ATOMIZATION DEVICE

Disclosed is an atomization device (10). The atomization device (10) comprises an air inlet (11), an air outlet (12) and an atomization cavity (13). The atomization cavity (13) is in communication with the air inlet (11) and the air outlet (12) respectively, an atomization assembly (14) is arranged in the atomization cavity (13), and a part of an inner wall of the atomization cavity (13) that is close to the atomization assembly (14) is provided with a first capillary liquid-absorbing structure (15), wherein after the first capillary liquid-absorbing structure (15) absorbs an aerosol matrix, the temperature of a cavity wall of the atomization cavity (13) at the position of the first capillary liquid-absorbing structure (15) can be reduced along with the endothermic atomization of the aerosol matrix. The above means can improve the structural stability of the atomization device and improve the liquid leakage prevention effect of the atomization device.
