Description

Technical Field

[0001] This application relates to the field of water treatment equipment technology, specifically to a water circuit system for a mineral water purifier and a mineral water purifier. Background Technology

[0002] With increased productivity, people's demands for quality of life and convenience are also rising. Alkaline water, with a pH value greater than 7, can replenish fluids, improve microcirculation, and promote metabolism when consumed in moderation. Furthermore, alkaline water can help alleviate water and electrolyte imbalances; for example, it can aid in rehydration after significant vomiting. In addition, alkaline water can help neutralize excess stomach acid, protect the gastric mucosa, and reduce the likelihood of peptic ulcers. Therefore, mineralized water is widely favored as drinking water. There is also a certain demand for alkaline water during production and experimental processes.

[0003] Currently, there are two common methods for preparing alkaline water. The first is to artificially mix alkaline substances with water to create alkaline water with a suitable pH value. However, this method is cumbersome, requires a certain level of chemical knowledge, and is relatively inefficient. The second method involves adding alkaline filter media to a container filled with water—such as a water dispenser or water purifier. The alkaline substances in the filter media dissolve into the water, turning it into alkaline water. In the early stages of use, a large amount of alkaline substances enters the water, causing the pH value of the alkaline water to be too high during this period. In the later stages of use, the alkaline substance content in the filter media decreases, resulting in less alkaline substances entering the water, and the pH value of the alkaline water becomes too low during this period. Alkaline water with excessively high or low pH values ​​cannot meet water requirements and significantly affects the usability of the alkaline filter media. Utility Model Content

[0012] In one specific embodiment, the water circuit system for the mineral water purifier further includes a second water quality detection device and a water purification component. The output end of the water purification component is connected to the end of the rear water inlet circuit away from the first diversion valve. The second water quality detection device is disposed in the rear water inlet circuit and is connected to the controller. The first water quality detection device and the second water quality detection device each include at least one of a TDS value detection device and a pH value detection device.

[0013] In one specific embodiment, the water circuit system for the mineral water purifier further includes a first return water circuit, which is connected to the water purification component; the water circuit system for the mineral water purifier also includes a third diverter valve, which connects the purified water circuit and the end of the first return water circuit away from the water purification component; and / or, the water circuit system for the mineral water purifier further includes a fourth diverter valve, which is connected to the rear-entry water circuit and located behind the second water quality detection element in the preset water flow direction, and the fourth diverter valve is also connected to the end of the first return water circuit away from the water purification component.

[0016] Furthermore, when the first alkaline filter material and the second alkaline filter material are installed in the same filter material mounting cavity, during the service life of the water circuit system used in the mineral water purifier, the first alkaline filter material, which is more alkaline, can suppress the second alkaline filter material, which is less alkaline, in the early stage of use. The strong alkaline filter material releases alkaline substances in the early stage and releases alkaline substances together with the weak alkaline filter material in the middle and later stages. The two can work together to greatly improve the life of the filter element in the alkaline water circuit, thereby achieving a longer filter element life. Attached Figure Description

[0030] 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.

[0031] With increased productivity, people's demands for quality of life and convenience are also rising. Alkaline water, with a pH value greater than 7, can replenish fluids, improve microcirculation, and promote metabolism when consumed in moderation. Furthermore, alkaline water can help alleviate water and electrolyte imbalances; for example, it can aid in rehydration after significant vomiting. In addition, alkaline water can help neutralize excess stomach acid, protect the gastric mucosa, and reduce the likelihood of peptic ulcers. Therefore, mineralized water is widely favored as drinking water. There is also a certain demand for alkaline water during production and experimental processes.

[0032] Currently, there are two common methods for preparing alkaline water. The first is to artificially mix alkaline substances with water to create alkaline water with a suitable pH value. However, this method is cumbersome, requires a certain level of chemical knowledge, and is relatively inefficient. The second method involves adding alkaline filter media to a container filled with water—such as a water dispenser or water purifier. The alkaline substances in the filter media dissolve into the water, turning it into alkaline water. In the early stages of use, a large amount of alkaline substances enters the water, causing the pH value of the alkaline water to be too high during this period. In the later stages of use, the alkaline substance content in the filter media decreases, resulting in less alkaline substances entering the water, and the pH value of the alkaline water becomes too low during this period. Alkaline water with excessively high or low pH values ​​cannot meet water requirements and significantly affects the usability of the alkaline filter media.

