Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0029] Example:

[0030] A hydrogen production device, such as Figure 1 As shown, it includes a water tank 8, an electrolytic cell 13, a water inlet system, and a circulating water system; the water inlet system is connected to the water tank 8, and the circulating water system is connected to both the water tank 8 and the electrolytic cell 13. The water tank 8 is equipped with an inlet, an outlet, and a return outlet; as shown...Figure 2 As shown, the water inlet system comprises a water inlet pipeline 1, a first water pump 5 and a permeation device 6. The two ends of the water inlet pipeline 1 are connected with a tap water interface and a water inlet of a water tank 8 respectively. The first water pump 5 and the permeation device 6 are arranged on the water inlet pipeline 1, and the permeation device 6 is located near the water tank 8. Figure 3 As shown, the circulating water system comprises a circulating water pipeline 14, a second water pump 10, a resin tank 11 and a cooling fan 15. The two ends of the circulating water pipeline 14 are connected with a water outlet and a backwater outlet of the water tank 8 respectively. The middle part of the circulating water pipeline 14 is connected with an electrolytic cell 13. The second water pump 10, the resin tank 11 and the cooling fan 15 are arranged on the circulating water pipeline 14 in sequence. The resin tank 11 and the cooling fan 15 are arranged on the two sides of the electrolytic cell 13 respectively, and the cooling fan 15 is located near the backwater outlet of the water tank 8.

[0031] The first water pump 5 is used to pump tap water into the pipeline, and the first water pump 5 pressurizes the tap water. The pressurized water passes through the permeation device 6 to achieve the purpose of water production and is finally stored in the water tank 8. The second water pump 10 is used to pump the water in the water tank 8 into the circulating water pipe 14, and the circulating water pipe 14 is used to send the water into the electrolytic cell 13 and send the water in the electrolytic cell 13 back to the water tank 8. The resin tank 11 is used to soften the calcium ions in the water. The cooling fan 15 is used to cool the water passing through the electrolytic cell 13. When the water is ionized, it absorbs part of the potential energy and then releases part of the potential energy. Therefore, the remaining water has a temperature, and a high temperature has a certain influence on the production of hydrogen in the electrolytic cell 13. Therefore, a cooling fan 15 is added to cool the water, which can improve the hydrogen production. Specifically, in use, the first water pump 5 pumps tap water into the water inlet pipeline 1 and pressurizes the water. The pressurized tap water is treated by the permeation device 6 to remove impurities and pollutants, so as to ensure that the water quality meets the requirements of electrolysis, and finally the treated water is introduced into the water tank 8. The water tank 8 stores the treated water and provides water supply required by the whole system. The second water pump 10 pumps the water in the water tank 8 into the circulating water pipe 14, and the pumped water will be sent into the electrolytic cell 13 for electrolysis reaction. The resin tank 11 is arranged in the circulating water pipe 14 and is mainly used for softening the water and removing calcium ions in the water to prevent scaling in the electrolytic cell 13 and ensure the electrolysis efficiency. The water is electrolyzed in the electrolytic cell 13 and is decomposed into hydrogen and oxygen. Heat is released during the reaction process, causing the water temperature to rise. In the circulating water pipe 14, the cooling fan 15 is used to reduce the temperature of the water passing through the electrolytic cell 13 to avoid the adverse effects of high temperature on the electrolysis process. The reduction of water temperature can improve the electrolysis efficiency and thus increase the hydrogen production. The water in the electrolytic cell 13 circulates into the backwater inlet and then flows back to the water tank 8, realizing effective management and cyclic use of water resources. In the utility model, the permeation device 6 effectively removes impurities in the water, ensures the purity of the water in the electrolysis process, and improves the yield and quality of hydrogen. The cooling fan 15 reduces the temperature of the water coming out of the electrolytic cell 13, that is, reduces the temperature of the circulating water, realizes control of the reaction temperature, effectively improves the electrolysis efficiency, and enhances the hydrogen production.

