Rear oiling structure of electronic cigarette cartridge

Abstract

The utility model relates to the technical field of electronic cigarettes, in particular to a rear oil injection structure of an electronic cigarette cartridge. The oil cup comprises an oil cup body, oil storage cotton, lower silica gel and a base. Oil storage cotton is arranged in the oil cup, lower silica gel is sealed below the oil storage cotton, and a base is arranged below the lower silica gel. An oil injection hole is formed in the base; the oil injection hole penetrates through the lower silica gel and is communicated with the oil storage cotton; and oil sealing silica gel is arranged in the oil injection hole. According to the utility model, the cotton shoveling problem in the existing electronic cigarette assembling process is solved; the method can be applied to an electronic cigarette cartridge structure.

Description

Technical Field

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

[0002] Traditional e-cigarette cartridges are filled with e-liquid and then assembled with the base below; this structure is prone to problems such as scraping off the e-liquid during the assembly process, resulting in rework. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a post-filling structure for electronic cigarette cartridges; which can prevent problems such as cotton scraping during the assembly process.

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

[0005] The device includes an oil cup, an oil storage cotton, a lower silicone sealant, and a base. The oil cup contains an oil storage cotton, and a lower silicone sealant is placed below the oil storage cotton. The base is located below the lower silicone sealant. The device is characterized in that: an oil injection hole is provided on the base; the oil injection hole passes through the lower silicone sealant and communicates with the oil storage cotton; and a sealing silicone sealant is placed inside the oil injection hole.

[0006] Two oil injection holes are provided.

[0007] The sealing silicone is in the form of a rubber nail.

[0008] An electrode plate is connected to the bottom of the base; after the electrode plate is assembled with the base, the oil injection hole and the sealing silicone are sealed.

[0009] The electronic cigarette cartridge of this invention can be assembled with a base and then filled with oil through the oil filling hole, which greatly reduces the assembly difficulty; it can also avoid the problem of cotton scraping, improve the product yield, reduce rework, and reduce costs.

[0015] 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.

[0016] like Figure 1-4 As shown, the refill structure of the electronic cigarette cartridge of this utility model includes an oil cup 1, an oil storage cotton 2, a lower silicone 3, a base 4, and an electrode plate 5. The oil cup 1 contains the oil storage cotton 2, the lower silicone 3 is sealed below the oil storage cotton 2, and the base 4 is located below the lower silicone 3.

[0017] Two oil injection holes 41 are provided on the base 4; the oil injection holes 41 pass through the lower silicone 3 and communicate with the oil storage cotton 2; a rubber nail-shaped sealing silicone 42 is provided in the oil injection hole 41. The sealing silicone 42 and the oil injection hole 41 are interference fit.

[0018] An electrode plate 5 is connected below the base 4; after the electrode plate 5 is assembled with the base 4, the oil injection hole 41 and the sealing silicone 42 are sealed.

[0019] During the assembly process, after assembling the base 4 and other components, e-liquid is first added through the filling hole 41; then, the sealing silicone 42 is installed into the filling hole 41. The interference fit between the sealing silicone 42 and the filling hole 41 prevents leakage. Finally, the electrode plate 5 is assembled with the base 4; the electrode plate 5 seals the filling hole 41 and the sealing silicone 42.

[0020] The structure of the remaining parts of the electronic cigarette of this utility model is shown in the figure. The remaining 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.
