[0032] The various specific technical features and embodiments described in the specific implementation methods can be combined in any suitable manner unless there is any contradiction. 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 specific technical features / embodiments in the present invention will not be described separately.

[0033] The present invention provides a filter element component, such as Figures 1 to 5 As shown, it includes a mineralized filter element 100, and the mineralized filter element 100 includes a shell 110. A first filter chamber 111 and a second filter chamber 112 are arranged in the shell 110. A first filter body 131 is arranged in the first filter chamber 111, and a second filter body 132 is arranged in the second filter chamber 112. The second filter body 132 includes a mineralized filter body 1321; the first filter chamber 111 and the second filter chamber 112 are relatively isolated, that is, the first filter chamber 111 and the second filter chamber 112 are not directly connected.

[0034] The shell 110 is provided with a first water inlet 101 and a first water outlet 102, the first water inlet 101 and the first water outlet 102 are both connected to the first filter chamber 111, the first water inlet 101 is used to connect to the water supply pipeline 310, and the first water outlet 102 is used to connect to the water inlet end of an external filter material or an external pipeline through the first pipeline 320; the first filter body 131 is used to pre-filter the raw water, the raw water enters the first filter chamber 111 from the first water inlet 101, flows through the first filter body 131 and then flows out of the shell 110 from the first water outlet 102.

[0035] The housing 110 is further provided with a second water inlet 103 and a second water outlet 104, both of which are connected to the second filter chamber 112, the second water inlet 103 is used to connect to the water outlet of an external filter material or an external pipeline through a second pipeline 330, and the second water outlet 104 is used to connect to a mineralized water outlet pipeline 340. The second filter body 132 is used to perform mineralization treatment on the water flow, the water flow enters the second filter chamber 112 from the second water inlet 103, flows through the second filter body 132, and then flows out of the housing 110 from the second water outlet 104. After the water flows out of the shell 110 from the first water outlet 102, it can be filtered through an external filter material (the RO membrane filter element 200 in this embodiment) and then flow into the second water inlet 103, that is, the flow path of the raw water is as follows: the raw water enters the first filter chamber 111 from the first water inlet 101, flows through the first filter body 131, and then flows from the first water outlet 102 to the water inlet 201 of the RO membrane filter element 200, and is filtered by the RO membrane of the RO membrane filter element 200 to form pure water. The pure water flows from the water outlet 202 of the RO membrane filter element 200 to the second water inlet 103 and enters the second filter chamber 112, and then flows through the second filter body 132 to form mineralized water. The mineralized water flows from the second water outlet 104 to the water outlet pipeline 340 (faucet end). In this way, a first filter body 131 for pre-filtration and a mineralizing filter body 1321 for mineralizing the water body are provided in the filter element component, which is beneficial to dissolving an appropriate amount of minerals in the water body. Users can replenish minerals by drinking water, and the filter element component can be installed in a water purifier equipped with a pre-filter element and an RO membrane filter element 200, and directly replace the original pre-filter element. By replacing a filter element (that is, the pre-filter element of the original water purifier), the original water purifier can be upgraded to a mineral water purifier with a mineralization function, which is convenient for users to use.

[0036] Optionally, the first filter chamber 111 and the first filter body 131 are arranged close to the first end of the housing 110. In this embodiment, the first water inlet 101 and the first water outlet 102, the second water inlet 103 and the second water outlet 104 are all arranged at the first end of the housing 110, so that the filter element can be installed on the waterway plate, so that the filter element is connected to the waterway inside the waterway plate. The second filter chamber 112 and the second filter body 132 are arranged close to the second end of the housing 110, and the second filter body 132 also includes a post-filter body 1322. The mineralized filter body 1321 is far away from the second end of the housing 110 relative to the post-filter body 1322. Figure 7 The figure shows a schematic diagram of the water flow at the second filter body 132. It can be seen that the mineralized filter body 1321 is relatively far away from the area with a higher water flow velocity in the shell 110, which avoids the problem of excessive consumption of minerals in the mineralized filter body 1321 due to excessive flow velocity, resulting in a reduction in the life of the mineralized filter body 1321. At the same time, it also avoids large fluctuations in the mineral content in the mineralized water due to uneven water flow, and the mineral content in the mineralized water is relatively stable.

[0037] Optionally, the filter element component includes a central tube 150, the central tube 150 is disposed in the housing 110, the interior of the central tube 150 is communicated with the second water outlet 104, one end of the central tube 150 is close to the second end of the housing 110 and an end water flow channel 151 is formed between the central tube 150 and the second end of the housing 110, and the mineralized water flowing through the second filter body 132 enters the central tube 150 from the front end of the central tube 150 and flows toward the second water outlet 104. The end water flow channel 151 is close to the end of the housing 110, where the water flow is reversed and the channel is relatively narrow, which is generally the position of the housing 110 where the water flow velocity is the largest. By keeping the mineralized filter body 1321 away from the position where the water flow velocity is the largest, the loss of the mineralized filter body 1321 can be effectively reduced.

