For example, different implementation methods can be formed by combining different specific technical features / embodiments. In order to avoid unnecessary repetition, the various possible combinations of the various specific technical features / embodiments in this utility model will not be described separately.
[0028] This utility model provides a filter element, such as Figures 1 to 5As shown, the filter element includes a main body, which comprises at least an outer filter element 110 and an inner carbon fiber filter element 310. The outer filter element 110 and the inner carbon fiber filter element 310 are separately arranged, and the inner carbon fiber filter element 310 is cylindrical or columnar. The outer filter element 110 is disposed outside the inner carbon fiber filter element 310; the inner carbon fiber filter element 310 is disposed inside the outer filter element 110; the inner carbon fiber filter element 310 is a carbon fiber filter layer wound into a cylindrical or columnar shape. Even if the outer filter element 110 is a carbon rod, because the inner carbon fiber filter element 310 is disposed inside the outer filter element 110, the radial dimension of the carbon rod is relatively small, reducing flow resistance. Using a carbon fiber filter element inside the filter element also results in relatively low manufacturing costs. The carbon fiber filter element can be integrally formed with a mineralization layer, which has a better mineralization effect on the water flow and helps meet people's high-end demand for drinking water equipment that is beneficial to health.
[0029] Moreover, during production, the inner carbon fiber filter body 310 is formed by winding the carbon fiber filter layer 311. The number of winding layers of the inner carbon fiber filter body 310 can be controlled as needed. The number of winding layers of the inner carbon fiber filter body 310 can be flexibly adjusted according to different life design or usage requirements. There is no need to use or adjust molds, which helps to reduce the cost of the filter element and improves the flow performance of the filter element. The inner carbon fiber filter body 310 can be inserted into the inner cavity of the outer filter body 110, which is convenient for installation. The inner carbon fiber filter body 310, made of flexible material, does not deform under the impact of water flow.
[0030] Specifically, such as Figure 2 As shown, the raw material of the carbon fiber filter layer 311 can be in roll form, and a mineralization layer can be provided on the surface of the carbon fiber filter layer 311. The mineralization layer can be arranged in a layered structure on one or both sides of the carbon fiber filter layer. That is, the mineralization material (ore powder + binder) can be coated on the carbon fiber filter layer to form a mineralization layer.
[0031] In specific applications, the carbon fiber filter layer 311 has at least two mineralization layers along its length direction (i.e., the winding direction), and each of the mineralization layers is alternately arranged along the set direction of the carbon fiber filter layer 311, so that the water contains mineral components that are beneficial to human health, which helps to meet users' high-end demand for drinking water that is beneficial to health.
[0032] like Figure 3As shown, the two mineralized layers can be a first mineralized layer 321 and a second mineralized layer 322, respectively. The first mineralized layer 321 and the second mineralized layer 322 are arranged along the length direction (A direction) of the carbon fiber filter layer 311. When the wound carbon fiber filter layer 311 is fully unwound, a first mineralized layer 321 is arranged on one section along the length direction, and a second mineralized layer 322 is arranged on another section. The length ratio of the two sections can be set according to actual conditions, and the two mineralized layers can also be arranged alternately along the length direction. After the carbon fiber filter layer 311 is wound and formed, the inner carbon fiber filter body 310 is in a cylindrical or tubular shape. The first mineralized layer 321 and the second mineralized layer 322 are arranged in an inner-outer direction along the radial direction of the inner carbon fiber filter body 310, forming a wound structure of multiple layers of the first mineralized layer 321 (inner ring) and multiple layers of the second mineralized layer 322 (inner ring).
[0033] Alternatively, as shown in Figure 4 , the first mineralized layer 321 and the second mineralized layer 322 are arranged adjacent to each other along the width direction (B direction) of the carbon fiber filter layer 311. After the carbon fiber filter layer 311 is wound and formed, the inner carbon fiber filter body 310 is in a cylindrical or tubular shape. The first mineralized layer 321 and the second mineralized layer 322 are arranged in an up-down direction along the axial direction of the inner carbon fiber filter body 310.
[0034] Alternatively, the two surfaces of the carbon fiber filter layer 311 are respectively provided with the first mineralized layer 321 and the second mineralized layer 322, i.e., the carbon fiber layer is sandwiched between the first mineralized layer 321 and the second mineralized layer 322.
[0035] In this embodiment, the outer filter body 110 of the inner carbon fiber filter body 310 is arranged in an inner-outer direction, which is convenient to assemble. When producing, the number of layers of the inner carbon fiber filter body 310 wound can be flexibly set to match different design requirements. No mold is needed, and the mold does not need to be adjusted. The inner carbon fiber filter body 310 can be flexibly assembled as needed.
