Description

[0002] In the related technology, when the water supply is greater than the demand, the excess pure water has nowhere to overflow. Once the pressure at the water outlet of the pure water machine is higher than the pressure at which the pressure switch of the pure water machine disconnects, the pure water machine will be shut down. Then the water pumping operation will be performed. The pressure at the water outlet of the pure water machine is lower than the pressure at which the pressure switch of the pure water machine disconnects, and the pure water machine will start working again.

[0051] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0052] In order to make the objectives, technical solutions and advantages of the present application clearer, the following part will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.

[0053] When the following description refers 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 embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0054] In the description of the present application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not 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 according to the specific circumstances. In addition, in the description of the present application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0055] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0056] On the one hand, the present application proposes a drinking water purification system, which includes a water purifier, a 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 reaches the standard that is safe for drinking or meets specific usage requirements. The tankless pipeline machine is used to instantly heat or cool the purified water source, so that users can accurately obtain drinking water and meet the different drinking water temperature requirements of users. It should be noted that the water purifier, the tankless pipeline machine and the faucet are all relatively mature existing technologies in this field, and the present application has not made significant improvements to the water purifier, the tankless pipeline machine and the faucet. Therefore, the present application does not elaborate on the structure of the water purifier, the tankless pipeline machine and the faucet, nor does it limit the types and models of the water purifier and the tankless pipeline machine.

[0057] Considering that the purified water source is distributed to the tankless pipeline machine and the faucet at the same time to improve the water utilization efficiency, the rear end of the water outlet of the water purifier is usually equipped with a diverter valve, and the water inlet end of the tankless pipeline machine and the water inlet of the faucet are both connected to the diverter valve. When the user needs to take direct drinking water with the appropriate temperature, such as drinking ice water at 5℃~15℃ in the hot summer, or taking warm water at 40℃~50℃ to make milk powder, or taking hot water at 90℃~99℃ to make tea, the user can turn on the tankless pipeline machine to take it. When the user needs to take domestic water to wash tableware, wash vegetables and fruits, or wash clothes, the user can turn on the faucet to take it.

[0058] For details, please refer to Figure 1 and Figure 2 As shown, the diverter 1 includes a valve housing 11, which includes a valve body upper shell 116 and a valve body lower shell 117 that are interconnected. The interconnection here should be understood as a detachable connection, such as a bolt connection, a snap connection, etc., to facilitate the production of the valve body upper shell 116 and the valve body lower shell 117, and can also effectively improve the assembly efficiency and reduce the difficulty of assembly. In this embodiment, the valve body upper shell 116 and the valve body lower shell 117 are configured with a water inlet chamber 1147, a reflux chamber 1146 and a water outlet chamber 1148. The water outlet chamber 1148 can be connected to the water inlet chamber 1147 through the reflux chamber 1146. The water inlet chamber 1147 and the water outlet chamber 1148 are preferably located on the top side of the reflux chamber 1146. The valve body upper shell 116 is an integrally formed component, and / or the valve body lower shell 117 is an integrally formed component. Then, the valve housing 11 after the valve body upper shell 116 and the valve body lower shell 117 are assembled is more stable and has a higher structural strength. In this way, when subjected to high-pressure fluid, the pressure can be evenly distributed in various parts of the valve housing 11, effectively preventing the valve housing 11 from rupturing. When subjected to external impact, it can better resist deformation. Compared with the combination of an independent pressure reducing valve and a diverter valve, such a diverter 1 is less likely to loosen or detach, reducing the risk of leakage of the diverter 1 and improving the sealing performance of the diverter 1, thereby ensuring that the sealing of the drinking water purification system is more stable during long-term use, and also simplifying the number of pipeline components (such as valves, conduits, etc.) and pipeline connections of the drinking water purification system, thereby helping to reduce the difficulty of installation and subsequent maintenance of the drinking water purification system. At the same time, the one-piece molding technology can realize the manufacture of the valve body through precise molds or processing techniques, and can also better control the dimensional accuracy and shape accuracy of the valve housing 11.

[0059] Further, please refer to Figure 1As shown, the diverter 1 also includes a pressure regulating assembly 16, which is arranged in the water inlet chamber 1147 to divide the water inlet chamber 1147 into an air chamber 1153 and a liquid chamber. Specifically, a pressure reducing chamber outlet 1151 is arranged on the valve housing 11, so that the liquid chamber can be connected to the reflux chamber 1146 through the pressure reducing chamber outlet 1151. Among them, the pressure regulating assembly 16 is provided with a water injection guide hole and a pressure regulating outlet connected to the liquid chamber. The pressure regulating assembly 16 and the valve body upper shell 116 cooperate to form an air chamber 1153 in the space enclosed. The inner wall of the air chamber 1153 is provided with a water injection conduit portion extending toward the inside of the air chamber 1153. The inside of the water injection conduit portion is provided with a water injection flow channel connected to the water supply pipeline, and the port of the water injection flow channel used to connect the liquid chamber is defined as a water passing port. The water injection conduit portion is inserted into the water injection guide hole, and the water injection flow channel of the water injection conduit portion is connected to the liquid chamber. Because the pressure regulating assembly 16 includes a pressure regulating execution end arranged inside the liquid chamber. According to the pressure difference formed between the pressure regulating water outlet and the water injection guide hole, the pressure regulating component 16 can produce relative displacement along the central axis of the water injection conduit portion to change the throttling distance between the water port and the pressure regulating execution end. In this way, as the outlet pressure changes, the pressure regulating component 16 automatically makes corresponding displacements to change the throttling distance between the water port and the pressure regulating execution end, thereby achieving the purpose of the diverter 1 adjusting the tap water supplied by the water supply pipe into stabilized water. This not only stabilizes the water pressure in the water supply pipe, but also reduces the water pressure entering the water purifier in advance, avoiding physical damage to the water purifier due to excessive water pressure. Of course, other pressure regulating components adapted to the present application can also be used as a replacement for the pressure regulating component 16.

[0060] Please refer to Figure 1 As shown, a one-way flow guide 13 is provided in the reflux chamber 1146 to prevent the pressure-stabilized water flowing through the liquid chamber from flowing back to the water outlet chamber 1148 after being pressure-stabilized, and to output the excess water flowing back from the water outlet chamber 1148 to the reflux chamber 1146 to the water purifier after merging with the pressure-stabilized water. This not only prevents the pressure-stabilized water in the liquid chamber from flowing back to the water outlet chamber 1148 after being pressure-stabilized, so as to ensure the quality of domestic water and direct drinking water. At the same time, the pressure of both the water outlet chamber 1148 and the liquid chamber is maintained, so that the water source flow in the water outlet chamber 1148, the liquid chamber and the reflux chamber 1146 can be carried out in the designed direction and pressure conditions, so as to achieve the stability of the diverter 1 and the drinking water purification system while simplifying the pipeline components and connections of the drinking water purification system.

[0061] Preferably, see Figure 1The one-way flow guide 13 includes a check body 131 and a mixing flow guide 132, wherein the check body 131 has an input port and an output port, and the check body 131 is used to control the water source to flow from the input port to the output port. It can be understood that the water source refers to the excess water that flows back from the water chamber 1148 toward the reflux chamber 1146. The mixing guide body 132 is provided with a flow guide channel inside. The mixing guide body 132 is provided with an extension part 133 having a liquid injection port 1331 protruding toward one side of the check body 131. The extension part 133 is extended along the circumferential part of the mixing guide body 132 and is provided at the end of the mixing guide body 132. The check body 131 is provided with an input port at one end thereof and abuts against the extension part 133 to form a mixing chamber. The liquid injection port 1331 can be aligned with the water inlet chamber 1147 and connected to the liquid chamber of the water inlet chamber 1147, thereby avoiding the problem of unstable water pressure caused by turbulence or eddy current caused by the obstruction of the pressure-stabilized water. The output port is connected to the mixing chamber, and the excess water flows through the check body 131 and is mixed with the pressure-stabilized water in the mixing chamber. After the excess water is mixed with the pressure-stabilized water, it is guided to the raw water outlet 1142 by the flow guide channel and transported to the water purifier. Of course, other one-way valves that can mix the excess water and the pressure-stabilized water and conduct one-way diversion can be used as a replacement for the one-way flow guide 13.

