Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of drinking water mineralization, and in particular to a device for regulating the pH value of mineralized water and a water dispenser. BACKGROUND

[0002] The pH value of drinking water has an important influence on human health and the stability of water supply systems. According to the "Drinking Water Health Standards" (GB 5749-2022), the pH value of drinking water should be strictly controlled between 6.5 and 8.5. This range not only effectively protects the digestive tract and mucous membrane tissues of the human body from irritation, but also reduces the corrosiveness of water to metal pipelines, preventing the dissolution of heavy metal ions such as iron, lead, and copper, thereby ensuring water quality safety. However, in actual applications, in order to increase the mineral content of drinking water, many water purification devices use alkaline filter materials such as maifanite and limestone for mineralization treatment. Such filter materials, while releasing beneficial ions such as calcium and magnesium, also tend to cause the pH value of the outlet water to rise, even exceeding the upper limit of 8.5, posing potential health and safety risks.

[0003] In order to solve this problem, the industry currently generally uses carbon dioxide acidification method to adjust the pH value. This method injects carbon dioxide gas (CO2) into water to generate carbonic acid to neutralize alkalinity, with the advantages of rapid reaction and no introduction of external chemicals. However, this technology also exposes a series of problems in actual operation. First, CO2 gas needs to be continuously supplied, and gas cylinders need to be replaced frequently, resulting in high operating costs. Second, the solubility of CO2 is greatly affected by temperature and pressure, resulting in unstable pH adjustment accuracy and the risk of over-adjustment or under-adjustment. In addition, the reaction between CO2 and calcium and magnesium ions in water may generate carbonate precipitates, causing pipeline blockage or filter material scaling, further increasing the difficulty of system maintenance and operation risk.

[0004] More importantly, most current water purification devices lack a pH regulation system that can dynamically respond to changes in water quality, does not require chemical addition, and has low operating costs. Traditional methods rely on fixed filter material combinations or intermittent dosing, making it difficult to achieve real-time monitoring and precise adjustment of the pH value. This technical gap is particularly prominent in small household water purifiers, community centralized water supply systems, and remote water supply projects. In these application scenarios, water quality may fluctuate seasonally, and the system itself lacks sufficient intelligent control capabilities, resulting in unstable pH control and affecting overall water purification effectiveness and water quality safety.

[0005] Therefore, a technical solution is needed to provide a low-cost, chemical-free, real-time adjustment capable dynamic pH regulation device that can improve mineralization effectiveness while ensuring that the outlet water pH value always falls within the national standard range, balancing water quality health and pipeline safety.

[0045] The pH value of drinking water is one of the important indicators for measuring water quality safety. According to the "Drinking Water Health Standards" (GB5749-2022), the pH value should be strictly controlled between 6.5 and 8.5. This range not only guarantees the friendliness to human health, but also effectively reduces the corrosion and scaling risk of the water supply pipe network system. If the pH value is too low, the water is acidic, which may irritate the mucous membrane system of the human body and dissolve heavy metal ions in the pipeline; while the pH value is too high, the water body is alkaline, which affects the taste, and long-term drinking may interfere with the normal acid-base balance of the human body.

[0046] In actual water purification process, in order to improve the mineralization of water, improve the taste and supplement trace elements, many water purification equipment use alkaline filter material for treatment. However, it is found that during operation, the filter material soaked in water for a long time will continuously release alkaline substances, causing the pH value of the effluent to gradually increase, even exceeding the upper limit of 8.5, which brings the risk of substandard water quality. Especially in the case of slow water flow or long equipment downtime, this phenomenon is more obvious.

[0047] At present, the common solution includes using CO2 gas for acidification adjustment, which neutralizes the alkaline components in water by generating carbonic acid. Although this method has certain adjustment effect, there are many problems in actual application: first, CO2 gas source needs to be continuously supplied, which increases the operation cost and management complexity; second, the solubility of CO2 in water is greatly affected by temperature and pressure, resulting in low pH adjustment accuracy and poor stability; in addition, CO2 may react with minerals in water to form carbonate precipitates, which may block the pipeline or affect the subsequent treatment process.

