Abstract: A water tank assembly including a tank body and a one-way valve is provided. The tank body is defined with a clean water cavity communicated with an external pipeline through a water inlet channel, the external pipeline is capable of transporting water to the clean water cavity. The one-way valve is arranged in the water inlet channel and has a first and a second state. During delivering clean water to the clean water cavity, the one-way valve is in the first state to allow water in the external pipeline to be delivered to the clean water cavity, and when clean water is stopped to supply to the clean water cavity, the one-way valve is changed to the second state to restrict the water in the water inlet channel flowing out, such that outflow of the clean water from the water inlet channel is blocked when the external pipeline is removed.

Abstract: A cleaning control method and device including a cleaning robot are provided. The cleaning robot includes a sweeping member and a mopping member which cooperate with each other, and an operating parameter is obtained. A sweeping area formed in real time by the sweeping member, a mopping area formed in real time by the mopping member and a mopped area formed on a lateral side of the cleaning robot are controlled to meet a first preset relationship according to the operating parameter. The first preset relationship includes that a first distance formed between a boundary of the sweeping area closest to the mopped area and a boundary of the mopped area closest to the sweeping area is greater than or equal to a second distance between a boundary of the mopping area closest to the mopped area and a boundary of the mopped area closest to the mopping area.

Abstract: Disclosed are a drainage pump structure and a cleaning base station. The drainage pump structure includes: a drainage cavity with a water inlet, a water outlet and an air port; a one-way valve at the water inlet forming a unidirectional flow path to allow fluid to flow toward the drainage cavity, and another one-way valve at the water outlet forming a unidirectional flow path to allow fluid to flow away from the drainage cavity; and an air source system communicated with the air port and configured to supply air to the air port, suck air from the air port, and adjust an air amount of the air port. The drainage pump structure of this application makes water and impurities during drainage not pass through the air source system, prolongs the service life of the air source system and improve the reliability of the air source system.

Abstract: The present disclosure provides a Mecanum wheel. The Mecanum wheel includes a spoke, a hub, and a plurality of rollers disposed on an outer edge of the spoke. The spoke includes a receiving space to house the hub. The Mecanum wheel further includes a cushioning member, one end of the cushioning member being connected to the spoke, and the other end of the cushioning member being connected to the hub. In response to receiving an impact force, the cushioning member deforms to cause a displacement change of the hub relative to the spoke.

Abstract: A Mecanum wheel includes a first wheel rim and a second wheel rim disposed opposing the first wheel rim. The Mecanum wheel also includes a first hub coupled to the first wheel rim and a second hub coupled to the second wheel rim. The Mecanum wheel further includes a plurality of rollers disposed between the first wheel rim and the second wheel rim. The second hub is depressed in a direction facing the first hub to form a receiving space configured to receive a motor. The first hub and the second hub are both located on a same side of a middle plane having an equal distance to the first wheel rim and the second wheel rim.

Abstract: A four-wheel chassis comprising a body, and a front wheel assembly and a rear wheel assembly detachably coupled to the body. After detached from the body, one of the front wheel assembly and the rear wheel assembly independently moves as a two-wheel chassis. The one of the front wheel assembly and the rear wheel assembly is connected to a wheel driving controller that controls wheels of the two-wheel chassis.
