[0076] The implementation, functional features and advantages of the present application will be further described with reference to the embodiments and the accompanying drawings. DETAILED DESCRIPTION

[0077] To make the purpose, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail with reference to the accompanying drawings.

[0078] The description of the following exemplary embodiments is not meant to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0079] In the description of the present application, it should be understood that the terms "first", "second" and the like are used to describe various elements, but not to imply or suggest relative importance. For those skilled in the art, the specific meaning 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, "a plurality of" means two or more, unless otherwise specified. The "and / or" describes the relationship between the associated objects, which means that there can be three relationships, for example, A and / or B can represent the three cases of A alone, A and B together, and B alone. The character " / " generally represents an "or" relationship between the associated objects.

[0080] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0081] One aspect of the present application proposes a pure drinking system, which includes a water purifier, a water tank-free 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 meets the standard of safe drinking or meets the specific use requirements. The water tank-free pipeline machine is used to instantaneously heat or cool the purified water source, so that the user can accurately obtain drinking water and meet the different drinking water temperature requirements of the user. It should be noted that the water purifier, the water tank-free pipeline machine and the faucet all belong to relatively mature existing technologies in the art, and the present application does not make significant improvements to the water purifier, the water tank-free pipeline machine and the faucet. Therefore, the structure of the water purifier, the water tank-free pipeline machine and the faucet is not described in detail, and the type and model of the water purifier and the water tank-free pipeline machine are not limited.

[0082] Considering that the water pressure in the water supply pipeline can change due to various factors (such as water supply peak, pipeline repair, etc.), a pressure reducing valve is usually configured before the water inlet of the water purifier, which not only stabilizes the water pressure in the water supply pipeline and 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 to the tankless pipeline machine and faucet at the same time and improve water utilization efficiency, a flow divider is usually configured at the rear end of the water outlet of the water purifier. The water inlet of the tankless pipeline machine and the water inlet of the faucet are connected to the flow divider. When the user needs to take temperature-adjusted drinking water, such as drinking 5℃-15℃ ice water in hot summer, or taking 40℃-50℃ warm water to wash milk powder, or taking 90℃-99℃ hot water to make tea, the user can open the tankless pipeline machine to take it. When the user needs to take domestic water to wash dishes or wash vegetables and fruits or wash clothes, the user can open the faucet to take it.

[0083] In the water purification system, the pressure reducing valve and the flow divider are independently configured, which not only occupies more space and causes the pipeline layout to be messy, increasing the installation difficulty. Moreover, when a fault occurs, the pressure reducing valve and the flow divider need to be detected and repaired separately, and replacing the pressure reducing valve and / or flow divider 1 in a limited space will greatly increase the complexity of operation and maintenance cost.

[0084] Therefore, the embodiments of the present application provide a water purification system, which also comprises a flow divider 1, the faucet, the tankless pipeline machine, the water purifier and the water supply pipeline are connected to the flow divider 1, so that the water supply pipeline can introduce tap water to the flow divider 1 and adjust the excessive and unstable water pressure of the tap water in the water supply pipeline and keep it within a preset pressure value range, finally generate stable water and deliver it to the water purifier, the water purifier will generate pure water after deep filtration and purification treatment of the stable water and flow to the flow divider 1 again, and 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 drinking water.

[0085] Specifically, please refer to Figures 1 to 5As shown, the flow divider 1 comprises a valve shell 11, which comprises a valve upper shell 116 and a valve lower shell 117 connected with each other, where the connection between the valve upper shell 116 and the valve lower shell 117 is understood as detachable connection, such as bolt connection, clamping connection, etc., so as to facilitate the production of the valve upper shell 116 and the valve lower shell 117, and effectively improve the assembly efficiency and reduce the assembly difficulty. In the embodiment, the valve upper shell 116 and the valve lower shell 117 are configured to form a water inlet cavity 1147, a backflow cavity 1146 and a water outlet cavity 1148, the water outlet cavity 1148 is in communication with the water inlet cavity 1147 through the backflow cavity 1146, the water inlet cavity 1147 and the water outlet cavity 1148 are preferably located at the top side of the backflow cavity 1146, and the valve upper shell 116 is an integrally formed component, and / or the valve lower shell 117 is an integrally formed component, so that the valve shell 11 assembled by the valve upper shell 116 and the valve lower shell 117 is more stable and has higher structural strength. In this way, when subjected to high-pressure fluid, the pressure can be evenly distributed in each part of the valve shell 11, effectively preventing the valve shell 11 from being broken. When subjected to external impact, it can better resist deformation, and compared with the combination of independent pressure reducing valve and flow divider, such flow divider 1 is less likely to loosen and separate, reducing the risk of leakage of the flow divider 1, improving the sealing performance of the flow divider 1, thereby ensuring that the sealing performance of the water purification system is more stable during long-term use, and simplifying the number of pipeline elements (such as valves, conduits, etc.) and pipeline connections of the water purification system, thereby facilitating the installation difficulty and subsequent maintenance difficulty of the water purification system. At the same time, the integrally formed technology can realize the manufacturing of the valve body through precise mold or machining process, and better control the dimensional accuracy and shape accuracy of the valve shell 11.

[0086] In the embodiment, specifically please combine Figures 1 to 4As shown, the flow distributor 1 is provided with a raw water inlet 1141, a purified water inlet 1143, a raw water outlet 1142, a first water supply outlet 1144 and a second water supply outlet 1145. The raw water inlet 1141 is used to connect a water supply pipeline to introduce tap water into the water inlet cavity 1147 of the valve housing 11, the raw water outlet 1142 is used to communicate with a water purifier to deliver the steady pressure water flowing through the water inlet cavity 1147 and treated by pressure stabilization to the water purifier, the purified water inlet 1143 is used to communicate with the water purifier to introduce purified water purified by the water purifier, the first water supply outlet 1144 is used to communicate with a tankless pipeline machine to deliver the purified water to the tankless pipeline machine, and the second water supply outlet 1145 is used to communicate with a faucet to deliver the purified water to the faucet. The raw water inlet 1141 communicates with the water inlet cavity 1147, the raw water outlet 1142 communicates with the backflow cavity 1146, and the purified water inlet 1143, the first water supply outlet 1144 and the second water supply outlet 1145 all communicate with the water outlet cavity 1148. Preferably, the raw water outlet 1142, the purified water inlet 1143 and the second water supply outlet 1145 are arranged on the lower valve body 117, and the raw water inlet 1141 and the first water supply outlet 1144 are arranged on the upper valve body 116.

[0087] Further, as shown in Figure 3 and Figure 4 The flow distributor 1 comprises a pressure regulating assembly 16 arranged in the water inlet cavity 1147 and a flow distribution assembly 17 arranged in the water outlet cavity 1148. In this way, the tap water supplied by the water supply pipeline flows into the water inlet cavity 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 troughs, maintenance and adjustment of the water supply system, etc.), for example, the water pressure is lower during the water supply peak period, and the water pressure is relatively higher during the night and other water consumption trough periods. At this time, the pressure regulating assembly 16 can reduce / pressure stabilize the tap water flowing into the water inlet cavity 1147 into steady pressure water, and then output to the water purifier for filtration and purification treatment through the raw water outlet 1142, so as to stabilize 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, purification pipeline and other precision components inside the water purifier, and improve the service life of the water purifier. In addition, the tap water passes through the filter element of the water purifier at a relatively stable flow rate, so that the filter element can fully absorb the organic matter, residual chlorine and other impurities in the tap water, so as to ensure that the water purifier always maintains the best filtration effect.

[0088] As can be understood, Figure 4As shown, the purified water is generated after the water purifier performs deep filtration and purification treatment on the steady water, and then flows into the water outlet cavity 1148 after flowing through the purified water inlet 1143 of the flow divider 1. The cooperation between the water outlet cavity 1148 and the flow dividing assembly 17 enables the purified water to flow out from the first water supply port 1144 to the water tankless pipeline machine and from the second water supply port 1145 to the faucet according to actual deployment. During the process of dividing the purified water, the excess purified water inside the water outlet cavity 1148 can flow back to the backflow cavity 1146 under the adjustment of the flow dividing assembly 17, forming excess water. The backflow cavity 1146 can combine the steady water flowing through the pressure regulating assembly 16 with the excess water flowing back from the flow dividing assembly 17, and output the steady water from the raw water outlet 1142 to the water purifier.

[0089] Next, the specific structure of the pressure regulating assembly 16 will be described in detail in combination with the drawings.

[0090] Specifically, as shown in Figure 3 , Figure 4 and Figure 5 , 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 surrounded by the valve body upper shell 116 and the pressure regulating assembly 16 forms the air cavity 1153. The pressure regulating assembly 16 is provided with a water injection guide hole 1612 and a pressure regulating water outlet 1613, both of which communicate with the liquid cavity 1611.

[0091] Further, as shown in Figure 3 , Figure 4 and Figure 5As shown, the inner wall of the chamber of the air cavity 1153 is provided with a water injection guide pipe part 1154 communicating with the raw water inlet 1141 and extending towards the inside of the air cavity 1153, and the water injection guide pipe part 1154 is inserted into the water injection flow guide hole 1612 of the pressure regulating assembly 16. Specifically, the inside of the water injection guide pipe part 1154 is provided with a water injection flow channel 1155 communicating with the raw water inlet 1141, and the water injection guide pipe part 1154 communicates with the liquid cavity 1611 through the water injection flow channel 1155, and the port for communicating with the liquid cavity 1611 of the water injection flow channel 1155 is a water passing port. The valve housing 11 is provided with a pressure relief cavity discharge port 1151, so that the liquid cavity 1611 can communicate with the backflow cavity 1146 through the pressure relief cavity discharge port 1151, and then the water pressure on the side of the liquid cavity 1611 close to the pressure regulating water outlet 1613 is equal to the water pressure in the backflow cavity 1146, that is, the outlet pressure on the side of the pressure regulating water outlet 1613 of the pressure regulating assembly 16 is equivalent to the water pressure of the stable pressure water supplied to the water purifier, and the water pressure on the side of the liquid cavity 1611 close to the water injection flow guide hole 1612 is equal to the water pressure of the water supply pipeline, that is, the inlet pressure on the side of the water injection flow 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 in the inside of the liquid cavity 1611. In this way, when a pressure difference is formed between the pressure regulating water outlet 1613 and the water injection flow guide hole 1612, the pressure regulating assembly 16 can produce a relative displacement along the central axis of the water injection guide pipe part 1154 to change the throttling distance between the water passing port and the pressure regulating execution end.

[0092] As can be understood, 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 flow channel 1155 from the raw water inlet 1141, it will flow through the water passing port, the water injection flow guide hole 1612, the pressure regulating water outlet 1613, and the pressure relief cavity discharge port 1151 in turn and flow to the backflow cavity 1146. When the outlet pressure of the pressure regulating assembly 16 rises (such as when the water purifier is turned off), the pressure on the side of the pressure regulating water outlet 1613 will drive the pressure regulating assembly 16 to produce a displacement along the central axis of the water injection guide pipe part 1154 and towards the side close to the water passing port, and then the pressure regulating execution end of the pressure regulating assembly 16 moves towards the water passing port, so that the throttling distance between the water passing port and the pressure regulating execution end decreases, that is, the flow area between the water passing port and the pressure regulating execution end through which the tap water can pass decreases, until the force balance position is reached. When the outlet pressure decreases (such as when the water purifier is turned on), the pressure on the side of the water injection flow guide hole 1612 will drive the pressure regulating assembly 16 to produce a displacement along the central axis of the water injection guide pipe part 1154 and towards the side away from the water passing port, and then the pressure regulating execution end of the pressure regulating assembly 16 moves away from the water passing port, so that the throttling distance between the water passing port and the pressure regulating execution end increases, until the pressure regulating execution end returns to the force balance state.

[0093] Therefore, as the outlet pressure changes, the pressure regulating assembly 16 automatically makes corresponding displacement to change the throttling distance between the water passage port and the pressure regulating execution end, so as to achieve the purpose of pressure stabilization, 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 of maintenance personnel. In addition, since the water injection guide pipe part 1154 is inserted into the water injection flow guide hole 1612 of the pressure regulating assembly 16, not only does it make the pressure regulating assembly 16 more stable during displacement, but it also ensures that the pressure regulating execution end moves precisely towards or away from the water passage port, thereby precisely adjusting the throttling distance between the water passage port and the pressure regulating execution end, achieving the purpose of precise pressure regulation. During the assembly of the pressure regulating assembly 16 to the valve shell 11, the water injection guide pipe part 1154 can also position the pressure regulating assembly 16, achieving the purpose of improving assembly efficiency and positioning accuracy.

