[0030] The anti-drip principle of this utility model is:

[0031] like Figure 1 As shown, when in use, pressing down on the handle will cause the lever to move upward, and the conical sealing plug will move upward simultaneously, connecting the water inlet with the water outlet at the lower end of the conical shell to allow water to flow out. When the faucet is turned off, the conical sealing plug moves down and presses against the convex edge of the inner wall of the conical shell, while simultaneously covering the annular groove. When water leaks through the conical sealing plug, it will first enter the annular groove. Due to the cooperation between the annular groove opening and the conical sealing plug, the faucet achieves a drip-proof effect.

[0032] To further optimize the above technical solution, a gasket 7 is fixed to the lower end face of the pull rod 3, and a groove is formed on the top surface of the conical sealing plug 8, with the gasket 7 embedded in the groove; the lower end of the spring 4 abuts against the top surface of the gasket 7. The spring is installed through the gasket and the top cover, and the cooperation between the gasket and the conical sealing plug facilitates the replacement of the conical sealing plug. When the handle is pressed, the water flow rate is controlled by the upward displacement of the pull rod and the compression of the spring.
