Description

Technical Field

[0002] With the improvement of productivity, people's demands for the quality of life and convenience are also increasing day by day. Mineralized water is a kind of water body containing minerals, rich in macroelements and trace elements essential to the human body. Therefore, mineralized water is favored as drinking water. At the same time, there is also a certain demand for mineralized water containing specific minerals during production and experiments.

[0003] Currently, mineralized water is usually prepared by using mineralization filter media. The soluble mineral salts in the mineralization filter media can be released into the water body during the process of water flowing through or soaking the mineralization filter media, turning the water body into mineralized water containing minerals. However, it is difficult to effectively control the mineral content in the mineralized water prepared by this method. Especially when the mineralization filter media is soaked in the water body, since the contact time between the mineralization filter media and the water body is relatively long, and since the mineralization filter media of the mineralization filter element is arranged in the housing, the mineralization filter media is soaked in all the stored water in the housing, and the minerals in the water body are very likely to reach a relatively high concentration and the total dissolution amount is relatively high, which may easily lead to the excessive mineral content in the water body. When the mineral content exceeds the standard, the mineralized water is likely to bring negative impacts to users. Summary of the Utility Model

It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0031] With the improvement of productivity, people's demands for the quality of life and convenience are also increasing day by day. Mineralized water is a kind of water body containing minerals, rich in essential macroelements and trace elements for the human body. Therefore, mineralized water is favored as drinking water. At the same time, there is also a certain demand for mineralized water containing specific minerals during production and experiments.

[0032] Currently, mineralized water is usually prepared using mineralized filter media. The soluble mineral salts in the mineralized filter media can be released into the water body during the process of water flowing through or soaking the mineralized filter media, turning the water body into mineralized water containing minerals. However, it is difficult to effectively control the mineral content in the mineralized water prepared by this method. Especially when the mineralized filter media is soaked in the water body, since the contact time between the mineralized filter media and the water body is relatively long, and since the mineralized filter media of the mineralized filter element is arranged in the housing, the mineralized filter media is soaked in all the stored water in the housing, the minerals in the water body are very likely to reach a relatively high concentration and the total dissolution amount is relatively high, which may very likely lead to the excessive mineral content in the water body. When the mineral content exceeds the standard, the mineralized water is instead likely to bring negative impacts to users.

[0033] In order to improve or solve the above technical problems, the inventors of this application have conducted long-term research and proposed at least the following embodiments.

[0034] Refer to Figures 1 to 4 , Figure 1 which is a schematic assembly structure diagram of an embodiment of the filtering device provided by this application. Figure 2 is Figure 1 the sectional structure diagram of the section shown by A-A in Figure 3 which is the sectional structure diagram of the section shown by A-A of another embodiment of the filtering device provided by this application. Figure 4 which is the sectional structure diagram of the section shown by A-A of still another embodiment of the filtering device provided by this application. The specific embodiment of this application provides a filtering device 1, and this filtering device 1 includes a filter element main body 2 and a mineralized filter media 3.

[0035] The filter element main body 2 may specifically include a rear housing 21, and a first cavity 211 and a second cavity 215 that are isolated from each other are formed in the rear housing 21. The filter element main body 2 may be provided with a first water passage 212, a second water passage 216, and one or at least two first one-way conduction structures 24. The first water passage 212 communicates with the first cavity 211, and the second water passage 216 communicates with the second cavity 215, so that the water inlet or outlet of the first cavity 211 can be realized through the first water passage 212, and the water inlet or outlet of the second cavity 215 can be realized by using the second water passage 216. The mineralization filter material 3 is accommodated in the first cavity 211 or the second cavity 215.

[0036] The first one-way conduction structure 24 is used to open under the action of a one-way water pressure to communicate the first cavity 211 and the second cavity 215. When there is no water flow pressure, the first one-way conduction structure 24 remains closed, and the first cavity 211 and the second cavity 215 are relatively isolated, that is, the water bodies in the first cavity 211 and the second cavity 215 do not flow. The first one-way conduction structure 24, the first water passage 212, and the second water passage 216 cooperate with each other to form a water passage connecting the first cavity 211 and the second cavity 215 in the filtering device 1. This water passage uses one of the first water passage 212 and the second water passage 216 to enter water and the other to discharge water, so that the filtering device 1 can output mineralized water flowing through the mineralization filter material 3 to the outside through this water passage.

[0037] For example, in Figure 2 in, Figure 2 the water passage flowing through the first cavity 211 and the second cavity 215 is shown by a dotted line with an arrow. The water body is input into the first cavity 211 from the first water passage 212, and then enters the second cavity 215 through the first one-way conduction structure 24 under the water flow pressure of the water passage and is output from the second water passage 216 of the filtering device 1. The mineralization filter material 3 is located in the second cavity 215. At this time, since the water body first flows into the first cavity 211 and then into the second cavity 215, when the filtering device 1 is in an immersed state, there is no water flow pressure in the water passage, the first one-way conduction structure 24 remains closed, the first cavity 211 and the second cavity 215 are relatively isolated, and the water body in the first cavity 211 does not contain minerals released by the mineralization filter material 3.

