Abstract

The present invention concerns an electronic smoking device that includes a battery portion ( 12 ) comprising a battery ( 18 ), an atomizer/liquid reservoir portion ( 14 ) comprising a multicameral liquid reservoir ( 34 ), and an atomizer ( 26 ) operable when connected to the battery ( 18 ) to atomize liquid stored in the multicameral liquid reservoir ( 34 ). The multicameral liquid reservoir ( 34 ) comprises a first chamber ( 202 ) comprising an unflavored fluid, a second chamber ( 204 ) comprising a flavored fluid, the first chamber ( 202 ) and the second chamber ( 204 ) being disposed in communication with each other via an opening ( 206 ), and a plurality of reservoir walls ( 208 ) enclosing the two chambers. A portion of the plurality of reservoir walls ( 208 ) enclosing the second chamber ( 204 ) comprising a flexible portion ( 40 ), the flexible portion ( 40 ) when acted upon causing the flavored fluid to migrate from the second chamber ( 204 ) to the first chamber ( 202 ) through the opening ( 206 ).

Claims (29)

1. An electronic cigarette ( 10 ), comprising:

a battery portion ( 12 ) comprising a battery ( 18 ),

an atomizer/liquid reservoir portion ( 14 ) comprising a multicameral liquid reservoir ( 34 ), and an atomizer ( 26 ) operable when connected to the battery ( 18 ) to atomize liquid stored in the multicameral liquid reservoir ( 34 ), wherein said multicameral liquid reservoir ( 34 ) comprising:

a first chamber ( 202 ) comprising an unflavored fluid,

a second chamber ( 204 ) comprising a flavored fluid,

said first chamber ( 202 ) and said second chamber ( 204 ) disposed in communication with each other via an opening ( 206 ), and

a plurality of reservoir walls ( 208 ) enclosing said first ( 202 ) and second ( 204 ) chamber,

wherein a portion of said plurality of reservoir walls ( 208 ) enclosing said second chamber ( 204 ) comprising a flexible portion ( 40 ), said flexible portion ( 40 ) when acted upon causing said flavored fluid to migrate from the second chamber ( 204 ) to the first chamber ( 202 ) through said opening ( 206 ).

2. The electronic cigarette ( 10 ) of claim 1 , wherein when acting upon said flexible portion ( 40 ) an internal pressure of said flavored fluid is increased causing said flavored fluid to migrate from the second chamber ( 204 ) to the first chamber ( 202 ).

3. The electronic cigarette ( 10 ) of claim 1 , wherein a volume of said first chamber ( 202 ) is larger than a volume of said second chamber ( 204 ).

4. The electronic cigarette ( 10 ) of claim 1 , wherein said flexible portion ( 40 ) forming an outside portion of said atomizer/liquid reservoir portion ( 14 ) of the electronic cigarette ( 10 ).

5. The electronic cigarette ( 10 ) of claim 1 , wherein said second chamber ( 204 ) comprising a capsule ( 300 ) comprising said flavored fluid, and wherein said capsule ( 300 ) is adapted to break due to pressure exerted upon the capsule ( 300 ) via said flexible portion ( 40 ).

6. The electronic cigarette ( 10 ) of claim 5 , wherein the capsule ( 300 ) is disposed within said second chamber ( 204 ) between said flexible portion ( 40 ) of said plurality of reservoir walls ( 208 ) and said opening ( 206 ).

7. The electronic cigarette ( 10 ) of claim 1 , wherein said opening ( 206 ) comprising a first valve ( 400 ).

8. The electronic cigarette ( 10 ) of claim 1 , wherein a portion of said plurality of walls ( 208 ) enclosing said second chamber ( 208 ) comprising a second valve ( 400 ).

9. The electronic cigarette ( 10 ) of claim 8 , wherein said second valve ( 400 ) is a unidirectional valve capable of functioning as an air inlet.

10. The electronic cigarette ( 10 ) of claim 7 , wherein said first valve ( 400 ) is a unidirectional valve.

11. The electronic cigarette ( 10 ) of claim 7 , wherein said first valve ( 400 ) is a bidirectional pin hole valve.

12. The electronic cigarette ( 10 ) of claim 7 , wherein the atomizer ( 26 ) comprising a heating coil ( 28 ) and a wick ( 30 ), and wherein said wick ( 30 ) is disposed in the proximity of the opening ( 206 ) between said first ( 202 ) and second chambers ( 204 ).

13. An atomizer/liquid reservoir portion ( 14 ), comprising:

a multicameral liquid reservoir ( 34 ), and

an atomizer ( 26 ) operable when connected to a battery ( 18 ) of an electronic cigarette ( 10 ) to atomize liquid stored in the multicameral liquid reservoir ( 34 ), wherein the multicameral liquid reservoir ( 34 ) comprising:

a first chamber ( 202 ) comprising an unflavored fluid,

a second chamber ( 204 ) comprising a flavored fluid,

said first chamber ( 202 ) and said second chamber ( 202 ) disposed in communication with each other via an opening ( 206 ), and

a plurality of reservoir walls ( 208 ) enclosing said first ( 202 ) and second chamber ( 204 ),

wherein a portion of said plurality of reservoir walls ( 208 ) enclosing said second chamber ( 204 ) comprising a flexible portion ( 40 ), said flexible portion ( 40 ) when pressed causing said flavored fluid to migrate from the second chamber ( 204 ) to the first chamber ( 202 ) through said opening ( 206 ).

14. The atomizer/liquid reservoir portion ( 14 ) of claim 13 , wherein when pressing said flexible portion ( 40 ) an internal pressure of said flavored fluid is increased causing said flavored fluid to migrate from the second chamber ( 204 ) to the first chamber ( 202 ).

15. The atomizer/liquid reservoir portion ( 14 ) of claim 13 , wherein said flexible portion ( 40 ) forming an outside portion of said atomizer/liquid reservoir portion ( 14 ) of electronic cigarette ( 10 ).
