Description

Technical Field

[0001] This application relates to the field of mineral filtration technology, and more particularly to a filter element and its design, preparation method, filter cartridge, water circuit system and mineral water purifier. Background Technology

[0002] With social development and the improvement of people's living standards, people consume more meat in their daily lives, leading to a trend of slightly acidic diets for many. In addition, the fast pace of life, with staying up all night becoming the norm for young people, and the increasing prominence of environmental problems in recent years, coupled with the lack of exercise and life pressures among urban residents, have resulted in many people having acidic constitutions, which may lead to a series of sub-health risks.

[0003] Most alkaline filter cartridges on the market use weakly alkaline filter media. After a period of use, their alkalinity decreases, while tap water is mostly weakly acidic. Weakly alkaline filter media is not capable of alkalizing the water quality and cannot alkalize the water as designed. As a result, the filter cartridges have a short service life, require frequent replacement, have high application costs, and provide a relatively poor user experience. Summary of the Invention

[0061] This invention provides a filter element design method for designing alkaline filter elements, comprising the following steps:

[0062] refer to Figure 3 and Figure 4 The design includes a first alkaline filter material 110 and a second alkaline filter material 120. The second alkaline filter material 120 is designed to inhibit the dissolution of alkaline substances in water bodies with a pH value higher than the set value. That is, when the second alkaline filter material 120 is in water bodies with a pH value higher than the set value (strong alkalinity), it is inhibited from releasing (dissolving) alkaline substances.

[0063] The alkalinity of the first alkaline filter material 110 is designed to be higher than that of the second alkaline filter material 120. For ease of understanding, the first alkaline filter material 110 is defined as a strongly alkaline filter material, and the second alkaline filter material 120 is defined as a weakly alkaline filter material. The design is that the pH value of the water flowing through the first alkaline filter material 110 is higher than the set pH value in the early stage, and lower than the set pH value in the later stage. The design is that the first alkaline filter material 110 dissolves alkaline substances in the early stage and inhibits the dissolution of alkaline substances in the second alkaline filter material 120; the design is that the first alkaline filter material 110 and the second alkaline filter material 120 dissolve alkaline substances in the middle and later stages, respectively. That is, the first alkaline filter material 110 inhibits the dissolution of alkaline substances in the second alkaline filter material 120 in the early stage, and as the alkalinity of the first alkaline filter material 110 decreases in the later stage, it will alleviate the inhibition of the dissolution of alkaline substances in the second alkaline filter material 120, allowing the second alkaline filter material 120 to gradually dissolve alkaline substances.

