[0004] On the basis of the above design, the applicant further improves the control assembly of the valve, and a set of control assemblies can realize three-gear adjustment (single open pipe one, single open pipe two and double open) of one-in and two-out pipelines. CONTENT OF THE UTILITY MODEL
[0005] The utility model aims at overcoming the shortcomings and deficiencies in the prior art, and provides a valve control assembly and valve, and the technical scheme adopted by the utility model is as follows:
[0006] In the first aspect, a valve control assembly is provided, which comprises a first valve core and a second valve core for controlling the on-off of fluid, a rotating disc is arranged between the first valve core and the second valve core, a first magnetic steel, a second magnetic steel and a third magnetic steel are installed on the rotating disc;
[0007] The rotating disc has a first control position in which only the second magnetic steel or the third magnetic steel corresponds to the first valve core, and the remaining two magnetic steels do not attract any valve core;
[0008] And, the rotating disc has a second control position in which only the third magnet corresponds to and attracts the second spool, and the first magnet and the second magnet do not correspond to any spool.
[0009] And, the rotating disc has a third control position in which the first magnet and the second magnet correspond to the first spool and the second spool respectively, and the first magnet and the second magnet simultaneously attract the first spool and the second spool to displace the first spool and the second spool.
[0010] Preferably, in the first control position, the rotating disc only makes the second magnet correspond to the first spool, and the first magnet and the third magnet do not attract any spool, so that the first control position can be directly switched to when operating, without affecting other spools.
[0011] In the present application, the "correspondence" between the magnet and the spool means that the rotating disc is rotated to a position where the magnet is located in front of the target spool and is closest to the target spool in the movement track of the magnet.
[0012] Preferably, the rotating disc further has a fourth control position in which the first magnet, the second magnet and the third magnet do not correspond to any spool. When the rotating disc is in the fourth control position, the valve control assembly does not drive any spool.
[0013] Preferably, the first magnet, the second magnet and the third magnet are distributed at intervals around the rotating disc.
[0014] Preferably, the first magnet, the second magnet and the third magnet are embedded in the embedding slots on the rotating disc.
[0015] Preferably, the first magnet, the second magnet and the third magnet are (approximately) distributed on the same straight line on the rotating disc, and there is an included angle between the second magnet and the third magnet.
[0016] Preferably, the power source is a stepper motor.
[0017] As preferred, the effective distance of the magnetic steel interacting with the valve core and capable of attracting the valve core to displace is L, when the first magnetic steel corresponds to the second valve core, the distance between the two is greater than L; this design is to avoid the opening of the valve caused by the magnetic steel passing by the non-target valve core during the rotation of the rotating disc; those skilled in the art can understand that the setting of an obstacle or a material with certain shielding property between the magnetic steel and the valve core can reduce L, thus the method of making the distance between the first magnetic steel and the second valve core greater than L can be simply making the two away from each other (increasing the distance in space), or setting a shielding material between the two (reducing L), or a combination of the two methods; one implementation method can be: thickening the shell wall thickness of the second valve core, moving the first magnetic steel away from the outer periphery of the rotating disc, increasing the distance between the two, so that the first magnetic steel does not attract the second valve core to move when passing by the second valve core during rotation, avoiding the opening of the second valve core; in this way, only when the first magnetic steel corresponds to the first valve core and the second magnetic steel corresponds to the second valve core, can the two valve cores be simultaneously driven to displace, that is, the rotating disc has a unique third control position; at the same time, the shell wall thickness outside the first valve core is normal, and the first magnetic steel can normally attract the first valve core to displace when corresponding to the first valve core.
[0018] In a second aspect, a valve, which can be a toilet flushing electromagnetic valve, is provided, which includes a water inlet pipe and a first water outlet pipe and a second water outlet pipe in communication with the water inlet pipe, and a valve control assembly as described above is arranged between the first water outlet pipe and the second water outlet pipe.
[0019] Specifically, a first pressure relief valve and a second pressure relief valve are arranged on the first water outlet pipe and the second water outlet pipe respectively, a first valve core and a first valve core return member are arranged in the first pressure relief valve, and a second valve core and a second valve core return member are arranged in the second pressure relief valve; when the magnetic steel corresponding to the valve core is driven by the rotating disc to rotate, the magnetic steel attracts the valve core to open the valve; the valve core return member can be a spring.
[0020] The beneficial effects of the utility model are as follows: in the technical scheme, the valve control assembly controls the opening and closing of two valve cores on both sides of the rotating disc through three magnetic steels on the rotating disc; the rotating disc drives the three magnetic steels to rotate, and the relative positions of the three magnetic steels relative to the two valve cores are changed, so that the three magnetic steels have a first control position and a second control position corresponding to and attracting the first valve core or the second valve core respectively, and a third control position attracting the two valve cores simultaneously; the device has the advantages of simple structure, ingenious design, strong practicability and good application prospect.

