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 porous body for an electronic vaporization device includes: a first surface; a second surface opposite to the first surface; and at least two unit layers sequentially arranged along a direction from the first surface to the second surface, one unit layer of the at least two unit layers comprising at least a liquid storage advantage layer or a liquid locking advantage layer, and each unit layer of a remainder of the at least two unit layers comprising a liquid storage advantage layer and a liquid locking advantage layer combined with the liquid storage advantage layer.

Abstract: A heating assembly includes: a porous ceramic substrate for guiding a to-be-vaporized substrate; and a heating layer for heating and vaporizing the to-be-vaporized substrate. The heating layer includes a porous structure. The heating layer is partially filled in the porous ceramic substrate. In an embodiment, a portion of the heating layer is filled in the porous ceramic substrate along a thickness direction, and an other portion thereof is disposed outside the porous ceramic substrate.
