Description

DESCRIPTION The disclosure relates to a glass atomizer. Conventionally, the atomizers include a cylindrical ceramic core and a spiral heating wire disposed in the cylindrical ceramic core. The spiral heating wire has a low heating power, and thus only a small amount of vapor is produced. EP-A-3 040 095 discloses an atomizer. The present invention relates to an atomizer as set out in claim 1. In a class of this embodiment, the member for e-liquid injection and vapor discharge 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. In a class of this embodiment, the ceramic heating core is in the shape of a hollow convex disc, and comprises a bottom and a heating wire disposed on the bottom. In a class of this embodiment, 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 glass tube is disposed around the fixed ring.
