Specifically, the assembly part 21 is provided with grooves 214 on the opposite sides of the slide groove 212, respectively, and the grooves 214 are used to provide a space for the positioning protrusion 213 to make way for elastic deformation.

[0048] In this embodiment, the top surface of the assembly portion 21 is provided with limiting structures at both ends corresponding to the sliding direction of the slide 1 to limit the slide 1 from sliding off the assembly portion 21. The limiting structures are specifically limiting ribs 215, but are not limited thereto. When the slide 1 is installed, it is installed to the assembly portion 21 by a certain installation pressure and the plastic elasticity of the slide 1.

[0049] In this embodiment, the sliding cavity 211 and the sliding groove 212 are mutually connected at both ends of the sliding direction of the slide 1. The part of the slide 1 that can be moved is a shift block 13, and the parts of the slide 1 corresponding to the shift block 13 below are, from top to bottom, the slide upper plate 14, the slide neck 15, and the slide body 16. The slide upper plate 14 fits on the top surface of the assembly part 21 and is located between the limiting ribs 215 set at both ends of the top surface of the assembly part 21; the slide neck 15 slides in the sliding groove 212 and is provided with the groove group; the slide body 16 is located in the sliding cavity 211 and is provided with the guide groove 11.

[0050] In this embodiment, the valve core of the present invention is a pilot-operated switch valve core, but it is not limited to this. In other embodiments, when the number of the following diaphragm units is two, the valve core of the present invention constitutes a pilot-operated switch valve core. The water channel unit specifically includes a valve core body and a diaphragm unit 5. The diaphragm unit 5 is installed in the valve core body and cooperates with it to form a secondary water channel. The valve core body is provided with an assembly portion 21 and forms the water channel. The number of the water channel is one, and it is opened or closed according to whether the secondary water channel is opened or not; the switching rod 3 partially extends into the valve core body and controls whether the secondary water channel is opened or not through axial movement.

[0051] In this embodiment, the valve core body is provided with a water inlet 61 and a water outlet 62, and the passage where the water inlet 61 and the water outlet 62 are located constitutes the water circuit; the diaphragm unit 5 and the valve core body form a water pressure chamber 53, and the diaphragm unit 5 is provided with a damping hole 511 and a pressure relief hole 512, and the passage where the water inlet 61, the damping hole 511, the water pressure chamber 53, the pressure relief hole 512 and the water outlet 62 are located constitutes the secondary water circuit; the switching rod 3 controls the opening or closing of the pressure relief hole 512 by moving along its axial direction, and as the pressure relief hole 512 is opened, the secondary water circuit is opened, so that the water inlet 61 is connected with the water outlet 62; as the pressure relief hole 512 is closed, the secondary water circuit is closed, so that the water inlet 61 is disconnected from the water outlet 62.

[0052] In this embodiment, the valve core body specifically includes an upper shell 2, a lower shell 6 and a pressure-bearing inner cover 4. The upper shell 2 is provided with the assembly portion 21 at the top, and the bottom of the upper shell 2 is snap-connected with the top of the lower shell 6. The upper shell 2 is provided with a sealing ring 22 on the outside, the side wall of the lower shell 6 is provided with the water inlet 61, the bottom end of the lower shell 6 is provided with the water outlet 62, and a sealing gasket 8 is installed. The bottom of the lower shell 6 is provided with an annular boss 63 that is connected to the water outlet 62 and extends upward. The pressure-bearing inner cover 4 is installed in the upper shell 2, and a sealing ring 41 is matched between the two. The diaphragm unit 5 is arranged between the pressure-bearing inner cover 4 and the lower shell, and the pressure chamber 53 is surrounded by the pressure-bearing inner cover 4. As the pressure relief hole 512 is opened, the diaphragm unit 5 is separated from the top of the annular boss 63, so that the water inlet 61 is connected with the water outlet 62. As the pressure relief hole 512 is closed, the diaphragm unit 5 abuts against the top of the annular boss 63, so that the water inlet 61 is disconnected from the water outlet 62.

[0053] In this embodiment, the diaphragm unit 5 includes a diaphragm 51 and an auxiliary spring 52. The edges of the diaphragm 51 are limited between the pressure-bearing inner cover 4 and the lower shell 6, and the pressure relief hole 512 is provided in the middle of the diaphragm 51; the auxiliary spring 52 is pressed between the diaphragm 51 and the pressure-bearing inner cover 4, and the top end of the auxiliary spring 52 is bent downward and passes through a through hole provided on the diaphragm 51, so that the gap between the through hole and the end of the auxiliary spring 52 forms the damping hole 511.

