The whole cleaning process saves water resources, and is especially suitable for construction sites where water resources are scarce or cannot be used in large quantities.

[0039] As Figures 1-6As shown, in this embodiment, the connecting device includes a mounting cylinder 11 fixedly sleeved on the side wall of the air nozzle 10, and the spray head 15 is mounted on the mounting cylinder 11. The inner wall of the mounting cylinder 11 is fixedly connected with an annular pipe 14 arranged along the circumference of the mounting cylinder 11, the annular pipe 14 is in communication with the water pipe 9, and the spray head 15 is a plurality of spray heads 15 arranged on the annular pipe 14 along the circumference of the annular pipe 14 and in communication with the annular pipe 14.

[0040] As shown in the Figures 1-6 embodiment, the mounting cylinder 11 is provided with an expansion part 13 at the cylinder opening, and the diameter of the expansion part 13 gradually increases away from the mounting cylinder 11. It should be noted that the expansion part 13 is made of PVC material and has good pressure resistance and corrosion resistance, and its size gradually increases in diameter. This structure not only effectively guides the spraying direction of air flow and water mist, but also increases the diffusion range of water mist to a certain extent, making the cleaning process more efficient and environmentally friendly.

This design allows the elastic retaining ring 17 to provide a certain resistance when the air nozzle 10 is inserted, thereby ensuring that the air nozzle 10 will not easily fall off during use. The elastic retaining ring 17 is usually made of materials with elastic and wear-resistant properties, such as rubber or plastic. The notch 18 design allows the air nozzle 10 to be easily inserted into the elastic retaining ring 17. The retaining ring 17 can fix the air nozzle 10 when it is not in use.

[0044] like Figures 1-6As shown, in this embodiment, the bottom of the bottom plate 1 is provided with a roller 6, and one side of the bottom plate 1 is provided with a push handle 2.

The structure of the roller 6 includes a hub and a spoke, the hub is fixedly connected with the bottom of the bottom plate 1 by bolts, and the spoke connects the hub and the rim to provide support and strength. The rim is wrapped with a wear-resistant rubber layer to increase friction and prevent slipping. The design of the push handle 2 further improves the operation convenience of the device. The push handle 2 is usually made of stainless steel or aluminum alloy material, has the characteristics of light weight and durability, and the surface is treated with anti-slip treatment to provide a comfortable grip. The height and shape of the push handle 2 meet the ergonomic principles, so that the operator can push the device in a natural posture, reducing the fatigue caused by long-time operation.

The combination of the roller 6 and the push handle 2 not only improves the portability of the device, but also enables the device to quickly respond to cleaning needs in the construction site and easily move to the area that needs to be cleaned. This design is particularly suitable for construction environments that require frequent movement of the device, greatly improving the efficiency and flexibility of cleaning work.

[0045] The working principle of the utility model is:

[0046] When it is necessary to clean the wheels of vehicles in the construction site, the staff first unfolds the air pipe 12 from the pipe winding device 4 and connects it with the air pump 3, and at the same time connects the water pipe 9 with the water tank 5. After starting the air pump 3 and the water pump 8, the air pump 3 starts to pressurize the gas, and high-pressure gas is sprayed out through the air nozzle 10 and the air pipe 12, directly acting on the surface of the wheel to strip off the soil and dust. At the same time, the water pump 8 delivers the water in the water tank 5 to the spray head 15, which atomizes the water into fine particles by using the principle of air atomization, forming water mist to effectively suppress the dust generated during cleaning. The staff holds the air nozzle 10 with the spray head 15 and cleans the wheels comprehensively. After cleaning is completed, the air pipe 12 and the water pipe 9 are wound back to the respective pipe winding devices 4, and the air nozzle 10 is inserted into the elastic clasp 17 on the vertical plate 7 for fixation. If the device needs to be moved, the roller 6 and the push handle 2 on the bottom plate 1 can be used to easily push the device to the next working area. The whole process is simple and convenient to operate, water-saving and efficient, and is particularly suitable for construction sites with limited water resources.
