Abstract
The ballfloat toilet flush control system comprised of a master flush handle, a discharge valve controlled by the master flush handle, a float pivoted to a float holder on the overflow tube of the ballfloat toilet, an air tube connected between the air chamber of the discharge valve and an air passage on the float holder, an auxiliary flush handle, and an air passage control device controlled by the auxiliary flush handle, whereby the air passage control device tops the air passage, permitting water to be completely drawn out of the water tank of the ball float toilet as the master and auxiliary flush handles are simultaneously pressed; the air passage control device opens the air passage to let water enter the air chamber of the discharge valve so that the discharge valve stops the water outlet of the water tank before water is completely drawn out of the water tank when only the master flush handle is pressed.
