As shown in
In an embodiment, the flow sensor monitors the flow of the primary hypochlorous acid solution 1050, when the flow of the primary hypochlorous acid solution 1050 increases, it means that excessively liquid inside the water inlet pipeline flows into the primary electrolyte cell 1020, resulting in a decrease of the concentration of the primary hypochlorous acid solution 1050 formed inside the primary electrolyte cell 1020, in such a case, the controller controls the power of the pump 1010 to increase the flow of the electrolyte solution 900, so as to balance the flows of the electrolyte solution 900 and the liquid inlet pipe, so that the primary hypochlorous acid solution 1050 produced inside the primary electrolyte cell 1020 flows to the secondary electrolyte cell 1040 in a stable concentration state.

Of course, it also may be that the controller controls the water inlet pipeline, and the concentration of chlorine ions is adjusted by adjusting the flow of the water inlet pipeline, so that the secondary hypochlorous acid solution 1060 with preset concentration is produced.
Specifically, the pump 1010 outputs different rotation speeds by controlling power of the pump 1010, and the flow of the electrolyte solution 900 is adjusted through different rotation speeds, so as to ensure concentration of primary hypochlorous acid solution 1050 inside the primary electrolyte cell 1020.

In an embodiment, an electromagnetic valve 800 is disposed between the pressure stabilizing part 700 and the primary electrolyte cell 1020, so that on-off of the water inlet pipeline may be controlled by controlling the electromagnetic valve 800, then it may be realized that only when primary electrolysis reaction needs to be carried out in the primary electrolyte cell, the controller sends an electric signal to the electromagnetic valve 800, the electromagnetic valve 800 is in an open state, and liquid in the water inlet pipeline enters the primary electrolyte cell 1020. Of course, the flow of liquid in the water inlet pipeline may also be adjusted by controlling the electromagnetic valve 800, and then concentrations of the primary hypochlorous acid solution 1050 and secondary hypochlorous acid solution 1060 may be controlled.
As shown in

During electrolysis process in the primary electrolyte cell 1020, the anode main reaction:
2Cl−−2e−→Cl2⬆;
Cl2+H2O→HCl+HClO;
2H2O+2e−→H2⬆+2OH−.
During electrolysis, 2Cl− loses electrons to produce chlorine gas, which dissolves in water and reacts with it to produce hydrochloric acid and hypochlorous acid, which exist inside the anode chamber. Due to presence of Na+ and Cl− in NaCl solution, Na+ moves into the cathode chamber and forms NaOH with OH− in the cathode chamber, and NaOH is discharged by a discharge pipeline.
Due to use of a cation membrane electrolytic cell, in the process of electrolysis, only Na+ is allowed to pass the membrane, Cl− and OH− are blocked, so that the problem of mixing of alkali with Cl2 and HClO in the process of electrolysis of a common diaphragm method is solved, therefore, acidic HClO solution may be obtained in the anode chamber of the primary electrolyte cell and NaOH solution may be obtained in the cathode chamber.
