The spring may be one, and the spring may be sleeved at one end of the connecting rod 51, at which time the other end of the connecting rod 51 may passively rotate, for example, the spring may abut the first blocking member 52, or the spring may abut the second blocking member 53. The springs may be at least two, and the two springs are respectively disposed at both ends of the link 51, and the two springs respectively abut against the first blocking piece 52 and the second blocking piece 53.

When the driving part 54 drives the ejector 55 to move upward, the link 51 may rotate in a first direction, so that the first blocking member 52 and the second blocking member 53 release the inlet 411 and the outlet 412, at this time, the elastic member 56 is compressed, and after the driving part 54 releases the power, or after the driving part 54 operates in a reverse direction, for example, when the motor rotates forward, the ejector 55 moves upward, and when the motor rotates backward, the driving part 54 may not be fixedly connected with the ejector 55, the link 51 is driven to rotate in a second direction by the driving force of the elastic member 56 to restore the original state, so that the ejector 55 is compressed to move downward, and thus the first blocking member 52 and the second blocking member 53 block the inlet 411 and the outlet 412.

For example, when the detection system 60 detects a change in the material of the working surface, the carpet is changed into the tile, and at this time, the control system 80 may control the driving system 30 to accelerate, and the control system 80 may also control the cleaning system 20 to accelerate.

The detection system 60 may be used to detect a change in a material of the surface to be cleaned, a change in a level of the surface to be cleaned, or a detection of dirt, etc., so that the detection system 60 may feed back to the control system 80 to control an operation state of the cleaning robot, for example, when the detection system 60 detects that the surface to be cleaned is dirty, the control system 80 may control the cleaning robot to slow down, so as to ensure that the cleaning system 20 can clean the surface to be cleaned better; alternatively, when the detection system 60 detects that the surface to be cleaned is a floor, the control system 80 may control the water pump 24 to increase the flow rate of the cleaning liquid in the liquid supply portion 22 into the cleaning head 21 and the auxiliary cleaning head 23, thereby ensuring reliable cleaning of the floor; alternatively, the control system 80 may adjust the walking path and the cleaning mode of the cleaning robot according to the information fed back by the detection system 60, for example, when the detection system 60 is in an extended state, the detection system 60 may be located in front of the machine body 10, so that the detection system 60 may early determine the state of the surface to be cleaned, and thus feed back the state to the control system 80, so that the control system 80 may adjust the walking path and the cleaning mode of the cleaning robot according to the information fed back by the detection system 60, the detection system 60 may early detect a change in the floor material, for example, when the floor is changed from the floor to the carpet, the detection system 60 may provide relevant information to the control system 80 in real time, so that the control system 80 may control the walking direction or the cleaning mode of the cleaning robot in time, for example, when the floor is changed from the carpet to the carpet, or may control the cleaning robot to reduce the liquid supply amount to the cleaning head 21 and the auxiliary cleaning head 23 when the floor is changed from the floor to the carpet.

In the embodiment of the present disclosure, the detection system 60 may be plural, so that the detection range of the detection system 60 may be effectively enlarged, thereby precisely assisting the working state of the cleaning system 20 or the driving system 30. The number of detection systems 60 may be two, and as shown in fig. 1, the two detection systems 60 may be disposed at two corner positions of the forward portion 12, respectively.
