Description

TECHNICAL FIELD

[0001] The utility model relates to cigarette filter tip technical field, concretely is the cigarette external filter device with rotation friction aroma releasing function. BACKGROUND

[0002] The filter tip is the important bridge of cigarette aroma to reach the oral cavity of the smoker, and plays an important role in the regulation of cigarette aroma. In recent years, the external filter tip is more and more favored by consumers. The external filter tip is independent of the cigarette structure, and is separately manufactured and formed. When smoking, it can be flexibly assembled and spliced to the cigarette according to the personal preference of the consumer, thereby playing the role of aroma compensation of the cigarette and embodying the characteristic function. The types of external filter tips on the market include particles, burst beads, etc. The particle material has a slow-release aroma enhancement effect, but the aroma is obviously weakened in the later stage of smoking. The burst bead releases aroma components after being pinched, but the release times are limited and it cannot be used repeatedly.

[0003] The friction aroma releasing technology is to embed the essence to form micron-sized microcapsules, and to make the microcapsules deform by external pressure to release aroma. For example, the patent with the title of rotating friction aroma releasing tipping paper, publication number CN209073536U, is provided with a microcapsule coating on the glue area of the tipping paper. The microcapsule coating is wrapped with microcapsules containing natural plant essence. By rotating the filter rod or the glue area of the tipping paper, the breaking line on the tipping paper is broken, and the microcapsule coating of the glue area is rubbed with the formed paper in rotation to achieve the purpose of rapidly releasing aroma. The patent with the title of preparation process of cigarette tipping paper with friction aroma releasing effect, publication number CN117738030A, uniformly prints the water-based essence microcapsule emulsion on the surface of the tipping paper by gravure to form a water-based essence microcapsule emulsion layer. In the smoking process, when the fingers pinch the cigarette, the microcapsules are squeezed and rubbed to release aroma, thereby improving the problem of aroma loss of the existing cigarette.

[0004] The smoke during cigarette smoking mainly flows through the central axis area of the filter rod, and the aroma components loaded in the filter rod are brought into the mainstream smoke by smoke elution to increase the aroma of the cigarette. However, the aroma components of the friction microcapsules in the above-mentioned patents are only added between the tipping paper and the formed paper, and cannot be added inside the filter tip. The aroma components released during smoking are not easy to be brought into the smoke, have little effect on the quality of cigarette smoking, and the tipping paper is relatively soft and is easy to wrinkle the surface of the cigarette when twisted.
