PURPOSE:To prevent the generation of uncomfortable odor even if plural kinds of perfumes are supplied alternately and permit easy replacement of perfumes by installing an aromatic damper between each aromatic unit and a aroma feeding duct with which the aromatic unit is connected and installing a deodorant unit and a deodorant damper on the aroma feeding duct. CONSTITUTION:The aromatic damper MD1 of an aromatic unit U1 is opened, and the aromatic units U2 and U3 and the aromatic dampers MD2-MD4 of a deodorant unit U are closed, and the air in a aroma feeding duct 7 is sent into a living space 1 by a fan 8. Then, the air sucked from the air suction port 14 of the aromatic unit U1 contacts the perfume pack 12 in a case body 10, introduced by the air stream, and flows into a perfume feeding duct 7, passing through a perfume blow-out port 13, and aroma is sent from a aroma feeding port 5. Then, the aromatic damper MD1 is closed, and the damper MD4 of the deodorant unit U is opened in substitution, and the deodorant and neutralizer are introduced into the aroma feeding duct 7, and sent from the aroma feeding port 5. Similarly, the next aromatic unit U2 and the deodorant unit U are opening/closing-controlled.
