[0057] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0058] See also Figure 1 The embodiment of the present application proposes a drinking water purification system, including a water purifier 3, a tankless pipeline machine 2, a faucet 4 and a diverter 1. The water purifier 3 has a raw water inlet 31 and a pure water outlet 32; the tankless pipeline machine 2 has a water inlet 211; the faucet 4 has a pure water inlet 41, wherein the valve housing 11 includes a water inlet chamber 1147, a reflux chamber 1146 and a water outlet chamber 1148. The water inlet chamber 1147 connects the water source and the water purifier 3, so that water from the external water source enters the water purifier 3 through the diverter 1, and the pure water inlet 41 and the water inlet 211 are connected to the water outlet chamber 1148, so that the pure water purified by the water purifier 3 can enter the faucet 4 and the tankless pipeline machine 2 through the diverter 1, so that the user can use it through different use ends.

[0059] See also Figures 2 to 4 The tankless pipeline machine 2 includes a housing 21, a water system 22, an instant heating device 25 and a water outlet pipe 29. Figure 2 and Figure 3The shell 21 has a water inlet 211 and a water outlet 212, wherein the shell 21 may include a first shell and a second shell, wherein the first shell and the second shell may be detachably connected by means of snap connection, screw connection, etc. The first shell and the second shell enclose an installation cavity 215. The water system 22, the instant heating device 25, and the water outlet pipe 29 are all installed in the installation cavity 215. The water system 22 is used to supply water to the instant heating device 25, wherein the water tankless pipeline machine 2 also includes an electronic control device 24, and the electronic control device 24 is used to control the working conditions of the water system 22 and the instant heating device 25. Through preset programs and algorithms, the electronic control device 24 can accurately adjust parameters such as water flow rate and water temperature to meet different needs of users.

[0060] It should be noted that the water inlet 211 and the water outlet 212 may be in the form of a pipe integrally formed on the housing 21, or may be in the form of a separate component, such as a hose or a joint. A avoidance opening is formed on the first housing and / or the second housing, and the components forming the water inlet 211 and / or the water outlet 212 may at least partially pass through the avoidance opening and extend into the installation cavity 215, and be connected to other components in the installation cavity 215.

[0061] In order to optimize the thermal management of the tankless pipeline machine 2 and avoid unnecessary heat transfer between the electronic control device 24 and the instant heating device 25, please refer to Figure 3 and Figure 4 In some embodiments, the installation cavity 215 includes a strong current installation area 214 and a weak current installation area. In the length direction of the water tankless pipeline machine 2, the strong current installation area 214 and the weak current installation area are spaced apart, wherein the electric control device 24 is installed in the strong current installation area 214, and the instant heating device 25 is installed in the weak current installation area. The strong current installation area 214 is also the electric control installation area 213 for installing the electric control device 24. It can be understood that the instant heating device 25 needs strong power supply, and strong power has the characteristics of high voltage and large current; the electric control device 24 needs weak power supply, and weak power has the characteristics of low voltage and small current. Therefore, in the length direction of the water tankless pipeline machine 2, the electric control device 24 and the instant heating device 25 are spaced apart. In this way, electromagnetic interference can be reduced to ensure the stability and reliability of the electrical signal on the electric control device 24.

[0062] For further information, see Figure 3 and Figure 4The high-voltage installation area 214 includes a water channel installation area 2141 and an instant heating installation area 2142 which are arranged in sequence in the length direction. The electric control installation area 213 and the instant heating installation area 2142 are respectively located on both sides of the water channel installation area 2141. This can avoid unnecessary heat transfer superposition between the electric control device 24 and the instant heating device 25. It can be understood that the instant heating device 25 requires high-voltage power supply, and high voltage has the characteristics of high voltage and large current; the electric control device 24 requires low-voltage power supply, and low voltage has the characteristics of low current. Therefore, in the length direction of the water tankless pipeline machine 2, the electric control device 24 and the instant heating device 25 are spaced apart. In this way, electromagnetic interference can be reduced to ensure the stability and reliability of the electrical signal on the electric control device 24.

