[0007] By adopting the above technical solution, water passes through the valve mouth and the power magnet in sequence, and then enters the connecting groove from the water inlet hole of the valve core. After the electromagnetic coil is energized, it is separated by electromagnetic induction, so that the power magnet drives the valve core to rotate synchronously through the linkage mechanism. When the power magnet rotates forward, the connecting groove is connected to the first water outlet, and when the power magnet rotates reversely, the connecting groove is connected to the second water outlet, so that water is discharged from the first water outlet or the second water outlet. Compared with the existing motor as a power source, its structure is simpler, the response is faster, and the service life is longer.

[0011] By adopting the above technical solution, during installation, the power magnet is placed in the valve sleeve. Since the plurality of protrusions are arranged non-uniformly, the power magnet plays a directional role, so as to facilitate the connection between the power magnet and the valve core.

[0012] The utility model is further configured as follows: a limiting structure for limiting the rotation angle of the valve core is arranged between the valve body and the valve core.

[0020] The utility model is further configured as follows: a water pressure balancing mechanism is provided between the valve sleeve, the valve nozzle and the valve core.

[0021] By adopting the above technical solution and setting the water pressure balancing mechanism, the valve core is not easily stuck on the valve body due to excessive water pressure, so that the valve core can rotate stably and smoothly.

[0022] The utility model is further configured as follows: the water pressure balancing mechanism includes a circular hole and a contact plate, a plurality of the circular holes are opened on the valve mouth and are connected with the water inlet, the contact plate is fixed to the side of the valve core facing the valve body and is used to contact with the surface of the valve body, a water flow channel is provided between the valve sleeve and the power magnet and the outer wall of the valve core, and the water flow channel is connected with the connecting groove.

Another part of the water passes through the valve mouth and the water inlet hole and then enters the connecting groove, so that the water pressure on both sides of the valve core can be kept stable, avoiding the valve core and the valve body from getting stuck.

DETAILED DESCRIPTION

[0039] The utility model is further described with reference to the accompanying drawings.

[0040] like Figures 1 to 12 As shown, a loom water diverter valve comprises a valve sleeve 1, in which a valve mouth 2, a power magnet 3, a valve core 4 and a valve body 6 are sequentially arranged along the water flow direction. The valve mouth 2 is threadedly fixedly connected to one end of the valve sleeve 1. One end of the valve mouth 2 has a screw sleeve 21, which is located outside the valve sleeve 1, and the other end of the valve mouth 2 is a connecting portion 22 in the shape of a circular tube, which is placed inside the valve sleeve 1. A water inlet is provided on the valve mouth 2, and the water inlet is coaxially arranged with the valve mouth 2.

[0041] The connection part 22 of the valve mouth 2 is sleeved with a power magnet 3, which can be rotatably connected to the connection part 22 and is located inside the valve sleeve 1. There is a gap between the end of the power magnet 3 and the end of the screw sleeve 21. The power magnet 3 and the valve sleeve 1 are clearance-fitted.

[0042] The valve core 4 is rotatably connected in the valve sleeve 1, and the power magnet 3 drives the valve core 4 to rotate through the linkage mechanism. A water inlet hole is provided in the middle of the valve core 4, and the water inlet hole is coaxially arranged with the valve core 4. The valve core 4 and the valve sleeve 1 are also clearance-fitted. The linkage mechanism includes a clamping ring 51, a clamping groove 52, a convex ring 53, and a convex block 54. Among them, the clamping ring 51 is fixed to the side of the valve core 4 facing the power magnet 3, and the clamping ring 51 is coaxially arranged with the valve core 4. Four clamping grooves 52 are provided on the surface of the clamping ring 51.

[0043] The convex ring 53 is fixed to the side of the power magnet 3 facing the valve core 4. Four protrusions 54 are fixed to the convex ring 53, and the four protrusions 54 are respectively arranged along the radial direction of the convex ring 53 at 0°, 120°, 180°, and 240°. In each clamping groove 52, a protrusion 54 is embedded. When the power magnet 3 rotates, the protrusion 54 contacts the inner wall of the clamping groove 52 and enables the valve core 4 to rotate synchronously with the power magnet 3. That is, the arrangement of the clamping groove 52 on the clamping ring 51 is the same as the arrangement of the protrusion 54 on the convex ring 53.

[0044] A connecting groove 41 is provided on the side of the valve core 4 facing away from the power magnet 3. The connecting groove 41 is fan-shaped and symmetrically arranged along the radial direction of the valve core 4. The connecting groove 41 is connected to the water inlet.