[0038] Refer to Figure 3 、 Figure 4 in, Figure 3 、 Figure 4 the water passage flowing through the first cavity 211 and the second cavity 215 is shown by a dotted line with an arrow. In Figure 3In the [device], water enters the first cavity 211 from the first waterway 212, and then passes through the first one-way conduction structure 24 under the water flow pressure to enter the second cavity 215 and is output from the second waterway 216 of the filtration device 1. The mineralized filter material 3 is located in the first cavity 211. At this time, since the water first flows into the first cavity 211 and then into the second cavity 215, the water in the second cavity 215 will contain the minerals released by the mineralized filter material 3. However, due to the existence of the first one-way conduction structure 24, the water in the second cavity 215 will not continuously soak the mineralized filter material 3. Therefore, when the filtration device 1 is in the soaking state, the mineral content of the water in the second cavity 215 will not continue to increase, that is, the mineral content of the second cavity 215 will remain at a relatively low level. Even if the mineral content of the water in the first cavity 211 is high, when the filtration device 1 discharges water next time, the water in the first cavity 211 is mixed with the water in the second cavity 215, which can effectively reduce the overall mineral content of the water output by the filtration device 1.

[0039] In Figure 4 the [device], water enters the second cavity 215 from the second waterway 216, and then passes through the first one-way conduction structure 24 to enter the first cavity 211 and is output from the first waterway 212 of the filtration device 1. The mineralized filter material 3 is located in the second cavity 215. At this time, since the water first flows into the second cavity 215 and then into the first cavity 211, the water in the first cavity 211 will contain the minerals released by the mineralized filter material 3. However, due to the existence of the first one-way conduction structure 24, the water in the first cavity 211 will not continuously soak the mineralized filter material 3. Therefore, when the filtration device 1 is in the soaking state, the mineral content of the water in the first cavity 211 will not continue to increase, that is, the mineral content of the water in the first cavity 211 will remain at a relatively low level. Even if the mineral content of the water in the second cavity 215 is high, when the filtration device 1 discharges water next time, the water in the second cavity 215 is mixed with the water in the first cavity 211, which can effectively reduce the overall mineral content of the water output by the filtration device 1.

[0040] The number of the first one-way conduction structures 24 can be one or more than two. One first one-way conduction structure 24 can meet the requirement of selectively connecting the first cavity 211 and the second cavity 215. As Figure 2 、 Figure 3 、 Figure 4 shown, the number of the first one-way conduction structures 24 can specifically be two, and the two first one-way conduction structures 24 can be simultaneously opened under the action of the one-way water pressure, so as to connect the first cavity 211 and the second cavity 215, enabling the water body to flow uniformly between the first cavity 211 and the second cavity 215 through the first one-way conduction structure 24.

[0041] Further, a first one-way conduction structure 24 can be arranged along the central axis of the filtration device 1, and more than two first one-way conduction structures 24 can be symmetrically arranged relative to the central axis of the filtration device 1. When flowing between the first cavity 211 and the second cavity 215 through the first one-way conduction structure 24, the water flow is made more uniform and stable, which can improve the structural stability of the filtration device 1.

[0042] In the structure provided by this specific embodiment, by forming a first cavity 211 and a second cavity 215 in the rear housing 21 that can be selectively connected only through the first one-way conduction structure 24, and utilizing the property that the first one-way conduction structure 24 can be opened only under the action of a one-way water flow to connect the first cavity 211 and the second cavity 215, the mineralized filter material 3 is only arranged in one of the first cavity 211 and the second cavity 215. When the filtration device 1 is in an immersion state without water flow, the mineralized filter material 3 can only contact and release minerals with the water body in one of the first cavity 211 and the second cavity 215, that is, only contact and release minerals with a part of the water body entering the filtration device 1, and the total amount of minerals released by the filtration device 1 during the immersion process can be reduced by reducing the volume of the water body in contact with the mineralized filter material 3.

[0043] When the filtration device 1 finishes the immersion process and outputs the water body, the one of the first cavity 211 and the second cavity 215 where the mineralized filter material 3 is provided will output the water body with a higher mineral concentration, and the water body output from the other one without the mineralized filter material 3 will have a lower mineral content or even no minerals released by the mineralized filter material 3. The two water bodies with different mineral concentrations are mixed. Even if the mineral concentration of the water body output from the one of the first cavity 211 and the second cavity 215 where the mineralized filter material 3 is provided reaches saturation, the mineral concentration of the water body finally output by the filtration device 1 can still be moderate, so as to effectively control the mineral content of the mineralized water output by the filtration device 1 and solve the problem that the mineral content in the water body is easy to exceed the standard when the mineralized filter material 3 is immersed to a certain extent.

