The water purifier has a raw water inlet and a pure water outlet; the tankless water dispenser has an inlet; the faucet has a pure water inlet; the diverter has an inlet chamber connecting the water source and the raw water inlet, an outlet chamber connecting the pure water outlet, the inlet, and the pure water inlet, and a return chamber connecting the outlet chamber and the inlet chamber.

[0006] In some embodiments, the tankless water dispenser includes a housing and a water system. The housing has the inlet and the outlet. The water system is disposed inside the housing and located between the inlet and the outlet. It includes a first inlet solenoid valve, a pump assembly, and a water volume sensor. The first inlet solenoid valve and the pump assembly are arranged sequentially along the direction of water flow.

[0007] The water volume sensor is located between the water inlet and the first water inlet solenoid valve; or between the first water inlet solenoid valve and the pump assembly; or between the pump assembly and the water outlet.

[0008] In some embodiments, the pump assembly includes a water pump or a flow control pump, and when the pump assembly includes the water pump, the water system further includes:

[0009] A negative pressure valve connects the first inlet solenoid valve and the water pump, and is located between the first inlet solenoid valve and the water pump.

[0010] In some embodiments, the water system further includes:

[0011] A flow meter is disposed between the water inlet and the first water inlet solenoid valve; or, disposed between the first water inlet solenoid valve and the pump assembly; or, disposed between the pump assembly and the water outlet.

[0013] A check valve is installed at the water outlet to prevent water from dripping from the water outlet.

[0014] In some embodiments, the tankless water dispenser further includes:

[0015] An instant heating device is installed between the water system and the water outlet, and connects the water system and the water outlet.

[0016] In some embodiments, the tankless water dispenser further includes:

[0017] A sterilization device is disposed between the instant heating device and the water outlet, or disposed upstream of the instant heating device.

[0018] In some embodiments, the tankless water dispenser further includes:

[0019] A water outlet pipe connects the instant heating device and the water outlet nozzle, and the sterilization device is installed on the water outlet pipe.

[0020] In some embodiments, the housing has a water-cooled mounting area and an instant-heat mounting area arranged in the longitudinal direction;

[0021] The first inlet solenoid valve and the pump assembly are arranged side by side in the water circuit installation area along the length direction, and the instant heating device and the outlet pipe are arranged side by side in the instant heating installation area along the thickness direction of the housing.

[0022] In some embodiments, the housing is further provided with:

[0023] The electrical control installation area is located on the side of the water circuit installation area away from the instant heating installation area;

[0024] The tankless water dispenser also includes an electrical control device, which is located in the electrical control installation area and is electrically connected to the first water inlet solenoid valve, the pump assembly, and the instant heating device to control the opening and closing of the water inlet solenoid valve, the pump assembly, and the instant heating device.

[0029] Based on the water purification system of this application embodiment, the water purifier supplies water to the tankless water dispenser and faucets via a distributor, facilitating water use at different points of contact. The distributor is equipped with a return chamber, allowing water in the outlet chamber to flow back to the inlet chamber when the water purifier delivers a large flow rate, and then back to the water purifier, reducing the pressure load on the distributor and the tankless water dispenser, thereby enhancing the stability of the entire water purification system. The purified water produced by the water purifier through the distributor can be directly supplied to the tankless water dispenser without prior storage in a tank, avoiding… The retention of purified water in the tank ensures immediate and efficient use of the purified water. Since the tankless water dispenser does not require a large water tank, the overall size of the water purification system is reduced, making it more suitable for use in places with limited space, such as home kitchens and office tea rooms. Moreover, the absence of a water tank reduces bacterial growth, ensuring that the water quality for users is purer and safer. In this application, users can directly obtain purified water through the tap, improving the convenience of water access. At the same time, the tankless water dispenser can also provide hot water instantly, meeting the diverse drinking water needs of users. Attached Figure Description

[0045] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0046] To make the objectives, technical solutions and advantages of this utility model clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0047] Where the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this invention as detailed in the appended claims.

[0048] In the description of this utility model, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances. Furthermore, in the description of this utility model, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0050] Water purification systems are mainly used in home kitchens, office tea rooms, and other places to provide people with safe, healthy, and convenient drinking water and domestic water.

