In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0050] A first aspect of an embodiment of the present invention provides a heating device.

[0051] like Figure 1 As shown, the heating device is used to heat the aerosol generating product 10. The aerosol generating product 10 and the heating device are arranged in a plug-in structure. When the aerosol generating product 10 is inserted into the heating device and reaches the heating position, the heating device starts heating, and when the aerosol generating product 10 is pulled out of the heating position, the heating device stops heating. An atomizing medium is arranged in the aerosol generating product 10, and the atomizing medium generates an aerosol when it is heated.

[0052] Among them, the heating device includes a heating mechanism 20, which 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 heating mechanism 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.

[0053] 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.

[0054] 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 .

[0055] 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 .

[0056] 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.

[0057] The heating mechanism 20 may be a fixed device structure, or a portable device. Optionally, the heating mechanism 20 further includes a shell, and the heating circuit 22 is disposed in the shell.

[0058] 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.

[0059] In order to simplify the detection structure of the aerosol generating product 10 and improve the application scenarios, in the present embodiment, the heating device also includes an infrared component 30, the infrared component 30 includes an infrared emitting component 31 and an infrared receiving component 32, the infrared emitting component 31 and the infrared receiving component 32 are preset relative to each other on the heating mechanism 20, and the infrared receiving component 32 is also connected to the heating circuit 22.

[0060] The infrared emitting assembly 31 is configured to emit an infrared signal in a preset direction, wherein the preset direction is a plugging and unplugging direction of the aerosol generating article 10 or a direction crossing the plugging and unplugging direction;

[0061] The infrared receiving component 32 is configured to receive infrared signals of corresponding magnitudes and convert and output corresponding electrical signals to the heating circuit 22;

[0062] The heating circuit 22 is configured to determine the position state of the aerosol generating article 10 according to the size of the 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.

[0063] In this embodiment, the infrared emitting component 31 and the infrared receiving component 32 are arranged adjacent to or opposite to the heating mechanism 20, and are arranged in the plugging and unplugging direction of the aerosol generating product 10 or in the cross direction of the plugging and unplugging direction. A groove can be opened in the cavity wall of the accommodating cavity 21, and the infrared emitting component 31 and the infrared receiving component 32 are arranged adjacent to or opposite to each other in the groove. The infrared emitting component 31 and the infrared receiving component 32 are arranged toward the accommodating cavity 21, that is, toward the cross direction of the plugging and unplugging direction of the aerosol generating product 10, and perform the sending and receiving of infrared signals.

[0064] The infrared emitting component 31 and the infrared receiving component 32 can also be arranged on the upper cover of the heating mechanism 20, and an opening can be provided on the upper cover. The infrared emitting component 31 and the infrared receiving component 32 are arranged adjacent to the aerosol generating product 10, that is, they are arranged in the plugging and unplugging direction of the aerosol generating product 10, and perform the sending and receiving of infrared signals.

[0065] When the aerosol generating product 10 is gradually inserted from the outside along the direction of the containing cavity 21, the strength of the reflected infrared signal changes due to the change in the position of the aerosol generating product 10 relative to the containing cavity 21, for example Figure 1As shown, before insertion, an infrared signal is emitted to the other side wall of the accommodating cavity 21, and is reflected back to the infrared receiving component 32 from the other side wall. At this time, the infrared receiving component 32 outputs a second electrical signal to the heating circuit 22. When the heating circuit 22 receives the second electrical signal, it determines that the aerosol generating product 10 is not inserted. At this time, the heating circuit 22 does not start the heating operation; and when the aerosol generating product 10 is inserted into the accommodating cavity 21 of the heating device and reaches the heating position, an infrared signal is emitted to the aerosol generating product 10 and is reflected back to the infrared receiving component 32 from the aerosol generating product 10. At this time, the reflected infrared signal is stronger, and the infrared receiving component 32 outputs a first electrical signal to the heating circuit 22. After receiving the changed second electrical signal and 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.

[0066] Similarly, when the aerosol generating product 10 is in the initial state of being pulled out, the infrared signal is reflected from the aerosol generating product 10 back to the infrared receiving component 32, and the infrared receiving component 32 outputs a first electrical signal to the heating circuit 22. When the aerosol generating product 10 leaves the heating position during the pulling out process, the infrared signal is emitted to the other side wall of the accommodating cavity 21, and is reflected from the other side wall back to the infrared receiving component 32, and the infrared receiving component 32 converts and outputs a second electrical signal to the heating circuit 22. After receiving the changed first electrical signal and the second 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.