[0044] As Figures 2 to 4 shown, in a specific embodiment of the present application, the first cavity 211 and the second cavity 215 can be arranged along the axial direction X of the filter element main body 2. Specifically, when the filtration device 1 is installed and put into use, the second cavity 215 can be located above the first cavity 211. The filter element main body 2 can include a first central tube 217, and the rear housing 21 can be provided with a first interface 213. One end of the first central tube 217 communicates with the second cavity 215, and the other end passes through the first interface 213. A first water passage 212 is formed between the inner wall of the first interface 213 and the outer wall of the first central tube 217, and a second water passage 216 is formed inside the first central tube 217.

[0045] In the structure provided in this specific embodiment, the first central tube 217 inserted into the first cavity 211 forms a second water path 216 communicating with the second cavity 215. The first water path 212 communicating with the first cavity 211 is arranged outside the first central tube 217, and the second water path 216 communicating with the second cavity 215 is located inside the first central tube 217, preventing the first cavity 211 and the second cavity 215 from communicating through structures other than the first one-way conduction structure 24, forming a single and unique water path in the rear housing 21, and effectively controlling the content of minerals in the mineralized water output after the filtration device 1 is soaked.

[0046] Continue to refer to Figure 5 、 Figure 6 , Figure 5 is Figure 1 the schematic cross-sectional structure diagram of the cross-section shown as B-B in Figure 6 is Figure 5 the enlarged structure diagram of area D in Figure 5 、 Figure 6 In

[0047] The filter element main body 2 further includes a front housing 22. The front housing 22 is provided with a front cavity 223, a front water inlet path 224 communicating with the front cavity 223, and a front water outlet path 225 communicating with the front cavity 223. The front filter material 5 is arranged in the front cavity 223. The front water inlet path 224 is used to connect the water inlet end 51 of the front filter material 5 and the water inlet pipe, and the front water outlet path 225 is used to connect the water outlet end 52 of the front filter material 5 and the water outlet pipe. The rear housing 21 is sleeved in the front cavity 223. The front cavity 223 is formed between the inner wall of the front housing 22 and the outer wall of the rear housing 21, and the front cavity 223 is isolated from the first cavity 211 and the second cavity 215.

[0048] Among them, the water inlet pipe can be connected to a water source. The water inlet pipe is used to input water into the front cavity 223, and the water outlet pipe is used to output the water in the front cavity 223. During actual use, the water inlet pipe and the water outlet pipe can be connected to the body of the device docked with the filtration device 1, and this device can be a mineral water mineralization device such as a mineralized water purifier.

[0049] In the structure provided by this specific embodiment, the filtering device 1 is further provided with a pre-chamber 223 isolated from the first chamber 211 and the second chamber 215. A pre-filter material 5 is arranged inside the pre-chamber 223. Through the cooperation of the pre-inlet water path 224 and the pre-outlet water path 225, the pre-filter material 5 can be used to filter the water body entering the pre-chamber 223 from the water inlet pipe. Thus, the filtering device 1 can not only use the first chamber 211 and the second chamber 215 to prepare mineralized water with a proper mineral content, but also output the water body filtered by the pre-filter material 5 through the water outlet pipe.

[0050] Further, when the filtering device 1 is docked with the water outlet pipe, one end of the water outlet pipe far from the pre-outlet water path 225 can be connected to one of the first water path 212 and the second water path 216, so as to input the water body filtered by the pre-filter material 5 into the first chamber 211 or the second chamber 215, and use the water body filtered by the pre-filter material 5 to prepare mineralized water with better quality.

[0051] Optionally, when the filtering device 1 is docked with the water outlet pipe, one end of the water outlet pipe far from the pre-outlet water path 225 can be connected to the water input end of the reverse osmosis filter material. The pure water outlet end 52 of the reverse osmosis filter material is connected to one of the first water path 212 and the second water path 216. Thus, the reverse osmosis filter material is used to further filter the water body filtered by the pre-filter material 5. The water body double-filtered by the pre-filter material 5 and the reverse osmosis filter material is then used to contact the mineralization filter material 3 to prepare mineralized water, so that the filtering device 1 can output mineralized water with better quality.

[0052] Optionally, the pre-filter material 5 can include at least one of a PP cotton filter material (polypropylene meltblown filter material) and an activated carbon filter material, which can filter out impurities such as pigments, odor molecules, solid particles, and oils in the water body, thereby improving the water quality of the water body.

[0053] Refer to Figures 2 to 4 , in a specific embodiment of the present application, the pre-housing 22 can also be provided with a second interface 221 and a third interface 222.

