[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0031] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms “mounting”, “connection”, “connecting” should be understood in a broad sense, for example, can be fixedly connected, or detachably connected, or integrally connected; can be mechanically connected, or electrically connected; can be directly connected, or indirectly connected through an intermediate medium, or the internal communication of two elements. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0032] In the description of this specification, references to terms such as "embodiment," "specific embodiment," and "example" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0033] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of an electronic cigarette 1000 provided in an embodiment of this application. Figure 2 yes Figure 1 The diagram shows an exploded view of the structure of the electronic cigarette 1000.

[0034] For ease of description, the length direction of the electronic cigarette 1000 is defined as the X-axis direction, the width direction of the electronic cigarette 1000 is defined as the Y-axis direction, and the height direction of the electronic cigarette 1000 is defined as the Z-axis direction. The X-axis direction, Y-axis direction, and Z-axis direction are all perpendicular to each other.

[0035] In this embodiment, the electronic cigarette 1000 includes a housing 100, a heating module 200, a heat-conducting support assembly 300, a main board 400, a battery module 500, and a heat-conducting layer 600. The housing 100 has a receiving cavity 101 and a placement hole (not shown), the placement hole communicating with the receiving cavity 101. Inhalable materials such as cigarettes can be placed into or removed from the receiving cavity 101 through the placement hole. The heating module 200, the heat-conducting support assembly 300, the main board 400, the battery module 500, and the heat-conducting layer 600 are all installed in the receiving cavity 101. The heating module 200 has a heating surface 201, which can heat the aerosol-generating material located in the receiving cavity 101, causing at least one volatile component in the aerosol-generating material to evaporate and form an inhalable aerosol.

[0036] In this embodiment, the housing 100 is generally rectangular, with its length greater than its width and height. The housing 100 includes a front housing 110 and a rear housing 120, with the front housing 110 detachably mounted on the rear housing 120 to facilitate maintenance or replacement of the internal functional components of the electronic cigarette 1000. Along the Z-axis, the front housing 110 and the rear housing 120 are abutted against each other, forming a receiving cavity 101.

[0037] The front shell 110 and the rear shell 120 can be made of polycarbonate (PC), which not only ensures that the shell 100 has good strength, high impact strength and fatigue resistance, but also reduces the manufacturing cost of the shell 100. In some other embodiments, the front shell 110 and the rear shell 120 can also be made of metal materials such as aluminum alloy to ensure the machinability and good heat dissipation performance of the shell 100.

[0038] Please refer to the following: Figure 3 and Figure 4 , Figure 3 yes Figure 1 The diagram shows the structure of the heat-conducting support assembly 300 in the electronic cigarette 1000. Figure 4 yes Figure 3 The exploded view of the thermally conductive support assembly 300 shown.

[0039] The heat-conducting bracket assembly 300, the heating module 200, and the heat-conducting layer are installed inside the rear shell 120. It is understood that the inner side of the rear shell 120 is part of the space of the aforementioned receiving cavity 101, and the following description of the inner side of the rear shell 120 can be understood in the same way. The heat-conducting bracket assembly 300 is generally rectangular. The heat-conducting bracket assembly 300 has a plane of symmetry P, and the heat-conducting bracket assembly 300 is mirror-symmetrical about the plane of symmetry P. In this embodiment, the heat-conducting bracket assembly 300 includes a heat-conducting bracket 310 and a heat-conducting element 320. The heat-conducting bracket 310 is provided with a heat-conducting groove 1, the opening of which is located on the top surface of the heat-conducting bracket 310, and the heat-conducting groove 1 is recessed from the top surface of the heat-conducting bracket 310 towards the bottom surface. The heat-conducting element 320 is embedded in the heat-conducting bracket 310.

[0040] It should be noted that the directional terms such as "top" and "bottom" used in the description of the electronic cigarette 1000 in this application are mainly based on the electronic cigarette 1000 in the attached document. Figure 1 The orientation of the display is described, with the positive direction of the Z-axis as "top" and the negative direction of the Z-axis as "bottom". This does not limit the orientation of the electronic cigarette 1000 in actual application scenarios.

[0041] The heat-conducting bracket 310 is made of plastic materials such as polycarbonate, while the heat-conducting component 320 is made of metal. The heat-conducting bracket assembly 300 can be formed through insert molding, meaning the heat-conducting bracket 310 and the heat-conducting component 320 can be an integrated structure formed by insert molding. For example, the heat-conducting component 320 is inserted into a pre-designed mold cavity, molten plastic material is injected into the mold cavity, and after cooling, the heat-conducting bracket assembly 300 is formed.

