[0065] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0066] To make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

[0067] 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 the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0068] In the description of this invention, 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 invention based on the specific circumstances. Furthermore, in the description of this invention, unless otherwise stated, "multiple" refers to two or more.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0069] 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.

[0070] 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.

[0071] Currently, in most water purification systems on the market, the purified water from water purifiers is primarily supplied to water dispensers. However, 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 output, far exceeding the flow rate limit of the instant heating device in water dispensers. Therefore, to accommodate high-flow 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. Water tanks are also prone to bacterial growth, and their large size is a key factor limiting the overall size of the system. Furthermore, the heating efficiency of instant heating devices fluctuates, making it difficult to ensure that the outlet water temperature meets the user's needs.

[0072] This application proposes a drinking water purification system, comprising a water purifier 3, a tankless water dispenser 2, and a faucet 4. The water purifier 3 is used to perform deep filtration and purification treatment on the water source provided by the water supply pipeline, so that the water quality meets the standards for safe drinking or specific usage requirements. The tankless water dispenser 2 is used to heat or cool the purified water source in real time, so that users can accurately obtain drinking water and meet different drinking water temperature requirements. It should be noted that the water purifier 3 and the faucet 4 are both relatively mature prior art in this field. Therefore, this application does not describe the structure of the water purifier 3 and the faucet 4 in detail, nor does it limit the type and model of the water purifier 3 and the faucet 4.

[0073] Considering that water pressure in the water supply pipeline may fluctuate due to various factors (such as peak water supply periods, pipeline maintenance, etc.), a pressure reducing valve is usually installed before the inlet of the water purifier 3. This not only stabilizes the water pressure in the water supply pipeline but also pre-reduces the water pressure entering the water purifier 3, preventing physical damage to the water purifier due to excessive water pressure. To simultaneously distribute purified water to both the tankless water dispenser 2 and the faucet 4, improving water utilization efficiency, a diversion valve is usually installed at the outlet of the water purifier 3. Both the inlet of the tankless water dispenser 2 and the inlet of the faucet 4 are connected to the diversion valve. When users need to obtain drinking water at a suitable temperature, such as ice water at 5℃~15℃ in hot summer, warm water at 40℃~50℃ for making formula, or hot water at 90℃~99℃ for brewing tea, users can turn on the tankless water dispenser 2 to obtain the water. When users need to use domestic water to rinse tableware, vegetables and fruits, or clothes, they can turn on tap 4 to use it.

[0074] In water purification systems, pressure reducing valves and diverter valves are configured independently. This not only occupies more space, leading to a cluttered piping layout and increased installation difficulty, but also requires separate testing and repair of the pressure reducing valve and diverter valve in case of malfunction. Replacing the pressure reducing valve and / or diverter valve within a limited space significantly increases the complexity of operation and maintenance costs.

[0075] Based on this, please refer to Figure 1 The water purification system also includes a distributor 1, a tankless water dispenser 2, a water purifier 3, and a faucet 4. The water purifier 3 has a raw water inlet 31 and a purified water outlet 32; the tankless water dispenser 2 has an inlet 211; and the faucet 4 has a purified water inlet 41. The distributor 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 purified water outlet 32, the inlet 211, and the purified 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.

[0076] Specifically, please refer to Figures 3 to 7As shown, the diverter 1 includes a valve housing 11, which includes an upper valve body shell 116 and a lower valve body shell 117 that are connected to each other. The connection here should be understood as a detachable connection, such as a bolt connection or a snap-fit ​​connection, so as to facilitate the production of the upper valve body shell 116 and the lower valve body shell 117, and also to effectively improve assembly efficiency and reduce assembly difficulty. In this embodiment, the upper valve body 116 and the lower valve body 117 form 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 116 is a one-piece molded component, and / or the lower valve body 117 is a one-piece molded component. Therefore, the valve body 11 assembled with the upper valve body 116 and the lower valve body 117 is more stable and has higher structural strength. Thus, when subjected to high-pressure fluid, the pressure can be evenly distributed in all parts of the valve body 11, effectively preventing the valve body 11 from rupturing. When subjected to external impacts, it can better resist deformation. Compared to a combination of independent pressure reducing valves and diverter valves, this type of diverter 1 is less likely to loosen or detach, reducing the risk of leakage and improving its sealing performance. This ensures more stable sealing of the water purification system during long-term use and simplifies the number of piping components (such as valves and conduits) and pipe connections, thereby reducing the difficulty of installation and subsequent maintenance. Furthermore, the one-piece molding technology allows for the manufacture of the valve body through precise molds or processing techniques, enabling better control over the dimensional and shape accuracy of the valve shell 11.

[0077] In this embodiment, please refer to the following for details. Figures 2 to 5As shown, the 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 inlet chamber 1147 of the valve body 11. The raw water outlet 1142 is used to connect to the raw water inlet 31 of the water purifier 3 to deliver the pressure-stabilized water that has flowed through the inlet chamber 1147 and undergone pressure stabilization treatment to the water purifier 3. The pure water inlet 1143 is used to connect to the pure water outlet 32 ​​of the water purifier 3 to introduce pure water purified by the water purifier 3. The first water supply port 1144 is used to connect to the tankless water dispenser 2 to deliver pure water to the tankless water dispenser 2. The second water supply port 1145 is used to connect to the faucet 4 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.

[0078] Furthermore, such as Figure 4 and Figure 5 As shown, the diverter 1 includes a pressure regulating component 16 and a diverting component 17. The pressure regulating component 16 is disposed in the inlet chamber 1147, and the diverting component 17 is disposed in the outlet chamber 1148. Thus, tap water supplied by the water supply pipeline flows into the 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 peak and off-peak water usage, maintenance and adjustments to the water supply system, etc.), for example, the water pressure is lower during peak water usage periods and relatively higher during off-peak periods such as at night. At this time, the pressure regulating component 16 can reduce / stabilize the pressure of the tap water flowing into the inlet chamber 1147, and then output it to the water purifier 3 through the raw water outlet 1142 for filtration and purification. This stabilizes the tap water pressure within a suitable range, avoiding the risk of overpressure damage or leakage to the filter element, water purification pipes, and other precision components inside the water purifier 3 due to high water pressure, thus improving the service life of the water purifier 3. In addition, the tap water flows through the filter element of the water purifier at a relatively stable flow rate, allowing the filter element to fully absorb organic matter, residual chlorine, and other impurities in the tap water, ensuring that the water purifier always maintains the best filtration effect.

[0079] Understandably, such as Figure 5As shown, the water purifier 3 performs deep filtration and purification on the pressure-stabilized water to produce pure water, which then flows through the pure water inlet 1143 of the distributor 1 and into the outlet chamber 1148. Through the cooperation between the outlet chamber 1148 and the distributor component 17, the pure water can be distributed according to actual needs, flowing from the first water supply port 1144 to the tankless water dispenser 2, and from the second water supply port 1145 to the faucet 4. During the pure water distribution, excess pure water in the outlet chamber 1148 can flow back to the return chamber 1146 under the adjustment of the distributor component 17, forming excess water. The return chamber 1146 can combine the pressure-stabilized water after it has flowed through the pressure regulating component 16 with the excess water returned by the distributor component 17, and output it to the water purifier 3 from the raw water outlet 1142.

[0080] Next, the specific structure of the voltage regulating component 16 will be described in detail with reference to the accompanying drawings.

[0081] Please refer to the specific details. Figure 4 , Figure 5 and Figure 6 As shown, the pressure regulating assembly 16 divides the water inlet chamber 1147 into an air chamber 1153 and a liquid chamber 1611. Specifically, the space enclosed by the valve body upper shell 116 and the pressure regulating assembly 16 forms the air chamber 1153. The pressure regulating assembly 16 is provided with a water injection guide hole 1612 and a pressure regulating outlet 1613, both of which are connected to the liquid chamber 1611.

