A scent generating device using powdered fragrance, comprising an air supply device (1), a scent mixing device (2), a feeding device (3) and a powder filtering device (4); the scent mixing device (2) comprises a mixing chamber (21), a turntable (22) disposed within the mixing chamber (21) and a first driving device (23) used for driving the turntable (22) to rotate; an output end of the air supply device (1) communicates with the mixing chamber (21), the feeding device (3) is mounted above the scent mixing device (2), an output end of the feeding device (3) communicates with the mixing cavity (21), and an input end of the powder filtering device (4) communicates with the mixing cavity (21). The turntable (22) within the scent mixing device (2) may separate a powdered fragrance that enters the mixing chamber (21) from the feeding device (3) such that the powdered fragrance may be fully mixed with air that enters the mixing chamber (21) from the air supply device (1), thereby greatly accelerating the process of the powdered fragrance scenting the air. The present invention solves the problem wherein a solid material scenting the air is passive and slow, and effectively solves the problem wherein it is difficult to change the scent within a short period of time. The powder filtering device (4) may filter out powder particles to avoid users feeling there is fine dust in the air.L'invention concerne un dispositif de génération d'odeur utilisant un parfum en poudre, comprenant un dispositif d'alimentation en air (1), un dispositif de mélange d'odeur (2), un dispositif d'alimentation (3) et un dispositif de filtration de poudre (4). Le dispositif de mélange d'odeur (2) comprend une chambre de mélange (21), un plateau tournant (22) disposé à l'intérieur de la chambre de mélange (21) et un premier dispositif d'entraînement (23) utilisé pour entraîner le plateau tournant (22) en rotation.
