Sanitary device for urinal and toilet flush system

Abstract

A flush system for toilet, urinal or the like includes a valve body having a water inlet, a water outlet, and a water chamber, a valve seat, an actuation device, and a sanitary device. The sanitary device includes a container body mounted on the valve body for replaceably receiving a sanitary agent therein. The container body has a lower sanitary opening communicating the container body with the water outlet of the valve body. When the valve seat is in a flushing position, a portion of the flush water is guided to flow into the container body through the sanitary opening for mixing with the sanitary agent so as to form a cleansing solution. After the valve seat is returned to an idle position, the cleansing solution is released by gravity for flowing towards the water outlet through the sanitary opening to sanitize the toilet, urinal or the like.
