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. Mineralized water, containing mineral salts and rich in essential macro- and micro-elements, is favored as drinking water. Furthermore, there is a demand for mineralized water containing specific mineral salts during production and experimentation. Zinc-mineralized water, in particular, is crucial, as zinc is the second most abundant trace element in the human body after iron, playing a vital role. It is present in over 200 enzymes, participating in the synthesis of nucleic acids, proteins, and carbohydrates, as well as the absorption and utilization of vitamin A. Zinc is indispensable for cell replication, immune activity, tissue repair, and growth, and is a key element in growth and development, reproductive heredity, the immune system, and bone metabolism. Zinc-mineralized water is a direct and efficient way to supplement zinc, as the zinc in it exists in ionic form, making it more easily absorbed by the body.

[0003] Currently, there are two common methods for preparing zinc mineral water. The first method involves artificially mixing zinc mineral salts with water to create zinc mineral water of suitable concentration. However, this method is cumbersome, requires a certain level of chemical knowledge, and is relatively inefficient. The second method involves adding ore containing zinc mineral salts to a container filled with water—such as a water dispenser or water purifier. The zinc mineral salts in the ore dissolve into the water in the container, transforming it into zinc mineral water. However, it is difficult to effectively control the zinc content in zinc mineral water prepared using this method. When the zinc content is insufficient, the zinc mineral water cannot meet the user's needs; when the zinc content exceeds the standard, it will have adverse effects. Utility Model Content

[0004] In view of this, this application provides a filter element assembly and a mineral water purifier, which can reduce the probability of excessive zinc content in zinc-mineralized water.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application is: to provide a filter element assembly, including a zinc-containing filter body, a combined filter body and an alkaline filter body, wherein the combined filter body includes a first zinc-containing block and a second alkaline block, and the filter element assembly is provided with an internal water channel, wherein the zinc-containing filter body, the combined filter body and the alkaline filter body are arranged in parallel in the internal water channel.

[0006] In one specific embodiment, the filter element assembly includes a filter cartridge, which is vertically arranged and has a cavity inside. At least part of the internal water passage is arranged in the cavity, and the zinc-containing filter body, the combined filter body, and the alkaline filter body are arranged sequentially from top to bottom in the cavity.

[0007] In one specific embodiment, the internal water passage has an inlet and an outlet. The fluid entering the internal water passage through the inlet flows successively through the first zinc-containing block and the second alkaline block, and then flows out from the outlet; or, the fluid entering the internal water passage through the inlet simultaneously flows through the first zinc-containing block and the second alkaline block, and then flows out from the outlet.

[0008] In one specific embodiment, the water inlet and the water outlet are disposed on the filter cartridge, the internal water path further includes a central water outlet channel, the central water outlet channel is disposed along the axial direction of the filter cartridge and passes through the zinc-containing filter body, the combined filter body and the alkaline filter body, the filter element assembly further includes an end cap, the end cap blocks one end of the central water outlet channel, and the other end of the central water outlet channel is connected to the water outlet.

[0009] In one specific embodiment, the first zinc-containing block is disposed on the outer periphery of the second alkaline block, and the second alkaline block is disposed between the central water outlet channel and the first zinc-containing block.

[0010] In one specific embodiment, the first zinc-containing block and the second alkaline block are arranged opposite to each other, and the first zinc-containing block and the second alkaline block surround each other to form a portion of the central water outlet channel between the first zinc-containing block and the second alkaline block.

[0011] In one specific embodiment, the first zinc-containing block is connected to the zinc-containing filter body, and the second alkaline block is connected to the alkaline filter body.

[0012] In one specific embodiment, the internal water circuit includes a first internal water circuit, a second internal water circuit, and a third internal water circuit that are connected in parallel and isolated from each other. The zinc-containing filter is disposed in the first internal water circuit, the combined filter is disposed in the second internal water circuit, and the alkaline filter is disposed in the third internal water circuit.

