Definitions

  • the invention belongs to the technical field of tobacco and relates to smoke treatment, in particular to products for reducing the temperature of cigarette smoke.
  • Heat-not-Burn cigarette is a new type of tobacco product which uses special heat source to heat cut tobacco (below 400 °C or even lower) without burning, which can significantly reduce the release of harmful components in smoke.
  • the smoke temperature is high in Heat-not-Burn cigarette, which brings smoke stimulation and burning sensation, and reduces the suction comfort of cigarettes.
