The atomization bracket is clasped on the base, and an atomization cavity is formed between the atomization bracket and the base. The liquid reservoir is sleeved on the base. Since the base has an open structure, the atomized liquid in the atomization cavity or the condensed liquid after atomization will leak out from the base, and then will seep out from an abutment gap between the liquid reservoir and the base. Therefore, in the related art, a sealing ring will be sleeved on an abutment wall between the base and the liquid reservoir to prevent the atomized liquid or the condensed liquid from seeping out, resulting in relatively complicated assembling process, and thus manufacturing cost is relatively high.SUMMARY

[0042] Hereinafter, exemplary embodiments of the present application will be described in detail with reference to the drawings. Apparently, the described embodiments are only some embodiments of the present application, rather than all embodiments of the present application. It should be understood that, the present application is not limited to the exemplary embodiments described herein.

[0043] FIG. 1 is an explode schematic diagram of an atomization device according to an exemplary embodiment of the present application. FIG. 2 is a section view of an atomization device according to an exemplary embodiment of the present application. FIG. 3 is another section view of an atomization device according to an exemplary embodiment of the present application. As shown in FIG. 1 to FIG. 3, an atomization device 200 is provided in an embodiment of the present application. The atomization device 200 may include an atomization assembly 100 and a liquid reservoir 210, and the liquid reservoir 210 may be sleeved on the atomization assembly 100. In practice applications, after the atomized liquid stored in the liquid reservoir 210 enters the atomization assembly 100, the atomization assembly 100 may heat up the atomized liquid to achieve the atomization effect.

[0044] Specifically, FIG. 4 is a schematic structural diagram of a base according to an exemplary embodiment of the present application. As shown in FIG. 1 to FIG. 4, the atomization assembly 100 may include an atomization bracket 110, a base 120 and an atomization core 130. The base 120 is provided with a matching cavity 121. The matching cavity 121 is a cavity chamber having an opening 122 at an end and enclosed on all sides. The atomization bracket 110 enters the matching cavity 121 through the opening 122. The atomization bracket 110 matches with the matching cavity 121. That is, the atomization bracket 110 and the base 120 are engaged with each other. In a case that the atomization bracket 110 matches with the matching cavity 121, a region between the matching cavity 121 and the atomization bracket 110 forms an atomization cavity 123. The atomization core 130 is provided in the atomization cavity 123.

[0045] In practice applications, the liquid reservoir 210 is sleeved on the base 120. The atomized liquid in the liquid reservoir 210 enters the atomization cavity 123 through the atomization bracket 110. The atomization core 130 heats up the atomized liquid in the atomization cavity 123 to achievethe atomization effect. It should be understood that, since the matching cavity 121 of the base 120 is a cavity chamber enclosed on all sides, therefore, a portion of a side wall of the base 120 corresponding to the atomization cavity 123 is also an enclosed structure. In this way, the atomized liquid in the atomization cavity 123 and the condensed liquid formed by condensation will not leak out from the inside of the atomization cavity 123 onto an outer wall of the base 120, and thus will not seep out from an abutment gap between the liquid reservoir 210 and the base 120. Therefore, in the embodiments of the present application, it is not necessary to provide a sealing ring between the liquid reservoir 210 and the base 120, thereby reducing the assembling process of sleeving the sealing ring and also reducing the number of sealing ring required for using, and thus the manufacturing cost is saved.

[0046] In summary, according to the atomization assembly 100 and the atomization device 200 provided by the embodiments of the present application, the base 120 is provided with the matching cavity 121, and the matching cavity 121 is a cavity chamber having an opening 122 at an end and enclosed on all sides. In a first aspect, the atomization bracket 110 cooperates with the matching cavity 121 by the opening 122, such that a region between the matching cavity 121 and the atomization bracket 110 forms the atomization cavity 123. The atomization core 130 heats up the atomized liquid in the atomization cavity 123 to achieve the atomization effect. In a second aspect, since the matching cavity 121 is a cavity chamber enclosed on all sides, the side wall portion of the base 120 corresponding to the atomization cavity 123 is also an enclosed structure. The atomized liquid in the atomization cavity 123 and the condensed liquid formed by condensation will not leak out from the inside of the atomization cavity 123 onto the outer wall of the base 120, and thus will not seep out from the abutment gap between the liquid reservoir 210 and the base 120. Therefore, it is not necessary to provide a sealing ring between the liquid reservoir 210 and the base 120, thereby reducing the assembling process of sleeving the sealing ring and also reducing the number of sealing ring required for using, and thus the manufacturing cost is saved.

[0047] In an embodiment, an outer wall of the base 120 includes an opaque layer. The opaque layer may shield the atomization cavity 123 such that the atomized liquid in the atomization cavity 123 and the condensed liquid are invisible.

[0048] It should be understood that, the opaque layer may be made of an opaque material. In the present application, the specific material of the opaque material is not limited, as long as it can achieve the shielding effect.

[0049] As shown in FIG. 1 to FIG. 3, the atomization assembly 100 may also include a sealing member 140, and the sealing member 140 is sleeved at a top of the atomization bracket 110. Inpractice applications, after the liquid reservoir 210 is sleeved on the base 120, the sealing member 140 is located inside the liquid reservoir 210, and an outer wall of the sealing member 140 abuts against an inner wall of the liquid reservoir 210. In this way, during a process that the atomized liquid in the liquid reservoir 210 passes through the atomization bracket 110, the sealing member 140 prevents the atomized liquid from sliding down along the inner wall of the liquid reservoir 210 to the bottom of the liquid reservoir 210, and thus preventing any atomized liquid from arriving to an abutment position between the liquid reservoir 210 and the base 120.

