Description

Technical Field

[0001] This application relates to the field of mineralized water purification technology, and in particular to a control method, apparatus, mineralized water purification system and equipment for a mineralized water purification system. Background Technology

[0002] As residents' living standards improve, their demands for drinking water quality are increasing. Water purifiers with mineralization functions are widely favored because they can improve the taste of water and supplement minerals. Existing mineralization water purifiers usually use a mineralization filter filled with mineral particles as the last filter. However, when the machine is idle, the mineral particles continue to dissolve minerals into the water.

[0003] Current mineral water purifiers mostly use fixed-cycle backflow flushing control systems, lacking the ability to respond to dynamic factors such as filter lifespan and ambient temperature, resulting in lagging regulation. In the initial stages of filter use or under high-temperature environments, the mineral concentration of the first cup of water may exceed safe limits, posing a health risk. Conversely, in the later stages of filter use or under low-temperature environments, fixed-interval flushing wastes water and energy, and cannot guarantee the stability of the output water quality, affecting user experience and product safety. Summary of the Invention

[0022] Based on the current real-time time and the water intake behavior model, determine whether to perform a backflow flushing operation;

[0023] When it is determined that a backflow flushing operation will be performed, and the standby time is greater than the target time threshold, the mineral water in the mineralized filter cartridge is controlled to flow back to the reverse osmosis component of the mineralized water purification system for purification treatment.

[0027] The control component is connected to the power component, the conductivity monitoring unit and the return solenoid valve respectively;

[0046] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0047] In related technologies, the mineral dissolution concentration of mineralized filter cartridges initially increases and then decreases with the total purified water volume. Initially, the internal pores of the filter cartridge gradually open, increasing the contact area with water, resulting in a higher mineral concentration in the first cup of water after settling. Later, the mineral elements in the mineral particles are gradually consumed, leading to a decrease in dissolution concentration. Furthermore, the dissolution rate is also affected by temperature; higher temperatures result in faster dissolution and more significant concentration changes. Therefore, in existing mineralized water purification systems, the mineral concentration in the first cup of water may exceed safety limits during the initial use of the filter cartridge or in high-temperature environments, posing a health risk. Conversely, in later stages of filter cartridge use or in low-temperature environments, fixed-interval rinsing wastes water and energy resources and cannot guarantee the stability of the output water quality.

[0048] To address the aforementioned issues, this application provides a control method for a mineralized water purification system. This method enables the mineralized filter cartridge to be back-flushed and rinsed according to dynamically changing rinsing intervals, ensuring that the mineralized water purification system can provide users with a stable first cup of drinking water with consistent mineral concentrations under various environments.

[0049] The mineralized water purification system provided in this application embodiment is applied to a mineralized water purifier, that is, a water treatment device with water purification and mineralization functions. It is understood that in other embodiments, the mineralized water purifier may also have other functions, such as boiling water function, hot water dispensing function, etc., and there is no specific limitation; it can be selected according to actual needs.

[0050] Please see Figure 1 This application provides a control method for a mineralized water purification system, including steps 102, 104, 106 and 108.

[0051] Step 102: If the mineralized water purification system is in standby mode, obtain the standby duration and real-time conductivity value of the current reflux processing process.

[0052] Specifically, standby mode refers to a static mode that the mineral water purification system enters after the user stops drawing water. In practical applications, the mineral water purification system can enter standby mode in standby state or when it is turned off, in order to maintain the overall mineral concentration of the mineral water stored in the mineral filter cartridge within a preset range.

[0053] The current recirculation process refers to the logical processing process that completes one recirculation purification process in standby mode. For example, if the mineralized water purification system enters standby mode at 8:00 AM and completes one recirculation purification process at 10:30 AM, then the processing process of the mineralized water purification system within the time range of 8:00 AM to 10:30 AM constitutes one recirculation process.

[0054] Standby time refers to the duration during which the mineralized water purification system remains in standby mode. In one embodiment, the standby time can be obtained by acquiring the start time and real-time of the current recirculation process; where the start time is the moment the current recirculation process begins. The difference between the real-time time and the start time is then calculated.

[0055] Real-time conductivity value refers to the real-time value of the conductivity parameter detected by the conductivity monitoring unit installed in the mineralization water purification system. In practical applications, the conductivity monitoring unit can be a conductivity meter, installed inside the mineralization filter cartridge or in the pipe between the mineralization filter cartridge and the outlet of the mineralization water purification system.

