One end of the check valve with the outlet abuts against the extension to form a mixing chamber, and the injection port is aligned with and connected to the water inlet chamber.
[0013] In one embodiment, the cross-sectional area of at least a portion of the adjusting column core gradually decreases along the central axis of the adjusting column core toward the first water inlet.

[0024] Secondly, embodiments of this application provide a water purification system, which includes:
[0025] The aforementioned splitter;
[0026] Water purifier;
[0027] A tankless water dispenser is used to heat or cool water that has been purified by the water purifier.

[0030] Compared to related technologies, the technical solution of this application, through the cooperation of the return guide part of the valve shell and the adjusting column core and throttling orifice of the diversion component, not only increases the throttling gap between the adjusting column core and the throttling orifice to meet water demand when the water pumping volume of the tankless water dispenser is large, but also reduces the throttling gap as the diversion component resets when the water pumping volume of the tankless water dispenser decreases, thereby maintaining a balanced pressure difference on both sides of the diversion component until the diversion component slowly resets to the return guide part, thus solving the problem of frequent start-stop of existing water purifiers.

[0041] 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
[0042] 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.
[0043] 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.
[0044] 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.
[0045] 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.
[0046] 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.
[0047] 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. When users need 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 tap water for rinsing dishes, fruits and vegetables, or clothes, they can use the faucet.
[0048] For details, please refer to the following: Figure 1 , Figure 2 and Figure 3As 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.
[0049] Furthermore, please refer to the specific details. Figure 1 , Figure 2 and Figure 3As 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 tube to change the throttling gap 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 gap 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.
[0050] 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.
[0051] 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.
[0052] In this embodiment, please refer to the following for details. Figure 2 and Figure 3 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.
[0053] 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.
[0054] Please refer to the following for details. Figure 3 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 passage, 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.
[0055] In addition, please refer to the specific details. Figure 2 and Figure 3 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.
[0056] 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.
[0057] 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.
[0058] 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.
[0059] 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.
[0060] 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 changes caused by frequent on / off cycles). For example, without a return mechanism, a sudden change in water pressure 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.
[0061] 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.
[0062] 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.
[0063] Please refer to the specific details. Figure 2 and Figure 3As shown, the diversion assembly 17 includes an adjusting core 176, which is located inside the outlet chamber 1148. The adjusting core 176 can be integrally formed with the lower shell 117 of the valve body, or it can be detachably connected to the lower shell 117 of the valve body (e.g., threaded connection, snap-fit connection, tight fit, etc.). It extends along the extension direction of the return guide 1171, that is, the adjusting core 176 is located on one side of the return guide 1171, and the central axis of the return guide 1171 is parallel to the central axis of the adjusting core 176. The diversion assembly 17 is provided with a throttling hole 177 that has an insertion fit with the adjusting core 176. Thus, 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, the diversion component 17 can generate a relative displacement towards the first water supply port 1144, causing the diversion component 17 to separate from the return guide part 1171. Furthermore, by changing the throttling gap between the adjusting column core 176 and the throttling orifice 177 according to the pressure difference, the increase or decrease in the flow of pure water into the water outlet chamber 1148 is effectively regulated.
[0064] Understandably, when the water flow from the first water inlet 1144 is large, the pressure difference between the pure water inlet 1143, the first water inlet 1144, and the second water inlet 1145 is large. The diversion assembly 17 will move closer to the first water inlet 1144 along the central axis of the regulating column 176. This increases the throttling gap between the regulating column 176 and the throttling orifice 177, causing the regulating column 176 to disengage from the throttling orifice 177. The throttling gap will then reach its maximum, maximizing the volumetric flow rate (hereinafter referred to as flow rate) of the pure water through the throttling gap. This allows some pure water to also be channeled into the upper outlet chamber 11482 through the throttling gap. Therefore, when the water consumption of the water terminal varies significantly, the throttling gap can be used to change 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 the pure water increases as the throttling gap changes. This effectively solves the problem that the existing diverter 1 is limited by the deformation of the flow orifice, which restricts the maximum and minimum flow range that can be adjusted. This allows for a certain degree of balance in water pressure between different water terminals (such as faucets and tankless water dispensers), ensuring a more rational water flow distribution. Understandably, when the pressure difference decreases, the throttling gap will automatically decrease as the diverter assembly 17 resets. At this time, the amount of pure water flowing through the throttling gap will be reduced to a minimum, or even almost nonexistent.
