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

[0003] At present, mineralized water is usually prepared by using a mineralization filter element. The mineral salts in the mineralization filter element can be released into the water body during the process of water flowing through or soaking the mineralization filter element, so that the water body is transformed into mineralized water. However, it is difficult to effectively control the mineral content in the mineralized water prepared by this method. Especially when the mineralization filter element is soaked in the water body, due to the long contact time between the mineralization filter element and the water body, and since the mineralization filter material of the mineralization filter element is arranged in the shell, the water stored in the shell is all used to soak the mineralization filter material, the minerals in the water body are extremely easy 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 have a negative impact on users. Summary of the Utility Model

Therefore, it should not be construed as a limitation to the present invention. In the description of the present invention, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0029] In the various specific technical features and embodiments described in the specific implementation manners, without contradiction, they can be combined in any suitable manner. For example, different embodiments can be formed by combining different specific technical features / embodiments. To avoid unnecessary repetition, various possible combination methods of the specific technical features / embodiments in the present invention will not be described separately.

[0030] 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 mineral salts, rich in essential macroelements and trace elements for the human body. Therefore, mineralized water is favored as drinking water. At the same time, in production and experiments, there is also a certain demand for mineralized water containing specific mineral salts.

[0031] Currently, mineralized water is usually prepared by using a mineralization filter element. The mineral salts in the mineralization filter element can be released into the water body during the process of water flowing through or soaking the mineralization filter element, converting the water body into mineralized water. However, it is difficult to effectively control the mineral content in the mineralized water prepared by this method. Especially when the mineralization filter element is soaked in the water body, since the contact time between the mineralization filter element and the water body is relatively long, and since the mineralization filter material of the mineralization filter element is arranged in the shell, the water stored in the shell is all used to soak the mineralization filter material, 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 have a negative impact on users.

[0032] To solve this problem, the present invention proposes a filtering device.

[0033] Such asFigures 1 to 3 As shown, the filtering device 100 provided by the present utility model includes a housing 10 and a first filter element assembly 30 disposed within the housing 10. A mineralization chamber 31 and an adjustment chamber 32 are provided within the first filter element assembly 30. A mineralization filter element 36 is provided within the mineralization chamber 31. A first one-way conduction structure 381 and a second one-way conduction structure 382 are provided between the mineralization chamber 31 and the adjustment chamber 32. The first one-way conduction structure 381 and the second one-way conduction structure 382 are configured to open under the action of a one-way water pressure to conduct the mineralization chamber 31 and the adjustment chamber 32, and the conduction water flow direction of the first one-way conduction structure 381 is opposite to the conduction water flow direction of the second one-way conduction structure 382.

[0034] The first one-way conduction structure 381 and the second one-way conduction structure 382 may include check valves. Specifically, the first one-way conduction structure 381 and the second one-way conduction structure 382 may include openings corresponding to the check valves. The check valves can be opened under the action of a one-way water flow. For example, the check valve can be a duckbill valve. When there is a water flow in the opposite direction of the check valve or no water flow exists, the check valve is in a closed state, and the water body cannot freely flow between the mineralization chamber 31 and the adjustment chamber 32. When there is a water flow in the forward direction of the check valve, the check valve can be opened under the pressure brought by the water flow, so that the water body can freely flow between the mineralization chamber 31 and the adjustment chamber 32.

[0035] When there is no water flow pressure, both the first one-way conduction structure 381 and the second one-way conduction structure 382 remain closed, and the mineralization chamber 31 and the adjustment chamber 32 are relatively isolated, and the water bodies in the mineralization chamber 31 and the adjustment chamber 32 do not flow through. When the filtering device 100 is in the mineralization soaking process, in the case of no water flow pressure, the mineralization filter element 36 can only contact the water body in the mineralization chamber 31 and precipitate minerals. The water body in the adjustment chamber 32 without the mineralization filter element 36 has a lower mineral content or even no minerals. When the filtering device 100 finishes the soaking process and outputs the water body, one of the first one-way conduction structure 381 and the second one-way conduction structure 382 is opened under the action of the water flow to connect the mineralization chamber 31 and the adjustment chamber 32. The water body with a high mineral content in the mineralization chamber 31 is mixed with the water body with a low mineral content in the adjustment chamber 32, which can make the concentration of minerals in the water body output by the filtering device 100 moderate, thereby effectively controlling the mineral content in the mineralized water and solving to a certain extent the problem that the mineral content in the water body is prone to exceed the standard when the mineralization filter element 36 is soaked.

