Description

Water vending machine

technical field

The utility model relates to the technical field of water purification equipment, in particular to an automatic water vending machine.

Background technique

Most of the water bodies in the world are seriously polluted, exacerbating the contradiction of water shortage. Traditional tap water treatment methods can no longer guarantee the provision of high-quality drinking water, and there are still secondary pollution problems in municipal water supply, such as water supply from high-rise water tanks and long tap water pipelines, which will cause potential rust, sediment and Microbial contamination etc. The automatic water vending machine uses RO reverse osmosis membrane. During the filtration process, part of the concentrated water cannot be used and needs to be discharged. The impurities filtered out during the work of the RO membrane need to be washed out to produce concentrated water. The proportion of concentrated water is relatively large, and the water that cannot be used Too much, resulting in a waste of water resources. At the same time, the automatic water vending machine needs to produce a certain amount of concentrated water when it is working in water production. If the concentrated water pipe is blocked due to freezing or other reasons when the automatic water vending machine is working, it will cause damage to the RO membrane, the core component of the automatic water vending machine. Restorative damage will also damage the high-pressure pump inside the water vending machine, which will seriously affect the service life of the water vending machine.
