[0038] In order to make the purpose, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail with reference to the accompanying drawings.

[0039] The description of the following exemplary embodiments is not meant to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0040] In the description of the present application, it should be understood that the terms "first", "second" and the like are used to describe various elements, but not to imply or suggest relative importance. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, "a plurality of" means two or more, unless otherwise specified. The "and / or" describes the association between the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. The character " / " generally represents an "or" relationship between the associated objects before and after it.

[0041] 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 in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0042] One aspect of the present application proposes a pure drinking system, which includes a water purifier, a water tank-free 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 tank-free 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 different drinking water temperature requirements of the user. It should be noted that the water purifier, the water tank-free pipeline machine and the faucet all belong to relatively mature existing technologies in the art, and the present application does not make significant improvements to the water purifier, the water tank-free pipeline machine and the faucet. Therefore, the structure of the water purifier, the water tank-free pipeline machine and the faucet is not described in detail, and the type and model of the water purifier and the water tank-free pipeline machine are not limited.

[0043] The purified water source is simultaneously distributed to the tankless pipeline machine and the faucet, improving water utilization efficiency. The outlet end of the water purifier is usually configured with a flow divider valve. The water inlet end of the tankless pipeline machine and the water inlet of the faucet are connected to the flow divider valve. When the user needs to take temperature-adjusted direct drinking water, such as 5-15℃ ice water in hot summer, 40-50℃ warm water for washing milk powder, or 90-99℃ hot water for making tea, the user can open the tankless pipeline machine to take it. When the user needs to take domestic water to wash dishes or wash fruits and vegetables or wash clothes, the user can open the faucet to take it.

[0044] Specifically, please refer to Figure 1 and Figure 2 The flow divider 1 includes a valve housing 11, which includes a valve body upper housing 116 and a valve body lower housing 117 connected to each other. The connection between the valve body upper housing 116 and the valve body lower housing 117 is detachable, such as bolt connection, clamping connection, etc., to facilitate the production of the valve body upper housing 116 and the valve body lower housing 117, and effectively improve the assembly efficiency and reduce the assembly difficulty. In this embodiment, the valve body upper housing 116 and the valve body lower housing 117 form a water inlet cavity 1147, a backflow cavity 1146, and a water outlet cavity 1148. The water outlet cavity 1148 can communicate 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 on the top side of the backflow cavity 1146. The valve body upper housing 116 is an integral component, and / or the valve body lower housing 117 is an integral component. The valve housing 11 assembled by the valve body upper housing 116 and the valve body lower housing 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 housing 11, effectively preventing the valve housing 11 from breaking. When subjected to external impact, it can better resist deformation. Compared with the combination of independent pressure reducing valves and flow divider valves, such a flow divider 1 is less likely to loosen and separate, reducing the risk of leakage of the flow divider 1 and improving the sealing performance of the flow divider 1, thereby ensuring the sealing performance of the purification system is more stable during long-term use. It also simplifies the number of pipeline elements (such as valves, conduits, etc.) and pipe connections of the purification system, thereby facilitating the installation difficulty and subsequent maintenance difficulty of the purification system. At the same time, the integral molding technology can realize the manufacturing of the valve body through precise molds or machining processes, and can better control the dimensional accuracy and shape accuracy of the valve housing 11.

[0045] Further, please refer to Figure 1As 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 distance 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 distance 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.

[0046] Specifically, please refer 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.

[0047] Preferably, please refer 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.

[0048] In this embodiment, please refer to Figure 1 and Figure 2 It is shown that 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 to the water purifier. The pure water inlet 1143 is used to communicate with the water purifier to introduce the pure 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 pure water to the water tankless pipeline machine. The second water supply port 1145 is used to communicate with the faucet to deliver the pure 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.

[0049] 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.

[0050] Specifically, please refer to Figure 1 and Figure 2 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.

[0051] In addition, as Figure 10 shown, the valve shell 11 has a backflow guide portion 1171 located inside the water outlet cavity 1148, and the inside of the backflow guide portion 1171 is provided with a guide flow channel 1172 communicated with the backflow cavity 1146. Specifically, the backflow guide portion 1171 is arranged on the valve body lower shell 117, and the backflow guide portion 1171 extends towards 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 portion 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 1171 is separated from the backflow guide portion 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] Therefore, because the excess purified water can be returned when only the tankless pipeline machine is activated, the water purifier can avoid frequent adjustment of its working state due to sudden changes in the 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 return 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 return mechanism, the water pressure change can be buffered to some extent, reducing the pressure on the water purifier to frequently start and stop. In the case of simultaneous water use, the relative stability of the water flow distribution is maintained by the action of the flow splitting assembly 17. Without the flow splitting assembly 17, if the faucet and the tankless pipeline machine are used simultaneously and the water consumption of one suddenly changes (e.g., the faucet is suddenly closed), it can cause a large fluctuation in the internal water pressure of the water purifier, causing the water purifier to frequently adjust its working state. The flow splitting assembly 17 can maintain relatively stable water pressure and water flow distribution, reducing the situation of frequent start and stop of the water purifier caused by changes in external water use.

[0057] In related technologies, the overflow holes can elastically stretch 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 increase in size as the pressure difference between the two sides of the flow splitting 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 splitting assembly 17 and delaying the resetting of the flow splitting 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.

[0058] Based on this, the embodiments of the present application provide a flow splitting assembly 17 to solve the problem in related technologies that the flow splitter 1 is limited by the deformation amount of the overflow holes, and the maximum and minimum flow range that can be adjusted is limited.

