Description

Technical Field

[0001] This application relates to the field of water treatment equipment technology, specifically to a water circuit system for a mineral water purifier and a mineral water purifier. Background Technology

[0002] As living standards improve, people have higher and higher requirements for drinking water, hoping that the water purified by water purification systems will contain minerals beneficial to the human body. Therefore, products that use mineralizing filter cartridges to mineralize purified water have emerged.

[0003] However, in related technologies, even when the user is not using water, although the water purification system no longer outputs water, the mineralizing filter cartridge remains submerged, allowing minerals to continue dissolving into the water. Furthermore, the water in the mineralizing filter cartridge remains connected to the entire water purification system's circuitry, causing minerals to diffuse from the filter cartridge throughout the system, leading to excessive mineral levels in the water. This results in the user drawing large amounts of wastewater with excessive minerals the next time they use water, and the continued leaching and dissolution severely impacts the lifespan of the mineralizing filter cartridge.

When water is discharged after soaking, the subsequent flow of other water bodies can dilute the mineralized water containing minerals in the mineralized water path, thereby effectively reducing the probability of excessively high mineral content in the output water.

[0032] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0033] As living standards improve, people have higher and higher requirements for drinking water, hoping that the water purified by water purification systems will contain minerals beneficial to the human body. Therefore, products that use mineralizing filter cartridges to mineralize purified water have emerged.

[0034] However, in related technologies, even when the user is not using water, although the water purification system no longer outputs water, the mineralizing filter cartridge remains submerged, allowing minerals to continue dissolving into the water. Furthermore, the water in the mineralizing filter cartridge remains connected to the entire water purification system's circuitry, causing minerals to diffuse from the filter cartridge throughout the system, leading to excessive mineral levels in the water. This results in the user drawing large amounts of wastewater with excessive minerals the next time they use water, and the continued leaching and dissolution severely impacts the lifespan of the mineralizing filter cartridge.

[0035] In order to improve or solve the above technical problems, the inventors of this application, after long-term research, have proposed at least the following embodiments.

[0036] See Figure 1 , Figures 3-7 , Figure 1 This is a schematic diagram of the water flow structure of an embodiment of the water system for a mineral water purifier provided in this application. Figure 3 This is a schematic diagram of the assembly structure of an embodiment of the filter element assembly provided in this application. Figure 4 yes Figure 3 The diagram shows a cross-sectional view of the filter assembly from the first angle. Figure 5 yes Figure 3 The diagram shows a cross-sectional view of the filter assembly from a second angle. Figure 6 yes Figure 3 The diagram shows a cross-sectional view of the filter assembly from the third angle. Figure 7 yes Figure 3 The diagram shows a cross-sectional view of the filter assembly from a fourth angle. To address the aforementioned technical problems, this application provides a water system 1 for a mineral water purifier, used for water treatment. The water system 1 for the mineral water purifier may include mineralizing filter material 411, a first inlet valve 11, an outlet valve 13, and a mineralizing water passage 22. The mineralizing filter material 411 is disposed within the mineralizing water passage 22, and the first inlet valve 11 and the outlet valve 13 are connected to the mineralizing water passage 22.

[0037] In the preset water flow direction, the first inlet valve 11 is located upstream of the mineralized filter media 411, and the outlet valve 13 is located downstream of the mineralized filter media 411. Figures 4-7 In the middle, the portion of the filter element assembly 4 with the preset water flow direction is indicated by a dotted line with an arrow.

[0038] In the structure provided in this specific embodiment, by using a first inlet valve 11 and an outlet valve 13, the mineralized water path 22, which contains the mineralized filter material 411, is separated from other parts of the water system 1 used for the mineral water purifier. Since the solubility of minerals in water is limited, the amount of minerals dissolved during soaking changes with the volume of the water. Therefore, by controlling the first inlet valve 11 and the outlet valve 13 to prevent water from entering or leaving the mineralized water path 22, the minerals in the mineralized filter material 411 can be prevented from dissolving and diffusing into the water system 1 used for the mineral water purifier or into other water bodies outside during soaking, effectively controlling the mineral content of the final water discharged to the outside. When water is discharged after soaking, the subsequent flow of other water bodies can dilute the mineralized water containing minerals in the mineralized water path 22, thereby effectively reducing the probability of excessively high mineral content in the output water.