The subsequent embodiments will not be described one by one.
[0032] The directional and positional terms used in this utility model, such as "up," "down," "front," "back," "left," "right," "inner," "outer," "top," "bottom," and "side," are merely for reference to the accompanying drawings. Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.
[0033] Example 1
[0034] like Figures 1-4 As shown, a valve includes an inlet pipe 1 and a first outlet pipe 21 and a second outlet pipe 22 connected to the inlet pipe 1, and a valve control assembly 3 is provided between the first outlet pipe 21 and the second outlet pipe 22.
[0035] The valve control assembly includes a first valve core 41 and a second valve core 42 for controlling the flow of fluid. A turntable 34 is provided between the first valve core 41 and the second valve core 42. A first magnet 31, a second magnet 32, and a third magnet 33 are mounted on the turntable 34.
[0036] The turntable 34 has a first control position in which only the second magnet 32 corresponds to and attracts the first valve core 41, and neither the first magnet 31 nor the third magnet 33 attracts either valve core.
[0037] Furthermore, the turntable 34 has a second control position in which only the third magnet 33 corresponds to and attracts the second valve core 42, and the first magnet 31 and the second magnet 32 do not correspond to either valve core.
[0038] Furthermore, the turntable 34 has a third control position in which the first magnet 31 and the second magnet 32 simultaneously correspond to the first valve core 41 and the second valve core 42, respectively, thereby causing the two magnets to simultaneously attract the displacement of the two valve cores; the power source drives the turntable 34 to rotate to realize the switching of the first control position, the second control position, and the third control position.
[0039] A first pressure relief valve 401 and a second pressure relief valve 402 are respectively installed on the first water outlet pipe 21 and the second water outlet pipe 22. The first pressure relief valve 401 is provided with a first valve core 41 and a first valve core reset component. The second pressure relief valve 402 is provided with a second valve core 42 and a second valve core reset component. The turntable 34 rotates so that the magnet attracts the valve core to open the pressure relief valve, thereby realizing the connection between the water inlet pipe 1 and the first water outlet pipe 21, and / or the second water outlet pipe 22.
[0040] Furthermore, the turntable 34 also has a fourth control position in which the first magnet 31, the second magnet 32, and the third magnet 33 do not correspond to any valve core. When the turntable is in the fourth control position, this control component does not drive any valve core.
[0041] For details on the rotation of the turntable, please refer to...Figures 5-8 , Figure 5 The diagram shown illustrates the turntable in the fourth control position. Figure 5 Rotate the turntable counterclockwise to the position shown. Figure 6 As shown, the turntable is in the second control position; continue rotating the turntable counterclockwise until... Figure 7 As shown, the turntable is in the third control position; from Figure 5 Rotate the turntable clockwise to the position shown. Figure 8 As shown, the turntable is in the first control position. At this time, although the first magnet 31 is in front of the second valve core 42, it does not attract the second valve core 42.
[0042] Specifically, the first magnet 31, the second magnet 32, and the third magnet 33 are spaced apart around the turntable 34 and embedded in the grooves on the turntable 34; the first magnet 31 and the second magnet 32 are distributed on the same straight line, and there is an angle between the first magnet 31, the second magnet 32 and the third magnet 33.
[0043] In this embodiment, the power source is a stepper motor 301. Compared with the coil energizing to attract the valve core, the stepper motor drives the turntable to rotate, which is faster, more precise, easier to operate, and has a longer service life.
[0044] Furthermore, let L be the effective distance at which the magnet interacts with the valve core and can attract the valve core to move. When the first magnet 31 corresponds to the second valve core 42, the distance between them is greater than L. In this embodiment, the first magnet 31 is made to be farther from the edge of the turntable than other magnets, that is, the first magnet is closer to the center of the turntable. At the same time, the outer cover of the second valve core is thickened. Figure 4 This design weakens the interaction force between the first magnet and the second valve core, preventing the second valve core from being moved. Simultaneously, the outer casing of the first valve core maintains a normal wall thickness, allowing the first magnet to normally move the first valve core when it aligns with it. This configuration ensures that when the first magnet 31 aligns with the first valve core 41 and the second magnet 32 aligns with the second valve core 42, both valve cores can be moved simultaneously. In other words, the turntable 34 has a unique third control position, preventing the first magnet from moving the second valve core when it rotates past its vicinity.
[0045] Example 2
[0046] The difference between Embodiment 2 and Embodiment 1 is that, in the first control position, only the third magnet 33 corresponds to the first valve core 41, while the first magnet 31 and the second magnet 32 do not attract either valve core. Compared to Embodiment 1, this design requires rotation control from the third control position ( Figure 7 Continue rotating counterclockwise.
[0047] The above disclosed is only the preferred embodiment of the present application, of course, cannot be limited by this to limit the scope of the present application, therefore, the equivalent changes made according to the present application claims, still belong to the scope covered by the present application.