[0067] Among them, when the infrared emitting component 31 and the infrared receiving component 32 are arranged in the groove of the corresponding heating device, a transparent cover is also provided at the opening position of the groove. The transparent cover can transmit infrared light and prevent dust and dirt, thereby preventing the infrared emitting component 31 and the infrared receiving component 32 from being contaminated.

[0068] Among them, the infrared emitting component 31 and the infrared receiving component 32 can use corresponding infrared emitting tubes 311 and infrared receiving tubes 321, and can also use corresponding driving circuits. The infrared signal can be emitted continuously or at a preset frequency, and the specific emission method is not limited.

[0069] The infrared emitting component 31 may be connected to the heating circuit 22 or to another driving unit, and the specific connection object is not limited.

[0070] like Figure 2 As shown, in an optional embodiment, the infrared emitting component 31 includes an infrared emitting tube 311, a first resistor R1, a second resistor R2, a third resistor R3 and an electronic switch tube Q1;

[0071] A first end of the first resistor R1 is connected to the positive power supply terminal VCC, a second end of the first resistor R1 is connected to a first end of the infrared emitting tube 311, a second end of the infrared emitting tube 311 is connected to a first end of the electronic switch tube Q1, a control end of the electronic switch tube Q1, a first end of the second resistor R2 and a first end of the third resistor R3 are connected, a second end of the second resistor R2 constitutes a signal input end LED_TX of the infrared emitting component 31 and is configured to receive an emission control signal, a second end of the third resistor R3 and a second end of the electronic switch tube Q1 are grounded;

[0072] The infrared receiving component 32 includes an infrared receiving tube 321, a fourth resistor R4 and a fifth resistor R5;

[0073] The first end of the fourth resistor R4 is connected to the positive power supply terminal VCC, the second end of the fourth resistor R4 is connected to the first end of the infrared receiving tube 321, the second end of the infrared receiving tube 321 is connected to the first end of the fifth resistor R5 to form the signal output terminal LED_RX of the infrared receiving component 32, and the second end of the fifth resistor R5 is grounded.

[0074] In this embodiment, the emission control signal is normally at a low level. When detection is required, the emission control signal is switched to a pulse signal with an adjustable pulse width, that is, the infrared emission component 31 emits a pulse signal with a preset duty cycle at a preset frequency to the electronic switch tube Q1, and the electronic switch tube Q1 is turned on and off correspondingly at the preset frequency and the preset duty cycle, thereby driving the infrared emission tube 311 to emit an infrared signal at the same frequency and duty cycle. When the infrared receiving tube 321 is within the monitorable range, the infrared receiving tube 321 passes a current of a certain intensity and generates a voltage signal of the same frequency and corresponding magnitude at the first end of the fifth resistor R5, and the magnitude of the voltage signal is related to the intensity of the infrared signal received by the infrared receiving tube 321.

[0075] In an alternative embodiment, if Figure 3 and Figure 4 As shown, the infrared transmitting tube 311 and the infrared receiving tube 321 are adjacently arranged in a cavity wall on one side of the accommodating cavity 21 .

[0076] In this embodiment, before insertion, an infrared signal is emitted to the other side wall of the accommodating cavity 21 and is reflected back to the infrared receiving tube 321 from the other side wall. At this time, the infrared receiving tube 321 outputs a second voltage signal to the heating circuit 22. When the heating circuit 22 receives the second voltage signal, it determines that the aerosol generating product 10 is not inserted. At this time, the heating circuit 22 does not start the heating operation. When the aerosol generating product 10 is inserted into the accommodating cavity 21 of the heating device and reaches the heating position, the infrared signal is emitted to the aerosol generating product 10 and is reflected back to the infrared receiving tube 321 from the aerosol generating product 10. At this time, the reflected infrared signal is stronger, and the infrared receiving tube 321 outputs a first voltage signal to the heating circuit 22. After receiving the changed second voltage signal and the first voltage 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.

