Description

Technical Field

[0001] This utility model relates to the field of hydrogen water machine technology, and in particular to a water circuit system for a commercial hydrogen water machine. Background Technology

[0002] Commercial hydrogen water machines are designed specifically for commercial environments, suitable for public places such as shopping malls, community centers, and beauty salons, to prepare hydrogen-rich drinking water. Their core function is to use advanced technologies such as electrolysis to convert ordinary water into hydrogen-rich water, which is claimed to have health benefits such as antioxidants. The water system of a commercial hydrogen water machine refers to the overall piping and devices inside the equipment used for water flow and treatment. Specifically, it consists of the following key parts: the inlet system, responsible for introducing external water into the hydrogen water machine and performing preliminary filtration to remove large particles and some harmful substances; and the filtration system, which includes multi-stage filtration components, such as pre-filtration and RO reverse osmosis, to ensure that the water quality meets drinking standards. The design and layout of the water system are crucial to ensuring the efficient operation of the hydrogen water machine and water quality safety. Through a carefully designed water system, commercial hydrogen water machines can stably provide users with healthy drinking water rich in hydrogen.

[0003] In commercial applications, traditional hydrogen water machines often only have a single reverse osmosis (RO) membrane or basic filtration system, which is insufficient to meet large-scale water demand. Their filtration components are relatively simple in design, with limited flow capacity, making it impossible to quickly produce large quantities of qualified water. This results in long waiting times and a poor user experience. Pre-filtration typically uses only polypropylene (PP) cotton, which can only remove larger particulate impurities and is ineffective at filtering small molecule harmful substances. The sterilization process may be completely absent or only perform simple sterilization at the outlet, easily leading to secondary pollution. Currently, most hydrogen water machines on the market use outdated electrolysis technology, which has low efficiency and lacks water circulation auxiliary devices, resulting in unstable hydrogen production. Traditional methods of dissolving hydrogen are inefficient, making it difficult to achieve the required hydrogen content in the water. Furthermore, the lack of components to optimize water quality results in low-quality hydrogen-rich water, thus limiting its health benefits.

[0004] Therefore, those skilled in the art have provided a commercial hydrogen water machine water circuit system to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a commercial hydrogen water machine water circuit system. By using dual RO membranes in parallel, this system can significantly improve water treatment throughput, deeply purify water quality, and ensure water purity. At the same time, the system can accurately supply pure water and monitor and protect the electrolyzer in real time. Combined with PEM electrolysis technology and diaphragm pumps, it further improves the efficiency and stability of hydrogen production. In addition, the combination of hydrogen dissolving membrane and membrane-free electrolysis filter enhances the hydrogen dissolving effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A commercial hydrogen water machine water circuit system includes three pre-treatment filter cartridges, each pre-treatment filter cartridge is connected to an inlet solenoid valve, the inlet solenoid valve is connected to a first booster pump, the first booster pump is connected to a first RO membrane and a second RO membrane, the first RO membrane and the second RO membrane are connected to a large water tank, the large water tank is equipped with an immersion UV sterilization lamp and a low-frequency resonance water activator, and the large water tank is connected to an electrolytic cell water tank and a second booster pump;

[0008] The electrolytic cell water tank is equipped with a static UV sterilization lamp. The electrolytic cell water tank is connected to a micro diaphragm pump. The micro diaphragm pump is connected to a first resin filter element. The resin filter element is connected to a TDS probe. The TDS probe is connected to a PEM electrolytic cell. The PEM electrolytic cell is connected to a second flow meter. The second flow meter is connected to a second resin filter element. The second resin filter element is connected to the electrolytic cell water tank.

[0009] The second booster pump is connected to three mineralization filter elements, the three mineralization filter elements are connected to a first flow meter, the first flow meter is connected to a first high-pressure switch, the first high-pressure switch is connected to a first flow-through UV germicidal lamp, the first flow-through UV germicidal lamp is connected to a hydrogen dissolving membrane, the hydrogen dissolving membrane is connected to a membraneless electrolytic hydrogen production filter element, the membraneless electrolytic hydrogen production filter element is connected to a second flow-through UV germicidal lamp, and the second flow-through UV germicidal lamp is connected to an outlet solenoid valve.