[0059] For details, please refer to Figure 2As shown, the shunt assembly 17 is provided with a flexible check portion 1721 provided with a flow regulating port 1722, which can control the opening size of the flow regulating port 1722 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, so as to adjust the increasing variable of the pure water flowing into the water outlet cavity 1148. The increasing variable here should be understood as a physical quantity that the volume flow of the pure water increases with the change of the opening size of the flow regulating port 1722 during the flow through the flow regulating port 1722. That is, the flexible check portion 1721 has elasticity. 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 flow regulating port 1722 of the flexible check portion 1721 can be opened, then the water outlet upper cavity 11482 will also be communicated with the water outlet lower cavity 11481 through the flow regulating port 1722, and the cross-sectional area of the flow regulating port 1722 will increase with the increase of the pressure difference, until the flow regulating port 1722 is opened to the maximum deformation state, then the opening size of the flow regulating port 1722 will change from zero to the maximum, so that the volume flow of the pure water passing through the flow regulating port 1722 (hereinafter referred to as flow) can increase from zero to the maximum, so that part of the pure water will also be supplemented into the water outlet upper cavity 11482 through the flow regulating port 1722. It can be understood that when the pressure difference decreases, the flow regulating port 1722 will be able to reduce in the deformation recovery, until it is completely closed, at this time, the pure water will hardly flow through the flow regulating port 1722.

[0060] 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 elastic deformation of the flexible check portion 1721, thereby solving the problem that the maximum and minimum flow range that can be adjusted by the existing shunt 1 is limited due to the deformation variable of the overflow hole. Moreover, once the opening of the flow regulating port 1722 is adjusted, the flow of the pure water is relatively stable. Compared with only setting an expandable overflow hole, the risk of being blocked can be reduced during long-term use, 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.

[0061] It should be noted that the above-mentioned overflow hole capable of elastic expansion cooperates with the flexible check portion 1721, that is, the overflow hole and the flexible check portion 1721 are simultaneously provided on the shunt assembly 17.

[0062] Next, the specific structure of the above-mentioned shunt assembly 17 will be described in detail in combination with the drawings.

[0063] For details, please refer to Figure 10As shown, the shunt assembly 17 includes a shunt balance membrane 172 and a balance spring 171, the shunt balance membrane 172 is detachably connected between the valve upper shell 116 and the valve lower shell 117, and the valve upper shell 116 and the shunt balance membrane 172 cooperate to form the upper water outlet cavity 11482, the valve lower shell 117 and the shunt balance membrane 172 cooperate to form the lower water outlet cavity 11481, and the balance spring 171 is arranged between the shunt balance membrane 172 and the inner cavity wall of the upper water outlet cavity 11482.

[0064] Wherein, please see Figures 1 to 7 The shunt balance membrane 172 is made of elastic material (such as silica gel, rubber and the like), and the shunt balance membrane 172 is provided with a membrane through hole 1724, and the flow hole is the membrane through hole 1724, and at this time, the flow hole can also be elastically stretched. Further, the flexible check portion 1721 is arranged on the shunt balance membrane 172, and the flexible check portion 1721 cooperates with the flow hole to achieve more accurate flow control. When the flow demand of pure water is small, a small pressure difference can cause the flow hole to deform, which plays a role in fine adjustment of flow, and improves the adjustment accuracy of the shunt assembly 17 and the shunt device 1. When the flow demand of pure water is large, the flexible check portion 1721 can deform under the action of a large pressure difference, allowing a large amount of pure water to pass. This combination is equivalent to a multi-stage adjustment system, which can accurately adjust the flow through the shunt device 1 according to different working conditions (such as different water speeds of the tankless pipeline machine), and very effectively reduces the probability of frequent start and stop of the water purifier. At the same time, through the cooperation of the flow hole on the shunt balance membrane 172 and the flexible check portion 1721, the pressure balance on both sides of the shunt assembly 17 can be better maintained. That is, they can flexibly adjust their own state according to the size of the pressure difference on both sides, so that the distribution of pure water in the water outlet cavity 1148 is more stable, which helps to improve the reliability and service life of the shunt device 1, and reduces the damage to its components and system failure caused by pressure imbalance.

[0065] Thus, when the water consumption of the pipeline machine without a water tank is large, the pressure on the side of the shunt balance 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 balance membrane 172 will elastically deform towards the side of the first water inlet 1144 and compress the balance spring 171. When the water consumption of the pipeline machine without a water tank decreases, the pressure difference between the two sides of the shunt balance membrane 172 decreases, and the first water inlet 1144 has almost no pure water flow, meaning that there is no corresponding pressure due to the flow of pure water. At this time, the state of the two sides of the shunt balance membrane 172 returns to the initial balanced state. Under the action of the elastic deformation of the shunt balance membrane 172 itself and the elastic deformation of the balance spring 171, the side of the shunt balance membrane 172 away from the first water inlet 1144 deforms and recovers until the shunt balance membrane 172 abuts against the return guide portion 1171 to seal the guide flow channel 1172. Such an arrangement has the following unexpected effects:

[0066] 1. When the water consumption of the pipeline machine without a water tank is large, the pressure on the side of the shunt balance 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 balance membrane 172 will elastically deform towards the side of the first water inlet 1144 and compress the balance spring 171. At this time, the balance spring 171 acts as a buffer to absorb part of the pressure, preventing the shunt balance membrane 172 from being damaged due to excessive instantaneous pressure. When the water consumption of the pipeline machine without a water tank decreases, the pressure difference between the two sides of the shunt balance membrane 172 decreases. Since the balance spring 171 stores elastic potential energy after being compressed, the balance spring 171 releases the elastic potential energy to help the side of the shunt balance membrane 172 away from the first water inlet 1144 deform and recover.

[0067] 2. The elastic properties of the shunt balance membrane 172 can automatically adjust the size of the overflow hole according to the change in pressure difference. The balance spring 171 cooperates with the shunt balance membrane 172 to more finely control the deformation degree of the shunt balance membrane 172, thereby improving the shunt accuracy of the shunt device 1. For example, when the pressure difference changes slightly, the slight deformation of the shunt balance membrane 172 and the slight expansion of the balance spring 171 work together to more accurately regulate the amount of pure water flowing, thereby better achieving the function of automatically maintaining the pressure difference between the two sides of the shunt balance membrane 172.

