Abstract

L'invention concerne un produit de génération d'aérosol et un système de génération d'aérosol qui appartiennent au domaine technique de la génération de sol. Le produit de génération d'aérosol comprend un boîtier (110) et un ensemble de génération d'aérosol (120). Un canal d'écoulement d'air (131) est disposé à l'intérieur du boîtier (110), une entrée d'air (111) est disposée dans une paroi latérale du boîtier (110), et le canal d'écoulement d'air (131) est en communication avec l'atmosphère externe par l'entrée d'air (111) ; et l'ensemble de génération d'aérosol (120) est disposé à l'intérieur du boîtier (110), le canal d'écoulement d'air (131) est situé en aval de l'ensemble de génération d'aérosol (120), le canal d'écoulement d'air (131) est utilisé pour former un écoulement d'air tourbillonnant sous l'action d'une force d'aspiration de façon à amener un aérosol dans l'ensemble de génération d'aérosol (120), et l'extrémité de l'ensemble de génération d'aérosol (120) qui est éloignée d'un canal d'aérosol (1311) est disposée de manière étanche. Au moyen du produit de génération d'aérosol et du système de génération d'aérosol, l'aérosol peut être évacué dans des conditions dans lesquelles l'air externe ne passe pas dans l'ensemble de génération d'aérosol (120), et l'influence de l'air externe sur la température de chauffage de l'ensemble de génération d'aérosol (120) est évitée, de telle sorte que la température de chauffage de l'ensemble de génération d'aérosol (120) puisse être plus élevée, et l'effet d'atomisation est meilleur.
