Abstract
Description
Technical Field
[0001] This application relates to the field of mineralized drinking water equipment technology, specifically to a mineralized filter element component, filter element device, and mineral spring mineralization equipment. Background Technology
[0002] As people's living standards continue to improve, their demands for drinking water quality are also increasing. In recent years, mineralized water, due to its rich content of various minerals beneficial to the human body, has gradually become the preferred drinking water for many consumers. Currently, mineralization filter cartridges are one of the main methods for preparing mineralized water. Mineralization filter cartridges contain various minerals; when water flows through or soaks the cartridge, these minerals are gradually released into the water, thus transforming ordinary tap water into mineralized water rich in minerals such as calcium, magnesium, and potassium.
[0003] However, some problems exist in the use of this type of mineralizing filter cartridge. When the filter cartridge is soaked in water for a long time, the mineral concentration in the water will rise rapidly and the total amount of dissolved minerals will be relatively large because the internal mineralizing filter material is completely submerged in the water inside the filter cartridge shell. If the mineralizing filter cartridge is soaked for an extended period, the concentration of minerals such as calcium, magnesium, and zinc contained in the filter cartridge may exceed the normal range. Excessively high mineral concentrations may have certain adverse effects on human health. Utility Model Content
[0004] In view of this, this application provides mineralization filter element components, filter element devices, and mineral water mineralization equipment, which can solve the problem that the mineral content in the water is prone to exceed the standard when the mineralization filter element is soaked, and effectively control the mineral content in the mineralized water.
[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application is: to provide a mineralized filter element component, comprising:
[0006] The housing has a pre-filter chamber and a mineralization filter chamber inside. The pre-filter chamber and the mineralization filter chamber are relatively isolated and connected by a pressure conducting component. The pressure conducting component is connected under the action of water flow pressure, so that the pre-filter chamber and the mineralization filter chamber are connected in series. The pre-filter chamber is provided with pre-filter media, and the mineralization filter chamber is provided with mineralization filter media. The housing has an inlet port and an outlet port. The inlet port is connected to the pre-filter chamber, and the outlet port is connected to the mineralization filter chamber.
[0007] Optionally, the pre-filter chamber and the mineralization filter chamber are arranged along the axial direction of the housing;
[0008] Alternatively, the pre-filter chamber and the mineralization filter chamber are arranged radially along the housing.
[0009] Optionally, the pressure-conducting component is a one-way valve;
[0010] Alternatively, the pressure conducting component may be an elastic diaphragm with slits.
[0011] Optionally, the housing is provided with a partition that divides the interior of the housing into the pre-filter chamber and the mineralization filter chamber, and the pressure conducting component is disposed on the partition.
[0012] Optionally, the pre-filter material includes PP cotton and / or activated carbon;
[0013] And / or, the mineralized filter material includes zinc filter material, alkaline filter material or metasilicic acid filter material.
[0014] This application also provides a filter cartridge device, including a filter cartridge and the above-mentioned mineralized filter cartridge component, wherein the mineralized filter cartridge component is encapsulated within the filter cartridge.
[0015] Optionally, the filter cartridge is provided with a buffer chamber located outside the mineralization filter element component, and a unidirectional conduction component that can conduct under unidirectional water pressure is provided between the mineralization filter chamber of the mineralization filter element component and the buffer chamber.
[0016] Optionally, the one-way conduction component is a one-way valve.
[0017] Optionally, the buffer chamber is provided with a nanofiltration element and / or activated carbon filter material.
[0018] This application also provides a mineral spring mineralization device, including a main body and the aforementioned filter element device, wherein the filter element device is connected to the main body of the device.
