The utility model discloses an inner core type infrared radiation heating aerosol generating system which comprises an infrared radiation heating cigarette rod and a smoke cartridge inserted into theinfrared radiation heating cigarette rod. The infrared radiation heating cigarette rod comprises an infrared radiation heating part, a control part and a battery assembly which are sequentially arranged from top to bottom, and a shell part wrapping the infrared radiation heating part, the control part and the battery assembly into a whole. The infrared radiation heating part comprises a smoke cartridge chamber for inserting a smoke cartridge, an infrared radiation heating column arranged in the smoke cartridge chamber, and a heat insulation part surrounding the periphery of the smoke cartridgechamber; the smoke releasing part of the smoke cartridge is of a hollow structure, so that when the smoke cartridge is inserted into the smoke cartridge cavity, the infrared radiation heating columnis contained in the hollow structure of the smoke releasing part. The system provided by the utility model is uniform and transparent in heating, and overcomes the defects of non-uniform heating, easiness in local overheating carbonization and long preheating time in a resistance type heating technology.
