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, when the water supply exceeds the demand, the excess pure water has nowhere to overflow and is limited. If the pressure at the outlet of the pure water machine is higher than the pressure at which the pressure switch of the pure water machine is disconnected, the pure water machine will stop and then start a water pumping operation. If the pressure at the outlet of the pure water machine is lower than the pressure at which the pressure switch of the pure water machine is disconnected, the pure water machine will start working again. This will cause the pure water machine to malfunction (frequent start-up and shutdown). Summary of the Invention

[0003] This application provides a diverter and a water purification system that effectively solves the problem of frequent start-stop cycles in existing water purifiers.

[0019] The diaphragm base is provided with a base through hole, which is connected to the diaphragm through hole, and the flow hole also includes the base through hole. The diaphragm base is disposed on the side of the diversion balance membrane facing away from the first water supply port.

[0020] In one embodiment, the diaphragm top cover extends toward the diaphragm through hole with a flow guide extension, the flow guide extension having a through water passage hole, the flow guide extension being inserted into the diaphragm through hole, and the through water passage hole further including the through water passage hole.

[0021] In one embodiment, the diameter of the water passage near the diaphragm base is smaller than the diameter near the diaphragm top cover.

The upper shell of the valve body and the diversion balancing membrane cooperate to form the upper outlet chamber, and the upper shell of the valve body and the diversion balancing membrane cooperate to form the lower outlet chamber.

[0027] In one embodiment, the deformation groove has a diaphragm latching portion protruding outward from the groove wall away from the flexible check portion. The diaphragm latching portion extends along the groove length direction of the deformation groove and is sandwiched between the upper shell of the valve body and the lower shell of the valve body.

[0052] 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.

[0053] 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.

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.

[0055] 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.

[0056] 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.

[0057] To improve water utilization efficiency by simultaneously distributing purified water to both the tankless water dispenser and the faucet, the water purifier is typically equipped with a diversion valve at the outlet. Both the inlet of the tankless water dispenser and the faucet's inlet are connected to this diversion valve. Users can access drinking water at a suitable temperature, such as ice water (5℃-15℃) in hot summer weather, warm water (40℃-50℃) for making formula, or hot water (90℃-99℃) for brewing tea, by turning on the tankless water dispenser. For household water used to rinse dishes, fruits and vegetables, or clothes, users can use the faucet.

[0058] For details, please refer to the following: Figure 1 and Figure 2 As 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.

[0059] Further details are available according to... Figure 1As shown, the diverter 1 also includes a pressure regulating component 16, which is disposed within the water inlet chamber 1147 to divide the water inlet chamber 1147 into an air chamber 1153 and a liquid chamber. Specifically, a pressure reducing chamber outlet 1151 is provided on the valve housing 11, allowing the liquid chamber to connect to the return chamber 1146 through the pressure reducing chamber outlet 1151. The pressure regulating component 16 is provided with a water injection guide hole and a pressure regulating outlet connecting to the liquid chamber. The space enclosed by the pressure regulating component 16 and the upper shell 116 of the valve body forms the air chamber 1153. A water injection conduit is provided extending from the inner wall of the air chamber 1153 into the air chamber 1153. A water injection conduit is provided inside the water injection conduit, which has a water injection channel connecting to the water supply pipe. The port of the water injection channel connecting to the liquid chamber is defined as the water inlet port. The water injection conduit is inserted into the water injection guide hole, and the water injection channel of the water injection conduit connects to the liquid chamber. The pressure regulating component 16 includes a pressure regulating actuator disposed inside the liquid chamber. Based on the pressure difference between the pressure regulating outlet and the water inlet guide hole, the pressure regulating component 16 can generate relative displacement along the central axis of the water inlet guide pipe to change the throttling distance between the water inlet and the pressure regulating actuator. Thus, as the outlet pressure changes, the pressure regulating component 16 automatically makes a corresponding displacement to change the throttling distance between the water inlet and the pressure regulating actuator, thereby achieving the purpose of the distributor 1 in regulating the tap water supplied by the water supply pipeline to a stable pressure. This not only stabilizes the water pressure in the water supply pipeline but also pre-reduces the water pressure entering the water purifier, avoiding physical damage to the water purifier due to excessive water pressure. Of course, other pressure regulating components adapted to this application can also be used as replacements for the pressure regulating component 16.

[0060] Please refer to the specific details. Figure 1 As shown, a one-way flow guide 13 is installed in the return chamber 1146 to prevent the pressure-stabilized water after pressure stabilization in the liquid chamber 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 liquid chamber from flowing back into the outlet chamber 1148, ensuring the quality of domestic and drinking water, but also maintains the pressure in both the outlet chamber 1148 and the liquid chamber. This ensures that the water flow in the outlet chamber 1148, liquid chamber, and return chamber 1146 follows the designed direction and pressure conditions, thus ensuring the stability of the distributor 1 and the water purification system while simplifying the piping components and connections of the purification system.

