After the surface cleaning machine 100 has finished performing the surface cleaning operation, the machine may dock onto the base waste station 500 and dock with the base waste station 500; after docking is complete, operations such as draining, charging, and replenishing cleaning fluid to the surface cleaning machine 100 may be performed.

As shown in fig. 13-14, after the surface cleaning machine 100 is docked with the base waste station 500, the interfaces on the surface cleaning machine 100 are interconnected with the interfaces on the base waste station 500 as follows:

the first outlet 584 and the first inlet 2115 are connected to each other, and the cleaning liquid in the liquid reservoir 581 can be supplemented to the liquid supply tank 25 by turning on the second pump 583.

The second outlet 586 and the second inlet 2653 are connected together, and the third pump 587 is turned on, so that the cleaning liquid in the liquid container 581 can be supplied to the liquid sprayer 2654, thereby realizing the flushing of the inner wall of the recycling chamber 261.

The charging interface 2116 of the surface cleaning machine 100 is electrically connected to the charging interface 62 of the waste collection station 500, and the electric energy introduced through the electrical plug is converted into an electric energy acceptable by the battery pack 24 and supplemented to the battery pack 24 by the power supply circuit 61 and the charging management circuit 294, so as to charge the battery pack 24

The second signal transmission interface 63 is in signal communication with the first signal transmission interface 2117 to establish signal communication between the surface cleaning machine 100 and the base station 500, thereby facilitating information exchange between the second controller 501 and the first controller 28.

The drain cover 267 on the surface cleaning machine 100 is adjacent to the door 551 on the waste base 500 and the moving block 571 is adjacent to the unlock button 2610.

Referring to fig. 15-16, the door motor 552 on the base waste station 500 is activated to rotate the door 551 in a direction to open the discharge chamber 543 until the inlet end 541 of the discharge flow path 54 is opened, i.e., the discharge flow path 54 is opened.

Starting a moving block motor 572 on the pollution discharge base station 500, enabling a moving block 571 to be driven to move to an unlocking button 2610 and trigger the unlocking button 2610 to unlock, and disconnecting the first locking hook 268 and the second locking hook 2674; after the first and second locking hooks 268 and 2674 are disengaged, the drain cover 267 automatically opens under the action of the torsion spring 269, and the liquid in the waste recovery tank 26 will be able to flow under gravity into the drain flow path 54 and finally drain to the sewer.

After the door 551 and the drain cover 267 are both opened, the door motor 552 of the drainage base station 500 is started to rotate the door 551 in a direction to close the inlet end 541, and the door 551 pushes the drain cover 267 to move towards the drainage port 5611 while rotating, so that the drain cover 267 is closed while the drain chamber 543 is closed; that is, the door motor 522 moves in a direction to actuate the door 551 to close the entrance end 541, and can simultaneously provide a driving power to the discharge cover 267 to close the soil outlet 5611. In other embodiments, the simultaneous closing of the drain cover of the surface cleaning machine may be performed without the use of a door motor, but rather may be performed by providing a separate drain cover closing mechanism.

Based on the above described relationship between the surface cleaning machine and the docking station, the surface cleaning machine 100 can automatically perform the operations of soil discharge, cleaning, water replenishment, etc. after being docked with the docking station 500 after use, without manually re-cleaning the soil solution recovery vessel or replenishing the fluid supply vessel with cleaning solution, which greatly reduces the burden on the operator to use the surface cleaning machine.
