The dust-collecting cups (3) comprise a first dust-collecting cup (31) and a second dust-collecting cup (32). The first dust-collecting cup (31) is connected to the first cavity (21), and the second dust-collecting cup (32) is connected to the second cavity (22). The separator comprises a first separator (11) and a second separator (12), the first separator (11) is arranged in the first cavity (21), and the second separator (12) is arranged in the second cavity (22). The first separator (11) comprises an inverted cone filter (111), the shape of the inverted cone filter is an inverted cone, and the surface of the inverted cone filter comprises a filtering surface and a non-filtering surface. The filtering surface (1111) of the inverted cone filter (111) is in communication with the air duct (23). Garbage and sewage mixed together may be introduced into the first dust-collecting cup (31) first. Then, the mixed garbage and sewage may be rotated at a high speed in the first dust-collecting cup (31). Due to the friction with the wall of the first dust-collecting cup (31), the energy of large-particle garbage may be reduced, and finally, the large-particle garbage may slide down along the wall of the first dust-collecting cup (31). Other garbage having small energy loss may be filtered via the filtering surface (1111) of the inverted cone filter (111) and may enter the second dust-collecting cup (32) through the air duct (23).
