Description

Technical Field

[0001] This application relates to the field of water treatment equipment technology, specifically to filter cartridges and mineral water purifiers. 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, there are two common methods for preparing mineralized water. The first is to artificially mix mineral salts with water to create mineralized water of appropriate concentration. However, this method is very cumbersome, requires a certain level of chemical knowledge, and is relatively inefficient. The second method involves adding mineral-containing minerals to a container filled with water—such as a water dispenser or water purifier. The mineral salts in the minerals dissolve into the water in the container, transforming it into mineralized water. However, it is difficult to effectively control the mineral content of mineralized water prepared using this method. If the mineral content exceeds the standard, it can have negative effects on the user. Utility Model Content

[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, there are two common methods for preparing mineralized water. The first is to artificially mix mineral salts with water to create mineralized water of appropriate concentration. However, this method is very cumbersome, requires a certain level of chemical knowledge, and is inefficient. The second method involves adding mineral-containing minerals to a container filled with water—such as a water dispenser or non-mineralized water purifier. The mineral salts in the minerals dissolve into the water in the container, transforming it into mineralized water. However, it is difficult to effectively control the mineral content of mineralized water prepared using this method. If the mineral content exceeds the standard, it can have negative effects on the user.

[0032] 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.

[0033] See Figures 1-3 , Figure 1 This is a schematic diagram of the assembly structure of the filter element assembly provided in this application from one angle. Figure 2 This is a cross-sectional structural diagram of an embodiment of the filter element assembly provided in this application. Figure 3 This is a cross-sectional structural schematic diagram of another embodiment of the filter element assembly provided in this application. Specific embodiments of this application provide a filter element assembly 1 for treating fluids. The filter element assembly 1 may include mineralized filter media 111 and non-mineralized filter media 121.

[0034] The filter element assembly 1 has a first chamber 11 and a second chamber 12. The first chamber 11 has a first inlet 112 and a first outlet 113, and the second chamber 12 has a second inlet 122 and a second outlet 123. Mineralized filter media 111 is disposed in the first chamber 11, and non-mineralized filter media 121 is disposed in the second chamber 12. The filter element assembly 1 has a mineralized water path through which the mineralized filter media 111 flows and a non-mineralized water path through which the non-mineralized filter media 121 flows. The mineralized water path and the non-mineralized water path are arranged in parallel, or the mineralized water path can be connected to the non-mineralized water path through a branch water path 22.

[0035] In the structure provided in this specific embodiment, by connecting the mineralized water path and the non-mineralized water path in parallel, or by connecting the mineralized water path to the non-mineralized water path through the diversion water path 22, the mineralized water flowing through the mineralized filter material 111 and the non-mineralized water flowing through the non-mineralized filter material 121 can be mixed together. This allows the non-mineralized water to dilute the mineralized water, reducing the probability that the mineral content of the final water output from the filter element assembly 1 is too high, thereby improving the safety and stability of the filter element assembly 1.

[0036] Optionally, the mineralized filter media 111 may also contain at least one of the following mineral elements: zinc, calcium, magnesium, etc. These mineral elements can exist in the form of salts and have a certain degree of water solubility. The non-mineralized filter media 121 may specifically be an adsorption filter media, capable of adsorbing and purifying and / or filtering water flowing through a non-mineralized water path.

[0037] In one specific embodiment of this application, mineralized filter material 111 and non-mineralized filter material 121 are respectively disposed in the first cavity 11 and the second cavity 12 along the axial direction of the filter element assembly 1.

[0038] The filter element assembly 1 also includes a housing 13 and an isolation assembly 14. A second cavity 12 is disposed within the housing 13, and the isolation assembly 14 is disposed within the second cavity 12. A first cavity 11 is disposed within the isolation assembly 14. A first inlet 112, a first outlet 113, a second inlet 122, and a second outlet 123 are disposed within the housing 13.

[0039] The mineralized water passage includes a first internal water passage 15 and a second internal water passage 16, while the non-mineralized water passage includes a third internal water passage 17 and a fourth internal water passage 18. One end of the first internal water passage 15 is connected to the second inlet 122, and the other end is connected to the second cavity 12. One end of the second internal water passage 16 is connected to the second outlet 123, and the other end is connected to the second cavity 12. One end of the third internal water passage 17 is connected to the first inlet 112, and the other end is connected to the first cavity 11. One end of the fourth internal water passage 18 is connected to the first outlet 113, and the other end is connected to the first cavity 11.

[0040] The structure provided in this specific embodiment uses the isolation component 14 to isolate the first cavity 11 and the second cavity 12, realizing the parallel setting of the mineralized water path and the non-mineralized water path. In this way, the non-mineralized water flowing out of the non-mineralized water path can be used to dilute the mineralized water flowing out of the mineralized water path, reducing the probability that the mineral content of the final water output from the filter element assembly 1 is too high, thereby improving the safety and stability of the filter element assembly 1.

