Abstract

Various embodiments of the present disclosure can include an electronic cigarette. The electronic cigarette can include a body portion, the body portion including a body proximal end and a body distal end, wherein the body portion includes an air inlet. The electronic cigarette can include a mouthpiece connected to the body proximal end. The electronic cigarette can include an atomizer disposed in the body portion. The electronic cigarette can include a backflow mitigation valve disposed in the electronic cigarette, wherein the backflow mitigation valve is closed in a naturally biased state.

First claim

What is claimed:

1. An electronic cigarette, comprising:
a body portion, the body portion including a body proximal end and a body distal end, wherein the body portion includes an air inlet;
a mouth piece connected to the body proximal end;
an atomizer disposed in the body portion;
a backflow mitigation valve disposed in the body portion between the atomizer and the air inlet, wherein the backflow mitigation valve is closed in a naturally biased state, wherein the backflow mitigation valve remains in a closed state respective of an orientation of the electronic cigarette; and
a porous material disposed between the backflow mitigation valve and the air inlet.

2. The electronic cigarette of claim 1 , wherein the backflow mitigation valve is disposed in the body distal end.

3. The electronic cigarette of claim 1 , further comprising a battery portion connected to the body distal end.

4. The electronic cigarette of claim 3 , wherein the backflow mitigation valve is disposed in the battery portion.

5. The electronic cigarette of claim 3 , wherein:
the battery portion includes a battery connector;
the battery connector is connected to the body distal end; and
the backflow mitigation valve is disposed in the battery connector.

6. The electronic cigarette of claim 1 , wherein the backflow mitigation valve is a duckbill valve.

7. The electronic cigarette of claim 1 , wherein the backflow mitigation valve is a reed valve.

8. The electronic cigarette of claim 7 , wherein the reed valve includes a double read valve.

9. The electronic cigarette of claim 1 , wherein the backflow mitigation valve includes an umbrella valve.

10. The electronic cigarette of claim 1 , wherein the backflow mitigation valve includes a spring ball valve.

11. The electronic cigarette of claim 1 , wherein the porous material includes hydrophobic properties.

12. The electronic cigarette of claim 1 , wherein the porous material includes oleophobic properties.

13. An electronic cigarette, comprising:
a body portion, the body portion including a body proximal end and a body distal end, wherein the body portion includes an air inlet;
a mouth piece connected to the body proximal end;
an atomizer disposed in the body portion;
a battery portion connected to the body distal end via a battery connector;
a backflow mitigation valve disposed in the battery connector, between the atomizer and the air inlet, wherein the backflow mitigation valve is a double duckbill valve, and wherein the double duckbill valve includes a pair of duckbill valves disposed orthogonal with respect to one another; and
a porous material disposed between the backflow mitigation valve and the air inlet configured to prevent moisture from traveling towards the air inlet.

14. The electronic cigarette of claim 13 , wherein the backflow mitigation valve is configured to allow air to enter the air inlet and prevent air from exiting the air inlet.

15. The electronic cigarette of claim 13 , wherein the backflow mitigation valve is configured to prevent fluid from exiting the backflow mitigation valve.

16. An electronic cigarette, comprising:
a body portion, the body portion including a body proximal end and a body distal end, wherein the body portion includes an air inlet;
a mouth piece connected to the body proximal end;
an atomizer disposed in the body portion;
a battery portion connected to the body distal end via a battery connector;
a backflow mitigation valve disposed in the battery connector between the atomizer and the air inlet, wherein the backflow mitigation valve is formed from a flexible material, and wherein the backflow mitigation valve is closed in a naturally biased state, wherein the backflow mitigation valve remains in a closed state respective of an orientation of the electronic cigarette; and
a porous material disposed between the backflow mitigation valve and the air inlet, wherein the porous material is an absorbent material.

17. The electronic cigarette of claim 16 , wherein the backflow mitigation valve is formed from a material that includes rubber.
