Description

Technical Field

[0001] This application relates to the technical field of hydrogen water preparation, and more particularly to a hydrogen water preparation control system. Background Technology

[0002] Hydrogen water, as a beverage with health benefits, has attracted increasing attention for its preparation technology, and various hydrogen water preparation devices are gradually being applied to daily production and life. Currently, traditional hydrogen water preparation devices are usually simply assembled from a water supply unit, an electrolysis hydrogen production unit, and a water output unit. However, they have obvious defects in actual use: First, the linkage control mechanism between water supply and hydrogen production is lacking. Most devices require manual start-up of the hydrogen production unit or use a timed start-up method, which cannot respond in real time according to the actual water supply situation. This can easily lead to problems such as the hydrogen production unit running dry when the water supply is insufficient, or the hydrogen production unit failing to start in time despite continuous water supply, resulting in water waste. Second, the water supply pipeline lacks an effective backflow prevention protection structure. When the system pressure fluctuates, the electrolyzed water or gas in the hydrogen water generation component can easily flow back into the drinking water supply pipeline, which may not only contaminate the drinking water source but also cause corrosion damage to the water supply component. Utility Model Content

[0003] The purpose of this utility model embodiment is to provide a hydrogen water preparation control system that can solve the above-mentioned problems existing in the prior art.

[0004] To achieve the above objectives, this application adopts the following technical solution: On one hand, a hydrogen water preparation control system is provided, comprising: a direct drinking water supply component, a hydrogen water generating component, a water storage device, and a water intake component. The direct drinking water supply component is connected to the inlet of the hydrogen water generating component via a pipe, and a first one-way valve and a sensor switch are sequentially arranged on the pipe. The sensor switch is electrically connected to the hydrogen water generating component. When the sensor switch detects water flow in the pipe, the sensor switch opens and triggers the hydrogen water generating component to start. The outlet of the hydrogen water generating component is connected to the inlet of the water storage device, and the outlet of the water storage device is connected to the water intake component.

[0005] Furthermore, the hydrogen-water generating assembly includes a hydrogen-water generator and a control board. The control board is electrically connected to the sensor switch and the hydrogen-water generator, respectively. The control board controls the hydrogen-water generator to start electrolysis by acquiring the sensing signal from the sensor switch.

[0006] Furthermore, a drain outlet is provided on the bottom side of the hydrogen water generator, which is used to discharge exhaust gas and wastewater.

[0007] Furthermore, a second one-way valve is provided at the drain outlet.

[0008] Furthermore, the water storage tank is equipped with a liquid level detection component, which is electrically connected to the control board. The liquid level detection component is used to detect the liquid level of hydrogen water in the water storage tank and transmit the liquid level signal to the control board. When the liquid level is lower than a preset lower limit, the control board controls the sensor switch to remain open to continuously supply water for hydrogen production; when the liquid level reaches a preset upper limit, the control board controls the sensor switch to close to stop supplying water for hydrogen production.

[0009] Furthermore, the hydrogen water generating assembly also includes a hydrogen concentration detector, which is installed on the outlet pipe of the hydrogen water generator. The hydrogen concentration detector is electrically connected to the control board. The hydrogen concentration detector is used to detect the concentration of the electrolyzed hydrogen and transmit the concentration signal to the control board. When the hydrogen concentration is lower than a preset concentration value, the control board controls the hydrogen water generator to increase the electrolysis power; when the hydrogen concentration reaches the preset concentration value, the control board controls the hydrogen water generator to maintain the current electrolysis power or reduce the electrolysis power.

[0010] Furthermore, it also includes a pressure detector and a pressure relief valve. The pressure detector is located inside the hydrogen water generator, and the pressure relief valve is located on the top of the hydrogen water generator. The pressure detector and the pressure relief valve are electrically connected to the control board. The pressure detector is used to detect the pressure value inside the hydrogen water generator and transmit the pressure signal to the control board. When the pressure value exceeds a preset safe pressure value, the control board controls the pressure relief valve to open and release pressure. When the pressure value drops to a safe range, the control board controls the pressure relief valve to close.

