[0002] The heating-not-burning atomization equipment is a new type of electronic aerosol generating device that can heat the atomizing medium in the aerosol generating product to generate aerosol.

[0003] Among them, in the heat-not-burn atomization device, the heating device is provided with a accommodating cavity, and the aerosol-generating product is heated by being inserted into the accommodating cavity, and the heating is stopped after being pulled out. In order to realize the reliable heating start and stop of the aerosol-generating product, the aerosol-generating product needs to be identified to determine whether the aerosol-generating product reaches the heating position or leaves the heating position.

[0004] The conventional detection method is to use a micro switch, which is arranged in the accommodating cavity. When the aerosol generating product is inserted, the micro switch is triggered, and when the aerosol generating product is pulled out, the micro switch is released for detection.

[0059] A first aspect of an embodiment of the present invention provides an atomization device.

[0060] like Figure 1 As shown, the atomization device includes an aerosol generating product 10 and a device body 20. The device body 20 is used to heat the aerosol generating product 10. The aerosol generating product 10 and the device body 20 are arranged in a plug-in structure. When the aerosol generating product 10 is inserted into the device body 20 and reaches the heating position, the device body 20 starts heating, and when the aerosol generating product 10 is pulled out of the heating position, the device body 20 stops heating. An atomizing medium is arranged in the aerosol generating product 10, and the atomizing medium generates an aerosol when being heated.

[0061] Among them, the device body 20 is provided with a accommodating cavity 21 for accommodating the aerosol generating product 10, and the accommodating cavity 21 has an opening for inserting and removing the aerosol generating product 10. The device body 20 is also provided with a heating circuit 22 for heating the aerosol generating product 10. The shape of the accommodating cavity 21 is adapted to the aerosol generating product 10. For example, when the aerosol generating product 10 is a columnar structure, the accommodating cavity 21 is also set to a columnar structure, and the internal size of the accommodating cavity 21 is larger than the size of the aerosol generating product 10 and the size is close to that of the aerosol generating product 10, so as to perform a limiting effect when the aerosol generating product 10 is inserted and removed.

[0062] The accommodating cavity 21 is a hollow structure, and the accommodating cavity 21 can be generated by surrounding thin sheets of corresponding materials. For example, a metal thin sheet is surrounded by welding, clamping, etc. to form an accommodating cavity 21, and an opening is left at one end of the accommodating cavity 21 for plugging and unplugging the aerosol generating product 10.

[0063] Alternatively, the accommodating cavity 21 may also be generated by opening a hole on the corresponding substrate, for example, the accommodating cavity 21 may be generated on a metal substrate by deposition, punching, etc., and the hole opening is the opening of the accommodating cavity 21 .

[0064] The heating circuit 22 is specifically arranged relative to the accommodating chamber 21 according to the structure of the aerosol generating product 10 and the installation position of the atomizing medium, and can be arranged at a corresponding position on the inner wall, bottom or outside of the accommodating chamber 21 .

[0065] When the heating circuit 22 is arranged at the bottom of the accommodating cavity 21, when the aerosol generating product 10 reaches the heating position, the heating circuit 22 directly heats the aerosol generating product 10; and, when the heating circuit 22 is arranged outside the accommodating cavity 21 and relative to the bottom of the accommodating cavity 21, when the aerosol generating product 10 reaches the heating position, the heating circuit 22 indirectly heats the aerosol generating product 10 through the cavity of the accommodating cavity 21.

[0066] The device body 20 may be a fixed device structure, or a portable device. Optionally, the device body 20 further includes a shell, and the heating circuit 22 is disposed in the shell.

[0067] The outer shell is formed by surrounding a sheet of corresponding material, and includes a shell and an upper cover that are adapted to be installed. The upper cover is provided with an opening at an opening position relative to the accommodating cavity 21. For the convenience of maintenance, the shell and the upper cover are detachably installed.

