Abstract: An electronic vaporization device for heating and vaporizing an aerosol-forming substrate includes: a vaporization cavity for accommodating the aerosol-forming substrate; a microwave generating circuit for generating a microwave according to a preset microwave frequency; a microwave transmitting antenna connected to the microwave generating circuit for sweeping and transmitting the microwave within a preset microwave frequency range, and transmitting the microwave to the vaporization cavity to heat the aerosol-forming substrate; a feedback acquisition circuit for acquiring a feedback signal corresponding to the microwave of the preset microwave frequency that is transmitted by the microwave transmitting antenna; and a microwave control circuit connected to the microwave generating circuit and the feedback acquisition circuit, respectively, the microwave control circuit determining the preset microwave frequency and control the microwave generating circuit to generate the microwave according to the preset micr

Abstract: A heating assembly applied to an electronic vaporization device includes: a ceramic substrate; and a heating layer including stainless steel and inorganic non-metal. The heating layer heats a substrate to be vaporized to form an aerosol and has a temperature coefficient of resistance (TCR) temperature-sensitive characteristic. The inorganic non-metal adjusts the TCR of the heating layer.