[0068] 3. During the entire use of the tankless water dispenser, the water consumption is dynamically changing. The balance spring 171 and the diversion balance membrane 172 work together to effectively regulate the internal pressure balance of the water dispenser under different water usage conditions. This cooperation allows the diverter 1 to adapt to complex and changing operating conditions, reducing system failures caused by factors such as sudden pressure changes, enhancing the stability and reliability of the system, and extending the service life of the diverter 1. Furthermore, when the water consumption of the tankless water dispenser changes rapidly, the synergistic effect of the balance spring 171 and the diversion balance membrane 172 allows the diverter 1 to respond quickly. For example, when the water consumption of the tankless water dispenser suddenly increases, the balance spring 171 can quickly buffer the deformation of the diversion balance membrane 172, causing the flexible check valve 1721 to expand rapidly and increase the water flow. Conversely, when the water consumption of the tankless water dispenser suddenly decreases, both mechanisms can promptly reset the diversion balance membrane 172, reducing the flow of purified water, thereby optimizing the dynamic response capability of the diversion process.

[0069] It should be further explained that, please refer to the specific details. Figure 7 As shown, the aforementioned flexible check valve 1721 has a duckbill-shaped structure. A duckbill cavity 1723 is provided inside the flexible check valve 1721. The duckbill cavity 1723 passes through the diversion balancing membrane 172, and a duckbill opening is formed on the side of the diversion balancing membrane 172 facing away from the flexible check valve 1721. For details, please refer to... Figures 3 to 7 The flexible check valve 1721 includes a duckbill-shaped deformation portion 17211 and a base 17212 fixedly connected to the diversion balance membrane 172. The duckbill-shaped deformation portion 17211, the base 17212, and the diversion balance membrane 172 are integrally formed to facilitate processing and manufacturing, and to ensure the integrity of the diversion balance membrane 172, so that the diversion balance membrane 172 has good comprehensive performance (such as elasticity). The duckbill-shaped deformation portion 17211 protrudes from the base 17212 toward the upper outlet cavity 11482, and in the protrusion direction, the cross-sectional area of ​​the duckbill-shaped deformation portion 17211 on the side away from the diversion balance membrane 172 is smaller than the cross-sectional area on the side closer to the diversion balance membrane 172. Preferably, the cross-sectional area of ​​the duckbill deformation portion 17211 gradually decreases along the convex direction. The cross-section here is parallel to the large surface of the diversion balance membrane 172. The large surface of the diversion balance membrane 172 is the side with the largest area in the diversion balance membrane 172. The flow regulating port 1722 is located at the end of the duckbill deformation portion 17211 away from the diversion balance membrane 172, and the duckbill cavity 1723 is connected to the flow regulating port 1722.

[0070] As a preferred embodiment, please refer to the following for details. Figure 2 , Figure 3 , Figure 4 and Figure 7As shown, the shunt assembly 17 further comprises a diaphragm top cover 173, and the diaphragm top cover 173 is provided with a top cover through hole 1731, and the top cover through hole 1731 is communicated with the diaphragm through hole 1724, at this time, the top cover through hole 1731 and the diaphragm through hole 1724 constitute the overflow hole, and the diaphragm top cover 173 is arranged on the side of the shunt balance diaphragm 172 close to the first water inlet 1144, and the flexible check portion 1721 protrudes towards the diaphragm top cover 173 and penetrates the diaphragm top cover 173, that is, as shown in Figure 3 and Figure 4 As shown, the diaphragm top cover 173 is provided with a top cover through hole 1732, and the duckbill-shaped deformation portion 17211 of the flexible check portion 1721 penetrates the top cover through hole 1732 and protrudes out of the top cover through hole 1732 towards the water outlet upper cavity 11482, one end of the balance spring 171 abuts against the inner cavity wall of the water 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 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.

[0071] Further, as shown in Figure 2 The shunt assembly 17 is provided with a stop limiting portion 1733 protruding towards the side of the first water inlet 1144, and when the shunt assembly 17 moves relatively towards the side of the first water inlet 1144, 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 the condition of a large pressure difference, and a reliable mechanical limiting is formed, which effectively limits 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.

[0072] Preferably, as shown in Figure 3 , Figure 4 and Figure 7As shown, the stop limiting portion 1733 is arranged on the diaphragm top cover 173, and is preferably integrally formed with the diaphragm top cover 173. The stop limiting portion 1733 can withstand the impact force generated by the collision with the inner wall of the water outlet upper cavity 11482. Because the diaphragm top cover 173 has good structural strength, it can ensure that the stop limiting portion 1733 will not easily deform or be damaged during frequent displacement and collision, thereby better maintaining the stability and accuracy of the entire flow divider 1. In other embodiments, the stop limiting portion 1733 can also be arranged on the flow balance diaphragm 172.

[0073] The unexpected effect is that, as Figures 3 to 7 shown, the stop limiting portion 1733 is located outside the balance spring 171, and is arranged along the circumference of the balance spring 171 to constrain the end of the balance spring 171 inside the stop limiting portion 1733, thereby ensuring the stability of the balance spring 171 during deformation. It should be noted that the inner diameter of the stop limiting portion 1733 can be selected to match the outer diameter of the balance spring 171, or the inner diameter of the stop limiting portion 1733 can be larger than the outer diameter of the balance spring 171. In addition, the diaphragm top cover 173 can also be provided with a spring limiting column 1734 protruding towards the side of the first water inlet 1144, and the end of the balance spring 171 is sleeved on the spring limiting column 1734. In this way, the spring limiting column 1734 can cooperate with the stop limiting portion 1733 to achieve the purpose of double limiting of the balance spring 171. In addition, the spring limiting column 1734 can also quickly position the balance spring 171 during assembly, thereby improving the assembly efficiency.

