[0024] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0025] like Figure 1-Figure 5 As shown, a specific embodiment of the utility model provides a linkage switching valve, including a water-dividing body 1, a button 2, a water-sealing valve body 3, a linkage disk 4 and an elastic arm 5; the water-dividing body 1 is provided with a water inlet channel 6 and a plurality of water outlet channels 7; the linkage disk 4 is rotatably arranged in the water-dividing body 1, and a track groove 41 is arranged on the side; the number of the water-sealing valve bodies 3 is the same as the number of the water outlet channels 7, and is used to control the opening and closing of the corresponding water outlet channels 7; a spherical body 31 is arranged on one side of the water-sealing valve body 3, and the spherical body 31 extends into the track groove 41; the water-sealing valve body 3 is also provided with a positioning groove 32, the button 2 is connected to the water-sealing valve body 3, and can push the water-sealing valve body 3 to move axially; the elastic arm 5 is arranged at a predetermined height of the water-dividing body 1, and abuts against the side of the water-sealing valve body 3, so that when the water-sealing valve body 3 is pressed to reach a predetermined position, the elastic arm 5 is engaged and fixed with the positioning groove 32.

[0026] With this embodiment, the lifting and lowering of the water sealing valve body 3 is controlled by the linkage disk 4. When a certain water sealing valve body 3 descends, the spherical body 31 moves vertically in the track groove 41, and pushes the linkage disk 4 to rotate during the movement, and finally reaches the lowest point of the track groove 41. The spherical body 31 of the remaining water sealing valve bodies 3 is at a higher position of the track groove 41 under the drive of the linkage disk 4, so as to return to the reset state of closing the water circuit, ensuring that only one water circuit is connected at the same time, realizing the water circuit switching function, and the button switching feels smooth, with a light damping feeling similar to that of an electronic button, and the user experience is good. The elastic arm 5 can reliably fix the water sealing valve body 3 to prevent the water sealing valve body 3 from rebounding under the action of water pressure and closing the water circuit.

[0027] Specifically, the water-dividing body 1 is composed of a central body 11, an upper sealing cover 12, a lower sealing cover 13 and a pressing cover 14. A water-dividing chamber 15 is provided in the water-dividing body 1, a partition plate 16 is provided on the top of the water-dividing chamber 15, and a plurality of connecting holes 161 are provided on the partition plate 16; the water-dividing chamber 15 is connected to the water inlet channel 6, and the connecting holes 161 correspond to the water outlet channel 7 one by one; the water-sealing valve body 3 includes a button connecting part 33 and a middle sealing ring 34, the button connecting part 33 is connected to the button 2, and the middle sealing ring 34 is used to close the corresponding connecting hole 161 as the water-sealing valve body 3 moves. Among them, the middle sealing ring 34 blocks the connecting hole 161 from the lower part of the partition plate 16 upward. When the user presses the corresponding water sealing valve body 3 by pressing the button 2, the water sealing valve body 3 moves downward, the middle sealing ring 34 is separated from the corresponding communicating hole 161, and water enters from the water inlet channel 6, passes through the water dividing cavity 15 and the communicating hole 161, and enters the corresponding water outlet channel 7. As a preferred solution, there are three groups of water sealing valve bodies 3, which are distributed at 120° in the circumferential direction on the outer side of the linkage disk 4.

[0028] Preferably, the water sealing valve body 3 further includes an upper sealing ring 35 and a lower sealing ring 36. Both the upper sealing ring 35 and the lower sealing ring 36 can be Y-shaped rings. The water diversion body 1 is provided with an upper guide hole 17 and a lower guide hole 18, wherein the upper guide hole 17 is provided at the top of the water outlet channel 7, and the lower guide hole 18 is provided at the bottom of the water diversion chamber 15; the upper sealing ring 35 is provided in the upper guide hole 17, and the lower sealing ring 36 is provided in the lower guide hole 18. Through the above arrangement, the water diversion chamber 15 and the water outlet channel 7 facing each other are formed by the partition plate 16. Since the diameters of the upper sealing ring 35 and the lower sealing ring 36 are the same, and the diameters of the upper guide hole 17 and the connecting hole 161 are also the same, their force-bearing areas in the water are the same. Assuming that the switching valve is in a relatively ideal static pressure state (i.e., all the water outlet channels 7 are closed at the same time), since the thrusts of the water on the upper sealing ring 35 and the middle sealing ring 34 are the same, the water sealing valve body 3 is in a force balance state. Therefore, the key force only needs to overcome the resistance exerted by the elastic deformation of the elastic arm 5 on the positioning groove 32 of the water sealing valve body 3 to push the water sealing valve up and down, and is not affected by the water pressure. The force value of the key 2 is appropriate and stable.

