Abstract: Disclosed are a base station and a cleaning system. The base station is configured for pumping dirt from a cleaning robot and injecting water to the cleaning robot, and the cleaning robot is defined with a host dirt collecting chamber and a host clean water chamber. The base station includes a base station body, a dirt pumping assembly and a water injection assembly. The dirt pumping assembly is arranged in the base station body, and can move relative to the base station body and communicate with the host dirt collecting chamber; The water injection assembly is arranged in the base station body, and can move relative to the base station body and communicate with the host clean water chamber. The technical solution of the present application can make the use function of the base station more diversified, and improve the practicability of the base station.

Abstract: Disclosed are an air duct assembly and a cleaning device. The air duct assembly includes a dirt collecting box, a filter, a cyclone separator and a fan. The dirt collecting box is provided with a dirt collecting cavity and the dirt collecting box is also provided with a dirt inlet and an air outlet communicated with the dirt collecting cavity. The dirt collecting cavity is provided with an air guiding structure, the filter is arranged in the air outlet, the cyclone separator is connected with the air outlet, and the fan is connected with the cyclone separator. The fan drives an air flow to enter into the dirt collecting cavity from the dirt inlet, and enter the cyclone separator from the air outlet after being guided by the air guiding structure, and then enter the fan from the cyclone separator.

Abstract: Disclosed are a base station and a cleaning equipment. The base station includes: a first box defined with a sewage inlet for solid-liquid mixed garbage to enter the first box; a second box communicated with the first box, for receiving liquid garbage from the first box; a cyclone separator communicated with the first box; and a fan communicated with the cyclone separator, the fan is configured to drive an external airflow into the first box from the sewage inlet, and drive the external airflow to enter the fan after passing through the cyclone separator, such that the solid-liquid mixed garbage enters the first box through the sewage inlet.
