Referring to fig. 9, as a modification of the above embodiment, the second pre-tightening mechanism 430 further includes a first cam 433 and a second cam 434, where the first cam 433 is connected to a rotating shaft of the first discharging roller 410, and the second cam 434 is connected to a rotating shaft of the second discharging roller 420, when the two rotate to the profile with the increased diameter and abut against each other, the second cam 434 can push the first cam 433 to move towards a direction away from the first discharging roller 410, that is, the second discharging roller 420 moves a set distance towards a direction away from the first discharging roller 410 against the action of the first elastic member 432, so as to increase a gap between the first discharging roller 410 and the second discharging roller 420, so that the protection pad enters between the first discharging roller 410 and the second discharging roller 420 or drops from between the first discharging roller 410 and the second discharging roller 420. In a specific implementation, the first cam 433 or the second cam 434 may be configured as a semicircular wheel, or both the first cam 433 and the second cam 434 are semicircular wheels. Therefore, the first cam 433 can intermittently eject the second cam 434 along with the continuous rotation of the first discharging roller 410, and after the second cam 434 leaves the first cam 433, the second discharging roller 420 returns to the original position under the action of the first elastic member 432 and keeps pressing against the first discharging roller 410, so that the first discharging roller 410 and the second discharging roller 420 can be intermittently opened and pressed.

Referring to fig. 9, in the above embodiment, the second cam 434 may further connect the positioning wire 435 and the second elastic member 436 for preventing the second cam 434 from being misaligned. Specifically, a side of the second cam 434, which is away from the first cam 433, is provided with a through hole 438 for connecting the positioning line 435, one end of the positioning line 435 is connected to the through hole 438, the other end of the positioning line 435 is connected to the second elastic member 436, the second elastic member 436 is connected to the case 100, the positioning line 435 passes around the fixed pulley 437 which is flush with the through hole 438, the convex profile of the second cam 434 is located above, and due to the positioning line 435, the fixed pulley 437 and the elastic member 234, the second cam 434 can rotate within a small range in its position, the convex profile of the second cam 434 is maintained above the rotating shaft of the second discharging roller 420 and cannot rotate below, and the second cam 434 is prevented from rotating below the rotating shaft of the second discharging roller 420 and being staggered from jacking up of the second cam 434. Accordingly, the first cam 433 intermittently ejects the second cam 434 as the first discharging roller 410 continues to rotate.

Referring to fig. 1 to 3, in some embodiments, the washing machine further includes a drying mechanism 600 for continuously drying the washed protection pad. The drying mechanism 600 includes a receiving member 610 and a dryer 620, the receiving member 610 is connected to the cabinet 100 and located below the outlet 130 for receiving the protection pad sent out of the cabinet 100 from the outlet 130, and the dryer 620 is used for drying the protection pad on the receiving member 610. Specifically, the receiving member 610 is connected to the outlet 130 at one side, and inclined downward at the other side, so as to receive the protection pad discharged from the discharging assembly 400, and a blower is used as the dryer 620 and disposed at the other side of the receiving member 610, and the receiving member 610 has a mesh structure, so that air blown by the blower can pass through the mesh of the receiving member 610 to air-dry the protection pad on the receiving member 610.

Referring to fig. 2, as a modification of the above embodiment, a shield 630 is disposed below the chassis 100, the fan is installed in the shield 630, an air outlet 631 is formed in a side of the shield 630 facing the receptacle 610, and an air deflector 640 is connected to the air outlet 631, so that the air outlet 631 extends to the receptacle 610 to form an air duct, and an air flow generated by the fan is directly blown to the protection pad on the receptacle 610 through the air outlet 631 and the air deflector 640, thereby improving the air drying efficiency.

Referring to fig. 1 and 2, in some embodiments, the cleaning machine further includes a dirt collection tank 700, the dirt collection tank 700 is disposed below the socket 610, the dirt collection tank 700 has a notch 710 and a dirt discharge outlet 720, the notch 710 faces the socket 610 and the outlet 130 of the machine case 100, and the dirt collection tank 700 is used for collecting dirt and sewage generated in the cleaning process and discharging the dirt and sewage from the dirt discharge outlet 720.

Referring to fig. 1 and 2, the cleaning machine of the above embodiment may further include a traveling mechanism 800, the traveling mechanism 800 includes a frame 810 and traveling wheels 820, the case 100 is disposed above the frame 810, the drying mechanism 600 may be connected to the case 100 and/or the frame 810, and the traveling wheels 820 are disposed at the bottom of the frame 810, so that the cleaning machine may be conveniently moved as a whole, and the convenience of use may be improved.
