Description

Technical Field

[0001] This invention belongs to the field of cigarette technology, specifically relating to a combustion component, its preparation method, and its application. Background Technology

[0002] Heated cigarettes produce nicotine-containing smoke simply by heating, primarily from reconstituted tobacco leaves or shredded tobacco loaded with a smoke-generating agent under heating conditions. Heated cigarettes include electrically heated cigarettes and charcoal-heated cigarettes. Because they are similar to traditional cigarettes in terms of smoking method, physiological and psychological perception, and have advantages such as lower levels of harmful components in the aerosol produced by heating, they have gained widespread consumer acceptance, and the market size has been expanding year by year.

[0003] CN217826765U discloses an electrically heated cigarette, comprising: a smoke-generating section; the smoke-generating section abutting against a heating base in a smoking device; a flavoring section disposed inside the smoke-generating section, and at the abutment point between the smoke-generating section and the heating base; a flavoring capsule disposed within the flavoring section, the flavoring capsule being used to engage with a spike on the heating base to flavor the electrically heated cigarette. An electrically heated smoking device is also disclosed. Since this electrically heated smoking device needs to be used in conjunction with the aforementioned electrically heated cigarette, it should therefore possess the same beneficial effects as the electrically heated cigarette. This device has a simple structure, is safe, effective, reliable, and easy to operate. It effectively preserves flavorings for a long time and releases the stored flavorings during inhalation, improving the user's sensory experience.

[0004] CN113907446A discloses a charcoal-heated cigarette, comprising a charcoal rod segment, a tobacco segment, a smoke extraction segment, and a filter segment arranged sequentially from upstream to downstream. The charcoal-heated cigarette may further include composite paper and an external wrapping element wrapped around the composite paper, tobacco segment, smoke extraction segment, and filter segment. The composite paper wraps a portion of the charcoal rod segment and a portion or all of the tobacco segment. The smoke extraction segment has a cavity extending in the axial direction, and its sidewalls have at least one sidewall through-hole communicating with the cavity. The external wrapping element has a wrapping element through-hole at a position corresponding to the sidewall through-hole, allowing external air to enter the smoke extraction segment. The charcoal-heated cigarette of the present invention allows air to bypass the tobacco segment during inhalation, thereby maintaining the tobacco material within a certain temperature range and ensuring the composition and concentration of the mainstream smoke.

[0005] However, electrically heated cigarettes require a heating device to provide a heat source, which is inconvenient. Charcoal-heated cigarettes provide heat by igniting a charcoal stick, which is encased in insulation material. Firstly, the burning status of the charcoal stick is not visible from the outside of the cigarette, making it impossible for consumers to determine whether the charcoal stick has been fully burned, posing a safety hazard. Secondly, the strong CO odor produced by the burning charcoal stick results in a poor sensory experience, leading to low market acceptance. Charcoal-heated cigarettes were withdrawn from the market shortly after their introduction. Therefore, designing a heated cigarette that does not require a heating device, providing an efficient heat source while eliminating safety concerns, has become a focus of attention in this industry. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a combustion firmware, its preparation method, and its application. The combustion firmware can provide an efficient heat source and has no safety hazards in its use.

[0007] To achieve this objective, the present invention employs the following technical solution:

[0008] In a first aspect, the present invention provides a combustion firmware, the raw materials for which the combustion firmware is prepared include modified fibers, carbon powder, molding agent, metal oxide and inorganic salt.

[0009] The combustion component provided by this invention provides a heat source for the aerosol generation section through ignition. Compared to electrically heated cigarettes, this invention does not require a heating device; compared to charcoal-heated cigarettes, the combustion component provides a heat source through ignition, and the combustion process can be visually observed, effectively improving safety. The combustion component of this invention uses a cylinder with porous channels, which effectively transfer heat to the aerosol generation section during ignition and inhalation. In particular, the addition of copper oxide to the combustion component allows it to react with CO produced by incomplete combustion of the component, reducing the CO content in the aerosol. Furthermore, copper oxide's thermal conductivity also improves the heat transfer efficiency after ignition.

[0010] In addition, the fibers in the combustion firmware of the present invention are modified to remove impurities and alcohol-soluble components from the material, thereby significantly reducing the impurities and irritation of the mainstream flue gas after the firmware is burned.

[0011] Preferably, the combustion fastener comprises, by weight, 60-70 parts modified fiber, 3-20 parts charcoal powder, 1-15 parts molding agent, 1-5 parts metal oxide and 0.1-5 parts inorganic salt.

[0023] The combustion firmware of the present invention incorporates potassium permanganate, which decomposes under heating conditions to generate oxygen, thereby further improving the combustion efficiency of the firmware. Consequently, when used to heat cigarettes, the heat can be transferred to the aerosol generation section more effectively.

[0028] Preferably, the mixing in step (2) is carried out by stirring, and the stirring temperature is 40-50℃ (e.g., 41℃, 43℃, 45℃, 47℃ or 49℃, etc.), and the time is 15-45min (e.g., 20min, 25min, 30min, 35min or 40min, etc.).

[0031] Preferably, the mold-fixed combustion fastener is a cylindrical fastener with multiple porous channels.

[0032] Preferably, the porous channel is a straight channel and / or a rotating channel.

[0033] Thirdly, the present invention provides an application of the combustion fixture as described in the first aspect in the preparation of heated cigarettes.