[0094] The unexpected effect is that, as shown in Figure 3 and Figure 5 , the tap water flowing from the raw water inlet 1141 flows into the liquid cavity 1611 under the guidance of the water injection flow channel 1155, and does not fill the entire water inlet cavity 1147, which not only makes the pressure regulation response more timely and accurate. At the same time, it can further reduce the probability of leakage of tap water from the assembly position between the pressure regulating assembly 16 and the valve shell 11, thereby improving the structural stability and reliability of the flow divider 1.

[0095] As shown in Figure 3 , the pressure regulating assembly 16 includes a valve core assembly 162 and a pressure regulating elastic member 163 with elasticity, i.e. the pressure regulating elastic member 163 is made of a material that can elastically deform (such as silicone, rubber, etc.), the water injection flow guide hole 1612 and the pressure regulating water outlet 1613 are arranged on the valve core assembly 162, and the valve core assembly 162 is detachably connected with the pressure regulating elastic member 163, so as to facilitate disassembly and assembly of the valve core assembly 162 and the pressure regulating elastic member 163. When the pressure regulating elastic member 163 is damaged or loses elasticity after long-term use, the pressure regulating elastic member 163 can be replaced individually, reducing the maintenance cost of the pressure regulating assembly 16. As shown in Figure 4 , 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 flow guide hole 1612, the pressure regulating elastic member 163 can deform, and the valve core assembly 162 slides relatively along the extension direction of the water injection guide pipe part 1154.

[0096] It can be understood that when the outlet pressure on the side of the pressure regulating outlet 1613 of the valve core assembly 162 rises, the pressure regulating elastic member 163 is elastically deformed towards the side close to the water passage port under the action of the outlet pressure, and at the same time, the valve core assembly 162 also moves along the central axis of the water injection guide pipe part 1154 and towards the side close to the water passage port. When the inlet pressure on the side of the water injection flow guide hole 1612 of the valve core assembly 162 decreases, the pressure regulating elastic member 163 is reset towards the side away from the water passage port under the action of the outlet pressure and the deformation recovery of the pressure regulating elastic member 163, and at the same time, the valve core assembly 162 also moves along the central axis of the water injection guide pipe part 1154 and towards the side away from the water passage port.

[0097] As a preferred mode of the present embodiment, as shown in Figure 5 , 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 flow guide hole 16121, and the valve core base 1622 is provided with a second flow guide hole 16122, the first flow guide hole 16121 and the second flow guide hole 16122 constitute the water injection flow guide hole 1612, the central axis of the first flow guide hole 16121 is collinear with the central axis of the second flow guide hole 16122, ensuring that the water injection guide pipe part 1154 can be sequentially inserted into the first flow guide hole 16121 and the second flow guide hole 16122, and the pressure regulating outlet 1613 is arranged on the valve core base 1622. Further, as shown in Figure 12 and Figure 13 , the valve core limiting sleeve 1621 is sleeved outside the valve core base 1622, and part of the pressure regulating elastic member 163 is clamped 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 segment 1625, and the valve core limiting sleeve 1621 is provided with an internal thread segment 1626 threadedly connected with the external thread segment 1625, so that the valve core limiting sleeve 1621 and the valve core base 1622 are screw-fixed, which not only realizes the detachable connection of the valve core assembly 162 and the pressure regulating elastic member 163, but also makes the assembly more convenient and efficient.

[0098] Specifically, as shown in Figure 5 , the inner diameter of the port of the valve core limiting sleeve 1621 close to one end of the pressure regulating elastic member 163 is greater than the diameter of the valve core base 1622, so that a clamping space is formed between the valve core limiting sleeve 1621 close to one end of the pressure regulating elastic member 163 and the outer side wall of the valve core base 1622. Further, in combination with Figure 12 , Figure 13 and Figure 14As shown, the pressure regulating elastic member 163 comprises an elastic member body 1631 and a clamping protrusion 1632 extending from the elastic member body 1631 towards 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 is formed into an elastic sleeve hole 164 together with the clamping protrusion 1632, 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 limiting sleeve 1621 and the valve core base 1622. In this way, the valve core limiting sleeve 1621 and the valve core base 1622 cooperate to clamp the pressure regulating elastic member 163, so that the connection between the pressure regulating elastic member 163 and the valve core assembly 162 is more stable, thereby ensuring that the pressure regulating elastic member 163 and the valve core assembly 162 do not separate during the elastic deformation of the pressure regulating elastic member 163 and the movement of the valve core assembly 162, and improving the stability of the pressure regulating assembly 16 during the working process.

[0099] Further, please refer to the specific embodiment according to Figure 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 frictional resistance between the clamping protrusion 1632 and the valve core limiting sleeve 1621, and effectively preventing the clamping protrusion 1632 from separating 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 is integrally formed with the second fastening protrusion 16332, which can also increase the frictional resistance between the clamping protrusion 1632 and the valve core limiting sleeve 1621.

[0100] Further, please refer to the specific embodiment according to Figure 14 As shown, the clamping protrusion 1632 is further provided with a third fastening protrusion 16333, and 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 frictional resistance between the clamping protrusion 1632 and the valve core base 1622, and further preventing the clamping protrusion 1632 from separating from the clamping space. Of course, the third fastening protrusion 16333 can also be provided on the valve core base 1622, and the valve core base 1622 is integrally formed with the third fastening protrusion 16333, which can also increase the frictional resistance between the clamping protrusion 1632 and the valve core base 1622.

[0101] It should be noted that the second fastening protrusion 16332 can be combined with the third fastening protrusion 16333, which not only better prevents the clamping protrusion 1632 from being separated from the clamping space, but also enables the clamping protrusion 1632 to be more compactly assembled in the clamping space.

[0102] In addition, according to the specific Figure 5 As shown in the figure, the pressure regulating assembly 16 further comprises a valve core sealing ring 165, and the valve core limiting sleeve 1621 and the valve core base 1622 cooperate to form a valve core sealing cavity. The valve core sealing ring 165 is sleeved on the water injection guide pipe portion 1154 and embedded in the valve core sealing cavity, so as to better prevent tap water from seeping out from between the water injection guide hole 1612 and the water injection guide pipe portion 1154 into the air cavity 1153.

[0103] In this embodiment, in order to ensure that the pressure regulating elastic member 163 can be more quickly and stably connected between the valve body upper shell 116 and the valve body lower shell 117, the inventor provides a preferred mode, which is specifically combined with Figures 1 to 5 As shown in the figure, the above-mentioned elastic member body 1631 is clamped between the valve body upper shell 116 and the valve body lower shell 117. Specifically, according to Figure 14 As shown in the figure, the valve body lower shell 117 is provided with a shell clamping groove extending along the circumference of the valve body lower shell 117. The pressure regulating elastic member 163 is extended into a sealing buckle portion 1635 towards the inside of the shell clamping groove, and the sealing buckle portion 1635 extends along the groove length direction of the shell clamping groove and is inserted into the shell clamping groove. In this way, the pressure regulating elastic member 163 can be more compactly and stably clamped on the valve shell 11, so that the pressure regulating assembly 16 is more stably installed on the valve shell 11 under the premise of facilitating the assembly of the pressure regulating assembly 16. At the same time, the sealing property of the connection position between the pressure regulating elastic member 163 and the valve shell 11 is ensured, which prevents water from seeping out of the valve shell 11 and avoids the problem of rusting and failure of the components in the air cavity 1153 caused by the penetration of water into the air cavity 1153. It should be noted that the shell clamping groove can also be provided on the valve body upper shell 116, or both the valve body upper shell 116 and the valve body lower shell 117 can be provided with the shell clamping groove, which can be set and adjusted according to the structure design and design requirements.

[0104] Further, according to the specific Figure 14As shown, the first fastening protrusion 16331 is arranged on the sealing buckle 1635 and is integrally formed with the sealing buckle 1635, so that the first fastening protrusion 16331 is clamped between the sealing buckle 1635 and the shell clamping groove, thereby increasing the frictional resistance between the sealing buckle 1635 and the shell clamping groove, so that the sealing buckle 1635 is more stably inserted into the shell clamping groove and better prevents the sealing buckle 1635 from being separated from the shell clamping groove. Of course, the first fastening protrusion 16331 can also be arranged on the groove wall of the shell clamping groove, which can also increase the frictional resistance between the sealing buckle 1635 and the shell clamping groove.

[0105] As a preferred mode of the present embodiment, please refer to Figure 14 As shown, the elastic member body 1631 is provided with a deformation adjusting groove 1634, which is in a U-shaped structure, and the groove opening of the deformation adjusting groove 1634 is preferably directed to the air cavity 1153. As shown in Figure 5 As shown, the deformation adjusting groove 1634 is curved and formed at the part of the elastic member body 1631 between the valve core base 1622 and the valve shell 11, and the deformation adjusting groove 1634 extends along the circumference of the valve core base 1622. This not only provides sufficient space for the elastic member body 1631 to deform elastically, but also provides a larger elastic deformation range in a limited space, thereby increasing the elastic ability of the pressure regulating elastic member 163.

[0106] As a preferred mode of the present embodiment, please refer to Figure 12 As shown, the valve core base 1622 comprises a valve flap plug 1623, which is the pressure regulating execution end of the pressure regulating assembly 16. As shown in Figure 13 As shown, the valve flap plug 1623 is provided with a valve flap support beam 1624 extending towards 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 with 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, the valve flap support beam 1624 extends along the circumference of the valve flap plug 1623, and a plurality of water flow through holes are uniformly arranged on the valve flap support beam 1624 along the circumference of the valve flap plug 1623, so that the pressure regulating water can flow through the water flow through holes. Alternatively, the valve flap support beam 1624 is preferably a plurality of valve flap support beams 1624, which are uniformly distributed on the circumferential side of the valve flap plug 1623, and adjacent two valve flap support beams 1624 are arranged at intervals, so that the pressure regulating water can flow from the circumferential side of the valve flap plug 1623.

[0107] To avoid rigid contact between the valve plug 1623 and the water inlet of the water inlet pipe 1154, and to reduce the noise of the distributor 1, please refer to the following for details. Figure 5 , Figure 12 and Figure 13 As shown, the valve disc plug 1623 includes a valve disc support 16231 and an elastic plug element 16232. The elastic plug element 16232 can be made of silicone. The valve disc support 16231 is provided with a valve disc insertion groove 16233 for embedding the elastic plug element 16232. The valve disc support 16231 is fixedly connected to the body of the valve core base 1622 through the valve disc support beam 1624.

[0108] In this embodiment, please refer to the details. 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. One end of the pressure regulating spring 166 abuts against the inner wall of the air cavity 1153, and the other end of the pressure regulating spring 166 abuts against the valve core assembly 162. When a pressure difference is formed between the pressure regulating outlet 1613 and the water injection guide hole 1612, both the pressure regulating elastic element 163 and the pressure regulating spring 166 will deform.

[0109] On the one hand, during pressure regulation, the pressure regulating spring 166 can assist the pressure regulating elastic element 163 in returning to its initial or equilibrium position after pressure changes. That is, the pressure regulating spring 166 can use its own elastic force to push the pressure regulating elastic element 163 back to a certain position, causing the valve core assembly 162 to move accordingly and return to a state close to its original state, thereby ensuring the stability of the outlet pressure. Moreover, the elastic coefficient of the pressure regulating spring 166 is relatively stable, which helps to more accurately control the deformation of the pressure regulating elastic element 163, thereby precisely controlling the outlet pressure. On the other hand, the pressure regulating spring 166 can, to a certain extent, share the pressure borne by the pressure regulating elastic element 163, thus avoiding the problem that the pressure regulating elastic element 163 might suffer excessive deformation, fatigue failure, or even damage if it bears the pressure alone when the inlet pressure is too high or when there are frequent starts and stops.

[0110] Furthermore, the combination of the pressure regulating spring 166 and the pressure regulating elastic element 163 allows the valve core assembly 162 to respond more quickly to pressure changes. When the pressure changes, the elastic force of the pressure regulating spring 166 and the deformation force of the pressure regulating elastic element 163 work together to accelerate the movement of the valve core assembly 162, that is, to quickly adjust the throttling distance between the water inlet and the pressure regulating actuator, thereby improving the pressure regulating efficiency of the diverter 1.

[0111] Furthermore, please refer to the specific details. Figures 3 to 5As shown, the inner wall of the chamber of the air cavity 1153 is provided with a pressure regulating limiting platform 1194 along the extension direction of the water injection conduit portion 1154, the length of the extension of the pressure regulating limiting platform 1194 is smaller than the length of the extension of the water injection conduit portion 1154, the end of the pressure regulating spring 166 is sleeved outside the pressure regulating limiting platform 1194, so as to limit the pressure regulating spring 166 and improve the positioning accuracy and assembly efficiency of the pressure regulating spring 166 during assembly.

