Description

Technical Field

[0001] The utility model relates to a valve core. Background Art

[0002] The existing push-to-switch valve core itself does not have the flow adjustment function. When consumers need the flow adjustment function, they need to separately add a valve core with the flow adjustment function. This makes the water path structure complicated and the cost of adding the valve core increases significantly, and the operation is also cumbersome. For constant temperature push-to-switch faucet products, since the thermostatic valve itself does not have the closing function, a switch valve needs to be separately added to shut off the water flow. This makes the water path structure complicated and the cost of adding the valve core increases significantly, and the operation is also cumbersome. The push-to-switch shower column product itself does not have the closing function, which requires consumers to close the temperature control valve when applying the liquid in the shower. However, since the liquid interferes with the eyes, when the temperature control valve is reopened, the temperature fluctuates and needs to be readjusted. The operation is troublesome and there is a risk of scalding. Summary of the Invention

[0035] More specifically, the present invention utilizes separate control for function switching and flow regulation: function switching is achieved by pressing, while flow control is achieved by rotating. Pressing the stator drives the movable shaft to move axially, achieving function switching; rotating the shaft drives the movable ceramic disc to move in a circular motion, achieving flow regulation. When the water holes of the movable ceramic disc and the fixed ceramic disc are completely misaligned, no water will flow because the water cannot enter the water passage. When the water holes of the movable ceramic disc and the fixed ceramic disc overlap, the water flow rate is altered by the overlapping area, thereby achieving flow regulation.

As previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the present invention as taught herein or through the techniques or knowledge of the relevant art. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the claims appended hereto.
