ABSTRACT:
A urinal flushing control device, including a three-way pipe having a first end connected to a water intake pipe, a second end connected to a water outlet pipe through a mixing cylinder, and a third end in the middle mounted with a spring-supported ball valve and connected to an ozonizer. The spring-supported ball valve is drawn inwards by a vacuum suction force when water is discharged from the water intake pipe to the water outlet pipe, to open the passage between the third end of the three-way pipe and the ozonizer, permitting ozone to flow from the ozonizer into the three-way pipe for mixing with water passing therethrough.
