[0043] In specific applications, the mineralization of any two adjacent layers of the mineralized carbon fiber filter layer can be different. Of course, in some embodiments, the mineralization of some adjacent layers of the mineralized carbon fiber filter layer can be the same.
[0044] In specific applications, the carbon fiber filter body 100 can further include at least one non-mineralized carbon fiber filter layer 150 (pure carbon fiber filter layer), which can be used in combination with the first mineralized carbon fiber filter layer 151 or / and the second mineralized carbon fiber filter layer 152. As shown in FIG. 3(b), the first mineralized carbon fiber filter layer 151, the non-mineralized carbon fiber filter layer 150, the second mineralized carbon fiber filter layer 152, and the non-mineralized carbon fiber filter layer 150 are stacked and then wound.

As shown in FIG. 3(c), the non-mineralized carbon fiber filter layer 150 can be stacked between the first group combination and the second group combination. Alternatively, at least one non-mineralized carbon fiber filter layer 150 is provided in each group combination.
[0046] Alternatively, the mineralized carbon fiber filter layers are provided in multiple groups, each group of the mineralized carbon fiber filter layers including at least two mineralized carbon fiber filter layers with different mineralization, the mineralized carbon fiber filter layers in each group being alternately stacked, and the mineralization of the mineralized carbon fiber filter layers in at least two groups being different.
[0047] In specific applications, at least one non-mineralized carbon fiber filter layer 150 is provided between two adjacent groups of the mineralized carbon fiber filter layers;
[0048] In specific applications, each group of the mineralized carbon fiber filter layers can include at least one non-mineralized carbon fiber filter layer 150; as shown in FIG. 3(d), the first mineralized carbon fiber filter layer 151, the non-mineralized carbon fiber filter layer 150, the second mineralized carbon fiber filter layer 152, the non-mineralized carbon fiber filter layer 150, the third mineralized carbon fiber filter layer 153, and the non-mineralized carbon fiber filter layer 150 are sequentially stacked and then wound, which can effectively remove odors, impurities, and the like, and is conducive to further improving the taste of drinking water.
[0049] In specific applications, the mineralized carbon fiber filter layers and the non-mineralized carbon fiber filter layer 150 can be alternately arranged to meet different use scenario requirements.
[0050] In a specific application, the mineralized carbon fiber filter layers can be sequentially arranged along the length direction as the first mineralized carbon fiber filter layer 151, the second mineralized carbon fiber filter layer 152, and the third mineralized carbon fiber filter layer 153 (or the non-mineralized carbon fiber filter layer 150), which are wound to form the carbon fiber filter body 100. As shown in Figure 4 the outer ring area 113 is the first mineralized carbon fiber filter layer 151, the middle ring area 112 is the second mineralized carbon fiber filter layer 152, and the inner ring area 111 is the third mineralized carbon fiber filter layer 153 (or the non-mineralized carbon fiber filter layer 150).
[0051] For example, in the first embodiment, the first mineralized carbon fiber filter layer 151, the non-mineralized carbon fiber filter layer 150, the second mineralized carbon fiber filter layer 152, and the non-mineralized carbon fiber filter layer 150 are sequentially stacked, and then wound as a combined stack.
[0052] In the second embodiment, one or at least two layers of the first mineralized carbon fiber filter layer 151, one or at least two layers of the non-mineralized carbon fiber filter layer 150, and one or at least two layers of the second mineralized carbon fiber filter layer 152 are sequentially stacked, and then wound as a combined stack.
[0053] For example, in the first embodiment, the third mineralized carbon fiber filter layer 153 is also provided, and the first mineralized carbon fiber filter layer 151, the non-mineralized carbon fiber filter layer 150, the second mineralized carbon fiber filter layer 152, the non-mineralized carbon fiber filter layer 150, the third mineralized carbon fiber filter layer 153, and the non-mineralized carbon fiber filter layer 150 are sequentially stacked, and then wound as a combined stack.
[0054] Specifically, as shown in Figure 5 the mineralized carbon fiber filter body 100 is wound to form a first mineralized filter body, and the filter core can also include a second filter body 120, which is a mineralized filter body. The second filter body 120 can be in a cylindrical shape, and the mineralized carbon fiber filter layers can be wound outside the second filter body 120 to form the first mineralized filter body, so that the water contains mineral components beneficial to human health, which is conducive to meeting the high-end demand of users for drinking water that meets the beneficial health requirements.
