The research on new tobacco products and their heating devices has therefore become an important task in the tobacco industry, where the research on tobacco materials is of great importance.
However, when a consumer smokes low-temperature cigarette sheets, no matter the periphery or the inner core is heated, compared with the traditional cigarette burning and smoking, the problems of insufficient physiological satisfaction and insufficient smoke amount exist. This is because, on the one hand, the low temperature cigarette tobacco segment, which typically comprises about 0.3 grams (about 0.7 grams for a conventional cigarette), contains limited amounts of tobacco flavor components, the atomizing medium loaded, and the added flavor; on the other hand, when an external heat source is used for heating, the heat conductivity of the tobacco substance is poor, the temperature of the tobacco substance close to the heat source is high, the atomization medium, the flavor component and the external flavoring contained in the tobacco substance can be well atomized and volatilized, the temperature of the tobacco substance far away from the heat source is low, and the atomization medium, the flavor component and the external flavoring contained in the tobacco substance cannot be effectively atomized and volatilized.
The patent document with the application number of CN201810585356.4 discloses a low-temperature cigarette containing metal wires and a preparation method thereof, wherein the low-temperature cigarette comprises the following components in percentage by mass: 60-95% of tobacco substances and 5-40% of metal wires, wherein the tobacco substances are one or two of tobacco sheet wires and tobacco leaf wires, the tobacco substances contain an atomizing agent and tobacco essence and flavor, and the tobacco substances and the metal wires are uniformly mixed and then are subjected to cigarette making by adopting a traditional cigarette making method to prepare the low-temperature cigarette. In this application, the addition of wires to the foil improves the thermal conductivity and uniformity of thermal conductivity. However, since the low temperature cigarette requires heating, the wire is also heated, and if the wire used contains impurities, there is a problem that an offensive odor may be generated during smoking, and if the wire having a high purity is used, there is a problem that the cost is high. And the application cannot solve the problem of insufficient atomization amount.
The patent with the application number of CN201911118564.4 discloses a preparation method of a special sheet for heating cigarettes. Which comprises the following steps: crushing tobacco leaves into tobacco powder; uniformly mixing the tobacco powder, the inorganic inert heat conduction material, water, the atomizing agent, the sizing material, the external fiber and the dispersing agent, and then pressing the mixture to form a substrate; drying and shredding the substrate to obtain the special slice for heating cigarettes. Although the patent is effective for improving the uniformity of heat conduction and the strength of the sheet, the problem that the content of the tobacco flavor components is insufficient and the amount of the added fibers is too much, which causes the increase of miscellaneous gas, still cannot be solved.