[0011] Furthermore, the water intake assembly includes a water intake device and a metering solenoid valve, wherein the metering solenoid valve is disposed on the pipeline between the water outlet of the water storage device and the water intake device.

[0012] Furthermore, it also includes a scale cleaning component, which includes a cleaning solution storage tank and a cleaning pump. The cleaning solution storage tank is connected to the water inlet of the hydrogen water generator through a cleaning pipe. The cleaning pump is installed on the cleaning pipe and is electrically connected to the control board. When cleaning is required, the control board controls the cleaning pump to start, pumping the cleaning solution in the cleaning solution storage tank into the hydrogen water generator for scale cleaning. The waste liquid after cleaning is discharged through the drain outlet.

[0013] Furthermore, the water storage device is also equipped with a temperature regulating component, which is used to regulate the temperature inside the water storage device.

[0014] The beneficial effects of this application are as follows: Compared with traditional manual or timed start-up methods, the sensor switch can detect the water flow status in the pipeline in real time, realizing linkage control of starting when water is available and stopping when water is not available. When the water supply is insufficient, the sensor switch does not trigger the start signal, which can prevent the hydrogen-water generating component from being damaged by dry burning due to idling and circuit failure; when the water supply is continuous, hydrogen production can be started immediately, avoiding the waste of water resources caused by direct drinking water flowing out without hydrogen production, and improving the efficiency of energy and water resource utilization.

[0015] Meanwhile, the first check valve strictly restricts water flow to the hydrogen water generator only from the drinking water supply end. When the system pressure fluctuates, the check valve will automatically close and seal, preventing electrolytic residual water and hydrogen from the hydrogen water generator from flowing back into the drinking water supply pipeline. This avoids contamination of the drinking water source by electrolysis byproducts and prevents backflow liquid from causing electrochemical corrosion to the drinking water supply component, extending the overall service life of the equipment and improving operational safety.

[0016] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0019] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0022] like Figure 1 As shown, this embodiment provides a hydrogen water preparation control system, including: a direct drinking water supply component 1, a hydrogen water generating component 2, a water storage tank 3, and a water intake component 4. The direct drinking water supply component 1 is connected to the water inlet of the hydrogen water generating component 2 through a pipeline, and a first one-way valve 5 and a sensor switch 6 are sequentially arranged on the pipeline. The sensor switch 6 is electrically connected to the hydrogen water generating component 2. When the sensor switch 6 detects water flow in the pipeline, the sensor switch 6 opens and triggers the hydrogen water generating component 2 to start. The water outlet of the hydrogen water generating component 2 is connected to the water inlet of the water storage tank 3, and the water outlet of the water storage tank 3 is connected to the water intake component 4.

[0023] Based on the above scheme, after the direct drinking water supply component 1 is turned on, the direct drinking water flows into the connecting pipe under pressure. First, it passes through the first one-way valve 5, allowing only one-way flow from the direct drinking water end to the hydrogen water generating component 2. When the water flows through the sensor switch 6 on the pipe, the sensor switch 6 detects the water flow signal and immediately closes the circuit, sending a start electrical signal to the hydrogen water generating component 2. The hydrogen water generating component 2 then starts the electrolysis hydrogen production process. After hydrogen production is completed, the hydrogen gas produced by electrolysis and the electrolyzed water flow into the water storage tank 3 through the outlet pipe. Under the pressure inside the water storage tank 3, they are further fully dissolved to form stable hydrogen-rich water. When the user operates the water dispensing component 4, the hydrogen-rich water in the water storage tank 3 flows out directly for use. If the water supply is interrupted, the sensor switch 6 is opened, and the hydrogen water generating component 2 stops operating simultaneously.

[0024] The hydrogen water preparation control system has a simple and compact structure. It only requires the addition of a first one-way valve 5 and a sensor switch 6 to the connecting pipe between the drinking water supply component 1 and the hydrogen water generating component 2. It does not require additional complex control modules, mechanical linkage mechanisms or auxiliary protection devices. This simplifies the overall assembly process, reduces the cost of parts procurement and manufacturing, and lowers the difficulty of production and subsequent maintenance.

