Description

Technical Field

[0001] This invention belongs to the field of cigarette technology, specifically relating to a cigarette with a silicone rod at the end that can produce aroma through friction, and its preparation and usage methods. Background Technology

[0002] The flavor of existing cigarettes is mainly adjusted in two ways: one is to pre-add flavoring to the tobacco segment or filter. This method has the drawbacks that the flavoring is prone to volatilization during storage and the amount of flavoring released is uncontrollable. In addition, users cannot adjust the flavor concentration according to their own preferences. The other method is to set flavor capsules, such as flavor capsules, in the filter. The flavoring is released by breaking the flavor capsule. However, the flavor is released all at once after the flavor capsule breaks, which cannot achieve "on-demand flavoring". Moreover, the addition of flavor capsules requires additional production steps, which increases the complexity of the cigarette structure and the production cost.

[0003] This application is made to address the problem of uncontrollable fragrance release in existing technologies. Summary of the Invention

[0004] In this application, "proximal lip segment" refers to the segment of the cigarette that is close to the user's lips when in use, and "distal lip segment" refers to the segment that is close to tobacco segment 1.

[0005] When a cigarette is smoked, the direction of the smoke flow inside the cigarette is recorded as from upstream to downstream.

[0006] The "fragrance production by friction" in this application refers to the process of instantly releasing fragrance by breaking the outer shell of fragrance particles through mechanical friction and / or by accelerating the volatilization of fragrance through frictional heat.

[0007] This application provides a cigarette with a silicone rod at the end that can produce aroma by friction. The cigarette includes a tobacco section 1, a filter section 5 and a coaxial rod 2 arranged from upstream to downstream. The coaxial rod 2 includes a silicone rod 2-1 and a fiber bundle tube 2-2 arranged from the inside to the outside.

[0008] The fiber bundle tube 2-2 includes a near-lip fiber bundle tube 2-2-1 and a far-lip fiber bundle tube 2-2-2;

[0009] The outer wall of the silicone rod 2-1 is provided with a friction fragrance-producing layer 4, so that when the near-lip section fiber bundle tube 2-2-1 is rotated, the friction fragrance-producing layer 4 can produce fragrance due to the friction of the fiber bundle tube 2-2.

[0010] Preferably, the cigarette further includes: a first outer wrapping component 2-3;

[0011] The first outer packaging 2-3 includes a proximal lip forming paper covering the proximal lip fiber bundle tube 2-2-1 and a distal lip forming paper covering the distal lip fiber bundle tube 2-2-2;

[0012] An adhesive layer is provided between the first outer wrapping 2-3 and the fiber bundle tube 2-2, so that when the distal lip section forming paper is rotated, the fiber bundle tube 2-2 rotates while the silicone rod 2-1 does not rotate.

[0013] Preferably, the tobacco segment 1, the filter segment 5, and the coaxial rod 2 are all wrapped with a second outer wrapping member 3. The second outer wrapping member 3 has a weak connecting line 3-1. In the axial direction, the weak connecting line 3-1 is located between the near-lip segment forming paper and the far-lip segment forming paper, and coincides with the boundary line between the near-lip segment forming paper and the far-lip segment forming paper. At this time, the outer periphery of the coaxial rod 2 is wrapped with a first outer wrapping member 2-3.

[0014] An adhesive layer is provided between the second outer wrapping 3 and the first outer wrapping 2-3.

[0015] Preferably, the adhesive layer is a widened adhesive line.

[0016] The weak connection line 3-1 is formed by pre-drilling holes in the second outer packaging 3, so that the two sides of the weak connection line 3-1 are connected in a dotted manner similar to a stamp connection. The two sides of the weak connection line 3-1 are neither completely broken nor easily twisted / torn.

[0017] Preferably, the silicone rod 2-1 is a solid rod, a hollow rod, or a porous rod;

[0018] When the rod is hollow or porous, an airflow channel for flue gas circulation is formed inside the silicone rod 2-1. Preferably, the inner wall of the hollow or porous rod is loaded with auxiliary fragrance such as menthol, which helps to release fragrance under the action of flue gas heating, forming a "main fragrance + auxiliary fragrance" fragrance combination with the main fragrance generated by the friction fragrance layer 4.

[0019] Preferably, the outer wall of the silicone rod 2-1 is provided with axial grooves spaced apart in the circumference. When the fiber bundle tube 2-2 is rotated, the axial grooves form an airflow channel so that the aroma generated by the friction fragrance layer 4 can flow out along the airflow channel.