[0056] It should be noted that the method for collecting real-time conductivity values ​​is not unique. In one embodiment, the real-time conductivity value can be the conductivity value during the initial period of the current reflow processing process. In another embodiment, the real-time conductivity value can also be the conductivity value during the middle or later period of the current reflow processing process. In other embodiments, the real-time conductivity value can be the conductivity value at a certain moment, or it can be the average conductivity over a certain period of time. This embodiment does not limit the specific method for calculating the real-time conductivity value.

[0057] Step 104: Calculate the mineral dissolution rate based on the real-time conductivity value.

[0058] Specifically, the mineral dissolution rate refers to the rate at which soluble components of a mineralized filter cartridge transfer from the surface or interior of the solid filter cartridge to the surrounding solution under specific conditions. It can be measured by the change in the mass or concentration of dissolved minerals per unit time. This embodiment quantifies the mineral dissolution rate using real-time conductivity, thereby accurately reflecting the mineral dissolution state of the mineralized filter cartridge at different stages of its lifespan and under different operating environments (e.g., different temperatures, different structures).

[0059] In one embodiment, because the dissolution rate of the mineralized filter element is affected by the concentration difference between the inside and outside of the filter element, the change in real-time conductivity is initially rapid, then slows down, and finally reaches an equilibrium state. When calculating the mineral dissolution rate based on the real-time conductivity value, the mineral dissolution rate for different time periods can be calculated based on different first and second dissolution rate calculation models to match the dissolution pattern of the mineralized filter element.

[0060] Step 106: Dynamically update the target duration threshold based on the mineral dissolution rate.

[0061] Specifically, the mineral dissolution rate of the mineralized filter cartridge increases steadily with its lifespan and changes continuously due to environmental parameters, such as water temperature variations. This embodiment continuously adjusts the parameters required to calculate the target duration threshold based on these changes in the mineral dissolution rate. These parameters include, for example, the limiting conductivity or saturated conductivity that the mineralized filter cartridge can release.

[0062] Specifically, the target duration threshold refers to the maximum interval between two reflux rinsing purification processes. The target duration threshold can also be understood as the duration of one reflux process. It should be noted that the target duration threshold can also be called the reflux interval duration. Each mineralized water purification system can preset an initial target duration threshold, and this threshold is dynamically updated based on changes in the mineral dissolution rate as the system is used.

[0063] It should be noted that the goal of dynamically updating the target duration threshold in this embodiment is to ensure that, while saving water resources and energy, the mineral concentration of the first cup of drinking water provided to the user when the mineralized water purification system enters the water supply mode from the standby mode remains stable within a safe mineral concentration range, thereby ensuring the quality of the output water, improving the user experience, and enhancing the safety of the product.

[0064] Step 108: If the standby time exceeds the target time threshold, control the mineral water in the mineralized filter cartridge to flow back to the reverse osmosis component of the mineralized water purification system for purification.

[0065] Specifically, when the standby time exceeds the target time threshold, the mineral water in the mineralized filter cartridge is controlled to flow back to the reverse osmosis component of the mineralized water purification system for purification, in conjunction with the reflux branch set in the mineralized water purification system. This re-purifies the high-concentration mineral water, and the high-concentration mineral water is replaced by the pure water newly prepared by the reverse osmosis component, thus rinsing the mineralized filter cartridge and preventing the mineral concentration from being too high when the user takes water next time.

[0066] The control method of the aforementioned mineralized water purification system, after the system enters standby mode, monitors the standby time and the real-time conductivity value inside or at the outlet of the mineralized filter cartridge in real time. Based on the real-time conductivity value, the mineral dissolution rate is quantified, and the backflow flushing interval is dynamically adjusted to adapt to the lifespan changes of the mineralized filter cartridge and the actual environment of the water purification system. This ensures the safety of the user's next water intake without wasting water resources and electricity. Furthermore, the flexible backflow flushing logic avoids prolonged immersion of the mineralized filter cartridge in high-concentration mineral water, effectively extending its lifespan. This solution allows for backflow purification of the mineralized water when the mineralized filter cartridge has been left to stand still for a long time due to standby or shutdown, causing the mineral concentration in the mineralized water to exceed the standard. This reduces the mineral concentration in the mineralized water, preventing excessive mineral levels and improving water safety.

