Toilet flush control device

摘要

A patented valve control for use in a toilet tank having a bottom outlet for discharging water to a toilet bowl, a valve for closing the outlet, a conventional actuating lever and a chain connecting the lever to the valve for opening the latter, includes an arm carrying the valve pivotally mounted in the toilet tank for actuation by the chain to open the bottom outlet, a float on the arm biasing the valve to the open position when the tank is full and biasing the valve to the close position when the tank is empty, and a drainable container on the arm biasing the valve open when the latter is open and biasing the valve closed when the latter is closed. The amount of water discharged through the outlet during each flushing operation can be reduced by mounting a flush control device on the arm of the valve control. The flush control device is a rectangular parallelepipedic body with a groove in one side thereof for mounting the body on the arm. A slot extends into the groove from one end of the body for facilitating mounting of the body on the arm. The body changes the turning moment on the arm to close the valve before all of the water has been discharged from the tank. Thus, the quantity of water discharged from the tank to the toilet bowl during each flushing operation can be reduced.