[0064] Figure 1 The graph shows the pH trend of water (pure water) flowing through the first alkaline filter media 110 and the second alkaline filter media 120 in the same chamber. It can be seen that the strongly alkaline water formed by the first alkaline filter media 110 (strong alkaline) initially meets the alkaline water quality requirements, but due to rapid dissolution, it becomes difficult to meet the alkaline water quality requirements (pH 7.0 to pH 9.0) in the later stages. The weakly alkaline material in the second alkaline filter media 120 forms weakly alkaline water. Because the weakly alkaline material itself dissolves slowly and has poor alkalization ability, it cannot meet the alkaline water quality requirements initially. However, due to gradual surface dissolution, the pores inside the weakly alkaline material gradually become interconnected, allowing water to pass not only through the surface but also through the interior of the material. This increases the contact area between water molecules and the weakly alkaline material, increasing the dissolution rate, thus allowing the pH to meet the alkaline water quality requirements in the later stages. Using either strongly alkaline or weakly alkaline materials alone has certain shortcomings and cannot simultaneously meet the requirements of the filter cartridge's lifespan. In this embodiment, when the filter element is in a combined application of the first alkaline filter material 110 and the second alkaline filter material 120, both are immersed in water during non-water production periods (immersion). When the concentration of alkaline ions precipitated from the strong alkaline minerals in the first alkaline filter material 110 is high, it inhibits the weak alkalinity in the second alkaline filter material 120, thereby slowing down mineral consumption and increasing the overall mineralization lifespan. Since weak alkali can enhance porosity release in an alkaline environment, the porosity of the weak alkaline minerals is low in the early stages. Under the action of the weak alkaline water regulated by strong alkali, the internal porosity gradually increases, thereby enhancing its alkalization capacity. Once the porosity reaches a certain level, it enters a stable dissolution stage, at which point the dissolution capacity of the strong alkaline minerals decreases. This combination effectively meets the design objective of extending the filter element's lifespan, and the pH value of the effluent can remain between 7.0 and 9.0 throughout the entire lifespan. Figure 2This is a graph showing the pH trend of water (pure water) flowing through another set of first alkaline filter media 110 and second alkaline filter media 120. Figure 2 The first alkaline filter media 110 corresponds to strongly alkaline mineral water, and the second alkaline filter media 120 corresponds to weakly alkaline mineral water. The final mixed water is a water body composed of a equiproportionate mixture of strongly alkaline and weakly alkaline mineral water. In the early stages, the strongly alkaline mineral water releases alkaline ions rapidly, exceeding the required range, and is consumed quickly. Conversely, the weakly alkaline mineral water has a weaker initial release capacity, below the required range, but its consumption is slower and more stable in the later stages. Therefore, a combination of strong and weak alkaline materials is used, allowing the strong alkaline material to play a dominant role in regulating the water quality to the required range in the early stages. Later, as the strong alkaline material is consumed to a certain extent, the weak alkaline material gradually takes effect and dominates the water quality regulation to a stable range. The first alkaline filter media 110 and the second alkaline filter media 120 can be installed in the same chamber, with two water streams flowing through the first alkaline filter media 110 and the second alkaline filter media 120 respectively during water production. During non-water production periods (soaking), the soaking water is interconnected, with both strong and weak alkali ores immersed simultaneously. The higher concentration of alkaline ions released from the strong alkali ores inhibits the release of weak alkali ores, further slowing down ore consumption and extending the overall mineralization lifespan. By combining the rapidly depleting strong alkali in the early stages with the stable release of weak alkali later, the entire filter cartridge can consistently provide the required water quality throughout its lifespan.

[0065] Through the above design scheme, in the early stage of the filter cartridge, the first alkaline filter material 110 preferentially dissolves alkaline substances, making the pH value of the water higher than the set pH value. This inhibits the dissolution of alkaline substances in the second alkaline filter material 120, allowing the second alkaline filter material 120 to maintain its alkalization ability. As the filter cartridge is used, the alkalization ability of the first alkaline filter material 110 decreases, causing the pH value of the water to gradually decrease. Its inhibitory effect on the second alkaline filter material also gradually eases, allowing the second alkaline filter material to gradually and slowly release alkaline substances. The first alkaline filter material 110 and the second alkaline filter material 120 can work synergistically, enabling the filter cartridge to continue to effectively alkalize the water in the middle and later stages of its lifespan, keeping the pH value of the water within the standard range. This provides users with long-lasting alkalized water that meets the pH standard range, satisfying users' high-end drinking water needs. The filter cartridge has a long service life, eliminating the need for frequent filter replacements and providing a superior user experience.

[0066] The present invention also provides a filter element, which can be designed using the above-described design method. The filter element includes a first alkaline filter material 110 and a second alkaline filter material 120. The alkalinity of the first alkaline filter material 110 is higher than that of the second alkaline filter material 120. The second alkaline filter material 120 is inhibited from dissolving alkaline substances in water with a pH value higher than a set value. When the first alkaline filter material 110 initially dissolves alkaline substances, the pH value of the water is higher than the set pH value. When the first alkaline filter material 110 later dissolves alkaline substances, the pH value of the water is lower than the set pH value. The first alkaline filter material 110 and the second alkaline filter material 120 are disposed in the same filter chamber. The first alkaline filter material 110 and the second alkaline filter material 120 are immersed in the water in the filter chamber. When the alkaline water in the filter chamber is higher than the set pH value, the alkaline substances in the second alkaline filter material 120 are inhibited and cannot (virtually cannot) dissolve. This design has a simple structure and can be used as an integrated filter element. Alternatively, the first alkaline filter material 110 and the second alkaline filter material 120 can be disposed in different filter chambers and connected by pipelines. In this way, the water flows through the first alkaline filter material 110 first and then to the second alkaline filter material 120. The high pH alkaline water obtained by flowing through the first alkaline filter material 110 can inhibit the dissolution of alkaline substances in the second alkaline filter material 120. As the water flow rate increases, the alkalization capacity of the first alkaline filter material 110 gradually decreases, so that the pH value of the water flowing to the second alkaline filter material gradually decreases. The inhibitory effect of the first alkaline filter material 110 on the second alkaline filter material is also gradually relieved. When the pH value is lower than the set pH value, the second alkaline filter material can also gradually and slowly release alkaline substances. The first alkaline filter material 110 and the second alkaline filter material 120 can work together to alkalize the water, which greatly improves the service life of the filter element.

