Flush control system of a ballfloat toilet

Abstract

The ballfloat toilet flush control system includes a master flush handle, a discharge valve controlled by the master flush handle, a float slidably mounted to a float holder, an air tube connected between an 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. The auxiliary flush handle has an axle spaced from the bottom end of a control member of the passage control device, and moved upwards to force the control member of the air passage control device into engagement with a retaining groove on the supporting frame of the float holder when the auxiliary flush handle is depressed. A locating shell is fixedly mounted inside the water tank to hold the float holder, having a sleeve sleeved onto the shaft of the float to guide its movement and a stop block to limit the upright movement of the upright hollow shaft of the float; the upright hollow shaft of the float is vertically adjustably fixed to the float by a tightening up screw so that the elevation of the upright hollow shaft can be adjusted by loosening the tightening up screw.
