Abstract

L'invention concerne une chambre d'atomisation et une cigarette électronique à ultrasons, un noyau d'atomisation ultrasonore du type cornet (11) utilisé pour atomiser un liquide à vapoter étant agencé à l'intérieur de la chambre d'atomisation ; dans un mode de réalisation de la chambre d'atomisation, l'extérieur du noyau d'atomisation à ultrasons du type cornet (11) est enveloppé par une première couche de guidage de liquide à vapoter (12) en communication avec une cavité de liquide à vapoter ; dans un autre mode de réalisation de la chambre d'atomisation, l'intérieur du noyau d'atomisation à ultrasons (11) est enveloppé par une première couche de guidage de liquide à vapoter (12) en communication avec une cavité de liquide à vapoter (4) ; une plaque d'atomisation (16) est agencée en dessous d'une ouverture sur le fond du noyau d'atomisation à ultrasons (11), une seconde couche de guidage de liquide à vapoter (15), utilisée pour rendre étanche l'ouverture sur le fond du noyau d'atomisation à ultrasons (11) et en communication avec la cavité de liquide à vapoter (4), étant agencée sur le côté supérieur de la plaque d'atomisation (16), la première couche de guidage de liquide à vapoter (12) et/ou la seconde couche de guidage de liquide à vapoter (15) étant remplies de liquide à vapoter ; de la fumée est produite au moyen du noyau d'atomisation à ultrasons (11), puis fumée par l'utilisateur ; la cigarette électronique à ultrasons comprend un couvercle supérieur (2), un couvercle inférieur (3) et un corps de cigarette, le couvercle supérieur (2) étant vissé sur l'extrémité supérieure du corps de cigarette pour rendre étanche l'ouverture de la cavité de liquide à vapoter (4) dans le corps de cigarette. Au moyen de la combinaison du noyau d'atomisation à ultrasons (11) et de la plaque d'atomisation (16), l'appareil selon la présente invention augmente la quantité de fumée, rend les particules de fumée plus fines, améliore la texture et permet le recyclage, ce qui permet d'éviter le gaspillage de ressources.
