Description

Technical Field

[0001] This utility model relates to the technical field of drinking water treatment, specifically to a mineral water concentration control device and system. Background Technology

[0002] Most existing household or commercial water purification equipment uses processes such as reverse osmosis to produce near-pure water. While removing harmful substances, it also removes beneficial minerals such as calcium, magnesium, and potassium that the human body needs. To improve this situation, some equipment has added mineralization filters to perform post-mineralization of the pure water.

[0003] However, traditional mineralization methods have significant drawbacks: First, the mineral release rate of mineralization filter cartridges is greatly affected by water temperature, flow rate, and usage time, resulting in unstable effluent concentration that continues to decline as the filter cartridge's lifespan decreases, leading to uncontrollable mineral content and large fluctuations in the final drinking water quality. Second, individual filter cartridges must be replaced after performance degradation, affecting continuous use and making it impossible to predict when replacement will ensure adequate concentration. Furthermore, existing technologies struggle to flexibly and precisely formulate compound mineral water containing multiple specific minerals at a constant concentration, failing to meet users' personalized health drinking water needs. Therefore, the market urgently needs a water treatment device capable of real-time monitoring, automatic adjustment, and flexible concentration control of mineral concentration. Utility Model Content

[0004] The purpose of this invention is to provide a mineral water concentration control device that enables real-time monitoring and automatic adjustment of mineral concentration.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mineral water concentration regulating device, comprising: The water tank is regulated and contains mineral water, and a detection module is installed on one side of it; The mineralization filter element assembly is connected to the regulating water tank via a first pipeline and is used to generate mineral water; The diversion pipe assembly has its inlet end connected to the pure water inlet, its first outlet end connected to the mineralization filter element assembly through the first diversion pipe, and its second outlet end connected to the regulating water tank through the second diversion pipe. The diversion pipe assembly is configured to selectively guide pure water to the mineralization filter assembly or directly to the regulating water tank.

[0006] In a further technical solution, the diversion pipe assembly includes a first solenoid valve, which is a three-way valve, with its three ports respectively connected to the water inlet, the first diversion pipe, and the second diversion pipe.

[0007] In a further technical solution, the mineralization filter element assembly includes at least two mineralization filter element bodies arranged in parallel, and the inlet end of each mineralization filter element body is connected to the first diversion pipe through a second pipeline.

[0008] In a further technical solution, the mineralization filter element assembly also includes a second solenoid valve, which is disposed at the connection between the first diversion pipe and the second pipeline, and is used to control the flow of pure water into any of the mineralization filter element bodies.

[0009] A further technical solution is to install a flow meter on the first diversion pipe to measure the volume of water flowing through it.

[0010] In a further technical solution, the detection module includes a TDS detection probe that extends into the control tank.

[0011] In a further technical solution, the outlet of the regulating water tank is connected to the outlet via an outlet pipe.

[0012] A mineral water concentration control system, characterized in that it includes at least two mineral water concentration control devices; The outlets of each of the aforementioned control devices are connected to a common outlet via pipelines.

[0013] In a further technical solution, the mineral water concentration control device has its mineralized filter element filled with mineral balls or natural mineral stones of different mineral types.

[0014] In summary, this utility model has the following beneficial effects: Through real-time feedback from the TDS detection module and closed-loop control of the solenoid valve, dynamic and precise adjustment of the concentration in the water tank is achieved, effectively overcoming the defect of unstable water output of traditional mineralized filter cartridges and ensuring consistent water quality.

[0015] The parallel mineralization filter design, combined with a flow meter for cumulative metering and automatic switching, ensures that the mineral water entering the system always originates from a filter with good performance. This provides a stable and high-concentration basis for precise control from the source and solves the problem of inaccurate system benchmarks caused by the decay of a single filter.

[0016] Convenient maintenance and uninterrupted operation: The "hot backup" mechanism of the dual-filter parallel connection allows for seamless switching to the other filter when one is depleted, significantly extending the overall maintenance cycle. Users do not need to replace filters frequently, while ensuring continuous operation of the equipment and improving the user experience.

