ABSTRACT:
A toilet deodorizer having a hollow housing, containing a motor-driven fan and a filter medium, mounted within the normal flush tank air chamber. The housing divides the air chamber into an intake receptacle, inside the housing, and an exhaust receptacle, outside the housing. The intake receptacle is open to the overflow conduit through an inlet aperture, and is open to the exhaust receptacle through an outlet aperture. The fan induces air from the closet bowl through the overflow conduit, and thence through the filter into the exhaust chamber, thereby deodorizing the closet bowl.
