Abstract (en)

[origin: EP4159057A2] Disclosed are a heating body, an atomizer and an electronic atomization device. aerosol-generation substanceThe heating body comprises a compact base body, which has a liquid suction surface and an atomization surface arranged opposite each other and is provided with a plurality of micropores that penetrate the liquid suction surface and the atomization surface. The atomization surface is of the surface-treated wetting structure that is in communication with the micropores in a liquid guide manner, which increases the wetting area of the atomization surface, thereby improving the atomization efficiency.