[0025] In terms of functionality, a simplified linkage mechanism is constructed through the direct electrical connection between the sensor switch 6 and the hydrogen-water generator component 2. This eliminates the need for manual intervention or complex timing control programs, enabling precise response by starting when water is available and stopping when water is unavailable. This effectively avoids the problems of idling and dry burning of the hydrogen production unit and water waste caused by poor coordination between water supply and hydrogen production in traditional equipment, thus improving the efficiency of energy and water resource utilization. The first one-way valve 5, with its unidirectional mechanical structure, reliably prevents electrolytic residual water and hydrogen from flowing back into the drinking water supply pipeline during system pressure fluctuations without additional power. This avoids contamination of the drinking water source by electrolysis byproducts, ensuring drinking water safety, and also prevents backflow liquid from causing electrochemical corrosion to the drinking water supply component 1, extending the overall service life of the equipment. While optimizing core functions, it also considers structural simplicity and cost-effectiveness, making it more suitable for large-scale applications in daily production and life. Meanwhile, the water storage unit 3 uses its own pressure to further dissolve hydrogen and water, eliminating the need for an additional hydrogen dissolving device. This simplifies the structure while improving the hydrogen dissolution rate, ensuring stable output hydrogen-rich water concentration and better quality. It balances functional optimization and cost-effectiveness, making it suitable for large-scale applications.

[0026] Generally, the hydrogen water generating assembly 2 includes a hydrogen water generator 201 and a control board 202. The control board 202 is electrically connected to the sensor switch 6 and the hydrogen water generator 201. The control board 202 controls the hydrogen water generator 201 to start electrolysis by acquiring the sensing signal from the sensor switch 6. When the drinking water supply assembly 1 supplies water, the water flow in the pipeline triggers the sensor switch 6, which transmits the water flow detection signal to the control board 202 of the hydrogen water generating assembly 2. After receiving and recognizing the sensing signal, the control board 202 generates a control command through preset control logic and sends a start signal to the hydrogen water generator 201. The hydrogen water generator 201 then starts the electrolysis hydrogen production process. If the water supply is interrupted, the sensor switch 6 stops sending signals, and the control board 202, not receiving any signals, sends a stop command, and the hydrogen water generator 201 stops operating. The control board 202 establishes an indirect yet precise control link between the sensor switch 6 and the hydrogen generator 201. Compared to a direct electrical connection, the control board 202 can filter and process the sensor signals, preventing accidental start / stop of the hydrogen generator 201 due to water flow fluctuations or signal interference, thus improving control stability. Furthermore, the control board 202 can integrate more control logic, such as electrolysis power adjustment and running time monitoring, providing refined control of the hydrogen generator 201 and ensuring the efficiency and safety of hydrogen production through electrolysis. This structure achieves functional upgrades simply by adding a conventional control board 202, without adding complex mechanical components, thus improving control performance while maintaining system simplicity and cost-effectiveness.

[0027] Preferably, the hydrogen water generator 201 has a drain outlet on its bottom side for discharging waste gas and wastewater. During the electrolysis process of hydrogen production, in addition to generating hydrogen gas for preparing hydrogen-rich water, the hydrogen water generator 201 may also generate a small amount of residual waste gas that has not participated in the dissolution, such as trace amounts of oxygen or other gases. At the same time, some wastewater to be discharged will be formed after electrolysis, such as residual water containing electrolysis byproducts. Since the drain outlet is located on the bottom side of the hydrogen water generator 201, gravity can be used to smoothly discharge the accumulated waste gas and wastewater to an external collection or treatment device by opening the drain outlet during equipment operation intervals or periodic maintenance. The drain outlet design can promptly remove residual waste gas and wastewater from the hydrogen water generator 201, preventing waste gas accumulation from causing abnormal internal pressure or affecting the efficiency of the electrolysis reaction. At the same time, it prevents electrolysis byproducts contained in the wastewater from adhering to the electrode surface, causing corrosion or contamination of the subsequently generated hydrogen water, thus ensuring the quality of hydrogen water and the stability of the equipment's electrolysis performance. The bottom layout conforms to the law of gravity drainage, eliminating the need for additional power drainage components. The sewage discharge function can be achieved through a simple drain outlet structure, which simplifies the internal design of the hydrogen water generator 201 and reduces the equipment manufacturing cost and maintenance difficulty.

