It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0032] With the improvement of productivity, people's demand for quality of life and convenience is also increasing. Alkaline water is a kind of water with a pH value greater than 7. Drinking alkaline water in moderation can replenish water, improve microcirculation, and promote metabolism. At the same time, alkaline water also has an improvement function in the case of water and electrolyte disorders. For example, after a lot of vomiting, drinking alkaline water can help replenish water. In addition, alkaline water can also help neutralize excess gastric acid, protect gastric mucosa, and reduce the possibility of peptic ulcers. Therefore, mineralized water is widely favored as drinking water. At the same time, there is also a certain demand for alkaline water during production and experiments.

[0033] At present, there are two common ways to prepare alkaline water. The first is to manually mix alkaline substances with water to make alkaline water with a suitable pH value, but this method is very troublesome, has a certain chemical knowledge threshold and is inefficient. The second is to put a substrate containing alkaline substances into a container filled with water, such as a drinking fountain or a water purifier. The alkaline substances in the substrate can dissolve into the water in the container, turning the water into alkaline water. However, it is difficult to effectively control the pH value of alkaline water prepared by this method. When the pH value is too high or too low, it cannot achieve the desired effect of the user.

[0034] In order to improve or solve the above technical problems, the inventors of the present application have proposed at least the following embodiments after long-term research.

[0035] See also Figure 1 to Figure 3 , Figure 1 A schematic diagram of the assembly structure of the filter element assembly provided in this application at one angle. Figure 2 A schematic cross-sectional view of an embodiment of a filter element assembly provided in the present application. Figure 3 This is a cross-sectional structural schematic diagram of another embodiment of the filter element assembly provided by the present application. The specific embodiment of the present application provides a filter element assembly 1 for treating a fluid, and the filter element assembly 1 may include a first alkaline filter material 111 and a second alkaline filter material 121 .

[0036] The filter element assembly 1 is provided with a first cavity 11 and a second cavity 12. The first cavity 11 is provided with a first water inlet 112 and a first water outlet 113. The second cavity 12 is provided with a second water inlet 122 and a second water outlet 123. The first alkaline filter material 111 is provided in the first cavity 11, and the second alkaline filter material 121 is provided in the second cavity 12. The filter element assembly 1 is provided with a first alkaline waterway that can flow through the first alkaline filter material 111 and a second alkaline waterway that can flow through the second alkaline filter material 121. The first alkaline waterway and the second alkaline waterway are provided in parallel.

[0037] The alkalinity of the first alkaline filter material 111 is greater than that of the second alkaline filter material 121 , so that the alkalinity of the first alkaline water flowing out of the first alkaline water channel is different from the alkalinity of the second alkaline water flowing out of the second alkaline water channel.

[0038] In the structure provided in this specific embodiment, the first alkaline water channel and the second alkaline water channel arranged in parallel can be used to prepare the first alkaline water flowing through the first alkaline filter material 111 and the second alkaline water flowing through the second alkaline filter material 121, so that the first alkaline water and the second alkaline water with different alkalinities can be used to prepare alkaline water with moderate alkalinity that meets the use requirements for use, which can reduce the probability of the pH value of the final water output from the filter element assembly 1 being too high, and can improve the safety and stability of the filter element assembly 1.

[0039] In a specific application, the first alkaline filter material 111 may be a strong alkaline filter material, and the second alkaline filter material 121 may be a weak alkaline filter material. The alkalinity between the weak alkaline filter material and the strong alkaline filter material may be a relative concept, that is, the alkalinity of the first alkaline filter material 111 is higher than that of the second alkaline filter material 121.

[0040] The strong alkaline filter material can be made of strong alkaline materials, such as at least one of brucite, periclase, sepiolite, magnesite and the like. Taking brucite as an example, brucite contains Mg(OH)2, which enables brucite to react in water to release (dissolve) OH - , which can enhance the alkalinity of the water body and increase the pH value of the water body to obtain alkaline water.

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

[0042] The weakly alkaline filter material can be made of weakly alkaline materials, such as at least one of calcite, dolomite, stalactite, limestone, Iceland spar, etc. Taking calcite as an example, calcite contains CaCO3. When calcite is immersed in water, reaction B will first occur to release CO3 in the water. 2- , then CO3 2- Can undergo hydrolysis reaction with H2O to generate OH - .

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

[0044] Reaction C: CO3 2- +H2OHCO3 - +OH -

[0045] It can be found that the strong alkaline filter material only needs one step reaction to obtain OH - , weakly alkaline filter materials require two steps of reaction to obtain OH - , and the rate of reaction C is much lower than that of reaction A, so the strong alkaline material will preferentially dissolve OH into the water. - Moreover, reaction C is a reversible reaction. When reaction A occurs first, the chemical equilibrium of reaction C will shift to the left. Therefore, the strong alkaline filter material can inhibit the OH of the weak alkaline filter material. - release.

[0046] See also Figure 7 , Figure 8 , Figure 7 This is a trend chart of pH value changes of water flowing through the first alkaline filter material and the second alkaline filter material alone. Figure 8The pH value change trend diagram of the first alkaline filter material alone, the second alkaline filter material alone, and the mixed water. The following multiple embodiments are obtained by adjusting the mass ratio of the strong alkaline filter material to the weak alkaline filter material. The pH value of the water flowing through each embodiment at different flow rates is tested, and Table 1 is obtained as follows. Among them, the adjustment range of the mass ratio of the strong alkaline filter material is 10% to 50%, and correspondingly, the adjustment range of the mass ratio of the weak alkaline filter material is 50%-90%.