[0033] In order to improve or solve the above technical problems, the inventors of this application, after long-term research, have proposed at least the following embodiments.

[0034] See Figure 3 , Figure 4 , Figure 3 This is a schematic diagram of the water circuit structure of an embodiment of the water circuit system for a mineral water purifier provided in this application. Figure 4 This is a schematic diagram of the water circuit structure of another embodiment of the water circuit system for a mineral water purifier provided in this application. Specific embodiments of this application provide a water circuit system for a mineral water purifier, used to treat fluids to output alkaline water.

[0035] The water system for a mineral water purifier may include a first alkaline filter material 1, a second alkaline filter material 2, and an alkaline water path 43. The alkalinity of the first alkaline filter material 1 is greater than that of the second alkaline filter material 2. The first alkaline filter material 1 can be used to inhibit the release of alkaline substances from the second alkaline filter material 2.

[0036] In the alkaline water path 43, the first alkaline filter material 1 and the second alkaline filter material 2 can be arranged sequentially along a preset water flow direction. Alternatively, the alkaline water path 43 can be provided with a filter material mounting cavity 3 for simultaneously accommodating the first alkaline filter material 1 and the second alkaline filter material 2.

[0037] In the structure provided in this specific embodiment, by simultaneously setting the first alkaline filter material 1 and the second alkaline filter material 2 in the alkaline water path 43, the first alkaline water flowing through the first alkaline filter material 1 and the second alkaline water flowing through the second alkaline filter material 2 can be mixed. Thus, by using the first alkaline water and the second alkaline water with different alkalinity, alkaline water with moderate alkalinity that meets the usage requirements can be prepared for use. This can reduce the probability that the pH value of the final output water of the water path system used in the mineral water purifier is too high, and can improve the safety and stability of the water path system used in the mineral water purifier.

[0038] Furthermore, when the first alkaline filter material 1 and the second alkaline filter material 2 are installed in the same filter material mounting cavity 3, during the service life of the water circuit system used in the mineral water purifier, the first alkaline filter material 1, which is more alkaline, can suppress the second alkaline filter material 2, which is less alkaline, in the early stage of use. The strong alkaline filter material releases alkaline substances in the early stage and releases alkaline substances together with the weak alkaline filter material in the middle and later stages. The two can work together to greatly improve the life of the filter element in the alkaline water circuit 43, thereby achieving a longer filter element life.

[0039] In practical applications, the second alkaline filter material 2 can be a weakly alkaline filter material, and the first alkaline filter material 1 can be a strongly alkaline filter material. The relative alkalinity between the weakly and strongly alkaline filter materials is a relative concept; that is, the alkalinity of the first alkaline filter material 1 is higher than that of the second alkaline filter material 2. The alkaline substances released by the first alkaline filter material 1 and the second alkaline filter material 2 may include hydroxide ions (OH-). - and bicarbonate ions HCO3 - .

[0040] Strongly alkaline filter media can be made from strongly alkaline materials, such as at least one of brucite, periclase, sepiolite, and magnesite. Taking brucite as an example, brucite contains Mg(OH)₂, allowing it to undergo reaction A in water, thereby releasing (dissolving) OH⁻. - This can enhance the alkalinity of the water, raising its pH value and resulting in alkaline water.

[0041] Reaction A: Mg(OH)₂ = Mg 2+ +2OH -

[0042] Weakly alkaline filter media can be made from at least one of the following materials: calcite, dolomite, stalactite, limestone, and Iceland spar. Taking calcite as an example, calcite contains CaCO3. When calcite is immersed in water, reaction B first occurs, releasing CO3 into the water. 2- Then CO3 2- It can undergo a hydrolysis reaction with H2O to produce OH. - .

[0043] Reaction B: CaCO3 = Ca 2+ +CO3 2-

[0044] Reaction C: CO3 2- +H2O HCO3 - +OH -

[0045] This reveals that strongly alkaline filter media only requires one reaction step to produce OH. - Weakly alkaline filter media requires two steps of reaction to obtain OH-. - Furthermore, the rate of reaction C is much lower than the rate of reaction A, therefore, strongly alkaline materials will preferentially dissolve OH- into the water. - Furthermore, reaction C is a reversible reaction. When reaction A occurs preferentially, the chemical equilibrium of reaction C shifts to the left. Therefore, strongly alkaline filter media can suppress the OH- of weakly alkaline filter media. - release.

