[0049] To make the purpose, technical solutions and advantages of the present application more clear, the following will further describe the embodiments of the present application in combination with the drawings.

[0050] The following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all the embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0051] In the description of the present application, it is understood that the terms "first", "second" and the like are used only for descriptive purposes, and cannot be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood in specific cases. In addition, in the description of the present application, "multiple" refers to two or more, unless otherwise specified. The association between the associated objects is described, which means that there can be three relationships, for example, A and / or B, which can represent the existence of A alone, the existence of A and B, and the existence of B alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0052] 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 the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0053] One aspect of the present application proposes a pure drinking system, which comprises a water purifier, a water tankless pipeline machine and a faucet. The water purifier is used to deeply filter and purify the water source provided by the water supply pipeline, so that the water quality of the water source meets the standard of safe drinking or meets the specific use requirements. The water tankless pipeline machine is used to instantaneously heat or cool the purified water source, so that the user can accurately obtain drinking water and meet the user's different drinking water temperature requirements. It should be noted that the water purifier, the water tankless pipeline machine and the faucet all belong to the relatively mature existing technology in the art, and the present application does not make significant improvements to the water purifier, the water tankless pipeline machine and the faucet. Therefore, the structure of the water purifier, the water tankless pipeline machine and the faucet is not described in detail, and the type and model of the water purifier and the water tankless pipeline machine are not limited.

[0054] Considering that the purified water source is simultaneously distributed to the water tankless pipeline machine and the faucet, the water utilization efficiency is improved, and the back end of the water outlet of the water purifier is usually configured with a shunt valve. The water inlet end of the water tankless pipeline machine and the water inlet of the faucet are both in communication with the shunt valve. When the user needs to take temperature-specific direct drinking water, such as drinking 5℃-15℃ ice water in hot summer, or taking 40℃-50℃ warm water to wash milk powder, or taking 90℃-99℃ hot water to make tea, etc., the user can open the water tankless pipeline machine to take. When the user needs to take domestic water to wash tableware or wash vegetables and fruits or wash clothes, the user can open the faucet to take.

[0055] Specifically, please refer to Figure 1 , Figure 2 and Figure 3As shown, the flow divider 1 comprises a valve shell 11, which comprises a valve upper shell 116 and a valve lower shell 117 connected with each other, where the connection between the valve upper shell 116 and the valve lower shell 117 is understood as detachable connection, such as bolt connection, clamping connection, etc., so as to facilitate the production of the valve upper shell 116 and the valve lower shell 117, and effectively improve the assembly efficiency and reduce the assembly difficulty. In the embodiment, the valve upper shell 116 and the valve lower shell 117 are configured to form a water inlet cavity 1147, a backflow cavity 1146 and a water outlet cavity 1148, the water outlet cavity 1148 is in communication with the water inlet cavity 1147 through the backflow cavity 1146, the water inlet cavity 1147 and the water outlet cavity 1148 are preferably located at the top side of the backflow cavity 1146, and the valve upper shell 116 is an integrally formed component, and / or the valve lower shell 117 is an integrally formed component, so that the valve shell 11 assembled by the valve upper shell 116 and the valve lower shell 117 is more stable and has higher structural strength. In this way, when subjected to high-pressure fluid, the pressure can be evenly distributed in each part of the valve shell 11, effectively preventing the valve shell 11 from being broken. When subjected to external impact, it can better resist deformation, and compared with the combination of independent pressure reducing valve and flow divider, such flow divider 1 is less likely to loosen and separate, reducing the risk of leakage of the flow divider 1, improving the sealing performance of the flow divider 1, thereby ensuring that the sealing performance of the water purification system is more stable during long-term use, and simplifying the number of pipeline elements (such as valves, conduits, etc.) and pipeline connections of the water purification system, thereby facilitating the installation difficulty and subsequent maintenance difficulty of the water purification system. At the same time, the integrally formed technology can realize the manufacturing of the valve body through precise mold or machining process, and better control the dimensional accuracy and shape accuracy of the valve shell 11.

[0056] Further, please refer to Figure 1 , Figure 2 and Figure 3As shown, the flow divider 1 further comprises a pressure regulating assembly 16 arranged in the water inlet cavity 1147 to divide the water inlet cavity 1147 into an air cavity 1153 and a liquid cavity. Specifically, a pressure relief cavity discharge port 1151 is arranged on the valve housing 11, so that the liquid cavity can communicate with the backflow cavity 1146 through the pressure relief cavity discharge port 1151. The pressure regulating assembly 16 is provided with a water injection guide hole and a pressure regulating water outlet communicating with the liquid cavity. The space surrounded by the pressure regulating assembly 16 and the valve body upper shell 116 forms the air cavity 1153, and the inner wall of the chamber of the air cavity 1153 extends towards the inside of the air cavity 1153 and is provided with a water injection guide pipe portion, the inside of the water injection guide pipe portion is provided with a water injection flow channel communicating with the water supply pipeline, and the port of the water injection flow channel for communicating with the liquid cavity is defined as a water passage port. The water injection guide pipe portion is inserted into the water injection guide hole, and the water injection flow channel of the water injection guide pipe portion communicates with the liquid cavity. Since the pressure regulating assembly 16 includes a pressure regulating execution end arranged inside the liquid cavity, when a pressure difference is formed between the pressure regulating water outlet and the water injection guide hole, the pressure regulating assembly 16 can produce relative displacement along the central axis of the water injection guide pipe portion to change the throttling gap between the water passage port and the pressure regulating execution end. In this way, as the outlet pressure changes, the pressure regulating assembly 16 automatically makes corresponding displacement to change the throttling gap between the water passage port and the pressure regulating execution end, thereby achieving the purpose of the flow divider 1 regulating the tap water supplied by the water supply pipeline into stable pressure water. This not only stabilizes the water pressure in the water supply pipeline and reduces the water pressure entering the water purifier in advance, but also avoids physical damage to the water purifier caused by excessive water pressure. Of course, other pressure regulating components suitable for the present application can also be used as an alternative to the pressure regulating assembly 16.

[0057] Specifically, according to Figure 1 As shown, the backflow cavity 1146 is provided with a one-way flow guide 13 to prevent the stable pressure water flowing through the liquid cavity from flowing back to the water outlet cavity 1148, and the excess water flowing back to the backflow cavity 1146 from the water outlet cavity 1148 is combined with the stable pressure water and then output to the water purifier. This not only prevents the stable pressure water after the liquid cavity from flowing back to the water outlet cavity 1148 to ensure the water quality of domestic water and direct drinking water. At the same time, it also maintains the pressure of the water outlet cavity 1148 and the liquid cavity, so that the water flow in the water outlet cavity 1148, the liquid cavity and the backflow cavity 1146 can flow in the designed direction and pressure condition, thereby ensuring the stability of the flow divider 1 and the water purification system while simplifying the pipe elements and connections of the water purification system.