[0013] To solve the above-mentioned technical problems, another technical solution adopted in this application is to provide a mineral water purifier, including a main body of the device and a filter element assembly as described in any of the above specific embodiments, wherein the main body of the device is connected to the filter element assembly.

[0014] In one specific embodiment, the main body of the device is provided with a first water inlet, a second water inlet, a third water inlet, and a water outlet. The main body of the device includes a first valve body, a second valve body, and a third valve body. The first valve body is connected to the first water inlet, the second valve body is connected to the second water inlet, and the third valve body is connected to the third water inlet. The filter element assembly is provided with a first internal water channel, a second internal water channel, and a third internal water channel that are connected in parallel and isolated from each other. The filter element assembly includes a zinc-containing filter element, a combined filter element, and an alkaline filter element. The zinc-containing filter element is disposed in the first internal water channel, the combined filter element is disposed in the second internal water channel, and the alkaline filter element is disposed in the third internal water channel. One end of the first water inlet is connected to the first internal water channel, one end of the second water inlet is connected to the second internal water channel, and one end of the third water inlet is connected to the third internal water channel. The other ends of the first water inlet, the second water inlet, and the third water inlet, which are away from the filter element assembly, are all connected to the water outlet.

[0015] The beneficial effects of this application include: the zinc-containing filter, the combined filter, and the alkaline filter are arranged in parallel. When the filter assembly continuously discharges water, the zinc element in the first zinc-containing block of the combined filter and the alkaline substance in the second alkaline block dissolve normally into the flowing water. At this time, the alkaline substance does not affect the dissolution of zinc. Furthermore, because the flowing water stays at the zinc-containing filter and the first zinc-containing block for a short time, the risk of excessive zinc content in the flowing water is low. However, when the filter assembly stops discharging water, the soaking water no longer flows through the zinc-containing filter, the combined filter, and the alkaline filter. The first zinc-containing block and the second alkaline block are simultaneously soaked in the water, allowing the alkaline substance to act on the first zinc-containing block. Although there is sufficient contact time between the soaking water and the first zinc-containing block during soaking, the alkaline substance can inhibit the excessive dissolution of zinc into the water during soaking, thereby controlling the zinc content in the water and reducing the impact of soaking on the service life of the mineralized filter media. The filter element assembly structure provided in this application can effectively control the zinc content in mineralized water, whether in a flow or immersion state. Furthermore, the parallel arrangement of zinc-containing filter elements, combined filter elements, and alkaline filter elements can also be used to output three different types of water to the filter element assembly, thereby improving the stability and usability of the filter element assembly.

[0033] With increased productivity, people's demands for quality of life and convenience are also rising. Mineralized water, containing mineral salts and rich in essential macro- and micro-elements, is favored as drinking water. Furthermore, there is a demand for mineralized water containing specific mineral salts during production and experimentation. Zinc-mineralized water, in particular, is crucial, as zinc is the second most abundant trace element in the human body after iron, playing a vital role. It is present in over 200 enzymes, participating in the synthesis of nucleic acids, proteins, and carbohydrates, as well as the absorption and utilization of vitamin A.

Zinc-mineralized water is a direct and efficient way to supplement zinc, as the zinc in it exists in ionic form, making it more easily absorbed by the body.

[0034] Currently, there are two common methods for preparing zinc mineral water. The first method involves artificially mixing zinc mineral salts with water to create zinc mineral water of suitable concentration. However, this method is cumbersome, requires a certain level of chemical knowledge, and is relatively inefficient. The second method involves adding ore containing zinc mineral salts to a container filled with water—such as a water dispenser or water purifier.

When the zinc content is insufficient, the zinc mineral water cannot meet the user's needs; when the zinc content exceeds the standard, it will have adverse effects.

[0035] 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.

