[0003] However, the interference fit strength between each interference ring on the silicone ring and the housing is the same. When the housing is deformed, it is easy to cause sealing failure. Since the interference fit strength between each interference ring on the silicone ring and the housing is the same, when one interference ring fails, the whole fails. Content of the Utility Model

Detailed implementation manners

[0024] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant accompanying drawings.

[0025] This application proposes a leak-proof sealing structure. Please refer to Figure 1 and Figure 2 , including: a sealing sleeve 10, a housing 11 and a bracket 12. An oil tank 13 is arranged inside the housing 11, and the oil tank 13 is used for storing liquid. The bracket 12 and the sealing sleeve 10 are arranged below the oil tank 13, and the sealing sleeve 10 makes the oil tank 13 form a closed space. The sealing sleeve 10 has a certain elasticity and is elastically and closely matched with the housing 11, and can compensate for the fitting gap in time. A plurality of interference collars 20 extend out in the fitting gap between the sealing sleeve 10 and the housing 11, and the setting of the interference collars 20 is to prevent oil leakage from the gap between the housing 11 and the sealing sleeve 10. When the housing 11 undergoes micro-deformation due to temperature change, extrusion, impact, etc., the elastic sealing sleeve 10 and the interference collars 20 make the housing 11 and the sealing sleeve 10 closely fit. Moreover, the interference degree of each interference collar 20 with the housing 11 gradually increases in the direction away from the oil tank 13. Among them, the stronger the interference degree of the interference collar 20, the greater the interference thickness of the interference collar 20. After the housing 11 undergoes micro-deformation, when one interference collar 20 fails, the next interference collar 20 with a stronger interference degree can be closely fitted with the inner surface of the deformed housing 11, so that the sealing effect between the interference collar 20 and the housing 11 remains effective, thereby enhancing the oil leakage prevention effect of the interference collar 20, and thus ensuring the tightness of the oil tank 13.

[0026] Furthermore, the interference collars 20 are arranged at equal intervals, resulting in a compact structure and strong sealing performance.

[0027] In one embodiment, please refer again to Figure 1 and Figure 2 The sealing sleeve 10 includes a disc 21, an outer ring 22, and a middle ring 23. The outer ring 22 and the middle ring 23 are respectively connected to the lower surface of the disc 21. The outer ring 22 is at the outermost side of the disc 21. The interference ring 20 is arranged on the outer side of the outer ring 22 so that the interference ring 20 on the outer ring 22 can fit tightly with the housing 11, filling the gap between the sealing sleeve 10 and the housing 11, and further ensuring the sealing performance.

[0028] Furthermore, a compensating ring 25 is recessed on the side opposite the interference collar 20 at the bottom of the outer ring 22. This allows the interference collar 20, which has the strongest interference, to use its own elasticity to squeeze against the inner wall of the housing 11. The compensating ring 25 then compresses the interference collar 20, allowing the sealing sleeve 10 to be more easily assembled within the housing 11 by squeezing. The design of the compensating ring 25 allows the sealing sleeve 10 to be equipped with an interference collar 20 with a greater interference thickness.

[0029] Furthermore, the sealing sleeve 10 also includes an inner ring 24, a nozzle 31 mounting hole is opened at the center of the disc 21, the nozzle 31 mounting hole extends downward from the inner ring 24, and the side of the inner ring 24 extends a sealing ring toward the direction close to the nozzle 31 mounting hole.

[0030] In another embodiment, there are three interference rings 20 , and the thicknesses of the three interference rings 20 increase step by step, so that the interference strength becomes stronger and the fit with the inner wall of the shell 11 becomes tighter.

[0031] See also Figure 1 , Figure 2 and Figure 3, this application also provides an e-cigarette atomization component, which includes a heating element 30, a mouthpiece 31, the above-mentioned leak-proof sealing structure, and a conductive electrode 32. The heating element 30 is fixed on the bracket 12, and the electrode 32 is electrically connected to the heating element 30. An external power supply can supply power to the heating element 30 through the electrode 32, and the heating element 30 can atomize the e-liquid in the oil storage chamber 13. The sealing sleeve 10 and the bracket 12 are respectively provided with oil inlet grooves 36 communicating with the oil storage chamber 13, and the e-liquid in the oil storage chamber 13 reaches the heating element 30 through the oil inlet grooves 36 for atomization to form an atomized liquid. The mouthpiece 31 is arranged on the housing 11, the tail of the mouthpiece 31 is connected to the sealing sleeve 10, and the bracket 12 is provided with an atomization air passage 50 communicating with the mouthpiece 31. When the user sucks through the mouthpiece 31, a negative pressure is formed in the housing 11, forcing external air to enter the housing 11. The high-speed air flow mixes with the atomized liquid and is finally sucked out through the atomization air passage 50 from the mouthpiece 31. The e-cigarette atomization component of this application has multiple interference rings 20 to prevent oil leakage from the oil storage chamber 13, and the anti-oil leakage effect is good.

[0032] Further, the e-cigarette atomization component further includes a base 33, the base 33 is arranged below the bracket 12, and the base 33 supports the sealing sleeve 10 and the bracket 12. The base 33 extends a limiting member 34 on its inner side surface, and a limiting notch is recessed at a corresponding position on the outer side of the bracket 12, and the limiting notch is stuck on the limiting member 34, so that the base 33 can be suspended and stuck in the housing 11.

[0033] In an embodiment, the e-cigarette atomization component further includes a silica gel sleeve 35, the silica gel sleeve 35 is sleeved on the heating element 30, and the silica gel sleeve 35 can protect the heating element 30. When the e-cigarette atomization component is impacted, it ensures that the heating element 30 is not impacted and its structure is loose or damaged. And, the base 33 is provided with an electrode 32 through groove, and the electrode 32 is installed in the electrode 32 through groove, so that the upper part of the electrode 32 abuts against and is electrically connected to the heating element 30, and the lower part is electrically connected to the power supply, without using a wire. And the wire is prone to aging under the high temperature generated by the heating element 30 during operation, solving the problem that the wire needs to be replaced due to aging inside, and reducing the number of repairs.

[0034] In addition, a sealing ring 40 is arranged in the fitting gap between the base 33 and the housing 11 to further prevent the e-liquid from leaking onto the power supply below.

[0035] The above embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
