[0033] With the improvement of living quality, people have higher and higher requirements for drinking water, hoping that the water purified by the water purification system can contain minerals that are beneficial to the human body. Therefore, products that use mineralization filters to mineralize purified water are born.

[0034] However, in the related art, when the user does not use water, although the water in the water purification system is no longer output, the mineralized filter element is still immersed in the water, so that the minerals will continue to dissolve into the water. In addition, the water in the mineralized filter element is still connected to the water path of the entire water purification system, so that the minerals in the mineralized filter element will diffuse from the mineralized filter element to the water path of the entire water purification system, causing the water path of the water purification system to exceed the mineral content. As a result, the user will take out a large amount of wastewater with excessive minerals when taking water next time, and the continuous immersion and dissolution will also seriously affect the service life of the mineralized filter element.

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

[0036] See also Figure 1 , Figure 3 to Figure 7 , Figure 1 It is a schematic diagram of the water flow structure of an embodiment of a water system for a mineral water purifier provided in the present application. Figure 3 It is a schematic diagram of the assembly structure of an embodiment of a filter element assembly provided in the present application.

Figure 7 yes Figure 3 A schematic diagram of the cross-sectional structure of the filter element assembly at the fourth angle shown. In order to solve the above technical problems, the specific embodiment of the present application provides a water system 1 for a mineral water purifier for treating water. The water system 1 for a mineral water purifier may include a mineralized filter material 411, a first water inlet valve 11, a water outlet valve 13 and a mineralized waterway 22. The mineralized filter material 411 is arranged in the mineralized waterway 22, and the first water inlet valve 11 and the water outlet valve 13 are connected to the mineralized waterway 22.

[0037] In the preset water flow direction, the first water inlet valve 11 is located upstream of the mineralized filter material 411, and the water outlet valve 13 is located downstream of the mineralized filter material 411. Figures 4 to 7 In the figure, the dotted line with an arrow indicates the part of the preset water flow direction within the filter element assembly 4.

[0038] In the structure provided in this specific embodiment, the mineralized waterway 22 provided with the mineralized filter material 411 is separated from other parts of the waterway system 1 for the mineral water purifier by setting the first water inlet valve 11 and the water outlet valve 13. Since the solubility of minerals in water is limited, the amount of minerals finally dissolved during the soaking process will change with the volume of the water body. Therefore, by controlling the first water inlet valve 11 and the water outlet valve 13 to prevent water from entering and exiting the mineralized waterway 22, it is possible to prevent the minerals in the mineralized filter material 411 from dissolving and diffusing into the waterway system 1 for the mineral water purifier or other water bodies in the outside world during the soaking process, thereby effectively controlling the mineral content when the water is finally discharged to the outside world. When discharging water after soaking, other water bodies that subsequently flow through can dilute the mineralized water containing minerals in the mineralized waterway 22, thereby effectively reducing the probability of excessively high mineral content in the output water body.

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

[0040] In a specific embodiment of the present 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 mineralized cavity 41, and the mineralized cavity 41 is provided with a mineralized water inlet 413 and a mineralized water outlet 414. At least part of the mineralized waterway 22 is arranged in the mineralized cavity 41, and the mineralized filter material 411 is accommodated in the mineralized cavity 41. The first water inlet valve 11 is arranged at the mineralized water inlet 413, and the water outlet valve 13 is arranged at the mineralized water outlet 414. The mineralized water inlet 413 can be opened or closed under the control of the first water inlet valve 11, and the mineralized water outlet 414 can be opened or closed under the control of the water outlet valve 13.

[0041] In the structure provided in this specific embodiment, the filter element assembly 4 is used to form at least a portion of the mineralized water path 22 and accommodate the mineralized filter material 411, and the first water inlet valve 11 and the water outlet valve 13 are set corresponding to the mineralized water inlet 413 and the mineralized water outlet 414 of the mineralization chamber 41. Therefore, by controlling the entry and exit of water in the mineralization chamber 41, it is possible to limit the diffusion of water soaked in the mineralized filter material 411 in the entire water path system 1 for the mineral water purifier, and effectively control the mineral content when the water is finally discharged to the outside.