[0058] Preferably, referring to Figure 1The one-way flow guide 13 includes a check body 131 and a mixed flow guide 132. The check body 131 has an input port and an output port, and is used to control the flow of the water source from the input port to the output port. It can be understood that the water source refers to the excess water flowing back to the backflow cavity 1146 from the water cavity 1148. The mixed flow guide 132 is internally provided with a flow guide channel. The mixed flow guide 132 protrudes towards one side of the check body 131 and is provided with an extension 133 having a liquid injection port 1331. The extension 133 extends along the circumferential portion of the mixed flow guide 132 and is arranged at the end of the mixed flow guide 132. One end of the check body 131 abuts against the extension 133 to form a mixing cavity. The liquid injection port 1331 can be aligned with the water inlet cavity 1147 and communicate with the liquid cavity of the water inlet cavity 1147, thereby avoiding the problem of unstable water pressure caused by the disturbance or vortex of the stable water blocked by the excess water. The output port communicates with the mixing cavity, so that the excess water will mix with the stable water in the mixing cavity after flowing through the check body 131. The excess water mixed with the stable water is guided by the flow guide channel to the raw water outlet 1142 and delivered to the water purifier. Of course, other one-way valves that can mix excess water and stable water and guide the flow in one direction can be used as an alternative to the one-way flow guide 13.

[0059] In this embodiment, please refer to Figure 2 and Figure 3 The flow divider 1 is provided 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 the water supply pipeline to introduce tap water into the water inlet cavity 1147 of the valve shell 11. The raw water outlet 1142 is used to communicate with the water purifier to deliver the stable water treated by the water purifier. The pure water inlet 1143 is used to communicate with the water purifier to introduce the purified water purified by the water purifier. The first water supply port 1144 is used to communicate with the water tankless pipeline machine to deliver the purified water to the water tankless pipeline machine. The second water supply port 1145 is used to communicate with the faucet to deliver the purified water to the faucet. Further, the liquid cavity communicates with the raw water inlet 1141 through the water injection channel. The raw water outlet 1142 communicates with the backflow cavity 1146. The pure water inlet 1143, the first water supply port 1144 and the second water supply port 1145 all communicate with the water outlet cavity 1148. Preferably, the raw water outlet 1142, the pure water inlet 1143 and the second water supply port 1145 are arranged on the valve body lower shell 117. The raw water inlet 1141 and the first water supply port 1144 are arranged on the valve body upper shell 116.

[0060] In the above, the shunt 1 can distribute the purified water purified by the water purifier, that is, the purified water flows through the pure water inlet 1143 and enters the water outlet cavity 1148, when the water tankless pipeline machine connected with the first water outlet 1144 is used, the purified water can flow out from the first water outlet 1144 and be transported to the water tankless pipeline machine, when the faucet connected with the second water outlet 1145 is opened, the purified water can flow out from the second water outlet 1145 and be transported to the faucet, to achieve the purpose of reasonable distribution of purified water. Next, the specific structure related to shunting will be described in combination with the drawings.

[0061] Specifically, please refer to Figure 3 The shunt 1 further comprises a shunt assembly 17 installed in the water outlet cavity 1148 of the valve shell 11, wherein the shunt assembly 17 is provided with a flow hole for guiding the purified water flowing from the pure water inlet 1143 to pass through the shunt assembly 17 and enter the water outlet cavity 1148. Further, the shunt assembly 17 divides the water outlet cavity 1148 into a water outlet lower cavity 11481 and a water outlet upper cavity 11482, the above-mentioned pure water inlet 1143 and the second water outlet 1145 are both communicated with the water outlet lower cavity 11481, the water outlet upper cavity 11482 is communicated with the first water outlet 1144, and the water outlet upper cavity 11482 is communicated with the water outlet lower cavity 11481 through the flow hole. At this time, the purified water flowing from the pure water inlet 1143 into the water outlet lower cavity 11481 for buffering and storage, and a part of it will flow to the water outlet upper cavity 11482 through the flow hole, and finally flow out from the first water outlet 1144.

[0062] In addition, please refer to Figure 2 and Figure 3 It is shown that the valve shell 11 has a backflow guide part 1171 located inside the water outlet cavity 1148, and the inside of the backflow guide part 1171 is provided with a guide flow channel 1172 communicated with the backflow cavity 1146. Specifically, the backflow guide part 1171 is arranged on the valve body lower shell 117, and the backflow guide part 1171 extends towards the inside of the water outlet cavity 1148, wherein the guide flow channel 1172 extends in the port of the water outlet lower cavity 11481 to communicate with the water outlet lower cavity 11481. The shunt assembly 17 can abut against the backflow guide part 1171, and according to the pressure difference formed by the pure water inlet 1143, the first water outlet 1144 and the second water outlet 1145, the shunt assembly 17 can produce relative displacement towards the first water outlet 1144 side, so that the shunt assembly 17 is separated from the backflow guide part 1171, then the excessive purified water can flow into the backflow cavity 1146 from the guide flow channel 1172, forming the above-mentioned excess water.

[0063] Thus, when the faucet is used alone, the purified water will flow into the water outlet lower cavity 11481 from the purified water inlet 1143, and then directly flow out from the second water supply port 1145, at this time the shunt assembly 17 abuts and fits on the backflow guide part 1171 to seal the guide flow channel 1172, so that the purified water will not flow back to the guide flow channel 1172.

[0064] When the tankless pipeline machine is used alone, the purified water flows into the water outlet lower cavity 11481 from the purified water inlet 1143, and then flows through the flow hole into the water outlet upper cavity 11482, and finally flows out from the first water supply port 1144 to the tankless pipeline machine, at this time the pressure on the side of the shunt assembly 17 close to the first water supply port 1144 is less than the pressure on the side of the shunt 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 shunt assembly 17 can produce relative displacement towards the side of the first water supply port 1144, so that the shunt assembly 17 is separated from the backflow guide part 1171, and the excess purified water flows back to the guide flow channel 1172. It can be understood that the amount of water flowing out of the first water supply port 1144 is determined by the water pump and negative pressure valve of the tankless pipeline machine.

[0065] When the tankless pipeline machine is turned off, the shunt assembly 17 will reset towards the side of the backflow guide part 1171, so that the shunt assembly 17 abuts on the backflow guide part 1171 again to seal the guide flow channel 1172 again. Therefore, the shunt 1 can flexibly meet the water flow distribution requirements when the tankless pipeline machine is used alone, so that the purified water can meet the water demand of the tankless pipeline machine while reasonably handling the excess water, so as to avoid waste of water resources and risk of damage to the tankless pipeline machine due to excessive water pressure.

[0066] When the tankless pipeline machine and the faucet are used at the same time, the purified water flows into the water outlet lower cavity 11481 from the purified water inlet 1143, and then a part of the purified water flows out from the second water supply port 1145 to the faucet, and another part of the purified water flows into the water outlet upper cavity 11482 through the flow hole and then flows out from the first water supply port 1144 to the tankless pipeline machine. Due to the decrease of the water pressure on the side of the second water supply port 1145, the pressure on the side of the shunt assembly 17 close to the first water supply port 1144 is not much different from the pressure on the side of the shunt assembly 17 away from the first water supply port 1144, at this time the shunt assembly 17 abuts and fits on the backflow guide part 1171, so that the excess purified water will hardly flow to the guide flow channel 1172. In this way, the tankless pipeline machine and the faucet can both be used normally, and the stable operation of the entire purified drinking system is ensured.