[0051] However, a common problem exists with current water purification systems on the market: the purified water from water purifiers is mainly supplied to water dispensers, resulting in a single type of drinking water device that fails to meet diverse user needs. Furthermore, for instant water dispensers, the amount of water that can be heated is limited by the heating power of the instant heating device. In contrast, water purifiers have a much larger water output, far exceeding the flow limit of instant heating devices. Therefore, to accommodate the high flow rate of water purifiers, water dispensers typically require a water tank as a buffer storage device before a pump draws water from the tank to the heating system for heating.

[0052] The water purification efficiency of this type of water purifier system is not only difficult to fully utilize, but the large size of the water tank is also a key factor restricting the reduction of the overall size of the machine. In addition, the water tank is also prone to bacterial growth.

[0053] Please see Figure 1 This application proposes a water purification system, including a tankless water dispenser 2, a water purifier 3, 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 water dispenser 2 has an inlet 211; and the faucet 4 has a pure water inlet 41. The diverter 1 has an inlet chamber 1147, an outlet chamber 1148, and a return chamber 1146. The inlet chamber 1147 connects to the water source and the raw water inlet 31, the outlet chamber 1148 connects to the pure water outlet 32, the inlet 211, and the pure water inlet 41, and the return chamber 1146 connects the outlet chamber 1148 and the inlet chamber 1147. Water from the source enters the water purifier 3 through the inlet chamber 1147 and the raw water inlet 31 for purification, and then enters the outlet chamber 1148 through the pure water outlet 32. It can selectively enter the tankless water dispenser 2 and / or the faucet 4 through the outlet chamber 1148. When the water volume in the outlet chamber 1148 is large, it can flow back to the inlet chamber 1147 through the return chamber 1146 and re-enter the water purifier 3, thereby reducing the pressure of the distributor 1 and the tankless water dispenser 2.

[0054] In this application, the diverter 1 allows multiple water outlets to share a single water purifier 3, thereby saving kitchen or home space. This is more economical than installing a separate water purifier at each water outlet, reducing installation costs and long-term maintenance and replacement costs. Users can conveniently obtain purified water from different water outlets, improving the convenience and flexibility of water use.

[0055] Existing pipeline machines require a water tank and are relatively large in size. Based on this, this application proposes a smaller and more compact tankless pipeline machine 2, which will be described in detail below.

[0056] Please see Figures 2 to 4 The tankless water dispenser 2 includes a housing 21, a water system 22, an instant heating device 25, and a water outlet pipe 29. Please refer to [link / reference needed]. Figure 4 The housing 21 has a water inlet 211 and a water outlet 212. The housing 21 may include a first housing and a second housing, which can be detachably connected by snap-fit, screw connection, or other means. The first and second housings together form an installation cavity 215. The water system 22, the instant heating device 25, and the water outlet pipe 29 are all installed within the installation cavity 215. The water system 22 supplies water to the instant heating device 25. The tankless water dispenser 2 also includes an electronic control device 24, which controls the operating 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 user needs.

[0057] It should be noted that the aforementioned inlet 211 and outlet 212 can be integrally formed on the housing 21 as pipes, or they can be separate components, such as hoses or connectors. The first and / or second housings have clearance openings, allowing the components forming the inlet 211 and / or outlet 212 to at least partially pass through the clearance openings and extend into the mounting cavity 215, connecting with other components within the mounting cavity 215.

[0058] Please see Figure 3 and Figure 4To optimize the thermal management of the tankless water dispenser 2 and avoid unnecessary heat transfer and superposition between the electrical control device 24 and the instant heating device 25, in some embodiments, the mounting cavity 215 includes a high-voltage installation area 214 and a low-voltage installation area. Along the length of the tankless water dispenser 2, the high-voltage installation area 214 and the low-voltage installation area are spaced apart. The electrical control device 24 is installed in the high-voltage installation area 214, and the instant heating device 25 is installed in the low-voltage installation area. The high-voltage installation area 214 is also the electrical control installation area 213 used to install the electrical control device 24. It is understood that the instant heating device 25 requires high-voltage power, which is characterized by high voltage and large current; the electrical control device 24 requires low-voltage power, which is characterized by low voltage and small current. Therefore, by spaced apart along the length of the tankless water dispenser 2, electromagnetic interference can be reduced, ensuring the stability and reliability of the power signal on the electrical control device 24.

