Description

A composite mouthpiece capable of adjusting the moisture content of heat-not-burn cigarettes

technical field

The invention belongs to the technical field of heat-not-burn cigarette tobacco, and particularly relates to a composite tip rod capable of adjusting the moisture content of heat-not-burn cigarettes.

Background technique

At present, from the perspective of the development trend of international heat-not-burn cigarettes, foreign tobacco companies have launched several different products, and heat-not-burn cigarettes have entered a new period of development. The heating temperature of heat-not-burn cigarettes is generally lower than 500°C. Within this range, the higher the temperature, the greater the release of harmful substances. Therefore, the function of the filter rod is mainly to cool down and filter. In the products produced and marketed by various companies at this stage, the design of the filter rod has not added other functions, such as the targeted balance of the moisture content of the smoking section to improve the suction effect. Because the smoking material of heat-not-burn cigarettes is made of tobacco sheets, it is more sensitive to the environment than traditional tobacco materials, and it is easy to absorb moisture rapidly after being placed for a long time. Insufficient, the smoke volume and aroma are weakened, which seriously affects the sensory quality of smoking. However, the traditional heat-not-burn cigarette filter rod design does not take this factor into consideration, and the characteristics and structural positions of the traditional cooling elements do not have the function of balancing the moisture of the smoking material. Known heat-not-burn filter rods use tobacco material as a cooling element, but their overall construction risks drawing tobacco particles directly into the oral cavity.

Therefore, in view of the above problems, the present invention proposes a novel composite filter rod.