[0067] Therefore, because the excess purified water can flow back only when the tankless pipeline machine is activated, the water purifier can avoid frequent adjustment of its working state due to sudden changes in water consumption of the tankless pipeline machine (e.g., changes in water pressure caused by frequent opening and closing of the tankless pipeline machine). For example, without the backflow mechanism, when the tankless pipeline machine is suddenly closed, the instantaneous change in water pressure can impact the internal structure and working pressure of the water purifier. With the backflow mechanism, the water pressure change can be buffered to some extent, and the pressure on the water purifier caused by frequent start-stop can be reduced. In the case of simultaneous water use, the relatively stable water flow distribution state is maintained by the action of the flow distribution assembly 17. Without the flow distribution assembly 17, if the faucet and the tankless pipeline machine are used simultaneously, a sudden change in water consumption of one (e.g., sudden closing of the faucet) can cause a large fluctuation in the internal water pressure of the water purifier, resulting in frequent adjustment of the working state of the water purifier. The flow distribution assembly 17 can maintain a relatively stable water pressure and water flow distribution, reducing the situation of frequent start-stop of the water purifier caused by changes in external water use.

[0068] In related technologies, the overflow holes can elastically expand and contract, and the flow of purified water through the overflow holes is adjusted by the slight deformation of the overflow holes. That is, when the water consumption of the tankless pipeline machine increases, the overflow holes expand as the pressure difference between the two sides of the flow distribution assembly 17 increases, and the flow of purified water increases. When the water consumption of the tankless pipeline machine decreases, the overflow holes contract under the action of their own elastic force, and the flow of purified water decreases, thereby automatically maintaining the pressure difference between the two sides of the flow distribution assembly 17 and delaying the resetting of the flow distribution assembly 17. However, because the deformation amount of the overflow holes is limited, the maximum and minimum flow range that can be adjusted by the overflow holes is also greatly limited. For example, when the water consumption of the water use terminal changes in a large range, due to the size and deformation amount of the overflow holes, the overflow holes with a small deformation amount cannot meet the actual flow adjustment requirements.

[0069] Therefore, based on this, the embodiments of the present application provide a flow distribution assembly 17, which aims to solve the problem that the flow distributor 1 in related technologies is limited by the deformation amount of the overflow holes, and the maximum and minimum flow range that can be adjusted is limited.

[0070] For details, please refer to Figure 2 and Figure 3As shown, the shunt assembly 17 includes an adjusting stem 176 arranged inside the water outlet cavity 1148. The adjusting stem 176 is optionally integrally formed with the valve lower shell 117, or is optionally detachably connected with the valve lower shell 117 (e.g., threaded connection, clamping connection, over-tight fit, etc.), and is arranged along the extension direction of the backflow guide portion 1171, i.e., the adjusting stem 176 is located at one side of the backflow guide portion 1171, and the central axis of the backflow guide portion 1171 is parallel to the central axis of the adjusting stem 176. The shunt assembly 17 is provided with a throttling hole 177 which is in plug-in cooperation with the adjusting stem 176. In this way, 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 shunt assembly 17 can be relatively displaced towards the first water supply port 1144, so as to separate the shunt assembly 17 from the backflow guide portion 1171, and change the throttling gap between the adjusting stem 176 and the throttling hole 177 according to the pressure difference, thereby effectively adjusting the increasing variable of the pure water flowing into the water outlet cavity 1148.

[0071] It can be understood that, in the case that the water outlet amount of the first water supply port 1144 is large, the pressure difference formed by the pure water inlet 1143, the first water supply port 1144 and the second water supply port 1145 is large, the shunt assembly 17 will be close to the first water supply port 1144 along the central axis of the adjusting stem 176, the throttling gap between the adjusting stem 176 and the throttling hole 177 becomes large, the adjusting stem 176 and the throttling hole 177 are separated, and the throttling gap reaches the maximum extent, so that the volume flow rate (hereinafter referred to as flow rate) of the pure water passing through the throttling gap is increased to the maximum extent, and part of the pure water is also supplemented into the water outlet upper cavity 11482 through the throttling gap. Therefore, when the water consumption of the water terminal changes in a large range, the increasing variable of the pure water flowing into the water outlet cavity 1148 can be changed through the throttling gap. Here, the increasing variable should be understood as a physical quantity that the volume flow rate of the pure water increases with the change of the throttling gap during the flow through the throttling gap. Thus, the problem that the maximum and minimum flow rate ranges that can be adjusted are limited due to the variation of the overflow hole of the existing shunt 1 is solved, so that the water pressure between different water terminals (such as faucets and water tankless pipeline machines) can be balanced to a certain extent, and the water flow distribution is more reasonable. It can be understood that, when the pressure difference decreases, the throttling gap will be reduced by the reset of the shunt assembly 17. At this time, the pure water flowing through the throttling gap will be reduced to the minimum extent, or even almost not flow through the throttling gap.

[0072] It should be noted that when the throttling gap is zero, that is, the peripheral wall of the adjusting column core 176 abuts against the inner hole wall of the sealing throttling hole 177, at this time, the purified water almost cannot flow through the adjusting column core 176 and the throttling hole 177, and all the purified water will flow through the overflow hole into and out of the water upper cavity 11482. The adjusting column core 176 and the throttling hole 177 form an overflow gap, at this time, the shunt assembly 17 abuts against the backflow guide part 1171, and the throttling gap is reduced to the minimum, therefore, the overflow gap is the space where the throttling gap is at the minimum, and a small part of the purified water can still flow through the overflow gap into and out of the water upper cavity 11482, then the shunt assembly 17 can cancel the overflow hole, or can also retain the overflow hole, so that the overflow hole cooperates with the overflow gap.

[0073] In this way, the following unexpected effects can be achieved:

[0074] 1. The adjusting column core 176 is fixedly connected to the valve body lower shell 117 and is arranged in the extension direction of the backflow guide part 1171, and the length of the adjusting column core 176 is long enough, so that the linear range of displacement is larger under the action of the pressure difference formed by the purified water inlet 1143, the first water supply port 1144 and the second water supply port 1145. For example, in the case of large change of the pressure difference, the longer adjusting column core 176 can more accurately generate corresponding displacement according to the size of the pressure difference. This accurate displacement can more finely change the throttling gap between the adjusting column core 176 and the throttling hole 177, so as to realize more accurate flow regulation. Just like a longer lever can more accurately control the transmission of force, the longer adjusting column core 176 can more accurately adjust the water flow according to the change of water pressure, reducing the probability of limited adjustment range.

