Abstract: Some embodiments of the present disclosure provide a mounting structure, a lower water outlet tank, and an air treatment device. The mounting structure is used for mounting a water outlet valve (3) to a water tank body (2) of a lower water outlet tank. The mounting structure includes a rotating connection member (1) on which the water outlet valve (3) is disposed and which includes a rotating operation portion (11) and a first cooperation portion (12) connected with each other. The mounting structure further includes a second cooperation portion (21) disposed on the water tank body (2), the rotating operation portion (11) is rotated by a predetermined angle, such that the first cooperation portion (12) and the second cooperation portion (21) is converted between a first state of separation and a second state of mutual occlusion.

Abstract: A cross-flow impeller mounting structure includes a housing and an impeller shaft support structure mounted on the housing and adapted to mount and support one end of a cross-flow impeller shaft away from a motor; the housing is adapted to mount a cross-flow impeller and match the cross-flow impeller to form an air duct; the housing includes: a side wall; a first end wall connected to one end of the side wall and provided with a first mounting through hole having an aperture which matches an outer diameter of the motor driving the cross-flow impeller to rotate and is adapted to mount the motor; a second end wall connected to the other end of the side wall and provided with a second mounting through hole for the cross-flow impeller to mount; the second end wall, the first end wall and the side wall encloses a cavity receiving the cross-flow impeller.
