Description

Technical Field

[0001] This utility model relates to the field of drinking water mineralization technology, specifically to a device and water dispenser for supplementing and purifying water with mineral elements. Background Technology

[0002] Minerals in drinking water, such as calcium, magnesium, zinc, strontium, and metasilicic acid, are essential for human health. When ingested in appropriate amounts, these minerals can promote bone development, enhance immunity, regulate electrolyte balance, and support neuromuscular function, among other physiological functions.

[0003] However, while traditional mineralization filter technology provides these essential minerals, it often suffers from cost issues such as excessive mineral leaching, substandard mineral concentration in the effluent, shortened filter life, and increased costs. For example, when mineralization filter materials are immersed in water for extended periods, excessive leaching of mineral ions may occur in some cases, causing the concentration of certain minerals in the drinking water to exceed the tolerable upper intake level (UL). This can lead to the risk of specific mineral poisoning, especially for children, the elderly, or individuals with specific health conditions, where excessive intake can pose a significant health threat. Generally, different countries and regions have set strict upper and lower limits for the mineral content in drinking water to ensure public health and safety. However, with traditional technologies, due to fluctuations in raw water quality and changes in the performance of the filter materials themselves, it is often difficult to guarantee that the mineral concentration in the effluent consistently meets these regulatory requirements. Furthermore, a higher rate of mineral leaching not only leads to excessive mineral concentration in the effluent but also accelerates the aging process of the filter materials, shortening their lifespan. This means users need to replace the filter more frequently, increasing the long-term economic burden. The reduced filter lifespan and increased replacement frequency directly lead to higher maintenance costs. In addition, considering environmental factors, frequent filter replacements are not conducive to the effective use of resources and environmental protection.

[0004] Furthermore, traditional technologies typically employ simple mineralization methods or post-mixing to replenish minerals in drinking water. These methods lack flexibility and struggle to effectively address the gradual decline in filter performance over time, as well as natural fluctuations in raw water quality. Therefore, in practical applications, it is difficult to achieve precise control over mineral concentration, thus affecting the stability of the final effluent quality.

[0005] Therefore, a technical solution is needed that can accurately control the mineral concentration of the effluent, extend the service life of the filter element, adapt to changes in different water quality conditions, better meet people's needs for healthy drinking water, and reduce the cost and environmental impact of long-term use.

[0036] Minerals in drinking water, such as calcium, magnesium, zinc, strontium, and metasilicic acid, are essential for human health. When ingested in appropriate amounts, these minerals can promote bone development, enhance immunity, regulate electrolyte balance, and support neuromuscular function, among other physiological functions.

[0037] However, while traditional mineralization filter technology provides these essential minerals, it often suffers from cost issues such as excessive mineral leaching, substandard mineral concentration in the effluent, shortened filter life, and increased costs. For example, when mineralization filter materials are immersed in water for extended periods, excessive leaching of mineral ions may occur in certain situations, causing the concentration of some minerals in the drinking water to exceed the tolerable upper intake level (UL). This can lead to the risk of specific mineral poisoning, especially for children, the elderly, or individuals with specific health conditions, where such excessive intake can pose a significant health threat.

[0038] Generally, different countries and regions have set strict upper and lower limits for the mineral content in drinking water to ensure public health and safety. However, with traditional technologies, due to fluctuations in raw water quality and changes in the performance of the filter material itself, it is often difficult to guarantee that the mineral concentration of the effluent consistently meets these regulatory requirements. Furthermore, a higher rate of mineral leaching not only leads to excessive mineral concentration in the effluent but also accelerates the aging process of the filter material, shortening its lifespan. This means users need to replace the filter more frequently, increasing the long-term economic burden. The reduced lifespan of the filter and the increased replacement frequency directly lead to higher maintenance costs. In addition, considering environmental factors, frequent filter replacements are also detrimental to the efficient use of resources and environmental protection.

[0039] Furthermore, traditional technologies typically employ simple mineralization methods or post-mixing to replenish minerals in drinking water. These methods lack flexibility and struggle to effectively address the gradual decline in filter performance over time, as well as natural fluctuations in raw water quality. Therefore, in practical applications, it is difficult to achieve precise control over mineral concentration, thus affecting the stability of the final effluent quality.

[0040] Therefore, this application proposes a device and water dispenser for supplementing mineral elements in purified water. It is widely applicable to the adjustment of beneficial mineral elements in household, community, or industrial water purification equipment. It can regulate the mineral elements in the effluent, precisely controlling the concentration of minerals in the effluent, extending the lifespan of the filter cartridge, and adapting to changes in water quality conditions. This better meets people's needs for healthy drinking water while reducing long-term operating costs and environmental impact. According to the embodiment, by installing an ion sensor and flow meter on the purified water inlet pipe, combined with a mineralization filter cartridge, a three-way mixing structure, and a flow control valve, precise regulation of the mineral concentration in direct-drinking mineralized water is achieved. The system employs dual ion concentration monitoring, combined with real-time flow data, and the flow management controller dynamically adjusts the flow distribution ratio coefficient to ensure stable and compliant effluent water quality.