[0075] 2. The arrangement mode of the longer adjusting column core 176 on the valve body lower shell 117 also helps to enhance the stability of the entire shunt 1. Because it can more accurately displace and regulate the flow according to the water pressure difference, the water flow distribution of the shunt 1 under different water conditions or water scenes is more reasonable and efficient. For example, when the water consumption of the tankless pipeline machine suddenly changes, the longer adjusting column core 176 can quickly respond and fully adjust the throttling gap to avoid sudden fluctuations in water pressure from damaging the shunt 1, which is equivalent to a stabilizer maintaining the balance of the shunt 1 when the water flow changes, preventing problems such as tankless pipeline machine failure and abnormal water output caused by unstable water pressure. And once the distance of the throttling gap is adjusted, the flow of purified water is relatively stable. In the process of long-term use, the risk of being blocked is also reduced, thereby better ensuring the use stability of the shunt assembly 17 and the shunt 1, and reducing the cost of processing and manufacturing and the cost of later maintenance.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] It should be noted that the throttling area of the throttling gap in the maximum state is between 3.3-3.7 square millimeters. When the water tankless pipeline machine needs a larger flow of pure water, this area range can ensure that enough pure water flows into the outlet upper cavity 11482 quickly to meet the water demand of the water tankless pipeline machine, and will not limit the water supply because the throttling gap is too small. At the same time, it is also helpful to maintain a reasonable pressure distribution in the outlet cavity 1148. When the pure water passes through the throttling gap of this area range, according to the principle of fluid mechanics, a certain pressure drop will be generated. This pressure drop can balance the pressure difference between the pure water inlet 1143, the first water supply port 1144 and the second water supply port 1145. For example, when the water tankless pipeline machine is used, the larger throttling gap area can balance the pressure on both sides of the shunt assembly 17 while allowing enough water flow into the outlet upper cavity 11482. If the throttling gap area is too small, the pressure difference between the outlet lower cavity 11481 and the outlet upper cavity 11482 will be too large, which will affect the stability of the shunt 1 and the normal operation of the water tankless pipeline machine. In addition, when the water usage changes, the shunt 1 can adjust the throttling area of the actual throttling gap flexibly within this area range to avoid sudden changes in water flow or pressure fluctuations caused by an inappropriate throttling gap area. For example, when the water usage of the water tankless pipeline machine suddenly increases or decreases, the shunt 1 can quickly adjust within this area range to maintain stable water supply and reduce the impact on the water tankless pipeline machine, prolonging the service life of the shunt 1 and the water tankless pipeline machine. The throttling area of the throttling gap in the maximum state is preferably 3.5 square millimeters.

[0081] When the throttling area of the throttling gap in the maximum state exceeds 3.7 square millimeters, the larger throttling area will make the pressure difference on both sides of the shunt assembly 17 smaller. When the water tankless pipeline machine uses boiling water (i.e., when the water tankless pipeline machine needs a smaller flow of pure water), it will be easy to cause the guide flow channel 1172 controlled by the shunt assembly 17 to fail to open, thereby causing the water purifier to frequently start and stop.

[0082] When the throttling area of the throttling gap in the maximum state is less than 3.3 square millimeters, the smaller throttling area will cause the water tankless pipeline machine to use normal temperature water (i.e., when the water tankless pipeline machine needs a larger flow of pure water) to flow too quickly, causing the outlet pure water position of the water purifier to rise in pressure, exceeding the start-stop value of the high-pressure switch of the water purifier and causing frequent starting problems.

[0083] Preferably, the throttling area of the flow gap formed between the adjusting core 176 and the throttling hole 177 is between 0.9 and 1.1 square millimeters, that is, when the shunt assembly 17 abuts against the backflow guide portion 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.

[0084] Thus arranged, not only is small-flow water supply ensured, for example, when the net drinking system is in a low-flow operation mode or the tankless pipeline machine needs small-flow pure water, this throttling area range provides good regulation accuracy and finely allocates the flow of pure water. At the same time, it also helps to maintain the stability of the pressure in the water outlet cavity 1148. According to the principle of fluid mechanics, the throttling area in this range can generate a certain resistance when the pure water passes through, so that the pressure change in the water outlet cavity 1148 is relatively moderate, and to some extent, it can effectively prevent the backflow of pure water. Because the throttling area of the throttling gap is small, under the normal pressure difference range, the pure water is not easy to flow in the opposite direction, ensuring the unidirectionality of the water flow in the shunt 1, improving the reliability of the shunt 1, and also ensuring stable water supply of the shunt 1 when the water consumption is relatively small. When the throttling area of the throttling gap in the minimum state is less than 0.9 square millimeters, it is easy to cause the throttling area to be small, which is not conducive to the mold making of the shunt assembly 17. When the throttling area of the throttling gap in the minimum state is greater than 1.1 square millimeters, it is easy to cause the throttling area to be large, which will increase the minimum flow required to ensure that the tankless pipeline machine does not frequently start and stop when taking water.

[0085] It should also be noted that the specific embodiments are described in combination with Figure 2 and Figure 3 It is shown that the adjusting core 176 is at least partially positioned near the first water inlet 1144 with a smaller cross-sectional area than that away from the first water inlet 1144. Preferably, the cross-sectional area of the at least partially positioned adjusting core 176 gradually decreases along the central axis of the adjusting core 176 and towards the first water inlet 1144. The cross section here is the cross section of the adjusting core 176 perpendicular to the central axis thereof.

[0086] On one hand, the flow regulating assembly 17 can achieve gradual flow regulation under different displacement conditions. When the adjusting core 176 moves to the first water outlet 1144 according to the pressure difference, due to the gradual change of the cross-sectional area, the change of the cross-sectional area of the channel formed between the adjusting core 176 and the throttling hole 177 is not sudden, but a gradual change process, thereby avoiding the impact of sudden change of flow on the system. On the other hand, this gradual cross-sectional area design can effectively expand the range of flow regulation. When the displacement of the adjusting core 176 is large, the part with small cross-sectional area cooperates with the throttling hole 177 to allow larger flow to pass; when the displacement is small, the part with large cross-sectional area cooperates with the throttling hole 177 to limit the flow. This makes the flow divider 1 better adapt to a wider range of water demand, whether it is fine water supply with small flow or rapid water supply with large flow.

[0087] In addition, during the flow of pure water, the gradual change of the cross-sectional area of the adjusting core 176 can play a role in buffering the change of water pressure. When the water flow passes through the part with gradually decreasing cross-sectional area, according to Bernoulli's principle, the water flow velocity will gradually increase, and the water pressure will gradually decrease. This gradual change of water pressure can avoid damage to the system caused by sudden change of water pressure. And between the lower water outlet cavity 11481 and the upper water outlet cavity 11482, the gradual change of the cross-sectional area of the adjusting core 176 helps to balance the pressure difference between the two chambers. Because the cross-sectional area can regulate the water flow velocity and water pressure, when the pressure difference between the two chambers changes, by adjusting the displacement of the adjusting core 176 and using the part with gradually changing cross-sectional area to guide the water flow, the pressure difference between the two chambers can be gradually balanced. This is very important for stable water distribution and normal operation of the flow divider 1, and also ensures that the water terminal can obtain stable water supply pressure.

