Therefore, the electrolytic water tank of the commonly used hydrogen -rich water machine usually needs to be manually filled with bottled pure water (or deionized water), and the water quality greatly limits the hydrogen -rich water machine.

The UV sterilization lamp 22 can realize sterilization while water production or timed sterilization through the control of the main control board, avoiding the influence of bacteria and other microorganisms in the electrolytic water supply tank 21 on water quality, further ensuring the safety of water quality in the electrolytic water supply tank 21.

[0082] Please refer to Figures 12-13 In another embodiment of the present application, the water tank cover 212 is axially provided with an ultrapure water input interface 2121, an exhaust interface 2123, a UV sterilization lamp mounting port 2124 and an air inlet interface 2125, the ultrapure water input interface 2121 is communicated with the outlet 1222 of the filter core, the inner bottom of the ultrapure water input interface 2121 is provided with a flow limiting hole 2122, the UV sterilization lamp 22 is mounted in the UV sterilization lamp mounting port 2124, the exhaust interface 2123 is connected with the water outlet nozzle 4 of the hydrogen-rich water, and the air inlet interface 2125 is communicated with the electrolytic hydrogen production device 3. Because the oxygen generated by electrolysis of water in the electrolytic tank carries a lot of small water droplets or water vapor, the oxygen output from the oxygen outlet 322 is first guided into the electrolytic water supply tank 21 and then output to the water outlet nozzle or the outside from the exhaust interface 2123 of the water tank, so that the ultrapure water carried by the oxygen can be recovered, water resources can be saved, and the service life of the mixed bed resin filter core 13 can be prolonged.

[0083] Preferably, the outer side wall of the water tank cover 212 is provided with a mounting groove 2126, and a sealing ring 24 is arranged in the mounting groove 2126, and the water tank cover 212 is sealingly connected with the water tank body 211 through the sealing ring 24.

The water level control module 23 is electrically connected to the control device 5. When the high-low water level control module 23 detects that the water level in the electrolytic water supply tank 21 is low, it sends a signal to the main control board, and the main control board controls the electromagnetic valve 11 to open. The mixed bed resin filter element 13 produces ultrapure water and delivers it to the electrolytic water supply tank 21. Conversely, when the high-low water level control module 23 detects that the water level in the electrolytic water supply tank 21 is high, it sends a signal to the main control board, and the main control board controls the electromagnetic valve 11 to close, and the mixed bed resin filter element 13 stops producing ultrapure water. In this way, the water in the electrolytic water supply tank 2 can meet the demand for electrolytic hydrogen production in the electrolytic tank 32, and the water quality is fresh.

[0087] Preferably, the cleaning drain 2113 is installed with a removable soft rubber plug 2116, which blocks the cleaning drain 2113 during cleaning, and is removed after cleaning to drain the water.

In this embodiment, the electrolytic hydrogen production device 3 can be filled with ultrapure water without manual operation. The control device 5 sends a signal to the self-priming pump 31 to control whether the self-priming pump 31 sucks ultrapure water, thereby greatly saving labor cost and improving efficiency.

[0090] After the electrolytic device 32 is installed, the relative position of the hydrogen outlet 323 is higher than that of the oxygen outlet 322 relative to the ground level. Because the density of hydrogen is less than that of oxygen, the position of the hydrogen outlet 323 is arranged to be relatively higher than that of the oxygen outlet 322, which is more conducive to accurately separating and collecting hydrogen and oxygen.