[0046] like Figure 3 As shown, strong alkaline filter media and weak alkaline filter media are combined to form a parallel structure, and the fluid in alkaline water path 43 flows through both strong alkaline and weak alkaline filter media simultaneously. Furthermore, the strong alkaline and weak alkaline filter media can be installed in two separate filter cartridges, or they can be assembled in the same filter cartridge. When the strong alkaline and weak alkaline filter media are located in the same filter cartridge, the inhibitory effect of the strong alkaline filter media on the weak alkaline filter media can be utilized. During the entire service life of the filter cartridge, the strong alkaline filter media releases OH- in the early stages. - In the later stages, it releases OH- along with the weakly alkaline filter material.- The two can work together to greatly improve the lifespan of the filter element in alkaline water path 43, thereby extending the lifespan of the filter element.

[0047] like Figure 4 As shown, the strongly alkaline filter media and the weakly alkaline filter media are combined to form an axially integrated structure. The fluid in the alkaline water path 43 first flows through the strongly alkaline filter media and then through the weakly alkaline filter media. Furthermore, the strongly alkaline and weakly alkaline filter media can be respectively installed in two filter elements, or they can be assembled in the same filter element. When the strongly alkaline and weakly alkaline filter media are located in the same filter element, the inhibitory effect of the strongly alkaline filter media on the weakly alkaline filter media can be utilized. During the entire service life of the filter element, the strongly alkaline filter media releases OH- in the early stage. - In the later stages, it releases OH- along with the weakly alkaline filter material. - The two can work together to greatly improve the lifespan of the filter element in alkaline water path 43, thereby extending the lifespan of the filter element.

[0048] See Figure 1 , Figure 2 , Figure 1 This is a graph showing the pH trend of the flowing water through the first and second alkaline filter media individually. (See attached graph.) Figure 2 , Figure 2 The chart shows the pH trend of water flowing through the first alkaline filter media alone, the second alkaline filter media alone, and the mixed flow. Several examples were obtained by adjusting the mass ratio of strongly alkaline and weakly alkaline filter media. The pH values ​​of the flowing water were tested for different flow rates in each example, as shown in Table 1. The adjustment range of the mass ratio of the strongly alkaline filter media was 10%–50%, and the corresponding adjustment range of the mass ratio of the weakly alkaline filter media was 50%–90%.

[0049] Table 1

[0050]

[0051] Based on Table 1 and... Figure 1 , Figure 2 Analysis revealed that when the proportion of strongly alkaline filter media was 0%, meaning only weakly alkaline filter media was present, the slow dissolution rate and poor alkalization ability of the weakly alkaline filter media resulted in an outlet water pH value below 7 during the first 2000L of water flow. Therefore, the desired alkaline water could not be obtained initially. Subsequently, as the flow rate increased, the pores within the weakly alkaline material gradually became interconnected under the impact of the water flow. Water could pass not only through the surface of the material but also through its interior, increasing the contact area between water molecules and the mineralizing material, thus increasing the reaction rate and causing the pH value of the flowing water to gradually rise to above 7.

[0052] When the proportion of strongly alkaline filter media increased to 5%, the pH value at 0L increased. This is because the addition of 5% strongly alkaline filter media initially releases OH- into the flowing water. - When the proportion of strongly alkaline filter media is between 10-50%, the pH value can be maintained between 7.0-9.0 throughout the entire lifespan, thus obtaining alkaline water that meets the water usage requirements.

[0053] When the proportion of strongly alkaline filter media reaches 60%, the initial pH reaches 9.15, exceeding the range of weakly alkaline water and not meeting the water usage requirements. When the proportion of strongly alkaline filter media reaches 100%, the initial pH reaches 10.12, far exceeding the upper limit of 9, and the pH decays rapidly. When the flow rate reaches 6000L, the pH is already below 7. This is because the strongly alkaline material releases OH- into the flowing water. - Strong ability, but due to OH - If the dissolution is too rapid, the alkaline substances contained in the strongly alkaline filter material will be consumed quickly, which will weaken the filter element's ability to produce alkaline water in the later stages of use.