[0042] It should be noted that in some other embodiments, the heat-conducting element 320 may also be made of other materials with better thermal conductivity, or the heat-conducting bracket 310 and the heat-conducting element 320 may be integrally formed by an assembly process. For example, the heat-conducting bracket 310 and the heat-conducting element 320 may also be assembled into an integral structure by means such as bonding or welding.

[0043] The heat-conducting bracket 310 includes a bottom wall 311, a first side wall 313a, a second side wall 313b, a third side wall 314a, and a fourth side wall 314b. The first side wall 313a and the second side wall 313b are arranged opposite to each other. Along the Y-axis, the first side wall 313a and the second side wall 313b are parallel and spaced apart. The first side wall 313a and the second side wall 313b are mirror-symmetrical about the plane of symmetry P. The bottom wall 311 connects the first side wall 313a and the second side wall 313b and is located on the bottom side of the first side wall 313a and the second side wall 313b.

[0044] The third sidewall 314a and the fourth sidewall 314b are arranged opposite each other, parallel and spaced apart along the X-axis. The third sidewall 314a and the fourth sidewall 314b are connected between the first sidewall 313a and the second sidewall 313b, and are also connected to the bottom wall 311. The third sidewall 314a and the fourth sidewall 314b are located on opposite sides of the bottom wall 311. The first sidewall 313a, the second sidewall 313b, the bottom wall 311, the third sidewall 314a, and the fourth sidewall 314b together form a heat-conducting groove 1. Furthermore, the first sidewall 313a, the second sidewall 313b, the bottom wall 311, the third sidewall 314a, and the fourth sidewall 314b can be integrally formed to increase the overall strength of the heat-conducting support 310.

[0045] In this embodiment, the heat-conducting bracket 310 further includes support members 312, which are used to support and fix the heating module 200. There are four support members 312, namely a first support member 312a, a second support member 312b, a third support member 312c, and a fourth support member 312d. The first support member 312a, the second support member 312b, the third support member 312c, and the fourth support member 312d are all located inside the heat-conducting bracket 310. Specifically, the first support member 312a and the second support member 312b are both fixedly connected to the first side wall 313a and the bottom wall 311. Along the X-axis direction, the first support member 312a and the second support member 312b are spaced apart and parallel. The third support member 312c and the fourth support member 312d are both fixedly connected to the second side wall 313b and the bottom wall 311. Along the X-axis direction, the third support member 312c and the fourth support member 312d are spaced apart and parallel. The third support member 312c is spaced apart from and opposite to the first support member 312a, and is mirror-symmetrical about the plane of symmetry P. The fourth support member 312d is spaced apart from and opposite to the second support member 312b, and is mirror-symmetrical about the plane of symmetry P.

[0046] It should be noted that the directional terms such as "inner" and "outer" used in the description of the electronic cigarette 1000 in this application embodiment are mainly distinguished based on the inside and outside of the housing 100. "Inner" refers to the inside of the housing 100 and "outer" refers to the outside of the housing 100. This does not constitute a limitation on the orientation of the electronic cigarette 1000 in actual application scenarios.

[0047] It should be understood that the four support members 312 not only serve as reinforcing ribs, but also improve the strength and rigidity of the heat-conducting bracket 310 without increasing its thickness, thus preventing deformation of the heat-conducting bracket 310. They also improve the flow of plastic during injection molding, ensuring the precision of the injection molding of the heat-conducting bracket 310.

[0048] Please refer to the following: Figure 5 , Figure 5 yes Figure 3 The top view of the heat-conducting support assembly 300 is shown.

[0049] In this embodiment, the first support member 312a, the second support member 312b, the third support member 312c, and the fourth support member 312d are independent of each other, and gaps 2 exist between the first support member 312a and the third support member 312c, as well as between the second support member 312b and the fourth support member 312d. In some other embodiments, gaps 2 may not exist, the first support member 312a and the third support member 312c may be connected to each other, the second support member 312b and the fourth support member 312d may also be connected to each other, or there may be one, two, or three support members 312, etc. This application does not specifically limit the number of support members 312, as long as the support members 312 are fixedly connected to the inside of the heat-conducting groove 1 and can provide support and fixation for the heating module 200.

[0050] Please see Figure 4 In this embodiment, there are two heat-conducting elements 320, namely a first heat-conducting element 320a and a second heat-conducting element 320b. The first heat-conducting element 320a is embedded in the first sidewall 313a, and the second heat-conducting element 320b is embedded in the second sidewall 313b. In some other embodiments, there may be one or more heat-conducting elements 320, as long as one heat-conducting element is embedded in the first sidewall 313a or the second sidewall 313b.

