The water diverter valve can be operated to select water to flow out from the faucet, shower head, shower head or other water outlet components, thereby forming a variety of water outlet modes.

[0003] A known induction faucet has a valve core arranged inside, the valve core includes a valve core outer cover and a valve core body, the valve core body is located inside the valve core outer cover, the valve core body includes an upper ceramic water sealing cover, a lower ceramic water sealing cover and a valve core connecting rod, the lower part of the valve core connecting rod is provided with a protruding column, the protruding column is inserted into the groove of the upper ceramic water sealing cover, the lower end of the valve core connecting rod is provided with a magnet mounting groove near the edge of the valve core outer cover, a magnet is installed in the magnet mounting groove, the valve core has two Hall sensing elements, each Hall sensing element is respectively arranged on the outside of the valve core outer cover and close to the valve core outer cover, when the valve core connecting rod is rotated clockwise, the valve core connecting rod drives the magnet to rotate, the magnet approaches one Hall sensing element, thereby generating a signal to control the on and off of water, when the valve core connecting rod is rotated counterclockwise, the valve core connecting rod drives the magnet to rotate, the magnet approaches another Hall sensing element, thereby generating another signal to control the on and off of water.

[0004] The valve core connecting rod is manually operated to rotate. When the rotation angle of the valve core connecting rod fails to reach the set angle, the valve core connecting rod is used to drive the magnet to rotate, so that the magnet is close to different Hall sensing elements respectively, and a signal is generated to control the water flow, thereby avoiding human operating errors and causing the faucet to fail to completely close.

[0019] Figures 1 to 7The present invention is an embodiment of the valve core of the water diverter valve with embedded magnetic body, but such embodiments are for illustration only and the patent application is not limited to such structure.

[0020] like Figures 1 to 4 As shown, the first embodiment of the valve core of the water diverter valve with embedded magnetic body comprises a valve housing 10, a valve stem 20, a driving member 30, a movable valve disc 40, a fixed valve disc 50 and a valve seat 60, wherein the valve housing 10 forms a shell-shaped body with a space 12 inside, the driving member 30, the movable valve disc 40 and the fixed valve disc 50 are arranged in the space 12, the movable valve disc 40 and the fixed valve disc 50 are respectively made of ceramic materials, the movable valve disc 40 and the fixed valve disc 50 are overlapped and can rotate relatively, the driving member 30 and the movable valve disc 40 are The valve seat 60 is connected and moved in conjunction with each other. The valve seat 60 is assembled at one end of the valve housing 10, and a leak-proof element 52 is provided between the fixed valve disc 50 and the valve seat 60. The fixed valve disc 50 and the valve seat 60 form a watertight connection through the leak-proof element 52. Several flow channels 70 penetrate the valve seat 60 and the fixed valve disc 50, and the water flow path is changed by rotating the movable valve disc 40. One end of the valve stem 20 is connected to the driving member 30, and the other end of the valve stem 20 protrudes from the outside of the valve housing 10, so that the valve stem 20 drives the driving member 30 and the movable valve disc 40 to move.

[0021] The valve stem 20 is selectively constructed, and the valve stem 20 can be set or not as needed; the number of flow channels 70 and the specific structure of the flow channels 70 can be changed as needed. The number and specific structure of the flow channels 70 shown in the figure are only an example and cannot be used as a limitation to explain the present invention. Different designs of the flow channels 70 can achieve different forms of on-off changes of the flow channels 70 when the movable valve plate 40 is actuated. People skilled in the relevant technical field can change the number and specific structure of the flow channels 70 as needed according to the purpose of use.

[0022] A magnetic body 80 is provided between the driving member 30 and the movable valve plate 40. The magnetic body 80 is an elongated rod-shaped body. In this example, the magnetic body 80 is selected to be composed of a permanent magnet. The magnetic body 80, the driving member 30 and the movable valve plate 40 form a linkage relationship. One end of the magnetic body 80 along the elongated direction is a first magnetic pole 81, and the other end of the magnetic body 80 along the elongated direction is a second magnetic pole 82. The polarities of the first magnetic pole 81 and the second magnetic pole 82 are different. The first magnetic pole 81 and the second magnetic pole 82 are respectively close to the two sides of the valve housing 10 facing the space 12.

