[0030] like Figure 1 and 5As shown, a hydrogen-rich accessory for a direct drinking water delivery pipe includes an accessory main body shell 1, a water inlet 2 is provided at the upper end of one side of the accessory main body shell 1, and a water outlet 1 is provided at the lower end of the other side thereof, a cavity is provided inside the accessory main body shell 1, wherein an aluminum water storage liner 3 is provided inside the cavity, a hydrogen generating mechanism is provided below the aluminum water storage liner 3, wherein the hydrogen generating mechanism is located inside the accessory main body shell 1, a probe 19 for sensing water level and hydrogen molecule content is provided inside the aluminum water storage liner 3, so that the hydrogen-rich accessory has high integration and small size, a water inlet 2 4 is provided at the matching position of the aluminum water storage liner 3 and the water inlet 2, and a water outlet 2 is provided at the matching position of the aluminum water storage liner 3 and the water outlet 1.

[0031] Compared with the traditional hydrogen enrichment device with complex structure and large volume, the hydrogen enrichment accessory of the utility model has high integration, can be installed before the water outlet, and is suitable for ordinary household use.

[0032] like Figure 2 and 3 As shown, the hydrogen generating mechanism includes a hydrogen evolution electrode 6, an oxygen evolution electrode 7, a proton exchange membrane 8 and an electrolytic cell 9, the hydrogen evolution electrode 6 is arranged at the center of the lower surface of the aluminum water storage liner 3, the oxygen evolution electrode 7 is arranged below the hydrogen evolution electrode 6, the proton exchange membrane 8 is arranged between the oxygen evolution electrode 7 and the hydrogen evolution electrode 6, the oxygen evolution electrode 7 is arranged at the center of the upper surface of the electrolytic cell 9, the electrolytic cell 9 and the oxygen evolution electrode 7 are connected by welding, wherein the proton exchange membrane 8 is connected to the hydrogen evolution electrode 6 and the oxygen evolution electrode 7 by welding.

[0033] In this embodiment, the hydrogen evolution electrode 6 is welded to the center of the lower surface of the aluminum water storage liner 3 ; the oxygen evolution electrode 7 is welded to the center of the upper surface of the electrolytic cell 9 .

[0034] like Figure 3 As shown, a group of water holes 20 are provided on the hydrogen evolution electrode 6 ; and water holes 21 matching in size with the water holes 20 are provided on the oxygen evolution electrode 7 .

[0035] In this embodiment, the electrolytic cell 9 is filled with water to provide water for the anode.

[0036] The hydrogen production process is as follows:

[0037] Water is electrolyzed, hydrogen is generated from the hydrogen evolution electrode 6, oxygen is generated from the anode, the proton exchange membrane 8 in the middle can pass water but not oxygen, and hydrogen is directly generated in the aluminum water storage tank 3.

[0038] A power supply assembly 10 is provided below the electrolytic cell 9, and the electrolysis provides power. The power supply assembly 10 is detachably connected to the accessory main body housing 1, and in this embodiment is a snap-on or threaded connection. The power supply assembly 10 can have a built-in battery or an external power supply to ensure the overall energy stability of the accessory.

[0039] like Figure 5 As shown, the water inlet of the hydrogen-rich fitting formed by the water inlet 1 2 and the water inlet 2 4 is provided with a stainless steel water inlet threaded joint 11, and the water outlet of the hydrogen-rich fitting formed by the water outlet 1 and the water outlet 2 is provided with a stainless steel water outlet threaded joint 12, as shown in FIG. Figure 1 As shown, a solenoid valve 13 is provided on the main pipe where the water inlet threaded joint 11 is located, and a one-way valve 14 is provided on the main pipe where the water outlet threaded joint 12 is located.

[0040] The water storage liner of the utility model is made of aluminum, and the aluminum water storage liner 3 is hydrogen-proof, and hydrogen is difficult to escape. In addition, a solenoid valve 13 is provided on the main pipe where the water inlet threaded joint 11 is located, and a one-way valve 14 is provided on the main pipe where the water outlet threaded joint 12 is located, so that a certain pressure exists inside the aluminum water storage liner, which reduces hydrogen escape and increases hydrogen concentration.

[0041] In order to discharge the oxygen generated in the electrolytic cell 9, an exhaust hole 15 is provided on the side of the electrolytic cell 9, and an exhaust hole 2 16 is provided at the matching position between the accessory main body shell 1 and the exhaust hole 15. The exhaust hole 15 and the exhaust hole 2 16 constitute an exhaust hole for discharging oxygen, wherein an exhaust valve 17 is provided at the exhaust hole.

[0042] An electronic display screen 18 is provided on the accessory main body shell 1. The electronic display screen 18 can be used to observe parameter changes on the one hand, and is used to set the required hydrogen molecule content in hydrogen-rich water on the other hand.

[0043] In the present invention, the probe 19 is connected to the control panel via wires, the solenoid valve 13 is also connected to the control panel via wires, the control panel is connected to a power source, a chip is built into the control panel, and the switch start of the solenoid valve is controlled by the chip.

[0044] The specific working process is as follows:

[0045] The water inlet threaded joint 11 and the water outlet threaded joint 12 at the water inlet of the hydrogen-rich accessory are respectively connected to the direct drinking water pipe. When no water is needed, the probe 19 senses the water level in the aluminum water storage tank 3, and then feeds back the signal to the solenoid valve 13. The solenoid valve 13 opens and automatically replenishes water. When the water level reaches a certain height, the solenoid valve 13 closes, and the hydrogen generating mechanism starts to operate. Hydrogen is generated by the hydrogen evolution electrode 6 and dissolved in water to form hydrogen-rich water. Oxygen is generated by the anode and finally discharged through the exhaust valve 17.

[0046] Due to the presence of the proton exchange membrane 8, oxygen cannot pass through the membrane into the water storage tank, which affects the water quality. When the hydrogen molecule content in the water reaches the set concentration, the hydrogen generating mechanism stops running, and when the concentration is lower than the specified content, the probe 19 senses it and the hydrogen generating mechanism starts running again. The electronic display screen 18 can set the required hydrogen molecule content in hydrogen-rich water, and the probe 19 can sense the water level and hydrogen molecule content. When using water, the one-way valve 14 opens, and hydrogen-rich water flows out of the tank. When the water level is too low, the solenoid valve 13 opens to replenish water to prevent water supply interruption. When the one-way valve 14 is opened, the hydrogen generating device does not operate to prevent possible safety hazards. The aluminum water storage tank 3 can store 1.5L of water, which can basically meet the water consumption at one time and ensure stable water quality.
