Abstract
Description
Technical Field
[0001] This invention belongs to the field of heated cigarette technology, specifically relating to a heated cigarette that can be smoked multiple times. Background Technology
[0002] Heated tobacco products have become an important development direction for the tobacco industry in recent years. Their basic principle is to heat the tobacco material inside a specially made cigarette at a relatively low temperature (usually 200°C to 350°C) using an external heat source, releasing volatile components such as nicotine and flavoring substances into an aerosol for the consumer to inhale. Compared to traditional combustible cigarettes, heated tobacco products significantly reduce the harmful components produced by high-temperature combustion, and are therefore considered a product with potential for harm reduction.
[0003] Current heated tobacco products typically consist of a filter section and a tobacco material section (or smoke-generating section). During use, the entire tobacco material section is heated to the target temperature continuously and in one go. From the start to the end of the smoke, the cigarette remains heated until the active ingredients in the tobacco material are largely released. This "one-time, whole-unit heating" working mode is commonly used in mainstream products on the market.
[0004] The "one-time whole-cycle heating" working mode has advantages such as technical simplicity and similarity to the traditional cigarette smoking mode, but it also has obvious drawbacks. First, the one-time whole-cycle heating mode limits the flexibility of use. Once a cigarette is heated, it must be consumed in a single use, which cannot meet the user's need to smoke the same cigarette multiple times at different times. For consumers with low smoking demand or who wish to enjoy cigarettes intermittently, this causes unnecessary waste and affects the user's consumption experience. Second, the existing technology for heating cigarettes has a long preheating time each time, and each cigarette can only be smoked 10-12 times, leading to problems such as frequent cartridge replacement, poor smoking evenness, etc.
[0005] Therefore, there is an urgent need in this field for an innovative heated cigarette design that can overcome the aforementioned drawbacks of the "one-time overall heating" working mode, with a short preheating time, the ability to adjust the time of a single puff, the number of puffs, and the time interval between two puffs according to the consumer's smoking habits, eliminating the hassle of frequently changing tobacco cartridges, avoiding waste of tobacco cartridges, and ensuring that every puff provides a stable quality and good experience, truly realizing an intelligent working mode that is customized for consumers, and greatly improving the consumer experience. Summary of the Invention
[0006] To address the shortcomings of existing technologies, this invention provides a heated cigarette that can be smoked multiple times. This heated cigarette solves the problems of excessively long preheating time, frequent cartridge replacement, or cartridge waste associated with conventional heated cigarettes, and also ensures better smoking consistency.
[0007] To achieve this objective, the present invention adopts the following technical solution: In a first aspect, the present invention provides a heated cigarette that can be smoked multiple times, wherein the raw materials for preparing the heated cigarette are tobacco raw materials and atomizing agents; The method for preparing the heated cigarette includes: mixing tobacco raw materials and atomizing agent and placing them into a rectangular mold, and then extruding them using an extruder to obtain a compacted rectangular cigarette rod, which is the heated cigarette. The density of the rectangular tobacco stick is 5-10 g / cm³. 3 For example, it can be 5.5g / cm³. 3 6 g / cm 3 6.5 g / cm 3 7g / cm 3 7.5 g / cm 3 8 g / cm 3 8.5 g / cm 3 9 g / cm 3 Or 9.5 g / cm 3 wait; The heated cigarette is smoked 50 times or more.
[0008] Preferably, the raw materials for preparing the heated cigarette, by weight, are 60-85 parts of tobacco raw material (e.g., 61, 63, 65, 67, 70, 72, 75, 78, 80, 82, or 84 parts, etc.) and 15-40 parts of atomizing agent (e.g., 16, 18, 20, 22, 25, 28, 30, 32, 35, or 38 parts, etc.).
[0009] Preferably, the tobacco raw material includes any one or a combination of at least two of the following: shredded tobacco, shredded stems, or reconstituted tobacco leaves.
[0010] Preferably, the tobacco shreds include any one or a combination of at least two of the following: flue-cured tobacco leaves, burley tobacco leaves, sun-cured tobacco leaves, or air-cured tobacco leaves.
[0011] Preferably, the atomizing agent comprises any one or a combination of at least two of glycerol, propylene glycol, butanediol, trimethylolpropane, trimethylolethane, triethylene glycol, sorbitol, xylitol, betaine, 1,2-propanediol, or 1,3-butanediol.
[0012] Preferably, the atomizing agent is a combination of glycerol, propylene glycol and xylitol.
[0013] In this invention, glycerin has high vaporization efficiency at low temperatures, producing ample and fine smoke; propylene glycol can regulate the smoke concentration and alleviate oral irritation caused by tobacco components (such as nicotine and organic acids); xylitol has a natural sweetness that can neutralize the slight bitterness or off-flavors of tobacco. When combined with the vaporized smoke from glycerin and propylene glycol, it can refine aerosol particles, making the smoke smoother and improving the smoothness of inhalation. In addition, since the heated cigarette of this invention can be inhaled multiple times, the addition of xylitol can further reduce the burning sensation of the smoke, meeting the comfort requirements of multiple inhalations.