[0082] Furthermore, please refer to the specific details. Figure 4 , Figure 5 and Figure 6As shown, the inner wall of the air cavity 1153 extends into the air cavity 1153 and is provided with a water injection conduit 1154 that connects to the raw water inlet 1141. The water injection conduit 1154 is inserted into the water injection guide hole 1612 of the pressure regulating component 16. Specifically, the interior of the water injection conduit 1154 is provided with a water injection channel 1155 that connects to the raw water inlet 1141. The water injection conduit 1154 connects to the liquid cavity 1611 through the water injection channel 1155, and the port of the water injection channel 1155 that connects to the liquid cavity 1611 is a water inlet. A pressure-reducing chamber outlet 1151 is provided on the valve housing 11, allowing the liquid chamber 1611 to connect to the return chamber 1146 through the pressure-reducing chamber outlet 1151. Therefore, the water pressure on the side of the liquid chamber 1611 near the pressure-regulating outlet 1613 is equal to the water pressure in the return chamber 1146. In other words, the outlet pressure on the side of the pressure-regulating assembly 16 near the pressure-regulating outlet 1613 is equivalent to the pressure of the stabilizing water supplied to the water purifier. The water pressure on the side of the liquid chamber 1611 near the water inlet guide hole 1612 is equal to the water pressure in the water supply pipe. In other words, the inlet pressure on the side of the pressure-regulating assembly 16 near the water inlet guide hole 1612 is the same as the water pressure in the water supply pipe. Since the pressure-regulating assembly 16 includes a pressure-regulating actuator located inside the liquid chamber 1611. Thus, when a pressure difference is formed between the pressure regulating outlet 1613 and the water injection guide hole 1612, the pressure regulating component 16 can generate a relative displacement along the central axis of the water injection guide section 1154 to change the throttling distance between the water inlet and the pressure regulating actuator.

[0083] Understandable, such as Figure 6 As shown, the entire process of tap water flowing into the liquid chamber 1611 is as follows: After tap water flows into the water injection channel 1155 from the raw water inlet 1141, it will flow sequentially through the water inlet port, the water injection guide hole 1612, the pressure regulating outlet 1613, the pressure reducing chamber outlet 1151, and then flow into the return chamber 1146. When the outlet pressure of the pressure regulating component 16 increases (e.g., when the water purifier 3 is turned off), the pressure on the side of the pressure regulating outlet 1613 will drive the pressure regulating component 16 to displace along the central axis of the water injection conduit 1154 towards the side closer to the water inlet port. Then, the pressure regulating actuator of the pressure regulating component 16 moves towards the water inlet port, reducing the throttling distance between the water inlet port and the pressure regulating actuator. In other words, the flow area between the water inlet port and the pressure regulating actuator is reduced until the force balance is reached. When the outlet pressure drops (e.g., when the water purifier is turned on), the pressure on one side of the water inlet guide hole 1612 will drive the pressure regulating component 16 to move along the central axis of the water inlet conduit 1154 and toward the side away from the water inlet port. The pressure regulating actuator of the pressure regulating component 16 moves away from the water inlet port, which increases the throttling distance between the water inlet port and the pressure regulating actuator until the pressure regulating actuator is back in a state of force balance.

[0084] Therefore, as the outlet pressure changes, the pressure regulating component 16 automatically shifts to alter the throttling distance between the water inlet port and the pressure regulating actuator, achieving pressure stabilization and ensuring that the pressure supplied to the water purifier remains essentially constant. The structure is simple and compact, facilitating disassembly and maintenance by subsequent personnel. Furthermore, because the water injection conduit 1154 is inserted into the water injection guide hole 1612 of the pressure regulating component 16, it not only makes the pressure regulating component 16 more stable during displacement but also ensures that the pressure regulating actuator moves precisely towards or away from the water inlet port, thereby accurately adjusting the throttling distance between the water inlet port and the pressure regulating actuator to achieve precise pressure control. During the assembly of the pressure regulating component 16 to the valve housing 11, the water injection conduit 1154 also positions the pressure regulating component 16, improving assembly efficiency and positioning accuracy.

[0085] The unexpected effect is that, for details please refer to... Figure 4 and Figure 6 As shown, tap water flowing in from the raw water inlet 1141 is guided into the liquid chamber 1611 by the water injection channel 1155, but does not fill the entire inlet chamber 1147. This not only makes the pressure regulation response more timely and accurate, but also further reduces the probability of tap water leaking out from the assembly position between the pressure regulating component 16 and the valve housing 11, thereby improving the structural stability and reliability of the diverter 1.

[0086] Please refer to the specific details. Figure 4 As shown, the pressure regulating assembly 16 includes a valve core assembly 162 and a resilient pressure regulating elastic element 163. The pressure regulating elastic element 163 is made of a material capable of elastic deformation (e.g., silicone, rubber). The water inlet 1612 and the pressure regulating outlet 1613 are both located on the valve core assembly 162. The valve core assembly 162 and the pressure regulating elastic element 163 are detachably connected, facilitating their assembly and disassembly. If the pressure regulating elastic element 163 becomes damaged or loses its elasticity after long-term use, it can be replaced individually, reducing the maintenance cost of the pressure regulating assembly 16. Figure 5 As shown, the pressure regulating elastic element 163 is connected between the upper shell 116 and the lower shell 117 of the valve body. Furthermore, when a pressure difference is formed between the pressure regulating outlet 1613 and the water injection guide hole 1612, the pressure regulating elastic element 163 can deform, and the valve core assembly 162 slides relative to the water injection guide section 1154 along its extension direction.

[0087] Understandably, when the outlet pressure on the pressure regulating outlet 1613 side of the valve core assembly 162 increases, the pressure regulating elastic element 163 undergoes elastic deformation towards the side closer to the water inlet port under the action of the outlet pressure. At the same time, it also moves along the central axis of the water injection conduit 1154 towards the side closer to the water inlet port in coordination with the valve core assembly 162. When the inlet pressure on the water injection guide hole 1612 side of the valve core assembly 162 decreases, the pressure regulating elastic element 163 resets towards the side away from the water inlet port under the action of the outlet pressure and the deformation recovery of the pressure regulating elastic element 163. At the same time, it also moves along the central axis of the water injection conduit 1154 towards the side away from the water inlet port in coordination with the valve core assembly 162.

[0088] As a preferred embodiment, please refer to the following for details. Figure 6 As shown, the valve core assembly 162 includes a valve core limiting sleeve 1621 and a valve core base 1622. The valve core limiting sleeve 1621 has a first guide hole 16121, and the valve core base 1622 has a second guide hole 16122. The first guide hole 16121 and the second guide hole 16122 constitute a water injection guide hole 1612. The central axis of the first guide hole 16121 and the central axis of the second guide hole 16122 are collinear, ensuring that the water injection conduit 1154 can sequentially pass through the first guide hole 16121 and the second guide hole 16122. A pressure regulating outlet 1613 is located on the valve core base 1622. Further, as... Figure 13 and Figure 14 As shown, the valve core limiting sleeve 1621 is sleeved on the outside of the valve core base 1622, and part of the pressure regulating elastic element 163 is sandwiched between the valve core limiting sleeve 1621 and the valve core base 1622. Preferably, the valve core base 1622 is provided with an external thread section 1625, and the valve core limiting sleeve 1621 is provided with an internal thread section 1626 that is threadedly connected to the external thread section 1625. Thus, the valve core limiting sleeve 1621 and the valve core base 1622 are screwed and fixed. This not only achieves the purpose of detachable connection between the valve core assembly 162 and the pressure regulating elastic element 163, but also makes assembly more convenient and efficient.

[0089] Specifically, such as Figure 6 As shown, the inner diameter of the port of the valve core limiting sleeve 1621 near the pressure regulating elastic element 163 is larger than the diameter of the valve core base 1622. Therefore, a clamping space is formed between the end of the valve core limiting sleeve 1621 near the pressure regulating elastic element 163 and the outer wall of the valve core base 1622. Further details can be found in the attached diagram. Figure 13 , Figure 14 and Figure 15As shown, the aforementioned pressure regulating elastic element 163 includes an elastic element body 1631 and a clamping protrusion 1632 extending from the elastic element body 1631 toward the clamping space. Both the elastic element body 1631 and the clamping protrusion 1632 extend circumferentially along the valve core base 1622. The end of the elastic element body 1631 near the valve core base 1622 and the clamping protrusion 1632 are formed together to form an elastic sleeve hole 164. The valve core base 1622 is inserted into the elastic sleeve hole 164 of the pressure regulating elastic element 163, and the clamping protrusion 1632 is clamped between the valve core limiting sleeve 1621 and the valve core base 1622. With this configuration, the valve core limiting sleeve 1621 and the valve core base 1622 cooperate to clamp the pressure regulating elastic element 163, making the connection between the pressure regulating elastic element 163 and the valve core assembly 162 more stable. This ensures that the pressure regulating elastic element 163 will not detach from the valve core assembly 162 during the elastic deformation of the pressure regulating elastic element 163 and the movement of the valve core assembly 162, thereby improving the stability of the pressure regulating assembly 16 during operation.