[0041] Before describing the embodiments of this application, some terms or concepts involved in the embodiments of this application will be explained.

[0042] PID control is a feedback control mechanism widely used in industrial control systems. It adjusts the controller's output by calculating the error between the setpoint (target value) and the actual output value, thereby achieving precise control. The PID controller gets its name from the three mathematical operations it uses: proportional (P), integral (I), and derivative (D).

[0043] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of this application.

[0044] Figure 1 A schematic diagram of an apparatus for replenishing mineral elements in purified water is shown according to an example embodiment.

[0045] See Figure 1 The figure shows a device for replenishing mineral elements in purified water. The device is located at the end of the purified water inlet pipe 1. The device includes: a first ion sensor 2, a flow control valve 3, a second ion sensor 8, a three-way valve 10, and a mineralization filter element 7.

[0046] According to some embodiments, the first ion sensor 2 is installed on the purified water inlet pipe 1 to monitor the ion concentration in the purified water and obtain a first ion concentration parameter. This first ion concentration parameter reflects the basic mineral level in the raw water and is an important reference for subsequent mineralization treatment and flow distribution adjustment. Through the first ion sensor 2, the system can dynamically monitor the inlet water quality and intelligently regulate it in conjunction with the target effluent concentration to ensure that the final output mineralized water meets safety and nutritional standards.

[0047] According to some embodiments, the flow control valve 3 is located after the first ion sensor 2 and connected to the purified water inlet pipe 1, dividing the purified water into a first pipe 4 and a second pipe 5. The flow control valve 3 is used to divide the monitored purified water into the first pipe 4 and the second pipe 5 according to a set ratio. The flow control valve 3 can be dynamically adjusted according to the flow distribution ratio coefficient calculated by the system to ensure that the amount of water entering the mineralization filter element 7 (second pipe 5) and the amount of water passing directly through (first pipe 4) are precisely matched.

[0048] According to some embodiments, the mineralization filter element 7 is disposed on the second pipeline 5 so that the purified water passes through the mineralization filter element 7, thereby mineralizing the purified water to obtain primary mineralized water. The mineralization filter element 7 is disposed in the second pipeline 5 to perform mineralization treatment on the purified water flowing through the pipeline, thereby converting the purified water, which originally contained no or very low amounts of minerals, into primary mineralized water. The mineralization filter element 7 typically contains a variety of soluble mineral materials (such as maifanite, tourmaline, mineralized balls, etc.), which can release mineral ions beneficial to the human body (such as calcium, magnesium, potassium, etc.), improve the taste of the water and enhance its nutritional properties.

[0049] According to some embodiments, the second ion sensor 8 is disposed in the second pipeline 5, after the mineralization filter element 7, to monitor the ion concentration of the primary mineralized water and obtain a second ion concentration parameter. The second ion sensor 8 is disposed in the second pipeline 5, after the outlet end of the mineralization filter element 7, to monitor the ion concentration in the primary mineralized water after mineralization treatment in real time, thereby obtaining the second ion concentration parameter. This parameter reflects the actual working effect of the mineralization filter element 7, that is, the increase in mineral concentration of the purified water after flowing through the mineralization material.

[0050] According to some embodiments, in some customized scenarios, the operating status and mineralization efficiency of the mineralization filter element 7 can also be determined through continuous monitoring by the second ion sensor 8. If the second ion concentration parameter is detected to deviate from the set value, it can be determined whether the distribution ratio of the flow control valve 3 needs to be adjusted, the user needs to be reminded to replace or regenerate the mineralization filter element 7, or other control units can be linked to perform closed-loop regulation to ensure the stability and safety of the final effluent water quality.

[0051] According to some embodiments, the first pipe 4 and the second pipe 5 are connected to the tee 10 to deliver stable concentration of direct-drinking mineralized water. Specifically, the second pipe 5 contains primary mineralized water treated by the mineralization filter 7, which has a high mineral content; the second pipe 5 also contains unmineralized purified water, retaining its original low ion concentration characteristics. After the two water flows converge at the tee 10, they are physically mixed to form direct-drinking mineralized water with a moderate mineral concentration, good taste, and meeting the target water quality standards.

[0052] According to some embodiments, the mixing process is based on a system-preset flow distribution ratio (adjusted by the flow control valve 3) and real-time ion concentration parameters collected by the first ion sensor 2 and the second ion sensor 8, achieving closed-loop control of the final effluent mineral concentration. In some scenarios requiring precise control, the mixing ratio can be calculated and dynamically adjusted through intelligent algorithms, effectively addressing fluctuations in influent water quality and ensuring that the output water quality remains at the set value, meeting the needs for safe and healthy drinking water.