[0061] Preferably, please refer to Figure 1The unidirectional flow guide 13 includes a check body 131 and a mixing guide 132. The check body 131 has an inlet and an outlet. The check body 131 is used to control the flow of water from the inlet to the outlet. Understandably, the water source indicates excess water flowing back from the water chamber 1148 toward the return chamber 1146. The mixing guide 132 has a flow channel inside. An extension 133 with an injection port 1331 protrudes from the side of the mixing guide 132 facing the check body 131. The extension 133 extends along the circumferential portion of the mixing guide 132 and is located at its end. One end of the check body 131 with an inlet abuts against the extension 133 to form a mixing chamber. The injection port 1331 can be aligned with and connected to the liquid chamber of the inlet chamber 1147, thus avoiding the problem of unstable water pressure caused by turbulence or eddies due to obstruction of the pressure-stabilized water. The outlet is connected to the mixing chamber, so that excess water flowing through the check body 131 will mix with the pressure-stabilized water in the mixing chamber. After mixing with the pressure-stabilized water, the excess water is guided by the flow channel to the raw water outlet 1142 and delivered to the water purifier. Of course, other one-way valves capable of mixing excess water and pressure-stabilized water and unidirectionally guiding flow can be used as alternatives to the one-way flow guide 13.

[0062] In this embodiment, please refer to the following for details. Figure 1 and Figure 2 As 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. Furthermore, the liquid chamber is connected to the raw water inlet 1141 via a water injection channel, 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, while the raw water inlet 1141 and the first water supply port 1144 are located in the upper shell 116 of the valve body.

[0063] In the above description, the diverter 1 can distribute the purified water from the water purifier. Specifically, the purified water flows through the pure water inlet 1143 and enters the outlet chamber 1148. When the tankless water dispenser connected to the first water supply port 1144 is activated, purified water can flow out from the first water supply port 1144 and be delivered to the tankless water dispenser. When the faucet connected to the second water supply port 1145 is opened, purified water can flow out from the second water supply port 1145 and be delivered to the faucet, achieving the purpose of rationally distributing purified water. Next, the specific structure involving the diversion will be explained with reference to the attached drawings.

[0064] Please refer to the following for details. Figure 1 and Figure 2 The diverter 1 also includes a diverter assembly 17, which is installed in the outlet chamber 1148 of the valve housing 11. The diverter assembly 17 is provided with a flow hole, which is used to guide the pure water flowing in from the pure water inlet 1143 through the diverter assembly 17 and into the outlet chamber 1148. Furthermore, 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, and 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.

[0065] In addition, such as Figure 10 As 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] Please refer to the specific details. Figure 2As 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.

[0074] 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.

[0075] 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.

[0076] Next, the specific structure of the above-mentioned shunt component 17 will be described in detail with reference to the accompanying drawings.

[0077] Please refer to the specific details. Figure 10As 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.

[0078] Please see below. Figures 1 to 7 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.

[0079] 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 return guide part 1171 to seal the guide channel 1172. This setting will have the following unexpected effects:

[0080] 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.

[0081] 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.

[0082] 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.

[0083] It should be further explained that, please refer to the specific details. Figure 7 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 3 to 7 The flexible check valve 1721 includes a duckbill-shaped deformation portion 17211 and a base 17212 fixedly connected to the diversion balance membrane 172. The duckbill-shaped deformation portion 17211, the base 17212, and the diversion balance membrane 172 are integrally formed to facilitate processing and manufacturing, and to ensure the integrity of the diversion balance membrane 172, so that the diversion balance membrane 172 has good comprehensive performance (such as elasticity). The duckbill-shaped deformation portion 17211 protrudes from the base 17212 toward the upper outlet cavity 11482, and in the protrusion direction, the cross-sectional area of ​​the duckbill-shaped deformation portion 17211 on the side away from the diversion balance membrane 172 is smaller than the cross-sectional area on the side closer to the diversion balance membrane 172. Preferably, the cross-sectional area of ​​the duckbill deformation portion 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 portion 17211 away from the diversion balance membrane 172, and the duckbill cavity 1723 is connected to the flow regulating port 1722.

[0084] As a preferred embodiment, please refer to the following for details. Figure 2 , Figure 3 , Figure 4 and Figure 7As 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 3 and Figure 4 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.

[0085] Further details are available according to... Figure 2 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.

[0086] Preferably, please refer to the following for details. Figure 3 , Figure 4 and Figure 7As 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.

[0087] The unexpected effect is that, Figures 3 to 7 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.

[0088] Further details are available according to... Figure 3 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 6 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:

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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 10As 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.