[0051] The heat-conducting component 320 is a stamped part obtained through a stamping process. During the manufacturing process of the heat-conducting component 320, a press and a die apply external force to the raw material, causing plastic deformation or separation. When the heat-conducting component 320 is made of metals with high thermal conductivity such as aluminum, copper, or silver, these materials are prone to deformation. Therefore, the stamping accuracy of the heat-conducting component 320 needs to be controlled to avoid erroneous deformation, ultimately obtaining the heat-conducting component 320 with the required shape and size. It should be noted that the heat-conducting component 320 can be made of metals other than aluminum, copper, and silver; this application does not specify specific requirements for the material of the heat-conducting component 320.

[0052] In this embodiment, the first heat-conducting element 320a and the second heat-conducting element 320b have the same structure. Next, taking the first heat-conducting element 320a as an example, the structure of the two heat-conducting elements 320 will be described in detail.

[0053] The first heat-conducting element 320a is wavy and extends along the X-axis. The first heat-conducting element 320a includes an inner heat-conducting portion 3, an outer heat-conducting portion 4, and a connecting heat-conducting portion 9. The inner heat-conducting portion 3 is located on the side of the outer heat-conducting portion 4 near the center of the heat-conducting support assembly 300. The connecting heat-conducting portion 9 connects the inner heat-conducting portion 3 and the outer heat-conducting portion 4 to achieve connection between them. The inner heat-conducting portion 3, the outer heat-conducting portion 4, and the connecting heat-conducting portion 9 are integrally formed. In some other embodiments, the first heat-conducting element 320a may also be serrated.

[0054] In this embodiment, the first heat-conducting element 320a includes four inner heat-conducting parts 3, five outer heat-conducting parts 4, and eight connecting heat-conducting parts 9. Along the X-axis, the five outer heat-conducting parts 4 are evenly spaced. Each inner heat-conducting part 3 is connected between two adjacent outer heat-conducting parts 4, and each connecting heat-conducting part 9 is connected between an adjacent inner heat-conducting part 3 and an adjacent outer heat-conducting part 4. It should be noted that there can be one or more inner heat-conducting parts 3, and / or one or more outer heat-conducting parts 4. This application does not specifically limit the number of inner heat-conducting parts 3 and outer heat-conducting parts 4.

[0055] Please see Figures 6 to 9 . Figure 6 yes Figure 3 The left view of the heat-conducting support assembly 300 shown. Figure 7 yes Figure 6 The diagram shows a cross-sectional view of the heat-conducting support assembly 300 taken along the AA direction. Figure 8 yes Figure 5 The diagram shows a cross-sectional view of the heat-conducting support assembly 300 taken along the BB direction. Figure 9 yes Figure 5 The diagram shows a cross-sectional view of the heat-conducting support assembly 300 along the CC direction.

[0056] Four inner heat-conducting parts 3 are exposed relative to the inner surface 7 of the first sidewall 313a (i.e., the groove wall surface of the heat-conducting groove 1), and five outer heat-conducting parts 4 are exposed relative to the outer surface 8 of the first sidewall 313a (i.e., the outer surface of the heat-conducting bracket 310). In this embodiment, the first heat-conducting element 320a includes an inner heat-conducting surface 5 and an outer heat-conducting surface 6 arranged opposite to each other. The inner heat-conducting surface 5 is the surface of the first heat-conducting element 320a close to the center of the heat-conducting bracket assembly 300, and the outer heat-conducting surface 6 is the surface of the first heat-conducting element 320a away from the center of the heat-conducting bracket assembly 300. Specifically, the inner heat-conducting surface 5 includes the inner surfaces of the four inner heat-conducting parts 3, which are exposed relative to the inner surface 7 of the first sidewall 313a. The outer heat-conducting surface 6 includes the outer surfaces of the five outer heat-conducting parts 4, which are exposed relative to the outer surface 8 of the first sidewall 313a. The inner surface of the inner heat-conducting part 3 is flush with the inner surface 7 of the first sidewall 313a, and the outer surface of the outer heat-conducting part 4 is flush with the outer surface 8 of the first sidewall 313b.

[0057] In some other embodiments, the inner surface of the inner heat-conducting part 3 may protrude or be recessed relative to the inner surface 7 of the first sidewall 313a, or the outer surface of the outer heat-conducting part 4 may protrude or be recessed relative to the outer surface 8 of the first sidewall 313b, as long as it does not affect the normal assembly between the components in the electronic cigarette 1000, and the first heat-conducting part 320a will not be pressed into the mold, and will not affect the injection molding process effect.

