Moreover, the torsion spring is matched with the baffle 421, so that the baffle 421 rotates stably and reliably.
In this embodiment, when the scrubber is not in operation, the baffle 421 keeps close contact with the inner wall of the box 41 under the elastic force of the torsion spring, so that the baffle 421 closes the air inlet 411. When the floor cleaning machine works, the suction fan 3 starts to work, and under the suction action of the suction fan 3, the baffle 421 overcomes the elasticity of the torsion spring and rotates towards the direction far away from the air inlet 411 to open the air inlet 411, so that sewage or solid particles enter the inner cavity 410 of the box body 41 from the air inlet 411, and the collection of the sewage or the solid particles is realized.
As an embodiment of the present invention, the torsion spring includes two torsion spring bodies 4220 disposed at an interval, a first torsion arm 4221 and a second torsion arm 4222 respectively connecting the two torsion spring bodies 4220, the two torsion spring bodies 4220 are sleeved on the rotation shaft 4211, the first torsion arm 4221 is connected with the baffle 421, and the second torsion arm 4222 is connected with the box 41. The two torsion spring main bodies 4220 are sleeved on the rotating shaft 4211 at intervals, and stress is exerted on the two torsion spring main bodies 4220 at the same time, so that the stress on the torsion springs is more uniform.
In this embodiment, when the flap 421 covers the air inlet 411, the first torsion arm 4221 and the second torsion arm 4222 are kept in an outward-opening state, and the flap 421 receives the pushing force of the first torsion arm 4221, so that the flap 421 is in close contact with the inner wall of the box 41, thereby closing the air inlet 411; when the flap 421 is subjected to the suction force of the suction fan 3 to open the air inlet 411, the flap 421 rotates and presses the first torsion arm 4221, so that the first torsion arm 4221 and the second torsion arm 4222 approach each other, and the flap 421 reversely rotates under the restoring force of the first torsion arm 4221 until the suction fan 3 stops working, so that the flap 421 realizes the closing of the air inlet 411 again.
As an embodiment of the present invention, the first torsion arm 4221 has an open ring structure or a closed ring structure. Wherein, the ring shape can be square, round or polygonal. Because the first torsion arm 4221 is arranged in a ring structure, the contact area between the first torsion arm 4221 and the baffle 421 can be increased, so that the baffle 421 is uniformly stressed, the rotation of the baffle 421 is more stable, and the sealing effect of the baffle 421 on the air inlet 411 is better.
As an embodiment of the present invention, the baffle 421 is provided with a groove 4210 engaged with the first torsion arm 4221, the first torsion arm 4221 is embedded in the groove 4210, and the first torsion arm 4221 is engaged with the groove 4210 to stably fix the first torsion arm 4221 on the baffle 421, thereby preventing the first torsion arm 4221 from being separated from the baffle 421.

In this embodiment, when the scrubber is not in operation, the baffle 421 is kept in close contact with the inner wall of the tank 41 under the action of the elastic member 422, so that the baffle 421 closes the air inlet 411. When the floor cleaning machine is working, the suction fan 3 starts working, and under the suction action of the suction fan 3, the baffle 421 overcomes the acting force of the elastic member 422 and moves in parallel towards the direction far away from the air inlet 411 to open the air inlet 411, so that sewage or solid particles enter the inner cavity 410 from the air inlet 411, and the collection of the sewage or the solid particles is realized. When the floor washing machine stops working, the baffle 421 keeps close contact with the inner wall of the box 41 under the action of the elastic member 422, so that the baffle 421 closes the air inlet 411.
As an embodiment of the present invention, the elastic member 422 is a spring connecting the baffle 421 and the box 41.
When the floor washing machine works, under the action of suction force of the suction fan 3, the baffle 421 moves in parallel towards the direction away from the air inlet 411 to open the air inlet 411, and meanwhile, the baffle 421 stretches the spring in the movement process, so that sewage or solid particles can enter the sewage tank from the air inlet 411, and the sewage or solid particles are collected continuously. After the floor washing machine stops working, the suction force of the suction fan 3 disappears, at this time, under the action of the restoring force of the spring, the spring drives the baffle 421 to move in parallel towards the direction close to the air inlet 411 so as to close the air inlet 411 again, and the sewage or solid particles in the sewage tank are prevented from overflowing from the air inlet 411.
As an embodiment of the present invention, the baffle plate assembly 42 further includes:
and a sealing ring 424 arranged on the baffle 421, wherein the baffle 421 contacts with the inner wall of the box 41 through the sealing ring 424 to close the air inlet 411.