[0054] In this embodiment, the top of the switch rod 3 passes through the upper shell 2 upwards and enters the sliding cavity 211, and the switch rod 3 passes through the pressure-bearing inner cover 4, and the two are matched with a sealing ring 7; the lower part of the switch rod 3 passes through the pressure relief hole 512, and the lower part of the switch rod 3 is provided with a sealing part 33, and the switch rod 3 moves axially so that the sealing part 33 blocks or opens the pressure relief hole 512. The sealing part 33 is specifically realized by the corresponding part of the switch rod 3 through the diameter reduction treatment. In addition, a sealing ring can also be set on the switch rod, and the sealing part is formed by the sealing ring.

[0055] In this embodiment, two opposite lugs 32 are disposed on the top of the switching lever 3 , and the guide blocks 31 are respectively disposed on the tops of the opposite inner sides of the two lugs 32 .

[0056] The present invention is a toggle valve core, and its working process is described with its initial state of water circuit closing. Figure 6 , Figure 7 As shown, at this time, the slide 1 is on the left side of the water channel unit, and the positioning protrusion 213 on the assembly part 21 is inserted into the positioning groove 12 on the right side of the slide 1; the guide block 31 on the switching rod 3 is located at the lower end position of the guide groove 11 of the slide 1, and the sealing part 33 of the switching rod 3 blocks the pressure relief hole 512, and the water inlet 61 is disconnected from the water outlet 62.

[0057] When it is necessary to switch to the state of opening the waterway, the slide 1 is pushed to the right to make the slide 1 slide to the right. As the slide 1 slides to the right, the positioning protrusion 213 on the assembly part 21 exits the positioning groove 12 on the right side of the slide 1, and when the slide 1 slides to the right in place, the positioning protrusion 213 on the assembly part 21 is engaged in the positioning groove 12 on the left side of the slide 1, forming a gear sense. In the process of the slide 1 sliding to the right, the slide 1 drives the switch rod 3 to move upward through its guide groove 11 to open the pressure relief hole 512 of the diaphragm 51. At this time, the water in the water pressure chamber 53 flows out through the pressure relief hole 512 to relieve pressure, such as Figure 8 As shown in the figure, the arrow indicates the direction of water flow. As the pressure in the hydraulic chamber 53 is released, the diaphragm 51 is subjected to an upward water pressure which is greater than the elastic force of the auxiliary spring 52 and causes the middle of the diaphragm 51 to leave the top of the annular boss 63, as shown in FIG. Fig. 9 As shown, the water inlet 61 and the water outlet 62 are connected through the gap between the diaphragm 51 and the annular boss 63, thereby opening the water path.

[0058] In the waterway opening state, when it is necessary to switch to the waterway closing state, the slide 1 is pushed to the left to make the slide 1 slide to the left. As the slide 1 slides to the left, the positioning protrusion 213 on the assembly part 21 withdraws from the positioning groove 12 on the left side of the slide 1, and when the slide 1 slides to the left and is in place, the positioning protrusion 213 on the assembly part 21 is inserted into the positioning groove 12 on the right side of the slide 1, forming a gear sense. In the process of the slide 1 sliding toward the seat, the slide 1 drives the switching rod 3 to move downward through its guide groove 11 and closes the pressure relief hole 512 of the diaphragm 51, so that the water pressure in the water pressure chamber 53 increases, and the diaphragm 51 is subjected to the downward water pressure. The sum of the water pressure and the elastic force of the auxiliary spring 52 causes the middle part of the diaphragm 51 to rest against the top of the annular boss 63, as shown in FIG. Figure 6 As shown, the connection between the water inlet 61 and the water outlet 62 is disconnected, so that the water path of the valve core is closed.

[0059] A toggle valve core of the present invention has a switching unit in which the slide 1 cooperates with the switching rod 3 to control whether the water path is open or not. The slide 1 is toggled to link the switching rod 3 to move. Compared with the push-type switching mechanism, the switching unit of the present invention is obviously more intuitive, the toggle force is not affected by the water pressure, and the structure is simpler, easier to assemble, and convenient for subsequent maintenance.