[0059] Please continue reading. Figure 3 and Figure 4 Furthermore, the high-voltage installation area 214 includes a water circuit installation area 2141 and an instant heating installation area 2142 arranged sequentially along the length direction. The electrical control installation area 213 and the instant heating installation area 2142 are located on both sides of the water circuit installation area 2141, respectively. This avoids unnecessary heat transfer and superposition between the electrical control device 24 and the instant heating device 25. It is understood that the instant heating device 25 requires high-voltage power supply, and high-voltage power has the characteristics of high voltage and large current; the electrical control device 24 requires low-voltage power supply, and low-voltage power has the characteristics of low voltage and small current. Therefore, the electrical control device 24 and the instant heating device 25 are arranged alternately along the length direction of the tankless water dispenser 2. In this way, electromagnetic interference can be reduced to ensure the stability and reliability of the power-on signal of the electrical control device 24.

[0060] Please refer to it again. Figure 3 and Figure 4 The water system 22 includes a first inlet solenoid valve 2211 and a pump assembly 2212. The first inlet solenoid valve 2211 is connected to the inlet 211. The first inlet solenoid valve 2211 and the pump assembly 2212 are arranged side by side in the water installation area 2141 along the length direction. The inlet end of the instant heating device 25 is connected to the outlet end of the pump assembly 2212. The inlet end of the outlet pipe 29 is connected to the outlet end of the instant heating device 25. The instant heating device 25 and the outlet pipe 29 are arranged side by side in the instant heating installation area 2142 along the thickness direction of the housing 21.

[0061] The tankless water dispenser 2 based on the embodiments of this application, due to its tankless design, does not occupy too much space. The overall size of the dispenser is more compact, and it can be installed in a smaller area, making installation more flexible. Furthermore, since the tankless water dispenser 2 does not need to store water, there is no need to maintain the water temperature in the tank, reducing energy consumption. It also avoids problems such as dirt and grime accumulation, strong odor, and bacterial growth inside traditional water tanks, ensuring the purity of the water and improving the quality of drinking water.

[0062] Since it is a tankless design, the water system 22 needs to be equipped with a first inlet solenoid valve 2211 and a pump assembly 2212. The first inlet solenoid valve 2211 is responsible for controlling the flow of water, and the pump assembly 2212 is responsible for providing the power for the water flow. Understandably, the first inlet solenoid valve 2211 and the pump assembly 2212 are relatively large. In this application, the first inlet solenoid valve 2211 and the pump assembly 2212 are arranged side by side along the length of the housing 21. The outlet pipe 29 is relatively small. In this application, the instant heating device 25 and the outlet pipe 29 are arranged side by side along the thickness of the housing 21. The first inlet solenoid valve 2211 and the pump assembly 2212 are located in the water system installation area 2141, and the instant heating device 25 and the outlet pipe 29 are located in the instant heating installation area 2142. The installation layout provided in this application has three advantages: First, it allows the water system 22 and the instant heating device 25 to be set apart, avoiding the heat generated by the instant heating device 25 from affecting the operation of the water system 22. Second, it makes the internal structure of the entire housing 21 compact, saving space and facilitating the miniaturization and weight reduction of the equipment. For example, if the water outlet pipe 29 and the instant heating device 25 are set side by side in the length direction of the housing 21, the length of the housing 21 can be made longer. Third, it can also accommodate the maintenance or repair of the water system 22.

[0063] Please refer to the following: Figures 7 to 9In some embodiments, pump assembly 2212 may include a flow control pump 2213 and a water pump 2214. When pump assembly 2212 includes water pump 2214, water system 22 also includes a negative pressure valve 2217. Negative pressure valve 2217 is disposed in water installation area 2141, connecting the first inlet solenoid valve 2211 and water pump 2214, and is located between the first inlet solenoid valve 2211 and water pump 2214. When the water flow in water system 22 is cut off or water pump 2214 stops working, negative pressure valve 2217 can prevent the generation of negative pressure (i.e., pressure below atmospheric pressure) in the pipeline. Negative pressure may cause pipeline rupture, water hammer (pressure surge due to sudden cessation or change of direction of water flow), or other damage. Negative pressure valve 2217 can maintain positive pressure in the pipeline or at least prevent the generation of negative pressure, thereby protecting water pump 2214 and other components in water system 22 from damage. There are various ways for the negative pressure valve 2217 to prevent the generation of negative pressure, such as the air injection method and the pre-pressurization method. The specific structure and principle of the negative pressure valve 2217 have been disclosed in related technologies, and will not be repeated here.

