Abstract

An exemplary atomizer includes a liquid supply, a mouthpiece at a first end of the liquid supply, an air pipe, a liquid supply, and an atomizing device at an opposite second end. The atomizing device includes a main body, a liquid conducting element, and a heating element. The main body has an atomizing chamber. The liquid supply defines at least one air inlet at the first end. The air pipe and the liquid supply cooperatively define an annular air passage. The main body defines at least one liquid inlet and at least one air hole. The air passage is in communication with the atomizing chamber via the at least one air hole. The liquid supply has a housing, and the housing defines liquid outlets. The liquid outlets communicates with the at least one liquid inlet, and the liquid conducting element is configured for absorbing the tobacco liquid.

First claim

What is claimed is:

1. An atomizer, comprising:
a liquid supply configured for storing tobacco liquid;
a mouthpiece at a first end of the liquid supply;
an air pipe;
an atomizing device at an opposite second end, the atomizing device comprising:
a main body having an atomizing chamber, the air pipe connecting the atomizing chamber and the mouthpiece;
a liquid conducting element in the atomizing chamber; and
a heating element in contact with the liquid conducting element;

wherein the liquid supply defines at least one air inlet at the first end, the air pipe and the liquid supply cooperatively define an annular air passage, the air passage is in communication with the air inlet, the main body defines at least one liquid inlet and at least one air hole, the air passage is in communication with the atomizing chamber via the at least one air hole, the liquid supply has a housing, the housing defines liquid outlets matching with the at least one liquid inlet, the liquid outlets communicates with the at least one liquid inlet, and the liquid conducting element is configured for absorbing the tobacco liquid flowed through the liquid outlets and the at least one liquid inlet from the liquid supply.

2. The atomizer according to claim 1 , wherein the liquid conducting element is made of cotton, glass fiber or ceramic material.

3. The atomizer according to claim 1 , wherein the heating element is oriented along a direction parallel to an axial direction of the main body.

4. The atomizer according to claim 1 , wherein the heating element is oriented along a direction perpendicular to an axial direction of the main body.

5. The atomizer according to claim 1 , wherein the air pipe is nested in the liquid supply, the air pipe and the liquid supply cooperatively define a gap therebetween, and the gap serves as the air passage.

6. The atomizer according to claim 1 , wherein the liquid supply is made of transparent material.

7. The atomizer according to claim 1 , further comprising a casing tube nesting the liquid supply and the atomizing device.

8. An electronic cigarette, comprising:
an atomizer according to claim 1 ; and
a power supply configured for supplying the atomizer power.

9. The atomizer according to claim 1 , wherein the main body comprises at least one protrusion, the at least one protrusion protrudes into the air passage, the at least one protrusion is coupled with the housing of the liquid supply by interference fit, and the at least one liquid inlet is defined in a corresponding protrusion.

10. The atomizer according to claim 9 , wherein the at least one air hole is positioned below the at least one liquid inlet, external air enters the at least one air inlet, then passes the air passage, the at least one air hole, and reaches the atomizing chamber.