[0090] Further details are available according to... Figure 15 As shown, a second fastening protrusion 16332 is provided on the clamping protrusion 1632. The second fastening protrusion 16332 is integrally formed with the clamping protrusion 1632. The second fastening protrusion 16332 is clamped between the clamping protrusion 1632 and the valve core limiting sleeve 1621, thereby increasing the frictional resistance between the clamping protrusion 1632 and the valve core limiting sleeve 1621, effectively preventing the clamping protrusion 1632 from detaching from the clamping space. Of course, the second fastening protrusion 16332 can also be provided on the valve core limiting sleeve 1621. The valve core limiting sleeve 1621 is integrally formed with the second fastening protrusion 16332, which can also increase the frictional resistance between the clamping protrusion 1632 and the valve core limiting sleeve 1621.

[0091] Further details are available according to... Figure 15 As shown, the clamping protrusion 1632 is also provided with a third fastening protrusion 16333, which is integrally formed with the clamping protrusion 1632. The third fastening protrusion 16333 is clamped between the clamping protrusion 1632 and the valve core base 1622, thereby increasing the frictional resistance between the clamping protrusion 1632 and the valve core base 1622, and further preventing the clamping protrusion 1632 from detaching from the clamping space. Of course, the third fastening protrusion 16333 can also be provided on the valve core base 1622, and the third fastening protrusion 16333 is integrally formed with the valve core base 1622, which can also increase the frictional resistance between the clamping protrusion 1632 and the valve core base 1622.

[0092] It should be noted that the second fastening protrusion 16332 can be combined with the third fastening protrusion 16333, which can not only better prevent the clamping protrusion 1632 from detaching from the clamping space, but also make the clamping protrusion 1632 more compactly assembled in the clamping space.

[0093] In addition, please refer to the specific details. Figure 6 As shown, the pressure regulating assembly 16 also includes a valve core sealing ring 165. The valve core limiting sleeve 1621 and the valve core base 1622 cooperate to form a valve core sealing cavity. The valve core sealing ring 165 is sleeved on the water injection conduit 1154 and embedded inside the valve core sealing cavity to better prevent tap water from seeping out from between the water injection guide hole 1612 and the water injection conduit 1154 into the air cavity 1153.

[0094] In this embodiment, to ensure that the pressure regulating elastic element 163 can be connected more quickly and securely between the upper valve body 116 and the lower valve body 117, the inventors have provided a preferred method, which can be found in conjunction with [the following text is missing from the original] Figures 2 to 6 As shown, the aforementioned elastic element body 1631 is snapped between the upper valve body shell 116 and the lower valve body shell 117. Specifically, please refer to... Figure 15 As shown, the lower valve body 117 is provided with a housing groove, which extends circumferentially along the lower valve body 117. The pressure regulating elastic element 163 extends into the housing groove to form a sealing fastening part 1635, which extends along the length of the housing groove and is inserted into the housing groove. This arrangement not only ensures that the pressure regulating elastic element 163 is more compactly and firmly fastened to the valve body 11, facilitating the assembly of the pressure regulating component 16, but also ensures that the pressure regulating component 16 is more securely installed on the valve body 11. Simultaneously, it ensures the sealing of the connection between the pressure regulating elastic element 163 and the valve body 11, preventing water from seeping out of the valve body 11 and avoiding water infiltration into the air cavity 1153, which could lead to rust and failure of the components in the air cavity 1153. It should be noted that the housing slot can also be provided on the upper housing 116 of the valve body, or both the upper housing 116 and the lower housing 117 of the valve body can be provided with housing slots, which can be set and adjusted according to the structural design and design requirements.

[0095] Further details are available according to... Figure 15As shown, a first fastening protrusion 16331 is provided on the sealing fastening part 1635. The first fastening protrusion 16331 is integrally formed with the sealing fastening part 1635. The first fastening protrusion 16331 is sandwiched between the sealing fastening part 1635 and the housing groove, thereby increasing the frictional resistance between the sealing fastening part 1635 and the housing groove, making the sealing fastening part 1635 more securely inserted into the housing groove, and better preventing the sealing fastening part 1635 from detaching from the housing groove. Of course, the first fastening protrusion 16331 can also be provided on the groove wall of the housing groove, which can also increase the frictional resistance between the sealing fastening part 1635 and the housing groove.

[0096] As a preferred embodiment of this invention, please refer to [link / reference]. Figure 15 As shown, the elastic element body 1631 is provided with a deformation adjustment groove 1634, which has a U-shaped structure, and the opening of the deformation adjustment groove 1634 preferably faces the air cavity 1153. Figure 6 As shown, the deformation adjustment groove 1634 is formed by bending the elastic element body 1631 at the position between the valve core base 1622 and the valve housing 11, and the deformation adjustment groove 1634 extends circumferentially along the valve core base 1622. This not only provides sufficient space for the elastic element body 1631 during elastic deformation, but also provides a larger elastic deformation range within a limited space, increasing the elastic capacity of the pressure regulating elastic element 163.

[0097] As a preferred embodiment, please refer to the following for details. Figure 13 As shown, the valve core base 1622 includes a valve disc plug 1623, which serves as the pressure regulating actuator of the pressure regulating assembly 16. Figure 14 As shown, a valve disc support beam 1624 extends from the valve disc plug 1623 toward the wall of the liquid chamber 1611. The valve disc support beam 1624 extends to the body of the valve core base 1622 and is fixedly connected to the body of the valve core base 1622. To ensure good structural strength of the valve core base 1622 and to facilitate its production, the valve disc plug 1623, the valve disc support beam 1624, and the body of the valve core base 1622 are integrally formed. The valve disc support beam 1624 can be selected as one beam, extending circumferentially along the valve disc plug 1623. Multiple water flow holes are evenly arranged on the valve disc support beam 1624 along the circumferential direction of the valve disc plug 1623, allowing pressure-stabilized water to flow through the water flow holes. Alternatively, there are preferably multiple valve disc support beams 1624, which are evenly distributed around the valve disc plug 1623, and adjacent valve disc support beams 1624 are spaced apart to allow pressure-stabilizing water to flow through the circumference of the valve disc plug 1623.

[0098] To avoid rigid contact between the valve plug 1623 and the water inlet of the water inlet pipe 1154, and to reduce the noise of the distributor 1, please refer to the following for details. Figure 6 , Figure 13 and Figure 14 As shown, the valve disc plug 1623 includes a valve disc support 16231 and an elastic plug element 16232. The elastic plug element 16232 can be made of silicone. The valve disc support 16231 is provided with a valve disc insertion groove 16233 for embedding the elastic plug element 16232. The valve disc support 16231 is fixedly connected to the body of the valve core base 1622 through the valve disc support beam 1624.

[0099] In this embodiment, please refer to the following for details. Figures 4 to 6 As shown, the pressure regulating assembly 16 also includes a pressure regulating spring 166, which is located in the air cavity 1153. One end of the pressure regulating spring 166 abuts against the inner wall of the air cavity 1153, and the other end of the pressure regulating spring 166 abuts against the valve core assembly 162. When a pressure difference is formed between the pressure regulating outlet 1613 and the water injection guide hole 1612, both the pressure regulating elastic element 163 and the pressure regulating spring 166 will deform.

[0100] On the one hand, during pressure regulation, the pressure regulating spring 166 can assist the pressure regulating elastic element 163 in returning to its initial or equilibrium position after pressure changes. That is, the pressure regulating spring 166 can use its own elastic force to push the pressure regulating elastic element 163 back to a certain position, causing the valve core assembly 162 to move accordingly and return to a state close to its original state, thereby ensuring the stability of the outlet pressure. Moreover, the elastic coefficient of the pressure regulating spring 166 is relatively stable, which helps to more accurately control the deformation of the pressure regulating elastic element 163, thereby precisely controlling the outlet pressure. On the other hand, the pressure regulating spring 166 can, to a certain extent, share the pressure borne by the pressure regulating elastic element 163, thus avoiding the problem that the pressure regulating elastic element 163 might suffer excessive deformation, fatigue failure, or even damage if it bears the pressure alone when the inlet pressure is too high or when there are frequent starts and stops.

[0101] Furthermore, the combination of the pressure regulating spring 166 and the pressure regulating elastic element 163 allows the valve core assembly 162 to respond more quickly to pressure changes. When the pressure changes, the elastic force of the pressure regulating spring 166 and the deformation force of the pressure regulating elastic element 163 work together to accelerate the movement of the valve core assembly 162, that is, to quickly adjust the throttling distance between the water inlet and the pressure regulating actuator, thereby improving the pressure regulating efficiency of the diverter 1.

