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.

First claim

The invention claimed is:

1. A vaporizing device, comprising:
a first housing removably attached to a second housing;
a battery in the first housing electrically connected to a control circuit;
a charging connector on the first housing for charging the battery;
an LED on the first housing, and a switch, electrically connected to the control circuit;
at least one air inlet for allowing air into the second housing;
a spiral metal wire inside of the second housing, with the spiral metal wire in contact with a cylindrical fiber material component;
the second housing having a liquid storage container containing a liquid;
a passageway in the second housing, with liquid moving liquid from the liquid storage container through the passageway onto the spiral metal wire, to create vapor;
the first and second housing together forming an elongated vaporizing device having a longitudinal axis.

2. The vaporizing device of claim 1 comprising a single spiral metal wire.

3. The vaporizing device of claim 1 wherein a longitudinal axis of the battery is parallel to the longitudinal axis of the device.

4. The vaporizing device of claim 2 with the wire coil around an outside surface of the cylindrical fiber material component.

5. The vaporizing device of claim 3 further comprising a passage tube in the second housing on one side of the liquid storage container.

6. The vaporizing device of claim 1 further comprising a switch electrically connected to the control circuit.

7. The vaporizing device of claim 6 with the nicotine comprising 0.1% to 6% of the liquid.

8. The vaporizing device of claim 7 with the liquid further including glycerol or propylene glycol.

9. A vaporizing device, comprising:
a first housing attachable to and detachable from a second housing, the first and second housings forming an elongated device;
a battery in the first housing electrically connected to a control circuit;
a charging connector on the first housing for charging the battery;
an LED on the first housing, and a switch, electrically connected to the control circuit;
at least one air inlet for allowing air to flow into the second housing;
wire coil heating element inside of the second housing, the wire coil heating element electrically connected to the control circuit, and with the wire coil heating element in contact with a fiber material;
the second housing having a liquid storage container containing a liquid; and
a passageway in the second housing for moving liquid from the liquid storage container onto the wire coil heating element, to create vapor.

10. The vaporizing device of claim 9 with the wire coil heating element around an outside surface of the fiber material.

11. The vaporizing device of claim 9 further comprising a passage tube in the second housing on one side of the liquid storage container.

12. The vaporizing device of claim 9 having a single wire coil heating element.

13. The vaporizing device of claim 9 further comprising a sensor electrically connected to the control circuit.

14. The vaporizing device of claim 9 further comprising a switch electrically connected to the control circuit .

15. The vaporizing device of claim 11 with the liquid storage container.

16. The vaporizing device of claim 9 wherein a longitudinal axis of the battery is parallel to a longitudinal axis of the device.

17. A vaporizing device, comprising:
a first housing attached to a second housing, with the first and second housings on a longitudinal axis of the device;
a battery in the first housing electrically connected to a control circuit;
a charging connector in the first housing for charging the battery;
an LED in the first housing;
at least one air inlet for allowing air to flow into the second housing;
a wire coil heating element inside of the second housing, the wire coil heating element electrically connected to the control circuit, and with the wire coil heating element in contact with a fiber material;
the second housing having a polymer material liquid storage container for containing a liquid comprising nicotine, and glycerol or propylene glycol;
a passage tube in the second housing on one side of the polymer material liquid storage container; and
a passageway in the second housing for moving liquid from the polymer material liquid storage container onto the wire coil heating element, to create vapor by heating the wire coil heating element.

18. The vaporizing device of claim 17 further comprising a switch electrically connected to the control circuit.

19. The vaporizing device of claim 9 wherein a longitudinal axis of the battery is parallel to a longitudinal axis of the device.

20. The vaporizing device of claim 17 wherein a longitudinal axis of the battery is parallel to the longitudinal axis of the device.