[0010] The PEM electrolyzer is connected to a check valve, which is connected to a second high-pressure switch, which is connected to the hydrogen dissolving membrane.

[0011] Furthermore, the electrolytic cell water tank is connected to a second ball valve, the first RO membrane and the second RO membrane are connected to a wastewater solenoid valve, the large water tank is connected to a first ball valve, and the first ball valve, the second ball valve and the wastewater solenoid valve are connected to a wastewater outlet.

[0012] Furthermore, the three pretreatment filter elements are each composed of PP+CTO+CTO.

[0013] Furthermore, the large water tank has a volume of 30L, and the electrolytic cell water tank has a volume of 1L.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model proposes a commercial hydrogen water machine water circuit system. This system employs two reverse osmosis (RO) membranes in parallel configuration to form a standard reverse osmosis water production system, significantly improving the system's water production efficiency to meet the higher water demands of commercial environments. The system's pretreatment filter cartridge uses a combination of polypropylene (PP) and activated carbon (CTO) filter cartridges to achieve comprehensive preliminary filtration of the raw water. Furthermore, the system incorporates multiple sterilization processes, including immersion ultraviolet (UV) germicidal lamps, static UV germicidal lamps in the electrolysis tank, and first and second flow-through UV germicidal lamps, ensuring comprehensive and deep sterilization of the water in the water circuit system, effectively preventing bacterial growth and spread to subsequent treatment stages. Compared to existing technologies, this system achieves a more thorough sterilization effect, thereby ensuring high water purity. The ion exchange resin filter cartridge in the system further purifies the pure water in the large water tank, ensuring that the TDS value of the pure water entering the proton exchange membrane (PEM) electrolysis cell is below 5 PPM. Meanwhile, the TDS probe monitors the TDS value of the pure water entering the PEM electrolyzer in real time. Once the TDS value exceeds the set threshold, the system will automatically suspend the electrolysis operation and issue an alarm signal until maintenance personnel troubleshoot the problem. This mechanism effectively protects the PEM electrolyzer, extends its service life, and improves the purity of the hydrogen produced by electrolysis.

[0016] 2. This utility model proposes a commercial hydrogen water machine water circuit system. This system adopts proton exchange membrane (PEM) electrolysis water production technology, using the proton exchange membrane as a solid electrolyte and pure water as raw material for hydrogen production, thereby improving hydrogen production efficiency and hydrogen purity. Simultaneously, a micro diaphragm pump ensures the circulation of pure water in the electrolysis water circuit, providing sufficient water for the electrolyzer and effectively removing the heat generated during electrolysis, thus improving the working efficiency and stability of the electrolyzer and ensuring stable hydrogen production. Furthermore, the polytetrafluoroethylene (PTFE) permeable membrane (hydrogen-dissolving membrane) used in the system, by applying a hydrogen pressure of 0.28-0.4 MPa around the membrane and allowing water to flow through the membrane, efficiently dissolves hydrogen in the water, producing hydrogen-rich water with high hydrogen content. The membrane-free electrolysis hydrogen production filter further increases the hydrogen content and creates a negative potential in the effluent, generating small molecule clusters of water, resulting in better hydrogen dissolution compared to existing technologies. The second flow meter can monitor the water circulation status in real time. Once a blockage is detected that prevents the flow meter from detecting the pulse signal, the system will automatically stop the electrolysis operation and issue an alarm. After maintenance personnel troubleshoot the problem, it effectively prevents problems such as dry burning and damage to the electrolytic cell caused by water blockage. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figure 1 The present invention provides an embodiment of a commercial hydrogen water machine water circuit system, comprising three pre-treatment filter elements 1, each composed of PP+CTO+CTO, and connected to an inlet solenoid valve 2. The inlet solenoid valve 2 is connected to a first booster pump 3, which is connected to a first RO membrane 4 and a second RO membrane 5. The first RO membrane 4 and the second RO membrane 5 are connected to a large water tank 8, which is equipped with an immersion UV sterilization lamp 6 and a low-frequency resonance water activator 7. The large water tank 8 is connected to an electrolytic cell water tank 17 and a second booster pump 11. The large water tank 8 has a volume of 30L, and the electrolytic cell water tank 17 has a volume of 1L.

