Description

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to Chinese Patent Application No. 202010170185.6 filed on Mar. 12, 2020, the content of which is incorporated herein by reference.

FIELD

The present application relates to the field of cleaning robots, and in particular to a robot maintenance station and a robot cleaning system.

BACKGROUND

In the 21st century, artificial intelligence products, including sweeping robots, have attracted more and more attention. The sweeping robots are mainly used to help humans clean indoor ground environments. In general, the sweeping robot will be equipped with a dust box used to accommodate garbage and particulate matter inhaled by the sweeping robot, and the dust box of the current sweeping robot is mainly configured by two manners. The first manner is to install the dust box at a rear portion of the sweeping robot, this kind of dust box is usually removed by rear extraction and occupies little space of the sweeping robot, therefore the garbage that can be accommodated in a single use is relatively small. The second manner is to arrange a groove at a middle portion of the sweeping robot and the dust box is arranged in the middle groove, this kind of dust box can accommodate slightly more garbage than that of the first kind in a single use, however, the dust box arranged at the middle portion of the sweeping robot occupies relatively larger space of the sweeping robot, which results in tighter mounting space for other components. After the dust box of most sweeping robots is filled with garbage, users need to remove the dust box to clean out the garbage in the dust box by themselves, resulting in poor user experience. Therefore, the existing technologies need to be improved.
