Porous ceramic atomizing core with boss structure

The utility model relates to the technical field of ceramic heating bodies, in particular to a porous ceramic atomizing core with a boss structure, which comprises a porous ceramic base body, the outer surface of the porous ceramic base body comprises an atomizing surface positioned at the bottom of the porous ceramic base body and an oil sealing surface positioned at the upper end of the porous ceramic base body, and a heating circuit is printed on the atomizing surface. A plurality of boss structures are arranged on the oil sealing surface, an oil guide groove is formed between every two adjacent boss structures at intervals, and the bottom surface of each oil guide groove is an oil guide surface. The boss structure is arranged on one side of the oil sealing face of the porous ceramic base body to form the oil guide groove, the contact area with tobacco tar is remarkably increased through the bottom face of the formed oil guide groove and the side surface of the boss structure, gas exchange is facilitated,
