Detailed ways

Below in conjunction with accompanying drawing embodiment, the present invention will be further described:

Embodiment one

As shown in Figures 1 and 2, an electronic cigarette pod with a closed system includes a cylindrical shell 5, and the center of the shell 5 is provided with a through hole 10 along the axial direction, and the peripheral wall of the through hole 10 is composed of the outer wall of the shell 5 Cavity 6, which contains e-liquid; the right end of the cavity is sealed, the left end is open, and the peripheral wall of the through hole 10 at the opening is shorter than the outer wall of the casing 5;

At the opening, a cylindrical inner wall cavity 2 is set, the outer diameter of the left end of the inner wall cavity 2 is adapted to the inner diameter of the outer wall of the outer shell 5, and the left end of the inner wall cavity 2 and the outer wall of the outer shell 5 are closely fitted. The outer diameter of the middle part of the inner wall cavity 2 is less than the outer diameter of the left end of the inner wall cavity 2, but greater than the diameter of the through hole 10; , but less than the outer diameter of the middle part of the inner wall cavity 2; on the wall of the middle part of the inner wall cavity 2, a liquid outlet hole 21 is arranged up and down, and the inner wall cavity 2 communicates with the cavity body 6 through two liquid outlet holes 21;

In the cylindrical inner wall cavity 2, sealing rings 8 are respectively set between the left and right sides of the liquid outlet 21 and the cylindrical inner core 3; the first sealing ring is set between the left end of the inner wall cavity 2 and the outer wall of the shell Pad 9 ; the second sealing pad 7 is set between the right end of the inner wall cavity 2 and the peripheral wall of the through hole 10 .

In the inner wall cavity 2, at the joint between the middle part and the right end of the inner wall cavity 2, a compression spring 4 is set against the left end of the compression spring 4, and a cylindrical inner core 3 is set against the inner core 3, and the inner core 3 and the inner wall cavity 2 are tightly fitted. ; The central axis of the cylindrical inner core 3 is provided with a second air hole;

The cylindrical inner core 3 and the left end of the inner wall cavity 2 are buckled with a circular sealing cover 1, and a third air hole is opened on the sealing cover 1; the sealing cover 1 and the outer shell 5 are interference fit; the first air hole and the second air hole , and the third air hole are all communicated with the through hole 10 .

The shell 5, the inner wall cavity 2, the inner core 3, and the sealing cover 1 can be made of food-grade plastic or metal.

The working process of the present invention is as follows:

As shown in Figures 1 and 2, if electronic cigarette liquid is needed, the chuck of the matching atomizer will pass through the sealing cover 1 and then move to the right against the inner core 3, and the sealing ring 8 will follow the inner core 3 Moving to the right together, the compression spring 4 is compressed; when the left end of the inner core 3 passes through the liquid outlet hole 21 on the inner wall cavity 2, the e-liquid flows out from the inner wall cavity 2 through the liquid outlet hole 21. The sealing cover 1 is used to prevent the inner core 3 from being ejected due to the action of the compression spring 4 . After the e-cigarette liquid is filled, the clamp of the atomizer is released, and the sealing ring 8 and the inner core 3 move to the left and restore together under the rebound of the compression spring 4, and the liquid outlet hole 21 is covered by the sealing ring 8 and the inner core. 3 is closed, the smoke liquid will no longer flow out from the inner wall cavity 2.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention to other forms. Any skilled person who is familiar with this profession may use the technical content disclosed above to change or modify the equivalent of equivalent changes. Example. However, any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still belong to the protection scope of the technical solution of the present invention.
