Atomization core, atomizer, and electronic atomization device

An atomizer comprising:

• a liquid storage being configured to store a liquid atomization medium;
• and
• an atomization core atomizing the liquid atomization medium, the atomization core comprising:
• a heating element;
• and
• a porous glass-ceramic substrate, and the porous glass-ceramic substrate comprises a plurality of glass-ceramic bubbles;
• adjacent glass-ceramic bubbles of the plurality of glass-ceramic bubbles are directly bonded to each other through sintering;
• some of the plurality of glass-ceramic bubbles have openings;
• and
• cavities in the plurality of glass-ceramic bubbles having the openings are in communication with each other through the openings to form a plurality of pores, and the plurality of pores extend through the porous glass-ceramic substrate and reach a surface of the porous glass-ceramic substrate.
