[0003] This utility model relates to the field of aerosol technology, and in particular to an aerosol generating device. Background Technology

[0004] Traditional tobacco-generating substrates (e.g., cigarettes, cigars, etc.) produce tobacco smoke by burning tobacco during use. Existing technologies offer alternatives to these traditional substrates by releasing compounds through heating without combustion. Examples of such products include aerosol generators, which typically include a heating element and a battery cell to power the heating element. The heating element heats the aerosol-generating substrate to produce an aerosol for the user to inhale. Many aerosol generators have metal casings and complex PCBA (Printed Circuit Board Assembly) structures; therefore, electrostatic discharge (ESD) testing is required for reliability testing to ensure a tight fit between the conductive structure and grounding components, effectively dissipating static electricity from the metal casing.

[0005] Existing aerosol generating devices conduct static electricity by setting conductive structures such as conductive foam, conductive springs, or soldered wires on a PCB board. However, the structural design is complex in order for these conductive structures to come into contact with the metal casing, which can interfere with the internal structural space and assembly of the aerosol generating device and is not conducive to the miniaturization of the product.

[0037] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0038] As shown in Figures 1 to 5, this embodiment provides an aerosol generating device for discharging static electricity from the metal casing 1.

[0039] The aerosol generating device includes a metal shell 1, a housing chamber, a heating element, a PCB board 2, a USB socket 3, and a conductive component 4. The housing chamber is used to house the aerosol generating product, and the heating element is used to heat the aerosol generating product to generate aerosol.

[0040] The heating element may surround the receiving chamber, so that when the aerosol-generating article is received in the receiving chamber, the heat generated by the heating element can be transferred from the side of the aerosol-generating article to the aerosol-generating article, thereby heating the aerosol-generating article. Alternatively, in some embodiments, the heating element may also extend into the receiving chamber, so that when the aerosol-generating article is received in the receiving chamber, at least a portion of the heating element can be inserted into the aerosol-generating article for heating.

[0041] Furthermore, the heating element can heat the aerosol-generated product by means of electromagnetic induction. Specifically, the heating element can be constructed to be passed through by a changing magnetic field, thereby generating heat under the action of eddy current effect and magnetic hysteresis effect; or, the heating element can also use any of the following methods to heat the aerosol-generated product: resistance heating wire, resistance heating film, infrared electrothermal coating, etc.

[0042] Aerosol-generating articles are preferably made of tobacco-containing materials that release volatile compounds from the article upon heating; alternatively, they may be non-tobacco materials suitable for electric heating and smoke generation after heating. Aerosol-generating articles are preferably solid articles, which may include one or more of the following: vanilla leaves, tobacco leaves, homogenized tobacco, expanded tobacco, powder, granules, fragments, strips, or sheets; or, the solid article may contain additional tobacco or non-tobacco volatile flavor compounds to be released upon heating. In some embodiments, the aerosol-generating device may also heat a liquid aerosol-generating article to atomize it and generate an aerosol, the liquid aerosol-generating article containing nicotine and / or flavoring agents and / or aerosol-generating substances (e.g., glycerin).

[0043] Specifically, PCB board 2 is disposed within metal casing 1, with USB connector 3 mounted on PCB board 2 and at least partially exposed for connection to an external power source, thereby enabling external power to supply power to the aerosol generating device. Simultaneously, conductive element 4 is disposed on PCB board 2 and abuts against the inner wall of metal casing 1. After contact with the inner wall of metal casing 1, conductive element 4 enables electrostatic conduction to the metal casing 1. The conductive element 4 is located between PCB board 2 and USB connector 3, allowing PCB board 2, conductive element 4, and USB connector 3 to be stacked sequentially in the vertical space. This ensures that conductive element 4 does not interfere with the internal structural space and assembly of the aerosol generating device, facilitating assembly and promoting miniaturization. Optionally, conductive element 4 is a spring probe. The elastic spring probe provides cushioning when abutting against the inner wall of metal casing 1, maintaining good electrical contact with the metal casing 1 under elastic force while preventing breakage.

[0044] Furthermore, the conductive component 4 is surface-mounted onto the PCB board 2, allowing it to utilize the space on the surface of the PCB board 2 without requiring holes, thus saving installation space, improving circuit performance, and not affecting the installation of other components on the PCB board 2. Simultaneously, the PCB board 2 has a ground terminal, and the conductive component 4 is conductively connected to this ground terminal. This direct conductive connection between the conductive component 4 and the ground terminal of the PCB board 2 eliminates the need for indirect conduction through intermediate electrical connection devices, saving installation space and improving circuit performance.

[0045] As shown in Figure 2, the aerosol generating device also includes a probe holder 5, which is disposed on the PCB board 2, and the conductive component 4 is fixedly disposed on the probe holder 5. The probe holder 5 enhances the stability of the conductive component 4 on the PCB board 2, preventing bending and deformation of the conductive component 4 after contacting the inner wall of the metal casing 1. Simultaneously, the USB socket 3 has a clearance portion 31, within which the probe holder 5 is located. By providing the clearance portion 31 on the USB socket 3 to allow the probe holder 5 to pass, the probe holder 5 can be prevented from occupying space for other components on the PCB board 2, thus facilitating the miniaturization design of the product.

[0046] As shown in Figures 1 to 4, the inner wall of the metal casing 1 is laser-etched to form a laser-etched area 14. The conductive component 4 abuts against the inner wall of the laser-etched area 14. By forming the laser-etched area 14, the oxide layer on the inner wall of the metal casing 1 can be removed, thereby improving the electrostatic conductivity of the conductive component 4 to the metal casing 1. Optionally, the inner wall of the laser-etched area 14 is arc-shaped, so that the conductive component 4 can fully contact the inner wall of the laser-etched area 14, further improving the electrostatic conductivity of the conductive component 4 to the metal casing 1.

[0047] Furthermore, the metal casing 1 has a first end 11 and a second end 12 arranged opposite to each other. The first end 11 has a mounting port 13, through which the PCB board 2 can be inserted into the metal casing 1. The conductive component 4 abuts against the inner wall of the second end 12, thereby realizing the assembly of the PCB board 2, the USB socket 3, and the conductive component 4 inside the metal casing 1. At the same time, the conductive component 4 extends along the insertion direction of the PCB board 2, so when the PCB board 2 is inserted into the metal casing 1 along the insertion direction, there is no need to consider the pre-pressure generated between the conductive component 4 and the metal casing 1 during the movement, which would affect the assembly. This avoids wear of the conductive component 4 due to pre-pressure during the movement, and also facilitates the assembly of other components on the metal casing 1, thus contributing to the miniaturization design of the product.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