[0065] It should be noted that when the throttling gap is zero, that is, when the peripheral wall of the adjusting column core 176 abuts against the inner wall of the sealing throttling orifice 177, at this time, almost no pure water flows between the adjusting column core 176 and the throttling orifice 177, and all pure water will flow into the upper water chamber 11482 through the flow passage. A flow passage is formed between the adjusting column core 176 and the throttling orifice 177. At this time, the flow divider assembly 17 abuts against the sealing return guide part 1171, and the throttling gap is reduced to a minimum. Therefore, the flow passage is the space where the throttling gap is at its minimum. A small portion of pure water can still flow into the upper water chamber 11482 through the flow passage. Thus, the flow divider assembly 17 can either eliminate the flow passage or retain the flow passage, so that the flow passage and the flow passage match.
[0066] This setting will have the following unexpected effects:
[0067] 1. The regulating core 176 is fixedly connected to the lower shell 117 of the valve body and extends along the extension direction of the return guide 1171, making the length of the regulating core 176 sufficiently long. Under the pressure difference formed by the pure water inlet 1143, the first water supply port 1144, and the second water supply port 1145, its linear displacement range is larger. For example, when the pressure difference changes significantly, the longer regulating core 176 can more accurately produce the corresponding displacement according to the magnitude of the pressure difference. This precise displacement can more finely change the throttling gap between the regulating core 176 and the throttling orifice 177, thereby achieving more precise flow regulation. Just as a longer lever can more precisely control the transmission of force, a longer regulating core 176 can more accurately adjust the water flow according to changes in water pressure, reducing the probability of limited adjustment range.
[0068] 2. The longer adjusting column 176 positioned on the lower shell 117 of the valve body also contributes to enhancing the stability of the entire distributor 1. Because it can more precisely adjust displacement and flow based on water pressure differences, the distributor 1 distributes water flow more rationally and efficiently under different water usage conditions or scenarios. For example, when the water consumption of the tankless water dispenser suddenly changes, the longer adjusting column 176 can react quickly, fully adjusting the throttling gap to prevent damage to the distributor 1 from sudden water pressure fluctuations. This is equivalent to a stabilizer maintaining the balance of the distributor 1 when water flow changes, preventing problems such as abnormal water output from the tankless water dispenser due to unstable water pressure. Furthermore, once the throttling gap is adjusted, the flow rate of purified water remains relatively stable. In long-term use, this also reduces the risk of blockage, thereby better ensuring the stability of the distributor assembly 17 and the distributor 1, and reducing manufacturing and maintenance costs.
[0069] 3. The relatively long regulating column 176 extends from the lower outlet chamber 11481 through the throttling orifice 177 and into the upper outlet chamber 11482, providing a clear guiding path for the water flow and enhancing its stability. As pure water flows from the lower outlet chamber 11481 to the upper outlet chamber 11482, the presence of the regulating column 176 directs the water flow along its periphery and through the throttling gap between the regulating column 176 and the throttling orifice 177. This is analogous to setting up a dike in a river, making the water flow direction clearer, reducing the turbulence of the water flow within the outlet chambers 1148, and improving the accuracy of guiding the water flow from the lower outlet chamber 11481 to the upper outlet chamber 11482.
