Description

Technical Field

[0001] This application relates to the technical field of water manifolds, and in particular to a water manifold. Background Technology

[0002] A manifold is a widely used device in water treatment systems. Its function is to distribute water flow into different treatment paths or to combine water flow that has passed through different treatment paths. It is mainly used in underfloor heating systems.

[0003] Existing manifolds, refer to Figure 1 It includes a main pipe connector 1 and branch pipe connectors 2, with multiple branch pipe connectors 2 connected to the main pipe connector 1. In use, both the main pipe connector 1 and the branch pipe connectors 2 are connected to external pipes for water distribution or collection.

[0004] Existing manifolds typically employ a fixed-number design, meaning the number of branch pipe connections is predetermined during the design and manufacturing process, thus limiting their application. Adding more processing paths requires replacing the entire manifold or undertaking complex modifications, increasing maintenance complexity. Summary of the Invention

[0005] In order to expand the application range of the water manifold, this application provides a water manifold.

[0006] This application provides a water distribution manifold, which adopts the following technical solution: A water distribution manifold includes multiple water distribution manifold modules connected in sequence. Each water distribution manifold module includes a main connecting pipe and a water distribution head. The water distribution head is connected to and communicates with the main connecting pipe. The main connecting pipe is provided with an opening and closing element for opening and closing the water distribution head. The main connecting pipes on any two adjacent water distribution manifold modules are connected.

[0007] By adopting the above technical solution, the main connecting pipes are sequentially connected by splicing the manifold modules, and the number of water distribution heads is adjusted. This allows the manifold to be combined into any number of paths according to actual needs, flexibly adapting to various installation scenarios and requirements. The opening and closing mechanism can distribute the water flow in the main connecting pipes to the water distribution heads, simplifying the maintenance and replacement of the water distribution heads and reducing maintenance costs and downtime.

[0008] Optionally, the two opposite ends of the main connecting pipe are connected. One end of the main connecting pipe is provided with a plug, and the other end of the main connecting pipe is provided with a slot and a limiting member. Two adjacent water distribution modules are spliced ​​by inserting the plug of one water distribution module into the slot of the other water distribution module. The limiting member is provided on the slot wall of the main connecting pipe and is used to engage with the plug inserted into the slot to limit the plug.

[0009] By adopting the above technical solution, the plug of one main connecting pipe is inserted into the slot of another main connecting pipe to quickly connect and connect the two manifold modules, and the plug is limited by the limiting component to improve the stability between the two manifold modules.

[0010] Optionally, one end of the main connecting pipe is provided with a protrusion, and the other end of the main connecting pipe is provided with a recess, and the protrusion is misaligned with the plug-in; when the two main connecting pipes are plugged in, the protrusion of one main connecting pipe is inserted into the recess of the other main connecting pipe.

[0011] By adopting the above technical solution, the insertion and matching of the protrusion and the recess makes it difficult for the two main connecting pipes to rotate relative to each other after insertion and matching, thereby further improving the stability between the main connecting pipes.

[0012] Optionally, the water distribution head includes an outer shell, an inner shell, and a limiting member. One end of the outer shell is connected to the main connecting pipe and cooperates with the opening and closing member. The inner shell is disposed in the outer shell, and the inner shell and the outer shell together enclose an assembly space for inserting an external pipe, so that the external pipe can be connected to the main connecting pipe through the inner shell. The limiting member is disposed between the outer shell and the inner shell and has deformation capability. The limiting member limits the external pipe by pressing against the external pipe inserted into the assembly space.

[0013] By adopting the above technical solution, the external pipe is inserted into the assembly space and held in place by the limiting component, so as to be installed on the water distributor head and connected to the main connecting pipe at the same time. When the opening and closing component opens the water distributor head, the water flow in the main connecting pipe can be diverted from the outer shell to the external pipe.

[0014] Optionally, the water distribution head further includes a pressure member disposed between the outer shell and the inner shell, for the external pipe inserted into the assembly space to abut against.

[0015] By adopting the above technical solution, the pressure member is used to abut against the external pipe, thereby limiting the insertion position of the external pipe.