[0058] In this embodiment, the second heat-conducting element 320b has a structure largely the same as the first heat-conducting element 320a. The second heat-conducting element 320b also includes four inner heat-conducting parts 3, five outer heat-conducting parts 4, and eight connecting heat-conducting parts 9. Specifically, the inner surfaces of the four inner heat-conducting parts 3 are exposed relative to the inner surface of the second sidewall 313b (i.e., the groove wall surface of the heat-conducting groove 1), and the outer surfaces of the five outer heat-conducting parts 4 are exposed relative to the outer surface of the second sidewall 313b (i.e., the outer surface of the heat-conducting support 310). The inner surfaces of the four inner heat-conducting parts 3 are flush with the inner surface of the second sidewall 313b, and the outer surfaces of the five outer heat-conducting parts 4 are flush with the outer surface of the second sidewall 313b. It should be noted that other structures of the second heat-conducting element 320b can be referred to the relevant description of the first heat-conducting element 320a described above, and will not be repeated here.

[0059] In the thermally conductive bracket assembly 300 shown in this embodiment, the thermally conductive bracket 310 and the two thermally conductive components 320 are integrally formed, increasing the overall strength of the thermally conductive bracket assembly 300. This allows the thermally conductive bracket assembly 300 to provide good support and heat conduction, while also reducing cost. Furthermore, the fabrication process of the thermally conductive bracket assembly 300 not only facilitates control of fabrication precision but also allows for the design of positioning or fixing structures to obtain complex structures, making the structure of the thermally conductive bracket assembly 300 more precise and fully meeting the structural design requirements of the product. In addition, it avoids the presence of a large-volume metal bracket inside the electronic cigarette 1000, which helps reduce the risk of a large-volume metal bracket affecting the overall hardware functionality of the device.

[0060] Please see Figure 2 , Figure 4 and Figure 10 , Figure 10 yes Figure 1 The diagram shows a cross-sectional view of the electronic cigarette 1000 cut along the DD direction.

[0061] The heating module 200 is installed inside the rear shell 120. In this embodiment, the heating module 200 is installed on the heat-conducting bracket assembly 300. Specifically, the heating module 200 is installed in the heat-conducting groove 1. The heating module 200 is fixedly assembled to four support members 312. The heating module 200 is partially housed in the heat-conducting groove 1 of the heat-conducting bracket assembly 300, and partially protrudes relative to the heat-conducting groove 1. At this time, one end of the aerosol generating material can be inserted into the heating module 200, that is, the heating module 200 can heat the aerosol generating material to realize the heating function of the electronic cigarette 1000 on the aerosol generating material.

[0062] Furthermore, along the X-axis, the length of the heating module 200 is smaller than the length of the heat-conducting groove 1. Along the X-axis, gaps exist between the two ends of the heating module 200 and the third sidewall 314a and the fourth sidewall 314b, respectively. It should be noted that this application does not specifically limit the dimensions of the heating module 200 and the heat-conducting groove 1, as long as the heating module 200 can be assembled with the heat-conducting support assembly 300.

[0063] Furthermore, each support member 312 is provided with a snap-fit ​​structure (not shown in the figure), so that the heating module 200 can be assembled to the four support members 312 through the snap-fit ​​structure, thereby realizing the support and fixation of the heating module 200 by the four support members 312. In this embodiment, the heating module 200 is cylindrical, and the support surfaces of the four support members 312 that contact the heating module 200 are all arc surfaces adapted to the heating module 200. In some other embodiments, the support surfaces of the four support members 312 can also be planes. This application does not specifically limit the support surfaces of the support members 312, as long as the support members 312 can play a supporting and fixing role for the heating module 200.

[0064] When the electronic cigarette 1000 is working, the heating module 200 heats the aerosol generating material. The heat generated by the heating module 200 during operation is transferred through the inner surfaces of the inner heat-conducting parts 3 in the first heat-conducting element 320a and the second heat-conducting element 320b to the connecting heat-conducting part 9, then through the connecting heat-conducting part 9 to the outer heat-conducting part 4, and finally through the outer surface of the outer heat-conducting part 4 to the outside of the heat-conducting support assembly 300. This allows the heat generated by the heating module 200 during operation to be transferred from the inside to the outside of the heat-conducting support assembly 300. It can be understood that, since the four inner heat-conducting parts 3 and the five outer heat-conducting parts 4 are evenly spaced along the X-axis, the heat generated by the heating module 200 during operation can be evenly transferred from the inside to the outside of the heat-conducting support assembly 300.