[0022] Specifically, the pre-treatment filter cartridge 1 uses a combination of PP+CTO+CTO, which can comprehensively and specifically filter impurities in the water. The PP material can intercept large particles such as silt, while CTO can effectively adsorb residual chlorine, organic matter, etc., laying a good foundation for subsequent fine treatment. The two RO membranes are connected in parallel, which greatly improves the water production flow compared to a single RO membrane, and can quickly meet the frequent and large water demand in commercial environments, shortening the user's waiting time.

[0023] The electrolytic cell water tank 17 is equipped with a static UV sterilization lamp 16. The electrolytic cell water tank 17 is connected to a micro diaphragm pump 18. The micro diaphragm pump 18 is connected to a first resin filter element 19. The resin filter element is connected to a TDS probe 20. The TDS probe 20 is connected to a PEM electrolytic cell 21. The PEM electrolytic cell 21 is connected to a second flow meter 22. The second flow meter 22 is connected to a second resin filter element 23. The second resin filter element 23 is connected to the electrolytic cell water tank 17.

[0024] Specifically, the static UV sterilization lamp sterilizes the PEM electrolyzer again in the water tank 17, providing double sterility protection and reducing the interference of impurities on the electrolysis process. The micro diaphragm pump 18 circulates pure water, continuously supplying water to the electrolyzer to ensure continuous electrolysis, and also removing the heat generated by electrolysis to stabilize the working temperature of the electrolyzer and improve electrolysis efficiency and stability. The first resin filter 19, in conjunction with the TDS probe, strictly controls the TDS value of the pure water entering the PEM electrolyzer to below 5 PPM, avoiding corrosion of the electrolyzer by high TDS water, affecting hydrogen purity, and extending the service life of the electrolyzer. The second resin filter 23 further purifies the circulating water to maintain high water quality standards.

[0025] The second booster pump 11 is connected to three mineralization filter elements 12. The three mineralization filter elements 12 are connected to a first flow meter 13. The first flow meter 13 is connected to a first high-pressure switch 14. The first high-pressure switch 14 is connected to a first flow-through UV germicidal lamp 15. The first flow-through UV germicidal lamp 15 is connected to a hydrogen dissolving membrane 26. The hydrogen dissolving membrane 26 is connected to a membraneless electrolytic hydrogen production filter element 27. The membraneless electrolytic hydrogen production filter element 27 is connected to a second flow-through UV germicidal lamp 28. The second flow-through UV germicidal lamp 28 is connected to an outlet solenoid valve 29.

[0026] Specifically, three mineralization filter cartridges 12 mineralize the water, replenishing beneficial minerals and enhancing its nutritional value; the first flow meter 13 accurately measures the filling volume, facilitating control of water costs and product energy consumption; the first high-pressure switch 14 monitors water pressure in real time, promptly cutting off the circuit when the pressure is too high to prevent dangerous situations such as pipe bursts and ensure safe equipment operation; the first flow-through UV sterilizer provides final sterilization before hydrogen dissolution, preventing bacterial contamination of the hydrogen dissolution process; the hydrogen dissolution membrane 26 utilizes a clever pressure difference principle to efficiently dissolve hydrogen, producing high-hydrogen-value hydrogen-rich water; the membrane-free electrolysis hydrogen production filter cartridge 27 further optimizes the quality of hydrogen-rich water, increasing the hydrogen value, forming negative potential and small molecule clusters, and enhancing health benefits; the second flow-through UV sterilizer sterilizes at the water outlet, ensuring that every drop of water used by the user is safe and sterile.