[0064] Of course, if pump assembly 2212 is a flow control pump 2213, a negative pressure valve 2217 may not be required. The flow control pump 2213 is a pump capable of maintaining a constant pressure when the flow rate changes. By precisely controlling the flow rate and pressure of the water, the flow control pump 2213 can stabilize the fluid state within the delivery pipeline. In certain situations, when the water flow in the delivery pipeline is cut off, the flow control pump 2213 can adjust its output flow rate to maintain the fluid pressure within the pipeline within a stable range, thereby preventing negative pressure from occurring.

[0065] Please see Figures 7 to 9 In some embodiments, the water system 22 further includes a flow meter 2216, which is installed within the water installation area 2141. The flow meter 2216 can be positioned between the inlet 211 and the first inlet solenoid valve 2211; or between the first inlet solenoid valve 2211 and the water pump 2214; or between the water pump 2214 and the instant heating device 25. The flow meter 2216 measures the water flow rate, providing users with accurate water usage data. Statistical analysis of the data collected by the flow meter 2216 can help users understand the water usage patterns of the tankless water dispenser 2.

[0066] Please see Figures 7 to 9In some embodiments, the water system 22 further includes a water volume sensor 2215, which is installed in the water installation area 2141. The water volume sensor 2215 can be positioned between the water inlet 211 and the first inlet solenoid valve 2211; or between the first inlet solenoid valve 2211 and the water pump 2214; or between the water pump 2214 and the instant heating device 25. The instant heating device 25 is configured to reduce its power or stop operating 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 system 22 in real time, and promptly stop or reduce the power of the instant heating device 25 when the water volume is insufficient, preventing dry burning and protecting 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, reducing the user's electricity costs.

[0067] Please see Figures 7 to 9 In some embodiments, the first inlet solenoid valve 2211, negative pressure valve 2217, water volume sensor 2215, flow meter 2216, and water pump 2214 are sequentially connected in the direction of water flow. The first inlet solenoid valve 2211 and negative pressure valve 2217 are spaced apart along the height of the housing 21. The water volume sensor 2215, flow meter 2216, and water pump 2214 are also spaced apart along the height of the housing 21 and are located between the entire assembly formed by the first inlet solenoid valve 2211 and negative pressure valve 2217 and the entire assembly formed by the instant heating device 25 and the outlet pipe 29. The water pump 2214 is located below the water volume sensor 2215 and flow meter 2216. The components such as the first inlet solenoid valve 2211, negative pressure valve 2217, water volume sensor 2215, flow meter 2216, and water pump 2214 are functionally partitioned, making the function of each component clearer. This allows for quick location of the problem in case of a malfunction, facilitating maintenance and repair.

[0068] Please see Figure 3 and Figure 4 In some embodiments, the housing 21 includes an outer shell 216 and a mounting bracket 217. The outer shell 216 includes the aforementioned first shell and second shell, and has a mounting cavity 215. The mounting bracket 217 is fixedly connected to the outer shell 216 and fixed within the mounting cavity 215. The first inlet solenoid valve 2211, the negative pressure valve 2217, the water volume sensor 2215, the flow meter 2216, and the water pump 2214 are all mounted on the mounting bracket 217. This allows each component to be installed on the mounting bracket 217 first, and then the mounting bracket 217 to be installed within the mounting cavity 215, making the assembly process simpler and faster, and reducing installation difficulty and cost. When a component malfunctions or requires maintenance, the mounting bracket 217 can be removed entirely, allowing the water system 22 to be taken out to observe the location of the fault, facilitating component replacement and maintenance.

[0069] Please see Figure 5 and Figure 6 In some embodiments, the tankless water dispenser 2 further includes a sterilization device 23, which is installed on the water outlet pipe 29 and sterilizes the water in the outlet pipe 29. The sterilization device 23 can be in the form of an ultraviolet sterilizer or an ozone sterilizer, etc. This sterilization device 23 can effectively sterilize without producing chemical residues, thereby reducing environmental pollution. The sterilization device 23 can effectively kill bacteria, viruses, and other microorganisms in the water outlet pipe 29, ensuring water safety and hygiene, and effectively reducing health problems caused by water quality issues.

