The water quality monitoring sensor 3 and the tee joint are both fixed on the base by means of sheet metal.

[0029] An electromagnetic valve 4 is fixedly arranged in the housing 1. The electromagnetic valve 4 is connected to the tee joint through a water pipe, and the electromagnetic valve 4 is a normally closed two-way three-way electromagnetic valve. The normally closed type is to isolate the water that has not passed the water quality detection outside the electrolytic cell.

[0030] A sewage discharge pipe and a water delivery pipe are fixedly connected to the electromagnetic valve 4. If the water quality fails the detection by the water quality monitoring sensor 3, it is directly discharged into the sewage pipe network through the sewage discharge pipe. If the water quality is qualified, the electromagnetic valve 4 is opened to supply pure water into the electrolytic cell 5.

[0031] An electrolytic cell 5 is fixedly installed in the housing 1. A DC power supply 10 is fixedly arranged on the housing 1.

The separation tank one 6 automatically drains water into the oxygen-side water tank 8. If the oxygen-side water tank 8 is short of water, the outside pure water immediately replenishes the water tank after the oxygen-side water tank 8 is short of water. The oxygen-side water tank 8 is communicated with the water inlet of the water pump 2 through a water pipe. The pressure controller two 71 is communicated with the hydrogen-side water tank 9 through an air pipe.

[0034] The oxygen generated by the lug connected to the anode in the electrolytic cell 5 enters the first separation tank 6 on the oxygen side. The first separation tank 6 can drain water automatically. When the liquid level in the first separation tank 6 reaches the set value, the drainage of the first separation tank 6 can be started.

A pressure gauge is fixedly installed on the second separation tank 7, and the pressure gauge is used in conjunction with the pressure controller 71. The outlet pressure can be manually set to pressurize the hydrogen, which is convenient for mixing with the pure water in the hydrogen-side water tank 9.

[0038] In this embodiment, the water quality detection sensor 3 uses Holtek RS485 communication, 0 - 3000 ppm;

[0039] The solenoid valve 4 uses SMC's VT307 - 5G1 - 02, a two-way three-way valve;

[0040] The pressure controller includes the pressure controller 61 and the pressure controller 71, which uses Ailaril's AFR2000. The pressure controller is integrated on the corresponding separator.

Then, the pure water in the oxygen-side water tank 8 is supplied to the solenoid valve 4 through the water pump 2. The pure water is detected by the water quality monitoring sensor 3, and the waste water is separated at the solenoid valve 4, while the qualified pure water is supplied into the electrolytic cell 5.
