An inhaler (10) and atomization component (100) thereof. The atomization component (100) and a battery component (300) of the inhaler (10) are detachably connected. The atomization component (100) comprises: a liquid storage structure (120), an atomization core (140), and a movable member (160). A liquid storage cavity (122) configured to store liquid is formed inside of the liquid storage structure (120). The atomization core (140) and the liquid storage structure (120) are fixedly connected. The atomization core (140) comprises a liquid absorption core (142). The movable member (160) and the liquid storage structure (120) are movably connected. When the atomization component (100) is not connected to the battery component (300), the movable member (160) blocks the liquid storage structure (120) so as to separate a liquid in the liquid storage cavity (122) from the liquid absorption core (142), preventing the liquid in the liquid storage cavity (122) from being continually absorbed by the liquid absorption core (142) and volatilized. When the atomization component (100) is connected to the battery component (300), the movable member (160) moves to the battery component (300) so as to communicate the liquid storage cavity (122) and the liquid absorption core (142), and the liquid absorption core (142) absorbs the liquid for atomization. When the inhaler (10) is not used for a long period of time, the atomization component (100) can be separated from the battery component (300), the movable member (160) blocks the liquid storage structure (120) and prevents the liquid in the liquid storage cavity (122) from being volatilized.
