[0025] In one embodiment of this utility model, the aerosol generating device includes:

[0026] The outer casing 100 has a receiving cavity;

[0027] Heat source assembly 200 is disposed inside the receiving cavity; and

[0028] The heat-conducting component 300 includes a heat-conducting sheet 310 and an elastic arm 320. The heat-conducting sheet 310 is attached to the heat source assembly 200. The elastic arm 320 is located on the side of the heat-conducting sheet 310 away from the heat source assembly 200. One end of the elastic arm 320 is connected to the heat-conducting sheet 310, and the other end of the elastic arm 320 is suspended and abuts against the outer shell 100 to transfer the heat of the heat source assembly 200 to the outer shell 100.

[0029] The aerosol generating device of this utility model includes a housing 100, a heat source component 200, and a heat-conducting component 300. The heat-conducting component 300 includes a heat-conducting sheet 310 and an elastic arm 320 connected together. The heat-conducting sheet 310 is attached to the heat source component 200, and the elastic arm 320 abuts against the housing 100. When the aerosol generating device is working, the heat source component 200 generates heat. The heat generated by the heat source component 200 can be conducted to the housing 100 through the heat-conducting sheet 310 and the elastic arm 320 in sequence. The heat is dissipated through the large area of ​​the housing 100, which reduces the heat accumulation in the containment cavity, lowers the temperature of the components in the containment cavity, and helps to reduce the risk of damage to the aerosol generating device and extend its service life. The cantilevered end of the elastic arm 320 abuts against the outer shell 100, allowing the elastic arm 320 to deform to a certain extent when it abuts against the outer shell 100. On the one hand, the elastic force generated by the deformation of the elastic arm 320 improves the tightness of the contact between the heat-conducting component 300 and the outer shell 100, avoiding gaps between the heat-conducting component 300 and the outer shell 100 and ensuring the effectiveness of the heat transfer path. On the other hand, it reduces the number of assembly dimensions that need to be controlled, reducing the processing and assembly difficulty. Furthermore, the heat-conducting component 300 is better able to adapt to dimensional changes caused by thermal expansion and contraction, avoiding damage or poor contact between the heat-conducting component 300 and the outer shell 100 due to thermal stress, thus improving the reliability of the aerosol generation device.

[0030] In one embodiment, the end of the elastic arm 320 near the heat-conducting sheet 310 is bent and connected to the heat-conducting sheet 310.

[0031] Reference Figure 1 and Figure 2 In the embodiments of this utility model, the heat-conducting sheet 310 and the elastic arm 320 are integrally formed and manufactured by bending process, which ensures the reliability of the connection between the heat-conducting sheet 310 and the elastic arm 320 and the consistency of the heat conduction performance, thereby improving the heat conduction effect of the heat-conducting component 300. In addition, it reduces the manufacturing difficulty of the heat-conducting component 300 and reduces the number of parts that need to be assembled, making assembly simpler and more convenient.

[0032] In one embodiment, the elastic arm 320 includes:

[0033] Support segment 321, one end of which is bent and connected to the heat-conducting sheet 310, and the other end of which extends away from the heat source assembly 200; and

[0034] The elastic segment 322 has one end bent and connected to the end of the support segment 321 away from the heat-conducting sheet 310, and the other end of the elastic segment 322 extends obliquely toward the outer shell 100 so as to abut against the outer shell 100.

[0035] Reference Figure 1 and Figure 2 In an embodiment of this utility model, the elastic arm 320 includes a support section 321 and an elastic section 322. The support section 321 connects the heat-conducting plate 310 and the elastic section 322. The end of the elastic section 322 away from the support section 321 abuts against the outer shell 100. The support section 321 increases the gap between the elastic section 322 and the heat-conducting plate 310, so that the heat-conducting plate 310, the support section 321, and the elastic section 322 form a shape as shown in the figure. Figure 1 The U-shaped structure shown improves the elastic performance of the elastic segment 322 and is simple in structure and easy to process. Specifically, in this embodiment, the support segment 321 is perpendicular to the heat-conducting plate 310.

[0036] In one embodiment, the elastic arm 320 further includes a scratch-resistant section 323, one end of which is bent and connected to one end of the elastic section 322 that abuts against the outer casing 100, and the other end of which extends toward the heat-conducting sheet 310.

[0037] Reference Figure 1 and Figure 2 In an embodiment of this utility model, the elastic arm 320 further includes a scratch-resistant section 323. The end of the elastic arm 320 near the outer shell 100 is bent toward the heat-conducting plate 310 to form the scratch-resistant section 323, so that the bend where the scratch-resistant section 323 and the elastic section 322 are connected abuts against the outer shell 100. That is, the side wall of the elastic arm 320 facing the inner wall of the receiving cavity abuts against the outer shell 100, rather than the end of the elastic arm 320 abutting against the outer shell 100, thus avoiding the elastic arm 320 scratching the outer shell 100 and extending the service life of the outer shell 100.