[0063] Please return to Figure 1 , wherein the water circuit system 22 includes a hot water circuit 221 and a normal temperature circuit 222, wherein the hot water circuit 221 is used to provide hot water, and the normal temperature circuit 222 is used to provide normal temperature water. The hot water circuit 221 includes a first water inlet solenoid valve 2211 and a pump assembly 2212, and the first water inlet solenoid valve 2211 is connected to the water inlet 211. The water inlet end of the normal temperature circuit 222 is connected to the water inlet 211, and the water outlet end is connected to the hot water circuit 221 and is located downstream of the pump assembly 2212, and the normal temperature circuit 222 is provided with a second water inlet solenoid valve 2221. Specifically, since the hot water circuit 221 is provided with a water pump 2214, the water flow rate of the hot water circuit 221 is relatively small, but it is sufficient to meet the immediate demand for daily hot water. The normal temperature water circuit 222 cleverly bypasses the pump assembly 2212 and directly controls the on-off of the water circuit through the second water inlet solenoid valve 2221, so that the water flow rate can be relatively increased, fully meeting the use scenario of large water volume. In addition, even when the instant heating device 25 is not started to heat hot water, normal temperature water will continue to flow through the instant heating device 25, which not only maintains the dynamic circulation of the water circuit of the instant heating device 25, but also significantly reduces the risk of bacterial growth, ensuring the hygiene and safety of water use.

[0064] See also Figure 3 and Figure 4 In order to facilitate the installation of the hot water circuit 221 in the housing 21, the first water inlet solenoid valve 2211 and the pump assembly 2212 are arranged side by side in the length direction in the water circuit installation area 2141; the water inlet end of the instant heating device 25 is connected to the water outlet end of the pump assembly 2212; the water inlet end of the outlet pipe 29 is connected to the water outlet end of the instant heating device 25, and the instant heating device 25 and the outlet pipe 29 are arranged side by side in the instant heating installation area 2142 in the thickness direction of the housing 21. Further, the normal temperature water circuit 222 can also be installed in the water circuit installation area 2141, and the second water inlet solenoid valve 2221 can be arranged side by side with the first water inlet solenoid valve 2211 in the length direction in the water circuit installation area 2141, or can be arranged side by side in the height direction in the water circuit installation area 2141, and this application does not limit this.

[0065] The water tankless pipeline machine 2 based on the embodiment of the present application is designed without a water tank, so it will not take up too much space. The overall size of the pipeline machine is smaller and can be installed in a smaller area, making the installation more flexible. Moreover, since the water tankless pipeline machine 2 does not need to store water, there is no need to maintain the water temperature in the water tank, which reduces energy consumption. It can also avoid problems such as dirt and grime easily hidden inside the traditional water tank, severe odor, and bacterial growth, thereby ensuring the purity of the output water and improving the quality of drinking water.

[0066] Since it is designed without a water tank, the hot water circuit 221 needs to be provided with a first water inlet solenoid valve 2211 and a pump assembly 2212. The first water inlet solenoid valve 2211 is responsible for controlling the on and off of the water flow, and the pump assembly 2212 is responsible for providing the power of the water flow. It is understandable that the first water inlet solenoid valve 2211 and the pump assembly 2212 are relatively large in size. In this application, the first water inlet solenoid valve 2211 and the pump assembly 2212 are arranged side by side in the length direction of the housing 21, while the volume of the water outlet pipe 29 is relatively small. In this application, the instant heating device 25 and the water outlet pipe 29 are arranged side by side in the thickness direction of the housing 21, and the first water inlet solenoid valve 2211 and the pump assembly 2212 are arranged in the water circuit installation area 2141, and the instant heating device 25 and the water outlet pipe 29 are arranged in the instant heating installation area 2142. The installation layout provided in the present application can, firstly, space the water system 22 and the instant heating device 25 to avoid the heat generated by the instant heating device 25 affecting the operation of the water system 22; secondly, make the structure inside the entire shell 21 compact, save space, and be conducive to the miniaturization and lightweight of the equipment. For example, if the water outlet pipe 29 and the instant heating device 25 are arranged side by side in the length direction of the shell 21, it is easy to make the length of the shell 21 longer; thirdly, it can take into account the equipment repair or maintenance of the water system 22.

