Abstract

An electronic cigarette ( 10 ) includes an atomizer ( 26 ) having a coil-less heating element ( 4 ) with a heating section ( 6 ) connected to an electrical power source and two end sections in contact with a liquid supply ( 34 ). The heating element ( 4 ) is made of one or more woven fiber tubes ( 2 ) having a hollow interior such that the liquid can be transported from the liquid supply ( 34 ) to the heating section ( 6 ) through the hollow interior along the woven fiber tubes ( 2 ) or through the fiber materials via capillary action.

Claims (24)

1. An electronic smoking device comprising:

a housing;

one or more woven fiber tubes in the housing; and

a liquid supply in the housing, wherein:

at least one of the woven fiber tubes comprises an electrically conductive heating section and one or more end sections;

a first side of the heating section is connected to a first lead;

a second side of the heating section is connected to a second lead;

the first and second leads are connectable to an electrical power source; and

one or more end sections of the woven fiber tube are in contact with the liquid supply.

2. The device of claim 1 , wherein the entire woven fiber tube is electrically conductive.

3. The device of claim 1 , wherein the woven fiber tube comprises carbon fibers, nickel-chromium, steel, titanium, iron-chromium-aluminum, molybdenum disilicide, silicon carbide, silicon dioxide, Dacron, ceramic fibers, or a combination thereof.

4. The device of claim 1 , wherein the woven fiber tube has a hollow interior.

5. The device of claim 1 , wherein the woven fiber tube has a first end joined to the first side of the heating section and a second end joined to the second side of the heating section, and wherein the first and second ends of the woven fiber tube extend into the liquid supply.

6. The device of claim 1 , wherein the woven fiber tube is U-shaped, L-shaped, or C-shaped.

7. The device of claim 1 , wherein the heating section is straight and the end sections are longer than the heating section.

8. The device of claim 1 , wherein the end sections of the woven fiber tube are perpendicular to the heating section of the woven fiber tube.

9. The device of claim 1 , wherein the device comprises two or more woven fiber tubes.

10. The device of claim 9 , wherein the two or more woven fiber tubes have different diameters.

11. The device of claim 9 , wherein the two or more woven fiber tubes are positioned in parallel to each other.

12. The device of claim 9 , wherein the two or more woven tubes are positioned in direct contact of each other.

13. The device of claim 1 , wherein the heating section of the woven fiber tube has a different diameter from the end sections of the woven fiber tube.

14. The device of claim 1 , wherein the liquid supply contains free-flowing liquid.

15. The device of claim 1 , wherein the liquid supply comprises a porous medium that stores liquid.

16. The device of claim 1 , wherein the one or more woven fiber tubes comprise multiple woven fiber tubes with different diameters.
