PURPOSE: To enable quick and stable performance of scent by providing a vibration generating means which vibrates a tubule to match a discharge timing of a fragrant liquid to allow the lingering of the fragrant liquid highly viscous with a lower surface tension in the air without falling.
CONSTITUTION: When an electric signal 10 is inputted into a heat generating sction 9 with a drive control circuit within an air conditioning apparatus through a remote control or the like, a heat generating section 9 as part of a tubule 9 is heated sharply so that a fragrant liquid 2 in the tubule 8 is vaporized by boiling from a wall surface and a gas begins to generate. Then, simultaneously with the inputting of the electrical signal 10 into the heat generating section 9, an AC signal of several ten km to several MHz is applied to a piezo-electric vibrator 11 from a pieze-electric drive circuit 12 to apply a fine vibration to a nozzle 7. As a result, a pressure generated works on the side of the nozzle 7 with a short tube length and a small fluid resistance and a liquid pillar of the fragrant liquid 2 is extruded from the nozzle 7. But the application of the vibration to the nozzle 7 allows the liquid pillar to be divided into fine liquid drops corresponding to a frequency immediately.
