic parameters of the magnetic unit and receiving a second level of the magnetic parameter output; the step of controlling the battery component to perform a corresponding operation based on the detection signal includes: controlling the battery component to stop supplying power to the atomizing component based on the first level and the second level being the same; or, controlling the battery component to continue supplying power to the atomizing component based on the first level and the second level being different.

[0014] In one embodiment, the step of controlling the detection unit to detect the magnetic parameters of the magnetic unit and outputting a detection signal includes:

[0015] When the atomizing component is performing a heating operation, the control detection unit detects the magnetic parameters of the magnetic unit and receives the first detection signal output by the magnetic parameters.

[0016] The steps for controlling the battery assembly to perform corresponding operations based on the detection signal include:

[0017] Based on the first detection signal, if the pressure difference remains constant within a second preset time period, control the battery assembly to stop supplying power to the atomizing assembly; or, based on the first detection signal, if the pressure difference gradually decreases and approaches 0 within a second preset time period, control the battery assembly to continue supplying power to the atomizing assembly; wherein, the pressure difference is the difference between the first detection signal and the output result of the detection unit when no magnetic parameter is detected.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0029] Please see Figure 1 , Figure 1This is a schematic diagram of an embodiment of the electronic atomizing device provided in this application. Specifically, the electronic atomizing device includes an atomizing component 10 and a battery component 20 electrically connected, wherein the battery component 20 supplies power to the atomizing component 10 to enable the atomizing component 10 to perform a heating operation. In this application, a magnetic unit 11 is provided within the atomizing component 10, and a detection unit 21 and a controller 22 connected to the detection unit 21 are provided within the battery component 20. Specifically, the detection unit 21 is used to detect the magnetic parameters of the magnetic unit 11 when the atomizing component 10 is performing a heating operation, and output a detection signal; the controller 22 controls the battery component 20 to perform corresponding operations based on the detection signal.

[0030] The magnetic unit 11 can be a magnet or other magnetic object, and the detection unit 21 can output a detection signal based on the magnetic parameters, such as a voltage signal, current signal, level signal, magnetic flux signal, etc.

[0031] The control battery assembly 20 can perform corresponding operations to control the battery assembly 20 to continue / stop supplying power to the atomizing assembly 10; or to increase / decrease the driving power of the battery assembly 20 to the atomizing assembly 10; or to issue alarm prompts, such as audible and visual prompts, vibration prompts, etc.

[0032] In one example, the controller 22 determines that the atomizing component 10 is normal based on the detection signal. Normal operation of the atomizing component 10 includes compatibility between the atomizing component 10 and the battery component 20, and that the atomizing component 10 has not been repeatedly filled with liquid. In this application, when the atomizing component 10 is performing a heating operation, the controller 22 within the battery component 20 determines that the atomizing component 10 is normal based on the detection signal output by the detection unit 21. When the atomizing component 10 is normal, the controller controls the battery component 20 to perform corresponding operations, such as continuing to supply power to the atomizing component 10, or increasing the driving power of the battery component 20 to the atomizing component 10 to ensure the user's inhalation.

[0033] Taking the controller 22's judgment of atomizing component 10 malfunction based on detection signals as an example, malfunctions of atomizing component 10 include incompatibility between atomizing component 10 and battery component 20, and repeated liquid filling of atomizing component 10. In this application, when atomizing component 10 is performing a heating operation, the controller 22 within battery component 20 determines whether atomizing component 10 is malfunctioning based on the detection signal output by detection unit 21. When atomizing component 10 is malfunctioning, the controller controls battery component 20 to perform corresponding operations, such as stopping power supply to atomizing component 10, reducing the driving power of battery component 20 to atomizing component 10, or issuing alarm prompts such as audible and visual prompts or vibration prompts. This avoids situations where battery component 20 overheats or atomizing component 10 leaks due to incompatibility between battery component 20 and atomizing component 10, thus shortening the lifespan of the electronic atomizing device and the user experience. Furthermore, it prevents the mixing of atomizing components 10 and battery components 20 from different brands, hindering users' recognition of manufacturers and brands.

[0034] In some embodiments, the detection unit 21 includes a magnetic head or a Hall sensor, whichever can detect the magnetic parameters of the magnetic unit 11.

[0035] The following description uses a Hall sensor as an example.