[0020] In one scenario, the outer wall of the silicone rod 2-1 has axially spaced grooves. During the molding of the fiber bundle tube 2-2, fiber bundle protrusions are formed that are slightly embedded in the axial grooves. When the fiber bundle tube 2-2 is rotated, the fiber bundle protrusions move out of the axial grooves, or the connection between the fiber bundle protrusions and the axial grooves becomes less tight. This creates a new airflow channel in the axial groove portion, allowing the aroma and smoke generated by friction to mix fully, thus improving the delivery efficiency of aroma and smoke.

[0021] The shape of the axial groove on the outer wall of the silicone rod 2-1 can be regular or irregular, for example, the outer periphery of the silicone rod 2-1 can be gear-shaped or petal-shaped.

[0022] Filter section 5 is a solid cellulose acetate bundle.

[0023] A second aspect of this application provides a method for preparing a cigarette according to any one of the first aspects, the method comprising the following steps:

[0024] 1. By dipping in a friction-generating liquid, at least the outer wall of the silicone rod 2-1 is loaded with a friction-generating layer 4;

[0025] 2. Wrap silicone rod 2-1 with fiber bundles and shape it to obtain silicone rod 2-1 wrapped with fiber bundle tube 2-2;

[0026] 3. After coating the outer periphery of the silicone rod 2-1 wrapped by the fiber bundle tube 2-2 with an adhesive layer, wrap the first outer wrapping part 2-3 to obtain a preliminary coaxial rod;

[0027] 4. The initial coaxial rod is circumferentially cut from the middle of the first outer wrapping 2-3 to the fiber bundle tube 2-2 without cutting the silicone rod 2-1. The fiber bundle tube 2-2 is cut into a near-lip fiber bundle tube 2-2-1 and a far-lip fiber bundle tube 2-2-2.

[0028] 5. After coating the outer periphery of the preliminary coaxial rod after ring cutting in step 4 with an adhesive layer, roll it together with filter section 5 and tobacco section 1 with pre-perforated tipping paper to form a cigarette.

[0029] The pre-perforated tipping paper has a pre-perforated weak connecting line 3-1. When rolling, the weak connecting line 3-1 covers the circumferential cut position of the initial coaxial rod, so that the weak connecting line 3-1 can be broken by rotating the near-lip section fiber bundle tube 2-2-1 of the cigarette, and the near-lip section fiber bundle tube 2-2-1 and the far-lip section forming paper and tipping paper wrapped around it will rotate accordingly.

[0030] The term "circumferential cut from the middle of the first outer wrapper 2-3" refers to the approximate middle position on the forming paper layer 2-3, not precisely the middle; it could also be a position slightly upstream or downstream.

[0031] Preferably, the circumferential cut position is 8-16 mm from the downstream end of the initial coaxial rod to ensure a sufficiently large rotation area. At this time, the weak connecting line 3-1 is also 8-16 mm from the downstream end of the initial coaxial rod.

[0032] Of course, if the silicone rod 2-1 is a hollow rod or a porous rod, a fragrance layer can also be loaded on its inner wall or porous structure during the dip coating process.

[0033] Preferably, the friction-generating fragrance liquid comprises: a binder and fragrance particles. Preferably, the friction-generating fragrance liquid further comprises a smoke-generating agent and a solvent.

[0034] Preferably, the spice particles have a shell that can be broken by friction. For example, the shell is made of a gelatin-gum arabic composite coagulated film. The gelatin and gum arabic solutions form an electrostatic composite film through pH adjustment. The film layer has high toughness and requires a large frictional force, such as kneading, to trigger its breakage.

[0035] The third aspect of this application provides a method of using the cigarette described in the first aspect, the method comprising: rotating the near-lip segment fiber bundle tube 2-2-1, and holding the far-lip segment fiber bundle tube 2-2-2 so that the far-lip segment fiber bundle tube 2-2-2 and the silicone rod 2-1 do not rotate;

[0036] Then the distal lip segment fiber bundle tube 2-2-2 and the friction fragrance-producing layer 4 rub against each other, causing the friction fragrance-producing layer 4 to produce fragrance.

[0037] Preferably, the aroma-producing layer 4 produces fragrance due to frictional heat, and / or the fragrance particles within the aroma-producing layer 4 are broken due to friction, thus producing fragrance.

[0038] For example, the outer shell of the fragrance particles in the friction-generating fragrance layer 4 may crack due to friction, causing the fragrance in the core of the fragrance particles to be released.

