Description

Technical Field

[0001] This utility model relates to the field of water purifier technology, specifically to a water dispenser. Background Technology

[0002] Mineralized filters are functional components in water dispensers, used to replenish purified water with beneficial minerals such as calcium, magnesium, potassium, and strontium. They can also optimize water quality characteristics. Through specific mineralizing materials, such as maifan stone, coral sand, and tourmaline, they can adjust the pH value of the water, improve taste, and enhance drinking water health. Some mineralized filters also have antibacterial and antioxidant functions, further improving the quality of purified water.

[0003] Currently, it is becoming increasingly common for water dispensers to have multiple mineralization filters, each containing different mineralizing materials, such as filter A for magnesium, filter B for calcium, and filter C for pH adjustment. Users can switch between these functions via valves, such as: baby / mother mode (low sodium, high calcium), tea brewing mode (weakly alkaline), and sports hydration mode (magnesium-rich).

[0004] If users consistently use only one function (such as selecting only the calcium supplementation path), other mineralizing filter cartridges will remain idle for an extended period. Consequently, water may stagnate in these unused cartridges. Stagnant water flow within unused mineralizing filter cartridges leads to mineral buildup, microbial growth on the surface of the cartridges and mineralizing materials, and ultimately, bacterial proliferation. Utility Model Content

[0005] To at least partially address the problems existing in the prior art, embodiments of this utility model provide a water dispenser. The water dispenser may include a main water inlet and a main water outlet, and may further include a water supply circuit, multiple mineralizing filter assemblies arranged in parallel, and multiple outlet valves. A booster pump may be installed on the water supply circuit, and the water inlet of the water supply circuit can be connected to the main water inlet. The water inlets of the multiple mineralizing filter assemblies are all connected to the water outlet of the water supply circuit. The water inlets of the multiple outlet valves are respectively connected to the water outlets of the multiple mineralizing filter assemblies, and the water outlets of the multiple outlet valves are connected to the main water outlet. Specifically, activating the booster pump increases the water pressure in the upstream pipeline of the mineralizing filter assemblies, thereby increasing the water pressure within each mineralizing filter assembly. When one or more outlet valves are opened, water flows from the outlets of one or more mineralizing filter assemblies connected to them, and the water pressure in the water dispenser decreases. Since the inlets of all mineralization filter cartridges are interconnected, the water pressure in the mineralization filter cartridge connected to the closed outlet valve can be released through the pipeline of the mineralization filter cartridge located on the part of the outlet valve that is open. Therefore, the water in the unused mineralization filter cartridges can maintain a certain flow, reducing the possibility of bacterial growth caused by the accumulation of minerals and the proliferation of microorganisms.

[0006] In some embodiments, a check valve and a high-pressure switch can be sequentially installed along the water flow direction in the water path between the inlets of multiple mineralization filter cartridges and the outlet of the water supply path. The high-pressure switch can be electrically connected to a booster pump, which operates when the high-pressure switch is closed. The high-pressure switch not only controls the operation of the booster pump but also allows for the accumulation of higher pressure in all mineralization filter cartridges after water intake ceases. Therefore, during the next water intake, this higher pressure can increase the fluidity of the water stored in the unused mineralization filter cartridges.

[0007] In some embodiments, the water dispenser may further include a filter, an inlet valve, an electric faucet, and a controller. The filter and inlet valve are connected in series with a booster pump in the water supply line, with the inlet valve located upstream of the filter and the filter downstream of the booster pump. The filter includes a raw water inlet, a clean water inlet, and a wastewater inlet. The raw water inlet of the filter is connected to the outlet of the booster pump, and the clean water inlet of the filter is connected to the inlets of multiple mineralization filter elements. The inlet of the electric faucet is connected to the main outlet. The controller is electrically connected to the inlet valve, the electric faucet, and the booster pump. The controller can be used to close the outlet valves in response to user operation of the electric faucet and to close the inlet valves and the booster pump after a preset time. After all outlet valves are closed, the booster pump continues to operate, accumulating pressure in the pipeline between the outlet of the booster pump and the inlets of all outlet valves, thereby accumulating higher pressure in all mineralization filter elements. After the booster pump is shut off, the higher pressure within the mineralization filter elements can be released through the wastewater inlet of the filter. This allows for greater water flow in unused mineralized filter cartridges, and ensures that the first stream of water flowing from the main outlet when the user draws water next time will not contain minerals from the mineralized filter cartridges connected to the closed outlet valve.

