The water outlet pipe is connected to a transverse water sprinkling pipe. By the above method, the utility model can use a small three-wheel vehicle to replace a large transposition truck to carry out cleaning operations on narrow roads.

[0004] However, the above-mentioned small road electric three-wheel cleaning vehicle still has the following deficiencies:

[0005] In the above device, since the distance between the water spray holes and the cleaning brushes is relatively far, there is a time difference between the cleaning operation and the cleaning operation at the same position. Therefore, dust is extremely easy to overflow during the cleaning process, affecting the current municipal environment. In view of this, we propose a cleaning device for three-wheel high-pressure flushing vehicles. Summary of the Utility Model