[0067] Specifically, as a first possible implementation, the first alkaline filter material 110 and the second alkaline filter material 120 are mixed and then formed into a filter body, that is, the first alkaline filter material 110 and the second alkaline filter material 120 are fully mixed and then pressed or sintered into a filter body with an integral structure. The carrier of the filter body can be carbon rod filter material, carbon fiber filter material, carbon particle filter material, or ceramic filter material, etc. In specific applications, the alkaline filter material can be mixed into the material of the substrate, or it can be attached to the surface of the substrate or dispersed inside the substrate, etc.

[0068] As a second possible implementation, the first alkaline filter material 110 and the second alkaline filter material 120 are integrally formed into a filter body along a predetermined direction. That is, along the predetermined direction, a portion of the structure is the first alkaline filter material 110 (first filter body), and a portion of the structure is the second alkaline filter material 120 (second filter body). In specific applications, the first alkaline filter material 110 and the second alkaline filter material 120 can be columnar or cylindrical, etc. The first alkaline filter material 110 and the second alkaline filter material 120 can be integrally formed along the axial direction. The filter body as a whole can be columnar or cylindrical. Taking the vertical direction along the axial direction as an example, the upper part can be the first alkaline filter material 110, and the lower part can be the second alkaline filter material 120 (see reference). Figure 4 (As shown). The first alkaline filter material 110 and the second alkaline filter material 120 are integrally molded to form a filter body (see reference). Figure 5 (As shown).

[0069] As a third possible implementation, the first alkaline filter material 110 and the second alkaline filter material 120 are respectively formed and assembled along the setting direction to form a filter body; the first alkaline filter material 110 and the second alkaline filter material 120 are respectively formed into a first filter body and a second filter body, and the first filter body and the second filter body can be stacked one on top of the other to form a filter body (see reference). Figure 4 As shown), the first and second filter bodies can also be arranged inside and outside to form a filter body (see reference). Figure 5 As shown), for example, the first alkaline filter material 110 and the second alkaline filter material 120 are columnar or cylindrical. The first alkaline filter material 110 and the second alkaline filter material 120 are integrally formed or separately formed and fixedly connected along the axial direction to form a filter body. The first alkaline filter material 110 and the second alkaline filter material 120 can be bonded together or connected by end caps. When the first alkaline filter material 110 and the second alkaline filter material 120 are cylindrical, they can also be connected by a central tube, so that the first alkaline filter material 110 and the second alkaline filter material 120 are sleeved on the central tube along the axial direction. Alternatively, the first alkaline filter material 110 and the second alkaline filter material are separately formed and fixedly connected to form a filter body, that is, the first alkaline filter material 110 and the second alkaline filter body are arranged in the radial direction, and the first alkaline filter material 110 can be cylindrical and sleeved on the outside of the second alkaline filter material 120. Alternatively, the first alkaline filter material 110 can be installed inside the filter housing, and the second alkaline filter material 120 can be connected to the outside of the filter housing, both being housed within the same filter cartridge 200 (see reference). Figure 6 (As shown).

[0070] As a fourth possible implementation, the first alkaline filter material 110 and the second alkaline filter material 120 are arranged in a set direction to form a filter body, so that the alkalinity of the filter body changes in the set direction, that is, the alkalinity of the filter body changes linearly or non-linearly along the set direction.

[0071] Of course, in specific applications, the combination of the first alkaline filter material 110 (first filter body) and the second alkaline filter material 120 (second filter body) is not limited to the above scheme. They can also be combined and connected by layering, covering and other methods, which will not be elaborated here.

