The transmission member 20 has a first position and a second position, and in the first position, the transmission member 20 drives the pin 10 to move to the ejection position to open the drain opening. When the driving member 20 is at the second position, the ejector rod 10 leaves the water outlet and falls back to the return position, so that the blocking structure in the water outlet blocks the water outlet again. The driving member 30 is in driving connection with the transmission member 20, and the driving member 30 is used for driving the transmission member 20 to move between the first position and the second position. The sensor 40 is electrically connected to the driving member 30, the sensor 40 is used for sensing the position of the driving member, and when the driving member 20 enters the first position and the second position, the sensor 40 sends a control signal to stop the driving member 30 from driving the driving member 20.

Specifically, before the robot enters the base station, the driving member 20 of the drainage mechanism is in the second position, and the push rod 10 is in the return position. When water in the water tank needs to be discharged, the robot moves to a base station, the water outlet is aligned to the ejector rod 10 of the water discharging mechanism, the driving piece 30 drives the driving piece 20 to move from the second position to the first position at the moment, when the driving piece 20 moves to the first position, the sensor 40 is triggered and sends a control signal, the driving piece 30 stops driving the driving piece 20 after receiving the control signal, damage caused by the fact that the driving piece 20 moves over the position is avoided, at the moment, the ejector rod 10 moves to the ejection position and ejects the blocking structure in the water outlet to open the water outlet, and water flows out of the water outlet. After the water is completely discharged, the driving part 30 drives the driving part 20 to move from the first position to the second position, when the driving part 20 moves to the second position, the sensor 40 is triggered again and sends out a control signal, the driving part 30 stops driving the driving part 20 after receiving the control signal, damage caused by the fact that the driving part 20 moves over is avoided, the ejector rod 10 falls back to the return position at the moment, the ejector rod leaves the water outlet, and the water outlet is sealed by the sealing structure in the water outlet again.

Further, referring to fig. 2 and 3, the sensor 40 is configured to emit a sensing light ray 43 to sense a position of the driving member 20, preferably, the sensor 40 may be an optical coupler sensor 40, for example, the sensor 40 is an opposite optical coupler sensor 40, the opposite optical coupler sensor 40 includes an emitting end 41 and a receiving end 42, the emitting end 41 is configured to emit the sensing light ray 43, the receiving end 42 is configured to receive the sensing light ray 43, and the receiving end 42 can send a control signal to control the driving member 30 to stop after receiving the sensing light ray 43. The emitting end 41 and the receiving end 42 are arranged on both sides of the transmission member 20, respectively.

Specifically, referring to fig. 2 and fig. 3, in the present embodiment, the transmission member 20 includes a head end 21 close to the top rod 10 and a tail end 22 far from the top rod 10, a first avoiding hole 23 is formed between the head end 21 and the tail end 22, and when the transmission member 20 moves between the first position and the second position, the transmission member 20 blocks the sensing light 43, at this time, the receiving end 42 cannot receive the sensing light 43, and the driving member 30 continuously drives the transmission member 20 to move.

When the driving member 20 moves to the first position, the tail end 22 of the driving member 20 moves out of the sensing range of the sensor 40, so that the driving member 20 cannot block the sensing light 43, at this time, the sensing light 43 passes through the side of the tail end 22 of the driving member 20, the receiver receiving end 42 receives the sensing light 43 to trigger the sensor 40 to send a control signal, the driving member 30 stops driving the driving member 20 after receiving the control signal, and at this time, the driving member 20 stops at the first position, so that the driving member 20 is prevented from moving excessively.

When the transmission member 20 is at the second position, the first avoiding hole 23 is just aligned with the sensing light 43 of the sensor 40, so that the transmission member 20 cannot block the sensing light 43, the sensing light 43 can pass through the first avoiding hole 23 to reach the receiving end 42, the receiving end 42 receives the sensing light 43 to trigger the sensor 40 to send a control signal, the driving member 30 stops driving the transmission member 20 after receiving the control signal, and the transmission member 20 stops at the second position, so that the transmission member 20 is prevented from moving too far.

When the transmission member 20 moves from the first position to the second position to release the position limitation of the push rod 10, the elastic member 14 releases the elastic potential energy to drive the push rod 10 to move from the push-out position to the return position. Understandably, in another embodiment, when the weight of the top rod 10 is larger than the friction force between the top rod 10 and the inner wall of the water outlet by balancing the top rod 10, the top rod 10 can automatically fall back to the return position from the ejection position by the self-gravity after the driving member 20 moves from the first position to the second position, and the elastic member 14 can be omitted.

It should be noted that the driving means 30 and the transmission member 20 may be driven in various manners, and are not limited to the manner in which the gear 31 is engaged with the rack portion 25. For example, in other embodiments, the driving member 30 may be an electric push rod or an air cylinder, through which the driving member 20 is driven to reciprocate between the first position and the second position; or the driving member 30 and the driving member 20 are driven by a screw nut mechanism, the driving member 30 is connected with the screw, and the driving member 20 is connected with the nut sleeved on the screw, so that the driving member 30 drives the screw to rotate, and the nut can drive the driving member 20 to reciprocate between the first position and the second position along the screw, which is not described herein again.

Referring to fig. 1, the push rod 10 is disposed on the elastic contact element 12 at one end of the rod portion 11 away from the first clamping portion 13, and when the push rod 10 is in the push-out position, the elastic contact element 12 extends into the drainage port to jack up the blocking structure in the drainage port, so that hard collision between the push rod and the blocking structure is avoided, and further damage to the push rod or the blocking structure is avoided. When the ejector rod 10 is at the return position, the elastic contact piece 12 leaves the water outlet, so that the blocking structure is released from the limit, and the blocking structure returns to the water outlet to block the water outlet again.
