The invention relates to an electric vehicle-mounted water-air mixing cleaning machine, which adopts a water-air mixer to intelligently mix water and compressed air. The water is broken up into tiny water drops in the mixing process, and is rapidly sprayed out along with the compressed air, so that a high-pressure fine water vapor flow is formed. The water-air flow has stronger impact force, can rapidly remove dirt and pollutants on the surface of the automobile, and achieves the effect of high-efficiency cleaning.

Secondly, the invention is provided with the pipe coiling device and the intelligent induction system, so that the cleaning spray gun can flexibly move according to different cleaning scenes. The pipe coiling device can adjust the length of the pipeline, so that the cleaning spray gun can cover a wider area, and the comprehensive cleaning of the surface of the automobile is ensured. The intelligent induction system can automatically recognize the shape and the size of the automobile, the injection angle and the spraying range of the cleaning spray gun can be intelligently adjusted, and the cleaning convenience and the cleaning efficiency are further improved.

In addition, the invention also has multifunctional application. Besides the cleaning function, the cleaning spray gun can realize water spraying, air spraying or water-air mixed spraying through the mode switching of the operation panel. Meanwhile, the cleaning spray gun can also be used for blowing dust removal and tire inflation. The user can freely select different cleaning modes according to actual demands, so that the diversity and the flexibility of the cleaning machine are improved.

In addition, a series of functions such as intelligent remote control, automatic waxing, intelligent identification, autonomous charging, multi-language support and the like are added, so that the user experience and the intelligent level of the cleaning machine are further improved. Meanwhile, the data recording and analyzing function can help merchants to better manage the cleaning machine and the service quality, and optimize service and marketing are realized.

In general, the invention has the advantages of high efficiency, water saving, intelligent operation, multifunctional application, user friendliness and the like, and innovates and advances the automobile cleaning industry. The intelligent control, path planning and automation characteristics of the cleaning device enable the cleaning process to be more convenient and efficient, and different requirements of users on cleaning automobiles are met. Meanwhile, the added functions further improve the intelligent degree and service quality of the cleaning machine, so that the cleaning machine has a larger competitive advantage in the market.