[0067] In one embodiment, after step 208, the control method for the mineralized water purification system further includes:

[0068] If the mineralized water purification system is still in standby mode, the standby time will be reset to zero, and the system will return to the step of obtaining the standby time and real-time conductivity value of the current reflux process until the preset number of purification processes is completed.

[0069] Specifically, each time the mineralization water purification system enters standby mode, it can execute one or more backflow processing processes. After each backflow processing process is completed, that is, after the mineral water in the mineralization filter is controlled to flow back to the reverse osmosis component of the mineralization water purification system for purification, the standby time statistics are reset to zero so that the standby time can be accumulated again in the next backflow processing process.

[0070] Specifically, the number of times the mineralized water purification system performs the reflux process in standby mode can be limited to a preset number, such as 3 or 4 times, to avoid wasting water resources and energy.

[0071] It should be noted that if the mineralized water purification system exits standby mode during operation, such as when a user performs a water intake operation or maintenance operation, the mineralized water purification system will reset the standby time and the number of times the backflow processing process was executed in standby mode.

[0072] In one embodiment, the execution time of the reflux processing process can be adaptively adjusted according to the usage scenario of the mineralized water purification system to suit user habits. That is, multiple reflux processing processes can be executed continuously or in time intervals, without restriction.

[0073] In one embodiment, dynamically updating the target duration threshold based on the mineral dissolution rate includes:

[0074] If the mineral dissolution rate increases, decrease the target duration threshold; if the mineral dissolution rate decreases, increase the target duration threshold.

[0075] Specifically, the target duration threshold update strategy can be to shorten (reduce) the target duration threshold when the mineral dissolution rate increases. When the mineral dissolution rate increases, the real-time concentration of mineral water in the mineralization filter will increase at a faster rate, meaning the concentration of mineral water will exceed the safe concentration limit in a shorter time. In this case, shortening the target duration threshold allows the mineralization water purification system to perform backflow purification treatment more quickly, thus preventing the first cup of water from having an excessively high concentration when the user needs to take water in a short period of time.

[0076] The target duration threshold update strategy can also be to extend (increase) the target duration threshold when the mineral dissolution rate decreases. When the mineral dissolution rate decreases, the real-time concentration of mineral water within the mineralization filter cartridge will increase slowly, meaning it takes longer for the mineral water concentration to reach the safe limit. In this case, extending the target duration threshold allows the mineralization water purification system to extend the time for performing backflow purification, thus avoiding the system consuming more water and electricity.

[0077] In one embodiment, the formula for calculating the target duration threshold can be:

[0078]

[0079] in, The target duration threshold, For real-time dissolution rate, This refers to the permissible limit of conductivity (safety value) for the target filter element. This is the limiting conductivity (saturation value) that the filter element can release.

[0080] Based on the above scheme, by proposing a specific calculation model for the reflux rinsing interval, i.e., the target duration threshold, it can be ensured that the target duration threshold can be dynamically updated according to the real-time dissolution rate, and can be achieved through specific... The lifespan conditions of the mineralized filter cartridge and real-time environmental parameters are taken into account to make the target duration threshold correlate with various influencing factors in the static state of the mineralized water purifier, thereby enabling more precise and flexible control of the mineralized water purification system for backflow flushing.

[0081] Please see Figure 2 In one embodiment, step 104 includes steps 202 and 204.

[0082] Step 202: When the standby time is less than or equal to the preset time threshold, calculate the first mineral dissolution rate based on the first dissolution rate calculation model, the initial conductivity value, and the real-time conductivity value; the preset time threshold is less than the target time threshold.

[0083] Step 204: If the standby time exceeds the preset time threshold, calculate the second mineral dissolution rate based on the second dissolution rate calculation model, the standby time, the limiting conductivity saturation value of the mineralized filter element, and the dissolution rate constant.

[0084] Specifically, the preset time threshold is used to distinguish between the initial and later stages of water immersion in the mineralization filter element during standby mode. A standby time less than or equal to the preset time threshold indicates that the pure water produced by the reverse osmosis module is in the initial stage of immersion in the mineralization filter element after entering it. A standby time greater than the preset time threshold indicates that the pure water produced by the reverse osmosis module is in the later stage of immersion in the mineralization filter element after entering it.

[0085] The calculation formula for the first dissolution rate calculation model is as follows:

[0086]

[0087] in, This refers to the first mineral dissolution rate, which can also be understood as the mineral dissolution rate during the initial soaking of the mineralized filter cartridge. The standby time is the first Real-time conductivity value per minute (min). This is the initial conductivity value. This refers to the standby time.

