[0026] like Figure 1-7As shown, the technical solution of the present application provides a single-inlet multi-outlet switching solenoid valve, including: a valve bottom shell 1, which includes a water supply cylinder 11, the cylinder body of the water supply cylinder 11 is connected in series with a plurality of diversion cylinder shells 13 along the axial direction, the top of the diversion cylinder shell 13 is provided with a socket 130, one end of the water supply cylinder 11 is connected with a water supply pipe port 111, the side wall of the diversion cylinder shell 13 extends outward with a drainage pipe port 112, and the drainage pipe port 112 extends to the inside of the diversion cylinder shell 13 with an upper curved pipe section 113, the internal space of the water supply cylinder 11 is the water supply chamber 101, the internal area of ​​the pipe along the drainage pipe port 112 to the upper bend pipe section 113 is the drainage chamber 102, and the space in the diverter shell 13 except the upper bend pipe section 113 is the socket cavity 103, and the socket cavity 103 is connected with the water supply chamber 101 space; multiple electromagnetic valve cores 2, which are a cylinder shell structure, and the electromagnetic valve core 2 has an opening and closing component 22, and the opening and closing component 22 includes two states of opening and closing The solenoid valve core 2 is matched and inserted into each socket cavity 103 through the socket 130, and the opening and closing component 22 blocks the upper bend pipe section 113. The solenoid valve core 2 is connected to an electromagnetic control device 3 to change the state of the opening and closing component. In the present technical scheme, multiple diversion cylinder shells 13 are connected to a single water supply cylinder 11, so that each drainage pipe outlet 112 can discharge water independently. The diversion cylinder shell 13 and the water supply cylinder 11 are integrated to avoid the risk of leakage. The diversion cylinder shell 13 can be arranged in a finished shape along the water supply cylinder 11, or in a straight line or in an alternating manner. The arrangement of the diversion cylinder shell 13 needs to be designed and arranged along the water supply cylinder 11 according to actual needs. The solenoid valve core 2 can be matched and inserted in the socket cavity 103, and each solenoid valve core 2 is equipped with a separate solenoid valve control device 3, which can easily change the water outlet state of multiple drainage pipe outlets 112, and the solenoid valve core 2 and the matching solenoid valve control device 3 can be easily disassembled for cleaning and maintenance.

[0027] In another technical solution, any three diverter shells 13 arranged axially along the water supply cylinder 11 are arranged in a U-shaped arrangement on both horizontal sides of the water supply cylinder 11. The shells of all diverter shells 13 are integral and the internal socket cavities 103 are separated from each other. The three diverter shells 13 arranged in a U-shaped arrangement can be compressed axially by more than one third to reduce the overall volume.

[0028] In another technical solution, a valve core water outlet 24 is provided at the bottom of the solenoid valve core 2, and the valve core water outlet 24 is cylindrical, with one end of the valve core water outlet 24 inside the solenoid valve core 2 and the other end matching and docking with the port of the upper curved pipe section 113. A pressure relief pipe 21 is provided downwardly on the inner top wall of the solenoid valve core 2, and the lower end of the pressure relief pipe 21 extends into the drainage cavity 103. A first pressure relief hole 201 is connected to the outside of the top of the solenoid valve core 2 in the pressure relief pipe 21, and a second pressure relief hole 202 is connected to the top of the solenoid valve core 2 on the outside of the pressure relief pipe 21. The opening and closing component 22 includes a deformable rubber diaphragm 221 horizontally embedded in the inner wall of the solenoid valve core 2, and the middle part of the rubber diaphragm 221 is tightly sleeved on the outside of the pressure relief pipe 21, and the rubber diaphragm 221 blocks the pressure relief pipe 21. The gap between the top of the valve core water outlet 24 and the outer wall of the pressure relief pipe 21, the rubber transverse membrane 221 divides the electromagnetic valve core 2 into a first cavity 1031 and a second cavity 1032, the second cavity 1032 is connected to the water supply cavity 101 space, and the rubber transverse membrane 221 is provided with a diaphragm pressure relief hole 220; the electromagnetic control device 3 is matched and installed on the upper part of the electromagnetic valve core 2, and the bottom of the electromagnetic control device 3 is provided with a third cavity 301, the third cavity 301 is connected to the first cavity 1031 through the second pressure relief hole 202, and the third cavity 301 is connected to the pressure relief pipe 21 through the first pressure relief hole 201, and there is a vertically movable sliding column 31 in the electromagnetic control device, and the bottom end of the sliding column 31 blocks the first pressure relief hole 201.