[0036] The mineralization filter element 36 in the mineralization cavity 31 is used for mineralizing the water body. The material of the mineralization filter element 36 includes mineral materials. For example, the material of the mineralization filter element 36 can be natural rock materials, such as magnesite (containing magnesium element), celestite (containing strontium element), selenium ore (containing selenium element), medical stone (containing elements such as calcium, magnesium, potassium, sodium, etc.). Or, the material of the mineralization filter element 36 can be composed of a mixture of various rock materials. Or, the material of the mineralization filter element 36 can be a modified material rich in various mineral elements obtained by artificial modification, as long as it can precipitate minerals beneficial to the human body into the water body. The material of the mineralization filter element 36 can also include polypropylene and activated carbon, so that the mineralization filter element 36 can filter the water body while mineralizing the water body.

[0037] In this technical solution, the first one-way conduction structure 381 and the second one-way conduction structure 382 can also include a magnetic attraction component. The magnetic attraction component includes a first magnetic member and a second magnetic member. The polarities of the opposite sides of the first magnetic member and the second magnetic member are opposite. The first magnetic member is used to separate from the second magnetic member under the action of unidirectional water pressure to open the corresponding one-way conduction structure.

[0038] The first one-way conduction structure 381 and the second one-way conduction structure 382 can also include an elastic rubber valve. The elastic rubber valve is provided with an elastic channel that can be automatically closed under the action of an elastic restoring force. The elastic rubber valve is used to deform under the action of unidirectional water pressure to open the elastic channel. Specifically, the elastic rubber valve can be provided with a guiding surface on the side facing the water flow direction, and the elastic channel is arranged at the end of the guiding surface. The water flow impacts the elastic rubber valve under the guiding action of the guiding surface, compressing the elastic rubber valve on the periphery of the elastic channel, so as to open the elastic channel, and the mineralization cavity 31 and the adjustment cavity 32 are connected by using the elastic channel.

[0039] The water flow conduction direction of the first one-way conduction structure 381 is opposite to that of the second one-way conduction structure 382. For example, if the water flow conduction direction of the first one-way conduction structure 381 is from the adjustment cavity 32 to the mineralization cavity 31, then the water flow conduction direction of the second one-way conduction structure 382 is from the mineralization cavity 31 to the adjustment cavity 32. Or, if the water flow conduction direction of the first one-way conduction structure 381 is from the mineralization cavity 31 to the adjustment cavity 32, then the water flow conduction direction of the second one-way conduction structure 382 is from the adjustment cavity 32 to the mineralization cavity 31.

[0040] The filtration device 100 further includes a first water inlet pipe 61 and a first water outlet pipe 62. One of the first water inlet pipe 61 and the first water outlet pipe 62 is communicatively connected to the mineralization chamber 31, and the other is communicatively connected to the adjustment chamber 32. The first water inlet pipe 61 is used to supply water to the first filter element assembly 30, and the first water outlet pipe 62 is used to discharge the water in the first filter element assembly 30. The water flow directions of the first one-way conduction structure 381 and the second one-way conduction structure 382 are opposite. This design enables the filtration device 100 to flexibly change the water inlet direction and the water outlet direction according to the actual usage situation, so that the filtration device 100 can better adapt to different installation environments and usage scenarios.

[0041] For example, the first water inlet pipe 61 can be communicatively connected to the mineralization chamber 31, and the first water outlet pipe 62 can be communicatively connected to the adjustment chamber 32. At this time, the filtration device 100 takes in water from the mineralization chamber 31 and discharges water from the adjustment chamber 32. The first one-way conduction structure 381 can be opened under the action of the water flow. The water flow flows from the mineralization chamber 31 to the adjustment chamber 32 and is finally discharged outward from the first water outlet pipe 62. Or, the first water inlet pipe 61 can be communicatively connected to the adjustment chamber 32, and the first water outlet pipe 62 can be communicatively connected to the mineralization chamber 31. At this time, the filtration device 100 takes in water from the adjustment chamber 32 and discharges water from the mineralization chamber 31. The second one-way conduction structure 382 can be opened under the action of the water flow. The water flow flows from the adjustment chamber 32 to the mineralization chamber 31 and is finally discharged outward from the first water outlet pipe 62.

