摘要： A scent diffusion apparatus and method contains individual original scents for a plurality of scents to be diffused, constructs information on position information of the contained original scents and information on various scents to be diffused in a database, and mixes the original scents of the desired scent properly at a desired point in time based on the scent information, to thereby spray the desired scent. The scent diffusion method includes providing a plurality of scent spraying units containing original scents, heating the original scents via a heater, evaporating the original scents, and diffusing the evaporated scent with the air via an air supply pump. Thus, a desired scent can be transferred to a selected subject under correct concentration. The scent diffusion apparatus uses scent cartridges containing the original scents, such as cartridges used in an existing ink-jet printer, and uses the same control commands as those of a general personal computer or ink-jet printer compatibly. Thus, the scent diffusion apparatus can control an amount of diffusion precisely, be manufactured in a compact fashion, and used in connection with a general purpose computer in which almost all kinds of operating systems supporting an ink-jet printer are incorporated.
