Device for storing and vaporizing liquid media
A device for storing and vaporizing liquid media can comprise an annular liquid media storage tank and a heater configured to vaporize liquid stored in the annular liquid media storage tank.
1. A vaporizing device comprising:
an outer tube mounted around at least a portion of an inner tube, the outer tube having an outer surface and an inner surface;
the inner tube having an inner surface and an outer surface, the inner surface of the inner tube forming an air path;
an annular liquid storage tank between the outer surface of the inner tube and the inner surface of the outer tube;
a mouthpiece connected to a first end of the inner tube;
a heater coil chamber in a heater coil casing;
a heater coil mounted at least partially within the heater coil casing;
a wick extending through a center of the heater coil and through a first port in a first wall of the heater coil casing and through a second port in a second wall of the heater coil casing; and
a first end portion of the wick extending into a first individual recessed pocket in the annular liquid storage tank, and a second end portion of the wick extending into a second individual recessed pocket in the annular liquid storage tank.
2. The device of claim 1 wherein the heater coil chamber comprises an upper heater coil housing having a housing air outlet connected with a distal end of the inner tube and a lower heater coil housing having a housing air inlet.
3. The device of claim 2 wherein the heater coil is mounted at least partially within the heater coil casing between the housing air outlet and the housing air inlet.
4. The device of claim 1 wherein the first and second individual recessed pockets are formed by an outer surface of the heater coil casing and the inner surface of the outer tube.
5. The device of claim 1 wherein the first port and the second port are diametrically opposed to one another.
6. The device of claim 1 wherein the first individual recessed pocket and the second individual recessed pocket extend distally.
7. The device of claim 1 wherein a distal end of the outer tube is connected with a battery connector.
8. The device of claim 7 wherein the battery connector comprises an annular outer surface that connects with the inner surface of the outer tube.
9. The device of claim 7 further including an annular insulator grommet inserted into an axial cylindrical opening of the battery connector, and a center battery connector inserted into an axial cylindrical opening of the insulator grommet.
10. The device of claim 9 wherein the center battery connector comprises an axial cylindrical opening through the center battery connector which connects into the inner surface of the inner tube.
11. The device of claim 1 wherein the inner surface of the inner tube has a frustoconical shape.
12. A cartomizer for an electronic cigarette, comprising:
an outer tube around at least a portion of an inner tube;
the inner tube having an inner surface and an outer surface, the inner surface of the inner tube forming an air path;
an annular liquid storage tank between the outer surface of the inner tube and an inner surface of the outer tube;
a mouthpiece at a first end of the inner tube;
a heater coil chamber in a heater coil casing;
a heater coil mounted at least partially within the heater coil casing;
a wick extending through a center of the heater coil and through a first port in the heater coil casing and through a second port in the heater coil casing; and
a first end of the wick extending into a first recessed pocket in the annular liquid storage tank, and a second end of the wick extending into a second recessed pocket in the annular liquid storage tank.
13. The cartomizer of claim 12 wherein an outer surface of the heater coil casing adjacent to the ports is recessed to form the first recessed pocket and second recessed pocket, and the first recessed pocket and second recessed pocket are located on opposite sides of the heater coil casing.
14. The cartomizer of claim 13 wherein the first recessed pocket and the second recessed pocket are holes in the heater coil casing that have a diameter greater than a diameter of the ports.
15. The cartomizer of claim 12 wherein the inner tube is a rigid tube permanently supported at the first end of the inner tube and at the second end of the inner tube.
16. The cartomizer of claim 12 further comprising an absorbent material between the first end of the inner tube and the mouthpiece, with a gap between the first end of the inner tube and the absorbent material.
