Referring to fig. 1-2, in one embodiment of the utility model, a heating device 100 is provided, the heating device 100 being used in an electronic atomisation device for heating an aerosol-generating substrate for atomising flowers, herbs or pastes.
The heating device 100 comprises a base 10, an electromagnetic coil 30 and an infrared radiation piece 50, wherein the base 10 is provided with a heat insulation cavity 11 and an accommodating cavity 13 which are mutually independent and adjacent, the electromagnetic coil 30 is arranged on the base 10, and the infrared radiation piece 50 is arranged in the heat insulation cavity 11. The infrared radiation member 50 includes an induction body 52 and an infrared radiation layer 54, the induction body 52 being configured to generate heat by electromagnetic induction of the electromagnetic coil 30; the infrared radiation layer 54 is coated on a surface of the inductor 52 facing the receiving chamber 13, and is configured to absorb heat of the inductor 52 and radiate infrared rays to a body to be heated in the receiving chamber 13. After the electromagnetic coil 30 is energized with alternating current to form a magnetic field, the inductor 52 generates heat under the action of electromagnetic induction, so that the infrared radiation layer 54 coated on the inductor 52 is heated and radiates infrared rays to the accommodating cavity 13, and the aerosol generating substrate in the accommodating cavity 13 is heated by the infrared rays to atomize the aerosol generating substrate.
The inductor 52 of the infrared radiation member 50 is disposed in the thermal insulation chamber 11 and spaced apart from the wall of the thermal insulation chamber 11 to assemble the infrared radiation member 50 in a thermal insulation manner. When the inductor 52 generates heat under the action of the electromagnetic coil 30, the infrared radiation piece 50 generates heat as a whole, but the infrared heating piece and the inner wall of the heat insulation cavity 11 are arranged at intervals, so that heat cannot be directly transferred to the base 10, and the aerosol generating substrate in the accommodating cavity 13 is prevented from being scorched due to overhigh heat of the base 10. Furthermore, the provision of insulation within the insulated cavity 11 prevents heat generated by the infrared radiation member 50 from being transferred to the base 10 through the interior of the insulated cavity 11, further preventing the base 10 from rising in temperature and burning the aerosol-generating substrate. In this way, the aerosol-generating substrate in the accommodating cavity 13 is heated only by the infrared rays radiated by the infrared radiation layer 54, so that high-temperature baking can be provided at the initial stage of smoking in a maximized manner by using an infrared heating mode, and meanwhile, the aerosol-generating substrate is not burnt by heating the base 10, thereby reducing the preheating time of the aerosol-generating substrate and ensuring the smoking taste.
In addition, the infrared heating advantage is fully exerted, the aerosol generating substrate can be heated at high temperature in a short time, more short-wave-band media can be atomized, and the atomization mouthfeel is enriched. In addition, the electromagnetic heating mode only needs to arrange the electromagnetic coil 30 on the seat body 161, and a heating film layer does not need to be manufactured on the atomizing core, so that the manufacturing of the atomizing core is simplified.

In other embodiments, the thermal conductivity of the gas filled in the insulating chamber 11 is less than the thermal conductivity of air, i.e. the thermal conductivity of the gas in the insulating chamber 11 is lower, e.g. the insulating chamber 11 is filled with a halide gas, and the thermal radiation emitted by the infrared radiation element 50 is less transmitted to the susceptor 10 through the gas in the insulating chamber 11, preventing the susceptor 10 itself from being too hot to burn the aerosol-generating substrate.

For example, the through holes 51 are opened in plural, and each through hole 51 extends in the first direction.