[0102] Furthermore, please refer to the specific details. Figures 4 to 6As shown, a pressure regulating limiting platform 1194 is provided on the inner wall of the air cavity 1153 along the extension direction of the water injection conduit 1154. The extension length of the pressure regulating limiting platform 1194 should be less than the extension length of the water injection conduit 1154. The end of the pressure regulating spring 166 is sleeved on the outside of the pressure regulating limiting platform 1194 to achieve the purpose of limiting the pressure regulating spring 166 and improving the positioning accuracy and assembly efficiency of the pressure regulating spring 166 during the assembly process.

[0103] Preferably, please refer to the following for details. Figures 4 to 6 As shown, the valve core assembly 162 can abut against the pressure regulating limit platform 1194 along the central axis of the water injection conduit 1154, thereby sealing and closing the water inlet port at the pressure regulating actuator end. That is, as the valve core assembly 162 moves along the central axis of the water injection conduit 1154 toward the side closer to the water inlet port, when the valve core limiting sleeve 1621 of the valve core assembly 162 abuts against the pressure regulating limit platform 1194, the plug elastic element 16232 of the valve core assembly 162 will also abut against the water inlet port of the water injection conduit 1154, thereby increasing the bearing area and bearing capacity of the diverter 1.

[0104] Further details are available according to... Figure 4 As shown, a breather hole 118 is also provided on the valve housing 11. The air chamber 1153 is connected to the outside of the valve housing 11 through the breather hole 118, allowing the pressure regulating assembly 16 to generate relative displacement along the central axis of the water injection conduit 1154. Understandably, when the pressure regulating elastic element 163 and the pressure regulating spring 166 deform, the internal pressure of the air chamber 1153 will change. At this time, connecting the air chamber 1153 to atmospheric pressure via the breather hole 118 helps maintain stable pressure in the air chamber 1153 where the pressure regulating spring 166 is located. This avoids the risk of excessive deformation and breakage due to the pressure difference on both sides of the pressure regulating elastic element 163 exceeding its bearing capacity, thereby improving the service life of the pressure regulating assembly 16 and the diverter 1. In addition, the pressure inside the air cavity 1153 is kept in communication with the external environment pressure through the breather hole 118. During the process of reducing / regulating the pressure of tap water, it can effectively prevent the pressure from dropping below the saturated vapor pressure of tap water and causing cavitation, thereby avoiding the vibration and noise problems caused by the presence of air bubbles in the distributor 1.

[0105] Preferably, please refer to the following: Figure 4As shown, the breather hole 118 is located on the upper valve body shell 116 of the valve housing 11, and the central axis of the breather hole 118 is parallel to the central axis of the water injection conduit 1154. From a stability perspective, this consistent orientation helps maintain the balance of the air chamber 1153. During operation, when there are slight pressure fluctuations, the pressure regulating spring 166 extends and retracts according to the pressure change. The position of the breather hole 118 allows gas to enter and exit promptly, coordinating with the actions of the pressure regulating spring 166 and the pressure regulating elastic element 163 to quickly adjust the internal pressure. Regarding the accuracy of pressure regulation, when the breather hole 118 and the pressure regulating spring 166 extend and retract in the same direction, the path of gas entering and exiting the breather hole 118 during pressure changes is more matched and coordinated with the path of internal space changes caused by the extension and retraction of the pressure regulating spring 166. This allows for more precise control of the pressure reduction.

[0106] Further details are available according to... Figure 4 As shown, the breather hole 118 is located on the side of the upper shell 116 of the valve body near the edge, and extends along the extension direction of the water injection conduit 1154 to the side of the upper shell 116 of the valve body near the pressure regulating component 16. This effectively ensures that the inner wall of the breather hole 118 is smoother and flatter, making the flow state of gas through the breather hole 118 more stable, effectively avoiding the unstable phenomenon of local turbulence in the gas, thereby ensuring that the air chamber 1153 can more accurately sense pressure changes and adjust the pressure more precisely, improving the accuracy of pressure regulation. Of course, the smooth inner wall also makes it less likely for impurities to accumulate. In some working environments, the fluid may carry tiny particulate impurities, which are easily accumulated at protrusions and may cause the breather hole 118 to become blocked over time. The smooth inner wall makes it difficult for impurities to adhere and accumulate, effectively ensuring the unobstructed flow of the breather hole 118, ensuring the normal breathing function of the air chamber 1153, and thus ensuring the stable operation of the entire distributor 1.

[0107] As a preferred embodiment, please refer to the following for details. Figure 7 and Figure 8As shown, a limiting support post 1191 is provided on the lower valve body shell 117 of the valve housing 11. The limiting support post 1191 is preferably located directly below the valve disc plug 1623, and it protrudes towards the liquid chamber 1611. The pressure regulating actuator of the pressure regulating assembly 16 can abut against the limiting support post 1191, allowing the diverter 1 to limit the pressure regulating actuator of the valve core assembly 162 when it is not in use or when the outlet pressure drops. In other words, the limiting support post 1191 can support the valve core assembly 162. At this time, the throttling distance between the pressure regulating actuator and the water inlet of the water inlet channel 1155 is at its maximum. Furthermore, an anti-sticking protrusion 1192 is provided at the end of the limiting support post 1191 near the pressure regulating actuator, creating a gap between the limiting support post 1191 and the pressure regulating actuator. This is equivalent to reducing the contact area between the limit support column 1191 and the pressure regulating actuator. It can also be understood that the pressure regulating actuator does not directly contact the end of the limit support column 1191. Therefore, when dirt accumulates at the end of the limit support column 1191, the pressure regulating actuator will not stick to the limit support column 1191, effectively preventing the problem of pressure regulating failure of the shunt 1.

[0108] Furthermore, please refer to the specific details. Figure 7 and Figure 8 As shown, the anti-stick protrusions 1192 are distributed at the edge of the end of the limiting support column 1191 and extend along the circumference of the limiting support column 1191. The anti-stick protrusions 1192 are preferably formed into an arc shape extending along the circumference of the limiting support column 1191. Then, the tap water flowing through the limiting support column 1191 can clean the end of the limiting support column 1191 by itself, reducing the probability of dirt accumulation at the end of the limiting support column 1191.

[0109] It should be noted that the anti-sticking protrusion 1192 can also be set on the pressure regulating actuator end, that is, the anti-sticking protrusion 1192 is set on the valve disc support 16231 of the valve disc plug 1623.

[0110] Preferably, the end of the limiting support column 1191 may also be provided with a groove 1193, and the anti-sticking protrusion 1192 is located on the side of the groove 1193. This arrangement effectively increases the gap distance between the limiting support column 1191 and the pressure regulating actuator, thereby further preventing the pressure regulating actuator from sticking to the limiting support column 1191 and improving the stability of the pressure regulation of the diverter 1.

[0111] Furthermore, such as Figure 16As shown, at least one through hole 16234 is provided on the side wall of the valve disc support 16231 near the limiting support column 1191. This not only facilitates the insertion of the plug elastic element 16232 into the valve disc insertion groove 16233 of the valve disc support 16231 and the pushing of the plug elastic element 16232 out of the valve disc insertion groove 16233 of the valve disc support 16231, but also further reduces the contact area of ​​the pressure regulating actuator.

[0112] In the above, the water outlet chamber 1148, together with the diversion component 17, can distribute the purified water after purification by the water purifier 3. The excess purified water inside the water outlet chamber 1148 can flow back to the return chamber 1146 under the adjustment of the diversion component 17, forming excess water. This effectively prevents the water pressure from fluctuating too much during the sudden start-up of the tankless water dispenser 2 and / or the faucet 4, which would cause the water purifier 3 to start and stop frequently.

[0113] Next, the specific structure of the above-mentioned shunt component 17 will be described in detail with reference to the accompanying drawings.

[0114] Please refer to the specific details. Figure 4 As shown, the diverter 1 also includes a diverter assembly 17, which has a flow-through hole for guiding pure water flowing in from the pure water inlet 1143 through the diverter assembly 17 and into the outlet chamber 1148. Further, the valve housing 11 has a return flow guide portion 1171, which has a guide channel 1172 communicating with the return chamber 1146. The return flow guide portion 1171 extends towards the interior of the outlet chamber 1148 and is preferably connected to the lower shell 117 of the valve body. The diverter assembly 17 is installed in the outlet chamber 1148 of the valve housing 11, and the diverter assembly 17 can abut against the return flow guide portion 1171. Based on 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 component 17 can generate a relative displacement towards the first water supply port 1144, causing the diversion component 17 to separate from the return guide section 1171. Then, excess pure water can flow from the guide channel 1172 into the return chamber 1146, forming the aforementioned excess water.