[0008] In some embodiments, the water dispenser may further include a pressure relief line, an electric faucet, and a controller. The inlet of the pressure relief line is connected to the outlet of the water supply line and / or the inlet of at least one of the multiple mineralization filter assemblies. A pressure relief valve is provided on the pressure relief line. The inlet of the electric faucet is connected to the main outlet. The controller is electrically connected to the electric faucet, the booster pump, and the pressure relief valve. The controller can also be used to close the outlet valves in response to user operation of the electric faucet, and after a preset time, close the booster pump and open the pressure relief valve. After all outlet valves are closed, the booster pump continues to operate for a preset time, accumulating pressure in the pipeline between the outlet of the booster pump and the inlets of all outlet valves, thereby accumulating higher pressure in all mineralization filter assemblies. After the booster pump is closed and the pressure relief valve is opened, the higher pressure within the mineralization filter assemblies can be released via the pressure relief line. This allows for greater water flow in unused mineralized filter cartridges, and ensures that the first stream of water flowing from the main outlet when the user draws water next time will not contain minerals from the mineralized filter cartridges connected to the closed outlet valve.

[0009] In some embodiments, each mineralizing filter assembly may include a filter cover and a mineralizing filter element. The filter cover has an inlet and an outlet for the corresponding mineralizing filter assembly. An outlet valve connected to the corresponding mineralizing filter assembly can be mounted on the filter cover. The mineralizing filter element is connected to the filter cover. The inlet of the mineralizing filter element is connected to the inlet of the corresponding mineralizing filter assembly, and the outlet of the mineralizing filter element is connected to the outlet of the corresponding mineralizing filter assembly. Mounting the outlet valve on the filter cover saves space occupied by the mineralizing filter assembly and the outlet valve, and facilitates the assembly of the water dispenser.

[0010] In some embodiments, the filter cartridge cover may include a cover body and a first tube body disposed on the cover body. The first tube body has a first inlet end and a first outlet end opposite to each other. The outlet of a water outlet valve mounted on the filter cartridge cover is connected to the middle of the first tube body. For any two adjacent mineralization filter cartridge assemblies, the first outlet end of one mineralization filter cartridge assembly is connected to the first inlet end of the other mineralization filter cartridge assembly via a first method. Thus, the outlets of multiple water outlet valves can be connected in series through the first tube body. Users can determine the connection method between the first tube bodies of adjacent mineralization filter cartridge assemblies as needed; for example, an integrated connection method can be used if leakage is a concern, while a quick-connect plug connection method can be used if easy replacement and maintenance of the mineralization filter cartridge assembly is required.

[0011] In some embodiments, the first approach may include integral connection and / or quick-connect plug connection. Using an integral connection reduces the number of interfaces and avoids the risk of leakage. Using a quick-connect plug connection facilitates installation, disassembly, and maintenance.

[0012] In some embodiments, multiple mineralization filter cartridges are arranged in a direction parallel to the first tube. This saves space occupied by multiple mineralization filter cartridges and facilitates connecting multiple mineralization filter cartridges together.

[0013] In some embodiments, the filter cartridge cover may include a cover body and a second tube disposed on the cover body. The second tube has opposing second inlet and second outlet ends. The inlet of the mineralization filter element on the filter cartridge cover is connected to the middle of the second tube. For any two adjacent mineralization filter elements, the second outlet end of one mineralization filter element is connected to the second inlet end of the other mineralization filter element via a second method. Users can determine the connection method between the second tubes of adjacent mineralization filter elements as needed; for example, an integrated connection method can be used if leakage is a concern, while a quick-connect plug connection method can be used if easy replacement and maintenance of the mineralization filter elements is required.

[0014] In some embodiments, the second approach may include integral connection and / or quick-connect plug connection. Integral connection reduces the number of interfaces and avoids the risk of leakage. Quick-connect plug connection facilitates installation, disassembly, and maintenance.