[0068] In order to simplify the detection structure of the aerosol generating product 10 and improve the application scenarios, in this embodiment, the atomization device also includes a magnetic induction component 30, the magnetic induction component 30 includes a magnet 31 and a magnetic sensitive device 32, the magnet 31 and the magnetic sensitive device 32 are respectively arranged relative to the aerosol generating product 10 and the device body 20, and the magnetic sensitive device 32 is connected to the heating circuit 22.

[0069] The magnetic sensing device 32 is configured to sense the magnitude of the magnetic field of the magnet 31 when the aerosol generating article 10 is inserted or removed, and output a corresponding electrical signal to the heating circuit 22 .

[0070] The heating circuit 22 is configured to determine the position state of the aerosol generating article 10 according to the received electrical signal, and start heating when the aerosol generating article 10 is inserted and stop heating when the aerosol generating article 10 is pulled out.

[0071] In this embodiment, the magnet 31 and the magnetic sensitive device 32 can be respectively arranged on the aerosol generating product 10 and the device body 20, that is, the magnet 31 can be arranged on the aerosol generating product 10, and the magnetic sensitive device 32 is arranged on the device body 20, or the magnet 31 is arranged on the device body 20, and the magnetic sensitive device 32 is arranged on the aerosol generating product 10.

[0072] When the aerosol generating product 10 is inserted into the accommodating cavity 21 of the device body 20 and reaches the heating position, the magnet 31 and the magnetic sensitive device 32 are arranged relative to or in contact with each other at a preset distance, and the magnetic sensitive device 32 triggers the output of a first electrical signal to the heating circuit 22. When the heating circuit 22 receives the first electrical signal, it determines that the aerosol generating product 10 is inserted and reaches the heating position. The heating circuit 22 starts the heating operation and heats the aerosol generating product 10.

[0073] When the aerosol generating product 10 leaves the heating position of the device body 20, the relative distance between the magnet 31 and the magnetic sensitive device 32 increases or separates, and the magnetic sensitive device 32 triggers the output of the second electrical signal or stops outputting the first electrical signal to the heating circuit 22. When the heating circuit 22 receives the second electrical signal or does not receive the first electrical signal, the heating circuit 22 determines that the aerosol generating product 10 is pulled out and leaves the heating position, and the heating circuit 22 stops heating the aerosol generating product 10.

[0074] Among them, the magnetic sensitive device 32 and the magnet 31 can be set inside or outside the atomization device, and the magnet 31 and the magnetic sensitive device 32 are matched and set in preset positions. For example, the magnetic sensitive device 32 is set on the inner side of the upper cover of the device body 20, and the magnet 31 is set at the position of the aerosol generating product 10 relative to the magnetic sensitive device 32.

[0075] In an alternative embodiment, if Figure 1 As shown, optionally, the aerosol generating article 10 includes an aerosol generating substrate segment 11 and a fixing portion 12 disposed on the aerosol generating substrate segment 11, and the aerosol generating substrate segment 11 and the fixing portion 12 are arranged crosswise;

[0076] The aerosol generating substrate section 11 includes a medium section and a filter section, wherein the medium section is provided with an atomizing medium, and the filter section is provided with a filter element for filtering out impurities;

[0077] The magnet 31 is disposed on the fixing portion 12 , and the magnetic sensitive device 32 is disposed on the device body 20 and is disposed opposite to the magnet 31 .

[0078] In this embodiment, the aerosol generating matrix segment 11 and the fixing portion 12 are cross-arranged. When the aerosol generating product 10 is extended along the first direction, the fixing portion 12 is arranged along the second direction. The first direction and the second direction are cross-arranged at a preset angle. In an optional embodiment, the preset angle is 90 degrees. A through hole can be set in the middle of the fixing portion 12, and the aerosol generating matrix segment 11 is fixed through the through hole, or the outside of the two are fixed by bonding, clamping, etc., and the specific fixing method is not limited.