[0074] Further, as shown in Figure 3 , the stop limiting portion 1733 is provided with an avoidance opening 1735 corresponding to the flexible check portion 1721. As shown in Figure 6 , the avoidance opening 1735 preferably penetrates the stop limiting portion 1733 along the protruding direction of the stop limiting portion 1733, so that the stop limiting portion 1733 forms two arc-shaped stop portions arranged opposite to each other. The number of flexible check portions 1721 is two, and each flexible check portion 1721 is located between the two stop portions. Such an arrangement has the following unexpected technical effects:

[0075] 1. The avoidance opening 1735 provides space for the flexible check portion 1721, which not only allows the flexible check portion 1721 to normally protrude towards the diaphragm top cover 173 and be arranged thereon, but also ensures that each flexible check portion 1721 can deform in a limited space according to the water flow pressure, thereby flexibly adjusting the water flow distribution.

[0076] 2、In the role of the avoidance port 1735, the flexible check portion 1721 on the membrane top cover 173 and the shunt balance membrane 172 can avoid mutual extrusion and friction in the working process, effectively reducing the interference and wear between the flexible check portion 1721 and the stop limiting portion 1733, thereby improving the service life of the shunt assembly 17. The reliability and durability of the shunt balance membrane 172 and the shunt assembly 17 are improved.

[0077] 3、The number of flexible check portions 1721 is configured as two, which can work cooperatively in the face of different water flow pressures and flow rates. For example, when the water flow impacts the shunt balance membrane 172, if there is only one flexible check portion 1721, it may be deformed to one side due to uneven impact of the water flow, resulting in unstable shunting. The two oppositely distributed flexible check portions 1721 can balance such impact force. When one side of the flexible check portion 1721 has a tendency to open due to a larger water flow pressure, the other side of the flexible check portion 1721 can make corresponding adjustments according to the pressure difference, thereby maintaining the stability of shunting, making the water flow from the first water supply port 1144 more uniform and stable.

[0078] 4、Under the action of the avoidance port 1735, when the stop limiting portion 1733 abuts against the inner wall of the water outlet upper cavity 11482, it can also maintain the pure water flowing through the avoidance port 1735 to the first water supply port 1144, 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, thereby preventing sudden changes in water flow pressure and ensuring the use stability and reliability of the shunt 1 and the pure drinking system.

[0079] Considering that the stop limiting portion 1733 abuts against the inner wall of the water outlet upper cavity 11482, the water outlet of the first water supply port 1144 is relatively large, i.e., the demand for pure water of the tankless pipeline machine is relatively large, in order to further ensure the supply of pure water, the stop limiting portion 1733 is provided with a water passing gap 1736, i.e., each stop position of the stop limiting portion 1733 is provided with a water passing gap 1736 near the first water supply port 1144 end, the shape and size of the water passing gap 1736 are not limited in this embodiment, which can be adjusted according to design requirements and structural design, then part of the pure water can also flow to the first water supply port 1144 through the water passing gap 1736, thereby ensuring sufficient pure water flowing to the first water supply port 1144 and supplying the tankless pipeline machine.

[0080] Of course, it should also be noted that in addition to the stop limiting portion 1733 on the shunt assembly 17 abutting against the inner wall of the water outlet upper cavity 11482, the specific Figure 10As shown, the inner cavity wall of the water outlet upper cavity 11482 is protruded to form a stop boss 1161 on the side facing the shunt assembly 17, specifically, the stop boss 1161 is protruded on the side of the inner cavity wall of the water outlet upper cavity 11482 facing the shunt assembly 17, and the stop boss 1161 is preferably integrally formed with the valve body upper shell 116 to facilitate production. The inside of the stop boss 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 boss 1161.

[0081] On the one hand, the stop boss 1161 cooperates with the stop limiting portion 1733 on the diaphragm top cover 173 to more accurately limit the deformation degree of the shunt balance diaphragm 172. When the shunt balance diaphragm 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 boss 1161, thereby further preventing the shunt balance diaphragm 172 from deforming excessively and better ensuring that the shunt balance diaphragm 172 works within a safe range. On the other hand, the purified 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 flow to the target outlet, avoiding water flow disorder, thereby improving the working efficiency and accuracy of the shunt device 1.

[0082] Preferably, specifically according to Figure 10 As shown, the flow channel inner wall of the first water supply channel 1162 is protruded to form a spring force body 1163, and the spring force body 1163 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, and 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. For example, Figure 2 As shown, the end of the balance spring 171 is inserted into the first water supply channel 1162, and the end of the balance spring 171 abuts against the spring force 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 work, that is, the end of the balance spring 171 abuts against the spring force body 1163, and the circumferential side of the balance spring 171 can contact the flow channel inner wall of the first water supply channel 1162, which well avoids the vibration or slight displacement of the balance spring 171 during work, thereby better ensuring that the balance spring 171 can normally play its balancing and adjusting functions, and more accurately transmitting force, ensuring and improving the shunt accuracy of the shunt device 1.

[0083] 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 10The first water supply channel 1162 is used for connecting the port of the water outlet upper cavity 11482, and the port is a second flow guide port. A positioning guide portion 1164 is arranged on the second flow guide port. The positioning guide portion 1164 is connected to the inner wall of the flow channel of the first water supply channel 1162 in a direction along the central axis of the first water supply channel 1162. During assembly, the end portion of the balance spring 171 is only required to be abutted to the positioning guide portion 1164. Under the guidance of the positioning guide portion 1164, the balance spring 171 will slide into the first water supply channel 1162 by itself, so as to achieve the purpose of self-positioning, and improve the assembly efficiency and assembly convenience of the balance spring 171.