[0015] In some embodiments, multiple mineralization filter cartridges are arranged in a direction parallel to the second tube. This saves space occupied by multiple mineralization filter cartridges and facilitates connecting multiple mineralization filter cartridges together.

[0016] In some embodiments, the filter cover of each mineralization filter assembly may be an integral piece. The filter cover of each mineralization filter is integrated with the corresponding water outlet valve, which facilitates the assembly of the water dispenser.

Detailed Implementation

[0029] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0030] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0031] According to one aspect of this application, a water dispenser is provided. The principles of this application will be described below with reference to the accompanying drawings.

[0032] See also Figure 1The water dispenser may include a main inlet 101 and a main outlet 102. The main inlet 101 can be used to receive raw water. The main outlet 102 can output purified and / or mineralized water. The water dispenser may also include a water supply circuit (see the dashed box in the figure), multiple mineralization filter assemblies 300 arranged in parallel, and multiple outlet valves 400. Hereinafter, "multiple" refers to two or more. The inlet of the water supply circuit is connected to the main inlet 101. A booster pump 110 may be installed on the water supply circuit. The booster pump 110 may be any of, but is not limited to, a diaphragm pump, a centrifugal pump, or a plunger pump. The booster pump 110 can be used to increase the water pressure in the water dispenser. The inlets 301 of the multiple mineralization filter assemblies 300 are all connected to the outlets of the water supply circuit. The mineralizing filter element 300 can be used to add minerals to purified water and / or adjust pH levels to provide users with water that is beneficial to health and / or has a better taste. Optionally, the mineralizing filter element 300 may include, but is not limited to, providing one or more of the following minerals: potassium, sodium, phosphorus, calcium, magnesium, strontium, zinc, iron, selenium, copper, iodine, and metasilicic acid. Optionally, the mineralizing filter element 300 may include one or more of the following materials: maifanite, coral sand, tourmaline, zeolite, and montmorillonite, for adjusting the pH value of the purified water. Multiple mineralizing filter elements 300 are connected in parallel to the outlet of the water supply circuit. Exemplarily, at least a portion of the multiple mineralizing filter elements 300 may contain different active ingredients than the other mineralizing filter elements 300 to achieve the purpose of adding different minerals and / or improving taste. The inlets of multiple outlet valves 400 are connected to the outlets 302 of multiple mineralization filter elements 300, and the outlets of the multiple outlet valves 400 are connected to the main outlet 102. The outlet valves 400 can be any combination of solenoid valves, electric valves, pneumatic valves, and hydraulic valves, as long as they can perform their function. Thus, the multiple outlet valves 400 are connected in series downstream of the multiple mineralization filter elements 300, respectively, to control whether the water output through the main outlet 102 passes through the corresponding mineralization filter element 300.

[0033] For example, such as Figure 1As shown, because the inlet of the outlet valve 400 is connected to the outlet 302 of the mineralizing filter assembly 300, the flow of water at the inlet 301 of the mineralizing filter assembly 300 is not affected by the outlet valve 400. Even if the outlet valve 400 connected to the mineralizing filter assembly 300 is closed, the water stored in the mineralizing filter assembly 300 can still flow to a certain extent due to changes in water pressure in the upstream pipeline. Specifically, turning on the booster pump 110 can increase the water pressure in the upstream pipeline of the mineralizing filter assembly 300. Under this condition, the water pressure in each mineralizing filter assembly 300 can increase. When one or more outlet valves 400 are opened, water flows out of the outlet 302 of one or more mineralizing filter assemblies 300 connected to them, and the water pressure in the water dispenser decreases. Since the inlets 301 of all mineralization filter elements 300 are interconnected, the water pressure in the mineralization filter element 300 connected to the closed outlet valve 400 can be released through the pipeline of the mineralization filter element 300 where the outlet valve 400 is open. Therefore, the water in the unused mineralization filter element 300 can maintain a certain flow, reducing the possibility of bacterial growth caused by the accumulation of minerals and the proliferation of microorganisms.