[0070] When the pressure difference changes, the regulating column core 176 will be displaced, but this displacement is based on the regulation of the water flow. The regulating column core 176 can still continuously guide the water flow from the lower outlet chamber 11481 to the upper outlet chamber 11482, and adapt to the water pressure change by changing the gap between it and the throttling orifice 177, so that the water flow will not be interrupted or disordered due to water pressure fluctuations.
[0071] When water consumption is low or the flow rate is low, the water flow from the lower outlet chamber 11481 to the upper outlet chamber 11482 is small. At this time, the throttling gap between the regulating column core 176 and the throttling orifice 177 is small. The long regulating column core 176 can accurately guide these small water flows through the throttling gap, ensuring the normal operation of the distributor 1 and accurate water flow distribution under low flow conditions.
[0072] 4. The longer regulating column core 176 is located inside the water outlet cavity 1148 and fixed to the lower shell 117 of the valve body, which effectively optimizes the use of structural space. That is, it makes more reasonable and full use of the space inside the valve shell 11, and also leaves more space for other possible functional components, making the internal structure of the entire valve shell 11 more regular.
[0073] It should be noted that the throttling area at its maximum is between 3.3 and 3.7 square millimeters. When the tankless water dispenser requires a large flow of purified water, this area range ensures sufficient purified water to flow quickly into the upper outlet chamber 11482, meeting the water demand of the tankless water dispenser without restricting water supply due to an excessively small throttling gap. Simultaneously, it also helps maintain a reasonable pressure distribution within the outlet chamber 1148. When purified water passes through this throttling gap, a certain pressure drop will occur according to fluid mechanics principles. This pressure drop can balance the pressure difference between the purified water inlet 1143, the first water supply port 1144, and the second water supply port 1145. For example, when the tankless water dispenser is in use, a larger throttling gap area allows sufficient water flow into the upper outlet chamber 11482 while effectively balancing the pressure on both sides of the diverter assembly 17. This prevents an excessive pressure difference between the lower outlet chamber 11481 and the upper outlet chamber 11482 due to a smaller throttling gap area, which could affect the stability of the diverter 1 and the normal operation of the tankless water dispenser. Furthermore, when water usage changes, the diverter 1 can flexibly adjust the actual throttling area within this range in conjunction with the adjusting column core 176, avoiding sudden changes in water flow or pressure fluctuations caused by an unsuitable throttling gap area. For example, when the water consumption of the tankless water dispenser suddenly increases or decreases, the diverter 1 can quickly adjust within this range to maintain a stable water supply, reduce the impact on the tankless water dispenser, and extend the service life of both the diverter 1 and the tankless water dispenser. The preferred throttling area for maximizing the throttling gap is 3.5 square millimeters.
[0074] When the throttling area exceeds 3.7 square millimeters at its maximum, the throttling area is large, which reduces the pressure difference on both sides of the diversion component 17. When the tankless water dispenser uses boiling water (i.e., when the tankless water dispenser needs a smaller flow rate of purified water), the guide channel 1172 controlled by the diversion component 17 may not be able to open, leading to frequent start-stop cycles of the water purifier.
[0075] When the throttling area is less than 3.3 square millimeters when the throttling gap reaches its maximum state, the throttling area is small. This means that when the tankless water dispenser takes in room temperature water (that is, when the tankless water dispenser needs a large flow of pure water), the distributor 1 may not be able to handle the overflow in time, causing the pressure at the pure water outlet of the water purifier to rise and exceed the start / stop value of the high-pressure switch of the water purifier, resulting in frequent start-ups.
[0076] Preferably, the throttling area of the flow gap formed between the adjusting column core 176 and the throttling orifice 177 is between 0.9 and 1.1 square millimeters. That is, when the flow splitting component 17 abuts against the return guide part 1171, the throttling area of the throttling gap in the minimum state is between 0.9 and 1.1 square millimeters, and the throttling area of the throttling gap in the minimum state is preferably 1 square millimeter.
