Description
Technical Field
[0001] The present invention relates to the technical field of tobacco products, and in particular to a three-element dual-visible harm-reducing microsphere composite filter rod and a cigarette. Background Art
[0002] Currently, the cigarette industry is developing in a "harm reduction" and "health" direction, and consumers are increasingly concerned about the health risks of smoking. Traditional cellulose acetate cigarette filter rods use a filamentous structure within the filter rod to block harmful components such as tar and particulate matter from the smoke. While this can achieve a certain degree of smoke filtration and thus reduce harm, the filtration efficiency of these cigarette filter rods is limited. Furthermore, the simple smoke filtration provided by this structure is unable to cool and humidify the smoke produced by traditional burning tobacco. The smoke is dry and astringent upon entry, especially as the cigarette burns near the mouth, where the smoke temperature is higher, causing significant irritation to the smoker's mouth and significantly affecting the taste of the smoke.
[0003] It can be seen that the current cigarette filter rods cannot meet consumers' higher requirements for smoke filtration effect, smoking comfort and smoke taste, especially in the needs of harm reduction, humidity adjustment and improving smoking experience, the existing technology seems insufficient.
[0004] Therefore, how to design and provide a new type of composite filter rod to better reduce harmful substances in smoke, regulate smoke humidity, and be innovative in appearance and user experience has become a technical problem that needs to be urgently solved in the current field of tobacco product technology. Summary of the Invention
[0005] In response to the problems existing in the prior art, the present invention provides a three-element dual-visible harm-reducing microsphere composite filter rod and cigarette. By setting the filter rod as a multi-section composite structure, the smoke is filtered in multiple sections, and harm-reducing microspheres are arranged in the filter rod. The microspheres have a large number of micropores. The presence of the micropores increases the contact area between the microspheres and the smoke compared to the surface of the non-porous microspheres, causing the smoke to collide when passing through the microspheres, so that the harmful substances in the smoke are effectively intercepted and adsorbed on the microspheres to achieve efficient filtration of the smoke to reduce tar and harm; and the porous structure of the microspheres can carry water and other moisturizing molecules, help balance the humidity of the smoke, make the smoke entrance no longer dry, reduce irritation to the oral cavity, and enhance the smoking experience; in addition, the mouth section of the filter rod is set to a acetate filter rod with a special shape, which provides a comfortable smoking experience while also having a certain aesthetics.
[0006] The technical solutions of the present invention are as follows: In a first aspect of the present invention, a ternary dual-visible harm-reducing microsphere composite filter stick is provided, comprising: The first filter segment, the middle cavity segment and the second filter segment at the inlet end are arranged near the cigarette, and the outer sides of the first filter segment, the middle cavity segment and the second filter segment at the inlet end are covered with a plug-in paper; A first flue gas flow channel is provided inside the first filter segment along the flue gas flow direction; A spherical structure is provided in the cavity segment, and a surface of the spherical structure has a plurality of pore structures; A second flue gas flow passage is provided inside the second filter segment along the flue gas flow direction. In some embodiments of the present invention, both the first filter segment and the second filter segment are made of cellulose acetate material. In some embodiments of the present invention, the diameters of the first filter segment, the cavity segment in the middle, and the second filter segment at the inlet end are all consistent. In some embodiments of the present invention, the first flue gas flow channel is arranged at an axial position of the first filter segment along the flue gas flow direction, and a diameter of the first flue gas flow channel is smaller than a diameter of the first filter segment. In some embodiments of the present invention, the diameter of the spherical structure is smaller than the diameter of the cavity structure, and the diameter of the spherical structure is smaller than the spacing between the first filter segment and the second filter segment. In some embodiments of the present invention, the diameter of the spherical structure is greater than the diameter of the first flue gas flow channel, and the diameter of the spherical structure is greater than the diameter of the second flue gas flow channel. In some embodiments of the present invention, the second flue gas flow channel is arranged at an axial position of the second filter segment along the flue gas flow direction. In some embodiments of the present invention, the plug-wrapped paper is transparent plug-wrapped paper with no air permeability. In some embodiments of the present invention, the spherical structural members are configured as nano-scale porous composite silicon spheres, and moisturizing molecular materials are provided inside the plurality of porous structures. In a second aspect of the present invention, a cigarette is provided, comprising any one of the above-mentioned ternary dual-visible harm-reducing microsphere composite filter rods.