[0036] In one embodiment, the detection unit 21 is a switch-type Hall sensor. When the atomizing component 10 is performing a heating operation, the detection unit 21 detects the magnetic parameters of the magnetic unit 11 and outputs a first level based on the magnetic parameters. Simultaneously, the battery component 20 continuously heats the atomizing component. After a first preset time period, the detection unit 21 detects the magnetic parameters of the magnetic unit 11 and outputs a second level based on the magnetic parameters. The controller 22 determines that the atomizing component 10 is abnormal based on the first level and the second level being the same, and controls the battery component 20 to stop supplying power to the atomizing component 10; alternatively, the controller 22 determines that the atomizing component 10 is normal based on the first level and the second level being different, and controls the battery component 20 to continue supplying power to the atomizing component 10.

[0037] In this system, one of the first and second voltage levels is high, and the other is low.

[0038] See Figure 2 and Figure 3 , Figure 2 A schematic diagram of the detection signal output by the detection unit 21 when the magnetic field polarity of the magnetic unit 11 provided in this application is S-shaped; Figure 3 This is a schematic diagram of the detection signal output by the detection unit 21 when the magnetic field polarity of the magnetic unit 11 provided in this application is N-type. Taking the magnetic field polarity of the magnetic unit 11 as an example, as... Figure 2 As shown, when the magnetic induction intensity of magnetic unit 11 exceeds the operating point BOP The detection unit 21 outputs a low level when the magnetic induction intensity of the magnetic unit 11 drops to the action point B. OP With action point B RP During this period, the detection unit 21 outputs a low level that remains unchanged, and the magnetic induction intensity of the magnetic unit 11 drops to the action point B. RP When the detection unit 21 outputs a detection signal that transitions from a low level to a high level, the detection unit 21, utilizing the working principle of a switch-type Hall sensor, detects the magnetic parameters of the magnetic unit 11 within the atomizing component 10 after the battery assembly 20 is electrically connected to and supplies power to the atomizing component 10. If the magnetic parameters are detected, the detection unit 21 outputs a low-level (first level) detection signal, and the battery assembly 20 supplies power to the atomizing component 10 and heats it. It is understandable that the magnetic parameters (e.g., magnetism) of the magnetic unit 11 decrease with increasing temperature. During initial heating, the temperature is relatively low, and the magnetic parameters of the magnetic unit 11 decrease less. The detection unit 21 maintains a low-level detection signal output, meaning the battery assembly 20 continuously supplies power to the atomizing component 10. As heating continues and the temperature gradually increases, the magnetic parameters of the magnetic unit 11 decrease more. When the magnetic parameter decreases to the threshold (B) of the detection unit 21, the signal transitions to a high level. RP When the detection unit 21 outputs a high-level (second level) detection signal, the controller 22 considers the heating to be effective based on the transition signal from the low-level detection signal to the high-level detection signal output by the detection unit 21, and controls the battery assembly 20 to continuously supply power to the atomizing assembly 10 for atomization.

[0039] It should be noted that during the atomization process, as the temperature continues to increase, the magnetism of the magnetic unit 11 will disappear once the temperature of the magnetic unit 11 reaches the Curie point. Therefore, during the next use, the detection unit 21 in the battery assembly 20 cannot detect the magnetic parameters of the magnetic unit 11 in the atomization component 10, and the detection unit 21 outputs a continuously high-level detection signal. The first level is the same as the second level, that is, the detection signal output by the detection unit 21 does not change from low to high at this time. The controller 22 considers that there is an abnormality in the heating, such as that the atomization component 10 has been used and refilled, or that the atomization component 10 is incompatible with the battery assembly 20. In order to avoid the battery assembly 20 overheating or the atomization component 10 leaking, thus shortening the service life of the electronic atomization device and affecting the user experience, the controller 22 controls the battery assembly 20 to perform corresponding operations.

