The invention discloses a cleaning
base station, cleaning equipment, a cleaning
system and a self-cleaning method, the cleaning
base station is matched with the cleaning equipment capable of being connected with a ground
brush mechanism, and the cleaning
base station comprises a base, a dust collection device and a cleaning device, the cleaning
assembly is arranged in the base and used for spraying fluid into the
butt joint cavity so as to clean and / or dry the floor
brush mechanism; the collecting part comprises a box body in which a collecting cavity is formed; when the cleaning base
station is in
butt joint with the cleaning equipment, a cleaning cavity communicating with the suction port is formed between the ground
brush mechanism and the wall of the
butt joint cavity, and the cleaning cavity, the interior of the cleaning equipment and the collecting cavity communicate to form a closed air path. The fluid is sprayed into the butt
joint cavity through the cleaning
assembly, negative pressure is formed in the collecting cavity, the fluid can be sucked into the cleaning equipment and then enters the collecting cavity, full-link cleaning and
drying of the interior of the floor brush mechanism, the interior of the cleaning equipment and the interior of the cleaning base
station can be achieved, a user does not need to disassemble, assemble and maintain, and the cleaning efficiency is improved. And the self-cleaning effect is effectively improved.