[0017] Flexible and scalable: The modular design allows multiple control devices to be connected in parallel, with each device independently responsible for the addition and control of one type of mineral. This enables the flexible formulation of compound mineral water with controllable total concentration and mineral ratio, meeting diverse healthy drinking water needs. Attached Figure Description

[0024] like Figure 1 As shown, a mineral water concentration regulating device includes at least one regulating water tank 20, which can always maintain a mineral water content of 100ml. A mineralization filter element assembly is connected to one side of the regulating water tank 20. The working principle of the mineralization filter element assembly is that pure water flows through the mineralization filter element assembly, dissolving the minerals therein to form a high-concentration mineral water (essentially a concentrated solution or mother liquor used to regulate the mineral concentration in the regulating water tank 20). This mineral water is then sent into the regulating water tank 20 and mixed with directly injected pure water to regulate the mineral concentration. A diversion pipe assembly is also provided on the other side of the regulating water tank 20. The diversion pipe assembly can connect the mineralization filter element assembly and the regulating water tank 20 respectively, for delivering pure water to the mineralization filter element assembly or the regulating water tank 20 respectively. A detection module 11 is provided on one side of the regulating water tank 20 for real-time detection of the TDS value in the regulating water tank 20. The regulating water tank 20 is connected to the water outlet 21.

[0025] In one embodiment, the diversion pipe assembly is connected to the inlet 10. The diversion pipe assembly includes a first solenoid valve 12, a first diversion pipe 13, and a second diversion pipe 19. The second diversion pipe 19 is connected to the regulating water tank 20, and the first diversion pipe 13 is connected to the mineralization filter element assembly. The first solenoid valve 12 is located at the three-way connection point of the inlet 10, the first diversion pipe 13, and the second diversion pipe 19. The first solenoid valve 12 is a three-way solenoid valve.

[0026] Specifically, pure water flows through inlet 10 and is controlled by the first solenoid valve 12 to either the first diversion pipe 13 or the second diversion pipe 19. For example, when pure water needs to be added to the regulating water tank 20, the first solenoid valve 12 controls the pure water in inlet 10 to flow to the second diversion pipe 19 before entering the regulating water tank 20. When the mineral content needs to be increased, the first solenoid valve 12 controls the connection between inlet 10 and the first diversion pipe 13, allowing the pure water in inlet 10 to flow to the first diversion pipe 13 and supply it to the mineralization filter assembly. The mineralization filter assembly then mineralizes the pure water before it flows to the regulating water tank 20.

[0027] The mineralized filter element assembly includes at least one mineralized filter element body 17, which is connected to the regulating water tank 20. The mineralized filter element body 17 is filled with specific natural mineral stones or mineral balls, such as maifan stone, wood fish stone, calcium balls, strontium balls, potassium balls, selenium balls, vanadium balls, zinc balls, etc. The appropriate mineral balls can be filled according to actual needs. When pure water flows through, the trace elements in the mineral stones will slowly and controllably dissolve into the pure water, thereby forming mineral water. The mineralized filter element body 17 is connected to the regulating water tank 20 through the first pipe 18.

[0028] Specifically, in this embodiment, the mineralization filter element assembly can be configured in multiple stages in parallel. For example, in this embodiment, two stages of mineralization filter elements are configured in parallel. There are two mineralization filter element bodies 17, which are configured in parallel. The water inlet ends of both mineralization filter element bodies 17 are connected to a second pipe 16. The second pipe 16 is connected to a first diversion pipe 13. A second solenoid valve 15 is installed at the connection between the first diversion pipe 13 and the second pipe 16 to control the flow of pure water into one of the two mineralization filter element bodies 17.

