Electronic atomization device, and componets and preparation method and application thereof

A heating component comprising:

• a liquid guide substrate, wherein the liquid guide substrate comprises
• a body including a first surface and a second surface arranged opposite to each other;
• and
• one or more porous layer being arranged inside the body, the one or more porous layer including a plurality of liquid passing through holes and a plurality of bypass holes, the plurality of liquid passing through holes extending through the first surface and the second surface in a first direction, the plurality of bypass holes being communicating with at least one of the plurality of liquid passing through holes in a second direction, and the plurality of liquid passing through holes or the plurality of bypass holes being curved holes;
• a heating element being embedded in the body or arranged on the first surface of the body, and the first surface being an atomization surface.

An atomizer comprising:

• a liquid storage;
• and
• a liquid guide substrate, wherein the liquid guide substrate comprises
• a body including a first surface and a second surface arranged opposite to each other;
• and
• one or more porous layer being arranged inside the body, the one or more porous layer including a plurality of liquid passing through holes and a plurality of bypass holes, the plurality of liquid passing through holes extending through the first surface and the second surface in a first direction, the plurality of bypass holes being communicating with at least one of the plurality of liquid passing through holes in a second direction, and the plurality of liquid passing through holes or the plurality of bypass holes being curved holes;
• and
• a heating element being embedded in the body or arranged on the first surface of the body, wherein the first surface of the body is an atomization surface, the second surface of the body is a liquid absorbing surface, and the liquid absorbing surface is in communication with the liquid storage portion.
