Abstract

An electronic cigarette comprises nicotine without harmful tar. The cigarette includes a shell, a cell, nicotine solution, control circuit, and an electro-thermal vaporization nozzle installed in the air suction end of the shell. The advantages are smoking without tar, reducing the risk of cancer, the user still gets a smoking experience, the cigarette is not lit, and there is no fire danger.

Claims

1. An atomizer for an electronic cigarette, comprising:

an enclosure;

a wire heater coil within the enclosure;

the enclosure having an inlet; and

the enclosure having an outlet to allow vapor, formed within the enclosure by liquid contacting the wire heater coil, to flow out of the enclosure.

2. The atomizer of claim 1 with the enclosure comprising a fiber material.

3. The atomizer of claim 1 with the inlet at one end of the enclosure and the outlet at an opposite end of the enclosure

4. The atomizer of claim 1 with the enclosure comprising a substantially cylindrical tube.

5. The atomizer of claim 1 further comprising a base attached to the enclosure.

6. The atomizer of claim 5 with the inlet at least partially in the base.

7. The atomizer of claim 5 wherein the base is cylindrical.

8. The atomizer of claim 7 with the inlet extending through the cylindrical base.

9. The atomizer of claim 5 further comprising screw threads on the base.

10. The atomizer of claim 4 with the tube having an inner diameter of 0.05 to 2 mm.

11. The atomizer of claim 4 with the tube having a length of 3-20 mm.

12. The atomizer of claim 1 further comprising a liquid tube connecting into the inlet, for providing liquid into the enclosure.

13. An atomizer for an electronic cigarette, comprising:

a tube having a liquid inlet;

a wire heater coil within the tube;

the tube having a vapor outlet to allow vapor, formed within the enclosure by liquid contacting the wire heater coil, to flow out of the tube.

14. The atomizer of claim 13 with the tube comprising a fiber material.

15. The atomizer of claim 13 with the liquid inlet at a first end of the tube and with the vapor outlet comprising an opening at a second end of the tube.

16. The atomizer of claim 13 with a longitudinal axis of the wire heater coil substantially parallel to a longitudinal axis of the tube.

17. The atomizer of claim 13 further comprising a base attached to the tube, with the liquid inlet extending through the base.