[0014] Preferably, the cuboid cigarette rod has an area of 100-400 mm² on its upper and lower surfaces. 2 (For example, it can be 150 mm) 2 200 mm 2 250 mm 2 300 mm 2 or 350 mm 2 (etc.), with a thickness of 1mm-10mm (for example, it can be 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm or 9mm, etc.).
[0015] Preferably, the volume of the heated cigarette heated each time is 0.2-1% of the volume of the rectangular cigarette rod, for example, it can be 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8% or 0.9%, etc.
[0016] Preferably, the number of times the heated cigarette is smoked is 100-200 times, for example, 110 times, 120 times, 130 times, 140 times, 150 times, 160 times, 170 times, 180 times or 190 times.
[0017] Preferably, the raw materials for preparing the heated cigarette also include tobacco flavoring and adhesives.
[0018] Preferably, the raw materials for preparing the heated cigarette, by weight, further include 1-10 parts of tobacco flavoring (e.g., 2, 3, 4, 5, 6, 7, 8, or 9 parts, etc.) and 0.5-5 parts of adhesive (e.g., 1, 1.5, 2, 2.5, 3, 3.5, 4, or 4.5 parts, etc.).
[0019] Preferably, the tobacco flavoring comprises any one or a combination of at least two of the following: sweet orange oil, lemon oil, vanillin, succinate, 2-acetylpyrazine, 2,3,5-trimethylpyrazine, isoamyl isovalerate, menthyl acetate, phenethyl alcohol, furanone, or geraniol.
[0020] Preferably, the tobacco flavoring is a combination of vanillin, isoamyl isovalerate, and menthyl acetate.
[0021] In this invention, a combination of vanillin, isoamyl isovalerate, and menthyl acetate is selected. Vanillin provides the core vanilla sweetness with a slight milky texture, giving the aroma a "richness" and neutralizing the thinness of other spices. Isoamyl isovalerate releases ripe fruit aromas, injecting "freshness" into the sweet base and preventing the aroma from being too dull. Menthyl acetate provides a cool and refreshing sensation (milder than menthol, without any irritation), reducing the sweetness and prolonging the aroma's lingering time in the mouth. The combination of these three ingredients results in a superior sweet aroma. Furthermore, when used in conjunction with the tobacco raw materials selected in this invention, they balance the richness, soften the irritation, and mask impurities, thereby improving the taste of the heated cigarette.
[0022] Preferably, the adhesive comprises any one or a combination of at least two of sodium alginate, sodium carboxymethyl cellulose, methyl cellulose, hydroxypropyl methyl cellulose, microcrystalline fiber powder, chitosan, xanthan gum, guar gum or cellulose acetate.
[0023] Preferably, the adhesive is a combination of sodium alginate, sodium carboxymethyl cellulose, and xanthan gum.
[0024] The three adhesives used in this invention are all natural high-molecular-weight polysaccharides with thermal decomposition temperatures generally exceeding 350°C, far higher than the heating temperature of heated cigarettes. They do not produce additional harmful components such as aldehydes or benzene compounds due to their own decomposition. Furthermore, the viscosity of xanthan gum changes with shear force during heating, which can regulate the flow rate of the atomizing agent and avoid the problems of "explosive smoke" in the early stage or "insufficient smoke" in the later stage of heated cigarettes. The gel network of sodium alginate can encapsulate the natural aroma components of tobacco, nicotine, and tobacco flavoring components. During heating, it slowly swells and releases as the gel expands, prolonging the duration of aroma and improving the consistency of inhalation. The pores formed by the heating of sodium carboxymethyl cellulose can serve as "smoke channels" and simultaneously adsorb some of the atomizing agent, balancing the humidity of the smoke and avoiding oral irritation caused by excessively dry smoke. The combined use of these three ingredients can make the sensory quality of the heated cigarettes superior.
[0025] Preferably, the heated cigarette is used in conjunction with a laser-heated cigarette device.
[0026] Preferably, the structure of the laser-heated smoking device includes a charging port, a battery compartment, laser components, a positioning lens, replaceable cartridges, an air intake channel, and a magnetic chuck.
[0027] Preferably, the heating device heats the cigarettes using laser positioning.
[0028] Preferably, the method of use includes: placing the rectangular tobacco stick in the smoking device, and using laser positioning to target the upper surface of the rectangular stick 1-2 mm each time during inhalation. 2 The area is heated, and then the laser heating position is moved 1-2 mm, heating the adjacent 1-2 mm area.2 The surface.
[0029] All the specific point values within the above range can be selected, and will not be elaborated on here.