[0045] Two partitions 42 are fixedly connected to the connection groove 41, with a first gap 43 between the two partitions 42, a second gap 44 between the partition 42 and the inner wall of the connection groove 41, and the partition 42 is close to the water inlet. The two partitions 42 are symmetrically arranged along the radial direction of the valve core 4, and the cross section of the partition 42 is fan-shaped and is coaxially arranged with the water inlet. The angle a of the first gap 43 is 32°; the angle b between the two end faces of the partition 42 is 39.86°; and the angle c of the second gap 44 is 28.62°.

[0046] The valve body 6 is fixed to the valve sleeve 1 in a threaded manner, and a first water outlet 61 and a second water outlet 62 are provided on the valve body 6, and the first water outlet 61 and the second water outlet 62 are evenly distributed along the axis of the valve body 6. A limiting structure for limiting the rotation angle of the valve core 4 is provided between the valve body 6 and the valve core 4. The limiting structure includes a limiting column 71 and an arc groove 72. Among them, the limiting column 71 is fixed to the side of the valve body 6 facing the valve core 4, and the limiting column 71 and the valve body 6 and the valve core 4 cannot be coaxially arranged. The arc groove 72 is provided on the side of the valve core 4 facing the valve body 6, and the limiting column 71 is placed in the arc groove 72. When the limiting column 71 conflicts with the end of the arc groove 72, the connecting groove 41 is connected to the first water outlet 61 or the second water outlet 62.

[0047] There is a water pressure balancing mechanism between the valve sleeve 1, the valve mouth 2 and the valve core 4. The water pressure balancing mechanism includes a circular hole 81 and a contact plate 82. A plurality of circular holes are opened on the connecting portion 22 of the valve mouth 2 and are connected to the water inlet, and the plurality of circular holes are evenly distributed along the axis of the connecting portion 22. The circular holes are located in the interval. The contact plate 82 is fixed to the side of the valve core 4 facing the valve body 6 and is used to contact the surface of the valve body 6. There are three contact plates 82 in total, of which two contact plates 82 have circular cross-sections and are respectively located at the two ends of the connecting groove 41. The cross-section of one contact plate 82 is strip-shaped and is located in the middle of the connecting groove 41, so that the edge of the connecting groove 41 cannot form a closed structure with the valve body 6. The thickness of the three contact plates 82 is 0.2 mm.

[0048] Since there is clearance fit between the valve sleeve 1 and the power magnet 3 as well as between the valve sleeve 1 and the valve core 4 , a water flow channel is formed, and the water flow channel is communicated with the connecting groove 41 .

[0049] An electromagnetic coil 91 for driving the power magnet 3 to rotate is fixedly connected to the outer wall of the valve sleeve 1. The electromagnetic coil 91 has two sets of power coils, and the winding directions of the two sets of power coils are opposite. When one power coil is energized, the power magnet 3 can rotate forward by electromagnetic induction; similarly, when the other power coil is energized, the power magnet 3 rotates in the opposite direction.

[0050] Most of the water passes through the water inlet, the power magnet 3, the water inlet hole, the first gap 43, and the second gap 44 into the connection groove 41. When the power magnet 3 rotates forward, the valve core 4 rotates forward along with the power magnet 3, and the limit column 71 contacts the inner wall of the arc groove 72. At this time, the connection groove 41 is connected with the first water outlet 61, and at the same time, the connection groove 41 is misaligned with the second water outlet 62. At this time, water can only be discharged from the first water outlet 61. Similarly, when the power magnet 3 rotates in the opposite direction, the connection groove 41 is connected with the second water outlet 62, and at the same time, the connection groove 41 is misaligned with the first water outlet 61, and water can only be discharged from the second water outlet 62.

[0051] A small amount of water enters the water flow channel from the circular hole, and then enters the connecting groove 41 along the gap between the resistance plate 82 and the valve body 6, so as to achieve stable water pressure on both sides of the valve core 4, avoiding the problem that the valve core 4 cannot rotate due to the jamming between the valve core 4 and the valve body 6.

[0052] In order to provide good support for the valve body 6, a valve seat 92 is provided outside the valve sleeve 1. The end of the valve body 6 is fixed on the valve seat 92. A support foot 93 is fixedly connected to the valve seat 92, and one end of the support foot 93 away from the valve seat 92 is fixedly connected to the outer wall of the electromagnetic coil 91.

[0053] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