[0039] The output water body can be considered as the mineral-containing water body that the water system 1 of the mineral water purifier outputs to the outside world to provide to the user when the user takes water. Mineralized water can refer to water containing minerals.

[0040] In one specific embodiment of this application, the water system 1 for a mineral water purifier may include a filter element assembly 4. The filter element assembly 4 is provided with a mineralization chamber 41, which has a mineralization inlet 413 and a mineralization outlet 414. At least a portion of the mineralization water path 22 is disposed within the mineralization chamber 41, and the mineralization filter material 411 is accommodated within the mineralization chamber 41. A first inlet valve 11 is disposed at the mineralization inlet 413, and an outlet valve 13 is disposed at the mineralization outlet 414. The mineralization inlet 413 can be opened or closed under the control of the first inlet valve 11, and the mineralization outlet 414 can be opened or closed under the control of the outlet valve 13.

[0041] In the structure provided in this specific embodiment, the filter element assembly 4 forms at least a partial mineralized water path 22 and accommodates the mineralized filter material 411. The first water inlet valve 11 and the water outlet valve 13 are set to correspond to the mineralized water inlet 413 and the mineralized water outlet 414 of the mineralized chamber 41. In this way, by controlling the inflow and outflow of water in the mineralized chamber 41, the diffusion of water soaked with the mineralized filter material 411 in the entire water system 1 for the mineral water purifier can be limited, and the mineral content of the final water discharged to the outside can be effectively controlled.

[0042] In one specific embodiment of this application, the filter element assembly 4 may also be provided with a pre-filter chamber 42. The water system 1 for the mineral water purifier may also include a pre-filter material 421, which is housed within the pre-filter chamber 42. When the mineralization inlet 413 is open, it connects the pre-filter chamber 42 and the mineralization chamber 41. In a preset water flow direction, the pre-filter chamber 42 is located upstream of the mineralization chamber 41.

[0043] In the structure provided in this specific embodiment, by setting a pre-filter chamber 42 and a pre-filter material 421, and selectively connecting the pre-filter chamber 42 and the mineralization chamber 41 using a mineralization inlet 413, the water can be filtered by the pre-filter material 421 before entering the mineralization chamber 41 to be mineralized, thereby improving the water quality of the mineralized water output to the outside by the water circuit system 1 of the mineral water purifier.

[0044] Furthermore, the pre-filter material 421 can not only be used to purify and filter water, but also contain promoting substances. These promoting substances can promote the dissolution of minerals in the mineralized filter material 411. Thus, when the water flows normally, the promoting substances can promote the dissolution of minerals, ensuring that the mineral content in the flowing water meets the user's needs.

[0045] Furthermore, the pre-filter material 421 can not only be used to purify and filter water, but also contain inhibitory substances. These inhibitory substances can inhibit the dissolution of minerals in the mineralization filter material 411. When entering the soaking state, since the water in the mineralization chamber 41 has already been filtered by the pre-filter material 421, the inhibitory substances contained therein can inhibit the dissolution of minerals. This can effectively control the amount of minerals dissolved in the soaking water during the soaking state, reduce the probability of excessive mineral dissolution during soaking, and ensure that the mineral content in the final output water meets the user's needs.

[0046] In one specific embodiment of this application, the filter element assembly 4 is arranged vertically, and the pre-positioning chamber 42 and the mineralization chamber 41 can be arranged along the axial direction B of the filter element assembly 4, with the pre-positioning chamber 42 located above the mineralization chamber 41.

[0047] In the structure provided in this specific embodiment, the filter element assembly 4 is arranged vertically, and the pre-filter chamber 42 is arranged above the mineralization chamber 41. When the first water inlet valve 11 is opened, the water in the pre-filter chamber 42 can be naturally guided into the mineralization chamber 41 under the action of gravity, thereby guiding the flow direction of the water in the filter element assembly 4.

[0048] In one specific embodiment of this application, the filter element assembly 4 may include an outer shell 43 and an inner shell 44. The outer shell 43 is provided with a first cavity 431, a first inlet 432, and a first outlet 433. The inner shell 44 is disposed within the first cavity 431, and a pre-filter cavity 42 is disposed between the inner shell 44 and the inner wall of the first cavity 431. The first inlet 432 is connected to the pre-filter cavity 42. The mineralization cavity 41 may be disposed on the side of the inner shell 44 opposite to the first cavity 431. The mineralization inlet 413 is disposed at the upper end of the inner shell 44, and the mineralization outlet 414 is disposed at the lower end of the inner shell 44. The first outlet 433 is connected to the mineralization outlet 414.