[0036] See Figures 1 to 7 , Figure 1 This is a schematic diagram of the assembly structure of the filter element assembly 1 provided in this application. Figure 2 This is a cross-sectional structural schematic diagram of an embodiment of the filter element assembly 1 provided in this application. Figure 3 for Figure 2 A schematic diagram showing the exploded structure of the zinc-containing filter element 2, the combined filter element 3, and the alkaline filter element 4 in the middle filter element assembly 1. Figure 4 This is a cross-sectional structural schematic diagram of another embodiment of the filter element assembly 1 provided in this application. Figure 5 for Figure 4 A schematic diagram showing the exploded structure of the zinc-containing filter element 2, the combined filter element 3, and the alkaline filter element 4 in the middle filter element assembly 1. Figure 6 This is a cross-sectional structural schematic diagram of another embodiment of the filter element assembly 1 provided in this application. Figure 7 for Figure 6 A schematic diagram showing the exploded structure of the zinc-containing filter element 2, the combined filter element 3, and the alkaline filter element 4 in the middle filter element assembly 1.

[0037] This application provides a filter element assembly 1 for treating fluids. The filter element assembly 1 may include a zinc-containing filter element 2, a combined filter element 3, and an alkaline filter element 4. The combined filter element 3 includes a first zinc-containing block 31 and a second alkaline block 32. The filter element assembly 1 has an internal water passage 11, in which the zinc-containing filter element 2, the combined filter element 3, and the alkaline filter element 4 are arranged in parallel.

[0038] The alkaline filter body 4 and the second alkaline block 32 can both include alkaline filter media 6, which contains alkaline substances that can dissolve into the water. The zinc-containing filter body 2 and the first zinc-containing block 31 can both include zinc-containing filter media 5, which contains zinc elements that can enter the water, such as soluble zinc salts.

[0039] In the structure provided in this specific embodiment, the zinc-containing filter body 2, the combined filter body 3, and the alkaline filter body 4 are arranged in parallel. Under the condition that the filter element assembly 1 continuously discharges water, the zinc element in the first zinc-containing block 31 and the alkaline substance in the second alkaline block 32 in the combined filter body 3 normally dissolve into the water. At this time, the alkaline substance does not affect the dissolution of zinc element. Moreover, since the water stays at the zinc-containing filter body 2 and the first zinc-containing block 31 for a short time, the risk of the zinc element content in the water exceeding the standard is low.

[0040] When the filter element assembly 1 stops immersing water, the immersion water no longer flows through the zinc-containing filter body 2, the combined filter body 3, and the alkaline filter body 4. The first zinc-containing block 31 and the second alkaline block 32 are simultaneously immersed in the water, allowing the alkaline substances to act on the first zinc-containing block 31. Although the immersion water and the first zinc-containing block 31 have sufficient contact time in the immersion state, the alkaline substances can inhibit the large-scale dissolution of zinc elements into the water during immersion, thereby controlling the zinc content in the water and reducing the impact of the immersion state on the service life of the mineralized filter material.

[0041] The filter element assembly 1 structure provided in this application can effectively control the zinc content in mineralized water, whether in the flow state or the soaking state. Furthermore, the zinc-containing filter body 2, the combined filter body 3, and the alkaline filter body 4 arranged in parallel can also be used to output three different types of water to the filter element assembly 1, thereby improving the stability and usability of the filter element assembly 1.

[0042] Optionally, the alkaline filter 4 and the second alkaline block 32 may include at least one of the following materials: calcite, aragonite, magnesite, dolomite, etc. The zinc-containing filter 2 and the first zinc-containing block 31 may include at least one of the following materials: smithsonite, calamine, zinc ore, etc. The alkaline substances dissolved from the alkaline filter 4 and the second alkaline block 32 can inhibit the dissolution of zinc from the zinc-containing filter 2 and the first zinc-containing block 31.

