Abstract

Handheld vaporizing devices with improved heating element and temperature controls, improved e-liquid reservoir, and capacitive technology to activate the heating element to prime the device to deliver aerosol on demand.

Claims

1. A handheld electronic vaporizing device, comprising:

a body defining a cavity;

a mouthpiece connected to said body;

an electroconductive textile heating element;

an elastically deformable reservoir;

a power element;

a power connect element;

a capacitive touch sensor element;

a light element;

a first air inlet having a first valve disposed on the external wall of said body;

a second air inlet having a second valve disposed on one end of said mouthpiece; and

an air outlet disposed on a second opposite end of said mouthpiece,

wherein the heating element, the reservoir, the power element and the power connect element are disposed inside the body cavity and are sequentially arranged and interconnected.

2. A handheld electronic vaporizing device according to claim 1, wherein said elastically deformable reservoir is formed from a material selected from the group consisting of polymers and metal/polymer composites.

3. A handheld electronic vaporizing device according to claim 2, wherein said elastically deformable reservoir comprises polyester with aluminum printed exterior.

4. A handheld electronic vaporizing device according to claim 1, wherein said electroconductive textile heating element includes a fabric selected from the group consisting of fabric with metalized coating, fabric with electro-conductive coating, and fabric incorporating woven metal strands.

5. A handheld electronic vaporizing device according to claim 4, wherein said electroconductive textile heating element comprises ultra thin grade stainless steel wire cloth.

6. A handheld electronic vaporizing device according to claim 1, wherein said electroconductive textile heating element is electrically responsive to said capacitive touch sensor element.

7. A handheld electronic vaporizing device according to claim 1, wherein said electroconductive textile heating element is activated by a user'"'"'s touch on said capacitive touch sensor element.

8. A handheld electronic vaporizing device according to claim 1, wherein said electroconductive textile heating element is regulated to heat a volatile e-liquid to a pre-set temperature.

9. A handheld electronic vaporizing device according to claim 8, wherein said pre-set temperature is the temperature of optimal vaporization of said volatile e-liquid.

10. A handheld electronic vaporizing device according to claim 1, wherein said capacitive touch sensor element regulates duty cycles of said electroconductive textile heating element.

11. A handheld electronic vaporizing device according to claim 1, wherein said light element comprises an LED light.
