Background technique

Compared with traditional cigarettes, heat-not-burn cigarette products have been widely recognized by governments and consumers in recent years because of their low harm, no second-hand smoke smell, and environmental friendliness. At present, the heating non-combustion cartridges sold on the market are mainly composed of a smoke material section, a cooling section, a filter section, etc., and are manufactured by using special composite manufacturing equipment and production processing technology; therefore, their cost is high, and the price is high. There are also few purchase channels.

Most of the existing heat-not-burn cartridge smoke materials are shredded tobacco that is crushed and broken into a pulp, and hemp pulp, wood pulp, etc. are added to form a reconstituted tobacco leaf shape, resulting in a baked paper flavor when smoking. The material liquid pre-added in the cartridge is easy to oxidize, volatilize, and bleed out during long-term storage, causing quality problems.

There are also manufacturers who use traditional cigarettes as heat-not-burn cartridges and insert them into heat-not-burn appliances, and use the temperature of 300-350℃ for heating and smoking, but the sensory quality is difficult to be accepted by consumers, and the smoke nicotine produced It will greatly exceed the smoking standard, and it will also produce nausea, dizziness and other physical discomforts caused by high nicotine intake.
