Description
[ technical field ] A method for producing a semiconductor device
The invention belongs to the technical field of tobacco materials. More specifically, the present invention relates to a flavor-producing material for heated non-burning cigarettes, and also relates to a method for producing the flavor-producing material for heated non-burning cigarettes.
[ background of the invention ]
Unlike conventional cigarettes, heated non-burning cigarettes are smoked by heating a non-burning cartridge with electronic equipment, allowing consumers to smoke the tobacco flavor while reducing harmful smoke constituents resulting from combustion and thermal cracking in conventional cigarettes.
The heating non-combustion cigarette smoking product mainly comprises an aerosol generating device, an aerosol cooling device and an aerosol filtering device; the heating element inside the aerosol generating device heats the aerosol generating substrate to generate aerosol, the aerosol is cooled by the heat transfer of the aerosol cooling device to reduce the temperature of the aerosol, and the aerosol is filtered by the aerosol filtering device. The aerosol generating device is composed of a heating element and a fragrance producing base body, and the fragrance producing base body is composed of a fragrance producing material. In a heating non-combustion cigarette system, when the aroma-producing material used in the prior art is heated by a heating element, the heat transfer is not uniform, so that the smoking quantity is often insufficient, the smoking quality is not high, and the smoking feeling of a consumer is further influenced; meanwhile, the aroma-producing material is not effectively utilized due to the non-uniformity of heat transfer; therefore, the present inventors have conducted intensive studies on a fragrance-producing material, and have finally completed the present invention.
