Abstract

L'invention concerne un dispositif de prévention de fuite (10, 20, 30, 40, 50, 60, 70) pour une cigarette électronique. Le dispositif comprend un boîtier (11, 21, 31, 51, 61, 71), un canal d'écoulement d'air (12, 22, 32, 42, 52, 62, 72) permettant à un écoulement d'air et/ou de la fumée de passer à travers ce dernier, et une structure poreuse absorbant un e-liquide et empêchant une fuite de e-liquide à l'aide d'une action capillaire. Le canal d'écoulement d'air (12, 22, 32, 42, 52, 62, 72) est formé à l'intérieur du boîtier (11, 21, 31, 51, 61, 71). La structure poreuse comprend une plaque poreuse (13, 23, 33, 43, 53, 63, 73) disposée à l'intérieur du canal d'écoulement d'air (12, 22, 32, 52, 62, 72). Au moyen de l'effet capillaire dans les petits pores, le dispositif absorbe un e-liquide dans le canal d'écoulement d'air en utilisant la structure poreuse dans le canal d'écoulement d'air, empêchant ainsi efficacement la fuite d'un e-liquide d'une cigarette électronique tout en assurant une ventilation suffisante.
