[0022] Example

[0023] Depend on Figures 1 to 3 As shown, this utility model embodiment provides a push-pull switch valve core, including a valve body 1 and a push-pull switch 5. The valve body 1 is provided with a control component for controlling water output. The control component includes a stationary plate 2, a movable plate 3 movably disposed on the stationary plate 2, and a valve stem 4 for driving the movable plate 3 to move. The valve body 1 is provided with a first connecting part 11. The push-pull switch 5 is slidably connected to the first connecting part 11. The valve stem 4 is hinged in the first connecting part 11 through a rotating shaft. The lower end of the valve stem 4 is connected to the movable plate 3, and the upper end passes through the first connecting part 11 and is connected to the push-pull switch 5 through a connecting rod 6. When the push-pull switch 5 is subjected to force, it can slide back and forth and drive the valve stem 4 to swing through the connecting rod 6, thereby driving the movable plate 3 to move, thus realizing water output control.

[0024] Specifically, the first connecting part 11 has two sliding grooves 12 arranged opposite each other on its outer side, and the push-pull switch 5 has two second connecting parts 51 symmetrically arranged at its bottom. Each of the two second connecting parts 51 has a protruding tooth 52 at its lower end that matches the sliding groove 12. The push-pull switch 5 is slidably connected to the first connecting part 11 through the cooperation of the protruding tooth 52 and the sliding groove 12. A limiting part 53 is provided on the inner side of the second connecting part 51. The bottom of the limiting part 53 abuts against the top surface of the first connecting part 11, thereby limiting the position and preventing the push-pull switch 5 from falling. A limiting contact surface 15 is provided on one of the inner sides of the first connecting part 11. The limiting contact surface 15 is used to limit the rotation of the valve stem 4. Preferably, the inclination angle of the limiting contact surface 15 is 23 degrees. In the initial state, the valve stem 4 abuts against the inner side opposite to the limiting contact surface 15. After the valve stem 4 rotates 23 degrees, it abuts against the limiting contact surface 15.

[0025] In this embodiment, by applying a pushing or pulling force to the push-pull switch 5, the push-pull switch 5 slides back and forth along the sliding groove 12, and drives the valve stem 4 to rotate around the rotating shaft through the connecting rod 6, thereby driving the moving plate 3 to move, thus realizing water outlet control by pushing and pulling.

[0026] The connecting rod 6 has a ball head 61 and a third connecting part 62 at both ends. The bottom of the push-pull switch 5 has a first mounting hole 54 that matches the ball head 62, and the ball head 61 is placed in the first mounting hole 54. The top of the valve stem 4 has a second mounting hole 41 that matches the third connecting part 62, and the third connecting part 62 is accommodated in the second mounting hole 41. The ball head 61 and the first mounting hole 54, and the third connecting part 62 and the second mounting hole 41, are all clearance-fitted, so that when the push-pull switch 5 slides back and forth, the connecting rod 6 can also move back and forth and up and down, thereby driving the valve stem 4 to rotate. In another embodiment, the two ends of the connecting rod 6 can also be connected to the valve stem 4 and the push-pull switch 5 by hinge.

[0027] Furthermore, the upper end of the movable plate 3 is provided with a movable plate cover 31, and the lower end of the valve stem 4 is connected to the movable plate cover 31.

[0028] As a further optimization, the valve body 1 includes a body 13 and an upper cover 14 attached to the body 13, wherein the first connecting portion 11 is disposed on the top of the upper cover 14.

[0029] Furthermore, the valve body 1 is provided with several inlets and several outlets, the stationary plate 2 is provided with several water distribution holes, and the moving plate 3 can block the water distribution holes by movement, thereby allowing the water distribution holes to selectively connect the outlets and the inlets. It is understood that both the moving plate and the stationary plate employ existing technology, and therefore will not be described in detail further.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
