Description

Technical Field

[0001] This utility model relates to the field of mineral spring mineralization equipment technology, and in particular to a filtration device and mineral spring mineralization equipment. Background Technology

[0002] With the improvement of productivity, people's demand for quality of life and convenience is also increasing. Mineralized water is a type of water containing mineral salts and is rich in essential macro- and micro-elements for the human body. Therefore, mineralized water has become popular as drinking water. At the same time, there is also a certain demand for mineralized water containing specific mineral salts during production and experimental processes.

[0003] Currently, mineralized water is typically prepared using mineralization filter cartridges. The mineral salts 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, it's difficult to effectively control the mineral content of mineralized water prepared using this method, especially when the filter cartridge is immersed in water. Because the filter cartridge is in contact with the water for a prolonged period, and because the mineralized filter media is housed within a casing, all the water inside the casing is used to soak the media. This can easily lead to high concentrations of minerals in the water and a high total amount of dissolution, potentially causing the mineral content to exceed safe levels. When the mineral content is excessive, the mineralized water can actually have negative effects on the user. Utility Model Content

[0009] In one embodiment, the first filter element assembly further includes a first filter element cylinder, which is disposed within the outer casing.

[0011] In one embodiment, a second filter element is provided inside the second regulating cavity, and a second filter chamber is provided inside the second filter element. A second water passage gap is formed between the outer peripheral wall of the second filter element and the inner peripheral wall of the first filter element cylinder. The first water outlet pipe is connected to the second water passage gap, and the second one-way conduction structure is disposed between the second filter chamber and the mineralization chamber. Alternatively, the first water outlet pipe is connected to the second filter chamber, and the second one-way conduction structure is disposed between the second water passage gap and the mineralization chamber.

[0012] In one embodiment, the mineralizing filter element has a mineralizing filter cavity inside, and a mineralizing water passage gap is formed between the outer peripheral wall of the mineralizing filter element and the inner peripheral wall of the first filter element cylinder; the first unidirectional conduction structure is disposed between the first regulating cavity and the mineralizing water passage gap, and the second unidirectional conduction structure is disposed between the mineralizing filter cavity and the second regulating cavity; or, the first unidirectional conduction structure is disposed between the first regulating cavity and the mineralizing filter cavity, and the second unidirectional conduction structure is disposed between the mineralizing water passage gap and the second regulating cavity.

In order to avoid unnecessary repetition, the various possible combinations of the various specific technical features / embodiments in this utility model will not be described separately.

[0030] With the improvement of productivity, people's demand for quality of life and convenience is also increasing. Mineralized water is a type of water containing mineral salts and is rich in essential macro- and micro-elements for the human body. Therefore, mineralized water has become popular as drinking water. At the same time, there is also a certain demand for mineralized water containing specific mineral salts during production and experimental processes.

[0031] Currently, mineralized water is typically prepared using mineralization filter cartridges. The mineral salts 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, it's difficult to effectively control the mineral content of mineralized water prepared using this method, especially when the filter cartridge is immersed in water. Because the filter cartridge is in contact with the water for a prolonged period, and because the mineralized filter media is housed within a casing, the media is completely submerged in the water. This can easily lead to a high concentration of minerals in the water and a high total amount dissolving, potentially causing the mineral content to exceed safe levels. When the mineral content is excessive, the mineralized water can actually have negative effects on the user.

[0032] Therefore, this utility model proposes a filtration device to solve the problem that the mineral content in the water is prone to exceed the standard when the mineralized filter element is soaked, and to effectively control the mineral content in the mineralized water.

[0033] Reference Figure 1 and Figure 2The filtration device 100 provided by this utility model includes a housing 1 and a first filter element assembly 2 disposed within the housing 1. The first filter element assembly 2 is provided with a mineralization chamber 21, a first adjustment chamber 22, and a second adjustment chamber 23. A mineralization filter element 24 is disposed within the mineralization chamber 21. The first adjustment chamber 22 is disposed upstream of the mineralization chamber 21, and the second adjustment chamber 23 is disposed downstream of the mineralization chamber 21. A first one-way conduction structure 25 is provided between the first adjustment chamber 22 and the mineralization chamber 21, and a second one-way conduction structure 26 is provided between the second adjustment chamber 23 and the mineralization chamber 21. The first one-way conduction structure 25 is used to open under unidirectional water pressure to conduct the first adjustment chamber 22 and the mineralization chamber 21, and the second one-way conduction structure 26 is used to open under unidirectional water pressure to conduct the mineralization chamber 21 and the second one-way conduction structure 26.