[0049] In the structure provided in this specific embodiment, the outer shell 43 and the inner shell 44 are fitted together to isolate the pre-cavity 42 from the outside and to isolate the mineralization cavity 41 from the pre-cavity 42. The positions of the mineralization inlet 413, the mineralization outlet 414 and the first outlet 433 are set according to the vertical position relationship between the pre-cavity 42 and the mineralization cavity 41, which meets the working requirements of the filter element assembly 4 and can improve the availability and stability of the water system 1 used in the mineral water purifier.

[0050] In one specific embodiment of this application, the pre-filter material 421 may be provided with a first central channel 422, and the filter element assembly 4 includes a first end cap 45. The first central channel 422 is arranged along the axial direction B. The mineralization inlet 413 is connected to the lower end of the first central channel 422, and the first end cap 45 is used to cover and seal the upper end of the first central channel 422. Optionally, the mineralization filter material 411 may be provided with a second central channel 412, and the filter element assembly 4 includes a second end cap 46. The second central channel 412 is arranged along the axial direction B. The mineralization outlet 414 is connected to the lower end of the second central channel 412, and the second end cap 46 is used to cover and seal the upper end of the second central channel 412.

[0051] In the structure provided in this specific embodiment, both the pre-filter material 421 and the mineralization filter material 411 can be set up by using a central channel and an end cap. The end cap can separate the central channel from the water body around the filter material, so that when the water body needs to enter the mineralization inlet 413 or the mineralization outlet 414 through the central channel, it must first be filtered by the pre-filter material 421 or the mineralization filter material 411, thereby ensuring the stability of the water quality of the output water body.

[0052] See Figure 7 In one specific embodiment of this application, the outer shell 43 may be provided with a second water inlet 434, and the inner shell 44 may be provided with a third water inlet 441. The second water inlet 434 is connected to the third water inlet 441. The third water inlet 441 is connected to the mineralization chamber 41. The filter element assembly 4 may include a second water inlet valve 12, which is disposed at the second water inlet 434 and / or the third water inlet 441. This allows the second water inlet 434 and / or the third water inlet 441 to be opened or closed under the control of the second water inlet valve 12.

[0053] In the structure provided in this specific embodiment, the connection between the second inlet 434 and the third inlet 441 allows water to be introduced directly into the mineralization chamber 41, bypassing the pre-filter chamber 42, thereby improving the usability of the water system 1 used in the mineral water purifier. If the pre-filter material 421 contains a promoting substance, the content of this promoting substance in the mineralization chamber 41 can be controlled by controlling the first inlet valve 11 and the second inlet valve 12, thereby controlling the amount of minerals dissolved.

[0054] The second inlet valve 12 can be a one-way valve. Specifically, the second inlet valve 12 can be installed in the second inlet 434. A third sealing strip 121 can be provided at the end of the second inlet 434 away from the third inlet 441. The third sealing strip 121 is annular and protrudes vertically into the second inlet 434 along the axial direction B, such that the inner diameter of the end of the second inlet 434 away from the third inlet 441 is smaller than the outer diameter of the second inlet valve 12, and the inner diameter of the end of the second inlet 434 that connects to the third inlet 441 is larger than the outer diameter of the second inlet valve 12.

[0055] When water is supplied from the outside to the mineralization chamber 41 through the second inlet 434, the second inlet valve 12 can move towards the end of the second inlet 434 that is connected to the third inlet 441 under the impact of the water flow, so that the second inlet valve 12 is separated from the third sealing strip 121, and the water can flow into the mineralization chamber 41 through the gap between the second inlet valve 12 and the second inlet 434.

[0056] When the external environment stops supplying water to the mineralization chamber 41 through the second inlet 434, the second inlet valve 12, under the pressure of the water in the mineralization chamber 41, pushes against the third sealing strip 121, thereby closing the second inlet 434 and isolating the mineralization chamber 41 from the outside environment. This allows water to enter the mineralization chamber 41 directly while reducing the probability of water containing minerals flowing back at the second inlet 434.

[0057] See Figure 2 , Figure 2 This is a schematic diagram of the water flow structure of another embodiment of the water system for a mineral water purifier provided in this application. In a specific embodiment of this application, the water system 1 for the mineral water purifier may further include a pre-filter water path 21 and an outlet water path 23. A first inlet valve 11 connects the pre-filter water path 21 and the mineralized water path 22, and an outlet valve 13 connects the mineralized water path 22 and the outlet water path 23.

