When the dust collection of the sweeper is completed, the sweeper moves to the integration station, and besides the fact that the sweeper can be charged, the integration station can be communicated with the interior of a dust channel of the sweeper and suck out garbage in the dust channel by using wind pressure. However, the floor sweeping machines of the type described above are simply provided with a dust outlet so that the dust channel in the floor sweeping machine can communicate with the integrated station. But there is no in-depth consideration of how to ensure that the waste in the dust box can be successfully taken out by the integrating station; the reason is that the dust outlet of the sweeper is arranged at the bottom end of the sweeper, and the connecting pipe on the integration station is connected with the dust outlet after being bent, so that the dust outlet path is increased, the wind resistance is correspondingly increased, and the dust collection effect is definitely affected. In addition, most of the bottom surfaces inside the dust boxes are arranged in a horizontal plane, and no design for guiding the dust collection trend in the dust collection process is adopted; therefore, the dust box is not smooth in the process of sucking out the garbage in the dust box by the integration station, or the garbage can be thoroughly discharged from the dust box after repeated operation for many times, so that the dust collection efficiency is low.

Based on the above, in order to solve the above problems, the present utility model provides a sweeper; the dust outlet of the sweeper is arranged on the side wall of the sweeper, so that the connecting pipe on the integration station can be directly communicated with the dust outlet along the horizontal direction, and the connection is very convenient and quick; and the connection path can be reduced; and the bottom wall of the dust channel in the sweeper is obliquely arranged, so that the garbage in the dust channel slides down from the dust inlet to the dust outlet under the action of gravity or wind force, the trend of the garbage in the dust channel can be guided, and the dust discharging effect is further improved.