[0039] Preferably, after the cigarette is lit, the near-lip fiber bundle tube 2-2-1 is rotated several times before and / or during the intervals of inhalation.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] 1. This application provides a rotatable cigarette that produces aroma through friction. By setting a coaxial rod, when the distal lip fiber bundle tube 2-2-2 is rotated, the distal lip fiber bundle tube 2-2-2 and the friction aroma-producing layer 4 rub against each other, causing the friction aroma-producing layer 4 to produce aroma.

[0042] The aroma-generating process of the friction-generating aroma layer 4 is based on the synergistic effect of "physical rupture + frictional heat generation", as follows:

[0043] (1) Fragrance release dominated by physical rupture: When the fiber bundle tube 2-2 rotates relative to the friction fragrance-producing layer 4, mechanical friction is generated between them. This friction acts on the fragrance particles (with or without a shell) in the friction fragrance-producing layer, causing the fragrance particles or their shells to rupture and release the internal fragrance core material. The rupture rate of the fragrance particles increases with rotation time. The internal fragrance core material can be selected from natural extracts such as Chinese medicine, flowers, and fruits, including Panax notoginseng extract, tobacco extract, osmanthus extract, clove extract, plum extract, peppermint extract, and orange oil.

[0044] (2) Friction heat generation assists aroma volatilization: During the relative friction process, mechanical energy is converted into heat energy, which raises the temperature of the friction contact surface. This can reduce the volatilization threshold of the fragrance core material, accelerate the volatilization rate of liquid / semi-solid fragrance, and ensure that the aroma can quickly enter the user's mouth with the smoke.

[0045] (3) Controllability Guarantee: The amount of binder (carrageenan, xanthan gum, gelatin, CMC, ethyl cellulose, etc.) added to the friction-generating aroma layer is appropriate, which ensures that the aroma particles are uniformly attached to the outer wall of the silicone rod, while avoiding excessive coating of binder which would affect the friction breakage efficiency. After rotation stops, the friction effect ends, and the amount of aroma released gradually decreases with the flow of flue gas, achieving a controllable effect of "aroma generation upon rotation and aroma reduction upon stopping rotation".

[0046] 2. Currently, many cigarette products use a silicone rod with through holes as the lip filter. The advantage is that the silicone rod doesn't turn yellow after inhalation, giving consumers the impression of clean smoke. However, its disadvantages include poor filtration efficiency and high smoke irritation. This application uses a coaxial rod with a silicone core and a cellulose acetate outer ring as the lip filter, combining the advantages of both types. It effectively filters the smoke without causing noticeable yellowing after inhalation, giving consumers the psychological feeling of inhaling clean smoke. Attached Figure Description

[0062] This application provides a cigarette with a silicone rod at the end that can produce aroma through friction. The cigarette includes a tobacco section 1, a filter section 5 and a coaxial rod 2 arranged from upstream to downstream. The coaxial rod 2 includes a silicone rod 2-1 and a fiber bundle tube 2-2 arranged from the inside to the outside.

[0063] The fiber bundle tube 2-2 includes a near-lip fiber bundle tube 2-2-1 and a far-lip fiber bundle tube 2-2-2;

[0064] The outer wall of the silicone rod 2-1 is provided with a friction fragrance-producing layer 4, so that when the near-lip section fiber bundle tube 2-2-1 is rotated, the friction fragrance-producing layer 4 can produce fragrance due to the friction of the fiber bundle tube 2-2.

[0065] Preferably, the cigarette further includes: a first outer wrapping component 2-3;

[0066] The first outer packaging 2-3 includes a proximal lip forming paper and a distal lip forming paper covering the proximal lip fiber bundle tube 2-2-1;

[0067] An adhesive layer is provided between the first outer wrapping 2-3 and the fiber bundle tube 2-2, so that when the distal lip section forming paper is rotated, the fiber bundle tube 2-2 rotates while the silicone rod 2-1 does not rotate.

[0068] Preferably, the tobacco segment 1, the filter segment 5, and the coaxial rod 2 are wrapped with a second outer wrapping element 3.