[0058] In the structure provided in this specific embodiment, in addition to the scheme of setting the pre-filter material 421 and the mineralization filter material 411 in the same filter element, a pre-filter water path 21 for pre-filtering and purifying water can also be set separately. The pre-filter water path 21 and the mineralization water path 22 are separated by the first inlet valve 11. The pre-filter water path 21 can also be used to filter and purify the water entering the mineralization water path 22, thereby improving the water quality of the mineralized water output to the outside by the water system 1 of the mineral water purifier.

[0059] Furthermore, the pre-filter 21 can not only be used to purify and filter water, but can also contain a promoting substance. This promoting substance can promote the dissolution of minerals in the mineralization channel 22. Thus, when the water flows normally, the promoting substance can promote the dissolution of minerals, ensuring that the mineral content in the flowing water meets the user's needs.

[0060] Furthermore, the pre-filter 21 can not only be used to purify and filter water, but also contain inhibitors. These inhibitors can suppress the dissolution of minerals in the mineralization channel 22. When the water enters the soaking state, since the water in the mineralization chamber 41 has already been filtered by the pre-filter 21, the inhibitors it contains can suppress the dissolution of minerals. This effectively controls the amount of minerals dissolved in the soaking water, reduces the probability of excessive mineral dissolution during soaking, and ensures that the mineral content in the final output water meets the user's needs.

[0061] In one specific embodiment of this application, the water system 1 for the mineral water purifier may further include a return water path 24 and a water purification unit 3, with one end of the water purification unit 3 and the return water path 24 connected to the pre-flow water path 21. In a preset water flow direction, the water purification unit 3 may be located upstream of one end of the return water path 24, and the other end of the return water path 24 is connected to the input end of the water purification unit 3.

[0062] Optionally, the water system 1 for the mineral water purifier may also include a return valve 14 connected to the return water path 24, thereby controlling the water to flow to the input end of the water purification unit 3 through the return water flow.

[0063] Optionally, the first inlet valve 11 may include a three-way valve, which connects the pre-flow water path 21, the return water path 24, and the mineralization water path 22, so that the three-way valve can be used to control the flow of water between the pre-flow water path 21, the return water path 24, and the mineralization water path 22.

[0064] In the structure provided in this specific embodiment, by setting up a return water path 24, the water in the pre-filter water path 21 can be returned to the water purification unit 3 for another purification process. When minerals have diffused into the water in the pre-filter water path 21, the return water path 24 can be used to purify this part of the water again to remove these minerals, thereby reducing the probability that the mineral content in the water finally output to the outside by the water system 1 of the mineral water purifier exceeds the standard.

[0065] To solve the above-mentioned technical problems, this application also provides a mineral water purifier, including a water outlet component and a water system 1 for the mineral water purifier as described in any of the above embodiments. The water outlet component is used to discharge water to the outside, and the water outlet component is connected to the water outlet 23 of the water system 1 for the mineral water purifier.

[0066] In the structure provided in this specific embodiment, by using a first inlet valve 11 and an outlet valve 13, the mineralized water path 22, which contains the mineralized filter material 411, is separated from other parts of the water system 1 used for the mineral water purifier. Since the solubility of minerals in water is limited, the amount of minerals dissolved during soaking changes with the volume of the water. Therefore, by controlling the first inlet valve 11 and the outlet valve 13 to prevent water from entering or leaving the mineralized water path 22, the minerals in the mineralized filter material 411 can be prevented from dissolving and diffusing into the water system 1 used for the mineral water purifier or into other water bodies outside during soaking, effectively controlling the mineral content of the final water discharged to the outside. When water is discharged after soaking, the subsequent flow of other water can dilute the mineralized water containing minerals in the mineralized water path 22, thereby effectively reducing the probability of excessively high mineral content in the water output from the outlet component.

