DETAILED DESCRIPTION

To further illustrate, embodiments detailing a glass atomizer are described below. It should be noted that the following embodiments are intended to describe and not to limit the disclosure.

As shown in FIGS. 1-5, the disclosure provides a glass atomizer comprising a mouthpiece 1, a seal ring 2, a seal plug 3, an outer glass tube 4, an inner glass tube 5, a seal gasket 6, a ceramic heating core 7, a silicone fixing part 8, a fixed ring 9, a base 10, a joint 11, and an insulation ring 12. The silicone fixing part 8 comprises a recess 14. The base 10 comprises an air hole 13. The inner glass tube 5 is disposed in the outer glass tube 4. The inner glass tube 5 comprises a top end. The outer edge of the top end comprises a plurality of grooves 15. The top end is integrated with the inner wall of the outer glass tube 4. The seal gasket 6 comprises a hollow center and is disposed around the ceramic heating core 7. One end of the ceramic heating core 7 is embedded in the bottom opening of the inner glass tube 5. The bottom end of the inner glass tube 5 abuts against the seal gasket 6 or the seal gasket 6 is disposed around the bottom end of the inner glass tube 5. The fixed ring 9 is disposed around the base 10. The bottom end of the outer glass tube 4 is disposed around the fixed ring 9. The ceramic heating core 7 is disposed on the silicone fixing part 8. The silicone fixing part 8 is disposed in the base 10. The insulation ring 12 is disposed in the bottom of the base 10 to separate the positive lead from the negative lead of the ceramic heating core 7 and meanwhile fix the negative lead. The joint 11 is disposed in the insulation ring 12 to fix the positive lead of the ceramic heating core 7. The seal plug 3 is disposed on the top of the inner glass tube 5 and is configured to seal a top opening of the inner glass tube 5 after the inner glass tube 5 is filled with e-liquid. The seal ring 2 is disposed around the mouthpiece 1 to seal the gap between the mouthpiece 1 and the outer glass tube 4 thus preventing the leakage of the air and the vapor. The mouthpiece 1 is disposed on the top of the outer glass tube 4.

When injected into the inner glass tube 5, the e-liquid penetrates into the surface of the ceramic heating core 7, and no drops are formed on the surface of the ceramic heating core 7 and no drops leak into between the inner glass tube 5 and the outer glass tube 4. The air enters the atomizer via the space 910 between the fixed ring 9 and the base 10, flows through the air hole 13 on the base 10 and the recess 14 on the silicone fixing part 8, drives the vapor produced by the ceramic heating core 7 to pass through the space between the inner glass tube 5 and the outer glass tube 4, and is discharged from the plurality of grooves 15 of the top end of the inner glass tube 5 for user's inhaling via the mouthpiece 1.

In the disclosure, the grooves 15 and the recess 14 are configured for air ventilation and can present in different forms. For example, the grooves are disposed on the inner edge of the top end of the inner glass tube 5, or the grooves are replaced by through holes, etc. The grooves 15 of the inner glass tube 5 are not necessarily on the top end of the inner glass tube 5, but may be on the middle part of the inner glass tube. The top of the inner glass tube 5 and the top of the outer glass tube 4 may be flush, and the mouthpiece 1 is disposed on the top of the outer glass tube 4. The material of the outer glass tube 4 and the inner glass tube 5 can also be replaced by the same material selected from 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 following advantages are associated with the glass atomizer of the disclosure:

1. The glass atomizer comprises an outer glass tube and an inner glass tube, and the vapor produced by the ceramic heating core passes through the space between the inner glass tube 5 and the outer glass tube 4. This simplifies the member for vapor discharge of the atomizer.

2. The ceramic heating core 7 is in the shape of a concave bowl 701, and comprises a protruding edge 702, a bottom, and a heating wire disposed on the bottom, which is novel.

3. The e-liquid is directly injected into the atomizer via the top opening of the inner glass tube, which is easy to operate.

4. The air hole on the base of the atomizer is covered by the fixed ring disposed on the base. The air enters the atomizer from the space between the fixed ring and the base, and then flows to the air hole. The design is novel.

It will be obvious to those skilled in the art that changes and modifications may be made, and therefore, the aim in the appended claims is to cover all such changes and modifications.