[0112] Preferably, in particular, please combine Figures 3 to 5 As shown, the valve core assembly 162 can abut against the pressure regulating limiting platform 1194 along the central axis of the water injection conduit portion 1154, so that the pressure regulating execution end seals 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 towards the side close to the water passing port, the valve core limiting sleeve 1621 of the valve core assembly 162 abuts against the pressure regulating limiting platform 1194, and the plug elastic element 16232 of the valve core assembly 162 will also abut against the water passing port of the water injection conduit portion 1154, thereby improving the bearing area and bearing force of the flow divider 1.

[0113] Further, in particular, please combine Figure 3 As shown, the valve housing 11 is also provided with a breathing hole 118, and the air cavity 1153 is communicated with 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. As can be understood, when the pressure regulating elastic element 163 and the pressure regulating spring 166 are deformed, the space pressure inside the air cavity 1153 will change. At this time, the air cavity 1153 is communicated with the atmospheric pressure through the breathing hole 118, which helps to keep the pressure of the air cavity 1153 where the pressure regulating spring 166 is stable, thereby avoiding the risk of excessive deformation and rupture of the pressure regulating elastic element 163 due to the pressure difference on both sides of the pressure regulating elastic element 163 exceeding the bearing capacity of the pressure regulating elastic element 163, thereby improving the service life of the pressure regulating assembly 16 and the flow divider 1. In addition, the pressure in the air cavity 1153 is communicated with the external environment pressure through the breathing hole 118, which can well avoid the cavitation phenomenon caused by the pressure being reduced below the saturated vapor pressure of tap water during the pressure reduction / regulation of tap water, thereby avoiding the problems of vibration and noise of the flow divider 1 due to the existence of bubbles.

[0114] Preferably, in particular, please combine Figure 3As shown, the breathing hole 118 is arranged on the valve body upper shell 116 of the valve shell 11, and the central axis of the breathing hole 118 is arranged in parallel with the central axis of the water injection guide pipe part 1154. In this way, from the aspect of stability, the consistent direction helps to maintain the balance state of the air cavity 1153. During the 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, which cooperates with the action of the pressure regulating spring 166 and the pressure regulating elastic member 163 to quickly adjust the internal pressure. From the aspect of the accuracy of pressure regulation, when the breathing hole 118 is consistent with the extension direction of the pressure regulating spring 166, the path of the gas entering and exiting the breathing hole 118 is more matched and coordinated with the internal space change path caused by the extension of the pressure regulating spring 166 during the pressure change, which will be able to more accurately control the reduction range of the pressure.

[0115] Further, please refer to the specific description of Figure 3 As shown, the breathing hole 118 is arranged on the valve body upper shell 116 near the edge, and the breathing hole 118 extends along the extension direction of the water injection guide pipe part 1154 to the side of the valve body upper shell 116 near 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, effectively avoiding the unstable phenomenon of local turbulent flow of the gas, thereby ensuring that the air cavity 1153 can more accurately perceive the change of the pressure and more accurately regulate the pressure, and improving the accuracy of pressure regulation. Of course, the flat inner hole wall is also not easy to accumulate impurities. In some working environments, the fluid may carry small particle impurities, which are easy to accumulate at the protrusions, and over time, may cause the breathing hole 118 to be blocked. The flat inner hole wall makes it not easy 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 further ensure the stable operation of the entire flow divider 1.

[0116] As a preferred mode of the present embodiment, please refer to the specific description of Figure 6 and Figure 7As shown, the valve body lower shell 117 of the valve shell 11 is provided with a limiting support column 1191, which is preferably located directly below the valve flap plug 1623 and protrudes towards the liquid cavity 1611. The pressure regulating execution end of the pressure regulating assembly 16 can abut against the limiting support column 1191, so that the shunt 1 can limit the pressure regulating execution end of the valve core assembly 162 in the non-use state or when the outlet pressure drops, that is, the limiting 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 passage port of the water injection flow channel 1155 is maximum. Further, the end of the limiting support column 1191 near the pressure regulating execution end is provided with an anti-sticking protrusion 1192, so that the limiting support column 1191 and the pressure regulating execution end form a gap. This is equivalent to reducing the contact area between the limiting 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 limiting support column 1191, so that when the end of the limiting support column 1191 is fouled, the pressure regulating execution end will not be stuck to the limiting support column 1191, effectively preventing the shunt 1 from failing to regulate pressure.

[0117] Further, as shown in Figure 6 and Figure 7 As shown, the anti-sticking protrusions 1192 are distributed at the edge positions of the end of the limiting support column 1191 and extend along the circumference of the limiting support column 1191. The anti-sticking protrusions 1192 are preferably arc-shaped structures formed along the circumference of the limiting support column 1191. When tap water flows through the limiting support column 1191, it can clean the end of the limiting support column 1191, reducing the probability of fouling at the end of the limiting support column 1191.

[0118] It should be noted that the anti-sticking protrusions 1192 can also be provided on the pressure regulating execution end, that is, the anti-sticking protrusions 1192 are provided on the valve flap support 16231 of the valve flap plug 1623.

[0119] Preferably, the end of the limiting support column 1191 can also be provided with a groove 1193, and the anti-sticking protrusions 1192 are located at the side of the groove 1193. In this way, the gap distance between the limiting support column 1191 and the pressure regulating execution end is effectively increased, thereby further preventing the pressure regulating execution end from sticking to the limiting support column 1191 and improving the stability of the pressure regulation of the shunt 1.

[0120] Further, as shown in Figure 15As shown, the valve seat 16231 is provided with at least one through hole 16234 near one side wall of the limiting support column 1191, which not only facilitates the embedding and pushing out of the plug elastic member 16232 in / from the valve seat embedding groove 16233 of the valve seat 16231, but also further reduces the contact area of the pressure regulating execution end.

[0121] In the above, the water outlet cavity 1148 cooperates with the shunt assembly 17 to distribute the purified water purified by the water purifier, and the excess purified water inside the water outlet cavity 1148 can flow back to the backflow cavity 1146 under the adjustment of the shunt assembly 17, forming excess water, thereby effectively preventing the water purifier from frequently starting and stopping due to the large fluctuation range of water pressure during the process of suddenly starting the water tankless pipeline machine and / or faucet.

[0122] Next, the specific structure of the shunt assembly 17 will be described in detail in combination with the drawings.

[0123] The shunt assembly 17 is provided with a flow hole for guiding the purified water flowing from the purified water inlet 1143 to pass through the shunt assembly 17 and enter the water outlet cavity 1148. Further, please refer to Figure 17 , the shunt assembly 17 divides the water outlet cavity 1148 into a water outlet lower cavity 11481 and a water outlet upper cavity 11482. The above-mentioned purified water inlet 1143 and the second water supply port 1145 are both communicated with the water outlet lower cavity 11481, the water outlet upper cavity 11482 is communicated with the first water supply port 1144, and the water outlet upper cavity 11482 is communicated with the water outlet lower cavity 11481 through the flow hole. At this time, the purified water flowing from the purified water inlet 1143 into the water outlet lower cavity 11481 for buffering and storage, and a part of it will flow to the water outlet upper cavity 11482 through the flow hole, and finally flow out from the first water supply port 1144.

[0124] In addition, as shown in Figure 24As shown, the valve housing 11 has a backflow guide portion 1171 inside the water outlet cavity 1148, and the inside of the backflow guide portion 1171 is provided with a guide flow channel 1172 communicating with the backflow cavity 1146. Specifically, the backflow guide portion 1171 is arranged on the valve body lower shell 117 and extends towards the inside of the water outlet cavity 1148, wherein the guide flow channel 1172 extends in the port of the water outlet lower cavity 11481 and communicates with the water outlet lower cavity 11481. The shunt assembly 17 can abut against the backflow 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 shunt assembly 17 can produce relative displacement towards the first water supply port 1144 side, so that the shunt assembly 17 is separated from the backflow guide portion 1171, and then the excessive pure water can flow from the guide flow channel 1172 into the backflow cavity 1146 to form the above-mentioned excess water.

[0125] In this way, when the faucet is used alone, the pure water will flow from the pure water inlet 1143 into the water outlet lower cavity 11481, and then directly flow out from the second water supply port 1145. At this time, the shunt assembly 17 abuts and fits on the backflow guide portion 1171 to seal the guide flow channel 1172, so that the pure water will not flow back to the guide flow channel 1172.

[0126] When the tankless pipeline machine is used alone, the pure water flows from the pure water inlet 1143 into the water outlet lower cavity 11481, and then flows through the flow hole into the water outlet upper cavity 11482, and finally flows out from the first water supply port 1144 to the tankless pipeline machine. At this time, the pressure on the side of the shunt assembly 17 close to the first water supply port 1144 is less than the pressure on the side of the shunt assembly 17 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 shunt assembly 17 can produce relative displacement towards the first water supply port 1144 side, so that the shunt assembly 17 is separated from the backflow guide portion 1171, and the excessive pure water flows back to the guide flow channel 1172. Understandably, the water outlet amount of the first water supply port 1144 is determined according to the water pump and negative pressure valve of the tankless pipeline machine.

[0127] When the tankless pipeline machine is closed, the shunt assembly 17 will reset towards the side of the backflow guide portion 1171, so that the shunt assembly 17 abuts on the backflow guide portion 1171 again to reseal the guide flow channel 1172. Therefore, the shunt 1 can flexibly meet the water flow distribution demand when the tankless pipeline machine is used alone, so that the pure water can meet the water demand of the tankless pipeline machine while reasonably processing the excess water, without wasting water resources and avoiding the risk of damaging the tankless pipeline machine due to excessive water pressure.

[0128] When the water tankless pipeline machine and the faucet are used simultaneously, the purified water flows into the water outlet lower cavity 11481 from the purified water inlet 1143, and part of the purified water flows out from the second water supply port 1145 to the faucet, and the other part of the purified water enters the water outlet upper cavity 11482 through the overflow hole and flows out from the first water supply port 1144 to the water tankless pipeline machine. Because the water pressure on the side of the second water supply port 1145 is reduced, the pressure on the side of the first water supply port 1144 of the flow splitting component 17 and the pressure on the side of the first water supply port 1144 of the flow splitting component 17 are not much different, at this time, the flow splitting component 17 abuts and fits on the backflow guide portion 1171, and then the excess purified water almost does not flow to the guide flow channel 1172. In this way, the water tankless pipeline machine and the faucet can be normally used, and the stable operation of the entire purified drinking system is ensured.

[0129] Therefore, because the excess purified water can backflow when only the water tankless pipeline machine is enabled, the purified water machine can avoid frequent adjustment of its working state due to sudden changes in the water consumption of the water tankless pipeline machine (such as water pressure changes caused by frequent opening and closing of the water tankless pipeline machine). For example, if there is no backflow mechanism, when the water tankless pipeline machine is suddenly closed, the instantaneous change in water pressure can cause an impact on the internal structure and working pressure of the purified water machine, and with the backflow mechanism, the water pressure change can be buffered to a certain extent, and the pressure of the purified water machine caused by frequent start and stop can be reduced. In the case of simultaneous use, the relative stable water flow distribution state is maintained by the action of the flow splitting component 17. If there is no flow splitting component 17, and the faucet and the water tankless pipeline machine are working simultaneously, a sudden change in water consumption (such as sudden closing of the faucet) can cause a large fluctuation in the internal water pressure of the purified water machine, resulting in frequent adjustment of the working state of the purified water machine. The flow splitting component 17 can maintain a relatively stable water pressure and water flow distribution, and reduce the situation of frequent start and stop of the purified water machine caused by changes in the external water consumption.

[0130] In the related art, the overflow hole can elastically stretch and contract, and the flow of the purified water through the overflow hole is adjusted by the slight deformation of the overflow hole. That is, when the water consumption of the water tankless pipeline machine increases, the overflow hole increases with the increase of the pressure difference between the two sides of the flow splitting component 17, and the flow of the purified water increases. When the water consumption of the water tankless pipeline machine decreases, the overflow hole shrinks under the action of its own elastic force, and the flow of the purified water decreases, so as to automatically maintain the pressure difference between the two sides of the flow splitting component 17 and delay the reset of the flow splitting component 17. However, because the deformation amount of the overflow hole is limited, that is, the maximum and minimum flow range that it can adjust is also greatly limited. For example, when the water consumption of the water terminal changes in a large range, due to the limitation of the size and deformation amount of the overflow hole, only the overflow hole with a small deformation amount cannot meet the actual flow adjustment requirement.

[0131] Therefore, the embodiment of the present application provides a shunt assembly 17, which aims to solve the problem that the maximum and minimum flow range that can be adjusted is limited due to the deformation of the overflow hole in the prior art.