[0088] Next, the specific structure of the above-mentioned flow regulating assembly 17 will be described in detail in combination with the drawings.

[0089] Specifically, as shown in Figure 3 , Figure 4 and Figure 5 , the flow regulating assembly 17 comprises a flow regulating balance membrane 172 and a balance spring 171, the flow regulating balance membrane 172 is detachably connected between the upper valve body shell 116 and the lower valve body shell 117, and the upper valve body shell 116 cooperates with the flow regulating balance membrane 172 to form the upper water outlet cavity 11482, the lower valve body shell 117 cooperates with the flow regulating balance membrane 172 to form the lower water outlet cavity 11481, and the balance spring 171 is arranged between the flow regulating balance membrane 172 and the inner cavity wall of the upper water outlet cavity 11482.

[0090] The shunt balance film 172 is made of elastic material (such as silica gel, rubber, etc.), and a diaphragm through hole 1724 is arranged on the shunt balance film 172. The overflow hole is the diaphragm through hole 1724, and the overflow hole can also be elastically stretched at this time. Further, the diaphragm adjusting hole 1728 is also arranged on the shunt balance film 172, and the throttle hole 177 is the diaphragm adjusting hole 1728 at this time. When the water consumption of the tankless pipeline machine is small, the pressure difference is low, and the throttle gap is small or the minimum overflow gap, only a small part of the purified water flows through the overflow hole and / or the overflow gap into and out of the water upper cavity 11482. In this case, the overflow gap plays a role in fine adjustment of the flow, ensuring that the flow distributor 1 can still stably distribute a small amount of purified water at low flow demand. When the water consumption of the tankless pipeline machine increases, the pressure difference increases, and the throttle gap between the adjusting column core 176 and the throttle hole 177 increases. At this time, most of the purified water is allowed to flow into the water upper cavity 11482 through the increased throttle gap, so that the flow through the flow distributor 1 can be accurately adjusted according to different working conditions (such as different water consumption speeds of the tankless pipeline machine), effectively reducing the probability of frequent start and stop of the water purifier. At the same time, since the throttle gap also serves as an auxiliary water flow channel, it can balance the water pressure under different water consumption situations to some extent, ensuring more reasonable water flow distribution. Of course, through the cooperation of the overflow hole and the throttle gap on the shunt balance film 172, the pressure balance on both sides of the shunt assembly 17 can be better maintained.

[0091] Therefore, when the water consumption of the tankless pipeline machine is large, the pressure on the side of the shunt balance film 172 close to the first water inlet 1144 is greatly different from the pressure on the side of the shunt assembly 17 away from the first water inlet 1144, the shunt balance film 172 will elastically deform towards the side of the first water inlet 1144, and the balance spring 171 will be compressed. When the water consumption of the tankless pipeline machine decreases, the pressure difference on both sides of the shunt balance film 172 decreases, and the first water inlet 1144 has little purified water flow, which means that there is no corresponding pressure due to the flow of purified water. At this time, the state on both sides of the shunt balance film 172 returns to the initial balanced state, and under the action of the elastic deformation of the shunt balance film 172 itself and the elastic deformation of the balance spring 171, the side of the shunt balance film 172 away from the first water inlet 1144 deforms to recover, until the shunt balance film 172 abuts against the backflow guide portion 1171 to seal the guide flow channel 1172. Such an arrangement will have the following unexpected effects:

[0092] 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.

[0093] 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.

[0094] 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.

[0095] As a preferred embodiment, please refer to the following for details. Figure 3 , Figure 4 and Figure 5As shown, the shunt assembly 17 further comprises a diaphragm top cover 173, the diaphragm top cover 173 is provided with a top cover through hole, the top cover through hole is communicated with the diaphragm through hole 1724, at this time, the top cover through hole and the diaphragm through hole 1724 constitute the overflow hole, the diaphragm top cover 173 is arranged on the side of the shunt balance diaphragm 172 close to the first water inlet 1144. Further, the diaphragm top cover 173 is further provided with a top cover adjusting hole 1737, the top cover adjusting hole 1737 is communicated with the diaphragm adjusting hole 1728, then the top cover adjusting hole 1737 and the diaphragm adjusting hole 1728 constitute the throttle hole 177. One end of the balance spring 171 abuts against the inner cavity wall of the water outlet upper cavity 11482, 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 of the balance spring 171, and the diaphragm top cover 173 has good structural strength. During the shunting process, the balance spring 171 can adjust the balance of the system through the force between the diaphragm top cover 173 and the inner cavity wall. For example, when the flow of pure water changes or the internal pressure of the water outlet upper cavity 11482 fluctuates, the balance spring 171 can stretch and contract according to the position change of the diaphragm top cover 173, so as to adjust the pressure balance and flow balance of the shunt 1, and ensure the stability of the shunting.

[0096] Further, as shown in Figure 3 , Figure 4 and Figure 5 , the shunt assembly 17 has a stop limiting portion 1733 protruding towards the side of the first water inlet 1144, so that the shunt assembly 17 moves relatively towards the side of the first water inlet 1144 until the stop limiting portion 1733 abuts against the inner cavity wall of the water outlet cavity 1148, specifically, the stop limiting portion 1733 abuts against the inner cavity wall of the water outlet upper cavity 11482, at this time, the shunt assembly 17 has the maximum displacement. In this way, the stop limiting portion 1733 can abut against the inner cavity wall of the water outlet upper cavity 11482 under a large pressure difference, forming a reliable mechanical limiting, effectively limiting the further movement of the shunt assembly 17, thereby preventing the shunt balance diaphragm 172 from being deformed too much due to excessive stress, eliminating the hidden danger that the shunt balance diaphragm 172 is damaged due to excessive deformation, and improving the service life of the shunt 1.

[0097] Preferably, as shown in 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.

[0098] The unexpected effect is that, Figure 3 to Figure 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.

[0099] 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.

[0100] Meanwhile, under the action of the water passing gap 1736, the stop limiting portion 1733 abuts against the inner wall of the water outlet upper cavity 11482, and the pure water can still flow to the first water supply port 1144 through the water passing gap 1736, ensuring the smoothness, stability and continuity of the pure water flow, and preventing the pure water from being blocked by the stop limiting portion 1733 to cause sudden changes in water flow pressure, thereby ensuring the stability and reliability of the use of the flow divider 1 and the pure drinking system.

[0101] Of course, it should also be noted that, in addition to the stop limiting portion 1733 on the above-mentioned flow dividing assembly 17 abutting against the inner wall of the water outlet upper cavity 11482, the specific combination of Figure 1 to Figure 3 As shown in the drawings, the inner wall of the water outlet upper cavity 11482 is protruded on the side facing the flow dividing assembly 17 to form a stop protrusion 1161, specifically, the stop protrusion 1161 is protruded on the side of the inner wall of the water outlet upper cavity 11482 facing the flow dividing assembly 17, and the stop protrusion 1161 is preferably integrally formed with the valve body upper shell 116 to facilitate production. The inside of the stop protrusion 1161 is provided with a first water supply channel 1162 communicating with the first water supply port 1144, and the stop limiting portion 1733 can abut against the stop protrusion 1161.

