[0001] The utility model relates to the technical field of ozone water preparation, in particular to a detection device used in the ozone water preparation process. Background Art

It has been increasingly widely used in industries such as disinfection, water treatment, medicine and health, and food preservation. Ozone and water can be mixed to produce ozone water of different concentrations. Ozone water has a wide range of uses. The disinfection effects of ozone water of different concentrations vary greatly. A sterilization rate of 99% requires the preparation of ozone water with a concentration of more than 1.0 mg / L.

[0014] Furthermore, a mixing module is provided in the mixing tank, and the mixing module includes a first air intake pipe and a second air intake pipe.

[0030] Furthermore, the concentration of ozone in the ozone water detected by the ozone concentration detection device can be used to determine whether the quality of the ozone water generated in the ozone water preparation process meets the standards, thereby adjusting the process parameters of the ozone water preparation process.