[0030] Compared with the prior art, the present invention has the following beneficial effects: (1) This invention uses an extruder to extrude tobacco raw materials and atomizing agents into a heated cigarette. The heated cigarette is placed in a smoking device. When the consumer smokes, the heating area is precisely controlled, and the smoke generated after heating enters the consumer's mouth. Each heating area can satisfy at least two puffs. As the consumer continues to smoke, the heating position moves backward to heat another section of the cigarette stick. This process continues as the consumer smokes, allowing for multiple puffs. Compared to conventional heated cigarettes where each cigarette can only be smoked 12 times, the heated cigarette of this invention avoids the problems of frequent cartridge replacement and poor smoking uniformity.
[0031] (2) Consumers of the heated cigarette of the present invention do not need to carry a smoking device and a cigarette cartridge at the same time. They can smoke at least 100 puffs at a time, and the heated cigarette can be stopped at any time without preheating.
[0032] (3) The heated cigarette of the present invention, through specific formulations, such as the selection of smoke-generating agents, flavorings and adhesives, can have the advantages of sufficient smoke volume, good taste, strong aroma, low irritation and low impurities, while satisfying the requirement of multiple smokings. Consumers have an excellent sensory experience after using it. Detailed Implementation

[0046] Comparative Example 1 This comparative example provides a reusable heated cigarette, which differs from Example 1 only in that the density of the cigarette stick is 3 g / cm³. 3 Other structures remain the same as in Example 1, and the preparation method is the same as in Example 1.
[0047] Comparative Example 2 This comparative example provides a reusable heated cigarette, which differs from Example 1 only in that the density of the cigarette stick is 15 g / cm³. 3 Other structures remain the same as in Example 1, and the preparation method is the same as in Example 1.
[0048] Comparative Example 3 This comparative example provides a heated cigarette, which differs from Example 1 only in the preparation method. The preparation method is as follows: tobacco raw materials, atomizing agent, tobacco flavoring and adhesive are mixed and spread evenly on a coating machine, and then baked in a 90°C oven for 20 minutes to obtain conventional heated cigarette sheets.
[0049] Test Example 1 Number of suctions The heated cigarettes of Examples 1-3 and Comparative Examples 1-3 were placed on a smoking machine in a heated smoking device and inhaled. Each inhalation was performed with a 1mm radius of the upper surface of the cuboid. 2 The area is heated, then the heating position is moved to heat adjacent 1 mm areas. 2 The number of suctions is counted on the surface of the surface using a suction sensor.
[0050] The results are shown in Table 1.
[0051] Table 1 As shown in Table 1, compared with the conventional heated cigarettes of Comparative Example 3, the heated cigarettes prepared in Examples 1-3 of the present invention can be smoked more than 150 times, which can better solve the problem of frequent cartridge replacement. Moreover, since it is the same heated cigarette, the smoking uniformity of the heated cigarette is also better.
[0052] As shown in Comparative Example 1, when the density of the heated cigarette is too low, the number of puffs decreases significantly. Conversely, when the density is too high, the increase in the number of puffs is not significant, but the production cost increases. Therefore, only when the density of the heated cigarette is within the range defined by this invention can the number of puffs be increased while the process cost is more moderate.
[0053] Test Example 2 Sensory Quality The sensory qualities of the heated cigarettes provided in Examples 1-12 and Comparative Examples 1-3 were tested.
[0054] Test method: Refer to national standard GB 5606.4-2005 Cigarettes Part 4: Sensory technical requirements.
[0055] Test standards: The scoring range for smoke volume is 1-20 points, the scoring range for harmony is 1-20 points, the scoring range for impurities is 1-20 points, the scoring range for irritation is 1-20 points, the scoring range for consistency is 1-20 points, and the total score is 100 points.
[0056] The results are shown in Table 2.
[0057] Table 2 As can be seen from Table 2, compared with heated cigarettes obtained by conventional methods, the heated cigarettes provided in Examples 1-3 of the present invention, through specific formulations, do not show a decrease in smoke volume, harmony, or smoke consistency, and also have lower levels of impurities and irritation.
[0058] As can be seen from the comparison between Examples 1 and Examples 4-6, only when glycerin, propylene glycol and xylitol are used together as the atomizing agent can the amount of smoke released by the cigarette product under heating be guaranteed, thereby promoting the release of aroma substances and improving the sensory smoking quality. As can be seen from the comparison between Examples 1 and Examples 7-9, the combination of sodium alginate, sodium carboxymethyl cellulose and xanthan gum can enhance the overall structural strength. In addition, the combination of the other three can make the sensory quality of heated cigarettes better. As can be seen from the comparison between Examples 1 and Examples 10-12, the tobacco flavoring can only be better paired with the tobacco of the present invention when it is a specific combination of the present invention, thereby making the harmony and consistency better.
