Toilet odor elimination device

Abstract

A toilet odor elimination device that can be retrofitted to existing toilets and adapted for new toilets includes a toilet intake vent located at the rear of the toilet bowl and which is in flow registration with an odor flow tunnel mounted to the inside front wall of the toilet tank for conveying noxious odors to a filter assembly enclosed within the toilet lid, noxious odors also being conveyed through odor intake vents disposed in odor intake channels extending within the lid, for odor purification and filtering by the filter assembly before release back into the room as freshened and scented air with the filter assembly driven by a fan and motor assembly controlled by a cpu unit, and the actuation of the fan and motor assembly from a program setting button on the toilet lid or from a remote control unit with the running time of the fan and motor assembly being set to various time increments from the program setting button or by time setting buttons on the remote control unit.