[0048] Therefore, the present application proposes a device for regulating the pH value of mineralized water and a water dispenser, which realizes real-time dynamic pH regulation at low cost and without chemical addition, can ensure that the pH value of the effluent is always within the national standard range while improving the mineralization effect, and balances water quality health and pipe network safety. According to the embodiment, through the linkage control of liquid level and concentration, the dilution process is accurately managed; through pure water dilution instead of chemical regulation, the risk of secondary pollution is effectively avoided; through real-time monitoring and closed-loop regulation of pH value, the stability and consistency of water quality output are ensured, which not only improves the operation efficiency and water quality safety guarantee ability of the equipment, but also provides a more healthy and convenient direct drinking mineralized water solution for users, and has good application prospect and popularization value.

[0049] The example embodiments of the present application will be described below with reference to the accompanying drawings.

[0050] Figure 1 A schematic diagram of a device for regulating the pH value of mineralized water according to an example embodiment is shown.

[0051] Referring to Figure 1 , a device for regulating the pH value of mineralized water is shown, which is arranged at the end of the purified water supply pipe 1, and the device includes a diversion valve 3, a mineralization unit 5, a mixed water tank 8, a pH value detection unit 9, a liquid level sensor 12 and a water outlet valve 15.

[0052] According to some embodiments, the switching valve 3 is connected to the purified water supply pipe 1, and connects the purified water supply pipe 1 to the first pipe 4 or the second pipe 10. The device uses the switching valve 3 to intelligently switch the connection between the purified water supply pipe 1 and the first pipe 4 (mineralization path) or the second pipe 10 (bypass path), and can automatically adjust the water flow direction according to actual needs, ensuring that the purified water can be accurately guided to the corresponding processing path in different operation stages (such as mineralization and dilution processes), thereby improving the automation level of the system and enhancing the flexibility and efficiency of the processing process. Specifically, in the mineralization stage, the switching valve 3 guides the purified water to the mineralization filter element for necessary mineral addition to improve water quality and adjust the pH value; and in the dilution stage, the switching valve 3 switches the water flow to directly enter the water tank to adjust the overall water quality to the ideal pH range. In this way, the system can effectively manage water quality without using chemical additives, ensuring water quality and avoiding possible secondary pollution problems.

[0053] According to some embodiments, the mineralization unit 5 is arranged on the first pipe 4 to pass the purified water through a mineralization filter element, thereby mineralizing the purified water to obtain primary mineralized water. Specifically, the mineralization unit 5 is arranged on the first pipe 4 for mineralization treatment of the purified water. When the purified water flows through the pipe, it will first pass through a mineralization filter element containing specific proportions of mineral components (such as calcium, magnesium, and other alkaline minerals). These minerals can be slowly released into the water, increasing the pH value of the water while supplementing the water body with trace elements beneficial to the human body, thereby converting pure water, which is acidic, into primary mineralized water with certain alkalinity and mineral content.

[0054] According to some embodiments, the mineralization unit 5 includes a filter material with a containing cavity and an alkaline filter element 6 filled in the containing cavity, so that the purified water passes through the alkaline filter element 6 and the filter material in sequence, wherein the filter material includes: carbonaceous rocks, artificial ceramic materials. Specifically, when the purified water enters the mineralization unit 5, it flows through the alkaline filter element 6 and the filter material in sequence, and through physical contact with the mineral components therein, the mineralization treatment of the water quality is realized. The filter material is composed of carbonaceous rocks (such as calcite, limestone, etc.) and artificial ceramic materials. These materials have good stability and moderate solubility, and can slowly release calcium, magnesium, and other minerals beneficial to the human body when the water flows through, thereby increasing the pH value of the water and enhancing the taste of the water. Among them, the carbonaceous rocks mainly play the role of adjusting the carbonate balance in the water and increasing the alkalinity; while the artificial ceramic materials have a porous structure, which not only can assist in adjusting the uniformity of the water flow, but also have certain adsorption and slow-release functions, which are helpful to maintain the long-term stability of the water quality. The mineralization unit 5 uses a physical mineralization method, which can convert pure water into primary mineralized water rich in minerals without the need for chemical additives, is safe and environmentally friendly, and is suitable for household and commercial water purification systems.

