Description

An electronic cigarette sealing ring with multiple corrugations

technical field

The embodiment of the utility model relates to the field of electronic cigarettes, in particular to an electronic cigarette sealing ring with a plurality of corrugations.

Background technique

E-cigarette is an electronic product that uses heating wire to heat smoke liquid and atomize it, providing smokers with a substitute for cigarettes. The heated smoke liquid turns into aerosol, and after passing through the ventilation tube, it reaches the outside of the electronic cigarette from the opening of the nozzle cover. When manufacturing electronic cigarettes, it is generally necessary to use a sealing ring on the atomizer of the electronic cigarette to prevent the liquid from leaking from the nozzle cover.

Since the outer surface of the smoke sealing ring of the existing electronic cigarette is provided with only one corrugation, when the corrugation is deformed by force, there will be a gap between the corrugation of the sealing ring and the inner wall of the housing, and the smoke liquid will flow from the gap between the sealing ring and the inner wall. The gap leaks, resulting in leakage.

Example 1

As shown in Figures 1, 2, and 3, the electronic cigarette sealing ring with multiple ribs includes an upper sealing block 10 and a lower sealing block 20, and the lower sealing block 20 is arranged below the upper sealing block 10 and connected to the upper sealing block 10. The lower ends are connected, and the cross-sections of the upper sealing block 10 and the lower sealing block 20 are oval. In this embodiment, the upper sealing block 10 and the lower sealing block 20 are integrally formed to reduce production costs. The upper sealing block 10 and the lower sealing block 20 are made of silica gel, and the upper sealing block 10 and the lower sealing block 20 made of silica gel have excellent characteristics of good elasticity and high temperature resistance. The inside of the upper sealing block 10 is provided with a first vent hole 11 along the axial direction, and the inside of the lower sealing block 20 is provided with a second vent hole 21 communicating with the first vent hole 11 along the axial direction, wherein the first vent hole 11 and The second air hole 21 is arranged coaxially, and the inner diameter of the first air hole 11 is larger than the inner diameter of the second air hole 21 . The edge of the lower end surface of the upper sealing block 10 is provided with an annular first insertion groove 12, the edge of the lower end surface of the lower sealing block 20 is provided with an annular second insertion groove 22, and the outer peripheral surface of the upper sealing block 10 is provided with a plurality of annular The corrugations 13 are evenly distributed on the outer peripheral surface of the upper sealing block 10, and the distance between two adjacent corrugations 13 is 1 mm. An annular groove 14 is formed between two adjacent corrugations 13, the depth of the groove 14 is 0.1-0.3 mm, preferably 0.17 mm, and the width of the groove 14 is 0.5-0.8 mm, preferably 0.55 mm.
