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 increased productivity, people's demands for quality of life and convenience are also rising. Alkaline water, with a pH value greater than 7, can replenish fluids, improve microcirculation, and promote metabolism when consumed in moderation. Furthermore, alkaline water can help alleviate water and electrolyte imbalances; for example, it can aid in rehydration after significant vomiting. In addition, alkaline water can help neutralize excess stomach acid, protect the gastric mucosa, and reduce the likelihood of peptic ulcers. Therefore, mineralized water is widely favored as drinking water. There is also a certain demand for alkaline water during production and experimental processes.

[0003] Currently, there are two common methods for preparing alkaline water. The first method involves artificially mixing alkaline substances with water to create alkaline water with a suitable pH value. However, this method is cumbersome, requires a certain level of chemical knowledge, and is relatively inefficient. The second method involves adding a substrate containing alkaline substances to a container filled with water—such as a water dispenser or water purifier. The alkaline substances in the substrate dissolve into the water in the container, turning it into alkaline water. However, alkaline water prepared using this method is difficult to control effectively in terms of pH value. If the pH value is too high, it can have negative effects on the user.

[0030] With increased productivity, people's demands for quality of life and convenience are also rising. Alkaline water, with a pH value greater than 7, can replenish fluids, improve microcirculation, and promote metabolism when consumed in moderation. Furthermore, alkaline water can help alleviate water and electrolyte imbalances; for example, it can aid in rehydration after significant vomiting. In addition, alkaline water can help neutralize excess stomach acid, protect the gastric mucosa, and reduce the likelihood of peptic ulcers. Therefore, mineralized water is widely favored as drinking water. There is also a certain demand for alkaline water during production and experimental processes.

[0031] Currently, there are two common methods for preparing alkaline water. The first method involves artificially mixing alkaline substances with water to create alkaline water with a suitable pH value. However, this method is cumbersome, requires a certain level of chemical knowledge, and is relatively inefficient. The second method involves adding a substrate containing alkaline substances to a container filled with water—such as a water dispenser or water purifier.

However, alkaline water prepared using this method is difficult to control effectively in terms of pH value. If the pH value is too high, 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 to 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 alkaline filter media 111 and adsorption / purification filter media 121.

[0034] The filter element assembly 1 may have 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. Alkaline filter media 111 is disposed in the first chamber 11, and adsorption-purification filter media 121 is disposed in the second chamber 12. The filter element assembly 1 is provided with an alkaline water path through which the alkaline filter media 111 flows and an adsorption-purification water path through which the adsorption-purification filter media 121 flows. The alkaline water path and the adsorption-purification water path are arranged in parallel, or the alkaline water path can be connected to the adsorption-purification water path through a branch water path 22.

[0035] In the structure provided in this specific embodiment, the alkaline water path and the adsorption purification water path are arranged in parallel, or the alkaline water path is connected to the adsorption purification water path through the diversion water path 22. This enables the mixing of alkaline water flowing through the alkaline filter material 111 and purified water flowing through the adsorption purification filter material 121. The purified water is used to dilute the alkaline water, reducing the probability that the pH value of the final effluent from the filter element assembly 1 is too high, thereby improving the safety and stability of the filter element assembly 1.

[0036] In one specific embodiment of this application, the alkaline filter material 111 and the adsorption and purification filter material 121 can be respectively disposed in the first cavity 11 and the second cavity 12 along the axial direction of the filter element assembly 1. The filter element assembly 1 also includes a housing 13 and an isolation component 14. The second cavity 12 is disposed within the housing 13, the isolation component 14 is disposed within the second cavity 12, and the first cavity 11 is disposed within the isolation component 14. The first water inlet 112, the second water inlet 122, the first water outlet 113, and the second water outlet 123 are disposed within the housing 13.

[0037] The alkaline water circuit may include a first internal water circuit 15 and a second internal water circuit 16, and the adsorption and purification water circuit may include a third internal water circuit 17 and a fourth internal water circuit 18. One end of the first internal water circuit 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 circuit 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 circuit 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 circuit 18 is connected to the first outlet 113, and the other end is connected to the first cavity 11.

[0038] The structure provided in this specific embodiment uses the isolation component 14 to isolate the first chamber 11 and the second chamber 12, thereby realizing the parallel setting of the alkaline water path and the adsorption purification water path. In this way, the purified water flowing out of the adsorption purification water path can be used to dilute the alkaline water flowing out of the alkaline water path, reducing the probability that the pH value of the final water output from the filter element assembly 1 is too high, and improving the safety and stability of the filter element assembly 1.

[0039] In one specific embodiment of this application, the isolation component 14 may specifically include an annular isolation body 143 and a central tube 144. The central tube 144 is arranged along the axial direction of the filter element assembly 1, and the annular isolation body 143 is sleeved on the outer periphery of the lower end of the central tube 144. The adsorption and purification filter material 121 is sleeved on the outer periphery of the upper end of the central tube 144, the second inner water channel 16 is disposed inside the central tube 144, and the adsorption and purification filter material 121 is disposed between the second inner water channel 16 and the second water inlet 122.

[0040] With the structure provided in this specific embodiment, the annular isolation body 143 and the adsorption and purification filter material 121 are respectively sleeved on 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 water outlet component is connected to the second cavity 12 by the central tube 144, so that the fluid flowing out of the second water outlet 123 can be filtered by the adsorption and purification filter material 121, which can improve the stability of the filter element assembly 1.