[0072] Specifically, in the first alkaline filter material 110 and the second alkaline filter material 120, the mass percentage of the first alkaline filter material 110 is 10%-50%, and the mass percentage of the second alkaline filter material 120 is 50%-90%, that is, the mass percentages of the strongly alkaline material and the weakly alkaline material are 10%-50% and 50%-90%, respectively. In specific applications, in the first alkaline filter material 110 and the second alkaline filter material 120, the mass percentage of the first alkaline filter material 110 is 15% to 45%, and the mass percentage of the second alkaline filter material 120 is 55% to 85%. For example, the first alkaline filter material 110 may have a mass percentage of 20%, and the second alkaline filter material 120 may have a mass percentage of 80%; or, the first alkaline filter material 110 may have a mass percentage of 25%, and the second alkaline filter material 120 may have a mass percentage of 75%; or, the first alkaline filter material 110 may have a mass percentage of 30%, and the second alkaline filter material 120 may have a mass percentage of 70%; or, the first alkaline filter material 110 may have a mass percentage of 35%, and the second alkaline filter material 120 may have a mass percentage of 65%; or, the first alkaline filter material 110 may have a mass percentage of 40%, and the second alkaline filter material 120 may have a mass percentage of 60%; or, the first alkaline filter material 110 may have a mass percentage of 45%, and the second alkaline filter material 120 may have a mass percentage of 55%; or, both the first alkaline filter material 110 and the second alkaline filter material 120 may have a mass percentage of 50%. It should be noted that the first alkaline filter material 110 may include one or more alkaline materials, and its equivalent alkalinity can be obtained from calculated or measured values. The first alkaline filter media 110 may include one or more alkaline materials, the equivalent alkalinity of which can be obtained by calculation or measurement. Table 1 shows the pH values ​​of the flowing water (outflow) at different flow rates when pure water passes through at a set flow rate, with different proportions (mass ratios) of strongly alkaline materials in the first alkaline filter media 110 and the second alkaline filter media 120.

[0073] Table 1

[0074]

[0075] It is evident that when the proportion of strongly alkaline material is 0%, i.e., only weakly alkaline material is present, the pH value of the effluent is less than 7 during the first 2000L of water flow, and then the pH value gradually increases to above 7. This is due to the slow dissolution rate and poor alkalization ability of the weakly alkaline material itself. As the flow rate increases, the pH gradually increases to above 7. This is because, with the impact of the water flow, the pores inside the weakly alkaline material gradually become interconnected, allowing water to pass not only through the surface of the material but also through its interior, increasing the contact area between water molecules and the weakly alkaline material, and thus increasing the dissolution rate of the weakly alkaline material. When the proportion of strongly alkaline material increases to 5%, the pH value in the initial stage (0L) is somewhat improved. This is because the addition of 5% strongly alkaline material allows it to exert its alkalization ability in the initial stage, thus raising the pH value in the early stages. When the proportion of strongly alkaline material is 10%, the pH value can be maintained above 7.01 throughout the entire lifespan. When the proportion of strongly alkaline material is 40%, the initial pH value can reach 8.25; when the proportion reaches 60%, the initial pH value reaches 9.15, exceeding the range of weakly alkaline water; when the proportion of strongly alkaline material is 100%, the initial pH value reaches 10.12, exceeding the upper limit of 9, and decays rapidly. When the flow rate reaches 6000L, the pH value is already less than 7. This is because while strongly alkaline materials have strong alkalizing properties, their rapid dissolution leads to material consumption and weakens their mineralization capacity in the later stages. In this embodiment, the proportion of strongly alkaline material is 10%-50%, which ensures that the initial effluent pH can reach between 7.01 and 8.89, meeting the standard of an effluent pH value between 7.0 and 9.0, and avoiding excessively high effluent pH values. Meanwhile, since the weak alkaline material accounts for 50% to 90%, it can work synergistically with the strong alkaline material, so that the overall life of the filter element can reach a flow rate of more than 7200L. Compared with the 2000L life of ordinary filter elements, the life of the filter element provided in this embodiment is greatly improved.

[0076] Specifically, the first alkaline filter material 110 includes at least one of brucite, periclase, sepiolite, and magnesite.

[0077] Specifically, the second alkaline filter material 120 includes at least one of calcite, dolomite, stalactite, limestone, and Iceland spar. The first alkaline filter material 110 can be a binary alkali material, which can combine with metal elements beneficial to the human body, such as magnesium hydroxide and calcium hydroxide. The second alkaline filter material 120 can use calcium carbonate as a raw material.