[0077] Similarly, when the aerosol generating product 10 is in the initial state of being pulled out, the infrared signal is reflected from the aerosol generating product 10 back to the infrared receiving tube 321, and the infrared receiving tube 321 outputs a first voltage signal to the heating circuit 22. When the aerosol generating product 10 leaves the heating position during the pulling out process, the infrared signal is emitted to the other side wall of the accommodating cavity 21, and is reflected from the other side wall back to the infrared receiving tube 321, and the infrared receiving tube 321 converts and outputs a second voltage signal to the heating circuit 22. After receiving the changed first voltage signal and the second voltage 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.

[0078] Among them, when the infrared emitting tube 311 and the infrared receiving tube 321 are arranged in the groove of the corresponding heating device, a transparent cover is also provided at the opening position of the groove. The transparent cover can transmit infrared light and prevent dust and dirt, thereby preventing the infrared emitting tube 311 and the infrared receiving tube 321 from being contaminated.

[0079] In another alternative embodiment, if Figure 5 and Figure 6 As shown, 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;

[0080] The infrared transmitting tube 311 and the infrared receiving tube 321 are disposed on the heating mechanism 20 and transmit and receive infrared signals toward the fixing portion 12 .

[0081] 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.

[0082] 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 heating mechanism 20. When the aerosol generating product 10 is inserted into the accommodating cavity 21, the fixing portion 12 overlaps with the upper cover portion, and the infrared component 30 is arranged at the overlapping portion of the outer shell and the fixing portion 12.

[0083] The infrared component 30 can be arranged inside the housing or on the surface of the upper cover. Similarly, in order to reduce the gap between the fixing portion 12 and the upper cover, when the infrared component 30 is arranged on the surface of the upper cover, the outer surface of the infrared component 30 is flush with the outer surface of the upper cover.

[0084] Before insertion, the infrared signal is emitted to the aerosol generating product 10 that is farther away, and is reflected back to the infrared receiving tube 321 from the farther aerosol generating product 10. At this time, the infrared receiving tube 321 outputs a second voltage signal to the heating circuit 22. When the heating circuit 22 receives the second voltage signal, it determines that the aerosol generating product 10 is not inserted. At this time, the heating circuit 22 does not start the heating operation. When the aerosol generating product 10 is inserted into the accommodating cavity 21 of the heating device and reaches the heating position, the infrared signal is emitted to the nearby aerosol generating product 10. At this time, the detection distance is close to 0, and the infrared signal is reflected back to the infrared receiving tube 321 from the aerosol generating product 10. At this time, the reflected infrared signal is stronger, and the infrared receiving tube 321 outputs a first voltage signal to the heating circuit 22. After receiving the changed second voltage signal and the first voltage 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.

[0085] Similarly, when the aerosol generating product 10 is in the initial state of being pulled out, the infrared signal is reflected from the aerosol generating product 10 back to the infrared receiving tube 321, and the infrared receiving tube 321 outputs a first voltage signal to the heating circuit 22. When the aerosol generating product 10 leaves the heating position during the pulling out process, the infrared signal is emitted to the aerosol generating product 10 that is getting farther away, and is reflected back to the infrared receiving tube 321 from the aerosol generating product 10 at the far end. The intensity of the infrared signal decreases, and the infrared receiving tube 321 converts and outputs a second voltage signal to the heating circuit 22. After receiving the changed first voltage signal and the second voltage 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.

[0086] Among them, when the infrared emitting tube 311 and the infrared receiving tube 321 are arranged in the groove of the corresponding heating device, a transparent cover is also provided at the opening position of the groove. The transparent cover can transmit infrared light and prevent dust and dirt, thereby preventing the infrared emitting tube 311 and the infrared receiving tube 321 from being contaminated.

[0087] When the infrared transmitting tube 311 and the infrared receiving tube 321 are adjacently arranged for left-right reflection or up-down reflection, the heating circuit 22 determines the insertion or removal state of the aerosol generating article 10 according to the magnitude of the received voltage signal, and sets a judgment threshold therein and compares it with the corresponding voltage signal. In an optional embodiment, the heating circuit 22 is specifically configured as follows:

[0088] Before the position state detection, a first voltage signal output by the infrared receiving component 32 when the aerosol generating article 10 is inserted is obtained, and a second voltage signal output by the infrared receiving component 32 when the aerosol generating article 10 is removed is obtained, and a preset voltage signal is determined based on the first voltage signal and the second voltage signal, and the preset voltage signal is greater than the second voltage signal and less than the first voltage signal;

[0089] During position state detection, the voltage signal output by the infrared receiving component 32 is obtained and compared with the preset voltage signal. When the voltage signal is less than the preset voltage signal, it is determined that the aerosol generating product 10 is in the unplugged state; and when the voltage signal is greater than the preset voltage signal, it is determined that the aerosol generating product 10 is in the inserted state.