[0054] The filter element main body 2 may specifically include a partition 23 disposed within the rear housing 21, with a first cavity 211 and a second cavity 215 located on both sides of the partition 23. One end of the first central tube 217 communicating with the second cavity 215 is sealingly connected to the partition 23, and the end of the first central tube 217 away from the partition 23 is sealingly connected to the front housing 22. The second water path 216 within the first central tube 217 communicates with the second interface 221 at the end away from the second cavity 215. The filter element main body 2 further includes a second central tube 214 sleeved outside the first central tube 217, and a first water path 212 is also formed between the inner wall of the second central tube 214 and the outer wall of the first central tube 217. One end of the second central tube 214 is sealingly connected to the rear housing 21, and the other end of the second central tube 214 is sealingly connected to the front housing 22. The other end of the first water path 212 away from the first interface 213 communicates with the third interface 222.

Further, the partition 23 may be connected to the rear housing 21 to realize the relative fixation of the partition 23 and the rear housing 21, thereby reducing the probability of the partition 23 shaking within the rear housing 21 under the impact of water flow and enhancing the structural stability of the filtering device 1.

[0057] Refer to Figure 5 、 Figure 6 In a specific embodiment of the present application, the front cavity 223 may specifically be located between the outer wall of the second central tube 214 and the inner wall of the front housing 22.

[0060] Optionally, the first central tube 217 may not be sleeved inside the second central tube 214, but may be arranged relatively independently of the second central tube 214. The first central channel 217a is arranged inside the first central tube 217, and the second central channel 214a is arranged inside the second central tube 214. The first central channel 217a connects the second cavity 215 and the second interface 221, and the second central channel 214a connects the first interface 213 and the third interface 222. For this case, the front cavity 223 may be located between the outer peripheral surface of the first central tube 217, the outer peripheral surface of the second central tube 214 and the inner wall of the front housing 22.

[0061] Specifically, the spacer 23 may be provided with a first socket portion 231, and the filtering device 1 may further include a second socket member 72 arranged inside the front housing 22. One end of the first central tube 217 connecting the second cavity 215 is sleeved inside the first socket portion 231, the other end of the first central tube 217 is sleeved inside the second socket member 72, and the second socket member 72 is fixedly sleeved with the front housing 22, thereby isolating the first central channel 217a inside the first central tube 217 from the front cavity 223 and realizing the connection between the first central channel 217a and the second cavity 215 and the second interface 221.

[0062] The separator 23 may be provided with a fourth central tube 232, and a fourth central channel 232a is formed in the fourth central tube 232. One end of the fourth central tube 232 is disposed on the side of the separator 23 facing the inside of the second cavity 215, and the other end extends into the second cavity 215. A part of the second waterway 216 is formed in the fourth central channel 232a. The first socket part 231 is fixedly sleeved with the first central tube 217. The second waterway 216 in the first central channel 217a and the fourth central channel 232a is communicated through the first socket part 231.

[0063] Optionally, filter materials such as the mineralization filter material 3 disposed in the second cavity 215 may be sleeved on the outer periphery of the fourth central tube 232 and abut against the separator 23 and the inner wall of the second cavity 215 on the side away from the separator 23. The water body entering the second cavity 215 through the fourth central channel 232a must pass through the filtration of filter materials such as the mineralization filter material 3 before it can enter the first cavity 211 through the first one-way conduction structure 24. Or the water body entering the second cavity 215 from the first cavity 211 through the first one-way conduction structure 24 must pass through the filtration of filter materials such as the mineralization filter material 3 before it can flow to the second interface 221 through the fourth central channel 232a.

[0064] Optionally, the rear housing 21 may be provided with a second socket part 218, and the filtering device 1 may further include a first socket part 71. The second socket part 218 is fixedly sleeved with one end of the second central tube 214 communicating with the first interface 213, the other end of the second central tube 214 is sleeved in the first socket part 71, and the first socket part 71 is fixedly sleeved with the housing, so as to isolate the second central channel 214a in the second central tube 214 from the front cavity 223 and the first central channel 217a, and realize the communication between the second central channel 214a and the first interface 213 and the third interface 222.

[0065] Optionally, as Figure 3 shown, the filtering device 1 may further include a third socket part 73. The third socket part 73 is provided with a socket hole, and the first central tube 217 passes through the socket hole and is fixedly and sealingly connected with the third socket part 73. When filter materials such as the mineralization filter material 3 are disposed in the first cavity 211, one end of the filter materials such as the mineralization filter material 3 may abut against one side of the separator 23, and the other end of the filter materials such as the mineralization filter material 3 may abut against the third socket part 73. The water body input into the first cavity 211 must flow through the filter materials such as the mineralization filter material 3 therein before it can be output to the outside through the first waterway 212 or enter the second cavity 215 through the first one-way conduction structure 24.

