Atomizer comprising bowl-shaped ceramic core

An atomizer, comprising an e-liquid injection and vapor discharging module, wherein the e-liquid injection and vapor discharging module comprises an outer tube, an inner tube disposed in the outer;

• tube, a seal ring, and a ceramic core;
• the seal ring comprises a hollow center;
• the ceramic core comprises a bottom wall having a bottom surface, a side wall extending upwards from the bottom wall, and a flange extending out from the side wall;
• wherein:
• the inner tube is configured to accommodate e liquid;
• the ceramic core is configured to atomize the e-liquid in the inner tube to produce a vapor;
• and
• a cavity formed between the outer tube and the inner tube is configured to guide air and discharge the vapor;
• the seal ring is disposed on the flange of the ceramic core and around the side wall of the ceramic core;
• a bottom end of the inner tube is disposed on the flange of the ceramic core, and the seal ring is disposed between the bottom end of the inner tube and the flange of the ceramic core;
• whereby the inner tube is supported and sealed by the ceramic core;
• the ceramic core is in the shape of a concave bowl;
• the ceramic core further comprises a heating wire disposed on the bottom surface of the bottom wall, wherein the bottom surface is a substantially flat surface;
• and
• the ceramic core is configured to discharge the vapor out from the bottom surface into the cavity formed between the outer tube and the inner tube.