[0069] A second aspect of this application provides a method for preparing a cigarette as described in any one of the first aspects, the method comprising the following steps:

[0070] 1. By dipping in a friction-generating liquid, at least the outer wall of the silicone rod 2-1 is loaded with a friction-generating layer 4;

[0071] 2. Wrap silicone rod 2-1 with fiber bundles and shape it to obtain silicone rod 2-1 wrapped with fiber bundle tube 2-2;

[0072] 3. Wrap the silicone rod 2-1 wrapped with fiber bundle tube 2-2 with a first outer wrapping part 2-3 to obtain a preliminary coaxial rod; this step can be done by coating the outer wall of fiber bundle tube 2-1 with a widened adhesive line before wrapping with the first outer wrapping part 2-3 to enhance the bonding strength between the two.

[0073] 4. Cut the initial coaxial rod from the middle of the first outer wrapping 2-3 to the fiber bundle tube 2-2 without cutting the silicone rod 2-1;

[0074] 5. After coating the outer periphery of the preliminary coaxial rod after ring cutting in step 4 with an adhesive layer, roll it together with filter section 5 and tobacco section 1 with pre-perforated tipping paper to form a cigarette.

[0075] The pre-perforated tipping paper has a pre-perforated weak connecting line 3-1. When rolling, the weak connecting line 3-1 covers the circumferential cut position of the initial coaxial rod, so that the weak connecting line 3-1 can be broken by rotating the near-lip section fiber bundle tube 2-2-1 of the cigarette, and the near-lip section fiber bundle tube 2-2-1 and the far-lip section forming paper and tipping paper wrapped around it will rotate accordingly.

[0076] Preferably, the friction-generating fragrance liquid comprises: a binder and fragrance particles. Preferably, the friction-generating fragrance liquid also comprises a smoke-generating agent. Existing fragrance particles, whether or not they have a wall material, can be used in this application because the fragrance particles will undergo some breakage under friction.

[0077] In this application, the binder content in the friction-generating fragrance liquid is relatively low, which allows the fragrance particles to remain on the outer wall of the silicone rod without affecting the friction-breaking of the fragrance particles.

[0078] Food-grade adhesives can be selected, such as carrageenan, xanthan gum, gelatin, CMC, ethyl cellulose, etc.

[0079] Fragrance granules can be prepared using existing methods. For example, a method for preparing rose fragrance granules is as follows:

[0080] 1. Preparation of gelatin solution: Weigh 1.5g of gelatin, add 30ml of distilled water, let it swell fully, then heat and stir continuously in a 50℃ water bath until dissolved, and keep warm for later use.

[0081] 2. Preparation of gum arabic solution: Weigh 1.5g of gum arabic, which is equal in amount to gelatin, add 30ml of distilled water, heat until completely dissolved, and place in a 50℃ water bath for constant temperature.

[0082] 3. Preparation of rose fragrance emulsion: Mix 1.5g of rose fragrance with the above gum arabic solution, grind and mix in a dry mortar, then add 3ml of distilled water and grind quickly in the same direction until the initial emulsion is formed. Add 27ml of distilled water and continue grinding until uniform. Pour into a beaker and place in a 50℃ water bath for constant temperature.

[0083] 4. Encapsulation: While stirring the gelatin solution in the emulsion at a constant temperature of 50°C, continue stirring. Add an appropriate amount of 5wt% acetic acid solution dropwise until the pH reaches 4.0. At this point, microcapsule formation can be observed under a microscope. Then add acidified distilled water preheated to approximately 30°C, about twice the volume of the encapsulation system, at pH 4±4.8, to dilute and obtain a microcapsule suspension.

[0084] 5. Curing: Remove the beaker containing the microcapsule suspension from the water bath and rapidly cool it to below 10°C using an ice-water bath while stirring. Add 37wt% formaldehyde solution and stir with a magnetic stirrer for 15 minutes. Adjust the pH to 8-9 with an appropriate amount of 20wt% sodium hydroxide solution, continue stirring and cooling for 1 hour, and allow to stand until the microcapsules have completely settled. Then filter, wash with distilled water until there is no formaldehyde odor, adjust the pH to neutral, and dry under vacuum to obtain wet capsules. The wet capsules can be dried below 50°C to obtain fragrance granules.

[0085] The outer shell of the aforementioned spice particles is a gelatin-gum arabic composite coagulation film, which is formed by pH control of gelatin and gum arabic to form an electrostatic composite film. The film layer has high toughness and requires a large frictional force (such as rubbing) to trigger its rupture.

[0086] Preferably, the method for preparing the aroma-generating liquid by friction includes the following steps:

[0087] By weight, 65-75 parts ethanol, 5-10 parts fragrance, 5-10 parts of the above-mentioned fragrance granules, and 1-5 parts ethyl cellulose are stirred evenly to obtain a friction-generated fragrance liquid.

