AI Technical Summary

Technical Problem

The silicone sealant in existing e-cigarette cartridges tends to shift during use, causing a foreign object sensation and reducing the user experience.

Method used

A cup-shaped part is formed at the center of the e-liquid cartridge holder. The bottom of the cup-shaped part is provided with e-liquid cartridge filling and sealing silicone, and an axial oil inlet groove is provided on the side wall. The size of the oil inlet groove is larger than the size of the silicone, so as to ensure that the silicone is fixed at the bottom of the cup-shaped part during use, forming an e-liquid outflow channel.

Benefits of technology

This effectively prevents the silicone sealant from shifting inside the oil cartridge casing, thus improving the user experience.

Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and specifically to a sealing structure for electronic cigarette cartridges. Background Technology

[0002] E-cigarette cartridges typically consist of a cartridge shell and a cartridge holder; the holder is positioned to seal the opening of the cartridge shell. A silicone sealant for filling the cartridge is also located on the holder. During use, this silicone sealant is pushed into the cartridge shell, opening the cartridge. While this design allows e-liquid to flow out, the silicone sealant remains inside the cartridge shell and is not fixed in place. This causes the silicone sealant to move around within the cartridge shell during use, creating a foreign object sensation and reducing the user experience. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a sealing structure for electronic e-cigarette cartridges, which can avoid the feeling of foreign objects after the cartridges are assembled and used.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is:

[0005] It includes a fuel cartridge shell and a fuel cartridge support; the fuel cartridge support is sealed at the opening of the fuel cartridge shell; the center of the fuel cartridge support forms a cup-shaped part with the opening facing outward and the bottom inside the space enclosed by the fuel cartridge support and the fuel cartridge shell; the opening of the cup-shaped part is provided with fuel cartridge oil filling and sealing silicone; an oil inlet groove is provided on the side wall between the bottom of the cup-shaped part and the fuel cartridge oil filling and sealing silicone.

[0006] The cup-shaped portion is a frustum-shaped cone with a large diameter at the opening and a small diameter at the bottom.

[0007] The oil inlet groove is a through groove arranged along the axial direction; three or more are arranged in the circumferential direction; the axial dimension of the oil inlet groove is larger than the axial dimension of the oil ball sealing silicone.

[0008] The oil cartridge holder is provided with silicone oil cartridge holder between the oil cartridge holder and the inner wall of the oil cartridge shell.

[0009] When the e-liquid cartridge is opened and in use, the silicone sealing agent is secured at the bottom of the cup-shaped part of the cartridge holder; at this time, the e-liquid can be drained through the inlet groove. This design effectively avoids the feeling of foreign objects caused by the silicone sealing agent being loose and moving around inside the cartridge after opening and use. This design improves the user experience. Attached Figure Description

[0016] The following embodiments are descriptions of specific implementations of the present utility model. These descriptions are intended to facilitate understanding of the technical solutions of this application by those skilled in the art and are not intended to limit the scope of protection of the technical solutions of the present utility model. All equivalent transformations that can be obtained from the description of the embodiments of the present utility model should be within the scope of protection of the present utility model.

[0017] like Figure 1-5 As shown, the electronic e-cigarette cartridge of this utility model includes a cartridge shell 1 and a cartridge holder 2; the cartridge holder 2 is sealed at the opening of the cartridge shell 1. A cartridge holder silicone 4 is disposed between the cartridge holder 2 and the inner wall of the cartridge shell 1. The cartridge holder silicone 4 achieves a seal at the joint between the cartridge holder 2 and the cartridge shell 1.

[0018] A cup-shaped portion 21 with an opening facing outward and its bottom inside the space enclosed by the oil cartridge holder 2 and the oil cartridge shell 1 is formed at the center of the oil cartridge holder 1; an oil cartridge filling and sealing silicone 3 is provided at the opening of the cup-shaped portion 21.

[0019] An oil inlet groove 23 is provided on the side wall between the bottom 22 of the cup-shaped portion 21 and the oil-filling sealing silicone 3. The oil inlet groove 23 is a through groove arranged along the axial direction; three or more are arranged in the circumferential direction; the axial dimension of the oil inlet groove 23 is larger than the axial dimension of the oil-filling sealing silicone 3. The cup-shaped portion 21 is a frustum-shaped cone with a large diameter at the opening and a small diameter at the bottom.

[0020] like Figure 3 As shown, when the sealing silicone 3 of the oil cartridge is at the opening of the cup-shaped part 21, the oil inlet groove 23 is located within the space enclosed by the oil cartridge shell 1 and the oil cartridge support 2; the e-liquid inside the oil cup shell 1 cannot flow out through the oil inlet groove 23.

[0021] like Figure 4As shown, when the e-liquid cartridge is assembled and used, the sealing silicone 3 is pushed into the bottom 22 position of the cup-shaped part 21. At this time, a channel for e-liquid to flow out is formed through the oil inlet groove 23 and the opening of the cup-shaped part 21. The sealing silicone 3 is held in place by the side wall of the cup-shaped part 21 at the bottom 22 position of the cup-shaped part 21, thus forming a fixed state.

[0022] The structure of the smoke cartridge and other parts of this utility model is shown in the figure. The other parts are not related to the implementation of the above technical solution, nor are they limited to those shown in the figure; they will not be described in detail here.
