Abstract (en)
The present disclosure relates to the field of novel cigarette smoking utensil, and in particular, to a smoke generating device with induction heating in a folded airway. The smoke generating device includes: a cigarette introduction pipe (1), an induction coil (3), a heating cup (5), a heating element (6) and a magnetic sealing element (7); wherein the cigarette introduction pipe (1) is disposed at the upper end of the smoke generating device with a hollow tubular structure, and its internal cavity is an air-mixing cavity (1D), the diameter of the air-mixing cavity (1D) is greater than that of the inner cavity of the heating cup (5), a gap is provided between the inner wall of the cigarette introduction pipe (1) and the upper end of the heating cup (5) as an air inlet channel (1A). The present disclosure folds the original "heating body + cigarettes" with a reduced space axial length, so as to reduce the axial length of the heating part of the smoke generating device. The heating element (6) of the present disclosure is disposed in the airway in a folded reciprocating form, which not only increases the length of the airflow channel, but also reduces the axial length of the smoke generating device.