[0041] 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.

[0042] like Figure 2 As shown, the central tube 144 may include a horizontal baffle 144a, with a first cavity 11 and a second cavity 12 respectively disposed on both sides of the horizontal baffle 144a. The adsorption and purification filter material 121 has a central channel 121a, and the upper end of the central tube 144 is fitted into this central channel 121a. The housing 13 may include an end cap, which is placed on one end of the adsorption and purification filter material 121 to block one end of the central channel 121a. The end of the adsorption and purification filter element away from the end cap abuts against the horizontal baffle 144a. The alkaline filter material 111 abuts against the horizontal baffle and the annular isolation body 143 along the circumference of the central tube 144.

[0043] 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.

[0044] 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.

[0045] This application also provides a mineral water purifier, including a main body and a filter element assembly 1 as described in any of the above embodiments. The main body is used to connect with the filter element assembly 1.

[0046] In the structure provided in this specific embodiment, the alkaline water path and the adsorption purification water path are arranged in parallel in the filter element assembly 1, or the alkaline water path is connected to the adsorption purification water path through the diversion water path 22. This enables the mixing of alkaline water flowing through the alkaline filter material 111 and purified water flowing through the adsorption purification filter material 121. The purified water is used to dilute the alkaline water, reducing the probability that the pH value of the final effluent from the filter element assembly 1 is too high, thereby improving the safety and stability of the filter element assembly 1.

[0047] 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.

[0048] In the structure provided in this specific embodiment, the purified water flowing out through the first outlet 113 and the alkaline water flowing out through the second outlet 123 both flow into the first water outlet path 21, so that the two types of water with different alkalinity are mixed in the first water outlet path 21 and then flow to the water outlet component. This allows the user to obtain diluted alkaline water when using the water outlet component, reducing the probability that the pH value of the water from the water outlet component is too high, and improving the safety and stability of the filter element assembly 1.

[0049] 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 may include 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.

[0050] The structure provided in this specific embodiment allows the controller to effectively control the opening and closing of the first inlet valve 231 and the second inlet valve 232, thereby controlling the flow rate and velocity of the water flowing through the alkaline filter material 111 via the first inlet water path 23a and the water flowing through the adsorption and purification filter material 121 via the second inlet water path 23b. This, in turn, allows the controller to control the ratio of alkaline water to purified water mixed in the first outlet water path 21, thereby achieving the regulation of the pH value of the outlet water from the outlet component.

[0051] 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 may include 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 converging water circuit 21c.

[0052] The first branch 21a is connected at one end to the first outlet valve 211 and at the other end to the confluence water path 21c. The end of the first outlet valve 211 furthest from the first branch 21a is connected to the first outlet 113. The second branch 21b is connected at one end to the second outlet valve 212 and at the other end to the confluence water path 21c. The end of the second outlet valve 212 furthest from the second branch 21b is connected to the second outlet 123. The end of the confluence water path 21c furthest from both the first branch 21a and the second branch 21b is connected to the outlet component. The controller is connected to the first outlet valve 211 and the second outlet valve 212.

[0053] 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 alkaline water flowing out through the first branch 21a and the purified water flowing out through the second branch 21b. This, in turn, controls the ratio of alkaline water to purified water flowing into the confluence water path 21c, thus achieving regulation of the pH value of the water outlet component.

[0054] In one specific embodiment of this application, the main body of the device may further include a water quality detection component 24, which is connected to a controller. At least one of the confluence water path 21c and the first branch path 21a is equipped with a water quality detection component 24.

[0055] Optionally, the water quality detection component 24 can also be located inside the first cavity 11.

[0056] In the structure provided in this specific embodiment, the water quality detection component 24 installed in the confluence water path 21c can directly characterize the water quality of the water output from the water outlet component. The water quality detection component 24 installed in the first branch path 21a or the first cavity 11 can, to a certain extent, measure the water quality of the alkaline water output from the alkaline water path. Based on the water quality of the alkaline water, the required purified water to adjust the alkaline water to a specified pH range can be calculated. Therefore, by installing the water quality detection component 24, the water quality in the filter element assembly 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 water purifier in regulating the alkalinity of the output water, enabling the mineral water purifier to output water that better meets the user's needs and enhancing the usability of the mineral water purifier.

[0057] In one specific embodiment of this application, the water quality detection component 24 may include at least one of a pH sensor and a TDS sensor. In the structure provided in this embodiment, the pH sensor is used to detect the hydrogen ion concentration in the analyte and can convert it into a corresponding usable output signal, thereby characterizing the pH value of the water body. The TDS sensor is a device used to measure total dissolved solids (TDS) in water, capable of continuously monitoring the conductivity value of the analyte. The pH value of the analyte can be calculated based on the conductivity value, thereby characterizing the pH value of the water body.

[0058] See Figure 6 , Figure 6This 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 may include a diversion valve 221 and a controller, and the main body of the device is also provided with a diversion water circuit 22. One end of the diversion water circuit 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 circuit 21, and the controller is connected to the diversion valve 221.

[0059] In the structure provided in this specific embodiment, the purified water flowing out from the adsorption purification water path can selectively enter the first outlet water path 21 or the alkaline water path under the control of the diversion valve 221. The flow rate and velocity of the water entering the alkaline water path can be controlled, thereby controlling the ratio of alkaline water to purified water in the first outlet water path 21, and thus controlling the pH value of the water finally output through the outlet component.

[0060] 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.
