Description

Technical Field

[0001] The utility model relates to the technical field of cigarettes, in particular to a mixed filter rod with a step-by-step aroma-releasing particle component. Background Art

[0002] In the tobacco industry, cigarette flavoring technology is developing rapidly, including cigarette popping beads, microcapsules, nanoparticles, powdered particles, etc.; however, a single cigarette additive cannot reasonably combine the flavoring and moisturizing properties of cigarettes to achieve the best results for both.

[0003] Based on this, more research directions have turned to setting particles with flavoring and moisturizing effects in cigarette filter rods. Since flavoring materials and moisturizing materials cannot be well integrated, some technical solutions use two or more different particles in the filter rod to seek to obtain the superposition effect of flavoring and moisturizing. For example, "202022272014.2 A granular heat-not-burn tobacco product" includes a tobacco paper tube, in which a particle segment and a filter segment are arranged, and the particle segment includes a first particle segment, a second particle segment and a third particle segment; "202320273536.5 A composite granular heating cigarette containing bursting beads" is composed of a connected first composite filter rod segment and a filter segment, the first composite filter rod segment includes a smoke-releasing particle segment and a barrier segment, and the filter segment contains at least one bursting bead filter rod; the barrier segment of the first composite filter rod segment is close to the filter segment, and the filter segment is located at the lip end.

[0004] However, there are obvious problems with the above technical solution. First, whether different particles will affect each other when releasing effective ingredients, resulting in neither effect being obvious; second, even if the above problems are not considered, with regard to the above solution, simply adding several different particles to a cigarette filter rod with a very small volume will inevitably reduce the amount of the original wire bundle used for adsorption and filtration, causing the most original and basic function of the filter rod to be lost, and will also greatly increase the smoking resistance of the cigarette, resulting in the inability to use it normally. Summary of the invention

[0005] In order to solve the above problems, the utility model discloses a hybrid filter stick with a step-by-step fragrance-releasing particle component.

[0006] The utility model adopts the following technical scheme: a hybrid filter rod with a step-by-step flavor-releasing particle component, which adopts a structure formed by connecting multiple independent functional sections through a wrapping layer, and is characterized in that, starting from the cigarette section, it includes a starting section 1, a moisturizing functional section 2, a transition section 3, a flavoring functional section 4 and a mouth section 5 in sequence; each structural section is connected in sequence, and a molding paper layer and a tipping paper layer are wrapped around the periphery, and the starting section 1, the transition section 3 and the mouth section 5 are all a tow structure as a whole; a tow layer is also arranged between the moisture-retaining functional section 2 and the flavoring functional section 4 and the molding paper layer.

[0007] The moisturizing functional section 2 is a cylinder with upper and lower openings, with a length of 1 / 4 of the entire length of the filter rod and a width of 1 / 2-2 / 3 of the width of the longitudinal section of the filter rod; it is arranged at the axial position of the filter rod, and the interior of the cylinder is evenly distributed with liquid controllable micro-pills 6 as the content; the cylindrical outer layer of the moisturizing functional section 2 is a non-woven fabric layer 7 coated with plasticizer both inside and outside and solidified; a smoke guide tube 8 is evenly distributed on the entire outer wall of the moisturizing functional section 2, that is, the non-woven fabric layer 7, and the smoke guide tube 8 extends from the inner wall of the non-woven fabric to the outside. In addition, the axial extension line of the smoke guide tube 8 intersects with the vertical axis of the filter rod, and there is an angle between the two; and a non-woven fabric sealing layer with air holes is arranged at the upper and lower openings of the moisturizing functional section 2, and the aperture of the air holes is smaller than the diameter of the controllable micro-pill 6.

[0008] The aroma enhancement functional section 4 and the moisture retention functional section 2 are coaxially arranged with the transition section 3 as an interval, and are funnel-shaped as a whole, with a length of 1 / 4 of the entire filter rod, a width of the upper bottom edge of 1 / 3 of the width of the longitudinal section of the filter rod, and a width of the lower bottom edge of 2 / 3 of the width of the longitudinal section of the filter rod; a cylindrical port is arranged on the side close to the transition section 3, and the angle between the inner side of the hypotenuse of the funnel and the horizontal line is 45-60°, and solid aroma-releasing particles 11 are evenly distributed inside the funnel; the outer layer of the aroma enhancement functional section 4 is a non-woven fabric layer 7 which is coated with plasticizer inside and outside and solidified, and air guide holes 9 with the axis in the vertical direction are evenly distributed on the non-woven fabric layer 7, and the aperture of the air guide holes 9 is smaller than the diameter of the solid aroma-releasing particles 11; a non-woven fabric sealing layer with air holes is arranged at the upper and lower end ports of the aroma enhancement functional section 4, and the aperture of the air holes is smaller than the diameter of the solid aroma-releasing particles 11.