[0028] A second one-way valve 203 is installed at the drain outlet. The second one-way valve 203, located at the drain outlet on the bottom side of the hydrogen-water generator 201, has a valve core and sealing structure that allows the medium to flow unidirectionally from the inside of the hydrogen-water generator 201 to the outside. When exhaust gas and wastewater need to be discharged, the internal pressure of the hydrogen-water generator 201 pushes the valve core of the second one-way valve 203 to open, and the exhaust gas and wastewater are discharged through the drain outlet. When discharge stops or the internal pressure of the hydrogen-water generator 201 is lower than the external pressure, the valve core of the second one-way valve 203 automatically closes and seals under its own elastic force or external pressure, preventing the reverse flow of external medium.

[0029] The second one-way valve 203 effectively prevents backflow and pressure interference at the drain outlet. On one hand, it prevents external air, sewage, or impurities from flowing back into the hydrogen generator 201 through the drain outlet, thus preventing corrosion and contamination of the electrolysis components and avoiding impurities affecting the purity and quality of the hydrogen. On the other hand, it prevents external pressure fluctuations from being transmitted to the hydrogen generator 201, ensuring stable internal pressure during the electrolytic hydrogen production process and preventing abnormal pressure from affecting hydrogen generation efficiency and the solubility with water. Furthermore, this one-way valve has a simple structure and can achieve automatic one-way flow without additional control components. While improving the reliability of equipment operation, it does not increase system complexity or cost, conforming to the overall design philosophy of simplicity and economy.

[0030] In some embodiments, the water storage tank 3 is equipped with a liquid level detection component, which is electrically connected to the control board 202. The liquid level detection component is used to detect the liquid level of hydrogen water in the water storage tank 3 and transmit the liquid level signal to the control board 202. When the liquid level is lower than a preset lower limit, the control board 202 controls the sensor switch 6 to remain open to continuously supply water for hydrogen production. When the liquid level reaches a preset upper limit, the control board 202 controls the sensor switch 6 to close to stop supplying water for hydrogen production. The liquid level detection components inside the water tank 3 (such as float level sensors, ultrasonic level gauges, etc.) monitor the liquid level of hydrogen water in the water tank 3 in real time and convert the continuous liquid level signal into an electrical signal and transmit it to the control board 202. The control board 202 has a built-in preset upper and lower limit logic for liquid level. When the received liquid level signal shows a height lower than the preset lower limit, it is determined that there is insufficient hydrogen water in the water tank 3. The control board 202 outputs a command to keep the sensor switch 6 open, the drinking water supply component 1 continues to supply water, and the hydrogen water generating component 2 produces hydrogen synchronously. Hydrogen water continuously flows into the water tank 3 until the liquid level rises. When the liquid level signal shows a height reaching the preset upper limit, it is determined that the water tank 3 is full. The control board 202 outputs a command to close the sensor switch 6, the drinking water supply is interrupted, and the hydrogen water generating component 2 stops producing hydrogen to prevent the liquid level from continuing to rise.

[0031] Furthermore, the hydrogen-water generating assembly 2 also includes a hydrogen concentration detector, which is installed on the outlet pipe of the hydrogen-water generator 201. The hydrogen concentration detector is electrically connected to the control board 202. The hydrogen concentration detector is used to detect the concentration of electrolyzed hydrogen and transmit the concentration signal to the control board 202. When the hydrogen concentration is lower than a preset concentration value, the control board 202 controls the hydrogen-water generator 201 to increase the electrolysis power; when the hydrogen concentration reaches the preset concentration value, the control board 202 controls the hydrogen-water generator 201 to maintain the current electrolysis power or reduce the electrolysis power. The hydrogen concentration detector of the hydrogen water generating component 2 is installed in the outlet pipe of the hydrogen water generator 201. It detects the hydrogen concentration in the hydrogen water (a mixture of hydrogen and water after electrolysis) flowing through the pipe in real time and converts the concentration detection signal into an electrical signal, which is then transmitted to the control board 202. The control board 202 has a built-in preset hydrogen concentration threshold logic. When the received concentration signal is lower than the preset concentration value, it is determined that the current hydrogen content of the hydrogen water is insufficient. The control board 202 outputs a command to make the hydrogen water generator 201 increase the electrolysis power (such as increasing the electrolysis current / voltage) to increase the hydrogen generation rate. When the concentration signal reaches the preset concentration value, it is determined that the hydrogen water quality meets the requirements. The control board 202 outputs a command to make the hydrogen water generator 201 maintain the current electrolysis power (to maintain a stable concentration) or reduce the electrolysis power (to avoid energy waste), ensuring that the hydrogen concentration is stable within the target range.

