[0031] With the improvement of productivity, people's demand for the quality of life and convenience is increasing. Minerolized water is a kind of water containing mineral salts, rich in essential macroelements and trace elements for the human body, so minerolized water as drinking water is favored by people. At the same time, there is also a certain demand for minerolized water containing specific mineral salts in production and experiments.

[0032] At present, there are two common ways to prepare minerolized water. The first is to manually configure mineral salts with water into minerolized water with appropriate concentration, but this method is very troublesome, has a certain chemical knowledge threshold and is low in efficiency. The second is to put mineral stones containing mineral salts into a container containing water, such as a drinking water dispenser or a water purifier, so that the mineral salts in the mineral stones can dissolve into the water in the container, and the water can be changed into minerolized water. However, it is difficult to effectively control the mineral content in the minerolized water prepared by this method, and many mineral salts are poor in solubility and difficult to dissolve from the mineral stones, so the water in the container cannot contain sufficient mineral salts after directly soaking the mineral stones. When the mineral content is insufficient, the minerolized water cannot meet the user's demand.

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

[0034] Referring to Figures 1-7 , Figure 1 The assembly structure of the filter element assembly provided by the present application is shown. Figure 2 The cross-sectional structure diagram of an embodiment of the filter element assembly provided by the present application without promoting filter material and mineralization filter material is shown. Figure 3 The cross-sectional structure diagram of an embodiment of the filter element assembly provided by the present application is shown. Figure 4 The exploded cross-sectional structure diagram of an embodiment of the filter element assembly provided by the present application is shown. Figure 5 The cross-sectional structure diagram of another embodiment of the filter element assembly provided by the present application without promoting filter material and mineralization filter material is shown. Figure 6 The cross-sectional structure diagram of another embodiment of the filter element assembly provided by the present application is shown. Figure 7An exploded view of another embodiment of the filter cartridge assembly is provided. A filter cartridge assembly 1 is provided in an embodiment of the present application, which includes a promoting filter material 81 and a mineralizing filter material 91.

[0035] The filter cartridge assembly 1 is provided with an inner water path 2, and the promoting filter material 81 and the mineralizing filter material 91 are connected in series between a water inlet 22 and a water outlet 23 of the inner water path 2. The mineralizing filter material 91 contains soluble minerals, and the promoting filter material 81 contains promoting substances that can promote the dissolution of the minerals in the mineralizing filter material 91.

[0036] In the structure provided in the embodiment, the promoting filter material 81 and the mineralizing filter material 91 are connected in series in the inner water path 2 of the filter cartridge assembly 1. In the flow state of the filter cartridge assembly 1, the promoting substances in the promoting filter material 81 are normally dissolved into the flowing water, and since the mineralizing filter material 91 is arranged downstream of the promoting filter material 81, the promoting substances flow to the mineralizing filter material 91 along with the water, thereby promoting the dissolution of the minerals in the mineralizing filter material 91 into the flowing water, so as to increase the mineral content of the mineralized water output by the filter cartridge assembly 1 in the flow state.

[0037] In the soaking state of the filter cartridge assembly 1, the soaking water in the inner water path 2 no longer flows through the promoting filter material 81 and then through the mineralizing filter material 91. Although the soaking water no longer has a macroscopic flow trend, the mineralizing filter material 91 and the promoting filter material 81 are actually in communication, so that the promoting substances can also diffuse in the soaking water to move to the mineralizing filter material 91, thereby promoting the dissolution of the minerals into the soaking water, so as to increase the mineral content of the mineralized water output by the filter cartridge assembly 1 in the soaking state. Through the structure of the filter cartridge assembly 1 provided in the present application, the mineral content of the mineralized water can be effectively increased in both the flow state and the soaking state, and the probability of insufficient mineral content in the mineralized water is reduced, thereby improving the stability and usability of the filter cartridge assembly 1.

[0038] Optionally, the promoting filter material 81 can include weakly acidic filter material, such as weakly acidic ore. The mineralizing filter material 91 can include calcium mineralizing filter material 91 and magnesium mineralizing filter material 91, such as calcium-rich and magnesium-rich ore. The promoting filter material 81 can dissolve acidic substances in the water, which can promote the dissolution of calcium, magnesium, and other mineral elements in the mineralizing filter material 91, thereby achieving the effect of increasing the mineral content of the mineralized water.

[0039] In an embodiment of the present application, the filter cartridge assembly 1 includes a filter cartridge 3, which is provided with a first accommodating cavity 8 and a second accommodating cavity 9 in sequence along the direction of the inner water path 2. The promoting filter material 81 is accommodated in the first accommodating cavity 8, and the mineralizing filter material 91 is accommodated in the second accommodating cavity 9. The first accommodating cavity 8 and the second accommodating cavity 9 are arranged in the filter cartridge 3 in the axial direction of the filter cartridge 3.