[0078] Specifically, the first alkaline filter material 110 uses carbon rod filter material, carbon fiber filter material, carbon particle filter material or ceramic filter material as a carrier; that is, the filter body formed by the first alkaline filter material 110 can be in the form of carbon rod, carbon fiber, carbon particle or ceramic filter body.

[0079] The second alkaline filter material 120 uses carbon rod filter material, carbon fiber filter material, carbon particle filter material or ceramic filter material as a carrier; that is, the filter body formed by the second alkaline filter material 120 can be in the form of carbon rod, carbon fiber, carbon particle or ceramic filter body.

[0080] The present invention also provides a method for preparing a filter element, which includes the following steps:

[0081] Raw material acquisition steps: Obtain the raw materials for the first alkaline filter material 110 and the second alkaline filter material 120 respectively;

[0082] Cleaning and drying steps: The raw materials of the first alkaline filter material 110 and the second alkaline filter material 120 are cleaned and then dried;

[0083] Crushing step: Crush the raw materials of the first alkaline filter material 110 and the second alkaline filter material 120 to the set mesh size;

[0084] Impurity removal step: The pulverized first alkaline filter material 110 and second alkaline filter material 120 are subjected to impurity removal treatment to obtain raw material powder;

[0085] Molding steps: The raw material powder after impurity removal is mixed with the carrier powder according to the set mass ratio and then molded into a filter body.

[0086] Specifically, the raw materials for the first alkaline filter material 110 and the second alkaline filter material 120 can be mineral raw materials. In the cleaning and drying steps, the cleaned raw materials are dried at 120 degrees Celsius for a set time (2 hours) to remove bacteria and other organic matter adsorbed on the surface of the mineral.

[0087] Specifically, in the crushing step, the ore raw material is crushed by crushing equipment and screened to obtain powder particles of 20-200 mesh.

[0088] Specifically, in the impurity removal step, the powder particles are subjected to high-temperature treatment again at a set temperature (120 degrees Celsius) to remove impurities such as organic matter adsorbed inside the ore.

[0089] Specifically, the pulverized first alkaline filter material 110 and second alkaline filter material 120 are mixed with carrier powder and then formed into a single filter body; or, the first alkaline filter material 110 is mixed with carrier powder and formed into a first alkaline filter body; the second alkaline filter material 120 is mixed with carrier powder and formed into a second alkaline filter body. Specifically, the first alkaline filter body and the second alkaline filter body can be integrally connected; or, the first alkaline filter body and the second alkaline filter body can be bonded or connected by a fixing structure.

[0090] In practical applications, mineral powder (powder particles) is mixed with carbon powder and adhesive powder, and then made into composite carbon rods using carbon rod forming equipment, thus obtaining a long-lasting weakly alkaline mineralized filter element.

[0091] The present invention also provides a filter cartridge, such as Figures 4 to 6 As shown, the system includes a shell 200, within which the aforementioned filter element is disposed. The shell 200 may have a filter element inlet and an outlet, and an internal water passage is provided within the shell 200. This allows water to flow simultaneously or sequentially through a first alkaline filter element and a second alkaline filter element. The first alkaline filter element contains a strongly alkaline material, and the second alkaline filter element contains a weakly alkaline material. The synergistic mineralization mechanism of the first and second alkaline filter elements lies in the fact that when both materials are present, a smaller amount of the strongly alkaline material is used in combination with a larger amount of the weakly alkaline material, for example, 30% strongly alkaline material and 70% weakly alkaline material. In the early stages of use, the strongly alkaline material preferentially precipitates (dissolves), and the mineralization function of the weakly alkaline material is inhibited. At this time, the pH value is less than 9. As the usage time increases, the strongly alkaline material is consumed more, and the mineralization function of the weakly alkaline material gradually becomes dominant, extending the overall service life of the filter element.

[0092] Specifically, the cylindrical shell 200 is provided with a filter cavity for simultaneously accommodating the first alkaline filter material 110 and the second alkaline filter material 120; that is, the first alkaline filter material 110 and the second alkaline filter material 120 are disposed in the same filter cavity, and the first alkaline filter material 110 and the second alkaline filter material 120 can be disposed vertically or internally.

[0093] Alternatively, the shell 200 may be provided with a series water passage for sequential flow through the first alkaline filter material 110 and the second alkaline filter material 120, for reference. Figure 3 As shown.

