[0003] 1, hot air blower: responsible for generating high-temperature hot air, the heating element (such as electric heating wire) in it can rapidly increase air temperature, provides heat source for melting ice and snow, drying wet road surface.

[0004] 2, blower: used to blow normal temperature air, can work alone when cleaning dust and light sundries, relies on wind power to blow away road surface pollutants.

[0005] 3, generator: provides power support for hot air blower and blower, ensures that equipment can continuously and stably run when working outdoors.

[0006] 4, air pipe: as transmission channel connecting hot air blower, blower and road surface, plays the key role of conveying hot air and normal temperature air, and its structure design directly affects the concentration degree of wind power, wind direction control and cleaning effect.

[0007] At present, to meet the road cleaning demand, manufacturers have developed various road surface hot -blast sweeping equipment and related design.Some manufacturers adopt split design, i.e.hot air blower, blower, generator and other components are transported separately, and then assembled in construction site.Other manufacturers fix equipment on large special vehicle, and vehicle is equipped with power source, and equipment structure is relatively fixed.In addition, some manufacturers consider the flexibility of air pipe, and adopt simple telescopic air pipe design, but there are still many deficiencies in actual operation.

[0008] However, the above-mentioned implementation still has a series of problems. In terms of device transportation and storage, the split design needs to consume a lot of time and manpower for disassembly, transportation and assembly of parts, which is not only low in efficiency, but also easy to cause damage to parts during disassembly and assembly. The device fixedly installed on a large vehicle has high requirements for storage space due to its large size, and has poor transportation flexibility, which cannot meet the cleaning needs of small construction sites or narrow roads. For the air pipe design, due to the inability to effectively fold, a large space is occupied during transportation or storage, and the height from the ground cannot be effectively adjusted, which has poor practicability. In view of these problems, the present application provides an innovative solution, and designs a road surface hot air blowing device with integrated and foldable and telescopic air pipes. The device is convenient to transport, the foldable and telescopic design of the air pipe can save space during transportation and storage, and can flexibly adjust the length during cleaning operation to adapt to various complex construction scenes, thereby greatly improving the practicability and working efficiency of the device.
