Background
The urban road sweeper is widely applied to places such as urban streets, commercial pedestrian streets, parks and the like due to the characteristics of small and flexible volume, rich functions and the like. When the road sweeper works, the left and right sweeping discs firstly sweep the ground garbage on two sides to the middle position, the middle fixed suction pipe provides negative pressure suction force through the fan in the dustbin, and the swept ground garbage is sucked into the dustbin to finish the sweeping work. Corner garbage which cannot be sucked by the fixed suction pipe is sucked by the handheld suction pipe. However, if the handheld suction pipe and the fixed suction pipe work simultaneously to suck garbage, the suction part of the fixed suction pipe can be caused to suck repeatedly all the time, and the suction force of the handheld suction pipe is greatly reduced by separating the suction force of the fan part, so that the working efficiency of the sweeper is low. In the conventional scheme, a spacer is required to be inserted between the handheld suction pipe and the fixed suction pipe so as to change the air duct to realize the switching effect, so that the operation is troublesome, and the handheld suction pipe can only be placed outside the dustbin, thereby affecting the overall attractiveness. The conventional dustbin mostly stretches the suction pipe into the dustbin, so that sucked garbage can be accumulated at the suction pipe, the garbage is unevenly distributed, and the utilization rate of the dustbin body is reduced.