[0132] Specifically, as shown in Figure 16 The shunt assembly 17 is provided with a flexible check portion 1721 provided with a flow adjusting opening 1722. The flexible check portion 1721 can control the opening size of the flow adjusting opening 1722 according to the pressure difference formed by the pure water inlet 1143, the first water supply opening 1144 and the second water supply opening 1145, so as to adjust the increase variable of the pure water flowing into the water outlet cavity 1148. The increase variable herein should be understood as a physical quantity that the volume flow of the pure water increases with the change of the opening size of the flow adjusting opening 1722 during the flow through the flow adjusting opening 1722. That is, the flexible check portion 1721 has elasticity. When the water outlet amount of the first water supply opening 1144 is large, the pressure difference formed by the pure water inlet 1143, the first water supply opening 1144 and the second water supply opening 1145 is large, the flow adjusting opening 1722 of the flexible check portion 1721 can be opened, then the water outlet upper cavity 11482 will also be connected to the water outlet lower cavity 11481 through the flow adjusting opening 1722, and the cross-sectional area of the flow adjusting opening 1722 will increase with the increase of the pressure difference, until the flow adjusting opening 1722 is opened to the maximum deformation state, then the opening size of the flow adjusting opening 1722 will change from zero to the maximum, so that the volume flow of the pure water passing through the flow adjusting opening 1722 (hereinafter referred to as flow) can increase from zero to the maximum, so that part of the pure water will also be supplemented into the water outlet upper cavity 11482 through the flow adjusting opening 1722. It can be understood that when the pressure difference decreases, the flow adjusting opening 1722 will automatically decrease under the deformation recovery, until it is completely closed, at this time, the pure water will hardly flow through the flow adjusting opening 1722.

[0133] Therefore, when the water consumption range of the water terminal changes greatly, the increase variable of the pure water flowing into the water outlet cavity 1148 can be changed through the elastic deformation of the flexible check portion 1721, thereby solving the problem that the maximum and minimum flow range that can be adjusted is limited due to the deformation of the overflow hole in the prior art. Moreover, once the opening degree of the flow adjusting opening 1722 is adjusted, the flow of the pure water is relatively stable. Compared with only providing an overflow hole that can be stretched and contracted, the risk of being blocked can be reduced during long-term use, thereby better ensuring the use stability of the shunt assembly 17 and the shunt 1, and reducing the cost of processing and manufacturing and the cost of later maintenance.

[0134] It should be noted that the above-mentioned overflow hole capable of elastic stretching and contraction cooperates with the flexible check portion 1721, that is, the overflow hole and the flexible check portion 1721 are provided on the shunt assembly 17 at the same time.

[0135] Next, the specific structure of the above-mentioned shunt component 17 will be described in detail with reference to the accompanying drawings.

[0136] Please refer to the specific details. Figure 24 As shown, the diversion assembly 17 includes a diversion balancing diaphragm 172 and a balancing spring 171. The diversion balancing diaphragm 172 is detachably connected between the upper valve body shell 116 and the lower valve body shell 117. The upper valve body shell 116 and the diversion balancing diaphragm 172 cooperate to form an upper outlet chamber 11482, and the lower valve body shell 117 and the diversion balancing diaphragm 172 cooperate to form a lower outlet chamber 11481. The balancing spring 171 is disposed between the diversion balancing diaphragm 172 and the inner wall of the upper outlet chamber 11482.

[0137] Please see below. Figures 17 to 21 The diversion balancing membrane 172 is made of an elastic material (such as silicone or rubber). The diversion balancing membrane 172 has diaphragm through-holes 1724, which are also diaphragm through-holes, allowing for elastic expansion and contraction. Furthermore, the flexible check valve 1721 is provided on the diversion balancing membrane 172. The flexible check valve 1721, in conjunction with the through-holes, enables more precise flow control. When the demand for pure water is low, a small pressure difference may cause the through-holes to deform, finely regulating the flow and improving the adjustment accuracy of the diversion component 17 and the diverter 1. When the demand for pure water is high, the flexible check valve 1721 can deform under a large pressure difference, allowing a large amount of pure water to pass through. This combination is equivalent to a multi-stage regulation system, capable of precisely adjusting the flow through the diverter 1 according to different operating conditions (such as different water usage rates in tankless water dispensers), and effectively reducing the probability of frequent start-ups and shutdowns of the water purifier. Meanwhile, through the synergistic effect of the flow-through holes on the flow-balancing membrane 172 and the flexible check valve 1721, the pressure balance on both sides of the flow-dividing assembly 17 can be better maintained. That is, they can flexibly adjust their own state according to the magnitude of the pressure difference on both sides, making the distribution of pure water in the outlet chamber 1148 more stable, which helps to improve the reliability and service life of the flow divider 1 and reduce the damage to its components and system failures caused by pressure imbalance.

[0138] Thus, when the water consumption of the pipeline machine without a water tank is large, the pressure on the side of the shunt balance membrane 172 close to the first water inlet 1144 is significantly different from the pressure on the side of the shunt assembly 17 away from the first water inlet 1144. The shunt balance membrane 172 will elastically deform towards the side of the first water inlet 1144 and compress the balance spring 171. When the water consumption of the pipeline machine without a water tank decreases, the pressure difference between the two sides of the shunt balance membrane 172 decreases, and the first water inlet 1144 has almost no pure water flow, meaning that there is no corresponding pressure due to the flow of pure water. At this time, the state of the two sides of the shunt balance membrane 172 returns to the initial balanced state. Under the action of the elastic deformation of the shunt balance membrane 172 itself and the elastic deformation of the balance spring 171, the side of the shunt balance membrane 172 away from the first water inlet 1144 deforms and recovers until the shunt balance membrane 172 abuts against the flexible check portion 1721 to seal the guide flow channel 1172. Such a design has the following unexpected effects:

[0139] 1. When the water consumption of the pipeline machine without a water tank is large, the pressure on the side of the shunt balance membrane 172 close to the first water inlet 1144 is significantly different from the pressure on the side of the shunt assembly 17 away from the first water inlet 1144. The shunt balance membrane 172 will elastically deform towards the side of the first water inlet 1144 and compress the balance spring 171. At this time, the balance spring 171 acts as a buffer to absorb part of the pressure, preventing the shunt balance membrane 172 from being damaged due to excessive instantaneous pressure. When the water consumption of the pipeline machine without a water tank decreases, the pressure difference between the two sides of the shunt balance membrane 172 decreases. Since the balance spring 171 stores elastic potential energy after being compressed, the balance spring 171 releases the elastic potential energy to help the side of the shunt balance membrane 172 away from the first water inlet 1144 deform and recover.

[0140] 2. The elastic properties of the shunt balance membrane 172 can automatically adjust the size of the overflow hole according to the change in 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 device 1. For example, when the pressure difference changes slightly, the slight deformation of the shunt balance membrane 172 and the slight expansion of the balance spring 171 work together to more accurately regulate the amount of pure water flowing, thereby better achieving the function of automatically maintaining the pressure difference between the two sides of the shunt balance membrane 172.

[0141] 3. During the entire use of the tankless water dispenser, the water consumption is dynamically changing. The balance spring 171 and the diversion balance membrane 172 work together to effectively regulate the internal pressure balance of the water dispenser under different water usage conditions. This cooperation allows the diverter 1 to adapt to complex and changing operating conditions, reducing system failures caused by factors such as sudden pressure changes, enhancing the stability and reliability of the system, and extending the service life of the diverter 1. Furthermore, when the water consumption of the tankless water dispenser changes rapidly, the synergistic effect of the balance spring 171 and the diversion balance membrane 172 allows the diverter 1 to respond quickly. For example, when the water consumption of the tankless water dispenser suddenly increases, the balance spring 171 can quickly buffer the deformation of the diversion balance membrane 172, causing the flexible check valve 1721 to expand rapidly and increase the water flow. Conversely, when the water consumption of the tankless water dispenser suddenly decreases, both mechanisms can promptly reset the diversion balance membrane 172, reducing the flow of purified water, thereby optimizing the dynamic response capability of the diversion process.

[0142] It should be further explained that, please refer to the specific details. Figure 21 As shown, the aforementioned flexible check valve 1721 has a duckbill-shaped structure. A duckbill cavity 1723 is provided inside the flexible check valve 1721. The duckbill cavity 1723 passes through the diversion balancing membrane 172, and a duckbill opening is formed on the side of the diversion balancing membrane 172 facing away from the flexible check valve 1721. For details, please refer to... Figures 17 to 21 The flexible check valve 1721 includes a duckbill-shaped deformation portion 17211 and a base 17212 fixedly connected to the diversion balancing membrane 172. The duckbill-shaped deformation portion 17211, the base 17212, and the diversion balancing membrane 172 are integrally formed to facilitate processing and manufacturing, and also to ensure the integrity of the diversion balancing membrane 172, so that the diversion balancing membrane 172 has good comprehensive properties (such as elasticity). The duckbill-shaped deformation portion 17211 extends from the base 1721. 2. The upper cavity 11482 of the water outlet is convex, and the cross-sectional area of ​​the duckbill deformation part 17211 gradually decreases along the convex direction. The cross-section here is parallel to the large surface of the diversion balance membrane 172. The large surface of the diversion balance membrane 172 is the side with the largest area in the diversion balance membrane 172. The flow regulating port 1722 is located at the end of the duckbill deformation part 17211 away from the diversion balance membrane 172, and the duckbill cavity 1723 is connected to the flow regulating port 1722.

[0143] As a preferred embodiment, please refer to the following for details. Figure 16 , Figure 17 , Figure 18 and Figure 21As shown, the shunt assembly 17 further comprises a diaphragm top cover 173, and the diaphragm top cover 173 is provided with a top cover through hole 1731, and the top cover through hole 1731 communicates with the diaphragm through hole 1724, at this time, the top cover through hole 1731 and the diaphragm through hole 1724 constitute the overflow hole, and the diaphragm top cover 173 is arranged on the side of the shunt balance diaphragm 172 close to the first water inlet 1144, and the flexible check portion 1721 protrudes towards the diaphragm top cover 173 and penetrates the diaphragm top cover 173, that is, as shown in Figure 17 and Figure 18 As shown, the diaphragm top cover 173 is provided with a top cover through hole 1732, and the duckbill-shaped deformation portion 17211 of the flexible check portion 1721 penetrates the top cover through hole 1732 and protrudes out of the top cover through hole 1732 towards the water outlet upper cavity 11482, one end of the balance spring 171 abuts against the inner cavity wall of the water outlet upper cavity 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 support point of the balance spring 171, and the diaphragm top cover 173 has good structural strength. During the shunting 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 of pure water changes or the internal pressure of the water outlet upper cavity 11482 fluctuates, the balance spring 171 can stretch and contract according to the position change of the diaphragm top cover 173, so as to adjust the pressure balance and flow balance of the shunt 1, and ensure the stability of the shunting.

[0144] Further, as shown in Figure 16 , the shunt assembly 17 is provided with a stop limiting portion 1733 protruding towards the side of the first water inlet 1144, so that when the shunt assembly 17 moves relatively towards the side of the first water inlet 1144, the stop limiting portion 1733 abuts against the inner cavity wall of the water outlet cavity 1148, specifically, the stop limiting portion 1733 abuts against the inner cavity wall of the water outlet upper cavity 11482, at this time, the shunt assembly 17 has the maximum displacement. In this way, the stop limiting portion 1733 can abut against the inner cavity wall of the water outlet upper cavity 11482 under the condition of a large pressure difference, forming a reliable mechanical limiting, effectively limiting the further movement of the shunt assembly 17, thereby preventing the shunt balance diaphragm 172 from being deformed too much due to excessive stress, eliminating the hidden danger that the shunt balance diaphragm 172 is damaged due to excessive deformation, and prolonging the service life of the shunt 1.

[0145] Preferably, as shown in Figure 17 , Figure 18 and Figure 21As shown, the stop and limit part 1733 is disposed on the diaphragm top cover 173. Preferably, the stop and limit part 1733 is integrally formed with the diaphragm top cover 173. The stop and limit part 1733 can withstand the impact force generated by collision with the inner wall of the outlet upper cavity 11482. Because the diaphragm top cover 173 has good structural strength, it can ensure that the stop and limit part 1733 will not easily deform or be damaged during frequent displacement and collisions, thereby better maintaining the stability and accuracy of the entire diverter 1. In other embodiments, the stop and limit part 1733 can also be disposed on the diversion balance membrane 172.

[0146] The unexpected effect is that, Figures 17 to 21 As shown, the stop and limit part 1733 is located outside the balance spring 171 and extends circumferentially along the balance spring 171 to constrain the end of the balance spring 171 to the inside of the stop and limit part 1733, thereby ensuring the stability of the balance spring 171 during deformation. It should be noted that the inner diameter of the stop and limit part 1733 can be adapted to the outer diameter of the balance spring 171; alternatively, the inner diameter of the stop and limit part 1733 can be larger than the outer diameter of the balance spring 171. Furthermore, a spring limiting post 1734 can be protruded from the diaphragm top cover 173 facing the first water inlet 1144, and the end of the balance spring 171 is fitted onto the spring limiting post 1734. This, in conjunction with the stop and limit part 1733, achieves a dual constraint on the balance spring 171. In addition, the spring limiting post 1734 can also quickly position the balance spring 171 during assembly, improving assembly efficiency.

