Description

Technical Field

[0001] The present invention relates to the technical field of electronic cigarettes, and in particular to an electronic cigarette oil bottle structure for injection type oil supply. Background Art

[0002] Electronic cigarettes use the atomizer core component to atomize the e-liquid infiltrated into the oil storage cotton for users to inhale. Therefore, the operation of electronic cigarettes requires that there is e-liquid in the oil storage cotton. However, in some countries or regions, due to their regulatory restrictions, the oil storage cotton cannot be filled with e-liquid during storage and transportation before use. Summary of the invention

[0003] The technical problem solved by the present invention is to provide an electronic cigarette oil bottle structure with injection-type oil supply, which can realize oil filling of the oil storage cotton only when in use.

[0004] The technical solution of the present invention to solve the above technical problems is:

[0005] The oil bottle of the structure comprises an oil storage cup, a cup cover and sealing silicone; the cup cover is arranged at the cup mouth of the oil storage cup, and the sealing silicone is closely arranged on the top of the cup cover; the characteristic is that it also comprises a push cover; the push cover can move axially along the cup cover and the oil storage cup; an oil through hole is arranged at the center of the cup cover push cover, which passes through the oil storage cup and the top of the cup cover.

[0006] The upper end of the push cover is formed into a columnar shape matching the inner side of the cup cover, and the lower end of the push cover is formed into a generally square shape matching the inner side of the oil storage cup; the columnar upper end of the push cover can slide in the cup cover, and the square lower end can slide in the oil storage cup.

[0007] A sealing rubber ring is arranged between the upper end of the push cover and the inner side of the cup cover; and a push cover sealing silica gel is arranged between the bottom end of the push cover and the inner side of the oil storage cup.

[0008] The inner diameter of the top end of the opening of the oil storage cup is expanded outward to form a step; the step limits the sliding stroke of the push cover into the oil storage cup.

[0009] The cup cover and the top end of the oil storage cup form a snap-fit ​​connection.

[0010] The top surface of the sealing silica gel is in the shape of a film and is formed with a petal-shaped incision.

[0011] After the oil bottle of the present invention is assembled with the rest of the electronic cigarette, the oil guide column connected to the oil storage cotton pierces the sealing silicone and pushes the push cover to slide into the oil storage cup to the bottom of the stroke, so that the smoke oil in the oil storage cup flows into the oil storage cotton along the oil guide column under the action of pressure. When not assembled, the oil storage cotton can be kept free of smoke oil. Compared with other electronic cigarettes that are not shipped with oil filling, the structure of the present invention can quickly inject smoke oil into the oil storage cotton without oil, without waiting for a long time for the smoke liquid to flow into the atomization core, so as to achieve rapid core lubrication, shorten the waiting time for the user to assemble the oil bottle into the smoking device for core lubrication, and the amount of smoke oil injected can be stably controlled, and it is not easy to inject excessive smoke oil to cause leakage; it can improve the user experience.

[0021] like Figure 1-3 As shown in Figures 8 and 9, the sealing structure of the electronic cigarette oil bottle of the present invention comprises a sealing silica gel 1, a cup cover 2, a push cover 3, an oil storage cup 4, a sealing rubber ring 5 and a push cover sealing silica gel 6; the cup cover 2 is arranged at the mouth of the oil storage cup 4 and is snap-fitted to the top of the oil storage cup 4. The sealing silica gel 1 is closely arranged at the top of the cup cover 2; the top surface of the sealing silica gel 1 is in the shape of a film and is formed with a petal-shaped incision.

[0022] The upper end of the push cover 3 is formed into a columnar shape matching the inner side of the cup cover 2, and the lower end of the push cover 3 is formed into a substantially square shape matching the inner side of the oil storage cup 4. A sealing rubber ring 5 is provided between the upper end of the push cover 3 and the inner side of the cup cover 2; a push cover sealing silica gel 6 is provided between the lower end of the push cover 3 and the inner side of the oil storage cup 4. The columnar upper end of the push cover 3 can slide in the cup cover 2, and the square lower end can slide in the oil storage cup 4.

[0023] The inner diameter of the top end of the opening of the oil storage cup 4 is expanded outward to form a step 41 ; the step 41 limits the sliding stroke of the push cover 3 into the oil storage cup 4 .

[0024] An oil hole is arranged at the center of the push cover 3 to pass through the oil storage cup 4 and the top end of the cup cover 2 .

[0025] When assembling the oil bottle and the rest of the electronic cigarette, the relative positions shown in 4 and 5 can be formed. Then, push the oil bottle upward; the structure and position after pushing in are as shown in FIG. Figure 6 , 7 shown.

[0026] During and after the oil bottle is assembled, the oil guide column 8 pierces the sealing silicone 1 and pushes the push cover 3 to slide into the oil storage cup 4 to the bottom of the stroke; at this time, the push cover sealing silicone 6 pushes the step 41. Under the action of pressure, the smoke oil in the oil storage cup 4 flows into the oil storage cotton 7 along the oil guide column 8, thereby achieving oil filling of the oil storage cotton 7.

[0027] The above embodiments are descriptions of specific implementation methods of the present invention, and are not limitations of the present invention; all equivalent modifications that can be obtained based on the above description should be within the protection scope of the present invention.
