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 of the present invention 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 electronic smoking device component, comprising:

a housing having a first end and a second end;

a heating element in the housing;

at least one air opening leading into the housing, with the heating element in between the air opening and the second end of the housing;

a liquid supply in the housing for supplying liquid onto the heating element; and

a connection device at a first end of the housing.

2. The electronic smoking device component of claim 1 wherein the connection device comprises screw threads.

3. The electronic smoking device component of claim 1 with the liquid supply comprising a container and further including a refill opening on the housing leading into the container.

4. The electronic smoking device component of claim 1 further including a control circuit in the housing electrically connected to the heating element.

5. The electronic smoking device component of claim 4 further including a switch on the housing electrically connected to the control circuit.

6. The electronic smoking device component of claim 1 further including a switch on the housing electrically connected to the heating element.

7. The electronic smoking device component of claim 1 further including a mouthpiece on a second end of the housing.

8. The electronic smoking device component of claim 1 with the heating element comprising a wire coil.

9. The electronic smoking device component of claim 8 further including a baffle plate between the liquid supply and the wire coil.

10. The electronic smoking device component of claim 1 with the connection device adapted to connect to a battery component.

11. The electronic smoking device component of claim 1 further including a valve in the housing for controlling flow of liquid from the liquid supply to the heating element.

12. The electronic smoking device component of claim 1 further including an air flow sensor in the housing.

13. The electronic smoking device component of claim 12 further including a control circuit in the housing electrically connected to the air flow sensor and to the heating element.

14. The electronic smoking device component of claim 8 with the wire coil within a vaporization nozzle.

15. A component for an electronic atomizing cigarette, comprising:

a tubular housing;

screw threads at a first end of the tubular housing;

a mouthpiece at a second end of the tubular housing;

a wire coil heating element in the housing; and

a liquid supply in the housing for supplying liquid to the wire coil.

16. The component of claim 15 further including a control circuit in the housing electrically connected to the heating element and to an air flow sensor in the housing.

17. The component of claim 15 with the wire coil inside of a tube parallel to the tubular housing.

18. The component of claim 15 further including one or more air holes in the housing.

19. The component of claim 15 further including a switch on the housing electrically connected to the heating element.
