[0002] In the conventional electronic atomization device, a heating element is disposed in the housing, and the heating element generates an aerosol by heating the atomization medium, so that the heat of the heating element is transferred to the outside of the housing. In the conventional electronic atomization device, a heat insulating structure is generally provided in the housing, so that the size of the housing needs to be increased to accommodate the installation of the heat insulating structure, which is disadvantageous to the miniaturization of the electronic atomization device. Summary of the Invention [Problem to be solved by the invention]

[0003] In view of this, it is necessary to provide an electronic atomization device that has an improved heat insulating effect and is advantageous for miniaturization in order to solve the above problems. [Means for solving the problem]

[0004] An electronic atomization device includes a housing body having an internal mounting cavity, and an atomization assembly disposed in the mounting cavity, the internal wall of the mounting cavity is provided with a groove, which is an annular groove along the internal wall of the mounting cavity, and there is a radial gap between an outer surface of the atomization assembly and the internal wall of the groove.

[0005] In one embodiment, the atomizing assembly is elastically deformable in the radial direction.

[0006] In one embodiment, the difference between the radial dimension of the atomizing assembly and the radial dimension of the mounting cavity is 0-0.6 mm, and the radial depth of the groove is 0.2-0.4 mm.

[0007] In one embodiment, the atomization assembly includes a heating element and an insulating unit covering the outside of the heating element, a gap exists between the outer surface of the insulating unit and the inner wall of the groove, and the insulating unit is elastically deformable in the radial direction.

[0008] In one embodiment, the insulation unit includes an insulation layer disposed adjacent to the heating element and a heat equalization layer disposed outside the insulation layer, the insulation layer being elastically deformable in the radial direction.

[0009] In one embodiment, the thermal insulation layer is an aerogel layer and / or the thermal isolating layer is a graphite layer.

[0010] In one embodiment, the axial length of the groove is greater than the axial length of the atomizing assembly.

[0011] In one embodiment, the difference between the axial length of the groove and the axial length of the atomizing assembly is 1mm to 20mm.

[0012] In one embodiment, the connection between the inner wall of the groove and the inner wall of the mounting cavity is made by transitioning through a tapered surface.

This gap forms an air layer, which can effectively reduce the direct transfer of heat from the atomizing assembly to the outer surface of the housing body. In addition, since the air layer is formed by directly providing a groove on the inner wall of the mounting cavity, this realization method forms the air layer by thinning the wall thickness of the housing body, which is advantageous for designing a miniaturized electronic atomizing device without increasing the size of the housing body.

[0019] In order to more clearly understand the above objects, features and advantages of the present invention, the following detailed description of specific embodiments of the present invention will be given with reference to the drawings. In the following description, many specific details will be described in order to fully understand the present invention. However, the present invention can be embodied in many other forms different from the embodiments described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] 1 to 3, the electronic atomization device 10 according to an embodiment of the present invention is for realizing atomization of the atomization medium, and at least has a high heat insulation effect and ensures a good usage experience. In this embodiment, the electronic atomization device 10 is used to atomize the solid atomization medium. In another embodiment, the electronic atomization device 10 may also be used to atomize the liquid atomization medium.

[0021] Specifically, the electronic atomizing device 10 includes a housing body 110 and an atomizing assembly 120. A mounting cavity 111 is formed inside the housing body 110, and the atomizing assembly 120 is disposed in the mounting cavity 111. Here, the inner wall of the mounting cavity 111 is provided with a groove 112, which is an annular groove along the inner wall of the mounting cavity 111, and there is a gap between the outer surface of the atomizing assembly 120 and the inner wall of the groove 112 in the radial direction a.

[0022] The atomizing assembly 120 is disposed in the mounting cavity 111 of the housing body 110, and the inner wall of the mounting cavity 111 is provided with a groove 112, which is an annular groove along the circumferential direction of the inner wall of the mounting cavity 111, so that there is a gap between the outer surface of the atomizing assembly 120 located in the mounting cavity 111 and the inner wall of the groove 112. This gap forms an air layer, which can effectively reduce the direct transfer of heat from the atomizing assembly 120 to the outer surface of the housing body 110. In addition, since the air layer is formed by directly providing the groove 112 on the inner wall of the mounting cavity 111, this realization method forms the air layer by thinning the wall thickness of the housing body 110, which is advantageous for designing the electronic atomizing device 10 to be compact without increasing the size of the housing body 110.

