Glass atomizer having inner glass tube integrated with outer glass tube

1. A glass atomizer, wherein the glass atomizer comprises an outer glass tube and an inner glass tube disposed in the outer glass tube; the inner glass tube comprises a top end; an outer edge of the top end comprises a plurality of grooves; and the top end is integrated with an inner wall of the outer glass tube.

2. The glass atomizer of claim 1 , wherein the glass atomizer further comprises a seal gasket and a ceramic heating core; the seal gasket comprises a hollow center and is disposed around the ceramic heating core; one end of the ceramic heating core is embedded in a bottom opening of the inner glass tube; a bottom end of the inner glass tube abuts against the seal gasket or the seal gasket is disposed around the bottom end of the inner glass tube.

3. The glass atomizer of claim 2 , wherein the ceramic heating core is in the shape of a concave bowl, and comprises a protruding edge.

4. The glass atomizer of claim 3 , wherein the glass atomizer further comprises a fixed ring and a base; the fixed ring is disposed around the base; and a bottom end of the outer glass tube is disposed around the fixed ring.

5. The glass atomizer of claim 4 , wherein the base comprises an air hole.

6. The glass atomizer of claim 5 , wherein the glass atomizer 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.

7. The glass atomizer of claim 6 , wherein the silicone fixing part comprises a recess.

8. The glass atomizer of claim 7 , wherein the glass atomizer further comprises a seal plug disposed on a top of the inner glass tube and configured to seal a top opening of the inner glass tube after the inner glass tube is filled with e-liquid.

9. The glass atomizer of claim 8 , wherein the glass atomizer further comprises a joint and an insulation ring; the insulation ring is disposed in a bottom of the base; and the joint is disposed in the insulation ring.

10. The glass atomizer of claim 9 , wherein the glass atomizer 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 glass tube thus preventing the leakage of air and vapor; and the mouthpiece is disposed on a top of the outer glass tube.

11. The glass atomizer of claim 10 , wherein when in use, the air enters the atomizer via a space between the fixed ring and the base, flows through the air hole on the base and the recess on the silicone fixing part, drives the vapor produced by the ceramic heating core to pass through the space between the inner glass tube and the outer glass tube, and is discharged from the plurality of grooves of the top end of the inner glass tube for user's inhaling via the mouthpiece.

12. The glass atomizer of claim 11 , wherein the outer glass tube and the inner glass tube comprise 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.
