Abstract

An atomizer including an e-liquid tank, a mouthpiece, and a heating core. The e-liquid tank including an inner tube, an outer tube, and a connection wall. The inner tube is integrated with the outer tube and is disposed in the outer tube. The inner tube includes a first end and a second end, and the outer tube includes a third end and a fourth end. The mouthpiece is disposed on the first end of the inner tube. The first end of the inner tube is connected to the third end of the outer tube through the connection wall; an e-liquid accommodation space is formed between the inner tube and the outer tube. The inner tube includes an atomization channel. The mouthpiece includes a through hole, and the atomization channel communicates with the through hole. The heating core is disposed on the second end of the inner tube.

First claim

What is claimed is:

1 . An atomizer, comprising an e-liquid tank, a mouthpiece, and a heating core, the e-liquid tank comprising an inner tube, an outer tube, and a connection wall, wherein the inner tube is integrated with the outer tube and is disposed in the outer tube; the inner tube comprises a first end and a second end, and the outer tube comprises a third end and a fourth end; the mouthpiece is disposed on the first end of the inner tube; the first end of the inner tube is connected to the third end of the outer tube through the connection wall; an e-liquid accommodation space is formed between the inner tube and the outer tube; the inner tube comprises an atomization channel; the mouthpiece comprises a through hole, and the atomization channel communicates with the through hole; the heating core is disposed on the second end of the inner tube; and the inner tube comprises an e-liquid inlet corresponding to the heating core in position.

2 . The atomizer of claim 1 , wherein the e-liquid tank comprises a transparent or semitransparent material.

3 . The atomizer of claim 2 , wherein the e-liquid tank comprises glass, quartz, agate, jade, or ceramic.

4 . The atomizer of claim 1 , wherein the inner tube is coaxial with the outer tube, and the mouthpiece protrudes from the first end of the inner tube.

5 . The atomizer of claim 1 , wherein the e-liquid accommodation space comprises an opening between the second end of the inner tube and the fourth end of the outer tube; the atomizer further comprises a sealing element, and the sealing element is disposed in the opening.

6 . The atomizer of claim 5 , wherein one surface of the sealing element facing the e-liquid accommodation space is sloped, comprising a higher outer edge and lower central part.

7 . The atomizer of claim 5 , wherein the sealing element comprises a first through hole communicating with the atomization channel; the atomizer further comprises a base; the base comprises at least one air channel communicating with the atomization channel.

8 . The atomizer of claim 7 , wherein the sealing element is a puncturable sealing plug that is able to restore to its original state after puncturing; the base comprises at least one e-liquid injection hole, and the at least one e-liquid injection hole corresponds to the sealing plug.

9 . The atomizer of claim 8 , wherein the base comprises a bottom wall and a side wall; the bottom wall and the side wall define a cavity; the fourth end of the outer end extends into the cavity; the bottom wall comprises a second through hole communicating with the first through hole of the sealing element; the side wall comprises at least one air hole; the at least one air channel is disposed in the bottom wall and extends to communicate with the at least one air hole and the second through hole on two opposite ends; and the at least one e-liquid injection hole is disposed in the bottom wall.

10 . The atomizer of claim 9 , wherein the bottom wall protrudes outward with respect to the second through hole to form a hollow tubular first conductive electrode; the hollow tubular first conductive electrode comprises an outer wall having an external thread; a second conductive electrode is embedded in the first conductive electrode, and an insulation part is disposed between the first conductive electrode and the second conductive electrode.

11 . The atomizer of claim 1 , wherein the heating core comprises a first e-liquid absorption piece, a second absorption piece, and an electric heating element; the heating element is electrically connected to the first conductive electrode and the second conductive electrode.

12 . An electronic cigarette, comprising the atomizer of claim 1 and a battery module supplying power to the atomizer.
