Abstract (en)

[origin: EP4166014A1] This application provides an atomizer, an electronic atomization device, and a seal element for an atomizer. The atomizer includes: a liquid storage cavity, configured to store a liquid substrate; a porous body, being in fluid communication with the liquid storage cavity to receive the liquid substrate; a heating element, combined with the porous body, and configured to heat at least a part of the liquid substrate in the porous body to generate an aerosol; a holder, configured to hold the porous body; and a seal element, arranged between the holder and the porous body, and configured to seal a gap between the holder and the porous body, where the seal element includes a plurality of side walls surrounding the porous body along a circumferential direction of the porous body and an upper end wall. The seal element includes convex ribs extending on outer surfaces of the plurality of side walls and the upper end wall or on inner surfaces of the plurality of side walls and the upper end wall, and the convex ribs are connected into at least one closed ring. The seal element can seal the porous body and the holder through the convex rib after assembly.