[0038] In one embodiment, at least two elastic arms 320 are provided at intervals along the length of the heat-conducting sheet 310; and / or,

[0039] The heat-conducting component 300 is made of phosphor bronze.

[0040] Reference Figure 2In this embodiment of the present invention, at least two elastic arms 320 are provided along the length of the heat-conducting sheet 310. By increasing the number of elastic arms 320, the heat from the heat source assembly 200 can be conducted to different parts of the outer shell 100 through the heat-conducting element 300, thereby improving the uniformity of heat dissipation of the outer shell 100, dissipating more heat in the same amount of time, improving the heat dissipation performance of the aerosol generating device, and avoiding heat concentration in a certain area, reducing thermal damage to the outer shell 100, and making the heat distribution on the outer shell 100 more uniform. In addition, under the combined action of the elasticity of multiple elastic arms 320, the positive pressure between the outer shell 100 and the heat-conducting element 300 is increased, making it less likely for the heat-conducting element 300 to slide relative to the outer shell 100, and improving the reliability of the heat-conducting element 300 in the receiving cavity.

[0041] In this embodiment of the invention, the heat-conducting element 300 is made of phosphor bronze. Phosphor bronze has good thermal conductivity, enabling it to quickly conduct the heat generated by the heat source component 200 to the heat-conducting plate 310, and then quickly transfer it to the outer shell 100 through the elastic arm 320, thereby improving heat transfer efficiency. Furthermore, phosphor bronze has good elasticity and fatigue resistance, allowing the elastic arm 320 to maintain good contact pressure with the outer shell 100, thus giving the heat-conducting element 300 a longer service life.

[0042] In one embodiment, the heat-conducting component 300 further includes a connecting portion 330, which is disposed on the heat-conducting sheet 310, and the heat-conducting sheet 310 is detachably connected to the heat source assembly 200 through the connecting portion 330.

[0043] Reference Figures 1 to 3 In an embodiment of this utility model, the heat-conducting component 300 further includes a connecting portion 330, which can be detachably connected to the heat source component 200 by means of snap-fit, threaded connection, etc. On the one hand, this allows the heat-conducting sheet 310 to be easily removed from the heat source component 200 for cleaning, maintenance or replacement, thereby extending the service life of the aerosol generating device and ensuring heat transfer efficiency; on the other hand, it improves the compatibility of the heat-conducting component 300, making it applicable to heat source components 200 of different types or specifications.

[0044] In one embodiment, one end of the connecting portion 330 is bent and connected to the heat-conducting plate 310, and the other end of the connecting portion 330 extends in a direction away from the elastic arm 320 and is engaged with the heat source assembly 200.

[0045] In this embodiment of the invention, the connecting part 330 is connected to the heat source assembly 200 by a snap-fit ​​connection, which is simple in structure and easy to assemble and disassemble. Specifically, in this embodiment, the entire heat-conducting component 300 is formed by cutting and bending a piece of sheet metal, that is, both the elastic arm 320 and the connecting part 330 are formed by bending, which ensures the connection strength between the various parts of the heat-conducting component 300 and reduces the processing difficulty of the heat-conducting component 300.

[0046] In one embodiment, the aerosol generating device further includes a snap-fit ​​structure, which includes a snap-fit ​​interface 331 and a snap-fit ​​protrusion 211. One of the connecting portion 330 and the heat source assembly 200 is provided with the snap-fit ​​interface 331, and the other of the connecting portion 330 and the heat source assembly 200 is provided with the snap-fit ​​protrusion 211 corresponding to the snap-fit ​​interface 331. The snap-fit ​​interface 331 and the snap-fit ​​protrusion 211 cooperate to snap the connecting portion 330 into the heat source assembly 200.

[0047] Reference Figures 1 to 3 In the embodiments of this utility model, the connecting part 330 and the heat source component 200 are connected by a snap-fit ​​structure. The snap-fit ​​structure includes a snap-fit ​​interface 331 and a snap-fit ​​protrusion 211 corresponding to each other. The structure is simple and easy to implement. The snap-fit ​​interface 331 can be provided on the connecting part 330 and the snap-fit ​​protrusion 211 can be provided on the heat source component 200; or the snap-fit ​​interface 331 can be provided on the heat source component 200 and the snap-fit ​​protrusion 211 can be provided on the connecting part 330.

