Abstract
A high-performance, modular, multipurpose, cartridge-based, liquid dispensing air freshener system that uses at least one refillable or disposable liquid filled cartridge. It can also use fixed tanks and dispense pesticides or any other liquid that can be vaporized. This programmable device can use an unlimited number of cartridges to discharge numerous different fragrances of which can be dispensed separately or mixed. A variety of chassis size and shape configurations can be used, such as a micro-sized unit that allows extreme portability so that it can be used in cars, at office desks or easily carried around in a pocket or purse; it can also function as a compact plug-in air freshener. Cartridges can be automatically selected so that the system can dispense a different scent for different time intervals or mix scents. It can be built into an automotive dash panel or designed to fit into a car style stereo slot.
