Abstract

The present disclosure relates to a cartridge for an electronic cigarette. The cartridge includes a cartridge body defining a smoke channel for smoke flowing therethrough and a reservoir chamber surrounding the smoke channel for storing liquid solution, the reservoir chamber comprising an opening which communicates the interior of the reservoir chamber with the exterior of the reservoir chamber; and a sealing member secured to the cartridge body, the sealing member comprising a first sealing portion for sealing the opening.

Claims

1. A cartridge for an electronic cigarette comprising:

a cartridge body defining a smoke channel for smoke flowing therethrough and a reservoir chamber surrounding the smoke channel for storing liquid solution, the reservoir chamber comprising an opening which communicates the interior of the reservoir chamber with the exterior of the reservoir chamber; and

a sealing member secured to the cartridge body, the sealing member comprising a first sealing portion for sealing the opening;

the cartridge comprising a resilient cover, the resilient cover comprising a fixing part and a moving part, the fixing part being fixed on the cartridge body and the moving part covering the opening resiliently;

wherein the resilient cover is located within the reservoir chamber, the cartridge body comprises a tube for separating the reservoir chamber from the smoke channel, the resilient cover is substantially annular-shaped, the external diameter of the resilient cover is equal to or slightly smaller than the external diameter of the reservoir chamber, the inner periphery of the resilient cover is fixed on a free end of the tube, and the outer periphery of the resilient cover extends laterally from the tube to or adjacent to the inner wall of the reservoir.

2. The cartridge as described in claim 1, wherein the sealing member comprising a second sealing portion for sealing an inlet of the smoke channel.

3. The cartridge as described in claim 2, wherein the opening and the inlet are coplanar.

4. The cartridge as described in claim 3, wherein the first sealing portion and the opening are substantially annular-shaped, and the second sealing portion and the inlet are substantially circular-shaped.

5. The cartridge as described in claim 1, wherein the sealing member is made of silver paper.

6. The cartridge as described in claim 1, wherein at least a portion of the cartridge body is transparent.

7. The cartridge as described in claim 1, wherein the cartridge body comprises a suction nozzle portion, an embedding portion, and a transition portion connecting the suction nozzle portion with the embedding portion, the smoke channel extends through the suction nozzle portion, the transition portion and the embedding portion in sequence.

8. The cartridge as described in claim 1, wherein the cartridge body comprises a suction nozzle portion with a plurality of anti-slip protrusions formed on the outer surface thereof, and the plurality of anti-slip protrusions is spaced from each other.

9. The cartridge as described in claim 1, wherein the cartridge body comprises an embedding portion, and a pair of latching protrusions is formed on the outer surface of the embedding portion.

10. A cartridge for an electronic cigarette comprising:

a cartridge body defining a reservoir chamber for storing liquid solution, the reservoir chamber comprising an opening which communicates the interior of the reservoir chamber with the exterior of the reservoir chamber; and

an resilient cover comprising a fixing part and a moving part, the fixing part being fixed on the cartridge body and the moving part covering the opening resiliently;

wherein the cartridge body comprises a tube for separating the reservoir chamber from the smoke channel, the resilient cover is substantially annular-shaped, the external diameter of the resilient cover is equal to or slightly smaller than the external diameter of the reservoir chamber, the inner periphery of the resilient cover is fixed on a free end of the tube, and the outer periphery of the resilient cover extends laterally from the tube to or adjacent to the inner wall of the reservoir.

11. The cartridge as described in claim 10, wherein the cartridge body further defines a smoke channel for smoke flowing therethrough, the smoke channel extends longitudinally through the cartridge body, and the reservoir chamber surrounds the smoke channel.

12. The cartridge as described in claim 11, wherein the cartridge body comprises a suction nozzle portion, an embedding portion, and a transition portion connecting the suction nozzle portion with the embedding portion, the smoke channel extends through the suction nozzle portion, the transition portion and the embedding portion in sequence.

13. The cartridge as described in claim 11, wherein the cartridge body comprises a suction nozzle portion with a plurality of anti-slip protrusions formed on the outer surface thereof, and the plurality of anti-slip protrusions is spaced from each other.

14. The cartridge as described in claim 11, wherein the cartridge body comprises an embedding portion, and a pair of latching protrusions is respectively formed on two opposite sides of the outer surface of the embedding portion.

15. The cartridge as described in claim 11, wherein the opening are substantially annular-shaped, and the inlet are substantially circular-shaped.

19. The cartridge as described in claim 10, wherein the resilient cover is located within the reservoir chamber.

20. The cartridge as described in claim 10, wherein at least a portion of the cartridge body is transparent.

16. The cartridge as described in 11, wherein the sealing member comprises a first sealing portion for sealing the opening.

17. The cartridge as described in claim 16, wherein the sealing member comprises a second sealing portion for sealing an inlet of the smoke channel.

18. The cartridge as described in claim 17, wherein the first sealing portion is pierced through to communicate the reservoir chamber with an atomizing device when the cartridge is connected to the atomizing device to allow the liquid solution to be atomized by the atomizing device;