[0102] On the one hand, the stop protrusion 1161 cooperates with the stop limiting portion 1733 on the diaphragm top cover 173 to more accurately limit the deformation degree of the flow dividing balance membrane 172. When the flow dividing balance membrane 172 deforms in the direction of the first water supply port 1144 under the action of water flow, water pressure and other factors, the stop limiting portion 1733 abuts against the stop protrusion 1161, thereby further preventing the flow dividing balance membrane 172 from deforming excessively and better ensuring that the flow dividing balance membrane 172 works within a safe range. On the other hand, the pure water will be orderly drained to the first water supply port 1144 through the first water supply channel 1162, so that the water flow is more concentrated and stable to the target outlet, avoiding water flow disorder, thereby improving the working efficiency and accuracy of the flow divider 1.

[0103] Preferably, as shown in Figure 1 , Figure 2 and Figure 3 , the inner wall of the flow channel of the first water supply channel 1162 is protruded to form a spring force body 1163, which can be optionally extended along the circumference of the first water supply channel 1162, or the number of spring force bodies 1163 is configured to be multiple, each spring force body 1163 can be optionally a hemispherical body or a prism, and multiple spring force bodies 1163 are arranged along the circumference of the first water supply channel 1162. As shown in 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 body 1163. At this time, the spring force body 1163 provides a fixed support point for the end of the balance spring 171, so that the position of the balance spring 171 is more stable during operation, that is, the end of the balance spring 171 abuts against the spring force body 1163, and the side of the balance spring 171 can contact the inner wall of the flow channel of the first water supply channel 1162, which well avoids the vibration or slight displacement of the balance spring 171 during operation, so as to better ensure that the balance spring 171 can normally play its balancing and adjusting functions, and more accurately transmit the force, thereby ensuring and improving the flow distribution accuracy of the flow distributor 1.

[0104] Of course, in order to facilitate the assembly of the end of the balance spring 171 into the first water supply channel 1162, please refer to Figure 1 , Figure 2 and Figure 3 As shown, the port of the first water supply channel 1162 for communicating the water outlet upper cavity 11482 is a second flow guide port, and the second flow guide port is provided with a positioning guide portion 1164, which is connected to the inner wall of the flow channel of the first water supply channel 1162 in the direction of the central axis of the first water supply channel 1162. Therefore, during assembly, the end of the balance spring 171 only needs to abut against the positioning guide portion 1164, and under the guidance of the positioning guide portion 1164, the balance spring 171 will automatically slide into the first water supply channel 1162, achieving the purpose of automatic positioning and improving the assembly efficiency and convenience of the balance spring 171.

[0105] As another preferred mode of the present embodiment, please refer to Figure 3 , Figure 4 and Figure 5As shown, the shunt assembly 17 further comprises a diaphragm base 174, which is provided with a base through hole 1741 that is in communication with the diaphragm through hole 1724. Understandably, when the shunt assembly 17 is not provided with the diaphragm cover 173, the base through hole 1741 and the diaphragm through hole 1724 form the overflow hole. Alternatively, when the shunt assembly 17 is provided with the diaphragm cover 173, the shunt balance diaphragm 172 is clamped between the diaphragm cover 173 and the diaphragm base 174, and the cover through hole, the diaphragm through hole 1724, and the base through hole 1741 form the overflow hole. The diaphragm base 174 is arranged on the side of the shunt balance diaphragm 172 away from the first water inlet 1144. In this way, when the flow of purified water from the first water inlet 1144 suddenly decreases, if the water inflow of the water purifier cannot be adjusted in time, the pressure in the water outlet upper cavity 11482 will rapidly rise. In this case, the diaphragm base 174 can provide strong support for the shunt balance diaphragm 172. The diaphragm base 174 has a certain structural strength, and due to the supporting effect of the diaphragm base 174, the shunt balance diaphragm 172 will not deform excessively towards the reflux guide portion 1171 side due to the reverse pressure. Thus, the stability and reliability of the entire shunt assembly 17 are ensured, avoiding blockage or other failures caused by excessive deformation of the shunt balance diaphragm 172, ensuring that the water purifier can continuously and stably operate under different working conditions, effectively improving the working efficiency and service life of the water purifier, and also providing users with a more reliable water purification experience.

[0106] It should be noted that the specific embodiments are described in detail in Figure 3 , Figure 4 and Figure 5 . Figure 3 , Figure 4 and Figure 5 .

[0107] Understandably, the "pressure difference formed by the purified water inlet 1143, the first water inlet 1144, and the second water inlet 1145" described above is equivalent to the difference between the pressure on the side of the diaphragm cover 173 and the pressure on the side of the diaphragm base 174, that is, the pressure difference on both sides of the shunt balance diaphragm 172.

[0108] Further, the specific embodiments are described in detail in Figure 3 , Figure 4 and Figure 5 .As shown, the membrane base 174 is further provided with a base avoiding hole 1742, the size of the base avoiding hole 1742 is larger than the diameter of the backflow guide part 1171, the backflow guide part 1171 can pass through the base avoiding hole 1742 and abut against the shunt balance membrane 172. In the embodiment, the shape of the base avoiding hole 1742 is not limited, for example, it can be a circular hole, or a square hole, or an oval hole, etc. In this way, the shunt balance membrane 172 can accurately seal the guide flow channel 1172, thereby effectively blocking the backflow path of the purified water. This also ensures that in the normal shunt working state, the water flow can flow in order according to the predetermined shunt channel, avoiding the unnecessary loss or backflow of the purified water to interfere with the normal water flow process. At the same time, by using the flexibility of the shunt balance membrane 172, the sealing between the shunt balance membrane 172 and the backflow guide part 1171 is improved.

[0109] As another preferred mode of the embodiment, please combine Figure 4 and Figure 5 As shown, the membrane top cover 173 extends a guide extension body 175 towards the membrane through hole 1724, the guide extension body 175 is preferably integrally formed with the membrane top cover 173, and a water passing through hole 1751 is provided inside the guide extension body 175. Here, the through hole should be understood as the water passing through hole 1751 penetrating both ends of the guide extension body 175 along the extension direction of the guide extension body 175. The guide extension body 175 is inserted into the membrane through hole 1724, at this time, the top cover through hole, the membrane through hole 1724, the base through hole 1741 and the water passing through hole 1751 constitute the flow hole. The purified water flows through the water passing through hole 1751, which is equivalent to the purified water flowing from the water outlet lower cavity 11481 through the base through hole 1741, the membrane through hole 1724 and the top cover through hole in turn, and finally flowing into the water outlet upper cavity 11482.