[0055] According to some embodiments, the mineralization process of the device does not require the addition of any chemical agent, relying on the contact of natural minerals with water to achieve a safe and stable functionalization treatment. This physical type of mineralization not only avoids the risk of secondary pollution, but also effectively improves the taste of the water, making it closer to the quality of natural mineral water. Therefore, the mineralization unit 5, as the key module in the system for realizing the functionalization of water quality, provides a basic guarantee for the subsequent dilution regulation and water stability.

[0056] According to some embodiments, the first pipeline 4 and the second pipeline 10 are respectively connected to the water mixing tank 8, which is used to accommodate and mix the primary mineralized water and the purified water. Specifically, the first pipeline 4 and the second pipeline 10 are respectively connected to the water mixing tank 8 for introducing the water flow from different treatment stages into the tank for mixing. Among them, the first pipeline 4 transports the primary mineralized water treated by the mineralization unit 5, which has a higher pH value and contains a certain amount of minerals; while the second pipeline 10 transports purified water (such as reverse osmosis water) without mineralization treatment, which usually has a neutral pH value. The water mixing tank 8, as the core mixing unit in the system, is responsible for receiving and containing the water flow from the two paths, and promoting the full mixing of the two by structural design or built-in stirring device. Through this double-path water supply combined with the water mixing tank 8, the ideal drinking pH range can be achieved without adding any chemical reagent, relying only on the proportion adjustment between the primary mineralized water and the purified water, which not only improves the safety and environmental protection of the system, but also enhances the stability and controllability of the water quality, meeting the high standard demand of users for healthy drinking water.

[0057] According to some embodiments, the pH value detection unit 9 is arranged at the bottom of the water mixing tank 8 for monitoring the pH value of the liquid inside the tank. Since the pH value of the mixed mineralized water and purified water directly affects the water quality standard of the final effluent after mixing in the water mixing tank 8, placing the detection unit at the bottom can more accurately obtain the water body information after mixing, ensuring that the detection result is representative. The liquid level sensor 12 is arranged above the liquid surface inside the water mixing tank 8 for monitoring the liquid level. Through the liquid level sensor 12, the current water storage capacity can be grasped in real time, and the start and stop of the water inlet electromagnetic valve and the switching of the working state of the diverter valve 3 can be controlled accordingly. For example, in the mineralization stage, the dilution process is started according to the preset liquid level, and the water inlet is stopped when the total liquid level is reached, thereby ensuring that the entire water production process runs efficiently and stably according to the set logic. The cooperative work of these two types of sensor components not only improves the intelligent level of the system, but also ensures the stability and safety of the effluent water quality.

[0058] According to some embodiments, the device further comprises a controller, the pH detection unit 9 and the liquid level sensor 12 are electrically connected to the controller, the controller is electrically connected to the pH detection unit 9 and the liquid level sensor 12, and is responsible for receiving real-time monitoring signals from the two sensors. By analyzing these signals, the controller can determine whether the pH value of the liquid in the mixing tank 8 meets the standard and whether the liquid level reaches the set value, and make corresponding control decisions accordingly.

[0059] According to some embodiments, the controller is electrically connected to the diverter valve 3, and the controller controls the diverter valve 3 so that the purified water supply pipe 1 is connected to the first pipe 4 or the second pipe 10. Specifically, the controller is further electrically connected to the diverter valve 3 and can automatically control the working state of the diverter valve 3 according to a preset program. For example, at the beginning of the mineralization stage, the controller drives the diverter valve 3 to switch the purified water supply pipe 1 to the first pipe 4 (mineralization path) so that the water flows through the mineralization unit 5 to generate primary mineralized water; when the liquid level reaches the set height, the controller controls the diverter valve 3 to switch to the second pipe 10 (bypass path) to introduce non-mineralized water for dilution adjustment, thereby achieving precise control of the final effluent water quality. The automatic control of the diverter valve 3 by the controller realizes intelligent management of the whole process from water source switching, mineralization treatment, mixing regulation to effluent preparation, which not only improves the stability and response speed of the equipment operation, but also effectively ensures that the effluent water quality is always within a safe and healthy range.