[0041] In one specific embodiment of this application, the isolation assembly 14 includes an annular isolation body 143 and a central tube 144, with the central tube 144 arranged along the axial direction of the filter element assembly 1. The annular isolation body 143 is sleeved on the outer periphery of the lower end of the central tube 144, and the non-mineralized filter material 121 is sleeved on the outer periphery of the upper end of the central tube 144. A second inner water passage 16 is disposed inside the central tube 144, and the non-mineralized filter material 121 is disposed between the second inner water passage 16 and the second inlet 122.

[0042] With the structure provided in this specific embodiment, the annular isolation body 143 and the non-mineralized filter material 121 are respectively fitted onto the lower and upper sections of the central tube 144. The second cavity 12 and the first cavity 11 are coaxially arranged from top to bottom, forming a symmetrical and balanced structure in the filter element assembly 1. The central tube 144 connects the water outlet component and the second cavity 12, so that the fluid flowing out of the second water outlet 123 can be filtered by the non-mineralized filter material 121, which can improve the stability of the filter element assembly 1.

[0043] Optionally, the housing 13 may include a first docking portion 131 and a second docking portion 132. The first docking portion 131 and the second docking portion 132 are disposed on the side surface of the housing 13 facing the interior of the second cavity 12. The isolation assembly 14 docks with the first docking portion 131 and the second docking portion 132, wherein the first docking portion 131 connects the first cavity 11 and the first water inlet 112, and the second docking portion 132 connects the first cavity 11 and the first water outlet 113.

[0044] like Figure 2 As shown, the central tube 144 may include a crossbar, with a first cavity 11 and a second cavity 12 respectively disposed on both sides of the crossbar. A central channel is provided within the non-mineralized filter material 121, and the upper end of the central tube 144 is fitted into this central channel. The housing 13 may include an end cap, which is disposed on one end of the non-mineralized filter material 121 to block one end of the central channel. The end of the non-mineralized filter element away from the end cap abuts against the crossbar. The mineralized filter material 111 abuts against the crossbar and the annular isolation body 143 along the circumference of the central tube 144.

[0045] Optionally, the annular isolation body 143 may include a third docking portion 141 and a fourth docking portion 142. The third docking portion 141 can be sleeved with the first docking portion 131, and the fourth docking portion 142 can be sleeved with the second docking portion 132, thereby docking the annular isolation body 143 with the housing 13.

[0046] Optionally, the housing 13 may also include a fifth docking portion 133, which can be sleeved with the lower end of the central tube 144, thereby docking the central tube 144 with the housing 13.

[0047] This application provides a mineral water purifier, including a main body and a filter element assembly 1 as described in any of the above embodiments, wherein the main body can be connected to the filter element assembly 1.

[0048] In the structure provided in this specific embodiment, the mineralized water passage and the non-mineralized water passage are arranged in parallel in the filter element assembly 1, or the mineralized water passage is connected to the non-mineralized water passage through the diversion water passage 22. This allows the mineralized water flowing through the mineralized filter media 111 and the non-mineralized water flowing through the non-mineralized filter media 121 to be mixed together. This allows the non-mineralized water to dilute the mineralized water, reducing the probability that the mineral content of the final water output from the filter element assembly 1 is too high, thereby improving the safety and stability of the filter element assembly 1.

[0049] In one specific embodiment of this application, the main body of the device is provided with a first water outlet 21, which connects a first water outlet 113, a second water outlet 123, and a water outlet component. The water outlet component is used to dispense water to the outside for users to use; for example, the water outlet component can be a faucet.

[0050] In the structure provided in this specific embodiment, both the non-mineralized water flowing out through the first outlet 113 and the mineralized water flowing out through the second outlet 123 flow into the first water outlet path 21. The two types of water with different mineral contents can mix in the first water outlet path 21 and then flow to the water outlet component. This allows the user to obtain diluted mineralized water with a moderate mineral content when using the water outlet component, reducing the probability of the water outlet component having an excessively high mineral content and improving the safety and stability of the filter element assembly 1.

[0051] See Figure 4 , Figure 4 This is a schematic diagram of the water circuit structure of the mineral water purifier provided in this application. In a specific embodiment of this application, the main body of the device includes a first inlet valve 231, a second inlet valve 232, and a controller. The main body of the device has a first inlet water path 23a and a second inlet water path 23b, which are arranged in parallel. The first inlet valve 231 is connected to the first inlet water path 23a, which is connected to a first inlet 112. The second inlet valve 232 is connected to the second inlet water path 23b, which is connected to a second inlet 122. The controller is connected to the first inlet valve 231 and the second inlet valve 232.