[0034] See also Figure 2In some embodiments, a check valve 160 and a high-pressure switch 150 can be sequentially installed along the water flow direction in the water path between the inlet 301 of multiple mineralization filter elements 300 and the outlet of the water supply path. The high-pressure switch 150 is electrically connected to the booster pump 110, which operates when the high-pressure switch 150 is closed. When any one or more outlet valves 400 are opened, water flows from the outlet 302 of the corresponding one or more mineralization filter elements 300. The water pressure in the mineralization filter elements 300 connected to the closed outlet valve 400 flows from the mineralization filter elements 300 connected to the open outlet valve 400 to the main outlet 102 of the water dispenser, causing a certain flow of water in the mineralization filter elements 300 connected to the closed outlet valve 400. At the same time, the water pressure in the pipeline where the high-pressure switch 150 is located decreases, the high-pressure switch 150 closes, the booster pump 110 starts working, and the water dispenser starts producing water. When the user stops drawing water and closes all outlet valves 400, the booster pump 110 continues to operate, thereby accumulating pressure in the pipeline between the outlet of the booster pump 110 and the inlets of all outlet valves 400. When the pressure reaches the level at which the high-pressure switch 150 is disconnected, the high-pressure switch 150 disconnects, and the booster pump 110 stops operating, thus allowing higher pressure to accumulate in all mineralization filter cartridges 300. When one or more outlet valves 400 are opened again, the pressure accumulated in all mineralization filter cartridges 300 can be released through the opened outlet valves 400 and the main outlet 102, allowing some flow of water in the unused mineralization filter cartridges 300. Therefore, the high-pressure switch 150 not only controls the operation of the booster pump 110 but also allows higher pressure to accumulate in all mineralization filter cartridges 300 after water drawing stops. Thus, during the next water drawing, this higher pressure allows for greater flow of water in the unused mineralization filter cartridges 300.

[0035] In the above embodiment, the pressure in the mineralization filter element assembly 300 connected to the closed water outlet valve 400 is released through the main water outlet 102. Therefore, each time water is taken out, the first stream of water flowing out of the main water outlet 102 may contain minerals from the mineralization filter element assembly 300 connected to the closed water outlet valve 400. Thus, the user can choose to pour out the first stream of water and then collect the purified water flowing out of the main water outlet 102.

[0036] See also Figure 3In some embodiments, the water dispenser may include a filtration device 120. The filtration device 120 is connected in series with a booster pump 110 in the water supply line, and is located downstream of the booster pump 110. The filtration device 120 includes a raw water inlet, a purified water inlet, and a wastewater inlet. The raw water inlet of the filtration device 120 is connected to the outlet of the booster pump 110, and the purified water inlet of the filtration device 120 is connected to the inlets 301 of multiple mineralization filter cartridges 300. The filtration device 120 may include, but is not limited to, one or more of reverse osmosis filter cartridges, ultrafiltration filter cartridges, and nanofiltration filter cartridges. The filtration device 120 can be used to remove minute impurities from the water. The wastewater inlet can be connected to a wastewater solenoid valve 140. The outlet of the wastewater solenoid valve 140 can be connected to the water dispenser's outlet 103, thereby discharging the wastewater generated during the water purification process of the filtration device 120 to the outside. When the wastewater solenoid valve 140 is closed, it allows wastewater to flow through at a certain flow rate, thereby maintaining the pressure of the filter device 120 during operation. When the wastewater solenoid valve 140 is open, it allows water to flow through without flow restriction, thereby flushing the filter device 120.

[0037] Optionally, to improve the service life of the booster pump 110 and / or the filter device 120, a pre-filter 130 can be installed upstream of the booster pump 110. The pre-filter 130 can perform preliminary filtration of the raw water, preventing large particles such as silt and rust from entering the filter device 120 and extending its service life.

