[0083] In order to make the objectives, technical solutions and advantages of the present application clearer, the following part will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.

[0084] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0085] In the description of the present application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0086] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0087] On the one hand, the present application proposes a drinking water purification system, which includes a water purifier, a tankless pipeline machine and a faucet. The water purifier is used to deeply filter and purify the water source provided by the water supply pipeline, so that the water quality of the water source reaches the standard that is safe for drinking or meets specific usage requirements. The tankless pipeline machine is used to instantly heat or cool the purified water source, so that users can accurately obtain drinking water and meet the different drinking water temperature requirements of users. It should be noted that the water purifier, the tankless pipeline machine and the faucet are all relatively mature existing technologies in this field, and the present application has not made significant improvements to the water purifier, the tankless pipeline machine and the faucet. Therefore, the present application does not elaborate on the structure of the water purifier, the tankless pipeline machine and the faucet, nor does it limit the types and models of the water purifier and the tankless pipeline machine.

[0088] Considering that the water pressure in the water supply pipeline may change due to various factors (such as water supply peak period, pipeline maintenance, etc.), a pressure reducing valve is usually installed before the water inlet of the water purifier, which not only stabilizes the water pressure in the water supply pipeline but also reduces the water pressure entering the water purifier in advance to avoid physical damage to the water purifier due to excessive water pressure. In order to distribute the purified water source to the tankless pipeline machine and the faucet at the same time and improve the water utilization efficiency, a diverter valve is usually installed at the rear end of the water outlet of the water purifier, and the water inlet end of the tankless pipeline machine and the water injection port of the faucet are connected to the diverter valve. When the user needs to take direct drinking water with the appropriate temperature, such as drinking ice water at 5℃~15℃ in the hot summer, or taking warm water at 40℃~50℃ to make milk powder, or taking hot water at 90℃~99℃ to make tea, the user can turn on the tankless pipeline machine for use. When the user needs to use domestic water to wash dishes, wash vegetables and fruits, or wash clothes, the user can turn on the faucet to use it.

[0089] In the drinking water purification system, the pressure reducing valve and the diverter valve are configured independently, which not only takes up more space and causes a messy pipeline layout, but also increases the difficulty of installation. Moreover, when a failure occurs, the pressure reducing valve and the diverter need to be inspected and repaired separately, and replacing the pressure reducing valve and / or the diverter 1 in a limited space will greatly increase the complexity of operation and maintenance cost.

[0090] Based on this, an embodiment of the present application provides a drinking water purification system, which also includes a diverter 1. The faucet, tankless pipeline machine, water purifier and water supply pipeline are all connected to the diverter 1, so that the water supply pipeline can introduce tap water into the diverter 1 and adjust the excessively high and unstable water pressure of the tap water in the water supply pipeline and maintain it within a preset pressure value range, and finally generate stabilized pressure water and transport it to the water purifier. The water purifier will deeply filter and purify the stabilized pressure water to generate pure water and flow to the diverter 1 again. After being distributed through the diverter 1, the pure water flowing to the faucet will be used as domestic water, and the pure water flowing to the tankless pipeline machine will be used as direct drinking water.

[0091] Specifically, please combine Figures 1 to 5As shown, the diverter 1 includes a valve housing 11, which includes a valve body upper shell 116 and a valve body lower shell 117 that are interconnected. The interconnection here should be understood as a detachable connection, such as a bolt connection, a snap connection, etc., to facilitate the production of the valve body upper shell 116 and the valve body lower shell 117, and can also effectively improve the assembly efficiency and reduce the difficulty of assembly. In this embodiment, the valve body upper shell 116 and the valve body lower shell 117 are configured with a water inlet chamber 1147, a reflux chamber 1146 and a water outlet chamber 1148. The water outlet chamber 1148 can be connected to the water inlet chamber 1147 through the reflux chamber 1146. The water inlet chamber 1147 and the water outlet chamber 1148 are preferably located on the top side of the reflux chamber 1146. The valve body upper shell 116 is an integrally formed component, and / or the valve body lower shell 117 is an integrally formed component. Then, the valve housing 11 after the valve body upper shell 116 and the valve body lower shell 117 are assembled is more stable and has a higher structural strength. In this way, when subjected to high-pressure fluid, the pressure can be evenly distributed in various parts of the valve housing 11, effectively preventing the valve housing 11 from rupturing. When subjected to external impact, it can better resist deformation. Compared with the combination of an independent pressure reducing valve and a diverter valve, such a diverter 1 is less likely to loosen or detach, reducing the risk of leakage of the diverter 1 and improving the sealing performance of the diverter 1, thereby ensuring that the sealing of the drinking water purification system is more stable during long-term use, and also simplifying the number of pipeline components (such as valves, conduits, etc.) and pipeline connections of the drinking water purification system, thereby helping to reduce the difficulty of installation and subsequent maintenance of the drinking water purification system. At the same time, the one-piece molding technology can realize the manufacture of the valve body through precise molds or processing techniques, and can also better control the dimensional accuracy and shape accuracy of the valve housing 11.

[0092] In this embodiment, please refer to Figures 1 to 4As shown, the diverter 1 is provided with a raw water inlet 1141, a pure water inlet 1143, a raw water outlet 1142, a first water supply port 1144 and a second water supply port 1145, wherein the raw water inlet 1141 is used to connect the water supply pipe to introduce tap water into the water inlet chamber 1147 of the valve housing 11, the raw water outlet 1142 is used to connect the water purifier to deliver the pressure-stabilized water that flows through the water inlet chamber 1147 and is pressure-stabilized to the water purifier, the pure water inlet 1143 is used to connect the water purifier to introduce the pure water purified by the water purifier, the first water supply port 1144 is used to connect the water tankless pipeline machine to deliver the pure water to the water tankless pipeline machine, and the second water supply port 1145 is used to connect the faucet to deliver the pure water to the faucet. The raw water inlet 1141 is connected to the water inlet chamber 1147, the raw water outlet 1142 is connected to the reflux chamber 1146, and the pure water inlet 1143, the first water supply port 1144, and the second water supply port 1145 are all connected to the water outlet chamber 1148. Preferably, the raw water outlet 1142, the pure water inlet 1143, and the second water supply port 1145 are all arranged on the valve body lower shell 117, and the raw water inlet 1141 and the first water supply port 1144 are arranged on the valve body upper shell 116.

[0093] Furthermore, if Figure 3 and Figure 4 As shown, the diverter 1 includes a pressure regulating component 16 and a diverter component 17, the pressure regulating component 16 is arranged in the water inlet chamber 1147, and the diverter component 17 is arranged in the water outlet chamber 1148. In this way, the tap water supplied by the water supply pipe flows into the water inlet chamber 1147 from the raw water inlet 1141. If the water pressure in the urban water supply network changes due to various factors (such as water consumption peaks and valleys, maintenance and adjustment of the water supply system, etc.), for example, the water pressure is low during the peak water supply stage, and the water pressure is relatively high during the water consumption valley period such as at night. At this time, the pressure regulating component 16 will be able to reduce the pressure / stabilize the tap water flowing into the water inlet chamber 1147 into stabilized water, and then output it to the water purifier through the raw water outlet 1142 for filtration and purification, stabilizing the water pressure of the tap water within a suitable range, so as to avoid the risk of overpressure damage or leakage of the water purifier caused by the high water pressure acting on the filter element, water purification pipeline and other precision components inside the water purifier, thereby improving the service life of the water purifier. In addition, tap water passes through the filter element of the water purifier at a relatively stable flow rate, allowing the filter element to fully absorb impurities such as organic matter and residual chlorine in the tap water, ensuring that the water purifier always maintains the best filtering effect.

[0094] Understandably, if Figure 4As shown, the water purifier generates pure water after deep filtration and purification of the stabilized water, which flows through the pure water inlet 1143 of the diverter 1 again and flows into the water outlet chamber 1148. Through the cooperation between the water outlet chamber 1148 and the diverter assembly 17, the pure water can be actually allocated and flow out from the first water supply port 1144 to the tankless pipeline machine, and from the second water supply port 1145 to the faucet. During the diversion of the pure water, the excess pure water in the water outlet chamber 1148 can flow back to the reflux chamber 1146 under the regulation of the diverter assembly 17 to form excess water. The reflux chamber 1146 can merge the stabilized water after the pressure is stabilized by the pressure regulating assembly 16 with the excess water refluxed by the diverter assembly 17, and output it to the water purifier from the raw water outlet 1142.

[0095] Next, the specific structure of the voltage regulating assembly 16 will be described in detail with reference to the accompanying drawings.

[0096] Please combine the specific Figure 3 , Figure 4 and Figure 5 As shown, the pressure regulating assembly 16 can divide the water inlet cavity 1147 into an air cavity 1153 and a liquid cavity 1611. Specifically, the space enclosed by the valve body upper shell 116 and the pressure regulating assembly 16 is formed into the air cavity 1153, and the pressure regulating assembly 16 is provided with a water injection guide hole 1612 and a pressure regulating water outlet 1613, and the water injection guide hole 1612 and the pressure regulating water outlet 1613 are both connected to the liquid cavity 1611.

[0097] For further details, please refer to Figure 3 , Figure 4 and Figure 5As shown, the inner wall of the air cavity 1153 is provided with a water injection conduit portion 1154 connected to the raw water inlet 1141 extending toward the inside of the air cavity 1153, and the water injection conduit portion 1154 is inserted into the water injection guide hole 1612 of the pressure regulating assembly 16. Specifically, a water injection flow channel 1155 connected to the raw water inlet 1141 is provided inside the water injection conduit portion 1154, and the water injection conduit portion 1154 is connected to the liquid cavity 1611 through the water injection flow channel 1155, and the port of the water injection flow channel 1155 used to connect to the liquid cavity 1611 is a water passing port. The valve housing 11 is provided with a pressure reducing chamber outlet 1151, so that the liquid chamber 1611 can be connected to the reflux chamber 1146 through the pressure reducing chamber outlet 1151, and the water pressure of the liquid chamber 1611 near the pressure regulating outlet 1613 is equal to the water pressure in the reflux chamber 1146, that is, the outlet pressure of the pressure regulating outlet 1613 of the pressure regulating assembly 16 is equivalent to the water pressure of the pressure-stabilized water delivered to the water purifier, and the water pressure of the liquid chamber 1611 near the water injection guide hole 1612 is equal to the water pressure of the water supply pipeline, that is, the inlet pressure of the water injection guide hole 1612 of the pressure regulating assembly 16 is the water pressure of the water supply pipeline. Since the pressure regulating assembly 16 includes a pressure regulating execution end arranged inside the liquid chamber 1611. In this way, when a pressure difference is formed between the pressure regulating water outlet 1613 and the water injection guide hole 1612, the pressure regulating component 16 can produce a relative displacement along the central axis of the water injection conduit portion 1154 to change the throttling distance between the water passing port and the pressure regulating execution end.

[0098] Understandable, such as Figure 5 As shown, the whole process of tap water flowing into the liquid cavity 1611 is as follows: after the tap water flows into the water injection channel 1155 from the raw water inlet 1141, it will flow through the water port, the water injection guide hole 1612, the pressure regulating outlet 1613, the pressure reducing cavity outlet 1151 and flow to the reflux cavity 1146. When the outlet pressure of the pressure regulating assembly 16 increases (such as turning off the water purifier), the pressure on the side of the pressure regulating outlet 1613 will drive the pressure regulating assembly 16 to move along the central axis of the water injection conduit portion 1154 and toward the side close to the water port, and the pressure regulating execution end of the pressure regulating assembly 16 moves toward the water port, so that the throttling distance between the water port and the pressure regulating execution end is reduced, that is, the flow area between the water port and the pressure regulating execution end through which the tap water can pass is reduced until it reaches the position of force balance. When the outlet pressure drops (such as when the water purifier is activated), the pressure on one side of the water injection guide hole 1612 will drive the pressure regulating assembly 16 to move along the central axis of the water injection conduit portion 1154 and toward the side away from the water port. The pressure regulating actuator end of the pressure regulating assembly 16 moves away from the water port, thereby increasing the throttling distance between the water port and the pressure regulating actuator end until the pressure regulating actuator end is in a force balance state again.

[0099] Therefore, as the outlet pressure changes, the pressure regulating assembly 16 automatically makes corresponding displacements to change the throttling distance between the water port and the pressure regulating execution end, so as to achieve the purpose of stabilizing the pressure, thereby ensuring that the pressure supplied to the water purifier remains basically unchanged. The structure is simple and compact, which is more convenient for subsequent disassembly and maintenance work by maintenance personnel. In addition, since the water injection conduit portion 1154 is inserted into the water injection guide hole 1612 of the pressure regulating assembly 16, not only does it make the pressure regulating assembly 16 more stable during the displacement process, but it can also ensure that the pressure regulating execution end moves accurately toward or away from the water port, thereby accurately adjusting the throttling distance between the water port and the pressure regulating execution end, so as to achieve the purpose of accurately regulating the pressure. In the process of assembling the pressure regulating assembly 16 to the valve housing 11, the water injection conduit portion 1154 can also insert and position the pressure regulating assembly 16, so as to improve the assembly efficiency and positioning accuracy.

[0100] The unexpected effect is that please combine Figure 3 and Figure 5 As shown, the tap water flowing in from the raw water inlet 1141 flows into the liquid chamber 1611 under the guidance of the water injection channel 1155, but does not fill the entire water inlet chamber 1147, which not only makes the pressure regulation response more timely and accurate, but also can further reduce the probability of tap water leaking 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.

