[0032] An electrically controlled water distributor comprises a water inlet valve body 1, a plurality of water outlet valve bodies 2 and a plurality of first pipeline structures 26; the water inlet valve body 1 is provided with a water inlet 11 and a plurality of water outlet pipe openings 12, the plurality of water outlet pipe openings 12 are interconnected with the water inlet 11, the side wall of the water outlet pipe opening 12 is provided with branch water outlet pipe openings 13, the plurality of water outlet pipe openings 12 are respectively interconnected with the plurality of water outlet valve bodies 2 in a one-to-one manner; the plurality of branch water outlet pipe openings 13 are respectively connected with the plurality of first pipeline structures 26 in a one-to-one manner;

[0033] The first pipeline structure 26 includes an inlet pipe 261, an outlet pipe 262 and a connecting pipe 265. The water inlet end of the inlet pipe 261 is connected to the branch water outlet pipe 13, the water outlet end of the inlet pipe 261 and the water inlet end of the outlet pipe 262 are respectively connected to the connecting pipe 265, and an electromagnetic reversing valve 263 is provided between the outlet pipe 262 and the connecting pipe 265. The electromagnetic reversing valve 263 is used to control the conduction between the outlet pipe 262 and the connecting pipe 265, and control the conduction between the inlet pipe 261 and the connecting pipe 265;

[0034] The outlet valve body 2 comprises a valve body shell 21, a sealing rubber bladder 22, a sealing member 23 and a bracket 24. The valve body shell 21 is provided with a cavity with two ends passing through it along its axial direction. The valve body shell 21 is provided with a branch water inlet 25, and the branch water inlet 25 is connected to the connecting pipe 265; the sealing rubber bladder 22 is a deformable structure, and the sealing rubber bladder 22 is installed in the cavity. The outer periphery of the sealing rubber bladder 22 and the inner wall of the cavity form a sealed control cavity 30, and the control cavity 30 is connected to the branch water inlet 25; the sealing rubber bladder 22 is a deformable structure, and the sealing rubber bladder 22 is installed in the cavity. The outer periphery of the sealing rubber bladder 22 and the inner wall of the cavity are surrounded to form a sealed control cavity 30, and the control cavity 30 is connected to the branch water inlet 25. The interior of the sealing rubber bladder 22 is penetrated by a flow channel with two ends passing through along its axial direction. The bracket 24 is installed in the interior of the sealing rubber bladder 22 and is used to support the flow channel of the sealing rubber bladder 22. The sealing member 23 is installed in the flow channel through the bracket 24. When the sealing rubber bladder 22 is not deformed, the inner wall of the sealing rubber bladder 22 fits and seals with the outer periphery of the sealing member 23, and the flow channel is not conductive. When the sealing rubber bladder 22 is deformed, the inner wall of the sealing rubber bladder 22 does not fit with the outer periphery of the sealing member 23, and the flow channel is conductive.

[0035] The water inlet valve body 1 is the water inlet part of the electric control water distributor, including a plurality of water outlets 12, such as Figures 1 to 3 As shown, there are three water outlet pipes 12, each of which is provided with a corresponding water outlet valve body 2 connected thereto, and there are also three water outlet valve bodies 2. There are also branch water outlet pipes 13 on the side walls of the water outlet pipes 12. After the water flows into the water inlet valve body 1 from the water inlet 11, it is diverted to each water outlet pipe 12 and flows to the water end valve body 2.

[0036] like Figure 5 As shown, the water outlet valve body 2 is a hollow cylinder as a whole. When water is not needed, the electromagnetic reversing valve 263 blocks the water outlet pipe 262 and the connecting pipe 265, and the water at the water outlet pipe 12 flows from the water inlet pipe 261 to the connecting pipe 265, and then enters the control chamber 30 from the branch water inlet 25. The water pressures of the inner cavity and the outside of the control chamber 30 are equal, the sealing rubber bladder 22 does not deform, and the inner wall of the sealing rubber bladder 22 remains in contact with the sealing element 23, so that the flow channel of the water outlet valve body 2 is closed, and the water at the water outlet pipe 12 is prevented from flowing to the outside through the cavity in the valve body shell 21.