[0062] In this embodiment, please refer to Figure 1 and Figure 2 As shown, the diverter 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, wherein the raw water inlet 1141 is used to connect the water supply pipe to introduce tap water into the water inlet chamber 1147 of the valve housing 11, the raw water outlet 1142 is used to connect the water purifier to deliver the pressure-stabilized water that flows through the water inlet chamber 1147 and is pressure-stabilized to the water purifier, the pure water inlet 1143 is used to connect the water purifier to introduce the pure water purified by the water purifier, the first water supply port 1144 is used to connect the water tankless pipeline machine to deliver the pure water to the water tankless pipeline machine, and the second water supply port 1145 is used to connect the faucet to deliver the pure water to the faucet. Furthermore, the liquid cavity is connected to the raw water inlet 1141 through the water injection channel, the raw water outlet 1142 is connected to the reflux cavity 1146, and the pure water inlet 1143, the first water supply port 1144, and the second water supply port 1145 are all connected to the water outlet cavity 1148. Preferably, the raw water outlet 1142, the pure water inlet 1143, and the second water supply port 1145 are all arranged on the valve body lower shell 117, and the raw water inlet 1141 and the first water supply port 1144 are arranged on the valve body upper shell 116.

[0063] In the above, the diverter 1 can distribute the purified water after the water purifier is purified, that is, the purified water flows through the purified water inlet 1143 and enters the water outlet chamber 1148. When the tankless pipeline machine connected to the first water supply port 1144 is activated, the purified water can flow out from the first water supply port 1144 and be delivered to the tankless pipeline machine. When the faucet connected to the second water supply port 1145 is opened, the purified water can flow out from the second water supply port 1145 and be delivered to the faucet, so as to achieve the purpose of reasonably distributing purified water. Next, the specific structure involved in the diversion is explained in conjunction with the accompanying drawings.

[0064] Please refer to the Figure 1 and Figure 2 The diverter 1 also includes a diverter component 17, which is installed in the water outlet chamber 1148 of the valve housing 11, wherein the diverter component 17 is provided with a flow hole, which is used to guide the pure water flowing in from the pure water inlet 1143 to pass through the diverter component 17 and enter the water outlet chamber 1148. Furthermore, the diversion component 17 divides the water outlet chamber 1148 into a lower water outlet chamber 11481 and an upper water outlet chamber 11482. The above-mentioned pure water inlet 1143 and the second water supply port 1145 are both connected to the lower water outlet chamber 11481, and the upper water outlet chamber 11482 is connected to the first water supply port 1144. The upper water outlet chamber 11482 is connected to the lower water outlet chamber 11481 through a flow hole. At this time, after the pure water flows from the pure water inlet 1143 into the lower water outlet chamber 11481 for buffering and storage, another part of it will flow to the upper water outlet chamber 11482 through the flow hole, and finally flow out from the first water supply port 1144.

[0065] In addition, if Fig.10 As shown, the valve housing 11 has a reflux guide portion 1171 , which is located inside the water outlet cavity 1148 , and a guide flow channel 1172 communicating with the reflux cavity 1146 is disposed inside the reflux guide portion 1171 . Specifically, the reflux guide portion 1171 is arranged on the lower shell 117 of the valve body, and the reflux guide portion 1171 is extended toward the water outlet chamber 1148, wherein the guide channel 1172 extends to the port of the water outlet lower chamber 11481 and connects to the water outlet lower chamber 11481, and the diverter component 17 can abut the reflux guide portion 1171, and 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 diverter component 17 can generate a relative displacement toward the side of the first water supply port 1144, so that the diverter component 17 is separated from the reflux guide portion 1171, and then excessive pure water will be able to flow from the guide channel 1172 into the reflux chamber 1146 to form the above-mentioned excess water.

[0066] In this way, when the faucet is used alone, pure water will flow from the pure water inlet 1143 into the water outlet lower cavity 11481, and then flow out directly from the second water supply port 1145 from the water outlet lower cavity 11481. At this time, the diversion component 17 abuts against the reflux guide portion 1171 to seal the guide channel 1172, so that pure water will not flow back to the guide channel 1172.

[0067] When the water tankless pipeline machine uses water alone, pure water flows from the pure water inlet 1143 into the water outlet lower chamber 11481, flows through the flow hole and enters the water outlet upper chamber 11482, and finally flows out from the first water supply port 1144 to the water tankless pipeline machine. At this time, the pressure on the side of the diverter assembly 17 close to the first water supply port 1144 is less than the pressure on the side of the diverter assembly 17 facing away from the first water supply port 1144, that is, the water pressure formed by the pure 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 diverter assembly 17 can produce a relative displacement toward the first water supply port 1144, so that the diverter assembly 17 is separated from the reflux guide portion 1171, and the excess pure water flows back to the guide channel 1172. It can be understood that the water output of the first water supply port 1144 is determined by the water pump and the negative pressure valve of the water tankless pipeline machine.

[0068] When the tankless pipeline machine is turned off, the flow splitter assembly 17 will be reset toward the side of the reflux guide portion 1171, and the flow splitter assembly 17 will be re-contacted on the reflux guide portion 1171 to re-seal the guide channel 1172. Therefore, the flow splitter 1 can flexibly respond to the water flow distribution requirements when the tankless pipeline machine uses water alone, so that the purified water can reasonably handle the excess water while meeting the water needs of the tankless pipeline machine, without causing waste of water resources, and avoiding the risk of damaging the tankless pipeline machine due to excessive water pressure.

[0069] When the tankless pipeline machine and the faucet use water at the same time, after the pure water flows from the pure water inlet 1143 into the water outlet lower cavity 11481, a part of the pure water flows out from the second water supply port 1145 to the faucet, and the other part of the pure water enters the water outlet upper cavity 11482 through the flow hole and flows out from the first water supply port 1144 to the tankless pipeline machine. Due to the reduction in water pressure on the side of the second water supply port 1145, the pressure on the side of the diverter component 17 close to the first water supply port 1144 is not much different from the pressure on the side of the diverter component 17 facing away from the first water supply port 1144. At this time, the diverter component 17 abuts against the reflux guide part 1171, and the excess pure water will hardly flow to the guide channel 1172. In this way, the tankless pipeline machine and the faucet can use water normally, ensuring the stable operation of the entire drinking water purification system.

[0070] Therefore, because only the tankless pipeline machine is enabled, the excess pure water can flow back, which can prevent the water purifier from frequently adjusting its working state due to sudden changes in the water consumption of the tankless pipeline machine (such as changes in water pressure caused by frequent opening and closing of the tankless pipeline machine). For example, if there is no reflux mechanism, when the tankless pipeline machine is suddenly closed, the instantaneous change in water pressure may have an impact on the internal structure and working pressure of the water purifier, and with the reflux mechanism, it can buffer this water pressure change to a certain extent and reduce the pressure of frequent start and stop of the water purifier. In the case of simultaneous water use, a relatively stable water flow distribution state is maintained by the action of the diverter component 17. If there is no diverter component 17, and the faucet and the tankless pipeline machine are working at the same time, a sudden change in the water consumption of one party (such as the sudden closing of the faucet) may cause a large fluctuation in the water pressure inside the water purifier, causing the water purifier to frequently adjust its working state. The diverter component 17 can maintain a relatively stable water pressure and water flow distribution, reducing the frequent start and stop of the water purifier caused by changes in external water use.

[0071] In the related art, the above-mentioned flow holes can be elastically expanded and contracted, and the flow rate of pure water flowing through the flow holes can be adjusted by the slight deformation of these flow holes. That is, when the water consumption of the water tankless pipeline machine increases, the flow holes become larger as the pressure difference on both sides of the diversion component 17 increases, and the flow rate of pure water increases. When the water consumption of the water tankless pipeline machine decreases, the flow holes shrink under the action of their own rebound force, and the flow rate of pure water decreases, thereby automatically maintaining the pressure difference on both sides of the diversion component 17 and delaying the resetting of the diversion component 17. However, since the deformation of the flow hole is limited, the maximum and minimum flow ranges that it can adjust will also be greatly limited. For example, when the water consumption of the water terminal varies greatly, it is limited by the shape and size of the flow hole and the deformation, and the flow hole with a small deformation alone will not be able to meet the actual flow regulation needs.

