Description

Technical Field

[0001] The utility model relates to the technical field of cigarettes, in particular to a silica gel spiral groove filter rod. Background Art

[0002] Cigarette filters filter smoke and are a crucial component of cigarettes. They remove the majority of tar from smoke, reducing smokers' intake and minimizing its harmful effects. Spiral channels effectively increase the length of the smoke flow path, increasing the contact time between smoke and the filter material and enhancing the tar reduction and harm reduction effects. Existing spiral channels typically use grooved paper, with shallow grooves located on the periphery of the filter material. This has limited impact on airflow and ineffective tar reduction and harm reduction. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a silica gel spiral groove filter rod with good tar reduction and harm reduction effects.

[0004] The technical solution of the utility model is: a silicone spiral groove filter rod, including a wrapping layer and a filter element, the filter element is provided with a spiral shaft core made of silicone material along the axis, the spiral shaft core is composed of at least three septa arranged in a star shape in the radial direction, the septa are spirally wound around the axis, so that the filter element forms a plurality of smoke channels composed of spiral grooves along the axial direction.

[0005] The technical effects of this utility model are as follows: the core portion serving as a separator is made of silicone, with deep grooves and smooth, continuous spiral channel walls. This significantly separates the flue gas, significantly reducing tar and harm, while also significantly cooling the flue gas. The use of silicone significantly reduces the difficulty of machining the spiral shaft core, resulting in smooth, thinner partitions and less space. This filter can be combined with one or more functional filter rods, such as acetate filter rods, grooved filter rods, flavored filter rods, threaded filter rods, and capsule filter rods, to form a binary or multi-component composite filter rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] Figure 2 It is a schematic diagram of the cross-sectional structure of the present utility model. DETAILED DESCRIPTION

[0008] like Figure 1 and 2 As shown, a silicone spiral groove filter rod includes a wrapping layer 1 and a filter element 2. The filter element 2 is provided with a spiral shaft core 3 made of silicone material along the axis. The spiral shaft core 3 is composed of at least three partitions 4 arranged in a star shape in the radial direction. The partitions 4 are spirally wound around the axis, so that the filter element 2 forms a plurality of smoke channels composed of spiral grooves 5 along the axial direction.

[0009] The number of the septa 4 of the spiral core 3 is 3 to 6.

[0010] The spiral core 3 has four septa 4 .

[0011] The wrapping layer 1 is made of forming paper.

[0012] The filter element 2 is made of cellulose diacid tow.

[0013] The filter rods can be manufactured with circumferences ranging from 19 to 24 mm and lengths from 84 to 144 mm. During production, the spiral core is introduced into the filter element through a hollow circular tube. After exiting the tube, the filter element and the spiral core naturally combine.