[0043] Specifically, the dissolution reaction of zinc (containing zinc filter material 2, such as smithsonite) in water is: ZnCO3 = Zn 2+ +CO3 2- Under normal conditions (e.g., pure water obtained after RO membrane filtration), Zn 2+ The saturated solubility of Zn in water can reach 6.0 mg / L, far exceeding the national standard limit of 1.0 mg / L. Furthermore, under constant water quality conditions, Zn... 2+ and CO3 2- It is dissolved simultaneously. Therefore, CO3 2- By controlling the concentration of Zn to the lowest possible level, 2+ The saturated dissolution concentration is controlled at the lowest level.

[0044] like Figure 9 As shown, Figure 9 It is H2CO3-HCO 3- -CO3 2- Equilibrium diagram in water. When the pH of the water is acidic, due to the presence of H+ in the system... + Excessive plasma inhibits the continued release of H2CO3 through hydrolysis. + As the pH value of the water gradually increases, the H in the system... + As plasma gradually decreases, the inhibitory effect on H2CO3 hydrolysis gradually decreases, and H... + As ions are gradually released through hydrolysis, H2CO3 in the water is first converted into HCO3-. 3- As the pH value of the water continues to rise, HCO3- 3- H in + Ions also continued to be released, HCO3- 3- Gradually converted into CO3 2- It is not difficult to see that CO3 2- Its content in water is clearly correlated with the pH value of the water.

[0045] When the pH value is (approximately) 8.3, CO3 2- The concentration of Zn is at its lowest level, at which point the concentration of Zn is at its lowest. 2+ The concentration of Zn in the soaking water was also at the lowest level, theoretically calculated to be 0.36 mg / L, which meets the standard limit. That is, by adjusting the pH of the water soaked in the zinc-containing filter 2 to around 8.3, the Zn concentration can be reduced. 2+ The concentration is precisely controlled between 0.2-1.0 mg / L.

[0046] The following example illustrates the effect of different alkaline water pH values ​​on the zinc concentration in the soaking water. A modified smithsonite with a pore-forming agent ratio of 2% and a co-solvent ratio of 1.0% was selected. The instantaneous zinc concentration in the effluent after a 1000L flow and the zinc concentration in the soaking water after 12 hours of soaking were recorded, as shown in Table 1.

[0047] Table 1

[0048] pH value of soaking water Zinc concentration in flowing water (mg / L) Zinc concentration in immersion water (mg / L) 6.0 0.96 5.74 7.2 0.77 1.15 8.0 0.52 0.46 8.3 0.5 0.38 8.5 0.48 0.35 9.0 0.17 0.10

[0049] Referring to Table 1, when no alkaline substances are added, the pH of the soaking water is 6, which is weakly acidic. At this pH, zinc leaching from both the flowing water and the soaking water is not inhibited, resulting in a high zinc concentration in the soaking water, exceeding the standard limit. Even when the pH of the soaking water is 7.2, the zinc concentration still exceeds the standard. When the pH of the soaking water is between 8.0 and 8.5, CO3... 2 The concentration of Zn is at its lowest level. 2+ The concentration of zinc in the soaking water was also at the minimum level, between 0.2 and 1.0 mg / L, which meets the standard. When the pH of the soaking water was 9.0, the alkalinity of the alkaline substance was relatively strong, and the zinc dissolution was excessively inhibited during overflow. The zinc concentration in both the overflow and soaking water was below 0.2 mg / L, which does not meet the standard.

[0050] Optionally, the mineralizing filter media can be used to adjust the pH value of the water, while the antagonistic filter media is used to neutralize the pH value of the water. The minerals dissolved from the mineralizing filter media can raise the pH value of the water. In practical applications, the pH value of the water can be adjusted by these minerals. The antagonistic filter media can be used to neutralize the minerals to control the pH value of the water, so that the overall pH value of the effluent can be stabilized within the set pH range (generally 7.0 to 9.0).