[0115] Therefore, please refer to the specific details. Figure 7 and Figure 8 As shown, when the faucet 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 adheres to 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.

[0116] 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. 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 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 when the tankless water dispenser is used alone, so that the purified water can meet the water needs of the tankless water dispenser 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.

[0117] 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. 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.

[0118] 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. With a backflow mechanism, such water pressure changes can be buffered to a certain extent, reducing the pressure of frequent start-stop cycles. When water is used simultaneously, the diversion component 17 maintains a relatively stable water flow distribution. Without the diversion component 17, when the faucet and the tankless water dispenser are working simultaneously, a sudden change in water usage on one side (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 its operating state. The diversion component 17 maintains 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.

[0119] In some embodiments, please refer to the specific details. Figure 4 As shown, the above-mentioned diversion assembly 17 includes a diversion balance membrane 172 and a balance spring 171. The diversion balance membrane 172 is provided with a diaphragm through hole 1724. The flow passage includes the diaphragm through hole 1724. Since the diversion balance membrane 172 is made of elastic material (such as silicone, rubber, etc.), the flow passage can expand and contract under its own rebound force. The balance spring 171 is disposed between the diversion balance membrane 172 and the inner wall of the outlet chamber 1148. The edge of the diversion balance membrane 172 is sandwiched between the upper shell 116 and the lower shell 117 of the valve body. Thus, when the water consumption of the tankless water purifier 2 is high, the pressure difference between the side of the diversion balancing membrane 172 near the first water inlet 1144 and the side of the diversion component 17 away from the first water inlet 1144 is significant. The flow orifice enlarges due to the pressure difference, increasing the amount of purified water flowing through it. When the water consumption of the tankless water purifier 2 decreases, the flow orifice contracts, reducing the amount of purified water flowing through it. This automatically maintains the pressure difference across the diversion balancing membrane 172, delaying its reset. At this point, no purified water flows through the first water inlet 1144, and the diversion balancing membrane 172 resets under the action of the deformation recovery of the balance spring 171. This reduces the probability of frequent start-stop cycles for the water purifier 3 under low flow conditions.

[0120] In this embodiment, please refer to the specific details. Figure 17As shown, the diversion assembly 17 also includes a diaphragm top cover 173 and a diaphragm base 174. The diaphragm top cover 173 is provided with a top cover through hole 1731, and the diaphragm base 174 is provided with a base through hole 1741. The diversion balance membrane 172 is sandwiched between the diaphragm top cover 173 and the diaphragm base 174. The diaphragm top cover 173 is preferably snapped into the diaphragm base 174. The top cover through hole 1731 and the base through hole 1741 are both connected to the diaphragm through hole 1724. At this time, the top cover through hole 1731, the base through hole 1741, and the diaphragm through hole 1724 form a flow passage. One end of the balance spring 171 abuts against the inner wall of the water outlet cavity 1148, and the other end of the balance spring 171 abuts against the diaphragm top cover 173.

[0121] As a preferred embodiment, please refer to the following for details. Figure 17 As shown, the diversion balancing membrane 172 has a flexible check valve 1721 with a flow regulating port 1722. The flexible check valve 1721 protrudes towards the membrane top cover 173 and passes through the membrane top cover 173. Based on the pressure difference between the membrane top cover 173 side and the membrane base 174 side, the flexible check valve 1721 can control the opening and closing size of the flow regulating port 1722 to regulate the increase or decrease of pure water flowing into and out of the water chamber. By utilizing the larger deformation of the flexible check valve 1721 compared to the flow passage, when the water consumption of the tankless water dispenser is large, the pressure difference between the side of the diversion balancing membrane 172 near the first water supply port 1144 and the pressure on the side of the diversion assembly 17 away from the first water supply port 1144 is large, which can supply more pure water. Similar to the principle of the elastically expandable flow hole mentioned above, when the water consumption of the tankless water purifier decreases, the flexible check valve 1721 will shrink on its own, and the amount of pure water flowing through the flexible check valve 1721 will decrease accordingly, thereby achieving the purpose of automatically maintaining the pressure difference on both sides of the diversion balance membrane 172, and also reducing the probability of the water purifier starting and stopping frequently.

[0122] It should be noted that either the method of setting the elastically expandable flow hole or the method of setting the flexible check part 1721 can be selected to reduce the probability of frequent start-stop of the water purifier when the water flow rate is low in tankless water dispensers. Of course, the two can also be used in combination.

[0123] In the above description, excess purified water inside the outlet chamber 1148 can flow back to the return chamber 1146 under the regulation of the diversion component 17. The return chamber 1146 can combine the pressure-stabilized water after it has passed through the pressure regulating component 16 with the excess water flowing back from the diversion component 17, and output it from the raw water outlet 1142 to the water purifier 3. This allows the water source to be redistributed and utilized within the water purification system, reducing water waste. However, when the amount of excess water flowing back from the outlet chamber 1148 to the return chamber 1146 is much less than the amount of pressure-stabilized water supplied from the inlet chamber 1147 to the return chamber 1146, that is, when the pressure on the side of the return chamber 1146 near the outlet chamber 1148 is less than the pressure on the side of the return chamber 1146 near the inlet chamber 1147, this can easily cause the pressure-stabilized water entering the return chamber 1146 to flow back into the outlet chamber 1148, thereby affecting the water quality of domestic water and direct drinking water.

[0124] Based on this, a preferred embodiment is also disclosed in the embodiments of this application, please refer to the following for details. Figure 4 As shown, the diverter 1 also includes a unidirectional flow guide 13, which is disposed in the return chamber 1146 to prevent the pressure-stabilized water after pressure stabilization in the inlet chamber 1147 from flowing back to the outlet chamber 1148. It also collects excess water flowing back from the outlet chamber 1148 towards the return chamber 1146 and outputs it to the water purifier after stabilization. This not only prevents the pressure-stabilized water after pressure stabilization in the inlet chamber 1147 from flowing back to the outlet chamber 1148, thus avoiding the mixing of purified water and pressure-stabilized water in the outlet chamber 1148, but also ensures the quality and quantity of purified water supplied by the diverter 1. Simultaneously, it maintains the pressure in both the outlet chamber 1148 and the inlet chamber 1147, ensuring that the water flow in the outlet chamber 1148, inlet chamber 1147, and return chamber 1146 follows the designed direction and pressure conditions, achieving stability while simplifying the piping components and connections of the water purification system.

[0125] An unexpected benefit is that the unidirectional flow guide 13, when assembled in the return chamber 1146 of the valve housing 11, makes the assembly between the unidirectional flow guide 13 and the valve housing 11 more compact. In a space-constrained water purification system, this assembly method offers a higher degree of integration, saves space, effectively simplifies the piping layout of the system, and reduces the risk of leakage due to excessive pipe connections. Furthermore, it prevents damage to the distributor 1 and the water purification system caused by water hammer. Understandably, when the external water supply pipe pressure increases instantaneously, the inertia of the water flow will cause a water hammer effect, generating a high pressure wave. At this time, the unidirectional flow guide 13 can prevent this high-pressure wave from impacting the unidirectional flow guide 13 in the reverse direction, which helps extend the service life of the distributor 1 and reduces the maintenance costs of the distributor 1 and the water purification system.

[0126] As a preferred embodiment, please refer to the following for details. Figure 9 , Figure 10 and Figure 11 As shown, the aforementioned unidirectional flow guide 13 includes a check valve 131 and a mixing guide 132. The check valve 131 has an inlet 1311 and an outlet 1312. The check valve 131 is used to control the flow of water from the inlet 1311 to the outlet 1312. Understandably, this water source refers to excess water flowing back from the water chamber 1148 toward the return chamber 1146. The mixing guide 132 has a flow channel 1321 inside. The mixing guide 132 has an extension 133 with an injection port 1331 protruding from the side of the check body 131. The extension 133 extends along the circumferential part of the mixing guide 132 and is located at the end of the mixing guide 132. One end of the check body 131 with an output port 1312 abuts against the extension 133 to form a mixing chamber 1332. At this time, the opening formed by the mixing guide 132, the extension 133, and the check body 131 is the injection port 1331. The injection port 1331 is connected to the mixing chamber 1332, and the output port 1312 is connected to the mixing chamber 1332. The input port 1311 is connected to the water outlet chamber 1148.