[0055] In a specific application, the mineralized filter core can be used in cooperation with a conventional filter core (such as an RO membrane filter core), i.e., the mineralized filter core can be arranged downstream of the filter core, and the pure water formed by the filter core passes through the mineralized filter core. The mineralized filter core can dissolve an appropriate amount of minerals in the water, so that the drinking water provided to the user has an appropriate amount of minerals, which is beneficial to the health of the user.
[0056] The first mineralization filter and the second mineralization filter can respectively dissolve different minerals, or the first mineralization filter can dissolve zinc elements (the first mineralization filter is a zinc-containing filter), and the second mineralization filter can be a weak alkaline filter. When the water flow normally flows through the first mineralization filter and the second mineralization filter, the zinc elements can be normally dissolved. Since the water in the filter core cannot be emptied when the water flow stops, the filter core is inevitably in a soaking state. The remaining water in the filter core is the soaking water body. When the filter core is in a soaking state, if the soaking water body is conventional pure water (water filtered by an RO membrane), the amount of zinc elements dissolved in a certain period of time will exceed the safety limit value of the national standard, that is, the zinc content of the soaking water body does not meet the drinking standard, which is not conducive to human health. In the embodiment, the second mineralization filter is set as an alkaline filter, so that the soaking water body is weakly alkaline, thereby inhibiting the excessive dissolution of zinc elements in the first mineralization filter, and the zinc concentration in the soaking water body also meets the national standard. The zinc elements in the water body can be prevented from exceeding the set range under the soaking condition. By using the mechanism of inhibiting the dissolution of zinc elements by alkaline water soaking, the zinc elements can be normally dissolved when the water flow (normal water flow), and the technical difficulty that the zinc elements in the zinc-containing filter are prone to exceed the standard when soaked is overcome.
[0057] Specifically, as the first optional combination scheme of the mineralization filter core, the second mineralization filter is a mineralization filter material that can dissolve minerals, and the first mineralization filter is a promoting filter material for promoting the dissolution of minerals by the mineralization filter material. The water path in the filter core can first pass through the promoting filter material and then pass through the mineralization filter material, so that the minerals in the mineralization filter material are promoted to dissolve, and the dissolution rate of the minerals is relatively fast, which can meet the demand of the user for large-flow water. That is, under a large flow, the content of the minerals can also meet the national standard or the industry standard, and the situation that the content of the mineralization substance is low due to insufficient dissolution of the minerals is avoided. In specific applications, the promoting filter material can also be selectively connected in series upstream of the mineralization filter material. Of course, the first mineralization filter and the second mineralization filter connected in an inner-outer split manner can be arranged in the same cavity. The water path can pass through the first mineralization filter and the second mineralization filter in sequence, or the water path can pass through the second mineralization filter and the first mineralization filter respectively (that is, the filters are connected in parallel), so as to meet different use requirements.
[0058] In specific applications, the water flow can flow through the first mineralization filter and the second mineralization filter in sequence. The second mineralization filter is a calcium-containing or magnesium-containing mineralization filter material, and the first mineralization filter is an acidic filter material. The first mineralization filter includes a weakly acidic ore or is a weakly acidic ore, and the second mineralization filter includes an ore filled with calcium and magnesium. The acidic substances dissolved by the first mineralization filter can promote the dissolution of calcium and magnesium elements of the second mineralization filter.
