Description

Technical Field

[0001] The present application belongs to the technical field of cigarettes, and more specifically, relates to a cigarette filter and a cigarette that combines a scent cord and a fastener. Background Art

[0002] Cigarette filters are a key component of cigarettes. Their main function is to filter harmful substances in smoke, reduce the amount of tar and nicotine inhaled by smokers, and thus reduce the potential health hazards of smoking.

[0003] As consumer demand continues to evolve and upgrade, cigarette filters are also evolving, manifesting in innovations in materials, structures, and product diversification. For example, to enrich the sensory quality of cigarette smoking, scented filters are embedded with a material that absorbs and retains aromas, offering smokers additional aroma experiences beyond traditional tobacco flavors, such as natural or synthetic flavors like vanilla and mint. Custom-shaped filters can also offer a different consumer experience, attracting consumers through unique designs while also providing additional functionality or enhancing the smoking experience.

[0004] Currently, the flavor experience of string filters on the market is weak, while fixed filters are often used as a means of attracting consumers or competing through visual differentiation. Furthermore, the problem of excessively high smoke temperature in the last few puffs of cigarettes remains difficult to effectively address. Therefore, how to maximize the smoking experience of string filters and effectively control smoke flavor and temperature using fixed filters are urgent challenges in the current tobacco technology field. Summary of the Invention

[0005] In view of the above-mentioned deficiencies in the prior art, the embodiment of the present application aims to provide a cigarette filter that combines a fragrance cord and a fastener.

[0006] To achieve the above-mentioned purpose, the technical solution adopted in this application is: to provide a cigarette filter combining a fragrance cord and a firmware, characterized in that it includes a firmware and an acetate fiber bundle segment wrapped by forming paper; a fragrance cord is provided on the central axis of the acetate fiber bundle segment, and the firmware is provided with a central through hole and a plurality of outer ring through holes arranged around the central through hole.

[0007] In one embodiment, at least four outer ring through holes are arranged at equal arc distances.

[0008] In one embodiment, six outer ring through holes are arranged at equal arc distances.

[0009] In one embodiment, the diameter of the central through hole is larger than the diameter of the outer ring through holes, the diameter of the central through hole is 2.2-2.8 mm, and the diameter of the outer ring through holes is 1.2-1.8 mm.

[0010] In one embodiment, the diameter of the central through hole is smaller than that of the outer ring through holes. The diameter of the central through hole is 0.8-1.4 mm, and the diameter of the outer ring through holes is 1.5-2.5 mm.

[0011] In one embodiment, the aperture of the central through hole is equal to the aperture of the outer ring through hole, and the aperture range is 1.2-2.4 mm.

[0012] In one embodiment, the apertures of the outer ring through holes and the central through hole are different, and the aperture range is 0.4-4 mm.

[0013] In one embodiment, the length of the fastener is 4-28 mm.

[0014] In one embodiment, the diameter of the incense thread is smaller than the diameter of the central through hole.

[0015] Another object of this embodiment is to provide a cigarette, comprising a tobacco segment and a cigarette filter combined with a scent cord and a fastener as described above, wherein the tobacco segment and the filter are wrapped by tipping paper.

[0016] The cigarette filter and cigarette stick combined with the incense cord and the fastener provided in this application have the following beneficial effects:

[0017] 1. By combining the incense thread and the firmware, and using the central through hole and outer circle through holes in the firmware to divert the smoke, the high-concentration aerosol smoke in the center enters the central through hole, and the low-concentration aerosol smoke outside the center enters the outer circle through holes. After the smoke is redistributed by the firmware, the aerosol concentration stratification is more significant, and the aerosol particle number median particle size stratification is also more significant, thereby achieving effective regulation of the smoke aerosol concentration and particle size.

[0018] 2. The firmware is made of silicone material with high specific heat capacity, which can effectively reduce the smoke temperature and prevent consumers from being burned by the high temperature in the last few puffs of smoke.

[0019] 3. By combining the acetate fiber segment containing the fragrance thread with the firmware, the smoke containing high-concentration aroma substances flowing from the acetate fiber segment into the firmware enters the central through hole of the firmware, and the smoke containing low-concentration aroma substances enters the outer ring through holes of the firmware, so that the smoke containing aroma substances has a higher speed in the central through hole of the firmware and the aroma substances are more concentrated, and the aroma experience is better.