[0147] Further details are available according to... Figure 17 As shown, the stop and limit part 1733 is provided with a clearance opening 1735 corresponding to the flexible check part 1721. For example... Figure 20 As shown, the clearance 1735 preferably extends through the stop 1733 along the protruding direction of the stop 1733, so that the stop 1733 is formed into two arc-shaped and oppositely arranged stop portions. Therefore, the number of flexible stop portions 1721 is two, and each flexible stop portion 1721 is located between the two stop portions. This arrangement will have the following unexpected technical effects:

[0148] 1. The clearance opening 1735 provides space for the flexible check valve 1721, allowing the flexible check valve 1721 to protrude and pass through the diaphragm top cover 173 normally. At the same time, it also ensures that each flexible check valve 1721 can deform according to the water flow pressure within a limited space, thereby flexibly adjusting the water flow distribution.

[0149] 2、In the role of the avoidance port 1735, the flexible check portion 1721 on the membrane top cover 173 and the shunt balance membrane 172 can avoid mutual extrusion and friction in the working process, effectively reducing the interference and wear between the flexible check portion 1721 and the stop limiting portion 1733, thereby improving the service life of the shunt assembly 17. The reliability and durability of the shunt balance membrane 172 and the shunt assembly 17 are improved.

[0150] 3、The number of flexible check portions 1721 is configured as two, which can work cooperatively in the face of different water flow pressures and flow rates. For example, when the water flow impacts the shunt balance membrane 172, if there is only one flexible check portion 1721, it may be deformed to one side due to uneven impact of the water flow, resulting in unstable shunting. The two oppositely distributed flexible check portions 1721 can balance such impact force. When one side of the flexible check portion 1721 has a tendency to open due to a larger water flow pressure, the other side of the flexible check portion 1721 can make corresponding adjustments according to the pressure difference, thereby maintaining the stability of shunting, making the water flow from the first water supply port 1144 more uniform and stable.

[0151] 4、Under the action of the avoidance port 1735, when the stop limiting portion 1733 abuts against the inner wall of the water outlet upper cavity 11482, it can also maintain the pure water flowing through the avoidance port 1735 to the first water supply port 1144, ensuring the smoothness, stability and continuity of the pure water flow, and preventing the pure water from being blocked by the stop limiting portion 1733, thereby preventing sudden changes in water flow pressure and ensuring the use stability and reliability of the shunt 1 and the pure drinking system.

[0152] Considering that the stop limiting portion 1733 abuts against the inner wall of the water outlet upper cavity 11482, the water outlet of the first water supply port 1144 is relatively large, i.e., the demand for pure water of the tankless pipeline machine is relatively large, in order to further ensure the supply of pure water, the stop limiting portion 1733 is provided with a water passing gap 1736, i.e., each stop position of the stop limiting portion 1733 is provided with a water passing gap 1736 near the first water supply port 1144 end, the shape and size of the water passing gap 1736 are not limited in this embodiment, which 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 gap 1736, thereby ensuring sufficient pure water flowing to the first water supply port 1144 and supplying the tankless pipeline machine.

[0153] Of course, it should also be noted that in addition to the stop limiting portion 1733 on the shunt assembly 17 abutting against the inner wall of the water outlet upper cavity 11482, the specific Figure 24As shown, the inner cavity wall of the water outlet upper cavity 11482 is protruded to form a stop boss 1161 on the side facing the shunt assembly 17, specifically, the stop boss 1161 is protruded on the side of the inner cavity wall of the water outlet upper cavity 11482 facing the shunt assembly 17, and the stop boss 1161 is preferably integrally formed with the valve body upper shell 116 to facilitate production. The inside of the stop boss 1161 is provided with a first water supply channel 1162 communicating with the first water supply port 1144, and the stop limiting portion 1733 can abut against the stop boss 1161.

[0154] On the one hand, the stop boss 1161 cooperates with the stop limiting portion 1733 on the diaphragm top cover 173 to more accurately limit the deformation degree of the shunt balance diaphragm 172. When the shunt balance diaphragm 172 deforms in the direction of the first water supply port 1144 under the action of water flow, water pressure and other factors, the stop limiting portion 1733 abuts against the stop boss 1161, thereby further preventing the shunt balance diaphragm 172 from deforming excessively and better ensuring that the shunt balance diaphragm 172 works within a safe range. On the other hand, the purified water will be orderly drained 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 disorder, thereby improving the working efficiency and accuracy of the shunt device 1.

[0155] Preferably, specifically according to Figure 24 As shown, the flow channel inner wall of the first water supply channel 1162 is protruded to form a spring force body 1163, and the spring force body 1163 can be optionally extended along the circumference of the first water supply channel 1162, or the number of spring force bodies 1163 is configured to be multiple, and each spring force body 1163 can be optionally a hemispherical body or a prism, and multiple spring force bodies 1163 are arranged along the circumference of the first water supply channel 1162. For example, Figure 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 work, that is, the end of the balance spring 171 abuts against the spring force body 1163, and the circumferential side of the balance spring 171 can contact the flow channel inner wall of the first water supply channel 1162, which well avoids the vibration or slight displacement of the balance spring 171 during work, thereby better ensuring that the balance spring 171 can normally play its balancing and adjusting functions, and more accurately transmitting force, ensuring and improving the shunt accuracy of the shunt device 1.

[0156] Of course, in order to facilitate the assembly of the end of the balance spring 171 into the first water supply channel 1162, please refer to Figure 24The first water supply channel 1162 is used for connecting the port of the water outlet upper cavity 11482, and the port is a second flow guide port. A positioning guide portion 1164 is arranged on the second flow guide port. The positioning guide portion 1164 is connected to the inner wall of the flow channel of the first water supply channel 1162 in a direction along the central axis of the first water supply channel 1162. During assembly, the end portion of the balance spring 171 is only required to be abutted to 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, so as to achieve the purpose of self-positioning, and improve the assembly efficiency and assembly convenience of the balance spring 171.

[0157] As another preferred mode of the embodiment, specifically, please refer to the description of Figure 17 、 Figure 18 and Figure 19 , the shunt assembly 17 further comprises a diaphragm base 174, and the diaphragm base 174 is provided with a base through hole 1741. It can be understood that when the shunt assembly 17 is not configured with the diaphragm top cover 173, the base through hole 1741 and the diaphragm through hole 1724 constitute the overflow hole. Alternatively, when the shunt assembly 17 is configured with the diaphragm top cover 173, the shunt balance diaphragm 172 is clamped 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 overflow hole. The diaphragm base 174 is arranged on the side of the shunt balance diaphragm 172 away from the first water supply port 1144. In this way, when the flow of pure water flowing out of the first water supply port 1144 suddenly decreases, if the water inflow of the water purifier cannot be adjusted in time, the pressure of the water outlet upper cavity 11482 will quickly rise. In this case, the diaphragm base 174 can provide strong support for the shunt balance diaphragm 172. The diaphragm base 174 has a certain structural strength. Due to the support of the diaphragm base 174, the shunt balance diaphragm 172 will not deform excessively towards the reflux guide portion 1171 side due to the reverse pressure. Thus, the stability and reliability of the entire shunt assembly 17 are ensured, and blockage or other faults caused by excessive deformation of the shunt balance diaphragm 172 are avoided. The continuous and stable operation of the water purifier under different working conditions is ensured, the working efficiency and service life of the water purifier are effectively improved, and a more reliable water purification experience is provided for the user.

[0158] 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" described above is 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 shunt balance diaphragm 172.

[0159] Further, specifically, please refer to the description of Figures 17 to 18As shown, the diaphragm base 174 is further provided with a base avoiding hole 1742, the size of the base avoiding hole 1742 is greater than the diameter of the reflux guide part 1171, the reflux guide part 1171 can pass through the base avoiding hole 1742 and abut against the shunt balance membrane 172. In the embodiment, the shape of the base avoiding hole 1742 is not limited, for example, it can be a circular hole, or a square hole, or an oval hole, etc. In this way, the shunt balance membrane 172 can accurately seal the guide flow channel 1172, thereby effectively blocking the reflux path of the pure water. This also ensures that in the normal shunt working state, the water flow can flow in order according to the predetermined shunt channel, avoiding the unnecessary loss or reflux of pure water to interfere with the normal water flow process. At the same time, the flexibility of the shunt balance membrane 172 improves the sealing between the shunt balance membrane 172 and the reflux guide part 1171.

[0160] It should be noted that, as Figure 21 shown, the diaphragm base 174 is provided with a base water flow hole 1743 communicating with the flow adjusting hole 1722. That is, the base water flow hole 1743 on the diaphragm base 174 is correspondingly arranged and communicated with the duckbill cavity 1723 of the flexible check part 1721, ensuring that the pure water can pass through the base water flow hole 1743 and flow into the duckbill cavity 1723, and when the flow adjusting hole 1722 is opened, the pure water can flow into the water outlet upper cavity 11482 through the flow adjusting hole 1722.

[0161] As another preferred mode of the embodiment, specifically according to Figure 21 shown, the diaphragm top cover 173 extends a flow guide extension body 175 towards the diaphragm through hole 1724, the flow guide extension body 175 is preferably integrally formed with the diaphragm top cover 173, and a water passing through hole 1751 is provided inside the flow guide extension body 175. Here, the through hole should be understood as the water passing through hole 1751 penetrating 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 passing through hole 1751 constitute the flow hole. The pure water flows through the water passing through hole 1751, which is equivalent to the pure water flowing from the water outlet lower cavity 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 cavity 11482.

[0162] This design not only effectively guides the flow of purified water through the water passage 1751, making the flow of purified water within the passage more orderly and smooth, reducing turbulence and energy loss, but also, the tight and orderly connection structure between the components allows for precise insertion of the flow guide extension 175 into the diaphragm passage 1724 of the flow-dividing balance membrane 172 and the base passage 1741 of the diaphragm base 174 during assembly, improving positioning accuracy and assembly efficiency.

[0163] Furthermore, please combine Figures 18 to 21 As shown, the flow guide extension 175 passes sequentially through the top cover through hole 1731, the diaphragm through hole 1724, and the base through hole 1741, extending beyond the base through hole 1741. The portion of the flow guide extension 175 extending beyond the base through hole 1741 has a protruding snap-fit ​​protrusion 1752, which snaps onto the diaphragm base 174, thus achieving a snap-fit ​​connection between the diaphragm top cover 173 and the diaphragm base 174. This ensures that the shunt balancing membrane 172 is clamped between the diaphragm top cover 173 and the diaphragm base 174, facilitating convenient and efficient assembly and disassembly, and making subsequent component replacement easier. Furthermore, the structure is simple, reducing the processing cost of each component. Alternatively, the side of the diaphragm base 174 facing away from the shunt balancing membrane 172 can be provided with a base slot, into which the snap-fit ​​protrusion 1752 snaps.

[0164] 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 assembly personnel can observe the diaphragm through hole 1724 of the flow balancing membrane 172 through the buffer gap during the assembly process, facilitating assembly positioning and further improving assembly efficiency. At the same time, the buffer gap serves as space for the deformation of the flow guide extension 175 during the snap-fit ​​process, thereby facilitating the snap-fit ​​protrusion 1752 to snap onto the diaphragm base 174 or to remove the snap-fit ​​protrusion 1752 from the diaphragm base 174.

[0165] It should be noted that in other embodiments, the flow guide extension 175 may also extend from the diaphragm base 174 toward the diaphragm through hole 1724. In this case, the flow guide extension 175 passes through the base through hole 1741, the diaphragm through hole 1724, and the top cover through hole 1731 in sequence and extends out of the top cover through hole 1731. The part of the flow guide extension 175 extending out of the top cover through hole 1731 is provided with a snap-fit ​​protrusion 1752, which is snapped onto the diaphragm top cover 173. This is a conventional replacement method of the above preferred embodiment.

[0166] It should also be noted that, such as Figure 21As shown, the diameter size of the water passing through hole 1751 gradually increases along the water flow direction, which is the direction from the base hole 1741 to the diaphragm hole 1724 and the cover hole 1731 according to the above description, so the diameter size of the water passing through hole 1751 gradually increases along the first direction, which is the direction from the diaphragm base 174 side to the diaphragm cover 173 side along the central axis of the water passing through hole 1751. In this way, when the purified water flows in from the side with a smaller diameter and flows out from the side with a larger diameter, the cross-sectional area of the water passing through hole 1751 gradually increases. According to the flow formula Q=vA (Q is the flow, v is the flow rate, and A is the cross-sectional area), under the condition that the flow remains basically unchanged, the cross-sectional area increases, and the flow rate will decrease. A lower flow rate can reduce the pressure loss of the water flow in the water passing through hole 1751. At the same time, when the purified water flows into the water passing through hole 1751 from the side with a smaller diameter, a relatively orderly flow state can be formed. With the gradual increase in diameter size, the purified water has enough space to transition smoothly, reducing turbulence caused by sudden changes in space, thereby effectively avoiding the generation of small bubbles in the purified water. In addition, the side with a smaller diameter can also limit the impact force of the water flow. Reduce physical damage to the water passing through hole 1751 and the flow distribution balancing membrane 172, such as scratching, etc.

