Description

Technical Field

[0001] This application relates to the field of diverter technology, and in particular to a diverter and a water purification system. Background Technology

[0002] In related technologies, since existing pressure reducing valves and diverter valves are independently configured components in the water purification system, both existing pressure reducing valves and diverter valves have housings and connecting parts. This makes the layout of the water purification system less compact and makes the installation of the system more complex, increasing the difficulty of assembly and the risk of leakage. Summary of the Invention

[0003] This application provides a diverter and a water purification system, which can solve the problems of complex layout, increased assembly difficulty, and leakage associated with existing water purification systems.

[0004] In a first aspect, embodiments of this application provide a current splitter, the current splitter comprising:

[0005] The valve housing includes an upper valve body shell and a lower valve body shell connected to each other. The upper valve body shell and the lower valve body shell form an inlet chamber, a return chamber and an outlet chamber. The outlet chamber can communicate with the inlet chamber through the return chamber. The upper valve body shell is an integrally formed component, and / or the lower valve body shell is an integrally formed component.

[0006] A pressure regulating component is disposed within the water inlet chamber;

[0007] A diversion component is disposed within the water outlet chamber;

[0008] A one-way flow guide is provided in the return chamber to prevent the pressure-stabilized water after it has been stabilized in the inlet chamber from flowing back to the outlet chamber, and to combine the excess water flowing back from the outlet chamber toward the return chamber with the pressure-stabilized water before outputting it to the water purifier.

[0019] When the water pressure on the inlet side is less than or equal to the water pressure on the outlet side, the sealing head of the movable opening and closing part abuts against and seals the inlet.

[0020] When the water pressure on the inlet side is greater than the water pressure on the outlet side, the sealing head of the movable opening and closing part moves away from the inlet and the elastic reset part deforms, so that the inlet and the outlet are connected.

[0021] In one embodiment, the fixing shell includes:

[0026] In one embodiment, the diversion component includes: a flexible check valve with a flow regulating port, wherein the flexible check valve can control the opening and closing size of the flow regulating port according to the pressure difference.

[0031] The diaphragm top cover has a top cover through hole; and,

[0032] The diaphragm base is provided with a base through hole;

[0033] The diversion balancing membrane is sandwiched between the membrane top cover and the membrane base. The through hole of the top cover and the through hole of the base are both connected to the through hole of the membrane. The through hole of the top cover, the through hole of the base, and the through hole of the membrane form the flow hole. One end of the balancing spring abuts against the inner wall of the water outlet chamber, and the other end of the balancing spring abuts against the membrane top cover.

[0034] In one embodiment, the pressure regulating component divides the water inlet chamber into an air chamber and a liquid chamber. The pressure regulating component is provided with a water injection guide hole and a pressure regulating outlet. Both the water injection guide hole and the pressure regulating outlet are connected to the liquid chamber.

[0036] In one embodiment, the voltage regulating component includes:

[0038] A flexible pressure regulating element is detachably connected to the valve core assembly, and the pressure regulating element is connected between the upper shell of the valve body and the lower shell of the valve body.

[0039] Secondly, embodiments of this application provide a water purification system, which includes:

[0040] The aforementioned splitter;

[0041] Water purifier;

[0042] A tankless water dispenser is used to heat or cool water that has been purified by the water purifier.

[0043] The faucet, the tankless water dispenser, and the water purifier are all connected to the distributor.

[0044] Based on the above embodiments, the diverter proposed in this application includes a valve housing, a pressure regulating component, and a diverting component. The valve housing includes an upper valve body shell and a lower valve body shell connected to each other. The upper and lower valve body shells constitute an inlet chamber, a return chamber, and an outlet chamber. The outlet chamber can communicate with the inlet chamber through the return chamber. The upper valve body shell is an integrally formed component, and / or the lower valve body shell is an integrally formed component. The pressure regulating component is disposed in the inlet chamber, the diverting component is disposed in the outlet chamber, and the unidirectional flow guide is disposed in the return chamber to prevent the pressure-stabilized water flowing through the inlet chamber from flowing back to the outlet chamber, and to combine the excess water flowing back from the outlet chamber to the return chamber with the pressure-stabilized water before outputting it to the water purifier.

[0045] Compared to related technologies, the technical solution of this application integrates pressure reducing and diversion functions by setting an inlet and outlet chamber in the valve body. This solves the problem of independent configuration of pressure reducing valves and diversion valves in existing drinking water purification systems. Furthermore, the unidirectional flow guide component is installed in the return chamber connecting the outlet and inlet chambers, simplifying the piping layout of the drinking water purification system and making the overall assembly more compact, significantly reducing the space occupied and lowering the complexity, installation difficulty, leakage risk, and maintenance and replacement costs of the system. In addition, when the diversion module suddenly shuts down, the pressure reducing module suddenly opens, or the external water supply pipeline pressure instantly increases, the unidirectional flow guide component can prevent such high-pressure waves from impacting the unidirectional flow guide component in the opposite direction, thus extending the service life of the diverter.

[0082] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0083] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0084] Where the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0085] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, in the description of this application, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0086] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0087] This application proposes a drinking water purification system, comprising a water purifier, a tankless water dispenser, and a faucet. The water purifier performs deep filtration and purification on the water supplied by the water supply pipeline, ensuring the water quality meets standards for safe drinking or specific usage requirements. The tankless water dispenser instantly heats or cools the purified water, allowing users to accurately obtain drinking water and meet their different drinking temperature needs. It should be noted that the water purifier, tankless water dispenser, and faucet are all relatively mature existing technologies in the field, and this application does not make significant improvements to the water purifier, tankless water dispenser, and faucet. Therefore, this application does not provide a detailed description of the structure of the water purifier, tankless water dispenser, and faucet, nor does it limit the type and model of the water purifier and tankless water dispenser.

[0088] Considering that water pressure in the water supply pipeline may fluctuate due to various factors (such as peak water supply periods, pipeline maintenance, etc.), a pressure reducing valve is usually installed before the water inlet of the water purifier. This not only stabilizes the water pressure in the supply pipeline but also pre-reduces the water pressure entering the water purifier, preventing physical damage caused by excessive water pressure. To simultaneously distribute purified water to both the tankless water dispenser and the faucet, improving water utilization efficiency, a diversion valve is usually installed at the outlet of the water purifier. Both the inlet of the tankless water dispenser and the faucet's inlet are connected to the diversion valve. When users need to obtain drinking water at a suitable temperature, such as ice water (5℃~15℃) in hot summer, warm water (40℃~50℃) for making formula, or hot water (90℃~99℃) for brewing tea, they can turn on the tankless water dispenser. When users need to use domestic water to rinse tableware, vegetables, fruits, or clothes, they can turn on the tap to use it.

[0089] In a water purification system, the pressure reducing valve and the diverter valve are configured independently. This not only occupies more space, leading to a cluttered piping layout and increased installation difficulty, but also requires separate testing and repair of the pressure reducing valve and the diverter valve when a malfunction occurs. Replacing the pressure reducing valve and / or the diverter valve within a limited space also significantly increases the complexity of operation and maintenance costs.

[0090] Based on this, this application provides a water purification system, which further includes a distributor 1. The faucet, tankless water dispenser, water purifier, and water supply pipe are all connected to the distributor 1, so that the water supply pipe can introduce tap water into the distributor 1 and regulate the excessively high and unstable water pressure of the tap water in the water supply pipe and keep it within the range of the preset pressure value. Finally, stable pressure water is generated and delivered to the water purifier. The water purifier performs deep filtration and purification treatment on the stable pressure water to generate pure water, which flows back to the distributor 1. Through the distributor 1, the pure water flowing to the faucet will be used as domestic water, while the pure water flowing to the tankless water dispenser will be used as drinking water.

[0091] Specifically, please refer to Figures 1 to 5As shown, the diverter 1 includes a valve housing 11, which includes an upper valve body shell 116 and a lower valve body shell 117 that are connected to each other. The connection here should be understood as a detachable connection, such as a bolt connection or a snap-fit ​​connection, so as to facilitate the production of the upper valve body shell 116 and the lower valve body shell 117, and also to effectively improve assembly efficiency and reduce assembly difficulty. In this embodiment, the upper valve body 116 and the lower valve body 117 form an inlet chamber 1147, a return chamber 1146, and an outlet chamber 1148. The outlet chamber 1148 can communicate with the inlet chamber 1147 through the return chamber 1146. The inlet chamber 1147 and the outlet chamber 1148 are preferably located on the top side of the return chamber 1146. The upper valve body 116 is a one-piece molded component, and / or the lower valve body 117 is a one-piece molded component. Therefore, the valve body 11 assembled with the upper valve body 116 and the lower valve body 117 is more stable and has higher structural strength. Thus, when subjected to high-pressure fluid, the pressure can be evenly distributed in all parts of the valve body 11, effectively preventing the valve body 11 from rupturing. When subjected to external impacts, it can better resist deformation. Compared to a combination of independent pressure reducing valves and diverter valves, this type of diverter 1 is less likely to loosen or detach, reducing the risk of leakage and improving its sealing performance. This ensures more stable sealing of the water purification system during long-term use and simplifies the number of piping components (such as valves and conduits) and pipe connections, thereby reducing the difficulty of installation and subsequent maintenance. Furthermore, the one-piece molding technology allows for the manufacture of the valve body through precise molds or processing techniques, enabling better control over the dimensional and shape accuracy of the valve shell 11.

[0092] In this embodiment, please refer to the following for details. Figures 1 to 4As shown, the diverter 1 is equipped with a raw water inlet 1141, a pure water inlet 1143, a raw water outlet 1142, a first water supply port 1144, and a second water supply port 1145. The raw water inlet 1141 is used to connect to the water supply pipe to introduce tap water into the inlet chamber 1147 of the valve body 11. The raw water outlet 1142 is used to connect to the water purifier to deliver the pressure-stabilized water that has flowed through the inlet chamber 1147 and undergone pressure stabilization treatment to the water purifier. The pure water inlet 1143 is used to connect to the water purifier to introduce pure water that has been purified by the water purifier. The first water supply port 1144 is used to connect to the tankless water dispenser to deliver pure water to the tankless water dispenser. The second water supply port 1145 is used to connect to the faucet to deliver pure water to the faucet. The raw water inlet 1141 is connected to the inlet chamber 1147, the raw water outlet 1142 is connected to the return chamber 1146, and the pure water inlet 1143, the first water supply port 1144, and the second water supply port 1145 are all connected to the outlet chamber 1148. Preferably, the raw water outlet 1142, the pure water inlet 1143, and the second water supply port 1145 are all located in the lower shell 117 of the valve body, and the raw water inlet 1141 and the first water supply port 1144 are located in the upper shell 116 of the valve body.

[0093] Furthermore, such as Figure 3 and Figure 4 As shown, the diverter 1 includes a pressure regulating component 16 and a diverting component 17. The pressure regulating component 16 is located in the inlet chamber 1147, and the diverting component 17 is located in the outlet chamber 1148. Thus, tap water supplied by the water supply pipeline flows into the inlet chamber 1147 from the raw water inlet 1141. If the water pressure in the urban water supply network changes due to various factors (such as peak and off-peak water usage, maintenance and adjustments of the water supply system, etc.), for example, the water pressure is lower during peak water usage periods and relatively higher during off-peak periods such as at night, the pressure regulating component 16 can reduce / stabilize the tap water flowing into the inlet chamber 1147 to a stable pressure before outputting it to the water purifier through the raw water outlet 1142 for filtration and purification. This stabilizes the tap water pressure within a suitable range, avoiding the risk of overpressure damage or leakage to the filter cartridges, water purification pipes, and other precision components inside the water purifier due to high water pressure, thereby improving the service life of the water purifier. In addition, tap water flows through the water purifier's filter at a relatively stable rate, allowing the filter to fully absorb impurities such as organic matter and residual chlorine from the tap water, ensuring that the water purifier always maintains the best filtration effect.

[0094] Understandably, such as Figure 4As shown, the water purifier performs deep filtration and purification on the pressure-stabilized water to produce pure water. This pure water then flows through the pure water inlet 1143 of the distributor 1 and into the outlet chamber 1148. Through the cooperation between the outlet chamber 1148 and the distributor assembly 17, the pure water can be distributed according to actual needs, flowing from the first water supply port 1144 to the tankless water dispenser, and from the second water supply port 1145 to the faucet. During the pure water distribution, excess pure water in the outlet chamber 1148 can flow back to the return chamber 1146 under the regulation of the distributor assembly 17, forming excess water. The return chamber 1146 can combine the pressure-stabilized water (after pressure regulation by the pressure regulating assembly 16) with the excess water returning from the distributor assembly 17, and output it to the water purifier from the raw water outlet 1142.

[0095] Next, the specific structure of the voltage regulating component 16 will be described in detail with reference to the accompanying drawings.

[0096] Please refer to the specific details. Figure 3 , Figure 4 and Figure 5 As shown, the pressure regulating component 16 divides the water inlet chamber 1147 into an air chamber 1153 and a liquid chamber 1611. Specifically, the space enclosed by the valve body upper shell 116 and the pressure regulating component 16 forms the air chamber 1153. The pressure regulating component 16 is provided with a water injection guide hole 1612 and a pressure regulating outlet 1613, both of which are connected to the liquid chamber 1611.

