Abstract

An electronic cigarette including a liquid supply, an air inlet, an inhalation port, and an atomizer. The liquid supply has a housing with a spiral container, having an outlet for directing a liquid held within the container out to the atomizer and at least one inlet sealed by a sealing agent to impede movement of the liquid. An air channel leads from the air inlet through the atomizer to the inhalation port for directing an aerosol generated at the atomizer to the inhalation port.

Claims (29)

1. An electronic smoking device comprising:

a liquid container containing a liquid;

an outlet at a second end of the liquid container;

a sealing agent in the liquid container, the liquid between the sealing agent and the outlet, and the sealing agent movable within the liquid container; and

an atomizer positioned to receive liquid from the outlet of the liquid container; and

wherein the sealing agent moves through the liquid container by capillary action as the liquid is consumed during use of the electronic smoking device; and wherein the liquid container is spiral container.

2. The electronic smoking device of claim 1 further including an air channel extending centrally through spiral liquid container with the spiral container winding around the air channel.

3. The electronic smoking device of claim 1 with the liquid container and the atomizer in a housing, and with the liquid container removable from the housing.

4. The electronic smoking device of claim 1 wherein the liquid container is a spiral liquid container positioned between an internal wall of a housing and an external wall of the housing.

5. The electronic smoking device of claim 4 further including a filler material or a sealant in a space between the spiral liquid container and the external wall of the liquid container.

6. The electronic smoking device of claim 4 with the spiral liquid container having an inlet at a first end of the housing, and the outlet of the spiral liquid container is at a second end of the spiral liquid container, opposite from the first end of the housing.

7. The electronic smoking device of claim 4 wherein the inlet of the spiral liquid container is at a first end of the housing, and the outlet of the spiral liquid container is on a surface of an air channel extending through the spiral liquid container.

8. The electronic smoking device of claim 1 with the atomizer having a heating element in contact with the liquid guiding structure.

9. The electronic smoking device of claim 1 wherein the sealing agent comprises grease.

10. The electronic smoking device of claim 9 wherein the grease comprises a lithium based grease having a viscosity of about 4200˜4600 cs at 25 degrees Celsius.

11. An electronic smoking device comprising:

a housing having an air channel extending from air inlet to an inhalation port;

an atomizer and a liquid supply in the housing, the liquid supply comprising a spiral container including a first compartment and a second compartment, with each compartment having an inlet and an outlet, the outlets connecting into the air channel; and

each inlet is sealed by a sealing agent movable via capillary action.

12. An electronic smoking device comprising

a housing;

an air channel in the housing connecting an air inlet to an inhalation port;

an atomizer and a liquid supply in the housing, wherein the liquid supply comprises a liquid supply housing containing two spiral containers separated by a partition wall, with each spiral container containing a liquid;

wherein each spiral container has an inlet and an outlet and each inlet is sealed by a sealing agent movable through the spiral container, the sealing agent having a viscosity higher than the liquid.

13. The electronic smoking device of claim 12 wherein the spiral containers are parallel to each other.

14. The electronic smoking device of claim 12 wherein the liquid supply includes a liquid supply housing, and the inlets of each of the spiral containers are at a first end of the liquid supply housing, and the outlets of the spiral containers at a second end of the liquid supply housing opposite from the first end of the liquid supply housing.

15. The electronic smoking device of claim 12 wherein the liquid supply includes a liquid supply housing, the inlets of the spiral containers at a first end of the liquid supply housing, and the outlets of the spiral containers are on a surface of the air channel.

16. The electronic smoking device of claim 12 wherein the spiral containers wind around the air channel.

17. The electronic smoking device of claim 12 wherein the sealing agent is lithium based grease having a viscosity of about 2800˜3400 cs at 25 degrees Celsius.
