It should be noted that, as long as there is no conflict, the various embodiments and features within each embodiment of this utility model can be combined with each other, and the resulting technical solutions are all within the protection scope of this utility model.

[0023] It should be noted that the specification of this application contains a large number of technical features distributed across various technical solutions. Listing all possible combinations of technical features (i.e., technical solutions) would make the specification excessively lengthy. To avoid this problem, the various technical features disclosed in the above-described utility model content, the various technical features disclosed in the following embodiments and examples, and the various technical features disclosed in the accompanying drawings can be freely combined to form various new technical solutions (all of which are considered to have been described in this specification), unless such a combination of technical features is technically infeasible. For example, one example discloses feature A+B+C, and another example discloses feature A+B+D+E. Features C and D are equivalent technical means that serve the same function, and technically only one needs to be used; they cannot be used simultaneously. Feature E can technically be combined with feature C. Therefore, the solution A+B+C+D should not be considered as described because it is technically infeasible, while the solution A+B+C+E should be considered as described.

[0024] In this utility model, the terms "upper", "lower", "top", "bottom", "inner", "outer", etc., are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing and understanding the technology of this utility model, and are not intended to limit the device or component to have a specific orientation or to be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] like Figure 1-5As shown, this utility model provides a bracket 6, including a bracket body 5, a receiving cavity 501 disposed on the bracket body 5, an air inlet 602 communicating with the receiving cavity 501, and a sealing structure 601 for sealing the receiving cavity 501 and the air inlet 602.

The first sealing element 101, the second sealing element 102, and the sealing gasket 1 are integrally formed with the bracket body 5 and connected to each other. It should be noted that by integrally forming the sealing structure 601 with the bracket 6, the problem of the bracket 6, the first sealing element 101, the second sealing element 102, and the sealing gasket 1 being independent and separate from the bracket body 5 in existing electronic cigarettes, which need to be assembled onto the bracket body 5 sequentially during the production process, is solved. This not only results in low production and assembly efficiency but also incurs additional assembly labor costs and the cost of three sets of molds for production. The receiving cavity 501 is used to receive Figure 6 The atomizer 8 has an air intake 602 for intake and guiding the airflow into the receiving cavity 501. Figure 6 The atomizer 8 provides the airflow required for atomization.

[0026] In some embodiments, the first seal 101, the second seal 102, and the sealing gasket 1 are all made of silicone, while the bracket body 5 is made of plastic.

After cooling, the first seal 101, the second seal 102, and the sealing gasket 1 are formed, and they are connected to each other through the first connector 105 and the second connector 104 respectively.

The housing 7 also has a power supply assembly 704 electrically connected to the atomizer 8. The housing 7 is used to accommodate the support 6 of the cavity 501 and the power assembly 704. The inner wall of the housing 7 abuts against the sealing gasket 1 and the first sealing member 101 to seal the combined gap between the outer wall of the support body 5 and the inside of the housing 7, preventing airflow from leaking from the gap between the first through hole 103 and the air inlet 502. The bottom end of the atomizer 8 abuts against the second sealing member 102 to concentrate the airflow in the gap between the bottom end of the atomizer 8 and the bottom wall of the cavity 501, preventing airflow from leaking from the gap between the outer peripheral wall of the atomizer 8 and the inner peripheral wall of the cavity 501 after entering the cavity 501 from the air guide channel 508, thereby reducing the atomized gas flow rate.
