ABSTRACT:
An automatic air scenting system that introduces a variety of pre-selectable scents into the heating/air-conditioning duct of a motor vehicle or habitable structure comprising a perforated housing, an electric fan for drawing air through the perforated housing, a container of compressed fiber blocks soaked in a scented oil based liquid positioned within the perforated housing, and a hose connecting the housing to the duct of the heating/air conditioning system whereby the fan forces the accumulated scent through the hose into the duct. Automatic functioning is obtained by connecting the fan power lines to the on/off switch and thermostat wiring of the heating/air-conditioning system.
