Abstract

An aerosol delivery device or electronic cigarette generates an aerosol or vapor for consumption by a consumer. The device may include a cartridge holding an aerosol precursor substance or fluid that is turned into the aerosol or vapor. The fluid may be stored in reservoir that allows for the fluid to be passed to an atomizer for generating the aerosol. The reservoir may be a flexible bladder that equalizes pressure inside the cartridge to reduce leakage, such as with an internal valve to activate fluid transfer. Alternatively, the reservoir may include one or more capsules that can be broken or melted to release the fluid.

First claim

We claim:

1. An electronic cigarette comprising:
a mouthpiece configured to receive air with vapor;
a flexible bladder storing a fluid and configured to prevent excess air in the flexible bladder by changing shape as the fluid is moved;
an outside member configured to support the flexible bladder; and
an atomizer configured to receive at least a portion of the fluid that is moved from the flexible bladder, wherein the atomizer is configured to generate the vapor by heating the moved fluid.

2. The electronic cigarette of claim 1 further comprising:
a porous material coupled with the flexible bladder for moving the fluid from the flexible bladder.

3. The electronic cigarette of claim 2 wherein the porous material comprises a wick configured to receive the fluid.

4. The electronic cigarette of claim 3 wherein the atomizer further comprises a heating element configured to heat the fluid from the wick.

5. The electronic cigarette of claim 4 wherein the heating element comprises a heating wire wrapped around the wick.

6. The electronic cigarette of claim 4 further comprising a battery configured to provide power to the heating element.

7. The electronic cigarette of claim 2 wherein the porous material cap comprises a porous ceramic material.

8. The electronic cigarette of claim 7 wherein the porous material comprises a cap configured for sealing the flexible bladder.

9. The electronic cigarette of claim 8 wherein the cap seals the flexible bladder by creating a compression fit of the flexible bladder.

10. The electronic cigarette of claim 1 wherein the flexible bladder changing shape comprises the flexible bladder collapsing.

11. The electronic cigarette of claim 1 wherein the flexible bladder comprises a latex or thin plastic.

12. The electronic cigarette of claim 1 wherein the outside member comprises a cylindrical tube configured to hold the flexible bladder.

13. An aerosol delivery device comprising:
a storage of an aerosol precursor substance;
a moveable structure configured to move relative to the storage to cause a distribution of the aerosol precursor substance; and
a vaporizer configured to receive the aerosol precursor substance after the distribution, wherein the vaporizer generates an aerosol by vaporizing the aerosol precursor substance.

14. The aerosol delivery device of claim 13 further comprising:
a wick configured to transport the distributed aerosol precursor substance; and
a heating element adjacent the wick configured to heat the distributed aerosol precursor substance as part of the vaporizing.

15. The aerosol delivery device of claim 13 wherein the storage comprises one or more capsules.

16. The aerosol delivery device of claim 15 wherein the movement relative the container comprises the moveable structure breaking the one or more capsules to release the aerosol precursor substance.

17. The aerosol delivery device of claim 15 wherein the moveable structure comprises the heating element that is configured to melt at least a portion of the one or more capsules.

18. The aerosol delivery device of claim 15 wherein the capsules are stored and released near the heating element and the wick.

19. A vaporization device comprising:
a battery portion; and
a cartridge configured to receive power from the battery portion and to store a fluid, the cartridge comprising:
a container configured to hold the fluid;
an moveable component coupled with the container that is configured to cause a transfer of at least a portion of the fluid from the container; and
a heating element configured to generate vapor from the fluid.

20. The vaporization device of claim 19 , wherein the container comprises a flexible bladder that equalizes a pressure inside the flexible bladder to control leakage caused by pressure changes, wherein the equalization of pressure is due to a shape of the flexible bladder collapsing as the fluid is removed.