[0101] Please refer to the specific Figure 3 As shown, the pressure regulating assembly 16 includes a valve core assembly 162 and an elastic pressure regulating elastic member 163, that is, the pressure regulating elastic member 163 is made of a material that can be elastically deformed (such as silicone, rubber, etc.), the water injection guide hole 1612 and the pressure regulating water outlet 1613 are both arranged on the valve core assembly 162, and the valve core assembly 162 and the pressure regulating elastic member 163 are detachably connected to facilitate the disassembly and assembly of the valve core assembly 162 and the pressure regulating elastic member 163. If the pressure regulating elastic member 163 is damaged or loses its elasticity during long-term use, the pressure regulating elastic member 163 can be replaced separately, thereby reducing the maintenance cost of the pressure regulating assembly 16. Figure 4 As shown, the pressure regulating elastic member 163 is connected between the valve body upper shell 116 and the valve body lower shell 117. Further, when a pressure difference is formed between the pressure regulating water outlet 1613 and the water injection guide hole 1612, the pressure regulating elastic member 163 can be deformed, and the valve core assembly 162 forms a relative slide along the extension direction of the water injection conduit portion 1154.

[0102] It can be understood that when the outlet pressure on the pressure-regulating water outlet 1613 side of the valve core assembly 162 increases, under the action of the outlet pressure, the pressure-regulating elastic member 163 produces elastic deformation toward the side close to the water port, and at the same time, it also cooperates with the valve core assembly 162 to move along the central axis of the water injection conduit portion 1154 and toward the side close to the water port. When the inlet pressure on the water injection guide hole 1612 side of the valve core assembly 162 decreases, under the action of the outlet pressure and the deformation recovery of the pressure-regulating elastic member 163, the pressure-regulating elastic member 163 resets toward the side away from the water port, and at the same time, it also cooperates with the valve core assembly 162 to move along the central axis of the water injection conduit portion 1154 and toward the side away from the water port.

[0103] As a preferred method of this embodiment, please refer to Figure 5 As shown, the valve core assembly 162 includes a valve core limiting sleeve 1621 and a valve core base 1622, wherein the valve core limiting sleeve 1621 is provided with a first guide hole 16121, and the valve core base 1622 is provided with 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 portion 1154 can be sequentially inserted into the first guide hole 16121 and the second guide hole 16122, and the pressure regulating water outlet 1613 is provided on the valve core base 1622. Further, as Fig.12 and Fig.13 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 member 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 threadedly connected to the external thread section 1625, and the valve core limiting sleeve 1621 is threadedly fixed to the valve core base 1622, which not only realizes the purpose of detachable connection between the valve core assembly 162 and the pressure regulating elastic member 163, but also makes the assembly more convenient and efficient.

[0104] Specifically, Figure 5 As shown, the inner diameter of the port of the valve core limit sleeve 1621 near the end of the pressure regulating elastic member 163 is larger than the diameter of the valve core base 1622, so the valve core limit sleeve 1621 near the end of the pressure regulating elastic member 163 and the outer side wall of the valve core base 1622 cooperate to form a clamping space. Fig.12 , Fig.13 and Fig.14As shown, the above-mentioned pressure-regulating elastic member 163 includes an elastic member body 1631, and a clamping protrusion 1632 extending from the elastic member body 1631 toward the clamping space, wherein the elastic member body 1631 and the clamping protrusion 1632 both extend along the circumference of the valve core base 1622, and the end of the elastic member body 1631 close to the valve core base 1622 and the clamping protrusion 1632 are formed into an elastic sleeve hole 164, the valve core base 1622 is inserted into the elastic sleeve hole 164 of the pressure-regulating elastic member 163, and the clamping protrusion 1632 is clamped between the valve core limit sleeve 1621 and the valve core base 1622. With such a configuration, the valve core limit sleeve 1621 and the valve core base 1622 cooperate to clamp the pressure-regulating elastic member 163, making the connection between the pressure-regulating elastic member 163 and the valve core assembly 162 more stable, thereby ensuring that during the elastic deformation of the pressure-regulating elastic member 163 and the movement of the valve core assembly 162, the pressure-regulating elastic member 163 and the valve core assembly 162 will not be separated, thereby improving the stability of the pressure-regulating assembly 16 during operation.

[0105] Further, please refer to Fig.14 As shown, the clamping protrusion 1632 is provided with a second fastening protrusion 16332, and the second fastening protrusion 16332 is integrally formed with the clamping protrusion 1632, so that the second fastening protrusion 16332 is clamped between the clamping protrusion 1632 and the valve core limiting sleeve 1621, thereby increasing the friction resistance between the clamping protrusion 1632 and the valve core limiting sleeve 1621, and effectively preventing the clamping protrusion 1632 from escaping from the clamping space. Of course, the second fastening protrusion 16332 can also be provided on the valve core limiting sleeve 1621, and the valve core limiting sleeve 1621 and the second fastening protrusion 16332 are integrally formed, which can also increase the friction resistance between the clamping protrusion 1632 and the valve core limiting sleeve 1621.

[0106] Further, please refer to Fig.14 As shown, the clamping protrusion 1632 is further provided with a third fastening protrusion 16333, the third fastening protrusion 16333 is integrally formed with the clamping protrusion 1632, and the third fastening protrusion 16333 is clamped between the clamping protrusion 1632 and the valve core base 1622, thereby increasing the friction resistance between the clamping protrusion 1632 and the valve core base 1622, and further preventing the clamping protrusion 1632 from escaping 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 friction resistance between the clamping protrusion 1632 and the valve core base 1622.

[0107] 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 escaping from the clamping space, but also enable the clamping protrusion 1632 to be more compactly assembled in the clamping space.

[0108] In addition, please refer to Figure 5 As shown, the pressure regulating assembly 16 also includes a valve core sealing ring 165, a valve core limiting sleeve 1621 and a valve core base 1622 cooperate to form a valve core sealing cavity, and the valve core sealing ring 165 is sleeved on the water injection conduit portion 1154 and embedded in the valve core sealing cavity to better prevent tap water from leaking into the air cavity 1153 from between the water injection guide hole 1612 and the water injection conduit portion 1154.

[0109] In this embodiment, in order to ensure that the pressure regulating elastic member 163 can be connected between the valve body upper shell 116 and the valve body lower shell 117 more quickly and more firmly, the inventor provides a preferred method. Figures 1 to 5 As shown, the elastic member body 1631 is clamped between the valve body upper shell 116 and the valve body lower shell 117. Fig.14 As shown, the valve body lower shell 117 is provided with a housing slot, which extends along the circumference of the valve body lower shell 117, and the pressure regulating elastic member 163 extends toward the inside of the housing slot to form a sealing buckle 1635, which extends along the slot length direction of the housing slot, and the sealing buckle 1635 is inserted into the housing slot. Such a configuration can not only ensure that the pressure regulating elastic member 163 is more compactly and firmly clamped on the valve housing 11, but also achieve the premise of facilitating the assembly of the pressure regulating assembly 16, and the pressure regulating assembly 16 is more firmly installed on the valve housing 11. At the same time, it also ensures the sealing of the connection position between the pressure regulating elastic member 163 and the valve housing 11, prevents water from seeping out of the valve housing 11, and also avoids the problem of water infiltrating into the air cavity 1153 and causing the parts in the air cavity 1153 to rust and fail. It should be noted that the shell slot can also be provided on the valve body upper shell 116, or the valve body upper shell 116 and the valve body lower shell 117 are both provided with shell slots, which can be set and adjusted according to structural design and design requirements.

[0110] Further, please refer to Fig.14As shown, the sealing buckle part 1635 is provided with a first fastening protrusion 16331, and the first fastening protrusion 16331 is integrally formed with the sealing buckle part 1635, so that the first fastening protrusion 16331 is sandwiched between the sealing buckle part 1635 and the housing slot, thereby increasing the friction resistance between the sealing buckle part 1635 and the housing slot, so that the sealing buckle part 1635 is more firmly inserted into the housing slot, and the sealing buckle part 1635 is better prevented from being separated from the housing slot. Of course, the first fastening protrusion 16331 can also be provided on the slot wall of the housing slot, which can also increase the friction resistance between the sealing buckle part 1635 and the housing slot.

[0111] As a preferred method of this embodiment, see Fig.14 As shown, the elastic member body 1631 is provided with a deformation adjustment groove 1634, which is in a U-shaped structure, and the notch of the deformation adjustment groove 1634 is preferably oriented toward the air cavity 1153. Figure 5 As shown, the deformation adjustment groove 1634 is formed by bending the elastic member body 1631 between the valve core base 1622 and the valve housing 11, and the deformation adjustment groove 1634 extends along the circumference of the valve core base 1622. This not only creates enough space for the elastic member body 1631 during elastic deformation, but also provides a larger elastic deformation range within a limited space, thereby increasing the elastic capacity of the pressure regulating elastic member 163.

[0112] As a preferred method of this embodiment, please refer to Fig.12 As shown, the valve core base 1622 includes a valve flap plug 1623, and the valve flap plug 1623 serves as the pressure regulating execution end of the pressure regulating assembly 16. Fig.13 As shown, the valve flap plug 1623 is provided with a valve flap support beam 1624 extending toward the cavity wall of the liquid cavity 1611, and the valve flap 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. In order to ensure that the valve core base 1622 has good structural strength and facilitate the production of the valve core base 1622, the valve flap plug 1623, the valve flap support beam 1624 and the body of the valve core base 1622 are integrally formed. Among them, the valve flap support beam 1624 can be selected as one, and the valve flap support beam 1624 extends along the circumference of the valve flap plug 1623, and the valve flap support beam 1624 is evenly provided with a plurality of water flow holes along the circumference of the valve flap plug 1623, so that the pressure-stabilizing water can flow through the water flow holes. Alternatively, there are preferably multiple valve flap support beams 1624, which are evenly distributed around the valve flap plug 1623, and two adjacent valve flap support beams 1624 are arranged at intervals to facilitate the flow of pressure-stabilizing water through the valve flap plug 1623.

[0113] In order to avoid the valve plug 1623 and the water port of the water injection conduit 1154 from being in rigid contact and reduce the noise of the diverter 1, please refer to Figure 5 , Fig.12 and Fig.13 As shown, the valve flap plug 1623 includes a valve flap support 16231 and an elastic plug elastic member 16232. The plug elastic member 16232 can be made of silicone material. The valve flap support 16231 is provided with a valve flap embedding groove 16233 for embedding the plug elastic member 16232. The valve flap support 16231 is fixedly connected to the main body of the valve core base 1622 through a valve flap support beam 1624.

[0114] In this embodiment, please refer to Figures 3 to 5 As shown, the pressure regulating assembly 16 also includes a pressure regulating spring 166, which is located in the air cavity 1153, and 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 water outlet 1613 and the water injection guide hole 1612, the pressure regulating elastic member 163 and the pressure regulating spring 166 are both deformed.

[0115] On the one hand, during the pressure regulation process, the pressure regulating spring 166 can assist the pressure regulating elastic member 163 to return to the initial position or the equilibrium position after the pressure changes. That is, the pressure regulating spring 166 can use its own elastic force to push the pressure regulating elastic member 163 back to a certain position, and make the valve core assembly 162 move accordingly, returning to a state close to the 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 member 163, and then accurately control the outlet pressure. On the other hand, the pressure regulating spring 166 can share the pressure borne by the pressure regulating elastic member 163 to a certain extent, thereby avoiding the problem that when the inlet pressure is too high or the valve is frequently started and stopped, the pressure regulating elastic member 163 alone may be subjected to excessive deformation, fatigue failure, or even damage.

[0116] In addition, the combination of the pressure regulating spring 166 and the pressure regulating elastic member 163 can make the valve core assembly 162 respond to pressure changes more quickly. When the pressure changes, the elastic force of the pressure regulating spring 166 can cooperate with the deformation force of the pressure regulating elastic member 163 to accelerate the movement of the valve core assembly 162, that is, quickly adjust the throttling distance between the water port and the pressure regulating execution end, thereby improving the pressure regulating efficiency of the diverter 1.

[0117] For further details, please refer to Figures 3 to 5As shown, a pressure regulating limit platform 1194 is provided on the inner wall of the air cavity 1153 along the extension direction of the water injection conduit portion 1154. The extension length of the pressure regulating limit platform 1194 should be smaller than the extension length of the water injection conduit portion 1154. The end of the pressure regulating spring 166 is sleeved on the outside of the pressure regulating limit platform 1194 to achieve the purpose of limiting the pressure regulating spring 166 and improve the positioning accuracy and assembly efficiency of the pressure regulating spring 166 during the assembly process.

[0118] Preferably, please combine Figures 3 to 5 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 portion 1154, so that the pressure regulating execution end seals and closes the water passing port. That is, when the valve core assembly 162 moves along the central axis of the water injection conduit portion 1154 and toward the side close to the water passing port, when the valve core limit sleeve 1621 of the valve core assembly 162 abuts against the pressure regulating limit platform 1194, the plug elastic member 16232 of the valve core assembly 162 will also abut against the water passing port of the water injection conduit portion 1154, thereby increasing the bearing area and bearing capacity of the diverter 1.

[0119] Further, please refer to Figure 3 As shown, the valve housing 11 is also provided with a breathing hole 118, and the air cavity 1153 is connected to the outside of the valve housing 11 through the breathing hole 118, so that the pressure regulating assembly 16 can produce relative displacement along the central axis direction of the water injection conduit portion 1154. It can be understood that when the pressure regulating elastic member 163 and the pressure regulating spring 166 are deformed, the spatial pressure inside the air cavity 1153 will change. At this time, the air cavity 1153 is connected to the atmospheric pressure by using the breathing hole 118, which helps to maintain the pressure of the air cavity 1153 where the pressure regulating spring 166 is located stable, thereby avoiding the risk of excessive deformation and rupture caused by the pressure difference on both sides of the pressure regulating elastic member 163 exceeding the bearing capacity of the pressure regulating elastic member 163, thereby improving the service life of the pressure regulating assembly 16 and the diverter 1. In addition, the pressure in the air cavity 1153 is kept connected with the external environmental pressure through the breathing hole 118. In the process of reducing / regulating the pressure of tap water, it can effectively avoid the pressure dropping below the saturated vapor pressure of tap water to cause cavitation, thereby avoiding the vibration and noise of the diverter 1 due to the presence of bubbles.

