An exhaust fan located in the exhaust pipe is installed at the output end of the fan motor through a rotating shaft. The base is provided with an air inlet channel, and the air inlet channel is connected with the exhaust pipe. The air inlet channel extends to the bottom edge of the base and is provided with a wide opening. A gasket is fixedly provided on the outer wall of the exhaust pipe, and a snap-in bracket is installed on the gasket. A filter layer is fixedly provided on the snap-in bracket. A circle of wall of the side wall below the filter layer is a ventilation wall with holes.

[0006] Preferably, the arc-shaped cover is high at the top and low at the edge, a rotating handle is fixedly provided on the top of the arc-shaped cover, and a sealing ring is fixedly provided on the inner wall of the side wall below the arc-shaped cover.

[0007] Preferably, the wide opening faces the ground and the outside of the base, the air inlet passage surrounds the base, and the separated parts are fixedly connected inside by a bracket.

[0008] Preferably, a dust filter is installed on the filter layer.

[0009] The beneficial effects of the utility model are as follows: the structure is simple, and the dust in the clean room is absorbed by exhausting air. The exhaust port is located at the bottom, so the ground and air can be cleaned during movement, and the filter element can be replaced conveniently. The utility model has strong practicality, as follows:

[0010] (1) The utility model is provided with a base, and the base is moved by a driving seat. When moving, the driving motor drives the driving wheel to move, and the rotating seat controls the rotation of the steering wheel to control the movement direction of the base. During the movement of the base, the exhaust fan in the exhaust duct exhausts air, and its wide exhaust opening is close to the ground, facing the ground and the outside, so as to suck the dust on the ground and in the air. When there is no need to clean the ground, the device can be placed in a corner and used as an air filter.

[0011] (2) The utility model is provided with an exhaust duct. When the exhaust duct draws air, the airflow rises from the exhaust duct and hits the arc cover. Under the action of the arc cover, the airflow is separated to the surroundings and flows back to the space between the outer wall of the exhaust duct and the inner wall of the side wall. After being filtered by the filter layer, it is discharged from the ventilation wall. After being used for a period of time, the arc cover is rotated and removed by rotating the handle, and the filter layer on it is removed and replaced by removing the bracket.
