Fan-Driven Air Freshener
First Claim
1. An air freshener apparatus for a robotic vacuum cleaner comprising:
- a reservoir containing a chemical;
a triggering circuit controlled by the robotic vacuum cleaner;
a fragrance delivery system comprising a plurality of fragrance chemicals volatilized by a microfluidic dispersal system;
a fan assembly comprising a fan and a fan motor disposed in a housing adjacent the reservoir that is controlled by the triggering circuit; and
an outlet duct directing scented air from the fan assembly, wherein the fragrance delivery system is by the triggering circuit.

Abstract
An air freshener that has a source of air freshening chemical with a fan that is controlled either by an optical device that senses light or a motion detector is disclosed. When a light is turned on or motion is detected, the fan will be activated for a predetermined time period. In certain embodiments, the fan will stop turning after a predetermined time. In certain preferred embodiments the source of air freshening chemical is disposed beneath the fan and allows fragrance to be delivered over time without the fan. The additional airflow provided by the fan causes more volatile fragrance chemicals to be removed from the source of air freshening chemical and admitted into the environment. Preferably, a microprocessor controls the fan so that a “burst mode” is created by controlling the frequency and intensity of the pulses of air freshener that are emitted. Also disclosed is a system for delivering a volatilized chemical integrated into a robotic vacuum cleaner. A reservoir of volatile chemicals, such as a fragrance, is volatized and exhausted by the fan stream through an exhaust duct. As the robotic vacuum cleaner carries out its automated routine, it adds a scent, antibacterial chemical or other chemical to the surface being cleaned, e.g., carpeting.