[0019] This application provides a mineralization filter element component, filter element device, and mineral spring mineralization equipment. The housing has a pre-filter chamber and a mineralization filter chamber inside. The pre-filter chamber and the mineralization filter chamber are relatively isolated and connected by a pressure conducting component. The pressure conducting component is connected under the action of water flow pressure, so that the pre-filter chamber and the mineralization filter chamber are connected in series. The pre-filter chamber is provided with pre-filter material, and the mineralization filter chamber is provided with mineralization filter material. The housing has a water inlet and a water outlet. The water inlet is connected to the pre-filter chamber, and the water outlet is connected to the mineralization filter chamber. The inlet, pre-filter chamber, mineralization filter chamber, and outlet are connected in series to form a series water circuit. Water flows into the housing of the mineralization filter element from the inlet, and then flows through the pre-filter media (pre-filter element) of the pre-filter chamber and the mineralization media (mineralization filter element) of the mineralization filter chamber. Finally, it flows out of the housing of the mineralization filter element from the outlet. Since a pressure conducting component is installed between the pre-filter chamber and the mineralization filter chamber, the pressure conducting component is activated when water flows through, allowing the water to flow normally through the pre-filter chamber and the mineralization filter chamber. When the water flow stops, there is no water pressure in the series water circuit, the pressure conducting component remains in the closed state, the water between the pre-filter chamber and the mineralization filter chamber is not interconnected, the mineralization filter chamber has a small volume and little water, even if the mineralization filter material is in a saturated state of dissolution, its total mineralization content is relatively low, and it is easily diluted to meet the safety standard range when the water is discharged. The technical solution of this application, by setting a pre-filter chamber that can be isolated in a static state (when there is no water flow in the water circuit) in the shell, can significantly limit the water storage volume of the mineralization filter chamber. When water production is not required, no water flows through the mineralization filter element, and the water in the mineralization chamber is not connected to the water in the pre-filter chamber. Even if the mineralization filter element is soaked for a long time, the total amount of mineralized substances saturated and dissolved in the water in the mineralization chamber is relatively small. Thus, when the mineralization filter element is used again to prepare mineralized water, the non-mineralized water in the pre-filter chamber can enter the mineralization chamber under the action of water flow. Since the volume of high-concentration mineralized water is relatively small, its high concentration of mineralized water can be quickly diluted, thereby effectively preventing the concentration of mineralized water flowing out of the filter element from exceeding the standard.

[0032] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0033] As people's living standards continue to improve, their demand for drinking water is also increasing, and mineralized water has become a popular choice for drinking water.
[0034] Currently, mineralized water is typically prepared using mineralization filter cartridges. The minerals in these cartridges are released into the water as it flows through or is immersed in the cartridge, transforming the water into mineralized water. However, when the filter cartridge is immersed in water, the prolonged contact time between the cartridge and the water, and the fact that the filter media is housed within a casing and submerged in all the water within the casing, can easily lead to a high concentration of minerals in the water and a significant amount of dissolution. This can result in excessively high mineral content in the water, which may have negative effects on human health.
[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] like Figure 1 , Figure 2As shown, this embodiment provides a mineralization filter element component 100, including a housing 110. The housing 110 has a pre-filter chamber 120 and a mineralization filter chamber 130 inside. The pre-filter chamber 120 and the mineralization filter chamber 130 are relatively isolated and connected by a pressure conducting component 140. The pressure conducting component 140 is opened under the action of water flow pressure, so that the pre-filter chamber 120 and the mineralization filter chamber 130 are connected in series. A pre-filter material 121 is disposed in the pre-filter chamber 120, and a mineralization filter material 131 is disposed in the mineralization filter chamber 130. The housing 110 has a water inlet 101 and a water outlet 102. The water inlet 101 is connected to the pre-filter chamber 120, and the water outlet 102 is connected to the mineralization filter chamber 130. The inlet port 101, the pre-filter chamber 120, the mineralization filter chamber 130, and the outlet port 102 can be connected in series to form a series water circuit. That is, the water flows into the housing 110 of the mineralization filter element component 100 from the inlet port 101, and flows through the pre-filter material 121 (pre-filter element) of the pre-filter chamber 120 and the mineralization filter material 131 (mineralization filter element) of the mineralization filter chamber 130 in turn, and then flows out of the housing 110 of the mineralization filter element component from the outlet port 102. Since a pressure conducting component 140 is provided between the pre-filter chamber 120 and the mineralization filter chamber 130, the pressure conducting component 140 is open when water flows through, and the water can flow normally through the pre-filter chamber 120 and the mineralization filter chamber 130. When the water flow stops, there is no water pressure in the series water circuit, the pressure conducting component 140 remains in the closed state, and the water between the pre-filter chamber 120 and the mineralization filter chamber 130 is not interconnected. The mineralization filter chamber 130 has a small volume and a small water capacity. Even if the mineralization filter material 131 is in a saturated state of dissolution, its total mineralization content is relatively low. When the water is discharged, it is easily diluted to meet the safety standard range. The technical solution of this application, by setting a pre-filter chamber 120 in the shell 110 that can be isolated in a static state (when there is no water flow in the water circuit), can significantly limit the water storage volume of the mineralization filter chamber 130. When water production is not required, no water flows through the mineralization filter element 100, and the water in the mineralization filter chamber 130 is not connected to the water in the pre-filter chamber 120. Even if the mineralization filter element is soaked for a long time, the total amount of mineralized substances saturated and dissolved in the water in the mineralization filter chamber 130 is relatively small. Thus, when the mineralization filter element 100 is used again to prepare mineralized water, the non-mineralized water in the pre-filter chamber 120 can enter the mineralization filter chamber 130 under the action of water flow. Since the volume of high-concentration mineralized water is relatively small, its high concentration of mineralized water can be quickly diluted, thereby effectively preventing the concentration of mineralized water flowing out of the filter element from exceeding the standard, so as to avoid the user drinking water with excessive mineralization, and the safety and reliability are relatively good.
