[0048] The positioning sleeve 3 also has a built-in spring 32, and the center bolt 4 passes through the spring 32. The upper end of the spring 32 presses against the center bolt positioning ring 43, and the lower end of the spring 32 presses against the upper end surface of the support seat 3. It is squeezed by the support seat 121 and presents an extruded deformation state in the positioning sleeve 3, so that the center bolt positioning ring 43 can be synchronously pressed against the bottom of the pressure switching device 6 with the center bolt 4; the pressing switching device 6 is formed by a pressing rod 61 and a rotating rod 62, which are sleeved together to form a ballpoint pen telescopic mechanism with the spacer limit strip 132 on the side wall of the pressing limit cavity 13, the center bolt 4 pressed against the bottom of the rotating rod 62, and the spring 32 in the extruded deformation state in the positioning sleeve 3, so as to realize the parking switch of the upper and lower position points of the center bolt 4; the pressing part of the pressing rod 61 is exposed above the valve core upper seat 1;

[0049] The support seat 121 is sealed in the support cavity 12 by a sealing ring 1211;

[0050] The water stop chamber 7 is sealed and assembled by an upper sealing seat 71 and a lower elastically deformable sealing gasket 72, and is sealed and assembled by the valve core upper seat 1 and the lower valve core seat 2. A pair of assembly strips 14 are provided on the outside of the valve core upper seat 1, and an assembly hole 141 is provided on each of the assembly strips 14. The valve core upper seat 1 and the valve core seat 2 assemble all the above structures therein and achieve assembly, wherein the assembly hole 141 of the assembly strip 14 of the valve core upper seat 1 is buckled on the triangular block 222, which is a better assembly method;

[0051] The upper sealing seat 71 and the elastically deformable sealing gasket 72 at the bottom are both provided with a central circular hole adapted to the size of the central pin 4 for the central pin 4 to pass through; the sealing gasket 72 is a one-piece gasket, and the central circular hole adapted to the size of the central pin 4 is further provided with a hollow column 721 extending upward at its center, and a circle of convex rings 722 are provided around the hollow column 721, and a first annular groove 723 is formed between the convex ring 722 and the hollow column 721, and an annular support ring 724 is extended outward from the convex ring 722, and the annular support ring 724 is in the shape of a thin sheet, and the thin sheet-shaped annular support ring 724 is conducive to the elastic deformation and recovery of the sealing gasket 72; the annular support ring 724 is provided with a first annular groove 723, and the first annular groove 723 is formed between the convex ring 722 and the hollow column 721, and the first annular groove 723 is formed between the convex ring 722 and the hollow column 721, and the first annular groove 723 is formed between the convex ring 722 and the hollow column 721, and the first annular groove 723 is extended outward from the convex ring 72 ... One step is connected outwardly with a circle of assembly ring 725 for installation; the hollow column 721 is provided with an upper annular flange 727 and a lower annular flange 728 inside; the central circular hole of the sealing seat 71 is protruding, and overflow notches 712 are provided on both sides of the central circular hole, and overflow notches 712 are also provided around the outer periphery of the sealing seat 71; the hollow column 721 is against the central circular hole of the upper sealing seat 71, and the middle section between the upper annular flange 727 and the lower annular flange 728 of the hollow column 721 has a pair of corresponding transverse guide holes 726 on the side wall of the middle section; the center bolt 4 passes through the central circular hole of the upper sealing seat 71 and then passes through the hollow column 721;

[0052] The central plug 4 has an upper reduced diameter 41 and a lower reduced diameter 42 on the plug body corresponding to the water stop cavity 7. Fig.17 As shown, when the center bolt 4 is located at the upper position point as the pressing switching device 6 is switched, the lower reduced diameter 42 is located at the lower annular flange 728 of the central hollow column 721 of the sealing gasket 72, and a water path 421 leading to the water stop chamber 7 is formed between the lower reduced diameter 42 and the lower annular flange 728. The non-reduced diameter portion of the center bolt 4 blocks the upper annular flange 727 of the central hollow column 721 of the sealing gasket 72. Water flows into the water stop chamber 7 through the water path 421, and is connected to each other through a pair of corresponding transverse guide holes 726 on the side wall of the middle section of the hollow column 721 through the transverse perforation of the center bolt 4. The water flows evenly fills the water stop chamber 7. During the water filling process, the sealing gasket 72 is deformed downward by gravity and seals against the annular convex edge 231 of the valve core seat 2, resulting in the water inlet chamber 23 being closed. The water inlet chamber 23 in the valve core seat 2 is blocked by the water stop chamber 7 and cannot be conducted to the outside, and the water path is closed.

[0053] like Fig.18 , 19As shown, when the center bolt 4 is located at the lower position point as the pressing switching device 6 is switched, a water path 411 leading to the outside of the water stop chamber 7 is formed between the upper reduced diameter 41 and the upper annular flange 727, and the non-reduced portion of the center bolt 4 blocks the lower annular flange 728 of the central hollow column 721 of the sealing gasket 72, so that the water in the water stop chamber 7 is discharged outward along the water path 411, and discharged along the overflow notches 712 on both sides of the central circular hole of the sealing seat 71, and then discharged along the overflow notches 712 around the outside of the sealing seat 71. The water inside the water stop chamber 7 loses water and the sealing gasket 72 is deformed under the action of water pressure, leaving the annular convex edge 231 of the upper outlet of the water inlet chamber 23 of the valve core seat 2. The upper outlet of the valve core seat 2 is opened, so that the water flows through the upper outlet and flows out through the several hollow grooves 24 on the side wall of the valve core seat 2, and the water path in the valve core seat 2 is conducted to the outside, realizing the water path opening.

[0054] The central bolt 4 passes through the second through hole 52 of the rotating plate 5 and rotates in conjunction with the second through hole 52. Fig. 9 As shown, the cross section of the bolt body of the center bolt 4 passing through the second through hole 52 of the rotating plate 5 is non-circular. Figure 7 As shown, the shape of the second through hole 52 is consistent with the cross section. When the center bolt 4 passes through the second through hole 52, the two are matched and fitted, so that the rotating piece 5 can be driven to rotate by the center bolt 4; the center bolt 4 has no linkage relationship with the first through hole 212 of the water stop gasket 21. Figure 2 As shown, the first through hole 212 is larger than the cross-section of the cavity through which the center pin 4 passes.

[0055] When the water channel is open, rotate the flow regulating valve 8 to move the lever 31 and then drive the positioning sleeve 3 to rotate in the rotating positioning chamber 11. Due to the linkage relationship, the positioning sleeve 3 drives the center bolt positioning ring 43, and the center bolt positioning ring 43 further drives the center bolt 4 to rotate, and the center bolt 4 rotates together with the rotating piece 5 below it. Because the rotating piece 5 is tightly fitted with the water-stop gasket 21, and the bottom water-stop gasket 21 is fixed to the bottom of the water inlet chamber 23, therefore, as the rotating piece 5 rotates, the degree of overlap between the water inlet window 211 (fixed) of the water-stop gasket 21 and the fan-shaped adjustment window 51 (rotating) of the rotating piece 5 is affected by the rotation of the rotating piece 5. This can be used to control the size of the water flow from the water inlet window 211 through the fan-shaped adjustment window 51, thereby realizing the adjustment and control of the water flow size.

[0056] With this patented product, users can easily turn the water circuit on and off by pressing, and can also control the water flow by turning the external flow regulating valve 8. It is flexible and convenient to use, and reduces the friction of internal components and the damage caused by wear.