[0088] The fragrance-generating liquid produced by friction can also contain 1-5 parts by weight of a smoke-generating agent, which can be selected from glycerin or glycerol, etc.

[0089] The process of forming the silicone rod 2-1 wrapped with fiber bundle tube 2-2 can be carried out using special equipment, such as a composite extrusion molding unit.

[0090] The silicone rod conveying mechanism delivers the silicone rod 2-1 at a uniform speed and stably to the subsequent wrapping and extrusion stations, ensuring that it does not deviate or shake during the molding process.

[0091] The fiber bundle feeding and guiding system evenly releases the cellulose acetate bundles and guides them to wrap around the surface of the silicone rod at a specific angle or density.

[0092] The composite extrusion die introduces a silicone rod containing a fiber bundle into the die. The fiber bundle is shaped into a "tubular" shape by extrusion pressure or heating, while being tightly bonded to the silicone rod 2-1, without affecting the rotation of the fiber bundle segments.

[0093] The third aspect of this application provides a method of using the cigarette described in the first aspect, the method comprising: rotating the near-lip segment fiber bundle tube 2-2-1, and holding the far-lip segment fiber bundle tube 2-2-2 so that the far-lip segment fiber bundle tube 2-2-2 and the silicone rod 2-1 do not rotate;

[0094] Then the distal lip segment fiber bundle tube 2-2-2 and the friction fragrance-producing layer 4 rub against each other, causing the friction fragrance-producing layer 4 to produce fragrance.

[0095] Preferably, the aroma-producing layer 4 produces fragrance due to frictional heat, and / or the fragrance particles within the aroma-producing layer 4 are broken due to friction, thus producing fragrance.

[0096] For example, the outer shell of the fragrance particles in the friction-generating fragrance layer 4 may crack due to friction, causing the fragrance in the core of the fragrance particles to be released, and / or the temperature may rise due to friction, thus accelerating the release of fragrance.

[0097] Preferably, the rotational force is 3-10 N·cm, and the rotation time is 5-30 s. The temperature of the friction contact surface of the friction-generating fragrance layer 4 increases by 3-8℃, with a maximum temperature ≤40℃.

[0098] Figure 1 This is a schematic diagram of the first structure of the cigarette stick in this application. Figure 2 This is a schematic diagram of the second structure of the cigarette stick in this application. Figure 3 This is a schematic diagram of the coaxial rod structure of this application.

[0099] The first outer wrapping component 2-3 is formed paper. The second outer wrapping component 3 is tipping paper. The fiber bundle tube 2-2 is a cellulose acetate fiber bundle tube. The fiber bundle tube 2-2 also serves to filter flue gas. The filter section 5 is a solid cellulose acetate fiber bundle rod.

[0100] The following are several specific embodiments to demonstrate the effectiveness of this application.

[0101] Example 1

[0102] 1. Structure of each component of the cigarette:

[0103] Silicone rod 2-1: 5mm in diameter, 20mm in length, porous structure (40% porosity), with menthol as an auxiliary fragrance impregnated within the pores; this silicone rod is obtained by injection molding.

[0104] Fragrance-generating liquid by friction: 2 parts ethyl cellulose, 10 parts of the above-mentioned rose fragrance granules, 10 parts fragrance, 75 parts ethanol, and 3 parts propylene glycol; parts are by weight.

[0105] Fiber acetate bundle tube 2-2: length 20mm, inner wall roughness Ra=1.0μm, tube wall thickness 1.1mm;

[0106] First outer packaging component 2-3: Forming paper (28g / m²) 2 Second outer wrapping component 3: tipping paper (35g / m²) 2 ).

[0107] Tobacco Segment 1: Regular flue-cured tobacco shreds, 60mm in length, including tobacco paper wrapping.

[0108] Filter section 5: 10mm in length, solid cellulose acetate bundle rod, wrapped in forming paper.