[0034] Fourthly, the present invention provides a heated cigarette, the heated cigarette comprising a combustion section, an aerosol generating section, and a filter section;

[0035] The combustion section is the combustion firmware described in the first aspect.

[0036] All the specific point values ​​within the above range can be selected, and will not be elaborated on here.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] The combustion component provided by this invention provides a heat source for the aerosol generation section through ignition. Compared to electrically heated cigarettes, this invention does not require a heating device; compared to charcoal-heated cigarettes, the combustion component provides a heat source through ignition, and the combustion process can be visually observed, effectively improving safety. The combustion component of this invention uses a cylinder with porous channels, which effectively transfer heat to the aerosol generation section during ignition and inhalation. Furthermore, the addition of copper oxide to the combustion component allows it to react with CO produced by incomplete combustion of the component, reducing the CO content in the aerosol. Copper oxide also has thermal conductivity, further improving heat transfer efficiency after ignition. Additionally, the modified fibers not only reduce odors from fiber combustion but also significantly reduce tar produced during combustion. Combined with the tar interception and adsorption effect of the aerosol generation section, this results in a low-harm advantage for the combustion-type heated cigarette. Attached Figure Description

[0104] Application Example 1

[0105] This application example provides a heated cigarette, which comprises a combustion section, an aerosol generating section, and a filter section in sequence; the combustion section is the combustion component provided in Example 1. The core material of the aerosol generating section is reconstituted tobacco, and the reconstituted tobacco contains 15% glycerol by mass.

[0106] Application Example 2-8

[0107] Application Examples 2-8 provide seven types of heated cigarettes, which differ from Application Example 1 only in that the combustion section is provided by the combustion firmware in Examples 2-8, while the rest of the structure is the same as that in Application Example 1.

[0109] The comparative application examples 1-4 provide four types of heated cigarettes, which differ from application example 1 only in that the combustion section is provided by the combustion firmware of comparative examples 1-4, and the rest of the structure is the same as application example 1.

[0110] Comparative Application Example 5

[0111] This comparative example provides a heated cigarette, the structure of which consists of an aerosol generating section, a cooling section, and a filter section in sequence. The heated cigarette is an electrically heated cigarette, and the heated cigarette device is also an electrically heated device. The core material of the aerosol generating section is the same as in Application Example 1.

[0112] Test Example 1: Comparison of the release of harmful chemical components in flue gas

[0113] The release of harmful chemical components from the smoke of heated cigarettes provided in Application Examples 1-8 and Comparative Application Examples 1-5 was tested.

[0114] Test method:

[0115] The tar content of heated cigarettes is determined according to GB / T 19609-2004. The tar content is the test result after deducting the moisture, nicotine and smoke-generating agent (glycerol) content from the total particulate matter content.

[0116] The CO content is determined according to GB / T 23356-2009, Determination of Carbon Monoxide in the Gas Phase of Cigarette Smoke by Non-scattering Infrared Method.

[0117] The results are shown in Table 1 below:

[0118] Table 1

[0119]

[0120] As can be seen from the data in Table 1, compared with conventional heated cigarettes (comparative application example 5), the heated cigarettes prepared in application examples 1-4 of the present invention can significantly reduce the harmful components in the smoke due to the use of specific combustion components as the combustion section.

[0121] As can be seen from the comparison between Application Example 1 and Comparative Application Example 2, adding copper oxide can react with CO produced by the incomplete combustion of the burning fixture, thereby reducing the CO content in the aerosol. In addition, copper oxide has thermal conductivity, which can also improve the heat transfer efficiency after the burning fixture is ignited.

[0122] Test Example 2 Sensory Quality

[0123] The sensory quality of the heated cigarettes provided in Application Examples 1-8 and Comparative Application Examples 1-5 was tested.

[0124] Test method: Refer to national standard GB 5606.4-2005.

[0125] Test standards: The scoring range for smoke volume is 1-25 points, the scoring range for harmony is 1-25 points, the scoring range for impurities is 1-25 points, the scoring range for irritation is 1-25 points, and the total score is 100 points.

[0126] The results are shown in Table 2.

[0127] Table 2

[0128]

[0129] As can be seen from Table 2, the heated cigarettes provided in Application Examples 1-4 of the present invention have excellent performance in terms of smoke volume, impurities, harmony, and irritation.

[0130] As can be seen from the comparison between Application Example 1 and Application Examples 5-6, and Comparative Application Example 1, only by modifying the fiber raw material and using the modification method of the present invention can the sensory quality of cigarettes be improved.

[0131] As can be seen from the comparison between Application Example 1 and Application Examples 7-8, when the inorganic salt added to the raw material formula is potassium permanganate, the metal oxide is copper oxide, and the main raw material is modified fiber, the combustion efficiency of the combustion fixture can be improved, thereby making the amount of aerosol smoke more sufficient.

[0132] As can be seen from the comparison between Application Example 1 and Comparative Application Example 3, when charcoal powder is lacking, the combustion heat of the combustion components is low, which cannot maximize the heat source for the aerosol generation section, resulting in poor sensory quality of heated cigarettes.

[0133] As can be seen from the comparison between Application Example 1 and Comparative Application Example 4, the combustion efficiency of the combustion firmware is better when fiber is added, which can maximize the improvement of flue gas quality.
