Abstract (en)
[origin: EP3981311A1] A cleaning device, comprising a water pumping apparatus (30), a cleaning area (10a) and a work execution mechanism (20). The water pumping apparatus (30) comprises a receiving part (31) and a transitional connecting mechanism (33). An accommodating space (310) and a water outlet (30b) that communicates with the accommodating space (310) are formed in the receiving part (31), and the water outlet (30b) communicates with the cleaning area (10a). The transitional connecting mechanism (33) is in drive connection with the work execution mechanism (20), and the transitional connecting mechanism (33) may pump water in the accommodating space (310) into the cleaning area (10a) under the drive of the work execution mechanism (20). The cleaning device uses the ready-made work execution mechanism (20) as a power source, and drives a water pumping operation by means of the transitional connecting mechanism (33) without the need for control by means of a control circuit. The apparatus has high structural reliability and low fabrication costs.