[0079] The size of the fixing portion 12 along the second direction is the same as or different from the size of the upper cover body of the device body 20. When the aerosol generating product 10 is inserted into the accommodating cavity 21, the fixing portion 12 overlaps with the upper cover portion. The magnet 31 and the magnetic sensitive device 32 are arranged at the overlapping portion of the outer shell and the fixing portion 12. The two can be located on the same center line along the first direction, or at different positions.

[0080] The magnet 31 can be disposed inside the fixing portion 12 or on the surface of the fixing portion 12 . In order to reduce the gap between the fixing portion 12 and the upper cover, when disposed on the surface of the fixing portion 12 , the outer surface of the magnet 31 is flush with the surface of the fixing portion 12 .

[0081] Correspondingly, the magnetic sensitive device 32 can be arranged inside the shell or on the surface of the upper cover. Similarly, in order to reduce the gap between the fixing part 12 and the upper cover, when the magnetic sensitive device 32 is arranged on the surface of the upper cover, the outer surface of the magnetic sensitive device 32 is flush with the outer surface of the upper cover.

[0082] When the aerosol generating matrix segment 11 is inserted into the accommodating cavity 21 of the device body 20 and reaches the heating position, the magnet 31 arranged on the fixing part 12 is arranged relative to or in contact with the magnetic sensitive device 32 at a preset distance, and the magnetic sensitive device 32 triggers the output of a first electrical signal to the heating circuit 22. When the heating circuit 22 receives the first electrical signal, it determines that the aerosol generating product 10 is inserted and reaches the heating position, and the heating circuit 22 starts the heating operation and heats the aerosol generating product 10.

[0083] When the aerosol generating product 10 leaves the heating position of the device body 20, the relative distance between the magnet 31 arranged on the fixing part 12 and the magnetic sensitive device 32 increases or separates, and the magnetic sensitive device 32 triggers the output of the second electrical signal or stops the output of the first electrical signal to the heating circuit 22. When the heating circuit 22 receives the second electrical signal or does not receive the first electrical signal, the heating circuit 22 determines that the aerosol generating product 10 is pulled out and leaves the heating position, and the heating circuit 22 stops heating the aerosol generating product 10.

[0084] In another alternative embodiment, if Figure 2 As shown, the magnet 31 is arranged on the device body 20, the magnetic sensing device 32 is arranged on the fixing part 12, the magnetic sensing device further includes a first metal contact 41 and a second metal contact 42, the first metal contact 41 is arranged on the device body 20, the second metal contact 42 is arranged on the fixing part 12, the magnetic sensing device 32 is connected to the second metal contact 42, the first metal contact 41 is connected to the heating circuit 22 and is arranged opposite to the second metal contact 42;

[0085] The first metal contact 41 and the second metal contact 42 are in contact when the aerosol-generating substrate segment 11 is inserted into the heating position.

[0086] In this embodiment, the magnetic sensitive device 32 is arranged on the fixed part 12, the magnet 31 is arranged in the device body 20, and the magnet 31 and the magnetic sensitive device 32 are arranged at the overlapping part of the outer shell and the fixed part 12. The two can be located on the same center line along the first direction, or at different positions.

[0087] The magnet 31 can be set inside the device body 20, or set on the surface of the device body 20. In order to reduce the gap between the fixing part 12 and the upper cover, when set on the surface of the device body 20, the outer surface of the magnet 31 is flush with the surface of the upper cover of the device body 20.

[0088] Correspondingly, the magnetic sensitive device 32 can be arranged inside or on the surface of the fixing part 12. Similarly, in order to reduce the gap between the fixing part 12 and the upper cover, when the magnetic sensitive device 32 is arranged on the surface of the fixing part 12, the outer surface of the magnetic sensitive device 32 is flush with the outer surface of the fixing part 12.