[0030] like Figure 1-Figure 3 As shown, a cigarette filter tip that combines a scent cord and a fixture 1 provided in an embodiment of the present application will now be described. The cigarette filter tip that combines a scent cord and a fixture comprises a fixture 1 and an acetate fiber bundle segment 2 wrapped by a forming paper 3; a scent cord 21 is provided on the central axis of the acetate fiber bundle segment 2, and the fixture 1 is provided with a central through hole 11 and a plurality of outer ring through holes 12 arranged around the central through hole 11. The smoke flows from the outlet of the acetate fiber segment through the central through hole 11 and the outer ring through holes 12 into the oral cavity of the smoker, so that the speed of the smoke increases after entering the fixture 1. The fixture 1 is made of silicone. When the cigarette is inhaled to the 7th puff and the following puffs, the smoke temperature gradually increases. The use of a fixture 1 with a higher specific heat capacity can effectively reduce the smoke temperature, thereby preventing the smoke temperature from being too high in the following puffs and scalding the consumer.

[0031] The fragrance cord 21 is a fragrance cord loaded with a certain aroma substance, which can be used to increase the amount of aroma substance in cigarette smoke.

[0032] There are at least four outer ring through holes 12 arranged at equal arc distances. Specifically, there are six outer ring through holes 12 arranged at equal arc distances.

[0033] In the first embodiment, the diameter of the central through hole 11 is larger than that of the outer ring through holes 12. The diameter of the central through hole 11 is 2.2-2.8 mm, and the diameter of the outer ring through holes 12 is 1.2-1.8 mm. In this way, the smoke velocity in the central through hole 11 is lower than that in the outer ring through holes 12.

[0034] In the second embodiment, the diameter of the central through hole 11 is smaller than that of the outer ring through holes 12. The diameter of the central through hole 11 is 0.8-1.4 mm, and the diameter of the outer ring through holes 12 is 1.5-2.5 mm. In this way, the smoke velocity in the central through hole 11 is greater than that in the outer ring through holes 12.

[0035] In the third embodiment, the diameter of the central through hole 11 is equal to that of the outer ring through holes 12, and the diameter range is 1.2-2.4 mm. In this way, the flue gas velocity in the central through hole 11 is substantially the same as that in the outer ring through holes 12.

[0036] In the fourth embodiment, the diameters of the outer ring through holes 12 and the central through hole 11 are different, and the diameter range is 0.4-4 mm. In this way, the flue gas velocity in the central through hole 11 is different from the velocity in the outer ring through holes 12.

[0037] In this embodiment, the length of the fixing member 1 is 4-28 mm. The diameter of the incense thread 21 is smaller than the diameter of the central through hole 11.

[0038] This embodiment also provides a cigarette, comprising a tobacco segment 4 and the cigarette filter as described above, wherein the tobacco segment 4 and the filter are wrapped by tipping paper 5 . Since the tipping paper 5 has a certain air permeability, the smoke aerosol is diluted by the external air in the tobacco segment 4, and the concentration of the smoke aerosol entering the filter shows a trend of gradually decreasing from the center to the periphery along the radial direction of the filter. The structural design of the central through hole 11 and the outer ring through holes 12 in the firmware 1 allows the high-concentration aerosol smoke in the center to enter the central through hole 11, and the low-concentration aerosol smoke outside the center to enter the outer ring through holes 12. A higher aerosol particle number concentration will increase the probability of aerosol coagulation and increase the median particle size of the aerosol particles. Conversely, a lower aerosol particle number concentration will reduce the probability of aerosol coagulation and reduce the median particle size of the aerosol particles. Therefore, after the smoke flows through the firmware 1 section with this structural design, the stratification phenomenon of the smoke aerosol concentration distribution is more obvious and the difference in the median particle size distribution of the aerosol particles is greater, thereby achieving effective regulation of the smoke aerosol concentration and particle size.

[0039] This embodiment provides an embodiment 1 of a specific parameter:

[0040] Example 1:

[0041] In this embodiment 1, the firmware 1 is provided with a central through hole 11 and 6 evenly arranged outer ring through holes 12. The inner diameter of the central through hole 11 is larger than that of the outer ring through holes 12. The outer ring through holes 12 have the same aperture size. The aperture of the central through hole 11 is 2.5 mm, and the aperture of the outer ring through holes 12 is 1.5 mm. The length of the firmware 1 is 8 mm and the diameter is 7.4 mm.