[0088] It should be noted that the preset time threshold can be set according to the actual material characteristics of the mineralized filter element in the actual application scenario, for example, set to 0-60 minutes, i.e. Within the specified range, the dissolution rate of the first mineral is calculated according to the above first dissolution rate calculation model.

[0089] The calculation formula for the second dissolution rate calculation model is as follows:

[0090]

[0091] in, This refers to the second mineral dissolution rate, which can also be understood as the mineral dissolution rate during the later stages of soaking the mineralized filter cartridge. This is the dissolution rate constant, which can be determined based on the actual material properties of the mineralized filter element. This refers to the standby time. This is the limiting conductivity saturation value of the mineralized filter element, that is, the limiting conductivity (saturation value) that the element can release.

[0092] In one embodiment, due to the continuous use of the mineralized filter cartridge and changes in the environment (such as water temperature), It will adaptively change with the lifespan of the mineralized filter element and environmental parameters. In this embodiment, Will follow It changes constantly with the changes. The specific ways in which it changes are shown in Table 1 below:

[0093] Table 1

[0094]

[0095] in, , .

[0096] Based on the above scheme and It will continuously change with the standby time, so the mineralized water purification system not only adapts to the changing needs of the environment and filter life, but also directly calculates the dissolution rate through conductivity, saving the cost of parts such as flow meters and temperature sensors, making it more economical.

[0097] Please see Figure 3 In one embodiment, the control method for the mineralized water purification system further includes:

[0098] Step 301: Collect user water collection behavior data, which includes the duration of each water collection, the amount of water collected, and the purpose of the water collection.

[0099] Step 302: Perform cluster analysis on the water intake behavior data to identify high-frequency water intake periods and low-frequency water intake periods.

[0100] Step 303: Construct a water intake behavior model based on high-frequency water intake periods and low-frequency water intake periods.

[0101] Step 304: Determine whether to perform a backflow flushing operation based on the current real-time time and water intake behavior model.

[0102] Step 305: If it is determined that a backflow flushing operation will be performed and the standby time is greater than the target time threshold, the mineral water in the mineralized filter element is controlled to flow back to the reverse osmosis component of the mineralized water purification system for purification treatment.

[0103] Specifically, since the activation time of the pure water reflux may overlap with the user's water-taking action, if the user takes water during the rinsing process, it may result in contamination of the first cup of water or disturbance to the user due to noise. This embodiment adds steps 301-305 to the mineralized water purification system to collect and analyze user water-taking habits, which can effectively improve the user experience.

[0104] Specifically, user water-taking behavior data can be collected and processed through multiple devices. For example, the start time of each water-taking session can be recorded on the device itself. End time Duration Water intake The system obtains user-defined water usage information via the app, such as drinking, cooking, and washing vegetables. Events such as device power on / off, app operations, and remote control are recorded via network logs. It should be noted that user water usage data can be customized to meet the needs of specific application scenarios, and the actual data collection method can also be adjusted accordingly.

[0105] In one embodiment, the time period for collecting user water-taking behavior data should be greater than or equal to a preset data storage period, such as greater than or equal to 14 days, to ensure that user water-taking behavior patterns can be learned.

[0106] Cluster analysis of user behavior can identify water consumption characteristics, such as multiple high-frequency and low-frequency water consumption periods. High-frequency water consumption periods include 7:00–8:30 (morning), 12:00–13:30 (noon), and 18:00–20:00 (evening). Low-frequency water consumption periods include 23:00–6:00 (night).

[0107] By combining the aforementioned high-frequency and low-frequency water withdrawal periods, a water withdrawal behavior model can be constructed for specific scenarios. It should be noted that the water withdrawal behavior model not only includes all high-frequency and low-frequency water withdrawal periods, but also records the corresponding scenario-based water withdrawal cycles, such as no water withdrawal on weekend mornings and concentrated water withdrawal at midday on weekdays.

[0108] In practical applications, after obtaining the current real-time time, the system compares the current real-time time with the time period and scenario recorded in the water intake behavior model to determine whether the current real-time time belongs to a peak water intake period, such as a high-frequency water intake period, and / or whether the scenario belongs to a concentrated water intake scenario. If both are negative, the system determines that a backflow flushing operation can be performed, and steps 102-108 are then executed. If any condition is positive, the backflow flushing operation can be temporarily suspended.

