Description

technical field [0001] The invention relates to a sweeper, in particular to a suction cup for a sweeper. Background technique [0002] An existing cleaning and sweeping vehicle contains a suction cup. The suction cup is composed of a disc body, a dust chamber, a swing-out high-pressure water spray frame, a high-pressure water spray system and rollers. The dust collection chamber, the swing-out high-pressure water spray frame, the high-pressure water spray system and the rollers are all arranged on the disc body. The function of the dust collection room is to pick up the garbage and sewage on the road surface. The high-pressure nozzle assembly is located at the rear of the vacuum chamber, and its function is to flush the cleaned road surface, and the roller is for support and movement. The dust collection chamber is positioned at the middle part of the disk body. The dust collection chamber includes a left dust collection chamber and a right dust collection chamber. The le...

AI Technical Summary

Problems solved by technology

Since the right side of the left vacuum hood is adjacent to the left side of the right vacuum hood, there is a suction dead angle, which makes it difficult to pick up garbage, which affects the garbage collection effect.

During the process of picking up garbage in the above-mentioned dust collection room, because the dust is accumulated on the road surface, it is difficult for the dust to be completely sucked into the dust collection room, thereby affecting the cleaning effect of the sweeper.