[0127] Furthermore, please refer to the specific details. Figure 7 and Figure 8 As shown, the injection port 1331 of the unidirectional flow guide 13 is positioned towards the water inlet chamber 1147, that is, the injection port 1331 is aligned with the water inlet chamber 1147, and the injection port 1331 is connected to the water inlet chamber 1147. Then, the pressure-stabilized water flowing into the return chamber 1146 will flow into the mixing chamber 1332 through the injection port 1331. The inlet port 1311 of the check body 131 is connected to the outlet chamber 1148, and the flow guide channel 1321 is connected to the raw water outlet 1142 of the lower shell 117 of the valve body. Then, excess water can only flow in from the inlet port 1311 of the check body 131 and enter the mixing chamber 1332 through the outlet port 1312. At this time, the excess water mixes with the pressure-stabilized water. After the excess water mixes with the pressure-stabilized water, it is guided by the flow guide channel 1321 to the raw water outlet 1142 and delivered to the water purifier. When the pressure in the mixing chamber 1332 is too high, that is, when the pressure on the side of the return chamber 1146 near the outlet chamber 1148 is less than the pressure on the side of the return chamber 1146 near the inlet chamber 1147, the check valve 131 will close automatically under the pressure, thereby preventing the pressure-stabilized water from flowing back to the outlet chamber 1148.

[0128] It should be further explained that, in order to ensure that the extension 133 can more smoothly abut against the end face of the check body 131 where the input port 1311 is located, please refer to the following for details. Figures 7 to 12As shown, an auxiliary support portion 135 protrudes from the side of the mixing fluid 132 facing the check body 131. The auxiliary support portion 135 is preferably distributed opposite to the extension portion 133, and the length of the auxiliary support portion 135 is equal to the length of the extension portion 133. The end of the auxiliary support portion 135 away from the mixing fluid 132 abuts against the check body 131. This arrangement ensures that both the auxiliary support portion 135 and the extension portion 133 abut against the check body 131, achieving a more balanced force distribution between the mixing fluid 132 and the check body 131. It also increases the contact area between the mixing fluid 132 and the check body 131, thereby ensuring the compactness and stability of the overall structure of the unidirectional flow guide 13.

[0129] Preferably, please refer to the following for details. Figure 7 and Figure 8 As shown, a positioning protrusion 1322 is provided on the outer side wall of the extension 133. The extension direction of the positioning protrusion 1322 is consistent with the extension direction of the guide channel 1321. The positioning protrusion 1322 is located on one side of the injection port 1331. A positioning groove 1149 is provided on the valve body 11. The positioning groove 1149 is located inside the return cavity 1146 and extends along the extension direction of the return cavity 1146. When the unidirectional flow guide 13 is assembled into the return cavity 1146, the positioning protrusion 1322 is inserted into the positioning groove 1149. Through the cooperation between the positioning protrusion 1322 and the positioning groove 1149, the injection port 1331 of the unidirectional flow guide 13 can be aligned with the water inlet cavity 1147, that is, the pressure reducing chamber outlet 1151 is aligned with the injection port 1331. The injection port 1331 completely covers the pressure reducing chamber outlet 1151, so that the pressure-stabilized water can flow more smoothly through the pressure reducing chamber outlet 1151 and the injection port 1331 and enter the mixing cavity 1332, thereby avoiding the problem of unstable water pressure caused by turbulence or eddies due to obstruction of the pressure-stabilized water.

[0130] Furthermore, during the assembly of the unidirectional flow guide 13 into the return cavity 1146, it is only necessary to align the positioning protrusion 1322 of the unidirectional flow guide 13 with and slide it into the positioning groove 1149 inside the return cavity 1146. This improves the convenience and efficiency of assembling the unidirectional flow guide 13, facilitates the subsequent disassembly and maintenance of the unidirectional flow guide 13, improves the efficiency of overhauling the distributor 1, and ensures the stability of the distributor 1 during long-term use. Since the positioning protrusion 1322 is constrained by the positioning groove 1149, it effectively prevents the unidirectional flow guide 13 from deflecting or shifting in the return cavity 1146, ensuring that the injection port 1331 of the unidirectional flow guide 13 is always aligned with the pressure reducing chamber outlet 1151 of the valve housing 11, reducing the impact and vibration of the valve housing 11 on the pressure-stabilized water, thereby reducing the noise of the distributor 1 during use.

[0131] Furthermore, please refer to the specific details. Figure 10 and Figure 11As shown, the end of the mixing fluid 132 near the extension 133 is the shoulder end of the mixing fluid 132. The shoulder end is misaligned with the extension 133 to form a shoulder portion 134. Understandably, the cross-sectional dimension of the shoulder end is larger than that of the extension 133. Therefore, the shoulder portion 134 is the part where the shoulder end connects to the extension 133 and where the cross-sectional dimension changes. Figure 8 As shown, a stepped limiting part 1152 is provided on the valve housing 11. The stepped limiting part 1152 is located inside the return cavity 1146. That is, the stepped limiting part 1152 is formed by the inner wall of the channel of the return cavity 1146 protruding towards the inside of the return cavity 1146. The shoulder end of the one-way flow guide 13 abuts against the stepped limiting part 1152 of the valve housing 11. Then, the shoulder 134 of the one-way flow guide 13 can make the mixing flow guide 132 translate in the extension direction of the positioning protrusion 1322.

[0132] In this embodiment, the mixing fluid 132 of the unidirectional flow guide 13 is inserted into the interior of the return cavity 1146 under the guidance of the positioning groove 1149 until the shoulder 134 abuts against the stepped limiting part 1152 of the contact valve housing 11, thereby restricting the movement of the mixing fluid 132 in the extension direction of the return cavity 1146 and achieving the purpose of efficient positioning.

[0133] Preferably, please refer to the following for details. Figure 9 , Figure 10 and Figure 11 As shown, a flow-guiding slope 136 is provided between the inner wall of the mixing chamber 1332 and the inner wall of the guide channel 1321. The flow-guiding slope 136 extends inclinedly from the mixing chamber 1332 toward the inner wall of the guide channel 1321. This design not only avoids drastic changes in a short time due to height differences during the flow of pressurized water from the mixing chamber 1332 to the guide channel 1321, thus preventing large impact forces and local turbulence instability, but also ensures that the pressurized water is transported to the water purifier from the raw water outlet 1142 through the mixing chamber 1332 and the guide channel 1321 at a relatively stable speed and state.

[0134] As a preferred embodiment, please refer to the following for details. Figure 9 and Figure 10 As shown, the check valve 131 includes a fixed housing 1313 and a valve core 1314. The valve core 1314 is movably disposed inside the fixed housing 1313. Both the inlet 1311 and the outlet 1312 are located on the fixed housing 1313. The valve core 1314 can open and close the inlet 1311 based on the pressure difference between the inlet 1311 and the outlet 1312. It can be understood that the water pressure on the inlet 1311 side is equivalent to the pressure on the side of the return chamber 1146 near the outlet chamber 1148, and the water pressure on the outlet 1312 side is equivalent to the pressure on the side of the return chamber 1146 near the inlet chamber 1147.

[0135] When the water pressure on the inlet 1311 side is greater than the water pressure on the outlet 1312 side, the valve core 1314 opens the inlet 1311, allowing excess water flowing back from the outlet chamber 1148 towards the return chamber 1146 to enter the fixed housing 1313 through the inlet 1311, and then flow through the fixed housing 1313 before entering the mixing chamber 1332 from the outlet 1312. Conversely, when the water pressure on the inlet 1311 side is less than or equal to the water pressure on the outlet 1312 side, the valve core 1314 resets and closes the inlet 1311. This prevents the pressure-stabilized water entering the mixing chamber 1332 from flowing back through the fixed housing 1313 to the outlet chamber 1148, thus achieving unidirectional flow control of excess water.

[0136] Preferably, please refer to the following for details. Figure 11 and Figure 12 As shown, the valve core 1314 includes a movable opening / closing part 13141 and an elastic reset part 13142. The elastic reset part 13142 is preferably a spring. However, it can also be a component made of an elastic material (such as rubber or silicone). The elastic reset part 13142 is preferably sleeved on the movable opening / closing part 13141, with both ends abutting against the movable opening / closing part 13141 and the fixed housing 1313, respectively. Specifically, the movable opening / closing part 13141 is provided with a spring-embedded groove. The shape and size of the spring-embedded groove are adapted to the shape and size of the elastic reset part 13142. The end of the elastic reset part 13142 is embedded inside the spring-embedded groove to prevent displacement of the elastic reset part 13142 during deformation.

