[0002] With the rapid development of China's economy, the number of cars is increasing. Cars have become one of the main means of transportation for people to travel and commute. Long-term driving quickly makes cars dirty with dust. Whether in cities or remote areas, the cost of manual car washing is generally high. At the same time, you have to wait in line after rain or snow or in the peak season. Therefore, fully automatic car washing machines have also become popular. During the use of fully automatic car washing machines, it is necessary to keep the water in the water tank sufficient. When the water in the water tank is used up, it cannot be supplied in time, which will seriously affect the normal operation of the self-service car washing machine.

The device achieves the purpose of liquid replenishment by adding a liquid replenishing tank and a liquid sensor. However, the device has the following disadvantages in specific use: 1. A car washing machine generally has two water tanks, one for containing clean water and the other for containing detergent. The device can only achieve the liquid replenishing function of one of the water tanks, which has great limitations; 2. The liquid replenishing tank only plays a supplementary role, and it cannot continuously provide clean water. The water consumption during the car washing process is large.
