AIR TREATMENT DEVICE UTILIZING A SENSOR FOR ACTIVATION AND OPERATION

摘要

The present invention provides a system for detecting a malodor and dispensing an air treatment when needed. In an exemplary embodiment of the present invention, the system includes a selection mechanism which allows the user to choose how the system dispenses the air treatment, a sensor, a timing control circuit coupled with the sensor, and a delivery system coupled with the timing control circuit. Upon detection of a malodor by the sensor, the sensor communicates with the timing control circuit which, in turn, communicates with the delivery system to dispense the air treatment. In another exemplary embodiment of the present invention, an air-freshening system is shown that combines a continuous dispensing system with a sensing dispensing system.
