[0002] A floor scrubber is a cleaning machine suitable for cleaning hard floors while sucking out wastewater and taking it away from the site. After the floor scrubber is used, some impurities will remain in the water tank inside the machine body. In order to facilitate the treatment of the impurities in the water tank, the housing of the floor scrubber is usually released through a locking structure, and then the housing is removed to facilitate subsequent cleaning of the water tank.

[0003] For example, a clean water tank assembly and a floor scrubber with announcement number CN217907620U include a box assembly, wherein the box assembly includes a front cover assembly and a rear cover assembly, wherein the front cover assembly and the rear cover assembly enclose a liquid storage cavity, and a locking assembly, wherein the locking assembly is arranged on the front cover assembly and is used for installation with a cleaning device, and the filter assembly is located at the water inlet.

A hand grip ring is provided. When the touch button is pressed, the guide rod can be driven to move synchronously. When the guide rod moves, the hand grip ring can be extended outward from the body shell. At the same time, when the guide rod moves, the guide slot on its side and the clamping joint part at the end of the movable plug rod are located in the same straight line, the movable plug rod is reset and rebounded under the action of the built-in spring. The clamping joint part at the end of the movable plug rod after reset is inserted into the guide slot, thereby completing the position fixing of the guide rod after movement, avoiding the need for the user to keep pressing the touch button with his hand, and preventing the rebound force of the auxiliary spring from constantly exerting pressure on the finger; 2.

After the power guide rod moves, the bevel of the first pressing block can be used to squeeze the bevel of the second pressing block, so that the second pressing block and the locking pin move downward and retract into the interior of the fuselage shell, thereby releasing the fixing between the fuselage shell and the fuselage, making it easier to remove the fuselage shell from the fuselage later; 3. A drag-reducing ball is provided. When the locking pin moves on the body shell, the drag-reducing ball on the side of the locking pin rolls on the body shell, thereby converting the sliding friction between the locking pin and the body shell into rolling friction, thereby reducing the overall resistance and reducing the force required for the finger to press the touch button.
