[0032] A three-way valve electrically connected to the controller is provided on the cabinet 8. The controller controls the three-way valve to open different passages, so that the low-pressure water inlet pipe can transport cleaning agent or clean water to the low-pressure water inlet of the car washing machine, and the car washing machine provides cleaning agent or clean water to the nozzle through the high-pressure water pipe.

[0033] In this specific embodiment, a foam button and a cleaning button are provided on the cabinet 8, and the head and tail ends of the base frame 1 are respectively provided with limit switches electrically connected to the foam button and the cleaning button. When the sliding base 3 touches the limit switch at the tail end, the foam button is reset, and when the sliding base 3 touches the limit switch at the head end, the cleaning button is reset.

[0034] The working process of the automobile chassis cleaning machine corresponding to this embodiment is as follows:

[0035] 1. Install it to the car washing station. When the foam button is pressed, the car washing machine is powered on, the car washing machine starts to work, and the conversion switch inside the three-way valve works. The conversion switch connects the output channel of the foam cleaning agent. At this time, the foam cleaning agent output by the car washing machine is transported to the nozzle through the internal connecting pipe 6. The nozzle sprays the foam cleaning agent. At the same time, the driving motor 7 starts and starts to rotate forward, driving the transmission belt 14 to rotate, thereby driving the entire sliding base 3 to move from the rear of the car to the front of the car. The nozzle sprays the foam cleaning agent to the chassis of the car to realize the process of foaming the chassis. When the sliding base 3 moves to the head end of the base frame 1 and touches the limit switch, the limit switch will trigger the foam button to reset, completing the foaming process.

[0036] 2. When the cleaning button is pressed, the car washer is powered on and starts working. At this time, the conversion switch of the three-way valve is not powered, so the foam channel is closed. At this time, the car washer outputs clean water. At this time, the driving motor 7 reverses to drive the transmission belt 14 to reverse, and the sliding base 3 drives the nozzle to move from the front of the car to the rear of the car. At this time, the nozzle sprays clean water, and the foam cleaning agent is washed during the movement. When the sliding base 3 triggers the limit switch at the rear end of the base frame 1, the cleaning button is reset, so that all working components stop working, and the entire automobile chassis cleaning process is completed.