[0053] During system operation, the mineralization effect and the stability of the effluent quality can be controlled by adjusting the water flow rate entering the second pipeline 5 (controlled by the aforementioned flow control valve 3). The primary mineralized water output will be mixed with the unmineralized purified water in the first pipeline 4 in subsequent stages to achieve precise control of the final effluent mineral concentration.

[0054] According to some embodiments, the device further includes: a first flow meter and a second flow meter, wherein the first flow meter is installed on the purified water inlet pipe 1 to monitor the current total flow rate of the purified water; the second flow meter is installed on the first pipeline 4 or the second pipeline 5 to monitor the current first flow rate of the first pipeline 4 or the second flow rate of the second pipeline 5. Specifically, the first flow meter is installed on the purified water inlet pipe 1 to monitor the total flow rate of purified water entering the system in real time, and can be used to calculate the flow rate of the second pipeline 5 required for mineralization treatment and the flow rate of the unmineralized portion of the first pipeline 4, and provide a basis for subsequent mixing ratio control. The second flow meter is installed in the first pipeline 4 or the second pipeline 5 to monitor the actual flow rate currently flowing through the pipeline. If installed in the second pipeline 5, it measures the amount of water entering the mineralization filter element 7; if installed in the first pipeline 4, it measures the amount of bypassed unmineralized water. Through the first and / or second flow data, the working state of the flow control valve 3 can be further calibrated, and the mixing ratio can be dynamically adjusted in conjunction with the first and second ion concentration parameters to ensure the stability of the final effluent water quality. The first and second flow meters, together with the aforementioned first and second ion sensors, constitute the system's multi-parameter sensing network, supporting closed-loop feedback control of the entire mineralization mixing process, thereby achieving precise regulation and continuous stable output of mineral concentration in direct drinking mineralized water.

[0055] According to some embodiments, the device further includes a flow management controller for controlling and adjusting the flow distribution ratio coefficient of the flow control valve 3, thereby regulating the flow of the first pipeline 4 and the second pipeline 5.

[0056] Figure 2 The diagram illustrates a flow management controller control method for an apparatus for replenishing mineral elements in purified water according to an example embodiment.

[0057] See Figure 2 The flow management controller is electrically connected to the flow control valve 3. It receives the monitored first ion concentration parameter and second ion concentration parameter based on the target effluent ion concentration set by the system and real-time sensor data. Based on the set direct drinking mineralized water ion concentration, it adjusts the flow distribution ratio coefficient of the flow control valve 3. It calculates and controls the flow distribution ratio coefficient of the flow control valve 3.

[0058] According to some embodiments, the adjustment formula for the flow control valve 3 is as follows:

[0059]

[0060] Where 'a' is the flow distribution ratio coefficient of the flow regulating valve, C1 is the first ion concentration parameter, C2 is the second ion concentration parameter, and C3 is the set ion concentration of the direct drinking mineralized water. Specifically, based on the target mixed effluent ion concentration C3, a mass conservation equation is established:

[0061]

[0062] Wherein, V1 is the flow rate of the first pipeline 4 (without passing through the mineralization filter element 7), and V2 is the flow rate of the second pipeline 5 (passing through the mineralization filter element 7).

[0063] The total flow rate is V 总 Then we have: V 总 =V1+V2, the flow split ratio of the first pipeline 4 is The flow split ratio obtained by the second pipeline 5 is: We derive that:

[0064] C3 = C1·a + C2·(1-a)

[0065] Solving the equation yields the flow distribution ratio coefficient:

[0066]

[0067] Based on the calculated value of 'a', the flow control valve 3 adjusts the flow ratio of the first pipeline 4 and the second pipeline 5.

[0068] According to some embodiments, when the first ion concentration parameter is equal to or greater than the set direct drinking mineralized water ion concentration, the flow distribution ratio coefficient of the flow regulating valve is set to 1, thereby allowing the purified water to be directly supplied as direct drinking mineralized water. That is, when C1≥C3, a=1, and the full flow enters the first pipeline 4 without mineralization treatment.

[0069] According to some embodiments, when the set direct-drinking mineralized water ion concentration is greater than or equal to the second ion concentration parameter, the flow distribution ratio coefficient of the flow regulating valve is set to 0, thereby directly supplying the primary mineralized water as direct-drinking mineralized water. That is, when C3≥C2, a=0, and the entire flow enters the second pipeline 5 for complete mineralization treatment.