[0038] The water dispenser may also include an inlet valve 170, an electric faucet 180, and a controller. The inlet valve 170 and booster pump 110 are connected in series in the water supply line, and the inlet valve 170 can be located upstream of the filter device 120. For example, it can be located in the pipeline between the pre-filter 130 and the booster pump 110. The inlet valve 170 can be any combination of one or more of the following: solenoid valve, electric valve, pneumatic valve, and hydraulic valve, as long as it can achieve its function. The solenoid valve can include ordinary solenoid valves and inlet solenoid valves. Ordinary solenoid valves only have an on / off function. Inlet solenoid valves are widely used in the water purification field; in addition to their on / off function, they also have directional properties. When energized, the inlet solenoid valve can conduct in both directions; when de-energized, it acts as a reverse-flow check valve. It can work in conjunction with other forward-flowing check valves in the water dispenser to cut off the water flow. In reverse osmosis water dispensers, an inlet solenoid valve is typically installed upstream of the booster pump 110 to cut off the water flow and prevent continuous wastewater flow. Using an inlet solenoid valve reduces the number of components in the water dispenser, facilitating standardization, reducing costs, and decreasing the probability of assembly errors. The inlet valve 170 can be used to disconnect the water flow when the booster pump 110 stops working, preventing raw water from flowing out of the wastewater outlet of the filter device 120. The inlet of the electric faucet 180 is connected to the main outlet 102 and can be used to receive user input. The controller is electrically connected to the inlet valve 170, the electric faucet 180, and the booster pump 110. The controller can close the already opened outlet valve 400 in response to user input to the electric faucet 180, and close the inlet valve 170 and the booster pump 110 after a preset time. The preset time can be between 1 second and 3 seconds, or slightly less than 1 second, or slightly more than 3 seconds. After all outlet valves 400 are closed, the booster pump 110 continues to operate, accumulating pressure in the pipeline between the outlet of the booster pump 110 and the inlets of all outlet valves 400, thereby accumulating higher pressure in all mineralization filter assemblies 300. After the booster pump 110 is closed, the higher pressure in the mineralization filter assemblies 300 can be released through the wastewater outlet of the filter device 120. This allows for higher fluidity of the water stored in the unused mineralization filter assemblies 300, and ensures that the first stream of water flowing from the main outlet 102 when the user draws water next time will not contain minerals from the mineralization filter assemblies 300 connected to the closed outlet valves 400.

[0039] See also Figure 4In some embodiments, the water dispenser may further include a pressure relief pipe 200, an electric faucet 180, and a controller. The inlet of the pressure relief pipe 200 is connected to the outlet of the water supply circuit and / or the inlet of at least one of the multiple mineralization filter assemblies 300. A pressure relief valve 210 is provided on the pressure relief pipe 200. The pressure relief valve 210 may be any combination of one or more of a solenoid valve, electric valve, pneumatic valve, and hydraulic valve, as long as it can perform its function. The inlet of the electric faucet 180 is connected to the main outlet 102 and can be used to receive user operations. The controller is electrically connected to the electric faucet 180, the booster pump 110, and the pressure relief valve 210. The controller can be used to close the outlet valve 400 in response to user operation of the electric faucet 180, close the booster pump 110 after a preset time, and open the pressure relief valve 210. The preset time may be within 1 second to 3 seconds, or slightly less than 1 second, or slightly greater than 3 seconds. After all outlet valves 400 are closed, the booster pump 110 continues to operate for a preset time, accumulating pressure in the pipeline between the outlet of the booster pump 110 and the inlets of all outlet valves 400, thereby accumulating higher pressure in all mineralization filter assemblies 300. After the booster pump 110 is closed and the pressure relief valve 210 is opened, the higher pressure in the mineralization filter assembly 300 can be released through the pressure relief pipeline 200. This allows for higher fluidity of the water stored in the unused mineralization filter assembly 300, and the first stream of water flowing from the main outlet 102 when the user draws water next time will not contain minerals from the mineralization filter assembly 300 connected to the closed outlet valves 400. For example, the pressure relief valve 210 can be opened simultaneously with the booster pump 110 being closed; or the booster pump 110 can be closed first and then the pressure relief valve 210 opened; or the pressure relief valve 210 can be opened first and then the booster pump 110 closed.

[0040] exist Figure 3 and Figure 4 In the illustrated embodiment, the booster pump 110 and the outlet valve 400 can also be opened by the electric faucet 180 and the controller.