[0023] In one embodiment, the groove 112 is an annular groove along the circumferential direction of the inner wall of the mounting cavity 111, and it is understood that the circumferential direction of the annular groove coincides with the circumferential direction of the inner wall of the mounting cavity 111. In another embodiment, when the depth of the groove 112 is not consistent with the circumferential direction of the inner wall of the mounting cavity 111, the circumferential direction of the annular groove may deviate from the circumferential direction of the inner wall of the mounting cavity 111 to some extent, as long as it satisfies that there is a gap between the outer surface of the atomizing assembly 120 and the inner wall of the groove 112 in the radial direction a.

[0024] 3 to 5, in one embodiment, the atomizing assembly 120 includes a heating element 121 and a heat insulating unit 122 covering the outside of the heating element 121, and there is a gap between the outer surface of the heat insulating unit 122 and the inner wall of the groove 112. By providing the heat insulating unit 122, the heat conduction of the heating element 121 to the housing body 110 can be further reduced, effectively reducing the heat loss of the heating element 121 while lowering the temperature of the housing body 110, improving the usage experience.

[0025] Specifically, an atomization cavity 123 is formed in the heating element 121, and the atomization medium can be placed in the atomization cavity 123 so as to be heated and atomized by the heating element 121. The heat insulating unit 122 covers the outside of the heating element 121. Furthermore, the heating element 121 has a cylindrical structure, and a cylindrical atomization cavity 123 is formed in the heating element 121 having the cylindrical structure.

[0026] In another embodiment, the outer shape of the heating element 121 may be a prismatic structure or other shapes, as long as it can form an atomization cavity 123 to facilitate the atomization of the solid atomization medium.

[0027] In one embodiment, the heat insulating unit 122 includes a heat insulating layer 124 disposed adjacent to the heating element 121, and a heat uniformity layer 125 disposed outside the heat insulating layer 124. By providing the heat insulating layer 124 close to the heating element 121, the heat insulating layer 124 can effectively block the heat dissipation of the heating element 121, and ensure the efficiency of the heating and atomization of the atomization medium by the heating element 121. By providing the heat uniformity layer 125 away from the heating element 121, the heat emitted by the heating element 121 through the heat insulating layer 124 can be uniformly conducted to the heat uniformity layer 125, and the heat uniformity layer 125 can uniformly conduct the heat to the housing body 110 through the air layer between the heating element 121 and the inner wall of the groove 112, thereby avoiding the housing body 110 from being locally heated and affecting the usage experience.

[0028] In the conventional method, if the soaking and insulation treatment is not performed, not only will the heat energy consumption of the heating element 121 be high, but also high temperature concentration points will appear in the housing body 110, causing the local temperature of the housing body 110 to rise, affecting the usage experience. If the housing body 110 is prevented from being locally heated only by providing the soaking layer 125, the heat dissipation of the heating element 121 will be large, and the atomization energy consumption of the heating element 121 will be high.

[0029] In this embodiment, the number of layers of the insulating layer 124 is at least two, and each insulating layer 124 is laminated along the radial direction a. By providing at least two insulating layers 124, the heat dissipation path of the heating element 121 in the radial direction a can be effectively extended, and the insulating effect for the heating element 121 can be improved.

[0030] In one embodiment, the length in the axial direction b of the heat-uniform layer 125 is longer than the length in the axial direction b of the heat insulating layer 124. By increasing the length in the axial direction b of the heat-uniform layer 125, the heat-uniform effect can be better realized, and the local temperature of the housing body 110 can be easily reduced, and the heat-uniform effect of the heat transferred to the housing body 110 can be improved. At the same time, by increasing the length in the axial direction b of the heat-uniform layer 125, the temperature of the atomization cavity 123 can be uniformed to a certain extent, and the heat-uniform effect of the aerosol generated by the atomization cavity 123 can be improved.

[0031] In this embodiment, the insulating layer 124 is an aerogel layer. Aerogel refers to a nanoscale porous solid material in which the liquid phase in the gel is replaced with gas through a certain drying method by the sol-gel method. Aerogel has good heat insulation effect. At the same time, the aerogel layer also has a certain elastic deformation ability. In another embodiment, the insulating layer 124 may be a foam layer, a foam ceramic layer, a glass wool layer, a phenolic resin layer, etc., as long as it can exert an effective insulating effect. Alternatively, the insulating layer 124 may be at least two layers, and different layers may be formed of different materials.