[0070] When a∈(0,1), the first pipe 4 receives a proportionate flow rate, and the second pipe 5 receives a proportionate flow rate of (1-a). Furthermore, as can be seen from the above formula, the technical solution of this utility model can overcome the limitations of traditional fixed filter cartridges, achieving stability under water quality fluctuations. It can be fully automatically and intelligently adjusted according to actual scenario requirements, and is suitable for filter cartridges with high long-term soaking dissolution rates, solving the defects of the mineral materials themselves. It dynamically coordinates the release rate of minerals at different stages—initial, intermediate, and final—using an intelligent regulating valve to adjust the flow distribution ratio, achieving mineral replenishment without exceeding the set target value.

[0071] According to some embodiments, the ion concentration of the direct-drinking mineralized water is set based on the health needs of the population or using recommended concentrations or standard upper and lower limits. Specifically, the main ions in mineralized water, such as calcium, magnesium, potassium, and bicarbonate, not only affect the taste of the water but also have positive effects on human physiological functions, such as maintaining bone health, cardiovascular function, and nerve conduction. In practical applications, the ion concentration of direct-drinking mineralized water can be set according to the health needs of the population. Furthermore, adjustments can be made based on the physiological characteristics and health needs of different population groups. For example, children and the elderly have higher calcium requirements, while athletes may require more electrolyte supplementation. Therefore, in the mineralized water treatment process, the source water quality, treatment process, and population characteristics should be comprehensively considered to rationally set the ion concentration and maximize the health value of drinking water.

[0072] According to some embodiments, in the closed-loop control system, the controller continuously receives data from the first ion sensor 2, the second ion sensor 8, and the flow meter. Combined with preset water quality targets, it automatically adjusts the valve opening using a PID control algorithm or other intelligent control algorithms to ensure that the output water quality remains stable within the set range. Furthermore, the controller can also have functions such as fault diagnosis, filter life reminders, and abnormal water quality alarms, improving the system's automation level and user experience. The flow management controller, through precise adjustment of the flow control valve 3, achieves intelligent control of the mineralization mixing process, ensuring stable and safe control of the mineral concentration in the output direct-drinking mineralized water.

[0073] According to some embodiments, the flow management controller may be further configured to: receive the monitored total flow, the first flow, or the second flow, and calibrate the flow control valve 3 according to a currently set flow allocation ratio coefficient. The controller will then transmit the actually measured V... 总 If there is a deviation between V1 or V2 and the theoretical calculated value, it is judged as valve control error, pipeline blockage or other abnormal situation, and the flow control valve 3 is dynamically corrected accordingly to ensure that the actual distribution ratio is close to the target value.

[0074] Adjust the calibration formula for the flow control valve 3:

[0075]

[0076] Where 'a' is the flow distribution ratio coefficient of the flow control valve, and V 总 V1 represents the total flow rate, V2 represents the first flow rate, and V1 represents the second flow rate. If V1 or V2 deviates from the expected value due to factors such as water pressure fluctuations or changes in filter element resistance, the controller can automatically adjust the valve opening according to the formula to bring the actual flow rate back to the set value. The flow management controller can simultaneously integrate ion concentration data and flow rate data to achieve dual closed-loop control of "water quality + flow rate," improving system stability and response speed.

[0077] According to some embodiments, the flow management controller can also be configured to perform anomaly detection based on the flow rate of the first pipeline 4 (without mineralization filter 7) and the flow rate of the second pipeline 5 (with mineralization filter 7). If an anomaly is detected, such that V2 = 0 or V1 = V... 总 This may indicate that the mineralization pathway is completely blocked; if V1 or V2 > V 总 This could be due to a sensor malfunction. In some scenarios, the flow management controller can trigger an alarm, pause water output, or switch to a safety mode to prevent the output of substandard water. The overall structure is modular and the control is intelligent, featuring adaptive adjustment, fault diagnosis, and filter status monitoring, thus improving equipment safety, energy efficiency, and user experience.

[0078] According to some embodiments, the technical solution of this application can also be applied to the design of a system for supplementing mineral elements in purified water. The system includes: the device as described in any of the preceding claims, which enables the system to supplement mineral elements based on flow rate distribution, thereby achieving the adjustment of mineral elements in the effluent. This not only allows for precise control of the effluent mineral concentration but also extends the service life of the filter cartridge and adapts to changes in different water quality conditions. It is widely applicable to the formulation of beneficial mineral elements in household, community, or industrial water purification equipment, better meeting people's needs for healthy drinking water while reducing long-term usage costs and environmental impact.

[0079] According to some embodiments, the technical solution of this application achieves precise control of the mineral concentration of direct-drinking mineralized water by installing an ion sensor and a flow meter on the purified water inlet pipe 1, combined with the mineralization filter element 7, the three-way valve 10 mixing structure, and the flow control valve 3. The system adopts dual ion concentration monitoring (C1, C2), combined with real-time flow data (V 总 (V1 or V2), the flow distribution ratio coefficient (a) is dynamically adjusted by the flow management controller to ensure that the effluent water quality is stable and meets the standards.