[0051] In one specific embodiment of this application, the filter element assembly 1 includes a filter cartridge 12, which is vertically arranged and has a cavity 121 inside. At least part of the internal water passage 11 is arranged in the cavity 121, and the zinc-containing filter body 2, the combined filter body 3, and the alkaline filter body 4 are arranged in the cavity 121 from top to bottom.

[0052] In the structure provided in this specific embodiment, the zinc-containing filter body 2, the combined filter body 3, and the alkaline filter body 4 are vertically layered in the cavity 121. During flow, the water in the uppermost layer of the cavity 121 is filtered by the zinc-containing filter body 2, the water in the middle layer is filtered by the combined filter body 3, and the water in the lowermost layer is filtered by the alkaline filter body 4. The water filtered by different filter bodies contains different types and amounts of substances, thus enabling the parallel arrangement of the zinc-containing filter body 2, the combined filter body 3, and the alkaline filter body 4. During immersion, the cavity 121 is filled with water. The alkaline substances released by the alkaline filter body 4 and the second alkaline block 32 can inhibit the dissolution of zinc from the zinc-containing filter body 2 and the first zinc-containing block 31, thereby controlling the zinc content in the water and reducing the impact of immersion on the service life of the mineralized filter media.

[0053] Furthermore, multiple water outlets are provided at different levels of the cavity 121, enabling the output of water with different compositions to the outside under flow conditions. Valves can even be installed at different water outlets to control the blending of water with different compositions, obtaining water with pH values ​​and compositions that meet water usage requirements, such as alkaline water or zinc-mineralized water.

[0054] In one specific embodiment of this application, the internal water passage 11 has an inlet 111 and an outlet 112. The fluid entering the internal water passage 11 through the inlet 111 flows through the first zinc-containing block 31 and the second alkaline block 32, and then flows out from the outlet 112.

[0055] In the structure provided in this specific embodiment, under the flow condition, the zinc element in the first zinc-containing block 31 dissolves normally into the flowing water, and the alkaline substance in the second alkaline block 32 can also dissolve normally into the flowing water. Since the second alkaline block 32 is located downstream of the first zinc-containing block 31, the antagonistic substance will not affect the dissolution of minerals under the flow condition. Furthermore, since the flowing water stays at the first zinc-containing block 31 for a short time, the risk of the zinc content in the flowing water exceeding the standard is low.

[0056] When the filter element assembly 1 is not immersed in the outflowing water, the immersion water in the internal water path 11 no longer flows solely through the first zinc-containing block 31 and then through the second alkaline block 32. The immersion water connects the first zinc-containing block 31 and the second alkaline block 32, allowing alkaline substances to also move towards the first zinc-containing block 31. During immersion, the immersion water and the first zinc-containing block 31 have sufficient contact time, and the alkaline substances can inhibit the excessive dissolution of zinc into the immersion water, thereby controlling the zinc content in the immersion water and reducing the impact of immersion on the service life of the first zinc-containing block 31. Through the filter element assembly 1 structure provided in this application, the zinc content in the zinc mineralized water can be effectively controlled in both flow and immersion states, thereby improving the stability and usability of the filter element assembly 1.

[0057] Optionally, the fluid entering the inner water passage 11 through the inlet 111 simultaneously flows through the first zinc-containing block 31 and the second alkaline block 32, and then flows out from the outlet 112. In the structure provided in this specific embodiment, the dissolution of the first zinc-containing block 31 and the second alkaline block 32 does not interfere with each other in the flow state, and the alkaline substance can inhibit the large-scale dissolution of zinc elements into the soaking water in the soaking state. Therefore, regardless of the flow state or the soaking state, the content of zinc elements in the zinc mineralized water can be effectively controlled, thereby improving the stability and usability of the filter element assembly 1.

[0058] In one specific embodiment of this application, an inlet 111 and an outlet 112 are disposed on the filter cartridge 12. The internal water passage 11 also includes a central outlet channel 113, which extends axially through the zinc-containing filter body 2, the combined filter body 3, and the alkaline filter body 4 along the filter cartridge 12. The filter element assembly 1 also includes an end cap 13, which blocks one end of the central outlet channel 113, and the other end of the central outlet channel 113 is connected to the outlet 112.

