Abstract (en)
[origin: EP4066660A1] Provided are an atomization assembly and an electronic cigarette. The atomization assembly comprises an e-liquid reservoir (1), a porous body (2), and a heating element (3). The e-liquid reservoir (1) comprises an e-liquid storage cavity (b) used for storing e-liquid. The porous body (2) is used for adsorbing e-liquid in the e-liquid storage cavity (b); the porous body (2) comprises an e-liquid contact surface (pi), an e-liquid atomization surface (p2) and an air inlet surface; the porous body (2) adsorbs the e-liquid in the e-liquid storage cavity (b) by means of the e-liquid contact surface (p1); the air inlet surface is used for allowing gas to flow into the porous body (2) and flow into the e-liquid storage cavity (b) by means of the porous body (2); the distance between the air inlet surface and the e-liquid contact surface (p1) is smaller than the distance between the e-liquid atomization surface (p2) and the e-liquid contact surface (p1), and at least part of the heating element (3) is in contact with the e-liquid atomization surface (p2) so as to atomize the e-liquid on the e-liquid atomization surface (p2). During operation, the porous body (2) can provide enough e-liquid for the electric heating element, and therefore burnt smell can be avoided.