[0042] In a specific embodiment of the present application, the filter element assembly 4 may also be provided with a pre-chamber 42. The water system 1 for a mineral water purifier may also include a pre-filter material 421, which is accommodated in the pre-chamber 42. When the mineralized water inlet 413 is opened, the pre-chamber 42 and the mineralized chamber 41 are connected. In the preset water flow direction, the pre-chamber 42 is located upstream of the mineralized chamber 41.

[0043] In the structure provided in this specific embodiment, by setting up a pre-chamber 42 and a pre-filter material 421, and utilizing a mineralized water inlet 413 to selectively connect the pre-chamber 42 and the mineralization chamber 41, the water body 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 system 1 used for the mineral water purifier.

[0044] Furthermore, the pre-filter material 421 may not only be used to purify and filter water, but the pre-filter material 421 may also contain a promoting substance, which can promote the dissolution of minerals in the mineralized filter material 411, so that when the water body flows normally, the promoting substance can be used to promote the dissolution of minerals, and the mineral content in the flowing water can be ensured to meet the user's usage requirements under the flowing state.

[0045] Furthermore, the pre-filter material 421 can be used not only to purify and filter water, but the pre-filter material 421 can also contain inhibitory substances, which can inhibit the dissolution of minerals in the mineralization filter material 411. When entering the immersion state, since the water in the mineralization chamber 41 has been filtered by the pre-filter material 421, the inhibitory substances contained therein can inhibit the dissolution of minerals, and can effectively control the dissolution amount of minerals in the immersion water in the immersion state, reduce the probability of excessive dissolution of minerals due to immersion, and make the mineral content in the final output water meet the user's usage requirements.

[0046] In a specific embodiment of the present application, the filter element assembly 4 is arranged vertically, and the front chamber 42 and the mineralization chamber 41 can be arranged along the axial direction B of the filter element assembly 4 , and the front chamber 42 is 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 front chamber 42 is arranged above the mineralization chamber 41. When the first water inlet valve 11 is opened, the water in the front chamber 42 can naturally enter the mineralization chamber 41 under the guidance of gravity, thereby guiding the flow direction of the water in the filter element assembly 4.

[0048] In a specific embodiment of the present application, the filter element assembly 4 may include an outer shell 43 and an inner shell 44, wherein the outer shell 43 is provided with a first cavity 431, a first water inlet 432, and a first water outlet 433. The inner shell 44 is disposed in the first cavity 431, the front cavity 42 is disposed between the inner shell 44 and the inner wall of the first cavity 431, and the first water inlet 432 is connected to the front cavity 42. The mineralized cavity 41 may be disposed on the side of the inner shell 44 away from the first cavity 431, the mineralized water inlet 413 is disposed at the upper end of the inner shell 44, the mineralized water outlet 414 is disposed at the lower end of the inner shell 44, and the first water outlet 433 is connected to the mineralized water outlet 414.

[0049] In the structure provided in this specific embodiment, the outer shell 43 and the inner shell 44 are used to cooperate with each other to isolate the front chamber 42 from the outside, and the mineralization chamber 41 is isolated from the front chamber 42. The positions of the mineralization water inlet 413, the mineralization water outlet 414 and the first water outlet 433 are set corresponding to the upper and lower position relationship between the front chamber 42 and the mineralization chamber 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 for the mineral water purifier.