[0090] In this embodiment, the heating circuit 22 has two working states, including state correction and state detection, wherein the state correction occurs before the position state detection of the aerosol generating product 10, which can be a pre-factory calibration process or a pre-use calibration process. The heating circuit 22 detects the voltage signal output by the infrared receiving component 32 at a preset frequency. At this time, the aerosol generating product 10 is inserted manually or automatically, and the heating circuit 22 obtains the current first voltage signal and stores it. Then, the aerosol generating product 10 is unplugged, and the current second voltage signal is detected and obtained and stored.

[0091] Then, the heating circuit 22 determines a preset voltage signal based on the first voltage signal and the second voltage signal. The preset voltage signal is a signal between the first voltage signal and the second voltage signal. The preset voltage signal may be:

[0092] Vf=Vo2+K*(Vo1-Vo2);

[0093] Vf represents a preset voltage signal, Vo1 represents a first voltage signal, Vo2 represents a second voltage signal, K represents a proportionality coefficient, and K is greater than 0.

[0094] The magnitude of the preset voltage signal changes accordingly according to the change of the K value.

[0095] During status detection, that is, when the atomization device is used, when the heating circuit 22 detects that the voltage signal output by the infrared receiving component 32 is less than the preset voltage signal, it is determined that the aerosol generating product 10 is in the unplugged state; and when it is detected that the voltage signal output by the infrared receiving component 32 is greater than the preset voltage signal, it is determined that the aerosol generating product 10 is in the inserted state, and the heating of the aerosol generating product 10 is started or stopped accordingly.

[0096] When the infrared emitting tube 311 and the infrared receiving tube 321 are adjacently arranged for left-right reflection or up-down reflection, the heating circuit 22, in another optional embodiment, is specifically configured as follows:

[0097] Before the position state detection, a first voltage signal output by the infrared receiving component 32 when the aerosol generating article 10 is inserted is obtained, and a preset voltage signal is determined based on the first voltage signal, and the preset voltage signal is less than the first voltage signal;

[0098] During position state detection, the voltage signal output by the infrared receiving component 32 is obtained and compared with the preset voltage signal. When the voltage signal is less than the preset voltage signal, it is determined that the aerosol generating product 10 is in the unplugged state; and when the voltage signal is greater than the preset voltage signal, it is determined that the aerosol generating product 10 is in the inserted state.

[0099] In this embodiment, the heating circuit 22 also has two working states, including state correction and state detection, wherein the state correction occurs before the position state detection of the aerosol generating product 10, which can be a pre-factory calibration process or a pre-use calibration process. The heating circuit 22 detects the voltage signal output by the infrared receiving component 32 at a preset frequency. At this time, the aerosol generating product 10 is inserted manually or automatically, and the heating circuit 22 obtains the current first voltage signal and stores it.

[0100] Then, the heating circuit 22 determines a preset voltage signal based on the first voltage signal, where the preset voltage signal has a difference with the first voltage signal, wherein the preset voltage signal may be:

[0101] Vf=Vo1-△V;

[0102] Vf represents a preset voltage signal, Vo1 represents a first voltage signal, △V represents a small voltage difference, and △V is greater than 0.

[0103] The magnitude of the preset voltage signal changes accordingly according to the change of the ΔV value.

[0104] During status detection, that is, when the atomization device is used, when the heating circuit 22 detects that the voltage signal output by the infrared receiving component 32 is less than the preset voltage signal, it is determined that the aerosol generating product 10 is in the unplugged state; and when it is detected that the voltage signal output by the infrared receiving component 32 is greater than the preset voltage signal, it is determined that the aerosol generating product 10 is in the inserted state, and the heating of the aerosol generating product 10 is started or stopped accordingly.

[0105] In another alternative embodiment, if Figure 7 and Figure 8 As shown, the infrared transmitting tube 311 and the infrared receiving tube 321 are arranged in opposite side walls of the accommodating cavity 21 relative to each other.

