ABSTRACT:
A toilet disinfectant release apparatus includes a housing disposed and supported inside a toilet tank by a U-shaped hanger fitting over a side wall of the toilet tank, into which housing a disinfectant supply control device is mounted. The housing has a convex rim mating a complementarily-shaped edge of an externally mounted disinfectant container to soundly hold the container and allows an opening of the container inserted into the housing. The supply control device has a disinfectant chamber in fluid communication with a piston shaft which has a piston movably received therein. The movement of the piston changes the volume and interior pressure of the disinfectant chamber so as to draw in disinfectant from the disinfectant container and/or inject the disinfectant so drawn in into the housing from a one-way nozzle mounted to the supply control device. The disinfectant so injected mixes with water within the housing and then released to the toilet tank. The movement of the piston is controlled by a buoy which has a rod extending therefrom to connect to the piston. The buoy is in turn moved up and down by water inside the toilet tank and thus the piston moves to and fro once at each time the toilet is flushed so as to draw from the disinfectant container a substantially constant amount of disinfectant into the disinfectant chamber and inject the amount of the disinfectant into the toilet tank.
