  • Lid integrated deodorizer for toilets
    Patent number: 5539937
    Abstract: In a device for eliminating odors from a toilet bowl, a seat and lid appurtenance houses an internal air passage leading from the toilet bowl to the ambient atmosphere. A central lid extension (42 and 64) functions as a backrest and a housing for a motorized fan. A battery housed within the seat energizes the fan which draws foul air from the bowl through a filter for deodorization. Lid vertical instability is overcome through the combination of lid coupling valve (30) and pintles (28) which provides independent and separate seat and lid hinging systems.