[0040] In the structure provided in the specific embodiment, and the first accommodating cavity 8 and the second accommodating cavity 9 are arranged along the axial direction of the filter cartridge 3, so that the water body can sequentially contact the promoting filter material 81 and the mineralizing filter material 91 when flowing along the filter cartridge 3, and the dissolution of the mineral substances in the mineralizing filter material can be effectively promoted by the promoting substances in both the flowing state and the soaking state, so that the content of the mineral substances in the mineralized water output by the filter element assembly 1 is ensured, the probability of the low content of the mineral substances in the mineralized water is reduced, and the stability and usability of the filter element assembly 1 are improved.

[0041] In one specific embodiment of the present application, the first accommodating cavity 8 can be arranged above the second accommodating cavity 9.

[0042] In the structure provided in the specific embodiment, the first accommodating cavity 8 is arranged above the second accommodating cavity 9, so that the water body can enter the second accommodating cavity 9 through the promoting filter material 81 in the first accommodating cavity 8 under the action of gravity in the flowing state, and the filtering process can be promoted under the action of gravity while the backflow probability is low. In the soaking state, the water bodies in the first accommodating cavity 8 and the second accommodating cavity 9 can also flow to each other, so that the dissolution of the mineral substances in the mineralizing filter material can be effectively promoted by the promoting substances in both the flowing state and the soaking state, the probability of the low content of the mineral substances in the mineralized water is reduced, and the stability and usability of the filter element assembly 1 are improved.

[0043] In one specific embodiment of the present application, the filter element assembly 1 can include a first separation piece 4 provided with at least one first through hole 41. The first separation piece 4 is arranged between the first accommodating cavity 8 and the second accommodating cavity 9, and the fluid in the first accommodating cavity 8 can enter the second accommodating cavity 9 through the at least one first through hole 41.

[0044] In the structure provided in the specific embodiment, the first accommodating cavity 8 and the second accommodating cavity 9 are separated by the first separation piece 4, so that the water body in the first accommodating cavity 8 can only enter the second accommodating cavity 9 through the first through hole 41, and the water flow between the first accommodating cavity 8 and the second accommodating cavity 9 is limited by the first through hole 41, for example, the flow rate, flow volume and flow direction are controlled, so that the water body can flow uniformly between the first accommodating cavity 8 and the second accommodating cavity 9, and the stability and usability of the filter element assembly 1 are improved.

[0045] Optionally, the number of the first through holes 41 can be multiple, and the multiple first through holes 41 are uniformly arranged on the first separation piece 4, so that the fluid between the first accommodating cavity 8 and the second accommodating cavity 9 can uniformly flow through the multiple first through holes 41. The problem that the water flow between the first accommodating cavity 8 and the second accommodating cavity 9 is too concentrated, resulting in too fast flow rate and serious erosion in local position, thereby affecting the service life of the mineralizing filter material 91 and the promoting filter material 81, can be avoided.

[0046] Referring to Figures 1-4In an embodiment of the present application, the filter cartridge 3 can include an outer cylinder 31 and a first inner cylinder 32, and the outer cylinder 31 is sleeved on the outer periphery of the first inner cylinder 32. The first accommodating cavity 8 and the second accommodating cavity 9 are arranged in the first inner cylinder 32 from top to bottom, and the upper end of the first inner cylinder 32 is provided with the first inlet 321 and the lower end is provided with the first outlet 322. The water inlet 22 and the water outlet 23 are arranged at the lower end of the outer cylinder 31, the first outlet 322 is connected with the water outlet 23, and the first inlet 321 is connected with the water inlet 22.

[0047] In the structure provided in the embodiment, the first inner cylinder 32 is used to limit the positions of the mineralization filter material 91 and the promotion filter material 81, so that the water flow direction in the overflow state can be controlled to flow from the first accommodating cavity 8 to the second accommodating cavity 9. The first inlet 321 is arranged at the upper end of the first inner cylinder 32, so that the water level between the outer cylinder 31 and the first inner cylinder 32 of the filter core assembly 1 must be raised to immerse the upper end of the first inner cylinder 32 before the water can enter the first accommodating cavity 8 through the first inlet 321. The water level in the filter core assembly 1 can be maintained, so that the promotion filter material 81 can be fully contacted with the water body.