[0120] Preferably, please refer to Figure 3As shown, the breathing hole 118 is provided on the valve body upper shell 116 of the valve shell 11, and the central axis of the breathing hole 118 is arranged parallel to the central axis of the water injection conduit portion 1154. With such an arrangement, from the perspective of stability, the consistent direction helps to maintain the equilibrium state of the air cavity 1153. During operation, when there is a slight fluctuation in pressure, the pressure regulating spring 166 will expand and contract according to the pressure change, and the position of the breathing hole 118 allows the gas to enter and exit in time, and cooperates with the action of the pressure regulating spring 166 and the pressure regulating elastic member 163 to quickly adjust the internal pressure. In terms of the accuracy of pressure regulation, when the breathing hole 118 and the pressure regulating spring 166 are in the same expansion and contraction direction, during the pressure change process, the path of the gas entering and exiting the breathing hole 118 is more matched and coordinated with the path of the internal space change caused by the expansion and contraction of the pressure regulating spring 166, which will be able to more accurately control the pressure reduction range.

[0121] Further, please refer to Figure 3 As shown, the breathing hole 118 is arranged on one side of the upper shell 116 of the valve body close to the edge, and the breathing hole 118 extends along the extension direction of the water injection conduit portion 1154 to the side of the upper shell 116 of the valve body close to the pressure regulating assembly 16, which will effectively ensure that the inner hole wall of the breathing hole 118 is more flat and smooth, so that the flow state of the gas passing through the breathing hole 118 is more stable, and the unstable phenomenon of local turbulence of the gas is effectively avoided, thereby ensuring that the air cavity 1153 can more accurately sense the change in pressure and more accurately adjust the pressure, thereby improving the accuracy of pressure regulation. Of course, the flat inner hole wall is not easy to accumulate impurities. In some working environments, the fluid may carry tiny particulate impurities, which are easy to gather at the protrusions, and may cause the breathing hole 118 to be blocked over time. The flat inner hole wall makes it difficult for impurities to adhere and accumulate, which can effectively ensure the smoothness of the breathing hole 118, ensure the normal breathing function of the air cavity 1153, and then ensure the stable operation of the entire diverter 1.

[0122] As a preferred method of this embodiment, please refer to Figure 6 and Figure 7As shown, a limit support column 1191 is provided on the valve body lower shell 117 of the valve housing 11, and the limit support column 1191 is preferably located directly below the valve disc plug 1623, and the limit support column 1191 is convexly arranged toward the liquid chamber 1611, and the pressure regulating execution end of the pressure regulating assembly 16 can abut against the limit support column 1191, so that the diverter 1 can limit the pressure regulating execution end of the valve core assembly 162 when it is not in use or when the outlet pressure drops, that is, the limit support column 1191 can support the valve core assembly 162. At this time, the throttling distance between the pressure regulating execution end and the water port of the water injection channel 1155 is the largest. Furthermore, an anti-sticking protrusion 1192 is provided at the end of the limit support column 1191 close to the pressure regulating execution end, so that a gap is formed between the limit support column 1191 and the pressure regulating execution end. This is equivalent to reducing the contact area between the limit support column 1191 and the pressure regulating execution end. It can also be understood that the pressure regulating execution end does not directly contact the end of the limit support column 1191. Therefore, when scale accumulation occurs at the end of the limit support column 1191, the pressure regulating execution end will not adhere to the limit support column 1191, thereby effectively preventing the diverter 1 from having a pressure regulating failure.

[0123] For further details, please refer to Figure 6 and Figure 7 As shown, the anti-sticking protrusion 1192 is distributed at the edge position of the end of the limiting support column 1191 and is extended along the circumference of the limiting support column 1191. The anti-sticking protrusion 1192 is preferably extended along the circumference of the limiting support column 1191 to form an arc-shaped structure. Then, tap water flowing through the limiting support column 1191 can clean the end of the limiting support column 1191 by itself, thereby reducing the probability of scale accumulation at the end of the limiting support column 1191.

[0124] It should be noted that the anti-sticking protrusion 1192 can also be set on the pressure regulating execution end, that is, the anti-sticking protrusion 1192 is set on the valve flap support 16231 of the valve flap plug 1623.

[0125] Preferably, a groove 1193 may be further provided at the end of the position-limiting support column 1191, and the anti-sticking protrusion 1192 is located on the side of the groove 1193. Such a configuration is equivalent to effectively increasing the gap distance between the position-limiting support column 1191 and the pressure-adjusting execution end, thereby further preventing the pressure-adjusting execution end from sticking to the position-limiting support column 1191, and improving the stability of the pressure adjustment of the diverter 1.

[0126] Furthermore, if Fig.15As shown, at least one conducting hole 16234 is provided on a side wall of the valve flap support 16231 close to the limiting support column 1191, which not only facilitates embedding the plug elastic member 16232 in the valve flap embedding groove 16233 of the valve flap support 16231 and pushing the plug elastic member 16232 out of the valve flap embedding groove 16233 of the valve flap support 16231, but also further reduces the contact area of ​​the pressure regulating execution end.

[0127] In the above, the water outlet chamber 1148 cooperates with the diverter component 17 to distribute the pure water purified by the water purifier, and the excess pure water inside the water outlet chamber 1148 can flow back to the reflux chamber 1146 under the regulation of the diverter component 17 to form excess water, thereby effectively preventing the water pressure from fluctuating greatly during the sudden activation of the tankless pipeline machine and / or the faucet, causing the water purifier to start and stop frequently.

[0128] Next, the specific structure of the above-mentioned flow dividing component 17 is described in detail in conjunction with the drawings.

[0129] The flow dividing component 17 is provided with a flow hole, which is used to guide the pure water flowing in from the pure water inlet 1143 to pass through the flow dividing component 17 and enter the water outlet chamber 1148. Fig.17 The diversion component 17 divides the water outlet chamber 1148 into a lower water outlet chamber 11481 and an upper water outlet chamber 11482. The above-mentioned pure water inlet 1143 and the second water supply port 1145 are both connected to the lower water outlet chamber 11481, and the upper water outlet chamber 11482 is connected to the first water supply port 1144. The upper water outlet chamber 11482 is connected to the lower water outlet chamber 11481 through the flow hole. At this time, after the pure water flows from the pure water inlet 1143 into the lower water outlet chamber 11481 for buffering and storage, another part of it will flow to the upper water outlet chamber 11482 through the flow hole, and finally flow out from the first water supply port 1144.

[0130] In addition, if Fig.24As shown, the valve housing 11 has a reflux guide portion 1171 , which is located inside the water outlet cavity 1148 , and a guide flow channel 1172 communicating with the reflux cavity 1146 is disposed inside the reflux guide portion 1171 . Specifically, the reflux guide portion 1171 is arranged on the lower shell 117 of the valve body, and the reflux guide portion 1171 is extended toward the water outlet chamber 1148, wherein the guide channel 1172 extends to the port of the water outlet lower chamber 11481 and connects to the water outlet lower chamber 11481, and the diverter component 17 can abut the reflux guide portion 1171, and according to the pressure difference formed by the pure water inlet 1143, the first water supply port 1144, and the second water supply port 1145, the diverter component 17 can generate a relative displacement toward the side of the first water supply port 1144, so that the diverter component 17 is separated from the reflux guide portion 1171, and then excessive pure water will be able to flow from the guide channel 1172 into the reflux chamber 1146 to form the above-mentioned excess water.

[0131] In this way, when the faucet is used alone, pure water will flow from the pure water inlet 1143 into the water outlet lower cavity 11481, and then flow out directly from the second water supply port 1145 from the water outlet lower cavity 11481. At this time, the diversion component 17 abuts against the reflux guide portion 1171 to seal the guide channel 1172, so that pure water will not flow back to the guide channel 1172.

[0132] When the water tankless pipeline machine uses water alone, pure water flows from the pure water inlet 1143 into the water outlet lower chamber 11481, flows through the flow hole and enters the water outlet upper chamber 11482, and finally flows out from the first water supply port 1144 to the water tankless pipeline machine. At this time, the pressure on the side of the diverter assembly 17 close to the first water supply port 1144 is less than the pressure on the side of the diverter assembly 17 facing away from the first water supply port 1144, that is, the water pressure formed by the pure water inlet 1143 and the second water supply port 1145 is greater than the water pressure on the side of the first water supply port 1144. The diverter assembly 17 can produce a relative displacement toward the first water supply port 1144, so that the diverter assembly 17 is separated from the reflux guide portion 1171, and the excess pure water flows back to the guide channel 1172. It can be understood that the water output of the first water supply port 1144 is determined by the water pump and the negative pressure valve of the water tankless pipeline machine.

[0133] When the tankless pipeline machine is turned off, the flow splitter assembly 17 will be reset toward the side of the reflux guide portion 1171, and the flow splitter assembly 17 will be re-contacted on the reflux guide portion 1171 to re-seal the guide channel 1172. Therefore, the flow splitter 1 can flexibly respond to the water flow distribution requirements when the tankless pipeline machine uses water alone, so that the purified water can reasonably handle the excess water while meeting the water needs of the tankless pipeline machine, without causing waste of water resources, and avoiding the risk of damaging the tankless pipeline machine due to excessive water pressure.

[0134] When the tankless pipeline machine and the faucet use water at the same time, after the pure water flows from the pure water inlet 1143 into the water outlet lower cavity 11481, a part of the pure water flows out from the second water supply port 1145 to the faucet, and the other part of the pure water enters the water outlet upper cavity 11482 through the flow hole and flows out from the first water supply port 1144 to the tankless pipeline machine. Due to the reduction in water pressure on the side of the second water supply port 1145, the pressure on the side of the diverter component 17 close to the first water supply port 1144 is not much different from the pressure on the side of the diverter component 17 facing away from the first water supply port 1144. At this time, the diverter component 17 abuts against the reflux guide part 1171, and the excess pure water will hardly flow to the guide channel 1172. In this way, the tankless pipeline machine and the faucet can use water normally, ensuring the stable operation of the entire drinking water purification system.

[0135] Therefore, because only the tankless pipeline machine is enabled, the excess pure water can flow back, which can prevent the water purifier from frequently adjusting its working state due to sudden changes in the water consumption of the tankless pipeline machine (such as changes in water pressure caused by frequent opening and closing of the tankless pipeline machine). For example, if there is no reflux mechanism, when the tankless pipeline machine is suddenly closed, the instantaneous change in water pressure may have an impact on the internal structure and working pressure of the water purifier, and with the reflux mechanism, it can buffer this water pressure change to a certain extent and reduce the pressure of frequent start and stop of the water purifier. In the case of simultaneous water use, a relatively stable water flow distribution state is maintained by the action of the diverter component 17. If there is no diverter component 17, and the faucet and the tankless pipeline machine are working at the same time, a sudden change in the water consumption of one party (such as the sudden closing of the faucet) may cause a large fluctuation in the water pressure inside the water purifier, causing the water purifier to frequently adjust its working state. The diverter component 17 can maintain a relatively stable water pressure and water flow distribution, reducing the frequent start and stop of the water purifier caused by changes in external water use.

[0136] In the related art, the above-mentioned flow holes can be elastically expanded and contracted, and the flow rate of pure water flowing through the flow holes can be adjusted by the slight deformation of these flow holes. That is, when the water consumption of the water tankless pipeline machine increases, the flow holes become larger as the pressure difference on both sides of the diversion component 17 increases, and the flow rate of pure water increases. When the water consumption of the water tankless pipeline machine decreases, the flow holes shrink under the action of their own rebound force, and the flow rate of pure water decreases, thereby automatically maintaining the pressure difference on both sides of the diversion component 17 and delaying the resetting of the diversion component 17. However, since the deformation of the flow hole is limited, the maximum and minimum flow ranges that it can adjust will also be greatly limited. For example, when the water consumption of the water terminal varies greatly, it is limited by the shape and size of the flow hole and the deformation, and the flow hole with a small deformation alone will not be able to meet the actual flow regulation needs.

[0137] Based on this, an embodiment of the present application provides a flow splitter assembly 17, which aims to solve the problem in the related art that the flow splitter 1 is limited by the deformation of the flow hole, so that the maximum and minimum flow ranges that can be adjusted are limited.

[0138] Please refer to the specific Fig.16 As shown, the flow dividing component 17 has a flexible check portion 1721 provided with a flow regulating port 1722, and the flexible check portion 1721 can control the opening and closing size of its flow regulating port 1722 according to the pressure difference formed by the pure water inlet 1143, the first water supply port 1144, and the second water supply port 1145, so as to adjust the amount of increase of the pure water flowing into the water outlet cavity 1148. The amount of increase here should be understood as the physical quantity that the volume flow of the pure water increases as the opening and closing size of the flow regulating port 1722 changes during the process of the pure water flowing through the flow regulating port 1722. That is, the flexible check portion 1721 is elastic, and when the water output from the first water supply port 1144 is large, the pressure difference formed by the pure water inlet 1143, the first water supply port 1144, and the second water supply port 1145 is large, and the flow regulating port 1722 of the flexible check portion 1721 can be opened, then the water outlet upper chamber 11482 will also be connected to the water outlet lower chamber 11481 through the flow regulating port 1722, and the cross-sectional area of ​​the flow regulating port 1722 will increase with the increase of the pressure difference until it opens to the maximum deformation state of the flow regulating port 1722, then the opening and closing size of the flow regulating port 1722 will change from zero to the maximum, so that the volume flow rate (hereinafter referred to as flow rate) of pure water that can pass through the flow regulating port 1722 is increased from zero to the maximum, so that part of the pure water will also be replenished into the water outlet upper chamber 11482 through the flow regulating port 1722. It can be understood that when the pressure difference decreases, the flow regulating port 1722 will be able to reduce itself under deformation recovery until it is completely closed. At this time, pure water will hardly flow through the flow regulating port 1722.