[0110] In this way, the water passing through hole 1751 not only plays a good guiding role in the flow of purified water, but also makes the flow of purified water in the flow hole more orderly and smooth, reducing the turbulence and energy loss of the water flow. At the same time, the close and orderly connection structure between the components can accurately insert the membrane through hole 1724 of the shunt balance membrane 172 and the base through hole 1741 of the membrane base 174 in the assembly process, improving the positioning accuracy and assembly efficiency.

[0111] Further, please combine Figure 4 and Figure 5As shown, the flow guide extension 175 passes through the top cover through hole, the diaphragm through hole 1724, the base through hole 1741 in turn and extends out of the base through hole 1741. The part of the flow guide extension 175 extending out of the base through hole 1741 is provided with a buckle protrusion 1752, and the buckle protrusion 1752 is clamped on the diaphragm base 174. Thus, the diaphragm top cover 173 and the diaphragm base 174 are clamped and connected, so as to ensure that the shunt balance membrane 172 is clamped between the diaphragm top cover 173 and the diaphragm base 174. This is beneficial to the convenience and efficiency of disassembly, thereby facilitating the replacement of subsequent components. Moreover, the structure is simple, and the processing cost of each component is reduced. Of course, the side of the diaphragm base 174 away from the shunt balance membrane 172 can be provided with a base clamping groove, and the buckle protrusion 1752 is clamped in the base clamping groove.

[0112] Preferably, the flow guide extension 175 is located inside the top cover through hole, 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 shunt balance membrane 172 through the buffer gap during assembly, which is beneficial to assembly positioning and further improves assembly efficiency. At the same time, the buffer gap serves as a space for deformation of the flow guide extension 175 during clamping, thereby facilitating the clamping of the buckle protrusion 1752 on the diaphragm base 174 or the disassembly of the buckle protrusion 1752 from the diaphragm base 174.

[0113] It should be noted that in other embodiments, the flow guide extension 175 can also be arranged to extend from the diaphragm base 174 towards the diaphragm through hole 1724, and the flow guide extension 175 passes through the base through hole 1741, the diaphragm through hole 1724, and the top cover through hole in turn and extends out of the top cover through hole. The part of the flow guide extension 175 extending out of the top cover through hole is provided with a buckle protrusion 1752, and the buckle protrusion 1752 is clamped on the diaphragm top cover 173, which belongs to a conventional replacement mode of the above-mentioned preferred embodiment.

[0114] It should also be noted that the specific embodiments are described in combination with Figure 4 and Figure 5As shown, the diameter of the water passing through hole 1751 is smaller on the side close to the diaphragm base 174 than on the side close to the diaphragm top cover 173. Preferably, the diameter of the water passing through hole 1751 gradually increases along the water flow direction, which is the direction from the base through hole 1741 to the diaphragm through hole 1724 and the top cover through hole, as described above. Therefore, the diameter of the water passing through hole 1751 gradually increases along the first direction, which is the direction from the diaphragm base 174 to the diaphragm top cover 173 along the central axis of the water passing through hole 1751. In this way, when the purified 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 passing through hole 1751 gradually increases. According to the flow formula Q = vA (Q is the flow, v is the flow rate, and A is the cross-sectional area), the flow rate decreases when the cross-sectional area increases while the flow remains substantially unchanged. A lower flow rate can reduce the pressure loss of the water flow in the water passing through hole 1751. At the same time, when the purified water flows into the water passing through hole 1751 from the side with the smaller diameter, a relatively orderly flow state can be formed. As the diameter gradually increases, the purified water has enough space to transition smoothly, reducing turbulence caused by sudden changes in space, thereby effectively avoiding the generation of small bubbles in the purified water. In addition, the side with the smaller diameter can also limit the impact of the water flow. This reduces physical damage, such as scratching, to the water passing through hole 1751 and the shunt balancing membrane 172.

[0115] In the above, the pressure on the side of the shunt balancing membrane 172 close to the first water inlet 1144 is significantly different from the pressure on the side of the shunt assembly 17 away from the first water inlet 1144. The shunt balancing membrane 172 will elastically deform towards the side of the first water inlet 1144 and move the diaphragm top cover 173 and / or the diaphragm base 174 towards the side of the first water inlet 1144. In order to ensure and improve the large elastic deformation of the shunt balancing membrane 172 towards the side of the first water inlet 1144, such as Figure 4 and Figure 5 As shown, the shunt balancing membrane 172 is provided with a deformation groove 1725, which is a U-shaped groove. The deformation groove 1725 is located outside the diaphragm adjusting hole 1728 and extends along the circumference of the diaphragm top cover 173. It can be understood that the orientation of the slot of the deformation groove 1725 can be set and adjusted according to the structural design and design requirements. In this embodiment, the slot of the deformation groove 1725 is preferably oriented towards the water outlet lower cavity 11481.

[0116] In this way, when the shunt balance membrane 172 is subjected to pressure, the circumferentially extending deformation groove 1725 can provide sufficient space for the deformation of the shunt balance membrane 172, not only making the stress concentrated in the deformation groove 1725, but also enabling the stress to be effectively released, producing uniform deformation, thereby well avoiding the risk of excessive stress concentration in other parts of the shunt balance membrane 172 to cause rupture and fatigue damage. At the same time, it can also effectively enhance the deformation ability of the shunt balance membrane 172 in a limited space. When the shunt balance membrane 172 is affected by the pressure change in the water outlet cavity 1148, the deformation groove 1725 can serve as a pre-set deformation area, better guiding the shunt balance membrane 172 to produce a larger deformation, so that the shunt balance membrane 172 can respond sensitively according to these pressure differences, achieving the purpose of better balancing the pressure in all directions, which is conducive to the shunt assembly 17 to control the shunt more accurately.

[0117] Further, as shown in Figure 3 , Figure 4 and Figure 5 , the groove wall of the deformation groove 1725 away from the membrane adjusting hole 1728 is outwardly protruding and formed with a membrane clamping portion 1726. Preferably, the membrane clamping portion 1726 is arranged on the groove wall of the deformation groove 1725 close to the slot opening, and the membrane clamping portion 1726 is integrally formed with the shunt balance membrane 172. The membrane clamping portion 1726 extends along the groove length direction of the deformation groove 1725 and is clamped between the valve upper shell 116 and the valve lower shell 117, thereby achieving the purpose of detachably connecting the shunt balance membrane 172 between the valve upper shell 116 and the valve lower shell 117, and improving the assembly efficiency of the shunt device 1.

[0118] Specifically, as shown in Figure 2 to Figure 5 , the valve lower shell 117 is provided with a membrane clamping groove 1173, and the membrane clamping portion 1726 is embedded in the inside of the membrane clamping groove 1173, so that the membrane clamping portion 1726 is more firmly connected between the valve upper shell 116 and the valve lower shell 117, and the shunt balance membrane 172 can be more firmly assembled on the valve shell 11. In addition, the groove wall of the membrane clamping groove 1173 close to the throttle hole 177 extends towards the inside of the deformation groove 1725, that is, the groove wall of the membrane clamping groove 1173 close to the throttle hole 177 is accommodated in the inside of the deformation groove 1725, so that the shunt assembly 17 and the valve shell 11 are more compact, which is conducive to reducing the volume of the shunt device 1. It should be noted that, in addition to the membrane clamping groove 1173 being arranged on the valve lower shell 117, the membrane clamping groove 1173 can also be arranged on the valve upper shell 116.