[0067] It should be noted that the first shell and the second shell of the present application are enclosed and fixedly connected in the horizontal direction, and after the first shell is disassembled, the equipment of the water system 22 and the instant heating device 25 are arranged side by side in the second shell. In this way, the internal equipment can be seen at a glance, which is convenient for maintenance or replacement. When installed and used, the second shell is hung on the wall. In this way, there is no need to remove the water tankless pipeline machine 2 as a whole, and the parts in the installation cavity 215 can be directly maintained or repaired after disassembling the first shell. Further explanation, based on the installation environment, the back of the water tankless pipeline machine 2 is attached to the wall, and the second shell can be in the form of a cover shell with an opening on the front side, and the first shell forms a cover structure and covers the opening.

[0068] Please refer to Figures 7 to 9In some embodiments, the pump assembly 2212 may include a flow control pump 2213 and a water pump 2214. When the pump assembly 2212 includes the water pump 2214, the hot water circuit 221 also includes a negative pressure valve 2217. The negative pressure valve 2217 is arranged in the water circuit installation area 2141. The negative pressure valve 2217 communicates with the first water inlet solenoid valve 2211 and the water pump 2214 and is located between the first water inlet solenoid valve 2211 and the water pump 2214. When the water flow in the water circuit system 22 is cut off or the water pump 2214 stops working, the negative pressure valve 2217 can prevent the generation of negative pressure (i.e., pressure lower than atmospheric pressure) in the pipeline. Negative pressure may cause pipeline rupture, water hammer phenomenon (pressure shock caused by sudden stop or change of direction of water flow) or other damage. The negative pressure valve 2217 can maintain positive pressure in the pipeline or at least prevent the generation of negative pressure, thereby protecting the water pump 2214 and other components in the water circuit system 22 from damage. There are many ways for the negative pressure valve 2217 to prevent the generation of negative pressure, such as air filling method, pre-pressure method, etc. The specific structure and principle of the negative pressure valve 2217 have been disclosed in the relevant technology, and this application will not repeat them.

[0069] Of course, when the pump assembly 2212 is a flow control pump, the negative pressure valve 2217 may not be provided. A flow control pump is a pump that can maintain a constant pressure when the flow rate changes. The flow control pump can stabilize the fluid state in the delivery pipeline by accurately controlling the flow rate and pressure of the water flow. In some cases, when the water flow in the delivery pipeline is cut off, the flow control pump can adjust its output flow rate to keep the fluid pressure in the pipeline within a stable range, thereby avoiding the occurrence of negative pressure.

[0070] See also Figure 3 to Figure 4 In some embodiments, the hot water circuit 221 further includes a flow meter 2216, which is installed in the water circuit installation area 2141, wherein the flow meter 2216 can be arranged between the water inlet 211 and the first water inlet solenoid valve 2211; or, between the first water inlet solenoid valve 2211 and the water pump; or, between the water pump and the instant heating device 25. The flow meter 2216 is used to measure the flow rate of water flow and provide accurate water use data for the user. By statistically analyzing the data collected by the flow meter 2216, the user can understand the water use pattern of the tankless pipeline machine 2.

[0071] See also Figure 3 to Figure 4In some embodiments, the hot water circuit 221 further includes a water volume sensor 2215, which is installed in the water circuit installation area 2141, and the water volume sensor 2215 can be arranged between the water inlet 211 and the first water inlet solenoid valve 2211; or, between the first water inlet solenoid valve 2211 and the water pump; or, between the water pump and the instant heating device 25. The instant heating device 25 is configured to reduce power or stop working when the value detected by the water volume sensor 2215 is lower than a preset value. The water volume sensor 2215 can monitor the water volume in the water circuit system 22 in real time, and stop or reduce the power of the instant heating device 25 in time when the water volume is insufficient, so as to prevent the occurrence of dry burning and protect the safety of the equipment. By intelligently controlling the power of the instant heating device 25, the water volume sensor 2215 can achieve energy saving and power saving effects, and reduce the user's electricity cost.