[0037] Optionally, such as Figure 1 , Figure 2As shown, the pre-filter chamber 120 and the mineralization filter chamber 130 are arranged along the axial direction of the housing 110, that is, the pre-filter chamber 120 and the mineralization filter chamber 130 are arranged vertically along the height direction of the housing 110, forming an axial vertical structure. Of course, in specific applications, the mineralization filter chamber 130 can be arranged above or below the pre-filter chamber 120.
[0038] Alternatively, the pre-filter chamber 120 and the mineralization filter chamber 130 are arranged radially along the housing 110, that is, the pre-filter chamber 120 is arranged around the outer side of the mineralization filter chamber 130, or the mineralization filter chamber 130 is arranged around the outer side of the pre-filter chamber 120, and the pre-filter chamber 120 and the mineralization filter chamber 130 form an inner and outer jacket structure. Figure 2 The arrows in the diagram illustrate the direction of water flow in this embodiment. In practical applications, as an alternative, the direction of water flow can also be the same as... Figure 2 The directions indicated by the middle arrows are opposite. In the pre-filter chamber 120, the water flow can be radially inward and outward, or radially outward and inward (e.g., ...). Figure 7 As shown, the conduction direction of the pressure conduction component 140 and the position of the inlet and outlet water pipes can be adjusted according to the selected water flow direction.
[0039] Optionally, such as Figure 1 , Figure 2 As shown, the pressure-conducting component 140 can be a one-way valve, which can open in one direction under the action of water flow, allowing water to flow in one direction. Alternatively, the pressure-conducting component 140 can be an elastic diaphragm 410 with slits (see reference). Figure 6 (As shown). The elastic diaphragm 410 can be made of rubber sheet, and can have a straight or cross-shaped slit 411 on it. When water flows through, the slit 411 deforms under the impact of the water flow, allowing water to flow through the slit 411 of the elastic diaphragm 410. When the water flow stops, since there is no water pressure in the water path, the slit 411 closes under the elastic restoring force, thus isolating the pre-filter chamber 120 and the mineralization filter chamber 130. There can be one or at least two elastic diaphragms 410. Two elastic diaphragms 410 can be spaced apart.
[0040] Optionally, such as Figure 1 , Figure 2 As shown, a partition 191 is provided inside the housing 110. The outer side of the partition 191 can be attached to the inner peripheral sidewall of the housing 110. The partition 191 divides the interior of the housing 110 into the pre-filter chamber 120 and the mineralization filter chamber 130. The pressure conducting component 140 can be disposed on the partition 191. Specifically, one or more pressure conducting components 140 can be provided. The partition 191 can be provided with one or more channels, and correspondingly, one or more pressure conducting components 140 can be disposed at the channels.
[0041] Optionally, the pre-filter material 121 includes PP cotton and / or activated carbon. PP cotton is a filter material made of polypropylene fibers, which has a porous structure and a large specific surface area, effectively intercepting large particulate impurities in the water, such as silt, rust, and suspended solids, thus playing a preliminary role in purifying the water. Activated carbon has a highly developed pore structure and a large specific surface area, capable of adsorbing odors, discoloration, residual chlorine, and organic matter in the water. Through adsorption, activated carbon can effectively remove odors and discoloration from the water, improving its taste and aroma, while also removing harmful organic matter and residual chlorine, thus enhancing water safety and drinking comfort.
[0042] Optionally, the mineralized filter media 131 includes zinc filter media, alkaline filter media, or metasilicic acid filter media. Zinc is one of the essential trace elements for the human body. Adequate zinc intake helps maintain normal appetite, enhance immunity, and promote wound healing. Alkaline filter media are typically used to adjust the pH of water, making it slightly alkaline. Slightly alkaline water helps neutralize acidic substances in the body, maintaining the body's acid-base balance and having a positive effect on promoting health. Metasilicic acid is a mineral beneficial to the human body, with functions such as softening blood vessels and promoting bone health. Furthermore, metasilicic acid can improve the taste of water, making it sweeter. The use of these mineralized filter media 131 can effectively increase the mineral content and health value of drinking water, while also improving the taste and safety of the water.