[0047] Table 1

[0048]

[0049]

[0050] Based on Table 1 Figure 7 , Figure 8 According to analysis, when the proportion of strong alkaline filter material is 0%, that is, there is only weak alkaline filter material, due to the slow dissolution rate of the weak alkaline filter material itself and poor ability to alkalize water quality, the pH value of the water outlet is less than 7 when the first 2000L of water flows through, and alkaline water that meets water demand cannot be obtained in the early stage. Afterwards, as the flow rate increases, the pores inside the weak alkaline material gradually become connected from closed under the impact of water flow, and the water flow can pass not only from the surface of the material, but also from the inside of the material, which increases the contact area between water molecules and mineralized materials, increases the reaction rate, and gradually increases the pH value of the flowing water to above 7.

[0051] When the proportion of strong alkaline filter material increases to 5%, the pH value at 0L increases. This is because the strong alkaline filter material releases OH into the flowing water at the beginning. - When the proportion of strong alkaline filter material is between 10-50%, the pH value can be maintained between 7.0-9.0 throughout the life span, thus obtaining alkaline water that meets water demand.

[0052] When the strong alkaline filter material accounts for 60%, the pH value at the beginning reaches 9.15, which exceeds the range of weak alkaline water and does not meet the water demand. When the strong alkaline filter material accounts for 100%, the pH value at the beginning reaches 10.12, far exceeding the upper limit of 9, and decays quickly. When the flow rate reaches 6000L, the pH value is less than 7. This is because the strong alkaline material releases OH into the flow water. - Strong ability, but due to OH - Too fast dissolution causes the alkaline substances contained in the strong alkaline filter material to be consumed quickly, so that the alkaline water production capacity of the filter element assembly 1 is weakened in the later period of use.

[0053] It should be noted that Figure 7 , Figure 8The method may be a combination of different first alkaline filter materials 111 and second alkaline filter materials 121, or the flow rate and / or flow velocity of the flowing water body may be different. The alkalinity of the alkaline substances dissolved into the water body by different first alkaline filter materials 111 may not be the same. The alkalinity of the alkaline substances dissolved into the water body by different second alkaline filter materials 121 may not be the same. The amount of alkaline substances contained in the flowing water with different flow rates and / or flow velocities may not be the same.

[0054] Due to many reasons, Figure 7 The curve representing the strong alkaline water flow shows the pH value during the service life cycle, which is different from Figure 8 The curve representing the strongly alkaline mineral water shows different pH values ​​during its service life, but at the same time, it is not difficult to see Figure 7 and Figure 8 The curves in have similar changing trends, and the same is true for weak alkaline flow water and weak alkaline mineral water.

[0055] Therefore, although the specific values ​​are different, the combination of the first alkaline filter material 111 and the second alkaline filter material 121 can have similar effects on the pH value of the alkaline water output by the water system.

[0056] In a specific embodiment of the present application, the first alkaline filter material 111 contains a first alkaline substance, the second alkaline filter material 121 contains a second alkaline substance, and the dissolution rate of the first alkaline substance is greater than the dissolution rate of the second alkaline substance.

[0057] Since the dissolution rate of the first alkaline substance is relatively high, while the dissolution rate of the second alkaline substance is relatively low, in the early and middle stages of the use of the filter element assembly 1, the pH value of the first alkaline water is relatively high while the pH value of the second alkaline water is relatively low. Alkaline water with a moderate pH value can be obtained by mixing the two. In the middle and late stages of the use of the filter element assembly 1, the first alkaline substance is basically completely dissolved, while the second alkaline substance still maintains a certain amount of dissolution due to its slow dissolution rate, making the pH value of the first alkaline water relatively low while the pH value of the second alkaline water relatively high. Alkaline water with a moderate pH value can also be obtained by mixing the two.

[0058] Therefore, in the structure provided in this specific embodiment, by cooperating with the first alkaline filter material 111 and the second alkaline filter material 121 having different dissolution rates, the pH value of the outlet water can be kept relatively stable during the entire use cycle of the filter element assembly 1, thereby avoiding the occurrence of the phenomenon that the pH value of the outlet water is too high at the beginning of use and the pH value of the outlet water is too low after a period of use. This can significantly improve the stability and availability of the filter element assembly 1 and effectively extend the service life of the filter element assembly 1.

[0077] Optionally, the combined water channel 21c may also be provided with a water quality detection component 24.

[0078] In the structure provided in this specific embodiment, a water quality detection component 24 is arranged in the confluent water channel 21c, which can intuitively characterize the water quality of the water output from the water output component. A water quality detection component 24 is arranged in the first branch 21a and / or the second branch 21b, which can measure the water quality of the first alkaline water and / or the second alkaline water. Through the water quality of the first alkaline water and / or the second alkaline water, the ratio of the first alkaline water and the second alkaline water required to be adjusted to a specified pH range can be calculated.

[0079] Therefore, by setting up the water quality detection component 24, the water quality of the water in the filter element component 1 can be effectively monitored, so that the controller can adjust at least one of the valve bodies such as the first water inlet valve 231, the second water inlet valve 232, the first water outlet valve 211, and the second water outlet valve 212 according to the feedback of the water quality, which can improve the accuracy of the mineral water purifier in regulating the alkalinity of the water outlet, enable the mineral water purifier to output water that better meets the needs of users, and improve the availability of the mineral water purifier.

[0080] In a specific embodiment of the present application, the water quality detection component 24 may include at least one of a pH sensor and a TDS sensor.

[0081] In the structure provided in this embodiment, the pH sensor is used to detect the hydrogen ion concentration in the object being measured, and can convert it into a corresponding usable output signal, thereby being able to characterize the pH value of the water body. The TDS sensor is a device for measuring the total dissolved solids (TDS) in water, which can continuously monitor the conductivity value in the object being measured. The pH value of the object being measured can be calculated based on the conductivity value, thereby being able to characterize the pH value of the water body.