[0067] See Figures 8-9 , Figure 8 yes Figure 4 A magnified structural diagram of region A in the middle. Figure 9 This is a cross-sectional exploded structural diagram of an embodiment of the first water inlet valve provided in this application. The first water inlet valve 11 may include a compression spring 111, a movable member 112, a valve body 113, a first sealing strip 116, and a second sealing strip 117. The movable member 112 may include a connecting rod 112a and a blocking head 112b, with the connecting rod 112a and the blocking head 112b coaxially connected. The valve body 113 has a valve body inlet 114 and a valve body outlet 115, which are coaxially connected and coaxial with the connecting rod 112a and the blocking head 112b. When not assembled with the movable member 112, the valve body inlet 114 communicates with the valve body outlet 115, with the valve body inlet 114 connected to the pre-cavity 42 and the valve body outlet 115 connected to the mineralization cavity 41. The inner diameter of the end of the valve body inlet 114 furthest from the valve body outlet 115 is smaller than the inner diameter of the end of the valve body inlet 114 closest to the valve body outlet 115, and the former is smaller than the outer diameter of the blocking head 112b of the movable member 112, while the latter is larger than the outer diameter of the blocking head 112b. When the movable member 112 moves to the point where the blocking head 112b abuts against the end of the valve body inlet 114 furthest from the valve body outlet 115, the blocking head 112b can block the valve body inlet 114, thereby closing the first water inlet valve 11 and isolating the pre-treatment chamber 42 from the mineralization chamber 41.

[0068] The valve body outlet 115 and the connecting rod 112a are movably connected. When the connecting rod 112a is inserted into the valve body outlet 115, fluid can pass through the valve body outlet 115. The profile shape of the cross-section of the valve body outlet 115 perpendicular to the axial direction B of the valve body outlet 115 may differ from the profile shape of the connecting rod 112a on the same cross-section, and the radial dimension of the valve body outlet 115 in at least one direction on this cross-section is greater than the radial dimension of the connecting rod 112a on the same cross-section.

[0069] A compression spring 111 is sleeved on the outer periphery of the connecting rod 112a. When the movable part 112 moves towards the valve body outlet 115, the compression spring 111 can abut against the valve body body 113 and the blocking head 112b on the periphery of the valve body outlet 115. When the first water inlet valve 11 is closed, the compression spring 111 can return to its original position under elastic action, thereby pushing the blocking head 112b to block the valve body inlet 114.

[0070] The first sealing strip 116 is fitted around the outer periphery of the valve body 113. The valve body 113 is installed at the mineralization inlet 413 of the inner shell 44. The first sealing strip 116 can abut against the inner shell 44 around the valve body 113, thereby fixing the first valve body and isolating the pre-cavity 42 from the mineralization cavity 41.

[0071] The second sealing strip 117 can be fitted around the outer periphery of the blocking head 112b. When the movable part 112 moves to the end of the blocking head 112b that is far from the valve body outlet 115 at the valve body inlet 114, the second sealing strip 117 abuts between the blocking head 112b and the valve body body 113, thereby closing the first water inlet valve 11 and isolating the pre-positioning chamber 42 from the mineralization chamber 41.

[0072] Optionally, the above description only takes the first water inlet valve 11 as an example. The second water inlet valve 12, the water outlet valve 13, and the return valve 14 can also adopt similar structures, which will not be described in detail later.

[0073] Optionally, the water system 1 for the mineral water purifier may include a controller, which is connected to at least one of the first inlet valve 11, the second inlet valve 12, the outlet valve 13, and the return valve 14. The controller is used to control the opening or closing of the valve body connected thereto.

[0074] Optionally, the water system 1 for the mineral water purifier may include a pre-inlet water circuit, which may be connected to a pump and a pre-inlet valve. One end of the pre-inlet water circuit is connected to an external water source, and the other end is used to connect to the input end of the water purification unit 3. The pre-inlet valve can be used to control the opening and closing of the pre-inlet water circuit.

[0075] Furthermore, the pre-installed water inlet valve can control the flow rate and velocity of external water entering the water purification unit 3. The pump body can be used to pump fluid, thereby causing the water to flow in the water circuit system 1 of the mineral water purifier along a preset water flow direction.

[0076] Optionally, the water system 1 for the mineral water purifier may include a wastewater path, which may be connected to a wastewater valve. The water purification unit 3 may be an RO (reverse osmosis) water purifier, with one end of the wastewater path connected to the outside and the other end connected to the waste outlet of the RO water purifier. When purifying raw water input from the outside, the water purification unit 3 can output purified water with a lower impurity content than the raw water to the pre-water path 21, and then discharge concentrated water with a higher impurity content than the raw water to the outside through the wastewater path. The wastewater valve can be used to control the opening and closing of the wastewater path and can control the timing of the discharge of concentrated water.
