PURPOSE:To make pleasant perfume present in a space for a long time by making the closing valve of a perfume container containing aromatics opened/ closed intermittently every specified time, and the thereby injecting perfume intermittently into a cabin. CONSTITUTION:The roller 71 of a drive device 7 is rotated intermittently every specified time, then, when a perfume card 4 containing aromatics 41 is advanced in a card leader 1 so as to let the topmost end of it be moved to the position of a photo-electric sensor 53, the valve closing gear 3 of the perfume card 4 is pushed by an injection shaft 13 at the tip end of the card leader 1 so that a nozzle head section 22 is pulled out forward, and the valve 24 of an injection valve 2 is also pulled out forward so as to let perfume gas be injected from the nozzle head section 22. After the injection has been kept on for a certain period of time, the card 4 is retreated with the press by the injection shaft 13 released so that injection is suspended. Moreover, the perfume card 4 is inserted into the card leader 1 from an opening section 16 so that the set position of it is ascertained by photo-electric sensors 51 and 52. By this constitution, fresh perfume can thereby be enjoyed at all time. |
