Abstract

An exemplary atomizer of an electronic cigarette includes an atomizing tube and an atomizing assembly arranged in the atomizing tube. The atomizing assembly includes a ceramic tube and a heating element. The heating element is in contact with an inner surface of the ceramic tube. The ceramic tube defines a plurality of liquid absorption hole.

First claim

What is claimed is:

1. An atomizer of an electronic cigarette, comprising:
an atomizing tube; and
an atomizing assembly arranged in the atomizing tube, the atomizing assembly comprising a ceramic tube, a heating element and wires for being electrically connected between the heating element and a power supply of the atomizer, the heating element extending along a longitudinal direction of the ceramic tube for a preset length and an outer surface thereof being completely in contact with an inner surface of the ceramic tube, the ceramic tube defining a plurality of liquid absorption hole, the wires respectively extending from the heating element toward one end of the ceramic tube along the inner wall of the ceramic tube, and then extending from the one end of the ceramic tube toward the other end of the ceramic tube along an outer wall of the ceramic tube.

2. The atomizer of claim 1 , wherein the heating element comprises a heating wire, the heating wire is wound to form a coil, and the coil is received in the ceramic tube to have the entire heating wire being completely in contact with the inner surface of the ceramic tube.

3. The atomizer of claim 1 , wherein the heating element and the ceramic tube are integrally formed.

4. The atomizer of claim 1 , wherein the ceramic tube is uprightly arranged in the atomizing tube, and the ceramic tube defines an air passage therein.

5. The atomizer of claim 4 , wherein the air passage has a shape of truncated cone.

6. The atomizer of claim 1 , further comprising an air pipe, wherein the ceramic tube communicates with the air pipe.

7. The atomizer of claim 1 , further comprising a liquid storage element wrapping around the ceramic tube and being positioned between the ceramic tube and the atomizing tube.

8. The atomizer of claim 7 , further comprising an air pipe disposed next to the atomizing assembly in the atomizing tube, a liquid chamber for accommodating tobacco liquid being defined cooperatively between the air pipe and the atomizing tube.

9. The atomizer of claim 8 , wherein at least one liquid outlet is defined at one end of the air pipe engaging with the atomizing assembly, the tobacco liquid accommodated in the liquid chamber flows to the liquid storage element through the at least one liquid outlet.

10. The atomizer of claim 1 , further comprising a silicone holder, wherein the wires are connected with two ends of the heating element, and the ceramic tube is engaged with the silicone holder.

11. An electronic cigarette comprising:
an atomizer according to claim 1 ; and
a battery assembly for powering the atomizer.

12. The electronic cigarette of claim 11 , wherein the heating element comprises a heating wire, the heating wire is wound to form a coil, and the coil is received in the ceramic tube.

13. The electronic cigarette of claim 11 , wherein the heating element and the ceramic tube are integrally formed.

14. The electronic cigarette of claim 11 , wherein the ceramic tube is uprightly arranged in the atomizing tube, and the ceramic tube defines an air passage therein.

15. The electronic cigarette of claim 14 , wherein the air passage has a shape of truncated cone.

16. The electronic cigarette of claim 11 , further comprising an air pipe, wherein the ceramic tube communicates with the air pipe.

17. The electronic cigarette of claim 11 , further comprising a liquid storage element wrapping around the ceramic tube.

18. The electronic cigarette of claim 11 , further comprising a silicone holder, wherein the wires are connected with two ends of the heating element, and the ceramic tube is engaged with the silicone holder.

19. The atomizer of claim 1 , wherein the heating element is adhered to the inner surface of the ceramic tube in the form of a printed circuit board.
