  • the cartridge 100 of the present invention may be in an upright state during a user's suction operation, but may be in a lying state or upside down when carrying.
  • the third inflow path 3IR is a symmetrical ring within a 180° range curved along the periphery of the mixing chamber 130, a ring in a 360° range, or a lower side in consideration of both the standing state or the lying state. Needless to say, it can be formed in a spiral structure with a narrower radius.
  • the cartridge 100 is a liquid phase through the configuration of the heater 140 including the heat transfer body 142 of ceramic material and the pressure protrusion 121 of the mouthpiece 120
  • the leakage of tobacco material can be primarily reduced, and leakage of liquid tobacco material is secondarily prevented through the refracted inflow path (IR) formed by assembling the base part 111 and the cover part 112. It can be reduced.
  • IR refracted inflow path
  • the ceramic material heat transfer body 142 the combustion of the wick 132 or the liquid tobacco material due to instant heating is prevented, so that the gaseous phase is harmless to the human body and rich in taste.
  • Tobacco materials can be provided.

Abstract

La présente invention concerne une cartouche comprenant : un embout buccal destiné à permettre à un utilisateur de fournir une force d'inhalation ; un boîtier accouplé à l'embout buccal destiné à fournir un trajet d'entrée d'air et un trajet d'évacuation reliant le trajet d'entrée à un trou d'aspiration, et comprenant un espace de stockage destiné à une substance de cigarette en phase liquide ; une chambre de mélange qui est conçue pour passer à travers l'espace de stockage, relie le trajet d'entrée au trajet d'évacuation, et comprend un ou plusieurs trous de guidage de liquide, qui sont en communication avec l'espace de stockage, et une mèche destinée à recouvrir les trous de guidage de liquide et à aspirer la substance de cigarette en phase liquide guidée à travers les trous de guidage de liquide ; et un dispositif de chauffage destiné à chauffer la substance de cigarette en phase liquide guidée dans la chambre de mélange. Le dispositif de chauffage comprend : un élément chauffant destiné à fournir de la chaleur ; et un élément de transfert de chaleur qui transfère la chaleur de l'élément chauffant à la mèche en recevant une partie ou la totalité de l'élément chauffant, et qui comprend un élément rigide destiné à comprimer une partie de la mèche, laquelle partie correspondant auxdits un ou plusieurs trous de guidage de liquide, de sorte à empêcher la fuite d'une quantité supérieure ou égale à une quantité définie de la substance de cigarette en phase liquide à travers lesdits un ou plusieurs trous de guidage de liquide. Selon la présente invention, la fuite de la substance de cigarette en phase liquide peut être principalement réduite dans la chambre de mélange à travers laquelle est introduite la substance de cigarette en phase liquide, et ainsi, divers problèmes concernant l'hygiène de la cigarette électronique, des dysfonctionnements mineurs, etc. provoqués par la fuite peuvent être résolus. De plus, lorsque l'élément de transfert de chaleur comprend un matériau céramique, la mèche ou la substance de cigarette en phase liquide aspirée dans la mèche ne peut pas être facilement brûlée, et puis une substance de cigarette en phase gazeuse qui n'est pas nocive pour le corps humain et qui possède de riches arômes peut être fournie à l'utilisateur.