[0050] In a specific embodiment of the present application, the pre-filter material 421 may be provided with a first central channel 422, the filter element assembly 4 includes a first end cap 45, and the first central channel 422 is arranged along the axial direction B. The mineralized water inlet 413 is connected to the lower end of the first central channel 422, and the first end cap 45 is set to block the upper end of the first central channel 422. Optionally, the mineralized filter material 411 may be provided with a second central channel 412, the filter element assembly 4 includes a second end cap 46, and the second central channel 412 is arranged along the axial direction B. The mineralized water outlet 414 is connected to the lower end of the second central channel 412, and the second end cap 46 is set to block 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 mineralized filter material 411 can be arranged in a manner of cooperating with a central channel and an end cover. The end cover can separate the central channel from the water body around the filter material, so that when the water body needs to enter the mineralized water inlet 413 or the mineralized water outlet 414 through the central channel, it must first be filtered by the pre-filter material 421 or the mineralized filter material 411, thereby ensuring the stability of the water quality of the output water body.

[0052] See also Figure 7 In a specific embodiment of the present 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, and 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, and the filter element assembly 4 may include a second water inlet valve 12, and the second water inlet valve 12 is provided at the second water inlet 434 and / or the third water inlet 441. The second water inlet 434 and / or the third water inlet 441 can be opened or closed under the control of the second water inlet valve 12.

[0053] In the structure provided in this specific embodiment, through the docking relationship between the second water inlet 434 and the third water inlet 441, water can be directly introduced into the mineralization chamber 41 without passing through the pre-chamber 42, thereby improving the usability of the water system 1 for the mineral water purifier. In the case where the pre-filter material 421 contains a promoting substance, by controlling the first water inlet valve 11 and the second water inlet valve 12, the content of the promoting substance in the mineralization chamber 41 can be controlled, thereby controlling the dissolution amount of the minerals.

[0054] Among them, the second water inlet valve 12 can be a one-way valve. Specifically, the second water inlet valve 12 can be arranged in the second water inlet 434. A third sealing strip 121 can be provided at one end of the second water inlet 434 away from the third water inlet 441. The third sealing strip 121 is formed in a ring shape, and the ring-shaped third sealing strip 121 can protrude into the second water inlet 434 vertically along the axial direction B, so that the inner diameter of the end of the second water inlet 434 away from the third water inlet 441 is smaller than the outer diameter of the second water inlet valve 12, and the inner diameter of the end of the second water inlet 434 docking with the third water inlet 441 is larger than the outer diameter of the second water inlet valve 12.

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

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

[0057] See also Figure 2 , Figure 2 1 is a schematic diagram of the water flow structure of another embodiment of the water system for a mineral water purifier provided by the present application. In a specific embodiment of the present application, the water system 1 for a mineral water purifier may also include a front waterway 21 and a water outlet 23. The first water inlet valve 11 connects the front waterway 21 and the mineralized waterway 22, and the water outlet valve 13 connects the mineralized waterway 22 and the water outlet 23.

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

[0059] Furthermore, the front water channel 21 can not only be used to purify and filter water, but the front water channel 21 can also contain a promoting substance, which can promote the dissolution of minerals in the mineralized water channel 22, so that when the water body flows normally, the promoting substance can be used to promote the dissolution of minerals, and it can ensure that the mineral content in the flowing water meets the user's usage requirements under the flowing state.

[0060] Furthermore, the front water channel 21 can be used not only to purify and filter water, but the front water channel 21 can also contain inhibitory substances, which can inhibit the dissolution of minerals in the mineralization water channel 22. When entering the immersion state, since the water in the mineralization chamber 41 has been filtered by the front water channel 21, the inhibitory substances contained therein can inhibit the dissolution of minerals, and can effectively control the dissolution amount of minerals in the immersion water in the immersion state, reduce the probability of excessive dissolution of minerals due to immersion, and make the mineral content in the final output water meet the user's usage requirements.

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

[0062] Optionally, the water system 1 for a mineral water purifier may further include a reflux valve 14 , which is connected to the reflux waterway 24 , so as to control the water to flow to the input end of the water purification unit 3 through the reflux water flow.

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

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

[0065] In order to solve the above-mentioned technical problems, the specific implementation of the present application also provides a mineral water purifier, including a water outlet component and a water system 1 for a mineral water purifier as described in any one of the above-mentioned specific implementations, 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 a mineral water purifier.

