[0031] The present invention is further described below in conjunction with the embodiments and the accompanying drawings.

[0032] like Figures 1 to 12 As shown, the present invention provides a flow adjustment structure for a key switch valve core, comprising a slide buckle 1, a flow control cover 2, a flow positioning ring 3, a limit ring 4 and a key switch valve core 5.

[0033] A control end 15 is provided on the top of the key switch valve core 5. The key switch valve core 5 controls the opening and closing of the valve core by pressing the control end 15. A control end groove 16 is provided below the control end; a valve core transmission thread 18 is provided on the outer wall of the key switch valve core 5, and a valve core limiting groove 17 is provided above the valve core transmission thread 18. A slide groove 6 is provided on the upper end of the flow control cover 2, and a limiting boss 7 is provided on the inner wall of the slide groove 6. An inner slideway 9 and a positioning buckle 8 are provided at the lower end of the flow control cover 2, and a gourd hole 14 is provided on the slide buckle 1. A convex edge 13 is provided at the edge of the slide buckle 1, and the slide buckle 1 is placed in the slide groove 6 of the flow control cover 2. The convex edge 13 is located below the limiting boss 7. After being limited by the limiting boss 7, the control end 15 of the button switch valve core 5 passes through the gourd hole 14; at this time, the slide buckle 1 is slid to make the small hole end of the gourd hole 14 slide into the control end groove 16, buckle the control end 15, and connect the flow control cover 2 and the control end 15 together (the slide buckle 1 can also be replaced with other connection methods such as screws to directly connect the flow control cover and the control end together).

[0034] like Fig.10 As shown, a positioning boss 10 is provided on the upper end of the flow positioning ring 3, a slide boss 11 is provided on the outer wall, and a positioning ring transmission thread 12 is provided on the inner wall of the bottom. When the flow positioning ring 3 is rotated, the positioning ring transmission thread 12 cooperates with the valve core transmission thread 18, and the flow positioning ring 3 will translate along the central axis of the valve core; the slide boss 11 of the flow positioning ring 3 is restricted to slide in the inner slide 19 of the flow control cover, and the positioning boss 10 is buckled into the positioning buckle 8; through the cooperation of the slide and the buckle position, the rotating flow control cover 2 can drive the flow positioning ring 3 to rotate together, and at the same time, the flow positioning ring 3 can drive the flow control cover 2 to move together through the buckle position; the limit ring 4 is buckled into the valve core limit groove 17 to prevent the flow positioning ring 3 from falling out and limit the range of up and down movement of the flow positioning ring 3.

[0035] like Fig.11 As shown, rotating the flow control cover 2 in one direction drives the flow positioning ring 3 to rotate, and the flow positioning ring 3 can drive the flow control cover 2 to move together by buckling, so as to limit the highest position of the flow control cover 2 connected to the valve core control end 15 at this time, that is, by limiting the highest position of the valve core control end 5, the purpose of adjusting the water outlet flow of the key switch valve core 5 at this time is achieved.

[0036] like Fig.12 As shown, the flow control cover 2 is directly pressed, and the flow control cover 2 and the flow positioning ring 3 slide relative to each other, and the flow control cover drives the control end 15 to move downward until it reaches the switching position, closing or opening the valve core.

[0037] For most push-button switch valve cores, when the control end 15 is slowly pressed during the pressing stroke from opening to closing, the flow rate of the valve core will gradually decrease and eventually close; that is, for most push-button switch valve cores, the water flow rate of the valve core can be controlled by adjusting the stroke of the control end 15. The present invention utilizes the characteristics of the push-button switch valve core and realizes the flow regulation and switching functions only through the flow control cover. It can be adapted to most common push-button switch valve cores on the market, saving the cost of additional design and mold opening for a special flow regulating push-button switch valve core.

[0038] The examples of the present invention are described in detail above, but the present invention is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. All changes and improvements made within the scope of the present invention are still within the protection of the present invention.