[0109] 2. The preparation steps of the cigarette are as follows:

[0110] 1) A friction-generating fragrance layer 4 is obtained by immersing a 0.2 mm thick friction-generating fragrance liquid on the outer wall of the silicone rod 2-1;

[0111] 2) Wrap silicone rod 2-1 with fiber bundles to form silicone rod 2-1 wrapped with fiber bundle tube 2-2;

[0112] 3) Wrap the silicone rod 2-1, which is wrapped by the fiber bundle tube 2-2, with a first outer wrapping part 2-3 to obtain a preliminary coaxial rod; in this step, the outer wall of the fiber bundle tube 2-2 is coated with a widened adhesive line before wrapping with the first outer wrapping part 2-3 to enhance the bonding strength between the two; the width of the widened adhesive line is 2-5mm, and in this embodiment it is 5mm;

[0113] 4) The initial coaxial rod is circumferentially cut from the middle of the first outer wrapping 2-3 to the fiber bundle tube 2-2 without cutting the silicone rod 2-1; the cutting depth is 1.1 mm. In this application, the cutting device adopts a vertical milling machine with depth control, and the depth control accuracy can reach 0.01 mm, completely avoiding cutting the inner tube. The fiber bundle tube 2-2 is cut into a near-lip section fiber bundle tube 2-2-1 and a far-lip section fiber bundle tube 2-2-2.

[0114] 5) The preliminary coaxial rod after ring cutting in step 4, filter section 5, and tobacco section 1 are rolled together with pre-perforated tipping paper to form a cigarette.

[0115] The pre-perforated tipping paper has a pre-perforated weak connecting line 3-1. When rolling, the weak connecting line 3-1 covers the circumferential cut position of the initial coaxial rod, so that the weak connecting line 3-1 can be broken by rotating the near-lip section fiber bundle tube 2-2-1 of the cigarette, and the near-lip section fiber bundle tube 2-2-1 and the far-lip section forming paper and tipping paper wrapped around it will rotate accordingly.

[0116] Comparative Example 1

[0117] The difference from Example 1 is that the coaxial rod in Example 1 is directly replaced with a solid cellulose acetate bundle of the same length. That is, the solid cellulose acetate bundle is wrapped with forming paper, and then rolled together with filter section 5 and tobacco section 1 with tipping paper to form a cigarette.

[0118] Sensory evaluation test: According to the national standard GB5606.4-2005 "Cigarettes Part 4: Sensory technical requirements", the cigarette samples of Example 1 and Comparative Example 1 were subjected to sensory evaluation under the same conditions.

[0119] The cigarettes were evaluated by multiple sensory evaluators, primarily assessing six indicators: gloss, aroma, harmony, off-flavors, irritation, and aftertaste. The scoring values ​​for these six quality indicators were as follows: gloss 0-5 points, aroma 0-32 points, harmony 0-6 points, off-flavors 0-12 points, irritation 0-20 points, and aftertaste 0-25 points. The total score for the six indicators was 100 points. Higher scores for gloss, aroma, harmony, and aftertaste indicated a stronger sensory experience for that indicator. Higher scores for off-flavors and irritation indicated a less pronounced sensory experience for those indicators during smoking. A higher total score across all six indicators represented a better smoking experience.

[0120] Three sets of cigarette samples were prepared for both Example 1 and Comparative Example 1.

[0121] Example 1-1# The smoking method of cigarette is as follows: After lighting, rotate the fiber bundle tube near the lip section 2-2-1 five times and then inhale until the inhalation is complete.

[0122] Example 1-2# The smoking method of cigarettes is as follows: After lighting, rotate the fiber bundle tube near the lip section 2-2-1 five times, take two puffs, then rotate the fiber bundle tube near the lip section 2-2-1 five times, and continue to smoke until the smoking is finished.

[0123] The smoking method for cigarettes in Examples 1-3 is as follows: After lighting, rotate the fiber bundle tube near the lip section 2-2-1 five times, take two puffs, then rotate the fiber bundle tube near the lip section 2-2-1 five times, take two puffs, then rotate the fiber bundle tube near the lip section 2-2-1 five times, and continue smoking until the smoking is finished.

[0124] Each rotation causes the proximal lip segment fiber bundle 2-2-1 to rotate 90 degrees around the center of the silicone rod 2-1. During rotation, the distal lip segment fiber bundle 2-2-1 and the silicone rod 2-1 remain stationary.

[0125] The three groups of cigarettes in Comparative Example 1 were directly lit and inhaled.

[0126] The sensory evaluation scores of the cigarette samples from Example 1 and Comparative Example 1 are shown in Table 1.

[0127]

[0128]

[0129] Table 1 above illustrates that: 1. Compared to Comparative Example 1, the cigarette of Example 1 has a higher overall sensory evaluation. 2. The smoking and rotating methods of Example 3 have a higher sensory evaluation. This indicates that the friction-generating aroma layer 4 of this application can continuously replenish aroma with rotation throughout the smoking process of the cigarette.