[0023] A first axis L1 is defined to pass through the driving member 30 and the movable valve plate 40, and a second axis L2 is defined to pass through the first magnetic pole 81 and the second magnetic pole 82, and the first axis L1 and the second axis L2 are orthogonal to each other, so that the driving member 30 drives the magnetic body 80 to move or the magnetic body 80 drives the movable valve plate 40 to move.

[0024] Furthermore, the first axis L1 passes through the centers of the driving member 30 , the movable valve plate 40 and the magnetic body 80 , and the first axis L1 and the first magnetic pole 81 and the second magnetic pole 82 are equidistant, which is a preferred implementation option.

[0025] Please cooperate Figure 5 As shown, when the first embodiment is applied to the water diversion valve, a plurality of coils 92 can be configured in an annular shape on the outside of the valve housing 10. Each coil 92 can provide current to pass through to generate a magnetic field. Each coil 92 is close to the valve housing 10, and each coil 92 is located in the space where the second axis L2 is located, so that each coil 92 forms a relative state with the magnetic body 80 in a direction perpendicular to the first axis L1. When current passes through each coil 92, each coil 92 generates a magnetic field. By controlling the direction of the current passing through each coil 92, the direction of the magnetic field of each coil 92 can be changed. The first magnetic pole 81 and the second magnetic pole 82 respectively form magnetic attraction or magnetic repulsion with the magnetic fields generated by different coils 92, and the magnetic body 80 then rotates around the first axis L1, thereby causing the magnetic body 80 to drive the driving member 30 and the movable valve plate 40 to rotate. A control unit (not shown in the figure) composed of an electronic circuit controls the current to select a specific coil 92 and controls the current direction and current intensity passing through the coil 92, thereby automatically controlling the rotation angle of the movable valve plate 40 driven by the magnetic body 80 and the torque of the movable valve plate 40 driven by the magnetic body 80.

[0026] The first axis L1 passes through the center of the driving member 30 and the movable valve plate 40, the second axis L2 passes through the first magnetic pole 81 and the second magnetic pole 82, and the first axis L1 and the second axis L2 form an orthogonal related structure. In combination with the first magnetic pole 81 and the second magnetic pole 82 respectively approaching the two sides of the valve shell 10 facing the space 12, when the magnetic body 80 is rotated by the magnetic field of each coil 92, the magnetic body 80 can provide a torque sufficient to drive the driving member 30 and the movable valve plate 40 to move, and can effectively and reliably control the rotation angle of the movable valve plate 40 driven by the magnetic body 80, so as to automatically control the water diversion valve to switch to different water outlet modes. The conversion between the water outlet modes is rapid and reliable, and the driving member 30 and the movable valve plate 40 are subjected to balanced force, and no biased force phenomenon occurs, thereby reducing the wear between the movable valve plate 40 and the fixed valve plate 50, which is conducive to improving the service life.

[0027] like Figure 6As shown, in the case where the valve stem 20 is provided in the first embodiment, when it is applied to the water diversion valve, a plurality of Hall sensing elements 94 can be configured on the outside of the valve housing 10, each Hall sensing element 94 is close to the valve housing 10, and each Hall sensing element 94 is located in the space area where the second axis L2 is located. The valve stem 20 is manually operated to rotate the driving member 30 and the movable valve plate 40. When switching different water outlet modes, the magnetic body 80 rotates around the first axis L1, and the first magnetic pole 81 or the second magnetic pole 82 is opposite to a specific Hall sensing element 94. The Hall sensing element 94 generates a signal, which can trigger an electronic component (not shown in the figure) or an electronic device (not shown in the figure) to work. The electronic component can be an LED or a sound generator. By using the flickering change of the LED or the sound generator to send a specific sound message, the first embodiment can be used as a water diversion valve that can trigger sound and light effects, and can improve the guidance or fun of the water diversion valve in use. It can also be used as a guide for hearing-impaired or visually impaired people, and has extremely high industrial value.

