Abstract

A glass atomizer includes a member for e-liquid injection and vapor discharge. The member for e-liquid injection and vapor discharge includes an outer glass tube and an inner glass tube disposed in the outer glass tube. The inner glass tube includes a top end. The top end includes a disk edge; the top end is integrated with the inner wall of the outer glass tube. The disk edge includes an e-liquid injection hole. The e-liquid injection hole communicates with a space between the outer glass tube and the inner glass tube.

First claim

What is claimed is:

1. An atomizer, comprising a member for e-liquid injection and vapor discharge, wherein:
the member for e-liquid injection and vapor discharge comprises an outer tube, an inner tube disposed in the outer tube, a seal gasket, and a ceramic heating core;
the inner tube comprises a top end; the top end comprises a disk edge; the top end is integrated with an inner wall of the outer glass tube; the disk edge comprises an e-liquid injection hole; and the e-liquid injection hole communicates with a space between the outer tube and the inner tube;
wherein the outer tube and the inner tube comprise glass, toughened glass, high temperature resistant poly-cyclohexylenedimethylene terephthalate glycol (PCTG), high temperature resistant resin, high temperature resistant acrylic, an explosion-proof film, or a combination thereof;
the space between the outer tube and the inner tube is adapted for storing an e-liquid;
the seal gasket and the ceramic heating core each comprises a central through hole, and the seal gasket is disposed in the central through hole of the ceramic heating core;
a bottom opening of the inner tube is disposed in the central through hole of the ceramic heating core; and a bottom end of the inner tube abuts against the seal gasket or the seat gasket is disposed around the bottom end of the inner tube; whereby the inner tube is supported by the ceramic heating core;
the ceramic heating core is in the shape of a disc; and the ceramic heating core comprises a top flat circular surface, a bottom flat circular surface opposite to the top flat circular surface, a conical edge, and a heating wire; wherein:
the conical edge extends from the top flat circular surface in a direction away from the bottom flat circular surface; and
the conical edge comprises a conical surface gradually reduced in diameter in the direction away from the bottom flat circular surface; the central through hole of the ceramic heating core extends through the conical edge, the top flat circular surface, and the bottom flat circular surface; and
the heating wire is disposed on the bottom flat circular surface;

the conical edge of the ceramic heating core is disposed adjacent to the space between the outer tube and the inner tube; and
the surfaces on the conical edge of the ceramic heating core are adapted for conveying the e-liquid from the space between the outer tube and the inner tube to the bottom flat circular surface to be atomized.

2. The atomizer of claim 1 , wherein the member for e-liquid injection and vapor discharge further comprises a fixed ring and a base; the fixed ring is disposed around the base; and a bottom end of the outer tube is disposed around the fixed ring.

3. The atomizer of claim 2 , wherein the base comprises an air hole.

4. The atomizer of claim 3 , wherein the member for e-liquid injection and vapor discharge further comprises a silicone fixing part; the ceramic heating core is disposed on the silicone fixing part; and the silicone fixing part is disposed in the base.

5. The atomizer of claim 4 , wherein the silicone fixing part comprises a central air tube.

6. The atomizer of claim 5 , wherein the member for e-liquid injection and vapor discharge further comprises a seal plug; the seal plug comprises a bottom end comprising a sealing protrusion; the seal plug is disposed on a top of the inner tube and the sealing protrusion is configured to seal the e-liquid injection hole of the inner tube after the space between the inner tube and the outer tube is filled with e-liquid.

7. The atomizer of claim 6 , wherein the member for e-liquid injection and vapor discharge further comprises a joint and an insulation ring; the insulation ring is disposed in a bottom of the base to separate a positive lead from a negative lead of the ceramic heating core and meanwhile fix the negative lead; and the joint is disposed in the insulation ring to fix the positive lead of the ceramic heating core.

8. The atomizer of claim 7 , wherein the member for e-liquid injection and vapor discharge further comprises a mouthpiece and a seal ring; the seal ring is disposed around the mouthpiece to seal a gap between the mouthpiece and the outer tube thus preventing the leakage of air and vapor; and the mouthpiece is disposed on a top of the outer tube and is disposed around the seal plug.
