Please refer to FIG. 1 to FIG. 7 , the magnetic control multi-way valve includes a fixed unit, two control valves 100 and a second magnet 200 .

The fixing unit includes a body 300 and an upper cover 400 . The body 300 and the upper cover 400 are hermetically fixed together, and the fixed unit has a water inlet 310 capable of connecting to an external water source and two mutually independent mounting cavities 320 horizontally arranged at intervals. The mounting cavities 320 The lower port forms a water outlet 330, and the fitting cavity 320 and the water outlet 330 are preferably coaxial. In this embodiment, an upward stepped surface is provided inside the installation cavity 320 , and a convex ring 340 protrudes from the stepped surface. In this embodiment, the two installation chambers 320 are respectively defined as an installation chamber 320A and an installation chamber 320B, and the two water outlets 330 are respectively defined as a water outlet 330A and a water outlet 330B.

The two control valves 100 are installed in the two installation chambers 320 respectively. The control valve 100 includes a spool assembly 110 , a first magnet 120 , a gasket 130 , a first spring 140 and a second spring 150 . The valve core assembly 110 is fixed in the mounting cavity 320, the first magnet 120 can slide up and down in the mounting cavity 320 and is located on the valve core assembly 110, and the sealing gasket 130 can slide up and down in the connection Inside the installation cavity 320 and under the valve core assembly 110, the first spring 140 is arranged between the gasket 130 and the valve core assembly 110; the second spring 150 is arranged between the first magnet 120 and the valve core assembly 110 between. The gasket 130 is located on the stepped surface of the installation chamber 320 , corresponding to the protruding ring 340 of the installation chamber 320 . A first cavity 160 is formed between the valve core assembly 110 and the gasket 130 , and a second cavity 170 is formed between the valve core assembly 110 and the upper cover 400 .

The spool assembly 110 is provided with a pressure relief channel 111 that runs through the top and bottom and a second water hole 112 that runs through the top and bottom. The second water hole 112 connects the first chamber 160 and the second chamber 170, so The pressure relief channel 111 is connected to the second chamber 170 and the water outlet 330 . Preferably, a water screw 180 is provided to be screwed into the lower port of the pressure relief channel 111 of the spool assembly 110, and then the water screw 180 can connect the pressure relief channel 111 to the water outlet 330, and it can be sealed. The pad 130 plays a guiding role (the central hole 132 of the sealing pad 130 is sealed and slidably sleeved outside the water screw 180 ). A first water hole 131 is defined above the sealing pad 130 , and the first water hole 131 is used to connect the water inlet 310 and the first cavity 160 .

In order to ensure the sealing performance, preferably, a plug 121 suitable for the pressure relief channel is fixed under the first magnet 120 .

In order to ensure the accurate positioning of the first spring 140, in order to facilitate assembly, it is preferable that a fixing groove adapted to the first spring 140 is arranged on the gasket 130, and the first spring 140 is adapted to be connected to the fixing groove. Moreover, the first spring 140 has an insertion end 141 on it, and the insertion end 141 is inserted into the first water hole 131 . In order to ensure accurate positioning of the second spring 150 and to facilitate assembly, it is preferable that the upper end surface of the valve core assembly 110 is recessed with a positioning groove, and the second spring 150 is adapted to be connected to the positioning groove.

For ease of understanding, the above-mentioned two control valves 100 are respectively defined as a control valve 100A and a control valve 100B, and the corresponding components of the two control valves 100 are also defined separately, for example, the two spool assemblies 110 are respectively defined as a spool assembly 110A and a spool assembly 110A. In the assembly 110B, the two first cavities 160 are respectively defined as a first cavity 160A and a first cavity 160B and so on. In order for the examiner to clearly understand the following action principles, in Figure 1, Figure 2, Figure 5, Figure 6 and Figure 7, A and B are respectively used to distinguish the two control valves and their corresponding structures, and their structures are essentially the same , so when introducing a single control valve in Figure 3 and Figure 4, there is no distinction between A and B.