[0040] Understandably, in the electronic atomizing device provided in this application, after the battery assembly 20 supplies power to the atomizing assembly 10 and the atomizing assembly 10 is heated, the magnetic unit 11 built into the atomizing assembly 10 loses its magnetism due to being heated to the Curie point temperature, and this is an irreversible state. Therefore, the magnetic unit 11 no longer has magnetism. Thus, even if liquid is refilled into the atomizing assembly 10, at the initial heating stage, the detection unit 21 will not detect the magnetic parameters of the magnetic unit 11 and will output a second level. If the controller 22 does not detect a jump from the first level to the second level in the level signal output by the detection unit 21 within a certain period of time, it will consider that there is an abnormality in the atomizing assembly 10 and perform corresponding operations. This can avoid situations such as the battery assembly 20 overheating or the atomizing assembly 10 leaking liquid, thereby improving the user experience. Alternatively, when replacing the atomizing component 10 with one that is incompatible with the battery component 20, since the atomizing component 10 does not have a magnetic unit 11, the detection unit 21 will not be able to detect the magnetic parameters of the magnetic unit 11 and will output the second level continuously. If the controller 22 does not detect the high-to-low transition of the level signal output by the detection unit 21 within a certain period of time, it will consider that the atomizing component 10 is abnormal and perform the corresponding operation.

[0041] In one embodiment, the detection unit 21 is a linear Hall sensor. When the atomizing assembly 10 is in a heating state, the detection unit 21 detects the magnetic parameters of the magnetic unit 11 and outputs a first detection signal based on the magnetic parameters. The controller 22 determines that the pressure difference remains constant within a second preset time period based on the first detection signal and controls the battery assembly 20 to stop supplying power to the atomizing assembly 10; or, the controller 22 determines that the pressure difference gradually decreases and approaches 0 within the second preset time period based on the first detection signal and controls the battery assembly 20 to continue supplying power to the atomizing assembly 10; wherein, the pressure difference is the difference between the first detection signal and the output result of the detection unit 21 when no magnetic parameters are detected.

[0042] See Figure 4 , Figure 4This is a schematic diagram of another embodiment of the detection signal output by the detection unit 21 provided in this application. The detection unit 21 is a linear Hall sensor. When the magnetic unit 11 has S-type magnetism, as the magnetism decays, the first detection signal U1 output by the detection unit 21 gradually decreases. Furthermore, as the temperature of the magnetic unit 11 reaches the Curie point, the magnetism of the magnetic unit 11 disappears, and the first detection signal U1 decreases to u / 2. When the magnetic unit 11 has N-type magnetism, as the magnetism decays, the first detection signal U1 output by the detection unit 21 gradually increases. Furthermore, as the temperature of the magnetic unit 11 reaches the Curie point, the magnetism of the magnetic unit 11 disappears, and the first detection signal U1 increases to u / 2. Here, u / 2 is the midpoint between the maximum voltage value represented by the first detection signal U1 output by the detection unit 21 under S-type magnetism and the minimum voltage value represented by the first detection signal U1 output by the detection unit 21 under N-type magnetism. Utilizing the working principle of a linear Hall effect sensor, after the battery assembly 20 is electrically connected to the atomizing assembly 10 and supplies power to the atomizing assembly 10, the detection unit 21 within the battery assembly 20 detects the magnetic parameters of the magnetic unit 11 within the atomizing assembly 10. If a magnetic parameter is detected, a first detection signal U1 is output, and the battery assembly 20 is controlled to heat the atomizing assembly 10. The controller 22 considers the heating effective if the pressure difference between the first detection signal U1 and the detection result output by the detection unit 21 when no magnetic parameter is detected gradually decreases and approaches 0 within a second preset time. At this time, the controller 22 controls the battery assembly 20 to continuously supply power to the atomizing assembly 10. Wherein, the output result of the detection unit 21 when no magnetic parameter is detected is u / 2, then the pressure difference |U|=|U1-u / 2|. If |U| gradually decreases and approaches 0, the heating is considered effective, and the controller 22 controls the battery assembly 20 to continuously heat the atomizing assembly 10.

[0043] It should be noted that during the atomization process, as the temperature continues to increase, the magnetism of the magnetic unit 11 will disappear once the temperature of the magnetic unit 11 reaches the Curie point. Therefore, in the next use, the detection unit 21 in the battery assembly 20 will not be able to detect the magnetic parameters of the magnetic unit 11 in the atomization assembly 10, and the output result of the first detection signal output by the detection unit 21 will remain unchanged, i.e., |U| will also remain unchanged. The controller 22 will consider that there is an abnormality in the heating, such as the atomization assembly 10 has been used and refilled, or the atomization assembly 10 is incompatible with the battery assembly 20. In order to avoid the battery assembly 20 overheating or the atomization assembly 10 leaking, which would shorten the service life of the electronic atomization device and affect the user experience, the controller 22 will control the battery assembly 20 to perform corresponding operations.