[0032] In a preferred embodiment, the water inlet pipe 1 is provided with a stop valve 2, a pressure sensor 3, and an electric valve 4; the stop valve 2, the pressure sensor 3, and the electric valve 4 are sequentially arranged on the side close to the tap water interface, wherein the stop valve 2 is connected with the pressure sensor 3, and the electric valve 4 is located on the side close to the first water pump 5, and the first water pump 5 uses a high-pressure pump. The stop valve 2 is used to control the opening and closing of the water flow, which can effectively control the supply of tap water. Through manual or automatic mode, the water flow can be managed in time to avoid unnecessary water loss or system failure. The pressure sensor 3 is used to monitor the pressure condition in the water pipe in real time to ensure that the water pressure is within the safe and working range. The electric valve 4 is a valve that can be automatically controlled, and the opening and closing of the water flow are realized through electric drive to meet the dynamic requirements of the system on the flow or pressure. The first water pump 5 selects a high-pressure pump to provide sufficient water pressure for the water inlet pipe 1 to enable the water flow to enter the permeation device 6 and the water tank 8 efficiently.

[0033] In a preferred embodiment, the water tank 8 is provided with a liquid level sensor 7. The liquid level sensor 7 can accurately sense the actual water level in the water tank 8 to realize the water level monitoring of the water tank 8.

[0034] In a preferred embodiment, the electrolytic cell 13 is provided with a gas delivery pipe and a water delivery pipe. The main function of the gas delivery pipe is to guide the hydrogen generated inside the electrolytic cell 13 for use. In actual use, hydrogen can be inhaled through the nostrils alone or mixed with water and drunk into the stomach. The water delivery pipe is used to deliver the water in the electrolytic cell 13 to the circulating water pipe 14.

[0035] In a preferred embodiment, the water tank 8 is provided with an electric conductivity instrument 9. The electric conductivity instrument 9 is used to detect the electric conductivity of the water in the water tank 8. When the electric conductivity of the water in the water tank 8 is detected to be out of standard, the water in the water tank 8 and the pipeline needs to be discharged in time and flushed clean to ensure that the hydrogen production amount is not affected.

[0036] In a preferred embodiment, the circulating water pipe 14 is provided with a one-way valve 12 between the resin tank 11 and the electrolytic cell 13. The main function of the one-way valve 12 is to ensure that the water flow can only flow towards the electrolytic cell 13 to prevent the water flow from flowing back to the resin tank 11, thereby maintaining the efficiency of water circulation and the stability of the system.

[0037] In a preferred embodiment, the second water pump 10 uses a diaphragm pump. The reason for choosing this type of pump is that it can ensure efficient water flow delivery while providing excellent fluid sealing and reliability. The diaphragm pump realizes the suction and discharge of liquid through the reciprocating movement of a flexible diaphragm. The movement of the diaphragm causes the volume to change, forming negative pressure to suck in the liquid, and then the liquid is pushed to the discharge end through the further movement of the diaphragm. This mechanical structure enables the diaphragm pump to effectively isolate the liquid from the driving components

[0038] In a preferred embodiment, the water tank 8 is made of stainless steel material. The chemical stability of stainless steel can prevent harmful substances in water from reacting with the material of the water tank 8, thereby maintaining the purity and safety of the stored water.

[0039] In a preferred embodiment, the permeation device 6 adopts a reverse osmosis membrane. This choice is based on the fact that reverse osmosis membranes can efficiently remove dissolved salts, organic matter, bacteria and other impurities in water, thereby significantly improving the purity of water. Reverse osmosis membranes can make water molecules pass through the membrane by applying pressure, while larger or charged pollutants such as salt ions and other impurities are blocked on the other side of the membrane. This process is achieved through the mechanism of selective permeation, ensuring that only pure water can pass through the membrane surface, thereby significantly improving the purification effect of water.