[0070] Please see Figures 3 to 6 In some embodiments, the water outlet 212 is located at the bottom of the housing 21; the water inlet of the instant heating device 25 is located below the instant heating device 25, and the water outlet is located above the instant heating device 25. Specifically, the water outlet 212 is located at the bottom of the housing 21 for easy water access, especially in low-ceilinged spaces or for use by children. The water inlet and water outlet of the instant heating device 25 are located below and above it, respectively, which improves space utilization. In detail, since the water outlet 212 is located at the bottom of the housing 21, the water outlet pipe 29 is equipped with a sterilization device 23. Considering the parallel arrangement of the water outlet pipe 29 and the instant heating device 25, the water inlet of the water outlet pipe 29 is located above it. Therefore, the water inlet and water outlet of the instant heating device 25 are located below and above it, respectively, thus adapting to the arrangement of the water outlet pipe 29.

[0071] The layout of the water system 22 described above is also adapted to the water flow in the instant heating installation area 2142. Specifically, the inlet 211 is located at the bottom of the housing 21. The first 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 2214 are also spaced apart in the height direction. After the water from the water source enters the water system 22 through the inlet 211, it first passes through the first inlet solenoid valve 2211 and the negative pressure valve 2217, at which point the water flows upward. Then it passes through the water volume sensor 2215, the flow meter 2216 and the water pump 2214, at which point the water flows downward. Then it enters the instant heating device 25, flows upward again, then flows downward through the outlet pipe 29, and finally flows out from the outlet 212.

[0072] In this application, through a reasonable component layout, the space inside the housing 21 can be fully utilized, making the overall equipment more compact, enabling smooth water flow and efficient heating, and facilitating the maintenance and repair of the internal components, thereby improving the practicality of the tankless water dispenser 2.

[0073] In this application, the first inlet solenoid valve 2211, the flow control pump 2213, the water volume sensor 2215, and the flow meter 2216 are all installed in the water circuit 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 water dispenser 2, the water circuit installation area 2141 is located between the electrical control installation area 213 and the instant heating installation area 2142. That is, in the length direction of the tankless water dispenser 2, the electrical control device 24, the water circuit system 22, and the instant heating device 25 are arranged side by side, and a thermal isolation barrier is formed by the water circuit system 22 to separate the electrical control device 24 and the instant heating device 25, thereby reducing thermal energy interaction interference.

[0074] Please see Figure 6 and Figure 7 In some embodiments, the water system 22 also includes a check valve 2218, which is installed on the outlet 212 to prevent backflow of water in the pipe and protect other components in the water system 22, such as the water pump 2214 and the instant heating device 25, from the impact and damage of reverse water flow. When the tankless water dispenser 2 uses the instant heating device 25 to heat the water in the water system 22, the instant heating device 25 heats the water rapidly, making it difficult to heat the water in the water system 22 to 100 degrees Celsius. Therefore, the check valve 2218 designed at the outlet 212 in this embodiment can play a pressure-bearing role to increase the boiling point of the water in the outlet pipe 29, thereby causing the water to boil. During the boiling process, water vapor can be released from the outlet pipe 29, and since the outlet pipe 29 is connected to the outlet 212, the outlet 212 can discharge the water vapor, so that a stable water column can flow out of the outlet 212.

[0075] Please see Figure 2 and Figure 6 In some embodiments, the tankless water dispenser 2 also includes an illumination lamp 28, disposed on the housing 21 and facing the water-holding area of ​​the tankless water dispenser 2, so that the light emitted by the illumination lamp 28 illuminates the water-holding area, which is located below the water outlet 212. The illumination lamp 28 can illuminate the water-holding area, allowing users to clearly see the water level, water quality, and whether there are impurities in the water container even in low-light environments, thereby ensuring the accuracy and safety of water dispensing. In addition, the illumination of the illumination lamp 28 helps users to more intuitively check the cleanliness of the water-holding area and the water outlet 212, thereby reminding users to clean and maintain them in a timely manner to ensure water hygiene.

[0076] Please see Figure 4In some embodiments, the tankless water dispenser 2 also includes a display device 27 mounted on the housing 21 to display the operating information of the tankless water dispenser 2. The display device 27 can display the operating status of the tankless water dispenser 2 in real time and intuitively, such as water temperature, operating status (heating, dispensing water, standby, etc.), and possible fault prompts. Users can better understand the equipment's operating status, thereby rationally scheduling usage time and frequency to avoid unnecessary energy waste. For example, when the water temperature is low, the required heating time is longer, and users can schedule other tasks first, avoiding wasted time waiting for the water temperature to rise.

