Abstract
A purification device includes a housing and a liquid storage tank. The liquid storage tank is detachably placed in a placement cavity in the housing. A rotary member is located on the liquid storage tank, and the rotary member is rotatably connected to a top end of a side wall of the liquid storage tank. A first snap-fit portion is located on the rotary member, a second snap-fit portion matching the first snap-fit portion is located at a top end of the placement cavity. In response to determining that the liquid storage tank is located in the placement cavity and the rotary member rotates to a horizontal position, the first snap-fit portion and the second snap-fit portion match each other to clamp the liquid storage tank in the placement cavity.