[0036] Specifically, the outer filter body 120 can be in a tubular shape, and the outer shape of the inner carbon fiber filter body 310 can match the shape of the inner cavity of the outer filter body 110. The two ends of the inner carbon fiber filter body 310 are aligned with the two ends of the outer filter body 110, forming a filter core body. The two ends of the filter core body are respectively provided with an upper end cover 221 and a lower end cover 222.
[0037] Specifically, the outer filter body 110 and the inner carbon fiber filter body 310 can be arranged in series. The water flow direction is as shown in Figure 1For example, in the direction of the arrow, the water flows through the outer filter 110 and the inner carbon fiber filter 310 in the radial direction. Alternatively, the filter core is arranged in the barrel shell 210. The barrel shell 210 is provided with a parallel water path structure for water to flow through the outer filter 110 and the inner carbon fiber filter 310, respectively. The outer filter 110 and the inner carbon fiber filter 310 can be separated by a central partition tube, which can be a plastic tube. The water cannot flow radially between the outer filter 110 and the inner carbon fiber filter 310, and the parallel water path structure can have two branch water paths and flow through the outer filter 110 and the inner carbon fiber filter 310 from the axial direction to meet the needs of different scenarios.
[0038] In a specific application, the first mineralization layer 321 and the second mineralization layer 322 can respectively dissolve different minerals, or the first mineralization layer 321 can dissolve zinc elements (the first mineralization layer 321 made of zinc-containing ore material, that is, the first mineralization layer 321 or the first mineralization layer 321 contains zinc), and the second mineralization layer 322 can be a weak alkaline filter material. When the water normally flows through the first mineralization layer 321 and the second mineralization layer 322, 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 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, by setting the second mineralization layer 322 as an alkaline filter material, the soaking water body can be weakly alkaline, thereby inhibiting the excessive dissolution of zinc elements in the first mineralization layer 321, 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 soaking in alkaline water to inhibit the dissolution of zinc elements, the zinc elements can be normally dissolved when the water flows (normal water flow), and the technical difficulty that the zinc-containing filter material easily leads to excessive zinc elements when soaked is overcome.
[0039] In some embodiments, the outer filter 110 and the inner carbon fiber filter 310 can respectively dissolve different minerals. For example, the outer filter 110 can dissolve zinc elements (the outer filter 110 is a zinc-containing filter), and the inner carbon fiber filter 310 can be a weak alkaline filter (i.e., the first mineralization layer 321 or / and the second mineralization layer 322 is an alkaline ore). When the water flows through the outer filter 110 and the inner carbon fiber filter 310 in turn, the zinc elements can be normally dissolved. Because the water in the filter core cannot be emptied when the water flow stops, the filter core is in a soaking state, and the remaining water in the barrel shell 210 is the soaking water body. When the filter core is in a soaking state, if the soaking water body is conventional pure water, the amount of zinc elements dissolved in a certain period of time will exceed the safety limit of the national standard, i.e., the zinc content of the soaking water body does not meet the drinking standard, which is not conducive to human health. In the present embodiment, by setting the inner carbon fiber filter 310 as an alkaline filter, the soaking water body can be weakly alkaline, thereby inhibiting the excessive dissolution of zinc elements in the outer filter 110, 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, and the mechanism of using alkaline water body soaking to inhibit the dissolution of zinc elements can make the zinc elements normally dissolved when the water flows (normal water flow), and overcome the technical difficulty that the zinc-containing filter easily leads to excessive zinc elements when soaked.
[0040] Specifically, as an optional combination scheme of the mineralization filter core, the inner carbon fiber filter 310 is a mineralization filter material that can dissolve minerals, and the outer filter 110 is a promoting filter material for promoting the mineralization filter material to dissolve minerals. The water path in the filter core can pass through the promoting filter material first and then pass through the mineralization filter material, so that the minerals in the mineralization filter material are promoted to be dissolved, and the mineral dissolution rate is faster, which can meet the needs of users when using water in a large flow. That is, under a large flow, the content of minerals can also reach the national standard or industry standard, and the situation that the content of mineralization is low due to insufficient dissolution of minerals is avoided. In specific applications, the promoting filter material can also be selectively connected in series upstream of the mineralization filter material.
[0041] In some embodiments, the outer filter 110 can be a carbon rod or carbon particle filter material, the first mineralization layer 321 can be a mineralization filter material that can dissolve minerals, and the second mineralization layer 322 can be a promoting filter material for promoting the mineralization filter material to dissolve minerals.
[0042] In specific applications, the water can flow through the outer filter 110 and the inner carbon fiber filter 310 in turn. The inner carbon fiber filter 310 is a calcium-containing or / and magnesium-containing mineralization filter material, and the outer filter 110 is an acidic filter material. The outer filter 110 includes a weak acid ore or is a weak acid ore, and the inner carbon fiber filter 310 includes a calcium-rich and magnesium-rich ore. The acidic substances dissolved by the outer filter 110 can promote the dissolution of calcium and magnesium elements of the inner carbon fiber filter 310.