[0077] This design not only ensures a stable water supply for small flow rates—for example, when the water purifier is operating at low flow rates or when a tankless water dispenser requires a smaller flow of purified water—this throttling area provides excellent adjustment precision, finely distributing the purified water flow. Simultaneously, it helps maintain stable pressure within the outlet chamber 1148. According to fluid mechanics principles, the throttling area within this range generates resistance as purified water passes through, resulting in relatively gentle pressure changes within the outlet chamber 1148 and effectively preventing backflow of purified water to a certain extent. Because the throttling area of the throttling gap is small, purified water is less likely to flow backward within the normal pressure difference range, ensuring the unidirectional flow of water within the distributor 1, improving the reliability of the distributor 1, and ensuring a stable water supply when water consumption is relatively low. However, when the throttling gap is at its minimum, the throttling area is less than 0.9 square millimeters, which can lead to a small throttling area, making it difficult to mold the distributor component 17. When the throttling area is greater than 1.1 square millimeters when the throttling gap is at its minimum, this can easily lead to a large throttling area, which will increase the minimum flow rate required to ensure that the water purifier does not start and stop frequently when taking water from the tankless water dispenser.
[0078] It should also be noted that, for details, please refer to [the relevant documentation / reference]. Figure 2 and Figure 3 As shown, the cross-sectional area of the adjusting column 176 at least partially near the first water inlet 1144 is smaller than its cross-sectional area away from the first water inlet 1144. Preferably, the cross-sectional area of the adjusting column 176 at least partially gradually decreases along the central axis of the adjusting column 176 toward the first water inlet 1144. Here, the cross-section is the section of the adjusting column 176 perpendicular to its central axis.
[0079] On the one hand, this design allows the diverter assembly 17 to achieve gradual flow regulation under different displacement conditions. When the regulating column 176 moves towards the first water supply port 1144 according to the pressure difference, the change in the cross-sectional area of the channel formed between the regulating column 176 and the throttling orifice 177 is not sudden, but a gradual process, thus avoiding the impact of sudden flow changes on the system. On the other hand, this gradual cross-sectional area design can effectively expand the range of flow regulation. When the regulating column 176 is displaced significantly, the smaller cross-sectional area portion engages with the throttling orifice 177, allowing a larger flow rate to pass through; when the displacement is small, the larger cross-sectional area portion engages with the throttling orifice 177, limiting the flow rate. This allows the diverter 1 to better adapt to a wider range of water demand, satisfying both small-flow, fine-tuned water supply and large-flow, rapid water supply needs.
[0080] Furthermore, during the flow of pure water, the gradual change in the cross-sectional area of the regulating column 176 can buffer changes in water pressure. When water flows through the section with a gradually decreasing cross-sectional area, according to Bernoulli's principle, the water velocity gradually increases, while the water pressure gradually decreases. This gradual change in water pressure can prevent sudden changes in water pressure from damaging the system. Moreover, between the lower outlet chamber 11481 and the upper outlet chamber 11482, the gradual change in the cross-sectional area of the regulating column 176 helps balance the pressure difference between the two chambers. Since the gradual change in cross-sectional area can regulate water velocity and water pressure, when the pressure difference between the two chambers changes, by adjusting the displacement of the column 176 and using its gradually changing cross-sectional area to guide the water flow, the pressure difference between the two chambers can be gradually balanced. This is crucial for stable water flow distribution and the normal operation of the distributor 1, and also ensures that all water-using terminals receive a stable water supply pressure.
[0081] Next, the specific structure of the above-mentioned shunt component 17 will be described in detail with reference to the accompanying drawings.
[0082] Please refer to the specific details. Figure 3 , Figure 4 and Figure 5 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.