[0038] Alternatively, if Figures 1 to 3 as well as Figure 7 As shown, the second filter body 132 is in the shape of an integrally formed carbon rod. In a specific application, the post-filter body 1322 and the mineralized filter body 1321 can be integrally formed or fixedly connected by bonding or the like. The mineralized filter body 1321 and the post-filter body 1322 (post-carbon) are an integral structure, wherein the mineralized filter body 1321 is a carbon substrate, the mineralized filter body 1321 is a carbon rod containing mineralized materials, and the post-carbon is a pure carbon rod. The two can be bonded together after sintering to form an integral structure, and the mineralized filter body 1321 (mineralized carbon rod) is located in the maximum water flow area away from the top of the central tube 150. In this embodiment, the first filter body 131 and the second filter body 132 are both sleeved on the outside of the central tube 150, one end of the central tube 150 is close to the second end of the shell 110, and the other end of the central tube 150 is connected to the second water outlet 104.

[0039] Of course, in some applications, the mineralized filter 1321 and the post-filter 1322 may also be of a separate structure. The post-filter 1322 may also be of a substrate resistant to water flow erosion, such as a ceramic filter.

[0040] Specifically, an inner cylinder 160 may be disposed in the housing 110 to separate and form the first filter cavity 111 and the second filter cavity 112. In specific applications, the first filter cavity 111 and the second filter cavity 112 may also be separated by a partition or the like.

[0041] Optionally, the post-filter 1322 is a pure carbon rod, and the post-filter 1322 and the mineralized filter 1321 are arranged in parallel in the second filter chamber 112, and the water flowing into the second filter chamber 112 flows in parallel through the mineralized filter 1321 and the post-filter 1322. Optionally, the first filter 131 is a pre-filter for primary filtering of raw water, and the pre-filter may include a primary filter material such as PP cotton.

[0042] Optionally, the mineralized filter body 1321 may adopt a single mineralized filter material, such as an alkaline filter material, a zinc-containing filter material, or a metasilicic acid filter material.

[0043] Alternatively, the mineralized filter body 1321 may also adopt a combined mineralized filter material, and the combined mineralized filter body 1321 at least includes a first filter material and a second filter material.

[0044] The first filter material is a weak alkaline filter material, and the second filter material is a strong alkaline filter material; in a specific application, the first filter material is a weak alkaline filter material, and the second filter material is a strong alkaline filter material; the strong alkaline filter material may have a strong alkaline material, such as brucite, which has a chemical composition of Mg(OH)2 and can directly release (dissolve) OH in water. - (Reaction a: Mg(OH)2=Mg 2+ +2OH - ), increase the alkalinity of water, and the weak alkaline filter material can be calcite, etc. Taking calcite as an example, its chemical composition is CaCO3, and CO3 needs to be released in the water first 2- (Reaction b: CaCO3=Ca 2+ +CO3 2- ), then CO3 2- Hydrolysis reaction with H2O generates OH - (Reaction c: CO3 2- +H2O HCO3 - +OH - ), strong alkaline materials only need one step reaction to obtain OH - , weakly alkaline materials require two steps to produce OH - , and the rate of reaction c is much lower than that of reaction a, so the strong alkaline material releases OH preferentially. - Reaction c is a reversible reaction. When reaction a occurs first, the chemical equilibrium of reaction c moves to the left. Therefore, the strong alkaline material can inhibit the OH of the weak alkaline material. - When the strong alkaline material is combined with the weak alkaline material and the strong alkaline filter material and the weak alkaline filter material are in the same filter cavity, the strong alkaline filter material can be used to inhibit the weak alkaline filter material. During the service life of the filter element, the strong alkaline filter material releases OH in the early stage. - , and releases OH together with weakly alkaline filter materials in the middle and late stages -, the two can work together to greatly improve the life of the mineralized filter element 100. It can be seen that the first filter material is inhibited from dissolving alkaline substances in an environment with a water body having a pH value higher than a certain value. When the second filter material dissolves alkaline substances in the early stage, the pH value of the water body is higher than the set pH value, and when the second filter material dissolves alkaline substances in the later stage, the pH value of the water body will be lower than the set pH value; the second filter material and the first filter material are arranged in the same filter cavity, and the second filter material and the first filter material are immersed in the water body of the filter cavity. When the alkaline water body in the filter cavity is higher than the set pH value, the alkaline substances of the first filter material are inhibited and cannot (basically cannot) be dissolved. An integrated filter element can be used. When the alkalization ability of the second filter material gradually decreases, the inhibitory effect of the second filter material on the second alkaline filter body is gradually alleviated, and the second alkaline filter body can also gradually and slowly release alkaline substances. The second filter material and the first filter material can cooperate to alkalize the water body, which greatly improves the service life of the filter element.

