Description

[0002] Hydrogen-rich water, also known as hydrogen water, is a mixture with a certain amount of hydrogen mixed in drinking water. Currently, in the production process of hydrogen-rich water, it is necessary to obtain hydrogen by electrolyzing water, and then pressurize the electrolyzed hydrogen and mix it with drinking water so that the water contains a certain amount of hydrogen. When electrolyzing water, in order to avoid generating other substances, such as harmful minerals, etc., it is best to use pure water for electrolysis. However, due to process problems, pure water cannot achieve a completely pure effect, and there will still be a small amount of other ions in the water. Therefore, during the electrolysis process in the electrolytic cell, the ions will move directionally and adsorb on the electrodes. As the electrolytic cell accumulates continuously, a certain amount of ions will be adsorbed on the electrodes. These ions adsorbed on the electrodes will not only affect the working efficiency of the electrolytic cell. And some harmful substances will follow the water cycle and even enter the drinking water mixed with it through the hydrogen outlet, resulting in harmful substances in the hydrogen-rich water.

[0026] In an embodiment of the hydrogen-rich water hydrogen production system of the present utility model, please refer to Figure 1 and Figure 2 ; The hydrogen-rich water hydrogen production system is used to electrolyze pure water to form hydrogen, and the electrolyzed hydrogen is output into drinking water and mixed with drinking water to form hydrogen-rich water. Specifically, the hydrogen-rich water hydrogen production system of this embodiment includes a chassis 100, a water tank 200, a water filtration system 300, an electrolytic cell 400, a two-way pump 500, and a reflux pump 600. A support seat 110 is provided inside the box body 100, the water tank 200 is arranged on the support seat 110, the water filtration system 300 is arranged inside the box body 100 and is connected to the water tank 200. The electrolytic cell 400 is arranged inside the support seat 110, the hydrogen output port 401 of the electrolytic cell 400 is connected to a hydrogen output pipe, the oxygen output port 402 is connected to the reflux pump 600, the reflux pump 600 is connected to the water tank 200, the input port of the electrolytic cell 400 is connected to the first connection port 501 of the two-way pump 500, and the second connection port 502 of the two-way pump 500 is connected to the water tank 200. The two-way pump 500 also has a one-way output port 503, and the one-way output port 503 is connected to a drain pipe (not shown in the drawings).

[0027] For the hydrogen-rich water hydrogen production system of the above embodiment, after the drinking water passes through the water filtration system 300, it enters the water tank 100 to obtain pure water. The two-way pump 500 inputs the pure water in the water tank 100 into the electrolytic cell 400 for electrolysis to form hydrogen and oxygen. The hydrogen, as well as the pure water mixed in the hydrogen, are transported to the hydrogen and drinking water mixing system through the hydrogen output pipe 401, while the oxygen and part of the pure water are returned to the water tank 100 through the reflux pump 600. After the electrolytic cell 400 is used for a period of time, the two-way pump 500 outputs in the reverse direction, then the water in the water tank 200 can enter the electrolytic cell 400 through the reflux pump 600 and the oxygen output pipe 402, and then the two-way pump 500 pumps out the water in the electrolytic cell 400 and outputs it from the one-way output port 503. Thus, the effect of reverse cleaning the inside of the electrolytic cell 400 is achieved, avoiding the accumulation of excessive ions and other substances in the electrolytic cell 400, and effectively avoiding the problem that the accumulated harmful substances enter the drinking water along with the hydrogen.

[0028] Furthermore, refer toFigure 2 and Figure 4 The one-way outlet 503 and the second connection port 502 are located at the same end of the two-way pump 500. This facilitates the connection of the water pipes to the two-way pump 500.