[0032] In one embodiment, the heat-uniform layer 125 is a graphite layer. Graphite can withstand high temperatures, has high thermal conductivity, has good chemical stability at room temperature, and is resistant to corrosion by acids, alkalis, and organic solvents. When used at room temperature, graphite can withstand rapid changes in temperature without being destroyed. The heat-uniformity provided by the graphite layer can effectively improve the heat-uniformity effect and ensure the structural stability of the atomization assembly 120. In another embodiment, the heat-uniform layer 125 can be a steel layer, an aluminum layer, etc.

[0033] 2 and 3, in one embodiment, the atomizing assembly 120 is elastically deformable in the radial direction a. During the installation of the atomizing assembly 120 in the mounting cavity 111, the atomizing assembly 120 needs to be compressed in the radial direction a. If the groove 112 is not provided, after the atomizing assembly 120 is installed in the mounting cavity 111, the inner wall of the mounting cavity 111 and the atomizing assembly 120 will have an interference fit, so that the atomizing assembly 120 is always in a compressed state, which will affect the performance of the atomizing assembly 120. In the present invention, the atomizing assembly 120 is installed in the mounting cavity 111 while being compressed in the radial direction a, and can be expanded when it is positioned at the position of the groove 112.

[0034] In this embodiment, the radial dimension of the atomizing assembly 120 in an uncompressed state is equal to or greater than the radial dimension of the mounting cavity 111. Specifically, the difference between the radial dimension of the atomizing assembly 120 in an uncompressed state and the radial dimension of the mounting cavity 111 is smaller than the radial depth of the groove 112 in the radial direction a. Furthermore, when the atomizing assembly 120 is mounted at a position corresponding to the groove 112, the atomizing assembly 120 is stretched, which helps ensure the performance of the atomizing assembly 120. At the same time, there is still a gap between the outer surface of the stretched atomizing assembly 120 and the inner wall of the groove 112, and this gap can still effectively form an air layer to ensure the heat insulation effect.

[0035] In this embodiment, by making the radial dimension of the atomizing assembly 120 in an uncompressed state larger than the radial dimension of the mounting cavity 111, the mounting stability of the atomizing assembly 120 within the mounting cavity 111 can be ensured, and the atomizing assembly 120 can be prevented from coming off the mounting cavity 111.

[0036] In this embodiment, the difference between the radial dimension of the atomizing assembly 120 and the radial dimension of the mounting cavity 111 is 0 to 0.6 mm, and the depth of the groove 112 in the radial direction a is 0.2 mm to 0.4 mm. Here, the difference between the radial dimension of the atomizing assembly 120 in a state without compressive deformation and the radial dimension of the mounting cavity 111 is 0 to 0.6 mm. Specifically, the depth of the groove 112 in the radial direction a is 0.3 mm.

[0037] The radial dimension of the atomizing assembly 120 in an uncompressed state is equal to or larger than the inner diameter of the mounting cavity 111, and the difference between the outer diameter of the atomizing assembly 120 and the inner diameter of the mounting cavity 111 is 0-0.6 mm, so it can be understood that the difference between the one side of the mounting cavity 111 in an uncompressed state of the atomizing assembly 120 is 0-0.3 mm. Thus, when mounting the atomizing assembly 120 in the mounting cavity 111, the outer surface of the atomizing assembly 120 needs to be contracted inward by 0-0.30 mm, that is, the radius of the atomizing assembly 120 needs to be compressed in the radial direction a by 0-0.30 mm. For example, if the difference between the outer diameter of the atomizing assembly 120 in an uncompressed state and the inner diameter of the mounting cavity 111 is 0.2 mm, and the depth of the groove 112 in the radial direction a is 0.3 mm, the outer wall of the atomizing assembly 120 needs to be contracted inward by 0.1 mm in order to mount it in the mounting cavity 111. After the atomizing assembly 120 is attached to a position corresponding to the groove 112, it expands and recovers, forming a gap of 0.2 mm between the atomizing assembly 120 and the inner wall of the groove 112, and forming an air layer with a thickness of 0.2 mm.

[0038] In this embodiment, the groove 112 is an annular groove that runs along the circumferential direction of the inner wall of the mounting cavity 111, so that the entire circumferential outer surface of the atomizing assembly 120 can stretch and recover, and the usage performance of the atomizing assembly 120 can be further ensured.

