The invention relates to a soft-touch anti-blockage scale-removal time-delay self-closing water-saving device, which is positioned in a shell body of a domestic water tap, a feces flushing valve, a urine flushing valve or a shower valve, and comprises a button, a valve handle, a cylinder barrel, a piston, a guide holder of the piston, a spring cleaner, a check valve and a water inlet filter screen. Foreign materials in tap water are screened out through the water inlet filter screen so as to prevent blockage; the spring cleaner automatically condenses, passes through and cleans a supercharging hole to prevent scale from forming on the wall of the supercharging hole, prevent the wall of the supercharging hole from being blocked; and the check valve prevents siphoning waste water from being flowed back. When the device is used, the button can be touched lightly by a finger or a tiptoe to automatically close time-delay water consumption. The device has the advantages of simple structure, skillful and convenient use and long service life.