[0083] The diversion balancing membrane 172 is made of an elastic material (such as silicone or rubber) and has diaphragm through-holes 1724. These through-holes are also capable of elastic expansion and contraction. Furthermore, the diversion balancing membrane 172 also has diaphragm adjustment holes 1728, which serve as the throttling orifice 177. When the water consumption and pressure difference of the tankless water dispenser are low, and the throttling gap is small or at its minimum, only a small amount of pure water flows through the through-holes and / or the flow gap into the upper water chamber 11482. In this case, the flow gap plays a role in finely regulating the flow rate, ensuring that the diverter 1 can still stably distribute a small amount of pure water even with low flow demand. When the water consumption and pressure difference of the tankless water dispenser increase, the throttling gap between the regulating column core 176 and the throttling orifice 177 will increase. At this point, most of the purified water is allowed to flow into the upper outlet chamber 11482 through the enlarged throttling gap. This allows for precise adjustment of the flow rate through the distributor 1 according to different operating conditions (such as different water usage rates in tankless water dispensers), effectively reducing the probability of frequent start-ups and shutdowns of the water purifier. Simultaneously, since the throttling gap also serves as an auxiliary water flow channel, it can balance water pressure under different water usage scenarios to a certain extent, ensuring a more rational water flow distribution. Of course, the synergistic effect of the flow-through holes on the diversion balance membrane 172 and the throttling gap better maintains the pressure balance on both sides of the diversion assembly 17.
[0084] 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:
[0085] 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.
[0086] 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.
[0087] 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 pressure balance inside 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, and when the water consumption of the tankless water dispenser suddenly decreases, both can promptly reset the diversion balance membrane 172, reducing the flow rate of purified water, thereby optimizing the dynamic response capability of the diversion process.
[0088] As a preferred embodiment, please refer to the following for details. Figure 3 , Figure 4 and Figure 5As shown, the aforementioned diversion assembly 17 also includes a diaphragm top cover 173. The diaphragm top cover 173 has a top cover through hole that connects to the diaphragm through hole 1724. In this case, the top cover through hole 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. Further, the diaphragm top cover 173 also has a top cover adjustment hole 1737 that connects to the diaphragm adjustment hole 1728. Thus, the top cover adjustment hole 1737 and the diaphragm adjustment hole 1728 constitute the aforementioned throttling hole 177. One end of the balance spring 171 abuts against the inner wall of the outlet upper 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 possesses 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 cavity wall. For example, when the flow rate of pure water changes or the internal pressure of the outlet upper 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.
[0089] Furthermore, please refer to the specific details. Figure 3 , Figure 4 and Figure 5 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.
[0090] Preferably, please refer to the following for details. Figure 3 , Figure 4 and Figure 5As 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.
[0091] 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.
[0092] Considering that when the stop and limit part 1733 abuts against the inner wall of the upper water outlet chamber 11482, the water output from the first water supply port 1144 is relatively large, meaning the purified water demand of the tankless water dispenser is relatively high. To further ensure the supply of purified water, please refer to [the relevant documentation / reference]. Figure 4 and Figure 5 The stop limiting part 1733 is provided with a water passage opening 1736. That is, each stop part of the stop limiting part 1733 is provided with a water passage opening 1736 at the end near the first water supply port 1144. In this embodiment, the shape and size of the water passage opening 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 opening 1736, thereby ensuring that sufficient pure water flows to the first water supply port 1144 and is supplied to the tankless pipeline machine.
[0093] Meanwhile, under the action of the water passage opening 1736, when the stop limiting part 1733 abuts against the inner wall of the water outlet upper cavity 11482, it can also maintain the flow of pure water through the water passage opening 1736 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 limiting 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.
