Abstract

An electronic cigarette includes a battery assembly and an atomizer assembly within a housing with the battery assembly electrically connected to the atomizer assembly. The housing has one or more air inlets. A liquid storage component is in contact with a porous component of the atomizer assembly, with the porous component having a run-through hole. A heating wire is in an air flow path through the run-through hole.

Claims (28)

1. A electronic vaporizing device, comprising:

a battery and a liquid storage component in an elongated cylindrical housing having at least one air inlet and an outlet;

a hollow cylindrical component comprising a fiber material, with the hollow cylindrical component in the elongated cylindrical housing and having a central axis parallel to a longitudinal axis of the elongated cylindrical housing, with the hollow cylindrical component in contact with the liquid storage component, and an atomizing chamber formed within inner cylindrical walls of the hollow cylindrical component between a front end opening and a back end opening of the hollow cylindrical component, to allow air to flow into the atomizing chamber from the front end opening and out from the back end opening of the hollow cylindrical component;

an air flow path from the one or more air inlets through the atomizing chamber in the hollow cylindrical component, to the outlet; and

a wire coil in the atomizing chamber wound on a porous component and electrically connected to the battery.

2. The device of claim 1 further including a restriction component in the air flow path having a restriction hole concentric with the front end opening of the hollow cylindrical component.

3. The device of claim 1 further including a plate fixed in place in the elongated cylindrical housing at the front end opening of the hollow cylindrical component, with the plate in contact with the hollow cylindrical component.

4. The device of claim 3 with the wire coil having first and second wire leads passing out of the front end opening of the hollow cylindrical component, and with the first and second wire leads extending through the plate, for connecting the wire coil to the battery.

5. The device of claim 3 with the atomizing chamber having a uniform diameter along the length of the atomizing chamber, and the plate having a diameter larger than the diameter of the atomizing chamber.

6. The device of claim 1 with the front end opening and the back end opening of the hollow cylindrical component having equal diameters.

7. The device of claim 1 with the hollow cylindrical component having a single front end opening.

8. The device of claim 1 with the liquid storage component at a position in the elongated cylindrical housing between the outlet and the hollow cylindrical component.

9. The device of claim 1 further including a restriction component between the hollow cylindrical component and the at least one inlet, with the restriction component having a restriction hole smaller than the front end opening of the hollow cylindrical component.

10. The device of claim 1 with the hollow cylindrical component having an outer cylindrical sidewall having a first diameter, and with the wire coil having an outer diameter less than the first diameter.

11. The device of claim 10 with the atomizing chamber parallel to the longitudinal axis.

12. The device of claim 11 with the wire coil including first and second wire leads passing out of the front end opening of the porous component.

13. The device of claim 12 further comprising a frame including a first section having a first diameter and a second section having a second diameter less than the first diameter, and with second section inserted into the front end opening of the hollow cylindrical component.

14. A vaporizing device, comprising:

a battery assembly and an atomizer assembly within an elongated cylindrical housing with the battery assembly electrically connected to the atomizer assembly;

a liquid storage component in the elongated cylindrical housing;

with the elongated cylindrical housing having one or more air inlets;

the atomizer assembly including an atomization chamber having a front end opening and a back end opening to allow air to flow into the atomization chamber from the front end opening and out from the back end opening; and

a heating wire coil wound on a porous component that is perpendicular to a longitudinal axis of the elongated cylindrical housing, with the heating wire coil in an air flow path between the front end opening and the back end opening of the atomization chamber.

15. The device of claim 14 with the atomization chamber having a uniform diameter along the length of the atomization chamber.

16. The device of claim 14 with the heating wire coil having an outer diameter less than an inner diameter of the atomizing chamber.

17. The device of claim 14 further comprising a check valve between the inlet and the porous component.

18. The device of claim 14 further including a restriction component between the hollow cylindrical component and the at least one air inlet, with the restriction component having a restriction hole smaller than the open front end of the hollow cylindrical component.

19. The device of claim 14 further including a plate fixed in place in the tubular housing, with the plate in contact with the front end of the hollow cylindrical component, and the atomization chamber having a uniform diameter along the length of the atomization chamber, and the plate having a diameter larger than the uniform diameter of the atomization chamber.
