Specifically, referring to fig. 1, the water spraying module 220 is disposed in a single stage in the traveling direction of the road surface cleaning device 30, the included angle between the water spraying direction of the water spraying module 220 and the road surface 40 is (30 ± 2 degrees), and the included angle between the plane of the deflector 120 and the road surface 40 is (30 ± 2 degrees). In this embodiment, the angle between the water spraying direction of the water spraying head 224 in the water spraying module 220 and the road surface 40 is preferably 30 degrees, but is controlled to be about 2 degrees above or below 30 degrees, for example, 28 degrees, 28.5 degrees, 29 degrees, 29.5 degrees, 30 degrees, 30.5 degrees, 31 degrees, 31.5 degrees, 32 degrees, and the like, in consideration of installation error factors. Correspondingly, the included angle between the plane of the baffle 120 and the road surface 40 is preferably 30 degrees, but is controlled to be about 2 degrees above or below 30 degrees in consideration of installation error factors, such as 28 degrees, 28.5 degrees, 29 degrees, 29.5 degrees, 30 degrees, 30.5 degrees, 31 degrees, 31.5 degrees, 32 degrees and the like. Within the above range, the water spray module 220 provided at a single stage can greatly reduce the amount of water remaining on the road surface 40.
