Cleaning dust return system for floor washing machine

Abstract

The invention discloses a cleaning dust return system for a floor washing machine in the technical field of floor washing machines. The cleaning dust return system comprises a rack, a sweeping brush, a sweeping brush driving mechanism, a dust return bin, two seal assemblies, a movable base, a first rotating shaft, a withdrawable recovery bin, a movable limiting seat, a second rotating shaft, and a locking assembly. Each seal assembly comprises a sealing door, a door hinge shaft, and a door locking member for locking the position of the sealing door. One end of the sealing door is rotatably mounted on the frame by means of the door hinge shaft. The sweeping brush is located in the dust return bin. The withdrawable recovery bin is placed on the movable base. The movable limiting seat is locked on the rack through the locking assembly, and just presses against the movable base when locked by the locking assembly. When the sealing door is locked by the door locking member, the free end of the sealing door just props against the movable base. The power consumption is significantly reduced, and dust pouring is facilitated.

Description

technical field [0001] The invention relates to the technical field of floor washing machines, in particular to a cleaning and dust return system for floor washing machines. Background technique [0002] At present, many scrubbers are equipped with dry sweeping mechanisms. The most widely used technical solution is as follows: use the high-speed rotation of the sweeping brush to sweep the dust on the ground to the negative pressure suction port, and use the negative pressure source to suck the dust away. Such technical means have the following disadvantages: first, the power consumption is large, it is necessary to drive the sweeping brush to rotate at a high speed, and the fan is also required to rotate continuously, wherein the energy consumed by the fan operation accounts for a large proportion; second, it is inconvenient to discharge dust; Its three, sweeping brush can cause dust to fly when rotating at high speed. Contents of the invention [0003] The object of the ...