[0043] In some embodiments, the first mineralization layer 321 can be an acidic filter material, and the second mineralization layer 322 can be a calcium-containing or magnesium-containing mineralization filter material. The acidic substance dissolved from the first mineralization layer 321 can promote the dissolution of calcium and magnesium elements from the second mineralization layer 322.
[0044] Alternatively, as an optional combination of the mineralization filter cartridge, the outer filter body 110 is a mineralization filter material that can dissolve mineral substances, and the inner carbon fiber filter body 310 is an anti-interference filter material that can inhibit the dissolution of mineral substances from the mineralization filter material, i.e., the inner carbon fiber filter body 310 can dissolve anti-interference substances that inhibit the dissolution of minerals from the outer filter body 110. In some scenarios, when the filter bodies in the filter cartridge are in a soaking state, the dissolution of certain mineral substances can exceed the set standard, and direct drinking is also not conducive to health. This combination scheme sets the anti-interference filter material to inhibit the dissolution of mineral substances in the mineralization filter material as needed, thereby preventing the content of mineral substances from exceeding the corresponding safety standard. The outer filter body 110 is a weak alkaline filter material, and the mineralization layer of the inner carbon fiber filter body 310 is a strong alkaline filter material; the strength of alkalinity between the weak alkaline filter material and the strong alkaline filter material can be a relative concept, i.e., the alkalinity of the inner carbon fiber filter body 310 is higher than that of the outer filter body 110. In specific applications, the strong alkaline filter material (made of strong alkaline material) such as brucite, which has a chemical composition of Mg(OH)2, can directly release (dissolve) OH - (reaction a: Mg(OH)2= Mg 2+ + 2OH - ) in water to increase the alkalinity of the water, while the weak alkaline filter material (made of weak alkaline material) such as calcite, which has a chemical composition of CaCO3, needs to release CO3 2- (reaction b: CaCO3= Ca 2+ + CO3 2- ) in water first, and then CO3 2- undergoes a hydrolysis reaction with H2O to generate OH - (reaction c: ). The strong alkaline material only needs one step to obtain OH - , while the weak alkaline material needs two steps to obtain OH - . Moreover, the rate of reaction c is much lower than that of reaction a, so the strong alkaline material preferentially releases OH - . When reaction a preferentially occurs, the chemical equilibrium of reaction c moves to the left, so the strong alkaline material can inhibit the release of OH - from the weak alkaline material. The inhibitory effect of the strong alkaline material on the weak alkaline material can be utilized to release OH - from the strong alkaline material in the early stage and release OH -, both of which can synergistically improve the service life of the filter element, thereby achieving long service life of the filter element.
[0045] In specific applications, as an optional combination scheme of the mineralized filter element, the outer filter body 110 is a first mineralized filter material that can dissolve a first mineral, and the inner carbon fiber filter body 310 is a second mineralized filter material that can dissolve a second mineral; the first mineralized filter material and the second mineralized filter material are used in combination to provide different minerals, and of course, a third mineralized filter body, a fourth mineralized filter body, and the like can be provided to form a filter element structure with more abundant minerals. In some embodiments, the first mineralization layer 321 can be a first mineralized filter material that can dissolve a first mineral, and the second mineralization layer 322 can be a second mineralized filter material that can dissolve a second mineral.
[0046] In specific applications, as an optional combination scheme of the mineralized filter element, the outer filter body 110 is a non-mineralized filter material, i.e., the outer filter body 110 can be a pure carbon rod or a ceramic filter body, etc., for adsorbing larger impurities and removing odors.
[0047] In specific applications, as an optional combination scheme of the mineralized filter element, the outer filter body 110 is an alkaline filter material (weakly alkaline), and the inner carbon fiber filter body 310 is a metasilicate filter material (the mineralization layer is made of metasilicate ore material). Metasilicic acid (H2SiO3) can be generated by hydrolysis of silicate ore in water. Taking sodium silicate (Na2SiO3) as an example, However, metasilicic acid and orthosilicic acid (H4SiO4) are in dynamic equilibrium. Orthosilicic acid has strong acidity and can exist stably in an acidic environment. Therefore, an alkaline environment moves the equilibrium of to the left, i.e., the content of orthosilicic acid decreases, and the concentration of metasilicic acid increases. However, too high alkalinity can 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 outer filter body 110 and the inner carbon fiber filter body 310 in sequence, the dissolution (dissolution) of metasilicic acid can be promoted, so that the content of metasilicic acid reaches a set standard.