[0094] Specifically, the first alkaline filter material 110 and the second alkaline filter material 120 are arranged sequentially inside the shell 200 along the water flow direction inside the filter cartridge.

[0095] Specifically, the filter cartridge is provided with a first compartment and a second compartment, the first alkaline filter material 110 is disposed in the first compartment, and the second alkaline filter material 120 is disposed in the second compartment; the series water circuit is connected in series to the first compartment and the second compartment.

[0096] The present invention also provides a water system, see reference. Figure 3 and Figure 7As shown, it includes an inlet pipe 161 and an outlet pipe 162. The aforementioned filter element (first alkaline filter material 110 and second alkaline filter material 120) is disposed between the inlet pipe 161 and the outlet pipe 162. The first alkaline filter material 110 and the second alkaline filter material 120 are disposed in the water system along the direction from the inlet pipe 161 to the outlet pipe 162. The first alkaline filter media 110 contains strong alkaline minerals, which have a strong ability to adjust the pH value of the water flow in the early stage and the alkaline ions are released quickly, but the consumption rate is also fast. The second alkaline filter media 120 contains weak alkaline minerals, which have a weak ability to adjust the pH value of the water flow in the early stage, but the consumption is slower and more stable in the later stage. Therefore, the first alkaline filter media 110 (strong alkaline filter media) and the second alkaline filter media 120 (weak alkaline filter media) can be connected in series. In the early stage, the water flow is adjusted to the required water quality range by the first alkaline filter media 110 (strong alkaline filter media). When the first alkaline filter media 110 (strong alkaline filter media) is consumed to a certain extent, the second alkaline filter media 120 (weak alkaline filter media) slowly takes effect and dominates the adjustment of the water quality to a stable range in the later stage.

[0097] Specifically, such as Figure 7 As shown, the water system includes a series-parallel switching water circuit, which comprises a first water circuit 141 and a second water circuit 142 in parallel. The first water circuit 141 and the second water circuit 142 are connected between the inlet pipe 161 and the outlet pipe 162. The first water circuit 141 is provided with the first alkaline filter material 110, and the second water circuit 142 is provided with the second alkaline filter material 120. The first water circuit 141 is provided with a first control valve 151, which can control the flow rate or on / off state of the first water circuit 141. The first control valve 151 can be located downstream of the first alkaline filter material 110. The second water circuit 142 is provided with a second control valve 152, which can be located upstream of the second alkaline filter material 120, and can control the flow rate or on / off state of the second water circuit 142. The upstream of the first water path 141 and the second water path 142 are connected to the inlet pipe 161, and the downstream of the first water path 141 and the second water path 142 are connected to the outlet pipe 162. A pH sensor and / or a TDS sensor can be installed downstream of the first alkaline filter media 110 and the second alkaline filter media 120 in the first water path 141 and the second water path 142. In specific applications, a pH sensor and / or a TDS sensor can be installed in the outlet pipe 162 to obtain the pH value and TDS value of the outlet water.

[0098] The series-parallel switching water circuit includes a switching pipeline 143. One end of the switching pipeline 143 is connected between the downstream of the first alkaline filter material 110 and the first control valve 151, and the other end of the switching pipeline 143 is connected between the upstream of the second alkaline filter material 120 and the second control valve 152. The switching pipeline 143 is equipped with a switching control valve 153, which can control the flow rate or on / off state of the switching pipeline 143.

[0099] For example, in a high-flow-rate scenario, water can flow through the first alkaline filter material 110 and the second alkaline filter material 120 in sequence. The first control valve 151 and the switching control valve 153 can be opened, and the second control valve 152 can be closed. Water can flow through the first alkaline filter material 110 and the second alkaline filter material 120 in sequence.

[0100] For example, in low-flow scenarios, water can flow through the second alkaline filter material 120 alone. The first control valve 151 and the switching control valve 153 can be closed, and the second control valve 152 can be opened, allowing water to flow through the second alkaline filter material 120 alone.

[0101] For example, in some scenarios, water can flow through the first alkaline filter material 110 alone, and the second control valve 152 and the switching control valve 153 can be closed while the first control valve 151 is opened, allowing water to flow through the first alkaline filter material 110 alone.