[0137] Thus, when the water pressure on the inlet 1311 side is less than or equal to the water pressure on the outlet 1312 side, the sealing head 13143 of the movable opening and closing part 13141 abuts against and seals the inlet 1311, effectively preventing the pressure-stabilized water from flowing through the inlet 1311. When the water pressure on the inlet 1311 side is greater than the water pressure on the outlet 1312 side, the sealing head 13143 of the movable opening and closing part 13141 moves away from the inlet 1311 under pressure, and simultaneously squeezes the elastic reset part 13142 to generate deformation, so that the inlet 1311 and the outlet 1312 are connected. At this time, excess water can enter the outlet chamber 1148 through the inlet 1311. Understandably, when the water pressure on the inlet 1311 side is lower than the water pressure on the outlet 1312 side again, the sealing head 13143 of the movable opening and closing part 13141 moves toward the inlet 1311 side under the deformation recovery action of the elastic reset part 13142. Then the sealing head 13143 will automatically abut against the sealing inlet 1311, preventing the pressure-stabilized water from flowing through the inlet 1311 into the outlet chamber 1148.

[0138] To ensure a proper seal between the sealing head 13143 and the inlet 1311, please refer to the following: Figure 11 and Figure 12 As shown, a first sealing groove is provided on the sealing head 13143, extending circumferentially along the sealing head 13143, and a check seal ring 13144 is embedded in the first sealing groove. Under the action of the check seal ring 13144, the sealing performance between the sealing head 13143 and the inlet 1311 can be effectively improved. At the same time, it also ensures that the sealing head 13143 of the movable opening and closing part 13141 makes flexible contact with the fixed shell 1313 during the opening and closing process, reducing the wear of the check body 131 during frequent opening and closing, thereby effectively improving the service life of the check body 131 and the unidirectional fluid guide.

[0139] Preferably, please refer to the following for details. Figure 11 and Figure 12 As shown, the aforementioned fixed housing 1313 includes a valve seat housing 13131 and a retaining inner frame 13132. The valve seat housing 13131 is sleeved on the outside of the retaining inner frame 13132. The movable opening and closing part 13141 is inserted into the retaining inner frame 13132. The end of the elastic reset part 13142 abuts against the retaining inner frame 13132. The inlet 1311 is provided on the valve seat housing 13131, and the outlet 1312 is provided on the retaining inner frame 13132. When assembling the check body 131, first, the movable opening and closing part 13141 of the valve core 1314 is placed into the valve seat housing 13131. Then, the elastic reset part 13142 of the valve core 1314 is fitted onto the movable opening and closing part 13141. Finally, the retaining inner frame 13132 is embedded inside the valve seat housing 13131, with the movable opening and closing part 13141 inserted into the retaining inner frame 13132. This completes the assembly of the check body 131. At this time, the sealing head 13143 of the movable opening and closing part 13141 abuts against the inlet 1311 sealed on the valve seat housing 13131, and the elastic reset part 13142 is in a state of compression deformation. With this configuration, the valve seat housing 13131 and the retaining inner frame 13132 can be produced separately, reducing the manufacturing difficulty of the fixed housing 1313 and thus helping to reduce the manufacturing cost of the fixed housing 1313. At the same time, it facilitates the assembly of the check body 131, improves the assembly efficiency of the check body 131, and reduces the assembly cost of the check body 131.

[0140] Specifically, please see Figure 9A retaining arm 13134 is provided on the inner frame 13132. The retaining arm 13134 is located inside the output port 1312. That is, the retaining arm 13134 extends from the inner frame 13132 toward the inner side of the output port 1312. The retaining arm 13134 is provided with a guide hole 13136 for inserting into the movable opening and closing part 13141. The shape of the guide hole 13136 can be adapted to the shape of the end of the movable opening and closing part 13141. Of course, the shape of the guide hole 13136 can also be adapted to the shape of the movable opening and closing part. The shapes of the ends of 13141 are different, but it is necessary to ensure that the side wall of the end of the movable opening and closing part 13141 abuts against the inner wall of the guide hole 13136 so that the movable opening and closing part 13141 can reciprocate along the central axis of the guide hole 13136. Thus, the guide hole 13136, together with the elastic reset part 13142, can ensure that the sealing head 13143 of the movable opening and closing part 13141 is accurately reset and abuts against the input port 1311. The end of the elastic reset part 13142 abuts against the retaining arm 13134.

[0141] It should be noted here that, for details please refer to [the relevant documentation / reference]. Figures 9 to 12 As shown, a limiting boss 13135 is provided on the support arm 13134 protruding towards the movable opening and closing part 13141. The guide hole 13136 passes through the limiting boss 13135, thereby increasing the contact area between the side wall of the end of the movable opening and closing part 13141 and the inner wall of the guide hole 13136. The end of the elastic reset part 13142 is sleeved on the limiting boss 13135. In this way, the limiting boss 13135 cooperates with the spring groove provided on the movable opening and closing part 13141, which not only ensures that the elastic reset part 13142 is stably assembled in the fixed shell 1313, but also further prevents the elastic reset part 13142 from shifting during deformation.

[0142] Further details are available according to... Figure 11 As shown, in order to reduce the weight of the fixed shell 1313 and the check body 131, and also reduce the production material of the fixed shell 1313, thereby reducing the production cost of the fixed shell 1313 and the check body 131, at least one subtraction port 13133 is provided on the side wall of the inner frame 13132. The shape, size and number of the subtraction port 13133 are not limited here. The shape, size and number of the subtraction port 13133 can be set and adjusted according to the structural design and design requirements.

[0143] It should be further noted that, in order to ensure the sealing between the valve seat outer shell 13131 of the fixed shell 1313 and the inner wall of the return cavity 1146, please refer to the following for details. Figures 7 to 12As shown, a second sealing groove is provided on the valve seat housing 13131. The second sealing groove extends along the circumference of the valve seat housing 13131. An outer sealing ring 137 is embedded in the second sealing groove. Under the action of the outer sealing ring 137, the sealing performance between the fixed shell 1313 of the check body 131 and the inner wall of the return cavity 1146 can be effectively improved.

[0144] It should also be noted that, in order to securely install and fix the aforementioned unidirectional flow guide 13 in the return cavity 1146 of the valve housing 11, please refer to the following for details. Figure 7 and Figure 8 As shown, a pipe connector 14 is installed at the raw water outlet 1142. The pipe connector 14 is used to completely constrain the unidirectional flow guide 13 in the return cavity 1146, and a conduit can also be connected through the pipe connector 14.

[0145] In addition, such as Figure 4 , Figure 7 , Figure 8 As shown, at least one fastening sealing ring 15 can be configured between the pipe connector 14 and the one-way flow guide 13. On the one hand, the end of the conduit passes through the fastening sealing ring 15, which improves the sealing performance between the conduit and the return chamber 1146, effectively preventing the water pressure stabilizer from leaking out from the connection between the raw water outlet 1142 and the pipe connector 14, and also making the conduit more securely connected to the distributor 1. On the other hand, the elasticity of the fastening sealing ring 15 not only allows the pipe connector 14 and the one-way flow guide 13 to be flexibly connected, but also allows the fastening sealing ring 15 to undergo elastic deformation under the compression of the pipe connector 14 and the one-way flow guide 13 when the pipe connector 14 is assembled to the raw water outlet 1142. This deformation allows the fastening sealing ring 15 to fill the assembly gap between the pipe connector 14 and the one-way flow guide 13, and to adaptively change its shape according to the size and shape of the assembly gap. At the same time, this elastic deformation also allows the fastening sealing ring 15 to compensate for the gap changes caused by expansion, vibration and other factors during the operation of the distributor 1, thereby maintaining the stability of the assembly gap.

[0146] Of course, pipe fitting 14 can also be other quick-connect or fast-plug connectors. Similarly, pipe fitting 14 and the aforementioned fastening sealing ring 15 are also compatible with the raw water inlet 1141, pure water inlet 1143, first water supply port 1144 and second water supply port 1145. The model and size of pipe fitting 14 can be appropriately adjusted according to the raw water inlet 1141, pure water inlet 1143, first water supply port 1144 and second water supply port 1145.

[0147] In related technologies, water dispensers have water tanks, which makes the dispensers bulky, limits installation space, and makes the water tanks prone to bacterial growth, which is detrimental to water quality safety. Based on this, this application also provides a tankless water dispenser 2, which will be described in detail below.

[0148] Please see Figures 18 to 20 The tankless water dispenser 2 includes a housing 21, a water system 22, an instant heating device 25, and a water outlet pipe 29. The housing 21 has an inlet 211 and an outlet 212. The housing 21 may include a first shell and a second shell, which can be detachably connected by snap-fit, screws, or other means. The first shell and the second shell 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 electrical 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 electrical control device 24 can accurately adjust parameters such as water flow rate and water temperature to meet different user needs.

[0149] 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.

[0150] To 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.