[0066] In the structure provided in this specific embodiment, the mineralized waterway 22 provided with the mineralized filter material 411 is separated from other parts of the waterway system 1 for the mineral water purifier by setting the first water inlet valve 11 and the water outlet valve 13. Since the solubility of minerals in water is limited, the amount of minerals finally dissolved during the soaking process will change with the volume of the water body. Therefore, by controlling the first water inlet valve 11 and the water outlet valve 13 to prevent water from entering and exiting the mineralized waterway 22, it is possible to prevent the minerals in the mineralized filter material 411 from dissolving and diffusing into the waterway system 1 for the mineral water purifier or other water bodies in the outside world during the soaking process, thereby effectively controlling the mineral content when the water is finally discharged to the outside world. When discharging water after soaking, other water bodies that subsequently flow through can dilute the mineralized water containing minerals in the mineralized waterway 22, thereby effectively reducing the probability of excessively high mineral content in the water body output by the water outlet component.

[0067] See also Figure 8-Figure 9 , Figure 8 yes Figure 4 Schematic diagram of the enlarged structure of area A in the middle. Fig. 9 1 is a schematic diagram of a cross-sectional explosion structure of an embodiment of the first water inlet valve provided by the present application. The first water inlet valve 11 may include a compression spring 111, a movable part 112, a valve body 113, a first sealing strip 116 and a second sealing strip 117. The movable part 112 may include a connecting rod 112a and a blocking head 112b, and the connecting rod 112a is coaxially connected with the blocking head 112b. The valve body body 113 is provided with a valve body inlet 114 and a valve body outlet 115, and the valve body inlet 114 and the valve body outlet 115 are coaxially connected, and the valve body inlet 114, the valve body outlet 115, are coaxial with the connecting rod 112a and the blocking head 112b. When not assembled with the movable part 112, the valve body inlet 114 is connected to the valve body outlet 115, the valve body inlet 114 is connected to the front chamber 42, and the valve body outlet 115 is connected to the mineralization chamber 41. The inner diameter of the end of the valve body inlet 114 away from the valve body outlet 115 is smaller than the inner diameter of the end of the valve body inlet 114 close 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, and the latter is larger than the outer diameter of the blocking head 112b. When the movable member 112 moves to the end of the valve body inlet 114 away 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 front chamber 42 from the mineralization chamber 41.

[0068] The valve body outlet 115 and the connecting rod 112a can be movably connected, and when the connecting rod 112a is inserted into the valve body outlet 115, the fluid can pass through the valve body outlet 115. The contour shape of the cross section of the valve body outlet 115 perpendicular to the axial direction B of the valve body outlet 115 can be different from the contour 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 in the cross section is greater than the radial dimension of the connecting rod 112a on the same cross section.

[0069] The compression spring 111 is sleeved on the outer circumference of the connecting rod 112a. When the movable member 112 moves toward the valve body outlet 115, the compression spring 111 can abut between the valve body main body 113 and the blocking head 112b on the side of the valve body outlet 115. When the first water inlet valve 11 is controlled to be closed, the compression spring 111 can be restored under the action of elasticity to push the blocking head 112b to block the valve body inlet 114.

[0070] The first sealing strip 116 is sleeved on the outer periphery of the valve body 113 , and the valve body 113 is installed at the mineralization water inlet 413 of the inner shell 44 . The first sealing strip 116 can press against the inner shell 44 on the side of the valve body 113 , thereby fixing the first valve body and isolating the front chamber 42 from the mineralization chamber 41 .

[0071] The second sealing strip 117 can be sleeved on the outer periphery of the blocking head 112b. When the movable member 112 moves to the end of the blocking head 112b abutting against the valve body inlet 114 away from the valve body outlet 115, the second sealing strip 117 abuts between the blocking head 112b and the valve body 113, thereby closing the first water inlet valve 11 and isolating the pre-chamber 42 from the mineralization chamber 41.

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

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

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

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

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