[0016] Optionally, both the inner wall of the outer shell and the outer wall of the inner shell are provided with sealing rings for abutting against the external pipe.

[0017] By adopting the above technical solution, the sealing ring can seal and stop water from external pipes, reducing the occurrence of water leakage.

[0018] Optionally, a valve seat is rotatably connected to the inner housing to open and close the inner housing, and a linkage component is provided between the valve seat and the inner housing, so that when the external pipe is fitted onto the inner housing, the linkage component drives the valve seat to rotate to open the inner housing, and when the inner housing is separated from the external pipe, the linkage component drives the valve seat to rotate to close the inner housing.

[0019] By adopting the above technical solution, when the external pipe is fitted with the inner shell, the valve seat opens the inner shell through the linkage component, so that the external pipe is connected to the valve seat. When the external pipe leaves the inner shell, the valve seat closes the inner shell, so as to prevent water from spraying out of the water distribution head if the external pipe is pulled out without closing the water distribution head with the opening and closing component.

[0020] Optionally, the linkage component includes The valve seat has two sliding rods, which slide along the same straight line on opposite sides of the valve seat. The valve seat has mounting cavities for the sliding rods to slide. The ends of the two sliding rods that are far apart from each other slide through opposite sides of the inner housing. The inner housing has through holes for the sliding rods to pass through. An elastic element, disposed in the mounting cavity of the valve seat, acts on the sliding rods, causing the two sliding rods to tend to move away from each other; and A pusher is disposed on the sliding rod and cooperates with the valve seat. The valve seat is provided with a pusher groove inclined around the sliding rod in the circumferential direction for the pusher to slide, so that the valve seat is driven to rotate when the sliding rod moves. The sliding rod has a guide surface at the end away from the elastic element. When the external pipe is fitted onto the inner housing, the external pipe pushes the two sliding rods to move closer to each other through the guide surface, so that the valve seat rotates to open the inner housing. When the external pipe leaves the inner housing, the elastic element pushes the two sliding rods to move further away from each other, so that the valve seat rotates to close the inner housing.

[0021] By adopting the above technical solution, when the external pipe pushes the sliding rod through the guide surface, the sliding rod moves. Through the cooperation of the pushing component and the pushing groove, the sliding rod causes the valve seat to rotate around the sliding rod, thereby enabling the valve seat to rotate to the state of opening or closing the inner shell.

[0022] Optionally, the inner housing is provided with a travel portion at the inner wall of the through hole, and the outer wall of the sliding rod is provided with a travel groove for the travel portion to slide. When the travel portion abuts against the end of the sliding rod near the elastic member at the travel groove, the portion of the sliding rod having the guide surface enters the space between the outer housing and the inner housing.

[0023] By adopting the above technical solution, the cooperation between the stroke section and the stroke groove can limit and guide the movement of the sliding rod.

[0024] Optionally, a first magnetic attractor is provided on the inner wall of the inner housing, and a second magnetic attractor is provided on the valve seat for attracting the first magnetic attractor. When the valve seat closes the inner housing, the first magnetic attractor and the second magnetic attractor move closer to each other and attract each other.

[0025] By adopting the above technical solution, the attraction between the first magnetic element and the second magnetic element can improve the stability of the valve seat when closing the inner shell, enabling the valve seat to resist the impact force from the water flow in the main connecting pipe.

[0026] In summary, this application has the following beneficial effects: The various manifold modules are connected and assembled into one unit via a main connecting pipe, allowing for the selection of the number of water distribution heads to form any number of channels, thus improving the applicability of the manifold.

[0029] The following is in conjunction with the appendix Figure 2-11 This application will be described in further detail.

[0030] Example 1: This application discloses a water distribution manifold. (Refer to...) Figure 1 and Figure 2 The water distribution unit includes multiple water distribution unit modules 3 that are connected sequentially. Each water distribution unit module 3 includes a main connecting pipe 4 and a water distribution head 5. There is one main connecting pipe 4 and one water distribution head 5. The water distribution head 5 is installed and connected to the main connecting pipe 4. The water distribution unit modules 3 are connected through the main connecting pipe 4 in the water distribution unit modules 3.

