WIPO Patent Application WO/2022/083066
Kind Code:
A1
Abstract:
A cleaning robot, comprising: a moving mechanism, a sweeping mechanism, a mopping mechanism and a main controller. The mopping mechanism comprises a water tank (21), a water outlet pipeline (22), a roller brush (24) and a water circulation system; the water tank (21) supplies water to the roller brush (24) by means of the water outlet pipeline (22); the water circulation system comprises a squeeze roller (31), a water receiving tray (32) for accommodating sewage, a filter mechanism and a water pump (34); and the squeeze roller (31) can squeeze out the sewage in the roller brush (24), the squeezed sewage flows into the water receiving tray (32), the sewage in the water receiving tray (32) is filtered by the filter mechanism to obtain secondary clean water, and the secondary clean water is pumped back into the water tank (21) by the water pump (34) and continues to participate in the circulation. Because the sewage produced by mopping is reused, the water in the water tank (21) is consumed slowly, and even if the water tank (21) is designed to be small in volume, the requirement of mopping for a long time can stilled be satisfied. Meanwhile, because water does not need to be manually and frequently added, cleaning efficiency is improved and labor cost is saved.
