Abstract

An atomizer (100) and an aerosol generating device, the atomizer comprising a liquid storage member (10), a bottom cover assembly (30), a ventilation assembly (50), an atomization assembly (70) and a mouthpiece assembly (90). When the mouthpiece assembly (90) is located in a position to be activated, an electrode column (55) is housed within the bottom cover assembly (30) along with a pipe seat (51), and the bottom cover assembly (30) closes a liquid inlet (5301). When the mouthpiece assembly (90) is located in a use position, the electrode column (55) is exposed outside of the bottom cover assembly (30) along with the tube seat (51), and the liquid inlet (5301) communicates with a liquid storage cavity (11) and an atomization cavity (530). The bottom cover assembly (30) closes the liquid inlet (5301), and separates the atomization assembly (70) within a ventilation pipe (53) from the liquid storage cavity (11), thus avoiding the atomization assembly (70) from being immersed for a long time in an aerosol-forming matrix. Even if the present invention is not used for a long time, deterioration or leakage problems will not occur. In addition, since the electrode column (55) is only exposed outside of the bottom cover assembly (30) when the mouthpiece assembly (90) is in the use position and is electrically connected to a power supply device to activate, the atomizer (100) and the power supply device are prevented from being accidentally activated.