[0077] In some embodiments, both the display device 27 and the illumination lamp 28 are installed within the instantaneous mounting area 2142, thus allowing the display device 27 and the illumination lamp 28 to be positioned close to each other. Because the display device 27 and the illumination lamp 28 are positioned close to each other, in this embodiment, the display device 27 is electrically connected to the illumination lamp 28. The display device 27 also supplies power to the illumination lamp 28 and directly controls the on / off state of the illumination lamp 28, which helps to simplify the wiring complexity within the tankless water dispenser 2.

[0078] Understandably, the water purifier 3 purifies a larger volume of water, while the tankless water dispenser 2, limited by the heating efficiency of its instant heating device 25, uses less water. When the water pressure in the outlet chamber 1148 is high, the water can flow back to the inlet chamber 1147 through the return chamber 1146, thus improving the service life of the distributor 1 and the tankless water dispenser 2. Based on this, this application further improves the distributor 1.

[0079] Please see Figures 10 to 12 The diverter 1 includes a valve housing 11, which comprises an upper valve body shell 116 and a lower valve body shell 117 connected to each other. The upper valve body shell 116 and the lower valve body shell 117 can be assembled using connection methods including but not limited to bolt connections and snap-fit ​​connections. The upper valve body shell 116 and the lower valve body shell 117 together constitute an inlet chamber 1147, a return chamber 1146, and an outlet chamber 1148. The outlet chamber 1148 can communicate with the inlet chamber 1147 through the return chamber 1146. The inlet chamber 1147 and the outlet chamber 1148 are preferably located on the top side of the return chamber 1146. The upper valve body shell 116 is a one-piece molded component, and / or the lower valve body shell 117 is a one-piece molded component. Therefore, the valve housing 11 assembled with the upper valve body shell 116 and the lower valve body shell 117 is more stable and has higher structural strength. In this way, when subjected to high-pressure fluid, the pressure can be evenly distributed in all parts of the valve body 11.

[0080] Please see Figures 10 to 12The diverter 1 is equipped with a raw water inlet 1141, a pure water inlet 1143, a raw water outlet 1142, a first water supply port 1144, and a second water supply port 1145. The raw water inlet 1141 is used to connect to the water supply pipe to introduce tap water into the valve body 11. The raw water outlet 1142 is used to connect to the raw water inlet 31 to deliver pressure-stabilized water to the water purifier 3. The pure water inlet 1143 is used to connect to the pure water outlet 32 ​​to introduce pure water purified by the water purifier 3. The first water supply port 1144 is used to connect to the inlet 211 to deliver pure water to the tankless water dispenser 2. The second water supply port 1145 is used to connect to the pure water inlet to deliver pure water to the faucet 4. The raw water inlet 1141 is connected to the inlet chamber 1147, the raw water outlet 1142 is connected to the return chamber 1146, and the pure water inlet 1143, the first water supply port 1144, and the second water supply port 1145 are all connected to the outlet chamber 1148. Preferably, the raw water outlet 1142, the pure water inlet 1143, and the second water supply port 1145 are all located in the lower shell 117 of the valve body, and the raw water inlet 1141 and the first water supply port 1144 are located in the upper shell 116 of the valve body.

[0081] Please see Figures 10 to 12 The diverter 1 also includes a diverter assembly 17, which is disposed within the outlet chamber 1148 and divides the outlet chamber 1148 into a lower outlet chamber 11481 and an upper outlet chamber 11482. The lower outlet chamber 11481 connects to the pure water outlet 32 ​​and the pure water inlet, the upper outlet chamber 11482 connects to the lower outlet chamber 11481 and the inlet 211, and the return chamber 1146 connects the lower outlet chamber 11481 and the inlet chamber 1147. The diverter assembly 17 can open or close the return chamber 1146 according to the pressure difference between the lower outlet chamber 11481 and the upper outlet chamber 11482.