[0031] When using the water manifold, connect one end of the water manifold module 3 (main connecting pipe 4) to the water source pipe, and close the other end of the main connecting pipe 4. Connect each water distributor 5 to an external pipe 33. This allows the water manifold to distribute water from the water source through the main connecting pipe 4 to the external pipes 33 connected to each water distributor 5 when used for water distribution. Conversely, when used for water distribution, the water in the external pipes 33 is collected through each water distributor 5 to the main connecting pipe 4, and then collected from the main connecting pipe 4 back to the water source.

[0032] Reference Figure 3 and Figure 4Regarding the main connecting pipe 4, it is a circular pipe extending through both ends, with the water distributor 5 installed on the side wall of the main connecting pipe 4. A connector 7 is integrally formed on the end wall of one end of the main connecting pipe 4, and a slot 8 is provided on the inner wall of the opposite end of the main connecting pipe 4 for the connector 7 to be inserted into. The connector 7 is a circular pipe coaxial with the main connecting pipe 4, with its inner diameter matching that of the main connecting pipe 4, and its outer diameter being smaller than that of the main connecting pipe 4. The slot 8 is coaxially located on the inner wall of the main connecting pipe 4, and its inner diameter matches that of the connector 7.

[0033] When multiple main connecting pipes 4 are spliced ​​together in sequence, between any two adjacent main connecting pipes 4, the connector 7 of one main connecting pipe 4 is inserted into the slot 8 of the other main connecting pipe 4, so that the two adjacent main connecting pipes 4 are coaxially arranged and interconnected.

[0034] Reference Figure 3 and Figure 4 To prevent the main connecting pipes 4 from easily separating after splicing, each main connecting pipe 4 is provided with a limiting member 9 in the slot 8 to limit the insertion of the connector 7 into the slot 8. The limiting member 9 includes a limiting ring 91 and a water-stop ring 92. The main connecting pipe 4 has a first receiving groove on the inner wall of the slot 8 for the limiting ring 91 to be placed coaxially with the main connecting pipe 4. The main connecting pipe 4 also has a second receiving groove on the inner wall of the slot 8 for the water-stop ring 92 to be placed coaxially with the main connecting pipe 4. The limiting ring 91 and the water-stop ring 92 are distributed along the axial direction of the main connecting pipe 4. In this embodiment, there are two water-stop rings 92 distributed along the axial direction of the main connecting pipe 4.

[0035] The limiting ring 91 is circular in shape and made of elastic rubber or plastic. It has a notch to accommodate deformation. The limiting ring 91 flares outwards along the direction away from the vertical center line of the main connecting pipe 4. One end of the limiting ring 91 away from the vertical center line of the main connecting pipe 4 is located in the first receiving groove, while the other end extends into the slot 8. The minimum inner diameter of the limiting ring 91 is smaller than the inner diameter of the slot 8. A limiting ring groove 25, which mates with the limiting ring 91, is formed on the outer wall of the connector 7 along its circumference.

[0036] The inner diameter of the water-stop ring 92 is smaller than the outer diameter of the connector 7, and the material of the water-stop ring 92 is rubber-like. During the process of inserting the connector 7 into the limiting ring 91, the limiting ring 91 is compressed and deformed, and the water-stop ring 92 is also compressed and deformed. When the connector 7 is fully inserted into the slot 8, the limiting ring groove 25 is opposite to the limiting ring 91, and the end of the limiting ring 91 with the smaller inner diameter at both ends is engaged in the limiting ring groove 25 to limit the connector 7, and the water-stop ring 92 is tightly held against the outer wall of the connector 7, making it difficult for the connector 7 to fall out of the slot 8 and improving the sealing between the two adjacent main connecting pipes 4.

[0037] Reference Figure 3 and Figure 5 Furthermore, a protrusion 10 is fixed on the end face of the main connecting pipe 4 at the end with the slot 8, and a recess 11 corresponding to the protrusion 10 is provided on the end face of the main connecting pipe 4 away from the protrusion 10. The protrusion 10 is cylindrical with its axis parallel to and separate from the axis of the main connecting pipe 4, and the recess 11 is groove-shaped.