[0054] It should be noted that, Figure 1 , Figure 2 The flow can involve different combinations of the first alkaline filter media 1 and the second alkaline filter media 2, or it can involve different flow rates and / or velocities of the flowing water. The alkalinity of the alkaline substances dissolved into the water by different first alkaline filter media 1 is not necessarily the same. Similarly, the alkalinity of the alkaline substances dissolved into the water by different second alkaline filter media 2 is not necessarily the same. Furthermore, the amount of alkaline substances contained in the flowing water with different flow rates and / or velocities is not necessarily the same.

[0055] Due to various reasons, Figure 1 The curve representing strongly alkaline wastewater shows the pH value over its service life, and... Figure 2 The pH values ​​of the curve representing strongly alkaline mineral water differ throughout its lifespan, but it is not difficult to see that... Figure 1 and Figure 2 The curves in the two samples show similar trends, and the same applies to weakly alkaline flowing water and weakly alkaline mineral water.

[0056] Therefore, although the specific values ​​are different, the combination of the first alkaline filter material 1 and the second alkaline filter material 2 can have a similar impact on the pH value of the alkaline water output by the water system.

[0057] Optionally, such as Figure 3 , Figure 4As shown, the water system may further include a second return water path 45, a second drainage branch 46, a pre-inlet water path 47, a return valve 52, an inlet valve 53, a wastewater valve 54, and a pump body 8. The second return water path 45 is connected at one end to the inlet water path and at the other end to the input end of the water purification component 7. The return valve 52 is connected to the second return water path 45. The pre-inlet water path 47 connects to an external water source and the input end of the water purification component 7. The pump body 8 and the inlet valve 53 are connected to the pre-inlet water path 47, allowing the water in the entire water system to flow under the drive of the pump body 8. The second drainage branch 46 connects to the wastewater outlet of the water purification component 7, used to discharge the wastewater generated during the water purification process of the water purification component 7 to the outside. The wastewater valve 54 is connected to the drainage branch.

[0058] In one specific embodiment provided in this application, the water system may include a post-inlet water channel 41, a purified water channel 42, and an outlet water channel 44. The post-inlet water channel 41 is connected to the purified water channel 42 and the alkaline water channel 43. The ends of the purified water channel 42 and the alkaline water channel 43 furthest from the post-inlet water channel 41 are both connected to the outlet water channel 44.

[0059] In the structure provided in this specific embodiment, the purified water output from the pure water circuit 42 and the alkaline water output from the alkaline water circuit 43 can be mixed and then output through the water outlet circuit 44, thereby further adjusting the alkaline water. This can reduce the probability that the pH value of the final water output from the water circuit system of the mineral water purifier is too high, and improve the safety and stability of the water circuit system of the mineral water purifier.

[0060] In one specific embodiment provided in this application, the water system may further include a first diversion valve 51, which is connected to and placed into a water path 41, a pure water path 42, and an alkaline water path 43.

[0061] In the structure provided in this specific embodiment, the first diversion valve 51 can control the amount of water input into the pure water channel 42 and the alkaline water channel 43 through the rear water channel 41, thereby controlling the ratio of alkaline water to purified water when water is discharged from the outlet channel 44. This further adjusts the alkaline water, reducing the probability of the final output water of the water system used in the mineral water purifier having an excessively high pH value, and improving the safety and stability of the water system used in the mineral water purifier.

[0062] In one specific embodiment provided in this application, the water system further includes a first flow valve and a second flow valve, wherein the first flow valve is connected to the pure water circuit 42 and the second flow valve is connected to the alkaline water circuit 43.

[0063] The structure provided in this specific embodiment can control the opening and closing of the first flow valve and the second flow valve, thereby controlling the flow rate and velocity of alkaline water flowing out through the alkaline water path 43 and purified water flowing out through the pure water path 42. This allows for control of the ratio of alkaline water to purified water flowing into and out of the water path 44, enabling further adjustment of the alkaline water and improving the safety and stability of the water system used in the mineral water purifier.

[0064] In one specific embodiment provided in this application, the water circuit system for the mineral water purifier further includes a first water quality detection element 61 and a controller. The first water quality detection element 61 and the first diversion valve 51 are both connected to the controller. The first water quality detection element 61 is disposed in the alkaline water circuit 43 and is located behind the first alkaline filter material 1 and the second alkaline filter material 2 in a preset water flow direction.

[0065] Optionally, the first water quality testing device 61 can also be installed in the water outlet 44.