[0097] Furthermore, please refer to the specific details. Figure 3 , Figure 4 and Figure 5As shown, the inner wall of the air cavity 1153 extends into the air cavity 1153 and is provided with a water injection conduit 1154 that connects to the raw water inlet 1141. The water injection conduit 1154 is inserted into the water injection guide hole 1612 of the pressure regulating component 16. Specifically, the interior of the water injection conduit 1154 is provided with a water injection channel 1155 that connects to the raw water inlet 1141. The water injection conduit 1154 connects to the liquid cavity 1611 through the water injection channel 1155, and the port of the water injection channel 1155 that connects to the liquid cavity 1611 is a water inlet. A pressure-reducing chamber outlet 1151 is provided on the valve housing 11, allowing the liquid chamber 1611 to connect to the return chamber 1146 through the pressure-reducing chamber outlet 1151. Therefore, the water pressure on the side of the liquid chamber 1611 near the pressure-regulating outlet 1613 is equal to the water pressure in the return chamber 1146. In other words, the outlet pressure on the side of the pressure-regulating assembly 16 near the pressure-regulating outlet 1613 is equivalent to the pressure of the stabilizing water supplied to the water purifier. The water pressure on the side of the liquid chamber 1611 near the water inlet guide hole 1612 is equal to the water pressure in the water supply pipe. In other words, the inlet pressure on the side of the pressure-regulating assembly 16 near the water inlet guide hole 1612 is the same as the water pressure in the water supply pipe. This is because the pressure-regulating assembly 16 includes a pressure-regulating actuator located inside the liquid chamber 1611. Thus, when a pressure difference is formed between the pressure regulating outlet 1613 and the water injection guide hole 1612, the pressure regulating component 16 can generate a relative displacement along the central axis of the water injection guide section 1154 to change the throttling distance between the water inlet and the pressure regulating actuator.

[0098] Understandable, such as Figure 5 As shown, the entire process of tap water flowing into the liquid chamber 1611 is as follows: After tap water flows into the water injection channel 1155 from the raw water inlet 1141, it will flow sequentially through the water inlet port, the water injection guide hole 1612, the pressure regulating outlet 1613, the pressure reducing chamber outlet 1151, and then flow into the return chamber 1146. When the outlet pressure of the pressure regulating component 16 increases (e.g., when the water purifier is turned off), the pressure on the side of the pressure regulating outlet 1613 will drive the pressure regulating component 16 to displace along the central axis of the water injection conduit 1154 towards the side closer to the water inlet port. Then, the pressure regulating actuator of the pressure regulating component 16 moves towards the water inlet port, reducing the throttling distance between the water inlet port and the pressure regulating actuator. In other words, the flow area between the water inlet port and the pressure regulating actuator is reduced until the force balance is reached. When the outlet pressure drops (e.g., when the water purifier is turned on), the pressure on one side of the water inlet guide hole 1612 will drive the pressure regulating component 16 to move along the central axis of the water inlet conduit 1154 and toward the side away from the water inlet port. The pressure regulating actuator of the pressure regulating component 16 moves away from the water inlet port, which increases the throttling distance between the water inlet port and the pressure regulating actuator until the pressure regulating actuator is back in a state of force balance.

[0099] Therefore, as the outlet pressure changes, the pressure regulating component 16 automatically shifts to alter the throttling distance between the water inlet port and the pressure regulating actuator, achieving pressure stabilization and ensuring that the pressure supplied to the water purifier remains essentially constant. The structure is simple and compact, facilitating disassembly and maintenance by subsequent personnel. Furthermore, because the water injection conduit 1154 is inserted into the water injection guide hole 1612 of the pressure regulating component 16, it not only makes the pressure regulating component 16 more stable during displacement but also ensures that the pressure regulating actuator moves precisely towards or away from the water inlet port, thereby accurately adjusting the throttling distance between the water inlet port and the pressure regulating actuator to achieve precise pressure control. During the assembly of the pressure regulating component 16 to the valve housing 11, the water injection conduit 1154 also positions the pressure regulating component 16, improving assembly efficiency and positioning accuracy.

[0100] The unexpected effect is that, for details please refer to... Figure 3 and Figure 5 As shown, tap water flowing in from the raw water inlet 1141 is guided into the liquid chamber 1611 by the water injection channel 1155, but does not fill the entire inlet chamber 1147. This not only makes the pressure regulation response more timely and accurate, but also further reduces the probability of tap water leaking out from the assembly position between the pressure regulating component 16 and the valve housing 11, thereby improving the structural stability and reliability of the diverter 1.

[0101] Please refer to the specific details. Figure 3 As shown, the pressure regulating assembly 16 includes a valve core assembly 162 and a resilient pressure regulating elastic element 163. The pressure regulating elastic element 163 is made of a material capable of elastic deformation (e.g., silicone, rubber). The water inlet 1612 and the pressure regulating outlet 1613 are both located on the valve core assembly 162. The valve core assembly 162 and the pressure regulating elastic element 163 are detachably connected, facilitating their assembly and disassembly. If the pressure regulating elastic element 163 becomes damaged or loses its elasticity after long-term use, it can be replaced individually, reducing the maintenance cost of the pressure regulating assembly 16. Figure 4 As shown, the pressure regulating elastic element 163 is connected between the upper shell 116 and the lower shell 117 of the valve body. Furthermore, when a pressure difference is formed between the pressure regulating outlet 1613 and the water injection guide hole 1612, the pressure regulating elastic element 163 can deform, and the valve core assembly 162 forms relative sliding along the extension direction of the water injection guide section 1154.

[0102] Understandably, when the outlet pressure on the pressure regulating outlet 1613 side of the valve core assembly 162 increases, the pressure regulating elastic element 163 undergoes elastic deformation towards the side closer to the water inlet port under the action of the outlet pressure. At the same time, it also moves along the central axis of the water injection conduit 1154 towards the side closer to the water inlet port in coordination with the valve core assembly 162. When the inlet pressure on the water injection guide hole 1612 side of the valve core assembly 162 decreases, the pressure regulating elastic element 163 resets towards the side away from the water inlet port under the action of the outlet pressure and the deformation recovery of the pressure regulating elastic element 163. At the same time, it also moves along the central axis of the water injection conduit 1154 towards the side away from the water inlet port in coordination with the valve core assembly 162.

[0103] As a preferred embodiment, please refer to the following for details. Figure 5 As shown, the valve core assembly 162 includes a valve core limiting sleeve 1621 and a valve core base 1622. The valve core limiting sleeve 1621 has a first guide hole 16121, and the valve core base 1622 has a second guide hole 16122. The first guide hole 16121 and the second guide hole 16122 constitute a water injection guide hole 1612. The central axis of the first guide hole 16121 and the central axis of the second guide hole 16122 are collinear, ensuring that the water injection conduit 1154 can sequentially pass through the first guide hole 16121 and the second guide hole 16122. A pressure regulating outlet 1613 is located on the valve core base 1622. Further, as... Figure 12 and Figure 13 As shown, the valve core limiting sleeve 1621 is sleeved on the outside of the valve core base 1622, and part of the pressure regulating elastic element 163 is sandwiched between the valve core limiting sleeve 1621 and the valve core base 1622. Preferably, the valve core base 1622 is provided with an external thread section 1625, and the valve core limiting sleeve 1621 is provided with an internal thread section 1626 that is threadedly connected to the external thread section 1625. Thus, the valve core limiting sleeve 1621 and the valve core base 1622 are screwed and fixed. This not only achieves the purpose of detachable connection between the valve core assembly 162 and the pressure regulating elastic element 163, but also makes assembly more convenient and efficient.

[0104] Specifically, such as Figure 5 As shown, the inner diameter of the port of the valve core limiting sleeve 1621 near the pressure regulating elastic element 163 is larger than the diameter of the valve core base 1622. Therefore, a clamping space is formed between the end of the valve core limiting sleeve 1621 near the pressure regulating elastic element 163 and the outer wall of the valve core base 1622. Further details can be found in the attached diagram. Figure 12 , Figure 13 and Figure 14As shown, the aforementioned pressure regulating elastic element 163 includes an elastic element body 1631 and a clamping protrusion 1632 extending from the elastic element body 1631 toward the clamping space. Both the elastic element body 1631 and the clamping protrusion 1632 extend circumferentially along the valve core base 1622. The end of the elastic element body 1631 near the valve core base 1622 and the clamping protrusion 1632 are formed together to form an elastic sleeve hole 164. The valve core base 1622 is inserted into the elastic sleeve hole 164 of the pressure regulating elastic element 163, and the clamping protrusion 1632 is clamped between the valve core limiting sleeve 1621 and the valve core base 1622. With this configuration, the valve core limiting sleeve 1621 and the valve core base 1622 cooperate to clamp the pressure regulating elastic element 163, making the connection between the pressure regulating elastic element 163 and the valve core assembly 162 more stable. This ensures that the pressure regulating elastic element 163 will not detach from the valve core assembly 162 during the elastic deformation of the pressure regulating elastic element 163 and the movement of the valve core assembly 162, thereby improving the stability of the pressure regulating assembly 16 during operation.

[0105] Further details are available according to... Figure 14 As shown, a second fastening protrusion 16332 is provided on the clamping protrusion 1632. The second fastening protrusion 16332 is integrally formed with the clamping protrusion 1632. The second fastening protrusion 16332 is clamped between the clamping protrusion 1632 and the valve core limiting sleeve 1621, thereby increasing the frictional resistance between the clamping protrusion 1632 and the valve core limiting sleeve 1621, effectively preventing the clamping protrusion 1632 from detaching from the clamping space. Of course, the second fastening protrusion 16332 can also be provided on the valve core limiting sleeve 1621. The valve core limiting sleeve 1621 is integrally formed with the second fastening protrusion 16332, which can also increase the frictional resistance between the clamping protrusion 1632 and the valve core limiting sleeve 1621.

[0106] Further details are available according to... Figure 14 As shown, the clamping protrusion 1632 is also provided with a third fastening protrusion 16333, which is integrally formed with the clamping protrusion 1632. The third fastening protrusion 16333 is clamped between the clamping protrusion 1632 and the valve core base 1622, thereby increasing the frictional resistance between the clamping protrusion 1632 and the valve core base 1622, and further preventing the clamping protrusion 1632 from detaching from the clamping space. Of course, the third fastening protrusion 16333 can also be provided on the valve core base 1622, and the third fastening protrusion 16333 is integrally formed with the valve core base 1622, which can also increase the frictional resistance between the clamping protrusion 1632 and the valve core base 1622.

[0107] It should be noted that the second fastening protrusion 16332 can be combined with the third fastening protrusion 16333, which can not only better prevent the clamping protrusion 1632 from detaching from the clamping space, but also make the clamping protrusion 1632 more compactly assembled in the clamping space.

[0108] In addition, please refer to the specific details. Figure 5 As shown, the pressure regulating assembly 16 also includes a valve core sealing ring 165. The valve core limiting sleeve 1621 and the valve core base 1622 cooperate to form a valve core sealing cavity. The valve core sealing ring 165 is sleeved on the water injection conduit 1154 and embedded inside the valve core sealing cavity to better prevent tap water from seeping out from between the water injection guide hole 1612 and the water injection conduit 1154 into the air cavity 1153.

[0109] In this embodiment, to ensure that the pressure regulating elastic element 163 can be connected more quickly and securely between the upper valve body 116 and the lower valve body 117, the inventors have provided a preferred method, which can be found in conjunction with [the following text is missing from the original] Figures 1 to 5 As shown, the aforementioned elastic element body 1631 is snapped between the upper valve body shell 116 and the lower valve body shell 117. Specifically, please refer to... Figure 14 As shown, the lower valve body 117 is provided with a housing groove, which extends circumferentially along the lower valve body 117. The pressure regulating elastic element 163 extends into the housing groove to form a sealing fastening part 1635, which extends along the length of the housing groove and is inserted into the housing groove. This arrangement not only ensures that the pressure regulating elastic element 163 is more compactly and firmly fastened to the valve body 11, facilitating the assembly of the pressure regulating component 16, but also ensures that the pressure regulating component 16 is more securely installed on the valve body 11. Simultaneously, it ensures the sealing of the connection between the pressure regulating elastic element 163 and the valve body 11, preventing water from seeping out of the valve body 11 and avoiding water infiltration into the air cavity 1153, which could lead to rust and failure of the components in the air cavity 1153. It should be noted that the housing slot can also be provided on the upper housing 116 of the valve body, or both the upper housing 116 and the lower housing 117 of the valve body can be provided with housing slots, which can be set and adjusted according to the structural design and design requirements.

[0110] Further details are available according to... Figure 14As shown, a first fastening protrusion 16331 is provided on the sealing fastening part 1635. The first fastening protrusion 16331 is integrally formed with the sealing fastening part 1635. The first fastening protrusion 16331 is sandwiched between the sealing fastening part 1635 and the housing groove, thereby increasing the frictional resistance between the sealing fastening part 1635 and the housing groove, making the sealing fastening part 1635 more securely inserted into the housing groove, and better preventing the sealing fastening part 1635 from detaching from the housing groove. Of course, the first fastening protrusion 16331 can also be provided on the groove wall of the housing groove, which can also increase the frictional resistance between the sealing fastening part 1635 and the housing groove.

[0111] As a preferred embodiment of this invention, please refer to [link / reference]. Figure 14 As shown, the elastic element body 1631 is provided with a deformation adjustment groove 1634, which has a U-shaped structure, and the opening of the deformation adjustment groove 1634 preferably faces the air cavity 1153. Figure 5 As shown, the deformation adjustment groove 1634 is formed by bending the elastic element body 1631 at the position between the valve core base 1622 and the valve housing 11, and the deformation adjustment groove 1634 extends circumferentially along the valve core base 1622. This not only provides sufficient space for the elastic element body 1631 during elastic deformation, but also provides a larger elastic deformation range within a limited space, increasing the elastic capacity of the pressure regulating elastic element 163.

[0112] As a preferred embodiment, please refer to the following for details. Figure 12 As shown, the valve core base 1622 includes a valve disc plug 1623, which serves as the pressure regulating actuator of the pressure regulating assembly 16. Figure 13 As shown, a valve disc support beam 1624 extends from the valve disc plug 1623 toward the wall of the liquid chamber 1611. The valve disc support beam 1624 extends to the body of the valve core base 1622 and is fixedly connected to the body of the valve core base 1622. To ensure good structural strength of the valve core base 1622 and to facilitate its production, the valve disc plug 1623, the valve disc support beam 1624, and the body of the valve core base 1622 are integrally formed. The valve disc support beam 1624 can be selected as one beam, extending circumferentially along the valve disc plug 1623. Multiple water flow holes are evenly arranged on the valve disc support beam 1624 along the circumferential direction of the valve disc plug 1623, allowing pressure-stabilized water to flow through the water flow holes. Alternatively, there are preferably multiple valve disc support beams 1624, which are evenly distributed around the valve disc plug 1623, and adjacent valve disc support beams 1624 are spaced apart to allow pressure-stabilizing water to flow through the circumference of the valve disc plug 1623.