[0038] During the splicing process of two adjacent main connecting pipes 4 through the connector 7 and the slot 8, the protrusion 10 on one main connecting pipe 4 is inserted into the recess 11 on the other main connecting pipe 4, and the protrusion 10 does not interfere with the connector 7, so that the two adjacent main connecting pipes 4 are not easy to rotate relative to each other after splicing, thereby improving the stability of the main connecting pipes 4.

[0039] Reference Figure 4 and Figure 6 Regarding the water distributor 5, the water distributor 5 includes an outer shell 51, an inner shell 52, a pressing member 54, and a release member 53. The outer shell 51 is a cylindrical shape with both ends open. One end of the outer shell 51 is fixed in and communicates with the main connecting pipe 4, and the other end of the outer shell 51 extends outside the main connecting pipe 4, with the extension axis of the outer shell 51 perpendicular to the axis of the main connecting pipe 4. The inner shell 52 is cylindrical and located inside the outer shell 51, communicating with the connecting pipe through the outer shell 51. The top end of the inner shell 52 is close to the main connecting pipe 4, and the top end of the inner shell 52 has an outwardly protruding annular protrusion. The inner shell 52 is interference-fitted to the top end of the portion of the outer shell 51 located outside the main connecting pipe 4 through the annular protrusion, so that the inner shell 52 is coaxially installed in the outer shell 51.

[0040] The pressing member 54 is annular and is coaxially sleeved against the top outer wall of the inner shell. The outer wall of the pressing member 54 abuts against the inner wall of the outer shell 51, and the pressing member 54 is located below the annular protrusion at the top of the inner shell 52 to prevent the inner shell 52 from disengaging from the pressing member 54.

[0041] The inner wall of the outer shell 51, the bottom wall of the pressing member 54, and the outer wall of the inner shell 52 together form an assembly space 12. The assembly space 12 is used for the coaxial insertion of the external pipe 33 from bottom to top, so that the external pipe 33 is assembled into the outer shell 51. When the external pipe 33 moves in the assembly space 12 and abuts against the bottom end of the pressing member 54, it reaches the assembly position. At this time, the external pipe 33 is connected to the inner shell 52, which is also connected to the main connecting pipe 4. In addition, the external pipe 33 is a rigid pipe and its inner diameter is the same as the outer diameter of the inner shell 52. Reference Figure 4 and Figure 6The release element 53 is installed at the bottom of the outer shell 51 and is made of metal or plastic with a certain elastic deformation capability. When the external pipe 33 is inserted into the outer shell 51, it squeezes the release element 53 and deforms it. When the external pipe 33 reaches the assembly position, the release element 53 presses the external pipe 33 against it with its own restoring elastic force to limit the external pipe 33 and make it difficult for the external pipe 33 to come out of the outer shell 51.

[0042] Reference Figure 4 and Figure 6 Specifically, the limiting component 53 includes an operating ring 531, a connecting ring 532, and a limiting seat 533 connected in sequence. The operating ring 531 and the connecting ring 532 are both annular and integrally formed. The inner diameters of the operating ring 531 and the connecting ring 532 are approximately equal to the outer diameter of the external pipe 33, and the outer diameter of the connecting ring 532 is smaller than the outer diameter of the operating ring 531. Multiple limiting seats 533 are evenly spaced along the circumference of the connecting ring 532, and there is a space for movement between adjacent limiting seats 533.

[0043] An installation space 26 is formed on the inner wall of the outer casing 51 to accommodate the connecting ring 532 and the limiting seat 533. The installation space 26 is connected to the assembly space 12. A retaining ring 27 is coaxially fixed to the outer casing 51 at the installation space 26. The bottom of the retaining ring 27 has an upwardly extending movable groove 28. The top of the limiting seat 533 enters the movable groove 28 and abuts against the side wall of the movable groove 28. The side wall of the movable groove 28 and the limiting seat 533 abuts is inclined downwards and gradually approaches the central axis of the outer casing 51. Limiting teeth 29 are distributed on the side of each limiting seat 533 facing the assembly space 12.