[0029] Furthermore, referring to Figure 2 and Figure 4 the two-way pump 500 includes a pump body 510 and a pump cover 520. The first connection port 501 is provided on the pump body 510, and the one-way outlet 503 and the second connection port 502 are provided on the pump cover 520. Check valves (not shown in the drawings) are provided at the orifices of the one-way outlet 503 and the second connection port 502, and the directions of the two check valves are opposite. In this embodiment, when the two-way pump 500 pumps the water in the water tank 200 into the electrolytic cell 400 for electrolysis, the check valve in the second connection port 502 can be opened, and the check valve in the one-way outlet 503 is closed, so that the water in the water tank 200 can be normally input into the electrolytic cell 400. When cleaning the electrolytic cell 400, when the two-way pump 500 pumps out the water in the electrolytic cell 400, the check valve in the second connection port 502 is closed, while the one-way outlet 503 is opened. Therefore, the cleaned sewage can be discharged from the one-way outlet 503.

[0030] Furthermore, referring to Figure 2 and Figure 3 the hydrogen-rich water hydrogen production system further includes a solenoid valve 700. The solenoid valve 700 has two connectors 701, 702. One of the connectors 701 is connected to the water tank 200, and the other connector is connected to the reflux pump 600. Specifically, when the electrolytic cell 400 stops working, the solenoid valve 700 can close the water tank 200 to prevent the water in the water tank 200 from flowing back. And the water in the electrolytic cell 400 is also completely discharged by the two-way pump 500 to avoid the problem that the residual water in the electrolytic cell 400 causes the water to deteriorate and pollute the electrolytic cell 400.

[0031] Furthermore, referring to Figure 1 and Figure 5 the water filtration system 300 includes a filter 310 and a water pump 320; the filter 310 is connected to the water pump 320, and the water pump 320 is connected to the water tank 200. Therefore, the water purified by the filter 310 is input into the water tank 200 by the water pump 320.

[0032] Furthermore, referring to Figure 1 a steering valve 330 is further provided at the output end of the water pump 320, and the steering valve 330 is connected to the filter 310. In this embodiment, the output direction of the water pump 320 can be changed through the steering valve 330, so that the water flow of the water pump 320 can flow back to the filter 310 to perform reverse flushing on the filter, avoiding the problem of blockage of the filter 310 and improving the filtration efficiency.

[0033] Furthermore, referring to Figure 5, the filter 310 includes a filter cartridge 311 and a filter element 312. The filter element 312 is disposed inside the filter cartridge 311. The outer side of the filter element 312 and the filter cartridge 312 form a water pressure chamber, and the bottom end of the filter element 312 is in sealing cooperation with the inner side wall of the filter cartridge 311. The bottom end of the filter cartridge 311 is provided with a water outlet pipe 313 and a cleaning pipe 314. The water outlet pipe 313 is connected to the water inlet end of the water pump 320, and the cleaning pipe 314 is connected to the steering valve 330. The bottom end of the filter cartridge 311 is further provided with a sewage discharge pipe 315. In this embodiment, when cleaning the filter 310, under the input pressure of the water inlet pipe 316, the water in the water pressure chamber will pass through the filter element 312 and enter the inside of the filter element 312. The water pump 320 will transport the purified water to the cleaning pipe 314, and the cleaning pipe 314 will flush the outer side of the filter element 312. Since the water flow output by the water pump 320 has a relatively large water pressure, it can stir the water flow in the water pressure chamber, and then drive the dirt on the outer side of the filter element 312 to fall off. The flushed sewage can be discharged through the sewage discharge pipe 315. Specifically, the cleaning pipe 314 is communicated with the water pressure chamber.

[0034] Further, referring to Figure 5 , the bottom end of the filter cartridge 310 is further provided with a backwash pipe 317. The backwash pipe 317 is communicated with the inner cavity of the filter element 312 and is connected to the steering valve 330. In this embodiment, after the water filtered by the filter element 312 is pressurized by the water pump 320, it flows back into the inside of the filter element 312. Under the impact of the high-pressure water flow, the water flow will filter in the reverse direction to realize the backwashing of the filter element 312, and further wash down the dirt on the outer side of the filter element 312.

[0035] Further, referring to Figure 2 , a cooling fan 120 is further provided around the support base 110. The cooling fan 120 dissipates heat from the electrolytic cell 400.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
