Description

Technical Field

[0001] This application relates to the field of water treatment equipment technology, specifically to filter cartridges and mineral water purifiers. 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 method involves artificially mixing 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 a substrate containing alkaline substances to a container filled with water—such as a water dispenser or water purifier. The alkaline substances in the substrate dissolve into the water in the container, turning it into alkaline water. However, alkaline water prepared using this method is difficult to control effectively in terms of pH value; if the pH value is too high or too low, it will not achieve the desired effect for the user.

[0031] 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.

[0032] 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.

[0033] Currently, there are two common methods for preparing alkaline water. The first method involves artificially mixing 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 a substrate containing alkaline substances to a container filled with water—such as a water dispenser or water purifier. The alkaline substances in the substrate dissolve into the water in the container, turning it into alkaline water. However, alkaline water prepared using this method is difficult to control effectively in terms of pH value; if the pH value is too high or too low, it will not achieve the desired effect for the user.

[0034] 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.

[0035] See Figures 1-3 , Figure 1 This is a schematic diagram of the assembly structure of the filter element assembly provided in this application from one angle. Figure 2 This is a cross-sectional structural diagram of an embodiment of the filter element assembly provided in this application. Figure 3 This is a cross-sectional structural schematic diagram of another embodiment of the filter element assembly provided in this application. Specific embodiments of this application provide a filter element assembly 1 for treating fluids. 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 has a first chamber 11 and a second chamber 12. The first chamber 11 has a first inlet 112 and a first outlet 113, and the second chamber 12 has a second inlet 122 and a second outlet 123. A first alkaline filter material 111 is disposed in the first chamber 11, and a second alkaline filter material 121 is disposed in the second chamber 12. The filter element assembly 1 has a first alkaline water path through which the first alkaline filter material 111 can flow and a second alkaline water path through which the second alkaline filter material 121 can flow. The first alkaline water path and the second alkaline water path are arranged 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 path is different from that of the second alkaline water flowing out of the second alkaline water path.

[0038] In the structure provided in this specific embodiment, by connecting the first alkaline water path and the second alkaline water path in parallel, 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 can be mixed. This allows for the preparation of alkaline water with moderate alkalinity that meets the usage requirements by using the first alkaline water and the second alkaline water with different alkalinities. This reduces the probability that the pH value of the final effluent from the filter element assembly 1 is too high and improves the safety and stability of the filter element assembly 1.

[0039] In specific applications, the first alkaline filter material 111 can be a strongly alkaline filter material, and the second alkaline filter material 121 can be a weakly alkaline filter material. The alkalinity between the weakly alkaline and strongly alkaline filter materials can 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] 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] See Figure 7 , Figure 8 , Figure 7 The graph shows the pH value change trend of the first alkaline filter media and the second alkaline filter media when they are used individually. Figure 8The 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%.

[0047] Table 1

[0048]

[0049] Based on Table 1 and... Figure 7 , Figure 8 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.

[0050] 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.

[0051] 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 - The rapid dissolution causes the alkaline substances contained in the strongly alkaline filter material to be consumed quickly, which weakens the ability of filter element 1 to produce alkaline water in the later stages of use.

[0052] It should be noted that, Figure 7 , Figure 8The flow can involve different combinations of first alkaline filter media 111 and second alkaline filter media 121, 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 111 is not necessarily the same. Similarly, the alkalinity of the alkaline substances dissolved into the water by different second alkaline filter media 121 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.

[0053] Due to various reasons, Figure 7 The curve representing strongly alkaline wastewater shows the pH value over its service life, and... Figure 8 The pH values ​​of the curve representing strongly alkaline mineral water differ throughout its lifespan, but it is not difficult to see that... Figure 7 and Figure 8 The curves in the two samples show similar trends, and the same applies to weakly alkaline flowing water and weakly alkaline mineral water.

[0054] 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 a similar impact on the pH value of the alkaline water output by the water system.

[0055] In one specific embodiment of this application, the first alkaline filter material 111 contains a first alkaline substance, and the second alkaline filter material 121 contains a second alkaline substance. The dissolution rate of the first alkaline substance is greater than the dissolution rate of the second alkaline substance.

[0056] Because the first alkaline substance dissolves at a higher rate than the second alkaline substance, in the early to mid-stages of use of filter element 1, the pH value of the first alkaline water is higher than that of the second alkaline water. Mixing them together yields alkaline water with a suitable pH. In the later stages of use, the first alkaline substance is mostly dissolved, while the second alkaline substance, due to its slower dissolution rate, still maintains a certain amount of dissolution. This results in the first alkaline water having a lower pH and the second alkaline water having a higher pH. Mixing them together again yields alkaline water with a suitable pH.