[0151] For further details, please refer to Figure 19 and Figure 20The 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. This can reduce electromagnetic interference and ensure the stability and reliability of the power signal of the electrical control device 24.

[0152] Please return to the reference. Figure 23 The water system 22 includes a hot water path 221 and a high-temperature return water path 223. The inlet of the high-temperature return water path 223 is connected to the outlet of the instant heating device 25, and the outlet is connected to the hot water path 221 and located upstream of the pump assembly 2212. The hot water from the instant heating device 25 can selectively flow to the high-temperature return water path 223 or the water outlet 212. Specifically, a temperature sensor can be installed downstream of the instant heating device 25 to monitor the water temperature flowing out of the instant heating device 25 in real time. If the water temperature fails to meet the user's set temperature requirement, the low-temperature hot water will be guided to the front of the pump assembly 2212 through the high-temperature return water path 223 and flow through the instant heating device 25 again for secondary heating until the water temperature reaches the user's desired value. In addition, since the high-temperature water is returned to the front of the pump assembly 2212, this high-temperature water can effectively reheat and sterilize the pump assembly 2212, thereby further improving the hygienic performance of the entire water system 22.

[0153] Please see Figure 23 In some embodiments, the high-temperature return water path 223 includes a three-way valve 2231. The inlet of the three-way valve 2231 is connected to the outlet of the instant heating device 25, the first outlet of the three-way valve 2231 is connected to the water outlet 212, and the second outlet of the three-way valve 2231 is connected to the hot water path 221 and located upstream of the pump assembly 2212. Thus, the flow direction of the hot water from the instant heating device 25 can be controlled by a single three-way valve 2231. When the water temperature meets the user's needs, it flows to the water outlet 212; when the water temperature does not meet the preset value, it flows back upstream of the pump assembly 2212 for reheating. In this example, there is only one component, resulting in a compact structure and simple installation.

[0154] Please see Figure 24In some embodiments, the high-temperature return water path 223 further includes a first solenoid valve 2232 and a second solenoid valve 2233. The first solenoid valve 2232 selectively connects the outlet of the instant heating device 25 and the inlet of the high-temperature return water path 223; the second solenoid valve 2233 selectively connects the outlet of the instant heating device 25 and the water outlet 212. In this example, the flow direction of the hot water from the instant heating device 25 is controlled by the coordinated use of the two solenoid valves.

[0155] Please see Figure 23 and Figure 24 In some implementations, the water system 22 also includes a normal temperature water path 222, which is equipped with a second inlet solenoid valve 2221. The inlet of the normal temperature water path 222 is connected to the hot water path 221 and located downstream of the first inlet solenoid valve 2211. Alternatively, the inlet of the normal temperature water path 222 is connected to the inlet 211, and the outlet of the normal temperature water path 222 is connected to the hot water path 221 and located downstream of the pump assembly 2212. The hot water path 221 provides hot water, while the normal temperature water path 222 provides normal temperature water. Because the hot water path 221 is equipped with a pump 2214, its water flow rate is relatively small, but sufficient to meet the immediate daily hot water demand. The normal temperature water path 222 cleverly bypasses the pump assembly 2212, directly controlling the flow through the second inlet solenoid valve 2221, thus increasing the water flow rate and fully meeting the needs of high-volume water usage scenarios. Furthermore, even when the instant heating device 25 is not activated to heat hot water, room 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.

[0156] To facilitate the installation of the hot water circuit 221 within the housing 21, the first inlet solenoid valve 2211 and the pump assembly 2212 are arranged side-by-side in the water circuit 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, and 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. Furthermore, the ambient temperature water circuit 222 can also be installed within the water circuit installation area 2141, and the second inlet solenoid valve 2221 can be arranged side-by-side with the first inlet solenoid valve 2211 along the length direction or along the height direction within the water circuit installation area 2141; this application does not impose any limitations on this.

[0157] 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.

[0158] Since it is a tankless design, the hot water circuit 221 requires a first inlet solenoid valve 2211 and a pump assembly 2212. The first inlet solenoid valve 2211 controls the flow of water, and the pump assembly 2212 provides 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 smaller. 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 circuit installation area 2141, and the instant heating device 25 and the outlet pipe 29 are located within 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.

[0159] It should be noted that the first and second shells of this application are horizontally enclosed and fixedly connected. After the first shell is disassembled, the equipment of the water system 22 and the instant heating device 25 are arranged side by side inside the second shell. In this way, the internal equipment can be clearly seen, facilitating maintenance or replacement. During installation and use, the second shell is hung on the wall. This eliminates the need to remove the entire tankless water dispenser 2, allowing for direct maintenance or repair of the components inside the mounting cavity 215 after disassembling the first shell. Furthermore, considering the installation environment, the back of the tankless water dispenser 2 is attached to the wall. The second shell can be a cover with an opening on the front, while the first shell forms a cover structure that closes the opening.

[0160] In some embodiments, pump assembly 2212 may include a flow control pump and a water pump. When pump assembly 2212 includes a water pump, 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 the water pump, and is located between the first inlet solenoid valve 2211 and the water pump. When the water flow in water system 22 is cut off or the water pump 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 the water pump and other components in water system 22 from damage. There are various ways in which negative pressure valve 2217 prevents the generation of negative pressure, such as air injection, pre-pressurization, etc. The specific structure and principle of the negative pressure valve 2217 have been disclosed in relevant technologies, and this application will not elaborate on them.

[0161] Of course, if pump assembly 2212 is a flow-controlled pump, a negative pressure valve 2217 may not be required. A flow-controlled pump is a pump that can maintain a constant pressure when the flow rate changes. By precisely controlling the flow rate and pressure of water, a flow-controlled pump can stabilize the fluid state within a delivery pipeline. In some cases, when the water flow in the delivery pipeline is cut off, the flow-controlled pump can adjust its output flow rate to maintain the fluid pressure within the pipeline within a stable range, thereby preventing negative pressure from occurring.

[0162] Please see Figures 19 to 20 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; or between the water pump 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.

[0163] Please see Figures 19 to 20In 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; or between the water pump 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.

[0164] Please see Figures 19 to 20 In some embodiments, the first inlet solenoid valve 2211, the negative pressure valve 2217, the water flow sensor 2215, the flow meter 2216, and the water pump are sequentially connected in the direction of water flow. The first inlet solenoid valve 2211 and the negative pressure valve 2217 are spaced apart along the height of the housing 21. The water flow sensor 2215, the flow meter 2216, and the water pump are also spaced apart along the height of the housing 21, located between the entire assembly formed by the first inlet solenoid valve 2211 and the negative pressure valve 2217, and the entire assembly formed by the instant heating device 25 and the outlet pipe 29. The water pump is located below the water flow sensor 2215 and the flow meter 2216. The components such as the first inlet solenoid valve 2211, the negative pressure valve 2217, the water flow sensor 2215, the flow meter 2216, and the water pump 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.

[0165] Please see Figure 19 and Figure 20 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 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.

[0166] Please see Figure 22 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.

[0167] Please see Figures 19 to 22 ,as well as Figure 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.

[0168] 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 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, 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.

[0169] 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.

[0170] In this application, the first inlet solenoid valve 2211, the flow control pump, 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 interference.

[0171] Please see Figure 22 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 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.

[0172] Please refer to 22. 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 the user 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 the user to more intuitively check the cleanliness of the water-holding area and the water outlet 212, thereby reminding the user to clean and maintain in a timely manner to ensure water hygiene.

[0173] Please see Figure 21In 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.

[0174] 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.

[0175] Please return to the reference. Figure 1 The fresh mineral water passage 5 connects to an external fresh mineral water source and the water system 22. In the direction of water flow, the outlet of the fresh mineral water passage 5 is located upstream of the pump assembly 2212. The outlet of the fresh mineral water passage 5 can be connected to the hot water passage 221, allowing external fresh mineral water to flow through both the fresh mineral water passage 5 and the hot water passage 221 to the instant heating device 25, which then heats this portion of the fresh mineral water. The fresh mineral water passage 5 is equipped with a third inlet solenoid valve 51, which controls the opening and closing of the fresh mineral water passage 5.

[0176] Furthermore, the water purifier 3 can be equipped with a fresh mineral water outlet, and the fresh mineral water channel 5 connects the fresh mineral water outlet and the water system 22. Currently, some water purifiers 3 on the market can simultaneously provide pure water and fresh mineral water. Thus, this application, through the fresh mineral water channel 5 and the water system 22 within the tankless water dispenser 2, allows users to drink either heated pure water or fresh mineral water, meeting different user needs.