[0034] The first one-way flow structure 25 guides water flow from the first regulating chamber 22 to the mineralization chamber 21, and the second one-way flow structure 26 guides water flow from the mineralization chamber 21 to the second regulating chamber 23. Both the first one-way flow structure 25 and the second one-way flow structure 26 may include a check valve, for example, a duckbill valve. When there is water flow in the opposite direction to the check valve or when there is no water flow, the check valve is closed, and water cannot flow freely between the mineralization chamber 21 and the corresponding regulating chamber. When there is water flow in the forward direction of the check valve, the check valve can open under the pressure of the water flow, allowing water to flow freely between the mineralization chamber 21 and the corresponding regulating chamber.

[0035] When there is no water pressure, both the first unidirectional flow structure 25 and the second unidirectional flow structure 26 remain closed, and the mineralization chamber 21 is relatively isolated from the first regulating chamber 22 and the second regulating chamber 23. When water needs to be supplied to the mineralization chamber 21 for soaking, the filter device 100 supplies water to the first regulating chamber 22. The first unidirectional flow structure 25 opens under the action of water flow to connect the first regulating chamber 22 and the mineralization chamber 21, and the second unidirectional flow structure 26 opens under the action of water flow to connect the mineralization chamber 21 and the second regulating chamber 23. The filter device 100 supplies water to the first regulating chamber 22, the mineralization chamber 21, and the second regulating chamber 23 in sequence. When the water content in the mineralization chamber 21 reaches the required level, the filter device 100 stops supplying water, the water flow disappears, the first unidirectional flow structure 25 and the second unidirectional flow structure 26 close, and the first regulating chamber 22 is relatively isolated from the mineralization chamber 21, and the mineralization chamber 21 is relatively isolated from the second regulating chamber 23. The mineralizing filter element 24 comes into contact with the water in the mineralizing chamber 21 and precipitates minerals. The water in the first regulating chamber 22 and the second regulating chamber 23, which do not have the mineralizing filter element 24, has a low mineral content or even no minerals. When the filtration device 100 finishes the soaking process and outputs water, the first unidirectional flow structure 25 and the second unidirectional flow structure 26 reopen under the action of water flow, and the first regulating chamber 22, the mineralizing chamber 21, and the second regulating chamber 23 are connected. The water with high mineral content in the mineralizing chamber 21 mixes with the water with low mineral content in the first regulating chamber 22 and the second regulating chamber 23, which makes the mineral concentration of the water output by the filtration device 100 moderate. This can effectively control the mineral content in the mineralized water and solve the problem of excessive mineral content in the water when the mineralizing filter element 24 is soaked to a certain extent.

[0036] In summary, this filtration device 100, by setting a first regulating chamber 22 upstream of the mineralization chamber 21 and a second regulating chamber 23 downstream of the mineralization chamber 21, and by setting a first one-way flow structure 25 between the first regulating chamber 22 and the mineralization chamber 21, and a second one-way flow structure 26 between the mineralization chamber 21 and the second regulating chamber 23, allows the operator to flexibly adjust the flow rate and residence time of the water in the mineralization chamber 21, thereby regulating the mineral content in the mineralized water. Furthermore, when the water in the mineralization chamber 21 flows out, the water with high mineral content in the mineralization chamber 21 can mix with the water with low mineral content in the first regulating chamber 22 and the second regulating chamber 23, thus obtaining water with a moderate mineral content, solving the problem of excessive mineral content in traditional methods.

