It can realize automatic flushing, Spray foam, and then drive multiple roller brushes to rotate and wipe the dirt on the car surface. Due to the direct contact between the roller brush and the car paint, many fine scratches will be left on the car paint. If the number of cleanings is too high, the car surface will gradually lose its luster. Many car wash machine buyers and car wash users are unwilling to use this type of machine, and this type of car wash machine is gradually eliminated by the market.

Referring to Fig. 1, the non-contact car washing machine of the present embodiment includes a track 100, a floor mat 500, a cleaning unit, and a drag chain frame 200, and the track 100 is fixed on the ceiling by a mounting bracket 110, and the cross section of the track 100 is "I" shape, so a track groove 101 is formed on the inner and outer sides of the track (see Figure 6); Parked on the ground mat 500; the cleaning unit is installed on the track 100 and the cleaning unit can walk along the track 100; the drag chain frame 200 is fixedly installed relative to the ground, and can be installed on the ground through a bracket or fixed on the ceiling through a bracket ; The towline frame 200 is provided with a towline, and the towline is used to guide the pipelines and cables that the cleaning unit needs to use. In this way, the cleaning unit is powered, data is transmitted, and the required cleaning liquid (water, detergent, etc.) is input.

1-13, the cleaning unit includes a drive unit 300, a spray arm 400, the spray arm 400 is fixed on the drive unit 300 through a connector 310, and a blower 620 is installed on the drive unit 300, and the blower 620 The air outlet communicates with the spray arm cavity 412 inside the spray arm 410 through the connecting sleeve 621 , and the blower 620 can blow air to the spray arm cavity 412 after starting.

The first pipe 420, the second pipe 430, the third pipe 440, and the fourth pipe 450 are also installed in the inner cavity 412 of the spray arm. The first pipe 420, the second pipe 430, the third pipe 440, the The four pipelines 450 are respectively used to access different car washing fluids to facilitate car washing, and a plurality of nozzles are respectively installed on the first pipeline 420, the second pipeline 430, the third pipeline 440, and the fourth pipeline 450. It is used to accelerate and spray the fluid in the corresponding pipeline to the car being cleaned, so as to achieve the purpose of cleaning the car. In this embodiment, two of the first pipeline 420, the second pipeline 430, the third pipeline 440, and the fourth pipeline 450 are connected to a high-pressure water source, and the other two are respectively connected to a foam fluid and a water wax fluid. The high-pressure water source is provided by After the external equipment pressurizes the water, it enters the corresponding pipeline through the high-pressure water pipe, and the foam fluid and the water wax fluid are respectively pumped into the corresponding pipeline through different pumps. The two pipelines connected to the high-pressure water source can share nozzles or use different nozzles respectively. There are gaps among the first pipeline 420 , the second pipeline 430 , the third pipeline 440 and the fourth pipeline 450 .

The side of the spray arm 410 facing the car washing direction is provided with a through air exhaust port 411 , and the air exhaust port 411 communicates with the inner chamber 412 of the spray arm. During use, the air blower feeds the airflow into the spray arm cavity 412, and the airflow quickly reaches each part of the spray arm cavity 412 along the first pipeline 420, the second pipeline 430, the third pipeline 440, and the fourth pipeline 450, and then After passing through the gaps of the first pipe 420 , the second pipe 430 , the third pipe 440 and the fourth pipe 450 , it is blown out from the air outlet 411 to the automobile. Since the airflow is also a fluid, it can be quickly distributed to various parts of the spray arm cavity 412 under the guidance of the first pipeline 420, the second pipeline 430, the third pipeline 440, and the fourth pipeline 450, while the airflow passes through the first pipeline 420 , the gap between the second pipe 430, the third pipe 440, and the fourth pipe 450 will play the role of air uniformity (similar to the air uniform plate), so that the airflow in the spray arm cavity 412 is evenly distributed from each The air outlet 411 blows out to dry the car.

The traditional air-drying method is to set up 4 blowers on the cleaning unit, which is heavy in structure and unsightly in arrangement, resulting in a weak structure of the entire cleaning unit; the air-drying structure of this embodiment is relatively special, and the blower is arranged in the cleaning unit, and the high-speed airflow Drum into the spray arm, and the spray arm is facing the surface of the car with several air outlets, and the high-speed airflow blows to the surface of the car through the air outlet. This method is proposed for the first time, because the traditional structure does not consider the high-speed airflow and spray The shower pipes share a chamber, that is, the inner chamber of the spray arm, and the traditional structure cannot realize that the two share a chamber at all, because the traditional spray arm needs to move left and right and rotate around the cleaning unit. In this embodiment, the inner cavity of the spray arm is used as the drying air channel at the same time, which greatly simplifies the structure of the equipment. When the airflow enters the inner cavity of the spray arm, it is relatively evenly dispersed by these water pipes. The water pipes act as a splitter plate, and finally the high-speed airflow after the uniform flow is discharged through each exhaust port and blows to the surface of the car.