[0066] Further, referring to Figure 6The filter device 1 may further include a third central tube 6, which may be sleeved on the outer periphery of the second central tube 214. A third central channel 61 is formed between the inner wall of the third central tube 6 and the outer wall of the first central tube 217, and one end of the third central channel 61 is connected to the water inlet end 51 of the pre-filter material 5. The third central tube 6 is also provided with a third sleeve portion 62, which is sleeved and fixed with the outer shell, and the third sleeve portion 62 is connected to the third central channel 61 and the pre-water inlet 224, so as to realize the connection between the water inlet end 51 of the pre-filter material 5 and the pre-water inlet 224.

[0067] Optionally, one end of the pre-filter material 5 abuts against the rear shell body 21, and the other end of the pre-filter material 5 abuts against the side of the third center tube 6 facing away from the third sleeve portion 62. Water input into the pre-cavity 223 from the pre-inlet waterway 224 must flow through the pre-filter material 5 from the water inlet end 51 of the pre-filter material 5 before it can be input into the pre-outlet waterway 225 through the water outlet end 52 of the pre-filter material 5.

[0068] See also Figure 2 In a specific embodiment of the present application, the first one-way conducting structure 24 may include a one-way valve 26. Specifically, the first one-way conducting structure 24 may include an opening corresponding to the one-way valve 26 disposed on the isolation member 23, and the one-way valve 26 may be opened under the action of a one-way water flow, for example, the one-way valve 26 may be a duckbill valve.

[0069] When there is water flow in the reverse direction of the one-way valve 26 or when there is no water flow (i.e., water soaks the mineralized filter material 3), the one-way valve 26 is located in the opening and blocks the opening, thereby keeping the first one-way conducting structure 24 closed, and the water cannot flow freely between the first cavity 211 and the second cavity 215 through the opening. When there is water flow in the forward direction of the one-way valve 26, the one-way valve 26 can be moved out of the opening under the pressure of the water flow, thereby opening the first one-way conducting structure 24, allowing the water to flow between the first cavity 211 and the second cavity 215 through the opening.

[0070] Optionally, see Figure 3 The first one-way conductive structure 24 may include a magnetic attraction component 27, and the magnetic attraction component 27 includes a first magnetic member 271 and a second magnetic member 272. The first magnetic member 271 and the second magnetic member 272 have opposite polarities, and the first magnetic member 271 is used to separate from the second magnetic member 272 under the action of unidirectional water pressure to open the first one-way conductive structure 24.

[0071] Specifically, the second magnetic member 272 can be disposed on the isolation member 23, and the second magnetic member 272 can be provided with an opening communicating the first cavity 211 and the second cavity 215. The first magnetic member 271 is provided with an abutting top. When the first magnetic member 271 and the second magnetic member 272 are adsorbed, the abutting top is used to abut against the second magnetic member 272 on the periphery of the opening, thereby blocking the opening, keeping the first one-way conduction structure 24 closed, and preventing water from flowing between the first cavity 211 and the second cavity 215 through the opening. When water flows through, the water pressure pushes against the first magnetic member 271 to counteract the magnetic force, separating the first magnetic member 271 from the second magnetic member 272, and opening the opening, thereby opening the first one-way conduction structure 24 and enabling water to flow between the first cavity 211 and the second cavity 215 through the opening.

[0072] Optionally, referring to Figure 3 , the first one-way conduction structure 24 may include an elastic rubber valve 28 (which can be a duckbill valve) disposed on the isolation member 23. The elastic rubber valve 28 is provided with an elastic channel 281 that can be automatically closed under the action of an elastic restoring force. The elastic rubber valve 28 is used to deform under the action of a one-way water pressure to open the elastic channel 281.

[0073] Specifically, the elastic rubber valve 28 may be provided with a guiding surface on the side facing the water flow direction. The elastic channel 281 is disposed at the end of the guiding surface. The water flow impacts the elastic rubber valve 28 under the guiding action of the guiding surface, compressing the elastic rubber valve 28 on the periphery of the elastic channel 281, thereby opening the elastic channel 281 and using the elastic channel 281 to communicate the first cavity 211 and the second cavity 215.

[0074] Referring to Figures 2 to 4 , in a specific embodiment of the present application, the filter element main body 2 is further provided with a second one-way conduction structure 25.

[0075] Optionally, when the mineralization filter material 3 is located in the first cavity 211, the second one-way conduction structure 25 is used to open under the action of a one-way water pressure to communicate the first water path 212 and the first cavity 211. Thus, when there is no water flowing through, the first cavity 211 provided with the mineralization filter material 3 is isolated from the outside, preventing the mineralization filter material 3 from releasing minerals into the water outside the first cavity 211 through the first water path 212, and effectively controlling the total amount of minerals released by the filtering device 1, and to a certain extent solving the problem that the mineral content in the water is likely to exceed the standard when the mineralization filter material 3 is soaked. As Figure 3 shown, at this time, the second one-way conduction structure 25 can be disposed at the third interface 222.