[0048] In addition, the first outlet 322 is arranged at the lower end of the first inner cylinder 32, and the water body entering the first accommodating cavity 8 through the first inlet 321 is filtered by the promotion filter material 81 and the mineralization filter material 91 under the action of the water pressure in the overflow state, and is also subjected to the action of gravity. The gravity can further improve the filtering efficiency of the promotion filter material 81 and the mineralization filter material 91 for the water body, so that the promotion filter material 81 and the mineralization filter material 91 can be more fully contacted with the water body, and the working efficiency of the filter core assembly 1 can be improved by using the natural gravity.

[0049] In an embodiment of the present application, the filter core assembly 1 further includes a second separation piece 5. The second separation piece 5 is provided with at least one second through hole 51. The inner water channel 2 includes a first water inlet channel 21 arranged between the outer cylinder 31 and the first inner cylinder 32. The second separation piece 5 covers the first inlet 321, and the fluid in the first water inlet channel 21 can enter the first accommodating cavity 8 through the at least one second through hole 51.

[0050] In the structure provided in the embodiment, the second separation piece 5 can be used to control the water flow entering the first accommodating cavity 8 from the first water inlet channel 21 through the first inlet 321, and the second through hole 51 can be used to limit the water flow between the first accommodating cavity 8 and the first water inlet channel 21, for example, to control the flow rate, flow volume and flow direction, so that the water body between the first accommodating cavity 8 and the first water inlet channel 21 can flow uniformly, thereby improving the stability and usability of the filter core assembly 1.

[0051] Optionally, the second partition 5 can also be arranged between the second accommodating cavity 9 and the first outlet 322, and the fluid in the second accommodating cavity 9 can enter the first outlet 322 through the at least one second through hole 51.

[0052] In the structure provided in the specific embodiment, as with the first partition 4, the second partition 5 is used to separate the second accommodating cavity 9 from the first outlet 322, so that the water in the second accommodating cavity 9 can only enter the first outlet 322 through the second through hole 51, thereby limiting the water flow between the second accommodating cavity 9 and the first outlet 322, such as controlling the flow rate, flow volume and flow direction, so that the water between the second accommodating cavity 9 and the first outlet 322 can flow uniformly, thereby improving the stability and usability of the filter element assembly 1.

[0053] Optionally, the number of second through holes 51 can be multiple, and multiple second through holes 51 are uniformly arranged on the second partition 5, so that the fluid between the first accommodating cavity 8 and the first water inlet channel 21, and / or between the second accommodating cavity 9 and the first outlet 322 can flow uniformly through the multiple second through holes 51. It can avoid the water flow between the first accommodating cavity 8 and the first water inlet channel 21, and / or between the second accommodating cavity 9 and the first outlet 322 being too concentrated, resulting in too fast flow rate and serious erosion at local positions, thereby affecting the service life of the mineralization filter material 91 and / or promoting the service life of the filter material 81.

[0054] Referring to Figure 5 , Figure 6 , Figure 7 In the specific embodiment of the present application, the filter cartridge 3 can include an outer cylinder 31 and a second inner cylinder 33, and the outer cylinder 31 is sleeved on the outer periphery of the second inner cylinder 33. The second accommodating cavity 9 is arranged in the second inner cylinder 33, and the filter material 81 and the second inner cylinder 33 are arranged from top to bottom along the axial direction of the filter cartridge 3. The upper end of the second inner cylinder 33 is provided with a second inlet 331, and the lower end is provided with a second outlet 332. The water inlet 22 and the water outlet 23 are arranged at the lower end of the outer cylinder 31, the first partition 4 is arranged on the second inlet 331, and the second outlet 332 is connected to the water outlet 23.

[0055] In the structure provided in the specific embodiment, the second inner cylinder 33 can be used in cooperation with the first partition 4 to form the second accommodating cavity 9, thereby limiting the flow direction of the water flow under the overflow state, and the second inlet 331 is arranged at the upper end of the first inner cylinder 32, so that the water level between the outer cylinder 31 and the second inner cylinder 33 of the filter element assembly 1 must be raised to immerse the upper end of the second inner cylinder 33, and the water can enter the second accommodating cavity 9 through the second inlet 331, so that the water level in the filter element assembly 1 can be maintained, so that the promoting filter material 81 can be fully contacted with the water, and a sufficient amount of promoting substances can be dissolved into the water to promote the dissolution of minerals.

[0056] In an embodiment of the present application, the filter element assembly 1 can further comprise a first end cover 61, and the filter aid 81 can be provided with a first central passage 82. The first end cover 61 and the first partition 4 are respectively arranged at the two ends of the filter aid 81. One end of the first central passage 82 is blocked by the first end cover 61, and the other end of the first central passage 82 is connected to the first through hole 41.

