Patent-family-91337401

A cleaning device is provided that includes a body, a collection tank, a suspension bracket, and a locking mechanism. The body defines a mounting location. The collecting box is used for containing wastes, and a hanging groove is arranged at the front part of the collecting box. The suspension bracket is arranged at the installation position. The hanging groove is used for sitting on the hanging bracket, so that the front part of the collecting box is hung on the hanging bracket. The locking mechanism is used for locking the rear part of the collecting box to the machine body. When the locking mechanism is in the locked state and the suspension groove is seated to the suspension bracket, the collection box is held in the installed position, and the suspension groove is supported by the suspension bracket. When the locking mechanism is in the unlocked state and the hanging slot is clear of the hanging bracket, the machine body and the collection box can be separated from each other. Thus, the cleaning device has high reliability.