[0032] Additionally, a pressure detector and a pressure relief valve are included. The pressure detector is located inside the hydrogen-water generator 201, and the pressure relief valve is located on the top of the hydrogen-water generator 201. Both the pressure detector and the pressure relief valve are electrically connected to the control board 202. The pressure detector detects the pressure value inside the hydrogen-water generator 201 and transmits the pressure signal to the control board 202. When the pressure value exceeds a preset safe pressure value, the control board 202 controls the pressure relief valve to open and release pressure. When the pressure value drops to a safe range, the control board 202 controls the pressure relief valve to close. The pressure detector, installed inside the hydrogen-water generator 201, monitors the internal pressure changes in real time and converts the pressure signal into an electrical signal, which is then transmitted to the control board 202. The pressure relief valve, located on the top of the hydrogen-water generator 201, is electrically connected to the control board 202 to receive control commands. The control board 202 has a built-in preset safety pressure value. When the received pressure signal displays a value that exceeds the preset safety pressure value, it is determined that the internal pressure of the hydrogen generator 201 is overloaded. The control board 202 immediately outputs a command to control the pressure relief valve to open, releasing the excess internal pressure through the top channel. When the pressure detector detects that the pressure value has dropped to the preset safety range, the control board 202 sends a command to close the pressure relief valve, restoring the internal pressure of the hydrogen generator 201 to the normal pressure state and ensuring the continuous and stable operation of the electrolysis hydrogen production process.

[0033] This pressure detection and pressure relief protection mechanism provides reliable pressure safety for the hydrogen water generator 201. On the one hand, it can monitor and respond quickly to internal pressure anomalies in real time, avoiding safety risks such as deformation of the hydrogen water generator 201 shell, seal failure, or even rupture due to excessive pressure. It also prevents high pressure from affecting the stability of the electrolysis electrodes and the efficiency of hydrogen generation. On the other hand, the pressure relief valve is automatically opened and closed through the control board 202, eliminating the need for manual intervention. This improves the safety and automation of the equipment operation and reduces manual monitoring costs. Furthermore, both the pressure detector and the pressure relief valve are directly connected to the existing control board 202 system, eliminating the need for an additional independent pressure control loop. While strengthening safety protection functions, this does not increase system structural complexity or manufacturing costs, maintaining the overall simplicity and economical design advantages of the equipment.

[0034] Specifically, the water dispensing component 4 includes a water dispenser and a metering solenoid valve. The metering solenoid valve is installed on the pipeline between the outlet of the water storage tank 3 and the water dispenser. The metering solenoid valve in the water dispensing component 4 is connected in series on the pipeline between the outlet of the water storage tank 3 and the water dispenser, and it is linked with the system control logic, which can be achieved through the control board 202 or an independent trigger unit. When the user needs to dispense water, he operates the water dispenser, such as by pressing a button or touching the sensor, which triggers the metering solenoid valve to open. The metering solenoid valve controls the valve opening time or opening degree according to the preset water output parameters (such as 200ml, 500ml, etc.), so that the hydrogen-rich water in the water storage tank 3 flows to the water dispenser through the pipeline. When the outflow reaches the preset metering value, the metering solenoid valve automatically closes, terminating the water supply and completing one metered water dispensing process.