[0106] In this embodiment, before insertion, an infrared signal is transmitted to the infrared receiving component 32 of the cavity wall on the other side of the accommodating cavity 21, and the infrared receiving tube 321 outputs a second voltage signal to the heating circuit 22. When the heating circuit 22 receives the second voltage signal, it determines that the aerosol generating product 10 is not inserted. At this time, the heating circuit 22 does not start the heating operation. When the aerosol generating product 10 is inserted into the accommodating cavity 21 of the heating device and reaches the heating position, the infrared signal is transmitted to the aerosol generating product 10. At this time, the infrared signal is blocked by the aerosol generating product 10, and the size of the infrared signal is close to zero. The infrared receiving tube 321 outputs a first voltage signal to the heating circuit 22. After receiving the changed second voltage signal and the first voltage 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.

[0107] Similarly, when the aerosol generating product 10 is in the initial state of being pulled out, a small infrared signal or no infrared signal is transmitted to the infrared receiving tube 321, and the infrared receiving tube 321 outputs a first voltage signal to the heating circuit 22. When the aerosol generating product 10 leaves the heating position during the process of being pulled out, the infrared signal is transmitted to the infrared receiving component 32 on the other side wall of the accommodating cavity 21, and the infrared receiving tube 321 converts and outputs a second voltage signal to the heating circuit 22. After receiving the changed first voltage signal and the second voltage 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.

[0108] Among them, when the infrared emitting tube 311 and the infrared receiving tube 321 are relatively arranged in the grooves of the two side walls of the corresponding accommodating cavity 21, a transparent cover is also provided at the opening position of the groove. The transparent cover can transmit infrared light and prevent dust and dirt, thereby preventing the infrared emitting tube 311 and the infrared receiving tube 321 from being contaminated.

[0109] Corresponding to the left and right direct irradiation mode, the heating circuit 22 determines the insertion or removal state of the aerosol generating article 10 according to the magnitude of the received voltage signal, and sets a judgment threshold therein and compares it with the corresponding voltage signal. Optionally, the heating circuit 22 is specifically configured as follows:

[0110] Before the position state detection, a first voltage signal output by the infrared receiving component 32 when the aerosol generating article 10 is inserted is obtained, and a second voltage signal output by the infrared receiving component 32 when the aerosol generating article 10 is removed is obtained, and a preset voltage signal is determined based on the first voltage signal and the second voltage signal, and the preset voltage signal is greater than the first voltage signal and less than the second voltage signal;

[0111] During position state detection, the voltage signal output by the infrared receiving component 32 is obtained and compared with a preset voltage signal. When the voltage signal is less than the preset voltage signal, it is determined that the aerosol generating product 10 is in an inserted state, and when the voltage signal is greater than the preset voltage signal, it is determined that the aerosol generating product 10 is in a pulled-out state.

[0112] In this embodiment, the heating circuit 22 has two working states, including state correction and state detection, wherein the state correction occurs before the position state detection of the aerosol generating product 10, which can be a pre-factory calibration process or a pre-use calibration process. The heating circuit 22 detects the voltage signal output by the infrared receiving component 32 at a preset frequency. At this time, the aerosol generating product 10 is inserted manually or automatically, and the heating circuit 22 obtains the current first voltage signal and stores it. Then, the aerosol generating product 10 is unplugged, and the current second voltage signal is detected and obtained and stored.

[0113] Then, the heating circuit 22 determines a preset voltage signal based on the first voltage signal and the second voltage signal. The preset voltage signal is a signal between the first voltage signal and the second voltage signal. The preset voltage signal may be:

[0114] Vf=Vo1+K*(Vo2-Vo1);

[0115] Vf represents a preset voltage signal, Vo1 represents a first voltage signal, Vo2 represents a second voltage signal, K represents a proportionality coefficient, and K is greater than 0.

[0116] The magnitude of the preset voltage signal changes accordingly according to the change of the K value.

[0117] During status detection, that is, when the atomization device is used, when the heating circuit 22 detects that the voltage signal output by the infrared receiving component 32 is less than the preset voltage signal, it is determined that the aerosol generating product 10 is in the inserted state, and when it is detected that the voltage signal output by the infrared receiving component 32 is greater than the preset voltage signal, it is determined that the aerosol generating product 10 is in the unplugged state, and the heating of the aerosol generating product 10 is started or stopped accordingly.

