Abstract:
1. A gaseous constituent supply device for supplying an air vortex ring containing a gaseous constituent, the device comprising: a first chamber holding the gaseous constituent therein, and having an opening, through which air containing the gaseous constituent is blown; a compressing portion for compressing air in the first chamber so as to blow air from the first chamber through the opening; a second chamber communicating with the first chamber through the opening, and a partition wall partitioning the first chamber and the second chamber from each other, wherein the second chamber holds the gaseous constituent therein, and has an emitting outlet provided opposite to the opening of the first chamber, the second chamber generates the air vortex ring by air blown from the first chamber through the opening while taking in the gaseous constituent, the second chamber emits the generated air vortex ring through the emitting outlet the opening of the first chamber is provided in the partition wall and is open to the second chamber, the emitting outlet of the second chamber is positioned opposite from the opening of the first chamber, the second chamber is a space defined between the partition wall and the emitting outlet; the opening of the first chamber has a first round shape, the emitting outlet of the second chamber has a second round shape, and the first round shape and the second round shape have approximately the same axis which is perpendicular to the partition wall.