[0139] Therefore, when the water consumption of the water terminal varies greatly, the elastic deformation of the flexible check portion 1721 can be used to change the amount of pure water flowing into the water outlet chamber 1148, thereby effectively solving the problem that the existing diverter 1 is limited by the deformation of the flow hole, which limits the maximum and minimum flow ranges that can be adjusted. In addition, once the opening of the flow regulating port 1722 is adjusted, the flow rate of pure water is relatively stable. During long-term use, compared with only setting a retractable flow hole, the risk of blockage can be reduced, thereby better ensuring the stability of the diverter assembly 17 and the diverter 1, and reducing the cost of processing and manufacturing and the cost of subsequent maintenance.

[0140] It should be noted that the elastically retractable flow hole is matched with the flexible check portion 1721 , that is, the flow hole and the flexible check portion 1721 are provided on the diverter assembly 17 at the same time.

[0141] Next, the specific structure of the above-mentioned flow dividing component 17 is described in detail in conjunction with the drawings.

[0142] Please refer to the specific Fig.24 As shown, the diverter assembly 17 includes a diverter balancing membrane 172 and a balancing spring 171. The diverter balancing membrane 172 is detachably connected between the valve body upper shell 116 and the valve body lower shell 117. In addition, the valve body upper shell 116 and the diverter balancing membrane 172 cooperate to form an upper water outlet cavity 11482. The valve body lower shell 117 and the diverter balancing membrane 172 cooperate to form a lower water outlet cavity 11481. The balancing spring 171 is arranged between the diverter balancing membrane 172 and the inner cavity wall of the upper water outlet cavity 11482.

[0143] Among them, see Figures 17 to 21 , the shunt balance membrane 172 is made of elastic material (such as silicone, rubber and other materials), and a diaphragm through hole 1724 is provided on the shunt balance membrane 172. The above-mentioned flow hole is a diaphragm through hole 1724. At this time, the flow hole can also be elastically retracted. Further, the above-mentioned flexible check portion 1721 is arranged on the shunt balance membrane 172, and the flexible check portion 1721 cooperates with the flow hole to achieve more accurate flow control. When the flow demand of pure water is small, a small pressure difference may cause the flow hole to deform, which plays a role in finely adjusting the flow and improving the adjustment accuracy of the shunt component 17 and the diverter 1. When the flow demand of pure water is large, the flexible check portion 1721 can be deformed under the action of a large pressure difference, allowing a large amount of pure water to pass through. This combination is equivalent to a multi-stage adjustment system, which can accurately adjust the flow through the diverter 1 according to different working conditions (such as different water use speeds of water tankless pipeline machines), and very effectively reduces the probability of frequent start and stop of the water purifier. At the same time, through the synergistic effect of the flow holes on the splitter balance membrane 172 and the flexible check portion 1721, the pressure balance on both sides of the splitter assembly 17 can be better maintained. That is, they can flexibly adjust their own states according to the size of the pressure difference on both sides, so that the distribution of pure water in the water outlet cavity 1148 is more stable, which helps to improve the reliability and service life of the splitter 1 and reduce the damage to its components and system failures caused by pressure imbalance.

[0144] In this way, when the water consumption of the tankless pipeline machine is large, the pressure on the side of the diverter balance membrane 172 close to the first water supply port 1144 is greatly different from the pressure on the side of the diverter assembly 17 facing away from the first water supply port 1144, and the diverter balance membrane 172 will produce elastic deformation toward the side of the first water supply port 1144 and compress the balance spring 171. When the water consumption of the tankless pipeline machine decreases, the pressure difference on both sides of the diverter balance membrane 172 decreases, and almost no pure water flows through the first water supply port 1144, which means that there is no corresponding pressure condition generated by the flow of pure water. At this time, the state of both sides of the diverter balance membrane 172 is restored to the initial equilibrium state. Then, under the action of the elastic deformation of the diverter balance membrane 172 itself and the elastic deformation of the balance spring 171, the diverter balance membrane 172 recovers its deformation on the side facing away from the first water supply port 1144 until the diverter balance membrane 172 abuts against the flexible check portion 1721 to seal the guide flow channel 1172. Such settings will have the following unexpected effects:

[0145] 1. When the water consumption of the tankless pipeline machine is large, the pressure on the side of the diverter balance membrane 172 close to the first water supply port 1144 is greatly different from the pressure on the side of the diverter assembly 17 facing away from the first water supply port 1144. The diverter balance membrane 172 will produce elastic deformation toward the side of the first water supply port 1144 and compress the balance spring 171. At this time, the balance spring 171 plays a buffering role and absorbs part of the pressure to prevent the diverter balance membrane 172 from being damaged due to excessive instantaneous pressure. When the water consumption of the tankless pipeline machine decreases, the pressure difference on both sides of the diverter balance membrane 172 decreases. Since the balance spring 171 stores elastic potential energy after being compressed, the balance spring 171 will release the elastic potential energy to help the diverter balance membrane 172 recover from deformation on the side facing away from the first water supply port 1144.

[0146] 2. The elastic properties of the shunt balance membrane 172 can automatically adjust the size of the flow hole according to the change of the pressure difference. The balance spring 171 cooperates with it to more finely control the deformation degree of the shunt balance membrane 172, thereby improving the shunt accuracy of the shunt 1. For example, when the pressure difference changes slightly, the slight deformation of the shunt balance membrane 172 and the slight expansion and contraction of the balance spring 171 work together to more accurately adjust the amount of pure water flowing through, thereby better realizing the function of automatically maintaining the pressure difference on both sides of the shunt balance membrane 172.

[0147] 3. During the use of the entire water purification system, the water consumption of the water tankless pipeline machine changes dynamically. The balance spring 171 and the diverter balance membrane 172 cooperate with each other to effectively adjust the pressure balance inside the water purification system under different water use conditions. This cooperation enables the diverter 1 to adapt to complex and changeable working conditions, reduces system failures caused by factors such as sudden pressure changes, enhances the stability and reliability of the system, and extends the service life of the diverter 1. In addition, when the water consumption of the water tankless pipeline machine changes rapidly, the synergistic effect of the balance spring 171 and the diverter balance membrane 172 can enable the diverter 1 to respond quickly. For example, when the water consumption of the water tankless pipeline machine suddenly increases, the balance spring 171 can quickly buffer the deformation of the diverter balance membrane 172, causing the flexible check portion 1721 to quickly increase and increase the water flow rate. When the water consumption of the water tankless pipeline machine suddenly decreases, the two can reset the diverter balance membrane 172 in time to reduce the flow of pure water, thereby optimizing the dynamic response capability of the diversion process.

[0148] It should be added that the specific Fig.21 As shown, the flexible check portion 1721 is a duckbill structure, and a duckbill cavity 1723 is arranged inside the flexible check portion 1721. The duckbill cavity 1723 penetrates the flow-dividing balance membrane 172 and forms a duckbill cavity opening on the side of the flow-dividing balance membrane 172 facing away from the flexible check portion 1721. For details, see Figures 17 to 21 The flexible check portion 1721 includes a duckbill deformation portion 17211 and a base portion 17212 fixedly connected to the shunt balancing membrane 172. The duckbill deformation portion 17211, the base portion 17212, and the shunt balancing membrane 172 are integrally formed to facilitate processing and manufacturing, and can also ensure the integrity of the shunt balancing membrane 172, so that the shunt balancing membrane 172 has good comprehensive performance (such as elasticity, etc.). The duckbill deformation portion 17211 is formed from the base portion 1721 2 is convexly arranged toward the water outlet upper cavity 11482, and the cross-sectional area of ​​the duckbill deformation portion 17211 gradually decreases along the convex direction, and the cross-sectional area here is parallel to the large surface of the diverter balancing membrane 172, and the large surface of the diverter balancing membrane 172 is the side surface with the largest area in the diverter balancing membrane 172, and the flow regulating port 1722 is arranged on the end of the duckbill deformation portion 17211 away from the diverter balancing membrane 172, and the duckbill cavity 1723 is connected to the flow regulating port 1722.

[0149] As a preferred method of this embodiment, please refer to Fig.16 , Fig.17 , Fig.18 and Fig.21As shown, the above-mentioned shunt assembly 17 also includes a diaphragm top cover 173, and a top cover through hole 1731 is provided on the diaphragm top cover 173. The top cover through hole 1731 is connected to the diaphragm through hole 1724. At this time, the top cover through hole 1731 and the diaphragm through hole 1724 constitute the above-mentioned flow hole. The diaphragm top cover 173 is arranged on the side of the shunt balance membrane 172 close to the first water supply port 1144, and the above-mentioned flexible check portion 1721 protrudes toward one side of the diaphragm top cover 173 and penetrates the diaphragm top cover 173, that is, as shown in FIG. Fig.17 and Fig.18 As shown, a top cover through hole 1732 is provided on the diaphragm top cover 173, and the duckbill deformation portion 17211 of the flexible check portion 1721 passes through the top cover through hole 1732 toward the water outlet upper chamber 11482 and protrudes from the top cover through hole 1732, and one end of the balance spring 171 abuts against the inner cavity wall of the water outlet upper chamber 11482, and the other end of the balance spring 171 abuts against the diaphragm top cover 173. In this way, the diaphragm top cover 173 serves as a supporting point of the balance spring 171, and the diaphragm top cover 173 has good structural strength. During the diversion process, the balance spring 171 can adjust the balance of the system through the force between the diaphragm top cover 173 and the inner cavity wall. For example, when the flow rate of pure water changes or the internal pressure of the water outlet upper chamber 11482 fluctuates, the balance spring 171 can be retracted and retracted according to the position change of the diaphragm top cover 173, thereby adjusting the pressure balance and flow balance of the diverter 1 to ensure the stability of the diversion.

[0150] Further, please refer to Fig.16 As shown, the flow diverter assembly 17 has a stop limiter 1733 protruding toward the first water supply port 1144, and the flow diverter assembly 17 generates a relative displacement toward the first water supply port 1144 until the stop limiter 1733 abuts against the inner wall of the water outlet cavity 1148, specifically, the stop limiter 1733 abuts against the inner wall of the water outlet upper cavity 11482. At this time, the flow diverter assembly 17 is the maximum displacement generated by the flow diverter assembly 17. In this way, when the flow diverter assembly 17 is under a large pressure difference, the stop limiter 1733 can abut against the inner wall of the water outlet upper cavity 11482, forming a reliable mechanical limit, effectively limiting the further movement of the flow diverter assembly 17, thereby preventing the flow diverter balancing membrane 172 from being excessively deformed due to excessive force, eliminating the hidden danger of damage to the flow diverter balancing membrane 172 due to excessive deformation, and improving the service life of the diverter 1.

[0151] Preferably, please combine Fig.17 , Fig.18 and Fig.21As shown, the stopper 1733 is arranged on the diaphragm top cover 173, and the stopper 1733 is preferably formed integrally with the diaphragm top cover 173, and the stopper 1733 can withstand the impact force generated by the collision with the inner wall of the water outlet upper cavity 11482. Because the diaphragm top cover 173 has good structural strength, it can ensure that the stopper 1733 will not be easily deformed or damaged during frequent displacement and collision, so as to better maintain the stability and accuracy of the entire diverter 1. In other embodiments, the stopper 1733 can also be arranged on the diverter balance membrane 172.

[0152] The unexpected effect is that Figures 17 to 21 As shown, the stop limiter 1733 is located on the outside of the balance spring 171, and the stop limiter 1733 is extended along the circumference of the balance spring 171 to constrain the end of the balance spring 171 to the inside of the stop limiter 1733 to ensure the stability of the balance spring 171 during the deformation process. It should be noted that the inner diameter of the stop limiter 1733 can be selected to match the outer diameter of the balance spring 171. Of course, the inner diameter of the stop limiter 1733 can also be larger than the outer diameter of the balance spring 171. In addition, a spring limiter column 1734 can be protruded on the side of the diaphragm top cover 173 facing the first water supply port 1144, and the end of the balance spring 171 is sleeved on the spring limiter column 1734, so that the stop limiter 1733 can be used to achieve the purpose of double limitation of the balance spring 171. In addition, the spring limiter column 1734 can also quickly position the balance spring 171 during the assembly process to improve the assembly efficiency.

[0153] Further, please refer to Fig.17 As shown, the stop limit portion 1733 is provided with an escape opening 1735 corresponding to the flexible non-return portion 1721. Fig. 20 As shown, the avoidance opening 1735 preferably passes through the stop limit portion 1733 along the protruding direction of the stop limit portion 1733, so that the stop limit portion 1733 is formed into two arc-shaped and oppositely arranged stop portions, and the number of the flexible non-return portions 1721 is configured to be two, and each flexible non-return portion 1721 is located between the two stop portions. Such a configuration will have the following unexpected technical effects:

[0154] 1. The avoidance opening 1735 provides space for the flexible check portion 1721, which not only enables the flexible check portion 1721 to normally protrude toward one side of the diaphragm top cover 173 and penetrate therethrough, but also ensures that each flexible check portion 1721 is deformed according to the water flow pressure within a limited space, thereby flexibly adjusting the diversion of the water flow.