[0076] Optionally, when the mineralized filter medium 3 is located in the second cavity 215, the second one-way conduction structure 25 is used to open under the action of the one-way water pressure to connect the second water path 216 and the second cavity 215. Thus, when there is no water flowing through, the second cavity 215 provided with the mineralized filter medium 3 is isolated from the outside, avoiding the release of minerals from the mineralized filter medium 3 into the water outside the second cavity 215 through the second interface 221, and effectively controlling the total amount of minerals released by the filtering device 1, and to a certain extent solving the problem that the mineral content in the water is likely to exceed the standard when the mineralized filter medium 3 is soaked. As Figure 4 shown, at this time, the second one-way conduction structure 25 can be arranged in the fourth central tube 232.

[0077] In a specific embodiment of the present application, the second one-way conduction structure 25 may include a one-way valve 26. Specifically, the first one-way conduction structure 24 may include an opening corresponding to the one-way valve 26, and the one-way valve 26 can be opened under the action of the one-way water flow. For example, the one-way valve 26 can be a duckbill valve.

[0078] Specifically, referring to Figure 3 , when the mineralized filter medium 3 is located in the first cavity 211, the second one-way conduction structure 25 can be located at the third interface 222, and the one-way valve 26 can move relative to the third interface 222 under the action of the water flow. When there is a water flow in the opposite direction of the one-way valve 26 or there is no water flow (i.e., the water body soaks the mineralized filter medium 3), the one-way valve 26 is located in the third interface 222 and blocks the third interface 222, so as to keep the second one-way conduction structure 25 closed, and the water body cannot flow into or out of the first cavity 211 through the third interface 222. When there is a water flow in the forward direction of the one-way valve 26, the one-way valve 26 can be moved out of the third interface 222 under the pressure brought by the water flow, so as to open the second one-way conduction structure 25, enabling the water body to flow into or out of the first cavity 211 through the first interface 213.

[0079] Specifically, referring to Figure 4 , when the mineralized filter medium 3 is located in the second cavity 215, the second one-way conduction structure 25 can be located in the fourth central tube 232, and the one-way valve 26 can be sleeved in the fourth central channel 232a and can move relative to the fourth central tube 232 under the action of the water flow. When there is a water flow in the opposite direction of the one-way valve 26 or there is no water flow (i.e., the water body soaks the mineralized filter medium 3), the one-way valve 26 is sleeved in the second central tube 214 and blocks the fourth central channel 232a, so as to keep the second one-way conduction structure 25 closed, and the water body cannot flow into or out of the second cavity 215 through the fourth central channel 232a. When there is a water flow in the forward direction of the one-way valve 26, the one-way valve 26 can be moved out of the fourth central channel 232a under the pressure brought by the water flow, so as to open the second one-way conduction structure 25, enabling the water body to flow into or out of the second cavity 215 through the fourth central channel 232a.

[0080] Optionally, referring to Figure 3 , the second one-way conduction structure 25 may also include a magnetic attraction component 27. The magnetic attraction component 27 may include a first magnetic member 271 and a second magnetic member 272. The first magnetic member 271 and the second magnetic member 272 have opposite polarities and can attract each other. The first magnetic member 271 is used to separate from the second magnetic member 272 under the action of unidirectional water pressure to open the second one-way conduction structure 25.

[0081] Specifically, when the mineralized filter medium 3 is located in the first cavity 211, the second magnetic member 272 may be disposed around the third interface 222. The first magnetic member 271 is provided with an abutting top. When the first magnetic member 271 and the second magnetic member 272 are attracted, the abutting top is used to abut against the second magnetic member 272 around the third interface 222, thereby blocking the third interface 222 and keeping the second one-way conduction structure 25 closed, so that water cannot flow into or out of the first cavity 211 through the third interface 222. When water flows through, the water pressure pushes against the magnetic force, causing the first magnetic member 271 to separate from the second magnetic member 272, and the third interface 222 is opened, thereby opening the second one-way conduction structure 25, so that water can flow into or out of the first cavity 211 through the third interface 222.

[0082] When the mineralized filter medium 3 is located in the second cavity 215, the second magnetic member 272 may be disposed on the fourth central tube 232. The first magnetic member 271 is provided with an abutting top. When the first magnetic member 271 and the second magnetic member 272 are attracted, the abutting top is used to abut against one end of the fourth central tube 232 communicating with the second cavity 215, thereby blocking the fourth central tube 232 and keeping the second one-way conduction structure 25 closed, so that water cannot flow into or out of the second cavity 215 through the second central tube 214. When water flows through, the water pressure pushes against the magnetic force, causing the first magnetic member 271 to separate from the second magnetic member 272, and the fourth central tube 232 communicates with the second cavity 215, thereby opening the second one-way conduction structure 25, so that water can flow into or out of the second cavity 215 through the second central tube 214.