[0113] To avoid rigid contact between the valve plug 1623 and the water inlet of the water inlet pipe 1154, and to reduce the noise of the distributor 1, please refer to the following for details. Figure 5 , Figure 12 and Figure 13 As shown, the valve disc plug 1623 includes a valve disc support 16231 and an elastic plug element 16232. The elastic plug element 16232 can be made of silicone. The valve disc support 16231 is provided with a valve disc insertion groove 16233 for embedding the elastic plug element 16232. The valve disc support 16231 is fixedly connected to the body of the valve core base 1622 through the valve disc support beam 1624.

[0114] In this embodiment, please refer to the following for details. Figures 3 to 5 As shown, the pressure regulating assembly 16 also includes a pressure regulating spring 166, which is located in the air cavity 1153. One end of the pressure regulating spring 166 abuts against the inner wall of the air cavity 1153, and the other end of the pressure regulating spring 166 abuts against the valve core assembly 162. When a pressure difference is formed between the pressure regulating outlet 1613 and the water injection guide hole 1612, both the pressure regulating elastic element 163 and the pressure regulating spring 166 will deform.

[0115] On the one hand, during pressure regulation, the pressure regulating spring 166 can assist the pressure regulating elastic element 163 in returning to its initial or equilibrium position after pressure changes. That is, the pressure regulating spring 166 can use its own elastic force to push the pressure regulating elastic element 163 back to a certain position, causing the valve core assembly 162 to move accordingly and return to a state close to its original state, thereby ensuring the stability of the outlet pressure. Moreover, the elastic coefficient of the pressure regulating spring 166 is relatively stable, which helps to more accurately control the deformation of the pressure regulating elastic element 163, thereby precisely controlling the outlet pressure. On the other hand, the pressure regulating spring 166 can, to a certain extent, share the pressure borne by the pressure regulating elastic element 163, thus avoiding the problem that the pressure regulating elastic element 163 might suffer excessive deformation, fatigue failure, or even damage if it bears the pressure alone when the inlet pressure is too high or when there are frequent starts and stops.

[0116] Furthermore, the combination of the pressure regulating spring 166 and the pressure regulating elastic element 163 allows the valve core assembly 162 to respond more quickly to pressure changes. When the pressure changes, the elastic force of the pressure regulating spring 166 and the deformation force of the pressure regulating elastic element 163 work together to accelerate the movement of the valve core assembly 162, that is, to quickly adjust the throttling distance between the water inlet and the pressure regulating actuator, thereby improving the pressure regulating efficiency of the diverter 1.

[0117] Furthermore, please refer to the specific details. Figures 3 to 5As shown, a pressure regulating limiting platform 1194 is provided on the inner wall of the air cavity 1153 along the extension direction of the water injection conduit 1154. The extension length of the pressure regulating limiting platform 1194 should be less than the extension length of the water injection conduit 1154. The end of the pressure regulating spring 166 is sleeved on the outside of the pressure regulating limiting platform 1194 to achieve the purpose of limiting the pressure regulating spring 166 and improving the positioning accuracy and assembly efficiency of the pressure regulating spring 166 during the assembly process.

[0118] Preferably, please refer to the following for details. Figures 3 to 5 As shown, the valve core assembly 162 can abut against the pressure regulating limit platform 1194 along the central axis of the water injection conduit 1154, thereby sealing and closing the water inlet port at the pressure regulating actuator end. That is, as the valve core assembly 162 moves along the central axis of the water injection conduit 1154 toward the side closer to the water inlet port, when the valve core limiting sleeve 1621 of the valve core assembly 162 abuts against the pressure regulating limit platform 1194, the plug elastic element 16232 of the valve core assembly 162 will also abut against the water inlet port of the water injection conduit 1154, thereby increasing the bearing area and bearing capacity of the diverter 1.

[0119] Further details are available according to... Figure 3 As shown, a breather hole 118 is also provided on the valve housing 11. The air chamber 1153 is connected to the outside of the valve housing 11 through the breather hole 118, allowing the pressure regulating assembly 16 to generate relative displacement along the central axis of the water injection conduit 1154. Understandably, when the pressure regulating elastic element 163 and the pressure regulating spring 166 deform, the internal pressure of the air chamber 1153 will change. At this time, connecting the air chamber 1153 to atmospheric pressure via the breather hole 118 helps maintain stable pressure in the air chamber 1153 where the pressure regulating spring 166 is located. This avoids the risk of excessive deformation and breakage due to the pressure difference on both sides of the pressure regulating elastic element 163 exceeding its bearing capacity, thereby improving the service life of the pressure regulating assembly 16 and the diverter 1. In addition, the pressure inside the air cavity 1153 is kept in communication with the external environment pressure through the breather hole 118. During the process of reducing / regulating the pressure of tap water, it can effectively prevent the pressure from dropping below the saturated vapor pressure of tap water and causing cavitation, thereby avoiding the vibration and noise problems caused by the presence of air bubbles in the distributor 1.

[0120] Preferably, please refer to the following: Figure 3As shown, the breather hole 118 is located on the upper valve body shell 116 of the valve housing 11, and the central axis of the breather hole 118 is parallel to the central axis of the water injection conduit 1154. From a stability perspective, this consistent orientation helps maintain the balance of the air chamber 1153. During operation, when there are slight pressure fluctuations, the pressure regulating spring 166 extends and retracts according to the pressure change. The position of the breather hole 118 allows gas to enter and exit promptly, coordinating with the actions of the pressure regulating spring 166 and the pressure regulating elastic element 163 to quickly adjust the internal pressure. Regarding the accuracy of pressure regulation, when the breather hole 118 and the pressure regulating spring 166 extend and retract in the same direction, the path of gas entering and exiting the breather hole 118 during pressure changes is more matched and coordinated with the path of internal space changes caused by the extension and retraction of the pressure regulating spring 166. This allows for more precise control of the pressure reduction.

[0121] Further details are available according to... Figure 3 As shown, the breather hole 118 is located on the side of the upper shell 116 of the valve body near the edge, and extends along the extension direction of the water injection conduit 1154 to the side of the upper shell 116 of the valve body near the pressure regulating component 16. This effectively ensures that the inner wall of the breather hole 118 is smoother and flatter, making the flow state of gas through the breather hole 118 more stable, effectively avoiding the unstable phenomenon of local turbulence in the gas, thereby ensuring that the air chamber 1153 can more accurately sense pressure changes and adjust the pressure more precisely, improving the accuracy of pressure regulation. Of course, the smooth inner wall also makes it less likely for impurities to accumulate. In some working environments, the fluid may carry tiny particulate impurities, which are easily accumulated at protrusions and may cause the breather hole 118 to become blocked over time. The smooth inner wall makes it difficult for impurities to adhere and accumulate, effectively ensuring the unobstructed flow of the breather hole 118, ensuring the normal breathing function of the air chamber 1153, and thus ensuring the stable operation of the entire distributor 1.

[0122] As a preferred embodiment, please refer to the following for details. Figure 6 and Figure 7As shown, a limiting support post 1191 is provided on the lower valve body shell 117 of the valve housing 11. The limiting support post 1191 is preferably located directly below the valve disc plug 1623, and it protrudes towards the liquid chamber 1611. The pressure regulating actuator of the pressure regulating assembly 16 can abut against the limiting support post 1191, allowing the diverter 1 to limit the pressure regulating actuator of the valve core assembly 162 when it is not in use or when the outlet pressure drops. In other words, the limiting support post 1191 can support the valve core assembly 162. At this time, the throttling distance between the pressure regulating actuator and the water inlet of the water inlet channel 1155 is at its maximum. Furthermore, an anti-sticking protrusion 1192 is provided at the end of the limiting support post 1191 near the pressure regulating actuator, creating a gap between the limiting support post 1191 and the pressure regulating actuator. This is equivalent to reducing the contact area between the limit support column 1191 and the pressure regulating actuator. It can also be understood that the pressure regulating actuator does not directly contact the end of the limit support column 1191. Therefore, when dirt accumulates at the end of the limit support column 1191, the pressure regulating actuator will not stick to the limit support column 1191, effectively preventing the problem of pressure regulating failure of the shunt 1.

[0123] Furthermore, please refer to the specific details. Figure 6 and Figure 7 As shown, the anti-stick protrusions 1192 are distributed at the edge of the end of the limiting support column 1191 and extend along the circumference of the limiting support column 1191. The anti-stick protrusions 1192 are preferably formed into an arc shape extending along the circumference of the limiting support column 1191. Then, the tap water flowing through the limiting support column 1191 can clean the end of the limiting support column 1191 by itself, reducing the probability of dirt accumulation at the end of the limiting support column 1191.

[0124] It should be noted that the anti-sticking protrusion 1192 can also be set on the pressure regulating actuator end, that is, the anti-sticking protrusion 1192 is set on the valve disc support 16231 of the valve disc plug 1623.

[0125] Preferably, the end of the limiting support column 1191 may also be provided with a groove 1193, and the anti-sticking protrusion 1192 is located on the side of the groove 1193. This arrangement effectively increases the gap distance between the limiting support column 1191 and the pressure regulating actuator, thereby further preventing the pressure regulating actuator from sticking to the limiting support column 1191 and improving the stability of the pressure regulation of the diverter 1.

[0126] Furthermore, such as Figure 15As shown, at least one through hole 16234 is provided on the side wall of the valve disc support 16231 near the limiting support column 1191. This not only facilitates the insertion of the plug elastic element 16232 into the valve disc insertion groove 16233 of the valve disc support 16231 and the pushing of the plug elastic element 16232 out of the valve disc insertion groove 16233 of the valve disc support 16231, but also further reduces the contact area of ​​the pressure regulating actuator.

[0127] In the above, the water outlet chamber 1148, together with the diversion component 17, can distribute the purified water after the water purifier is purified. The excess purified water inside the water outlet chamber 1148 can flow back to the return chamber 1146 under the adjustment of the diversion component 17, forming excess water. This effectively prevents the water pressure from fluctuating too much during the sudden use of the tankless water dispenser and / or faucet, which would cause the water purifier to start and stop frequently.

[0128] Next, the specific structure of the above-mentioned shunt component 17 will be described in detail with reference to the accompanying drawings.

[0129] The diversion assembly 17 is provided with a flow-through hole, which is used to guide the pure water flowing in from the pure water inlet 1143 through the diversion assembly 17 and into the outlet chamber 1148. Further details can be found in the following section. Figure 17 The diversion component 17 divides the water outlet chamber 1148 into a lower water outlet chamber 11481 and an upper water outlet chamber 11482. The pure water inlet 1143 and the second water supply port 1145 are both connected to the lower water outlet chamber 11481. The upper water outlet chamber 11482 is connected to the first water supply port 1144. The upper water outlet chamber 11482 is connected to the lower water outlet chamber 11481 through a flow hole. At this time, after the pure water flows from the pure water inlet 1143 into the lower water outlet chamber 11481 for buffering and storage, a portion of it will flow through the flow hole to the upper water outlet chamber 11482 and finally flow out from the first water supply port 1144.

[0130] In addition, such as Figure 24As shown, the valve housing 11 has a return flow guide part 1171, which is located inside the outlet chamber 1148, and the return flow guide part 1171 is provided with a guide flow channel 1172 that communicates with the return flow chamber 1146. Specifically, the return flow guide 1171 is disposed on the lower shell 117 of the valve body and extends toward the outlet chamber 1148. The guide channel 1172 extends to the port of the outlet chamber 11481 and connects to the outlet chamber 11481. The diversion component 17 can abut against the return flow guide 1171. According to the pressure difference formed by the pure water inlet 1143, the first water supply port 1144, and the second water supply port 1145, the diversion component 17 can generate a relative displacement toward the first water supply port 1144, so that the diversion component 17 separates from the return flow guide 1171. Then, excess pure water can flow from the guide channel 1172 into the return chamber 1146, forming the aforementioned excess water.

[0131] Thus, when the faucet is used alone, purified water will flow from the purified water inlet 1143 into the lower outlet chamber 11481, and then flow directly from the lower outlet chamber 11481 out of the second water supply port 1145. At this time, the diversion component 17 abuts against and fits against the return guide part 1171 to seal the guide channel 1172, so that purified water will not flow back to the guide channel 1172.

[0132] When the tankless water dispenser is used alone, purified water flows from the purified water inlet 1143 into the lower outlet chamber 11481, passes through the flow hole, and enters the upper outlet chamber 11482. Finally, it flows out from the first water supply port 1144 to the tankless water dispenser. At this time, the pressure on the side of the diversion assembly 17 near the first water supply port 1144 is less than the pressure on the side of the diversion assembly 17 away from the first water supply port 1144. That is, the water pressure formed by the purified water inlet 1143 and the second water supply port 1145 is greater than the water pressure on the side of the first water supply port 1144. The diversion assembly 17 can generate a relative displacement towards the side of the first water supply port 1144, causing the diversion assembly 17 to separate from the return guide part 1171, and the excess purified water flows back to the guide channel 1172. Understandably, the water output of the first water supply port 1144 is determined by the water pump and negative pressure valve of the tankless water dispenser.

[0133] When the tankless water dispenser is turned off, the diverter assembly 17 will reset towards the return guide section 1171, and then the diverter assembly 17 will re-abut against the return guide section 1171 to reseal the guide flow channel 1172. Therefore, the diverter 1 can flexibly meet the water flow distribution needs of the tankless water dispenser when it is used alone, so that pure water can meet the water needs of the tankless water dispenser while reasonably handling excess water volume, without wasting water resources, and avoiding the risk of damaging the tankless water dispenser due to excessive water pressure.

[0134] When the tankless water dispenser and the faucet are used simultaneously, purified water flows from the purified water inlet 1143 into the lower outlet chamber 11481. Part of the purified water flows out from the second water supply port 1145 to the faucet, while the other part passes through the flow passage into the upper outlet chamber 11482 and flows out from the first water supply port 1144 back to the tankless water dispenser. Because the water pressure on the second water supply port 1145 side decreases, the pressure on the side of the diversion component 17 near the first water supply port 1144 is not significantly different from the pressure on the side of the diversion component 17 away from the first water supply port 1144. At this time, the diversion component 17 abuts against the return guide 1171, so excess purified water hardly flows into the guide channel 1172. This ensures that both the tankless water dispenser and the faucet can use water normally, guaranteeing the stable operation of the entire water purification system.