The second magnet 200 can be horizontally slidably connected to the upper cover 400 , in order to ensure smooth horizontal sliding of the second magnet 200 , it is better to cooperate with a push button 210 , two third springs 220 and two positioning beads 230 . The second magnet is fixed under the push button 210, the left and right sides of the upper cover 400 are respectively provided with slide grooves, the left and right sides of the push button 210 respectively extend downwards to form sliders, and the two slides The blocks are respectively slidably connected in the chute to realize the connection relationship to guide. The positioning ball and the third spring cooperate to convert sliding friction into rolling friction, so as to reduce the coefficient of friction. In order to prevent the push button from sliding out of the upper cover, it is better to provide a limit mechanism 240 .

In this embodiment, the shape of the second magnet 200 is the same as that of the first magnet 120 , and the magnetic poles corresponding to the lower end surface of the second magnet are opposite to those corresponding to the upper end surface of the first magnet.

As shown in FIG. 5 , the push button 210 is right above the water outlet 330B at this time, and after the water flow fills the water inlet chamber through the water inlet 310, it enters the first chamber 160A, 160B through the left and right first water holes 131A, 131B, and After filling the space, enter the second cavity 170A, 170B along the second water hole 112A, 112B;

Because there is a magnetic pole facing each other above the first magnet 120B (that is, the second magnet 200 with N pole to N pole) and repulsion occurs, the first magnet 120B drives the plug 121B to move downward to block the pressure relief port of the pressure relief channel 111B, so that The water pressure in the first chamber 160B and the second chamber 170B is the same as the water pressure in the water inlet chamber because the pressure relief port cannot discharge water; the sealing gasket 130B will reach the water outlet in the initial state due to the action of the first spring 140B The lower part of 330B is connected to the water outlet 330B, and the pressure of the water outlet 330B is the same as the atmosphere, so that the sealing gasket 130B has a downward pressure difference, blocking the water outlet 330B, so that the water outlet 330B is watertight;

Since there is no second magnet above the first magnet 120A, without repulsive force, it moves upwards under the action of the second spring 150B, and the pressure relief channel 111A is connected, so that the pressure of the first chamber 160A and the second chamber 170A are in line with the water outlet. The pressure of 330A (that is, the pressure of the atmosphere) is the same, so that the pressure at the upper end of the sealing gasket 130A is lower than the pressure at the lower end, so that the sealing gasket 130A moves upward to open to the water outlet 330A, so that the water outlet 330A starts to discharge water. Wherein: the force of the sealing gasket 130A is: F1'-F2=(P1 (the active force of the water pressure acting on the sealing gasket 130A-P2 (the active force of the atmospheric pressure acting on the sealing gasket 130A))*S-F2 (the force of the first spring Elasticity)>0.

As shown in Figure 6, push the push button to the left to the middle position, then the second magnet 200 leaves the first magnet 120B and does not reach the first magnet 120A, at this time the pressure relief ports of the pressure relief channels 111A and 111B are both opened, the same reason It can be obtained that at this time the water outlets 330A and 330B both discharge water outwards.

As shown in FIG. 7 , continue to push the push button to the left to the far left. At this time, the first magnet 120A is subjected to repulsive force, but the first magnet 120B is not affected. Similarly, the water outlet 330B is discharged, and the water outlet 330A is not discharged.

Push the knob, the above process can be cycled.

In this embodiment, a two-way valve is taken as an example, but it is not limited thereto. Others such as three-way valves are also applicable. For example, three control valves are provided, and the first magnets of the three control valves slide up and down through the second magnet to realize the on-off of the water outlet.

The above is only a preferred embodiment of the present invention, so the scope of the present invention cannot be limited accordingly, that is, the equivalent changes and modifications made according to the patent scope of the present invention and the content of the specification should still be covered by the present invention within range.