[0083] Referring to Figure 3 , the second one-way conduction structure 25 may further include an elastic rubber valve 28. The elastic rubber valve 28 is provided with a closed elastic channel 281. The elastic rubber valve 28 is used to deform under the action of unidirectional water pressure to open the elastic channel 281.

[0084] Specifically, the elastic rubber valve 28 may be provided with a guiding surface on the side facing the water flow direction. The elastic channel 281 is disposed at the end of the guiding surface. The water flow impacts the elastic rubber valve 28 under the guiding action of the guiding surface, compressing the elastic rubber valve 28 around the elastic channel 281, thereby opening the elastic channel 281, and using the elastic channel 281 to enable water to flow into or out of one of the first cavity 211 and the second cavity 215.

[0085] As Figures 2 to 4 shown, in a specific embodiment of the present application, the filtration device 1 further includes a buffer filter medium 4, and the mineralization filter medium 3 is accommodated in one of the first cavity 211 and the second cavity 215, and the buffer filter medium 4 is accommodated in the other of the first cavity 211 and the second cavity 215.

[0086] Optionally, the buffer filter medium 4 may include at least one of a nanofiltration filter medium, an activated carbon filter medium, a zeolite filter medium, a bamboo charcoal filter medium, and a PP cotton filter medium (polypropylene meltblown filter medium), which can effectively filter out impurities such as pigments, odor molecules, solid particles, and oils in the water body, thereby improving the water quality of the water body.

[0087] Among them, the nanofiltration filter medium is a filter medium category between ultrafiltration and reverse osmosis innovatively invented by the cross-penetration of advanced nanotechnology and traditional filtration technology. Its separation performance depends on the nano-scale microporous structure in its active separation layer, and its separation mechanism follows the adsorption-dissolution-diffusion-filtration model. It can intercept those organic substances and heavy metals that can pass through ultrafiltration while allowing some minerals intercepted by reverse osmosis to pass through, enabling the processes of concentration and salt permeation to proceed simultaneously, thus meeting specific separation and purification requirements.

[0088] Referring to Figures 2 to 6 , one end of the buffer filter medium 4 can abut against the isolation member 23, and the other end of the buffer filter medium 4 abuts against the inner wall of the rear housing 21 or the third socket member 73. The water body input into one of the first cavity 211 and the second cavity 215 must pass through the buffer filter medium 4 before being output to the outside, or enter the other of the first cavity 211 and the second cavity 215 through the first one-way conduction structure 24 to contact the mineralization filter medium 3.

[0089] Optionally, when the first one-way conduction structure 24 is opened and the buffer filter medium 4 is located upstream of the mineralization filter medium 3, the buffer filter medium 4 may include an antagonistic filter medium for inhibiting the release of minerals from the mineralization filter medium 3 into the water body.

[0090] The antagonistic filter medium can dissolve antagonistic substances into the water body, and the antagonistic substances are used to inhibit the release of minerals from the mineralization filter medium 3 into the water body. When the water body is input into the filtration device 1, the water body first contacts the antagonistic filter medium and then contacts the mineralization filter medium 3. The antagonistic substances dissolved by the antagonistic filter medium contact the mineralization filter medium 3 along with the water body, thereby being able to inhibit the excessive dissolution of minerals in the mineralization filter medium 3, and further being able to control the mineral content in the mineralized water output by the filtration device 1 and reduce the probability of excessive mineral content in the mineralized water.

[0091] Exemplarily, the mineralized filter medium 3 can be a zinc mineralized filter medium or a copper mineralized filter medium, that is, the mineralized filter medium 3 contains zinc or / and copper. The antagonistic filter medium can be an alkaline filter medium. The water flow first contacts the alkaline filter medium and then contacts the mineralized filter medium 3. The alkaline substances dissolved into the water body by the alkaline filter medium can contact the mineralized filter medium 3 along with the water flow, thereby inhibiting the dissolution of zinc and copper elements in the mineralized filter medium 3 to a certain extent. Optionally, the antagonistic filter medium can include at least one of materials such as calcite, aragonite, magnesite, dolomite, etc. The mineralized filter medium 3 can include at least one of materials such as smithsonite, calamine, hydrozincite, etc.

[0092] Specifically, taking the mineralized filter medium 3 as a zinc mineralized filter medium as an example, the dissolution reaction of zinc element (zinc-containing filter body, such as smithsonite) in water is: ZnCO3 = Zn 2+ + CO3 2- . Under general conditions (for example, pure water obtained after RO membrane filtration), the saturated solubility of Zn 2+ when soaked in water can reach 6.0 mg / L, far exceeding the national standard limit of 1.0 mg / L. And when the water quality remains unchanged, Zn 2+ and CO3 2- are dissolved synchronously. Therefore, by controlling the concentration of CO3 2- at the lowest level, the saturated dissolution concentration of Zn 2+ can be controlled at the lowest level.