[0167] In the above, the pressure on the side of the flow distribution balancing membrane 172 close to the first water inlet 1144 is significantly different from the pressure on the side of the flow distribution assembly 17 away from the first water inlet 1144, and the flow distribution balancing membrane 172 will elastically deform towards the side of the first water inlet 1144 and drive the diaphragm cover 173 and / or the diaphragm base 174 to move towards the side of the first water inlet 1144. In order to ensure and improve the large elastic deformation of the flow distribution balancing membrane 172 towards the side of the first water inlet 1144, such as Figures 18 to 21 As shown, the flow distribution balancing membrane 172 is provided with a deformation groove 1725, 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 arranged along the circumference of the diaphragm cover 173. It can be understood that the orientation of the slot of the deformation groove 1725 can be set and adjusted according to the structure design and design requirements, and in this embodiment, the slot of the deformation groove 1725 is preferably oriented to the water outlet lower cavity 11481.

[0168] In this way, when the shunt balance membrane 172 is subjected to pressure, the circumferentially extending deformation groove 1725 can provide sufficient space for the deformation of the shunt balance membrane 172, not only making the stress concentrated in the deformation groove 1725, but also enabling the stress to be effectively released, producing uniform deformation, thereby well avoiding the risk of excessive stress concentration in other parts of the shunt balance membrane 172 to cause rupture and fatigue damage. At the same time, it can also effectively enhance the deformation capability of the shunt balance membrane 172 in a limited space. When the shunt balance membrane 172 is affected by the pressure change in the water outlet cavity 1148, the deformation groove 1725 can serve as a pre-set deformation area, better guiding the shunt balance membrane 172 to produce a larger deformation, so that the shunt balance membrane 172 can respond sensitively according to these pressure differences, achieving the purpose of better balancing the pressure in all directions, which is conducive to the shunt assembly 17 to control the shunt more accurately.

[0169] Further, as shown in Figures 18 to 21 , the groove wall of the deformation groove 1725 away from the flexible check portion 1721 is protrudingly formed with a diaphragm clamping portion 1726 outward, preferably, the diaphragm clamping portion 1726 is arranged on the groove wall of the deformation groove 1725 close to the slot side, and the diaphragm clamping portion 1726 is integrally formed with the shunt balance membrane 172, the diaphragm clamping portion 1726 is arranged along the groove length direction of the deformation groove 1725, and the diaphragm clamping portion 1726 is clamped between the valve upper shell 116 and the valve lower shell 117, thereby achieving the purpose that the shunt balance membrane 172 is detachably connected between the valve upper shell 116 and the valve lower shell 117, improving the assembly efficiency of the shunt device 1.

[0170] Specifically, as shown in Figure 24 , the valve lower shell 117 is provided with a diaphragm clamping groove 1173, and the diaphragm clamping portion 1726 is embedded in the inside of the diaphragm clamping groove 1173, so that the diaphragm clamping portion 1726 is more firmly connected between the valve upper shell 116 and the valve lower shell 117, improving the assembly of the shunt balance membrane 172 on the valve shell 11. Furthermore, the diaphragm clamping groove 1173 is arranged on the groove wall close to the flexible check portion 1721 and extends towards the inside of the deformation groove 1725, that is, the diaphragm clamping groove 1173 is accommodated in the inside of the deformation groove 1725 close to the flexible check portion 1721, so that the shunt assembly 17 and the valve shell 11 are more compact, which is conducive to reducing the volume of the shunt device 1. It should be noted that, in addition to the diaphragm clamping groove 1173 being arranged on the valve lower shell 117, the diaphragm clamping groove 1173 is arranged on the valve upper shell 116.

[0171] Preferably, as shown in Figure 24As shown, the valve body upper shell 116 is provided with a diaphragm anti-falling groove 1165, and the diaphragm clamping portion 1726 is provided with a diaphragm anti-falling body 1727 inserted into the diaphragm anti-falling groove 1165, thereby further improving the stability of the connection between the shunt balance diaphragm 172 and the valve shell 11. It can be understood that the diaphragm clamping groove 1173 is arranged on the valve body upper shell 116, and the diaphragm anti-falling groove 1165 is correspondingly arranged on the valve body lower shell 117.

[0172] In the pure drinking system, when the user starts or turns off the tankless pipeline machine, the flow rate of the pure water flowing through the shunt 1 will change sharply, thereby causing the water hammer phenomenon. The instantaneous pressure wave generated by the water hammer may cause damage to the shunt assembly 17 in the shunt 1. Based on this, the inventors also provide a preferred mode, please see Figure 17 and Figure 16 The shunt 1 further comprises a water hammer absorber 18, which is located between the shunt assembly 17 and the pure water inlet 1143, and is detachably connected to the valve shell 11. Specifically, the water hammer absorber 18 is installed inside the water outlet lower cavity 11481, so that the pressure wave generated by the water hammer is buffered before entering the water outlet upper cavity 11482.

[0173] In this way, the pressure wave can be buffered before reaching the shunt assembly 17, reducing the risk of damage to the shunt assembly 17 caused by the high pressure generated by the water hammer, and improving the service life of the shunt 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 shell 11. In addition, under the action of the water hammer absorber 18, the stability of the shunt assembly 17 during adjustment can be ensured, the interference of the water hammer on the shunting process is reduced, the normal operation of the shunt 1 is ensured, and the shunting precision of the shunt 1 is improved.

[0174] Preferably, as shown in Figure 24 Preferably, as shown in

[0175] In addition, the presence of the water flow buffer hole 181 can also adjust the pressure change of the water flow. According to Bernoulli's principle, when the water flow passes through the water flow buffer hole 181, a certain pressure difference will be formed on both sides of the water hammer absorbing piece 18, which plays a certain degree of adjustment. 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, which can alleviate the sharp rise of the pressure, making the pressure change more gentle, and further reducing the water hammer phenomenon.

[0176] It should be noted that the number, size and distribution of the water flow buffer hole 181 are not limited in the present application, and can be set and adjusted according to the structure design and design requirements. By reasonably setting the number, size and distribution of the water flow buffer hole 181, the pulse frequency of the pure water flow can also be changed. For example, when the water hammer phenomenon occurs, high-frequency pressure pulses will appear. The water flow buffer hole 181 is configured in a combination of large and small holes, wherein the large hole allows a larger flow of water to pass through, and the small hole has more restrictions on the water flow, so that the high-frequency pressure pulse can be converted into a relatively low-frequency pulse (i.e. the irregular pulse becomes more regular), and the low-frequency and regular pressure change has relatively small impact on the flow divider 1, thereby also helping to reduce the harm of water hammer.

[0177] Further, as shown in Figure 24 and Figure 25 , the water hammer absorbing piece 18 is provided with a positioning assembly hole 182 for inserting the backflow guide part 1171, and the hole diameter of the positioning assembly hole 182 is matched with the diameter of the backflow guide part 1171, so that the backflow guide part 1171 can be quickly and stably installed on the valve body lower shell 117 of the valve shell 11. In order to ensure that the water hammer absorbing piece 18 can be more stably installed on the valve body lower shell 117, and the stress between the water hammer absorbing piece 18 and the valve body lower shell 117 is more balanced, the inner wall of the outlet lower cavity 11481 is protruded to form an absorbing piece boss 1174, and the edge part of the water hammer absorbing piece 18 abuts against the absorbing piece boss 1174, which is simple in structure and convenient to disassemble and assemble, and is beneficial to subsequent maintenance and repair.

[0178] Of course, as shown in Figure 25 , the absorbing piece boss 1174 is protruded to form a limiting protrusion 1175 towards one side of the flow dividing assembly 17, and the edge part of the water hammer absorbing piece 18 is provided with a limiting gap 183 for inserting the limiting protrusion 1175. In this way, the limiting gap 183 and the limiting protrusion 1175 cooperate to prevent the water hammer absorbing piece 18 from being deflected around the backflow guide part 1171, thereby more stably guiding the flow of pure water.

[0179] In some other embodiments, the water hammer absorber 18 can also be a piston type water hammer eliminator, or a diaphragm type water hammer eliminator, both of which are relatively mature existing technologies in the water hammer eliminator field, and their structures will not be described in detail here. Alternatively, the water hammer absorber 18 can also be a slow closing check valve.

[0180] As a preferred mode of the present embodiment, please refer to Figure 22 、 Figure 23 and Figure 24 , the shunt 1 further comprises a water filtering member 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 purified water inlet 1143 through the water inlet channel 1176, the water filtering member 19 is arranged in the water inlet channel 1176, the water filtering member 19 is provided with a filtering hole 191 in the extension direction of the water inlet channel 1176, and a water passing gap is formed between the circumferential side wall of the water filtering member 19 and the inner side wall of the water inlet channel 1176, the circumferential side wall of the water filtering member 19 is provided with a water discharge opening 192 connected to the water passing gap, and the opening size of the water discharge opening 192 is larger than the hole diameter of the filtering hole 191.

[0181] In this way, since the filtering hole 191 arranged on the water filtering member 19 can further filter the water flow in the direction of the purified water, it can prevent small particles from flowing into the water outlet chamber 1148 and the water tankless pipeline machine when the filter core of the water purifier approaches the end of its service life, thereby ensuring and improving the purity of the purified water supplied to the water tankless pipeline machine and the faucet, and improving the taste and quality of the drinking water.

[0182] More importantly, when the purified water passes through the filtering hole 191 of the water filtering member 19, the water flow will generate a certain resistance when passing through the filtering hole 191 due to the relatively small hole diameter of the filtering hole 191. The presence of the water discharge opening 192 can play a role in water diversion. The opening size of the water discharge opening 192 is larger than the hole diameter of the filtering hole 191, and a part of the water can flow through the water discharge opening 192 and the water passing gap, thereby sharing part of the water flow, so that the water flow rate through the filtering hole 191 will not be too high, thereby reducing the water resistance of this part. At the same time, the presence of the water discharge opening 192 and the water passing gap also helps to balance the pressure in the water inlet channel 1176, and the water can be redistributed between the filtering hole 191 and the water discharge opening 192, so that the pressure distribution in the entire water inlet channel 1176 is more uniform, and the water resistance of the water inlet channel 1176 and the entire shunt 1 is also reduced.

[0183] Preferably, please refer to Figure 22 、 Figure 23 and Figure 24The water filtering part 19 comprises a body fastening part 193 and a body water filtering part 194 fixedly connected with the body fastening part 193, and the fixed connection is preferably one-piece forming, facilitating production and manufacture. The water discharging through hole 192 and the filtering hole 191 are both arranged on the body water filtering part 194. Specifically, the body water filtering part 194 has a water filtering part bottom wall and a water filtering part side wall extending along the circumferential side of the water filtering part bottom wall, and the water filtering part bottom wall and the water filtering part side wall cooperatively enclose a filtering cavity. The filtering cavity has a filter cavity opening arranged opposite to the water filtering part bottom wall. The filtering hole 191 is arranged on the water filtering part bottom wall, the water discharging through hole 192 is arranged on the water filtering part side wall, the body fastening part 193 is arranged on one side of the water filtering part side wall close to the filter cavity opening, and the body fastening part 193 is arranged extending along the circumference of the filter cavity opening. The body fastening part 193 is formed protruding outwardly from the water filtering part side wall, so that when the water filtering part 19 is inserted into the water inlet flow channel 1176, the body fastening part 193 is detachably connected to the valve body lower shell 117 of the valve shell 11, and the body water filtering part 194 and the flow channel inner side wall of the water inlet flow channel 1176 automatically form a water passing gap.

[0184] It should be noted that the water discharging through hole 192 is a water discharging group, which comprises a plurality of water discharging holes arranged along the circumference of the body water filtering part 194, and the diameter of each water discharging hole is larger than the diameter of the filtering hole 191. The water discharging group can be configured as one group, or as a plurality of groups. The plurality of water discharging groups are arranged uniformly along the extension direction of the water inlet flow channel 1176. Alternatively, as shown in Figure 23 , the water discharging through hole 192 can also be in the shape of a strip hole, and the water discharging through hole 192 is arranged extending along the circumferential part of the body water filtering part 194. The number of the water discharging through hole 192 can be one or a plurality of, and the plurality of water discharging through holes 192 are arranged and distributed along the extension direction of the water inlet flow channel 1176, and preferably, the adjacent two water discharging through holes 192 are arranged staggered.

