Abstract

Le présent modèle d'utilité concerne un atomiseur et un appareil de génération d'aérosol. L'atomiseur comprend un composant de stockage de liquide, un noyau d'atomisation et un composant tube de ventilation. Dans une structure de l'atomiseur, une première extrémité du composant tube de ventilation est reliée à une ouverture d'inhalation, et une seconde extrémité du composant tube de ventilation est emmanchée sur un côté externe d'un support d'atomisation, ce qui peut améliorer la stabilité entre le composant tube de ventilation et le support d'atomisation et réduire la possibilité d'espaces d'assemblage entre le composant tube de ventilation et le support d'atomisation, réduisant ainsi le risque de fuite de liquide. De plus, un bouchon est disposé sur le support d'atomisation, et lorsqu'il est pressé contre la seconde extrémité du composant tube de ventilation, le bouchon peut limiter le coulissement du composant tube de ventilation par rapport au support d'atomisation, ce qui permet d'améliorer davantage la stabilité entre le raccord de tuyau de ventilation et le support d'atomisation, ce qui peut empêcher des espaces d'assemblage entre le composant tube de ventilation et le support d'atomisation. En même temps, le bouchon peut également recouvrir une ouverture d'extrémité de la seconde extrémité du composant tube de ventilation, pour obtenir l'effet d'étanchéité de l'orifice d'extrémité de la seconde extrémité du composant tube de ventilation, ce qui permet d'empêcher efficacement une fuite de liquide et d'améliorer l'expérience utilisateur.