[0042] During actual use, the first water inlet pipe 61 and the first water outlet pipe 62 can be connected to the body of the docking device of the filtration device 100, and this device can be a mineral spring mineralization device such as a mineralized water purifier.

[0043] In some embodiments of the filtration device 100, the first filter element assembly 30 may further include a post-filter 37, and the post-filter 37 is disposed in the adjustment chamber 32.

[0044] The post-filter 37 can be made of nano materials such as nano fibers, nano ceramics, and nano activated carbon. These materials have nano-scale pores, a high specific surface area, and high adsorption performance, and can effectively remove nano-scale particulate matters such as bacteria, viruses, and organic matters, so as to be able to filter the water body again. Or, antibacterial materials such as nano silver can be added to the post-filter 37 to inhibit the growth of bacteria. Or, charge fibers can be added to the post-filter 37. The charge fibers have charge characteristics and a nano-scale pore structure, and can remove tiny particles, bacteria, viruses, and organic matters in water through electrostatic adsorption. Industrially, the surface of the fiber can be modified by chemical methods to introduce charged groups, thereby endowing the fiber with charge characteristics.

[0045] A post-filter 37 is arranged in the adjustment cavity 32, which enables the adjustment cavity 32 to not only have the function of adjusting the mineralization concentration of water, but also increase the filtration level of the filtration device 100, so that while adjusting the mineralization concentration of water, the adjustment cavity 32 can also purify the water and improve the quality of the water.

[0046] The first filter element assembly 30 may include a first filter element cylinder body 34, the first filter element cylinder body 34 is arranged in the housing 10, and a partition 35 is arranged in the first filter element cylinder body 34 to divide the cavity of the first filter element cylinder body 34 into a mineralization cavity 31 and an adjustment cavity 32. The mineralization cavity 31 and the adjustment cavity 32 are coaxially arranged up and down. A mineralization filter element 36 is arranged in the mineralization cavity 31, and a post-filter 37 is arranged in the adjustment cavity 32. The first one-way conduction structure 381 and the second one-way conduction structure 382 are both arranged on the partition 35.

[0047] Specifically refer to Figures 1 to 3 As shown in the figure, the post-filter 37 axially forms a first hollow channel 371 that runs through, and the outer peripheral wall of the post-filter 37 is spaced from the inner peripheral wall of the first filter element cylinder body 34 to form a first water passing gap 372. That is, the post-filter 37 divides the adjustment cavity 32 into a first hollow channel 371 and a first water passing gap 372.

[0048] The mineralization filter element 36 axially forms a second hollow channel 361 that runs through, and the outer peripheral wall of the mineralization filter element 36 is spaced from the inner peripheral wall of the first filter element cylinder body 34 to form a second water passing gap 362. That is, the mineralization filter element 36 divides the mineralization cavity 31 into a second hollow channel 361 and a second water passing gap 362. The second water passing gap 362 is communicated with the first hollow channel 371 through the first one-way conduction structure 381 or the second one-way conduction structure 382. One of the first water inlet pipe 61 and the first water outlet pipe 62 is communicated with the first water passing gap 372, and the other is communicated with the second hollow channel 361.

[0049] Refer to Figure 3 As shown in the figure, the first filter element assembly 30 further includes a first end cover 40. The first filter element cylinder body 34 has a first end wall 341 and a second end wall 342 that are oppositely arranged. The first end cover 40 is arranged in the adjustment cavity 32 and is spaced from the first end wall 341. The post-filter 37 is clamped between the first end cover 40 and the partition 35. A first water passing cavity 41 is formed between the first end cover 40 and the first end wall 341, and the first water passing cavity 41 is communicated with the first water passing gap 372. One of the first water inlet pipe 61 and the first water outlet pipe 62 is communicated with the first water passing cavity 41.