[0057] Therefore, in the structure provided in this specific embodiment, by combining the first alkaline filter material 111 with the second alkaline filter material 121 with different dissolution rates, the pH value of the effluent can be kept relatively stable throughout the entire service life of the filter element assembly 1, avoiding the phenomenon that the pH value of the effluent is too high in the early stage of use and too low after a period of use. This can significantly improve the stability and usability of the filter element assembly 1 and effectively extend the service life of the filter element assembly 1.

[0058] In one specific embodiment of this application, the first alkaline filter material 111 and the second alkaline filter material 121 are respectively disposed in the first cavity 11 and the second cavity 12 along the axial direction of the filter element assembly 1. The filter element assembly 1 also includes a housing 13 and an isolation component 14. The first cavity 11 is disposed within the housing 13, the isolation component 14 is disposed within the first cavity 11, and the second cavity 12 is disposed within the isolation component 14. The first inlet 112, the first outlet 113, the second inlet 122, and the second outlet 123 are disposed within the housing 13.

[0059] The first alkaline water circuit includes a first internal water circuit 15 and a second internal water circuit 16. The second alkaline water circuit includes a third internal water circuit 17 and a fourth internal water circuit 18. One end of the first internal water circuit 15 is connected to the first inlet 112, and the other end is connected to the first cavity 11. One end of the second internal water circuit 16 is connected to the first outlet 113, and the other end is connected to the first cavity 11. One end of the third internal water circuit 17 is connected to the second inlet 122, and the other end is connected to the second cavity 12. One end of the fourth internal water circuit 18 is connected to the second outlet 123, and the other end is connected to the second cavity 12.

[0060] The structure provided in this specific embodiment isolates the first chamber 11 from the second chamber 12 using the isolation component 14, thereby achieving the parallel connection of the first alkaline water path and the second alkaline water path. This allows the second alkaline water flowing out of the second alkaline water path to be mixed with the first alkaline water flowing out of the first alkaline water path, resulting in a more suitable pH value for the final output water of the filter element assembly 1, which improves the safety and stability of the filter element assembly 1.

[0061] In one specific embodiment of this application, the isolation assembly 14 includes an annular isolation body 143 and a central tube 144. The central tube 144 is arranged along the axial direction of the filter element assembly 1, the annular isolation body 143 is sleeved on the outer periphery of the lower end of the central tube 144, and the first alkaline filter material 111 is sleeved on the outer periphery of the upper end of the central tube 144. A second inner water passage 16 is disposed inside the central tube 144, and the first alkaline filter material 111 is disposed between the second inner water passage 16 and the second inlet 122.

[0062] With the structure provided in this specific embodiment, the annular isolation body 143 and the first alkaline filter material 111 are respectively fitted onto the lower and upper sections of the central tube 144. The first cavity 11 and the second cavity 12 are coaxially arranged from top to bottom, forming a symmetrical and balanced structure within the filter element assembly 1. Furthermore, the central tube 144 connects the water outlet component and the second cavity 12, ensuring that the fluid flowing out of the second water outlet 123 can be filtered by the first alkaline filter material 111, thereby improving the stability of the filter element assembly 1.

[0063] Optionally, the housing 13 may include a first docking portion 131 and a second docking portion 132. The first docking portion 131 and the second docking portion 132 are disposed on the side surface of the housing 13 facing the inside of the first cavity 11. The isolation assembly 14 docks with the first docking portion 131 and the second docking portion 132, the first docking portion 131 connecting the second cavity 12 and the second water inlet 122, and the second docking portion 132 connecting the second cavity 12 and the second water outlet 123.

[0064] like Figure 2 As shown, the central tube 144 may include a horizontal baffle, with a first cavity 11 and a second cavity 12 respectively disposed on both sides of the horizontal baffle. A central channel is provided within the first alkaline filter material 111, and the upper end of the central tube 144 is fitted into this central channel. The housing 13 may include an end cap, which is placed over one end of the first alkaline filter material 111 to block one end of the central channel. The end of the first alkaline filter element away from the end cap abuts against the horizontal baffle. A second alkaline filter material 121 abuts against the horizontal baffle and the annular isolation body 143 along the circumference of the central tube 144.

[0065] Optionally, the annular isolation body 143 may include a third docking portion 141 and a fourth docking portion 142. The third docking portion 141 can be sleeved with the first docking portion 131, and the fourth docking portion 142 can be sleeved with the second docking portion 132, thereby docking the annular isolation body 143 with the housing 13.

[0066] Optionally, the housing 13 may also include a fifth docking portion 133, which can be sleeved with the lower end of the central tube 144, thereby docking the central tube 144 with the housing 13.

[0067] This application also provides a mineral water purifier, including a main body and a filter element assembly 1 as described in any of the above embodiments, wherein the filter element assembly 1 can be connected to the main body.

