Claims (31)

1. An electronic cigarette, comprising:

a housing having an inlet and an outlet;

a battery and an atomizer in the housing, with the atomizer including a tube having a metal wire heater coil within the tube electrically linked to the battery;

a liquid source in the housing and outside of the tube;

with liquid in the liquid source capable of moving from the liquid source into the tube and contacting the wire heater coil to create vapor.

2. The electronic cigarette of claim 1 with the tube comprising a fiber material.

3. The electronic cigarette of claim 1 wherein the wire heating coil is in contact with the tube.

4. The electronic cigarette of claim 1 further comprising a base attached to the tube.

5. The electronic cigarette of claim 4 further comprising screw threads on the base.

6. The electronic cigarette of claim 1 with the tube having an inner diameter of .05 to 2 mm.

7. The electronic cigarette of claim 6 with the tube having a length of 3-20 mm.

8. The electronic cigarette of claim 1 with an unobstructed flow path between the tube and the outlet.

9. The electronic cigarette of claim 1 with the housing having a first section attached to a second section.

10. The electronic cigarette of claim 9 with the inlet in the first section and the outlet in the second section.

11. The electronic cigarette of claim 9 with the battery in the first section and the atomizer and the liquid source in the second section.

12. An electronic cigarette, comprising:

a housing having an inlet and an outlet;

a battery and an atomizer in the housing including a vaporization tube, a wire heater coil within the vaporization tube electrically connectable to the battery, and with the vaporization tube having a first end connected to receive liquid from a liquid source outside of the vaporization tube, and a second open end to allow vapor, formed within the vaporization tube from liquid from the liquid source, to flow out of the vaporization tube of the atomizer, and out of the outlet of the housing; and

with a longitudinal axis of the wire heater coil substantially parallel to a longitudinal axis of the vaporization tube.

13. The electronic cigarette of claim 12 with liquid from the liquid source moving into direct contact with the wire heater coil in the vaporization tube.

14. The electronic cigarette of claim 12 wherein a central section of the heating coil is in contact with the vaporization tube.

15. The electronic cigarette of claim 12 with an unobstructed flow path between the second open end of the vaporization tube and the outlet of the housing.

16. The electronic cigarette of claim 12 with the vaporization tube comprising a fiber material and the wire heater coil comprising metal.

17. An electronic cigarette comprising:

a housing, an air inlet leading into the housing, and an air outlet leading out of the housing;

a battery, a control circuit, a sensor, and a vaporization nozzle in the housing, with the control circuit electrically connected to the battery and to the sensor;

the vaporization nozzle including a coil heating element within a tube and with the coil heating element electrically connected to the control circuit; and

a solution storage in the housing outside of the tube, wherein solution in the solution storage is capable of moving from the solution storage into the tube.

18. The electronic cigarette of claim 17 wherein a central section of the heating coil is in contact with the vaporization nozzle.

19. The electronic cigarette of claim 17 with an unobstructed flow path between the vaporization nozzle and the air outlet.

20. The electronic cigarette of claim 17 with the vaporization nozzle comprising a fiber material and the wire heater coil comprising metal.