[0037] like Figure 6As shown, when water needs to be discharged, the electromagnetic reversing valve 263 is operated to make the water outlet pipe 262 and the connecting pipe 265 conductive, and the water inlet pipe 261 and the connecting pipe 265 blocked, so that the pressure in the control chamber 30 is not equal to the water supply pressure provided by the water outlet pipe port 12. Under the action of the water supply pressure, the sealing rubber bladder 22 is deformed by the impact of the water at the water outlet pipe port 12, so that the water inside the control chamber 30 flows out from the water inlet 25 and is discharged through the water outlet pipe 262. The sealing rubber bladder 22 does not fit the sealing component 23 during the deformation stage. At this time, the water outlet end valve body 2 is in a flow state, so that the water at the water outlet pipe port 12 flows to the outside through the cavity in the valve body shell 21.

[0038] According to the above scheme, the design of the electromagnetic reversing valve 263 enables the conduction state between the water outlet pipe 262 and the connecting pipe 265 to be remotely and flexibly controlled, thereby improving the intelligence and automation level of the water distributor. The sealing rubber liner 22 is a deformable structure, and the sealing rubber liner 22 can control the conduction state of the flow channel through the water pressure difference, which not only ensures the sealing performance, but also realizes the flexible adjustment of the water flow. The bracket 24 of the electric-controlled water distributor provides stable support and structural stability, reducing the risk of damage or leakage caused by vibration. Through a simple structural design, remote and precise control of each water outlet of the water distributor is achieved, which reduces the production cost and maintenance difficulty of the equipment compared with the existing technology.

[0039] Furthermore, it also includes a second pipeline structure 28, and the side pipe wall of the water outlet pipe port 12 is also provided with a second branch water outlet pipe port 282, and the second branch water outlet pipe port 282 is connected one-to-one with the second pipeline structure 28, and the second pipeline structure 28 includes a second water inlet pipe 283, a second water outlet pipe 284 and a second connecting pipe 285, and the water outlet end of the second water inlet pipe 283 and the water inlet end of the second water outlet pipe 284 are respectively connected to the second connecting pipe 285, and the valve body shell 21 is also provided with a second branch water inlet port 281, and the connection between the second connecting pipe 285, the second water outlet pipe 284 and the second water inlet pipe 283 is provided with a manual reversing valve 286, and the manual reversing valve 286 is used to manually control the conduction between the second water outlet pipe 284 and the second connecting pipe 285, and to control the conduction between the second water inlet pipe 283 and the second connecting pipe 285.

[0040] Specifically, Figure 2 As shown, similar to the first pipeline structure 26, the second pipeline structure 28 includes a second water inlet pipe 283, a second water outlet pipe 284 and a second connecting pipe 285. The electromagnetic reversing valve 263 is automatically controlled by electric pulses, providing higher precision and flexibility. Compared with the electromagnetic reversing valve 263, the manual reversing valve 286 is more stable and safer, and relies on the direct intervention of the operator to change the state of the valve.

[0041] When water is not needed, the manual reversing valve 286 is manually operated to block the second water outlet pipe 284 and the second connecting pipe 285, and the second water inlet pipe 283 and the second connecting pipe 285 are connected, so that the water flows from the second branch water outlet pipe 282 to the second connecting pipe 285, and then enters the control chamber 30 from the second branch water inlet 281. The water pressures of the inner cavity and the outside of the control chamber 30 are equal, the sealing rubber bladder 22 does not deform, and the inner wall of the sealing rubber bladder 22 remains in contact with the sealing element 23, so that the flow channel of the water outlet valve body 2 is closed, and the water at the water outlet pipe 12 is prevented from flowing to the outside through the cavity in the valve body shell 21.

[0042] When water needs to be discharged, the manual reversing valve 286 is operated to make the second water outlet pipe 284 and the second connecting pipe 285 conductive, and the second water inlet pipe 283 and the second connecting pipe 285 blocked, so that the pressure in the control chamber 30 is not equal to the water supply pressure provided by the water outlet pipe 12. Under the action of the water supply pressure, the sealing rubber bladder 22 is deformed by the water impact of the water outlet pipe 12, so that the water inside the control chamber 30 flows out of the control chamber 30 and is discharged through the second water outlet pipe 284. The sealing rubber bladder 22 does not fit the sealing member 23 during the deformation stage. At this time, the water outlet valve body 2 is in a flow state, so that the water at the water outlet pipe 12 flows to the outside through the cavity in the valve body shell 21. The manual reversing valve 286 and the electromagnetic reversing valve 263 are used in combination, and the most suitable control method can be selected according to the specific application requirements. The electromagnetic reversing valve 263 can be used in the part that requires high precision and automation, and the manual reversing valve 286 can be used in the part that requires high stability and simple operation.