[0084] As another preferred mode of the embodiment, specifically, please combine Figure 3 , Figure 4 and Figure 5 It can be understood that when the shunt assembly 17 is not configured with the diaphragm top cover 173, the base through hole 1741 and the diaphragm through hole 1724 constitute the overflow hole. Alternatively, when the shunt assembly 17 is configured with the diaphragm top cover 173, the shunt balance film 172 is clamped between the diaphragm top cover 173 and the diaphragm base 174, and the top cover through hole 1731, the diaphragm through hole 1724 and the base through hole 1741 constitute the overflow hole. The diaphragm base 174 is arranged on the side of the shunt balance film 172 away from the first water inlet 1144. In this way, when the flow of pure water flowing out of the first water inlet 1144 suddenly decreases, if the water inflow of the water purifier cannot be adjusted in time, the pressure of the water outlet upper cavity 11482 will quickly rise. In this case, the diaphragm base 174 can provide strong support for the shunt balance film 172. The diaphragm base 174 has a certain structural strength. Due to the support of the diaphragm base 174, the shunt balance film 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, and blockage or other faults caused by excessive deformation of the shunt balance film 172 are avoided. The continuous and stable operation of the water purifier under different working conditions is ensured, the working efficiency and service life of the water purifier are effectively improved, and a more reliable water purification experience is provided for the user.

[0085] It can be understood that the pressure difference formed by the pure water inlet 1143, the first water inlet 1144 and the second water inlet 1145 is equivalent to the difference between the pressure on the side of the diaphragm top 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 film 172.

[0086] Further, specifically, please combine Figures 1 to 4As shown, the diaphragm base 174 is further provided with a base avoiding hole 1742, the size of the base avoiding hole 1742 is greater than the diameter of the reflux guide part 1171, the reflux 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 reflux path of the pure 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 reflux of pure water to interfere with the normal water flow process. At the same time, the flexibility of the shunt balance membrane 172 improves the sealing between the shunt balance membrane 172 and the reflux guide part 1171.

[0087] It should be noted that, as Figure 7 As shown, the diaphragm base 174 is provided with a base water flow hole 1743 communicating with the flow adjusting hole 1722. That is, the base water flow hole 1743 on the diaphragm base 174 is correspondingly arranged and communicated with the duckbill cavity 1723 of the flexible check part 1721, ensuring that the pure water can pass through the base water flow hole 1743 and flow into the duckbill cavity 1723, and when the flow adjusting hole 1722 is opened, the pure water can flow into the water outlet upper cavity 11482 through the flow adjusting hole 1722.

[0088] As another preferred mode of the embodiment, specifically according to Figure 7 As shown, the diaphragm top cover 173 extends a flow guide extension body 175 towards the diaphragm through hole 1724, the flow guide extension body 175 is preferably integrally formed with the diaphragm top cover 173, and a water passing through hole 1751 is provided inside the flow guide extension body 175. Here, the through hole should be understood as the water passing through hole 1751 penetrating both ends of the flow guide extension body 175 along the extension direction of the flow guide extension body 175. The flow guide extension body 175 is inserted into the diaphragm through hole 1724, at this time, the top cover through hole 1731, the diaphragm through hole 1724, the base through hole 1741 and the water passing through hole 1751 constitute the flow hole. The pure water flows through the water passing through hole 1751, which is equivalent to the pure water flowing from the water outlet lower cavity 11481 through the base through hole 1741, the diaphragm through hole 1724 and the top cover through hole 1731 in sequence, and finally flowing into the water outlet upper cavity 11482.

[0089] In this way, the flow of pure water through the through hole 1751 is guided well, the flow of pure water in the through hole is more orderly and smooth, and the turbulence and energy loss of the water flow are reduced. Meanwhile, the close and orderly connection structure between the components enables the guide flow extension body 175 to be precisely inserted into the membrane hole 1724 of the shunt balance membrane 172 and the base hole 1741 of the membrane base 174 during assembly, thereby improving the positioning accuracy and assembly efficiency.

[0090] Further, as shown in Figures 4 to 7 The part of the guide flow extension body 175 that extends out of the base hole 1741 is provided with a buckle protrusion 1752, and the buckle protrusion 1752 is clamped on the membrane base 174, so as to realize the clamping connection between the membrane top cover 173 and the membrane base 174, so as to ensure that the shunt balance membrane 172 is clamped between the membrane top cover 173 and the membrane base 174, which is beneficial to the convenience and efficiency of disassembly and assembly, thereby facilitating the replacement of subsequent components. Moreover, the structure is simple, and the processing cost of each component is reduced. Of course, the membrane 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.

[0091] Preferably, the guide flow extension body 175 is located inside the top cover hole 1731, and a buffer gap is formed between the guide flow extension body 175 and the hole wall of the top cover hole 1731. This not only ensures that the assembly personnel can observe the membrane hole 1724 of the shunt balance membrane 172 through the buffer gap during assembly, which is convenient for assembly positioning and further improves the assembly efficiency. Meanwhile, the buffer gap serves as a space for deformation of the guide flow extension body 175 during clamping, thereby facilitating the clamping of the buckle protrusion 1752 on the membrane base 174 or the disassembly of the buckle protrusion 1752 from the membrane base 174.

[0092] It should be noted that in other embodiments, the guide flow extension body 175 can also be arranged to extend from the membrane base 174 towards the membrane hole 1724, and the guide flow extension body 175 sequentially passes through the base hole 1741, the membrane hole 1724, and the top cover hole 1731 and extends out of the top cover hole 1731. The part of the guide flow extension body 175 that extends out of the top cover hole 1731 is provided with a buckle protrusion 1752, and the buckle protrusion 1752 is clamped on the membrane top cover 173, which belongs to a conventional replacement mode of the above-mentioned preferred embodiment.

[0093] It should be noted that, as Figure 7As 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 hole 1741 to the diaphragm hole 1724 and then to the top cover hole 1731 according to the above description. 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 then 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 will decrease when the cross-sectional area increases while the flow remains basically 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.

[0094] 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 Figures 4 to 7 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 flexible check portion 1721 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.