[0052] The structure provided in this specific embodiment allows for effective control of the opening and closing of the first inlet valve 231 and the second inlet valve 232 using a controller. This controls the flow rate and velocity of water flowing through the mineralized filter media 111 via the first inlet water path 23a, as well as the flow rate and velocity of water flowing through the non-mineralized filter media 121 via the second inlet water path 23b. Consequently, the ratio of mineralized water to non-mineralized water mixed in the first outlet water path 21 can be controlled, thereby achieving regulation of the mineral content of the water discharged from the outlet component.

[0053] See Figure 5 , Figure 5 This is a schematic diagram of another water circuit structure for the mineral water purifier provided in this application. In a specific embodiment of this application, the main body of the device includes a first water outlet valve 211, a second water outlet valve 212, and a controller. The first water outlet circuit 21 includes a first branch circuit 21a, a second branch circuit 21b, and a confluence circuit 21c.

[0054] One end of the first branch 21a is connected to the first outlet valve 211, and the other end is connected to the confluence water path 21c. The end of the first outlet valve 211 away from the first branch 21a is connected to the first outlet 113. One end of the second branch 21b is connected to the second outlet valve 212, and the other end is connected to the confluence water path 21c. The end of the second outlet valve 212 away from the second branch 21b is connected to the second outlet 123. The end of the confluence water path 21c away from both the first branch 21a and the second branch 21b is connected to the water outlet component. The controller is connected to the first outlet valve 211 and the second outlet valve 212.

[0055] The structure provided in this specific embodiment allows the control to control the opening and closing of the first outlet valve 211 and the second outlet valve 212, thereby controlling the flow rate and velocity of the mineralized water flowing out through the first branch 21a and the non-mineralized water flowing out through the second branch 21b. This, in turn, controls the ratio of mineralized water to non-mineralized water flowing into the confluence water path 21c, thus achieving regulation of the mineral content of the water discharged from the outlet component.

[0056] See Figure 6 , Figure 6 This is another schematic diagram of the water circuit structure of the mineral water purifier provided in this application. In a specific embodiment of this application, the main body of the device further includes a water quality detection component 24, which is connected to a controller. At least one of the confluence water circuit 21c and the first branch circuit 21a is equipped with a water quality detection component 24.

[0057] Optionally, the water quality detection component 24 can also be located inside the first cavity 11.

[0058] In the structure provided in this specific embodiment, the water quality detection component 24 is set in the confluence water path 21c to directly characterize the water quality of the water output from the water outlet component. The water quality detection component 24 is set in the first branch 21a or the first cavity 11 to measure the water quality of the mineralized water output from the mineralized water path to a certain extent. The non-mineralized water required to adjust the mineralized water to a specified mineral content range can be calculated based on the water quality of the mineralized water.

[0059] Therefore, by setting up the water quality detection component 24, the water quality in the filter element component 1 can be effectively monitored. This allows the controller to adjust at least one of the valves, such as the first inlet valve 231, the second inlet valve 232, the first outlet valve 211, and the second outlet valve 212, based on the water quality feedback. This improves the accuracy of the mineral content control in the mineral water purifier, enabling it to output water that better meets user needs and enhancing its usability.

[0060] In one specific embodiment of this application, the water quality detection component 24 includes a TDS sensor.

[0061] In the structure provided in this embodiment, the TDS sensor is a device for measuring total dissolved solids (TDS) in water. It can continuously monitor the conductivity value of the analyte, and the mineral content in the analyte is calculated based on the conductivity value, thereby characterizing the mineral content of the water body.

[0062] In one specific embodiment of this application, the main body of the device includes a diversion valve 221 and a controller, and the main body of the device is also provided with a diversion water passage 22. One end of the diversion water passage 22 is connected to the first water inlet 112, and the other end is connected to the diversion valve 221. The diversion valve 221 is also connected to the second water outlet 123 and the first water outlet passage 21, and the controller is connected to the diversion valve 221.

[0063] In the structure provided in this specific embodiment, the non-mineralized water flowing out from the non-mineralized water path can selectively enter the first outlet water path 21 or the mineralized water path under the control of the diversion valve 221. The flow rate and velocity of the water entering the mineralized water path can be controlled, thereby controlling the ratio of mineralized water to non-mineralized water in the first outlet water path 21, and thus controlling the mineral content of the water finally output through the outlet component.

[0064] Alternatively, the diversion valve 221 can be replaced by two flow valves, one of which is connected to the diversion water passage 22 and the second outlet 123, and the other flow valve is connected to the second outlet 123 and the first outlet water passage 21.

[0065] Optionally, when the mineralizing filter media 111 is zinc mineralizing filter media 111 and the non-mineralizing filter media 121 is alkaline filter media, alkaline water will flow out from the non-mineralized water path. The alkaline water has a certain inhibitory effect on the dissolution of zinc element in zinc mineralizing filter media 111, thereby inhibiting the probability of zinc element exceeding the standard in mineralized water, and thus achieving the effect of controlling the zinc element content of the water body finally output through the water outlet component.