[0185] Preferably, as shown in Figure 22As shown, the filter buckle body 1177 is arranged on the inner side wall of the water inlet channel 1176, and extends along the circumferential direction of the water inlet channel 1176. The body fastening part 193 is clamped with the filter buckle body 1177, and the filter buckle body 1177 extends along the extension direction of the water inlet channel 1176. Further, the filter buckle body 1177 is provided with a fastening clamping groove, and the body fastening part 193 is provided with a fastening protrusion 195, and the fastening clamping groove is connected with the fastening protrusion 195 in a plug-in manner. In this way, the filter element 19 is effectively and stably connected to the inside of the water inlet channel 1176, and the filter element 19 will not be easily displaced under the long-term impact of the water flow, so as to ensure that the filter hole 191 and the drain opening 192 can normally play a role and maintain the stability of the filtering function. At the same time, the filter buckle body 1177 is clamped in the filter clamping groove, and the fastening clamping groove is connected with the fastening protrusion 195 in a plug-in manner, so that the installation of the filter element 19 is more convenient. When assembling the flow divider 1, the worker only needs to align the filter element 19 with the water inlet channel 1176 and clamp it to complete the installation, which is also convenient for later disassembly, cleaning and replacement and maintenance. It should be noted that, in addition to the above-mentioned mode that the fastening clamping groove is arranged on the filter buckle body 1177 and the fastening protrusion 195 is arranged on the body fastening part 193, the fastening clamping groove can also be arranged on the body fastening part 193, and the fastening protrusion 195 is correspondingly arranged on the filter buckle body 1177.

[0186] As a preferred mode of the present embodiment, the flow divider 1 further comprises a water resistance element for increasing the resistance of the water flow. The valve body lower shell 117 of the valve shell 11 is provided with a second water supply channel 1178, and the second water supply opening 1145 is connected with the water outlet cavity 1148 through the second water supply channel 1178. The water resistance element is arranged in the second water supply channel 1178 and is detachably connected with the valve shell 11. In this way, pressure fluctuations caused by water flow impact can be effectively avoided. When the faucet is suddenly opened or closed, the sharp change of water flow speed will cause water hammer phenomenon, resulting in instantaneous increase of pressure in the second water supply channel 1178. The resistance of the water resistance element to the water flow can slow down the sudden change of water flow speed, thereby buffering the pressure change. At the same time, the water resistance element can also play a certain role in preventing backflow. When the pressure in the second water supply channel 1178 suddenly decreases, backflow of water may occur. Since the water resistance element can increase the resistance of backflow, the possibility of backflow is reduced.

[0187] In the present embodiment, specific reference is made to Figure 22 and Figure 24As shown, the water passing support frame 1131 with the support water outlet 1134 is arranged 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 arranged staggered. The water channel inner wall 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 arranged inside the second water supply channel 1178, and is preferably integrally formed with the valve body lower shell 117. The water resistance member abuts and connects the water passing support frame 1131. Further, the side of the water passing support frame 1131 facing the water outlet cavity 1148 is protrudingly arranged with a support positioning portion 1132. The water resistance member can be arranged with a water resistance insertion port for inserting the support positioning portion 1132, so that the water resistance member can be stably installed and fixed on the support positioning portion 1132.

[0188] Preferably, as shown in Figure 22 , Figure 24 and Figure 25 As shown, the flow channel inner wall of the second water supply channel 1178 is protrudingly arranged with a bearing protrusion 1133. The bearing protrusion 1133 is arranged extending along the extension direction of the second water supply channel 1178. The water resistance member abuts the bearing protrusion 1133, so that the water resistance member is more stably installed inside the second water supply channel 1178. Further, the cross-sectional area of the bearing protrusion 1133 gradually increases from the side close to the water outlet cavity 1148 to the side close to the second water outlet 1145. In this way, during the molding process of manufacturing the valve body lower shell 117, the draft of the bearing protrusion 1133 is used to more easily separate the mold and the valve body lower shell 117, and during demolding, the bearing protrusion 1133 may be torn or deformed, affecting product quality. At the same time, since the cross-sectional area of the bearing protrusion 1133 gradually increases, when installing the water resistance member, it is equivalent to having a guiding effect. The water resistance member can more easily slide into the correct installation position along the direction of the draft, which helps 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 of the bearing protrusion 1133 with a larger cross-sectional area 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 displace in the flow channel direction, ensuring that the water resistance member stably and normally exerts resistance on the water flow. In addition, the bearing protrusion 1133 can better guide the water flow of pure water. Since the cross-sectional area of the bearing protrusion 1133 gradually increases, the water flow will change direction more smoothly when passing through the bearing protrusion 1133, reducing the degree of turbulence of the water flow, thereby improving the stability and uniformity of the water flow.

[0189] As a preferred mode of the present embodiment, the water resistance member includes a water resistance member body, a plurality of flow-limiting water resistance holes are arranged on the water resistance member body, each flow-limiting water resistance hole is communicated with the support water outlet 1134, and the water resistance member body is connected with the above-mentioned bearing protrusion 1133. In this way, when the purified 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 the water, but also make the water flow out in a foamy state, and the plurality of flow-limiting water resistance holes communicated with the support water outlet 1134 can also make the water flowing out of the water outlet more evenly dispersed, achieving water saving while preventing water splashing. In some embodiments, the water resistance member can be selected as a one-way valve assembly, and can also be selected as a throttle valve, and can also be selected as a bubbler.

[0190] The unexpected effect is that, as shown in Figure 24 When the water hammer absorbing member 18 is installed to the water outlet lower cavity 11481, the water hammer absorbing member 18 will better restrict the water resistance member completely 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 absorbing member 18 is installed upstream of the water flow of the water resistance member, it can absorb and buffer before the water hammer pressure wave reaches the water resistance member. This can protect the water resistance member from being damaged due to bearing too high water hammer pressure, ensure that the water resistance member can normally play its functions of limiting water flow, adjusting pressure, etc., more accurately control the water flow according to the designed flow-limiting water resistance holes and other structures, so as to provide more stable water inlet conditions for the subsequent faucet or other water outlet equipment, reduce the impact of water hammer on the faucet, thereby prolonging the service life of the faucet and reducing the frequency of maintenance and replacement.

[0191] It should be noted that, in order to reduce the vibration of the water resistance member during the water resistance treatment process, the circumferential wall of the water resistance member body can also be provided with a bearing insertion slot for inserting and connecting the bearing protrusion 1133. In addition, the aperture of the flow-limiting water resistance hole is between 0.5-1.5mm to provide a relatively stable water flow resistance, thereby avoiding the risk of blockage during long-term use.

[0192] As a preferred mode of the embodiment, the flow distributor 1 further comprises a water inlet filter arranged at the raw water inlet 1141, wherein the water inlet filter is preferably a filter screen. In this way, it can effectively prevent some large-particle impurities (such as silt, etc.) possibly contained in tap water from flowing into the water inlet cavity 1147, achieving the purpose of preliminary filtration, avoiding the risk of damage to the pressure regulating assembly 16 inside the flow distributor 1 and the risk of pressure stabilization failure of the flow distributor 1, and also reducing the total amount of impurities entering the water purifier, to some extent, prolonging the service life of the filter element of the water purifier. In combination with the water filter 19 arranged at the purified water inlet 1143, not only the purpose of double filtration of the flow distributor 1 is achieved, that is, although the purified water filtered by the water purifier has removed most of the impurities, bacteria and harmful substances, it may still be contaminated in the delivery process, such as particle 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 purified water flowing to each water terminal is more pure. At the same time, the effect of triple filtration of the water source by the water purification system is achieved, thereby effectively ensuring that the water purification system has good water quality and provides safer drinking water for users.

[0193] In the above, the excess purified water inside the water outlet cavity 1148 can flow back to the backflow cavity 1146 under the regulation of the flow distribution assembly 17, and the backflow cavity 1146 can converge the excess water flowing back from the flow distribution assembly 17 after the pressure stabilization of the pressure regulating assembly 16 and output from the raw water outlet 1142 to the water purifier, so that the water source can be redistributed and utilized inside the water purification system, reducing the waste of water source. However, when the water amount of the excess water flowing back from the water outlet cavity 1148 to the backflow cavity 1146 is much smaller than the water amount of the pressure stabilized water delivered from the water inlet cavity 1147 to the backflow cavity 1146, that is, the pressure on the side of the backflow cavity 1146 close to the water outlet cavity 1148 is less than the pressure on the side of the backflow cavity 1146 close to the water inlet cavity 1147, which is easy to cause the pressure stabilized water entering the backflow cavity 1146 to flow back to the water outlet cavity 1148, thereby affecting the water quality of the domestic water and the direct drinking water.

[0194] Based on this, a preferred mode is also disclosed in the embodiment of the present application, which is specifically described as follows: Figure 3As shown, the flow divider 1 further comprises a one-way flow guide 13 arranged in the backflow cavity 1146 to prevent the steady water flowing through the water inlet cavity 1147 from flowing back to the water outlet cavity 1148, and to output the excess water flowing back to the water outlet cavity 1148 to the water purifier after being combined with the steady water. This not only prevents the steady water flowing through the water inlet cavity 1147 from flowing back to the water outlet cavity 1148, which causes the pure water in the water outlet cavity 1148 to be mixed with the steady water, but also ensures the water quality and quantity of the pure water supplied by the flow divider 1. At the same time, the pressure of the water outlet cavity 1148 and the water inlet cavity 1147 is maintained, so that the water flow in the water outlet cavity 1148, the water inlet cavity 1147 and the backflow cavity 1146 can be in the designed direction and pressure condition, thereby ensuring the stability of the simplified pipe elements and connections of the water purifying system.

[0195] The unexpected effect is that the one-way flow guide 13 is assembled in the backflow cavity 1146 of the valve shell 11, so that the assembly between the one-way flow guide 13 and the valve shell 11 is more compact. In the water purifying system with limited space, the integration of such assembly is higher, which saves the space occupation and effectively simplifies the pipe layout of the water purifying system and reduces the risk of leakage due to excessive pipe connections. In addition, it can also prevent damage to the flow divider 1 and the water purifying system due to water hammer phenomenon. Understandably, when the external water supply pipe pressure rises instantaneously, the inertia of the water flow will cause water hammer effect, generating a very high pressure wave. At this time, the one-way flow guide 13 can prevent the high pressure wave from impacting the one-way flow guide 13 in reverse direction, which is beneficial to prolong the service life of the flow divider 1 and reduce the maintenance cost of the flow divider 1 and the water purifying system.

[0196] As a preferred mode of the present embodiment, please refer to Figure 8 , Figure 9 and Figure 10As shown, the one-way flow guide 13 includes a check body 131 and a mixed flow guide 132. The check body 131 has an input port 1311 and an output port 1312, and is configured to control the flow of the water source from the input port 1311 to the output port 1312. It is understood that the water source refers to the excess water flowing back to the backflow cavity 1146 from the water cavity 1148. The mixed flow guide 132 has a flow guide channel 1321 inside, and a protruding extension 133 with a liquid injection port 1331 protruding from one side of the mixed flow guide 132. The extension 133 extends along the circumferential portion of the mixed flow guide 132 and is arranged at the end of the mixed flow guide 132. One end of the check body 131 arranged with the output port 1312 abuts against the extension 133 to form a mixed cavity 1332. At this time, the opening formed by the combination of the mixed flow guide 132, the extension 133, and the check body 131 is the liquid injection port 1331, which is in communication with the mixed cavity 1332. The output port 1312 is also in communication with the mixed cavity 1332, and the input port 1311 is in communication with the water cavity 1148.

[0197] Further, as shown in Figure 6 and Figure 7 , the liquid injection port 1331 of the one-way flow guide 13 is arranged towards the water inlet cavity 1147, i.e., the liquid injection port 1331 is aligned with the water inlet cavity 1147, and the liquid injection port 1331 is in communication with the water inlet cavity 1147. The steady pressure water flowing into the backflow cavity 1146 will flow into the mixed cavity 1332 through the liquid injection port 1331. The input port 1311 of the check body 131 is in communication with the water outlet cavity 1148, and the flow guide channel 1321 is in communication with the raw water outlet 1142 of the valve lower shell 117. Therefore, the excess water can only flow into the mixed cavity 1332 from the input port 1311 of the check body 131 and then through the output port 1312. At this time, the excess water is mixed with the steady pressure water, and the mixed water is guided by the flow guide channel 1321 to the raw water outlet 1142 and then to the water purifier. When the pressure of the mixed cavity 1332 is too large, i.e., the pressure on the side of the backflow cavity 1146 close to the water outlet cavity 1148 is less than the pressure on the side of the backflow cavity 1146 close to the water inlet cavity 1147, the check body 131 will be closed under the action of the pressure, thereby preventing the steady pressure water from flowing back to the water outlet cavity 1148.