[0109] In one embodiment, it can also be determined whether to perform a backflow flushing operation in advance based on the current real-time time and the peak time of user water consumption.

[0110] If the current real-time time is determined to be during peak water consumption hours, a backflow flushing operation can be performed in advance. For example, if a user typically takes water at 8:00 AM, the system can automatically complete the backflow purification process at 7:00 AM, ensuring safe and undisturbed water quality when the user takes water at 8:00 AM.

[0111] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0112] Based on the same inventive concept, this application also provides a control device for a mineralized water purification system to implement the control method of the mineralized water purification system described above. The solution provided by this device is similar to the solution described in the above method. Therefore, the specific limitations in one or more embodiments of the control device for a mineralized water purification system provided below can be found in the limitations of the control method for the mineralized water purification system described above, and will not be repeated here.

[0113] In one embodiment, such as Figure 4 As shown, a control device 400 for a mineralized water purification system is provided, comprising: an acquisition module 410, a calculation module 420, an update module 430, and an execution module 440, wherein:

[0114] The acquisition module 410 is used to acquire the standby time and real-time conductivity value of the current reflux processing process if the mineralized water purification system is in standby mode.

[0115] The calculation module 420 is used to calculate the mineral dissolution rate based on the real-time conductivity value.

[0116] Update module 430 is used to dynamically update the target duration threshold based on the mineral dissolution rate.

[0117] The execution module 440 is used to control the mineral water in the mineralized filter cartridge to flow back to the reverse osmosis component of the mineralized water purification system for purification when the standby time exceeds the target time threshold.

[0118] In one embodiment, the update module 430 is further configured to decrease the target duration threshold if the mineral dissolution rate increases, and increase the target duration threshold if the mineral dissolution rate decreases.

[0119] In one embodiment, the calculation module 420 is further configured to calculate the first mineral dissolution rate based on the first dissolution rate calculation model, the initial conductivity value, and the real-time conductivity value when the standby time is less than or equal to a preset time threshold; the preset time threshold is less than the target time threshold.

[0120] When the standby time exceeds the preset time threshold, the second mineral dissolution rate is calculated based on the second dissolution rate calculation model, the standby time, the limiting conductivity saturation value of the mineralized filter element, and the dissolution rate constant.

[0121] In one embodiment, the execution module 440 is further configured to collect user water-taking behavior data, which includes the duration of each water-taking session, the amount of water taken, and a water-taking purpose marker; perform cluster analysis on the water-taking behavior data to identify high-frequency water-taking periods and low-frequency water-taking periods; construct a water-taking behavior model based on the high-frequency water-taking periods and the low-frequency water-taking periods; determine whether to perform a backflow flushing operation based on the current real-time time and the water-taking behavior model; and, if it is determined that a backflow flushing operation should be performed, and the standby time is greater than the target time threshold, control the mineral water in the mineralized filter cartridge to flow back to the reverse osmosis component of the mineralized water purification system for purification treatment.

[0122] In summary, this embodiment provides a control device for a mineralized water purification system. After the system enters standby mode, it monitors the standby time and the real-time conductivity value inside or at the outlet of the mineralized filter cartridge. Based on the real-time conductivity value, it quantifies the mineral dissolution rate and dynamically adjusts the backflow flushing interval to adapt to changes in the lifespan of the mineralized filter cartridge and the actual environment of the purification system. This ensures the safety of the user's next water intake without wasting water resources or electricity. Furthermore, the flexible backflow flushing logic prevents the mineralized filter cartridge from being soaked in high-concentration mineral water for extended periods, effectively extending its lifespan. This solution allows for backflow purification of the mineralized water when the mineralized filter cartridge's mineral concentration exceeds the standard due to prolonged immersion during standby or shutdown, thereby reducing the mineral concentration and improving water safety.

[0123] Each module in the control device of the aforementioned mineralized water purification system can be implemented entirely or partially through software, hardware, or a combination thereof. These modules can be embedded in the processor of a computer device in hardware form or independent of it, or stored in the memory of a computer device in software form, so that the processor can call and execute the operations corresponding to each module.

[0124] Please see Figure 5This application also provides a mineralized water purification system, including: an inlet 510, an outlet 520, a pure water branch 530, a return branch 540, and a control component (not shown in the figure).

