[0022] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] like Figures 1 to 3 As shown, an aerosol generating device provided by one embodiment of the utility model includes a device body 1, in which a heating module 12 for heating an aerosol generating product (not shown) is arranged, and the device body 1 includes a first shell 11, and the first shell 11 has a first heat dissipation area 111 and a second heat dissipation area 112.

[0024] The aerosol generating device further includes a heat sink 3 , the first heat sink region 111 is adjacent to the heating module 12 , and the second heat sink region 112 is adjacent to the heat sink 3 .

[0025] The aerosol generating device also includes a heat conductive member 2, one side of which is in contact with the heating module 12 and the heat sink 3, and the other side of which is adjacent to the first shell 11. Heat can be transferred between the heating module 12 and the heat sink 3 through the heat conductive member 2, and the heat of the heating module 12 and the heat sink 3 can be dissipated to the first shell 11 through the heat conductive member 2.

[0026] During the process of heating the aerosol generating product by the heating module 12 of the aerosol generating device of this embodiment, part of the heat generated on the heating module 12 is transferred to the heat conductive member 2 and directly dissipated by the heat conductive member 2 to the corresponding first heat dissipation area 111 on the first shell 11, and the other part is quickly transferred to the heat sink 3 through the heat conductive member 2. The heat transferred to the heat sink 3 is then transferred to the heat conductive member 2 by the heat sink 3, and then dissipated by the heat conductive member 2 to the corresponding second heat dissipation area 112 on the first shell 11. On the one hand, the heat generated by the heating module 12 will not be concentrated and dissipated to the first heat dissipation area 111 on the first shell 11, thereby avoiding the heating caused by heat concentration. Moreover, since the heat sink 3 shares the heat, the heat dissipated to the first heat dissipation area 111 and the second heat dissipation area 112 is relatively uniform, so that the overall temperature of the first shell 11 is relatively low, thereby avoiding the problem of the user feeling hot when holding the first shell 11 of the aerosol generating device, thereby improving the user experience of the aerosol generating device. On the other hand, the heating module 12 can quickly dissipate heat to the heat sink 3 through the heat conductive element 2 to avoid overheating of the heating module 12, and can also avoid excessive heat dissipation directly through the first shell 11, and slowly dissipate heat through the heat sink 3. The heat sink 3 has a certain heat storage effect, which can improve the heating efficiency of the aerosol generating device.

[0027] Please refer to Figure 2 and Figure 4 In one embodiment, the heat-conducting element 2 includes a heat-conducting body 21, and the heat-conducting body 21 is provided with a first heat-conducting portion 211 and a second heat-conducting portion 212, and the first heat-conducting portion 211 is connected to the second heat-conducting portion 212, and the heat-generating module 12 includes a second shell 121, and the first heat-conducting portion 211 contacts the second shell 121, and the second heat-conducting portion 212 contacts the heat sink 3.

[0028] Specifically, the heat-conducting body 21 of this embodiment can be made of a graphite sheet. It can be understood that the graphite sheet is made of a graphite material, and the graphite sheet has a high thermal conductivity, so that the heat on the heating module 12 can be transferred to the heat sink 3 more quickly, further improving the heat dissipation efficiency of the heat-conducting member 2 and the heat sink 3 to the heating module 12.

[0029] It can be understood that in some embodiments, a heating element 122 for generating heat is provided in the second shell 121 of the heating module 12, and the heating element 122 is used to provide heat for heating the aerosol generating product. During the heating process, the heat diffuses to the second shell 121, and the heat is transferred to the heat sink 3 in sequence by the second shell 121, the first heat conducting part 211, and the second heat conducting part 212.

[0030] In one embodiment, if Figure 4 As shown, combined with Figure 2 The heat conducting component 2 further includes a heat conducting adhesive layer 22 , the heat conducting adhesive layer 22 is filled between the first heat conducting portion 211 and the second shell 121 , and the heat conducting adhesive layer 22 is filled between the second heat conducting portion 212 and the heat dissipating component 3 .

[0031] It can be understood that the thermally conductive adhesive layer 22 is sticky, and the thermally conductive body 21 can contact and adhere to the heating module 12 and the heat sink 3 through the thermally conductive adhesive layer 22, thereby improving the convenience and stability of installation.

[0032] In one embodiment, the thickness of the thermal conductive adhesive layer 22 is 0.01 mm to 0.05 mm (eg, 0.02 mm, 0.03 mm, and 0.04 mm, etc.) Further, the thickness of the thermal conductive adhesive layer 22 is 15% of the thickness of the thermal conductive body 21 .