[0037] The mineralization filter element 24 within the mineralization chamber 21 is used for mineralizing water. The material of the mineralization filter element 24 includes mineral materials. For example, the material of the mineralization filter element 24 can be natural rock materials, such as magnesium ore (containing magnesium), celestite (containing strontium), selenium ore (containing selenium), maifanite (containing calcium, magnesium, potassium, sodium, etc.), etc. Alternatively, the material of the mineralization filter element 24 can be a mixture of various rock materials. Alternatively, the material of the mineralization filter element 24 can be an artificially modified material rich in various mineral elements, as long as it can release minerals beneficial to the human body into the water. The material of the mineralization filter element 24 can also include polypropylene and activated carbon, enabling the mineralization filter element 24 to both mineralize and filter the water.

[0038] The first regulating chamber 22, mineralization chamber 21, and second regulating chamber 23 are arranged sequentially along the water flow direction. In practical applications, the first regulating chamber 22, mineralization chamber 21, and second regulating chamber 23 can be arranged axially along the water flow direction, that is, the first regulating chamber 22, mineralization chamber 21, and second regulating chamber 23 are arranged vertically. In this case, the water flow path within the first filter element assembly 2 is from bottom to top or from top to bottom. Alternatively, the first regulating chamber 22, mineralization chamber 21, and second regulating chamber 23 can be arranged sequentially from the inside to the outside along the water flow direction, that is, the mineralization chamber 21 surrounds the first regulating chamber 22, and the second regulating chamber 23 surrounds the mineralization chamber 21, with the first regulating chamber 22, mineralization chamber 21, and second regulating chamber 23 having an inner-outer outer relationship. In this case, the water flow path within the first filter element assembly 2 is from the inside to the outside or from the outside to the inside. Alternatively, the first regulating chamber 22 and the second regulating chamber 23 can be arranged internally and externally, with the mineralization chamber 21 located at one end of the first regulating chamber 22 and the second regulating chamber 23. That is, the first regulating chamber 22 and the second regulating chamber 23 are arranged in an inner-outer-outer relationship; either the first regulating chamber 22 can be fitted over the second regulating chamber 23, or the second regulating chamber 23 can be fitted over the first regulating chamber 22. Then, the mineralization chamber 21 is arranged vertically above and below the first regulating chamber 22 and the second regulating chamber 23. In this case, the water flow path within the first filter element assembly 2 is from the first regulating chamber 22 vertically to the mineralization chamber 21, and then the water in the mineralization chamber 21 returns to the second regulating chamber 23.

[0039] In this technical solution, the first unidirectional conduction structure 25 and the second unidirectional conduction structure 26 may also include a magnetic attraction component. The magnetic attraction component includes a first magnetic element and a second magnetic element. The polarities of the first magnetic element and the second magnetic element are opposite on the opposite sides. The first magnetic element is used to separate from the second magnetic element under unidirectional water pressure to open the corresponding unidirectional conduction structure.

[0040] Optionally, the first unidirectional flow structure 25 and the second unidirectional flow structure 26 may further include an elastic valve. The elastic valve has an elastic channel that can automatically close under the action of an elastic restoring force. The elastic valve is used to deform under the action of unidirectional water pressure to open the elastic channel. Specifically, the elastic valve may have a guide surface on the side facing the water flow direction, and the elastic channel is located at the end of the guide surface. Under the guidance of the guide surface, the water flow impacts the elastic valve, compressing the elastic valve around the elastic channel, thereby opening the elastic channel and connecting the mineralization chamber 21 and the corresponding regulating chamber through the elastic channel.

[0041] The filtration device 100 also includes a first inlet pipe 5 and a first outlet pipe 6. The first inlet pipe 5 is connected to the first regulating chamber 22, and the first outlet pipe 6 is connected to the second regulating chamber 23. The first inlet pipe 5 is used to supply water to the first regulating chamber 22, and the first outlet pipe 6 is used to discharge water from the second regulating chamber 23. In actual use, the first inlet pipe 5 and the first outlet pipe 6 can be connected to the body of a device that interfaces with the filtration device 100, such as a mineral water purifier or other mineralizing equipment.

[0042] In some embodiments of the filtration device 100, the first filter element assembly 2 may include a first filter element 27, which is disposed within the first adjustment chamber 22.

