Title:
HYPOCHLOROUS ACID DISINFECTION WATER MACHINE
Document Type and Number:
WIPO Patent Application WO/2023/115574
Kind Code:
A1
Abstract:
The present application provides a hypochlorous acid disinfection water machine. The hypochlorous acid disinfection water machine comprises: a water inlet pipeline; a first-stage electrolyte tank, wherein a cation exchange membrane is provided in the first-stage electrolyte tank, and the outlet end of the water inlet pipeline is communicated with the first-stage electrolyte tank; and a second-stage electrolyte tank, wherein the second-stage electrolyte tank is a membrane-free electrolyte tank, a first-stage hypochlorous acid solution in an anode chamber of the first-stage electrolyte tank is communicated with the second-stage electrolyte tank, the first-stage hypochlorous acid solution in the anode chamber of the first-stage electrolyte tank is electrolyzed again in the second-stage electrolyte tank to obtain a second-stage hypochlorous acid solution, and the acidity of the second-stage hypochlorous acid solution is smaller than the acidity of the first-stage hypochlorous acid solution. The hypochlorous acid disinfection water machine provided by the present application can solve the problem in the prior art of poor concentration stability of the hypochlorous acid disinfection water machine.
