Title:
SMOKELESS CIGARETTE HAVING DECREASED VAPOR TEMPERATURE AND PREVENTING HEAT-CAUSED COLLAPSE OF CIGARETTE HOLDER
Document Type and Number:
WIPO Patent Application WO/2018/214953
Kind Code:
A1
Abstract:
A smokeless cigarette having a decreased vapor temperature and preventing the heat-caused collapse of a cigarette holder comprises a filter tip, a heat-resistant hollow section and a tobacco section sequentially connected, wherein the heat-resistant hollow section consists of a heat-resistant hollow section cover and a heat-resistant hollow section hollow layer. The heat-resistant hollow section is made by rolling a high-temperature resistant material into a hollow tubular structure; the high-temperature resistant material forms the heat-resistant hollow section cover. The heat-resistant hollow section hollow layer is a cavity structure formed and surrounded by the heat-resistant hollow section cover. An inner layer of the heat-resistant hollow section cover is coated with a layer of phase-change heat-absorbing material, or the heat-resistant hollow section hollow layer is filled with a phase-change heat-absorbing material. The smokeless cigarette of the present invention can achieve a better fit with a peripheral heater, is adapted to an inner core heater, and will not result in the heat-caused collapse of a cigarette holder contacting tobacco shreds due to heat conducted by a cover when the periphery is heated.