[0044] When the external pipe 33 is separated from the outer shell 51, the limiting seat 533 is in its natural state, and the limiting teeth 29 enter the assembly space 12. When the external pipe 33 is inserted into the outer shell 51, it abuts against the limiting teeth 29, causing the limiting teeth 29 to move towards the installation space 26, so as to squeeze the limiting seat 533 into the movable groove 28 and deform the limiting seat 533. Thus, the self-resetting elastic force of the limiting seat 533 drives the limiting teeth 29 on the limiting seat 533 to press against the external pipe 33.

[0045] When it is necessary to pull the external pipe 33 out of the outer casing 51, push the operating ring 531 towards the main connecting pipe 4. The operating ring 531 drives each limiting seat 533 to move towards the main connecting pipe 4 through the connecting ring 532. The limiting seat 533 is deformed by the guide of the inclined inner wall of the movable groove 28, causing the limiting teeth 29 to move away from the external pipe 33, thereby reducing the clamping force of the limiting teeth 29 on the external pipe 33, so that the external pipe 33 can be pulled out of the outer casing 51.

[0046] Reference Figure 4 and Figure 6 Furthermore, to improve the sealing between the outer casing 51 and the external pipe 33, sealing rings 14, made of rubber, are embedded in the inner wall of the outer casing 51 and the outer wall of the inner casing 52. After the external pipe 33 is inserted into the assembly space 12, the sealing rings 14 at the opposite locations of the outer casing 51 and the assembly space 12 abut against the outer wall of the external pipe 33, and the sealing rings 14 at the opposite locations of the inner casing 52 and the assembly space 12 abut against the inner wall of the external pipe 33, to prevent water from leaking out of the assembly space 12. In addition, sealing rings 14 for pressing against the pressing member 54 are provided at the locations where the inner wall of the outer casing 51 and the pressing member 54 are opposite, and the sealing rings 14 are jointly enclosed by the annular protrusion of the inner casing 52 and the outer casing 51, to further improve the waterproof sealing effect between the inner casing 52 and the outer casing 51.

[0047] In this embodiment, two sealing rings 14 for abutting against the external pipe 33 are provided on the inner shell 52 along the axial direction of the inner shell 52, one sealing ring 14 for abutting against the pressing member 54 is provided on the inner shell 52, one sealing ring 14 for abutting against the external pipe 33 is provided on the outer shell 51, and one sealing ring 14 for abutting against the pressing member 54 is provided on the outer shell 51.

[0048] Reference Figure 4 and Figure 5 In addition, in order to control the distribution of water flow to the water distribution head 5, an opening and closing element 6 is provided between the main connecting pipe 4 and the outer casing 51. The opening and closing element 6 is used to control the opening or closing of the channel connecting the outer casing 51 and the main connecting pipe 4. Specifically, the part of the top of the outer casing 51 extending into the main connecting pipe 4 forms a connecting port 13, which is connected to the main connecting pipe 4.

[0049] The opening / closing component 6 includes a plug 61, a valve stem 62, and a cap 63. The cap 63 is installed on the pipe wall opposite to the main connecting pipe 4 and the connecting port 13. The valve stem 62 is threaded through the cap 63 in a direction perpendicular to the axis of the main connecting pipe 4. The plug 61 is conical with its tip facing the connecting port 13 and is fixed to the part of the valve stem 62 located inside the main pipe connection. Both the valve stem 62 and the plug 61 are coaxial with the connecting port 13. When the valve stem 62 moves closer to the connecting port 13, it can cause the plug 61 to seal the connecting port 13, thereby isolating the outer casing 51 from the main connecting pipe 4. When the valve stem 62 moves away from the connecting port 13, it can cause the plug 61 to leave the outer casing 51 to open the connecting port 13, thereby connecting the outer casing 51 with the main connecting pipe 4.