[0072] Based on this, an embodiment of the present application provides a flow splitter assembly 17, which aims to solve the problem in the related art that the flow splitter 1 is limited by the deformation of the flow hole, so that the maximum and minimum flow ranges that can be adjusted are limited.

[0073] Please refer to Figure 2As shown, the flow dividing component 17 has a flexible check portion 1721 provided with a flow regulating port 1722, and the flexible check portion 1721 can control the opening and closing size of its 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 amount of increase of the pure water flowing into the water outlet cavity 1148. The amount of increase here should be understood as the physical quantity that the volume flow of the pure water increases as the opening and closing size of the flow regulating port 1722 changes during the process of the pure water flowing through the flow regulating port 1722. That is, the flexible check portion 1721 is elastic, and when the water output from 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, and the flow regulating port 1722 of the flexible check portion 1721 can be opened, then the water outlet upper chamber 11482 will also be connected to the water outlet lower chamber 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 it opens to the maximum deformation state of the flow regulating port 1722, then the opening and closing size of the flow regulating port 1722 will change from zero to the maximum, so that the volume flow rate (hereinafter referred to as flow rate) of pure water that can pass through the flow regulating port 1722 is increased from zero to the maximum, so that part of the pure water will also be replenished into the water outlet upper chamber 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 itself under deformation recovery until it is completely closed. At this time, pure water will hardly flow through the flow regulating port 1722.

[0074] Therefore, when the water consumption of the water terminal varies greatly, the elastic deformation of the flexible check portion 1721 can be used to change the amount of pure water flowing into the water outlet chamber 1148, thereby effectively solving the problem that the existing diverter 1 is limited by the deformation of the flow hole, which limits the maximum and minimum flow ranges that can be adjusted. In addition, once the opening of the flow regulating port 1722 is adjusted, the flow rate of pure water is relatively stable. During long-term use, compared with only setting a retractable flow hole, the risk of blockage can be reduced, thereby better ensuring the stability of the diverter assembly 17 and the diverter 1, and reducing the cost of processing and manufacturing and the cost of subsequent maintenance.

[0075] It should be noted that the elastically retractable flow hole is matched with the flexible check portion 1721 , that is, the flow hole and the flexible check portion 1721 are provided on the diverter assembly 17 at the same time.

[0076] Next, the specific structure of the above-mentioned flow dividing component 17 is described in detail in conjunction with the drawings.

[0077] Please refer to Fig.10As shown, the diverter assembly 17 includes a diverter balancing membrane 172 and a balancing spring 171. The diverter balancing membrane 172 is detachably connected between the valve body upper shell 116 and the valve body lower shell 117. In addition, the valve body upper shell 116 and the diverter balancing membrane 172 cooperate to form an upper water outlet cavity 11482. The valve body lower shell 117 and the diverter balancing membrane 172 cooperate to form a lower water outlet cavity 11481. The balancing spring 171 is arranged between the diverter balancing membrane 172 and the inner cavity wall of the upper water outlet cavity 11482.

[0078] Among them, see Figures 1 to 7 , the shunt balance membrane 172 is made of elastic material (such as silicone, rubber and other materials), and a diaphragm through hole 1724 is provided on the shunt balance membrane 172. The above-mentioned flow hole is a diaphragm through hole 1724. At this time, the flow hole can also be elastically retracted. Further, the above-mentioned 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 may cause the flow hole to deform, which plays a role in finely adjusting the flow and improving the adjustment accuracy of the shunt component 17 and the diverter 1. When the flow demand of pure water is large, the flexible check portion 1721 can be deformed under the action of a large pressure difference, allowing a large amount of pure water to pass through. This combination is equivalent to a multi-stage adjustment system, which can accurately adjust the flow through the diverter 1 according to different working conditions (such as different water use speeds of water tankless pipeline machines), and very effectively reduces the probability of frequent start and stop of the water purifier. At the same time, through the synergistic effect of the flow holes on the splitter balance membrane 172 and the flexible check portion 1721, the pressure balance on both sides of the splitter assembly 17 can be better maintained. That is, they can flexibly adjust their own states 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 splitter 1 and reduce the damage to its components and system failures caused by pressure imbalance.

[0079] In this way, when the water consumption of the tankless pipeline machine is large, the pressure on the side of the diverter balance membrane 172 close to the first water supply port 1144 is greatly different from the pressure on the side of the diverter assembly 17 facing away from the first water supply port 1144, and the diverter balance membrane 172 will produce elastic deformation toward the side of the first water supply port 1144 and compress the balance spring 171. When the water consumption of the tankless pipeline machine decreases, the pressure difference on both sides of the diverter balance membrane 172 decreases, and almost no pure water flows through the first water supply port 1144, which means that there is no corresponding pressure condition generated by the flow of pure water. At this time, the state of both sides of the diverter balance membrane 172 is restored to the initial equilibrium state. Then, under the action of the elastic deformation of the diverter balance membrane 172 itself and the elastic deformation of the balance spring 171, the diverter balance membrane 172 recovers its deformation on the side facing away from the first water supply port 1144 until the diverter balance membrane 172 abuts against the reflux guide portion 1171 to seal the guide flow channel 1172. Such settings will have the following unexpected effects:

[0080] 1. When the water consumption of the tankless pipeline machine is large, the pressure on the side of the diverter balance membrane 172 close to the first water supply port 1144 is greatly different from the pressure on the side of the diverter assembly 17 facing away from the first water supply port 1144. The diverter balance membrane 172 will produce elastic deformation toward the side of the first water supply port 1144 and compress the balance spring 171. At this time, the balance spring 171 plays a buffering role and absorbs part of the pressure to prevent the diverter balance membrane 172 from being damaged due to excessive instantaneous pressure. When the water consumption of the tankless pipeline machine decreases, the pressure difference on both sides of the diverter balance membrane 172 decreases. Since the balance spring 171 stores elastic potential energy after being compressed, the balance spring 171 will release the elastic potential energy to help the diverter balance membrane 172 recover from deformation on the side facing away from the first water supply port 1144.

[0081] 2. The elastic properties of the shunt balance membrane 172 can automatically adjust the size of the flow hole according to the change of the pressure difference. The balance spring 171 cooperates with it to more finely control the deformation degree of the shunt balance membrane 172, thereby improving the shunt accuracy of the shunt 1. For example, when the pressure difference changes slightly, the slight deformation of the shunt balance membrane 172 and the slight expansion and contraction of the balance spring 171 work together to more accurately adjust the amount of pure water flowing through, thereby better realizing the function of automatically maintaining the pressure difference on both sides of the shunt balance membrane 172.

[0082] 3. During the use of the entire water purification system, the water consumption of the water tankless pipeline machine changes dynamically. The balance spring 171 and the diverter balance membrane 172 cooperate with each other to effectively adjust the pressure balance inside the water purification system under different water use conditions. This cooperation enables the diverter 1 to adapt to complex and changeable working conditions, reduces system failures caused by factors such as sudden pressure changes, enhances the stability and reliability of the system, and extends the service life of the diverter 1. In addition, when the water consumption of the water tankless pipeline machine changes rapidly, the synergistic effect of the balance spring 171 and the diverter balance membrane 172 can enable the diverter 1 to respond quickly. For example, when the water consumption of the water tankless pipeline machine suddenly increases, the balance spring 171 can quickly buffer the deformation of the diverter balance membrane 172, causing the flexible check portion 1721 to quickly increase and increase the water flow rate. When the water consumption of the water tankless pipeline machine suddenly decreases, the two can reset the diverter balance membrane 172 in time to reduce the flow of pure water, thereby optimizing the dynamic response capability of the diversion process.

