Abstract

L'invention concerne une cigarette électronique comprenant une cartouche (20) et un ensemble d'atomisation (30). La cartouche (20) comporte une paroi supérieure (21) et une paroi latérale (22). La paroi supérieure (21) et la paroi latérale (22) se referment pour former une cavité de stockage de liquide à vapoter (23), le fond de la cavité de stockage de liquide à vapoter (23) étant ouvert. L'ensemble d'atomisation (30) comprend une tête d'atomisation (31); un canal d'admission d'air (221) est disposé sur la paroi latérale (22) d'un côté de la cartouche (20), et un canal d'évacuation de fumée (222) est disposé sur la paroi latérale (22) de l'autre côté de la cartouche (20). La tête d'atomisation (31) est disposée sur le côté inférieur de la cartouche (20); la tête d'atomisation (31) possède un canal d'atomisation et de chauffage (315), une extrémité du canal d'atomisation et de chauffage (315) étant en communication avec le canal d'admission d'air (221), l'autre extrémité de celui-ci étant en communication avec le canal d'évacuation de fumée (222). Un trou d'admission de liquide à vapoter (3111) est formé sur la paroi latérale de la tête d'atomisation (31), le trou d'admission de liquide à vapoter (3111) étant en communication avec la cavité de stockage de liquide à vapoter (23). Pour la cigarette électronique, la conception intégrale de la cavité de stockage de liquide à vapoter (23), du canal d'admission d'air (221) et du canal d'évacuation de fumée (222) permet une configuration compacte et réduit la difficulté d'assemblage.