[0029] A mineralizing filter cartridge is essentially a mineral dissolving source. Its mineralizing capacity will naturally decrease as the usage time or the amount of water flowing through it increases. If only a single filter cartridge is used, the mineral concentration of the water will continue to decrease, resulting in inaccurate base concentration of the entire subsequent control system. The core purpose of the parallel design is to seamlessly switch to another filter cartridge with good performance when the performance of one filter cartridge deteriorates, so as to always provide the system with mineral water of "qualified concentration".

[0030] In one embodiment, a flow meter 14 is provided inside the first diversion pipe 13 to record the flow rate or volume of water passing through the mineralization filter element.

[0031] Specifically, the combination of flow meter 14 and second solenoid valve 15 ensures "source stability" of mineral water concentration. For example, taking the parallel configuration of two-stage mineralization filter cartridges in this embodiment as an example, the system defaults to using a single-stage mineralization filter cartridge, such as the attached... Figure 1The mineralization filter on the left is the primary filter and the one on the right is the secondary filter. The flow meter 14 continuously monitors the cumulative water output. When the water output reaches a preset value, it means that the performance of the mineralization filter may have degraded to a critical point. The control module will instruct the second solenoid valve 15 to switch, close the primary inlet and open the secondary inlet, so that pure water flows into the other mineralization filter body 17 and a fresh secondary mineralization filter is used. This ensures that the mineral water input into the mineral water tank is always maintained at a high concentration within an effective range, providing a reliable basis for subsequent precise TDS control. Moreover, the parallel connection of the two filters is equivalent to extending the effective working time of the system by nearly double. Users do not need to replace the first filter when it just degrades, but can wait until both filters are exhausted before maintaining them together. This avoids the trouble of frequent filter replacement, reduces maintenance frequency, and improves the ease of use and user satisfaction of the product. Alternatively, when one filter cartridge needs to be switched or even malfunctions, another filter cartridge can immediately take over, and the entire device does not need to be shut down, ensuring uninterrupted supply of mineral water and avoiding the downtime issues during filter cartridge replacement in traditional single-cartridge solutions.

[0032] In one embodiment, the regulating water tank 20 is connected to the water outlet 21 via the water outlet pipe 22.

[0033] In one embodiment, the detection module 11 is a TDS detection probe, and a portion of the TDS detection probe extends into the regulating water tank 20.

[0034] Specifically, TDS refers to the total content of all dissolved inorganic salts and organic matter in water. These dissolved substances usually exist in ionic form and mainly include: calcium ions, magnesium ions, sodium ions, potassium ions, bicarbonate ions, chloride ions, sulfate ions, and other trace minerals and ions. The TDS detection probe actually calculates the TDS value indirectly by measuring the water's conductivity. Because pure water is almost non-conductive, and the more dissolved mineral ions in the water, the higher the conductivity, and the higher the calculated TDS value. For a single controlled water tank, the TDS value directly and linearly reflects the concentration of that specific mineral ion. By monitoring the TDS value of the tank in real time, the control module can determine whether the current mineral concentration is too high or too low, and thus issue a command to control the operation of the first solenoid valve 12, determining whether pure water flows into the mineralization filter assembly or directly into the controlled water tank, thereby regulating the mineral concentration in the mineral water tank and achieving concentration stability. For example: When the TDS value is less than the preset threshold lower limit, the probe will send a low concentration signal back to the controller. The controller will then issue a command to directly connect the first solenoid valve to the water inlet and the mineralization filter assembly, thereby regulating the replenishment of mineral water in the water tank.

[0035] When the TDS value exceeds the preset threshold limit, the probe sends a high concentration signal back to the controller. The controller then issues a command to directly connect the first solenoid valve to the inlet and the regulating tank, injecting pure water into the regulating tank for dilution.

[0036] In one embodiment, multiple control devices can be connected in parallel to form a control system, such as... Figure 1 As shown, the upper and lower control devices are connected in parallel. For example, when it is necessary to control the concentration of mineral A and mineral B, the relevant material of mineral A can be filled into the device located at the upper and lower parts of the device. Figure 1 In the two upper mineralization filter cartridges, mineral B is placed in the... Figure 1 The two mineralization filter cartridges at the bottom can meet the requirements for regulating the concentration of two minerals. Multiple cartridges can also be set in parallel as needed, depending on the type of mineral to be regulated. Then, the water outlet pipe 22 is connected in parallel to the water outlet 21.