[0039] In one embodiment, the insulating unit 122 is elastically deformable in the radial direction a. Without the groove 112, the insulating unit 122 will always be in a compressed state after the insulating unit 122 is installed in the mounting cavity 111, which will affect the insulating performance of the insulating unit 122. The groove 112 allows the insulating unit 122 to expand and recover, and there will still be a gap between the insulating unit 122 and the inner wall of the groove 112 after expansion, which effectively forms an air layer to ensure the insulating effect.

[0040] In addition, the heat insulating layer 124 is elastically deformable in the radial direction a. In this embodiment, the aerogel layer is elastically deformable in the radial direction a. In this embodiment, the heat insulating layer 124 is an aerogel layer, so that the use of the aerogel layer not only provides an effective heat insulating effect, but also easily realizes the elastic deformation of the atomizing assembly 120 in the radial direction a, and the atomizing assembly 120 can be effectively mounted in the mounting cavity 111.

[0041] In this embodiment, the heat spreading layer 125 is a graphite layer and is relatively thin, so that the heat spreading layer 125 has a certain degree of flexibility and can accommodate the elastic deformation of the heat insulating layer 124 in the radial direction a.

[0042] In one embodiment, the heat spreading layer 125 is elastically deformable in the radial direction a. Specifically, the heat spreading layer 125 can be made of a material such as thermally conductive silicon, thermoplastic resin, etc., which not only has a high thermal conductivity effect but also can achieve the purpose of elastic deformation in the radial direction a.

[0043] Also, the thermal isothermal layer 125 may be a unitary, e.g., cylindrical, structure, with the insulating layer 124 located within the thermal isothermal layer 125. Of course, in another embodiment, the thermal isothermal layer 125 may further include at least two thermal isothermal sections, each disposed along the circumferential direction of the insulating layer 124.

[0044] In another embodiment, the thermal isotropy layer 125 may further include at least two thermal isotropy sections, each of which is arranged along the circumferential direction of the thermal insulation layer 124, and may have a movable gap between at least two adjacent thermal isotropy sections. In this embodiment, since the thermal insulation layer 124 is elastically deformable in the radial direction a, a movable gap is formed between at least two adjacent thermal isotropy sections when the thermal insulation unit 122 is not compressed, in order to facilitate the thermal insulation unit 122 as a whole to be elastically deformable in the radial direction a. When the thermal insulation unit 122 is compressed in the radial direction, the movable gap gradually decreases and even disappears, thereby achieving the purpose of reducing the radial dimension of the thermal insulation unit 122 in the compressed state, and the thermal insulation unit 122 can be easily installed in the mounting cavity 111. Specifically, the thermal isotropy layer 125 may be a rigid thermal isotropy structure, and the thermal isotropy section may be a rigid structure.

[0045] 2 and 3, in one embodiment, a mounting cavity 111 penetrating the housing body 110 has a mounting hole 113 at one end thereof, and there is a gap between the groove 112 and the mounting hole 113. The atomizing assembly 120 is mounted in the mounting cavity 111 through the mounting hole 113 and positioned at the position of the groove 112. In this embodiment, the atomizing cavity 123 and the mounting hole 113 are in communication with each other, and a solid atomizing medium can be provided in the atomizing cavity 123 through the mounting hole 113.

[0046] In one embodiment, the electronic nebulizer 10 further includes a connection bracket 130 connected to the nebulizer assembly 120 and engaged with the mounting port 113. The provision of the connection bracket 130 further ensures the stability of the mounting of the nebulizer assembly 120 within the mounting cavity 111.

[0047] 3, in one embodiment, the connection portion between the inner wall of the groove 112 and the inner wall of the mounting cavity 111 is connected by transition through a tapered surface. The tapered surface can realize a smooth transition between the inner wall of the groove 112 and the inner wall of the mounting cavity 111, and can prevent the atomizing assembly 120 from hitting a step position in the mounting cavity 111, so as to improve the protection effect for the atomizing assembly 120. In another embodiment, the inner wall of the groove 112 and the inner wall of the mounting cavity 111 can directly transition in a step shape. Alternatively, the inner wall of the groove 112 and the inner wall of the mounting cavity 111 can be connected by transition through a concave arc surface.