[0095] 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 capability 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.

[0096] Further, as shown in Figures 4 to 7 , the groove wall of the deformation groove 1725 away from the flexible check portion 1721 is protrudingly formed with a diaphragm clamping portion 1726 outward, preferably, the diaphragm clamping portion 1726 is arranged on the groove wall of the deformation groove 1725 close to the slot side, and the diaphragm clamping portion 1726 is integrally formed with the shunt balance membrane 172, the diaphragm clamping portion 1726 is arranged along the groove length direction of the deformation groove 1725, and the diaphragm clamping portion 1726 is clamped between the valve upper shell 116 and the valve lower shell 117, thereby achieving the purpose that the shunt balance membrane 172 is detachably connected between the valve upper shell 116 and the valve lower shell 117, improving the assembly efficiency of the shunt device 1.

[0097] Specifically, as shown in Figure 10 , the valve lower shell 117 is provided with a diaphragm clamping groove 1173, and the diaphragm clamping portion 1726 is embedded in the inside of the diaphragm clamping groove 1173, so that the diaphragm clamping portion 1726 is more firmly connected between the valve upper shell 116 and the valve lower shell 117, improving the assembly of the shunt balance membrane 172 on the valve shell 11. Furthermore, the diaphragm clamping groove 1173 is arranged on the groove wall close to the flexible check portion 1721 and extends towards the inside of the deformation groove 1725, that is, the diaphragm clamping groove 1173 is accommodated in the inside of the deformation groove 1725 close to the flexible check portion 1721, 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 diaphragm clamping groove 1173 being arranged on the valve lower shell 117, the diaphragm clamping groove 1173 is arranged on the valve upper shell 116.

[0098] Preferably, as shown in Figure 10As 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.

[0099] In the pure drinking system, when the user starts or turns off the tankless pipeline machine, the flow rate of the pure water flowing through the shunt 1 will change sharply, thereby causing the 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 inventors also provide a preferred mode, please see Figure 1 and Figure 2 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.

[0100] 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 adjustment 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.

[0101] Preferably, as shown in Figure 10 Preferably, as shown in

[0102] In addition, the presence of the water flow buffer hole 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 buffer hole 181, a certain pressure difference will be formed on both sides of the water hammer absorbing piece 18, which plays a certain degree of adjustment. At the same time, due to the presence of the water flow buffer hole 181, the pure water will have a certain flow under the action of the pressure difference, which can alleviate the sharp rise of the pressure, making the pressure change more gentle, and further reducing the water hammer phenomenon.

[0103] It should be noted that the number, size and distribution of the water flow buffer hole 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 buffer hole 181, the pulse frequency of the pure water flow can also be changed. For example, when the water hammer phenomenon occurs, high-frequency pressure pulses will appear. The water flow buffer hole 181 is configured in a combination of large and small holes, wherein the large hole allows a larger flow of water to pass through, and the small hole has more restrictions on the water flow, so that the high-frequency pressure pulse can be converted into a relatively low-frequency pulse (i.e. the irregular pulse becomes more regular), and the low-frequency and regular pressure change has relatively small impact on the flow divider 1, thereby also helping to reduce the harm of water hammer.

[0104] Further, as shown in Figure 10 and Figure 11 , the water hammer absorbing piece 18 is provided with a positioning assembly hole 182 for inserting the backflow guide part 1171, and the hole diameter of the positioning assembly hole 182 is matched with the diameter of the backflow guide part 1171, so that the backflow guide part 1171 can be quickly and stably installed on the valve body lower shell 117 of the valve shell 11. In order to ensure that the water hammer absorbing piece 18 can be more stably installed on the valve body lower shell 117, and the stress between the water hammer absorbing piece 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 piece boss 1174, and the edge part of the water hammer absorbing piece 18 abuts against the absorbing piece boss 1174, which is simple in structure and convenient to disassemble and assemble, and is beneficial to subsequent maintenance and repair.

[0105] Of course, as shown in Figure 11 , the absorbing piece boss 1174 is protruded to form a limiting convex part 1175 towards one side of the flow dividing assembly 17, and the edge part of the water hammer absorbing piece 18 is provided with a limiting gap 183 for inserting the limiting convex part 1175. In this way, the limiting gap 183 and the limiting convex part 1175 cooperate to prevent the water hammer absorbing piece 18 from being deflected around the backflow guide part 1171, thereby more stably guiding the flow of pure water.

[0106] In some other embodiments, the water hammer absorber 18 can also be a piston type water hammer eliminator, or a diaphragm type water hammer eliminator, both of which are relatively mature existing technologies in the water hammer eliminator field, and their structures will not be described in detail here. Alternatively, the water hammer absorber 18 can also be a slow closing check valve.

[0107] As a preferred mode of the present embodiment, please refer to Figure 8 、 Figure 9 and Figure 10 for details. The water filter 19 is provided with a filtering hole 191 in the extension direction of the water inlet channel 1176, and a water passing gap is formed between the peripheral side wall of the water filter 19 and the inner side wall of the water inlet channel 1176. The peripheral side wall of the water filter 19 is provided with a water discharge opening 192 connected to the water passing gap, and the opening size of the water discharge opening 192 is larger than the hole diameter of the filtering hole 191.

[0108] In this way, the filtering hole 191 provided on the water filter 19 can further filter the water flow in the direction of the pure water flow, preventing small particles from flowing into the water outlet chamber 1148 and the tankless pipeline machine when the filter core of the water purifier is close to the end of its service life, thereby ensuring and improving the purity of the pure water supplied to the tankless pipeline machine and the faucet, and improving the taste and quality of the drinking water.