[0089] The first metal contact 41 and the second metal contact 42 are respectively arranged on the surface of the device body 20 and the fixed part 12. When the aerosol generating matrix segment 11 is inserted into the accommodating cavity 21 of the device body 20 and reaches the heating position, the magnetic sensitive device 32 arranged on the fixed part 12 is arranged relative to or in contact with the magnet 31 at a preset distance. The magnetic sensitive device 32 triggers the output of a first electrical signal. The first electrical signal is output to the heating circuit 22 through the second metal contact 42 and the first metal contact 41. When receiving the first electrical signal, the heating circuit 22 determines that the aerosol generating product 10 is inserted and reaches the heating position. The heating circuit 22 starts the heating operation and heats the aerosol generating product 10.

[0090] When the aerosol generating product 10 moves away from the heating position of the device body 20, the relative distance between the magnet 31 and the magnetic sensitive device 32 arranged on the device body 20 increases or separates, and the magnetic sensitive device 32 triggers the output of the second electrical signal or cuts off the output of the first electrical signal. The second electrical signal is output to the heating circuit 22 through the second metal contact 42 and the first metal contact 41, or no electrical signal is output to the heating circuit 22. When the heating circuit 22 receives the second electrical signal or does not receive the electrical signal, the heating circuit 22 determines that the aerosol generating product 10 is pulled out and moves away from the heating position, and the heating circuit 22 stops heating the aerosol generating product 10.

[0091] The fixing portion 12 is in a strip-shaped structure, and the aerosol generating product 10 is disposed in the middle of the fixing portion 12. When a user uses the atomizing device, the aerosol generating product 10 may be inserted in two directions. In order to detect the position state of the aerosol generating product 10 when the aerosol generating product 10 is inserted in different directions, Figure 1 and Figure 2 As shown, optionally, the magnet 31 includes two magnets 31, and the two magnets 31 are symmetrically arranged on both sides of the fixing portion 12;

[0092] The magnetic sensitive device 32 is disposed on the device body 20 and is disposed opposite to the magnet 31;

[0093] Alternatively, the two magnets 31 are respectively disposed on two sides of the device body 20 , and the magnetic sensitive device 32 is disposed on one side of the fixing portion 12 and opposite to the magnets 31 .

[0094] When the magnet 31 is arranged on the fixing part 12, the two magnets 31 are symmetrically arranged relative to the aerosol generating matrix segment 11, and the magnetic sensitive device 32 is arranged on the device body 20. When the aerosol generating product 10 is inserted in two different directions, the magnetic sensitive device 32 can be arranged relative to or directly contact one of the magnets 31 at a preset distance. Therefore, when the aerosol generating product 10 is inserted and removed, the heating circuit 22 can detect the change state of the aerosol generating product 10, thereby starting or stopping heating.

[0095] Alternatively, when the magnets 31 are arranged on the device body 20, the two magnets 31 are symmetrically arranged relative to the accommodating cavity 21, and the magnetic sensitive device 32 is arranged on one side of the fixing portion 12. When the aerosol generating product 10 is inserted in two different directions, the magnetic sensitive device 32 can be arranged relative to or directly contact one of the magnets 31 at a preset distance. Therefore, when the aerosol generating product 10 is inserted and removed, the heating circuit 22 can detect the change state of the aerosol generating product 10, thereby starting or stopping heating.

[0096] The magnetic sensitive device 32 may be a component that is sensitive to a magnetic field. In an optional embodiment, the magnetic sensitive device 32 includes a Hall switch 321 or an analog Hall sensor 322 .

[0097] The heating circuit 22 may use a corresponding control unit and a heating unit, such as Figure 3 As shown, optionally, the heating circuit 22 includes:

[0098] a heating assembly 222 configured to heat the aerosol-generating article 10;

[0099] The control circuit 221 is connected to the heating component 222 and the magnetic sensitive device 32 respectively. The control circuit 221 is configured to determine the position state of the aerosol generating article 10 according to the received electrical signal, and to trigger the heating component 222 to start heating when the aerosol generating article 10 is inserted, and to trigger the heating component 222 to stop heating when the aerosol generating article 10 is pulled out.