[0072] See also Figure 3 to Figure 4 In some embodiments, in the direction of water flow, the first water inlet solenoid valve 2211, the negative pressure valve 2217, the water volume sensor 2215, the flow meter 2216 and the water pump are connected in sequence; wherein, the first water inlet solenoid valve 2211 and the negative pressure valve 2217 are arranged at intervals in the height direction of the housing 21, the water volume sensor 2215, the flow meter 2216 and the water pump are arranged at intervals in the height direction of the housing 21, and are located between the whole formed by the first water inlet solenoid valve 2211 and the negative pressure valve 2217 and the whole formed by the instant heating device 25 and the water outlet pipe 29, and the water pump is located below the water volume sensor 2215 and the flow meter 2216. The first water inlet solenoid valve 2211, the negative pressure valve 2217, the water volume sensor 2215, the flow meter 2216 and the water pump are partitioned according to their functions, so that the role of each component is clearer. When a fault occurs, the problem can be quickly located, which is convenient for maintenance and repair.

[0073] See also Figure 3 and Figure 4 In some embodiments, the housing 21 includes a shell 216 and a mounting frame 217, wherein the shell 216 includes the first shell and the second shell mentioned above, and has a mounting cavity 215; the mounting frame 217 is fixedly connected to the shell 216 and fixed in the mounting cavity 215, and the first water inlet solenoid valve 2211, the negative pressure valve 2217, the water volume sensor 2215, the flow meter 2216 and the water pump are all mounted on the mounting frame 217. In this way, each component can be installed on the mounting frame 217 first, and then the mounting frame 217 can be installed in the mounting cavity 215, making the assembly process simpler and faster, reducing the difficulty and cost of installation. When a component fails or needs maintenance, the mounting frame 217 can be taken out as a whole, so that the water system 22 can be taken out to observe the location of the fault, which is convenient for replacing and maintaining components.

[0074] See also Figure 5 and Figure 6 In some embodiments, the tankless pipeline machine 2 further includes a sterilizing device 23, which is disposed on the outlet pipe 29 and sterilizes the water in the outlet pipe 29. The sterilizing device 23 may be an ultraviolet sterilizer or an ozone sterilizer, etc. Such a sterilizing device 23 can effectively sterilize without producing chemical residues, thereby reducing pollution to the environment. The sterilizing device 23 can effectively kill microorganisms such as bacteria and viruses in the outlet pipe 29, ensure the safety and sanitation of the water quality, and effectively reduce health problems caused by water quality problems.

[0075] See also Figures 2 to 4 ,as well as Figure 5 In some embodiments, the water outlet 212 is arranged at the bottom of the housing 21; the water inlet end of the instant heating device 25 is located below the instant heating device 25, and the water outlet end is located above the instant heating device 25. Specifically, the water outlet 212 is located at the bottom of the housing 21, which is convenient for users to take water, especially for low spaces or children. The water inlet end and the water outlet end of the instant heating device 25 are located below and above it, respectively, which can improve the utilization rate of the space. In detail, since the water outlet 212 is located at the bottom of the housing 21, the water outlet of the water outlet pipe 29 is provided with a sterilization device 23, and considering the parallel arrangement of the water outlet pipe 29 and the instant heating device 25, the water inlet end of the water outlet pipe 29 is arranged above, so that the water inlet end and the water outlet end of the instant heating device 25 are located below and above it, respectively, so as to adapt to the arrangement direction of the water outlet pipe 29.