[0029] In the present technical solution, the electromagnetic valve core 2 can be matched and inserted into the socket of the diversion shell 13. When one drainage pipe port 112 is closed, the rubber diaphragm 221 is sealed at the top of the valve core water outlet 24. At this time, the slide column 31 is not affected by the electromagnetic force to block the first pressure relief hole 201. The first cavity 1031, the second cavity 1032, and the third cavity 301 are filled with water and the water pressure is consistent. When the water outlet operation is required, the slide column 31 is raised by the electromagnetic force, and the water stored in the third cavity 301 immediately flows from the first pressure relief hole 201 along the pressure relief pipe 21 into the drainage cavity 102. The water pressure in the third cavity 301 changes, so that the water stored in the first cavity 1031 flows into the third cavity 301 along the second pressure relief hole 202. At this time, the water volume in the first cavity 1031 decreases and a pressure difference is formed between the second cavity 1032. Since the rubber diaphragm 221 is a retractable structure, the edge of the rubber diaphragm 221 is affected by the water pressure. The second cavity 1032 is connected with the drainage cavity 102 at this time, and the water inside the second cavity 1032 and the connected water supply cavity 101 can be discharged smoothly. When the water flow needs to be closed, the electromagnetic force on the sliding column 31 disappears, the sliding column 31 returns to its original position and blocks the first pressure relief hole 201, and the water pressure in the third cavity 301 increases and flows back from the second pressure relief hole 202 to the first cavity 1031. The water pressure in the first cavity 1031 increases instantaneously, so that the rubber diaphragm 221 returns to its shape before deformation and covers the top of the valve core water outlet 24. Before the rubber diaphragm 221 is deformed, the diaphragm pressure relief hole 220 connects the first cavity 1031 and the second cavity 1032, so that the water pressure in the two cavities is consistent under static water state. When the rubber diaphragm 221 is deformed, the diaphragm pressure relief hole 220 is squeezed and closed, so that there is water pressure above and below the rubber diaphragm 221 and the deformation state is maintained.

[0030] In another technical solution, the electromagnetic control device 3 includes a housing 30, an electromagnetic coil 32, and a sleeve 310 assembled at the center of the electromagnetic coil 32. The sliding column 31 is matched and sleeved in the sleeve 310. A first spring 311 is fixed in the sleeve 310, one end of which is fixed to the inner wall of the housing 30 and the other side is fixed to the end of the sliding column 31. The electromagnetic coil 32 is separated from the third cavity 301, and the sleeve 310 is connected to the third cavity 301. The electromagnetic coil 32 can control the sliding column 31 to compress the first spring 311 to complete the upper The electromagnetic control device 3 is moved to release the blockage of the first pressure relief hole 201. The third cavity 301 is separated from the electromagnetic coil 32 to prevent water from entering the inside. A control circuit board 33 is also fixed in the shell of the electromagnetic control device 3. The control circuit board 33 can receive an external signal. When a signal to turn on the faucet is received, the electromagnetic coil 32 is energized, and the slide column 31 is magnetically attracted and moved upward to connect the third cavity 301 with the first pressure relief hole 201. When a signal to close the faucet is received, the electromagnetic coil 32 is de-energized, and the slide column 31 is reset and blocks the first pressure relief hole 201.

[0031] In another technical solution, a second spring 23 is connected between the upper surface of the rubber diaphragm 221 and the top wall inside the electromagnetic valve core 2. When the rubber diaphragm 221 is deformed, the second spring 23 compresses but keeps the rubber diaphragm 221 from being deformed too much.

[0032] In another technical solution, the connection between the rubber diaphragm 221 and the inner side wall of the electric measuring valve core 2 is a pleated structure 222, and the cross section of the pleated structure 222 is bow-shaped. The pleated structure 222 makes the rubber diaphragm 221 more easily deformed.

[0033] In another technical solution, a sealing ring 4 is provided at the intersection of the valve core water outlet 24 and the upper bend pipe section 13 port, a sealing ring 4 is provided at the intersection of the solenoid valve core 2 and the socket 13, and a sealing ring 4 is provided at the intersection of the third cavity 301 and the solenoid valve core 2, and the sealing ring 4 is made of a deformable and recoverable material.

[0034] In another technical solution, the top outer wall of the solenoid valve core 2 has a stepped structure protruding at the position of the first pressure relief hole 201, and the bottom of the sliding column 31 touches the surface of the stepped structure and blocks the first pressure relief hole 201. The stepped structure of the first pressure relief hole 201 makes it more difficult for water in the third cavity 301 to leak out of the first pressure relief hole 201.

[0035] The number of components and processing scale described here are used to simplify the description of the utility model. Applications, modifications and variations of the utility model are obvious to those skilled in the art.

[0036] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented.