[0102] Specifically, the water system includes an alkaline water path, one end of which is connected to the inlet pipe 161 and the other end of which is connected to the outlet pipe 162. The first alkaline filter material 110 and the second alkaline filter material 120 are connected to the alkaline water path. The water system also includes a non-alkaline water path, which is arranged in parallel with the alkaline water path. The two ends of the non-alkaline water path are respectively connected to the inlet pipe 161 and the outlet pipe 162.

[0103] Specifically, the first alkaline filter material 110 and the second alkaline filter material 120 are disposed in the same shell 200. Of course, in specific applications, the number of alkaline filter materials can be three or more, and the alkalinity of each filter material can vary in a gradient. Alternatively, the first alkaline filter material 110 and the second alkaline filter material 120 can be disposed in different shells 200, and the shells 200 can be connected in series through pipelines. Of course, a third alkaline filter material can also be provided, and the number of shells 200 can also be three or more.

[0104] The present invention also provides a mineral water purifier, including a housing, wherein the housing is provided with one of the above-mentioned filter elements;

[0105] Alternatively, the housing may be provided with one of the filter cartridges described above;

[0106] Alternatively, the housing may be provided with one of the aforementioned water systems.

[0107] Optionally, the mineral water purifier is equipped with a sensor component for acquiring the pH value of the effluent; the mineral water purifier is also equipped with a display component for displaying the pH value of the water. The sensor component can be a pH sensor. Alternatively, as an alternative to a pH sensor, TDS sensors can be installed upstream and downstream of the alkaline water path, respectively. The TDS sensor detects the conductivity of the water; the higher the TDS value, the more dissolved substances are present in the water. Generally, conductivity values ​​can be used to roughly understand the alkaline substances in the water; the higher the conductivity, the higher the alkalinity, and the higher the TDS value. A TDS sensor is an instrument that reflects the degree of water mineralization by measuring the conductivity of water. Conductivity is an indicator of ion concentration in water, reflecting the ability of dissolved substances in water to conduct electricity. Dissolved substances in water form ions, and these ions can conduct current when moving in water; therefore, conductivity can be used to assess the ion concentration in water. The higher the conductivity, the higher the ion concentration in the water, and the more dissolved substances may be present. During water treatment, conductivity can be used to monitor changes in water quality, and based on a preset data model, the pH value can be reflected by the TDS sensor. In practical applications, flow velocity sensors can be installed upstream and downstream of the alkaline water path. A first flow velocity sensor or flow meter is installed upstream of the alkaline filter media to detect the upstream water flow velocity. The first flow velocity represents the speed of the water flow before passing through the alkaline filter media (first alkaline filter media 110, second alkaline filter media 120). Similarly, a second flow velocity sensor or flow meter is installed downstream of the alkaline filter media to detect the downstream water flow velocity. The second flow velocity represents the speed of the water flow after passing through the alkaline filter media. When the water flow velocity increases, the scouring effect of the water flow on the TDS sensor may increase, resulting in a lower TDS sensor reading; conversely, when the water flow velocity decreases, the scouring effect of the water flow on the TDS sensor weakens, resulting in a higher TDS sensor reading. Therefore, after obtaining the first water flow velocity upstream and the second water flow velocity downstream of the alkaline filter media, a preset calibration model can be used to correct the first dissolved substance content value (TDS1) based on the first water flow velocity and the second dissolved substance content value (TDS2) based on the second water flow velocity. This eliminates the measurement error of the dissolved substance content values ​​upstream and downstream of the alkaline filter media caused by changes in water flow velocity, resulting in more accurate pH value acquisition. In specific applications, a flow meter can be installed upstream of the alkaline filter media (first alkaline filter media 110, second alkaline filter media 120) to obtain the cumulative flow through the first alkaline filter media 110 and the second alkaline filter media 120. Further correction can be performed using a preset calibration model combined with the TDS values ​​of the first alkaline filter media 110 and the second alkaline filter media 120.In practical applications, the lifespan of alkaline filter media can also be determined using a TDS sensor. In some embodiments, a TDS sensor is used to detect the content of downstream dissolved substances in the alkaline filter media. Based on a preset model, it can be determined whether the lifespan of the alkaline filter media has reached a preset replacement standard.

