Abstract

Abstract An improved air freshener dispenser is activated by the signal transmitted along a home doorbell actuation line. The air freshener is located at a convenient location for spraying an amount of an aerosol air freshener into an entry or desired public area of a home or house. The actuation mechanism is connected to the doorbell system for the house. In operation a guest, or other person entering the home, will in practice ring the doorbell releasing a metered amount of the aerosol air freshener which will have had time to disburse throughout the area concerned at approximately the time the guest enters.