[0057] In an embodiment of the present application, the filter element assembly 1 can further comprise a first end cover 61, and the filter aid 81 can be provided with a first central passage 82. The first end cover 61 and the first partition 4 are respectively arranged at the two ends of the filter aid 81. One end of the first central passage 82 is blocked by the first end cover 61, and the other end of the first central passage 82 is connected to the first through hole 41.

[0058] In the structure provided in the embodiment, the first central passage 82 can be used to guide the water filtered by the mineralization filter aid 91, so that the water flows into the second containing cavity 9 through the first through hole 41. The first end cover 61 can ensure that the water entering the first central passage 82 is filtered by the filter aid 81, so that the water containing the promoting substances enters the second containing cavity 9 to promote the dissolution of minerals, which can improve the stability and usability of the filter element assembly 1.

[0059] In an embodiment of the present application, the filter element assembly 1 can further comprise a second end cover 62, and the mineralization filter aid 91 can be provided with a second central passage 92. One end of the mineralization filter aid 91 is connected to the second inner cylinder 33, and the other end of the mineralization filter aid 91 is provided with the second end cover 62. One end of the second central passage 92 is connected to the second outlet 332 of the second inner cylinder 33, and the other end of the second central passage 92 is blocked by the second end cover 62.

[0060] In an embodiment of the present application, the filter element assembly 1 can further comprise a first end cover 61, and the filter aid 81 can be provided with a first central passage 82. The first end cover 61 and the first partition 4 are respectively arranged at the two ends of the filter aid 81. One end of the first central passage 82 is blocked by the first end cover 61, and the other end of the first central passage 82 is connected to the first through hole 41.

[0061] In the structure provided in the embodiment, the first central passage 82 can be used to guide the water filtered by the mineralization filter aid 91, so that the water flows into the second containing cavity 9 through the first through hole 41. The first end cover 61 can ensure that the water entering the first central passage 82 is filtered by the filter aid 81, so that the water containing the promoting substances enters the second containing cavity 9 to promote the dissolution of minerals, which can improve the stability and usability of the filter element assembly 1.

[0062] Optionally, the first central passage 82 and the second central passage 92 can be arranged in the axial direction of the filter element assembly 1. Thus, the gravity center of the filter element assembly 1 is balanced, and the structural stability of the filter element assembly 1 is improved.

[0063] Optionally, the first central channel 82 and the second central channel 92 can be arranged along the axial direction of the filter core assembly 1. Thus, the gravity center of the filter core assembly 1 is balanced, and the structural stability is improved.

[0064] Optionally, referring to Figures 2-7 , the filter core assembly 1 can include a docking piece 7. One end of the docking piece 7 is docked with the second outlet 332 or the first outlet 322, and the other end of the docking piece 7 communicates with the water outlet 23. Thus, the water flowing out of the second outlet 332 or the first outlet 322 is guided, and the water outlet 23 is separated from the first water inlet 21 in the outer cylinder 31. Therefore, the water can be smoothly output to the outside of the filter core assembly 1 through the water outlet 23, and the probability of phenomena such as cross flow and backflow is reduced in the overflow state.

[0065] The embodiment provides a mineral water purifier for treating fluid. The mineral water purifier can include a device main body and the filter core assembly 1 as described in any of the above embodiments. The device main body can be docked with the water inlet 22 and the water outlet 23 of the filter core assembly 1, respectively.

[0066] In the structure provided in the embodiment, the promoting filter material 81 and the mineralizing filter material 91 are arranged in series in the inner water channel 2 of the filter core assembly 1. In the overflow state of the filter core assembly 1, the promoting substance in the promoting filter material 81 is dissolved into the water flowing out of the filter core assembly 1. Since the mineralizing filter material 91 is arranged downstream of the promoting filter material 81, the promoting substance flows to the mineralizing filter material 91 with the water, so that the mineral substance in the mineralizing filter material 91 is dissolved into the water flowing out of the filter core assembly 1. Thus, the mineral substance content of the mineral water output by the filter core assembly 1 is improved in the overflow state.

[0067] In the soaking state of the filter core assembly 1, the soaking water in the inner water channel 2 no longer flows through the promoting filter material 81 and then flows through the mineralizing filter material 91. Although the soaking water no longer has a macroscopic flow trend, the mineralizing filter material 91 and the promoting filter material 81 are actually communicated, so that the promoting substance can diffuse in the soaking water to move to the mineralizing filter material 91. Thus, the mineral substance is dissolved into the soaking water, and the mineral substance content of the mineral water output by the filter core assembly 1 is improved in the soaking state. Through the structure of the filter core assembly 1 provided in the embodiment, the mineral substance content of the mineral water is effectively improved in the overflow state and the soaking state, and the probability of insufficient mineral substance content of the mineral water is reduced. Thus, the stability and usability of the mineral water purifier are improved.
