Heating assembly, vaporizer, and electronic vaporization device

A vaporizer, comprising:

• a liquid storage cavity, and
• a heating assembly, the heating assembly comprising:
• a first substrate having a first surface and a second surface arranged opposite one another;
• and
• a second substrate having a third surface and a fourth surface arranged opposite one another,
• wherein the second surface and the third surface are arranged opposite one another so as to form therebetween a gap,
• wherein a liquid inlet is formed on an edge of the first substrate, or by an edge of the first substrate with another component,
• wherein the second substrate comprises a plurality of second that fluidically communicate the gap and the fourth surface, and
• wherein the gap fluidically communicates the plurality of second micropores and the liquid inlet.

An electronic vaporization device, comprising:

• a vaporizer including a liquid storage cavity and a heating assembly;
• and
• a main unit configured to supply electric energy to the vaporizer and control the heating assembly so as to vaporize an aerosol-generation substrate,
• wherein the heating assembly comprises:
• a first substrate, comprising a first surface and a second surface arranged opposite one another, and
• a second substrate, comprising a third surface and a fourth surface arranged opposite one another,
• wherein the second surface and the third surface are arranged opposite one another to form therebetween a gap of changing height,
• wherein a liquid inlet is formed on an edge of the first substrate, or by an edge of the first substrate with another component,
• wherein the second substrate comprises a plurality of second micropores fluidically communicating the gap and the fourth surface, and
• wherein the gap fluidically communicates the plurality of second micropores and the liquid inlet.