[0082] Please see Figures 10 to 12 The diversion assembly 17 is provided with a flow passage, and the valve housing 11 has a return guide portion 1171. The return guide portion 1171 has a guide channel 1172 that communicates with the return chamber 1146. The diversion assembly 17 is installed in the outlet chamber 1148 of the valve housing 11, and the diversion assembly 17 can abut against the return guide portion 1171. The flow passage is used to guide the pure water flowing in from the pure water inlet 1143 through the diversion assembly 17 and into the outlet chamber 1148. According to the pressure difference formed by the pure water inlet 1143, the first water supply port 1144, and the second water supply port 1145, the diversion assembly 17 can generate a relative displacement towards the first water supply port 1144, so that the diversion assembly 17 separates from the return guide portion 1171. Then, excess pure water can flow from the guide channel 1172 into the return chamber 1146, forming the aforementioned excess water.

[0083] When the faucet 4 is used alone, the purified water flows into the valve body 11 from the purified water inlet 1143 and then flows out directly from the second water supply port 1145. At this time, the diversion component 17 abuts against and fits on the return guide part 1171 to seal the guide flow channel 1172, so that the purified water will not flow back to the guide flow channel 1172.

[0084] When the tankless water dispenser 2 is used alone, purified water flows in from the purified water inlet 1143, passes through the water passage, enters the outlet chamber 1148, and finally flows out from the first water supply port 1144 to the tankless water dispenser 2. At this time, the pressure on the side of the diversion component 17 near the first water supply port 1144 is less than the pressure on the side of the diversion component 17 away from the first water supply port 1144. That is, the water pressure formed by the purified water inlet 1143 and the second water supply port 1145 is greater than the water pressure on the side of the first water supply port 1144. The diversion component 17 can generate a relative displacement towards the side of the first water supply port 1144, so that the diversion component 17 separates from the return guide part 1171, and the excess purified water flows back to the guide channel 1172. When the tankless water dispenser 2 is turned off, the diversion component 17 will reset towards the side of the return guide part 1171, and the diversion component 17 will abut against the return guide part 1171 again to reseal the guide channel 1172. Therefore, the distributor 1 can flexibly meet the water flow distribution needs of the tankless water dispenser 2 when it uses water alone, so that the purified water can meet the water needs of the tankless water dispenser 2 while reasonably handling the excess water volume, without wasting water resources, and avoiding the risk of damaging the tankless water dispenser 2 due to excessive water pressure.

[0085] When the tankless water dispenser 2 and the faucet 4 use water simultaneously, water flows into the valve housing 11 from the pure water inlet 1143. A portion flows out from the second water supply port 1145 to the faucet 4, while the other portion passes through the water passage into the outlet chamber 1148 and flows out from the first water supply port 1144 to the tankless water dispenser 2. Because the water pressure on the second water supply port 1145 side decreases, the pressure on the side of the diversion assembly 17 near the first water supply port 1144 is not significantly different from the pressure on the side of the diversion assembly 17 away from the first water supply port 1144. At this time, the diversion assembly 17 abuts against the return guide 1171, preventing excess pure water from flowing back into the guide channel 1172. This ensures that both the tankless water dispenser 2 and the faucet 4 can use water normally, and also guarantees the stable operation of the entire water purification system.

[0086] Thus, when the tankless water dispenser 2 is turned on, excess purified water can flow back, preventing the water purifier 3 from frequently adjusting its operating state due to sudden changes in water usage by the tankless water dispenser 2 (such as water pressure changes caused by frequent opening and closing of the tankless water dispenser 2). For example, without a backflow mechanism, when the tankless water dispenser 2 is suddenly turned off, the instantaneous change in water pressure may impact the internal structure and operating pressure of the water purifier 3. With a backflow mechanism, such water pressure changes can be buffered to a certain extent, reducing the pressure of frequent start-stop cycles for the water purifier 3. When water is used simultaneously, the diversion component 17 maintains a relatively stable water flow distribution. Without the diversion component 17, when the faucet 4 and the tankless water dispenser 2 are working simultaneously, a sudden change in water usage by one (such as when the faucet 4 is suddenly turned off) may cause large fluctuations in the internal water pressure of the water purifier 3, leading to frequent adjustments in the operating state of the water purifier 3. The diversion component 17 can maintain a relatively stable water pressure and water flow distribution, reducing the frequent start-stop cycles of the water purifier 3 caused by changes in external water usage.

[0087] The diversion assembly 17 may include a diversion diaphragm with a water passage and a fixing assembly for fixing the diversion diaphragm in the valve housing 11. The diversion diaphragm may be made of a flexible material or have an extension space, so that the diversion diaphragm can deform under changes in water pressure, thereby automatically opening or closing the return chamber 1146.
