The rapid development in China in recent years enables automobiles to be widely popularized, the domestic automobile washing market becomes larger and larger, however, urban land is very small in size, emerging automobile washing shops cannot go deep into the urban center often, and only the urban land is distributed in a zero-dispersion mode at the periphery of the city, so that much inconvenience is brought to automobile washing of automobile owners.

At present, car washing in car washing shops is divided into three categories, namely pure manual car washing, non-contact car washing and contact car washing. However, each car washing mode has respective disadvantages.

The pure manual car washing usually has the problems of long time consumption, low efficiency and large water resource waste.

The non-contact car washer does not need to be in contact with a vehicle, and the car washer adopts a fan-shaped nozzle to clean the vehicle by using high-pressure water. The non-contact car washing machines in the market all adopt L-shaped jet flow bars, and the jet flow bars can clean not only the side surfaces but also the upper surfaces. However, since the upper transverse part of the L-shaped spray beam is fixed, it is impossible to perform profiling cleaning along with the shape of the top of the vehicle, and in order to clean the model with a relatively high top such as a minibus, the upper nozzle is designed to be 30 cm away from the highest top, which results in that the upper nozzle is far away from the upper surfaces of the head and tail parts of the car, even 1.5 m away, and the sprayed high-pressure water forms water mist when reaching the head and tail, and it is impossible to clean the dirt on the top of the car. The closer the water sprayed by the lateral nozzles is to the vehicle body, the higher the impulsive force is, the cleaner the vehicle is cleaned, but the paint on the surface of the vehicle body can be damaged due to the overlarge water pressure, and the water can permeate into the interior of the vehicle body along gaps on the surface of the vehicle body to corrode parts in the vehicle body.

And when particles are adhered to the surface of the vehicle, the brush can scratch paint on the surface of the vehicle body in the friction process of the brush and the vehicle body.

The utility model discloses an air-dry car washer that contact cleaning and contactless cleaning combined together is disclosed in chinese utility model patent CN201820810690.0, and it discloses, through setting up injection frame and lift brush yoke, can promote the brush yoke, makes the brush yoke not carry out the hydrojet with the automobile body contact and prewash, descend the brush yoke to make the brush and spray the cooperation and clean and the fan and brush the cooperation is wiped futilely to realize contact cleaning and contactless abluent combination.

In the device, because round brush and fan setting are on same crossbeam, the fan is when blowing, because the top brush after accomplishing the washing contains a large amount of moisture, and the moisture on the high-pressure blast can be extruded the round brush, has increaseed the air-dry degree of difficulty. Moreover, in the device, top brush and upright brush are fixed and are wholly gone up and down on the brush carrier, when the top brush cleans the locomotive and the rear of a vehicle top is located the extreme low position, for avoiding founding the brush bottom and not having the accommodation space, consequently founding the brush shorter, lead to when the top brush is located the highest position, found the brush and can't clean whole automobile body side.