[0033] In the above embodiment, the heat-conducting body 21 has not only its own thermal resistance but also the thermal resistance brought by the thermal conductive adhesive layer 22. When the area and thickness are constant, the thermal conductivity is inversely proportional to the thermal resistance. The heat-conducting part 2 has the thermal resistance of the heat-conducting body 21 and the thermal resistance of the thermal conductive adhesive layer 22, so the thermal resistance of the heat-conducting part 2 is relatively large, and the thermal conductivity of the heat-conducting part 2 will be reduced conversely. The thickness of the thermal conductive adhesive layer 22 is 0.01 mm to 0.05 mm, and the thickness of the thermal conductive adhesive layer 22 is 15% of the thickness of the heat-conducting body 21, so the thickness of the thermal conductive adhesive layer 22 is very small, the thermal resistance of the heat-conducting body 21 is relatively small, and the thermal conductivity is relatively high. The thermal conductive adhesive layer 22 allows the heat on the heating module 12 to be quickly transferred to the heat-conducting body 21, and the heat-conducting body 21 is quickly transferred to the heat dissipating part 3, further ensuring the heat dissipation efficiency of the heat-conducting part 2 and the heat dissipating part 3 to the heating module 12.

[0034] In one embodiment, the contact area between the first heat conducting part 211 and the second shell 121 accounts for more than 50% of the outer wall area of ​​the second shell. It can be understood that the contact area between the first heat conducting part 211 of the heat conducting member 2 and the second shell 121 of the heating module 12 is relatively large, so that the heat generated by the heating module 12 can be quickly transferred to the heat dissipating member 3 through the heat conducting member 2, further ensuring the heat dissipation efficiency of the aerosol generating device.

[0035] In one embodiment, if Figure 4 As shown, combined with Figure 2 , the heat-conducting member 2 further includes a temperature-averaging layer 23, which is covered on the heat-conducting body 21. The temperature-averaging layer 23 is adjacent to the first shell 11, so that heat can be uniformly radiated to the first shell 11. Specifically, the temperature-averaging layer 23 covers the first heat-conducting part 211 and the second heat-conducting part 212 of the heat-conducting body 21. It can be understood that the thermally conductive adhesive layer 22 is arranged on the inner surface of the heat-conducting body 21, and the temperature-averaging layer 23 is arranged on the outer surface of the heat-conducting body 21, that is, on the side adjacent to the first shell 11. Preferably, the temperature-averaging layer 23 is aerogel, which has the function of temperature-averaging and heat-insulating. In this embodiment, the inner surface of the heat-conducting body 21 is the thermally conductive adhesive layer 22, and the outer surface of the heat-conducting body 21 is the temperature-averaging layer 23. The thermally conductive adhesive layer 22 can make the heat on the heating module 12 quickly transferred to the heat-conducting body 21 through the thermally conductive adhesive layer 22, and the heat-conducting body 21 can quickly transfer the heat to the heat dissipating member 3. On the one hand, the temperature-averaging layer 23 has the function of equalizing temperature, and the heat is evenly dissipated to the first shell 11 through the temperature-averaging layer 23, further avoiding heat concentration on the first shell 11; on the other hand, the temperature-averaging layer 23 also has the function of heat preservation, which slows down the heat dissipation speed to avoid overheating of the first shell 11, and can improve the heating efficiency of the heating module 12.

[0036] In one embodiment, if Figure 3 As shown, the heat sink 3 includes a connecting portion 31 and a main body 32, a first side of the connecting portion 31 abuts against the heating module 12, a second side of the connecting portion 31 is connected to the main body 32, and a radial dimension of the connecting portion 31 is smaller than a radial dimension of the main body 32. When the heat sink 3 is connected to the heating module 12, a part of the heat generated by the heating module 12 is directly transferred to the main body 32 through the connecting portion 31, and another part of the heat is quickly transferred to the main body 32 through the heat conductive member 2. In this embodiment, the heat sink 3 includes a connecting portion 31 and a main body 32, and the space vacated by the connecting portion 31 can be used to accommodate other structures of the aerosol generating device on the one hand, and on the other hand, when the heat of the heating module 12 is lower than that of the heat sink 3, it effectively prevents excessive heat from being transferred to the heating module 12.

[0037] In one embodiment, if Figure 1 and Figure 2As shown, the aerosol generating device includes a device body 1, and the device body 1 includes a first shell 11 and a fixed bracket 13. The fixed bracket 13 is located in the first shell 11, and the heating module 12 and the heat sink 3 are both arranged on the fixed bracket 13. It can be understood that the fixed bracket 13 can play a role in fixing the heating module 12 and the heat sink 3, so that a gap is left between the heat conductor 2 and the first shell. A gap is left between the heat conductor 2 and the inner wall of the first shell 11, and the heat conductor 2 radiates heat to the first shell 11. On the one hand, the gap is used for the air intake of the heating module 12, and the incoming gas can be preheated. On the other hand, it has the function of heat insulation. In other embodiments, the heat conductor 2 and the first shell 11 directly transfer heat by heat conduction.

[0038] The above are merely embodiments of the aerosol generating device of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
