ABSTRACT:
Disclosed is a set of bad odor removing stool seat and seat cover that can be mounted on any conventional toilet bowl to function immediately. The stool seat has an internal channel that is communicable with a space in the toilet bowl via a plurality of openings spaced along an inner periphery of the stool seat. A hollow tubular portion is formed at a rear end of the stool seat to serve as a shaft for the seat cover to pivotally connected thereto. The hollow tubular portion defines an inner space communicable with the internal channel. A fan motor, filters, and a fragrant agent are sequentially mounted in the tubular portion from inner side to outer side of the tubular portion. When the fan motor is switched on, bad odorous air in the toilet bowl is drawn into the internal channel via the openings spaced on the stool seat to pass the filters and the fragrant agent, so that bad odor is removed from the air and the air is further freshened and scented before it is discharged from the tubular portion.