[0155] 2. Under the action of the avoidance opening 1735, the flexible check portion 1721 on the diaphragm top cover 173 and the shunt balancing membrane 172 can avoid mutual extrusion and friction during operation, effectively reducing the interference and wear between the flexible check portion 1721 and the stop limit portion 1733, thereby increasing the service life of the shunt assembly 17. The reliability and durability of the shunt balancing membrane 172 and the shunt assembly 17 are improved.

[0156] 3. If the number of flexible check parts 1721 is configured as two, they can work together when facing different water flow pressures and flow conditions. For example, when the water flow impacts the diversion balance membrane 172, if there is only one flexible check part 1721, it may be deformed to one side due to the uneven impact of the water flow, resulting in unstable diversion. The two relatively distributed flexible check parts 1721 will be able to balance this impact force with each other. When the flexible check part 1721 on one side is subject to a large water flow pressure and tends to open, the flexible check part 1721 on the other side can make corresponding adjustments according to the pressure difference, thereby maintaining the stability of the diversion, making the water flow out of the first water supply port 1144 more uniform and stable.

[0157] 4. Under the action of the avoidance port 1735, when the stop limit portion 1733 abuts against the inner wall of the water outlet upper cavity 11482, the purified water can still flow to the first water supply port 1144 through the avoidance port 1735, thereby ensuring the smoothness, stability and continuity of the flow of purified water, and effectively preventing the purified water from being blocked by the stop limit portion 1733 and causing a sudden change in the water flow pressure, thereby ensuring the stability and reliability of the use of the diverter 1 and the drinking water purification system.

[0158] Considering that when the stop limit part 1733 abuts against the inner wall of the water outlet upper cavity 11482, the water output of the first water supply port 1144 is relatively large, that is, the demand for pure water of the water tankless pipeline machine is large. In order to further ensure the supply of pure water, a water passing notch 1736 is provided on the stop limit part 1733, that is, each stop part of the stop limit part 1733 is provided with a water passing notch 1736 near one end of the first water supply port 1144. This embodiment does not limit the shape and size of the water passing notch 1736, and can be adjusted according to design requirements and structural design. Then, part of the pure water can also flow to the first water supply port 1144 through the water passing notch 1736, thereby ensuring that sufficient pure water flows to the first water supply port 1144 and is supplied to the water tankless pipeline machine.

[0159] Of course, it should also be noted that, in addition to the stop limiter 1733 on the diverter assembly 17 abutting against the inner wall of the water outlet upper cavity 11482, the specific Fig.24As shown, the inner cavity wall of the water outlet upper cavity 11482 is convexly formed with a stop boss 1161 toward the side of the diverter assembly 17. Specifically, the stop boss 1161 is a convexly formed inner cavity wall of the water outlet upper cavity 11482 toward the side of the diverter assembly 17. The stop boss 1161 is preferably integrally formed with the valve body upper shell 116 for easy production. The inside of the stop boss 1161 is provided with a first water supply channel 1162 connected to the first water supply port 1144, and the stop limit portion 1733 can abut against the stop boss 1161.

[0160] On the one hand, the stop boss 1161 cooperates with the stop limiter 1733 on the diaphragm top cover 173 to more accurately limit the deformation degree of the diverter balance membrane 172. When the diverter balance membrane 172 is deformed toward the first water supply port 1144 under the influence of factors such as water flow and water pressure, the stop limiter 1733 abuts against the stop boss 1161, thereby further preventing the diverter balance membrane 172 from excessive deformation, and better ensuring that the diverter balance membrane 172 works within a safe range. On the other hand, pure water will be orderly diverted to the first water supply port 1144 through the first water supply channel 1162, so that the water flow is more concentrated and stable to flow to the target outlet, avoiding water flow turbulence, thereby improving the working efficiency and accuracy of the diverter 1.

[0161] Preferably, please refer to Fig.24 As shown, the inner wall of the flow channel of the first water supply channel 1162 is convexly formed with a spring force-bearing body 1163, and the spring force-bearing body 1163 can be optionally extended along the circumference of the first water supply channel 1162, or the number of the spring force-bearing bodies 1163 is configured to be multiple, each spring force-bearing body 1163 can be optionally hemispherical or prism-shaped, and multiple spring force-bearing bodies 1163 are arranged along the circumference of the first water supply channel 1162. Fig.16 As shown, the end of the balance spring 171 is inserted into the first water supply channel 1162, and the end of the balance spring 171 abuts against the spring force body 1163. At this time, the spring force body 1163 provides a fixed support point for the end of the balance spring 171, so that the position of the balance spring 171 is more stable during the operation, that is, the end of the balance spring 171 abuts against the spring force body 1163, and the peripheral side of the balance spring 171 can contact the inner wall of the flow channel of the first water supply channel 1162, which well avoids the vibration or slight displacement that may be generated by the balance spring 171 during the operation, thereby better ensuring that the balance spring 171 can normally play its balancing and regulating functions, and transmit force more accurately, ensuring and improving the diversion accuracy of the diverter 1.

[0162] Of course, in order to facilitate the assembly of the end of the balance spring 171 into the first water supply channel 1162, see Fig.24The port of the first water supply channel 1162 used to connect to the upper water outlet cavity 11482 is the second guide port, and a positioning guide portion 1164 is provided on the second guide port. The positioning guide portion 1164 is obliquely connected to the inner wall of the flow channel of the first water supply channel 1162 along the central axis direction of the first water supply channel 1162. During the assembly of the balance spring 171, it is only necessary to abut the end of the balance spring 171 against the positioning guide portion 1164. Under the guidance of the positioning guide portion 1164, the balance spring 171 will slide into the first water supply channel 1162 by itself, thereby achieving the purpose of self-positioning and improving the assembly efficiency and convenience of the flow balance spring 171.

[0163] As another preferred method of this embodiment, please refer to Fig.17 , Fig.18 as well as Fig.19 As shown, the shunt assembly 17 further includes a diaphragm base 174, on which a base through hole 1741 is provided, and the base through hole 1741 is connected to the diaphragm through hole 1724. It can be understood that when the shunt assembly 17 is not equipped with the diaphragm top cover 173, the base through hole 1741 and the diaphragm through hole 1724 constitute the above-mentioned flow hole. Alternatively, when the shunt assembly 17 is equipped with the above-mentioned diaphragm top cover 173, the shunt balance membrane 172 is sandwiched between the diaphragm top cover 173 and the diaphragm base 174, and the top cover through hole 1731, the diaphragm through hole 1724, and the base through hole 1741 constitute the above-mentioned flow hole. The diaphragm base 174 is arranged on the side of the shunt balance membrane 172 facing away from the first water supply port 1144. In this way, when the pure water flow rate flowing out of the first water supply port 1144 suddenly decreases, if the water inlet flow rate of the water purifier fails to make corresponding adjustments in time, the pressure of the water outlet upper chamber 11482 will rise rapidly. In this case, the diaphragm base 174 can provide strong support for the shunt balance membrane 172. The diaphragm base 174 has a certain structural strength. Due to the support of the diaphragm base 174, the shunt balance membrane 172 will not be excessively deformed toward the side of the reflux guide 1171 due to reverse pressure. Thereby ensuring the stability and reliability of the entire shunt assembly 17, avoiding blockage or other failures caused by excessive deformation of the shunt balance membrane 172, ensuring that the water purifier can operate continuously and stably under different working conditions, effectively improving the working efficiency and service life of the water purifier, and also providing users with a more reliable water purification experience.

[0164] It can be understood that the "pressure difference formed by the pure water inlet 1143, the first water supply port 1144, and the second water supply port 1145" recorded above is also equivalent to the difference between the pressure on the side of the diaphragm top cover 173 and the pressure on the side of the diaphragm base 174, that is, the pressure difference on both sides of the diversion balancing membrane 172.

[0165] For further details, please refer to Figure 17 to Figure 18As shown, a base avoidance hole 1742 is also provided on the diaphragm base 174, and the size of the base avoidance hole 1742 is larger than the diameter of the reflux guide portion 1171, and the reflux guide portion 1171 can pass through the base avoidance hole 1742 to abut against the shunt balance membrane 172. In this embodiment, the shape of the base avoidance hole 1742 is not specifically limited, for example, it can be selected as a circular hole, or a square hole, or an elliptical hole, etc. In this way, the shunt balance membrane 172 will be able to accurately seal the guide flow channel 1172, thereby effectively blocking the reflux path of pure water. This also ensures that under normal shunt working conditions, the water flow can flow in an orderly manner according to the predetermined shunt channel, avoiding the unwarranted loss or reflux of pure water interfering with the normal water outlet process. At the same time, the flexibility of the shunt balance membrane 172 is utilized to improve the sealing between the shunt balance membrane 172 and the reflux guide portion 1171.

[0166] It should be noted that if Fig.21 As shown, the diaphragm base 174 is provided with a base water flow port 1743 connected to the flow regulating port 1722. That is, the base water flow port 1743 on the diaphragm base 174 is correspondingly arranged and connected to the duckbill cavity 1723 of the flexible check portion 1721, ensuring that the purified water can pass through the base water flow port 1743 and flow into the duckbill cavity 1723, and when the flow regulating port 1722 is opened, the purified water will be able to pass through the flow regulating port 1722 and flow into the water outlet upper cavity 11482.

[0167] As another preferred method of this embodiment, please refer to Fig.21 As shown, the diaphragm top cover 173 extends a flow guide extension body 175 toward the diaphragm through hole 1724. The flow guide extension body 175 is preferably formed integrally with the diaphragm top cover 173. The flow guide extension body 175 is provided with a water through hole 1751 through the inside. The through hole here should be understood as the water through hole 1751 passing through both ends of the flow guide extension body 175 along the extension direction of the flow guide extension body 175. The flow guide extension body 175 is inserted into the diaphragm through hole 1724. At this time, the top cover through hole 1731, the diaphragm through hole 1724, the base through hole 1741 and the water through hole 1751 constitute the flow hole. In the process of pure water flowing through the water through hole 1751, it is equivalent to pure water flowing from the water outlet lower chamber 11481 through the base through hole 1741, the diaphragm through hole 1724 and the top cover through hole 1731 in sequence, and finally flowing into the water outlet upper chamber 11482.

[0168] Such a configuration not only plays a good guiding role in the flow of pure water through the water through hole 1751, but also makes the flow of pure water in the through hole more orderly and smooth, reducing the turbulence and energy loss of the water flow. At the same time, the tight and orderly connection structure between the various components, during the assembly process, uses the guide extension body 175 to accurately plug the diaphragm through hole 1724 of the shunt balance membrane 172 and the base through hole 1741 of the diaphragm base 174, thereby improving the positioning accuracy and assembly efficiency.

[0169] Furthermore, please combine Figures 18 to 21 As shown, the flow guide extension body 175 passes through the top cover through hole 1731, the diaphragm through hole 1724, and the base through hole 1741 in sequence and extends out of the base through hole 1741. The part of the flow guide extension body 175 extending out of the base through hole 1741 is provided with a snap protrusion 1752, and the snap protrusion 1752 is snapped on the diaphragm base 174, so as to realize the snap connection between the diaphragm top cover 173 and the diaphragm base 174, so as to ensure that the shunt balance membrane 172 is clamped between the diaphragm top cover 173 and the diaphragm base 174, which is conducive to the convenience and efficiency of disassembly and assembly, thereby facilitating the replacement of subsequent components. And the structure is simple, reducing the processing cost of each component. Of course, the side of the diaphragm base 174 facing away from the shunt balance membrane 172 can be provided with a base slot, and the snap protrusion 1752 is snapped in the base slot.

[0170] Preferably, the flow guide extension 175 is located inside the top cover through hole 1731, and a buffer gap is formed between the flow guide extension 175 and the hole wall of the top cover through hole 1731. This not only ensures that the assembler can observe the diaphragm through hole 1724 of the shunt balance membrane 172 through the buffer gap during the assembly process, which is convenient for assembly positioning and further improves assembly efficiency. At the same time, the buffer gap serves as a space for the flow guide extension 175 to deform during the clamping process, thereby facilitating the clamping protrusion 1752 to be clamped on the diaphragm base 174 or to detach the clamping protrusion 1752 from the diaphragm base 174.

[0171] It should be noted here that, in other embodiments, the flow guide extension body 175 can also be extended from the diaphragm base 174 toward the diaphragm through hole 1724, then the flow guide extension body 175 passes through the base through hole 1741, the diaphragm through hole 1724, the top cover through hole 1731 in sequence and extends out of the top cover through hole 1731, and the part of the flow guide extension body 175 extending out of the top cover through hole 1731 is provided with a snap protrusion 1752, and the snap protrusion 1752 is snapped onto the diaphragm top cover 173, which belongs to the conventional replacement method of the above-mentioned preferred embodiment.

[0172] It should also be noted that if Fig.21As shown, the diameter of the water through hole 1751 gradually increases along the direction of water flow. According to the above description, it can be known that the direction of water flow is the direction from the base through hole 1741 to the diaphragm through hole 1724 and the top cover through hole 1731 in sequence. Therefore, that is, the diameter of the water through hole 1751 gradually increases along the first direction, and the first direction is from one side of the diaphragm base 174 along the central axis of the water through hole 1751 and toward the side of the diaphragm top cover 173. In this way, when pure water flows in from the side with a smaller diameter and then flows out from the other side with a larger diameter, the cross-sectional area of ​​the water through hole 1751 gradually increases. According to the flow formula Q=vA (Q is the flow rate, v is the flow rate, and A is the cross-sectional area), when the flow rate remains basically unchanged, the cross-sectional area increases and the flow rate decreases. A lower flow rate can reduce the pressure loss of water flow in the water through hole 1751. At the same time, when pure water flows into the water through hole 1751 from a smaller diameter to one side, a relatively orderly flow state can be formed. As the diameter gradually increases, the purified water has enough space to smoothly transition, reducing the turbulence caused by sudden spatial changes, thereby effectively avoiding the generation of small bubbles in the purified water. In addition, the smaller diameter side can also limit the impact of the water flow, thereby reducing physical damage to the water through hole 1751 and the diversion balance membrane 172, such as scratches.