[0093] When the pH value of the water body is acidic, due to excessive H + and other ions in the system, the hydrolysis of H2CO3 to release H + is inhibited. As the pH value of the water body gradually increases, the H + and other ions in the system gradually decrease, and the inhibitory effect on the hydrolysis of H2CO3 gradually decreases. The H + ions are gradually hydrolyzed and released, and the H2CO3 in the water body is first converted into HCO 3- . As the pH value of the water body continues to increase, the H 3- ions in HCO + also begin to continue to be released, and HCO 3- is gradually converted into CO3 2- . It is not difficult to see that the content of CO3 2- in the water body has an obvious correlation with the pH value of the water body.

[0094] Optionally, when the first unidirectional conduction structure 24 is open and the buffer filter medium 4 is located downstream of the mineralization filter medium 3, the buffer filter medium 4 may include an adsorption filter medium for adsorbing minerals released by the mineralization filter medium 3 into the water body. When the filtering device 1 discharges water outward, the water body containing the minerals dissolved from the mineralization filter medium 3 still needs to contact the adsorption filter medium, so that the minerals in the water body can be partially adsorbed by the adsorption filter medium, which can reduce the mineral content in the mineralized water output by the filtering device 1 and reduce the probability of excessive mineral content in the mineralized water.

[0095] Exemplarily, the adsorption filter medium may include at least one of an ion exchange resin filter medium, a reverse osmosis filter medium, an activated alumina filter medium, a KDF (high-purity copper-zinc alloy) filter medium, and a zeolite filter medium.

[0096] The ion exchange resin filter medium can adsorb at least one of mineral elements such as calcium, magnesium, lead, and copper. The reverse osmosis filter medium can adsorb at least one of mineral elements such as calcium, magnesium, sodium, fluorine, arsenic, and nitrate. The activated alumina filter medium can be used to adsorb fluoride, arsenic, and sulfide. The KDF (high-purity copper-zinc alloy) filter medium can be used to adsorb lead, mercury, chlorine, hydrogen sulfide, and some calcium and magnesium minerals. The zeolite filter medium can be used to adsorb ammonia nitrogen, some heavy metals, and radioactive substances.

[0097] The specific embodiment of the present application may further provide a mineral water mineralization device, including a water outlet component and the filtering device 1 described in any one of the above specific embodiments. The water outlet component is provided with a mineralized water outlet, and the mineralized water outlet is communicated with the first cavity 211 or the second cavity 215 of the filtering device 1, so that the mineralized water in the filtering device 1 can be output through the mineralized water outlet of the water outlet component, and then can be supplied for users to use.

[0098] Furthermore, the mineral water mineralization device may further be provided with a mineralization water inlet, and the mineralization water inlet is communicated with the other one of the first cavity 211 and the second cavity 215, so that the external water body can enter the first cavity 211 and the second cavity 215 through the mineralization water inlet, thereby preparing mineralized water by using the mineralization filter medium 3 and outputting it through the mineralized water outlet.

[0099] In the structure provided by this specific embodiment, by forming a first cavity 211 and a second cavity 215 in the rear housing 21 that can only be selectively communicated through the first one-way conduction structure 24, and utilizing the property that the first one-way conduction structure 24 can only be opened under the action of unidirectional water flow to communicate the first cavity 211 and the second cavity 215, the mineralization filter material 3 is only arranged in one of the first cavity 211 and the second cavity 215. When the filtration device 1 is in an immersion state without water flow, the mineralization filter material 3 can only contact the water body in one of the first cavity 211 and the second cavity 215 and release minerals, that is, only contact a part of the water body entering the filtration device 1 and release minerals, and the total amount of minerals released by the filtration device 1 during the immersion process can be reduced by reducing the volume of the water body contacting the mineralization filter material 3.

[0100] When the filtration device 1 finishes the immersion process and outputs the water body, the cavity among the first cavity 211 and the second cavity 215 where the mineralization filter material 3 is provided will output the water body with a higher mineral concentration, while the water body output from the other cavity without the mineralization filter material 3 has a lower mineral content or even does not contain the minerals released by the mineralization filter material 3. The two water bodies with different mineral concentrations are mixed. Even if the mineral concentration of the water body output from the cavity among the first cavity 211 and the second cavity 215 where the mineralization filter material 3 is provided reaches saturation, the mineral concentration of the water body finally output by the filtration device 1 can still be moderate, so as to effectively control the mineral content in the mineralized water output by the filtration device 1 and solve the problem that the mineral content in the water body is prone to exceed the standard when the mineralization filter material 3 is immersed to a certain extent.