[0050] The post-filter element also includes a second end cover 42, which is arranged in the mineralization cavity 31 and spaced apart from the partition 35. The mineralization filter element 36 is sandwiched between the second end cover 42 and the second end wall 342. A second water passage cavity 43 is formed between the second end cover 42 and the partition 35. The second water passage cavity 43 is connected to the second water passage gap 362 and the first hollow channel 371 through the first unidirectional conductive structure 381 or the second unidirectional conductive structure 382.

[0051] Figure 4 The dotted line with an arrow shows the flow path of the filter device 100, where water enters the regulating chamber 32 and flows out of the mineralization chamber 31. At this time, the water flow path of the filter device 100 is as follows: the filter device 100 delivers water to the first water passage chamber 41 through the first water inlet pipe 61, the water in the first water passage chamber 41 flows into the first water passage gap 372, the water in the first water passage gap 372 flows into the first hollow channel 371 through the pores of the post filter element 37, and when the water flows between the pores of the post filter element 37, the post filter element 37 can adsorb and intercept impurities in the water. One of the first one-way conducting structure 381 and the second one-way conducting structure 382 is opened under the action of water flow pressure to connect the first hollow channel 371 and the second water passage chamber 43. The water in the first hollow channel 371 flows into the second water passage chamber 43 through the opened one-way conducting structure, and the water in the second water passage chamber 43 flows into the second water passage gap 362. The water in the second water passage gap 362 passes through the pores of the mineralized filter element 36 and enters the second hollow channel 361. When the water flows between the pores of the mineralized filter element 36, the mineralized filter element 36 can adsorb and intercept impurities in the water body, and the minerals on the mineralized filter element 36 will precipitate. In this process, the water body with high mineral content in the mineralized chamber 31 and the water body with low mineral content in the regulating chamber 32 are mixed with each other, so as to obtain water with moderate mineral concentration. Finally, the water in the second hollow channel 361 is discharged outward through the first outlet pipe 62. The flow path at this time is a positive flow path.

[0052] Figure 5The flow path in which the filtering device 100 takes in water from the mineralization chamber 31 and discharges water from the adjustment chamber 32 is shown by a dotted line with an arrow. At this time, the water flow path of the filtering device 100 is as follows: The filtering device 100 sends water to the second hollow channel 361 through the first water outlet pipe 62. The water in the second hollow channel 361 passes through the pores of the mineralization filter element 36 and enters the second water passing gap 362. When the water flows through the pores of the mineralization filter element 36, the mineralization filter element 36 can adsorb and intercept impurities in the water body, and at the same time, minerals on the mineralization filter element 36 will precipitate. The water in the second water passing gap 362 flows into the second water passing chamber 43. One of the first one-way conduction structure 381 and the second one-way conduction structure 382 is opened under the action of water flow pressure to connect the second water passing chamber 43 and the first hollow channel 371. The water in the second water passing chamber 43 flows into the first hollow channel 371 through the opened one-way conduction structure. The water in the first hollow channel 371 passes through the pores of the post-filter element 37 and flows into the first water passing gap 372. When the water flows through the pores of the post-filter element 37, the post-filter element 37 can adsorb and intercept impurities in the water body. During this process, the water body with a high mineral content in the mineralization chamber 31 and the water body with a low mineral content in the adjustment chamber 32 are mixed with each other, so as to obtain water with a moderate concentration of minerals. Then, the water in the first water passing gap 372 flows into the first water passing chamber 41 and is finally discharged outwards through the first water inlet pipe 61. The flow path at this time is a reverse flow path.

[0053] A water stop valve 39 can be arranged in the first water outlet pipe 62. As Figure 3 shown, the water stop valve 39 is used to control the conduction or blockage of the first water outlet pipe 62, so as to control whether the water in the first filter element assembly 30 is discharged or whether water is sent to the first filter element assembly 30.