[0007] One or more technical solutions of the present invention have the following beneficial effects: The present invention provides a three-element dual-visible harm-reducing microsphere composite filter rod and cigarette. By configuring the filter rod as a multi-segment composite structure, the smoke is filtered in multiple stages, thereby improving the filtering effect, smoking comfort, and smoke taste of the smoke. The entire composite filter rod is provided with a first filter section near the cigarette, and a smoke flow channel is axially provided at the first filter section. The diameter of the smoke flow channel is smaller than the diameter of the filter rod. The cross-sectional area of the smoke flow channel is reduced, thereby compressing the smoke, playing a preliminary mixing role on the smoke and improving the taste. At the same time, since the flow rate of the smoke becomes faster after compression, the collision force between the smoke and the inner wall of the smoke flow channel can be increased, so that the tar and particulate matter in the smoke are better adsorbed on the inner wall of the smoke flow channel, further reducing the tar and harm of the smoke. The accelerated smoke enters the middle cavity and collides with the microspheres, further mixing the smoke. The microspheres have a large number of micropores on their surface. Compared to non-porous microspheres, the presence of micropores increases the contact area between the microspheres and the smoke, causing the smoke to collide with the microspheres as it passes through them. This effectively intercepts and adsorbs harmful substances in the smoke onto the microspheres, achieving efficient filtration of smoke to reduce tar and harm. Furthermore, the porous structure of the microspheres can carry water and other moisturizing molecules, helping to balance the humidity of the smoke, making the smoke no longer dry at the entrance, reducing oral irritation and enhancing the smoking experience. The mouth-side section is set as an acetate filter rod with a specially shaped smoke flow channel, which can reduce the smoke suction resistance, make the smoker inhale more smoothly, provide a comfortable smoking experience and also have a certain aesthetics.

DETAILED DESCRIPTION
[0009] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0010] Example 1 In a typical embodiment of the present invention, a three-component dual-visible harm-reducing microsphere composite filter stick is proposed, comprising: The first filter segment 2, the cavity segment in the middle and the second filter segment 4 at the inlet end are arranged near the cigarette, and the outer sides of the first filter segment 2, the cavity segment in the middle and the second filter segment 4 at the inlet end are covered with a plug-in paper 1; A first flue gas flow channel 5 is provided inside the first filter segment 2 along the flue gas flow direction; A spherical structure 3 is provided in the cavity segment, and the surface of the spherical structure 3 has a plurality of pore structures; A second flue gas flow channel 6 is provided inside the second filter segment 4 along the flue gas flow direction. Furthermore, the first filter segment 2 and the second filter segment 4 are both made of cellulose acetate material. Furthermore, the diameters of the first filter segment 2, the middle cavity segment and the second filter segment 4 at the inlet end are all consistent. This arrangement facilitates rolling and molding. Furthermore, the first flue gas flow channel 5 is arranged at the axial position of the first filter segment 2 along the flue gas flow direction, and the diameter of the first flue gas flow channel 5 is smaller than the diameter of the first filter segment 2 . Furthermore, the diameter of the spherical structure 3 is smaller than the diameter of the cavity structure, and the diameter of the spherical structure 3 is smaller than the distance between the first filter segment 2 and the second filter segment 4. This arrangement facilitates the movement of the spherical structure 3 in the cavity structure. Furthermore, the diameter of the spherical structure 3 is larger than the diameter of the first flue gas flow channel 5, and the diameter of the spherical structure 3 is larger than the diameter of the second flue gas flow channel 6. This arrangement can prevent the spherical structure 3 from falling into the first flue gas flow channel 5 or the second flue gas flow channel 6 and causing blockage.