[0043] like Figures 3 to 5 As shown, this application also provides a filter element device 200, including a filter cartridge 210 and the aforementioned mineralized filter element component 100, wherein the mineralized filter element component 100 is encapsulated within the filter cartridge 210. The mineralized filter element component 100, as a filter element unit, can be encapsulated independently or within the filter cartridge 210, and can be used in conjunction with other filter media.
[0044] Optionally, the filter cartridge 210 is provided with a buffer chamber 240 located outside the mineralization filter element component 100. A unidirectional flow component 230, which can be connected under unidirectional water pressure, is provided between the mineralization filter chamber 130 of the mineralization filter element component 100 and the buffer chamber 240. The unidirectional flow component 230 can be provided at the above-mentioned outlet port 102. Water flows from the central pipe of the filter element device 200 to the inlet port 101 and enters the housing 110 of the mineralization filter element component 100. It then flows through the pre-filter material 121 (pre-filter) of the pre-filter chamber 120 and the mineralization filter material 131 (mineralization filter) of the mineralization filter chamber 130, and then flows out of the housing 110 of the mineralization filter element component from the outlet port 102. The water flows through the unidirectional flow component 230 of the outlet port 102, through the buffer chamber 240, and then out of the filter element device 200.
[0045] Optionally, such as Figures 3 to 5As shown, the one-way guiding component 230 is a one-way valve. In specific applications, the aforementioned one-way valve can be a duckbill valve, which has a simple structure, no impact on water quality, and low application cost. Duckbill valves are typically made of rubber and are shaped like a duck's bill. When there is no internal pressure, the duckbill outlet closes due to its own elasticity; as the internal pressure gradually increases, the duckbill outlet gradually widens, ensuring liquid can still be discharged. When the liquid flows forward, the pressure pushes the duckbill-shaped rubber valve open, allowing the liquid to pass smoothly; if the liquid stops or flows in reverse, the valve's elasticity will automatically close it, preventing backflow.
[0046] Of course, check valves can also be magnetic check valves, ball check valves, spring check valves, etc. The structure of a ball check valve mainly consists of a valve body, valve seat, and valve ball. The valve ball is generally a silicone or rubber ball, and can be hollow or solid. When the fluid pressure on the inlet side exceeds the opening pressure, the valve ball moves away from the valve seat, allowing fluid flow; when the inlet pressure does not exceed the opening pressure or there is back pressure, the valve ball, with the help of back pressure or spring force, tightly adheres to the valve seat, effectively preventing reverse flow of fluid. A spring check valve consists of a valve body, valve disc, and spring, with the valve disc connected to the spring. When water enters through inlet 131, the water pressure overcomes the spring force, opening the valve disc and allowing water to flow smoothly; when the water flow stops or reverses, the spring force pushes the valve disc back to its original position, tightly adhering to the valve seat and preventing backflow.
[0047] Optionally, the buffer chamber 240 is equipped with a buffer filter element, which can be a nanofiltration element or / and activated carbon filter media. A nanofiltration element is an innovative filter element type that falls between ultrafiltration and reverse osmosis, developed through the cross-fertilization of advanced nanotechnology and traditional filtration techniques. Its separation performance relies on the nanoscale microporous structure in its active separation layer, and its separation mechanism follows the adsorption-dissolution-diffusion-filtration model. It retains organic matter and heavy metals that can pass through ultrafiltration while allowing some minerals retained by reverse osmosis to pass through, enabling simultaneous concentration and salt permeation processes to achieve specific separation and purification requirements. Activated carbon filter media can effectively adsorb and eliminate odors in water.
[0048] This application also provides a mineral spring mineralization device, including a main body and the aforementioned filter element device 200, wherein the filter element device 200 is connected to the main body.
[0049] In specific applications, an antagonistic filter element can also be installed in the pre-filter chamber 120. This antagonistic filter element is used to inhibit the release of minerals from the mineralization filter element 200 into the water. When the pre-filter chamber 120 is located upstream of the mineralization filter chamber 130, an antagonistic filter element is installed in the pre-filter chamber 120. This antagonistic filter element can dissolve antagonistic substances into the water, which are used to inhibit the release of minerals from the mineralization filter element 200 into the water. The water first flows through the antagonistic filter element and then through the mineralization filter element 200. The antagonistic substances dissolved by the antagonistic filter element come into contact with the mineralization filter chamber 130 along with the water, thereby inhibiting excessive dissolution of minerals in the mineralization filter chamber 130 and reducing the mineral content in the mineralized water during immersion.