[0125] The pure water branch 530 includes a power assembly 531, a reverse osmosis assembly 532, a mineralization filter element 533, and a conductivity monitoring unit 534 connected in sequence. One end of the power assembly 531 is connected to the inlet 510, and the outlet end of the mineralization filter element 533 is connected to the outlet 520. The conductivity monitoring unit 534 is located inside the mineralization filter element 533 or between the outlet end of the mineralization filter element 533 and the outlet 520. The conductivity monitoring unit 534 is used to detect the conductivity value of the water. The power assembly 531 can be a pressure-stabilizing pump or other types of pump. The power assembly 531 provides driving force for the water in the pipeline. The reverse osmosis assembly 532 is used to purify the water.

[0126] The return branch 540 includes a return solenoid valve 541 and a check valve 542. One end of the return solenoid valve 541 is connected to the outlet, and the other end is connected to the power assembly 531 via the check valve 542. The return solenoid valve 541 controls the opening and closing of the return branch 540. The check valve 542 prevents water in the inlet of the pure water branch 530 from flowing back into the return branch 540.

[0127] The control components are connected to the power component 531, the conductivity monitoring unit 534, and the return solenoid valve 541, respectively.

[0128] The control component is used to execute the control method of the mineralized water purification system in the foregoing embodiments. The specific functions of the control component will not be described in detail here.

[0129] In one embodiment, the mineralized water purification system further includes: a wastewater outlet 560 and a wastewater branch 550;

[0130] Wastewater branch 550 includes a wastewater solenoid valve 551; one side of the wastewater solenoid valve 551 is connected to the reverse osmosis module 532, and the other side is connected to the wastewater outlet 560; the wastewater solenoid valve 551 is connected to a control component. The wastewater solenoid valve 551 is used to control the on / off state of the wastewater branch 550. The wastewater outlet 560 and the wastewater branch 550 are used in conjunction with the reverse osmosis module 532 to discharge filtered wastewater.

[0131] In one embodiment, the pure water branch also includes a pretreatment filter assembly (not shown in the figure); the pretreatment filter assembly is disposed between the water inlet and the power unit.

[0132] Specifically, the pretreatment filter cartridge assembly includes filter materials such as activated carbon filter cartridges, PP filter cartridges, or ultrafiltration filter cartridges. It should be noted that the pretreatment filter cartridge assembly is used to pretreat water quality, and the actual material type of the pretreatment filter cartridge can be determined according to the needs of the actual application scenario.

[0133] In summary, this embodiment provides a mineralized water purification system. After the system enters standby mode, it monitors the standby time and the real-time conductivity value inside or at the outlet of the mineralized filter cartridge. Based on the real-time conductivity value, it quantifies the mineral dissolution rate and dynamically adjusts the backflow flushing interval to adapt to changes in the lifespan of the mineralized filter cartridge and the actual environment of the purification system. This ensures the safety of the user's next water intake without wasting water resources and electricity. Furthermore, the flexible backflow flushing logic prevents the mineralized filter cartridge from being soaked in high-concentration mineral water for extended periods, effectively extending its lifespan. This solution allows for backflow purification of the mineralized water when the mineralized filter cartridge's mineral concentration exceeds the standard due to prolonged immersion during standby or shutdown, thereby reducing the mineral concentration and improving water safety.

[0134] This application also provides a mineralization water purification device, including the above-mentioned mineralization water purification system.

[0135] Specifically, the structure and implementation of the mineralized water purification system are as shown in the above embodiments and accompanying drawings, and will not be repeated here.

[0136] The aforementioned mineralization water purification equipment, after the mineralization water purification system enters standby mode, monitors the standby time and the real-time conductivity value inside or at the outlet of the mineralization filter element in real time. Based on the real-time conductivity value, it quantifies the mineral dissolution rate and dynamically adjusts the backflow flushing interval to adapt to the lifespan changes of the mineralization filter element and the actual environment of the water purification system. This ensures the safety of the user's next water intake without wasting water resources and electricity. Furthermore, the flexible backflow flushing logic avoids prolonged immersion of the mineralization filter element in high-concentration mineral water, effectively extending its lifespan. This solution allows for backflow purification of the mineralized water when the mineralization filter element has been left to stand still for a long time due to standby or shutdown, causing the mineral concentration in the mineralized water to exceed the standard. This reduces the mineral concentration in the mineralized water, preventing excessive mineral levels and improving water safety.