[0043] The first filter element 27 can be made of nanomaterials, such as nanofibers, nanoceramics, and nano-activated carbon. These materials have nanoscale pores, high specific surface area, and high adsorption capacity, effectively removing nanoscale particles such as bacteria, viruses, and organic matter, thus enabling secondary filtration of the water. Alternatively, antibacterial materials such as nano-silver can be added to the first filter element 27 to inhibit bacterial growth. Or, charged fibers can be added to the first filter element 27. These charged fibers possess charge properties and a nanoscale porous structure, enabling them to remove tiny particles, bacteria, viruses, and organic matter from the water through electrostatic adsorption. Industrially, the fiber surface can be modified using chemical methods to introduce charged groups, thereby endowing the fibers with charge properties.

[0044] The first regulating chamber 22 is equipped with a first filter element 27, which enables the first regulating chamber 22 to not only regulate the mineralization concentration of the water, but also to increase the filtration level of the filtration device 100. Before entering the mineralization chamber 21, the water is purified by the first filter element 27 and then undergoes mineralization treatment. This allows the first regulating chamber 22 to purify the water while regulating its mineralization concentration, thereby improving the quality of the water.

[0045] The first filter element 27 has a first filter cavity 221 inside, and a first water passage gap 222 is formed between the outer peripheral wall of the first filter element 27 and the inner peripheral wall of the first filter element cylinder 29. A first unidirectional conduction structure 25 can be disposed in the coverage area of ​​the first filter cavity 221, and a first water inlet pipe 5 can be connected to the first water passage gap 222.

[0046] Specific reference Figure 1 and Figure 2 The first filter element assembly 2 includes a first filter element cylinder 29, which is disposed within the outer casing 1. A first partition 30 and a second partition 31 are spaced apart within the first filter element cylinder 29, dividing the chamber of the first filter element cylinder 29 into a first adjustment chamber 22, a mineralization chamber 21, and a second adjustment chamber 23. The first adjustment chamber 22 and the second adjustment chamber 23 are respectively located at opposite ends of the mineralization chamber 21. A first unidirectional conduction structure 25 is disposed on the first partition 30, and a second unidirectional conduction structure 26 is disposed on the second partition 31.

[0047] The first filter element 27 is disposed within the first regulating cavity 22. A first filter chamber 221 is formed inside the first filter element 27. The outer peripheral wall of the first filter element 27 is spaced apart from the inner peripheral wall of the first filter element cylinder 29, forming a first water passage gap 222 between them. In other words, the first filter element 27 divides the first regulating cavity 22 into the inner and outer first filter chamber 221 and the first water passage gap 222. The first water inlet pipe 5 can be connected to the first water passage gap 222 for supplying water to the first water passage gap 222. At this time, the first unidirectional conduction structure 25 is disposed between the first filter chamber 221 and the mineralization cavity 21. The first water passage gap 222 and the first filter chamber 221 are connected through the pores of the first filter element 27. When water flows between the first water passage gap 222 and the first filter chamber 221, that is, when water flows through the pores of the first filter element 27, the first filter element 27 can adsorb and intercept impurities in the water, thereby purifying the water quality.

[0048] At this time, the flow path of the water between the first regulating chamber 22 and the mineralization chamber 21 is as follows: the filter device 100 sends water to the first water passage gap 222 through the first water inlet pipe 5. The water in the first water passage gap 222 passes through the pores of the first filter element 27 and enters the first filter chamber 221. During this process, the first filter element 27 adsorbs and intercepts impurities in the water. The first one-way conduction structure 25 is opened under the action of water flow to connect the first filter chamber 221 and the mineralization chamber 21. The water filtered by the first filter element 27 flows into the mineralization chamber 21 through the first one-way conduction structure 25 for soaking.

[0049] Alternatively, the first water inlet pipe 5 can be connected to the first filter chamber 221, and the first one-way flow structure 25 can be disposed between the first water passage gap 222 and the mineralization chamber 21. In this case, the first water inlet pipe 5 is used to deliver water to the first filter chamber 221. The first water inlet pipe 5 first delivers water to the first filter chamber 221, and then the water in the first filter chamber 221 passes through the pores of the first filter element 27 and enters the first water passage gap 222. The first one-way flow structure 25 opens under the action of water flow to connect the first water passage gap 222 and the mineralization chamber 21. The water filtered by the first filter element 27 flows into the mineralization chamber 21 through the first one-way flow structure 25 for soaking.

