Road sweepers are equipped with a dust-collecting structure for removing dust.
[0003] According to the dust collection structure of an electric sweeper disclosed in patent number CN 214883301 U, the dust is absorbed by a fan and filtered out by a ventilation filter on the fan bracket. The dust enters the filter element, thereby preventing dust from leaking into the vehicle body and affecting the electrical equipment. However, during the long-term dust filtration process, the ventilation filter of this device is prone to accumulating and adhering a large amount of dust on its surface. The excessive accumulation of dust greatly affects the dust collection effect. In addition, the device is not convenient for disassembling and cleaning the filter element. Therefore, we propose a dust collection structure. Utility Model Content