[0059] In the structure provided in this specific embodiment, the central water outlet channel 113 can collect and guide the water filtered by the zinc-containing filter element 2, the combined filter element 3, and the alkaline filter element 4, so that this part of the fluid can be output to the outside through the water outlet 112. The end cap 13 can ensure that all water entering the central water outlet channel 113 is filtered by the filter element, thereby improving the stability and availability of the filter element assembly 1.

[0060] like Figure 6 As shown in a specific embodiment of this application, the first zinc-containing block 31 can be disposed on the outer periphery of the second alkaline block 32, and the second alkaline block 32 is disposed between the central water outlet channel 113 and the first zinc-containing block 31.

[0061] With the structure provided by this specific embodiment, in the flow state, it can be ensured that the water will flow through the first zinc-containing block 31 first and then through the second alkaline block 32, so that the dissolution of the first zinc-containing block 31 and the second alkaline block 32 will not interfere with each other; in the soaking state, the alkaline substance can inhibit the large-scale dissolution of zinc element into the soaking water. Therefore, whether in the flow state or the soaking state, the content of zinc element in zinc mineralized water can be effectively controlled, thereby improving the stability and usability of the filter element assembly 1.

[0062] In one specific embodiment of this application, the first zinc-containing block 31 and the second alkaline block 32 are arranged opposite to each other, and the first zinc-containing block 31 and the second alkaline block 32 surround each other to form a partial central water outlet channel 113 between the first zinc-containing block 31 and the second alkaline block 32.

[0063] With the structure provided in this specific embodiment, part of the water entering the central outlet channel 113 from the combined filter body 3 is filtered by the first zinc-containing block 31, and the other part is filtered by the second alkaline block 32. During flow, the dissolution of the first zinc-containing block 31 and the second alkaline block 32 does not interfere with each other; during soaking, the water fills the central outlet channel 113, so the alkaline substances can inhibit the large-scale dissolution of zinc into the soaking water. Regardless of whether it is in the flow or soaking state, the content of zinc in the zinc mineralized water can be effectively controlled, thereby improving the stability and usability of the filter element assembly 1.

[0064] In one specific embodiment of this application, the first zinc-containing block 31 is connected to the zinc-containing filter body 2, and the second alkaline block 32 is connected to the alkaline filter body 4. Both the first zinc-containing block 31 and the zinc-containing filter body 2 contain zinc elements that can be dissolved in water, and the two can be an integral structure; both the second alkaline block 32 and the alkaline filter body 4 contain alkaline elements that can be dissolved in water, and the two can be an integral structure.

[0065] The structure provided in this specific embodiment makes the connection between the zinc-containing filter body 2, the combined filter body 3, and the alkaline filter body 4 more compact, reducing the probability of water leakage at the joints and affecting the water quality of the filter element assembly 1.

[0066] See Figure 8 , Figure 8 This is a schematic diagram of the water circuit structure of an embodiment of the mineral water purifier provided in this application. In a specific embodiment of this application, the internal water circuit 11 may include a first internal water circuit 114, a second internal water circuit 115, and a third internal water circuit 116 that are connected in parallel and isolated from each other. A zinc-containing filter element 2 is disposed in the first internal water circuit 114, a combined filter element 3 is disposed in the second internal water circuit 115, and an alkaline filter element 4 is disposed in the third internal water circuit 116.

[0067] In the structure provided in this specific embodiment, by respectively arranging three filter elements in three internal water passages 11, water of different compositions can be output to the outside under flow conditions. Furthermore, valves can be respectively provided in the first internal water passage 114, the second internal water passage 115, and the third internal water passage 116, thereby controlling the outflow rate and flow velocity of water of different compositions, and thus adjusting the outflow water to obtain water with pH value and composition that meet the water requirements, such as alkaline water or zinc mineralized water, thereby improving the usability of the filter element assembly 1.