[0044] Understandably, in the electronic atomizing device provided in this application, after the battery assembly 20 supplies power to the atomizing assembly 10 and the atomizing assembly 10 is heated, the magnetic unit 11 built into the atomizing assembly 10 loses its magnetism due to being heated to the Curie point temperature, and this loss is irreversible. Therefore, the magnetic unit 11 no longer has magnetism. Thus, even if the atomizing assembly 10 is refilled with liquid or replaced with an atomizing assembly 10 that is incompatible with the battery assembly 20, at the initial stage of heating, the output of the detection unit 21 remains at the second level, and the controller 22 cannot detect the level signal output by the detection unit 21 within the first preset time period. A sudden change from low to high indicates an abnormality in the atomizing component, prompting the corresponding operation. Alternatively, if the detection unit 21 fails to detect the magnetic parameters of the magnetic unit 11 and the output of the first detection signal U1 remains unchanged, and the controller 22 fails to detect the first detection signal, the pressure difference between the first detection signal and the detection result output when the detection unit 21 fails to detect the magnetic parameters gradually decreases and approaches 0 within a second preset time period, indicating an abnormality in the atomizing component 10, prompting the corresponding operation. This can prevent the battery component 20 from overheating or the atomizing component 10 from leaking, thus improving the user experience.

[0045] See Figure 5 , Figure 5 This is a schematic diagram of another embodiment of the electronic atomizing device provided in this application; wherein, the atomizing assembly 10 further includes a heating element R, which is used to generate heat under energized conditions to atomize the substrate to be atomized. To achieve the effect of the controller 22 controlling the battery assembly 20 to stop / continue supplying power to the heating element R, the battery assembly 20 further includes a battery 23 and a first switch Q1, wherein the battery 23 stores electrical energy; the first switch Q1 is connected to the path between the battery 23 and the heating element R, and is turned on or off based on the control of the controller 22. That is, the first switch Q1 selectively turns on or off the power supply path between the battery 23 and the heating element R based on the control of the controller.

[0046] In this application, the first switch Q1 can be a relay or a MOSFET. Specifically, this application uses a MOSFET as an example. The first terminal of the first switch Q1 is connected to the battery 23, the second terminal is connected to the heating element R, and the control terminal is connected to the controller 22. The control terminal of the first switch Q1 receives the PWM signal output by the controller 22 and selectively turns on or off the power supply path between the battery 23 and the heating element R.

[0047] In one embodiment, the battery assembly 20 further includes a second switch Q2 connected in the path between the battery 23 and the controller 22, used to connect or disconnect the electrical connection between the battery 23 and the controller 22. Specifically, to avoid power loss on the internal components of the electronic atomizing device when it is not in use, i.e., in standby mode, in standby mode, the user or the controller 22 can control the second switch to disconnect the electrical connection between the battery 23 and the controller 22, thereby avoiding power loss on the controller and improving the battery 23's battery life. When the user uses the electronic atomizing device, since the controller 22 is not working, the user can manually control the second switch to connect the electrical connection between the battery 23 and the controller 22, thereby allowing normal use of the electronic atomizing device.

[0048] Of course, in other embodiments, the battery assembly 20 may also include other components, such as a charging management chip and a charging interface, the specific structure and function of which are the same as those in the prior art, and will not be described in detail here.

[0049] Please see Figure 6 , Figure 6 A flowchart illustrating an embodiment of the control method for the electronic atomizing device provided in this application specifically includes:

[0050] Step S1: Control the detection unit to detect the magnetic parameters of the magnetic unit and output the detection signal.

[0051] Specifically, when the battery assembly supplies power to the atomizing assembly to enable the atomizing assembly to perform a heating operation, the detection unit detects the magnetic parameters of the magnetic unit and outputs a corresponding detection signal.

[0052] The magnetic unit can be a magnet or other magnetic object, and the detection unit includes a magnetic head or a Hall sensor, as long as it can detect the magnetic parameters of the magnetic unit. The detection signal output by the detection unit based on the magnetic parameters can be a voltage signal, current signal, level signal, magnetic flux signal, etc.

[0053] Step S2: Control the battery assembly to perform corresponding operations based on the detection signal.

[0054] Controlling the battery assembly to perform corresponding operations can be to control whether the battery assembly continues or stops supplying power to the atomizing component; or it can be to increase or decrease the driving power of the battery assembly to the atomizing component; or it can issue alarm prompts, such as audible and visual prompts, vibration prompts, etc.