[0118] Corresponding to the left and right direct radiation mode, the heating circuit 22 determines the insertion or removal state of the aerosol generating product 10 according to the magnitude of the received voltage signal, and has a judgment threshold set therein and compares it with the corresponding voltage signal.

[0119] In another optional embodiment, the heating circuit 22 is specifically configured as follows:

[0120] Before the position state detection, a first voltage signal output by the infrared receiving component 32 when the aerosol generating article 10 is inserted is obtained, and a preset voltage signal is determined based on the first voltage signal, and the preset voltage signal is greater than the first voltage signal;

[0121] During position state detection, the voltage signal output by the infrared receiving component 32 is obtained and compared with a preset voltage signal. When the voltage signal is less than the preset voltage signal, it is determined that the aerosol generating product 10 is in an inserted state, and when the voltage signal is greater than the preset voltage signal, it is determined that the aerosol generating product 10 is in a pulled-out state.

[0122] In this embodiment, the heating circuit 22 also has two working states, including state correction and state detection, wherein the state correction occurs before the position state detection of the aerosol generating product 10, which can be a pre-factory calibration process or a pre-use calibration process. The heating circuit 22 detects the voltage signal output by the infrared receiving component 32 at a preset frequency. At this time, the aerosol generating product 10 is inserted manually or automatically, and the heating circuit 22 obtains the current first voltage signal and stores it.

[0123] Then, the heating circuit 22 determines a preset voltage signal based on the first voltage signal, where the preset voltage signal has a difference with the first voltage signal, wherein the preset voltage signal may be:

[0124] Vf=Vo1+△V;

[0125] Vf represents a preset voltage signal, Vo1 represents a first voltage signal, △V represents a small voltage difference, and △V is greater than 0.

[0126] The magnitude of the preset voltage signal changes accordingly according to the change of the ΔV value.

[0127] During status detection, that is, when the atomization device is used, when the heating circuit 22 detects that the voltage signal output by the infrared receiving component 32 is less than the preset voltage signal, it is determined that the aerosol generating product 10 is in the inserted state, and when it is detected that the voltage signal output by the infrared receiving component 32 is greater than the preset voltage signal, it is determined that the aerosol generating product 10 is in the unplugged state, and the heating of the aerosol generating product 10 is started or stopped accordingly.

[0128] The heating circuit 22 may use a corresponding control unit and a heating unit, such as Fig. 9 As shown, optionally, the heating circuit 22 includes:

[0129] a heating assembly 222 configured to heat the aerosol-generating article 10;

[0130] The control circuit 221 is connected to the heating component 222 and the infrared receiving component 32 respectively. The control circuit 221 is configured to determine the position state of the aerosol generating product 10 according to the received electrical signal, and to trigger the heating component 222 to start heating when the aerosol generating product 10 is inserted, and to trigger the heating component 222 to stop heating when the aerosol generating product 10 is pulled out.

[0131] 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.

[0132] 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.

[0133] 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.

[0134] The control circuit 221 may include a controller, a processor, a driving circuit, and the like.

[0135] The power supply source of the control circuit 221, the heating component 222, and the infrared receiving component 32 can be provided by the corresponding power module. The power module can be set in the heating mechanism 20 or set independently from the heating mechanism 20. The specific setting method of the power module is not limited.

[0136] 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.

[0137] When the aerosol generating product 10 is inserted into the accommodating cavity 21 of the heating mechanism 20 and reaches the heating position, the infrared receiving component 32 outputs a first electrical signal to the control circuit 221. When receiving the first electrical 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.

[0138] When the aerosol generating product 10 leaves the heating position of the heating mechanism 20, the infrared receiving component 32 triggers the output of a second electrical signal to the control circuit 221. After receiving the second 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.

At the same time, the heating device also includes an infrared component 30, and the infrared component 30 includes an infrared emitting component 31 and an infrared receiving component 32. The infrared emitting component 31 and the infrared receiving component 32 are preset relative to each other on the heating mechanism 20. When the aerosol generating product 10 is inserted into or pulled out of the heating device, the output electrical signal of the infrared receiving component 32 changes. The heating circuit 22 determines the insertion or removal state of the aerosol generating product 10 according to the size of the received electrical signal, and starts or stops heating accordingly. The infrared component 30 can be set at a position corresponding to the aerosol generating product 10 facing the heating device. It has a simple structure, is easy to implement, and has a wide range of application scenarios, not limited to the type of atomization equipment.
