Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, and particularly refers to a sealing structure of an electronic cigarette oil bottle. Background Art

[0002] An electronic cigarette atomizes e-liquid through an atomization core assembly for users to inhale. Therefore, the amount of e-liquid determines the usage duration of the electronic cigarette. To meet consumers' demand for large capacity, some electronic cigarettes are designed with a structure that can refill e-liquid through an oil bottle. Currently, most electronic cigarette oil bottles are sealed with silica gel; however, due to the characteristics of silica gel, it is easy to fall off from the oil bottle mouth. Summary of the Utility Model

[0003] The technical problem solved by the utility model is to provide a sealing structure of an electronic cigarette oil bottle, which can prevent the sealing silica gel of the oil bottle from falling off.

[0004] The technical solution adopted by the utility model to solve the above technical problem is as follows:

[0005] The sealing structure includes an oil bottle, an oil bottle upper cover and a sealing silica gel; the oil bottle upper cover is arranged at the opening end of the oil bottle; the sealing silica gel is sleeved on the oil bottle upper cover; an inwardly protruding barb is arranged at the bottom end of the sealing silica gel; a concave ring is correspondingly arranged in an inverted manner on the outer periphery of the oil bottle upper cover; the inverted buckle and the concave ring are matched with each other.

[0006] The structure further includes a steel ring; the steel ring is sleeved outside the sealing silica gel, and the bottom end of the steel ring is flush with the bottom end of the sealing silica gel.

[0007] The bottom end of the steel ring is in interference fit with the bottom end of the sealing silica gel.

[0008] In the utility model, the sealing silica gel is sleeved outside the oil bottle upper cover of the oil bottle; the bottom end of the sealing silica gel and the oil bottle upper cover are matched through an inverted buckle and a concave ring; and the sealing silica gel is firmly fixed on the oil bottle upper cover through the interference fit between the steel ring outside the sealing silica gel and the bottom end of the sealing silica gel. Brief Description of the Drawings

[0012] Figure 3 It is a cross-sectional view of the completed state of the assembly of the electronic cigarette oil bottle of the utility model;

[0013] Figure 4 It is a three-dimensional view of the completed state of the assembly of the electronic cigarette oil bottle of the utility model. Detailed implementation mode

[0014] As Figures 1-3 shown, the e-cigarette oil bottle sealing structure of the present utility model includes an oil bottle 1, an oil bottle upper cover 2, a sealing silica gel 3 and a steel ring 4. The oil bottle upper cover 2 is arranged at the opening end of the oil bottle 1; the sealing silica gel 3 is sleeved on the oil bottle upper cover 2; the steel ring 4 is sleeved outside the sealing silica gel 3.

[0015] Specifically, an inwardly protruding barb 31 is provided at the bottom end of the sealing silica gel 3; a concave ring 21 is correspondingly arranged in an inverted manner on the outer periphery of the oil bottle upper cover 2; the barb 31 and the concave ring 21 are matched with each other. The bottom end of the steel ring 4 is flush with the bottom end of the sealing silica gel 3, and the bottom end of the steel ring 4 and the bottom end of the sealing silica gel 3 are in interference fit. Therefore, the barb 31 and the concave ring 21 are stably fitted together.

[0016] During assembly, as Figure 1 shown, first install the stainless steel steel ring 4 on the sealing silica gel 3 to form a component; then assemble this component onto the oil bottle upper cover 2, and the state of the component of the steel ring 4 and the sealing silica gel 3 after being installed is as Figure 2 shown. At this time, there is a certain distance between the lower end surface of the steel ring 4 and the sealing silica gel 3. Then, continue to move the steel ring 4 downward until the lower end surface of the steel ring 4 is flush with the lower end surface of the sealing silica gel 3; the state at this time is as Figure 3 shown. The interference amount between the stainless steel steel ring 4 and the sealing silica gel 3 is used for fixation; the outer ring of the inverted structure of the sealing silica gel 3 is sleeved with the stainless steel steel ring 4 to achieve the purpose of preventing the sealing silica gel 3 from falling off.

[0017] The above embodiments are descriptions of the specific implementation modes of the present utility model, not limitations on the present utility model; all equivalent transformations obtained according to the above descriptions should be within the protection scope of the present utility model.
