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 (55)

1. A vaporizing device, comprising:

a rechargeable battery in a housing, the rechargeable battery electrically connected to a control circuit;

a charging connector in the housing for charging the rechargeable battery;

an LED in the housing electrically connected to the control circuit;

at least one air inlet for allowing air to flow into the housing;

a wire coil heating element inside of the housing, the wire coil heating element electrically connected to the control circuit, and with the wire coil heating element having a length aligned along and in contact with a length of fiber material;

a liquid storage container holding a liquid movable into contact with the fiber material;

the at least one air inlet leading into an air flow path in the housing to an outlet on the housing, with the length of fiber material in the air flow path; and

the wire coil heating element vaporizing liquid from the liquid storage container.

2. The vaporizing device of claim 1 further including an air flow sensor positioned to sense air flow in the air flow path, with the air flow sensor electrically connected to the control circuit.

3. The vaporizing device of claim 1 further including a switch electrically connected to the control circuit for switching on the wire coil heating element.

4. The vaporizing device of claim 1 with the charging connector at a first end of the housing.

5. The vaporizing device of claim 1 wherein the wire coil heating element is wrapped around the length of fiber material.

6. The vaporizing device of claim 1 wherein the fiber material comprises glass fiber.

7. The vaporizing device of claim 1 further comprising a passageway providing liquid to the length of the fiber material.

8. The vaporizing device of claim 1 wherein the length of fiber material is longer than the wire coil heating element.

9. The vaporizing device of claim 1 with the length of fiber material in between the rechargeable battery and an outlet on a mouthpiece.

10. The vaporizing device of claim 1 wherein the length of fiber material has a free end.

11. The vaporizing device of claim 1 with the length of fiber material supported on a base and further including an electrode lead adjacent to the base and electrically connected to the wire coil heating element.

12. The electronic vaporizing device of claim 2 with the control circuit configured such that luminance of the LED changes based on an output of the air flow sensor.

13. The electronic vaporizing device of claim 2 with the control circuit configured to control luminance of the LED when the air flow sensor senses airflow, such that the LED simulates the appearance of a conventional burning cigarette tip.

14. The electronic vaporizing device of claim 1 with the housing having a first section attached to a second section, and with the rechargeable battery in the first section.

15. A vaporizing device, comprising:

a first housing attachable to and detachable from a second housing;

a rechargeable battery in the first housing electrically connected to a control circuit;

the first housing having an LED electrically connected to the control circuit;

at least one air inlet for allowing air to flow into the second housing;

a heating element comprising a wire coil inside of the second housing, the heating element electrically connected to the control circuit, and with the heating element contacting a fiber material;

the second housing containing a liquid movable into contact with the fiber material;

the at least one air inlet connecting into an air flow path in the second housing leading to an outlet on the second housing; and

the heating element vaporizing the liquid.

16. The vaporizing device of claim 15 further including an air flow sensor electrically connected to the control circuit.

17. The vaporizing device of claim 15 further including a switch electrically connected to the control circuit for switching on the wire coil.

18. The vaporizing device of claim 15 with the liquid in a liquid container in the second housing.

19. The vaporizing device of claim 15 wherein the wire coil is wrapped around the fiber material.

20. The vaporizing device of claim 19 wherein the fiber material comprises glass fiber.

21. The vaporizing device of claim 15 further comprising a passageway providing liquid to the fiber material.

22. The vaporizing device of claim 15 with the fiber material in between the rechargeable battery and an outlet on a mouthpiece.

23. The vaporizing device of claim 15 with the fiber material having a free end.

24. The vaporizing device of claim 15 with the fiber material supported on a base and further including an electrode lead adjacent to the base and electrically connected to the wire coil.

25. A vaporizing device, comprising:

a first housing attachable to and detachable from a second housing;

a rechargeable battery in the first housing electrically connected to a control circuit;

a charging connector in the first housing electrically connected to the rechargeable battery;

the first housing having an LED electrically connected to the control circuit;

at least one air inlet for allowing air to flow into the second housing;

a wire coil inside of the second housing, the wire coil electrically connected to the control circuit, and the wire coil wound around and contacting a fiber material, the fiber material longer than the wire coil;

the second housing containing a liquid movable into contact with the fiber material;

the at least one air inlet connecting into an air flow path in the second housing leading to an outlet in a mouthpiece on the second housing;

the fiber material in between the rechargeable battery and the outlet;

an air flow sensor positioned to sense air flow in the air flow path, with the air flow sensor electrically connected to the control circuit; and

the wire coil vaporizing the liquid.

26. The vaporizing device of claim 25 with the fiber material having a free end.

27. The vaporizing device of claim 25 with the fiber material supported on a base and further including an electrode lead adjacent to the base and electrically connected to the wire coil.