[0173] In the above, the pressure on the side of the shunt balance membrane 172 close to the first water supply port 1144 is significantly different from the pressure on the side of the shunt assembly 17 facing away from the first water supply port 1144. The shunt balance membrane 172 will produce elastic deformation toward the first water supply port 1144, and drive the membrane top cover 173 and / or the membrane base 174 to move toward the first water supply port 1144. In order to ensure and increase the amount of elastic deformation that the shunt balance membrane 172 will produce toward the first water supply port 1144, such as Figures 18 to 21 As shown, a deformation groove 1725 is provided on the flow-dividing balancing membrane 172, and the deformation groove 1725 is a U-shaped groove. The deformation groove 1725 is located outside the flexible check portion 1721, and the deformation groove 1725 is extended along the circumference of the membrane top cover 173. It can be understood that the direction of the notch of the deformation groove 1725 can be set and adjusted according to the structural design and design requirements. In this embodiment, the notch of the deformation groove 1725 is preferably set toward the water outlet lower cavity 11481.

[0174] In this way, when the shunt balancing membrane 172 is subjected to pressure, the circumferentially extending deformation groove 1725 can provide sufficient space for the deformation of the shunt balancing membrane 172, which not only makes the stress concentrated in the deformation groove 1725, but also makes the stress effectively released and produces uniform deformation, thereby well avoiding the risk of excessive concentration of stress in other parts of the shunt balancing membrane 172 and causing rupture and fatigue damage. At the same time, it can also effectively enhance the deformation ability of the shunt balancing membrane 172 in a limited space. When the shunt balancing membrane 172 is affected by the pressure change in the water outlet cavity 1148, the deformation groove 1725 can be used as a pre-set deformation area to better guide the shunt balancing membrane 172 to produce a larger deformation, so that the shunt balancing membrane 172 can make a sensitive response according to these pressure differences, so as to achieve the purpose of better balancing the pressure in all directions, which is conducive to the shunt component 17 to more accurately control the shunt.

[0175] Further, please refer to Figures 18 to 21 As shown, the groove wall of the deformation groove 1725 away from the flexible check portion 1721 is protruded toward the outside and is formed with a diaphragm clamping portion 1726. Preferably, the diaphragm clamping portion 1726 is arranged on the groove wall of the deformation groove 1725 close to the groove mouth side, and the diaphragm clamping portion 1726 is integrally formed with the shunt balancing membrane 172. The diaphragm clamping portion 1726 is extended along the groove length direction of the deformation groove 1725. The diaphragm clamping portion 1726 is clamped between the valve body upper shell 116 and the valve body lower shell 117, thereby achieving the purpose of detachably connecting the shunt balancing membrane 172 between the valve body upper shell 116 and the valve body lower shell 117, thereby improving the assembly efficiency of the diverter 1.

[0176] Specifically, Fig.24 As shown, a diaphragm clamping groove 1173 is provided on the valve body lower shell 117, and the diaphragm clamping portion 1726 is embedded in the diaphragm clamping groove 1173, so that the diaphragm clamping portion 1726 is more firmly connected between the valve body upper shell 116 and the valve body lower shell 117, and the flow-dividing balancing membrane 172 can be more firmly assembled on the valve housing 11. In addition, the groove wall of the diaphragm clamping groove 1173 close to the flexible check portion 1721 is extended toward the inside of the deformation groove 1725, that is, the groove wall of the diaphragm clamping groove 1173 close to the flexible check portion 1721 is received in the deformation groove 1725, so that the flow-dividing assembly 17 and the valve housing 11 are more compact, which is conducive to reducing the volume of the diverter 1. It should be noted that in addition to the diaphragm clamping groove 1173 being provided on the valve body lower shell 117, the diaphragm clamping groove 1173 is provided on the valve body upper shell 116.

[0177] Preferably, if Fig.24As shown, the valve body upper shell 116 is provided with a diaphragm anti-slip groove 1165, and the diaphragm clamping portion 1726 is provided with a diaphragm anti-slip body 1727 plugged into the diaphragm anti-slip groove 1165, which further improves the stability of the connection between the split flow balancing membrane 172 and the valve housing 11. It can be understood that the diaphragm clamping groove 1173 is provided on the valve body upper shell 116, and the diaphragm anti-slip groove 1165 is correspondingly provided on the valve body lower shell 117.

[0178] In the drinking water purification system, when the user starts or shuts down the tankless pipeline machine, the flow velocity of the pure water flowing through the diverter 1 changes dramatically, thus generating a water hammer phenomenon. The instantaneous pressure wave generated by the water hammer may damage the diverter assembly 17 in the diverter 1. Based on this, the inventor also provides a preferred method, see Fig.17 and Fig.16 The diverter 1 further includes a water hammer absorber 18, which is located between the diverter assembly 17 and the pure water inlet 1143, and is detachably connected to the valve housing 11. Specifically, the water hammer absorber 18 is installed inside the water outlet lower chamber 11481, so that the pressure wave generated by the water hammer has been buffered before entering the water outlet upper chamber 11482.

[0179] Such a configuration can buffer the pressure wave before it reaches the diverter assembly 17, reduce the risk of damage to the diverter assembly 17 caused by the high pressure generated by the water hammer, and increase the service life of the diverter assembly 17. At the same time, since the water hammer absorber 18 absorbs part of the energy, it can reduce the vibration and noise generated by the water flow impacting the valve housing 11. In addition, under the action of the water hammer absorber 18, the stability of the diverter assembly 17 during the adjustment process can be guaranteed, the interference of the water hammer on the diverting process can be reduced, the normal operation of the diverter 1 can be ensured, and the diverting accuracy of the diverter 1 can be improved.

[0180] Preferably, please refer to Fig.24 As shown, a plurality of water flow buffer holes 181 are provided on the water hammer absorber 18, and the plurality of water flow buffer holes 181 are evenly distributed, and the water outlet cavity 1148 is connected to the pure water inlet 1143 through the plurality of water flow buffer holes 181. When pure water flows into and passes through the water hammer absorber 18 with the water flow buffer holes 181 from the pure water inlet 1143, the water flow buffer holes 181 play a role in buffering the water flow. Because when the pure water flows through the water flow buffer holes 181, its flow direction and speed will change. For example, when the fast-flowing pure water passes through the plurality of water flow buffer holes 181, it will be dispersed into multiple small water flows and consume part of the kinetic energy of the water flow, thereby reducing the degree of sudden change in the water flow speed and alleviating the possibility of water hammer.

[0181] In addition, the presence of the water flow buffer hole 181 can also adjust the pressure change of the water flow. According to the Bernoulli principle, when the water flows through the water flow buffer hole 181, its pressure will form a certain pressure difference on both sides of the water hammer absorber 18, which plays a certain degree of regulation. At the same time, due to the presence of the water flow buffer hole 181, the pure water will have a certain flow under the action of the pressure difference. This flow can alleviate the sharp rise in pressure, make the pressure change more gentle, and further reduce the water hammer phenomenon.

[0182] It should be noted that the present application does not limit the number, size and distribution of the water flow buffer holes 181, which can be set and adjusted according to the structural design and design requirements. By reasonably setting the number, size and distribution of the water flow buffer holes 181, the pulse frequency of the pure water flow can also be changed. For example, when water hammer occurs, high-frequency pressure pulses will appear. The water flow buffer holes 181 are configured in a combination of large holes and small holes, wherein the large holes allow a larger flow of water to pass through, and the small holes have more restrictions on the water flow. Therefore, high-frequency pressure pulses can be converted into relatively low-frequency pulses (that is, irregular pulses become more regular), and the low-frequency, regular pressure changes have relatively small impacts on the diverter 1, which is also conducive to reducing the harm of water hammer.

[0183] For further details, please refer to Fig.24 and Fig.25 As shown, the water hammer absorber 18 is provided with a positioning assembly hole 182 for inserting the backflow guide 1171, and the aperture of the positioning assembly hole 182 is adapted to the diameter of the backflow guide 1171, so that the backflow guide 1171 can be quickly and firmly installed on the valve body lower shell 117 of the valve housing 11. In order to ensure that the water hammer absorber 18 can be more firmly installed on the valve body lower shell 117, and to make the force between the water hammer absorber 18 and the valve body lower shell 117 more balanced, the inner wall of the water outlet lower cavity 11481 is convexly formed with an absorber boss 1174, and the edge of the water hammer absorber 18 abuts against the absorber boss 1174, which has a simple structure and is easy to disassemble and assemble, which is conducive to subsequent maintenance and repair.

[0184] Of course, please refer to Fig.25 As shown, the absorbing member boss 1174 is formed with a limiting convex portion 1175 protruding toward one side of the diverter assembly 17, and the edge of the water hammer absorbing member 18 is provided with a limiting notch 183 for inserting the limiting convex portion 1175. In this way, the limiting notch 183 cooperates with the limiting convex portion 1175 to prevent the water hammer absorbing member 18 from deflecting around the reflux guide portion 1171, thereby guiding the pure water flow more stably.

[0185] In some other embodiments, the water hammer absorber 18 may be a piston-type water hammer arrester or a diaphragm-type water hammer arrester, both of which are relatively mature existing technologies in water hammer arresters, and their structures are not described in detail here. Alternatively, the water hammer absorber 18 may be a slow-closing check valve.

[0186] As the preferred method of this embodiment, please refer to Fig. 22 , Fig.23 and Fig.24 As shown, the diverter 1 also includes a water filter 19, the valve body lower shell 117 of the valve shell 11 is provided with a water inlet channel 1176, the water outlet lower chamber 11481 of the water outlet chamber 1148 is connected to the pure water inlet 1143 through the water inlet channel 1176, the water filter 19 is arranged in the water inlet channel 1176, the water filter 19 is provided with a filter hole 191 in the extension direction of the water inlet channel 1176, and a water gap is formed between the peripheral side wall of the water filter 19 and the inner side wall of the water inlet channel 1176, the peripheral side wall of the water filter 19 is provided with a drainage opening 192 connected to the water gap, and the opening size of the drainage opening 192 is larger than the aperture of the filter hole 191.

[0187] In this arrangement, since the filter holes 191 provided on the water filter element 19 can perform re-filtration in the flow direction of the pure water, small particles that may appear when the water purifier filter element is nearing the end of its service life are prevented from flowing into the water outlet cavity 1148 and the tankless pipeline machine, thereby ensuring and improving the purity of the pure water supplied to the tankless pipeline machine and the faucet, and improving the taste and quality of drinking water.

[0188] More importantly, when pure water passes through the filter hole 191 of the water filter 19, due to the relatively small aperture of the filter hole 191, the water flow will generate a certain resistance when passing through the filter hole 191. The presence of the drainage port 192 can play a role in diversion. The opening size of the drainage port 192 is larger than the aperture of the filter hole 191. A part of the water can flow through the drainage port 192 and the water gap, sharing part of the water flow, so that the water flow speed through the filter hole 191 will not be too high, thereby reducing the water resistance of this part. At the same time, the presence of the drainage port 192 and the water gap also helps to balance the pressure in the water inlet channel 1176. The water can redistribute the flow between the filter hole 191 and the drainage port 192, making the pressure distribution in the entire water inlet channel 1176 more uniform, and also reducing the water resistance of the water inlet channel 1176 and the entire diverter 1.

[0189] Preferably, see Fig. 22 , Fig.23 and Fig.24The water filter 19 includes a body fastening portion 193 and a body water filter portion 194 fixedly connected to the body fastening portion 193. The fixed connection here is preferably formed in one piece to facilitate production. The drainage port 192 and the filter hole 191 are both arranged on the body water filter portion 194. Specifically, the body water filter portion 194 has a water filter portion bottom wall and a water filter portion side wall extending along the circumference of the water filter portion bottom wall, and the water filter portion bottom wall and the water filter portion side wall cooperate to form a filter cavity, and the filter cavity has a filter cavity port arranged opposite to the water filter portion bottom wall. Among them, the filter hole 191 is arranged on the water filter portion bottom wall, the drainage port 192 is arranged on the water filter portion side wall, the body fastening portion 193 is arranged on the side of the water filter portion side wall close to the filter cavity port, and the body fastening portion 193 is arranged to extend along the circumference of the filter cavity port. The main body fastening portion 193 is formed by staggered protrusions toward the outer side of the water filter portion side wall. When the water filter 19 is inserted into the water inlet channel 1176, the main body fastening portion 193 can be detachably connected to the valve body lower shell 117 of the valve shell 11, and the main body water filter portion 194 and the inner side wall of the water inlet channel 1176 automatically form a water gap.

[0190] It should be noted that the drainage opening 192 is a drainage group, which includes a plurality of drainage holes arranged along the circumference of the main body water filter 194, and the aperture of each drainage hole is larger than the aperture of the filter hole 191. The drainage group can be configured as one group or multiple groups. Multiple drainage groups are evenly arranged along the extension direction of the water inlet channel 1176. Or, as Fig.23 As shown, the drainage opening 192 may also be in the form of a strip hole, and the drainage opening 192 is extended along the circumferential portion of the main body water filter 194. The number of the drainage opening 192 may be one or more, and the plurality of drainage openings 192 are arranged and distributed along the extension direction of the water inlet channel 1176, and two adjacent drainage openings 192 are preferably staggered.