[0050] In specific applications, the mineralizing filter element 200 can be a zinc mineralizing filter element or a copper mineralizing filter element. The antagonistic filter element can be an alkaline filter element. The water flow first contacts the alkaline filter element and then contacts the mineralizing filter chamber 130. The alkaline substances dissolved in the water by the alkaline filter element can come into contact with the mineralizing filter chamber 130 with the water flow, thereby inhibiting the excessive dissolution of zinc and copper elements in the mineralizing filter chamber 130 to a certain extent. Optionally, the antagonistic filter element can include at least one of the following materials: calcite, aragonite, magnesite, dolomite, etc.
[0051] Adsorption filter cartridges may include at least one of ion exchange resin filter cartridges, reverse osmosis filter cartridges, activated alumina filter cartridges, KDF (high-purity copper-zinc alloy) filter cartridges, and zeolite filter cartridges.
[0052] Ion exchange resin filter cartridges can adsorb at least one of the following mineral elements: calcium, magnesium, lead, and copper. Reverse osmosis filter cartridges can adsorb at least one of the following mineral elements: calcium, magnesium, sodium, fluorine, arsenic, and nitrates. Activated alumina filter cartridges can adsorb fluorides, arsenic, and sulfides. KDF (high-purity copper-zinc alloy) filter cartridges can adsorb lead, mercury, chlorine, hydrogen sulfide, and some calcium- and magnesium-containing minerals. Zeolite filter cartridges can adsorb ammonia nitrogen, some heavy metals, and radioactive substances.
[0053] This application also provides a mineral spring mineralization device, including a main body and the aforementioned mineralization filter element 100, wherein the mineralization filter element 100 is connected to the main body.
[0054] Understandably, the buffer chamber 240 and the buffer filter element can also be encapsulated separately in the inner shell. This can be achieved by setting two inner shells inside the filter cartridge 210 and connecting them through corresponding pipelines and one-way valves.
[0055] This application provides a mineralization filter element component, filter element device, and mineral spring mineralization equipment, such as Figure 2 , Figure 4 , Figure 5As shown, the housing 110 has a pre-filter chamber 120 and a mineralization filter chamber 130 inside. The pre-filter chamber 120 and the mineralization filter chamber 130 are relatively isolated and connected by a pressure conducting component 140. The pressure conducting component 140 is opened under the action of water flow pressure, so that the pre-filter chamber 120 and the mineralization filter chamber 130 are connected in series. The pre-filter chamber 120 is provided with pre-filter material 121, and the mineralization filter chamber 130 is provided with mineralization filter material 131. The housing 110 has a water inlet 101 and a water outlet 102. The water inlet 101 is connected to the pre-filter chamber 120, and the water outlet 102 is connected to the mineralization filter chamber 130. Water flows from the central pipe 270 of the filter cartridge device 200 to the inlet port 101, entering the housing 110 of the mineralization filter cartridge component 100. It then flows successively through the pre-filter media 121 (pre-filter cartridge) of the pre-filter chamber 120 and the mineralization filter media 131 (mineralization filter cartridge) of the mineralization filter chamber 130. Finally, it flows out of the housing 110 of the mineralization filter cartridge component from the outlet port 102. The water then passes through the one-way guide component 230 of the outlet port 102, flows through the buffer chamber 240, and exits the filter cartridge device 200. Because a pressure conduction component 140 is provided between the pre-filter chamber 120 and the mineralization filter chamber 130, the pressure conduction component 140 is activated when water flows through, allowing the water to flow normally through both chambers. A one-way valve 150 can also be installed at the central pipe 270. When the water flow stops, there is no water pressure in the series water circuit, the pressure conducting component 140 remains in the closed state, and the water between the pre-filter chamber 120 and the mineralization filter chamber 130 is not interconnected. The mineralization filter chamber 130 has a small volume and little water. Even if the mineralization filter material 131 is in a saturated state of dissolution, its total mineralization content is relatively low. When the water is discharged, it is easily diluted to meet the safety standard range. The technical solution of this application, by setting a pre-filter chamber 120 and a buffer chamber 240 that can be isolated in a static state (when there is no water flow in the water circuit) in the shell 110, can significantly limit the water storage volume of the mineralization filter chamber 130. When water production is not required, no water flows through the mineralization filter element 100, and the water in the mineralization filter chamber 130 is not connected to the water in the pre-filter chamber 120. Even if the mineralization filter element is soaked for a long time, the total amount of mineralized substances saturated and dissolved in the water in the mineralization filter chamber 130 is relatively small. Thus, when the mineralization filter element 100 is used again to prepare mineralized water, the non-mineralized water in the pre-filter chamber 120 can enter the mineralization filter chamber 130 under the action of water flow. Since the volume of high-concentration mineralized water is relatively small, its high-concentration mineralized water can be quickly diluted, thereby effectively preventing the concentration of mineralized water flowing out of the filter element from exceeding the standard.
