The working process of the sweeper is as follows:

under the normal work of the sweeper, the roller of the sweeper is in contact with the ground, the roller 4 is in an upward movement state, the vertical rod part 611 is driven to move upwards, the transverse rod part 612 also moves upwards at the moment, when the transverse rod part 612 moves upwards, the first end of the rotating strip 62 is pushed to move upwards, and at the moment, the second end of the rotating strip 62 drives the movable plate 5 to move downwards to a state of opening a flow channel. After the fan 2 is started, under the action of the fan, the mixed fluid of dust, liquid and the like is separated by the separating member, sewage is deposited in the chamber 30 of the separating member, and the separated airflow pushes the baffle plate 31 to open the air outlet 301, at this time, the airflow is discharged through the air outlet 331, the flow channel and the fan 2. When the sweeper finishes working, the fan stops working, and at the moment, the baffle 31 closes the air outlet 301 under the action of the torsion spring.

When the sweeper is toppled or lifted, the roller 4 is separated from the contact with the ground to be cleaned, the roller 4 moves downwards under the action of the third spring 41, at this time, the vertical rod part 611 and the horizontal rod part 612 are driven to move downwards to leave a gap with the first end of the rotating strip 62, then, the movable plate 5 and the second end of the rotating strip 62 can move upwards under the action of the second spring 7 to a state of blocking a flow channel, and the sewage in the chamber 30 is prevented from flowing into the fan 2 through the flow channel. In addition, when the separation module is taken out of the machine body 1 for cleaning, the flow channel is blocked, so that the sewage in the machine body 1 can not flow into the fan 2 through the flow channel.
