Abstract

An electronic vaporizing device has an air flow tube passing through a liquid storage chamber ( 210 ). The air flow tube has a plurality of micro-openings ( 122 ). A thin film heating element ( 121 ) is provided on an inner wall of the air flow tube. A plurality of micro-openings in the thin film heating element ( 121 ) are aligned with the plurality of micro-openings in the airflow tube to provide a flow of liquid from the liquid storage chamber ( 210 ) to the thin film heating element ( 121 ).

First claim

The invention claimed is:

1. An electronic vaporizing device, comprising:
an airflow tube having a first section in a liquid storage chamber;
a heating element on an inner surface of the first section of the airflow tube;
a plurality of first micro-openings in the first section of the airflow tube extending radially in a straight line from the liquid storage chamber to the heating element to allow liquid to move from the liquid storage chamber to the heating element; and
a battery electrically connected to the heating element.

2. The electronic vaporizing device of claim 1 wherein the heating element comprises a hollow cylindrical porous material.

3. The electronic vaporizing device of claim 1 wherein the heating element has a plurality of second micro-openings and the liquid moves through the plurality of first micro-openings and into the plurality of second micro-openings.

4. The electronic vaporizing device of claim 1 wherein each micro-opening has an area of 0.785 μm 2 to 19.625 μm 2 .

5. The electronic vaporizing device of claim 1 wherein substantially all of the micro-openings have the same area.

6. The electronic vaporizing device of claim 1 wherein the heating element comprises an electrically conductive material and has a plurality of second micro-openings.

7. The electronic vaporizing device of claim 1 wherein the micro-openings are small enough to allow liquid to move out of the liquid storage chamber only during inhalation.

8. An electronic vaporizing device, comprising:
a first housing and a second housing;
the first housing having a first portion in a liquid storage chamber;
a heating element contacting an inner wall of the first portion of the first housing;
a plurality of first micro-openings in the first portion of the first housing, to allow liquid to move from the liquid storage chamber to the heating element, substantially each of the first micro-openings having the same area;
a plurality of second micro-openings in the heating element, the plurality of second micro-openings in the heating element adapted to receive liquid from the plurality of first micro-openings; and
a battery electrically connected to the heating element.

9. The electronic vaporizing device of claim 8 wherein the heating element is a non-porous material.

10. The electronic vaporizing device of claim 8 wherein the first and second micro-openings extend in a straight line.

11. The electronic vaporizing device of claim 8 wherein substantially each of the second micro-openings has the same area.

12. The electronic vaporizing device of claim 8 further including a plurality of third micro-openings in the liquid storage chamber positioned to provide liquid to the heating element.

13. The electronic vaporizing device of claim 8 wherein each micro-opening has an area of 0.785 μm 2 to 19.625 μm 2 .

14. The electronic vaporizing device of claim 8 wherein the heating element comprises a metal thin film heating element.

15. The electronic vaporizing device of claim 8 wherein the first housing comprises a tube extending entirely through the second housing, and the battery is in the first housing.

16. An electronic vaporizing device, comprising:
an airflow tube having a first section in a liquid storage chamber;
a heating element on an inner surface of the first section of the airflow tube;
a plurality of first micro-openings in the first section of the airflow tube extending radially from the liquid storage chamber to the heating element to allow liquid to move from the liquid storage chamber to the heating element, substantially all of the micro-openings having the same area; and
a battery electrically connected to the heating element.

17. The electronic vaporizing device of claim 16 wherein the first micro-openings extend in a straight line.