[0083] It should be added that the specific Figure 7 As shown, the flexible check portion 1721 is a duckbill structure, and a duckbill cavity 1723 is arranged inside the flexible check portion 1721. The duckbill cavity 1723 penetrates the flow-dividing balance membrane 172 and forms a duckbill cavity opening on the side of the flow-dividing balance membrane 172 facing away from the flexible check portion 1721. For details, see Figures 3 to 7 The flexible check portion 1721 includes a duckbill deformation portion 17211 and a base 17212 fixedly connected to the diverter balancing membrane 172. The duckbill deformation portion 17211, the base 17212 and the diverter balancing membrane 172 are integrally formed to facilitate processing and manufacturing, and can also ensure the integrity of the diverter balancing membrane 172, so that the diverter balancing membrane 172 has good comprehensive performance (such as elasticity, etc.). The duckbill deformation portion 17211 is protruded from the base 17212 toward the water outlet upper cavity 11482, and in the protruding direction, the cross-sectional area of ​​the duckbill deformation portion 17211 away from the diverter balancing membrane 172 is smaller than the cross-sectional area close to the diverter balancing membrane 172. Preferably, the cross-sectional area of ​​the duckbill deformation portion 17211 gradually decreases along the protruding direction, and the cross-section here is parallel to the large surface of the shunt balancing membrane 172. The large surface of the shunt balancing membrane 172 is the side with the largest area in the shunt balancing membrane 172. The flow regulating port 1722 is arranged on the end of the duckbill deformation portion 17211 away from the shunt balancing membrane 172, and the duckbill cavity 1723 is connected to the flow regulating port 1722.

[0084] As a preferred method of this embodiment, please refer to Figure 2 , Figure 3 , Figure 4 and Figure 7As shown, the above-mentioned shunt assembly 17 also includes a diaphragm top cover 173, and a top cover through hole 1731 is provided on the diaphragm top cover 173. The top cover through hole 1731 is connected to the diaphragm through hole 1724. At this time, the top cover through hole 1731 and the diaphragm through hole 1724 constitute the above-mentioned flow hole. The diaphragm top cover 173 is arranged on the side of the shunt balance membrane 172 close to the first water supply port 1144, and the above-mentioned flexible check portion 1721 protrudes toward one side of the diaphragm top cover 173 and penetrates the diaphragm top cover 173, that is, as shown in FIG. Figure 3 and Figure 4 As shown, a top cover through hole 1732 is provided on the diaphragm top cover 173, and the duckbill deformation portion 17211 of the flexible check portion 1721 passes through the top cover through hole 1732 toward the water outlet upper chamber 11482 and protrudes from the top cover through hole 1732, and one end of the balance spring 171 abuts against the inner cavity wall of the water outlet upper chamber 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 supporting point of the balance spring 171, and the diaphragm top cover 173 has good structural strength. During the diversion process, the balance spring 171 can adjust the balance of the system through the force between the diaphragm top cover 173 and the inner cavity wall. For example, when the flow rate of pure water changes or the internal pressure of the water outlet upper chamber 11482 fluctuates, the balance spring 171 can be retracted and retracted according to the position change of the diaphragm top cover 173, thereby adjusting the pressure balance and flow balance of the diverter 1 to ensure the stability of the diversion.

[0085] Further, please refer to Figure 2 As shown, the flow diverter assembly 17 has a stop limiter 1733 protruding toward the first water supply port 1144, and the flow diverter assembly 17 generates a relative displacement toward the first water supply port 1144 until the stop limiter 1733 abuts against the inner wall of the water outlet cavity 1148, specifically, the stop limiter 1733 abuts against the inner wall of the water outlet upper cavity 11482. At this time, the flow diverter assembly 17 is the maximum displacement generated by the flow diverter assembly 17. In this way, when the flow diverter assembly 17 is under a large pressure difference, the stop limiter 1733 can abut against the inner wall of the water outlet upper cavity 11482, forming a reliable mechanical limit, effectively limiting the further movement of the flow diverter assembly 17, thereby preventing the flow diverter balancing membrane 172 from being excessively deformed due to excessive force, eliminating the hidden danger of damage to the flow diverter balancing membrane 172 due to excessive deformation, and improving the service life of the diverter 1.

[0086] Preferably, please combine Figure 3 , Figure 4 and Figure 7As shown, the stopper 1733 is arranged on the diaphragm top cover 173, and the stopper 1733 is preferably formed integrally with the diaphragm top cover 173, and the stopper 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 stopper 1733 will not be easily deformed or damaged during frequent displacement and collision, so as to better maintain the stability and accuracy of the entire diverter 1. In other embodiments, the stopper 1733 can also be arranged on the diverter balance membrane 172.

[0087] The unexpected effect is that Figures 3 to 7 As shown, the stop limiter 1733 is located on the outside of the balance spring 171, and the stop limiter 1733 is extended along the circumference of the balance spring 171 to constrain the end of the balance spring 171 to the inside of the stop limiter 1733 to ensure the stability of the balance spring 171 during the deformation process. It should be noted that the inner diameter of the stop limiter 1733 can be selected to match the outer diameter of the balance spring 171. Of course, the inner diameter of the stop limiter 1733 can also be larger than the outer diameter of the balance spring 171. In addition, a spring limiter column 1734 can be protruded on the side of the diaphragm top cover 173 facing the first water supply port 1144, and the end of the balance spring 171 is sleeved on the spring limiter column 1734, so that the stop limiter 1733 can be used to achieve the purpose of double limitation of the balance spring 171. In addition, the spring limiter column 1734 can also quickly position the balance spring 171 during the assembly process to improve the assembly efficiency.

[0088] Further, please refer to Figure 3 As shown, the stop limit portion 1733 is provided with an escape opening 1735 corresponding to the flexible non-return portion 1721. Figure 6 As shown, the avoidance opening 1735 preferably passes through the stop limit portion 1733 along the protruding direction of the stop limit portion 1733, so that the stop limit portion 1733 is formed into two arc-shaped and oppositely arranged stop portions, and the number of the flexible non-return portions 1721 is configured to be two, and each flexible non-return portion 1721 is located between the two stop portions. Such a configuration will have the following unexpected technical effects:

[0089] 1. The avoidance opening 1735 provides space for the flexible check portion 1721, which not only enables the flexible check portion 1721 to normally protrude toward one side of the diaphragm top cover 173 and penetrate therethrough, but also ensures that each flexible check portion 1721 is deformed according to the water flow pressure within a limited space, thereby flexibly adjusting the diversion of the water flow.

[0090] 2. Under the action of the avoidance opening 1735, the flexible check portion 1721 on the diaphragm top cover 173 and the shunt balancing membrane 172 can avoid mutual extrusion and friction during operation, effectively reducing the interference and wear between the flexible check portion 1721 and the stop limit portion 1733, thereby increasing the service life of the shunt assembly 17. The reliability and durability of the shunt balancing membrane 172 and the shunt assembly 17 are improved.

[0091] 3. If the number of flexible check parts 1721 is configured as two, they can work together when facing different water flow pressures and flow conditions. For example, when the water flow impacts the diversion balance membrane 172, if there is only one flexible check part 1721, it may be deformed to one side due to the uneven impact of the water flow, resulting in unstable diversion. The two relatively distributed flexible check parts 1721 will be able to balance this impact force with each other. When the flexible check part 1721 on one side is subject to a large water flow pressure and tends to open, the flexible check part 1721 on the other side can make corresponding adjustments according to the pressure difference, thereby maintaining the stability of the diversion, making the water flow out of the first water supply port 1144 more uniform and stable.

[0092] 4. Under the action of the avoidance port 1735, when the stop limit portion 1733 abuts against the inner wall of the water outlet upper cavity 11482, the purified water can still flow to the first water supply port 1144 through the avoidance port 1735, thereby ensuring the smoothness, stability and continuity of the flow of purified water, and effectively preventing the purified water from being blocked by the stop limit portion 1733 and causing a sudden change in the water flow pressure, thereby ensuring the stability and reliability of the use of the diverter 1 and the drinking water purification system.