[0045] Alternatively, the first filter material is a zinc mineralized filter material or a copper mineralized filter material, and the second filter material is an alkaline filter material; taking the zinc mineralized filter material as an example, the first filter material can normally dissolve the zinc element when flowing, and the alkaline water provided by the alkaline filter material can utilize the inhibitory effect of the alkaline water on the dissolution of the zinc element. When water production is stopped, the zinc mineralized filter material can be soaked in the alkaline water. In the soaking state, the zinc dissolution of the zinc mineralized filter material can be prevented from exceeding the limit. This can not only provide zinc-rich drinking water that meets the standards, but also solve the technical problem that the zinc-containing filter material is easy to dissolve beyond the limit when soaked, thereby preventing users from drinking water containing excessive zinc and causing negative effects on their health. In specific applications, the first filter material can dissolve zinc, and the second filter material can be a weakly alkaline filter material. When water flows normally through the first filter material and the second filter material, zinc can be dissolved normally. When the water flow stops, there is soaking water in the second filter chamber 112 filter element. If the soaking water body is non-alkaline water, the dissolution amount of zinc 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 this embodiment, by setting the second filter material as an alkaline filter material, the soaking water body can be made weakly alkaline, thereby inhibiting the excessive dissolution of zinc in the first filter material, so that the zinc concentration in the soaking water body also meets the national standard, and can prevent the zinc element in the water body from exceeding the set range under the soaking condition. The mechanism of inhibiting the dissolution of zinc by soaking in alkaline water can not only make the zinc element dissolve normally when the flow is overflowing (normal water flow), but also overcome the technical difficulty that the zinc mineralization filter material is easy to cause the zinc element to exceed the standard when soaking.

[0046] Alternatively, the first filter material is a mineralized filter material containing calcium and / or magnesium, and the second filter material is an alkaline filter material; or, the first filter material is a mineralized filter material containing calcium and / or magnesium, and the second filter material is an acidic filter material, so as to meet the personalized needs of different users. In specific applications, the mineralized filter body 1321 can also use a metasilicic acid filter material. For example, the first filter material is an alkaline filter material, and the second filter material is a metasilicic acid filter material. In the second filter chamber 112, water flows through the alkaline filter material and the metasilicic acid filter material at the same time, so that the weakly alkaline water body formed by the alkaline filter material acts on the metasilicic acid filter material, thereby promoting the metasilicic acid filter material to form metasilicic acid in the water. Metasilicic acid (H2SiO3) is generated by the hydrolysis reaction of silicate ores in water. Taking sodium silicate (Na2SiO3) as an example of silicate ores, SiO3 2- +H2O H2SiO3+2OH - , H2SiO3+H2O H4SiO4, but metasilicic acid and orthosilicic acid (H4SiO4) exist in a dynamic equilibrium. In weakly alkaline water, H2SiO3+H2O The balance of H4SiO4 shifts to the left, that is, the content of orthosilicic acid decreases, and the concentration of metasilicic acid increases. Hydroxyl ions are formed by alkaline filter materials. The water containing hydroxide ions acts on the metasilicic acid filter materials, thereby promoting the dissolution rate of silicon in the metasilicic acid filter materials. The concentration of metasilicic acid formed in the water is relatively high, which makes the drinking water taste better.

[0047] Optionally, the filter element component further includes an external filter element, the external filter element is connected to the waterway between the first water outlet 102 and the second water inlet 103, and the external filter element is an RO membrane filter element 200, such as Figure 1 The mineralized filter element 100 and the RO membrane filter element 200 can be connected to the same waterway plate, and the waterway plate connects the RO membrane filter element 200 between the first water outlet 102 and the second water inlet 103. The RO membrane filter element 200 and the mineralized filter element 100 as filter element components can be connected to a traditional mineral water purifier to achieve product upgrade.

