In daily life, the ozone water is usually prepared by tap water and ozone gas through a gas-water mixer, a tap water supply pipeline and an ozone gas supply pipeline are connected to the gas-water mixer together, and an outlet of the gas-water mixer is an ozone water outlet. However, the existing ozone generating device cannot adjust the ozone concentration of the ozone water according to actual demands, or needs to be manually controlled to adjust the ozone concentration of the ozone water, a mechanical manual switch on the market is inconvenient to operate, low in adjustment precision and low in practicality, and some negative pressure switches are not durable and are easy to corrode by ozone.
