[0002] A spray device is a device used to automatically or semi-automatically spray liquids. During the long driving of a refrigerated truck, some dust will adhere to the surface of the refrigerated truck's shell, and a spray device is needed to spray and clean the dust on the surface of the refrigerated truck's shell.

[0003] There is a refrigerated truck spray test device (authorization announcement number: CN220270686U). After the refrigerated truck enters the spray test room, it automatically performs a rain spray test on the left, right, top and rear sides. The spray heads on the left, right and top sides can be moved by slide rails, ensuring the spray cleaning efficiency of the refrigerated truck by the spray test device.

[0004] However, this type of refrigerated truck spray test device has some shortcomings during actual use: after the outer shell surface of the refrigerated truck is sprayed, some water droplets will remain on the outer shell surface of the refrigerated truck. If the water droplets remaining on the outer shell surface of the refrigerated truck after the spraying treatment are not treated in time, the water droplets will evaporate on the paint surface of the refrigerated truck shell and leave water stains and water marks, affecting the appearance of the refrigerated truck and causing the paint surface of the refrigerated truck shell to lose its gloss. Therefore, we have proposed the utility model to solve the above problems. Utility Model Content