[0060] According to some embodiments, the device further comprises a water inlet electromagnetic valve 2, which is arranged on the purified water supply pipe 1 and located before the diverter valve 3. The control end of the water inlet electromagnetic valve 2 is electrically connected to the controller, and the controller controls the communication or shutdown of the water inlet electromagnetic valve 2. The water inlet electromagnetic valve 2 is used to control the on-off of purified water to ensure that the water flow enters the subsequent processing link according to the system set process. The control end of the water inlet electromagnetic valve 2 is electrically connected to the controller and is managed by the controller. During operation, the controller determines whether water is needed according to the data fed back by the liquid level sensor 12 and the pH detection unit 9, and realizes precise regulation and control of the water flow by controlling the opening or closing of the water inlet electromagnetic valve 2. For example, at the beginning of the mineralization or dilution stage, the controller issues an instruction to open the electromagnetic valve to make purified water flow into the system; when the mixing tank 8 reaches the preset liquid level or the effluent pH value reaches the target range, the controller closes the electromagnetic valve to stop water inflow to prevent overflow or water quality exceeding the standard. This linkage control mechanism not only improves the automation level of the system, but also helps to save energy and water, and ensures the safety and stability of the equipment operation.

[0061] Figure 2 A schematic diagram of a controller control method for regulating the pH value of mineralized water according to an example embodiment is shown.

[0062] According to some embodiments, referring to Figure 2 , the controller is optionally configurable to calculate a first liquid level according to the pH value range of the direct drinking mineralized water set by the user and the pH value monitoring data from the pH value detection unit 9, and control the switching valve 3 to communicate with the first pipeline 4 to deliver the primary mineralized water to the first liquid level in the water mixing tank 8. Specifically, the controller dynamically adjusts the system operation state according to the pH value range of the direct drinking mineralized water set by the user (e.g., 7-8.5) in combination with the real-time monitoring data from the pH value detection unit 9. When the pH value of the liquid in the water mixing tank 8 is detected to be lower than the lower limit of the set range or the device is in the initial start-up stage, the controller controls the switching valve 3 to switch to the first pipeline 4 (mineralization path) to preferentially introduce the primary mineralized water into the water mixing tank 8 to prevent the initial pH value from being too low and ensure the stability of the water quality.

[0063] According to some embodiments, the controller is further configurable to control the switching valve 3 to communicate with the second pipeline 10 to deliver the purified water to a second liquid level in the water mixing tank 8 according to the current liquid level data from the liquid level sensor 12 when the current liquid level data is equal to the first liquid level. When the liquid level sensor 12 feeds back that the current liquid level reaches the preset first liquid level (i.e., the filling of the primary mineralized water is completed), the controller determines that the dilution stage is entered and issues an instruction to switch the switching valve 3 to the second pipeline 10 (bypass path) to start injecting the purified water without mineralization into the water mixing tank 8 to adjust the overall pH value and raise the liquid level.

[0064] According to some embodiments, the controller is further configurable to control the water inlet electromagnetic valve 2 to be turned off to cut off the inflow of the purified water according to the current liquid level data from the liquid level sensor 12 when the current liquid level data is equal to the second liquid level. Further, when the liquid level sensor 12 detects that the current liquid level rises to the preset second liquid level (i.e., the target value of the total liquid level), the controller closes the water inlet electromagnetic valve 2 to cut off the water supply to prevent overflow, and controls the switching valve 3 to switch back to the first pipeline 4 to prepare for the next working cycle.

[0065] Through the above control strategy, the controller realizes the automatic switching and closed-loop management of key processes such as mineralization, dilution, and shutdown. This control method based on the dual feedback mechanism of pH value and liquid level not only improves the response accuracy and operation efficiency of the system, but also effectively ensures that the output water quality is always within a safe and healthy range, and is widely applicable to high-quality drinking water treatment needs in family, office, and commercial scenarios.

[0066] Referring to Figure 1 , based on the law of conservation of hydrogen ions, the mixing ratio of mineralized water and pure water is derived as follows:

[0067] [H+] 总 (V1+V2)=[H + ]1V1+[H + ]2V2

[0068] Since c[H + ]=10^(-pH), assuming the pH of the lye mineral water is a, the pH of the pure water is 7, let the lye mineral water be supplemented to the water tank to the liquid level height H1, the water tank is supplemented to the height H2, the bottom area of the water tank is S, and the height is H 总 , V 总 =S(H1+H2).