[0050] The filtration device 100 has a first filter chamber 221 inside the first filter element 27 and a first water passage gap 222 outside the first filter element 27. The first unidirectional conduction structure 25 is set on the other side of the water inlet side, which can ensure that only the water purified by the first filter element 27 can enter the mineralization chamber 21, thereby ensuring the quality of the water.

[0051] In some embodiments of the filtration device 100, the first filter element assembly 2 may include a second filter element 28, which is disposed within the second adjustment chamber 23.

[0052] Similarly, the second filter element 28 can be made of nanomaterials, such as nanofibers, nanoceramics, and nano-activated carbon. These materials have nanoscale pores, high specific surface area, and high adsorption capacity, effectively removing nanoscale particles such as bacteria, viruses, and organic matter, thus enabling secondary filtration of the water. Alternatively, antibacterial materials such as nano-silver can be added to the second filter element 28 to inhibit bacterial growth. Alternatively, charged fibers can be added to the second filter element 28. Charged fibers possess charge properties and a nanoscale porous structure, enabling them to remove tiny particles, bacteria, viruses, and organic matter from the water through electrostatic adsorption. Industrially, the fiber surface can be modified using chemical methods to introduce charged groups, thereby endowing the fibers with charge properties. The material of the second filter element 28 can be the same as or different from that of the first filter element 27; no restrictions are placed here.

[0053] The second regulating chamber 23 is equipped with a second filter element 28, which enables the second regulating chamber 23 to not only regulate the mineralization concentration of the water, but also to increase the filtration level of the filtration device 100. After the water flows out of the mineralization chamber 21, it is purified by the second filter element 28, so that the second regulating chamber 23 can purify the water while regulating the mineralization concentration, thereby improving the quality of the water.

[0054] The second filter element 28 has a second filter cavity 231 inside, and a second water passage gap 232 is formed between the outer peripheral wall of the second filter element 28 and the inner peripheral wall of the first filter element cylinder 29. That is, the outer peripheral wall of the second filter element 28 and the inner peripheral wall of the first filter element cylinder 29 are spaced apart, forming a second water passage gap 232 between them. In other words, the second filter element 28 divides the second regulating cavity 23 into the inner and outer second filter cavity 231 and the second water passage gap 232. The second water passage gap 232 and the second filter cavity 231 are connected through the pores of the second filter element 28. When water flows between the second water passage gap 232 and the second filter cavity 231, that is, when water flows through the pores of the second filter element 28, the second filter element 28 can adsorb and intercept impurities in the water, thereby purifying the water quality.

[0055] The first outlet pipe 6 can be connected to the second water passage gap 232 for outputting water from the second water passage gap 232. At this time, the second unidirectional flow structure 26 is positioned between the second filter chamber 231 and the mineralization chamber 21. When the filtration device 100 finishes the soaking process and outputs water, the flow path of the water between the mineralization chamber 21 and the second regulating chamber 23 is as follows: the second unidirectional flow structure 26 opens under the action of water flow to connect the mineralization chamber 21 and the second filter chamber 231. Water in the mineralization chamber 21 flows into the second filter chamber 231 through the second unidirectional flow structure 26. Water in the second filter chamber 231 passes through the pores of the second filter element 28 and enters the second water passage gap 232. During this process, the second filter element 28 adsorbs and intercepts impurities in the water. Finally, the water in the second water passage gap 232 is discharged outwards through the first outlet pipe 6.

[0056] Alternatively, the first outlet pipe 6 can be connected to the second filter chamber 231, and the second one-way flow structure 26 can be disposed between the second water passage gap 232 and the mineralization chamber 21. In this case, the first outlet pipe 6 is used to output the water in the second filter chamber 231. At this time, when the filtration device 100 finishes the soaking process and outputs water, the flow path of the water between the mineralization chamber 21 and the second regulating chamber 23 is as follows: the second one-way flow structure 26 opens under the action of water flow to connect the mineralization chamber 21 and the second water passage gap 232, the water in the mineralization chamber 21 flows into the second water passage gap 232 through the second one-way flow structure 26, the water in the second water passage gap 232 passes through the pores of the second filter element 28 and enters the second filter chamber 231, and finally, the water in the second filter chamber 231 is discharged outward through the first outlet pipe 6.