[0135] Therefore, when only the tankless water dispenser is in use, excess purified water can be returned, preventing the water purifier from frequently adjusting its operating status due to sudden changes in water usage (such as water pressure fluctuations caused by frequent on / off cycles). For example, without a return mechanism, a sudden pressure change when the tankless water dispenser is turned off could impact the internal structure and operating pressure of the water purifier. The return mechanism buffers this pressure change to some extent, reducing the pressure from frequent start-ups and shutdowns. When water is used simultaneously, the diversion component 17 maintains a relatively stable water flow distribution. Without the diversion component 17, if the faucet and tankless water dispenser are operating simultaneously, a sudden change in water usage on one side (such as a sudden faucet shutdown) could cause significant fluctuations in internal water pressure, leading to frequent adjustments in the water purifier's operating status. The diversion component 17 maintains relatively stable water pressure and flow distribution, reducing frequent start-ups and shutdowns caused by changes in external water usage.

[0136] In related technologies, the aforementioned flow-through orifices can elastically expand and contract, and the flow rate of purified water passing through these orifices is adjusted through their minute deformation. That is, when the water consumption of the tankless water dispenser increases, the flow-through orifices enlarge as the pressure difference across the diversion assembly 17 increases, increasing the flow of purified water. When the water consumption of the tankless water dispenser decreases, the flow-through orifices contract under their own rebound force, reducing the flow of purified water, thereby automatically maintaining the pressure difference across the diversion assembly 17 and delaying its reset. However, since the deformation of the flow-through orifices is limited, the maximum and minimum flow range that it can adjust is also greatly limited. For example, when the water consumption of the water terminal varies greatly, the size and deformation of the flow-through orifices limit the actual flow rate adjustment requirements; a flow-through orifice with a small deformation alone will not be able to meet the actual flow rate adjustment needs.

[0137] Based on this, this application provides a flow splitter component 17, which aims to solve the problem in the related art where the flow splitter 1 is limited by the deformation of the flow orifice, thus restricting the maximum and minimum flow range that can be adjusted.

[0138] Please refer to the specific details. Figure 16 As shown, the diversion assembly 17 includes a flexible check valve 1721 with a flow regulating port 1722. This flexible check valve 1721 can control the opening and closing of its flow regulating port 1722 based on the pressure difference formed by the pure water inlet 1143, the first water supply port 1144, and the second water supply port 1145, thereby regulating the increase or decrease in the amount of pure water flowing into the outlet chamber 1148. This increase or decrease should be understood as the physical quantity by which the volumetric flow rate of pure water increases as the flow regulating port 1722 changes in its opening and closing position. That is, the flexible check valve 1721 is elastic. When the water output of the first water inlet 1144 is large, the pressure difference formed by the pure water inlet 1143, the first water inlet 1144, and the second water inlet 1145 is large. The flow regulating port 1722 of the flexible check valve 1721 can open. Then the upper water outlet chamber 11482 will also be connected to the lower water outlet chamber 11481 through the flow regulating port 1722. The cross-sectional area of ​​the flow regulating port 1722 will increase with the increase of the pressure difference until it opens to the maximum deformation state of the flow regulating port 1722. Then the opening and closing size of the flow regulating port 1722 will change from zero to the maximum extent, so that the volume flow rate (hereinafter referred to as flow rate) of pure water through the flow regulating port 1722 can be increased from zero to the maximum extent, so that some pure water will also be supplemented into the upper water outlet chamber 11482 through the flow regulating port 1722. Understandably, when the pressure difference decreases, the flow regulating port 1722 will be able to shrink on its own as the deformation recovers, until it is completely closed. At this time, the pure water will hardly flow through the flow regulating port 1722.

[0139] Therefore, when the water consumption at the water terminal varies significantly, the elastic deformation of the flexible check valve 1721 can alter the increase or decrease in the flow of purified water into the inlet / outlet chamber 1148, effectively solving the problem that the existing diverter 1 is limited by the deformation of the flow orifice, thus restricting the maximum and minimum flow range that can be adjusted. Furthermore, once the opening of the flow regulating port 1722 is adjusted, the flow rate of purified water remains relatively stable. In long-term use, compared to simply having a retractable flow orifice, this reduces the risk of clogging, thereby better ensuring the stability of the diverter assembly 17 and the diverter 1, and lowering manufacturing and maintenance costs.

[0140] It should be noted that the aforementioned elastically expandable flow hole is combined with the flexible check part 1721, that is, the flow hole and the flexible check part 1721 are provided on the flow diversion assembly 17 at the same time.

[0141] Next, the specific structure of the above-mentioned shunt component 17 will be described in detail with reference to the accompanying drawings.

[0142] Please refer to the specific details. Figure 24 As shown, the diversion assembly 17 includes a diversion balancing diaphragm 172 and a balancing spring 171. The diversion balancing diaphragm 172 is detachably connected between the upper valve body shell 116 and the lower valve body shell 117. The upper valve body shell 116 and the diversion balancing diaphragm 172 cooperate to form an upper outlet chamber 11482, and the lower valve body shell 117 and the diversion balancing diaphragm 172 cooperate to form a lower outlet chamber 11481. The balancing spring 171 is disposed between the diversion balancing diaphragm 172 and the inner wall of the upper outlet chamber 11482.

[0143] Please see below. Figures 17 to 21 The diversion balancing membrane 172 is made of an elastic material (such as silicone or rubber). The diversion balancing membrane 172 has diaphragm through-holes 1724, which are also diaphragm through-holes, allowing for elastic expansion and contraction. Furthermore, the flexible check valve 1721 is provided on the diversion balancing membrane 172. The flexible check valve 1721, in conjunction with the through-holes, enables more precise flow control. When the demand for pure water is low, a small pressure difference may cause the through-holes to deform, finely regulating the flow and improving the adjustment accuracy of the diversion component 17 and the diverter 1. When the demand for pure water is high, the flexible check valve 1721 can deform under a large pressure difference, allowing a large amount of pure water to pass through. This combination is equivalent to a multi-stage regulation system, capable of precisely adjusting the flow through the diverter 1 according to different operating conditions (such as different water usage rates in tankless water dispensers), and effectively reducing the probability of frequent start-ups and shutdowns of the water purifier. Meanwhile, through the synergistic effect of the flow-through holes on the flow-balancing membrane 172 and the flexible check valve 1721, the pressure balance on both sides of the flow-dividing assembly 17 can be better maintained. That is, they can flexibly adjust their own state according to the magnitude of the pressure difference on both sides, making the distribution of pure water in the outlet chamber 1148 more stable, which helps to improve the reliability and service life of the flow divider 1 and reduce the damage to its components and system failures caused by pressure imbalance.

[0144] Thus, when the water consumption of the tankless water dispenser is high, the pressure difference between the side of the diversion balancing membrane 172 near the first water supply port 1144 and the side of the diversion assembly 17 away from the first water supply port 1144 is large. The diversion balancing membrane 172 will undergo elastic deformation towards the first water supply port 1144, compressing the balance spring 171. When the water consumption of the tankless water dispenser decreases, the pressure difference between the two sides of the diversion balancing membrane 172 decreases, and there is almost no pure water flow at the first water supply port 1144. This means there is no pressure generated by the pure water flow. At this time, the state of the two sides of the diversion balancing membrane 172 returns to its initial equilibrium state. Under the action of the elastic deformation of the diversion balancing membrane 172 itself and the elastic deformation of the balance spring 171, the side of the diversion balancing membrane 172 away from the first water supply port 1144 deforms and recovers until the diversion balancing membrane 172 abuts against the flexible check valve 1721 to seal the guide channel 1172. This setting will have the following unexpected effects:

[0145] 1. When the water consumption of the tankless water dispenser is high, the pressure difference between the side of the diversion balancing membrane 172 near the first water inlet 1144 and the side of the diversion assembly 17 away from the first water inlet 1144 is significant. The diversion balancing membrane 172 will undergo elastic deformation towards the first water inlet 1144, compressing the balance spring 171. At this time, the balance spring 171 acts as a buffer, absorbing some of the pressure and preventing damage to the diversion balancing membrane 172 due to excessive instantaneous pressure. Conversely, when the water consumption of the tankless water dispenser decreases, the pressure difference between the two sides of the diversion balancing membrane 172 decreases. Since the balance spring 171 stores elastic potential energy after compression, it releases this energy to help the diversion balancing membrane 172 recover its deformation on the side away from the first water inlet 1144.

[0146] 2. The elastic properties of the diversion balancing membrane 172 allow it to automatically adjust the size of the flow orifice according to changes in pressure difference. The balancing spring 171, in conjunction with this, can more precisely control the deformation of the diversion balancing membrane 172, thereby improving the diversion accuracy of the diverter 1. For example, when the pressure difference changes slightly, the slight deformation of the diversion balancing membrane 172 and the slight extension and contraction of the balancing spring 171 work together to more accurately regulate the flow of pure water, thus better achieving the function of automatically maintaining the pressure difference across the diversion balancing membrane 172.

[0147] 3. During the entire use of the tankless water dispenser, the water consumption is dynamically changing. The balance spring 171 and the diversion balance membrane 172 work together to effectively regulate the internal pressure balance of the water dispenser under different water usage conditions. This cooperation allows the diverter 1 to adapt to complex and changing operating conditions, reducing system failures caused by factors such as sudden pressure changes, enhancing the stability and reliability of the system, and extending the service life of the diverter 1. Furthermore, when the water consumption of the tankless water dispenser changes rapidly, the synergistic effect of the balance spring 171 and the diversion balance membrane 172 allows the diverter 1 to respond quickly. For example, when the water consumption of the tankless water dispenser suddenly increases, the balance spring 171 can quickly buffer the deformation of the diversion balance membrane 172, causing the flexible check valve 1721 to expand rapidly and increase the water flow. Conversely, when the water consumption of the tankless water dispenser suddenly decreases, both mechanisms can promptly reset the diversion balance membrane 172, reducing the flow of purified water, thereby optimizing the dynamic response capability of the diversion process.

[0148] It should be further explained that, please refer to the specific details. Figure 21 As shown, the aforementioned flexible check valve 1721 has a duckbill-shaped structure. A duckbill cavity 1723 is provided inside the flexible check valve 1721. The duckbill cavity 1723 passes through the diversion balancing membrane 172, and a duckbill opening is formed on the side of the diversion balancing membrane 172 facing away from the flexible check valve 1721. For details, please refer to... Figures 17 to 21 The flexible check valve 1721 includes a duckbill-shaped deformation portion 17211 and a base 17212 fixedly connected to the diversion balancing membrane 172. The duckbill-shaped deformation portion 17211, the base 17212, and the diversion balancing membrane 172 are integrally formed to facilitate processing and manufacturing, and also to ensure the integrity of the diversion balancing membrane 172, so that the diversion balancing membrane 172 has good comprehensive properties (such as elasticity). The duckbill-shaped deformation portion 17211 extends from the base 1721. 2. The upper cavity 11482 of the water outlet is convex, and the cross-sectional area of ​​the duckbill deformation part 17211 gradually decreases along the convex direction. The cross-section here is parallel to the large surface of the diversion balance membrane 172. The large surface of the diversion balance membrane 172 is the side with the largest area in the diversion balance membrane 172. The flow regulating port 1722 is located at the end of the duckbill deformation part 17211 away from the diversion balance membrane 172, and the duckbill cavity 1723 is connected to the flow regulating port 1722.

[0149] As a preferred embodiment, please refer to the following for details. Figure 16 , Figure 17 , Figure 18 and Figure 21As shown, the aforementioned diversion assembly 17 also includes a diaphragm top cover 173. The diaphragm top cover 173 has a top cover through hole 1731, which connects to the diaphragm through hole 1724. In this case, the top cover through hole 1731 and the diaphragm through hole 1724 constitute the aforementioned flow passage. The diaphragm top cover 173 is located on the side of the diversion balancing membrane 172 near the first water supply port 1144, and the aforementioned flexible check valve 1721 protrudes towards the diaphragm top cover 173 and passes through the diaphragm top cover 173. That is, as shown... Figure 17 and Figure 18 As shown, the diaphragm top cover 173 is provided with a top cover through hole 1732. The duckbill-shaped portion 17211 of the flexible check portion 1721 passes through the top cover through hole 1732 and protrudes from the top cover through hole 1732 towards the upper water outlet cavity 11482. One end of the balance spring 171 abuts against the inner wall of the upper water outlet cavity 11482, and the other end of the balance spring 171 abuts against the diaphragm top cover 173. In this way, the diaphragm top cover 173 serves as a support point for the balance spring 171, and the diaphragm top cover 173 has good structural strength. During the diversion process, the balance spring 171 can adjust the system balance through the force between the diaphragm top cover 173 and the inner wall. For example, when the flow rate of pure water changes or the internal pressure of the upper water outlet cavity 11482 fluctuates, the balance spring 171 can extend and retract according to the position change of the diaphragm top cover 173, thereby adjusting the pressure balance and flow balance of the diverter 1 and ensuring the stability of the diversion.

[0150] Further details are available according to... Figure 16 As shown, the diversion assembly 17 has a stop and limiting part 1733 protruding towards the first water supply port 1144. When the diversion assembly 17 moves relative to the first water supply port 1144, the stop and limiting part 1733 abuts against the inner wall of the outlet chamber 1148. Specifically, the stop and limiting part 1733 abuts against the inner wall of the upper outlet chamber 11482. At this point, the diversion assembly 17 has reached its maximum displacement. This ensures that even under a large pressure difference, the stop and limiting part 1733 can abut against the inner wall of the upper outlet chamber 11482, forming a reliable mechanical limit. This effectively restricts further movement of the diversion assembly 17, preventing excessive deformation of the diversion balancing membrane 172 due to excessive force. It also eliminates the risk of damage to the diversion balancing membrane 172 due to excessive deformation, thus improving the service life of the diverter 1.