[0191] Preferably, if Fig. 22As shown, a water filter buckle body 1177 is provided on the inner side wall of the water inlet channel 1176, and the water filter buckle body 1177 is provided along the circumferential direction of the water inlet channel 1176. The main body fastening part 193 is engaged with the water filter buckle body 1177, and the water filter buckle body 1177 extends along the extension direction of the water inlet channel 1176. Further, a fastening slot is provided on the water filter buckle body 1177, and a fastening protrusion 195 is provided on the main body fastening part 193, and the fastening slot is plug-connected with the fastening protrusion 195. In this way, it is effectively ensured that the water filter element 19 is stably installed and connected inside the water inlet channel 1176, and under the long-term impact of the water flow, the water filter element 19 will not be easily displaced, thereby ensuring that the filter hole 191 and the drainage port 192 can function normally and maintain the stability of the filtering function. At the same time, the water filter buckle body 1177 is snapped into the water filter slot, and the fastening slot is plugged into the fastening protrusion 195, making the installation of the water filter 19 more convenient. When assembling the diverter 1, the worker only needs to align the water filter 19 with the water inlet channel 1176 and perform the snap-in operation to complete the installation, which is also convenient for later disassembly, cleaning, replacement and maintenance. It should be noted that in addition to the above-mentioned fastening slot being set on the water filter buckle body 1177 and the fastening protrusion 195 being set on the main body fastening portion 193, the fastening slot can also be set on the main body fastening portion 193, and the fastening protrusion 195 is correspondingly set on the water filter buckle body 1177.

[0192] As a preferred mode of this embodiment, the diverter 1 also includes a water resistance member, which is used to increase the resistance of the water flow. The valve body lower shell 117 of the valve housing 11 is provided with a second water supply channel 1178, and the second water supply port 1145 is connected to the water outlet chamber 1148 through the second water supply channel 1178. The water resistance member is arranged in the second water supply channel 1178, and the water resistance member is detachably connected to the valve housing 11. Such a setting can effectively avoid pressure fluctuations caused by water flow impact. When the faucet is suddenly opened or closed, the rapid change of the water flow speed will produce a water hammer phenomenon, resulting in an instantaneous increase in the pressure in the second water supply channel 1178, and the resistance of the water resistance member to the water flow can slow down the sudden change of the water flow speed, thereby buffering this pressure change. At the same time, the water resistance member can also play a certain role in preventing backflow. When the pressure in the second water supply channel 1178 suddenly decreases, water backflow may occur. Since the water resistance member can increase the resistance of the backflow, the possibility of backflow is reduced.

[0193] In this embodiment, please refer to Fig. 22 and Fig.24As shown, a water-passing support frame 1131 having a support water outlet 1134 is provided on the valve body lower shell 117. Preferably, the water-passing support frame 1131 is preferably configured as two, and the two water-passing support frames 1131 are staggered, and the inner wall of the waterway of the second water supply channel 1178 cooperates with the two water-passing support frames 1131 to form four support water outlets 1134. The water-passing support frame 1131 is provided inside the second water supply channel 1178. The water-passing support frame 1131 is preferably formed integrally with the valve body lower shell 117, and the water resistance member abuts against and connects the water-passing support frame 1131. Further, a support positioning portion 1132 is provided on one side of the water-passing support frame 1131 facing the water outlet chamber 1148, and a water resistance plug for plugging the support positioning portion 1132 may be provided on the water resistance member, so that the water resistance member can be stably installed and fixed on the support positioning portion 1132.

[0194] Preferably, please Fig. 22 , Fig.24 and Fig.25 As shown, the inner wall of the flow channel of the second water supply channel 1178 is convexly provided with a bearing protrusion 1133, and the bearing protrusion 1133 is extended along the extension direction of the second water supply channel 1178. The water resistance member abuts against the bearing protrusion 1133, so that the water resistance member is more firmly installed inside the second water supply channel 1178. Furthermore, the cross-sectional area of ​​the bearing protrusion 1133 gradually increases from the side close to the water outlet cavity 1148 toward the side of the second water supply port 1145. In this way, in the molding process of manufacturing the valve body lower shell 117, the draft angle of the bearing protrusion 1133 is used to facilitate the separation of the mold and the valve body lower shell 117, and the bearing protrusion 1133 may be torn, deformed, and other defects during the demolding process, affecting the product quality. At the same time, since the cross-sectional area of ​​the bearing protrusion 1133 gradually increases, it is equivalent to a guiding role when installing the water resistance member. The water resistance member can more easily slide into the correct installation position along the draft angle direction, which is helpful for the installation of the water resistance member and makes the water resistance member more stable after installation. Because after the water resistance member is installed, the part with a larger cross-sectional area of ​​the bearing protrusion 1133 can limit the movement of the water resistance member in the flow channel direction to a certain extent. For example, when the water flow impacts the water resistance member, the water resistance member will not easily move along the flow channel direction, ensuring that the water resistance member stably and normally exerts resistance to the water flow. In addition, the bearing protrusion 1133 can better guide the flow of pure water. Since the cross-sectional area of ​​the bearing protrusion 1133 gradually increases, the water flow will change the flow direction more smoothly when passing through the bearing protrusion 1133, reducing the degree of turbulence of the water flow, thereby improving the stability and uniformity of the water flow.

[0195] As a preferred mode of this embodiment, the water resistance member includes a water resistance member body, and a plurality of flow-limiting water resistance holes are arranged on the water resistance member body, each of which is connected to the bracket water outlet 1134, and the water resistance member body is connected to the above-mentioned bearing protrusion 1133. In this way, when pure water passes through these flow-limiting water resistance holes, the water and air are fully mixed due to the resistance of the flow-limiting water resistance holes, which can not only reduce the flow rate of water, but also make the water flow out in the form of foam, and multiple flow-limiting water resistance holes are connected to the bracket water outlet 1134, which can also make the water flowing out of the water outlet more evenly dispersed, so as to save water and prevent water splashing. In some embodiments, the water resistance member can be selected as a one-way valve assembly, a throttle valve, or a bubbler.

[0196] The unexpected effect is that Fig.24 As shown, when the water hammer absorber 18 is installed in the lower water outlet cavity 11481, the water hammer absorber 18 will better completely confine the water resistance member in the second water supply channel 1178, ensuring the stability of the installation of the water resistance member. At the same time, since the water hammer absorber 18 is installed upstream of the water flow of the water resistance member, it can absorb and buffer the water hammer pressure wave before it reaches the water resistance member. This can protect the water resistance member and prevent the water resistance member from being damaged due to excessive water hammer pressure, ensuring that the water resistance member can normally perform its functions of limiting water flow and regulating pressure, and more accurately control the water flow according to the designed structure such as the flow-limiting water resistance hole, thereby providing a more stable water inlet condition for subsequent faucets or other water outlet equipment, reducing the impact of water hammer on the faucet, thereby extending the service life of the faucet and reducing the frequency of maintenance and replacement.

[0197] It should be noted that, in order to reduce the vibration of the water resistance member during the water resistance treatment process, a bearing slot for plugging and connecting the bearing protrusion 1133 may also be provided on the peripheral side wall of the water resistance member body. In addition, the aperture of the flow-limiting water resistance hole is between 0.5-1.5 mm to provide a relatively stable water flow resistance, thereby avoiding the risk of blockage during long-term use.

[0198] As a preferred mode of this embodiment, the diverter 1 also includes a water inlet filter, which is arranged at the raw water inlet 1141, wherein the water inlet filter is preferably a filter. In this way, it can effectively prevent some large particles of impurities (such as mud and sand, etc.) that may be contained in the tap water from flowing into the water inlet chamber 1147, thereby achieving the purpose of preliminary filtration, avoiding the risk of damage to the pressure regulating component 16 inside the diverter 1 and the risk of failure of the voltage stabilization of the diverter 1, and also reducing the total amount of impurities entering the water purifier, thereby extending the service life of the water purifier filter element to a certain extent. In conjunction with the water filter 19 arranged at the pure water inlet 1143, not only the purpose of double filtration of the diverter 1 is achieved, that is, although the pure water filtered by the water purifier has removed most of the impurities, bacteria and harmful substances, it may still be contaminated during the transportation process, such as particulate impurities generated by pipeline residues or aging. At this time, the water filter 19 can further intercept these impurities to ensure that the quality of the pure water flowing to each water terminal is purer. At the same time, the drinking water purification system also achieves the triple filtration effect on the water source, thereby effectively ensuring that the drinking water purification system has good water quality and providing users with safer drinking water.

[0199] In the above, the excess pure water in the water outlet chamber 1148 can flow back to the reflux chamber 1146 under the regulation of the diverter assembly 17. The reflux chamber 1146 can merge the pressure-stabilized water after the pressure-stabilized pressure-regulating assembly 16 with the excess water returned by the diverter assembly 17, and output it from the raw water outlet 1142 to the water purifier, so that the water source can be redistributed and utilized inside the drinking water purification system, reducing the waste of water source. However, when the amount of excess water returned from the water outlet chamber 1148 toward the reflux chamber 1146 is much smaller than the amount of pressure-stabilized water transported from the water inlet chamber 1147 toward the reflux chamber 1146, that is, the pressure on the side of the reflux chamber 1146 close to the water outlet chamber 1148 is smaller than the pressure on the side of the reflux chamber 1146 close to the water inlet chamber 1147, which easily causes the pressure-stabilized water entering the reflux chamber 1146 to flow back into the water outlet chamber 1148, thereby affecting the water quality of domestic water and direct drinking water.

[0200] Based on this, an optimal method is also disclosed in the embodiments of the present application. Figure 3As shown, the flow divider 1 also includes a one-way flow guide 13, which is arranged in the reflux chamber 1146 to prevent the pressure-stabilized water flowing through the water inlet chamber 1147 from flowing back to the water outlet chamber 1148 after being stabilized, and to output the excess water flowing back from the water outlet chamber 1148 to the reflux chamber 1146 to the water purifier after merging with the pressure-stabilized water. This not only prevents the pressure-stabilized water from flowing back to the water outlet chamber 1148 after being stabilized in the water inlet chamber 1147, causing the purified water in the water outlet chamber 1148 to be mixed with the pressure-stabilized water, but also ensures the water quality and quantity of the purified water supplied by the flow divider 1. At the same time, the pressure of both the water outlet chamber 1148 and the water inlet chamber 1147 is maintained, so that the water source flow in the water outlet chamber 1148, the water inlet chamber 1147 and the reflux chamber 1146 can be carried out in the designed direction and pressure conditions, so as to simplify the pipeline components and connections of the drinking water purification system while ensuring its stability.

[0201] An unexpected effect is that the one-way flow guide 13 is assembled in the reflux chamber 1146 of the valve housing 11, making the assembly between the one-way flow guide 13 and the valve housing 11 more compact. In a drinking water purification system with limited space, such an assembly method has a higher degree of integration, saves space, and very effectively simplifies the pipeline layout of the drinking water purification system, and reduces the risk of leakage due to too many pipe connections. In addition, it can also prevent the diverter 1 and the drinking water purification system from being damaged by the water hammer phenomenon. It can be understood that when the pressure of the external water supply pipeline increases instantly, the inertia of the water flow will cause a water hammer effect, generating a very high pressure wave. At this time, the one-way flow guide 13 can prevent this high-pressure wave from reversely impacting the one-way flow guide 13, which is beneficial to extend the service life of the diverter 1 and reduce the maintenance cost of the diverter 1 and the drinking water purification system.

[0202] As a preferred method of this embodiment, please refer to Figure 8 , Fig. 9 and Fig.10As shown, the above-mentioned one-way flow guide 13 includes a check body 131 and a mixed flow guide 132, wherein the check body 131 has an input port 1311 and an output port 1312, and the check body 131 is used to control the water source to flow from the input port 1311 to the output port 1312. It can be understood that the water source refers to the excess water that flows back from the water chamber 1148 toward the reflux chamber 1146. A flow guide channel 1321 is provided inside the mixing guide body 132. An extension portion 133 with a liquid injection port 1331 is provided on one side of the mixing guide body 132 protruding toward the check body 131. The extension portion 133 is extended along the circumferential portion of the mixing guide body 132 and is provided at the end of the mixing guide body 132. One end of the check body 131 provided with an output port 1312 abuts against the extension portion 133 to form a mixing chamber 1332. At this time, the opening formed by the mixing guide body 132, the extension portion 133 and the check body 131 is the liquid injection port 1331. The liquid 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.

[0203] For further details, please refer to Figure 6 and Figure 7 As shown, the injection port 1331 of the one-way flow guide 13 is arranged toward 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, so that the pressure-stabilized water flowing into the reflux chamber 1146 will flow into the mixing chamber 1332 through the injection port 1331. The input port 1311 of the check body 131 is connected to the water outlet chamber 1148, and the guide channel 1321 is connected to the raw water outlet 1142 of the valve body lower shell 117, so that excess water can only flow from the input port 1311 of the check body 131 and enter the mixing chamber 1332 through the output port 1312. At this time, the excess water is mixed with the pressure-stabilized water, and the excess water is guided to the raw water outlet 1142 by the guide channel 1321 after mixing with the pressure-stabilized water, and then transported to the water purifier. When the pressure in the mixing chamber 1332 is too high, that is, the pressure on the side of the reflux chamber 1146 close to the water outlet chamber 1148 is lower than the pressure on the side of the reflux chamber 1146 close to the water inlet chamber 1147, the check body 131 will close automatically under the action of the pressure, thereby preventing the stabilized pressure water from flowing back to the water outlet chamber 1148.

[0204] It should be supplemented that in order to ensure that the extension portion 133 can more stably abut against the end surface of the input port 1311 of the anti-return body 131, Figures 6 to 11As shown, the mixing flow guide 132 is provided with an auxiliary support portion 135 protruding toward one side of 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. One end of the auxiliary support portion 135 away from the mixing flow guide 132 abuts against the check body 131. In this way, the auxiliary support portion 135 and the extension portion 133 are both abutted against the check body 131, which not only realizes a more balanced force between the mixing flow guide 132 and the check body 131, but also increases the contact area between the mixing flow guide 132 and the check body 131, thereby ensuring the compactness and stability of the overall structure of the one-way flow guide 13.