[0050] The implementation principle of a water distribution manifold according to this application embodiment is as follows: the required number of water distribution manifold modules 3 is determined based on demand, and the main connecting pipes 4 in each water distribution manifold module 3 are sequentially inserted into slots 8 via connectors 7, and the connectors 7 are restricted from leaving the slots 8 by limiting members 9 in the slots 8. After the water distribution manifold modules 3 are assembled, each external pipe 33 is inserted into the assembly space 12 of each water distribution head 5. The external pipes 33 inserted into the assembly space 12 are limited by sealing rings 14 and release limiting members 53, so that the external pipes 33 can be quickly assembled onto the water distribution head 5.

[0051] Example 2: When the water collector is used for water distribution, hot water usually flows through the main connecting pipe 4. However, when the operator pulls out the external pipe 33 from the water distribution head 5, there may be a situation where the connection port of the outer casing 51 is not closed before pulling out the external pipe 33, causing the hot water in the main connecting pipe 4 to spray out from the water distribution head 5, which may endanger the personal safety of the operator. In order to improve this situation, this application embodiment makes further improvements based on embodiment one.

[0052] This application discloses a water distribution device, which differs from Embodiment 1 in that, referring to... Figure 7 A valve seat 15 is rotatably connected to one end of the inner housing 52 away from the main connecting pipe 4, and a linkage assembly 16 for driving the valve seat 15 to rotate is provided between the valve seat 15 and the inner housing 52.

[0053] When the external pipe 33 is separated from the inner shell 52, the linkage component 16 drives the valve seat 15 to rotate and close the inner shell 52 to prevent water from spraying out of the inner shell 52; when the external pipe 33 is inserted into the assembly space 12, that is, when the external pipe 33 is sleeved on the outer wall of the inner shell 52, the external pipe 33 cooperates with the linkage component 16 to drive the valve seat 15 to rotate and open the inner shell 52, so that the water in the main connecting pipe 4 can flow into the external pipe 33 through the inner shell 52.

[0054] Reference Figure 8 Specifically, the valve seat 15 is disc-shaped, and the edges of the two opposite sides of the valve seat 15 are chamfered. The middle part of the valve seat 15 protrudes towards the two opposite sides to form a mounting part 30. The length of the mounting part 30 extends along the axial direction of the valve seat 15, and the mounting part 30 is a cylindrical shape with a hollow interior and through ends. The axis of the mounting part 30 is perpendicular to the axis of the valve seat 15, and the hollow part of the mounting part 30 forms a mounting cavity 17.

[0055] Reference Figure 7 and Figure 9The linkage assembly 16 includes a sliding rod 161, an elastic element 162, and a pushing element 163. There are two sliding rods 161, coaxially arranged with the mounting portion 30. Both sliding rods 161 slide within the mounting cavity 17 and are located at opposite ends of the mounting portion 30. The elastic element 162 is a spring installed in the mounting cavity 17, located between the two sliding rods 161. The opposite ends of the elastic element 162 are connected to the adjacent ends of the two sliding rods 161. The elastic force of the elastic element 162 drives the two sliding rods 161 to slide in a direction away from each other.

[0056] Reference Figure 9 and 10 Each pusher 163 corresponds to a sliding rod 161. The pusher 163 is cylindrical and fixed to the outer wall of the corresponding sliding rod 161 near the elastic member 162. The axis of the pusher 163 is perpendicular to the axis of the sliding rod 161, and a chamfer is formed at the edge of the pusher 163 away from the sliding rod 161. The mounting part 30 has a push groove 19 on the inner wall of the mounting cavity 17 that corresponds to each pusher 163. The push groove 19 extends obliquely away from the elastic member 162 in the circumferential direction of the mounting part 30, and the pusher 163 is inserted into the push groove 19 and slides along the extension direction of the push groove 19.

[0057] The inner housing 52 has two through holes 18 at the point where it abuts against the two sealing rings 14 of the external pipe 33. These through holes 18 correspond to the limiting teeth 29 in the limiting seat 533. Each of the two through holes 18 corresponds to one of the two sliding rods 161, allowing the corresponding sliding rod 161 to slide through the inner housing 52, with the axis of the sliding rod 161 perpendicular to the axis of the inner housing 52. The valve seat 15 is installed in the inner housing 52 through the cooperation of the sliding rod 161. The outer circumference of the valve seat 15 is covered with an elastic rubber layer so that the outer diameter of the valve seat 15 is approximately equal to the inner diameter of the inner housing 52, allowing the valve seat 15 to rotate within the inner housing 52.

