Smoking cartridge of gas heating smoking article and its smoking article

Abstract

A smoking cartridge of a gas-heated smoking article and its smoking articles are provided. The smoking cartridge includes a heat-not-burn smoking body and a mouth piece. The heat-not-burn smoking body is a column made of thermal conductive metal foil, wrapping tobacco and smoking liquid capsules. In a heating process of the heat-not-burn smoking body, the smoking liquid capsules release a smoking liquid and increase a vapor volume. A low-temperature cigarette is provided with an energy of burning propane gas or butane gas to smokers who are having difficulties to quit smoking, wherein the low-temperature cigarette produces a similar smoke with a taste of ordinary cigarettes. Since the heat-not-burn smoking body do not burn, the heat-not-burn smoking body reduces a variety of harmful components produced by the ordinary cigarettes due to tobacco combustion and thermal cracking, such as tar, carbon monoxide, cigarette ash and other harmful substances with traditional cigarette's combustion.