[0048] The present invention provides a mineral water purifier, such as Figures 1 to 7As shown, the mineral water purifier includes the above-mentioned filter element component. The mineral water purifier has a waterway plate, and the waterway plate can be provided with two filter element connection seats, which are respectively used to connect the above-mentioned mineralized filter element 100 and RO membrane filter element 200, that is, the waterway plate can be provided with a pipeline for connecting the mineralized filter element 100 and the RO membrane filter element 200. The water circuit board is connected to a water supply pipeline 310. The raw water supply pipeline 310 enters the water circuit board, enters the first filter chamber 111 from the first water inlet 101 through the first water supply pipeline 310 of the water circuit board, flows through the first filter body 131, and then flows from the first water outlet 102 to the first internal water channel of the water circuit board, and then flows to the water inlet 201 of the RO membrane filter element 200. After being filtered by the RO membrane, pure water is formed. The pure water flows from the water outlet 202 of the RO membrane filter element 200 to the second internal water channel of the water circuit board. The second internal water channel is connected to the second water inlet 103 of the mineralized filter element 100. The pure water can enter the second filter chamber 112 of the mineralized filter element 100 from the second water inlet 103 through the second internal water channel, and then flows through the second filter body 132 to form mineralized water. The mineralized water flows from the second water outlet 104 to the water outlet pipeline 340 of the water circuit board. It should be noted that Figure 6 The two dotted frames in the middle are the same mineralized filter element 100. To facilitate the display of the water path, different cross-sections of the same mineralized filter element 100 are displayed.

[0049] Optionally, the mineral water purifier has a water system, and the water system has an inlet end and an outlet end. The first filter 131 and the RO membrane filter element 200 are sequentially connected to the inlet end along the water flow direction, and the mineralized filter 1321 and the post-filter 1322 are arranged in parallel between the downstream of the RO membrane filter element 200 and the outlet end. The water flow can be arranged to first flow through the pre-filter, then flow through the RO membrane, and then flow through the mineralized filter 1321 (carbon rod shape) and the post-filter 1322 (pure carbon) respectively, and then merge to flow to the outlet end. In specific applications, the water inlet end and the water outlet end can be respectively provided with water quality sensors, and the water quality sensors can be pH sensors or / and TDS sensors to detect the water quality of the inlet and outlet water. When the mineralized filter 1321 is provided with alkaline filter material, the outlet pipe 340 can be provided with a pH sensor, and the pH sensor is used to detect the pH value of the outlet water. A TDS sensor is a device used to measure the total dissolved solids (TDS) in water. It can continuously monitor the conductivity value of the object being measured. The mineral content in the object being measured is calculated based on the conductivity value, thereby characterizing the mineral content of the water body.

[0050] In specific applications, the water outlet pipeline 340 may be connected in parallel with a pure water circuit, and the water outlet pipeline 340 and the pure water circuit are connected with a shunt control valve. The water outlet end of the water outlet pipeline 340 may be provided with a water quality sensor. When the pH value or TDS of the water outlet of the water outlet pipeline 340 is too high, the pure water of the pure water circuit and the mineralized water of the water outlet pipeline 340 may be mixed through the shunt control valve to make the pH value or the concentration of the mineralized substance of the water outlet within a suitable range, so as to avoid the pH value or the concentration of the mineralized substance of the water outlet exceeding the standard range. In some embodiments, one end of the pure water circuit is connected to the water outlet of the RO membrane filter element 200, and the water outlet pipeline 340 may also be controlled by the valve body to provide pure water to meet different user needs.

[0051] In a specific application, the water inlet pipeline or the water outlet pipeline 340 may be provided with a control valve, and the control valve is electrically connected to the control module. In a specific application, the water inlet pipeline may be provided with a flow meter. The control module may adjust the control valve according to the setting of the water outlet to make the water production meet the set requirements.

[0052] The filter element component and the mineral water purifier provided by the present invention are provided with a first filter body 131 for pre-filtration and a mineralized filter body 1321 for mineralizing the water body, which is conducive to dissolving an appropriate amount of minerals in the water body. The user can replenish the minerals by drinking water. Moreover, the filter element component can be installed in a water purifier provided with a pre-filter element and an RO membrane filter element 200, and directly replace the original pre-filter element for use. The original pre-filter element is replaced with the above-mentioned mineralized filter element 100, so that the original water purifier is upgraded to a mineral water purifier with a mineralization function. The user is convenient to use. The second filter body 132 also includes a post-filter body 1322. The mineralized filter body 1321 is relatively far away from the second end of the shell 110 relative to the post-filter body 1322. In this way, the mineralized filter body 1321 is relatively far away from the area with a large water flow rate in the shell 110, thereby avoiding the problem of excessive consumption of minerals in the mineralized filter body 1321 due to excessive flow rate, thereby reducing the life of the minerals. At the same time, it also avoids the large fluctuation of the mineral content in the mineralized water due to uneven water flow, and the mineral content in the mineralized water is relatively stable.