[0048] Specifically, in this embodiment, refer to Figure 3 A snap-fit ​​interface 331 is provided on the connecting part 330, and a snap-fit ​​protrusion 211 is provided on the heating element 210. The width of the snap-fit ​​interface 331 changes from the opening to the bottom with a trend of first decreasing and then increasing. The width of the middle part of the snap-fit ​​interface 331 is slightly smaller than the thickness of the snap-fit ​​protrusion 211. When the snap-fit ​​protrusion 211 is inserted into the snap-fit ​​interface 331, the connecting part 330 at the snap-fit ​​interface 331 undergoes a certain deformation, so that the two inner walls in the middle of the snap-fit ​​interface 331 clamp the two sides of the snap-fit ​​protrusion 211, thereby realizing the snap-fit ​​fixation between the connecting part 330 and the heat source assembly 200.

[0049] In one embodiment, the heat source assembly 200 includes a heating element 210 and a circuit board 220, the circuit board 220 being fixed to one side of the heating element 210, and the heat-conducting sheet 310 being attached to the side of the circuit board 220 opposite to the heating element 210.

[0050] Combination Figure 2 and Figure 3In an embodiment of this utility model, the heat source assembly 200 includes a heating element 210 and a circuit board 220. The circuit board 220 is disposed between the heating element 210 and the heat-conducting sheet 310. The heat-conducting sheet 310 is attached to the circuit board 220. The heat generated by the heating element 210 is conducted to the external environment through the circuit board 220, the heat-conducting element 300, and the outer shell 100 in sequence. The heat transferred to the circuit board 220 and the heat generated by the circuit board 220 itself are conducted to the external environment through the heat-conducting element 300 and the outer shell 100 in sequence. The heat-conducting sheet 310 is attached to the circuit board 220, which reduces the heat accumulation on the circuit board 220 and lowers the temperature of the circuit board 220. This helps to reduce the risk of damage to the circuit board 220 and extend the service life of the circuit board 220.

[0051] A control experiment was conducted at an ambient temperature of 40℃, and the specific experimental data are shown in the table below:

[0052] Temperature at window 210 of heating element (°C) 300 without thermal conductive parts 116.6 300 with thermal conductive components 75.5

[0053] It can be seen that by setting the heat-conducting component 300, the temperature around the heating element 210 is significantly reduced. Similarly, the temperature of the circuit board 220 and other components in the containment cavity will also decrease, thereby reducing the risk of heat damage to each component and extending the service life of the aerosol generating device.

[0054] In one embodiment, an insulating adhesive 230 is provided between the circuit board 220 and the heating element 210, and the circuit board 220 is bonded and fixed to the heating element 210 by the insulating adhesive 230.

[0055] Combination Figure 2 and Figure 3 In this embodiment of the utility model, the circuit board 220 and the heating element 210 are bonded and fixed together by insulating adhesive 230, which ensures the firmness of the circuit board 220 and enables the heat generated by the heating element 210 to be effectively transferred to the circuit board 220, and then transferred to the outer casing 100 through the circuit board 220, ensuring that the heat is dissipated in time.

[0056] In one embodiment, both the heat-conducting element 300 and the outer casing 100 are made of conductive materials.

[0057] In the embodiments of this utility model, the heat-conducting component 300 and the outer shell 100 are both made of conductive materials. For example, the heat-conducting component 300 can be made of copper or copper alloy, and the outer shell 100 can be made of aluminum or aluminum alloy. This allows the circuit board 220, the heat-conducting component 300, and the outer shell 100 to not only form a heat transfer path but also a conductive path, thereby achieving grounding. This improves the safety of the aerosol generating device, ensures user safety, and also enables static electricity discharge, preventing static electricity from damaging the circuit board 220.

[0058] In summary, by incorporating the heat-conducting component 300, the heat transferred from the heating element 210 to the circuit board 220, as well as the heat generated by the circuit board 220 itself, can be transferred to the outer casing 100 through the heat-conducting component 300. The heat is then dissipated to the external environment through the larger area of ​​the outer casing 100, thereby reducing heat accumulation inside the containment cavity and lowering the temperature of the components within the cavity. The heat-conducting component 300 is equipped with an elastic arm 320, which abuts against the outer casing 100, ensuring a tight contact between the heat-conducting component 300 and the outer casing 100. This reduces the requirements for the machining and assembly precision of the heat-conducting component 300 and improves the ease of assembly of the heat-conducting component 300 components. The connecting portion 330 of the heat-conducting component 300 engages with the snap-fit ​​protrusion 211 of the heating element 210 via a snap-fit ​​interface 331, facilitating easy assembly and disassembly. This allows the circuit board 220 to be sandwiched between the heating element 210 and the heat-conducting plate 310, ensuring the effectiveness of the heat transfer path.