[0028] By setting the magnetic body 80, the movable valve plate 40 can be driven by the magnetic body 80, or the driving member 30 can be driven by the magnetic body 80 and the movable valve plate 40, thereby implementing two different control modes: automatic control or manual control.

[0029] like Figures 2 to 4 As shown, a first embedding groove 32 is formed at one end of the driving member 30 facing the movable valve plate 40, and the magnetic body 80 is embedded in the first embedding groove 32, so that the magnetic body 80 forms a linkage relationship with the driving member 30 and the movable valve plate 40. The magnetic body 80 is embedded in the first embedding groove 32, and the first embedding groove 32 is provided with two first limiting portions 34. The magnetic body 80 is arranged between each first limiting portion 34, and the first magnetic pole 81 and the second magnetic pole 82 are respectively adjacent to each first limiting portion 34. Each first limiting portion 34 forms a stop for the magnetic body 80, thereby positioning the magnetic body 80.

[0030] A second embedding groove 42 is formed at one end of the movable valve plate 40 facing the driving member 30, and the magnetic body 80 is embedded in the second embedding groove 42, so that the magnetic body 80 forms a linkage relationship with the driving member 30 and the movable valve plate 40. The magnetic body 80 is embedded in the second embedding groove 42, and the second embedding groove 42 is provided with two second limiting portions 44. The magnetic body 80 is arranged between each second limiting portion 44, and the first magnetic pole 81 and the second magnetic pole 82 are respectively adjacent to each second limiting portion 44. Each second limiting portion 44 forms a stop for the magnetic body 80, thereby positioning the magnetic body 80.

[0031] Since the driving member 30 is connected to the movable valve plate 40, it is possible to select only the first embedding groove 32 or the second embedding groove 42 as needed, thereby forming a variation implementation selection not shown in the figure. At this time, the magnetic body 80 is selectively embedded in the first embedding groove 32 or the second embedding groove 42, so that the magnetic body 80, the driving member 30 and the movable valve plate 40 form a linkage relationship.

[0032] Two protrusions 36 are convexly provided on one end of the driving member 30 facing the movable valve plate 40, and the magnetic body 80 is arranged between the protrusions 36, and the protrusions 36 are symmetrical with respect to the second axis L2 as the center. The movable valve plate 40 is recessed into two recesses 46 to cooperate with the protrusions 36, and the protrusions 36 are respectively embedded in the recesses 46, so that the driving member 30 and the movable valve plate 40 are connected and moved in conjunction. Through the relative structure of the protrusions 36, the recesses 46 and the magnetic body 80 in space, when the magnetic body 80 drives the driving member 30 and the movable valve plate 40 to rotate, the driving member 30 and the movable valve plate 40 are subjected to balanced force.

[0033] like Figure 7 As shown, the main difference between the second embodiment and the first embodiment is that the magnetic body 80 is mainly composed of a first magnetic block 83, an intermediate block 84 and a second magnetic block 85. The first magnetic block 83, the intermediate block 84 and the second magnetic block 85 are arranged along the second axis L2, and the intermediate block 84 is arranged between the first magnetic block 83 and the second magnetic block 85. The first magnetic block 83 and the second magnetic block 85 are permanent magnets respectively, and the intermediate block 84 is made of a material with high magnetic permeability. The first magnetic block 83 forms a first magnetic pole 81 at one end facing the valve housing 10, and the second magnetic block 85 forms a second magnetic pole 82 at one end facing the valve housing 10.

[0034] In the second embodiment, the size of the magnetic body 80 can be changed as needed. When the size of the magnetic body 80 is larger, the intermediate block 84 is used so that the magnetic body 80 can still have sufficient magnetic force for operation, thereby reducing the volume and weight ratio of the permanent magnets required to constitute the magnetic body 80 and reducing the cost of the magnetic body 80.

[0035] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
