Thus, the gravity of the sewage is fully utilized, so that the sewage rapidly enters the sewage cavity 120 from the vacuum cavity 110 under the action of gravity, and the sewage recovery effect of the cleaning robot base station is improved. In combination with the embodiment that the cavity wall of the vacuum cavity 110 is provided with the drainage inclined plane 111, the lower end of the vacuum cavity 110 is integrally in a funnel shape with a wide upper part and a narrow lower part, so that the drainage effect of the cavity wall of the vacuum cavity 110 is improved to a greater extent, sewage can quickly flow into the sewage cavity 120 from the vacuum cavity 110, and the sewage recovery effect of the cleaning robot base station is improved. Further, the sewage chamber 120 is directly below the vacuum chamber 110, so that the gravity of the sewage is utilized to the maximum extent, and the sewage rapidly enters the sewage chamber 120 from the vacuum chamber 110 under the action of the gravity.
The sewage recovery effect of the cleaning robot base station may be improved in other aspects, for example, in some embodiments, the cavity wall of the vacuum cavity 110 is provided with a first connection hole and a second connection hole, the first connection hole is located above the second connection hole, the exhaust pipe of the air exhaust device 200 is communicated with the first connection hole, and the sewage pipe 300 is communicated with the second connection hole. In this embodiment, the first connecting hole for communicating with the exhaust pipe of the air extractor 200 is located above the second connecting hole communicated with the sewage pipe 300, so as to conform to the natural law that sewage flows downwards due to self gravity, and compared with the situation that the first connecting hole is located below the second connecting hole, the air extractor is more beneficial to avoiding the bad situation that sewage plugs the first connecting hole, and ensures that the exhaust pipe of the air extractor 200 can be communicated with the vacuum cavity 110, so as to ensure that the air extractor 200 can quickly and effectively make the vacuum cavity 110 form negative pressure, thereby improving the sewage recovery effect of the cleaning robot base station. In practical application, the first connecting hole and the second connecting hole may be formed on the same side of the wall cavity of the vacuum cavity 110, so that the air extractor 200 and the sewage pipe 300 are mounted on the same outer side of the water tank, so as to improve the compactness of the water tank assembly structure, and facilitate the miniaturization of the cleaning robot base station.