[0069] The pH of the mineral water after release is b, and the range value is 7-8.5.

[0070] Then:

[0071] 10^(-b)S(H1+H2)=10^(-a)SH1+10^(-7)(SH2)

[0072] Solving the equation gives the mixing ratio of mineral water and pure water:

[0073]

[0074] Since H 总 =H1+H2, b=8.5, that is:

[0075]

[0076] Where H1 ranges from 0 to H 总 .

[0077] Specifically, during the mineralization stage, the water inlet electromagnetic valve 2 is opened, and the steering valve 3 is connected to the first pipeline 4 (mineralization path). The purified water is mineralized through the filter core 6, and the primary mineralized water is injected into the water mixing tank 8 through the water inlet 7. The pH sensor 9 is used for real-time monitoring, and the pH value of the alkaline primary mineralized water is obtained, recorded as a, and H1 is calculated:

[0078]

[0079] The liquid level is monitored by the liquid level sensor 12 until the liquid level reaches H1 (i.e., the first liquid level height) calculated as above.

[0080] When the liquid level reaches the preset H1, the reversing valve 3 switches to the second pipeline 10 (i.e. the bypass path); the purified water is directly injected into the water tank through the water inlet 11 to dilute the primary mineralized water to the total liquid level Htotal (i.e. the second liquid level height). After mixing, the pH sensor 9 measures that the pH value is reduced to b≤8.5, meeting the water outlet requirements. The controller controls the water inlet electromagnetic valve 2 to close, stops water inlet, and switches the reversing valve to the first pipeline 4, waiting for the next mineralization.

[0081] According to some embodiments, the controller can be further configured to: according to the current liquid level height data from the liquid level sensor 12, when the current liquid level height data is less than and / or equal to a third liquid level height, control the water inlet electromagnetic valve 2 to be in communication. The controller intelligently judges according to the current liquid level height data fed back by the liquid level sensor 12 to ensure that the water tank 8 always maintains an appropriate water level range, avoiding affecting the subsequent water stability or device operation abnormally due to the water level being too low. Specifically, when the controller receives the current liquid level height data detected by the liquid level sensor 12 and judges that the data is less than or equal to the set third liquid level height, it indicates that the water quantity in the water tank 8 has dropped to a critical value that needs to be replenished. At this time, the controller will control the water inlet electromagnetic valve 2 to open, and the water inlet process of the next cycle is carried out. This control mechanism realizes the dynamic adjustment of the water quantity in the water tank 8, ensuring the continuous and stable progress of the mineralization process. By setting a reasonable third liquid level height threshold, the device can maintain efficient operation while avoiding energy waste and equipment wear caused by frequent start-stop, thereby improving the intelligent level and operation reliability of the entire device.

[0082] According to some embodiments, the device further comprises a water supply indicator light electrically connected to the controller. When the water inlet electromagnetic valve 2 is closed and the pH value monitoring data is within the set pH value range, the water supply indicator light is controlled to turn on to prompt the user that the current is a water taking state. The water supply indicator light is electrically connected to the controller and can switch states according to the instructions of the controller. The controller not only controls the opening and closing of the water inlet electromagnetic valve 2, but also has the comprehensive judgment ability of water quality parameters. When the controller detects that the water inlet electromagnetic valve 2 is in the closed state, it indicates that the current water treatment process has been completed and the device enters the standby state. At this time, the controller will further judge whether the real-time pH value is within the preset pH value range to confirm whether the water quality meets the use requirements. When the water inlet electromagnetic valve 2 is closed and the real-time pH value is within the set range, the controller will trigger the water supply indicator light to turn on as a prompt signal to the user. This prompt indicates that the device is in a water taking state at this time, and the user can safely take water. In this way, the user does not need to actively check the display screen or perform additional operations to quickly judge whether it is suitable to take water at the moment, improving the intelligent level and use convenience of the equipment.