[0076] The arrangement of the above-mentioned water system 22 is also adapted to the direction of the water path in the instant heating installation area 2142. Specifically, the water inlet 211 is arranged at the bottom of the shell 21, and the first water inlet solenoid valve 2211 and the negative pressure valve 2217 are spaced apart in the height direction. The water volume sensor 2215, the flow meter 2216 and the water pump are also spaced apart in the height direction. After the water from the water source enters the water system 22 from the water inlet 211, it first passes through the first water inlet solenoid valve 2211 and the negative pressure valve 2217. At this time, the water flows upward, and then passes through the water volume sensor 2215, the flow meter 2216 and the water pump. At this time, the water flows downward, and then enters the instant heating device 25, flows upward again, and then flows downward through the water outlet pipe 29, and finally flows out from the water outlet 212.

[0077] In the present application, through reasonable layout of components, the space in the housing 21 can be fully utilized, making the overall device more compact, the water flow can achieve smooth flow and efficient heating, and the components inside the device can be easily maintained and repaired, thereby improving the practicality of the tankless pipeline machine 2. The first water inlet solenoid valve 2211, the flow control pump, the water volume sensor 2215 and the flow meter 2216 are all installed in the waterway installation area 2141, and the instant heating device 25 is installed in the instant heating installation area 2142. In the length direction of the tankless pipeline machine 2, the waterway installation area 2141 is located between the electric control installation area 213 and the instant heating installation area 2142; that is, in the length direction of the tankless pipeline machine 2, the electric control device 24, the waterway system 22 and the instant heating device 25 are arranged side by side, and a thermal isolation barrier is formed by the waterway system 22 to separate the electric control device 24 and the instant heating device 25, thereby reducing the mutual interference of thermal energy.

[0078] See also Figure 6 In some embodiments, the water system 22 further includes a check valve 2218, which is disposed on the water outlet nozzle 212 and prevents water from flowing back in the pipe, thereby protecting other components in the water system 22, such as the water pump, the instant heating device 25, etc., from the impact and damage of the reverse water flow. When the water tankless pipeline machine 2 uses the instant heating device 25 to heat the water in the water system 22, since the instant heating device 25 heats rapidly, it is difficult for the instant heating device 25 to heat the water in the water system 22 to 100 degrees Celsius. Therefore, the check valve 2218 designed at the water outlet nozzle 212 in the embodiment of the present application can play a pressure-bearing role, so as to increase the boiling point of the water in the water outlet pipe 29, thereby making the water boil. In the process of water boiling, water vapor can be discharged from the water outlet pipe 29, and since the water outlet pipe 29 is connected to the water outlet nozzle 212, the water outlet nozzle 212 can discharge the water vapor, so that a stable water column can flow out of the water outlet nozzle 212.

[0079] See also Figure 2 and Figure 6 In some embodiments, the tankless pipeline machine 2 further includes an illumination lamp 28, which is disposed on the housing 21 and is disposed toward the water storage area of ​​the tankless pipeline machine 2, so that the light emitted by the illumination lamp 28 is irradiated on the water storage area, which is located below the water outlet 212. The illumination lamp 28 can illuminate the water storage area, so that the user can clearly see the water level, water quality, and whether there are impurities in the water container even in a dimly lit environment, thereby ensuring the accuracy and safety of water extraction. In addition, the illumination of the illumination lamp 28 helps the user to more intuitively check the cleanliness of the water storage area and the water outlet 212, thereby reminding the user to clean and maintain them in time to ensure water hygiene.

[0080] See also Figure 2In some embodiments, the tankless pipeline machine 2 further includes a display device 27, which is disposed on the housing 21 to display the working information of the tankless pipeline machine 2. The display device 27 can display the working status of the tankless pipeline machine 2 in real time and intuitively, such as water temperature, working status (heating, water discharge, standby, etc.), and possible fault prompts, etc., so that users can better understand the working status of the equipment, thereby reasonably arranging the use time and frequency to avoid unnecessary energy waste. For example, when the water temperature is low, the required heating time is long, and the user can arrange other work first, avoiding wasting time waiting for the water temperature to rise.

