Description

Technical Field

[0002] As people's living standards continue to improve, the number of private cars is also increasing, and the demand for car washing is also increasing. Self-service car washing machines have developed rapidly due to their convenience, speed and low price.

[0003] The air generated by the air compressors of some existing self-service car washers is stored in an air tank. As the air is compressed, the moisture in the air forms water droplets, and then forms water accumulation in the air tank. If it is not discharged in time, the accumulated water will not only affect the volume of the air tank, but also corrode the air tank, shorten the service life of the air tank, and freeze the inside of the air tank in cold weather. Since the air tank and the air compressor are installed in the cabinet of the car wash machine, it is obviously very troublesome to manually drain the air tank, and it will increase labor costs. Therefore, a self-service car wash machine that can automatically discharge the accumulated water in the air tank is needed. Utility Model Content
