ABSTRACT:
An air deodorizing apparatus for circulating and filtering air within a flush tank and bowl of a toilet includes a fan, annular air filter, and housing mounted within the toilet flush tank. The fan has a motor with a rotary output shaft and a fan blade mounted to the shaft and rotatable therewith for inducing a flow of air past the motor upon operation of the motor. The housing is mounted on an upper end of an overflow tank in the toilet flush tank. The housing supports the fan in axially aligned relation with the overflow pipe and mounts the annular air filter in concentric relation around the fan motor with the fan blade rotatable adjacent to the air flow inlet side of the annular filter. The apparatus also has an electrical power supply and switch connected to the fan motor and operable for controlling operation of the fan.