[0059] Alternatively, as a second optional combination of mineralizing filter elements, the first mineralizing filter element is a mineralizing filter material that can dissolve minerals, and the second mineralizing filter element is an anti-antagonistic filter material that can inhibit the dissolution of minerals from the mineralizing filter material. That is, the second mineralizing filter element can dissolve an anti-antagonistic substance used to inhibit the dissolution of minerals in the first mineralizing filter element. In some scenarios, when the filter material inside the filter element is in a soaking state, the dissolution of certain minerals may exceed the set standard, which is detrimental to health if consumed directly. This combination solution, by setting an anti-antagonistic filter material, allows the anti-antagonistic filter material to inhibit the dissolution of minerals from the mineralizing filter material where necessary, thereby preventing the mineral content from exceeding the corresponding safety standards. In specific applications, the first mineralizing filter element is a weakly alkaline filter material, and the second mineralizing filter element is a strongly 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 second mineralizing filter element is higher than that of the first mineralizing filter element. In specific applications, strongly alkaline filter media (made of strongly alkaline materials), such as brucite, with the chemical composition Mg(OH)2, can directly release (dissolve) OH- in water. - (Reaction a: Mg(OH)2=Mg) 2+ +2OH - This increases the alkalinity of the water, while weakly alkaline filter media (made of weakly alkaline materials), such as calcite, whose chemical composition is CaCO3, need to release CO3 into the water first. 2- (Reaction b: CaCO3 = Ca) 2+ +CO3 2- ), then CO3 2- It undergoes a hydrolysis reaction with H2O to produce OH- - (Reaction c: CO3) 2- +H2O HCO3 - +OH - Strongly alkaline materials can produce OH- in just one reaction step. - Weakly basic materials require two steps of reaction to obtain OH. - Furthermore, the rate of reaction c is much lower than the rate of reaction a, therefore the strongly alkaline material preferentially releases OH-. - Reaction c is a reversible reaction. When reaction a occurs preferentially, the chemical equilibrium of reaction c shifts to the left. Therefore, strongly basic materials can suppress the OH- of weakly basic materials. - Release. In this combination, strong alkaline materials and weak alkaline materials are combined and assembled to form an inner and outer separate structure. Strong and weak alkaline materials can be assembled within the same filter element. The inhibitory effect of the strong alkaline material on the weak alkaline material can be utilized. Throughout the filter element's service life, the strong alkaline material releases OH- in the early stages. - In the middle and later stages, it releases OH- along with weakly alkaline materials. -, both can synergistically work, so that the life of the filter core can be greatly improved, thereby realizing the long life of the filter core. In specific applications, the strong alkaline filter body and the weak alkaline filter body can be provided with one, two or more, of course, they can also be combined with medium alkaline materials, that is, two or more alkaline filter bodies are arranged along the radial direction of the filter core, for example, a first alkaline filter body, a second alkaline filter body and a third alkaline filter body are arranged along the radial direction from outside to inside, the alkalinity of the first alkaline filter body is greater than that of the second alkaline filter body, and the alkalinity of the second alkaline filter body is greater than that of the third alkaline filter body. Alternatively, in specific applications, the first mineralized filter body is a zinc mineralized filter material or a copper mineralized filter material, that is, the first mineralized filter body is a zinc-containing or / and copper-containing mineralized filter material, and the second mineralized filter body is an alkaline filter material; the alkaline substances dissolved from the second mineralized filter body (alkaline filter material) can inhibit the dissolution of zinc and copper elements in the first mineralized filter body. Specifically, the dissolution reaction of zinc element (zinc-containing filter body, such as zincite) in water is: ZnCO3=Zn 2+ +CO3 2- ; under general conditions (pure water obtained after RO membrane filtration), Zn 2+ has a saturation solubility of up to 6.0 mg / L, which is much higher than the limit value of 1.0 mg / L in the national standard; when the water quality remains unchanged, Zn 2+ and CO3 2- are dissolved synchronously, and by controlling the concentration of CO3 2- at the lowest level, the saturation dissolution concentration of Zn 2+ can be controlled at the lowest level; according to the equilibrium diagram of H2CO3-HCO3 - -CO3 2- in water, when the pH value is about 8.3, the concentration of CO3 2- is at the lowest level, and at this time, the concentration of Zn 2+ in the soaking water is also at the lowest level, which is theoretically calculated as 0.36 mg / L, meeting the standard limit value; that is, by adjusting the pH value of the water soaked in the zinc-containing filter body to about 8.3, the concentration of Zn 2+ can be accurately controlled between 0.2-1.0 mg / L.
[0060] In specific applications, as a third optional combination scheme of the mineralized filter core, the first mineralized filter body is a first mineralized filter material capable of dissolving a first mineral substance, and the second mineralized filter body is a second mineralized filter material capable of dissolving a second mineral substance; the first mineralized filter material and the second mineralized filter material are used in combination to provide different mineralized substances, of course, third mineralized filter bodies, fourth mineralized filter bodies, etc. can also be provided to form a filter core structure with more abundant mineralized substances. In this combination, a filter core with abundant mineralized substances can be formed, and through the combination and matching of various filter bodies, the high-end demand of users for healthy drinking water can be better met.