[0093] Considering that when the stop limit part 1733 abuts against the inner wall of the water outlet upper cavity 11482, the water output of the first water supply port 1144 is relatively large, that is, the demand for pure water of the water tankless pipeline machine is large. In order to further ensure the supply of pure water, a water passing notch 1736 is provided on the stop limit part 1733, that is, each stop part of the stop limit part 1733 is provided with a water passing notch 1736 near one end of the first water supply port 1144. This embodiment does not limit the shape and size of the water passing notch 1736, and 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 notch 1736, thereby ensuring that sufficient pure water flows to the first water supply port 1144 and is supplied to the water tankless pipeline machine.

[0094] Of course, it should also be noted that, in addition to the stop limiter 1733 on the diverter assembly 17 abutting against the inner wall of the water outlet upper cavity 11482, the specific Fig.10As shown, the inner cavity wall of the water outlet upper cavity 11482 is convexly formed with a stop boss 1161 toward the side of the diverter assembly 17. Specifically, the stop boss 1161 is a convexly formed inner cavity wall of the water outlet upper cavity 11482 toward the side of the diverter assembly 17. The stop boss 1161 is preferably integrally formed with the valve body upper shell 116 for easy production. The inside of the stop boss 1161 is provided with a first water supply channel 1162 connected to the first water supply port 1144, and the stop limit portion 1733 can abut against the stop boss 1161.

[0095] On the one hand, the stop boss 1161 cooperates with the stop limiter 1733 on the diaphragm top cover 173 to more accurately limit the deformation degree of the diverter balance membrane 172. When the diverter balance membrane 172 is deformed toward the first water supply port 1144 under the influence of factors such as water flow and water pressure, the stop limiter 1733 abuts against the stop boss 1161, thereby further preventing the diverter balance membrane 172 from excessive deformation, and better ensuring that the diverter balance membrane 172 works within a safe range. On the other hand, pure water will be orderly diverted 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 turbulence, thereby improving the working efficiency and accuracy of the diverter 1.

[0096] Preferably, please refer to Fig.10 As shown, the inner wall of the flow channel of the first water supply channel 1162 is convexly formed with a spring force-bearing body 1163, and the spring force-bearing body 1163 can be optionally extended along the circumference of the first water supply channel 1162, or the number of the spring force-bearing bodies 1163 is configured to be multiple, each spring force-bearing body 1163 can be optionally hemispherical or prism-shaped, and multiple spring force-bearing bodies 1163 are arranged along the circumference of the first water supply channel 1162. Figure 2 As shown, the end of the balance spring 171 is inserted into the first water supply channel 1162, and the end of the balance spring 171 abuts against the spring force 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 the operation, that is, the end of the balance spring 171 abuts against the spring force body 1163, and the peripheral 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 that may be generated by the balance spring 171 during the operation, thereby better ensuring that the balance spring 171 can normally play its balancing and regulating functions, and transmit force more accurately, ensuring and improving the diversion accuracy of the diverter 1.

[0097] Of course, in order to facilitate the assembly of the end of the balance spring 171 into the first water supply channel 1162, see Fig.10The port of the first water supply channel 1162 used to connect to the upper water outlet cavity 11482 is the second guide port, and a positioning guide portion 1164 is provided on the second guide port. The positioning guide portion 1164 is obliquely connected to the inner wall of the flow channel of the first water supply channel 1162 along the central axis direction of the first water supply channel 1162. During the assembly of the balance spring 171, it is only necessary to abut the end of the balance spring 171 against 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, thereby achieving the purpose of self-positioning and improving the assembly efficiency and convenience of the flow balance spring 171.

[0098] As another preferred method of this embodiment, please refer to Figure 3 , Figure 4 as well as Figure 5 As shown, the shunt assembly 17 further includes a diaphragm base 174, on which a base through hole 1741 is provided, and the base through hole 1741 is connected to the diaphragm through hole 1724. It can be understood that when the shunt assembly 17 is not equipped with the diaphragm top cover 173, the base through hole 1741 and the diaphragm through hole 1724 constitute the above-mentioned flow hole. Alternatively, when the shunt assembly 17 is equipped with the above-mentioned diaphragm top cover 173, the shunt balance membrane 172 is sandwiched between the diaphragm top cover 173 and the diaphragm base 174, and the top cover through hole 1731, the diaphragm through hole 1724, and the base through hole 1741 constitute the above-mentioned flow hole. The diaphragm base 174 is arranged on the side of the shunt balance membrane 172 facing away from the first water supply port 1144. In this way, when the pure water flow rate flowing out of the first water supply port 1144 suddenly decreases, if the water inlet flow rate of the water purifier fails to make corresponding adjustments in time, the pressure of the water outlet upper chamber 11482 will rise rapidly. In this case, the diaphragm base 174 can provide strong support for the shunt balance membrane 172. The diaphragm base 174 has a certain structural strength. Due to the support of the diaphragm base 174, the shunt balance membrane 172 will not be excessively deformed toward the side of the reflux guide 1171 due to reverse pressure. Thereby ensuring the stability and reliability of the entire shunt assembly 17, avoiding blockage or other failures caused by excessive deformation of the shunt balance membrane 172, ensuring that the water purifier can operate continuously and stably 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.

[0099] It can be understood that the "pressure difference formed by the pure water inlet 1143, the first water supply port 1144, and the second water supply port 1145" recorded above is also 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 diversion balancing membrane 172.

[0100] For further details, please refer to Figures 1 to 4As shown, a base avoidance hole 1742 is also provided on the diaphragm base 174, and the size of the base avoidance hole 1742 is larger than the diameter of the reflux guide portion 1171, and the reflux guide portion 1171 can pass through the base avoidance hole 1742 to abut against the shunt balance membrane 172. In this embodiment, the shape of the base avoidance hole 1742 is not specifically limited, for example, it can be selected as a circular hole, or a square hole, or an elliptical hole, etc. In this way, the shunt balance membrane 172 will be able to accurately seal the guide flow channel 1172, thereby effectively blocking the reflux path of pure water. This also ensures that under normal shunt working conditions, the water flow can flow in an orderly manner according to the predetermined shunt channel, avoiding the unwarranted loss or reflux of pure water interfering with the normal water outlet process. At the same time, the flexibility of the shunt balance membrane 172 is utilized to improve the sealing between the shunt balance membrane 172 and the reflux guide portion 1171.

[0101] It should be noted that if Figure 7 As shown, the diaphragm base 174 is provided with a base water flow port 1743 connected to the flow regulating port 1722. That is, the base water flow port 1743 on the diaphragm base 174 is correspondingly arranged and connected to the duckbill cavity 1723 of the flexible check portion 1721, ensuring that the purified water can pass through the base water flow port 1743 and flow into the duckbill cavity 1723, and when the flow regulating port 1722 is opened, the purified water will be able to pass through the flow regulating port 1722 and flow into the water outlet upper cavity 11482.

[0102] As another preferred method of this embodiment, please refer to Figure 7 As shown, the diaphragm top cover 173 extends a flow guide extension body 175 toward the diaphragm through hole 1724. The flow guide extension body 175 is preferably formed integrally with the diaphragm top cover 173. The flow guide extension body 175 is provided with a water through hole 1751 through the inside. The through hole here should be understood as the water through hole 1751 passing through 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 through hole 1751 constitute the flow hole. In the process of pure water flowing through the water through hole 1751, it is equivalent to pure water flowing from the water outlet lower chamber 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 chamber 11482.

[0103] Such a configuration not only plays a good guiding role in the flow of pure water through the water through hole 1751, but also makes the flow of pure water in the through hole more orderly and smooth, reducing the turbulence and energy loss of the water flow. At the same time, the tight and orderly connection structure between the various components, during the assembly process, uses the guide extension body 175 to accurately plug the diaphragm through hole 1724 of the shunt balance membrane 172 and the base through hole 1741 of the diaphragm base 174, thereby improving the positioning accuracy and assembly efficiency.

