The invention relates to a toggle valve core, which explains the working process of the toggle valve core by taking the initial state as the closing of a water path. In the initial state, as shown in fig. 6 and 7, the slide carriage 1 is at the left side of the waterway unit, and the positioning protrusion 213 on the assembling portion 21 is engaged with the positioning groove 12 at the right side of the slide carriage 1; the guide block 31 on the switching lever 3 is located at the lower end of the guide groove 11 of the slide carriage 1, the sealing part 33 of the switching lever 3 blocks the pressure relief hole 512, and the water inlet 61 is disconnected from the water outlet 62.
When the state that the waterway is opened needs to be switched, the sliding base 1 is shifted rightwards, the sliding base 1 slides rightwards, the positioning convex part 213 on the assembling part 21 exits the positioning groove 12 on the right side of the sliding base 1 along with the sliding base 1 sliding rightwards, and when the sliding base 1 slides rightwards to the place, the positioning convex part 213 on the assembling part 21 is clamped into the positioning groove 12 on the left side of the sliding base 1, so that the gear feeling is formed. During the sliding process of the sliding seat 1 to the right, the sliding seat 1 drives the switching rod 3 to move upwards through the guide groove 11 of the sliding seat 1 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 be relieved, as shown in fig. 8, and the arrow indicates the water flow direction. As the water pressure chamber 53 is depressurized, the diaphragm 51 is subjected to an upward water pressure, which is greater than the elastic force of the auxiliary spring 52, and the middle portion of the diaphragm 51 is urged away from the top end of the annular boss 63, as shown in fig. 9, so that the water inlet 61 and the water outlet 62 are communicated through the gap between the diaphragm 51 and the annular boss 63, thereby opening the water path.
Under the open state of the waterway, when the waterway is required to be switched to the closed state, the sliding base 1 is shifted leftwards, so that the sliding base 1 slides leftwards, the positioning convex part 213 on the assembling part 21 exits from the positioning groove 12 on the left side of the sliding base 1 along with the leftward sliding of the sliding base 1, and when the sliding base 1 slides leftwards to a proper position, the positioning convex part 213 on the assembling part 21 is clamped into the positioning groove 12 on the right side of the sliding base 1, so that the gear feeling is formed. In the process that the sliding seat 1 slides towards the seat, the sliding seat 1 drives the switching rod 3 to move downwards through the guide groove 11 of the sliding seat 1 to close the pressure relief hole 512 of the diaphragm 51, so that the water pressure in the water pressure chamber 53 is increased, the diaphragm 51 is subjected to downward water pressure, and the sum of the water pressure and the elastic force of the auxiliary spring 52 enables the middle part of the diaphragm 51 to abut against the top end of the annular boss 63, as shown in fig. 6, so that the communication between the water inlet 61 and the water outlet 62 is cut off, and the water path of the valve core is closed.
Compared with a push type switching mechanism, the toggle valve core has the advantages that the switching unit adopts the sliding seat 1 to be matched with the switching rod 3 to control whether the waterway is opened or not, and the sliding seat 1 is toggled to be linked with the switching rod 3 to act, so that the toggle valve core is more intuitive, the toggle force is not influenced by water pressure, the structure is simpler, the toggle valve core is easier to assemble, and the subsequent maintenance is facilitated.