[0109] More importantly, when the pure water passes through the filtering hole 191 of the water filter 19, the water flow will generate a certain resistance when passing through the filtering hole 191 due to the relatively small hole diameter of the filtering hole 191. The presence of the water discharge opening 192 can play a diversion role. The opening size of the water discharge opening 192 is larger than the hole diameter of the filtering hole 191, and a part of the water can flow through the water discharge opening 192 and the water passing gap, sharing part of the water flow, so that the water flow rate through the filtering hole 191 will not be too high, thereby reducing the water resistance of this part. At the same time, the presence of the water discharge opening 192 and the water passing gap also helps to balance the pressure in the water inlet channel 1176, and the water can be redistributed between the filtering hole 191 and the water discharge opening 192, so that the pressure distribution in the entire water inlet channel 1176 is more uniform, and the water resistance of the water inlet channel 1176 and the entire water shunt 1 is also reduced.

[0110] Preferably, please refer to Figure 8 、 Figure 9 and Figure 10The water filtering part 19 comprises a body fastening part 193 and a body water filtering part 194 fixedly connected with the body fastening part 193, and the fixed connection is preferably one-piece forming, facilitating production and manufacture. The water discharging through hole 192 and the filtering hole 191 are both arranged on the body water filtering part 194. Specifically, the body water filtering part 194 has a water filtering part bottom wall and a water filtering part side wall extending along the circumferential side of the water filtering part bottom wall, and the water filtering part bottom wall and the water filtering part side wall cooperatively enclose a filtering cavity. The filtering cavity has a filter cavity opening arranged opposite to the water filtering part bottom wall. The filtering hole 191 is arranged on the water filtering part bottom wall, the water discharging through hole 192 is arranged on the water filtering part side wall, the body fastening part 193 is arranged on one side of the water filtering part side wall close to the filter cavity opening, and the body fastening part 193 is arranged extending along the circumference of the filter cavity opening. The body fastening part 193 is formed protruding outwardly from the water filtering part side wall, so that when the water filtering part 19 is inserted into the water inlet flow channel 1176, the body fastening part 193 is detachably connected to the valve body lower shell 117 of the valve shell 11, and the body water filtering part 194 and the flow channel inner side wall of the water inlet flow channel 1176 automatically form a water passing gap.

[0111] It should be noted that the water discharging through hole 192 is a water discharging group, which comprises a plurality of water discharging holes arranged along the circumference of the body water filtering part 194, and the diameter of each water discharging hole is larger than the diameter of the filtering hole 191. The water discharging group can be configured as one group, or as a plurality of groups. The plurality of water discharging groups are arranged uniformly along the extension direction of the water inlet flow channel 1176. Alternatively, as shown in Figure 9 , the water discharging through hole 192 can also be in the shape of a strip hole, and the water discharging through hole 192 is arranged extending along the circumferential part of the body water filtering part 194. The number of the water discharging through hole 192 can be one or a plurality of, and the plurality of water discharging through holes 192 are arranged and distributed along the extension direction of the water inlet flow channel 1176, and preferably, the adjacent two water discharging through holes 192 are arranged staggered.

[0112] Preferably, as shown in Figure 8As shown, the filter buckle body 1177 is arranged on the inner side wall of the water inlet channel 1176, and extends along the circumferential direction of the water inlet channel 1176. The body fastening part 193 is clamped with the filter buckle body 1177, and the filter buckle body 1177 extends along the extension direction of the water inlet channel 1176. Further, the filter buckle body 1177 is provided with a fastening clamping groove, and the body fastening part 193 is provided with a fastening protrusion 195, and the fastening clamping groove is connected with the fastening protrusion 195 in a plug-in manner. In this way, the filter element 19 is effectively and stably connected to the inside of the water inlet channel 1176, and the filter element 19 will not be easily displaced under the long-term impact of the water flow, so as to ensure that the filter hole 191 and the drain opening 192 can normally play a role and maintain the stability of the filtering function. At the same time, the filter buckle body 1177 is clamped in the filter clamping groove, and the fastening clamping groove is connected with the fastening protrusion 195 in a plug-in manner, so that the installation of the filter element 19 is more convenient. When assembling the flow divider 1, the worker only needs to align the filter element 19 with the water inlet channel 1176 and clamp it to complete the installation, which is convenient for later disassembly, cleaning and replacement and maintenance. It should be noted that, in addition to the above-mentioned mode that the fastening clamping groove is arranged on the filter buckle body 1177 and the fastening protrusion 195 is arranged on the body fastening part 193, the fastening clamping groove can also be arranged on the body fastening part 193, and the fastening protrusion 195 is correspondingly arranged on the filter buckle body 1177.

[0113] As a preferred mode of the present embodiment, the flow divider 1 further comprises a water resistance element for increasing the resistance of the water flow. The valve body lower shell 117 of the valve shell 11 is provided with a second water supply channel 1178, and the second water supply opening 1145 is connected with the water outlet cavity 1148 through the second water supply channel 1178. The water resistance element is arranged in the second water supply channel 1178, and the water resistance element is detachably connected with the valve shell 11. In this way, pressure fluctuations caused by water flow impact can be effectively avoided. When the faucet is suddenly opened or closed, the sharp change of water flow speed will cause water hammer phenomenon, resulting in instantaneous increase of pressure in the second water supply channel 1178. The resistance of the water resistance element to the water flow can slow down the sudden change of water flow speed, thereby buffering the pressure change. At the same time, the water resistance element can also play a certain role in preventing backflow. When the pressure in the second water supply channel 1178 suddenly decreases, backflow of water may occur. Since the water resistance element can increase the resistance of backflow, the possibility of backflow is reduced.

[0114] In the present embodiment, specific reference is made to Figure 8 and Figure 10As shown, the water passing support frame 1131 with the support water outlet 1134 is arranged on the valve body lower shell 117. Preferably, the water passing support frame 1131 is preferably arranged in two, and the two water passing support frames 1131 are staggered. The inner wall of the second water supply channel 1178 cooperates with the two water passing support frames 1131 to form four support water outlets 1134. The water passing support frame 1131 is arranged inside the second water supply channel 1178, and is preferably integrally formed with the valve body lower shell 117. The water resistance member abuts the water passing support frame 1131. Further, the side of the water passing support frame 1131 facing the water outlet cavity 1148 is provided with a support positioning portion 1132. The water resistance member can be provided with a water resistance insertion opening for inserting the support positioning portion 1132, so that the water resistance member can be stably mounted and fixed on the support positioning portion 1132.

