Combined electromagnetic induction aerosol heating device

Abstract

The invention provides a combined electromagnetic induction aerosol heating device. The combined electromagnetic induction aerosol heating device comprises a shell, a heating cavity arranged in the shell, an electromagnetic heating coil used for generating an alternating magnetic field and an electromagnetic heating magnetized body. The electromagnetic heating magnetized body is placed in an alternating magnetic field generated by the electromagnetic heating coil and used for generating eddy current and raising the temperature, and the electromagnetic heating magnetized body is provided with a plurality of magnetized areas with different magnetic permeability in the axial direction of the electromagnetic heating coil, so that different magnetized areas generate different electromagnetic heating amounts. The electromagnetic heating magnetized body is composed of magnetized areas with at least two magnetic conductivities, and a heat insulation ring for preventing heat conduction is arranged between every two adjacent magnetized areas. The induced electromotive force produced by the magnetized region with different permeability in the same alternating magnetic field is different, so that the electromagnetic heating magnetized body composed of the plurality of magnetized areas with different magnetic conductivities can generate a plurality of heating sections with different temperatures so as to realize segmented heating of an aerosol generating substrate.

Description

Technical field [0001] The present invention relates to the technical field of new tobacco products, and more particularly to a combined electromagnetic inductive aerosol heating device. Background technique [0002] Induction heating means that alternating current generated by induction heating power is generated by the sensor, that is, the coil, the magnetic material, is placed therein, thereby causing the alternating current to generate an alternating current, eddy current, inside the object Atomic high speed is random motion, atoms collide with each other, friction and heat energy, resulting in the effect of heating items. [0003] Public document CN108991603A discloses a multi-stage electromagnetic induction heating system for low temperature tobacco, which is a multi-stage electromagnetic inner wall of the present invention with multi-stage electromagnetic sensing heating system. The outer shield is outside the inner wall, several electricity The magnetic induction heat sou...

Problems solved by technology

The multi-stage electromagnetic induction heating system for low-temperature tobacco adjusts the heating temperature of different segments by separately controlling the input voltages of several independent electromagnetic induction heat sources to realize segmental heating. The design and operation of separately adjusting the input voltages of several independent electromagnetic induction heat sources are relatively complicated. less practical

[0004] Most of the susceptors designed in the prior art use a single material, and can only produce a single heating temperature under the induction of the same alternating magnetic field. The design structure of this susceptor is single and simple, but in actual use, due to the suction of the air The heating temperature of the downstream end of the airflow close to the filter tip of the aerosol-generating matrix is ​​relatively high, resulting in problems such as insufficient heating and low material utilization due to uneven heating of the aerosol-generating matrix