[0151] Preferably, please refer to the following for details. Figure 17 , Figure 18 and Figure 21As shown, the stop and limit part 1733 is disposed on the diaphragm top cover 173. Preferably, the stop and limit part 1733 is integrally formed with the diaphragm top cover 173. The stop and limit part 1733 can withstand the impact force generated by collision with the inner wall of the outlet upper cavity 11482. Because the diaphragm top cover 173 has good structural strength, it can ensure that the stop and limit part 1733 will not easily deform or be damaged during frequent displacement and collisions, thereby better maintaining the stability and accuracy of the entire diverter 1. In other embodiments, the stop and limit part 1733 can also be disposed on the diversion balance membrane 172.

[0152] The unexpected effect is that, Figures 17 to 21 As shown, the stop and limit part 1733 is located outside the balance spring 171 and extends circumferentially along the balance spring 171 to constrain the end of the balance spring 171 to the inside of the stop and limit part 1733, thereby ensuring the stability of the balance spring 171 during deformation. It should be noted that the inner diameter of the stop and limit part 1733 can be adapted to the outer diameter of the balance spring 171; alternatively, the inner diameter of the stop and limit part 1733 can be larger than the outer diameter of the balance spring 171. Furthermore, a spring limiting post 1734 can be protruded from the diaphragm top cover 173 facing the first water inlet 1144, and the end of the balance spring 171 is fitted onto the spring limiting post 1734. This, in conjunction with the stop and limit part 1733, achieves a dual constraint on the balance spring 171. In addition, the spring limiting post 1734 can also quickly position the balance spring 171 during assembly, improving assembly efficiency.

[0153] Further details are available according to... Figure 17 As shown, the stop and limit part 1733 is provided with a clearance opening 1735 corresponding to the flexible check part 1721. For example... Figure 20 As shown, the clearance 1735 preferably extends through the stop 1733 along the protruding direction of the stop 1733, so that the stop 1733 is formed into two arc-shaped and oppositely arranged stop portions. Therefore, the number of flexible stop portions 1721 is two, and each flexible stop portion 1721 is located between the two stop portions. This arrangement will have the following unexpected technical effects:

[0154] 1. The clearance opening 1735 provides space for the flexible check valve 1721, allowing the flexible check valve 1721 to protrude and pass through the diaphragm top cover 173 normally. At the same time, it also ensures that each flexible check valve 1721 can deform according to the water flow pressure within a limited space, thereby flexibly adjusting the water flow distribution.

[0155] 2. Under the action of the clearance port 1735, the flexible check portion 1721 on the diaphragm top cover 173 and the diversion balance membrane 172 can avoid mutual compression and friction during operation, effectively reducing interference and wear between the flexible check portion 1721 and the stop limiting portion 1733, thereby improving the service life of the diversion assembly 17. This improves the reliability and durability of the diversion balance membrane 172 and the diversion assembly 17.

[0156] 3. The flexible check valve 1721 is configured in pairs, allowing them to work together under different water pressure and flow conditions. For example, when water impacts the flow-dividing balancing membrane 172, if there is only one flexible check valve 1721, it may deform to one side due to the uneven impact of the water flow, leading to unstable flow division. Two relatively distributed flexible check valves 1721 can balance this impact force. When one flexible check valve 1721 is subjected to greater water pressure and tends to open, the other flexible check valve 1721 can adjust accordingly based on the pressure difference, thereby maintaining the stability of the flow division and making the water flow from the first water inlet 1144 more uniform and stable.

[0157] 4. Under the action of the clearance port 1735, when the stop and limit part 1733 abuts against the inner wall of the water outlet upper cavity 11482, it can still maintain the flow of pure water through the clearance port 1735 to the first water supply port 1144, ensuring the smoothness, stability and continuity of the pure water flow, and effectively preventing the pure water from being blocked by the stop and limit part 1733, which would cause a sudden change in water pressure, thus ensuring the stability and reliability of the use of the diverter 1 and the drinking water system.

[0158] Considering that when the stop limiting part 1733 abuts against the inner wall of the water outlet upper cavity 11482, the water output of the first water supply port 1144 is relatively large, that is, the pure water demand of the tankless water dispenser is large. In order to further ensure the supply of pure water, the stop limiting part 1733 is provided with a water passage notch 1736. That is, each stop part of the stop limiting part 1733 is provided with a water passage notch 1736 near the end of the first water supply port 1144. In this embodiment, the shape and size of the water passage notch 1736 are not limited, and can be adjusted according to design requirements and structural design. Then, some pure water can also flow to the first water supply port 1144 through the water passage notch 1736, thereby ensuring that sufficient pure water flows to the first water supply port 1144 and is supplied to the tankless water dispenser.

[0159] Of course, it should also be noted that, in addition to the stop and limit part 1733 on the diversion assembly 17 abutting against the inner wall of the outlet upper cavity 11482, please refer to the specific details. Figure 24As shown, a stop boss 1161 is formed on the inner wall of the upper outlet cavity 11482 facing the diversion assembly 17. Specifically, the stop boss 1161 is formed on the inner wall of the upper outlet cavity 11482 facing the diversion assembly 17. The stop boss 1161 is preferably integrally formed with the upper shell 116 of the valve body for ease of manufacturing. The interior of the stop boss 1161 is provided with a first water supply channel 1162 that communicates with the first water supply port 1144, and the stop limiting part 1733 can abut against the stop boss 1161.

[0160] On the one hand, the stop protrusion 1161 cooperates with the stop limiting part 1733 on the diaphragm top cover 173 to more precisely limit the deformation of the diversion balancing membrane 172. When the diversion balancing membrane 172 deforms towards the first water supply port 1144 under the action of water flow, water pressure and other factors, the stop limiting part 1733 abuts against the stop protrusion 1161, thereby further preventing excessive deformation of the diversion balancing membrane 172 and better ensuring that the diversion balancing membrane 172 works within a safe range. On the other hand, pure water will be orderly guided to the first water supply port 1144 through the first water supply channel 1162, so that the water flow is more concentrated and stable towards the target outlet, avoiding water flow turbulence, thereby improving the working efficiency and accuracy of the diverter 1.

[0161] Preferably, please refer to the following: Figure 24 As shown, a spring receiving body 1163 is protruding from the inner wall of the first water supply channel 1162. The spring receiving body 1163 may extend circumferentially along the first water supply channel 1162, or multiple spring receiving bodies 1163 may be configured. Each spring receiving body 1163 may be hemispherical or prismatic, and multiple spring receiving bodies 1163 are arranged circumferentially along the first water supply channel 1162. Figure 16 As shown, the end of the balance spring 171 is inserted into the first water supply channel 1162, and the end of the balance spring 171 abuts against the spring force-bearing body 1163. At this time, the spring force-bearing body 1163 provides a fixed support point for the end of the balance spring 171, making the position of the balance spring 171 more stable during operation. That is, the end of the balance spring 171 abuts against the spring force-bearing body 1163, while the periphery of the balance spring 171 can contact the inner wall of the flow channel of the first water supply channel 1162. This effectively avoids vibration or slight displacement that the balance spring 171 may generate during operation, thereby better ensuring that the balance spring 171 can perform its balancing and regulating functions normally, and transmit force more accurately, ensuring and improving the flow distribution accuracy of the diverter 1.

[0162] Of course, to facilitate the assembly of the end of the balance spring 171 into the first water supply channel 1162, please refer to [link / reference needed]. Figure 24The first water supply channel 1162 is used to connect the port of the upper water outlet cavity 11482 to the second guide port. The second guide port is provided with a positioning guide part 1164. The positioning guide part 1164 is inclinedly connected to the inner wall of the flow channel of the first water supply channel 1162 along the central axis direction. During the assembly process, the balance spring 171 only needs to abut the end of the balance spring 171 against the positioning guide part 1164. Under the guidance of the positioning guide part 1164, the balance spring 171 will slide into the first water supply channel 1162 by itself to achieve the purpose of self-positioning, thereby improving the assembly efficiency and ease of assembly of the flow balance spring 171.

[0163] As another preferred embodiment, please refer to the following for details. Figure 17 , Figure 18 as well as Figure 19 As shown, the diversion assembly 17 also includes a diaphragm base 174, on which a base through hole 1741 is provided. The base through hole 1741 communicates with the diaphragm through hole 1724. It can be understood that when the diversion assembly 17 is not equipped with a diaphragm top cover 173, the base through hole 1741 and the diaphragm through hole 1724 constitute the aforementioned flow passage. Alternatively, when the diversion assembly 17 is equipped with the aforementioned diaphragm top cover 173, the diversion balancing membrane 172 is sandwiched between the diaphragm top cover 173 and the diaphragm base 174, and the top cover through hole 1731, the diaphragm through hole 1724, and the base through hole 1741 constitute the aforementioned flow passage. The diaphragm base 174 is positioned on the side of the diversion balancing membrane 172 facing away from the first water inlet 1144. This ensures that if the flow rate of purified water from the first water inlet 1144 suddenly decreases, and the water purifier's inlet flow rate fails to adjust accordingly, the pressure in the upper outlet chamber 11482 will rapidly increase. In this situation, the diaphragm base 174 provides strong support for the diversion balancing membrane 172. The diaphragm base 174 possesses a certain structural strength, preventing excessive deformation of the diversion balancing membrane 172 towards the return guide section 1171 due to reverse pressure. This ensures the stability and reliability of the entire diversion assembly 17, preventing blockages or other malfunctions caused by excessive deformation of the diversion balancing membrane 172. It also ensures the water purifier operates continuously and stably under different operating conditions, effectively improving its efficiency and lifespan, and providing users with a more reliable water purification experience.

[0164] It is understandable that the "pressure difference formed by the pure water inlet 1143, the first water supply port 1144, and the second water supply port 1145" mentioned above is also equivalent to the pressure difference between the diaphragm top cover 173 side and the diaphragm base 174 side, which is the pressure difference between the two sides of the diversion balance membrane 172.

[0165] Furthermore, please refer to the specific details. Figures 17 to 18As shown, the diaphragm base 174 is also provided with a base clearance hole 1742. The size of the base clearance hole 1742 is larger than the diameter of the return guide part 1171, allowing the return guide part 1171 to pass through the base clearance hole 1742 and abut against the diversion balance membrane 172. In this embodiment, the shape of the base clearance hole 1742 is not specifically limited; for example, it can be a circular hole, a square hole, or an elliptical hole. In this way, the diversion balance membrane 172 can accurately seal the guide channel 1172, thereby effectively blocking the return path of pure water. This also ensures that under normal diversion operation, the water flow can flow orderly according to the predetermined diversion channel, avoiding the unnecessary loss or backflow of pure water that interferes with the normal water output process. At the same time, the flexibility of the diversion balance membrane 172 improves the sealing performance between the diversion balance membrane 172 and the return guide part 1171.

[0166] It should be noted that, such as Figure 21 As shown, the diaphragm base 174 is provided with a base water outlet 1743 that connects to the flow regulating port 1722. That is, the base water outlet 1743 on the diaphragm base 174 is correspondingly provided and connected to the duckbill cavity 1723 of the flexible check part 1721, ensuring that pure water can pass through the base water outlet 1743 and flow into the duckbill cavity 1723. When the flow regulating port 1722 is open, pure water will be able to pass through the flow regulating port 1722 and flow into the upper water outlet cavity 11482.

[0167] As another preferred embodiment, please refer to the following for details. Figure 21 As shown, a flow guide extension 175 extends from the diaphragm top cover 173 toward the diaphragm through-hole 1724. The flow guide extension 175 is preferably integrally formed with the diaphragm top cover 173. A water passage hole 1751 is provided through the interior of the flow guide extension 175. This "through" should be understood as the water passage hole 1751 extending through both ends of the flow guide extension 175 along its extension direction. The flow guide extension 175 is inserted into the diaphragm through-hole 1724. At this time, the top cover through-hole 1731, the diaphragm through-hole 1724, the base through-hole 1741, and the water passage hole 1751 constitute the flow passage. During the flow of pure water through the water passage hole 1751, it is equivalent to pure water flowing from the lower outlet chamber 11481 sequentially through the base through-hole 1741, the diaphragm through-hole 1724, and the top cover through-hole 1731, finally flowing into the upper outlet chamber 11482.

[0168] This design not only effectively guides the flow of purified water through the water passage 1751, making the flow of purified water within the passage more orderly and smooth, reducing turbulence and energy loss, but also, the tight and orderly connection structure between the components allows for precise insertion of the flow guide extension 175 into the diaphragm passage 1724 of the flow-dividing balance membrane 172 and the base passage 1741 of the diaphragm base 174 during assembly, improving positioning accuracy and assembly efficiency.

[0169] Furthermore, please combine Figures 18 to 21 As shown, the flow guide extension 175 passes sequentially through the top cover through hole 1731, the diaphragm through hole 1724, and the base through hole 1741, extending beyond the base through hole 1741. The portion of the flow guide extension 175 extending beyond the base through hole 1741 has a protruding snap-fit ​​protrusion 1752, which snaps onto the diaphragm base 174, thus achieving a snap-fit ​​connection between the diaphragm top cover 173 and the diaphragm base 174. This ensures that the shunt balancing membrane 172 is clamped between the diaphragm top cover 173 and the diaphragm base 174, facilitating convenient and efficient assembly and disassembly, and making subsequent component replacement easier. Furthermore, the structure is simple, reducing the processing cost of each component. Alternatively, the side of the diaphragm base 174 facing away from the shunt balancing membrane 172 can be provided with a base slot, into which the snap-fit ​​protrusion 1752 snaps.

[0170] Preferably, the flow guide extension 175 is located inside the top cover through hole 1731, and a buffer gap is formed between the flow guide extension 175 and the hole wall of the top cover through hole 1731. This not only ensures that the assembly personnel can observe the diaphragm through hole 1724 of the flow balancing membrane 172 through the buffer gap during the assembly process, facilitating assembly positioning and further improving assembly efficiency. At the same time, the buffer gap serves as space for the deformation of the flow guide extension 175 during the snap-fit ​​process, thereby facilitating the snap-fit ​​protrusion 1752 to snap onto the diaphragm base 174 or to remove the snap-fit ​​protrusion 1752 from the diaphragm base 174.