[0041] See also Figure 5 and Figure 7In some embodiments, each mineralizing filter element assembly 300 may include a filter element cover 310 and a mineralizing filter element 320. The filter element cover 310 may be provided with a corresponding inlet 301 and outlet 302 for the mineralizing filter element assembly 300. An outlet valve 400 connected to the corresponding mineralizing filter element assembly 300 may be mounted on the filter element cover 310. Exemplarily, the filter element cover 310 may be provided with a mounting portion 314, and the outlet valve 400 may be fixedly mounted on the filter element cover 310 by the mounting portion 314. The mineralizing filter element 320 may be connected to the filter element cover 310. Exemplarily, the mineralizing filter element 320 may be detachably connected to the filter element cover 310 by any suitable means such as twisting, snapping, or fastening. With the mineralizing filter element 320 connected to the filter element cover 310, the inlet 321 of the mineralizing filter element 320 is connected to the inlet 301 of the corresponding mineralizing filter element assembly 300, and the outlet 322 of the mineralizing filter element 320 is connected to the outlet 302 of the corresponding mineralizing filter element assembly 300. Installing the outlet valve 400 on the filter element cover 310 can save space occupied by the mineralizing filter element assembly 300 and the outlet valve 400, and facilitates the assembly of the water dispenser.

[0042] See also Figure 5 and Figure 7 In some embodiments, water flows from the inlet 301 of the mineralizing filter assembly 300 through the inlet 321 of the mineralizing filter 320 into the mineralizing filter 320, then from the outlet 322 of the mineralizing filter 320 through the outlet 302 of the mineralizing filter assembly 300 into the inlet 401 of the outlet valve 400, and finally flows out from the outlet 402 of the outlet valve 400.

[0043] See also Figure 5 , Figure 6 and Figure 7 In some embodiments, the filter cover 310 may include a cover body 311 and a first tube body 312 disposed on the cover body 311. The first tube body 312 may have a first inlet end 312a and a first outlet end 312b opposite to each other. The outlet 402 of the water outlet valve 400 installed on the filter cover 310 may be connected to the middle portion 312c of the first tube body 312. For any two adjacent mineralization filter cartridges 300, the first outlet end 312b of one mineralization filter cartridge 300 may be connected to the first inlet end 312a of the other mineralization filter cartridge 300 through a first method. Thus, the outlets 402 of multiple water outlet valves 400 can be connected in series through the first tube body 312. The first method may include integral connection and / or quick-connect plug connection. Optionally, the first method may also include flange connection, threaded connection, etc. For n mineralization filter cartridges 300, n-1 groups of adjacent mineralization filter cartridges 300 can be formed, where n≥2 and n is an integer. Figure 6In the illustrated embodiment, there are four mineralization filter cartridge assemblies 300, and there can be three adjacent sets of mineralization filter cartridge assemblies 300. Figure 6 In the illustrated embodiment, the first tubes 312 of the three adjacent mineralization filter element assemblies 300 are all integrally connected. This integral connection reduces the number of interfaces and avoids the risk of leakage. In embodiments not shown, among multiple adjacent mineralization filter element assemblies, some groups may have their first tubes integrally connected, while others may have their first tubes connected via quick-connect plugs; or all groups of adjacent filter element assemblies may have their first tubes connected via quick-connect plugs. Using quick-connect plugs facilitates installation, disassembly, and maintenance. In practical use, users can decide the connection method between the first tubes of adjacent mineralization filter element assemblies based on their needs. For example, an integral connection method is used if leakage is a concern, while a quick-connect plug method is used if easy replacement and maintenance of the mineralization filter element assemblies is required.

[0044] In the illustrated embodiment, the first tube 312 is straight. Exemplarily, multiple mineralization filter assemblies 300 can be arranged in a direction parallel to the first tube 312, thus saving space occupied by the multiple mineralization filter assemblies 300 and facilitating their connection. In other embodiments not shown, the first tube may be curved.

