The dust extraction unit comprises a dust extraction fan (not shown) and a dust collection port 13, a dust outlet 25 is correspondingly arranged on the sweeping robot 2, and the dust extraction fan can form strong suction during working, so that dust extraction of the sweeping robot 2 by the central workstation 1 is realized.

In this embodiment, when the sweeping robot 2 and the central workstation 1 are charged and docked for dust extraction, the housing 11 of the central workstation 1 includes a docking platform 10 that is docked with the sweeping robot 2, and the docking platform 10 is provided with a dust suction port 13, a limiting structure 14, a guiding structure 15 and a charging terminal 12. When the sweeping robot 2 is docked with the central workstation 1, the sweeping robot 2 travels on the docking platform 10 along the guide structure 15, and when the sweeping robot reaches the docking position, the limiting structure 14 limits the movement of the traveling wheels 21, so that the dust outlet 25 is docked with the dust suction port 13, and the power receiving terminal is docked with the charging terminal 12.

Alternatively, the docking platform 10 has a docking surface 100 for disposing the dust suction port 13 and the charging terminal 12, and inclined surfaces 101 disposed at both sides of the docking surface 100, the inclined surfaces 101 at both sides being convenient for the traveling wheels 21 to travel thereon. Taking one of the inclined planes 101 as an example, the inclined plane 101 includes a first inclined plane 1011 and a second inclined plane 1012, wherein it is defined that when the sweeping robot 2 is docked, the first inclined plane 1011 is driven first, and then the second inclined plane 1012 is driven, that is, the first inclined plane 1011 and the second inclined plane 1012 are sequentially arranged along the docking driving direction of the sweeping robot 2.

Optionally, limit structure 14 sets up in the junction of first inclined plane 1011 and second inclined plane 1012, and when robot 2 of sweeping the floor traveles to this junction, limit structure 14 restricts walking wheel 21's removal, and at this moment, charging terminal 12 and dust absorption mouth 13 are configured into and dock with receiving terminal and dust outlet 25 respectively, have both played spacing effect, can play the effect of assistance-localization real-time again.

In this embodiment, the limiting structure 14 is of a step structure, and the setting of the limiting structure 14 enables the height of the first inclined surface 1011 at the joint to be higher than the height of the second inclined surface 1012 at the joint, so that by adopting the design mode, the walking wheel 21 can be abutted, and the walking wheel 21 is prevented from sliding down backwards from the inclined surface 101.

Optionally, the limiting structure 14 may also adopt a groove structure to engage the first inclined surface 1011 and the second inclined surface 1012, and when the road wheel 21 travels to the engagement, the road wheel 21 may be jammed in the groove structure.

Optionally, one or more anti-slip belts 1013 are disposed on the first inclined plane 1011, and the second inclined plane 1012 can be selectively disposed, and the moving speed of the traveling wheels 21 on the first inclined plane 1011 can be reduced by disposing the anti-slip belts 1013, so that the sweeping robot 2 is prevented from colliding with the central workstation 1 during docking, and the sweeping robot 2 is prevented from colliding with the ground due to too high speed during exiting from the central workstation 1 during docking.

In this embodiment, the guide structure 15 is disposed between the docking surface 100 and the inclined surface 101, and the traveling wheel 21 moves on the first inclined surface 1011 along the guide structure 15 toward the second inclined surface 1012 to accurately reach the docking position.

Optionally, the guiding structure 15 comprises two guiding edges, and the height of the guiding edges is higher than the first inclined surface 1011 and the second inclined surface 1012. And the distance between the two guide edges is less than or equal to the distance between the inner side surfaces of the two travelling wheels 21. As shown in fig. 3, when the sweeping robot 2 performs docking, the guiding edge uses the inner side surface of the traveling wheel 21 as a guiding object to guide the sweeping robot 2 to complete docking according to a correct direction, so as to avoid the phenomenon that the sweeping robot 2 tilts when climbing the inclined plane 101, which causes inaccurate docking.

At present, the dust suction port 13 on the central workstation 1 mostly adopts a plastic dust port structure, in the related art, when the sweeping robot 2 is back-filled and butted, the plastic dust port can rub against the plastic dust port, a head tilting phenomenon is generated, the sealing performance between the plastic dust port and the robot dust port is not good, and dust is easy to leak from the dust suction port 13 of the central workstation 1 and the dust outlet 25 of the sweeping robot 2 in a dust pumping process.