[0029] Combination Figure 6 As shown, in order to ensure smooth rotation of the linkage disk 4, a rotating shaft 19 is provided in the center of the water-dividing body 1, and the linkage disk 4 is arranged in the rotating shaft 19; the track groove 41 is obliquely arranged on the side of the linkage disk 4. A sink groove is provided on the upper surface and / or the lower surface of the linkage disk 4, and a ball 42 is provided in the sink groove, which can reduce the friction force of the linkage disk 4 during the rotation process and ensure smooth rotation of the linkage disk 4.

[0030] The relationship between the stroke L of the spherical body 31 of the water sealing valve body 3 relative to the track groove 41, the pressing stroke H of the water sealing valve body 3 and the inclination angle α of the track groove 41 is si nα=H / L. It can be seen that the surface of the track groove 41 can be set to a straight line around the surface of the linkage disk 4, so that the lifting and lowering of the water sealing valve body 3 is smoother.

[0031] In order to improve the reliability of the elastic arm 5 limiting the positioning groove 32, a convex point 51 is provided at the end of the elastic arm 5, and the convex point 51 can extend into the positioning groove 32. The elastic arm 5 can also be provided with an arc segment 52 to increase the flexibility and fatigue resistance of the elastic arm 5. The cross-sectional shape of the positioning groove 32 can also be an arc shape, so as to match the convex point 51, so that the positioning groove 32 is more smooth when it is separated from and accommodates the convex point 51.

[0032] Preferably, a positioning inclined surface 37 is provided at the lower portion of the positioning groove 32 of the water sealing valve body 3 , and when the water sealing valve body 3 is in the closed position, the convex point 51 abuts against the positioning inclined surface 37 .

[0033] It should be noted that when the water sealing valve body 3 is in the closed position, its main limiting force comes from another water sealing valve body 3 in the open position. This water sealing valve body 3 rotates the linkage disk 4 to a predetermined angle, and the track groove 41 pushes the remaining water sealing valve bodies 3 upward. By adding the positioning inclined surface 37, the elastic arm 5 and the convex point 51 are cleverly used again. The elastic arm 5 pushes the positioning inclined surface 37 through the convex point 51, so that the water sealing valve body 3 generates a constant upward force, which can ensure that the water sealing valve body 3 is pressed against the connecting hole 161.

[0034] like Figure 7 and Figure 8 As shown, preferably, the side of the water sealing valve body 3 is also provided with a positioning rib 38, and the water diversion body 1 is provided with a vertically arranged anti-rotation groove 10, and the positioning rib 38 is arranged in the anti-rotation groove 10 to prevent the water sealing valve body 3 from rotating during the lifting process, thereby avoiding the problem of the spherical body 31 being separated from the track groove 41.

[0035] Finally, the specific embodiment of the utility model also provides a water outlet, which is provided with a linkage switching valve as described above. With the water outlet, the lifting and lowering of the water sealing valve body 3 are controlled by the linkage disk 4. When a certain water sealing valve body 3 descends, the other water sealing valve bodies 3 return to the reset state, ensuring that only one water path is connected at the same time, realizing the water path switching function, and the button switching feels smooth, with a light damping feeling similar to that of an electronic button, and the user experience is good. The elastic arm 5 can reliably fix the water sealing valve body 3 to prevent the water sealing valve body 3 from rebounding under the action of water pressure and closing the water path.

[0036] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the protection scope of the present invention.
