Self-service car washing system

Abstract

The invention relates to a self-service car washing system which belongs to the technical field of car washing. The self-service car washing system comprises a water washing channel and a foam washing channel, wherein the water washing channel comprises a first water inlet pipe, a first electromagnetic valve, a flow meter, a high-pressure water pump and a water gun; the foam washing channel comprises a water supply pipeline and a foam supply pipeline, wherein the foam supply pipeline comprises a foam storage and a micro direct-current diaphragm water pump, and the water supply pipeline comprises a second water inlet pipe and a second electromagnetic valve; the first water inlet pipe and the second water inlet pipe are connected with a water pipe through a tee; foam supplied by the foam supply pipeline and water supplied by the water supply pipeline are collected to a water outlet pipe and then pass through the flow meter and the high-pressure water pump, so as to be sprayed by the water gun. According to the self-service car washing system, under the action of suction of the micro direct-current diaphragm water pump, rich foam forms high-pressure liquid to be fully and uniformly mixed with the water, and the foam washing effect is better.

The self-service car washing machine with the patent number of 201320096429.6 includes a payment activation device, a control device and a spraying device. The payment activation device is a coin acceptor or an IC card reader, which is used to receive user payment operations and output to the control device Start signal, the control device receives the start signal input by the paid start device, and sends a control signal to the spray device according to the start signal, and the spray device executes the control signal to spray liquid, and the above-mentioned patent realizes cleaning Detergent cleaning and water cleaning are switched car washing methods. Detergent cleaning and water cleaning are respectively connected to the pump through pipelines and three-way valves. The pump controls the detergent cleaning liquid or water to self-clean the car through the spray gun. , due to the poor self-priming ability of the water pump alone, coupled with the connection of the pipeline, the detergent cleaning hydraulic pressure in the detergent tank cannot be well injected into the spray gun to perform foam self-cleaning on the car.