[0068] To address the aforementioned technical problems, one specific embodiment of this application also provides a mineral water purifier, including a main body 7 and a filter element assembly 1 as described in any of the above embodiments. The main body 7 is connected to the filter element assembly 1.

[0069] In the structure provided in this specific embodiment, the zinc-containing filter body 2, the combined filter body 3, and the alkaline filter body 4 are arranged in parallel. Under the condition that the filter element assembly 1 continuously discharges water, the zinc element in the first zinc-containing block 31 and the alkaline substance in the second alkaline block 32 in the combined filter body 3 normally dissolve into the water. At this time, the alkaline substance does not affect the dissolution of zinc element. Moreover, since the water stays at the zinc-containing filter body 2 and the first zinc-containing block 31 for a short time, the risk of the zinc element content in the water exceeding the standard is low. When the filter element assembly 1 is not immersed in the water, the immersion water no longer flows through the zinc-containing filter body 2, the combined filter body 3, and the alkaline filter body 4. The first zinc-containing block 31 and the second alkaline block 32 are simultaneously immersed in the water, allowing the alkaline substances to act on the first zinc-containing block 31. Although the immersion water and the first zinc-containing block 31 have sufficient contact time in the immersion state, the alkaline substances can inhibit the large-scale dissolution of zinc into the water during immersion, thereby controlling the zinc content in the water and reducing the impact of the immersion state on the service life of the mineralized filter material. With the filter element assembly 1 structure provided in this application, the zinc content in the mineralized water can be effectively controlled in both the flow state and the immersion state. Furthermore, the parallel arrangement of the zinc-containing filter body 2, the combined filter body 3, and the alkaline filter body 4 can also be used to output three types of water with different compositions to the filter element assembly 1, thereby improving the stability and usability of the mineral water purifier.

[0070] In a specific embodiment of this application, the main body 7 of the device may be provided with a first water inlet 71, a second water inlet 72, a third water inlet 73, and a water outlet 74. The main body 7 of the device includes a first valve body 711, a second valve body 721, and a third valve body 731. The first valve body 711 is connected to the first water inlet 71, the second valve body 721 is connected to the second water inlet 72, and the third valve body 731 is connected to the third water inlet 73. The filter element assembly 1 is provided with a first internal water channel 114, a second internal water channel 115, and a third internal water channel 116 that are connected in parallel and isolated from each other. The filter element assembly 1 includes a zinc-containing filter element 2, a combined filter element 3, and an alkaline filter element 4. The zinc-containing filter element 2 is disposed in the first internal water channel 114, the combined filter element 3 is disposed in the second internal water channel 115, and the alkaline filter element 4 is disposed in the third internal water channel 116. One end of the first water inlet 71 is connected to the first inner water inlet 114, one end of the second water inlet 72 is connected to the second inner water inlet 115, and one end of the third water inlet 73 is connected to the third inner water inlet 116. The other ends of the first water inlet 71, the second water inlet 72, and the third water inlet 73, which are away from the filter element assembly 1, are all connected to the water outlet 74.

[0071] In the structure provided in this specific embodiment, the three filter elements in the filter element assembly 1 are respectively disposed in three internal water passages 11, enabling them to output water of different compositions to the outside under flow conditions. Simultaneously, due to the presence of the first valve body 711, the second valve body 721, and the third valve body 731, the main body 7 of the device connected to the filter element assembly 1 can control the outflow volume and flow rate of water of different compositions through the first valve body 711, the second valve body 721, and the third valve body 731. This allows for the adjustment of the final output water from the mineral water purifier to obtain water with pH values ​​and compositions that meet water usage requirements, such as alkaline water or zinc-mineralized water, thereby improving the usability of the mineral water purifier.
