At the same time, through the operation of the vacuum cleaner, suction is generated at the dust hood in conjunction with the dust collection pipe, and dust collection and cleaning operations are performed on the drawn position.

[0014] As a further technical solution of the present invention, a dust box is installed on the upper part of the splicing box. The inner side of one end of the dust box is a hollow structure, and several groups of dust filter pads are fixedly installed on the inner side of the dust box. When the vacuum cleaner is running, the dust swept from the ground can be sucked into the dust box for collection, and the dust filter pads play a dust filtering role.

[0015] As a further technical solution of the present invention, the bottom of the mobile base and the splicing angle plate are both provided with caster structures, the inner side of the mobile base is movably installed with a pin, and the upper part of the mobile base is movably installed with a push block for driving the pin, one side of the splicing angle plate is provided with a slot for cooperating with the pin, and the other side of the splicing angle plate is fixedly installed with a docking card, and the inner side of the mobile base is provided with a slot for cooperating with the docking card.