[0066] In the structure provided in this specific embodiment, the first water quality detection element 61 is set in the water outlet 44 to directly characterize the final water quality when the water is discharged. The first water quality detection element 61 is set in the alkaline water outlet 43 to measure the water quality of alkaline water. Based on the water quality of alkaline water, the ratio of alkaline water to purified water required to adjust to a specified pH range can be calculated.

[0067] Therefore, by setting the first water quality detection device 61, the water quality of the water body in the water system can be effectively monitored. This allows the controller to adjust at least one of the valves, such as the first diversion valve 51, the first flow valve, and the second flow valve, based on the water quality feedback. This improves the accuracy of the water system in regulating the alkalinity of the output water, enabling the water system to output water that better meets the user's needs and enhancing the availability of the water system.

[0068] In one specific embodiment provided in this application, the water system for a mineral water purifier may further include a first flow detection element 62. The first flow detection element 62 is disposed in at least one of the downstream water channel 41, the alkaline water channel 43, and the purified water channel 42, and is connected to a controller. The first flow detection element 62 can monitor the amount of water flowing through the alkaline water channel 43 and even the entire water system, thereby monitoring the service life of the water system. In conjunction with the first water quality detection element 61, it can effectively monitor the working effect of the water system at different stages of use, thereby improving the availability of the water system.

[0069] In one specific embodiment provided in this application, the first water quality detection element 61 is disposed in the alkaline water path 43 and is located behind the first alkaline filter material 1 and the second alkaline filter material 2 in a preset water flow direction. The water system for the mineral water purifier also includes a second diversion valve, which is connected to a controller and is located in the alkaline water path 43, behind the first water quality detection element 61 in the preset water flow direction. The water system for the mineral water purifier also includes a first drainage branch and a wastewater outlet, with one end of the first drainage branch connected to the second diversion valve and the other end connected to the wastewater outlet.

[0070] In the structure provided in this specific embodiment, the first drainage branch can be used in conjunction with the second diversion valve to input the portion of alkaline water in the alkaline water path 43 that meets the usage requirements into the water outlet path 44, and to discharge the portion of water that does not meet the usage requirements to the outside, thereby reducing problems such as excessive water output, pH value exceeding the standard, and pH value being too low in the water outlet path 44, and improving the availability of the water system.

[0071] In one specific embodiment provided in this application, the water system for the mineral water purifier may further include a second water quality detection element 63 and a water purification component 7. The output end of the water purification component 7 is connected to the end of the rear water inlet 41 away from the first diversion valve 51. The second water quality detection element 63 is disposed in the rear water inlet 41 and is connected to a controller. Both the first water quality detection element 61 and the second water quality detection element 63 include at least one of a TDS value detector and a pH value detector.

[0072] In the structure provided in this specific embodiment, the second water quality detection device 63 can detect the water quality in the water circuit 41 after the water purification component 7 is input, thereby monitoring the water quality before the water is input into the alkaline water circuit 43, realizing the prediction and calculation of the pH value of the water outlet 44, and improving the availability of the water circuit system.

[0073] Among them, the pH sensor is used to detect the concentration of hydrogen ions in the analyte and convert it into a corresponding usable output signal, thereby characterizing the pH value of the water body. The TDS sensor is a device used to measure the total dissolved solids (TDS) in water. It can continuously monitor the conductivity value of the analyte, and the pH value of the analyte can be calculated based on the conductivity value, thus characterizing the pH value of the water body.

[0074] In one specific embodiment provided in this application, the water system for the mineral water purifier may further include a first return water path, which is connected to the water purification component 7. The water system for the mineral water purifier also includes a third diversion valve, which is connected to the pure water path 42 and the end of the first return water path away from the water purification component 7.

[0075] Optionally, the water system for the mineral water purifier may also include a fourth diversion valve, which is connected to the rear water inlet 41 and located behind the second water quality detection element 63 in a preset water flow direction. The fourth diversion valve is also connected to the end of the first return water inlet away from the water purification component 7.

[0076] In the structure provided in this specific embodiment, the first return water path can be used to return water in the pure water path 42 to the water purification component 7, thereby reducing the probability of excessive purified water causing the pH value of the outlet water to be too low and avoiding waste of purified water. At the same time, the first return water path can also return purified water that does not meet the usage standards to the water purification component 7 for further filtration, thereby reducing the probability of the water quality in the outlet water path 44 being substandard.