[0011] Furthermore, the second flue gas flow channel 6 is arranged at the axial position of the second filter segment 4 along the flue gas flow direction. The shape of the second smoke flow channel 6 can be designed to be a special leaf-shaped shape and has a porous design. The second filter segment 4 not only provides a comfortable smoking experience, but also has a certain aesthetic appeal. Through this section of the filter rod, consumers can see the spherical structure 3 in the middle section, forming a unique visual effect.
[0012] Furthermore, the plug-wrapped paper 1 is a transparent plug-wrapped paper 1 without air permeability.
[0013] In this embodiment, the plugging paper 1 is transparent plugging paper 1 with no air permeability. On the one hand, it can ensure the sealing of the smoke when passing through the filter rod to prevent smoke leakage. On the other hand, the flow and mixing process of the smoke in the guide piece can be observed by the smoker through the transparent plugging paper 1, which increases the interest of smoking. Furthermore, the spherical structural member 3 is configured as a nano-scale porous composite silicon sphere, and a plurality of pore structures are provided with moisturizing molecular materials inside.
[0014] In this embodiment, the spherical structure 3 can be provided in a variety of colors and can be observed by the smoker through the transparent wrapping paper 1, thereby increasing the fun of smoking.
[0015] In a second aspect of the present invention, a cigarette is provided, comprising any one of the above-mentioned ternary dual-visible harm-reducing microsphere composite filter rods.
[0016] Example 2 The difference from Example 1 is that the shape of the second smoke flow duct 6 can be designed to be a special plum blossom shape and has a porous design. The second filter segment 4 not only provides a comfortable smoking experience, but also has a certain aesthetic appeal. Through this section of the filter rod, consumers can see the spherical structure 3 in the middle section, forming a unique visual effect.
[0017] The present invention provides a three-element dual-visible harm-reducing microsphere composite filter rod and cigarette. By configuring the filter rod as a multi-segment composite structure, the smoke is filtered in multiple stages, thereby improving the filtering effect, smoking comfort, and smoke taste of the smoke. The entire composite filter rod is provided with a first filter section near the cigarette, and a smoke flow channel is axially provided at the first filter section. The diameter of the smoke flow channel is smaller than the diameter of the filter rod. The cross-sectional area of the smoke flow channel is reduced, thereby compressing the smoke, playing a preliminary mixing role on the smoke and improving the taste. At the same time, since the flow rate of the smoke becomes faster after compression, the collision force between the smoke and the inner wall of the smoke flow channel can be increased, so that the tar and particulate matter in the smoke are better adsorbed on the inner wall of the smoke flow channel, further reducing the tar and harm of the smoke. The accelerated smoke enters the middle cavity and collides with the microspheres, further mixing the smoke. The microspheres have a large number of micropores on their surface. Compared to non-porous microspheres, the presence of micropores increases the contact area between the microspheres and the smoke, causing the smoke to collide with the microspheres as it passes through them. This effectively intercepts and adsorbs harmful substances in the smoke onto the microspheres, achieving efficient filtration of smoke to reduce tar and harm. Furthermore, the porous structure of the microspheres can carry water and other moisturizing molecules, helping to balance the humidity of the smoke, making the smoke no longer dry at the entrance, reducing oral irritation and enhancing the smoking experience. The mouth-near section is set as a acetate filter rod with a specially shaped smoke flow channel, which can reduce the smoke suction resistance, make the smoker inhale more smoothly, provide a comfortable smoking experience while also having a certain aesthetics. The end of the mouth-near section is set in a variety of shapes, which cooperate with the internal microspheres to realize the dual-visual design of the filter rod, thereby enhancing the aesthetics and fun of smoking.
[0018] Although the above describes the specific embodiments of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without any creative work are still within the scope of protection of the present invention.
