The device (1) has a reservoir (2) containing odorant liquid (3) i.e. liquid solution comprising fragrance. A spraying unit (4) projects droplets of odorant liquid from a spraying chamber (5), to downstream of a heat exchanger, and is made of piezo-electric element e.g. ceramic or quartz, where the droplets are in the form of a cone (6) having an axis (A). A pulser (7) propels a main air flow (F) inside the chamber, where the main air flow is oriented along a direction (B). The axis of the cone and the direction of the main air flow form an angle ranging from zero to 10 degrees. |