[0065] Both the motherboard 400 and the battery module 500 are installed inside the rear cover 120. In this embodiment, both the motherboard 400 and the battery module 500 are installed on the side of the heat-conducting bracket assembly 300 opposite to the heating module 200, with the motherboard 400 located between the heat-conducting bracket assembly 300 and the battery module 500. Specifically, the motherboard 400 is fixedly connected to the bottom surface of the heat-conducting bracket assembly 300. The motherboard 400 can be a circuit board. Various electronic components of the electronic cigarette 1000 can be installed on the motherboard 400, and the motherboard 400 can transmit various electrical signals from the electronic cigarette 1000, thereby controlling the on / off operation of the electronic cigarette 1000. The battery module 500 can be an energy storage device such as a lithium battery or a solar cell, providing power to the various electronic components of the electronic cigarette 1000.

[0066] A thermally conductive layer 600 is installed on the inner side of the rear housing 120. In this embodiment, the thermally conductive layer 600 covers the battery module 500, the motherboard 400, and the thermally conductive bracket assembly 300, and covers the inner surface of the rear housing 120. The thermally conductive layer 600 includes a thermally conductive surface 601 and a heat-dissipating surface 602 disposed opposite to each other. The thermally conductive surface 601 is thermally connected to the heating module 200, and the heat-dissipating surface 602 is the surface of the thermally conductive layer 600 facing the housing 100. The heat-dissipating surface 602 is attached to the cavity wall of the receiving cavity 101. The area of ​​the heat-dissipating surface 602 is larger than the area of ​​the heating surface 201, so as to uniformly transfer the heat generated by the heating film assembly 200 during operation to the housing 100 and avoid the appearance of local hot spots on the housing 100.

[0067] Specifically, the thermally conductive surface 601 is attached to the outer surface of the battery module 500 and the outer surface of the thermally conductive bracket assembly 300, while the heat dissipation surface 602 covers the inner surface of the rear shell 120. The thermally conductive surface 601 of the thermally conductive layer 600 is attached to the outer surface of the outer thermally conductive portion 4 in the first thermally conductive element 320a, thereby achieving a thermally conductive connection between the thermally conductive layer 600 and the heating module 200 through the first thermally conductive element 320a, and further achieving indirect heat conduction between the thermally conductive layer 600 and the heating module 200 through the first thermally conductive element 320a. Furthermore, the thermally conductive surface 601 of the thermally conductive layer 600 is also attached to the outer surface of the outer thermally conductive portion 4 in the second thermally conductive element 320a. For example, the thermally conductive layer 600 may include one or more graphite sheets made of graphite material. In some other embodiments, the heat-conducting surface 601 of the heat-conducting layer 600 can also be in direct contact with the heating module 200 to achieve a heat-conducting connection, thereby realizing direct heat conduction between the heat-conducting layer 600 and the heating module 200.

[0068] The heat-conducting layer 600 has good thermal conductivity and ultra-high heat dissipation efficiency. It can quickly conduct heat from the heat-conducting component 320, distributing it evenly throughout the entire layer, and then uniformly transferring the heat to the rear shell 120. Therefore, when heat is transferred to the rear shell 120, the temperature distribution is uniform, preventing localized overheating. This avoids localized overheating of the electronic cigarette 1000's shell 100, preventing burns to the user, preventing fires, and ensuring user safety.

[0069] When the electronic cigarette 1000 provided in this embodiment is working, the heating module 200 generates heat. The inner heat-conducting part 3 in the first heat-conducting part 320a and the second heat-conducting part 320b can evenly transfer the heat from the heating module 200 to the outer heat-conducting part 4 via the connecting heat-conducting part 9, and then conduct it to the heat-conducting layer 600 via the outer heat-conducting part 4. After the heat is evenly distributed on the heat-conducting layer 600, it is then evenly conducted to the shell 100 via the heat-conducting layer 600, thereby achieving the effect of evenly transferring the heat inside the electronic cigarette 1000 to the outside, achieving the effect of heat conduction and heat dissipation from the inside to the outside.

[0070] Moreover, after the e-cigarette 1000 has been working for a long time, the temperature distribution of the back shell 120 is uniform, which can achieve uniform heat dissipation of the e-cigarette 1000 as a whole. This avoids the situation of local overheating of the e-cigarette 1000, eliminates the "hot spot" area generated during the use of traditional e-cigarettes, thereby avoiding burns to users, preventing fires, ensuring user safety, and improving the user experience.
