  • the powder supply path 320 is a single columnar powder supply path on the central side of the cross section of the second filter, it is necessary for the rolled up powder to pass through a limited opening area.
  • the powder supply passages are arranged so that the opening regions are dispersed on the outer peripheral side without being concentrated in one place, so that it is possible to increase the delivery amount of the powder during suction.
  • the powder supply passage 320 has an opening width smaller than the size of the powder inclusions 34 .
  • the powder supply path 320 is provided as a through hole of the second filter 32 . If the powder supply path 320 has an opening width larger than the size of the powder containing material 34, the powder containing material 34 may drop off from the stick 1 during the stick 1 manufacturing process or transport process. In the present embodiment, the opening width of the powder supply path 320 is smaller than the size of the powder containing material 34, so the possibility that the powder containing material 34 falls off the stick 1 can be reduced.

Abstract

Un bâton de type chauffage sans combustion (1) comprend : une section de matériau de base (10) comprenant une source d'aérosol ; une unité de refroidissement (20) pour générer un aérosol au moyen du refroidissement de la vapeur générée par chauffage de la source d'aérosol (11) ; et une section de filtre (30). La section de filtre (30) comprend : un premier filtre (31) présent sur le côté de l'unité de refroidissement (20) ; un deuxième filtre (32) présent sur le côté opposé à l'unité de refroidissement (20) par rapport au premier filtre (31) ; et, une substance contenant de la poudre (34) qui est située dans une cavité (33) formée entre le premier filtre (31) et le deuxième filtre (32), est une masse d'une poudre de matière première contenant au moins l'un d'un composant gustatif et d'un composant de parfum, et devient une poudre lorsqu'une force externe est appliquée. Le deuxième filtre (32) est formé avec un trajet d'alimentation en poudre pour fournir de la poudre depuis la cavité (33) vers une extrémité d'orifice d'aspiration.