[0057] In this embodiment, a second filter chamber 231 is provided inside the second filter element 28, and a second water passage gap 232 is provided outside the second filter element 28. The second unidirectional conduction structure 26 is set on the other side of the water inlet side, which can ensure that the water flowing out of the mineralization chamber 21 is purified by the second filter element 28 before being discharged, thereby ensuring the quality of the water.

[0058] In practical applications, the first filter assembly 2 can be equipped with only the first filter element 27 or the second filter element 28, or both. When the first filter assembly 2 is equipped with both the first filter element 27 and the second filter element 28, the first filter element 27 performs preliminary purification of the water in the first regulating chamber 22, and the second filter element 28 performs further purification of the mineralized water in the second regulating chamber 23. Through the dual purification of the first filter element 27 and the second filter element 28, the water undergoes deep purification before entering the mineralization chamber 21 and after leaving the mineralization chamber 21. This multi-stage purification method can significantly improve the quality of the water, ensuring that the final output mineralized water not only has a moderate mineral content but is also purer and meets higher drinking water standards.

[0059] exist Figures 1 to 3 In the illustrated embodiment, a first filter cartridge body 29 is disposed within the outer casing 1. A first partition 30 and a second partition 31 are spaced apart within the first filter cartridge body 29, dividing the chamber of the first filter cartridge body 29 into a first regulating chamber 22, a mineralization chamber 21, and a second regulating chamber 23.

The first water inlet pipe 5 is connected to the first water passage cavity 33, and a first unidirectional conduction structure 25 is disposed between the first filter cavity 221 and the mineralization cavity 21.

[0061] The second regulating chamber 23 contains a second filter element 28, and the second filter element 28 contains a second filter cavity 231. A second water passage gap 232 is formed between the outer peripheral wall of the second filter element 28 and the inner peripheral wall of the first filter element cylinder 29. The first filter element assembly 2 may also include a second end cap 34. The first filter element cylinder 29 has a first end wall and a second end wall arranged vertically opposite to each other. The second end cap 34 is disposed in the second regulating chamber 23 and spaced apart from the second partition 31. The second filter element 28 is sandwiched between the second end cap 34 and the second end wall. A second water passage cavity 35 is formed between the second end cap 34 and the second partition 31.

A second unidirectional conduction structure 26 is disposed between the second water passage cavity 35 and the mineralization cavity 21. The first water outlet pipe 6 is connected to the second filter cavity 231.

[0062] The mineralizing filter element 24 has a mineralizing filter chamber 211 inside, and a mineralizing water passage gap 212 is formed between the outer peripheral wall of the mineralizing filter element 24 and the inner peripheral wall of the first filter element cylinder 29. The first filter element assembly 2 also includes a third end cap 36, and a second end cap 34 is disposed in the mineralizing chamber 21 and spaced apart from the first partition 30. The mineralizing filter element 24 is sandwiched between the third end cap 36 and the second partition 31. A third water passage chamber 37 is formed between the third end cap 36 and the first partition 30. The third water passage chamber 37 is connected to the first regulating chamber 22.

[0063] Figure 3The flow path diagram of the first filter element assembly 2 is shown with a dashed line with an arrow. The water flow path of the first filter element assembly 2 is as follows: the filter device 100 sends water to the first water passage chamber 33 through the first water inlet pipe 5. The water in the first water passage chamber 33 flows into the first water passage gap 222. The water in the first water passage gap 222 passes through the pores of the first filter element 27 and flows into the first filter cavity 221. When the water flows through the pores of the first filter element 27, the first filter cavity 221 can adsorb and intercept impurities in the water. The first unidirectional flow structure 25 opens under water pressure to connect the first filter chamber 221 and the third water passage chamber 37. Water in the first filter chamber 221 flows into the third water passage chamber 37 through the first unidirectional flow structure 25. Water in the third water passage chamber 37 flows into the mineralization water passage gap 212. Water in the mineralization water passage gap 212 passes through the pores of the mineralization filter element 24 and enters the mineralization filter chamber 211. As the water flows through the pores of the mineralization filter element 24, the mineralization filter element 24 can adsorb and intercept impurities in the water, and minerals on the mineralization filter element 24 will precipitate out. During this process, the water with high mineral content in the mineralization chamber 21 mixes with the water with low mineral content in the first regulating chamber 22, thereby obtaining water with a moderate mineral concentration. The second unidirectional flow structure 26 opens under water pressure to connect the mineralization filter chamber 211 and the second water passage chamber 35. Water in the mineralization filter chamber 211 flows into the second water passage chamber 35, and water in the second water passage chamber 35 flows into the second water passage gap 232. Water in the second water passage gap 232 passes through the pores of the second filter element 28 and flows into the second filter chamber 231. As the water flows through the pores of the second filter element 28, the second filter chamber 231 can adsorb and intercept impurities in the water. Finally, the water in the second filter chamber 231 is discharged outward through the first outlet pipe 6.

