[0032] The technical solution of this embodiment will be further described below with reference to the accompanying drawings and specific implementation methods.

[0033] like Figures 1-4 As shown, the wireless charger in this embodiment includes a housing 10 and a first coil 40. The housing 10 includes a receiving portion 11 and a charging portion 12 that are interconnected. Specifically, in this embodiment, the wireless charger is used to charge an aerosol generating device. The aerosol generating device includes a heating needle for inserting into an aerosol generating article for heating to generate aerosol, a smoke extractor 100 for extracting the aerosol generating article, and a body 200. Optionally, the charging portion 12 can be inserted into the smoke extractor 100, and the smoke extractor 100 can be inserted into the body 200. The first coil 40 is located in the charging portion 12. The aerosol generating device also includes a second coil 120 for inducing eddy currents in the heating needle to generate heat. The first coil 40 and the second coil 120 are coupled so that when alternating current is applied to the first coil 40, an induced current can be generated in the second coil 120. The induced current can flow into the battery of the body 200 in the aerosol generating device for charging.

[0034] Specifically, in this embodiment, the housing 10 includes a charging unit 12, which can be inserted into the cigarette holder 100. The first coil 40 is disposed in the charging unit 12. When AC power is applied to the first coil 40, an induced current is generated in the second coil 120 inside the cigarette holder 100. The induced current flows into the battery of the aerosol generating device to achieve wireless charging. Thus, the simple insertion method facilitates user operation and enables fast charging. At the same time, the second coil 120 inside the cigarette holder 100 can be reused, making reasonable use of the internal space of the housing 10, reducing the compression of the battery compartment space, and reducing costs.

[0035] The specific structure of the wireless charger in this embodiment will be described below.

[0036] like Figure 1 As shown, this embodiment provides a wireless charger that is inserted into an aerosol generating device to achieve wireless charging functionality, replacing the existing USB charging structure. This eliminates the existing charging port, improves space utilization, and reduces the overall size of the device. Figure 2 and Figure 3 As shown, the wireless charger includes a housing 10, which includes a receiving portion 11 and a charging portion 12 that are interconnected. The charging portion 12 can be inserted into a cigarette holder 100, and the cigarette holder 100 can be inserted into the main body 200, thereby achieving a stable connection between the wireless charger and the aerosol generating device. The insertion method is simple and easy to operate, facilitating user use. Furthermore, the receiving portion 11 and the charging portion 12 can form a closed space, effectively ensuring the waterproof performance of the wireless charger and preventing water ingress from affecting its operation. For example, the housing 10 is configured with a T-shaped structure, and the cigarette holder 100 is also configured with a T-shaped structure, with a through hole provided inside the cigarette holder 100. The charging portion 12 of the housing 10 is inserted into the through hole. Furthermore, the outer diameter of the charging portion 12 is adapted to the inner diameter of the through hole in the cigarette holder 100 to ensure stable insertion of the housing 10 into the cigarette holder 100.

[0037] Specifically, the charging unit 12 is equipped with a first coil 40, and the cigarette holder 100 is equipped with a second coil 120. When AC power is applied to the first coil 40, an induced current is generated in the second coil 120. This induced current flows into the battery in the body 200 for charging. Therefore, by placing the second coil 120 in the cigarette holder 100, the distance between it and the first coil 40 can be shortened, thereby improving wireless charging efficiency. Optionally, the second coil 120 can be used as an excitation coil for heating in the cigarette holder 100. When AC power is applied to the first coil 40, the second coil 120 can be reused as a receiving coil for wireless charging, eliminating the need for an additional receiving coil in the aerosol generating device. This allows for efficient use of the internal space of the housing 10, reduces the compression of the battery compartment space, and lowers costs.

[0038] Specifically, a clearance channel 101 is provided at the center of the housing 10 along the axial direction of the housing 10 to avoid the heating needle. An enclosed space surrounds the clearance channel 101 and communicates with it. This ensures that there is no movement interference between the heating needle and the wireless charger, while the hollow design of the housing 10 further facilitates heat dissipation. For example, the clearance channel 101 extends along the axial direction of the housing 10, and the enclosed space extends radially to improve the space utilization rate inside the housing 10.

[0039] like Figure 2 and Figure 3 As shown, the accommodating part 11 is provided with an accommodating cavity 111, and the accommodating cavity 111 is located in a closed space. A first circuit board 20 electrically connected to the first coil 40 is provided. The other end of the first circuit board 20 is connected to a power line 13, and the power line 13 extends out of the accommodating part 11, thereby realizing a stable input of AC power to the first coil 40 through the power line 13.

