[0039] The clean water area is used to store clean water and is equipped with a clean water outlet pipe;

[0040] The sewage area is used to store sewage discharged from the equipment and is equipped with a sewage inlet pipe;

[0041] a first clean water pump, the water inlet of which is connected to the clean water outlet pipe;

[0042] a first sewage pump, the water outlet of which is connected to the sewage inlet pipe;

[0043] The male end connector is used to realize the circuit and water connection between the water tank and the equipment. The male end connector is provided with a first circuit connection terminal, a second circuit connection terminal, a first water channel connection terminal and a second water channel connection terminal, which are respectively used to connect the power input ends of the first clean water pump and the first sewage pump through cables, and to connect the water outlet of the first clean water pump and the water inlet of the first sewage pump through water pipes.

[0044] In this embodiment, a water circulation filtration system can be set up on the water tank or equipment, with a clean water inlet pipe provided in the clean water area and a sewage outlet pipe provided in the sewage area. In this case, the water tank also includes:

[0045] A water pump, the water inlet of which is connected to the sewage outlet pipe through a water pipe, and the water outlet of which is connected to the water inlet of the water circulation filtration system through a water pipe;

[0046] A second clean water pump, whose water inlet is connected to the water outlet of the water circulation filtration system through a water pipe, and whose water outlet is connected to the clean water inlet pipe through a water pipe;

[0047] The male connector is equipped with a third circuit connection terminal, a fourth circuit connection terminal, a third waterway connection terminal, and a fourth waterway connection terminal. These terminals are used to connect to the power input terminals of the water pump and the second sewage pump via cables. The water pump and the second sewage pump can be connected directly to the water circulation and filtration system, or they can be connected to the water circulation and filtration system separately through the third and fourth waterway connection terminals on the male connector.

[0048] As shown in Figures 1 and 2, the above water tank is applied to a cleaning robot workstation. That is, a cleaning robot workstation water tank mainly consists of a sewage tank 1, a clean water tank 2, and a male end connector. The sewage tank 1 is equipped with:

[0049] The sewage inlet pipe 11 provides a sewage discharge channel for the cleaning robot, that is, the sewage of the robot itself is directly discharged to the sewage tank 1 in the water tank of the cleaning robot workstation through the sewage inlet pipe 11;

[0050] The sewage outlet pipe 12 is used as a sewage filtering channel. The sewage is pumped out through the sewage outlet pipe by the workstation sewage pump and filtered through the workstation filtration system / filter. After filtering, the sewage becomes clean water and is recycled into the clean water tank 2;

[0051] Sewage tank water level gauge 13, used to determine the sewage status of the sewage tank;

[0052] The sewage drain pipe 14 is used to directly discharge the sewage in the sewage tank.

[0053] Clean water tank 2 is equipped with:

[0054] The clean water inlet pipe 21 is the clean water inlet channel obtained after sewage filtration, which has been described in the sewage tank part above;

[0055] The clean water outlet pipe 22 provides a clean water supply channel for the cleaning robot. The clean water is pumped by the clean water pump of the workstation through the clean water outlet pipe 2 to pump the clean water in the clean water tank of the cleaning robot workstation into the clean water tank of the robot;

[0056] A clean water tank water level gauge 21 is used to determine the clean water status of the clean water tank;

[0057] The clean water drain pipe 14 is used to directly drain the clean water in the clean water tank.

[0058] The male connector, serving as a water and electrical circuit docking connector, is installed within the box body 5, located on the side wall of the water tank's outer housing 4, for easy insertion and removal. The clean water inlet and outlet pipes serve as the clean water inlet channel after sewage filtration, while the clean water outlet pipe is the robot's clean water supply channel. Clean water is pumped through the workstation's clean water pump and then pumped through the clean water outlet pipe to the robot's clean water tank. This repeated cycle enables self-sufficient water utilization in scenarios where on-site modification is difficult or unacceptable, ensuring the robot's full coverage of normal operations.

[0059] The workstation water tank is also designed with a water tank cover 6 and a water tank cover support rod 61, which facilitates the support rod to limit the support when opening the cover to prevent the water tank cover from colliding. An adjustable push handle 7 is also designed, which can be adjusted according to the actual operating comfort. At the same time, brake casters 8 are installed at the bottom of the water tank to ensure that it is easy to push and load during transportation, and the brake limiter prevents the water tank from moving after placement.

[0060] Example 2

[0061] As shown in FIG3 , this embodiment proposes a water tank that is similar in structure and function to the water tank in the first embodiment and is also provided with a sewage tank, a clean water tank, an outer box body, a male connector 3, etc. The main difference is that the functional areas on the water tank of this embodiment are distributed differently, and a storage backpack for accommodating all water pumps is provided in the water tank. The storage backpack is not shown in FIG3 . The storage backpack can be provided outside the outer box body or a dedicated installation area can be provided inside the outer box body. The storage backpack is used to store all water pumps internally, and is provided with an inlet and outlet to facilitate the connection of all water pumps to the sewage tank and the clean water tank, shorten the water pipes connected to the male connector, and make the water tank more beautiful and practical.

[0062] As shown in Figures 4 to 6, this is a specific example of the male connector 3. This connector plays a key role in connecting the water and circuits between the cleaning robot and the workstation water tank; clean sewage, drainage and filtration all need to be transferred through this connector; and electrical communications also need to be transferred through this connector.

[0063] As shown in Figure 4, the male connector 3 serves as a male connector and is used to connect to the female connector 100 provided on the cleaning robot. The male connector 3 includes a mounting member 30, a circuit connection terminal 31, and a waterway connector. The entire male connector is fixedly mounted in the box body 5 via the mounting member 30. The waterway connector includes four waterway connection terminals 32. One end of the circuit connection terminal 31 and one end of each waterway connection terminal 32 are fixed via the mounting member 30, forming the various fixed terminals of the male connector; the other end of the circuit connection terminal 31 is connected to the power supply via a cable, and the other end of each waterway connection terminal 32 is connected to the sewage tank 1 or the clean water tank 2 via a water pipe, respectively forming the sewage inlet pipe 11, sewage outlet pipe 12, clean water inlet pipe 21, and clean water outlet pipe 22. A corresponding sewage pump or clean water pump is provided on each pipe.

[0064] As shown in Figures 5 and 6, the mounting member 30 is provided with an arc-shaped stopper 33 that surrounds the fixed terminals of the male connector. This arc-shaped stopper 33 defines an opening 331 for positioning, and a locking groove 34 is provided on its outer wall. The female connector on the cleaning robot includes an arc-shaped docking member 101 that docks with the arc-shaped stopper 33. This arc-shaped docking member 101 is equipped with pluggable terminals that dock with the fixed terminals, and positioning protrusions 102 that dock with the opening 331. Locks 103 are provided on its outer wall that correspond to the locking grooves 34. This locking structure secures the male and female connectors together, enabling a quick connection.

[0065] The plug-in terminals correspond to the fixed terminals, including water connection terminals and circuit connection heads. The tails of the corresponding plug-in terminals are connected to the fresh water inlet and sewage inlet of the cleaning robot through water pipes, and are connected to the charging port of the cleaning robot through cables. The water pipes and cables at the tails of all plug-in terminals are bound together by setting pipe sleeves, forming a water-electricity quick connection joint that is easy to operate and integrates water and electricity connection functions.