[0064] The first inlet pipe 5 can be fitted onto the first outlet pipe 6. The diameter of the first inlet pipe 5 is larger than that of the first outlet pipe 6. A water conveying channel is formed between the pipe walls of the first inlet pipe 5 and the first outlet pipe 6. The filtration device 100 delivers water to the first water passage chamber 33 through this water conveying channel. This design integrates the first inlet pipe 5 and the first outlet pipe 6 together, reducing the complexity of the pipe layout and thus reducing the space occupied by the first inlet pipe 5 and the first outlet pipe 6, making the overall size of the filtration device 100 smaller.

[0065] Reference Figure 1 , Figure 4 and Figure 5In some embodiments of the filtration device 100, a second filter element assembly 4 may be included. The second filter element assembly 4 is disposed within the housing 1, and a pre-filter chamber 41 is provided between the second filter element assembly 4 and the housing 1. A pre-filter element 42 is disposed within the pre-filter chamber 41. The filtration device 100 also includes a second inlet pipe 7 and a second outlet pipe (not shown), both of which are connected to the pre-filter chamber 41. The second inlet pipe 7 is used to supply water to the pre-filter chamber 41, and the second outlet pipe is used to discharge the water from the pre-filter chamber 41. In actual use, the second inlet pipe 7 and the second outlet pipe can be connected to the body of a device that docks with the filtration device 100, such as a mineral water purifier or other mineralization equipment. Users can control the mineral water mineralization equipment to deliver water to the first filter element 2 and / or the second filter element 4 according to their needs. That is, users can choose whether to perform mineralization treatment on the water according to their own needs. If users only need pure water, they can use the second filter element 4 for purification treatment without going through the mineralization treatment of the first filter element 2.

[0066] The pre-filter cartridge 42 can be made of multi-layered folded polypropylene. Polypropylene is a high-molecular polymer that can filter out large particulate impurities in the water, such as silt, rust, and suspended solids. The pre-filter cartridge 42 can also be doped with activated carbon. The porous structure of activated carbon gives it a strong adsorption capacity, effectively adsorbing harmful substances such as odors, chlorine, and organic matter in the water, thereby purifying the water. The second filter cartridge assembly 4 can filter and purify the water.

[0067] The pre-filter element 42 has a third filter chamber 411 inside. A pre-water passage gap 412 is formed between the outer peripheral wall of the pre-filter element 42 and the inner peripheral wall of the outer shell 1. That is, the pre-filter element 42 divides the pre-filter chamber 41 into the third filter chamber 411 and the pre-water passage gap 412, which are arranged inside and outside. The third filter chamber 411 and the pre-water passage gap 412 are connected through the pores of the pre-filter element 42. When the water flows between the third filter chamber 411 and the pre-water passage gap 412, that is, when the water flows through the pores of the pre-filter element 42, the pre-filter element 42 can adsorb and intercept impurities in the water, thereby purifying the water quality.

[0068] The second inlet pipe 7 can be connected to the pre-filter gap 412, and the second outlet pipe can be connected to the third filter chamber 411. In this case, the second inlet pipe 7 supplies water to the pre-filter gap 412, and the second outlet pipe discharges water from the third filter chamber 411. The water flow path between the second filter element assemblies 4 is as follows: the filter device 100 supplies water to the pre-filter gap 412 through the second inlet pipe 7; the water in the pre-filter gap 412 passes through the pores of the pre-filter element 42 and enters the third filter chamber 411. During this process, the pre-filter element 42 adsorbs and intercepts impurities in the water. Subsequently, the water in the third filter chamber 411 is discharged through the second outlet pipe. Therefore, the water flow path of the second filter element assembly 4 is external inlet and internal outlet.

