Smokeless cigarette having decreased vapor temperature and preventing heat-caused collapse of cigarette holder
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.