[0009] Preferably, the diameter of the controllable micro-pellets 6 is 1.0-1.5 mm, and the diameter of the solid fragrance-releasing particles 11 is 1.0-2.5 mm.

[0010] Preferably, the smoke guide tube 8 extends to be flush with the outer wall and then continues to extend 2-3 mm along its axial direction, and the port is wrapped by the tow layer between the flavor enhancement functional section 4 and the forming paper layer.

[0011] The smoke guide tube 8 has a uniform inner diameter, which is smaller than the diameter of the controllable pellets 6 and is 0.5-0.8 mm.

[0012] There is an angle of 30-45° between the axis extension line of the smoke guide tube 8 and the vertical axis of the filter rod.

[0013] In order to prevent the controllable micro-pills 6 from blocking the inlet end of the flue gas guide tube 8 arranged inside the moisture preservation functional section 2, a concave-convex structure 10 surrounding the entire port is arranged at the inner inlet end of the flue gas guide tube 8. This concave-convex structure 10 can be achieved by setting a corresponding concave-convex structure 10 at the root of the molding mold when the flue gas backflow pipe is molded by the molding mold.

[0014] Preferably, suction resistance adjusting micropores are arranged on the tipping paper layer and the shaping paper layer on the periphery of the starting section 1, and air-replenishing micropores penetrating the tipping paper layer, the shaping paper layer and the internal tow structure are arranged in the cylindrical port area of ​​the flavor enhancing functional section 4, and the depth of the air-replenishing micropores extends to the air guide holes 9 arranged on the corresponding cylindrical port.

[0015] When designing the filter rod described in the present application, the distribution of smoke flow in a conventional filter rod is fully considered. Usually, the smoke passing through the area close to the axis of the filter rod, which accounts for 30% of the cross-sectional area, accounts for more than 60% of the total smoke. Therefore, a cylindrical component is used to accommodate the controllable micro-pellets 6, and it is set at the center of the filter rod so that most of the smoke can flow through the cylindrical component; at the same time, according to the characteristics of the controllable micro-pellets 6 as moisturizing additives that break the wall and release after being heated, the moisturizing functional section 2 is set at a position close to the cigarette section to ensure that the smoke flowing through the functional section The smoke has a sufficient temperature to cause the outer wall of the controllable micro-pill 6 to break to release the moisturizing substance; after the moisturizing substance is mixed in the smoke, in order to avoid the smoke from concentrating on the axial center and increasing the suction resistance, a smoke guide tube 8 with a specific angle is set on the cylindrical outer layer of the moisturizing functional section 2 to guide part of the smoke to the outer ring of the filter rod, and the rest of the smoke is still broken through the remaining controllable micro-pills 6 through the cylindrical component to ensure that the smoke is evenly distributed in the filter rod, and cooperate with the suction resistance adjustment micropores set on the periphery of the starting section 1 to balance the filter tip suction resistance and improve the smoking taste.

[0016] As for the flavoring functional section 4 arranged far away from the cigarette section, it is based on that the release conditions of the flavor substances of the solid flavor-releasing particles 11 are relatively loose, and the flow of smoke with relatively low temperature can prompt them to release flavor substances, and considering that the smoke temperature drops more gradually compared with the moisturizing functional section 2 far away from the cigarette section, the flavoring functional section 4 is arranged to be a funnel shape from small to large, with high smoke temperature at the front end, and a high degree of release of the solid flavor-releasing particles 11, and relatively few particles can meet the release requirements. Therefore, the size of the flavoring functional section 4 here is relatively small. As the distance increases, the smoke temperature decreases faster and lower, and the release degree of the solid flavor-releasing particles 11 is relatively low, and more particles are needed to meet the release requirements. Therefore, the size of the flavoring functional section 4 here is relatively large.

[0017] The present application adopts the above-mentioned structural design, which not only takes into account the release conditions of the moisturizing material and the flavoring material, but also performs smoke guide settings according to the distribution ratio of the smoke flow in the filter rod, ensuring that the smoke flows as evenly as possible in the filter rod, and also specially sets suction resistance adjustment holes and air supply holes to comprehensively optimize and adjust the suction resistance of the filter rod.