[0040] like Figure 2 As shown, the wireless charger also includes a shielding film 30, which is located between the clearance channel 101 and the first coil 40. This prevents the heating pin from heating when AC power is applied to the first coil 40 for charging. Exemplarily, the shielding film 30 is a magnetic shielding film; in other embodiments, other materials may be used for shielding as needed.

[0041] Furthermore, the charging unit 12 is provided with an annular cavity 121, which is arranged around the outside of the clearance channel 101. The first coil 40 is located in the annular cavity 121, thereby ensuring the stable placement of the first coil 40. Exemplarily, the shielding film 30 is disposed on the inner wall of the clearance channel 101, on the outside of the heating needle, and / or on the inner wall of the annular cavity 121, on the inside of the first coil 40. The specific arrangement can be selected as needed to avoid motion interference with the heating needle while ensuring the shielding effect of the shielding film 30. Specifically, along the axial direction of the clearance channel 101, the length of the shielding film 30 is greater than the length of the heating needle extending into the clearance channel 101, thereby ensuring that the shielding film 30 is disposed on the outer periphery of the heating needle, improving the shielding effect.

[0042] Combination Figure 2 and Figure 4As shown, in this embodiment, a cooling cavity 501 is also provided inside the housing 10 on the side of the accommodating portion 11 opposite to the charging portion 12. The cooling cavity 501 is used to hold the coolant 50 to meet heat dissipation requirements. Typically, the first coil 40 generates a large amount of heat during operation, and the coolant 50 effectively reduces the heat generated by the first coil 40. Specifically, there is a gap between the surface of the coolant 50 and the top surface of the cooling cavity 501 to allow space for the coolant 50 to expand when heated. For example, the cooling cavity 501 is also configured as a T-shaped cavity, thus located on the top of the housing 10. Furthermore, the size of the cooling cavity 501 matches the size of the accommodating portion 11 so that there are no protrusions on the top and sides of the housing 10, improving the aesthetics of the wireless charger structure while preventing accidental injury to the user during insertion.

[0043] Optionally, the cooling chamber 501 extends to the clearance channel 101, and a partition is provided between the cooling chamber 501 and the clearance channel 101 to achieve adjacent arrangement of the cooling chamber 501 and the clearance channel 101, while isolating the two so that the coolant 50 will not flow into the clearance channel 101, achieving effective heat dissipation while sealing the top of the clearance channel 101 to further enhance the waterproof effect.

[0044] The specific structure of the aerosol generation system in this embodiment will be described below.

[0045] like Figures 1-4As shown, the aerosol generation system includes the aforementioned wireless charger and aerosol generation device. The aerosol generation device includes a heating needle for inserting into the aerosol generation article for heating to generate aerosol, and a second coil 120 for inducing eddy currents in the heating needle to generate heat. The aerosol generation device also includes a smoke extractor 100 and a body 200 for extracting the aerosol generation article. Specifically, the wireless charger is removably connected to the aerosol generation device. When the wireless charger is connected to the aerosol generation device, the charging unit 12 is inserted into the smoke extractor 100. The first coil 40 and the second coil 120 are coupled so that when alternating current is applied to the first coil 40, an induced current is generated in the second coil 120. This induced current flows into the battery of the aerosol generation device for charging. Specifically, when the charging unit 12 is inserted into the cigarette holder 100, the second coil 120 is located outside the first coil 40 and is electrically connected to the battery disposed in the body 200. That is, from the inside to the outside, the components are heating needle, shielding film 30, first coil 40, and second coil 120. When AC power is applied to the first coil 40, an induced current can be generated in the second coil 120 for charging. Specifically, a terminal block 110 is provided between the cigarette lighter 100 and the body 200, and a second circuit board 210 is provided inside the body 200. The second coil 120 is connected to the second circuit board 210 through the terminal block 110, and the second circuit board 210 is connected to the battery of the body 200. Thus, the wireless charger is powered through the power cord 13. The control circuit on the first circuit board 20 converts the input voltage into a high-frequency low voltage. This high-frequency low voltage is applied to the first coil 40. The first coil 40 and the second coil 120 are coupled to each other, thereby generating an induced current in the second coil 120. After being converted and rectified by the second circuit board 210, the induced current finally flows into the battery of the body 200 to complete the charging.