[0205] Preferably, please combine Figure 6 and Figure 7 As shown, a positioning protrusion 1322 is provided on the outer side wall of the extension portion 133 , and the extending direction of the positioning protrusion 1322 is consistent with the extending direction of the guide channel 1321 . The positioning protrusion 1322 is located at one side of the liquid injection port 1331 . A positioning groove 1149 is provided on the valve housing 11, and the positioning groove 1149 is located inside the reflux chamber 1146, and the positioning groove 1149 extends along the extension direction of the reflux chamber 1146. When the one-way flow guide 13 is assembled into the reflux chamber 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 one-way flow guide 13 can align itself with the water inlet chamber 1147, that is, the pressure reduction chamber outlet 1151 is aligned with the injection port 1331, and the injection port 1331 fully covers the pressure reduction chamber outlet 1151, so that the pressure-stabilized water can flow more smoothly through the pressure reduction chamber outlet 1151 and the injection port 1331 and enter the mixing chamber 1332, thereby avoiding the problem of unstable water pressure caused by turbulence or eddy currents caused by the obstruction of the pressure-stabilized water.

[0206] In addition, during the process of assembling the one-way flow guide 13 into the reflux chamber 1146, it is only necessary to align the positioning protrusion 1322 of the one-way flow guide 13 with and slide it into the positioning groove 1149 inside the reflux chamber 1146, thereby improving the convenience and efficiency of assembling the one-way flow guide 13, facilitating the subsequent disassembly and maintenance of the one-way flow guide 13, improving the efficiency of repairing the diverter 1, and ensuring the stability of the diverter 1 during long-term use. Since the positioning protrusion 1322 is restricted by the positioning groove 1149, the one-way flow guide 13 is effectively prevented from being deflected and displaced in the reflux chamber 1146, thereby ensuring that the injection port 1331 of the one-way flow guide 13 is always aligned with the pressure relief chamber discharge port 1151 of the valve housing 11, thereby reducing the impact and vibration of the valve housing 11 by the pressure-stabilizing water, thereby reducing the noise of the diverter 1 during use.

[0207] For further details, please refer to Fig. 9 and Fig.10As shown, one end of the mixing flow guide 132 close to the extension 133 is the shoulder end of the mixing flow guide 132, and the shoulder end and the extension 133 are offset to form a shoulder portion 134. It can be understood that the cross-sectional dimension of the shoulder end is greater than the cross-sectional dimension of the extension 133, and the shoulder portion 134 is the portion where the shoulder end and the extension 133 are connected and the cross-sectional dimension changes. Figure 7 As shown, a step limit portion 1152 is provided on the valve housing 11, and the step limit portion 1152 is located inside the reflux chamber 1146, that is, the inner wall of the channel of the reflux chamber 1146 protrudes toward the inside of the reflux chamber 1146 to form the step limit portion 1152, and the shoulder end of the one-way flow guide 13 abuts against the step limit portion 1152 of the valve housing 11, then the shoulder portion 134 of the one-way flow guide 13 can enable the mixed flow guide 132 to move horizontally in the extension direction of the positioning protrusion 1322.

[0208] In this embodiment, the mixed flow guide 132 of the one-way flow guide 13 is inserted into the interior of the reflux chamber 1146 under the guidance of the positioning groove 1149 until the shoulder portion 134 abuts against the step limit portion 1152 of the valve housing 11, thereby limiting the movement of the mixed flow guide 132 in the extension direction of the reflux chamber 1146, thereby achieving the purpose of efficient positioning.

[0209] A drainage bottom slope 136 is arranged between the mixing chamber 1332 and the drainage bottom slope 136 extends obliquely from the mixing chamber 1332 to the inner wall of the flow channel of the diversion channel 1321. Such arrangement can not only avoid the height difference in the process of the pressure-stabilized water flowing from the mixing chamber 1332 to the diversion channel 1321, which causes a drastic change in a short time, generates a large impact force and the instability of local turbulence, but also ensures that the pressure-stabilized water is sequentially delivered to the mixing chamber 1332, the diversion channel 1321 and the raw water outlet 1142 to the water purifier at a relatively stable speed and state.

[0210] As a preferred method of this embodiment, please refer to Figure 8 and Fig. 9 As shown, the check body 131 includes a fixed shell 1313 and a valve core body 1314, the valve core body 1314 is movably arranged inside the fixed shell 1313, the input port 1311 and the output port 1312 are both arranged on the fixed shell 1313, and the valve core body 1314 can open and close the input port 1311 according to the pressure difference between the input port 1311 and the output port 1312. It can be understood that the water pressure on the side of the input port 1311 is equivalent to the pressure on the side of the reflux chamber 1146 close to the water outlet chamber 1148, and the water pressure on the side of the output port 1312 is equivalent to the pressure on the side of the reflux chamber 1146 close to the water inlet chamber 1147.

[0211] When the water pressure on the side of the input port 1311 is greater than the water pressure on the side of the output port 1312, the valve core body 1314 can open the input port 1311, so that the excess water flowing back from the water outlet chamber 1148 toward the reflux chamber 1146 can enter the fixed shell 1313 through the input port 1311, and then enter the mixing chamber 1332 from the output port 1312 after passing through the fixed shell 1313. When the water pressure on the side of the input port 1311 is less than or equal to the water pressure on the side of the output port 1312, the valve core body 1314 will reset and close the input port 1311, so that the pressure-stabilized water entering the mixing chamber 1332 cannot flow through the fixed shell 1313 and then flow back to the water outlet chamber 1148, thereby achieving the purpose of unidirectional flow control of excess water.

[0212] Preferably, please combine Fig.10 and Fig.11 As shown, the valve core body 1314 includes a movable opening and closing part 13141 and an elastic reset part 13142, wherein the elastic reset part 13142 is preferably a spring. Of course, the elastic reset part 13142 can also be selected as a component made of elastic material (such as rubber material, silicone material, etc.). The elastic reset part 13142 is preferably sleeved on the movable opening and closing part 13141, and the two ends of the elastic reset part 13142 are respectively abutted against the movable opening and closing part 13141 and the fixed shell 1313. Specifically, a spring embedding groove is provided on the movable opening and closing part 13141, and the shape and size of the spring embedding groove are adapted to the shape and size of the elastic reset part 13142. The end of the elastic reset part 13142 is embedded in the spring embedding groove to prevent the elastic reset part 13142 from deflecting during the deformation process.

[0213] In this way, when the water pressure on the side of the input port 1311 is less than or equal to the water pressure on the side of the output port 1312, the sealing head 13143 of the movable opening and closing part 13141 abuts against the sealed input port 1311, effectively preventing the pressure-stabilized water from flowing through the input port 1311. When the water pressure on the side of the input port 1311 is greater than the water pressure on the side of the output port 1312, the sealing head 13143 of the movable opening and closing part 13141 moves away from the input port 1311 under the action of pressure, and at the same time squeezes the elastic reset part 13142 to generate deformation, so that the input port 1311 is connected to the output port 1312. At this time, excess water can enter the water outlet cavity 1148 through the input port 1311. It can be understood that when the water pressure on the side of the input port 1311 is again lower than the water pressure on the side of the output port 1312, the sealing head 13143 of the movable opening and closing part 13141 will reset toward the side of the input port 1311 under the action of the deformation recovery of the elastic reset part 13142, and the sealing head 13143 will automatically abut against the sealed input port 1311, preventing the pressure-stabilized water from flowing through the input port 1311 into the water outlet chamber 1148.

[0214] To ensure the sealing between the sealing head 13143 and the input port 1311, please refer to Fig.10 and Fig.11 As shown, a first sealing groove is provided on the sealing head 13143, and the first sealing groove extends along the circumference of the sealing head 13143, and a non-return sealing ring 13144 is embedded in the first sealing groove. Under the action of the non-return sealing ring 13144, the sealing performance between the sealing head 13143 and the input port 1311 can be effectively improved, and at the same time, the sealing head 13143 of the movable opening and closing part 13141 is ensured to be in flexible contact with the fixed shell 1313 during the opening and closing process, thereby reducing the wear of the non-return body 131 during the frequent opening and closing process, thereby effectively improving the service life of the non-return body 131 and the one-way fluid guide.

[0215] Preferably, please combine Fig.10 and Fig.11 As shown, the fixed shell 1313 includes a valve seat shell 13131 and a retaining inner frame 13132, the valve seat shell 13131 is sleeved on the outer side 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 input port 1311 is arranged on the valve seat shell 13131, and the output port 1312 is arranged on the retaining inner frame 13132. When assembling the check body 131, first place the movable opening and closing part 13141 of the valve core body 1314 into the valve seat shell 13131, then sleeve the elastic reset part 13142 of the valve core body 1314 on the movable opening and closing part 13141, and finally embed the inner frame 13132 inside the valve seat shell 13131, and make the movable opening and closing part 13141 plugged into the inner frame 13132, so that the assembly of the check body 131 is completed. At this time, the sealing head 13143 of the movable opening and closing part 13141 abuts against the input port 1311 sealed on the valve seat shell 13131, and the elastic reset part 13142 is in a state of compression deformation. In this way, the valve seat shell 13131 and the inner frame 13132 can be produced separately, which reduces the difficulty of making the fixed shell 1313, thereby helping to reduce the manufacturing cost of the fixed shell 1313. At the same time, the assembly of the backstop 131 is facilitated, the assembly efficiency of the backstop 131 is improved, and the assembly cost of the backstop 131 is reduced.

[0216] Specifically, see Figure 8, a holding arm 13134 is provided on the inner holding frame 13132, and the holding arm 13134 is located on the inner side of the output port 1312, that is, a holding arm 13134 is extended from the inner holding frame 13132 toward the inner side of the output port 1312, and a guide socket 13136 for plugging the movable opening and closing part 13141 is provided on the holding arm 13134, and the shape of the guide socket 13136 can be selected to match the shape of the end of the movable opening and closing part 13141, and of course, the shape of the guide socket 13136 can also be selected to match 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 hole wall of the guide socket 13136, so that the movable opening and closing part 13141 can reciprocate along the central axis direction of the guide socket 13136, so that the guide socket 13136 cooperates with the elastic reset part 13142 to ensure that the sealing head 13143 of the movable opening and closing part 13141 is accurately reset and abutted on the input port 1311, and the end of the elastic reset part 13142 abuts against the retaining support arm 13134.

[0217] It should be noted here that Figures 8 to 11 As shown, the retaining arm 13134 is protruded toward the movable opening and closing part 13141 to provide a limiting boss 13135, and the guide plug 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 hole wall of the guide plug hole 13136. The end of the elastic reset part 13142 is sleeved on the limiting boss 13135, so that the limiting boss 13135 cooperates with the spring insertion groove provided on the movable opening and closing part 13141, which can not only ensure that the elastic reset part 13142 is firmly assembled in the fixed shell 1313, but also further prevent the elastic reset part 13142 from deflecting during the deformation process.

[0218] Further, please refer to Fig.10 As shown, in order to reduce the weight of the fixed shell 1313 and the check body 131, and also reduce the production materials of the fixed shell 1313, thereby reducing the production cost of the fixed shell 1313 and the check body 131, at least one material reduction opening 13133 is provided on the side wall of the inner frame 13132. The shape, size and number of the material reduction opening 13133 are not limited here. The shape, size and number of the material reduction opening 13133 can be set and adjusted according to the structural design and design requirements.

[0219] It should be noted that in order to ensure the sealing between the valve seat housing 13131 of the fixed housing 1313 and the inner wall of the reflux chamber 1146, please refer to the following for details. Figures 6 to 11As shown, a second sealing groove is provided on the valve seat shell 13131, and the second sealing groove extends along the circumference of the valve seat shell 13131. An outer sealing ring 137 is embedded in the second sealing groove. Under the action of the outer sealing ring 137, the sealing between the fixed shell 1313 of the check body 131 and the inner wall of the reflux chamber 1146 can be effectively improved.

[0220] It should be added here that in order to firmly install and fix the one-way flow guide 13 in the return chamber 1146 of the valve housing 11, please refer to Figure 6 and Figure 7 As shown, a pipe joint 14 is installed at the raw water outlet 1142 , and the one-way flow guide 13 is completely constrained in the reflux chamber 1146 by the pipe joint 14 , and a conduit can also be connected through the pipe joint 14 .

[0221] In addition, if Figure 3 , Figure 6 , Figure 7 As shown, at least one fastening seal ring 15 can be arranged between the pipe joint 14 and the one-way flow guide 13. On the one hand, the end of the conduit is penetrated by the fastening seal ring 15, which improves the sealing between the conduit and the reflux chamber 1146, effectively prevents the water-stabilizing water from leaking from the connection between the raw water outlet 1142 and the pipe joint 14, and also makes the conduit more firmly connected to the diverter 1. On the other hand, by utilizing the elasticity of the fastening seal ring 15, not only the pipe joint 14 and the one-way flow guide 13 are flexibly connected, but also when the pipe joint 14 is assembled to the raw water outlet 1142, the fastening seal ring 15 is elastically deformed under the extrusion of the pipe joint 14 and the one-way flow guide 13. This deformation enables the fastening seal ring 15 to fill the assembly gap between the pipe joint 14 and the one-way flow guide 13 by itself, and to adaptively change its own shape according to the size and shape of the assembly gap. At the same time, the elastic deformation also enables the fastening seal ring 15 to compensate for the gap change caused by factors such as expansion and vibration during the operation of the diverter 1 to a certain extent, thereby maintaining the stability of the assembly gap.