[0104] Furthermore, please combine Figures 4 to 7 As shown, the flow guide extension body 175 passes through the top cover through hole 1731, the diaphragm through hole 1724, and the base through hole 1741 in sequence and extends out of the base through hole 1741. The part of the flow guide extension body 175 extending out of the base through hole 1741 is provided with a snap protrusion 1752, and the snap protrusion 1752 is snapped on the diaphragm base 174, so as to realize the snap connection between the diaphragm top cover 173 and the diaphragm base 174, so as to ensure that the shunt balance membrane 172 is clamped between the diaphragm top cover 173 and the diaphragm base 174, which is conducive to the convenience and efficiency of disassembly and assembly, thereby facilitating the replacement of subsequent components. And the structure is simple, reducing the processing cost of each component. Of course, the side of the diaphragm base 174 facing away from the shunt balance membrane 172 can be provided with a base slot, and the snap protrusion 1752 is snapped in the base slot.

[0105] Preferably, the flow guide extension 175 is located inside the top cover through hole 1731, and a buffer gap is formed between the flow guide extension 175 and the hole wall of the top cover through hole 1731. This not only ensures that the assembler can observe the diaphragm through hole 1724 of the shunt balance membrane 172 through the buffer gap during the assembly process, which is convenient for assembly positioning and further improves assembly efficiency. At the same time, the buffer gap serves as a space for the flow guide extension 175 to deform during the clamping process, thereby facilitating the clamping protrusion 1752 to be clamped on the diaphragm base 174 or to detach the clamping protrusion 1752 from the diaphragm base 174.

[0106] It should be noted here that, in other embodiments, the flow guide extension body 175 can also be extended from the diaphragm base 174 toward the diaphragm through hole 1724, then the flow guide extension body 175 passes through the base through hole 1741, the diaphragm through hole 1724, the top cover through hole 1731 in sequence and extends out of the top cover through hole 1731, and the part of the flow guide extension body 175 extending out of the top cover through hole 1731 is provided with a snap protrusion 1752, and the snap protrusion 1752 is snapped onto the diaphragm top cover 173, which belongs to the conventional replacement method of the above-mentioned preferred embodiment.

[0107] It should also be noted that if Figure 7As shown, the diameter of the water through hole 1751 on the side close to the diaphragm base 174 is smaller than the diameter on the side close to the diaphragm top cover 173. Preferably, the diameter of the water through hole 1751 gradually increases along the direction of water flow. According to the above description, the direction of water flow is the direction from the base through hole 1741 to the diaphragm through hole 1724 and the top cover through hole 1731 in sequence. Therefore, that is, the diameter of the water through hole 1751 gradually increases along the first direction, and the first direction is from the side of the diaphragm base 174 along the central axis of the water through hole 1751 and toward the side of the diaphragm top cover 173. In this way, when pure water flows in from the side with a smaller diameter and then flows out from the other side with a larger diameter, the cross-sectional area of ​​the water through hole 1751 gradually increases. According to the flow formula Q=vA (Q is the flow rate, v is the flow rate, and A is the cross-sectional area), when the flow rate remains basically unchanged, the cross-sectional area increases and the flow rate decreases. A lower flow rate can reduce the pressure loss of water in the water through hole 1751. At the same time, when pure water flows into the water through hole 1751 from a smaller diameter to one side, a relatively orderly flow state can be formed. As the diameter size gradually increases, the pure water has enough space to transition smoothly, reducing the turbulence caused by sudden spatial changes, thereby effectively avoiding the generation of small bubbles in the pure water. In addition, the smaller diameter side can also limit the impact force of the water flow. Reduce physical damage to the water through hole 1751 and the diversion balance membrane 172, such as scratches.

[0108] In the above, the pressure on the side of the shunt balance membrane 172 close to the first water supply port 1144 is significantly different from the pressure on the side of the shunt assembly 17 facing away from the first water supply port 1144. The shunt balance membrane 172 will produce elastic deformation toward the first water supply port 1144, and drive the membrane top cover 173 and / or the membrane base 174 to move toward the first water supply port 1144. In order to ensure and increase the amount of elastic deformation that the shunt balance membrane 172 will produce toward the first water supply port 1144, such as Figures 4 to 7 As shown, a deformation groove 1725 is provided on the flow-dividing balancing membrane 172, and the deformation groove 1725 is a U-shaped groove. The deformation groove 1725 is located outside the flexible check portion 1721, and the deformation groove 1725 is extended along the circumference of the membrane top cover 173. It can be understood that the direction of the notch of the deformation groove 1725 can be set and adjusted according to the structural design and design requirements. In this embodiment, the notch of the deformation groove 1725 is preferably set toward the water outlet lower cavity 11481.

[0109] In this way, when the shunt balancing membrane 172 is subjected to pressure, the circumferentially extending deformation groove 1725 can provide sufficient space for the deformation of the shunt balancing membrane 172, which not only makes the stress concentrated in the deformation groove 1725, but also makes the stress effectively released and produces uniform deformation, thereby well avoiding the risk of excessive concentration of stress in other parts of the shunt balancing membrane 172 and causing rupture and fatigue damage. At the same time, it can also effectively enhance the deformation ability of the shunt balancing membrane 172 in a limited space. When the shunt balancing membrane 172 is affected by the pressure change in the water outlet cavity 1148, the deformation groove 1725 can be used as a pre-set deformation area to better guide the shunt balancing membrane 172 to produce a larger deformation, so that the shunt balancing membrane 172 can make a sensitive response according to these pressure differences, so as to achieve the purpose of better balancing the pressure in all directions, which is conducive to the shunt component 17 to more accurately control the shunt.

[0110] Further, please refer to Figures 4 to 7 As shown, the groove wall of the deformation groove 1725 away from the flexible check portion 1721 is protruded toward the outside and is formed with a diaphragm clamping portion 1726. Preferably, the diaphragm clamping portion 1726 is arranged on the groove wall of the deformation groove 1725 close to the groove mouth side, and the diaphragm clamping portion 1726 is integrally formed with the shunt balancing membrane 172. The diaphragm clamping portion 1726 is extended along the groove length direction of the deformation groove 1725. The diaphragm clamping portion 1726 is clamped between the valve body upper shell 116 and the valve body lower shell 117, thereby achieving the purpose of detachably connecting the shunt balancing membrane 172 between the valve body upper shell 116 and the valve body lower shell 117, thereby improving the assembly efficiency of the diverter 1.

[0111] Specifically, Fig.10 As shown, a diaphragm clamping groove 1173 is provided on the valve body lower shell 117, and the diaphragm clamping portion 1726 is embedded in the diaphragm clamping groove 1173, so that the diaphragm clamping portion 1726 is more firmly connected between the valve body upper shell 116 and the valve body lower shell 117, and the flow-dividing balancing membrane 172 can be more firmly assembled on the valve housing 11. In addition, the groove wall of the diaphragm clamping groove 1173 close to the flexible check portion 1721 is extended toward the inside of the deformation groove 1725, that is, the groove wall of the diaphragm clamping groove 1173 close to the flexible check portion 1721 is received in the deformation groove 1725, so that the flow-dividing assembly 17 and the valve housing 11 are more compact, which is conducive to reducing the volume of the diverter 1. It should be noted that in addition to the diaphragm clamping groove 1173 being provided on the valve body lower shell 117, the diaphragm clamping groove 1173 is provided on the valve body upper shell 116.

[0112] Preferably, if Fig.10As shown, the valve body upper shell 116 is provided with a diaphragm anti-slip groove 1165, and the diaphragm clamping portion 1726 is provided with a diaphragm anti-slip body 1727 plugged into the diaphragm anti-slip groove 1165, which further improves the stability of the connection between the split flow balancing membrane 172 and the valve housing 11. It can be understood that the diaphragm clamping groove 1173 is provided on the valve body upper shell 116, and the diaphragm anti-slip groove 1165 is correspondingly provided on the valve body lower shell 117.