[0100] In this embodiment, the heating component 222 is specifically arranged relative to the accommodating chamber 21 according to the structure of the aerosol generating product 10 and the installation position of the atomizing medium. It can be arranged at a position corresponding to the inner wall, bottom or outside of the accommodating chamber 21. Optionally, the accommodating chamber 21 has a columnar structure, and the heating component 222 is located at the bottom of the accommodating chamber 21, or is arranged outside the accommodating chamber 21 and relative to the bottom of the accommodating chamber 21.

[0101] When the heating component 222 is disposed at the bottom of the accommodating cavity 21, when the aerosol generating product 10 reaches the heating position, the heating component 222 directly heats the aerosol generating product 10; and, when the heating component 222 is disposed outside the accommodating cavity 21 and relative to the bottom of the accommodating cavity 21, when the aerosol generating product 10 reaches the heating position, the heating component 222 indirectly heats the aerosol generating product 10 through the cavity of the accommodating cavity 21.

[0102] The heating component 222 can be a heating element, such as a resistance heating component, a heating component 222 composed of a magnetic core and a heating coil, etc., and the specific structure is not limited.

[0103] The control circuit 221 may include a controller, a processor, a driving circuit, and the like.

[0104] The power supply source of the control circuit 221, the heating component 222, and the magnetic sensitive device 32 can be provided by the corresponding power module. The power module can be set in the device body 20 or set independently from the device body 20. The specific setting method of the power module is not limited.

[0105] The control circuit 221 and the power module can be arranged on the same circuit board, or can be arranged separately, and the specific arrangement method is not limited.

[0106] When the aerosol generating product 10 is inserted into the accommodating cavity 21 of the device body 20 and reaches the heating position, the magnet 31 and the magnetic sensitive device 32 are arranged relative to or in contact with each other at a preset distance, and the magnetic sensitive device 32 triggers the output of a first electrical signal to the control circuit 221. When the control circuit 221 receives the first electrical signal, it determines that the aerosol generating product 10 is inserted and reaches the heating position, triggers the heating component 222 to start the heating work, and heats the aerosol generating product 10.

[0107] When the aerosol generating product 10 leaves the heating position of the device body 20, the relative distance between the magnet 31 and the magnetic sensitive device 32 increases or separates, and the magnetic sensitive device 32 triggers the output of the second electrical signal or stops outputting the first electrical signal to the control circuit 221. When the control circuit 221 receives the second electrical signal or does not receive the first electrical signal, the control circuit 221 determines that the aerosol generating product 10 is pulled out and leaves the heating position, and the control circuit 221 triggers the heating component 222 to stop heating the aerosol generating product 10.

[0108] In an alternative embodiment, if Figure 4 As shown, the magnetic sensitive device 32 includes a Hall switch 321;

[0109] The control circuit 221 includes a pull-up circuit 2211 and a processor 2212. The pull-up circuit 2211 is connected to the Hall switch 321 and the processor 2212 respectively. The processor 2212 is also connected to the heating component 222.

[0110] The Hall switch 321 is configured to output a low level signal to the processor 2212 through the pull-up circuit 2211 when the aerosol generating article 10 is inserted, and to output a high level signal to the processor 2212 through the pull-up circuit 2211 when the aerosol generating article 10 is unplugged;

[0111] The processor 2212 is configured to trigger the heating component 222 to start heating when receiving a low-level signal, and to trigger the heating component 222 to stop heating when receiving a high-level signal.

[0112] In this embodiment, the Hall switch 321 is a device that is sensitive to magnetic fields. When the Hall switch 321 is in a magnetic field of a certain intensity, the Hall effect will cause changes in its own output signal. The Hall switch 321 detects the presence or absence of the magnet 31, thereby detecting the position state of the aerosol generating product 10 relative to the device body 20, and determining whether the aerosol generating product 10 is inserted or removed.