[0035] Optionally, the system also includes a scale removal assembly, which comprises a cleaning solution storage tank and a cleaning pump. The cleaning solution storage tank is connected to the inlet of the hydrogen water generator 201 via a cleaning pipe. The cleaning pump is mounted on the cleaning pipe and is electrically connected to the control board 202. When cleaning is required, the control board 202 controls the cleaning pump to start, pumping the cleaning solution from the storage tank into the hydrogen water generator 201 for scale removal. The waste liquid after cleaning is discharged through the drain outlet. The cleaning solution storage tank of the scale removal assembly is connected to the inlet of the hydrogen water generator 201 via a cleaning pipe, and the cleaning pump is connected in series with the cleaning pipe and electrically connected to the control board 202. When the hydrogen water generator 201 needs to be cleaned of scale after long-term use, the user can trigger the cleaning command on the control board 202, such as by manually pressing a button or by setting a timer program. The control board 202 will then output a signal to start the cleaning pump. When the cleaning pump is running, it generates negative pressure, which draws the descaling cleaning solution (such as food-grade citric acid solution) from the cleaning solution storage tank and pumps it into the hydrogen water generator 201. The cleaning solution fully contacts and reacts with the scale attached to the inner wall and electrodes of the generator. After the cleaning is completed, the control board 202 can control the cleaning pump to stop. At the same time, the drain port on the bottom side of the hydrogen water generator 201 opens, and the waste liquid after the reaction is discharged through the drain port under the action of gravity, completing the entire scale cleaning process.

[0036] This scale removal component provides a convenient and efficient maintenance solution for the hydrogen water generator 201. On the one hand, it can periodically remove scale (calcium carbonate and other impurities) generated on the electrodes and inner walls during electrolysis, preventing scale buildup from increasing electrolysis resistance and energy consumption, ensuring the hydrogen water generator 201 maintains high electrolysis efficiency, and preventing scale from detaching and contaminating the hydrogen water quality. On the other hand, the cleaning process is automated through the control board 202, eliminating the need for manual disassembly of the equipment, significantly reducing the complexity and labor costs of maintenance operations. Furthermore, the cleaning component connects to the existing hydrogen water generator 201 via simple pipes and a pump, and reuses the original drain outlet structure, requiring no large-scale modifications to the main system. While achieving scale removal, it also maintains structural simplicity and cost-effectiveness, further enhancing the long-term value and practicality of the equipment.

[0037] In an optional embodiment, the water reservoir 3 is further equipped with a temperature regulation component, which is used to regulate the temperature inside the water reservoir 3. The temperature regulation component on the water reservoir 3 typically includes a temperature detection unit (such as a temperature sensor) and a temperature control unit (such as a heating rod, a semiconductor cooling chip, etc.), and is electrically connected to the system control board 202. The temperature detection unit collects the temperature signal of the hydrogen-rich water inside the water reservoir 3 in real time and converts it into an electrical signal, which is then transmitted to the control board 202. The control board 202 has a built-in user-preset or system-default target temperature range (such as 25°C for room temperature, 45°C for warm temperature, 10°C for refrigeration, etc.). When the detected temperature is lower than the target lower limit, the control board 202 triggers the heating module in the temperature control unit to start, heating the hydrogen water inside the water reservoir 3; when the temperature is higher than the target upper limit, it triggers the cooling module (if configured) to start, cooling the water; when the temperature reaches the target range, the control board 202 controls the temperature regulation component to stop operating, maintaining a stable temperature of the hydrogen water inside the water reservoir 3.

[0038] This temperature control component significantly improves the user experience and quality stability of hydrogen-rich water. Firstly, it allows for flexible temperature adjustment based on user needs, catering to different drinking preferences in various scenarios (e.g., drinking warm hydrogen water in winter, chilled hydrogen water in summer, or drinking room-temperature hydrogen water directly), expanding the product's applicable scenarios. Secondly, the solubility of hydrogen in water is greatly affected by temperature. Maintaining the hydrogen water within a suitable solubility range through temperature control (e.g., higher hydrogen solubility at low temperatures) reduces hydrogen loss due to excessive heat, ensuring stable hydrogen content in the output hydrogen-rich water and enhancing the product's core efficacy. Furthermore, the temperature control component can be integrated into the housing or interior of the water reservoir 3, achieving automated temperature control through the existing control board 202. This eliminates the need for an additional independent control device, enriching functionality without compromising the simplicity of the overall system structure or significantly increasing manufacturing costs, aligning with the design principle of "balancing functional upgrades with economic practicality."
