Abstract
A timed aerosol fragrance dispenser includes a housing containing a programmable microprocessor, a low-voltage DC power source, a piezoelectric assembly for spraying timed bursts of fragrance, and circuitry for activating the piezoelectric assembly, and a magnetic reed switch air flow detector. A fragrance-containing reservoir attaches to the housing, which incorporates a clip which allows the dispenser to be secured to a heating and air conditioning vent register. When the air flow detector senses air flow from the vent register, the microcontroller in combination with other circuitry generates current pulses having a voltage sufficiently high to activate the piezoelectric assembly. Intervals between pulses are switch selectable. In addition, the normal programming can be overridden to spray fragrance for a set period even in the absence of air flow from the vent register.
