Abstract

An electronic cigarette is provided, comprising an outer sleeve and a suction nozzle cap mounted at one end of the outer sleeve; wherein, the suction nozzle cap is sheathed on the outer sleeve, and an inner wall of the suction nozzle cap is located at the outside of an outer wall of the outer sleeve. The suction nozzle cap is sheathed on the outer sleeve, the disassembly of the suction nozzle cap is more convenient, and the structure design of the suction nozzle cap is diversified.

First claim

What is claimed is:

1. An electronic cigarette, comprising an outer sleeve and a suction nozzle cap mounted at one end of the outer sleeve; wherein, the suction nozzle cap is sheathed on the outer sleeve, and an inner wall of the suction nozzle cap is located on an outer wall of the outer sleeve;
wherein, the suction nozzle cap includes an end cap facing an opening end of the outer sleeve and a combined body sheathed on the outer sleeve, wherein the end cap and the combined body are integrated, and the end cap defines a smoking hole: an edge of an inner wall of the end cap abuts with the opening end of the outer sleeve, and a central axis of the smoking hole deviates from a central axis of the outer sleeve: a first reserved space is formed between the inner wall of the end cap and the opening end of the outer sleeve: an annular bulge extends from an edge of the end cap corresponding to a circumference of the smoking hole to the opening end of the outer sleeve axially;
wherein, the combined body includes a first combined part and a second combined part, a crease line is formed between the first combined part and the second combined part, when either of the two combined parts is rotated or forced in the first use, the crease line breaks and shows that the electronic cigarette has been ever opened: the second combined part is sheathed on the outside of the outer sleeve and can move along the outer sleeve.

2. The electronic cigarette according to claim 1 , wherein, a cross section of the combined body is round, oval or polygonal.

3. The electronic cigarette according to claim 1 , wherein, an axial length of the combined body ranges from 20 mm to 33 mm.

4. The electronic cigarette according to claim 1 , wherein, a flange configured to abut against the opening end of the outer sleeve is formed on the combined body.

5. The electronic cigarette according to claim 1 , wherein, an inner wall of the combined body and the outer wall of the outer sleeve form any one of interference fit, buckled connection, and threaded connection.

6. The electronic cigarette according to claim 5 , wherein, at least one convex rib or at least one groove is radially formed on a circumference of a portion of the outer wall of the outer sleeve that contacts the inner wall of the combined body, and at least one groove or at least one convex rib is radially formed on the inner wall of the combined body correspondingly, and the combined body and the outer sleeve are mutually buckled.

7. The electronic cigarette according to claim 5 , wherein, an external thread or an internal thread is radially formed on a circumference of a portion of the outer wall of the outer sleeve that contacts the inner wall of the combined body, an internal thread or an external thread is radially formed on the inner wall of the combined body correspondingly, and the combined body and the outer sleeve are thread-connected.

8. The electronic cigarette according to claim 5 , wherein, the combined body is elastic, and the combined body and the outer sleeve form interference fit.

9. The electronic cigarette according to claim 1 , wherein, a first chamfer configured to facilitate the outer sleeve to insert into the combined body is formed at an edge of the inner wall of an end of the combined body away from the end cap.

10. The electronic cigarette according to claim 9 , wherein, a sealing ring is sheathed on one end of the outer sleeve facing the suction nozzle cap, a second reserved space is formed between one end of the sealing ring near the suction nozzle cap and the opening of the outer sleeve, and a third reserved space is formed between one end of the sealing ring away from the suction nozzle cap and an atomizer received in the outer sleeve.

11. The electronic cigarette according to claim 10 , wherein, the sealing ring defines a first containing chamber and a through hole; the first containing chamber is configured for condensing tobacco tar, and the first containing chamber is shaped as a round table and is formed by gradually reducing a diameter of an edge of the sealing ring; the through hole communicates with the smoking hole, and is aligned with or deviates from the smoking hole.

12. The electronic cigarette according to claim 11 , wherein, a third chamfer configured to facilitate the outer sleeve to insert into the sealing ring is formed at an edge of the outer wall of one end of the sealing ring away from the smoking hole.
