Definitions
- the invention relates to a cooling nozzle stick and a smoking product, belonging to the field of smoking products.
- the mainstream heating non-burning cigarettes on the market include Philip Morris' iQOS and British American Tobacco's glo.
- Philip Morris' iQOS When the two cigarettes reach the atomization temperature under the heating condition of 250-350°C, the high temperature atomizes the smoke
- the temperature that enters the mouth through the filter segment will be higher than the temperature at which ordinary cigarettes burn, resulting in excessive hotness of the inlet smoke.
- the existing technology mainly uses a phase change cooling material to cool the longitudinally flowing high-temperature flue gas.
- the material of the cooling section of iQOS is mainly pleated, pleated, aggregated and folded polylactic acid (PLA) sheets.
- PLA polylactic acid
- the phase change temperature-reducing material PLA sheet melts after contacting with high-temperature flue gas, which leads to blockage of the flue gas channel, affecting the material's temperature-reducing effect and even leading to a significant reduction in smoke.
- one of the objects of the present invention is to provide a cooling nozzle stick to significantly reduce the temperature of the high-temperature flue gas inlet and improve the smoking experience; the second object of the present invention is to provide a smoking article.