[0037] The method of using this mineral water concentration control device is as follows: S1. System initialization and mineral water preparation: The device is powered on, and the control system starts.

[0038] In the initial state, the first solenoid valve 12 is controlled to open the passage between the inlet 10 and the first diversion pipe 13, while the second solenoid valve 15 is controlled to open the passage between the first diversion pipe 13 and one of the mineralization filter elements 17, for example, to open the primary mineralization filter element.

[0039] Pure water flows in through inlet 10, passes through first solenoid valve 12, first diversion pipe 13, and second solenoid valve 15, and enters the designated mineralization filter element.

[0040] When pure water flows through the natural mineral stones inside the mineralized filter element, mineral ions dissolve in the water, forming mineral water of a specific concentration.

[0041] The generated mineral water is transported to the regulating water tank 20 through the first pipeline 18. Then, the first solenoid valve 12 is switched to connect the inlet 10 and the second diversion pipe 19, and pure water is injected until the liquid level in the tank reaches and is maintained at a preset capacity of about 100ml.

[0042] S2. Real-time concentration monitoring and feedback control: The TDS detection module 11 installed in the regulating water tank 20 starts working, detecting the TDS value of the mineral water in the tank in real time, and continuously sending the data to the control module.

[0043] The control module compares the received real-time TDS value with a preset concentration threshold range, and performs the following closed-loop control based on the comparison result: When the TDS value is lower than the preset threshold, it indicates that the mineral concentration is too low. The control module determines that high-concentration mineral water needs to be added and then issues a command to switch the first solenoid valve 12 to the state of connecting the inlet 10 and the first diversion pipe 13. At the same time, the second solenoid valve 15 guides the mineralization filter cartridge in use to start the mineral water replenishment process, that is, return to the mineral water preparation process in step S1 until the TDS value rises back to the preset range.

[0044] When the TDS value exceeds the preset threshold, it indicates that the mineral concentration is too high. The control module determines that dilution is required. It then issues a command to switch the first solenoid valve 12 to connect the inlet 10 and the second diversion pipe 19, directly injecting pure water into the regulating water tank 20 for dilution until the TDS value drops to the preset range.

[0045] S3. Parallel switching and maintenance of mineralized filter elements: During the continuous preparation of mineral water, the flow meter 14 measures the cumulative volume of water flowing through the currently used mineralized filter cartridge in real time.

[0046] The control module has a pre-stored preset value for the rated water treatment capacity of this type of filter element. When the cumulative water volume recorded by the flow meter 14 reaches this preset value, the control module determines that the mineralization capacity of the current mineralization filter element is approaching its decay point.

[0047] The control module then sends a switching command to the second solenoid valve 15 to close the passage to the current mineralization filter element body and open the passage to another parallel, unused mineralization filter element body, for example, defined as a secondary mineralization filter element.

[0048] The purified water is then switched to a new mineralization filter, which continues to provide mineral water of the correct concentration, thus achieving a "hot backup" function that allows for seamless switching without shutdown and ensuring the stability of the mineral water source concentration.

[0049] S4. Mineral water output and multi-channel distribution: The mineral water with a stable concentration after regulation is stored in the regulating water tank 20 and can be output from the water outlet 21 through the water outlet pipe 22 at any time according to the user's needs.

[0050] When it is necessary to prepare compound drinking water containing multiple minerals, multiple of the aforementioned control devices are connected in parallel. Each device is independently responsible for the generation and concentration control of one mineral, such as calcium or magnesium.

[0051] The outlets 21 of each device are connected to a common mixer or final outlet via pipelines. By independently controlling the operation of each device, a compound healthy drinking water with controllable and adjustable mineral ratio and total concentration is finally output.