[0061] In specific applications, as the fourth alternative combination scheme of the mineralization filter element, the first mineralization filter is an alkaline filter material (weakly alkaline), and the second mineralization filter is a metasilicate filter material. Metasilicic acid (H2SiO3) can be generated by the hydrolysis reaction of silicate ore in water. For example, sodium silicate (Na2SiO3) is taken as an example, SiO3 2- + H2O H2SiO3 + 2OH - , H2SiO3 + H2O H4SiO4, but metasilicic acid and orthosilicic acid (H4SiO4) are in dynamic equilibrium. Orthosilicic acid has strong acidity and can exist stably in an acidic environment. Therefore, the alkaline environment moves the equilibrium of H2SiO3 + H2O H4SiO4 to the left, that is, the content of orthosilicic acid decreases, and the concentration of metasilicic acid increases. However, too high alkalinity will inhibit the hydrolysis of silicate ions, thereby reducing the generation of metasilicic acid. Therefore, appropriate alkalinity can promote the formation of metasilicic acid. In specific applications, by making the water flow through the first mineralization filter and the second mineralization filter in sequence, the dissolution of metasilicic acid can be promoted, so that the content of metasilicic acid reaches the set standard.
[0062] In specific applications, the first mineralization filter includes at least one of brucite and sepiolite; and the second mineralization filter includes at least one of calcite and brucite.
[0063] Alternatively, the first mineralization filter includes at least one of smithsonite and malachite; and the second mineralization filter includes at least one of brucite, sepiolite, and calcite.
[0064] Alternatively, the first mineralization filter includes at least one of hornblende, magnesite, and dolomite; and the second mineralization filter includes at least one of brucite, sepiolite, and calcite.
[0065] Alternatively, the first mineralization filter includes at least one of hornblende, magnesite, and dolomite; and the second mineralization filter includes at least one of iron ore and silicate ore.
[0066] Specifically, the first mineralization filter can be in a cylindrical shape, and the second mineralization filter can be in a cylindrical shape or a columnar shape. The second mineralization filter can be in a cylindrical shape, a polygonal columnar shape, a circular truncated cone shape, or the like.
[0067] Specifically, the second filter 120 has a base material, which can be a carbon rod filter element, a ceramic filter element, or a carbon fiber. The mineralization filter material, the promotion filter material, the anti-oxidation filter material, or the neutralization filter material is dispersed in the base material or attached to the surface of the base material.
[0068] This embodiment also provides a filter element design method for designing the aforementioned filter element. As a first design scheme, the first mineralization filter element is designed to inhibit the leaching of minerals from the second mineralization filter element. Specifically, the first mineralization filter element can be designed as a strongly alkaline filter element, and the second mineralization filter element can be designed as a weakly alkaline filter element. The weakly alkaline filter element is designed to release CO3 into the water. 2- , using CO3 2- It undergoes a reversible hydrolysis reaction with H2O to produce OH- - Strongly alkaline filter media can directly release (dissolve) OH- in water. - Taking Mg(OH)2 as an example, the strongly alkaline material in a strongly alkaline filter is reacted as follows: Mg(OH)2 = Mg 2+ +2OH - This increases the alkalinity of the water, while weakly alkaline filters, such as those using CaCO3, require the release of CO3 into the water first. 2- Reaction b: CaCO3 = Ca 2+ +CO3 2- Then CO3 2- It undergoes a hydrolysis reaction with H2O to produce OH- - Reaction c: CO3 2- +H2O HCO3 - +OH - Strongly alkaline filters require only one reaction step to obtain OH-. - A weakly alkaline filter requires two steps to obtain OH-. - Furthermore, the rate of reaction c is much lower than the rate of reaction a, therefore the strongly alkaline filter preferentially releases OH-. - Reaction c is a reversible reaction. When reaction a occurs preferentially, the chemical equilibrium of reaction c shifts to the left. Therefore, a strongly basic filter can inhibit the OH- of a weakly basic filter. - Release. Strongly alkaline and weakly alkaline filter elements are assembled into a separate structure. The strongly alkaline and weakly alkaline filter elements can be assembled within the same filter housing. The inhibitory effect of the strongly alkaline filter element on the weakly alkaline filter element can be utilized. During the entire service life of the filter element, the strongly alkaline material releases OH- in the early stages. - In the middle and later stages, it releases OH- along with weakly alkaline materials. - The two can work together to greatly extend the lifespan of the filter element, thus achieving a longer filter element lifespan.
[0069] This utility model embodiment also provides a filter cartridge, such as Figures 1 to 6 As shown, the system includes a housing 210 and the aforementioned filter element, which is disposed within the housing 210. The housing 210 is provided with a filter element inlet and a filter element outlet. The filter element inlet is used to connect to the filter element inlet pipe.
