The invention discloses a tobacco suction system based on electromagnetic heating, which is characterized in that it comprises an end cover (1), a heater (2) and an electromagnetic induction system, and the end cover (1) is detachably connected to the heater ( 2) above; the end cap (1) includes a round cover (11) and a filter tip (13); the heater (2) includes a shell (21), an inner tank (23) and a chassis (24) and a cylindrical Iron core (25); the electromagnetic induction system includes a heating liner (23), a chassis (24), a cylindrical iron core (25), an induction coil and a temperature control circuit. The present invention can increase the heating speed and high thermal efficiency through the electromagnetic induction system to heat the liner, the chassis and the cylindrical iron core, and can also realize instantaneous heating, so as to better meet the needs of the suction taste; the cylindrical iron core The setting can realize the uniform heating of the tobacco products, so that the tobacco products can be fully heated, which can prevent the waste caused by insufficient heating of the tobacco products, and is suitable for popularization and use.
