TECHNICAL FIELD

[0001] The utility model belongs to the technical field of cigarette filter stick, specifically relates to a special-shaped composite filter stick. BACKGROUND

[0002] The filter stick is an important component of cigarettes, which can effectively filter and intercept harmful components in smoke. With the increasing diversification of consumer demand for cigarette products and growing health concerns, as well as the demand for filter stick function enhancement (such as reducing tar, reducing harm, enhancing flavor, and keeping moisture) in the industry, special filter sticks have emerged. In order to make cigarette filter sticks show a diversified trend and meet the needs of different consumers, while achieving better anti-counterfeiting effect, the cigarette industry has developed a variety of novel and unique special-shaped filter sticks. These different forms of characteristic filter stick products have an attractive appearance and high recognition, and have gradually become popular in the cigarette industry.

[0003] Chinese patent CN216874983U discloses a filter stick for cigarettes and a cigarette, belonging to the technical field of cigarette filter sticks.