[0055] Taking the controller's determination of the atomizing component's normal operation based on detection signals as an example, normal operation of the atomizing component includes matching the atomizing component with the battery component and the atomizing component not being refilled with liquid. In this application, when the atomizing component is performing a heating operation, the controller within the battery component determines that the atomizing component is normal based on the detection signal output by the detection unit. Furthermore, when the atomizing component is normal, the controller controls the battery component to perform corresponding operations, such as continuing to supply power to the atomizing component or increasing the driving power of the battery component to the atomizing component to ensure the user's inhalation.

[0056] Taking the controller's judgment of atomizing component malfunction based on detection signals as an example, atomizing component malfunctions include incompatibility between the atomizing component and the battery component, and repeated liquid filling of the atomizing component. In this application, when the atomizing component is performing a heating operation, the controller within the battery component determines whether the atomizing component is malfunctioning based on the detection signal output by the detection unit. When the atomizing component is malfunctioning, the controller controls the battery component to perform corresponding operations, such as stopping the battery component from supplying power to the atomizing component, reducing the battery component's driving power to the atomizing component, and issuing alarm prompts, such as audible and visual prompts, and vibration prompts. This avoids situations where battery component mismatch leads to battery component overheating or atomizing component leakage, shortening the lifespan of the electronic atomizing device and affecting the user experience. Furthermore, it prevents the mixing of atomizing components and battery components from different brands, thus avoiding obstacles to user recognition of manufacturers and brands.

[0057] In one embodiment of this application, step S1 includes: while the atomizing component is performing a heating operation, controlling the detection unit to detect the magnetic parameters of the magnetic unit and receiving a first level output by the magnetic parameters; and after a first preset time period, controlling the detection unit to detect the magnetic parameters of the magnetic unit and receiving a second level output by the magnetic parameters. Step S2 includes: based on the first level and the second level being the same, controlling the battery component to stop supplying power to the atomizing component; or, based on the first level and the second level being different, controlling the battery component to continue supplying power to the atomizing component.

[0058] Specifically, the detection unit in this embodiment is a switch-type Hall sensor. When the atomizing component is in the heating state, the detection unit detects the magnetic parameters of the magnetic unit and outputs a first level based on the magnetic parameters. Simultaneously, the battery assembly continuously heats the atomizing component. After a first preset time period, the detection unit detects the magnetic parameters of the magnetic unit and outputs a second level based on the magnetic parameters. If the first and second levels are the same, the controller determines that the atomizing component is abnormal and controls the battery assembly to stop supplying power to the atomizing component; alternatively, if the first and second levels are different, the controller determines that the atomizing component is normal and controls the battery assembly to continue supplying power to the atomizing component.

[0059] Taking an S-shaped magnetic field polarity of the magnetic unit as an example, after the battery assembly is electrically connected to the atomizing assembly and supplies power to the atomizing assembly, the detection unit within the battery assembly detects the magnetic parameters of the magnetic unit within the atomizing assembly. If the magnetic parameters are detected, the detection unit outputs a low-level (first level) detection signal, and the battery assembly supplies power to the atomizing assembly and heats it. Understandably, the magnetic parameters (e.g., magnetism) of the magnetic unit decay as temperature increases. During initial heating, the temperature is relatively low, and the decay of the magnetic parameters is small. The detection unit maintains a low-level detection signal, meaning the battery assembly continuously supplies power to the atomizing assembly. As heating continues and the temperature gradually rises, the decay of the magnetic parameters of the magnetic unit increases. When the decay of the magnetic parameters reaches the detection unit's transition point (B... RP When the detection unit outputs a high-level (second level) detection signal, the controller considers the heating to be valid based on the transition signal from the low-level detection signal to the high-level detection signal output by the detection unit, and controls the battery assembly to continuously supply power to the atomizing assembly for atomization.

[0060] It should be noted that during atomization, as the temperature continues to rise, the magnetic unit loses its magnetism once it reaches the Curie point. Therefore, during subsequent uses, the detection unit within the battery pack cannot detect the magnetic parameters of the magnetic unit within the atomization component, and the detection unit outputs a consistently high-level detection signal. That is, the detection signal does not transition from low to high, leading the controller to interpret this as an anomaly, such as the atomization component having been used and refilled, or being incompatible with the battery pack. To prevent overheating of the battery pack or leakage of the atomization component, thus shortening the lifespan of the electronic atomization device and affecting the user experience, the controller instructs the battery pack to perform corresponding operations.