[0043] Furthermore, a check valve 264 is provided between the water inlet end of the water inlet pipe 261 and the water outlet pipe port 13 , and the check valve 264 is used to prevent the water in the water inlet pipe 261 from flowing back to the water inlet end valve body 1 .

[0044] Specifically, during use, water in the water inlet pipe 261 may flow back to the water inlet valve body 1, which may cause unnecessary water pressure changes or affect the stability and working efficiency of the entire system. The backflow may cause unexpected pressure increase in the pipeline and valve body, which may exceed the design specifications and cause damage or failure of equipment or pipeline components. The installation of the check valve 264 effectively prevents this from happening, ensuring the safety and reliability of the system when not in use.

[0045] Preferably, the water outlet pipe 262 is further provided with a valve, and the water outlet pipe 262 is provided with a water flow indicator 2621 , and the water flow indicator 2621 is used to control the opening and closing of the valve of the water outlet pipe 262 .

[0046] Specifically, when water is discharged, the water inside the control chamber 30 needs to be discharged, and the water flows out from the connecting pipe 265 through the water outlet pipe 262. The water flow indicator 2621 can detect the water flow in the water outlet pipe 262, such as whether there is water flowing through. When the water flow indicator 2621 detects that water needs to be discharged, it can send a signal to the valve to open the valve to allow water to flow through the water outlet pipe 262. When the pressure in the control chamber 30 is the same as that in the outside world, the water flow is not enough to reach the water flow indicator 2621, and the water flow indicator 2621 can close the valve to stop the water flow, thereby controlling the start and end of the drainage operation, improving the automation of the system, and reducing the need for manual intervention.

[0047] Preferably, the bracket 24 includes two sub-brackets and a connecting shaft 27, the sealing member 23 is sleeved on the middle part of the connecting shaft 27, the two sub-brackets are respectively installed at the two ends of the connecting shaft 27, the sub-bracket includes a base frame 241, a fixing member 243 and at least two radiating strips 242, the base frame 241 is connected to the fixing member 243 through the radiating strips 242, forming a platform structure with the fixing member 243 as the top, the two platform structures are symmetrically arranged on the connecting shaft 27, and the edge of the base frame 241 is sealed and fitted with the inner wall of the sealing rubber bladder 22.

[0048] Specifically, Figure 4 As shown, the base frame 241 is a circular ring, the sealing member 23 is a sealing ring, and the fixing member 243 is connected to the base frame 241 through the radiation strips 242, thereby ensuring the stable structure of the sub-bracket. The two fixing members 243 are arranged through the connecting shaft 27 and are installed at the two ends of the sealing member 23 in opposite directions. The connecting shaft 27 passes through the fixing member 243 and the sealing member 23, thereby achieving the purpose of fixing the sub-bracket by the connecting shaft 27, enhancing the stability when water flows between the base frame 241 and the radiation strips 242 and when the sealing rubber bladder 22 and the bracket 24 are fitted, ensuring that the liquid can smoothly pass through the bracket 24, thereby achieving the normal operation and flow control of the water distributor, and the number of the radiation strips 242 is determined according to the bearing capacity to be achieved by the bracket 24. Under a certain bearing capacity, if the radiation strips 242 become thinner, the number of the radiation strips 242 can be appropriately increased to achieve the purpose of coordinating the bearing capacity of the bracket 24, and at the same time, the water outlet of the cavity will not be affected by too many radiation strips 242.

[0049] Furthermore, it also includes a split pin 271, the outer surface of the connecting shaft 27 is provided with threads, the connecting shaft 27 is connected to the fixing nut 272 by threads, and the two fixing members 243 are fixed to the two ends of the sealing member 23;

A fixing hole is provided on the connecting shaft 27, and the axis of the fixing hole is perpendicular to the axis of the connecting shaft. The cotter pin 271 is passed through the nut groove and the fixing hole of the fixing nut 272 to prevent the threaded part of the fixing nut 272 on the connecting shaft 27 from rotating, thereby ensuring the position stability of the fixing nut 272. Even if a rotational force is applied to the connecting shaft 27, the fixing nut 272 will not rotate therewith.

[0052] Furthermore, it also includes a water outlet cavity valve body 3, the water outlet cavity valve body 3 is connected to the valve body shell 21, the water outlet cavity valve body 3 is communicated with the water outlet end valve body 2, and the water outlet cavity valve body 3 is provided with threads.

[0053] Specifically, the water outlet chamber valve body 3 and the water outlet end valve body 2 are interconnected, and water flows from the water outlet end valve body 2 to the water outlet chamber valve body 3.