[0068] In the structure provided in this specific embodiment, the first alkaline water path and the second alkaline water path arranged in parallel in the filter element assembly 1 can be used to adjust 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. 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 water output from the filter element assembly 1 is too high, and can improve the safety and stability of the filter element assembly 1.

[0069] In one specific embodiment of this application, the main body of the device is provided with a first water outlet passage 21. The first water outlet passage 21 connects a first water outlet 113, a second water outlet 123, and a water outlet component.

[0070] In the structure provided in this specific embodiment, the first alkaline water flowing out through the first outlet 113 and the second alkaline water flowing out through the second outlet 123 both flow into the first water outlet path 21. The two types of water with different alkalinities can mix in the first water outlet path 21 and then flow to the water outlet component, so that when the user uses the water outlet component to take water, he can obtain the prepared alkaline water. The alkalinity of the alkaline water is moderate and can maintain the relative stability of the alkalinity of the water output by the filter element assembly 1, extend the service life of the filter element assembly 1, and improve the safety and stability of the filter element assembly 1.

[0071] See Figure 4 , Figure 4 This is a schematic diagram of the water circuit structure of the mineral water purifier provided in this application. In a specific embodiment of this application, the main body of the device includes a first inlet valve 231, a second inlet valve 232, and a controller. The main body of the device has a first inlet water path 23a and a second inlet water path 23b, which are arranged in parallel. The first inlet valve 231 is connected to the first inlet water path 23a, which is connected to the first inlet 112. The second inlet valve 232 is connected to the second inlet water path 23b, which is connected to the second inlet 122. The controller is connected to the first inlet valve 231 and the second inlet valve 232.

[0072] The structure provided in this specific embodiment allows the controller to effectively control the opening and closing of the first water inlet valve 231 and the second water inlet valve 232, thereby controlling the flow rate and velocity of the water flowing through the first alkaline filter material 111 via the first water inlet channel 23a and the water flowing through the second alkaline filter material 121 via the second water inlet channel 23b. This, in turn, allows the controller to control the ratio of the first alkaline water to the second alkaline water mixed in the first water outlet channel 21, thus achieving the regulation of the pH value of the water outlet component.

[0073] See Figure 5 , Figure 5 This is a schematic diagram of another water circuit structure for the mineral water purifier provided in this application. In a specific embodiment of this application, the main body of the device includes a first outlet valve 211, a second outlet valve 212, and a controller. The first outlet water circuit 21 includes a first branch 21a, a second branch 21b, and a confluence water circuit 21c. The first outlet valve 211 is connected to the first branch 21a, one end of which is connected to the first outlet 113, and the other end of which is connected to the confluence water circuit 21c. The second outlet valve 212 is connected to the second branch 21b, one end of which is connected to the second outlet 123, and the other end of which is connected to the confluence water circuit 21c. The end of the confluence water circuit 21c away from the first branch 21a and the second branch 21b is connected to the water outlet component. The controller is connected to the first outlet valve 211 and the second outlet valve 212.

[0074] With the structure provided in this specific embodiment, the controller can control the opening and closing of the first outlet valve 211 and the second outlet valve 212, thereby controlling the flow rate and velocity of the first alkaline water flowing out through the first branch 21a and the second alkaline water flowing out through the second branch 21b, and thus controlling the ratio of the first alkaline water to the second alkaline water flowing into the confluence water path 21c, thereby achieving the regulation of the pH value of the water outlet component.

[0075] See Figure 6 , Figure 6 This is another schematic diagram of the water circuit structure of the mineral water purifier provided in this application. In a specific embodiment of this application, the main body of the device includes a water quality detection component 24, which is connected to a controller. The water quality detection component 24 is installed in the first branch 21a and / or the second branch 21b.

[0076] Optionally, the water confluence channel 21c may also be equipped with a water quality detection component 24.

[0077] In the structure provided in this specific embodiment, the water quality detection component 24 is set in the water confluence channel 21c to directly characterize the water quality of the water outlet component. The water quality detection component 24 is set in the first branch 21a and / or the second branch 21b to measure the water quality of the first alkaline water and / or the second alkaline water. Based on 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 adjust to the specified pH range can be calculated.

[0078] 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. This allows the controller to adjust at least one of the valves, such as the first inlet valve 231, the second inlet valve 232, the first outlet valve 211, and the second outlet valve 212, based on the water quality feedback. This improves the accuracy of the mineral water purifier in regulating the alkalinity of the output water, enabling the mineral water purifier to output water that better meets the user's needs and enhancing the usability of the mineral water purifier.

[0079] In one specific embodiment of this application, the water quality detection component 24 may include at least one of a pH sensor and a TDS sensor.

[0080] In the structure provided in this embodiment, the pH sensor is used to detect the hydrogen ion concentration in the analyte and can 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 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.