[0048] In specific applications, the outer filter body 110 includes at least one of brucite and sepiolite; and the inner carbon fiber filter body 310 includes at least one of calcite and brucite.
[0049] Alternatively, the outer filter body 110 includes at least one of zincite and malachite; and the inner carbon fiber filter body 310 includes at least one of brucite, sepiolite, and calcite. It should be noted that in this embodiment, the particulate carbon can be used as a carrier for the minerals, i.e., the raw materials of the minerals and the particulate carbon are mixed and then sintered to form the particulate carbon.
[0050] Or, the outer filter 110 comprises at least one of hornblende, magnesium ore, dolomite; the inner carbon fiber filter 310 comprises at least one of brucite, sepiolite, calcite.
[0051] Or, the outer filter 110 comprises at least one of hornblende, magnesium ore, dolomite; the inner carbon fiber filter 310 comprises at least one of iron ore, silicate ore.
[0052] The embodiment also provides a design method of the filter element, for designing the filter element.
[0053] As the first design scheme, the outer filter 110 is designed to inhibit the dissolution of minerals in the inner carbon fiber filter 310, and specifically, the outer filter 110 is designed as a strong alkaline filter (carbon fiber is provided with a strong alkaline material layer), and the inner carbon fiber filter 310 is designed as a weak alkaline filter, and the weak alkaline filter is designed to release CO3 2- in water, and CO3 2- reacts reversibly with H2O to generate OH - . The strong alkaline filter can directly release (dissolve) OH - in water, and the strong alkaline material in the strong alkaline filter is taken as Mg(OH)2, reaction a: Mg(OH)2=Mg 2+ +2OH - , which increases the alkalinity of water, and the weak alkaline filter is taken as CaCO3, which needs to release CO3 2- in water first, reaction b: CaCO3=Ca 2+ +CO3 2- , and then CO3 2- reacts with H2O to generate OH - , reaction c: The strong alkaline filter only needs one step to obtain OH - , and the weak alkaline filter needs two steps to obtain OH - , and the rate of reaction c is much lower than that of reaction a, so the strong alkaline filter preferentially releases OH - . Reaction c is a reversible reaction, when reaction a preferentially occurs, the chemical equilibrium of reaction c moves to the left, so the strong alkaline filter can inhibit the release of OH - of the weak alkaline filter. The strong alkaline filter and the weak alkaline filter are assembled to form a split structure, and the strong alkaline filter and the weak alkaline filter can be assembled in the same filter shell, and the inhibition of the strong alkaline filter to the weak alkaline filter can be utilized, in the service life of the whole filter element, the strong alkaline material releases OH - in the early stage, and releases OH -, both can synergistically act, so that the life of the filter core is greatly improved, thereby realizing long life of the filter core.

The shell 210 is provided with filter cartridge water inlet and filter cartridge water outlet, and the filter cartridge water inlet is used for connecting the filter cartridge water inlet pipeline. The filter cartridge water outlet is used for connecting the filter cartridge water outlet pipeline. Figure 5
[0055] Specifically, the shell 210 can be provided with a series waterway structure for water to flow through the outer filter body 110 and the inner carbon fiber filter body 310 in sequence. In specific applications, the series waterway structure can enter the filter cartridge from the bottom of the shell 210, flow upward along the inner side of the filter cartridge, and then flow through the outer filter body 110 and the inner carbon fiber filter body 310 in sequence before flowing out from the filter cartridge water outlet to the filter cartridge water outlet pipeline. Of course, the series waterway structure can also flow through the outer filter body 110 and the inner carbon fiber filter body 310 in sequence.
[0056] The utility model further provides a mineral water purifier, the mineral water purifier includes above -mentioned filter core, or, the mineral water purifier includes above -mentioned filter cartridge.
[0057] In the embodiment, the inner carbon fiber filter body 310 includes a carbon fiber filter layer wound into a cylindrical shape. The carbon fiber filter layer has the inherent properties of carbon materials and also has the soft processability of textile fibers, making it easy to wind into the inner carbon fiber filter body 310 and install it inside the cylindrical outer filter body 110. The soft inner carbon fiber filter body 310 is protected and positioned by the outer filter body 110. More than 80% of the carbon atoms in the carbon fiber filter layer of the inner carbon fiber filter body 310 are located on the inner and outer surfaces, forming a unique adsorption and filtration structure known as a surface solid. Moreover, the inner carbon fiber filter body 310 is formed by setting a mineralized carbon fiber filter layer, which has both the function of dissolving mineral substances and the function of filtration. In addition, the carbon fiber filter layer wound into a cylindrical shape has a large flow area and small filtration resistance, fully dissolves mineral substances, and has good mineralization effect on water, which is beneficial to meet the high-end demand of people for drinking water equipment to meet the health needs.
