The middle body 233 is provided with a radially extending protrusion 234, and the first end portion 51 is sleeved on the middle body 233 and located between the upper sealing ring 231 and the protrusion 234.

Further, the distance between the protrusion 234 and the lower seal ring 232 along the longitudinal direction is h1, the difference between the large diameter and the small diameter of the cam 4 is l1, and h1 is not less than l 1.

The movable bracket 5 includes an abutting portion 52 abutting against the cam and a connecting portion 53 connecting the abutting portion 52 and the first end portion 51, and the upper case 21 is provided with a connecting hole through which the connecting portion 53 is inserted.

Still be equipped with air exit 26 on the base 13, sealing member 23, 23 ' are including locating the second sealing member 23 ' of air exit 26, movable support 5 still include with the relative second tip 54 that sets up of first tip 51, second tip 54 cover is located on the second sealing member 23 '. As for the connection and position relationship of the second sealing member 23 and the air outlet 26, and the connection manner of the second end portion 54 and the second sealing member 23', the relationship of the first end portion 51, the first sealing member 23 and the dust exhaust port 22 can be referred to.

The movable bracket 5 is lifted or lowered by the cam 4, and the two sealing members 23 and 23' at the two ends are lifted or lowered simultaneously.

In this embodiment, the cam 4 is provided with a center hole, and the cam 4 is sleeved on the output shaft 31 of the motor through the center hole, but in other embodiments, a speed reduction mechanism may be provided between the cam 4 and the motor output shaft 31.

Preferably, a charging module is further disposed in the maintenance station 100, the motor 3 is electrically connected to the charging module, and the power of the motor 3 is supplied from the power supply module of the base 13 of the maintenance station 100. Further, the sweeping robot 6 comprises a driving module, and the driving module is in communication connection with the motor 3.
