Abstract

Abstract An improved toilet stool having an annular conduit seat with intake openings in communication with the inside of the toilet bowl. The improvement being a ventilating means which comprises an adapter plate situated underneath a tank. The adapter plate has a structure defining a conduit which is in communication with the toilet bowl through the intake openings of the seat. A housed filter element is in communication with the conduit seat through the conduit of the adapter plate, and a means is attached to the filter for removing normally contaminated air from the inside of the toilet bowl through the intake openings, the conduit of the adapter plate, and the filter element, in the order stated, for deodorizing the normally contaminated air and passing it into the surrounding atmosphere. A switch means is connected up to the upper rim of the toilet bowl and is operably connected to the means for removing such that pressure exerted on the top of the seat operates the switch means to activate the means for removing.