[0027] PEM electrolysis cell 21 is connected to a check valve 24, the check valve 24 is connected to a second high-pressure switch 25, and the second high-pressure switch 25 is connected to a hydrogen dissolving membrane 26.

[0028] Specifically, the check valve 24 effectively blocks the reverse impact of the filling water pressure on the PEM electrolyzer, protecting the internal precision structure of the electrolyzer from damage; the second high-pressure switch 25 precisely controls the working pressure range of the electrolyzer. When the filling water pressure is too high and reaches 0.4MPa, the electrolyzer operation is suspended, and it is restarted after the pressure drops back to 0.28MPa, ensuring stable hydrogen outlet pressure and avoiding safety hazards such as hydrogen leakage and electrolyzer malfunction caused by abnormal pressure, thus ensuring stable and safe operation of the equipment.

[0029] The electrolytic cell water tank 17 is connected to a second ball valve, the first RO membrane 4 and the second RO membrane 5 are connected to a wastewater solenoid valve 9, the large water tank 8 is connected to a first ball valve 10, and the first ball valve 10, the second ball valve and the wastewater solenoid valve 9 are connected to a wastewater outlet.

[0030] Specifically, the wastewater solenoid valve 9 facilitates the timely discharge of wastewater generated by the RO membrane filtration, keeping the system clean and preventing residual wastewater from breeding bacteria and affecting water quality; the first ball valve 10 and the second ball valve provide convenient drainage channels for the large water tank 8 and the electrolysis tank 17, respectively, which facilitates the quick emptying of the water tanks during equipment maintenance and cleaning, improves maintenance efficiency, and extends the service life of the equipment.

[0031] Working Principle: Tap water first enters the pre-filter composed of PP+CTO+CTO, removing large particles, residual chlorine, organic matter, and other impurities, thus initially purifying the water. Next, the water passes through the inlet solenoid valve 2, is pressurized by the first booster pump 3, and flows into the first and second RO membranes for reverse osmosis filtration, removing dissolved solids, heavy metals, bacteria, etc., to obtain pure water. Filtered wastewater is discharged through the wastewater solenoid valve 9, and the pure water is stored in a 30L large water tank 8. Inside the tank, an immersion UV sterilizer disinfects and prevents bacteria growth, while a low-frequency resonance water activator 7 causes water molecules to resonate, increasing their energy and activity, making the water more permeable and further optimizing water quality. Under the action of the second booster pump 11, some of the water in the large water tank 8 flows into the 1L electrolysis tank 17, where a static UV sterilizer performs secondary sterilization to ensure sterility. A micro diaphragm pump 18 circulates the pure water in the electrolysis circuit, providing stable water supply and heat dissipation to the PEM electrolysis cell, improving electrolysis efficiency and stability. Before entering the PEM electrolyzer, water is purified by the first resin filter element 19 and monitored by a TDS probe to ensure the TDS value is below 5 PPM. If the TDS value exceeds the threshold, electrolysis is suspended and an alarm is triggered. In the PEM electrolyzer, hydrogen is produced by electrolysis using a proton exchange membrane as the electrolyte and pure water as the raw material. The check valve 24 isolates the influence of the filling water pressure on the electrolyzer. The second high-pressure switch 25 stops the electrolyzer when the filling water pressure reaches 0.4 MPa and restarts it when the pressure drops to 0.28 MPa to ensure stable hydrogen outlet pressure. The hydrogen produced by the PEM electrolyzer is mixed with water treated by the first flow meter 13, the first high-pressure switch 14, and the first flow-through UV sterilizer via the check valve 24 and the second high-pressure switch 25 in the hydrogen dissolving membrane 26. The hydrogen dissolving membrane 26 dissolves hydrogen using the hydrogen pressure difference of 0.28-0.4 MPa to produce hydrogen-rich water with a high hydrogen value. The hydrogen-rich water then passes through a membraneless electrolysis hydrogen production filter 27 to increase its hydrogen value, forming negative potential and small molecular clusters of water. Finally, it is sterilized by a second flow-through UV germicidal lamp and flows out through an outlet solenoid valve 29 for user use.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