[0083] According to some embodiments, the water outlet valve 15 is arranged at the bottom of the mixing tank 8 for externally delivering the direct drinking mineralized water with a set pH value range. Specifically, the water outlet valve 15 is arranged at the bottom of the mixing tank 8 for controlling the output of the direct drinking mineralized water after the mineralization and pH adjustment treatment. Optionally, the opening and closing of the valve can be intelligently controlled by the controller, or a button control can be designed, or a manual valve can be adopted, and the user can choose according to the actual scene.

[0084] According to some embodiments, in order to improve the water outlet efficiency and meet the water supply demand in different use scenarios, the device further comprises a water supply pump 14 arranged between the water outlet valve 15 and the mixing tank 8 to provide power for externally delivering the direct drinking mineralized water. The user triggers the water taking signal (such as a manual valve, a control button, etc. as described above), starts the water supply pump 14, and the mineralized water is output through the water outlet 15, and the pH value is stabilized at 7-8.5. Generally, the water supply pump 14 is arranged in the pipeline between the water outlet valve 15 and the mixing tank 8, and mainly functions to provide stable power for the external delivery of the direct drinking mineralized water, so as to ensure that the water flow can be smoothly and quickly delivered to the user end, such as a drinking water faucet, a water storage container or other subsequent water equipment. The water supply pump 14 is electrically connected with the controller, and can realize automatic start-stop control according to the running state of the device. For example, when the controller judges that the water quality meets the set standard and opens the water outlet valve 15, the water supply pump 14 will also be started to assist in completing the efficient water outlet process. When the water quality does not meet the standard or the system is in standby state, the water pump remains closed to avoid unnecessary energy consumption and water flow disturbance.

[0085] According to some embodiments, the technical solution of the present application can also be applied to the design of a water dispenser, which comprises the device as claimed in any one of the above, so that the water dispenser can realize real-time dynamic pH regulation at low cost and without chemical addition, improve the mineralization effect, and ensure that the outlet water pH value is always within the national standard range, taking into account water quality health and pipe network safety.

[0086] According to some embodiments, the technical solution of the present application realizes dynamic intelligent adjustment of the dilution ratio of the mineralized water by introducing a liquid level-concentration combined control model. The controller comprehensively analyzes the liquid level data collected by the liquid level sensor 12 and the concentration information detected online, adjusts the ratio of the purified water for dilution and the primary mineralized water in real time, and ensures that the final output water quality is stable within the target range, which not only improves the response speed and adjustment accuracy of the system, but also effectively avoids the water quality fluctuation problem that may occur in the traditional fixed ratio dilution mode, and improves the automation level and operation stability of the entire device.

[0087] According to some embodiments, the technical solution of the present application discards the CO2 or other acidic chemical reagents commonly used in traditional acidification to adjust the pH value, and realizes the adjustment of the pH value of the mineralized water by dilution with pure water. This method not only ensures the water quality adjustment effect, but also effectively avoids the potential pollution risk caused by the introduction of chemical additives, eliminates the by-products or residues that may be produced, and ensures that the final effluent is truly weak alkaline water. In addition, the cancellation of the chemical addition link also helps to simplify the structure, reduce the maintenance cost, and improve the environmental protection and sustainable operation ability of the equipment.

[0088] According to some embodiments, the technical solution of the present application can realize real-time monitoring of the acid-base degree of the mineralized water throughout the process by configuring a high-precision pH sensor, and form a closed-loop feedback mechanism with the controller. Once the pH value deviates from the set range, the controller can immediately start the corresponding adjustment measures (such as adjusting the dilution ratio or controlling the water supply state), so as to realize online regulation and integrated management of water quality, significantly improve the response ability of the device to water quality changes, ensure that the output water quality is always in a safe, stable and drinkable state, and enhance the safety and reliability of user use.

[0089] According to some embodiments, the technical solution of the present application realizes precise management of the dilution process through the linkage control of liquid level and concentration; effectively avoids the secondary pollution risk by replacing chemical regulation with pure water dilution; ensures the stability and consistency of water quality output through real-time monitoring and closed-loop adjustment of the pH value, not only improves the operation efficiency and water quality safety guarantee ability of the equipment, but also provides a more healthy and convenient direct drinking mineralized water solution for users, and has good application prospect and popularization value.