[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 1 As 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 for details. Figure 1 , Figure 2 and Figure 3 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 2As 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 combine... Figure 1 , Figure 2 and Figure 3 As shown, the port of the first water supply channel 1162 used to connect to the upper water outlet cavity 11482 is the second flow guide. The second flow guide is provided with a positioning guide 1164. The positioning guide 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 against the positioning guide 1164. Under the guidance of the positioning guide 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 5As 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, the diaphragm through hole 1724, and the base through hole 1741 together 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 should be noted that, for details, please refer to [the relevant documentation / reference]. Figure 3 , Figure 4 and Figure 5 As shown, the diaphragm base 174 is also provided with a base adjustment hole 1744, which connects to the diaphragm adjustment hole 1728. Understandably, when the diversion assembly 1717 is not equipped with the diaphragm top cover 173, the base adjustment hole 1744 and the diaphragm adjustment hole 1728 constitute the aforementioned throttling orifice 177. Alternatively, when the diversion assembly 1717 is equipped with the aforementioned diaphragm top cover 173, the top cover adjustment hole 1737, the base adjustment hole 1744, and the diaphragm adjustment hole 1728 together constitute the aforementioned throttling orifice.
[0100] 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.
[0101] Furthermore, please refer to the specific details. Figure 3 , Figure 4 and Figure 5As 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.
[0102] As another preferred embodiment, please refer to the following for details. Figure 4 and Figure 5 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, the diaphragm through-hole 1724, the base through-hole 1741, and the water passage hole 1751 constitute the flow passage. During the process of pure water flowing 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, 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 Figure 4 and Figure 5As shown, the flow guide extension 175 passes sequentially through the top cover through hole, 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, a base slot can be provided on the side of the diaphragm base 174 facing away from the shunt balancing membrane 172, with the snap-fit protrusion 1752 snapping into the base slot.
[0105] Preferably, the flow guide extension 175 is located inside the through hole of the top cover, and a buffer gap is formed between the flow guide extension 175 and the hole wall of the top cover through hole. 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 in sequence and extends out of the top cover through hole. The portion of the flow guide extension 175 extending out of the top cover through hole is provided with a snap-fit protrusion 1752, which snaps onto the diaphragm top cover 173. This is a conventional replacement method of the above preferred embodiment.
[0107] It should also be noted that, for details, please refer to [the relevant documentation / reference]. Figure 4 and Figure 5As 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. 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 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 cross-sectional area will decrease the flow velocity. A lower flow velocity can reduce the pressure loss of water within the water passage 1751. Meanwhile, as purified water flows from the smaller diameter side into the water passage 1751, a relatively orderly flow pattern is formed. 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... Figure 4 and Figure 5 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 membrane adjustment hole 1728, 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] Furthermore, please refer to the specific details. Figure 3 , Figure 4 and Figure 5 As shown, a diaphragm latching portion 1726 is formed on the outer side of the groove wall of the deformation groove 1725 away from the diaphragm adjustment hole 1728. 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 diaphragm 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 diaphragm 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 Figures 2 to 5 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 throttling orifice 177 extends towards the interior of the deformation groove 1725, meaning that the groove wall of the diaphragm slot 1173 near the throttling orifice 177 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 Figures 2 to 5As 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 3 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. Furthermore, the water hammer absorber 18 also has an absorber adjustment hole 184, and an adjustment core 176 is inserted into the absorber adjustment hole 184, and the adjustment core 176 can pass through the absorber adjustment hole 184, so that the adjustment core 176 can extend to the throttling orifice 177 of the diverter assembly 17 and engage with the throttling orifice 177.
[0114] It should be noted that the diameter of the absorption element adjustment hole 184 is preferably larger than the diameter of the adjustment column core 176, so that a gap is formed between the absorption element adjustment hole 184 and the adjustment column core 176, so as to facilitate the insertion and assembly between the adjustment column core 176 and the water hammer absorption element 18, and also to facilitate the smooth and stable flow of water through the gap between the absorption element adjustment hole 184 and the adjustment column core 176.
[0115] 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.
[0116] Preferably, please refer to the following for details. Figure 3 and Figure 6As 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.
[0117] 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.
[0118] 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.
[0119] Furthermore, please refer to the specific details. Figure 3 , Figure 6 and Figure 7As 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.
[0120] Of course, please refer to the specific details. Figure 3 , Figure 6 and Figure 7 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.
[0121] 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.
[0122] 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.
