INDUCTION HEATING DEVICE Russian patent published in 2020 - IPC A24F47/00 A61M15/06 

FIELD: smoking accessories.

SUBSTANCE: invention relates to tobacco industry, more specifically to induction heating device for electronic cigarette. Disclosed is an induction heating device for use with a smoking material heating device for evaporation of at least one component of said smoking material. Induction heating device comprises a receiving element, at least a first induction coil and a second induction coil and a control circuit for said coils. Sensing element is heated by penetration of an alternating magnetic field for smoking material heating. First induction coil is configured to generate a first variable magnetic field for heating a first portion of a sensing device, and the second induction coil is intended for generation of the second variable magnetic field for heating of the second section of the receiving device. Control circuit is configured such that if one induction coil actively generates alternating magnetic field, then another inductance coil is inactive, and wherein the control circuit is configured to prevent leakage in the inactive induction coil of current induced by the active induction coil, sufficient to cause significant heating of the sensing device.

EFFECT: technical result is possibility of smoking material evaporation by heating without burning.
