  • the heating methods currently used in heat-not-burn cigarettes mainly include inner core heating and outer core heating.
  • the inner core heating method the heat is concentrated inside the tobacco, resulting in insufficient baking of the outer tobacco, and the tobacco utilization rate is not high.
  • the inner core heating element is in contact with the tobacco, and is easy to stick together after heating, causing the tobacco segment to fall into the heating device when the cigarette is pulled out.
  • Peripheral heating is achieved by setting a heating element on the inner wall of the cigarette holding cavity of the electric heating device, and heat is transferred from the outer periphery of the tobacco segment to the inner part.

  • Air-heating type smoking utensils introduce air as a heat transfer medium. Because the heating body is not in direct contact with the smoke-generating substance, the problem of fouling and difficulty in cleaning the inner core heating plate is solved; at the same time, because the hot air has good fluidity, it greatly increases the heating area of the tobacco material, making it more evenly heated. Therefore, air-heating type smoking utensils have a good development prospect. However, the heat transfer of air-heating type smoking utensils mainly relies on the flow of air.
