In order to accelerate the evaporation of water on the ground surface sprayed by the water spray device 20, the sweeping apparatus further includes: the blowing device 30 is used for blowing air to the ground cleaned by the water spraying device 20, the blowing device 30 is disposed on the main body structure 10 or the suction nozzle device 40, and specifically, the blowing device 30 may be directly connected to the main body structure 10 or indirectly connected to the main body structure 10 through the suction nozzle device. Since the blowing device 30 is used for blowing air to the ground cleaned by the water spraying device 20, any installation position of the blowing device 30 that can achieve the purpose is an implementable technical solution, and the main body structure 10 mainly plays a role in bearing the blowing device 30.

Further, the blowing device 30 is configured to blow cold air or hot air to the ground cleaned by the water spraying device 20. When the weather is cold, the hot air can be turned on to accelerate the ground drying, and when the weather is warm, the cold air can be turned on to save energy. Here, the cold wind means wind that is not heated. It can be understood that, in the implementation process, the wind speed of the blowing device 30 can be adjusted reasonably according to the actual weather conditions.

According to fig. 1, one side of each of the water spray devices 20 is provided with the blowing devices 30, and the blowing direction of each of the blowing devices 30 is directed toward the working area of the suction nozzle device 40. Therefore, the blowing device 30 has another function of blowing the portion of the garbage on the floor surface which is not swept to the working area of the suction nozzle device 40 by the blowing device 30. Therefore, the added blowing device 30 can also play a role in improving the cleaning quality.

Alternatively, the number of the blowing devices 30 is two, and the two blowing devices are respectively located at both sides of the front or the rear of the suction nozzle device 40. In fig. 1 and 2, the blowing devices 30 are located at both sides of the front of the nozzle device 40, and in fig. 5, the blowing devices 30 are located at both sides of the rear of the nozzle device 40. Here, "front" and "rear" are defined by the traveling direction of the road surface cleaning device, and the traveling direction of the road surface cleaning device is the front and the reverse direction is the rear.