[0095] 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.

[0096] Preferably, please refer to the following: Figure 10 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 2 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.

[0097] 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 10The 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.

[0098] As another preferred embodiment, please refer to the following for details. Figure 3 , Figure 4 as well as Figure 5 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.

[0099] 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.

[0100] Furthermore, please refer to the specific details. Figures 1 to 4As 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.

[0101] It should be noted that, such as Figure 7 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.

[0102] As another preferred embodiment, please refer to the following for details. Figure 7 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.

[0103] 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.

[0104] Furthermore, please combine Figures 4 to 7 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.

[0105] 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.

[0106] 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.

[0107] It should also be noted that, such as Figure 7As shown, the diameter of the water passage 1751 near the diaphragm base 174 is smaller than the diameter near the diaphragm top cover 173. Preferably, the diameter of the water passage 1751 gradually increases along the water flow direction. As described above, the water flow direction is from the base through-hole 1741 through the diaphragm through-hole 1724 and 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), when the flow rate remains basically constant, an increase in the cross-sectional area will decrease the flow velocity. A lower flow velocity reduces pressure loss within the water passage 1751. Simultaneously, as purified water flows into the water passage 1751 from the smaller diameter side, a relatively orderly flow pattern is achieved. As the diameter gradually increases, the purified water has sufficient space for a smooth transition, 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 balance membrane 172.

[0108] 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 4 to 7 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.

[0109] 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.

[0110] Further details are available according to... Figures 4 to 7 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.

[0111] Specifically, such as Figure 10 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.

[0112] Preferably, such as Figure 10As 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.

[0113] 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 1 and Figure 2 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.

[0114] 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.

[0115] Preferably, please refer to the following: Figure 10 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.

[0116] 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.

[0117] 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.

[0118] Furthermore, please refer to the specific details. Figure 10 and Figure 11 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.

[0119] Of course, please refer to the specific details. Figure 11 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.

[0120] 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.

[0121] As a preferred embodiment, please refer to the following for details. Figure 8 , Figure 9 and Figure 10 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.

[0122] 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.

[0123] 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.

[0124] Preferably, please refer to Figure 8 , Figure 9 and Figure 10The 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 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 opening, extending circumferentially along the filter 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.

[0125] 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 9 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.

[0126] Preferably, such as Figure 8As 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.

[0127] 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.

[0128] In this embodiment, please refer to the following for details. Figure 8 and Figure 10As 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.

[0129] Preferably, please refer to the following for details. Figure 8 , Figure 10 and Figure 11 As shown, a supporting protrusion 1133 is provided on the inner wall of the second water supply channel 1178. The supporting protrusion 1133 extends along the extension direction of the second water supply channel 1178, and the water resistance element abuts against the supporting protrusion 1133, making the water resistance element more securely installed inside the second water supply channel 1178. Furthermore, the cross-sectional area of ​​the supporting protrusion 1133 on the side away from the second water inlet 1145 is smaller than the cross-sectional area on the side closer to the second water inlet 1145. Preferably, the cross-sectional area of ​​the supporting protrusion 1133 gradually increases from the inner wall of the second water supply channel 1178 toward the side closer to the second water inlet 1145.

[0130] Thus, during the molding process of the lower valve body shell 117, the draft angle of the supporting protrusion 1133 facilitates the separation of the mold and the lower valve body shell 117. Furthermore, during demolding, the supporting protrusion 1133 may suffer defects such as tearing or deformation, affecting product quality. Simultaneously, because the cross-sectional area of ​​the supporting protrusion 1133 gradually increases, it acts as a guide during the installation of the water resistance component. The water resistance component can more easily slide into the correct installation position along the draft angle, aiding in installation and making it more stable after installation. After installation, the larger cross-sectional area of ​​the supporting protrusion 1133 can, to some extent, restrict 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 displace along the flow channel direction, ensuring that the water resistance component stably and normally exerts its resistance to water flow. In addition, the supporting protrusion 1133 can better guide the flow of pure water. As the cross-sectional area of ​​the bearing protrusion 1133 gradually increases, the water flow will change direction more smoothly when passing through the bearing protrusion 1133, reducing the degree of turbulence in the water flow, thereby improving the stability and uniformity of the water flow.

[0131] 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.

[0132] The unexpected effect is that, Figure 10 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 also allows for more precise control of the water flow based on its designed flow-limiting water resistance orifice and other structures, providing more stable water inlet conditions for subsequent faucets or other water outlet devices. This reduces the impact of water hammer on the faucet, extending its service life and reducing the frequency of maintenance and replacement.

[0133] 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.

[0134] 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.

[0135] The above is an explanation of the diverter proposed in the embodiments of this application. Since the water purification system proposed in the embodiments of this application adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be repeated here.
