Abstract

A device for storing and vaporizing liquid media can comprise an annular liquid media storage tank and a heater configured to vaporize liquid stored in the annular liquid media storage tank.

Claims (78)

1. A cartomizer, comprising:

a liquid storage tank;

a heater coil housing forming a heater coil chamber;

the heater coil housing having a base and a pair of sidewalls, the base having an air inlet;

first and second notches between the pair of sidewalls;

a heater coil wrapped around a wick;

the wick extending through the notches into a recessed pocket between the heater coil housing and a media storage tank wall;

the wick perpendicular to a longitudinal axis of the cartomizer;

electrical contacts extending through the base and electrically connected to the heater coil;

the heater coil housing having an outlet connected to an axial cylindrical neck;

a first end of an inner tube inserted into the axial cylindrical neck;

a second end of the inner tube inserted to a proximal seal;

a chamber between the proximal seal and a mouth piece;

an absorbent material in the chamber; and

the mouthpiece having one or more outlets.

2. The cartomizer of claim 1 wherein a first end of the cartomizer is adapted to be inserted into a battery assembly.

3. The cartomizer of claim 2 wherein the first end of the cartomizer is adapted to connect to a battery assembly via a friction fit.

4. The cartomizer of claim 1 wherein portions of the wick are compressed by ports in the heater coil housing, the ports having an opening less than a diameter of the wick.

5. The cartomizer of claim 1 wherein the recessed pocket is configured to retain liquid by surface tension.

6. The cartomizer of claim 1 further comprising a cover on the first end of the cartomizer to protect connectors on the cartomizer.

7. The cartomizer of claim 1 wherein the absorbent material is a porous material 0.1-6 mm thick.

8. The cartomizer of claim 1 wherein the absorbent material comprises a porous plastic material.

9. The cartomizer of claim 1 wherein the inner tube and the heater coil housing are connected by an interference fit.

10. The cartomizer of claim 1 wherein the mouth piece is attached to the liquid storage tank with a snap fit.

11. The cartomizer of claim 1 having two air inlets.

12. The cartomizer of claim 1 wherein the absorbent material comprises cotton.

13. A cartomizer for use with an electronic smoking device, comprising:

a liquid media storage tank;

a heater coil chamber formed by a heater coil housing;

the heater coil housing having a base and a pair of sidewalls;

an air inlet in the base;

first and second notches between the pair of sidewalls;

a heater coil wrapped around a wick;

the wick extending through the notches into a recessed pocket between the heater coil housing and a media storage tank wall;

the wick perpendicular to the longitudinal axis of the cartomizer;

electrical contacts extending through the base and connected to the heater coil;

the heater coil housing having an outlet connected to an axial cylindrical neck;

an inner tube inserted into the axial cylindrical neck;

the inner tube inserted to a proximal seal;

an expansion chamber between the proximal seal and a mouth piece;

two absorbent material pieces in the expansion chamber;

the mouthpiece having one or more outlets; and

the mouthpiece attached to the cartomizer via a snap fit.

14. The cartomizer of claim 13 wherein a first end of the cartomizer is adapted to be inserted into a battery assembly.

15. The cartomizer of claim 13 wherein portions of the wick are compressed by ports in the heater coil housing having an opening less than a diameter of the wick.

16. The cartomizer of claim 13 wherein the recessed pocket is configured to retain liquid by surface tension.

17. The cartomizer of claim 13 further comprising a cover on the first end of the cartomizer to protect connectors on the cartomizer.

18. The cartomizer of claim 13 wherein the absorbent material is a porous material 0.1-6 mm thick.

19. The cartomizer of claim 13 wherein the absorbent material comprises cotton.

20. The cartomizer of claim 13 wherein the absorbent material comprises a porous plastic material.

21. The cartomizer of claim 13 wherein the inner tube and the heater coil housing are connected by an interference fit.

22. The cartomizer of claim 13 having two air inlets.

23. A cartomizer for use with an electronic smoking device, comprising:

a liquid media storage tank;

a heater coil chamber formed by a heater coil housing;

the heater coil housing having a base and a pair of sidewalls;

an air inlet in the base;

first and second notches between the pair of sidewalls;

a heater coil wrapped around a wick;

the wick extending through the notches into a recessed pocket between the heater coil housing and a media storage tank wall;

the wick perpendicular to the longitudinal axis of the cartomizer;

electrical contacts extending through the base and connected to the heater coil;

the heater coil housing having an outlet connected to an axial cylindrical neck;

an inner tube inserted into the axial cylindrical neck of the heater coil housing;

the inner tube connected to the heater coil housing by an interference fit;

the inner tube inserted to a proximal seal;

an expansion chamber between the proximal seal and a mouth piece;

an absorbent material in the expansion chamber, the absorbent material comprising a porous material 0.1-6 mm thick;

the mouthpiece having one or more outlets;

the mouthpiece attached to the cartomizer via a snap fit; and

a cover on the first end of the cartomizer to protect connectors on the cartomizer.

24. The cartomizer of claim 23 wherein a first end of the cartomizer is adapted to be inserted into a battery assembly.

25. The cartomizer of claim 24 wherein the first end of the cartomizer is adapted to connect to a battery assembly via a friction fit.

26. The cartomizer of claim 23 wherein portions of the wick are compressed by ports in the heater coil housing, the ports having an opening less than a diameter of the wick.

27. The cartomizer of claim 23 wherein the recessed pocket is configured to retain liquid by surface tension.

28. The cartomizer of claim 23 wherein the mouth piece is attached to the liquid storage tank with a snap fit.

29. The cartomizer of claim 23 having two air inlets.

30. The cartomizer of claim 23 wherein the porous material comprises cotton.