[0042] During use, the end of the tobacco segment 4 of the cigarette is ignited, and the user draws on the end of the filter. The smoke generated by the burning tobacco segment 4 flows through the tobacco segment 4, the filter acetate bundle segment 2 and the fixture 1 in sequence. When the smoke flows through the filter acetate bundle, the tobacco or acetate bundle in the tobacco segment 4 and the acetate bundle segment 2 are arranged more evenly. The smoke is still close to a laminar flow state when flowing through the tobacco segment 4 and the acetate bundle segment 2. After the smoke enters the fixture 1, the effective flow area of ​​the fixture 1 is reduced, and the speed of the smoke inside the fixture 1 is significantly increased, which increases the probability of collision and condensation of the smoke aerosol in the central through hole 11. In addition, the fragrance line 21 in the acetate bundle segment 2 and the central through hole 11 of the fixture 1 are located on the same central axis. The diameter of the fragrance line 21 is significantly smaller than the inner diameter of the central through hole 11, and the fragrance released by the fragrance line 21 The aroma substance diffuses toward the wall of the filter tipping paper 5 along the axial aroma line 21 of the center line, and the aroma concentration tends to decrease radially from the middle to the wall of the filter tipping paper 5. Therefore, the concentration of aroma substances in the smoke flowing through the central through hole 11 of the firmware 1 is higher than that in the outer circle through hole 12. Since the inner diameter of the central through hole 11 is larger than that of the outer circle through hole 12, the speed of the smoke in the central through hole 11 is smaller than that in the outer circle through hole 12. On the one hand, the difference in the speed of the outflowing smoke from the central through hole 11 and the outer circle through hole 12 will aggravate the disturbance of the smoke airflow and further increase the probability of collision and condensation of smoke aerosols. On the other hand, the concentration of aroma substances in the smoke in the central through hole 11 is higher than that in the outer circle through hole 12. The smaller speed will cause the high concentration of aroma substances to diffuse from the center of the smoke to the walls of the oral cavity and nasal cavity of the smoker at a relatively slow speed.

[0043] Since the tipping paper 5 has a certain air permeability, the smoke aerosol is diluted by the external air in the tobacco segment 4, and the concentration of the smoke aerosol entering the filter shows a trend of gradually decreasing from the center to the periphery along the radial direction of the filter. The addition of the firmware 1 allows the high-concentration aerosol smoke in the center to enter the central through hole 11, and the remaining low-concentration aerosol smoke enters the outer circle through holes 12, which will prevent the exchange of smoke gas phase and aerosol particles between the center and the surrounding area, so that the aerosol concentration stratification is more severe after the smoke is redistributed through the central through hole 11 and the outer circle through holes 12 of the firmware 1; in addition, a higher aerosol particle number concentration will increase the probability of aerosol coagulation and increase the median particle size of the aerosol particles. The median particle size of the smoke aerosol flowing through the central through hole 11 of the firmware 1 is larger than that flowing through the outer circle through holes 12 of the firmware 1. Therefore, after the smoke is redistributed through the central through hole 11 and the outer circle through holes 12 of the firmware 1, the stratification phenomenon of the median particle size of the smoke aerosol particles is also more severe.

[0044] The smoking temperature of the cigarette in Example 1 is compared with that of a conventional acetate filter:

[0045] Under the ISO standard method, the smoke outlet temperature of the filter tip after 6 puffs remains at a reduced level, and consumers can use it normally. However, as the burning line of the cigarette tobacco segment continues to approach the filter tip, the smoke temperature will increase significantly. The cigarette 2# having the filter tip structure of Example 1 and the ordinary acetate filter plug cigarette 1# were smoked according to the same ISO standard method, with the puff termination set at 9 puffs. The maximum smoke temperature of the tested filter tips is shown in Table 1:

[0046] Table 1

[0047]

[0048] As can be seen from Table 1, during cigarette smoking, the maximum smoke temperature is below 30°C during the first 7 puffs, which is close to the length of the cigarette butt, and is no different from room temperature. However, some consumers may continue to smoke, at which point the smoke temperature of ordinary acetate filter cigarettes will rise significantly, reaching around 60°C. In comparison, the maximum smoke temperature of the filter tip of Example 1 is still around 30°C. This shows that cigarettes using firmware filters can effectively reduce the maximum temperature of cigarette smoke and improve consumers' smoking experience.

[0049] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
