When the case cover 20 needs to be separated from the first opening 121, the connecting piece 232 can be moved in the mounting groove 221, so that the connecting piece 232 moves towards the limiting wall 222 to drive the free end 2322 to be separated from the fixing groove 1021, so that the free end 2322 is separated from the fixing groove 1021. By such arrangement, the engagement of the connecting member 232, the elastic member 231 and the limiting wall 222 enables the cover 20 to be quickly covered on the first opening 121 or separated from the first opening 121.

Referring to fig. 5 and fig. 6 again, fig. 6 is a working state diagram of a connector of a shrinkage assembly according to an embodiment of the utility model. In some embodiments, the upper cover 21 is provided with a second opening 211, the second opening 211 corresponds to the mounting groove 221, and the retraction assembly 23 is exposed to the outside air through the second opening 211. Specifically, the connecting member 232 may be exposed to the outside air through the second opening 211, and the upper cover 21 is adapted to the bottom cover 22. Wherein the connection member 232 is movably installed in the installation groove 221. When the connector 232 is moved, the user can directly contact the connector 232 through the second opening 211 and apply a pushing force to the connector 232, at this time, the elastic member 231 is compressed under force, the free end 2322 is far away from the fixing slot 1021, and the cover 20 can be separated from the first opening 121. After the user does not apply the pushing force to the connecting member 232, the elastic member 231 returns to the original state to drive the free end 2322 to approach the fixing slot 1021, so that the free end 2322 is connected with the fixing slot 1021, and the cover 20 can be covered on the first opening 121. With this arrangement, when the user needs to cover the cover 20 on the first opening 121 or separate from the first opening 121, a pushing force can be directly applied to the link 232 through the second opening 211 to move the link 232.

The gasket 24 is movable with the cover 20. When the cover 20 is disposed over the first opening 121, a gap may exist between the cover 20 and the second sidewall 102.

One side of the gasket 24 is closely attached to the outer peripheral side of the cover 20, and the other side is closely attached to the second side wall 102. By providing the gasket 24 on the outer peripheral side of the cover 20, the cover 20 is tightly coupled to the first opening 121 after the cover 20 is covered with the first opening 121, so that a closed space is formed in the second accommodating chamber 12. When the second accommodating chamber 12 stores the sewage, the sealing ring 24 can prevent the sewage from flowing out through the gap between the cover 20 and the second sidewall 102, and can prevent the peculiar smell of the sewage from drifting into the outside air.

Referring to fig. 7, fig. 7 is an exploded view of a detection assembly according to an embodiment of the utility model. In some embodiments, the case cover 20 further includes a detection assembly 25, the detection assembly 25 including a detection plate 251, a detection pole piece 252, an adapter plate 253, and pins 254; the detection plate 251 is mounted to the case cover 20; the detecting pole piece 252 is mounted on the detecting plate 251, and the detecting pole piece 252 faces the second accommodating cavity 12; the adapter plate 253 is electrically connected with the detection plate 251; one end of the pin 254 is electrically connected to the adapter plate 253, and the other end is electrically connected to an external host.

The detecting pole piece 252 is connected with the detecting plate 251, and the detecting pole piece 252 faces the second accommodating cavity 12 and is used for detecting the sewage in the second accommodating cavity 12. When the water level rises to contact the detecting pole piece 252 due to excessive water storage in the second accommodating chamber 12, a water level detecting circuit of the detecting assembly 25 is turned on. The adapter plate 253 is electrically connected with the detection plate 251, and the pins 254 on the adapter plate 253 are electrically connected with an external host. When the second accommodating chamber 12 is full of water, the circuit for detecting the water level of the detecting assembly 25 is turned on, and the circuit between the pin 254 and the external host is turned on. The external host stops working after receiving the signal, and the second accommodating cavity 12 no longer collects sewage. By such an arrangement, it is possible to perform monitoring of whether or not the amount of sewage in the second accommodation chamber 12 is excessive, and to prevent the excessive amount of sewage from overflowing the second accommodation chamber 12.

The external host may be a control system of the cleaning robot 200.

Referring to fig. 8, fig. 8 is an exploded view of a cleaning robot according to an embodiment of the utility model. Another embodiment of the present utility model provides a cleaning robot 200 including the water tank assembly 100 described above. When it is necessary to preserve fresh water and contaminated water inside the cleaning robot 200, the tank 10 may be installed inside the cleaning robot 200. The tank 10 includes a first accommodating chamber 11 and a second accommodating chamber 12, wherein the first accommodating chamber 11 can be used for storing clean water, and the second accommodating chamber 12 can be used for collecting sewage. The first accommodating cavity 11 and the second accommodating cavity 12 are arranged in a separated mode, so that clean water and sewage cannot circulate mutually. Through such a setting, the first accommodation chamber 11 and the second accommodation chamber 12 are simultaneously opened in the case 10, and the case 10 can be installed in the interior of the cleaning robot 200, so that the cleaning robot 200 can simultaneously store clean water and collect sewage, and can also greatly save the installation space required in the interior of the cleaning robot 200, thereby facilitating the installation of other components of the cleaning robot 200.
