Title (EN) AEROSOL GENERATING SYSTEM WITH MULTIPLE INDUCTOR COILS
(FR) SYSTÈME DE PRODUCTION D'AÉROSOL AVEC MULTIPLES BOBINES D’INDUCTION
Abstract:
(EN) There is provided an aerosol-generating device (100) comprising a housing (110) having a chamber (120) sized to receive at least a portion of an aerosol-forming substrate, the chamber defining a heating zone. The aerosol-generating device (100) also comprises a first coil (131, 441) and a second coil (132, 435) disposed at least partially around, or adjacent to, the heating zone. The first coil is a drive coil couplable to a source of alternating current, and the second coil is a resonant coil of a resonant circuit, the second coil being inductively couplable to the first coil. In use, the coils operate to produce an enhanced magnetic field strength to efficiently heat a susceptor located within that magnetic field.
(FR) L'invention concerne un dispositif de production d'aérosol (100) comprenant un boîtier (110) ayant une chambre (120) dimensionnée pour recevoir au moins une partie d'un substrat de formation d'aérosol, la chambre définissant une zone de chauffage. Le dispositif de production d'aérosol (100) comprend également une première bobine (131, 441) et une seconde bobine (132, 435) disposées au moins partiellement autour de la zone de chauffage ou adjacentes à celle-ci. La première bobine est une bobine d'entraînement pouvant être couplée à une source de courant alternatif, et la seconde bobine est une bobine résonante d'un circuit résonnant, la seconde bobine pouvant être couplée de manière inductive à la première bobine. Lors de l'utilisation, les bobines fonctionnent pour produire une force de champ magnétique améliorée pour chauffer efficacement un suscepteur situé à l'intérieur du champ magnétique.