[0113] In the drinking water purification system, when the user starts or shuts down the tankless pipeline machine, the flow velocity of the pure water flowing through the diverter 1 changes dramatically, thus generating a water hammer phenomenon. The instantaneous pressure wave generated by the water hammer may damage the diverter assembly 17 in the diverter 1. Based on this, the inventor also provides a preferred method, see Figure 1 and Figure 2 The diverter 1 further includes a water hammer absorber 18, which is located between the diverter assembly 17 and the pure water inlet 1143, and is detachably connected to the valve housing 11. Specifically, the water hammer absorber 18 is installed inside the water outlet lower chamber 11481, so that the pressure wave generated by the water hammer has been buffered before entering the water outlet upper chamber 11482.

[0114] Such a configuration can buffer the pressure wave before it reaches the diverter assembly 17, reduce the risk of damage to the diverter assembly 17 caused by the high pressure generated by the water hammer, and increase the service life of the diverter 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 housing 11. In addition, under the action of the water hammer absorber 18, the stability of the diverter assembly 17 during the adjustment process can be guaranteed, the interference of the water hammer on the diverting process can be reduced, the normal operation of the diverter 1 can be ensured, and the diverting accuracy of the diverter 1 can be improved.

[0115] Preferably, please refer to Fig.10 As shown, a plurality of water flow buffer holes 181 are provided on the water hammer absorber 18, and the plurality of water flow buffer holes 181 are evenly distributed, and the water outlet cavity 1148 is connected to the pure water inlet 1143 through the plurality of water flow buffer holes 181. When pure water flows into and passes through the water hammer absorber 18 with the water flow buffer holes 181 from the pure water inlet 1143, the water flow buffer holes 181 play a role in buffering the water flow. Because when the pure water flows through the water flow buffer holes 181, its flow direction and speed will change. For example, when the fast-flowing pure water passes through the plurality of water flow buffer holes 181, it will be dispersed into multiple small water flows and consume part of the kinetic energy of the water flow, thereby reducing the degree of sudden change in the water flow speed and alleviating the possibility of water hammer.

[0116] In addition, the presence of the water flow buffer hole 181 can also adjust the pressure change of the water flow. According to the Bernoulli principle, when the water flows through the water flow buffer hole 181, its pressure will form a certain pressure difference on both sides of the water hammer absorber 18, which plays a certain degree of regulation. 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. This flow can alleviate the sharp rise in pressure, make the pressure change more gentle, and further reduce the water hammer phenomenon.

[0117] It should be noted that the present application does not limit the number, size and distribution of the water flow buffer holes 181, which can be set and adjusted according to the structural design and design requirements. By reasonably setting the number, size and distribution of the water flow buffer holes 181, the pulse frequency of the pure water flow can also be changed. For example, when water hammer occurs, high-frequency pressure pulses will appear. The water flow buffer 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. Therefore, high-frequency pressure pulses can be converted into relatively low-frequency pulses (that is, irregular pulses become more regular), and the low-frequency, regular pressure changes have relatively small impacts on the diverter 1, which is also conducive to reducing the harm of water hammer.

[0118] For further details, please refer to Fig.10 and Fig.11 As shown, the water hammer absorber 18 is provided with a positioning assembly hole 182 for inserting the backflow guide 1171, and the aperture of the positioning assembly hole 182 is adapted to the diameter of the backflow guide 1171, so that the backflow guide 1171 can be quickly and firmly installed on the valve body lower shell 117 of the valve housing 11. In order to ensure that the water hammer absorber 18 can be more firmly installed on the valve body lower shell 117, and to make the force between the water hammer absorber 18 and the valve body lower shell 117 more balanced, the inner wall of the water outlet lower cavity 11481 is convexly formed with an absorber boss 1174, and the edge of the water hammer absorber 18 abuts against the absorber boss 1174, which has a simple structure and is easy to disassemble and assemble, which is conducive to subsequent maintenance and repair.

[0119] Of course, please refer to Fig.11 As shown, the absorbing member boss 1174 is formed with a limiting convex portion 1175 protruding toward one side of the diverter assembly 17, and the edge of the water hammer absorbing member 18 is provided with a limiting notch 183 for inserting the limiting convex portion 1175. In this way, the limiting notch 183 cooperates with the limiting convex portion 1175 to prevent the water hammer absorbing member 18 from deflecting around the reflux guide portion 1171, thereby guiding the pure water flow more stably.

[0120] In some other embodiments, the water hammer absorber 18 may be a piston-type water hammer arrester or a diaphragm-type water hammer arrester, both of which are relatively mature existing technologies in water hammer arresters, and their structures are not described in detail here. Alternatively, the water hammer absorber 18 may be a slow-closing check valve.

[0121] As the preferred method of this embodiment, please refer to Figure 8 , Fig. 9 and Fig.10 As shown, the diverter 1 also includes a water filter 19, the valve body lower shell 117 of the valve shell 11 is provided with a water inlet channel 1176, the water outlet lower chamber 11481 of the water outlet chamber 1148 is connected to the pure water inlet 1143 through the water inlet channel 1176, the water filter 19 is arranged in the water inlet channel 1176, the water filter 19 is provided with a filter hole 191 in the extension direction of the water inlet channel 1176, and a water 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 drainage opening 192 connected to the water gap, and the opening size of the drainage opening 192 is larger than the aperture of the filter hole 191.

[0122] In this arrangement, since the filter holes 191 provided on the water filter element 19 can perform re-filtration in the flow direction of the pure water, small particles that may appear when the water purifier filter element is nearing the end of its service life are prevented from flowing into the water outlet cavity 1148 and the tankless pipeline machine, 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 drinking water.

[0123] More importantly, when pure water passes through the filter hole 191 of the water filter 19, due to the relatively small aperture of the filter hole 191, the water flow will generate a certain resistance when passing through the filter hole 191. The presence of the drainage port 192 can play a role in diversion. The opening size of the drainage port 192 is larger than the aperture of the filter hole 191. A part of the water can flow through the drainage port 192 and the water gap, sharing part of the water flow, so that the water flow speed through the filter hole 191 will not be too high, thereby reducing the water resistance of this part. At the same time, the presence of the drainage port 192 and the water gap also helps to balance the pressure in the water inlet channel 1176. The water can redistribute the flow between the filter hole 191 and the drainage port 192, making the pressure distribution in the entire water inlet channel 1176 more uniform, and also reducing the water resistance of the water inlet channel 1176 and the entire diverter 1.

[0124] Preferably, see Figure 8 , Fig. 9 and Fig.10The water filter 19 includes a body fastening portion 193 and a body water filter portion 194 fixedly connected to the body fastening portion 193. The fixed connection here is preferably formed in one piece to facilitate production. The drainage port 192 and the filter hole 191 are both arranged on the body water filter portion 194. Specifically, the body water filter portion 194 has a water filter portion bottom wall and a water filter portion side wall extending along the circumference of the water filter portion bottom wall, and the water filter portion bottom wall and the water filter portion side wall cooperate to form a filter cavity, and the filter cavity has a filter cavity port arranged opposite to the water filter portion bottom wall. Among them, the filter hole 191 is arranged on the water filter portion bottom wall, the drainage port 192 is arranged on the water filter portion side wall, the body fastening portion 193 is arranged on the side of the water filter portion side wall close to the filter cavity port, and the body fastening portion 193 is arranged to extend along the circumference of the filter cavity port. The main body fastening portion 193 is formed by staggered protrusions toward the outer side of the water filter portion side wall. When the water filter 19 is inserted into the water inlet channel 1176, the main body fastening portion 193 can be detachably connected to the valve body lower shell 117 of the valve shell 11, and the main body water filter portion 194 and the inner side wall of the water inlet channel 1176 automatically form a water gap.

[0125] It should be noted that the drainage opening 192 is a drainage group, which includes a plurality of drainage holes arranged along the circumference of the main body water filter 194, and the aperture of each drainage hole is larger than the aperture of the filter hole 191. The drainage group can be configured as one group or multiple groups. Multiple drainage groups are evenly arranged along the extension direction of the water inlet channel 1176. Or, as Fig. 9 As shown, the drainage opening 192 may also be in the form of a strip hole, and the drainage opening 192 is extended along the circumferential portion of the main body water filter 194. The number of the drainage opening 192 may be one or more, and the plurality of drainage openings 192 are arranged and distributed along the extension direction of the water inlet channel 1176, and two adjacent drainage openings 192 are preferably staggered.