[0081] In some embodiments, the display device 27 and the irradiation lamp 28 are both installed in the instant hot installation area 2142, so that the display device 27 and the irradiation lamp 28 can be close to each other. Since the display device 27 and the irradiation lamp 28 are close to each other, in the embodiment of the present application, the display device 27 and the irradiation lamp 28 are electrically connected, and the display device 27 is also used to power the irradiation lamp 28 and directly control the opening and closing of the irradiation lamp 28, which helps to simplify the wiring complexity in the tankless pipeline machine 2.

[0082] It is understandable that the amount of water purified by the water purifier 3 is large, while the water tankless pipeline machine 2 is limited by the heating efficiency of its instant heating device 25 and has a small water consumption. The water outlet chamber 1148 of the diverter 1 of the present application is connected to the water inlet chamber 1147 through the reflux chamber 1146. That is to say, the amount of water flowing from the water purifier 3 to the water outlet chamber 1148 is too large. When the water pressure in the water outlet chamber 1148 is relatively large, the water in the water outlet chamber 1148 can flow back to the water inlet chamber 1147 through the reflux chamber 1146, and enter the water purifier 3 again through the water inlet chamber 1147. In this way, the pressure-bearing capacity of the diverter 1 and the water tankless pipeline machine 2 can be reduced, and the service life of the diverter 1 and the water tankless pipeline machine 2 can be increased.

[0083] Next, the diverter 1 is introduced with reference to the accompanying drawings.

[0084] See also Figures 7 to 9The 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.

[0085] In this embodiment, please refer to Figures 7 to 10As 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. The raw water inlet 1141 is connected to the water inlet chamber 1147, the raw water outlet 1142 is connected to the reflux chamber 1146, and the pure water inlet 1143, the first water supply port 1144, and the second water supply port 1145 are all connected to the water outlet chamber 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.

[0086] Furthermore, if Figures 9 to 11 As shown, the diverter 1 includes a pressure regulating component 16, a diverter component 17 and a one-way flow guide 13. The pressure regulating component 16 is arranged in the water inlet chamber 1147, the diverter component 17 is arranged in the water outlet chamber 1148, and the one-way flow guide 13 is arranged in the return chamber 1146. In this way, the tap water supplied by the water supply pipeline flows into the water inlet chamber 1147 from the raw water inlet 1141. If the water pressure in the urban water supply network changes due to various factors (such as water consumption peak and valley, maintenance and adjustment of the water supply system, etc.), for example, the water pressure is low during the peak water supply stage, and the water pressure is relatively high during the low water consumption period such as at night. At this time, the pressure regulating component 16 will be able to reduce the pressure / stabilize the tap water flowing into the water inlet chamber 1147 into stabilized water, and then output it to the water purifier through the raw water outlet 1142 for filtration and purification, stabilizing the water pressure of the tap water within a suitable range to avoid the risk of overpressure damage or leakage of the water purifier caused by high water pressure on the filter element, water purification pipeline and other precision parts inside the water purifier, thereby increasing the service life of the water purifier. In addition, the tap water passes through the filter element of the water purifier at a relatively stable flow rate, so that the filter element can fully absorb impurities such as organic matter and residual chlorine in the tap water, ensuring that the water purifier always maintains the best filtering effect.

[0087] It can be understood that the water purifier generates pure water after deep filtration and purification of the stabilized water, which flows through the pure water inlet 1143 of the diverter 1 again and flows into the water outlet chamber 1148. Through the cooperation between the water outlet chamber 1148 and the diverter assembly 17, the pure water can be actually allocated and flow out from the first water supply port 1144 to the tankless pipeline machine, and from the second water supply port 1145 to the faucet. During the diversion of the pure water, the excess pure water in the water outlet chamber 1148 can flow back to the reflux chamber 1146 under the regulation of the diverter assembly 17 to form excess water. The reflux chamber 1146 can merge the stabilized water after the pressure is stabilized by the pressure regulating assembly 16 with the excess water refluxed by the diverter assembly 17, and output it to the water purifier from the raw water outlet 1142. The one-way flow guide 13 allows the water in the reflux chamber 1146 to flow in a one-way manner, thereby preventing the water in the reflux chamber 1146 or the water inlet chamber 1147 from flowing back to the water outlet chamber 1148 .