[0113] Among them, when the aerosol generating product 10 is inserted into the accommodating cavity 21 of the device body 20 and reaches the heating position, the magnet 31 and the Hall switch 321 are arranged relative to or in contact with each other at a preset distance, and the Hall switch 321 triggers the output of a low-level signal to the control circuit 221. When receiving the low-level signal, the control circuit 221 determines that the aerosol generating product 10 is inserted and reaches the heating position, triggers the heating component 222 to start the heating work, and heats the aerosol generating product 10.

[0114] When the aerosol generating product 10 leaves the heating position of the device body 20, the relative distance between the magnet 31 and the Hall switch 321 increases or separates, and the Hall switch 321 triggers the default output of a high-level signal to the control circuit 221. When the control circuit 221 receives the high-level signal, the control circuit 221 determines that the aerosol generating product 10 is pulled out and leaves the heating position, and the control circuit 221 triggers the heating component 222 to stop heating the aerosol generating product 10.

[0115] The pull-up circuit 2211 is used to pull up the signal when the Hall switch 321 is not triggered, so as to ensure that the control circuit 221 receives a high-level signal. The pull-up circuit 2211 can use a corresponding pull-up resistor, a bias circuit, etc. Figure 5 As shown, optionally, the pull-up circuit 2211 includes a first resistor R1;

[0116] A first end of the first resistor R1 is connected to the positive power supply terminal VCC, and a second end of the first resistor R1 , a signal output end of the Hall switch 321 , and a signal end of the processor 2212 are connected.

[0117] Among them, the Hall switch 321 also includes a power supply end and a ground end. The power supply end is connected to the positive power supply end VCC. The voltage signal of the positive power supply end VCC can be provided by the corresponding power supply module. At the same time, the power supply end is also connected to a filter capacitor C1 for filtering out clutter on the voltage signal to avoid clutter signals interfering with the Hall switch 321 and causing the Hall switch 321 to be triggered incorrectly.

[0118] like Figure 6 As shown, in another optional embodiment, the sensitive device includes an analog Hall sensor 322;

[0119] The control circuit 221 includes an analog-to-digital conversion circuit 2213 and a processor 2212. The analog-to-digital conversion circuit 2213 is connected to the Hall sensor and the processor 2212 respectively. The processor 2212 is also connected to the heating component 222.

[0120] an analog Hall sensor 322 configured to output a first analog signal to the analog-to-digital conversion circuit 2213 when the aerosol generating article 10 is inserted, and to output a second analog signal to the analog-to-digital conversion circuit 2213 when the aerosol generating article 10 is removed;

[0121] The analog-to-digital conversion circuit 2213 is configured to perform analog-to-digital conversion on the analog signal output by the analog Hall sensor 322, and output a corresponding first digital signal and a second digital signal;

[0122] The processor 2212 is configured to trigger the heating component 222 to start heating when receiving the first digital signal, and to trigger the heating component 222 to stop heating when receiving the second digital signal.

[0123] In this embodiment, the triggering principle of the analog Hall sensor 322 is the same as that of the Hall switch 321. When the analog Hall sensor 322 is in a certain magnetic field strength, the Hall effect will cause the output signal to change. By changing the output signal of the analog Hall sensor 322, it is detected whether the aerosol generating product 10 is inserted or unplugged. The difference is that the output signal of the analog Hall sensor 322 is an analog signal.

[0124] That is, when the aerosol generating product 10 is inserted, the analog Hall sensor 322 triggers the output of the first analog signal to the analog-to-digital conversion circuit 2213. After receiving the first analog signal, the analog-to-digital conversion circuit 2213 performs analog-to-digital conversion and converts and outputs the first digital signal to the processor 2212. When the processor 2212 receives the first digital signal, it determines the high and low states of the first digital signal, and determines that the aerosol generating product 10 is inserted and reaches the heating position. The processor 2212 triggers the heating component 222 to start heating.