[0045] See also Figure 5 , Figure 6 and Figure 7 In some embodiments, the filter cartridge cover 310 may include a cover body 311 and a second tube body 313 disposed on the cover body 311. The second tube body 313 may have opposing second inlet ends 313a and second outlet ends 313b. The inlet 301 of the mineralization filter cartridge assembly 300 on the filter cartridge cover 310 may be connected to the middle of the second tube body 313. For any two adjacent mineralization filter cartridge assemblies 300, the second outlet end 313b of one mineralization filter cartridge assembly 300 may be connected to the second inlet end 313a of the other mineralization filter cartridge assembly 300 through a second method. The second method may include integral connection and / or quick-connect plug connection. Optionally, the second method may also include flange connection, threaded connection, etc. For n mineralization filter cartridge assemblies 300, n-1 groups of adjacent mineralization filter cartridge assemblies 300 may be formed, where n≥2 and n is an integer. Figure 6 In the illustrated embodiment, there are four mineralization filter cartridge assemblies 300, and there can be three adjacent sets of mineralization filter cartridge assemblies 300. Figure 6In the illustrated embodiment, the second tubes 313 of the three adjacent mineralization filter element assemblies 300 are all integrally connected. This integral connection reduces the number of interfaces and avoids the risk of leakage. In embodiments not shown, among multiple adjacent mineralization filter element assemblies, some groups may have their second tubes integrally connected, while others may be connected via quick-connect plugs; or the second tubes of multiple adjacent filter element assemblies may all be connected via quick-connect plugs. Using quick-connect plugs facilitates installation, disassembly, and maintenance. In practical use, users can decide the connection method between the second tubes of adjacent mineralization filter element assemblies based on their needs. For example, an integral connection method is used if leakage is a concern, while a quick-connect plug method is used if easy replacement and maintenance of the mineralization filter element assemblies is required.

[0046] In some embodiments, the cover 311 and the first tube 312 may be integral to facilitate manufacturing and reduce the risk of leakage. In some embodiments, the cover 311 and the second tube 313 may be integral to facilitate manufacturing and reduce the risk of leakage. In some embodiments, the cover 311, the first tube 312, and the second tube 313 may be integral to facilitate manufacturing and reduce the risk of leakage. In some embodiments, the filter cover 310 of each mineralization filter element assembly 300 may be integral. This facilitates manufacturing and reduces the risk of leakage.

[0047] In the illustrated embodiment, the second tube 313 is straight. Exemplarily, multiple mineralization filter assemblies 300 can be arranged in a direction parallel to the second tube 313, thus saving space occupied by the multiple mineralization filter assemblies 300 and facilitating their integration. In other embodiments not shown, the second tube may be curved.

[0048] In some embodiments, such as Figure 6As shown, a first tube 312 and a second tube 313 may be provided on the cover 311. The first inlet end 312a and the second outlet end 313b of one of two adjacent mineralization filter element assemblies 300 can be connected to the first outlet end 312b and the second inlet end 313a of the other mineralization filter element assembly 300, respectively. The connection method may include integral connection and / or quick-connect plug connection. In some embodiments, each group of adjacent mineralization filter element assemblies 300 can be integrally connected, thus requiring only four interfaces for multiple mineralization filter element assemblies 300, avoiding the risk of leakage caused by too many interfaces. In other embodiments, each group of adjacent mineralization filter element assemblies 300 can be connected using quick-connect plugs, allowing each mineralization filter element assembly 300 to be quickly installed and removed, facilitating user replacement and maintenance of the mineralization filter element assemblies 300 as needed. In practical use, users can decide the connection method of adjacent mineralization filter elements according to their needs. If they are worried about water leakage, they can use the integrated connection method. If they need to easily replace and maintain the mineralization filter elements, they can use the quick-connect plug connection method.

[0049] In some embodiments, the filter cover 310 of one or more mineralizing filter cartridge assemblies 300 may be integral. Furthermore, the first tube 312 and the second tube 313 may also be connected to the filter cover 310 of other mineralizing filter cartridge assemblies 300 via quick-connect fittings, thereby allowing the number of filter covers 310 to be expanded as needed to match the desired number of mineralizing filter cartridges 320. The filter cover 310 of each mineralizing filter cartridge 320 is integrated with the corresponding water outlet valve 400, thus facilitating the assembly of the water dispenser.