[0198] It should be noted that, in order to ensure that the extension 133 can abut more stably on the end face of the check body 131 arranged with the input port 1311. As shown in Figures 6 to 11As shown, the auxiliary support part 135 is arranged on one side of the check body 131 protruding from the mixing flow guide 132, is preferably distributed opposite to the extension part 133, and has a length dimension equal to that of the extension part 133, and an end of the auxiliary support part 135 away from the mixing flow guide 132 abuts against the check body 131. In this way, the auxiliary support part 135 and the extension part 133 both abut against the check body 131, not only achieving a more balanced force between the mixing flow guide 132 and the check body 131, but also improving 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.

[0199] Preferably, in particular in combination with Figure 6 and Figure 7 As shown, the outer side wall of the extension part 133 is provided with a positioning protrusion 1322, the extension direction of the positioning protrusion 1322 is consistent with that of the flow guide channel 1321, and the positioning protrusion 1322 is located on one side of the liquid injection port 1331. The valve shell 11 is provided with a positioning groove 1149 located inside the backflow cavity 1146, and the positioning groove 1149 extends along the extension direction of the backflow cavity 1146. When the one-way flow guide 13 is assembled into the backflow cavity 1146, the positioning protrusion 1322 is inserted into the positioning groove 1149, and through the cooperation between the positioning protrusion 1322 and the positioning groove 1149, the liquid injection port 1331 of the one-way flow guide 13 can be self-aligned with the water inlet cavity 1147, i.e., the pressure relief cavity discharge port 1151 is aligned with the liquid injection port 1331, and the liquid injection port 1331 fully covers the pressure relief cavity discharge port 1151, so that the stable water can flow more smoothly through the pressure relief cavity discharge port 1151 and the liquid injection port 1331 and into the mixing cavity 1332, thereby avoiding the problem of water pressure instability caused by turbulence or vortex due to the obstruction of stable water.

[0200] In addition, during the assembly of the one-way flow guide 13 into the backflow cavity 1146, only the positioning protrusion 1322 of the one-way flow guide 13 needs to be aligned and slid into the positioning groove 1149 inside the backflow cavity 1146, which improves the convenience and efficiency of assembling the one-way flow guide 13, facilitates the subsequent disassembly and maintenance of the one-way flow guide 13, improves the efficiency of repairing the flow divider 1, and ensures the stability of the flow divider 1 during long-term use. Since the positioning protrusion 1322 is limited by the positioning groove 1149, it effectively prevents the one-way flow guide 13 from being deflected and displaced in the backflow cavity 1146, ensures that the liquid injection port 1331 of the one-way flow guide 13 is always aligned with the pressure relief cavity discharge port 1151 of the valve shell 11, reduces the impact and vibration of the valve shell 11 caused by the stable water, and further reduces the noise of the flow divider 1 during use.

[0201] Further, in particular in combination with Figure 9 and Figure 10As shown, the 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 is offset from the extension 133 to form a shoulder portion 134. Understandably, the cross-sectional size of the shoulder end is larger than that of the extension 133, and the shoulder portion 134 is the portion where the shoulder end connects with the extension 133 and the cross-sectional size changes. As shown, Figure 7 As shown, the valve shell 11 is provided with a stepped limiting portion 1152 inside the return flow cavity 1146, that is, the inner wall of the passage of the return flow cavity 1146 is protruded to form the stepped limiting portion 1152 inside the return flow cavity 1146, and the shoulder end of the one-way flow guide 13 abuts against the stepped limiting portion 1152 of the valve shell 11, so that the shoulder portion 134 of the one-way flow guide 13 can enable the mixing flow guide 132 to move horizontally in the extension direction of the positioning protrusion 1322.

[0202] In this embodiment, the mixing flow guide 132 of the one-way flow guide 13 is inserted into the inside of the return flow cavity 1146 under the guidance of the positioning groove 1149, until the shoulder portion 134 abuts against the stepped limiting portion 1152 of the valve shell 11, thereby limiting the movement of the mixing flow guide 132 in the extension direction of the return flow cavity 1146, achieving the purpose of efficient positioning.

[0203] Preferably, as shown in Figure 8 , Figure 9 and Figure 10 , a drainage slope 136 is arranged between the inner wall of the mixing cavity 1332 and the passage inner wall of the flow guide passage 1321, and the drainage slope 136 extends from the mixing cavity 1332 to the flow passage inner wall of the flow guide passage 1321. In this way, it can not only avoid the unstable phenomenon of large impact force and local turbulence caused by the height difference during the process of the stable water flowing from the mixing cavity 1332 to the flow guide passage 1321 in a short time, but also ensure that the stable water is sequentially mixed in the mixing cavity 1332, the flow guide passage 1321, and then transported from the raw water outlet 1142 to the water purifier in a relatively stable speed and state.

[0204] As a preferred mode of this embodiment, as shown in Figure 8 and Figure 9 , 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 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. Understandably, the water pressure on the side of the input port 1311 is equivalent to the pressure on the side of the return flow cavity 1146 close to the water outlet cavity 1148, and the water pressure on the side of the output port 1312 is equivalent to the pressure on the side of the return flow cavity 1146 close to the water inlet cavity 1147.

[0205] 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 to the water outlet cavity 1148 towards the backflow cavity 1146 can enter the fixed shell 1313 through the input port 1311, and then flow through the fixed shell 1313 and enter the mixing cavity 1332 from the output port 1312. 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 to close the input port 1311, so that the stable water in the mixing cavity 1332 cannot flow back to the water outlet cavity 1148 through the fixed shell 1313, achieving the purpose of one-way flow control of excess water.

[0206] Preferably, as shown in Figure 10 and Figure 11 The valve core body 1314 includes a movable opening and closing part 13141 and an elastic reset part 13142. The elastic reset part 13142 is preferably a spring, but it can also be a component made of elastic material such as rubber material or silicone material. 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 abut against the movable opening and closing part 13141 and the fixed shell 1313, respectively. Specifically, the movable opening and closing part 13141 is provided with a spring embedding slot, and the shape and size of the spring embedding slot are matched with those of the elastic reset part 13142. The end of the elastic reset part 13142 is embedded in the spring embedding slot to prevent the elastic reset part 13142 from deviating during deformation.

[0207] 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 input port 1311, effectively preventing the stable 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, the elastic reset part 13142 is extruded to deform, so that the input port 1311 is connected with the output port 1312. At this time, the 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 less 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 towards the side of the input port 1311 under the action of the deformation recovery of the elastic reset part 13142, and then the sealing head 13143 abuts against the input port 1311 to prevent the stable water from flowing through the input port 1311 and entering the water outlet cavity 1148.

[0208] To ensure the sealing between the sealing head 13143 and the input port 1311, please refer to Figure 10 and Figure 11 As shown, the sealing head 13143 is provided with a first sealing groove extending along the circumference of the sealing head 13143, and a check sealing ring 13144 is embedded in the first sealing groove. Under the action of the check sealing ring 13144, the sealing 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 have flexible contact with the fixed shell 1313 during the opening and closing process, reducing the wear of the check valve 131 during frequent opening and closing, thereby effectively improving the service life of the check valve 131 and the one-way flow guide.

[0209] Preferably, as shown in Figure 10 and Figure 11 The above fixed shell 1313 includes a valve seat shell 13131 and a retaining inner frame 13132, the valve seat shell 13131 is sleeved on the outside of the retaining inner frame 13132, the movable opening and closing part 13141 is inserted into the retaining inner frame 13132, the end of the elastic return 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 valve 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 return part 13142 of the valve core body 1314 on the movable opening and closing part 13141, and finally embed the retaining inner frame 13132 inside the valve seat shell 13131 and make the movable opening and closing part 13141 inserted into the retaining inner frame 13132, so as to complete the assembly of the check valve 131. At this time, the sealing head 13143 of the movable opening and closing part 13141 abuts and seals against the input port 1311 on the valve seat shell 13131, and the elastic return part 13142 is in a compressed deformed state. In this way, the valve seat shell 13131 and the retaining inner frame 13132 can be produced separately, reducing the manufacturing difficulty of the fixed shell 1313, thereby facilitating the reduction of the manufacturing cost of the fixed shell 1313. At the same time, it is also convenient for the assembly of the check valve 131, improves the assembly efficiency of the check valve 131, and reduces the assembly cost of the check valve 131.

[0210] Specifically, please refer to Figure 8The retaining inner frame 13132 is provided with a retaining arm 13134 located on the inner side of the output port 1312, i.e., the retaining arm 13134 extends from the retaining inner frame 13132 towards the inner side of the output port 1312. The retaining arm 13134 is provided with a guide insertion hole 13136 of the plug-in movable opening and closing part 13141. The shape of the guide insertion hole 13136 can be selected to be suitable for the shape of the end of the movable opening and closing part 13141. Of course, the shape of the guide insertion hole 13136 can also be selected to be different from the shape of the end of the movable opening and closing part 13141, but it must be ensured that the side wall of the end of the movable opening and closing part 13141 abuts and contacts the inner hole wall of the guide insertion hole 13136, so that the movable opening and closing part 13141 can reciprocate along the central axis direction of the guide insertion hole 13136, so that the guide insertion hole 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 abuts on the input port 1311. The end of the elastic reset part 13142 abuts the retaining arm 13134.

[0211] It should be noted that the specific Figures 8 to 11 As shown, the retaining arm 13134 is provided with a limiting boss 13135 protruding towards the movable opening and closing part 13141, and the guide insertion hole 13136 penetrates 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 insertion 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 embedding slot provided on the movable opening and closing part 13141, which not only ensures that the elastic reset part 13142 is stably assembled in the fixed shell 1313, but also further prevents the elastic reset part 13142 from deviating during deformation.

[0212] Further, the specific Figure 10 In order to reduce the weight of the fixed shell 1313 and the check body 131, reduce the production materials of the fixed shell 1313, and further reduce the production cost of the fixed shell 1313 and the check body 131, at least one material reduction port 13133 is provided on the side wall of the retaining inner frame 13132. The shape, size and number of the material reduction port 13133 are not limited here and can be set and adjusted according to the structure design and design requirements.

[0213] It should be noted that in order to ensure the sealing between the valve seat shell 13131 of the fixed shell 1313 and the inner wall of the reflux cavity 1146, please refer to Figures 6 to 11As shown, the valve seat shell 13131 is provided with a second sealing groove extending along the circumference of the valve seat shell 13131, and an outer sealing ring 137 is embedded in the second sealing groove. Under the action of the outer sealing ring 137, the sealing property between the fixed shell 1313 of the check body 131 and the inner wall of the reflux cavity 1146 can be effectively improved.

[0214] It should also be added here that, in order to firmly install the above-mentioned one-way flow guide 13 in the reflux cavity 1146 of the valve shell 11, specific reference should be made to Figure 6 and Figure 7 As shown, a pipe joint 14 is assembled at the raw water outlet 1142, and the one-way flow guide 13 is completely constrained in the reflux cavity 1146 by the pipe joint 14, and a conduit can also be connected through the pipe joint 14.

[0215] In addition, as shown in Figure 3 , Figure 6 , Figure 7 The pipe joint 14 and the one-way flow guide 13 can also be configured with at least one fastening sealing ring 15. On the one hand, the end of the conduit is provided through the fastening sealing ring 15, which improves the sealing property between the conduit and the reflux cavity 1146, effectively prevents the steady water from the raw water outlet 1142 and the pipe joint 14 from seeping out, and also makes the conduit more firmly connected to the flow divider 1. On the other hand, by using the elasticity of the fastening sealing ring 15, the pipe joint 14 and the one-way flow guide 13 are flexibly connected, and when the pipe joint 14 is assembled to the raw water outlet 1142, the fastening sealing 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 sealing ring 15 to automatically fill the assembly gap between the pipe joint 14 and the one-way flow guide 13, and to adaptively change its shape according to the size and shape of the assembly gap. At the same time, the elastic deformation also enables the fastening sealing ring 15 to compensate for the gap changes caused by factors such as expansion and vibration of the flow divider 1 during operation, thereby maintaining the stability of the assembly gap.

[0216] Of course, the pipe joint 14 can also be other quick connectors or quick connectors. Similarly, the pipe joint 14 and the above-mentioned fastening sealing ring 15 are also adapted to be installed at the raw water inlet 1141, the pure water inlet 1143, the first water supply port 1144 and the second water supply port 1145. The model size of the pipe joint 14 can be appropriately adjusted according to the raw water inlet 1141, the pure water inlet 1143, the first water supply port 1144 and the second water supply port 1145.

[0217] The above is the explanation and description of the flow divider proposed in the embodiments of the present application, and since the pure drinking system proposed in the embodiments of the present application adopts all the technical solutions of the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.