[0048] In one embodiment, the length of the axial direction b of the groove 112 is longer than the length of the axial direction b of the atomizing assembly 120. When the atomizing assembly 120 is mounted in the mounting cavity 111 and positioned at the position of the groove 112, the length of the axial direction b of the groove 112 is longer than the length of the axial direction b of the atomizing assembly 120, so that the atomizing assembly 120 can fully expand and recover, and the use efficiency of the atomizing assembly 120 is further ensured.

[0049] In this embodiment, the difference between the length of the groove 112 in the axial direction b and the length of the atomizing assembly 120 in the axial direction b is 1 mm to 20 mm. On the one hand, the difference between the length of the groove 112 in the axial direction b and the length of the atomizing assembly 120 in the axial direction b is too large, and the size of the groove 112 is too long, which causes the thin-walled thick part of the housing body 110 in which the groove 112 is provided to be long, thereby avoiding the impact on the structural stability of the housing body 110. On the other hand, by controlling a certain range of the difference, a sufficient space for the expansion and recovery of the atomizing assembly 120 is ensured. The difference between the length of the groove 112 in the axial direction b and the length of the atomizing assembly 120 in the axial direction b is influenced by the length of the atomizing assembly 120 in the axial direction b, and the longer the length of the atomizing assembly 120 in the axial direction b, the larger the expansion and recovery space required, and the length of the groove 112 in the axial direction b is long in the range of 1 mm to 20 mm.

[0050] 6 to 8, in one embodiment, the housing body 110 has a cylindrical structure, and a mounting cavity 111 is formed within the housing body 110, the shape of the mounting cavity 111 coincides with the outer shape of the housing body 110, and the axial direction of the mounting cavity 111 coincides with the longitudinal direction of the housing body 110.

[0051] In one embodiment, the outer shape of the housing body 110 is a columnar structure, for example a cylindrical structure, and the corresponding cross section of the housing body 110 is circular. In another embodiment, the housing body 110 may be a columnar structure of other shapes, and the corresponding cross section of the housing body 110 may be elliptical, triangular, square, rhombus, trapezoid, pentagonal, hexagonal, octagonal, etc. In this embodiment, the cross section of the housing body 110 is approximately triangular.

[0052] In one embodiment, the housing body 110 may be formed from any suitable material or combination of materials. Examples of suitable materials include metals, alloys, plastics, or composites including one or more of these materials, or thermoplastic materials suitable for food or pharmaceutical applications, such as polypropylene or polyethylene. In certain embodiments, the material forming the housing body 110 is lightweight and not easily broken.

[0053] In another embodiment, the housing body 110 is constructed from a material having a thermal insulating effect, which can further reduce heat transfer to the housing body 110 by the atomizing assembly 120 .

[0054] 1 and 2, in one embodiment, the electronic atomization device 10 further includes a battery assembly 140 disposed on the housing body 110 and electrically connectable to the atomization assembly 120. By providing the battery assembly 140, power can be efficiently supplied to the atomization assembly 120, facilitating the heating and atomization of the atomization assembly 120. Specifically, the battery assembly 140 is electrically connected to the heating element 121.

[0055] In one embodiment, the housing body 110 is provided with an accommodating cavity 114 disposed in the axial direction of the mounting cavity 111 and communicating with the mounting cavity 111, and the battery assembly 140 is disposed in the accommodating cavity 114. The accommodating cavity 114 can effectively provide an installation space for the battery assembly 140. Specifically, the accommodating cavity 114 is located on the side of the mounting cavity 111 farther from the mounting opening 113. In this embodiment, the radial dimension of the accommodating cavity 114 is consistent with the radial dimension of the mounting cavity 111, and the accommodating cavity 114 is coaxial with the mounting cavity 111. Furthermore, a cavity structure having the same radial dimension is formed inside the housing body 110, and the portion for mounting the atomizing assembly 120 is the mounting cavity 111, and the portion for mounting the battery assembly 140 is the accommodating cavity 114, which further reduces the complexity of the structure of the housing body 110.

[0056] In one embodiment, the battery assembly 140 includes a controller 141 and cells 142 electrically connected to the controller 141, and the heating element 121 is electrically connected to the controller 141. The controller 141 can control electrical communication of the cells 142 to the heating element 121.

[0057] Specifically, the controller 141 is located between the atomizing assembly 120 and the cell 142, and a charging connector is formed at the end of the cell 142 far from the controller 141. Charging the cell 142 is facilitated through the charging connector.
