Atomizer and electronic atomization device

Abstract

An atomizer and an electronic atomization device are provided. The atomizer includes: a liquid guide element that includes an atomization surface and a liquid absorbing surface; a heating element for heating a liquid substrate absorbed by the liquid guide element to generate an aerosol; and a first bracket that includes a partition portion, a first chamber and a second chamber. The partition portion isolates the first chamber from the second chamber, and includes a first through hole communicating the first chamber with the second chamber. The liquid guide element is at least partially accommodated in the second chamber. The atomization surface faces the first chamber, and the atomization surface is for the aerosol to escape and enter the first chamber through the first through hole.
