Definitions

  • the present invention relates to the field of novel cigarette smoking utensil, and in particular, to a smoke generating device with induction heating at the front end of the cigarette.
  • heat-not-burn cigarettes are gaining increasing popularity among smokers since they are less harmful than traditional burning cigarettes.
  • heating methods of heat-not-burn cigarettes include: contact electric heating, non-contact electric heating, charcoal heating, etc.
  • Contact electric heating refers to obtaining flue gas through direct contact heating of cigarettes, which uses electric heating pipes, needles or plates and other forms of heating devices to directly contact cigarettes or tobacco shreds, with direct contact and baking of cigarettes or tobacco at a temperature lower than the ignition point of the cigarette, so that the aroma and smoking components of the tobacco shreds are volatilized, to meet smoking requirements of smokers.
  • the existing charcoal-heated cigarettes are ignited by a carbon rod attached to the front end of the tobacco, so that the air flowing through the carbon rod is rapidly heated.
  • tobacco shreds are baked and heated to achieve non-combustion heating.
  • tobacco aroma can be obtained, while harmful substances such as tar and nicotine produced in large quantities due to ignition can be avoided through such heating method.
  • charcoal-heated cigarette has the characteristics of less harm than the existing ordinary cigarettes, as the front end of the cigarette is attached with a carbon rod, which increases the difficulty of cigarette manufacturing, thereby affecting production efficiency; there are also weaknesses, i.e., it takes a long time for consumers to ignite the carbon rod, and the carbon rod may have a certain peculiar smell in case of burning. Besides, the carbon rod is difficult to control after igniting, tobacco shreds are still burning when not smoking, and the end of the carbon rod is in direct contact with or relatively close to the tobacco; thus, at the end of the burning carbon rod, there may be direct baking or critical baking of a small amount of residual tobacco shreds.
  • the existing non-contact electric heating method uses a smoking utensil that electrically heats the input air, a ring-shaped metal heater, a flat-layer metal heater, or a combined flat-layer metal heater is directly energized and heated, the air flowing through the surface is heated, which is introduced into the cigarette for omnidirectional heating.
  • non-contact heating is carried out using an air heating cartridge, but only the air flowing through the surface layer of the heating element can be sufficiently heated. This design therefore suffers from uneven heating of the air, which can lead to inconsistent smoking sensations in the smoke.
