The utility model discloses a novel zinc oxide quantitative feeding device which is characterized in that the side face of a supporting column is connected with a discharging channel fixing frame, a discharging channel is arranged in the discharging channel fixing frame, a connecting shaft is arranged on the side face of a rotating base, one end of the connecting shaft is connected with the output end of a second motor, and the other end of the connecting shaft is connected with the output end of the second motor. A gravity sensor is arranged in the rotating base, and a zinc oxide weighing container is arranged at the top of the gravity sensor. According to the zinc oxide weighing device, the zinc oxide weighing container and the gravity sensor are arranged, the gravity sensor weighs zinc oxide raw materials falling into the zinc oxide weighing container, when the weight of the materials needing to be taken is completed, the discharging control assembly is closed, the second motor drives the zinc oxide weighing container to rotate anticlockwise to the position of the discharging channel, and the zinc oxide raw materials are weighed. Weighed zinc oxide is poured into the discharging channel, quantitative taking of the zinc oxide raw materials is achieved in the whole process, and the accuracy of the input amount in the zinc oxide machining process is improved.

The dust box and cleaning robot are disclosed and belong to the technical field of cleaning robots. The dust box comprises a box body, a connecting assembly and a dust bag. The box body is provided with a dust guide hole. The connecting assembly is used for mounting the dust bag in the box body and can connect or close the dust guide hole and the internal space of the dust bag. The connecting assembly comprises a mounting piece and a moving piece. The mounting piece is provided with a mounting hole. The dust bag is mounted in the mounting hole. The inner wall of the box body is provided with a fixing structure. The mounting piece is connected to the fixing structure. The moving piece is slidably arranged between the mounting piece and the fixing structure. The moving piece is provided with a through hole which can connect the dust guide hole and the mounting hole. The moving piece is moved to connect or close the mounting hole and the dust guide hole. The fixing structure comprises a first sliding groove and a first clamping groove. The first sliding groove is arranged below the first clamping groove. The upper end of the moving piece is provided with a first clamping buckle which is clamped with the first clamping groove and a second clamping buckle which is clamped with the top end of the mounting piece. The lower part of the moving piece is inserted into the first sliding groove, so that the moving piece is not easy to be deformed.