[0119] Preferably, as shown in Figure 2 to Figure 5As shown, the valve body upper shell 116 is provided with a diaphragm anti-falling groove 1165, and the diaphragm clamping portion 1726 is provided with a diaphragm anti-falling body 1727 inserted into the diaphragm anti-falling groove 1165, thereby further improving the stability of the connection between the shunt balance diaphragm 172 and the valve shell 11. It can be understood that the diaphragm clamping groove 1173 is arranged on the valve body upper shell 116, and the diaphragm anti-falling groove 1165 is correspondingly arranged on the valve body lower shell 117.

[0120] In the pure drinking system, when the user starts or turns off the tankless pipeline machine, the water flow rate of the pure water flowing through the shunt 1 will change sharply, thereby causing a water hammer phenomenon. The instantaneous pressure wave generated by the water hammer may cause damage to the shunt assembly 17 in the shunt 1. Based on this, the inventor also provides a preferred mode, please see Figure 3 The shunt 1 further comprises a water hammer absorber 18, which is located between the shunt assembly 17 and the pure water inlet 1143, and is detachably connected to the valve shell 11. Specifically, the water hammer absorber 18 is installed inside the water outlet lower cavity 11481, so that the pressure wave generated by the water hammer is buffered before entering the water outlet upper cavity 11482. Further, the water hammer absorber 18 is further provided with an absorber adjusting hole 184, and the adjusting column core 176 is inserted into the absorber adjusting hole 184, and the adjusting column core 176 can penetrate the absorber adjusting hole 184, so that the adjusting column core 176 can extend to the throttling hole 177 of the shunt assembly 17 and be inserted into cooperation with the throttling hole 177.

[0121] It should be noted that the hole diameter of the absorber adjusting hole 184 is preferably larger than the diameter of the adjusting column core 176, so that a gap is formed between the absorber adjusting hole 184 and the adjusting column core 176, so as to facilitate the insertion assembly between the adjusting column core 176 and the water hammer absorber 18, and also facilitate the smooth and stable flow of water through the gap between the absorber adjusting hole 184 and the adjusting column core 176.

[0122] In this way, the pressure wave can be buffered before reaching the shunt assembly 17, reducing the risk of damage to the shunt assembly 17 caused by the high pressure generated by the water hammer, and improving the service life of the shunt assembly 17. At the same time, since the water hammer absorber 18 absorbs part of the energy, it can reduce the vibration and noise generated by the water flow impacting the valve shell 11. In addition, under the action of the water hammer absorber 18, the stability of the shunt assembly 17 during the adjustment process can be ensured, the interference of the water hammer on the shunting process is reduced, the normal operation of the shunt 1 is ensured, and the shunting precision of the shunt 1 is improved.

[0123] Preferably, please refer to Figure 3 and Figure 6As shown, the water hammer absorbing member 18 is provided with a plurality of water flow buffering holes 181, which are uniformly distributed, and the water outlet cavity 1148 is connected to the purified water inlet 1143 through the plurality of water flow buffering holes 181. When the purified water flows into the purified water inlet 1143 and passes through the water hammer absorbing member 18 with the water flow buffering holes 181, the water flow buffering holes 181 play a role of buffering the water flow. Because the flow direction and speed of the purified water will change when it flows through the water flow buffering holes 181. For example, the purified water flowing rapidly will be dispersed into a plurality of small water flows and consume part of the kinetic energy of the water flow when it passes through the plurality of water flow buffering holes 181, thereby reducing the degree of mutation of the water flow speed and alleviating the possibility of water hammer.

[0124] In addition, the existence of the water flow buffering holes 181 can also adjust the pressure change of the water flow. According to Bernoulli's principle, when the water flow passes through the water flow buffering holes 181, a certain pressure difference will be formed on both sides of the water hammer absorbing member 18, which plays a certain degree of adjustment. At the same time, due to the existence of the water flow buffering holes 181, the purified water will flow to a certain extent under the action of the pressure difference, which can alleviate the sharp rise of the pressure and make the pressure change more gentle, further reducing the water hammer phenomenon.

[0125] It should be noted that the number, size and distribution of the water flow buffering holes 181 are not limited in the present application, and can be set and adjusted according to the structure design and design requirements. By reasonably setting the number, size and distribution of the water flow buffering holes 181, the pulse frequency of the purified water flow can also be changed. For example, when the water hammer phenomenon occurs, high-frequency pressure pulses will appear. The water flow buffering holes 181 are configured in a combination of large holes and small holes, wherein the large holes allow a larger flow of water to pass through, and the small holes have more restrictions on the water flow, so that the high-frequency pressure pulses can be converted into relatively low-frequency pulses (i.e. the irregular pulses become more regular), and the low-frequency and regular pressure change has relatively small impact on the flow divider 1, thereby also helping to alleviate the harm of water hammer.

[0126] Further, please refer to Figure 3 , Figure 6 and Figure 7As shown, the water hammer absorbing member 18 is provided with a positioning assembly hole 182 for inserting the backflow guide part 1171, and the diameter of the positioning assembly hole 182 is matched with the diameter of the backflow guide part 1171, so as to quickly and stably install the backflow guide part 1171 on the valve body lower shell 117 of the valve shell 11. In order to ensure that the water hammer absorbing member 18 can be more stably installed on the valve body lower shell 117, and the stress between the water hammer absorbing member 18 and the valve body lower shell 117 is more balanced, the inner wall of the outlet lower cavity 11481 is protruded to form an absorbing member boss 1174, and the edge of the water hammer absorbing member 18 abuts against the absorbing member boss 1174, which is simple in structure, convenient to disassemble and assemble, and beneficial to subsequent maintenance and repair.

[0127] Of course, the specific implementation is based on the description of Figure 3 、 Figure 6 and Figure 7 , the absorbing member boss 1174 is protruded to form a limiting protrusion 1175 towards one side of the shunt assembly 17, and the edge of the water hammer absorbing member 18 is provided with a limiting gap 183 for inserting the limiting protrusion 1175. In this way, the limiting gap 183 and the limiting protrusion 1175 cooperate to prevent the water hammer absorbing member 18 from being deflected around the backflow guide part 1171, thereby more stably guiding the flow of pure water.

[0128] In other embodiments, the water hammer absorbing member 18 described above can also be a piston type water hammer eliminator, or can also be a diaphragm type water hammer eliminator, both of which are relatively mature existing technologies in water hammer eliminators, and the structure will not be described in detail here. Alternatively, the water hammer absorbing member 18 described above can also be a slow closing check valve.

[0129] The above is the explanation and description of the shunt assembly proposed in the embodiments of the present application, and since the pure drinking system proposed in the embodiments of the present application adopts all the technical solutions of the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.