[0171] It should be noted that in other embodiments, the flow guide extension 175 may also extend from the diaphragm base 174 toward the diaphragm through hole 1724. In this case, the flow guide extension 175 passes through the base through hole 1741, the diaphragm through hole 1724, and the top cover through hole 1731 in sequence and extends out of the top cover through hole 1731. The part of the flow guide extension 175 extending out of the top cover through hole 1731 is provided with a snap-fit ​​protrusion 1752, which is snapped onto the diaphragm top cover 173. This is a conventional replacement method of the above preferred embodiment.

[0172] It should also be noted that, such as Figure 21As shown, the diameter of the water passage 1751 gradually increases along the water flow direction. According to the above description, the water flow direction is from the base through-hole 1741, through the diaphragm through-hole 1724, and then through the top cover through-hole 1731. Therefore, the diameter of the water passage 1751 gradually increases along a first direction, which is from the diaphragm base 174 side along the central axis of the water passage 1751 towards the diaphragm top cover 173 side. Thus, when pure water flows in from the side with the smaller diameter and then flows out from the side with the larger diameter, the cross-sectional area of ​​the water passage 1751 gradually increases. According to the flow rate formula Q = vA (Q is the flow rate, v is the flow velocity, and A is the cross-sectional area), with the flow rate remaining essentially constant, an increase in cross-sectional area leads to a decrease in flow velocity. A lower flow velocity reduces pressure loss within the water passage 1751. Simultaneously, when pure water flows into the water passage 1751 from the side with the smaller diameter, a relatively orderly flow state can be formed. As the diameter gradually increases, the purified water has sufficient space to transition smoothly, reducing turbulence caused by sudden spatial changes and effectively preventing the formation of small air bubbles in the purified water. Furthermore, the smaller diameter side also limits the impact force of the water flow, reducing physical damage such as scratching to the water passage 1751 and the flow-dividing balancing membrane 172.

[0173] In the above description, the pressure on the side of the diversion balancing membrane 172 facing the first water inlet 1144 differs significantly from the pressure on the side of the diversion assembly 17 facing away from the first water inlet 1144. This causes the diversion balancing membrane 172 to undergo elastic deformation towards the first water inlet 1144, which in turn moves the membrane top cover 173 and / or the membrane base 174 towards the first water inlet 1144. To ensure and increase the elastic deformation of the diversion balancing membrane 172 towards the first water inlet 1144, such as... Figures 18 to 21 As shown, a deformation groove 1725 is provided on the diversion balancing membrane 172. The deformation groove 1725 is a U-shaped groove, located outside the flexible check portion 1721, and extends circumferentially along the membrane top cover 173. Understandably, the orientation of the groove opening of the deformation groove 1725 can be set and adjusted according to the structural design and design requirements. In this embodiment, the groove opening of the deformation groove 1725 is preferably oriented towards the lower outlet cavity 11481.

[0174] Thus, when the diversion balancing membrane 172 is subjected to pressure, the circumferentially extending deformation groove 1725 provides ample space for the deformation of the diversion balancing membrane 172. This not only concentrates stress in the deformation groove 1725, allowing for effective stress release and uniform deformation, but also effectively avoids the risk of rupture and fatigue damage caused by excessive stress concentration in other parts of the diversion balancing membrane 172. Simultaneously, it effectively enhances the deformation capacity of the diversion balancing membrane 172 within a limited space. When the diversion balancing membrane 172 is affected by pressure changes in the outlet chamber 1148, the deformation groove 1725 can serve as a pre-set deformation area, better guiding the diversion balancing membrane 172 to produce larger deformations. This allows the diversion balancing membrane 172 to respond sensitively to these pressure differences, achieving better pressure balance in all directions and facilitating more precise control of the diversion by the diversion assembly 17.

[0175] Further details are available according to... Figures 18 to 21 As shown, the deformation groove 1725 has a diaphragm latching portion 1726 protruding outward from the groove wall away from the flexible check portion 1721. Preferably, the diaphragm latching portion 1726 is disposed on the groove wall of the deformation groove 1725 near the groove opening, and the diaphragm latching portion 1726 is integrally formed with the flow-dividing balance membrane 172. The diaphragm latching portion 1726 extends along the groove length direction of the deformation groove 1725 and is clamped between the upper valve body shell 116 and the lower valve body shell 117, thereby realizing the purpose of detachably connecting the flow-dividing balance membrane 172 between the upper valve body shell 116 and the lower valve body shell 117, and improving the assembly efficiency of the flow divider 1.

[0176] Specifically, such as Figure 24 As shown, a diaphragm slot 1173 is provided on the lower valve body shell 117, and a diaphragm engaging portion 1726 is embedded inside the diaphragm slot 1173, making the diaphragm engaging portion 1726 more firmly connected between the upper valve body shell 116 and the lower valve body shell 117, thus improving the ability of the flow-dividing balance diaphragm 172 to be more firmly assembled on the valve body shell 11. Furthermore, the groove wall of the diaphragm slot 1173 near the flexible check portion 1721 extends towards the interior of the deformation groove 1725, meaning that the groove wall of the diaphragm slot 1173 near the flexible check portion 1721 is housed inside the deformation groove 1725, making the flow-dividing assembly 17 and the valve body shell 11 more compact, which helps to reduce the volume of the flow divider 1. It should be noted that, in addition to the diaphragm slot 1173 being provided on the lower valve body shell 117, the diaphragm slot 1173 is also provided on the upper valve body shell 116.

[0177] Preferably, such as Figure 24As shown, the upper valve body 116 is provided with a diaphragm anti-detachment groove 1165, and the diaphragm locking part 1726 is provided with a diaphragm anti-detachment body 1727 that inserts into the diaphragm anti-detachment groove 1165, which further improves the stability of the connection between the flow balancing diaphragm 172 and the valve body 11. Understandably, if the diaphragm locking groove 1173 is provided on the upper valve body 116, then the diaphragm anti-detachment groove 1165 is correspondingly provided on the lower valve body 117.

[0178] In a water purification system, when a user starts or stops the tankless water dispenser, the flow velocity of the purified water passing through the distributor 1 changes drastically, resulting in water hammer. The instantaneous pressure wave generated by water hammer may damage the distribution component 17 in the distributor 1. Based on this, the inventors also provide a preferred embodiment, please refer to [link to preferred embodiment]. Figure 17 and Figure 16 The diverter 1 also includes a water hammer absorber 18, which is located between the diverter assembly 17 and the pure water inlet 1143, and is detachably connected to the valve housing 11. Specifically, the water hammer absorber 18 is installed inside the lower outlet chamber 11481, so that the pressure wave generated by the water hammer is buffered before entering the upper outlet chamber 11482.

[0179] This configuration buffers the pressure wave before it reaches the diversion assembly 17, reducing the risk of damage to the diversion assembly 17 caused by the high pressure generated by water hammer and extending its service life. Simultaneously, the water hammer absorber 18 absorbs some of the energy, reducing vibration and noise generated by water flow impacting the valve housing 11. Furthermore, the water hammer absorber 18 ensures the stability of the diversion assembly 17 during adjustment, reduces water hammer interference in the diversion process, ensures the normal operation of the diverter 1, and improves the diversion accuracy of the diverter 1.

[0180] Preferably, please refer to the following: Figure 24 As shown, the water hammer absorber 18 is provided with a plurality of water flow buffer holes 181, which are evenly distributed. The water outlet chamber 1148 is connected to the pure water inlet 1143 through the plurality of water flow buffer holes 181. When pure water flows into the water hammer absorber 18 from the pure water inlet 1143 and passes through the water flow buffer holes 181, the water flow buffer holes 181 play a role in buffering the water flow. This is because the flow direction and speed of the pure water change when it flows through the water flow buffer holes 181. For example, when the fast-flowing pure water passes through the plurality of water flow buffer holes 181, it will be dispersed into multiple small water streams and consume some of the kinetic energy of the water flow, thereby reducing the degree of abrupt change in the water flow speed and mitigating the possibility of water hammer.

[0181] Furthermore, the presence of the water flow buffer hole 181 can also regulate the pressure changes of the water flow. According to Bernoulli's principle, when water flows through the water flow buffer hole 181, its pressure will create a certain pressure difference on both sides of the water hammer absorber 18, playing a certain regulatory role. At the same time, due to the presence of the water flow buffer hole 181, the pure water will flow to a certain extent under the action of the pressure difference. This flow can alleviate the rapid rise in pressure, making the pressure change more gradual and further reducing the water hammer phenomenon.

[0182] It should be noted that this application does not limit the number, size, and distribution of the water flow buffer holes 181, which can be set and adjusted according to the structural design and design requirements. By reasonably setting the number, size, and distribution of the water flow buffer holes 181, it is also possible to change the pulse frequency of the pure water flow. For example, when water hammer occurs, high-frequency pressure pulses will appear. By configuring the water flow buffer holes 181 in a combination of large and small holes, where the large holes allow a larger flow rate of water to pass through and the small holes impose more restrictions on the water flow, the high-frequency pressure pulses can be converted into relatively low-frequency pulses (that is, irregular pulses become more regular). The impact of low-frequency, regular pressure changes on the distributor 1 is relatively small, which also helps to mitigate the harm of water hammer.

[0183] Furthermore, please refer to the specific details. Figure 24 and Figure 25 As shown, the water hammer absorber 18 is provided with a positioning and assembly hole 182 for inserting the return guide part 1171. The diameter of the positioning and assembly hole 182 is adapted to the diameter of the return guide part 1171, so as to quickly and firmly install the return guide part 1171 on the lower valve body 117 of the valve housing 11. To ensure that the water hammer absorber 18 can be more firmly installed on the lower valve body 117 and to make the force between the water hammer absorber 18 and the lower valve body 117 more balanced, the inner wall of the outlet lower cavity 11481 is formed with an absorber boss 1174. The edge of the water hammer absorber 18 abuts against the absorber boss 1174. The structure is simple and easy to disassemble and assemble, which is beneficial to subsequent maintenance and repair.

[0184] Of course, please refer to the specific details. Figure 25 As shown, the absorber boss 1174 protrudes towards the diversion assembly 17 to form a limiting protrusion 1175, and the edge of the water hammer absorber 18 is provided with a limiting notch 183 for inserting the limiting protrusion 1175. In this way, the limiting notch 183 and the limiting protrusion 1175 cooperate to prevent the water hammer absorber 18 from deflecting around the return guide 1171, thereby guiding the flow of pure water more stably.

[0185] In other embodiments, the water hammer absorber 18 described above can also be a piston-type water hammer eliminator or a diaphragm-type water hammer eliminator. Both of these are relatively mature existing technologies in water hammer eliminators, and their structures will not be described in detail here. Alternatively, the water hammer absorber 18 described above can also be a slow-closing check valve.

[0186] As a preferred embodiment, please refer to the following for details. Figure 22 , Figure 23 and Figure 24 As shown, the diverter 1 also includes a water filter element 19. The lower valve body 117 of the valve housing 11 is provided with a water inlet channel 1176. The lower outlet chamber 11481 of the outlet chamber 1148 is connected to the pure water inlet 1143 through the water inlet channel 1176. The water filter element 19 is disposed in the water inlet channel 1176. The water filter element 19 is provided with a filter hole 191 in the extending direction of the water inlet channel 1176. A water passage gap is formed between the peripheral sidewall of the water filter element 19 and the inner sidewall of the water inlet channel 1176. A drain outlet 192 connected to the water passage gap is provided on the peripheral sidewall of the water filter element 19. The opening size of the drain outlet 192 is larger than the aperture of the filter hole 191.

[0187] With this configuration, the filter holes 191 on the water filter element 19 can perform secondary filtration in the direction of the pure water flow, preventing small particles that may appear when the water purifier filter element is nearing the end of its service life from flowing into the water outlet chamber 1148 and the tankless water dispenser. This ensures and improves the purity of the pure water supplied to the tankless water dispenser and faucet, thereby enhancing the taste and quality of drinking water.

[0188] More importantly, when purified water passes through the filter holes 191 of the filter element 19, the relatively small aperture of the filter holes 191 creates some resistance to the water flow. The presence of the drain outlet 192 helps to divert the flow. The opening of the drain outlet 192 is larger than the aperture of the filter holes 191, allowing some water to flow through the drain outlet 192 and the water passage gap, thus reducing the water flow velocity through the filter holes 191 and lowering the water resistance. Simultaneously, the presence of the drain outlet 192 and the water passage gap also helps to balance the pressure within the inlet channel 1176. Water can be redistributed between the filter holes 191 and the drain outlet 192, resulting in a more uniform pressure distribution within the entire inlet channel 1176 and reducing the water resistance of the inlet channel 1176 and the entire diverter 1.

[0189] Preferably, please refer to Figure 22 , Figure 23 and Figure 24The water filter element 19 includes a main body fastening part 193 and a main body filter part 194 fixedly connected to the main body fastening part 193. The fixed connection is preferably integrally formed for ease of manufacturing. Both the drain outlet 192 and the filter hole 191 are located on the main body filter part 194. Specifically, the main body filter part 194 has a bottom wall and a side wall extending circumferentially along the bottom wall. The bottom wall and side wall cooperate to form a filter cavity, which has a filter cavity opening opposite to the bottom wall. The filter hole 191 is located on the bottom wall, the drain outlet 192 is located on the side wall, and the main body fastening part 193 is located on the side of the side wall near the filter cavity opening, extending circumferentially along the filter cavity opening. The main body fastening part 193 is formed by a misaligned protrusion on the outer side wall of the filter part. When the filter part 19 is inserted into the water inlet channel 1176, the main body fastening part 193 can be detachably connected to the lower valve shell 117 of the valve shell 11, and the main body filter part 194 and the inner side wall of the water inlet channel 1176 automatically form a water passage gap.

[0190] It should be noted that the drain outlet 192 is a drainage group, which includes several drain holes arranged circumferentially along the filter section 194 of the main body, and the diameter of each drain hole is larger than the diameter of the filter hole 191. The drainage group can be configured as one set or multiple sets. Multiple sets of drainage groups are evenly arranged along the extension direction of the water inlet channel 1176. Or, as... Figure 23 As shown, the drain outlet 192 may also be in the form of a strip-shaped hole, and the drain outlet 192 extends along the circumferential portion of the filter section 194 of the main body. The number of drain outlets 192 may be one or more, and the multiple drain outlets 192 are arranged along the extension direction of the water inlet channel 1176, and adjacent drain outlets 192 are preferably staggered.

