Abstract (en)

The present invention improves the quality of an experience in which this suction device is used. This suction device comprises: a chamber having a first opening and a second opening; a first generation part which uses a first base material inserted through the first opening and received by the chamber to generate aerosol; a first airflow path which communicates air between a first airflow hole and the second opening; a second airflow path which communicates air between a second airflow hole and the second opening, and in which a second generation part which uses a second base material to generate aerosol is disposed midway; an opening/closing part which opens/closes each of the first airflow path and the second airflow path; and a control part which controls the operations of the first generation part and the second generation part on the basis of the opening/closing states of the first airflow path and the second airflow path.
