Title
(EN) HEATING ASSEMBLY FOR AN AEROSOL GENERATING DEVICE
(FR) ENSEMBLE DE CHAUFFAGE POUR UN DISPOSITIF DE GÉNÉRATION D'AÉROSOL
Abstract
(EN) A heating assembly (200) for an aerosol generating device (100) is disclosed. The heating assembly (200) comprises: a tubular heating chamber (202) comprising an opening (204) for receiving an aerosol substrate; and a thin film heater (207) that is wrapped around an outer surface (203) of the heating chamber (202) and configured to supply heat to the heating chamber (202). The thin film heater (207) comprises a flexible heating element (208) and a first electrically insulating backing film (206) comprising mica. The flexible heating element (208) is adhesively coupled to a first side (209) of the first electrically insulating backing film (206) and an opposing second side (211) of the first electrically insulating backing film (206) contacts the outer surface of the heating chamber (203).
(FR) La présente divulgation concerne un ensemble de chauffage (200) pour un dispositif de génération d'aérosol (100). L'ensemble de chauffage (200) comprend : une chambre de chauffage tubulaire (202) comprenant une ouverture (204) pour recevoir un substrat d'aérosol ; et un dispositif de chauffage à film mince (207) qui est enroulé autour d'une surface externe (203) de la chambre de chauffage (202) et configuré pour fournir de la chaleur à la chambre de chauffage (202). Le dispositif de chauffage à film mince (207) comprend un élément chauffant flexible (208) et un premier film de support électriquement isolant (206) comprenant du mica. L'élément chauffant flexible (208) est couplé de manière adhésive à un premier côté (209) du premier film de support électriquement isolant (206) et un deuxième côté opposé (211) du premier film de support électriquement isolant (206) est en contact avec la surface externe de la chambre de chauffage (203).
