Abstract: A vaporization assembly includes: a porous substrate; and a heating element. The porous substrate has a vaporization surface, and the heating element is arranged on the vaporization surface. The porous substrate includes a fence structure, and the fence structure surrounds the vaporization surface, defining an accommodating groove. In an embodiment, the fence structure is arranged on a peripheral edge of a vaporization end of the porous substrate, and an area of the vaporization end within the fence structure forms the vaporization surface.

Abstract: A heating body includes: a porous ceramic body having a preheating member, the preheating member including a porous infrared ceramic structure; and a heating member located on the porous ceramic body, the heating member providing heat for the preheating member and vaporizing preheated liquid. In an embodiment, the porous ceramic body includes a substrate. The preheating member is located on the substrate. The substrate includes a porous ceramic structure. The heating member is completely located in the preheating member and is close to the substrate, or is located at a junction of the substrate and the preheating member.

Abstract: A vaporization core, a method of manufacturing the same, and an electronic vaporization device comprising the same are disclosed. The vaporization core includes a tubular porous substrate for forming a vaporization cavity and configured to guide liquid outside the tubular porous substrate into the vaporization cavity and a heating element disposed on an inner wall of the tubular porous substrate and configured to heat and vaporize the liquid guided into the vaporization cavity.