[0040] In a preferred embodiment, the water tank 8 is provided with an electric control box 16, which is connected to the first water pump 5, the second water pump 10, the electrolytic tank 13 and the cooling fan 15. Through this design, centralized control and automatic management of these devices can be achieved, thereby improving the operating efficiency and safety of the system. For example, after the electric control box 16 is connected with the water pump, the start and stop of the first water pump 5 can be intelligently adjusted according to the signal feedback of the liquid level sensor 7, ensuring that the water level remains within the set range, avoiding the situation of dry burning and low water level of the water pump, thereby optimizing the use of water resources. The electric control box 16 adjusts the current and voltage in the electrolysis process by controlling the power supply of the electrolytic tank 13, to ensure the efficiency of the electrolysis reaction and the quality of the product, to meet the needs of water treatment. During the electrolysis process, the cooling fan 15 provides a cooling function to prevent overheating. The electric control box 16 can automatically start the cooling fan 15 when the temperature of the electrolytic tank 13 rises to a set threshold, ensuring that the equipment operates at an appropriate temperature and prolongs the service life of the equipment.

[0041] In a preferred embodiment, the electrolytic cell 13 comprises a storage cylinder 23, end plates 19, a pair of threaded rods 21, electrode plates 20 and insulating sealing cylinders 22; the end plates 19 are threadedly connected to the two ends of the pair of threaded rods 21, and the threads on the two sides of the pair of threaded rods 21 are in opposite directions. The electrode plates 20 and the insulating sealing cylinders 22 are arranged between the end plates 19, the electrode plates 20 are provided with flow-through holes 30 in the middle, and the electrode plates 20 and the end plates 19 are arranged alternately, and the insulating sealing cylinders 22 are arranged close to the end plates 19. The electrode plates 20 comprise cathode plates 24 and anode plates 29, and the cathode plates 24 and the anode plates 29 are arranged alternately in the electrode plates 20. The cathode plates 24 are provided with first connecting pieces 25 on one side of the top, all the cathode plates 24 are connected together through the first connecting pieces 25, and a negative electrode connector 26 is connected to one side of the first connecting pieces 25. The anode plates 29 are provided with second connecting pieces 28 on one side of the top, all the anode plates 29 are connected together through the second connecting pieces 28, and a positive electrode connector 27 is connected to one side of the second connecting pieces 28. The storage cylinder 23 is connected to the circulating water pipe 14, the end plates 19 are provided with water inlet holes close to the bottom, and are provided with air inlet holes close to the top, one end of the water delivery pipe 18 is connected to the water inlet holes, and the other end is connected to the storage cylinder 23. One end of the air delivery pipe 17 is connected to the air inlet holes, and the other end is connected to the storage cylinder 23.

[0042] The storage cylinder 23 is used to store water and is also a gas collection device. The storage cylinder 23 is connected to the circulating water pipe 14, ensuring a continuous supply of water required during electrolysis and effectively collecting the gas generated by electrolysis. The end plate 19 is provided at both ends of the electrolytic tank 13, and its main function is to fix the internal components and ensure airtightness. By screwing the double-sided pull screw 21, the end plate 19 can be rotated to approach or move away from each other by rotating the pull screw 21, thereby achieving the extrusion and sealing of the internal insulation sealing cylinder 22 and the electrode plate 20. The electrode plate 20 includes the cathode plate 24 and the anode plate 29, and these electrode plates 20 are the core of the electrolysis reaction. The flow-through hole 30 in the middle of the electrode plate 20 ensures that water can flow freely between each electrode plate 20, providing the necessary medium for the electrolysis reaction. The cathode plate 24 and the anode plate 29 are arranged alternately to form the positive and negative electrodes required by the electrolysis environment. This alternating layout not only improves the reaction efficiency, but also maximizes the reduction of direct contact between the cathode and the anode, thereby avoiding short circuits and improving the efficiency of electrolysis. The first connecting piece 25 is located at the top of the cathode plate 24, connecting all cathode plates 24, ensuring the consistency and integrity of the cathode plate 24. By connecting the negative electrode of the power supply through the negative electrode connector 26, it helps to build an effective current path and enhance the efficiency of electrolysis. The second connecting piece 28 is also located at the top of the anode plate 29, connecting all anode plates 29. It is connected to the positive electrode of the power supply through the positive electrode connector 27, ensuring the stability of the consistent performance of the anode during the electrolysis process, and helping to improve the energy efficiency and reaction rate of the system. The water delivery pipe 18 is used to connect the storage cylinder 23 and the water inlet hole, responsible for delivering water in the storage cylinder 23 to the electrode plate 20, ensuring water supply during electrolysis, thereby supporting the electrolysis reaction.