[0061] In another embodiment of this application, step S1 includes: when the atomizing component is performing a heating operation, controlling the detection unit to detect the magnetic parameters of the magnetic unit and receiving a first detection signal output by the magnetic parameters. Step S2 includes: based on the first detection signal, determining that the pressure difference remains unchanged within a second preset time period, controlling the battery component to stop supplying power to the atomizing component; or, based on the first detection signal, determining that the pressure difference gradually decreases and approaches 0 within a second preset time period, controlling the battery component to continue supplying power to the atomizing component; wherein, the pressure difference is the difference between the first detection signal and the output result of the detection unit when no magnetic parameters are detected.

[0062] Specifically, the detection unit in this embodiment is a linear Hall sensor. After the battery assembly is electrically connected to the atomizing assembly and supplies power to the atomizing assembly, the detection unit within the battery assembly detects the magnetic parameters of the magnetic unit within the atomizing assembly. If a magnetic parameter is detected, a first detection signal is output, and the battery assembly is controlled to heat the atomizing assembly. The controller considers the heating effective if the voltage difference between the first detection signal and the detection signal output when the detection unit does not detect a magnetic parameter gradually decreases and approaches 0 within a second preset time. At this time, the controller controls the battery assembly to continuously supply power to the atomizing assembly. Wherein, the output result of the detection unit when no magnetic parameter is detected is u / 2, then the voltage difference |U|=|U1-u / 2|, where u / 2 is the midpoint between the maximum voltage value represented by the first detection signal output by the detection unit under S-type magnetism and the minimum voltage value represented by the second detection signal output by the detection unit under N-type magnetism. If |U| gradually decreases and approaches 0, the heating is considered effective, and the controller controls the battery assembly to continuously heat the atomizing assembly.

[0063] Understandably, when the detection unit is a linear Hall sensor and the magnetic unit has S-type magnetism, the first detection signal output by the detection unit gradually decreases as the magnetism decays. Furthermore, as the temperature of the magnetic unit reaches the Curie point, the magnetism disappears, and the first detection signal decreases to u / 2. When the magnetic unit has N-type magnetism, the first detection signal output by the detection unit gradually increases as the magnetism decays. Furthermore, as the temperature of the magnetic unit reaches the Curie point, the magnetism disappears, and the first detection signal increases to u / 2. The controller, based on the pressure difference |U| gradually decreasing and approaching 0 within a second preset time, considers the heating effective and controls the battery assembly to continuously power the atomizing assembly for atomization.

[0064] It should be noted that during the atomization process, as the temperature continues to rise, the magnetic unit loses its magnetism once it reaches the Curie point. Therefore, upon subsequent use, the detection unit within the battery pack cannot detect the magnetic parameters of the magnetic unit within the atomization component. The output of the first detection signal remains unchanged, i.e., |U| also remains unchanged. The controller interprets this as an abnormality in heating, such as the atomization component having been used and refilled, or the component being incompatible with the battery pack. To prevent overheating of the battery pack or leakage of the atomization component, which could shorten the lifespan of the electronic atomization device and negatively impact the user experience, the controller instructs the battery pack to perform corresponding operations.

[0065] The control method for the electronic atomizing device provided in this application, after the battery pack supplies power to the atomizing component and the atomizing component is heated, the magnetic unit built into the atomizing component loses its magnetism due to being heated to the Curie point temperature, and this loss is irreversible. Therefore, the magnetic unit no longer has magnetism. Thus, even when the atomizing component is refilled or replaced with an atomizing component that is incompatible with the battery pack, at the initial stage of heating, the output of the detection unit remains at the second level. The controller cannot detect any low-to-high level transition in the level signal output by the detection unit within a first preset time period, and considers the atomizing component to be abnormal, thereby performing corresponding operations. Alternatively, the output result of the first detection signal remains unchanged because the detection unit cannot detect the magnetic parameters of the magnetic unit. The controller cannot detect that the pressure difference between the first detection signal and the detection result output when the detection unit does not detect the magnetic parameters gradually decreases and approaches 0 within a second preset time period, and considers the atomizing component to be abnormal, thereby performing corresponding operations. This can avoid situations such as the battery pack overheating or the atomizing component leaking, thereby improving the user experience.
