2. The inner surface of the carbon cup heating body is provided with the metal foil which separates the carbon cup heating body from the aerosol generating substrate, when the carbon cup heating body is burnt, the waste gas generated by the burning of the carbon cup heating body can not enter the aerosol generating substrate due to the blocking of the metal foil, so that the aerosol generated by heating the aerosol generating substrate can not be doped with the waste gas, the waste gas generated by burning the carbon cup heating body can not be inhaled by a human body, and the harm reduction effect is good.
3.