[0191] Preferably, such as Figure 22As shown, a filter clip 1177 is protruding from the inner wall of the water inlet channel 1176. The filter clip 1177 extends circumferentially along the water inlet channel 1176, and the main body fastening part 193 engages with the filter clip 1177. The filter clip 1177 extends along the extension direction of the water inlet channel 1176. Furthermore, the filter clip 1177 is provided with a fastening groove, and the main body fastening part 193 is provided with a fastening protrusion 195. The fastening groove and the fastening protrusion 195 are inserted and connected. In this way, the filter element 19 is effectively and stably installed and connected inside the water inlet channel 1176, and the filter element 19 will not easily shift under the long-term impact of water flow, thereby ensuring that the filter hole 191 and the drain outlet 192 can function normally and maintain the stability of the filtration function. Meanwhile, the filter clip body 1177 snaps into the filter slot, and the fastening slot is connected to the fastening protrusion 195, making the installation of the filter element 19 more convenient. When assembling the diverter 1, the worker only needs to align the filter element 19 with the water inlet channel 1176 and perform the snap-fit ​​operation to complete the installation, which also facilitates subsequent disassembly, cleaning, replacement, and maintenance. It should be noted that, in addition to the above-mentioned method where the fastening slot is set on the filter clip body 1177 and the fastening protrusion 195 is set on the main body fastening part 193, the fastening slot can also be set on the main body fastening part 193, in which case the fastening protrusion 195 is correspondingly set on the filter clip body 1177.

[0192] In a preferred embodiment, the diverter 1 further includes a water resistance element to increase the resistance to water flow. The lower valve body 117 of the valve housing 11 has a second water supply channel 1178, and the second water inlet 1145 connects to the outlet chamber 1148 through the second water supply channel 1178. The water resistance element is disposed in the second water supply channel 1178 and is detachably connected to the valve housing 11. This configuration effectively avoids pressure fluctuations caused by water flow impact. When the faucet is suddenly opened or closed, the rapid change in water flow velocity can cause water hammer, resulting in a sudden increase in pressure within the second water supply channel 1178. The resistance of the water resistance element can slow down the sudden change in water flow velocity, thereby buffering this pressure change. Simultaneously, the water resistance element can also play a role in preventing backflow. When the pressure within the second water supply channel 1178 suddenly decreases, water backflow may occur. Because the water resistance element increases the resistance to backflow, the possibility of backflow is reduced.

[0193] In this embodiment, please refer to the following for details. Figure 22 and Figure 24As shown, a water-passing support frame 1131 with a bracket outlet 1134 is provided on the lower shell 117 of the valve body. Preferably, two water-passing support frames 1131 are configured, and the two water-passing support frames 1131 are staggered. The inner wall of the water channel of the second water supply channel 1178 cooperates with the two water-passing support frames 1131 to form four bracket outlets 1134. The water-passing support frame 1131 is located inside the second water supply channel 1178. The water-passing support frame 1131 is preferably integrally formed with the lower shell 117 of the valve body, and the water resistance element abuts against and connects to the water-passing support frame 1131. Further, a bracket positioning part 1132 is provided on the side of the water-passing support frame 1131 facing the water outlet cavity 1148. The water resistance element can be provided with a water resistance socket for inserting into the bracket positioning part 1132, so that the water resistance element can be stably installed and fixed on the bracket positioning part 1132.

[0194] Preferably, please refer to the following for details. Figure 22 , Figure 24 and Figure 25 As shown, the inner wall of the second water supply channel 1178 is provided with a supporting protrusion 1133. The supporting protrusion 1133 extends along the extension direction of the second water supply channel 1178, and the water resistance component abuts against the supporting protrusion 1133, making the water resistance component more securely installed inside the second water supply channel 1178. Furthermore, the cross-sectional area of ​​the supporting protrusion 1133 gradually increases from the side near the water outlet cavity 1148 towards the side of the second water supply port 1145. In this way, during the molding process of the lower valve body shell 117, the draft angle of the supporting protrusion 1133 makes it easier to separate the mold and the lower valve body shell 117, and during the demolding process, the supporting protrusion 1133 may suffer defects such as tearing or deformation, which may affect product quality. Meanwhile, as the cross-sectional area of ​​the supporting protrusion 1133 gradually increases, it acts as a guide during the installation of the water resistance component. This allows the water resistance component to slide more easily into the correct installation position along the draft angle, facilitating installation and increasing stability. After installation, the larger cross-sectional area of ​​the supporting protrusion 1133 restricts the movement of the water resistance component in the flow channel direction. For example, when water impacts the water resistance component, it will not easily shift along the flow channel, ensuring its stable and normal function in resisting water flow. Furthermore, the supporting protrusion 1133 better guides the flow of pure water. Because the cross-sectional area of ​​the supporting protrusion 1133 gradually increases, the water flow changes direction more smoothly as it passes over it, reducing turbulence and improving the stability and uniformity of the water flow.

[0195] In a preferred embodiment, the water-blocking component includes a body with several flow-limiting water-blocking holes. Each flow-limiting water-blocking hole is connected to the outlet 1134 of the support, and the body is connected to the aforementioned support protrusion 1133. Thus, when pure water passes through these flow-limiting water-blocking holes, the resistance of the holes ensures thorough mixing of water and air, reducing the water flow rate and causing the water to flow out in a foamy manner. Furthermore, the multiple flow-limiting water-blocking holes connected to the outlet 1134 of the support allow for more even dispersion of the water flowing from the outlet, achieving water conservation while preventing splashing. In some embodiments, the water-blocking component may be a one-way valve assembly, a throttle valve, or an aerator.

[0196] The unexpected effect is that, Figure 24 As shown, when the water hammer absorber 18 is installed in the lower outlet chamber 11481, it better confines the water resistance component within the second water supply channel 1178, ensuring the stability of the water resistance component's installation. Simultaneously, since the water hammer absorber 18 is installed upstream of the water flow to the water resistance component, it can absorb and buffer the water hammer pressure wave before it reaches the component. This protects the water resistance component, preventing damage from excessive water hammer pressure and ensuring it can properly perform its functions of flow restriction and pressure regulation. It can more accurately control the water flow according to its designed flow-limiting water resistance orifice and other structures, thus providing more stable water inlet conditions for subsequent faucets or other water outlet devices, reducing the impact of water hammer on the faucet, extending its service life, and reducing the frequency of maintenance and replacement.

[0197] It should be noted that, in order to reduce the vibration of the water resistance component during the water resistance process, a bearing slot for inserting and connecting the bearing protrusion 1133 can also be provided on the peripheral side wall of the water resistance component body. In addition, the diameter of the flow-limiting water resistance hole is between 0.5-1.5mm to provide relatively stable water flow resistance, thereby avoiding the risk of blockage during long-term use.

[0198] In a preferred embodiment, the diverter 1 further includes an inlet filter element located at the raw water inlet 1141, preferably a filter screen. This effectively prevents large particles (such as sediment) from entering the inlet chamber 1147 of the tap water, achieving preliminary filtration and avoiding damage to the pressure regulating component 16 inside the diverter 1 and the risk of pressure stabilization failure. It also reduces the total amount of impurities entering the water purifier, extending the lifespan of the water purifier's filter element to some extent. In conjunction with the filter element 19 located at the pure water inlet 1143, the diverter 1 achieves dual filtration. Even though the purified water after filtration has removed most impurities, bacteria, and harmful substances, it may still be contaminated during transport, such as by residual or aging particles in the pipes. The filter element 19 further intercepts these impurities, ensuring that the purified water flowing to each water terminal is of higher quality. At the same time, the system achieves triple filtration of the water source, thus effectively ensuring good water quality and providing users with safer drinking water.

[0199] In the above description, excess purified water inside the outlet chamber 1148 can flow back to the return chamber 1146 under the regulation of the diversion component 17. The return chamber 1146 can combine the pressure-stabilized water after it has passed through the pressure regulating component 16 with the excess water flowing back from the diversion component 17, and output it to the water purifier from the raw water outlet 1142. This allows the water source to be redistributed and utilized within the water purification system, reducing water waste. However, when the amount of excess water flowing back from the outlet chamber 1148 to the return chamber 1146 is much less than the amount of pressure-stabilized water supplied from the inlet chamber 1147 to the return chamber 1146, that is, when the pressure on the side of the return chamber 1146 near the outlet chamber 1148 is less than the pressure on the side of the return chamber 1146 near the inlet chamber 1147, this can easily cause the pressure-stabilized water entering the return chamber 1146 to flow back into the outlet chamber 1148, thereby affecting the water quality of domestic water and direct drinking water.

[0200] Based on this, a preferred embodiment is also disclosed in the embodiments of this application, please refer to the following for details. Figure 3As shown, the diverter 1 also includes a unidirectional flow guide 13, which is disposed in the return chamber 1146 to prevent the pressure-stabilized water after pressure stabilization in the inlet chamber 1147 from flowing back to the outlet chamber 1148. It also collects excess water flowing back from the outlet chamber 1148 towards the return chamber 1146 and outputs it to the water purifier after stabilization. This not only prevents the pressure-stabilized water after pressure stabilization in the inlet chamber 1147 from flowing back to the outlet chamber 1148, thus avoiding the mixing of purified water and pressure-stabilized water in the outlet chamber 1148, but also ensures the quality and quantity of purified water supplied by the diverter 1. Simultaneously, it maintains the pressure in both the outlet chamber 1148 and the inlet chamber 1147, ensuring that the water flow in the outlet chamber 1148, inlet chamber 1147, and return chamber 1146 follows the designed direction and pressure conditions, achieving stability while simplifying the piping components and connections of the water purification system.

[0201] An unexpected benefit is that the unidirectional flow guide 13, when assembled in the return chamber 1146 of the valve housing 11, makes the assembly between the unidirectional flow guide 13 and the valve housing 11 more compact. In a space-constrained water purification system, this assembly method offers a higher degree of integration, saves space, effectively simplifies the piping layout of the system, and reduces the risk of leakage due to excessive pipe connections. Furthermore, it prevents damage to the distributor 1 and the water purification system caused by water hammer. Understandably, when the external water supply pipe pressure increases instantaneously, the inertia of the water flow will cause a water hammer effect, generating a high pressure wave. At this time, the unidirectional flow guide 13 can prevent this high-pressure wave from impacting the unidirectional flow guide 13 in the reverse direction, which helps extend the service life of the distributor 1 and reduces the maintenance costs of the distributor 1 and the water purification system.

[0202] As a preferred embodiment, please refer to the following for details. Figure 8 , Figure 9 and Figure 10As shown, the aforementioned unidirectional flow guide 13 includes a check valve 131 and a mixing guide 132. The check valve 131 has an inlet 1311 and an outlet 1312. The check valve 131 is used to control the flow of water from the inlet 1311 to the outlet 1312. Understandably, this water source refers to excess water flowing back from the water chamber 1148 toward the return chamber 1146. The mixing guide 132 has a flow channel 1321 inside. The mixing guide 132 has an extension 133 with an injection port 1331 protruding from the side of the check body 131. The extension 133 extends along the circumferential part of the mixing guide 132 and is located at the end of the mixing guide 132. One end of the check body 131 with an output port 1312 abuts against the extension 133 to form a mixing chamber 1332. At this time, the opening formed by the mixing guide 132, the extension 133, and the check body 131 is the injection port 1331. The injection port 1331 is connected to the mixing chamber 1332, and the output port 1312 is connected to the mixing chamber 1332. The input port 1311 is connected to the water outlet chamber 1148.

[0203] Furthermore, please refer to the specific details. Figure 6 and Figure 7 As shown, the injection port 1331 of the unidirectional flow guide 13 is positioned towards the water inlet chamber 1147, that is, the injection port 1331 is aligned with the water inlet chamber 1147, and the injection port 1331 is connected to the water inlet chamber 1147. Then, the pressure-stabilized water flowing into the return chamber 1146 will flow into the mixing chamber 1332 through the injection port 1331. The inlet port 1311 of the check body 131 is connected to the outlet chamber 1148, and the flow guide channel 1321 is connected to the raw water outlet 1142 of the lower shell 117 of the valve body. Then, excess water can only flow in from the inlet port 1311 of the check body 131 and enter the mixing chamber 1332 through the outlet port 1312. At this time, the excess water mixes with the pressure-stabilized water. After the excess water mixes with the pressure-stabilized water, it is guided by the flow guide channel 1321 to the raw water outlet 1142 and delivered to the water purifier. When the pressure in the mixing chamber 1332 is too high, that is, when the pressure on the side of the return chamber 1146 near the outlet chamber 1148 is less than the pressure on the side of the return chamber 1146 near the inlet chamber 1147, the check valve 131 will close automatically under the pressure, thereby preventing the pressure-stabilized water from flowing back to the outlet chamber 1148.

[0204] It should be further explained that, in order to ensure that the extension 133 can more smoothly abut against the end face of the check body 131 where the input port 1311 is located, please refer to the following for details. Figures 6 to 11As shown, an auxiliary support portion 135 protrudes from the side of the mixing fluid 132 facing the check body 131. The auxiliary support portion 135 is preferably distributed opposite to the extension portion 133, and the length of the auxiliary support portion 135 is equal to the length of the extension portion 133. The end of the auxiliary support portion 135 away from the mixing fluid 132 abuts against the check body 131. This arrangement ensures that both the auxiliary support portion 135 and the extension portion 133 abut against the check body 131, achieving a more balanced force distribution between the mixing fluid 132 and the check body 131. It also increases the contact area between the mixing fluid 132 and the check body 131, thereby ensuring the compactness and stability of the overall structure of the unidirectional flow guide 13.