[0088] Next, the specific structure of the above-mentioned flow dividing component 17 is described in detail with reference to the accompanying drawings.

[0089] See also Fig. 9 and Fig.10 The flow diversion 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 flow diversion component 17 and enter the water outlet chamber 1148. Fig.17 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 the 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.

[0090] Please refer to Fig.11The valve housing 11 has a reflux guide portion 1171 , which is located inside the water outlet cavity 1148 , and a guide 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] Please refer to the specific Fig.12 As 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.

[0099] 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.

[0100] 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 shunt component 17 at the same time.

[0101] Next, the specific structure of the above-mentioned flow dividing component 17 is described in detail with reference to the accompanying drawings.

[0102] Please refer to the specific Fig.10 and Fig.12 As 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.

[0103] Among them, see Fig.12 , 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.

[0104] 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 flexible check portion 1721 to seal the guide flow channel 1172. Such settings will have the following unexpected effects:

[0105] 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.

[0106] 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.

[0107] 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.

[0108] It should be added that the specific Fig.12 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 12 to 15 The flexible check portion 1721 includes a duckbill deformation portion 17211 and a base portion 17212 fixedly connected to the shunt balancing membrane 172. The duckbill deformation portion 17211, the base portion 17212, and the shunt balancing membrane 172 are integrally formed to facilitate processing and manufacturing, and can also ensure the integrity of the shunt balancing membrane 172, so that the shunt balancing membrane 172 has good comprehensive performance (such as elasticity, etc.). The duckbill deformation portion 17211 is formed from the base portion 1721 2 is convexly arranged toward the water outlet upper cavity 11482, and the cross-sectional area of ​​the duckbill deformation portion 17211 gradually decreases along the convex direction, and the cross-sectional area here is parallel to the large surface of the diverter balancing membrane 172, and the large surface of the diverter balancing membrane 172 is the side surface with the largest area in the diverter balancing membrane 172, and the flow regulating port 1722 is arranged on the end of the duckbill deformation portion 17211 away from the diverter balancing membrane 172, and the duckbill cavity 1723 is connected to the flow regulating port 1722.

[0109] As a preferred method of this embodiment, please refer to Figures 12 to 16As 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. Fig.15 and Fig.16 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.

[0110] Further, please refer to Fig.10 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.

[0111] Preferably, please combine Fig.12As 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.

[0112] The unexpected effect is that Fig.12 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.

[0113] Further, please refer to Fig.12 As shown, the stop limit portion 1733 is provided with an escape opening 1735 corresponding to the flexible non-return portion 1721. The escape 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:

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] As another preferred method of this embodiment, please refer to Fig.12As 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.

[0120] 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.

[0121] For further details, please refer to Fig.12 As 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.

[0122] It should be noted that if Fig.13 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.

[0123] As another preferred method of this embodiment, please refer to Fig.13 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.

[0124] 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.

[0125] Furthermore, please combine Figures 12 to 16As 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.

[0126] 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.

[0127] 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.

[0128] It should also be noted that if Fig.16As shown, the diameter of the water through hole 1751 gradually increases along the direction of water flow. According to the above description, it can be known that 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 one 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 flow 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 gradually increases, the purified water has enough space to smoothly transition, reducing the turbulence caused by sudden spatial changes, thereby effectively avoiding the generation of small bubbles in the purified water. In addition, the smaller diameter side can also limit the impact of the water flow, thereby reducing physical damage to the water through hole 1751 and the diversion balance membrane 172, such as scratches.

[0129] 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 Fig.16 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.

[0130] 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.

[0131] Further, please refer to Figures 12 to 16 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.

[0132] Specifically, Fig.17 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.

[0133] Preferably, if Fig.17As 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.