[0050] FIG. 5 is a schematic structural diagram of a sealing member according to an exemplary embodiment of the present application. FIG. 6 is a schematic structural diagram of an atomization bracket according to an exemplary embodiment of the present application. As shown in FIG. 5 and FIG. 6, the top of the atomization bracket 110 is provided with a limiting groove 111, the sealing member 140 is provided with a limiting portion 141, and the limiting portion 141 matches with the limiting groove 111. In this way, it is convenient for assembling of the sealing member 140 and the atomization bracket 110, and meanwhile, it may also limit the positions of the sealing member 140 and the atomization bracket 110 after assembling, thereby preventing the sealing member 140 from loosening with respect to the atomization bracket 110, and thus ensuring that the sealing member 140 may achieve the sealing effect permanently.

[0051] It should be noted that, a shape of the limiting portion 141 may include a rectangle, a circle, a polygon, or the like. The limiting groove 111 has a shape matches with the shape of the limiting portion 141.

[0052] As shown in FIG. 5, the outer wall of the sealing member 140 is provide with a plurality of ribs 142. In practice applications, after the liquid reservoir 210 is sleeved on the base 120, the plurality of ribs 142 abut against the inner wall of the liquid reservoir 210. In this way, the plurality of ribs 142 may form multi-stage barriers against the atomized liquid in the liquid reservoir 210, thereby further preventing the atomized liquid from flowing along the inner wall of the liquid reservoir 210 to the bottom of the liquid reservoir 210, and thus effectively improving the sealing effect of the sealing member 140.

[0053] In an embodiment, the rib 142 has an annular structure. Thus, it is possible to achieve the sealing effect in different directions.

[0054] As shown in FIG. 1, the outer wall of the base 120 is provided with a first matching portion 230, liquid reservoir 210 is provided with a second matching portion 240, and the first matching portion 230 removably matches with the second matching portion 240. In practice applications, the liquid reservoir 210 is sleeved on the base 120, the first matching portion 230 and the second matching portion 240 match with each other, thereby achieving fast assembling of theliquid reservoir 210 and the base 120. Moreover, since the matching manner between the first matching portion 230 and the second matching portion 240 is the removable manner, it is convenient for fast disassembling of the liquid reservoir 210 and the base 120. That is, through the removable matching manner between the first matching portion 230 and the second matching portion 240, the assembling / disassembling efficiency between the liquid reservoir 210 and the base 120 is effectively improved.

[0055] FIG. 7 is another exploded schematic diagram of an atomization device according to an exemplary embodiment of the present application. FIG. 8 is another section view of an atomization device according to an exemplary embodiment of the present application. FIG. 9 is another section view of an atomization device according to an exemplary embodiment of the present application. As shown in FIG. 7 FIG. 9, the atomization device 200 may also include a sleeve shell 220. The base 120 may be assembled in the sleeve shell 220, and the sleeve shell 220 is sleeved outside the liquid reservoir 210. In the practice assembling process, the sleeve shell 220 may be sleeved from the bottom of the base 120 onto the outside of the base 120, and the liquid reservoir 210 may be sleeved from the top of the base 120 onto the outside of the base 120. The liquid reservoir 210 is located between the inner wall of the sleeve shell 220 and the outer wall of the base 120.

[0056] It should be understood that, in a first aspect, the sleeve shell 220 may play a certain protection effect on the liquid reservoir 210 and the base 120, thereby preventing foreign matters from colliding the liquid reservoir 210 and the base 120; and in a second aspect, the sleeve shell 220 may serve as a decorative shell.

[0057] As shown in FIG. 7, in a cast that the atomization device 200 includes the sleeve shell 220, the sleeve shell 220 may be provided with the first matching portion 230, the liquid reservoir 210 is provided with the second matching portion 240, and the first matching portion 230 removably matches with the second matching portion 240. In practice applications, the liquid reservoir 210 is sleeved on the base 120, and the sleeve shell 220 is sleeved on the outside of the liquid reservoir 210. The first matching portion 230 and the second matching portion 240 match with each other, thereby achieving fast assembling between the liquid reservoir 210 and the sleeve shell 220. Moreover, since the matching manner between the first matching portion 230 and the second matching portion 240 is the removable matching manner, it is convenient for fast disassembling / removing between the liquid reservoir 210 and the sleeve shell 220. That is, by the removable matching manner between the first matching portion 230 and the second matching portion 240, it is possible to effectively improve the assembling / disassembling efficiency between the liquid reservoir 210 and the sleeve shell 220.

[0058] It should be noted that, the first matching portion 230 mentioned above may include one of a protrusion block 260 and a clamping groove 250, the second matching portion 240 may include the other of the protrusion block 260 and the clamping groove 250, and the protrusion block 260 matches with the clamping groove 250. Therefore, through the matching structure between the protrusion block 260 and clamping groove 250, the assembling / disassembling efficiency between the liquid reservoir 210 and the sleeve shell 220 is effectively improved, or the assembling / disassembling efficiency between the liquid reservoir 210 and the base 120 is effectively improved. The specific configuration of the protrusion block 260 and the clamping groove 250 will be introduced hereinafter.

It should be understood that, in a case that the clamping groove 250 is provided on the base 120, the clamping groove 250 is a blind groove. Therefore, it may be ensured that the matching cavity 121 of the base 120 has an enclosed structure on all sides.