[0058] Reference Figure 8 and Figure 9 The end of the sliding rod 161 away from the elastic member 162 is formed into a hemispherical shape, coaxial with the sliding rod 161 and with the same diameter as the sliding rod 161. The arc surface of the hemispherical shape forms a guide surface 20. The inner housing 52 has a downwardly extending stroke portion 21 fixed on the inner top surface of the through hole 18. The stroke portion 21 is block-shaped. A stroke groove 22 is provided on the outer wall of the sliding rod 161 for the stroke portion 21 to slide. The extension direction of the stroke groove 22 is parallel to the axial direction of the sliding rod 161, and the stroke groove 22 passes through the end of the sliding rod 161 away from the elastic member 162.

[0059] Reference Figure 7 and Figure 9When the external pipe 33 is separated from the inner shell 52, the elastic force of the elastic element 162 drives the two sliding rods 161 to move away from each other. The guide surface 20 of the sliding rod 161 protrudes from the outer wall of the inner shell 52. At this time, the stroke part 21 abuts against the inner end wall of the stroke groove 22 near the end of the elastic element 162, and the pusher 163 abuts against the inner wall of the push groove 19 away from the end of the elastic element 162. The elastic element 162 is in a compressed state. At the same time, the axis of the valve seat 15 coincides with the axis of the inner shell 52, and the valve seat 15 closes the inner shell 52.

[0060] Reference Figure 9 and Figure 11 During the process of inserting the external pipe 33 into the assembly space 12 and fitting it onto the outer wall of the inner housing 52, the external pipe 33 first abuts against the guide surface 20. Then, the external pipe 33 pushes the two sliding rods 161 towards each other through the arc of the guide surface 20. At the same time, the valve seat 15 rotates through the cooperation of the pushing member 163 and the pushing groove 19. When the end of the external pipe 33 has completely passed the sliding rod 161, the ends of the two sliding rods 161 that are far apart are respectively housed in the corresponding through holes 18, and the pushing member 163 abuts against the inner wall of the pushing groove 19 near the elastic member 162. The elastic member 162 is in a compressed state. At the same time, the axis of the valve seat 15 is perpendicular to the axis of the inner housing 52, and the valve seat 15 opens the inner housing 52.

[0061] Reference Figure 10 Furthermore, a first magnetic attractor 23 is fixed on the inner housing 52, and a second magnetic attractor 24 is embedded on one side of the valve seat 15. Both the first magnetic attractor 23 and the second magnetic attractor 24 are magnets. When the valve seat 15 closes the inner housing 52, the side of the valve seat 15 with the second magnetic attractor 24 faces and approaches the first magnetic attractor 23. At this time, the first magnetic attractor 23 and the second magnetic attractor 24 attract each other to improve the stability of the valve seat 15.

[0062] Reference Figure 8 and Figure 9 Furthermore, in order to improve the sealing effect of the valve seat 15, the valve seat 15 is cut at the two ends of the mounting part 30 that are far apart to form a rotating plane 31. The inner wall of the inner housing 52 has an inward protrusion of an abutting platform 32 at the through hole 18. The sliding rod 161 passes through the abutting platform 32. When the valve seat 15 rotates, the rotating plane 31 abuts against the abutting platform 32 to improve the sealing between the inner housing 52 and the valve seat 15.

[0063] The implementation principle of a water distribution device according to an embodiment of this application is as follows: When the external pipe 33 is pulled out of the water distribution head 5, the elastic element 162 drives the two sliding rods 161 to move away from each other, thereby causing the valve seat 15 to rotate to the state of closing the inner shell 52. When the external pipe 33 is inserted into the water distribution head 5, the external pipe 33 presses the end of the sliding rod 161 into the through hole 18, and the sliding rod 161 moves to drive the valve seat 15 to rotate to the state of opening the inner shell 52.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