[0077] In one specific embodiment provided in this application, the water system for the mineral water purifier may further include a communication component connected to a controller. The communication component can be used to receive water quality control messages, and the controller can control the water system according to the water quality control messages, thereby outputting water that conforms to the water quality control messages through the water outlet 44.

[0078] This application also provides a mineral water purifier, including a water outlet component and a water circuit system for the mineral water purifier as described in any of the above embodiments. The water outlet component is used to dissipate water to the outside environment and is connected to the water outlet path 44 of the water circuit system for the mineral water purifier.

[0079] In the structure provided in this specific embodiment, by simultaneously setting the first alkaline filter material 1 and the second alkaline filter material 2 in the alkaline water path 43, the first alkaline water flowing through the first alkaline filter material 1 and the second alkaline water flowing through the second alkaline filter material 2 can be mixed. Thus, by using the first alkaline water and the second alkaline water with different alkalinity, alkaline water with moderate alkalinity that meets the usage requirements can be prepared for use. This can reduce the probability that the pH value of the final output water of the water path system used in the mineral water purifier is too high, and can improve the safety and stability of the water path system used in the mineral water purifier.

[0080] Furthermore, when the first alkaline filter material 1 and the second alkaline filter material 2 are installed in the same filter material mounting cavity 3, during the service life of the water circuit system used in the mineral water purifier, the first alkaline filter material 1, which is more alkaline, can suppress the second alkaline filter material 2, which is less alkaline, in the early stage of use. The strong alkaline filter material releases alkaline substances in the early stage and releases alkaline substances together with the weak alkaline filter material in the middle and later stages. The two can work together to greatly improve the life of the filter element in the alkaline water circuit 43, thereby achieving a longer filter element life.

[0081] This application also provides a control method for a mineral water purifier, see below. Figure 5 , Figure 5This is a flowchart illustrating an embodiment of a control method for a mineral water purifier. It should be noted that if substantially the same result is achieved, this embodiment is not necessarily identical. Figure 5 The illustrated process sequence is limited. For example... Figure 5 As shown, the control method for this mineral water purifier may include:

[0082] S100: Receive water quality control messages.

[0083] S200: In response to a water quality control message, control the first diversion valve 51 to adjust the flow ratio of the input alkaline water path 43 and the pure water path 42.

[0084] The execution subject of the control method for the mineral water purifier provided in this application can be a controller for the water circuit system of the mineral water purifier. The controller is connected to the first diversion valve 51 and can receive water quality control messages, thereby controlling the water quality of the water body output from the outlet water circuit 44 by adjusting the flow ratio of the input alkaline water circuit 43 and the pure water circuit 42.

[0085] The water quality control message can be generated locally on the mineral water purifier device, for example, by the user inputting a command into the mineral water purifier through a keypad operation to generate the corresponding water quality control message. Alternatively, it can be generated on the client side, where the client and the mineral water purifier are connected via a communication component. The communication component receives the water quality control message generated and sent by the client and transmits it to the controller.

[0086] See Figure 6 , Figure 6 This is a flowchart illustrating another embodiment of the control method for a mineral water purifier. It should be noted that if substantially the same result is achieved, this embodiment is not necessarily identical. Figure 6 The illustrated process sequence is limited. For example... Figure 6 As shown, the control method for this mineral water purifier may also include:

[0087] S300: Obtain the total flow parameter from the first flow detection element 62, and determine whether the total flow parameter is greater than or equal to the first threshold.

[0088] S400: In response to the total flow parameter being greater than or equal to the first threshold, the first diversion valve 51 is controlled to adjust the flow rate of the input pure water circuit 42 to zero, and the flow rate of the input alkaline water circuit 43 to the maximum, and the water quality parameter is obtained from the first water quality detection device 61.

[0089] S500: Determines whether the water quality parameter is less than the second threshold.

[0090] S600: In response to the water quality parameter being less than the second threshold, a filter replacement message is generated and sent using the communication component.

[0091] The method provided in this specific embodiment enables the monitoring of the lifespan of the water system using the total flow parameter measured by the first flow detection element 62. Furthermore, when the total flow parameter is greater than or equal to a first threshold, the water system is promptly adjusted to output water only from the alkaline water path 43. This allows the system to determine whether the alkaline filter element can still function properly to produce alkaline water based on water quality parameters. When the alkaline filter element malfunctions, a filter replacement message is sent to the user, significantly improving the usability of the mineral water purifier.