[0125] When the aerosol generating product 10 is unplugged, the analog Hall sensor 322 outputs a second analog signal to the analog-to-digital conversion circuit 2213, and the analog-to-digital conversion circuit 2213 converts and outputs a second digital signal to the processor 2212. When the processor 2212 receives the second digital signal, it determines the high and low states of the second digital signal and determines that the aerosol generating product 10 is unplugged, and the processor 2212 triggers the heating component 222 to stop heating.

[0126] The analog-to-digital conversion circuit 2213 may adopt a corresponding analog-to-digital converter, an operational amplifier circuit, and the like. Figure 7 As shown, optionally, the analog-to-digital conversion circuit 2213 includes a second resistor R2, a third resistor R3, a fourth resistor R4 and an operational amplifier OPA;

[0127] The first end of the second resistor R2, the first end of the third resistor R3 and the non-inverting input terminal of the operational amplifier OPA are connected, the second end of the second resistor R2 is grounded, the second end of the third resistor R3 is connected to the positive power supply terminal VCC, the inverting input terminal of the operational amplifier OPA is connected to the signal output terminal of the analog Hall sensor 322, the output terminal of the operational amplifier OPA, the first end of the fourth resistor R4 and the signal terminal of the processor 2212 are connected, and the second end of the fourth resistor R4 is connected to the positive power supply terminal VCC.

[0128] In this embodiment, the analog signal output by the analog Hall sensor 322 is converted into a digital signal output through the operational amplifier OPA, and the processor 2212 determines whether the analog Hall sensor 322 is triggered by judging the high and low states of the digital signal, and then determines whether the aerosol generating product 10 is inserted or removed.

[0129] At the same time, the voltages of the operational amplifier OPA and the positive power supply terminal VCC may be provided by corresponding power supply modules.

[0130] Similarly, the analog Hall sensor 322 also includes a power supply terminal and a ground terminal. The power supply terminal is connected to the positive power supply terminal VCC. The voltage signal of the positive power supply terminal VCC can be provided by the corresponding power supply module. At the same time, the power supply terminal is also connected to a filter capacitor C1 for filtering out noise on the voltage signal to prevent the noise signal from interfering with the Hall switch 321 and causing the analog Hall sensor 322 to be falsely triggered.

[0131] like Figure 8 As shown, in another optional embodiment, the sensitive device includes an analog Hall sensor 322;

[0132] The control circuit 221 includes a processor 2212, and a signal terminal of the processor 2212 is connected to a signal output terminal of the analog Hall sensor 322;

[0133] The analog Hall sensor 322 is configured to output an analog signal of a corresponding magnitude when the aerosol generating article 10 is inserted or removed;

[0134] The processor 2212 is configured to compare the analog signal with a preset analog signal, and determine that the aerosol generating article 10 is inserted when the analog signal is greater than the preset analog signal, and trigger the heating component 222 to start heating;

[0135] And when the analog signal is less than the preset analog signal, it is determined that the aerosol generating article 10 is pulled out, and the heating component 222 is triggered to stop heating.

[0136] In this embodiment, the processor 2212 directly receives the analog signal output by the analog Hall sensor 322, and has a preset analog signal built in. The processor 2212 detects the voltage of the output signal of the analog Hall sensor 322 through the AD detection pin. When it is detected that the output analog signal exceeds the preset analog signal, it is confirmed that the analog Hall sensor 322 is triggered, and it is determined that the aerosol generating product 10 is inserted, and the processor 2212 triggers the heating component 222 to start heating. When it is detected that the output analog signal does not exceed the preset analog signal, the processor 2212 determines that the analog Hall sensor 322 is not triggered, and it is determined that the aerosol generating product 10 is unplugged, and the processor 2212 triggers the heating component 222 to stop heating.