[0115] Preferably, as shown in particular in Figure 8 , Figure 10 and Figure 11 , the inner wall of the flow channel of the second water supply channel 1178 is provided with a bearing protrusion 1133. The bearing protrusion 1133 extends along the extension direction of the second water supply channel 1178. The water resistance member abuts the bearing protrusion 1133, so that the water resistance member is more stably mounted inside the second water supply channel 1178. Further, the cross-sectional area of the side of the bearing protrusion 1133 away from the second water outlet 1145 is smaller than the cross-sectional area of the side of the bearing protrusion 1133 close to the second water outlet 1145. Preferably, the cross-sectional area of the bearing protrusion 1133 gradually increases from the inner wall of the flow channel of the second water supply channel 1178 towards the side close to the second water outlet 1145.

[0116] In this way, during the molding process of manufacturing the valve body lower shell 117, the draft of the bearing protrusion 1133 makes it easier to separate the mold and the valve body lower shell 117, and may cause defects such as tearing and deformation of the bearing protrusion 1133 during demolding, affecting product quality. At the same time, due to the gradually increasing cross-sectional area of the bearing protrusion 1133, when the water resistance member is installed, it is equivalent to having a guiding effect. The water resistance member can more easily slide into the correct installation position along the direction of the draft, which helps the installation of the water resistance member and makes the water resistance member more stable after installation. Because the water resistance member is installed, the part of the bearing protrusion 1133 with a larger cross-sectional area can limit the movement of the water resistance member in the flow channel direction to some extent. For example, when the water flow impacts the water resistance member, the water resistance member will not easily displace in the flow channel direction, ensuring that the water resistance member stably and normally exerts resistance to the water flow. In addition, the bearing protrusion 1133 can better guide the water flow of pure water. Due to the gradually increasing cross-sectional area of the bearing protrusion 1133, the water flow will change direction more smoothly when passing through the bearing protrusion 1133, reducing the degree of turbulence of the water flow, thereby improving the stability and uniformity of the water flow.

[0117] As a preferred mode of the present embodiment, the water resistance member includes a water resistance member body, a plurality of flow-limiting water resistance holes are arranged on the water resistance member body, each flow-limiting water resistance hole is communicated with the support water outlet 1134, and the water resistance member body is connected with the above-mentioned bearing protrusion 1133. In this way, when the purified water passes through these flow-limiting water resistance holes, the water and air are fully mixed due to the resistance of the flow-limiting water resistance holes, which can not only reduce the flow rate of the water, but also make the water flow out in a foamy state, and the plurality of flow-limiting water resistance holes communicated with the support water outlet 1134 can also make the water flowing out of the water outlet more evenly dispersed, achieving water saving while preventing water splashing. In some embodiments, the water resistance member can be selected as a one-way valve assembly, and can also be selected as a throttle valve, and can also be selected as a bubbler.

[0118] The unexpected effect is that, as shown in Figure 10 When the water hammer absorbing member 18 is installed to the water outlet lower cavity 11481, the water hammer absorbing member 18 will better restrict the water resistance member completely in the second water supply channel 1178, ensuring the stability of the installation of the water resistance member. At the same time, since the water hammer absorbing member 18 is installed upstream of the water flow of the water resistance member, it can absorb and buffer before the water hammer pressure wave reaches the water resistance member. This can protect the water resistance member from being damaged due to bearing too high water hammer pressure, ensure that the water resistance member can normally play its functions of limiting water flow, adjusting pressure, etc., more accurately control the water flow according to the designed flow-limiting water resistance holes and other structures, so as to provide more stable water inlet conditions for the subsequent faucet or other water outlet equipment, reduce the impact of water hammer on the faucet, thereby prolonging the service life of the faucet and reducing the frequency of maintenance and replacement.

[0119] It should be noted that, in order to reduce the vibration of the water resistance member during the water resistance treatment process, the circumferential wall of the water resistance member body can also be provided with a bearing insertion slot for inserting and connecting the bearing protrusion 1133. In addition, the aperture of the flow-limiting water resistance hole is between 0.5-1.5mm to provide a relatively stable water flow resistance, thereby avoiding the risk of blockage during long-term use.

[0120] As a preferred mode of the embodiment, the flow distributor 1 further comprises a water inlet filter arranged at the raw water inlet 1141, wherein the water inlet filter is preferably a filter screen. In this way, it can effectively prevent some large-particle impurities (such as silt, etc.) possibly contained in tap water from flowing into the water inlet cavity 1147, achieving the purpose of preliminary filtration, avoiding the risk of damage to the pressure regulating assembly 16 inside the flow distributor 1 and the risk of pressure stabilization failure of the flow distributor 1, and also reducing the total amount of impurities entering the water purifier, to some extent, prolonging the service life of the filter element of the water purifier. In combination with the water filter 19 arranged at the purified water inlet 1143, not only the purpose of double filtration of the flow distributor 1 is achieved, that is, although the purified water filtered by the water purifier has removed most of the impurities, bacteria and harmful substances, it may still be contaminated during the delivery process, such as particle impurities generated by pipeline residues or aging. At this time, the water filter 19 can further intercept these impurities to ensure that the quality of the purified water flowing to each water terminal is more pure. At the same time, the triple filtration effect of the water source of the water purification system is achieved, thereby effectively ensuring that the water purification system has good water quality and provides safer drinking water for users.

[0121] The above is the explanation and description of the flow distributor proposed in the embodiments of the present application, and since the water purification 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.