[0054] In the above-described embodiments, the adjustment chamber 32 and the mineralization chamber 31 are coaxially arranged in the up-down direction. Of course, in some embodiments of the filtering device 100, the adjustment chamber 32 and the mineralization chamber 31 can be arranged inside and outside. For example, the adjustment chamber 32 can be arranged around the mineralization chamber 31, that is, the housing of the adjustment chamber 32 is sleeved on the housing of the mineralization chamber 31, and the adjustment chamber 32 and the mineralization chamber 31 are concentrically arranged. Or, the mineralization chamber 31 can be arranged around the adjustment chamber 32, that is, the housing of the mineralization chamber 31 is sleeved on the housing of the adjustment chamber 32, and the adjustment chamber 32 and the mineralization chamber 31 are concentrically arranged.

[0055] Refer to Figure 1 and Figure 2, in some embodiments of the filtration device 100, it further includes a second filter element assembly 20. The second filter element assembly 20 is disposed within the housing 10. A pre-filter chamber 22 is provided between the second filter element assembly 20 and the housing 10, and a pre-filter element 21 is disposed within the pre-filter chamber 22. The filtration device 100 further includes a second water inlet pipe 63 and a second water outlet pipe (not labeled). Both the second water inlet pipe 63 and the second water outlet pipe are communicatively connected to the pre-filter chamber 22. The second water inlet pipe 63 is used to convey water into the pre-filter chamber 22, and the second water outlet pipe is used to discharge the water within the pre-filter chamber 22. During actual use, the second water inlet pipe 63 and the second water outlet pipe can be connected to the body of the device that is docked with the filtration device, and this device can be a mineralized water purifier or other mineral water mineralization devices. The water purified by the second filter element assembly 20 is not subjected to mineralization treatment. Users can control the water supply of the mineral water mineralization device to the first filter element assembly and / or the second filter element assembly according to their needs, thereby improving the flexibility of the filtration device 100.

[0056] The pre-filter element 21 can be made by multi-layer folding of polypropylene. Polypropylene is a polymer that can filter out large particulate impurities in water, such as sediment, rust, suspended matter, etc. The pre-filter element 21 can also be doped with activated carbon. The porous structure of the activated carbon gives it a strong adsorption capacity, and it can effectively adsorb harmful substances such as odors, chlorine, and organic matter in water, thereby purifying the water quality.

[0057] Figure 1 and Figure 2 In the illustrated embodiment, the second filter element assembly 20 is disposed at one end of the first filter element assembly 30 and is coaxially arranged with the first filter element assembly 30. At this time, the first filter element assembly 30 and the second filter element assembly 20 are arranged vertically, which can make the second filter element assembly 20 and the first filter element assembly 30 closely arranged in space, enhancing the integrity of the filtration device 100 and reducing the overall volume of the filtration device 100.

[0058] Specifically, the pre-filter element 21 is disposed within the housing 10. The outer peripheral wall of the pre-filter element 21 is spaced from the inner peripheral wall of the housing 10, and a pre-filter water gap 23 is formed therebetween. Moreover, the pre-filter element 21 is hollow inside, and a pre-filter hollow channel 24 is formed therein. That is, the pre-filter element 21 divides the pre-filter chamber 22 into a pre-filter water gap 23 and a pre-filter hollow channel 24. A pre-filter water chamber 50 is provided between the second filter element assembly 20 and the housing 10, and the pre-filter water chamber 50 is communicatively connected to the pre-filter water gap 23. The pre-filter water gap 23 and the pre-filter hollow channel 24 are connected through the pores of the pre-filter element 21. When water flows between the pre-filter water gap 23 and the pre-filter hollow channel 24, that is, when water passes through the pores of the pre-filter element 21, the pre-filter element 21 can adsorb and intercept impurities in the water, thereby purifying the water quality.

[0059] Figure 6The flow path diagram when the second filter element assembly 20 takes in water is shown by a dashed line with arrows. Figure 7 The flow path diagram when the second filter element assembly 20 discharges water is shown by a dashed line with arrows. The filtering device 100 delivers water to the front water passing cavity 50. The water in the front water passing cavity 50 is conveyed to the front hollow channel 24 through the second water inlet pipe 63. The water in the front hollow channel 24 passes through the pores of the front filter element 21 and enters the front water passing gap 23. When the water flows through the pores of the front filter element 21, the front filter element 21 can adsorb and intercept impurities in the water body. Finally, the water in the front water passing gap 23 is discharged outwards through the second water outlet pipe.
