Abstract

An electronic cigarette device having a disposable tank are described. The disposable tank may have a sealed liquid chamber, an atomizer element and a tank well. An electronic cigarette device, comprising: a housing having a power source; a disposable tank capable of holding an electronic cigarette liquid; the housing having a tank receptacle into which the disposable tank is removable attachable; and a connection mechanism that is part of the disposable tank and the tank receptacle that securely connects the disposable tank to the tank receptacle and provides power from the housing to the disposable tank.

Claims

1. An electronic cigarette device, comprising:

a housing having a power source and a tank receptacle;

a removable tank configured to be at least partially received in the tank receptacle, the removable tank comprising;

a first side extending from a top side of the removable tank to a bottom side of the removable tank;

a second side opposite the first side;

an air inlet;

a cavity capable of holding an electronic cigarette liquid and being at least partially received in the tank receptacle;

a mouthpiece that forms an air outlet, the mouthpiece formed on the top side of the removable tank, wherein the mouthpiece extends along the first side and is laterally spaced away from the second side and the cavity;

an atomizer portion located at a lower portion adjacent the bottom side of the removable tank, the atomizer portion having a tank well and a heater element; and

a mechanical connection configured to removably attach the removable tank to the tank receptacle when engaged, wherein the tank receptacle is configured to support the bottom side and the second side of the removable tank while exposing at least the mouthpiece, the air inlet and the first side of the removable tank when the removable tank is attached to the tank receptacle.

2. The device of claim 1, wherein the heater element is configured to be connected to the power source in the housing and vaporize the electronic cigarette liquid when the removable tank is attached to the tank receptacle.

3. The device of claim 1, wherein the removable tank is a closed tank.

4. The device of claim 2, wherein the vaporized electronic cigarette liquid is configured to exit the device through the mouthpiece.

5. The device of claim 1, wherein the atomizer portion further comprises a wick element so that the wick element is wetted by the electronic cigarette liquid and the wetted wick element is heated by the heater element to vaporize the electronic cigarette liquid.

6. The device of claim 1, wherein the heater element is a coil.

7. The device of claim 6, wherein the coil is a sub-ohm coil.

8. The device of claim 7, wherein the heater element further comprises a first and second electrode at each side of the coil wherein the first and second electrodes electrically connect the coil to the power source.

9. The device of claim 1, wherein the housing further comprises an attachment mechanism that retains the removable tank in the housing.

10. The device of claim 9, wherein the mechanical connection of the removable tank is configured to mate with the attachment mechanism of the housing.

11. The device of claim 10, wherein the attachment mechanism of the housing is a biased strip and the mechanical connection of the removable tank is one or more shoulders wherein the one or more shoulders interact with the biased strip to retain the removable tank in the housing.

12. The device of claim 1, wherein the removable tank has a sealing mechanism that seals the liquid in the disposable tank when the removable tank is not coupled to the housing.

13. The device of claim 12, wherein the sealing mechanism releases the liquid from the removable tank into a region abutting the heater element when the removable tank is coupled to the housing.

14. The device of claim 1, wherein the power source is a battery.

15. The device of claim 1, wherein the power source further comprises an inductive charging element.

16. The device of claim 1, wherein the removable tank has an airflow mechanism.

17. A method, comprising:

inserting a removable tank into a tank receptacle of a housing configured to receive the removable tank, wherein the removable tank comprises;

a first side extending from a top side of the removable tank to a bottom side of the removable tank;

a second side opposite the first side;

an air inlet;

a cavity holding a liquid and capable of being at least partially received in the tank receptacle;

a mouthpiece that forms an air outlet, the mouthpiece formed on the top side of the removable tank, wherein the mouthpiece extends along the first side and is laterally spaced away from the second side and the cavity; and

an atomizer portion located at a lower portion adjacent the bottom side of the removable tank, the atomizer portion having a tank well and a heater element;

wherein the tank receptacle is configured to support the bottom side and the second side of the removable tank while exposing at least the mouthpiece, the air inlet and the first side of the removable tank when the removable tank is inserted to the tank receptacle;

releasing the liquid in the cavity into the atomizer portion when the removable tank is inserted into the housing; and

vaporizing, using the heater element in the atomizer portion, the liquid released into the atomizer portion.

18. The method of claim 17, further comprising removing the removable tank from the housing and inserting a new removable tank into the housing.

19. The method of claim 18, wherein removing the removable tank further comprises automatically sealing the disposable tank to prevent leakage of any liquid remaining in the removable tank.

20. The method of claim 17, wherein vaporizing the liquid further comprises wetting a wick element of the atomizer portion using the liquid and heating the wetted wick element using the heater element to vaporize the liquid.

21. The method of claim 17 further comprising retaining, by an attachment mechanism of the housing, the removable tank in the housing and providing power from the housing to the removable tank.

22. The method of claim 21, wherein retaining the removable tank further comprises mating a mechanical connection in the removable tank with the attachment mechanism in the housing to retain the removable tank in the housing.

23. A closed tank apparatus for use with an electronic cigarette, the apparatus comprising:

a removable tank that is configured to hold a liquid to be vaporized by the electronic cigarette, the removable tank comprising;

a first side extending from a top side to the bottom side of the removable tank;

a second side opposite the first side;

an air inlet;

a heater element;

a cavity capable of holding a liquid; and

a mouthpiece that forms an air outlet, the mouthpiece formed on the top side of the removable tank, wherein the mouthpiece extends along the first side and is laterally spaced away from the second side and the cavity;

wherein the air travels through a first path down from the air inlet towards the heater element, and then past the heater element and then through a second path upwards through the air outlet and the mouthpiece, the second path positioned between the cavity and the first side.

24. The apparatus of claim 23, wherein the removable tank is a closed tank.

25. The apparatus of claim 23, wherein the removable tank further comprises a mechanical connection configured to mate mechanism that mates with an attachment mechanism of a housing of the electronic cigarette.

26. The apparatus of claim 25, wherein the mechanical connection is one or more shoulders wherein the one or more shoulders are configured to interact with a biased strip of the housing to retain the removable tank in the housing.