[0126] Preferably, if Figure 8As shown, a water filter buckle body 1177 is provided on the inner side wall of the water inlet channel 1176, and the water filter buckle body 1177 is provided along the circumferential direction of the water inlet channel 1176. The main body fastening part 193 is engaged with the water filter buckle body 1177, and the water filter buckle body 1177 extends along the extension direction of the water inlet channel 1176. Further, a fastening slot is provided on the water filter buckle body 1177, and a fastening protrusion 195 is provided on the main body fastening part 193, and the fastening slot is plug-connected with the fastening protrusion 195. In this way, it is effectively ensured that the water filter element 19 is stably installed and connected inside the water inlet channel 1176, and under the long-term impact of the water flow, the water filter element 19 will not be easily displaced, thereby ensuring that the filter hole 191 and the drainage port 192 can function normally and maintain the stability of the filtering function. At the same time, the water filter buckle body 1177 is snapped into the water filter slot, and the fastening slot is plugged into the fastening protrusion 195, making the installation of the water filter 19 more convenient. When assembling the diverter 1, the worker only needs to align the water filter 19 with the water inlet channel 1176 and perform the snap-in operation to complete the installation, which is also convenient for later disassembly, cleaning, replacement and maintenance. It should be noted that in addition to the above-mentioned fastening slot being set on the water filter buckle body 1177 and the fastening protrusion 195 being set on the main body fastening portion 193, the fastening slot can also be set on the main body fastening portion 193, and the fastening protrusion 195 is correspondingly set on the water filter buckle body 1177.

[0127] As a preferred mode of this embodiment, the diverter 1 also includes a water resistance member, which is used to increase the resistance of the water flow. The valve body lower shell 117 of the valve housing 11 is provided with a second water supply channel 1178, and the second water supply port 1145 is connected to the water outlet chamber 1148 through the second water supply channel 1178. The water resistance member is arranged in the second water supply channel 1178, and the water resistance member is detachably connected to the valve housing 11. Such a setting can effectively avoid pressure fluctuations caused by water flow impact. When the faucet is suddenly opened or closed, the rapid change of the water flow speed will produce a water hammer phenomenon, resulting in an instantaneous increase in the pressure in the second water supply channel 1178, and the resistance of the water resistance member to the water flow can slow down the sudden change of the water flow speed, thereby buffering this pressure change. At the same time, the water resistance member can also play a certain role in preventing backflow. When the pressure in the second water supply channel 1178 suddenly decreases, water backflow may occur. Since the water resistance member can increase the resistance of the backflow, the possibility of backflow is reduced.

[0128] In this embodiment, please refer to Figure 8 and Fig.10As shown, a water-passing support frame 1131 having a support water outlet 1134 is provided on the valve body lower shell 117. Preferably, the water-passing support frame 1131 is preferably configured as two, and the two water-passing support frames 1131 are staggered, and the inner wall of the waterway 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 provided inside the second water supply channel 1178. The water-passing support frame 1131 is preferably formed integrally with the valve body lower shell 117, and the water resistance member abuts against and connects the water-passing support frame 1131. Further, a support positioning portion 1132 is provided on one side of the water-passing support frame 1131 facing the water outlet chamber 1148, and a water resistance plug for plugging the support positioning portion 1132 may be provided on the water resistance member, so that the water resistance member can be stably installed and fixed on the support positioning portion 1132.

[0129] Preferably, please Figure 8 , Fig.10 and Fig.11 As shown, the inner wall of the flow channel of the second water supply channel 1178 is provided with a bearing protrusion 1133, and the bearing protrusion 1133 is extended along the extension direction of the second water supply channel 1178. The water resistance member abuts against the bearing protrusion 1133, so that the water resistance member is more firmly installed 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 supply port 1145 is smaller than the cross-sectional area of ​​the side close to the second water supply port 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 toward the side close to the second water supply port 1145.

[0130] In this way, in the molding process of manufacturing the valve body lower shell 117, the draft angle of the bearing protrusion 1133 is used to facilitate the separation of the mold and the valve body lower shell 117, and the bearing protrusion 1133 may be torn, deformed, and other defects during the demoulding process, affecting the product quality. At the same time, since the cross-sectional area of ​​the bearing protrusion 1133 gradually increases, it is equivalent to having a guiding role when installing the water resistance member. The water resistance member can more easily slide into the correct installation position along the draft angle direction, which is helpful for the installation of the water resistance member and makes the water resistance member more stable after installation. Because after the water resistance member is installed, the part with a larger cross-sectional area of ​​the bearing protrusion 1133 can limit the movement of the water resistance member in the flow channel direction to a certain extent. For example, when the water flow impacts the water resistance member, the water resistance member will not easily move along the flow channel direction, ensuring that the water resistance member can stably and normally exert resistance to the water flow. In addition, the bearing protrusion 1133 can better guide the flow of pure water. As the cross-sectional area of ​​the bearing protrusion 1133 gradually increases, the water flow will change direction more smoothly when passing through the bearing protrusion 1133, reducing the turbulence of the water flow, thereby improving the stability and uniformity of the water flow.

[0131] As a preferred mode of this embodiment, the water resistance member includes a water resistance member body, and a plurality of flow-limiting water resistance holes are arranged on the water resistance member body, each of which is connected to the bracket water outlet 1134, and the water resistance member body is connected to the above-mentioned bearing protrusion 1133. In this way, when pure 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 water, but also make the water flow out in the form of foam, and multiple flow-limiting water resistance holes are connected to the bracket water outlet 1134, which can also make the water flowing out of the water outlet more evenly dispersed, so as to save water and prevent water splashing. In some embodiments, the water resistance member can be selected as a one-way valve assembly, a throttle valve, or a bubbler.

[0132] The unexpected effect is that Fig.10 As shown, when the water hammer absorber 18 is installed in the lower water outlet cavity 11481, the water hammer absorber 18 will better completely confine the water resistance member 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 absorber 18 is installed upstream of the water flow of the water resistance member, it can absorb and buffer the water hammer pressure wave before it reaches the water resistance member. This can protect the water resistance member and prevent the water resistance member from being damaged due to excessive water hammer pressure, ensuring that the water resistance member can normally perform its functions of limiting water flow and regulating pressure, and more accurately control the water flow according to the designed structure such as the flow-limiting water resistance hole, thereby providing a more stable water inlet condition for subsequent faucets or other water outlet equipment, reducing the impact of water hammer on the faucet, thereby extending the service life of the faucet and reducing the frequency of maintenance and replacement.

[0133] It should be noted that, in order to reduce the vibration of the water resistance member during the water resistance treatment process, a bearing slot for plugging and connecting the bearing protrusion 1133 may also be provided on the peripheral side wall of the water resistance member body. In addition, the aperture of the flow-limiting water resistance hole is between 0.5-1.5 mm to provide a relatively stable water flow resistance, thereby avoiding the risk of blockage during long-term use.

[0134] As a preferred mode of this embodiment, the diverter 1 also includes a water inlet filter, which is arranged at the raw water inlet 1141, wherein the water inlet filter is preferably a filter. In this way, it can effectively prevent some large particles of impurities (such as mud and sand, etc.) that may be contained in the tap water from flowing into the water inlet chamber 1147, thereby achieving the purpose of preliminary filtration, avoiding the risk of damage to the pressure regulating component 16 inside the diverter 1 and the risk of failure of the voltage stabilization of the diverter 1, and also reducing the total amount of impurities entering the water purifier, thereby extending the service life of the water purifier filter element to a certain extent. In conjunction with the water filter 19 arranged at the pure water inlet 1143, not only the purpose of double filtration of the diverter 1 is achieved, that is, although the pure water filtered by the water purifier has removed most of the impurities, bacteria and harmful substances, it may still be contaminated during the transportation process, such as particulate 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 pure water flowing to each water terminal is purer. At the same time, the drinking water purification system also achieves the triple filtration effect on the water source, thereby effectively ensuring that the drinking water purification system has good water quality and providing users with safer drinking water.

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