[0205] Preferably, please refer to the following for details. Figure 6 and Figure 7 As shown, a positioning protrusion 1322 is provided on the outer side wall of the extension 133. The extension direction of the positioning protrusion 1322 is consistent with the extension direction of the guide channel 1321. The positioning protrusion 1322 is located on one side of the injection port 1331. A positioning groove 1149 is provided on the valve body 11. The positioning groove 1149 is located inside the return cavity 1146 and extends along the extension direction of the return cavity 1146. When the unidirectional flow guide 13 is assembled into the return cavity 1146, the positioning protrusion 1322 is inserted into the positioning groove 1149. Through the cooperation between the positioning protrusion 1322 and the positioning groove 1149, the injection port 1331 of the unidirectional flow guide 13 can be aligned with the water inlet cavity 1147, that is, the pressure reducing chamber outlet 1151 is aligned with the injection port 1331. The injection port 1331 completely covers the pressure reducing chamber outlet 1151, so that the pressure-stabilized water can flow more smoothly through the pressure reducing chamber outlet 1151 and the injection port 1331 and enter the mixing cavity 1332, thereby avoiding the problem of unstable water pressure caused by turbulence or eddies due to obstruction of the pressure-stabilized water.

[0206] Furthermore, during the assembly of the unidirectional flow guide 13 into the return cavity 1146, it is only necessary to align the positioning protrusion 1322 of the unidirectional flow guide 13 with and slide it into the positioning groove 1149 inside the return cavity 1146. This improves the convenience and efficiency of assembling the unidirectional flow guide 13, facilitates the subsequent disassembly and maintenance of the unidirectional flow guide 13, improves the efficiency of overhauling the distributor 1, and ensures the stability of the distributor 1 during long-term use. Since the positioning protrusion 1322 is constrained by the positioning groove 1149, it effectively prevents the unidirectional flow guide 13 from deflecting or shifting in the return cavity 1146, ensuring that the injection port 1331 of the unidirectional flow guide 13 is always aligned with the pressure reducing chamber outlet 1151 of the valve housing 11, reducing the impact and vibration of the valve housing 11 on the pressure-stabilized water, thereby reducing the noise of the distributor 1 during use.

[0207] Furthermore, please refer to the specific details. Figure 9 and Figure 10As shown, the end of the mixing fluid 132 near the extension 133 is the shoulder end of the mixing fluid 132. The shoulder end is misaligned with the extension 133 to form a shoulder portion 134. Understandably, the cross-sectional dimension of the shoulder end is larger than that of the extension 133. Therefore, the shoulder portion 134 is the part where the shoulder end connects to the extension 133 and where the cross-sectional dimension changes. Figure 7 As shown, a stepped limiting part 1152 is provided on the valve housing 11. The stepped limiting part 1152 is located inside the return cavity 1146. That is, the stepped limiting part 1152 is formed by the inner wall of the channel of the return cavity 1146 protruding towards the inside of the return cavity 1146. The shoulder end of the one-way flow guide 13 abuts against the stepped limiting part 1152 of the valve housing 11. Then, the shoulder 134 of the one-way flow guide 13 can make the mixing flow guide 132 translate in the extension direction of the positioning protrusion 1322.

[0208] In this embodiment, the mixing fluid 132 of the unidirectional flow guide 13 is inserted into the interior of the return cavity 1146 under the guidance of the positioning groove 1149 until the shoulder 134 abuts against the stepped limiting part 1152 of the contact valve housing 11, thereby restricting the movement of the mixing fluid 132 in the extension direction of the return cavity 1146 and achieving the purpose of efficient positioning.

[0209] A flow-guiding slope 136 is provided between the mixing chamber 1332 and the flow-guiding channel 1321. The flow-guiding slope 136 extends inclinedly from the mixing chamber 1332 toward the inner wall of the flow channel 1321. This design not only avoids drastic changes in a short time due to height differences during the flow of pressurized water from the mixing chamber 1332 to the flow-guiding channel 1321, thus preventing large impact forces and local turbulence instability, but also ensures that the pressurized water is transported to the water purifier from the raw water outlet 1142 at a relatively stable speed and state, sequentially through the mixing chamber 1332 and the flow-guiding channel 1321.

[0210] As a preferred embodiment, please refer to the following for details. Figure 8 and Figure 9 As shown, the check valve 131 includes a fixed housing 1313 and a valve core 1314. The valve core 1314 is movably disposed inside the fixed housing 1313. Both the inlet 1311 and the outlet 1312 are located on the fixed housing 1313. The valve core 1314 can open and close the inlet 1311 based on the pressure difference between the inlet 1311 and the outlet 1312. It can be understood that the water pressure on the inlet 1311 side is equivalent to the pressure on the side of the return chamber 1146 near the outlet chamber 1148, and the water pressure on the outlet 1312 side is equivalent to the pressure on the side of the return chamber 1146 near the inlet chamber 1147.

[0211] When the water pressure on the inlet 1311 side is greater than the water pressure on the outlet 1312 side, the valve core 1314 opens the inlet 1311, allowing excess water flowing back from the outlet chamber 1148 towards the return chamber 1146 to enter the fixed housing 1313 through the inlet 1311, and then flow through the fixed housing 1313 before entering the mixing chamber 1332 from the outlet 1312. Conversely, when the water pressure on the inlet 1311 side is less than or equal to the water pressure on the outlet 1312 side, the valve core 1314 resets and closes the inlet 1311. This prevents the pressure-stabilized water entering the mixing chamber 1332 from flowing back through the fixed housing 1313 to the outlet chamber 1148, thus achieving unidirectional flow control of excess water.

[0212] Preferably, please refer to the following for details. Figure 10 and Figure 11 As shown, the valve core 1314 includes a movable opening / closing part 13141 and an elastic reset part 13142. The elastic reset part 13142 is preferably a spring. However, it can also be a component made of an elastic material (such as rubber or silicone). The elastic reset part 13142 is preferably sleeved on the movable opening / closing part 13141, with both ends abutting against the movable opening / closing part 13141 and the fixed housing 1313, respectively. Specifically, the movable opening / closing part 13141 is provided with a spring-embedded groove. The shape and size of the spring-embedded groove are adapted to the shape and size of the elastic reset part 13142. The end of the elastic reset part 13142 is embedded inside the spring-embedded groove to prevent displacement of the elastic reset part 13142 during deformation.

[0213] Thus, when the water pressure on the inlet 1311 side is less than or equal to the water pressure on the outlet 1312 side, the sealing head 13143 of the movable opening and closing part 13141 abuts against and seals the inlet 1311, effectively preventing the pressure-stabilized water from flowing through the inlet 1311. When the water pressure on the inlet 1311 side is greater than the water pressure on the outlet 1312 side, the sealing head 13143 of the movable opening and closing part 13141 moves away from the inlet 1311 under pressure, and simultaneously squeezes the elastic reset part 13142 to generate deformation, so that the inlet 1311 and the outlet 1312 are connected. At this time, excess water can enter the outlet chamber 1148 through the inlet 1311. Understandably, when the water pressure on the inlet 1311 side is lower than the water pressure on the outlet 1312 side again, the sealing head 13143 of the movable opening and closing part 13141 moves toward the inlet 1311 side under the deformation recovery action of the elastic reset part 13142. Then the sealing head 13143 will automatically abut against the sealing inlet 1311, preventing the pressure-stabilized water from flowing through the inlet 1311 into the outlet chamber 1148.

[0214] To ensure a proper seal between the sealing head 13143 and the inlet 1311, please refer to the following: Figure 10 and Figure 11 As shown, a first sealing groove is provided on the sealing head 13143, extending circumferentially along the sealing head 13143, and a check seal ring 13144 is embedded in the first sealing groove. Under the action of the check seal ring 13144, the sealing performance between the sealing head 13143 and the inlet 1311 can be effectively improved. At the same time, it also ensures that the sealing head 13143 of the movable opening and closing part 13141 makes flexible contact with the fixed shell 1313 during the opening and closing process, reducing the wear of the check body 131 during frequent opening and closing, thereby effectively improving the service life of the check body 131 and the unidirectional fluid guide.

[0215] Preferably, please refer to the following for details. Figure 10 and Figure 11 As shown, the aforementioned fixed housing 1313 includes a valve seat housing 13131 and a retaining inner frame 13132. The valve seat housing 13131 is sleeved on the outside of the retaining inner frame 13132. The movable opening and closing part 13141 is inserted into the retaining inner frame 13132. The end of the elastic reset part 13142 abuts against the retaining inner frame 13132. The inlet 1311 is provided on the valve seat housing 13131, and the outlet 1312 is provided on the retaining inner frame 13132. When assembling the check body 131, first, the movable opening and closing part 13141 of the valve core 1314 is placed into the valve seat housing 13131. Then, the elastic reset part 13142 of the valve core 1314 is fitted onto the movable opening and closing part 13141. Finally, the retaining inner frame 13132 is embedded inside the valve seat housing 13131, with the movable opening and closing part 13141 inserted into the retaining inner frame 13132. This completes the assembly of the check body 131. At this time, the sealing head 13143 of the movable opening and closing part 13141 abuts against the inlet 1311 sealed on the valve seat housing 13131, and the elastic reset part 13142 is in a state of compression deformation. With this configuration, the valve seat housing 13131 and the retaining inner frame 13132 can be produced separately, reducing the manufacturing difficulty of the fixed housing 1313 and thus helping to reduce the manufacturing cost of the fixed housing 1313. At the same time, it facilitates the assembly of the check body 131, improves the assembly efficiency of the check body 131, and reduces the assembly cost of the check body 131.

[0216] Specifically, please see Figure 8A retaining arm 13134 is provided on the inner frame 13132. The retaining arm 13134 is located inside the output port 1312. That is, the retaining arm 13134 extends from the inner frame 13132 toward the inner side of the output port 1312. The retaining arm 13134 is provided with a guide hole 13136 for inserting into the movable opening and closing part 13141. The shape of the guide hole 13136 can be adapted to the shape of the end of the movable opening and closing part 13141. Of course, the shape of the guide hole 13136 can also be adapted to the shape of the movable opening and closing part. The shapes of the ends of 13141 are different, but it is necessary to ensure that the side wall of the end of the movable opening and closing part 13141 abuts against the inner wall of the guide hole 13136 so that the movable opening and closing part 13141 can reciprocate along the central axis of the guide hole 13136. Thus, the guide hole 13136, together with the elastic reset part 13142, can ensure that the sealing head 13143 of the movable opening and closing part 13141 is accurately reset and abuts against the input port 1311. The end of the elastic reset part 13142 abuts against the retaining arm 13134.

[0217] It should be noted here that, for details please refer to [the relevant documentation / reference]. Figures 8 to 11 As shown, a limiting boss 13135 is provided on the support arm 13134 protruding towards the movable opening and closing part 13141. The guide hole 13136 passes through the limiting boss 13135, thereby increasing the contact area between the side wall of the end of the movable opening and closing part 13141 and the inner wall of the guide hole 13136. The end of the elastic reset part 13142 is sleeved on the limiting boss 13135. In this way, the limiting boss 13135 cooperates with the spring groove provided on the movable opening and closing part 13141, which not only ensures that the elastic reset part 13142 is stably assembled in the fixed shell 1313, but also further prevents the elastic reset part 13142 from shifting during deformation.

[0218] Further details are available according to... Figure 10 As shown, in order to reduce the weight of the fixed shell 1313 and the check body 131, and also reduce the production material of the fixed shell 1313, thereby reducing the production cost of the fixed shell 1313 and the check body 131, at least one subtraction port 13133 is provided on the side wall of the inner frame 13132. The shape, size and number of the subtraction port 13133 are not limited here. The shape, size and number of the subtraction port 13133 can be set and adjusted according to the structural design and design requirements.

[0219] It should be further noted that, in order to ensure the sealing between the valve seat outer shell 13131 of the fixed shell 1313 and the inner wall of the return cavity 1146, please refer to the following for details. Figures 6 to 11As shown, a second sealing groove is provided on the valve seat housing 13131. The second sealing groove extends along the circumference of the valve seat housing 13131. An outer sealing ring 137 is embedded in the second sealing groove. Under the action of the outer sealing ring 137, the sealing performance between the fixed shell 1313 of the check body 131 and the inner wall of the return cavity 1146 can be effectively improved.

[0220] It should also be noted that, in order to securely install and fix the aforementioned unidirectional flow guide 13 in the return cavity 1146 of the valve housing 11, please refer to the following for details. Figure 6 and Figure 7 As shown, a pipe connector 14 is installed at the raw water outlet 1142. The pipe connector 14 is used to completely constrain the unidirectional flow guide 13 in the return cavity 1146, and a conduit can also be connected through the pipe connector 14.

[0221] In addition, such as Figure 3 , Figure 6 , Figure 7 As shown, at least one fastening sealing ring 15 can be configured between the pipe connector 14 and the one-way flow guide 13. On the one hand, the end of the conduit passes through the fastening sealing ring 15, which improves the sealing performance between the conduit and the return chamber 1146, effectively preventing the water pressure stabilizer from leaking out from the connection between the raw water outlet 1142 and the pipe connector 14, and also making the conduit more securely connected to the distributor 1. On the other hand, the elasticity of the fastening sealing ring 15 not only allows the pipe connector 14 and the one-way flow guide 13 to be flexibly connected, but also allows the fastening sealing ring 15 to undergo elastic deformation under the compression of the pipe connector 14 and the one-way flow guide 13 when the pipe connector 14 is assembled to the raw water outlet 1142. This deformation allows the fastening sealing ring 15 to fill the assembly gap between the pipe connector 14 and the one-way flow guide 13, and to adaptively change its shape according to the size and shape of the assembly gap. At the same time, this elastic deformation also allows the fastening sealing ring 15 to compensate for the gap changes caused by expansion, vibration and other factors during the operation of the distributor 1, thereby maintaining the stability of the assembly gap.

[0222] Of course, pipe fitting 14 can also be other quick-connect or fast-plug connectors. Similarly, pipe fitting 14 and the aforementioned fastening sealing ring 15 are also compatible with the raw water inlet 1141, pure water inlet 1143, first water supply port 1144 and second water supply port 1145. The model and size of pipe fitting 14 can be appropriately adjusted according to the raw water inlet 1141, pure water inlet 1143, first water supply port 1144 and second water supply port 1145.
