Abstract

An electronic cigarette includes a shell and a mouthpiece. The external wall of the shell has an air inlet. An atomizer and a liquid-supply are in contact with each other. The air inlet, atomizer, and an aerosol passage are interconnected.

First claim

The invention claimed is:

1. An electronic atomization device, comprising:
a cylindrical housing containing liquid and having a mouthpiece coaxial with a longitudinal axis of the housing;
at least one air inlet for allowing air to flow into the housing;
a cylindrical porous body surrounding a heating wire and a cylindrical atomization chamber, with the heating wire inside of the cylindrical atomization chamber, and the liquid contacting the cylindrical porous body;
wherein the cylindrical porous body has a central axis co-axial with the longitudinal axis of the housing; and
an air passage extends from the at least one air inlet to the mouthpiece.

2. The device of claim 1 with the cylindrical porous body comprising a fiber material.

3. The device of claim 2 further including a manually operated switch electrically connected to an electronic circuit board in the housing.

4. The device of claim 2 with the liquid comprising propylene glycol.

5. The device of claim 1 with the housing having a first section attached to a second section, and with the liquid in the second section.

6. The device of claim 5 wherein the liquid is vaporized only via heating by the heating wire.

7. The device of claim 1 wherein the air passage extends through the atomization chamber to the mouthpiece.

8. The device of claim 7 with the cylindrical porous body, and a gas vent leading into the mouthpiece, co-axial with the longitudinal axis of the housing.

9. The device of claim 8 with the heating wire in the air passage.

10. An electronic atomization device, comprising:
a cylindrical housing having a refillable liquid-supply;
at least one air inlet for allowing air to flow into the cylindrical housing;
a cylindrical porous body comprising a fiber material surrounding a heating wire and a cylindrical atomization chamber, with the heating wire inside of the cylindrical atomization chamber, and liquid from the liquid-supply contacting the cylindrical porous body for moving liquid from the liquid-supply to the heating wire; and
an air passage extending from the at least one air inlet through the cylindrical atomization chamber and through a gas vent, with the cylindrical porous body, the cylindrical atomization chamber and the gas vent co-axial with the longitudinal axis of the cylindrical housing.

11. The device of claim 10 further including a manually operated switch electrically connected to an electronic circuit board in the housing.

12. The device of claim 10 wherein the liquid is vaporized only via heating by the heating wire.

13. The device of claim 12 with the liquid-supply comprising propylene glycol.

14. The device of claim 13 further including a display screen on the housing.

15. An electronic atomization device, comprising:
a cylindrical refillable bottle for holding a liquid;
a cylindrical porous body comprising a fiber material surrounding a heating wire and a cylindrical atomization chamber, with the heating wire inside of the cylindrical atomization chamber, and the liquid from the refillable bottle contacting the porous body;
a gas vent co-axial with the cylindrical atomization chamber; and
an air passage extending through the atomization chamber and the gas vent to a mouthpiece, with the air passage parallel to a longitudinal axis of the cylindrical refillable bottle.

16. The device of claim 15 with the heating wire in the air passage.

17. The device of claim 16 with the heating wire positioned to come into contact with the liquid.

18. The device of claim 17 further including a manually operated switch electrically connected to an electronic circuit board in the housing and wherein the liquid is vaporized only via heating by the heating wire.
