It can not only greet guests and serve food in restaurants, but also interact with guests through fixed-term voice in a quiet room. At the same time, the restaurant service robot can also clean restaurants and other places, and the sewage after cleaning will flow into the sewage tank.

[0003] For example, a domestic sewage impurity separation box is disclosed in a Chinese patent (publication number: CN211847391U), comprising a box body, a bottom plate welded inside the box body, a motor connected to the outer wall of the bottom of the bottom plate by bolts, an output shaft arranged at one end of the motor, a threaded head arranged at the top of the output shaft, a sealing ring and a pressure bearing sleeved on the outside of the output shaft, a frame bottom plate arranged at the top of the pressure bearing, a block welded on the frame bottom plate, a nut threadedly connected to the outer wall of the top of the threaded head, a frame body welded at the edge of the outer wall of the top of the frame bottom plate, a screen sleeved on the outside of the frame body, a storage ring welded on one side of the inner wall of the box body, and a primary screening bucket movably arranged on the outer wall of the top of the storage ring. The utility model provides a primary screening bucket, a screen and a motor, the primary screening bucket has a larger screen hole, which can screen out easily separable impurities, reduce the working intensity of the screen and reduce the number of times the impurities inside the screen are cleaned, the screen has a smaller screen hole, and the impurities are cleanly screened out, the motor causes the screen and domestic sewage to rotate synchronously, and the rapid separation of sewage impurities is achieved through centrifugal force.