[0108] Optionally, the mineral water purifier has an alkaline water path that flows through the first alkaline filter material 110 and the second alkaline filter material 120. The mineral water purifier also has a non-alkaline water path. The alkaline water path and the non-alkaline water path are connected to a diversion control valve. A pH sensor can be installed at the outlet of the alkaline water path. When the pH value of the outlet water from the alkaline water path is high, the diversion control valve can be used to mix the water from the non-alkaline water path with the water from the alkaline water path so that the pH value of the outlet water is within a suitable range.

[0109] Optionally, the flow rates of the alkaline water path and the non-alkaline water path are controlled separately according to the set effluent pH value, so that the pH value of the effluent is the set effluent pH value. In specific applications, control valves can be installed in the alkaline water path and the non-alkaline water path respectively to control the flow rates of the alkaline water path and the non-alkaline water path. The non-alkaline water path can be a pure water path or an acidic water path. In specific applications, the non-alkaline water path can be connected to a metasilicic acid filter element or a pure carbon filter element, etc.

[0110] In practical applications, one, two, or more alkaline water paths can be configured. Two of the aforementioned filter cartridges can be connected in parallel, and the alkalinity of the filter media inside the two cartridges can differ. The flow rate can be adjusted by switching the water through the appropriate filter cartridge. For example, at a higher flow rate or when the pH value is set higher, the water can flow through the higher alkalinity filter cartridge. At a lower flow rate or when the pH value is set lower, the water can flow through the relatively lower alkalinity filter cartridge, and the flow ratio between the filter cartridges can be controlled. Of course, a pure water path can also be configured to control the final effluent pH value.

[0111] In this embodiment, the first alkaline filter material 110 contains a strongly alkaline mineralizing material, and the second alkaline filter material 120 contains a weakly alkaline mineralizing material. The strongly alkaline mineralizing materials include highly soluble minerals such as brucite, periclase, and sepiolite. When in water, these materials rapidly consume hydrogen ions and release hydroxide ions, thereby increasing the pH value of the water. Using a single strongly alkaline material typically leads to an initially excessively high pH (above 9). With prolonged use, the pH value gradually decreases to below 9. Towards the end of its lifespan, due to the consumption of the mineralizing material, the surface passivation of the minerals intensifies, and the pH value gradually decreases to 7 or even less than 7. The weakly alkaline mineralizing materials include less soluble minerals such as calcite, dolomite, and stalactite. When these materials react with water, they consume hydrogen ions more slowly, generating hydroxide ions through the hydrolysis of carbonate ions, thereby increasing the pH value of the water. When using a weakly alkaline material alone, the pH value is usually low in the early stages (below 7). As the usage time increases, the pH value gradually increases to above 7, and the service life is relatively long.

[0112] In the first alkaline filter media 110, taking brucite as an example, brucite contains Mg(OH)2, which allows brucite to undergo reaction A in water, thereby releasing (dissolving) OH. - This increases the pH value of the water.

[0113] Reaction A: Mg(OH)₂ = Mg 2+ +2OH -

[0114] In the second alkaline filter media 120, the weakly alkaline filter media 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 soaked in water, reaction B will first occur, releasing CO3 into the water. 2- Then CO3 2- It can undergo a hydrolysis reaction with H2O to produce OH. - .

[0115] Reaction B: CaCO3 = Ca 2+ +CO3 2-

[0116] Reaction C: CO3 2- +H2O HCO3 - +OH -

[0117] 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.

[0118] This invention provides a filter cartridge, its design, preparation method, filter element, water system, and mineralization water purifier. Utilizing the inhibition mechanism of strong alkaline materials on weak alkaline materials, a long-lasting alkaline filter cartridge is designed. In the early stages, the first alkaline filter material 110 (strong alkaline material) dissolves alkaline substances and inhibits the dissolution of alkaline substances by the second alkaline filter material 120 (weak alkaline material). In the middle and later stages, the inhibitory effect of the first alkaline filter material 110 on the second alkaline filter material 120 is alleviated. Both the first alkaline filter material 110 and the second alkaline filter material 120 dissolve alkaline substances in the middle and later stages, enabling long-term alkalization of the water. Within the overall lifespan of the filter cartridge, the pH value of the alkalized water can reach the design standard. The long filter cartridge lifespan eliminates the need for frequent replacements and provides standard-compliant alkaline water, meeting users' high-end drinking water needs and providing a superior user experience.