[0069] Alternatively, the second inlet pipe 7 can be connected to the third filter chamber 411, and the second outlet pipe can be connected to the pre-filter gap 412. In this case, the water flow path between the second filter element assemblies 4 is as follows: the filter device 100 supplies water to the third filter chamber 411 through the second inlet pipe 7; the water in the third filter chamber 411 passes through the pores of the pre-filter element 42 and enters the pre-filter gap 412. During this process, the pre-filter element 42 adsorbs and intercepts impurities in the water; subsequently, the water in the pre-filter gap 412 is discharged through the second outlet pipe. In this case, the water flow path of the second filter element assembly 4 is inward inlet and outward outlet. Figure 4 and Figure 5 As shown.

[0070] Figure 1 In the illustrated embodiment, the second filter element assembly 4 is disposed at one end of the first filter element assembly 2 and is axially arranged with the first filter element assembly 2. Disposing the second filter element assembly 4 at one end of the first filter element assembly 2 and axially arranged with the first filter element assembly 2 allows the second filter element assembly 4 and the first filter element assembly 2 to be spatially compact, enhancing the overall integrity of the filtration device 100 and reducing the overall volume of the filtration device 100.

[0071] The second filter element assembly 4 may be provided with a front water passage chamber 43 between the second filter element assembly 4 and the outer shell 1, and the front water passage chamber 43 is connected to the front water passage gap 412.

[0072] Figure 4 and Figure 5 The flow chart showing the inlet and outlet of the second filter element assembly 4 is shown. Figure 4 The flow path diagram of the second filter element assembly 4 during water inlet is shown with a dashed line bearing an arrow. Figure 5The flow path diagram of the second filter element assembly 4 when water is discharged is shown with a dashed line with an arrow. The filtration device 100 sends water to the third filter chamber 411 through the second inlet pipe 7. The water in the third filter chamber 411 passes through the pores of the pre-filter element 42 and enters the pre-passing water gap 412. During this process, the pre-filter element 42 adsorbs and intercepts impurities in the water. Subsequently, the water in the pre-passing water gap 412 flows into the pre-passing water chamber 43 and is finally discharged through the second outlet pipe.

[0073] Figure 6 and Figure 7 The flow chart of the second filter element assembly 4 (outer inlet, inner outlet) is shown. Figure 6 The flow path diagram of the second filter element assembly 4 during water inlet is shown with a dashed line bearing an arrow. Figure 7 The flow path diagram of the second filter element assembly 4 when water is discharged is shown with a dashed line with an arrow. Specifically, the filtration device 100 can first send water to the pre-filter chamber 43. The water in the pre-filter chamber 43 flows into the pre-filter gap 412. The water in the pre-filter gap 412 passes through the pores of the pre-filter element 42 and enters the third filter chamber 411. During this process, the pre-filter element 42 adsorbs and intercepts impurities in the water. Subsequently, the water in the third filter chamber 411 is discharged through the second outlet pipe.

[0074] The second inlet pipe 7 can be fitted onto the first inlet pipe 5, and the first inlet pipe 5 can be fitted onto the first outlet pipe 6. The diameter of the second inlet pipe 7 is larger than that of the first inlet pipe 5, and the diameter of the first inlet pipe 5 is larger than that of the first outlet pipe 6. A first water conveying channel is formed between the wall of the second inlet pipe 7 and the wall of the first inlet pipe 5, and a second water conveying channel is formed between the wall of the first inlet pipe 5 and the wall of the first outlet pipe 6. The filter device 100 delivers water to the forward water passage chamber 43 through the first water conveying channel and to the first water passage chamber 33 through the second water conveying channel. This design integrates the second inlet pipe 7, the first inlet pipe 5, and the first outlet pipe 6, reducing the complexity of the pipe layout and thus reducing the space occupied by the pipes, making the overall size of the filter device 100 smaller.
