Abstract

An adjustable air freshener involves a container for a scented gel which includes a heater which is integrally molded within the base of the container with a connecting plug extending outwardly for coupling to an electrical outlet. The front portion of the container includes a rotary cover with a circular configuration having a solid dividing wall on half of the circle extending downwardly to block the flow of hot air from affecting the gel which is positioned between the base and cover within the container. The other half of the cover includes a plurality of spaced apertures which are positioned opposite the heated gel to provide a predetermined scent to the room. The cover and gel may be rotated with respect to the base in predetermined increments to provide the desired scent.
