Description

An aerosol generating product applicable to heaters of different lengths Technical Field

[0001] The present invention relates to the technical field of heat-not-burn cigarettes, and in particular to an aerosol generating product applicable to heaters of different lengths. Background Art

[0002] As consumers prioritize health and demand a personalized experience with cigarettes, the tobacco industry is continuously responding to these evolving needs by developing a variety of smoking products with reduced tar content and harm reduction. Heat-treated cigarettes, by contrast, differ from traditional cigarettes in their heating method, enabling them to satisfy consumers' sensory needs while providing a healthier smoking experience.

[0003] Existing integrated aerosol generating products include an outer tube and an aerosol generating matrix filled in the outer tube, as well as other functional units with cooling, flavoring or smoking functions. Due to the limitations of the tobacco material itself, only the tobacco material close to the heater is fully heated during inhalation and is more likely to produce smoke. In order to ensure that the tobacco rod is heated evenly and comprehensively, existing aerosol generating products generally need to be adapted to a heater with an axial length consistent with the tobacco rod, so as to ensure that tobacco rods of any axial height can receive the heat of the heater. However, this situation directly limits the axial length of the tobacco rod in the cigarette. In order to increase the amount of smoke and increase the original aroma of tobacco, some researchers have set tobacco sheets downstream of the tobacco section, attempting to elute the downstream tobacco sheets with the hot smoke generated by the tobacco section, thereby releasing the smoke in the tobacco sheets. However, the present invention found that this method is only an ideal state. In fact, setting tobacco sheets downstream of the tobacco section will not only not increase the amount of smoke or improve the original aroma of tobacco, but will reduce the amount of smoke and aroma quality. The reason for this is that tobacco sheets can only generate smoke when directly heated. Using only the residual heat of the tobacco segments makes it difficult to release smoke from the tobacco sheets, or in other words, the smoke generated by the tobacco sheets is negligible. Instead, the addition of the tobacco sheets traps the smoke, thereby reducing the amount of smoke. In other words, the tobacco sheets dominate the role of the smoke trapping material in this case, which is completely unanticipated by the present invention. Therefore, it is desirable to design an aerosol-generating product that can release smoke solely through the residual heat of the smoke, thereby increasing the amount of smoke.

[0004] At present, the aerosol-generating matrix of integrated aerosol-generating products is usually a mixture of tobacco powder or tobacco particles with a smoke-generating agent and a binder into a slurry, which is then extruded or molded to obtain a long strip of tobacco core, and then cut into multiple tobacco core rods. The problem is that in order to ensure that the tobacco core rod at the cut does not deform or collapse during cutting, the tobacco core rod needs to have a certain hardness. However, if the hardness of the tobacco core rod is too high, it will become particularly brittle and prone to breakage during the filling, packaging or use process. Therefore, there is a dilemma: the hardness is too low and it is difficult to cut, while the hardness is too high and it is easy to break. In addition, a large amount of binder is required in the molding process of the smoking material tobacco powder or tobacco particles, and the binder will become hard after curing, which is also the reason why the overall tobacco core rod is too hard.

[0005] Therefore, how to develop a new form of flavoring method for heated cigarettes, and how to solve the problem of the one-piece aerosol generating matrix rod being too hard and ensure that the cutting part does not collapse and deform, are what people hope to solve.

[0006] In order to solve the above problems, the present invention is proposed.

[0007] Summary of the Invention

[0008] The present invention provides an aerosol generating product applicable to heaters of different lengths, comprising a smoking tube; the smoking tube comprises tobacco material and / or porous material, flavoring material and / or smoking material, supporting fibers and adhesive;

[0009] The aerosol generating device matched with the aerosol generating product has a heater, and the axial length of the heater is less than or equal to the axial length of the smoke generating tube.

[0010] Preferably, the length of the smoking tube is 10-25 mm.

[0011] Preferably, the tobacco material comprises tobacco powder or tobacco particles.

[0012] Preferably, the porous material includes activated carbon, ceramic molecular sieve inorganic materials, or polymer organic materials, or plant natural porous materials.

[0013] Preferably, the flavoring substance comprises menthol, ionone, ethyl maltol, vanillin, rose absolute flavor or tobacco extract or nicotine salt;

[0014] The smoking substance includes one or more of glycerol or propylene glycol.

[0015] Preferably, the wall thickness of the smoke tube is 0.8 mm-1.5 mm.

[0016] Preferably, the supporting fibers are selected from plant fibers, which include those commonly used in the art, such as fluff pulp fibers, hemp pulp fibers or wood pulp fibers, wherein the wood pulp fibers can be selected from commonly used wood pulp fibers such as birch, poplar or pine.

[0017] Preferably, when the smoking tube comprises tobacco substance and porous material, the mass ratio of the tobacco substance to the porous material is 0.1-0.5.

[0018] Preferably, the smoke tube has a tube body with one or more axial airflow channels. A conventional hollow tube body has one axial airflow channel, while a hollow tube body with a cross-shaped or Y-shaped cross-section has multiple axial airflow channels.

[0019] A second aspect of the present invention provides a method for preparing the aerosol-generating product according to the first aspect of the present invention, wherein the method for preparing the smoking tube comprises the following steps:

[0020] (1) The tobacco material and / or porous material first absorb the flavoring substance and / or smoke-generating substance;

[0021] (2) mixing the tobacco material and / or porous material after adsorption of the flavoring substance and / or the smoke-generating substance with the supporting fibers, and then adding a binder thereto to obtain a mixed slurry;

[0022] (3) The mixed slurry is formed by extrusion or molding to obtain the smoke tube and / or the filter tube.

[0023] Preferably, in step (1), the porous material is in powder form with a mesh size of 80-500 mesh, wherein the loading amount of the flavoring substance and / or the smoke-generating substance is 40-80% of the total weight of the porous material and / or the tobacco substance; in step (2), the adhesive comprises a water-soluble adhesive, and the supporting fibers mixed with the tobacco substance and / or the porous material have a length of 0.5 mm to 5 mm;

[0024] What is limited here is the length of the plant fiber added to the smoking tube or filter tube, not the length of the plant fiber raw material. This is because in order to facilitate storage and transportation, the plant fibers currently used in the market are usually agglomerated into blocks. When used, a process of defiberization is required, that is, the plant fibers in blocks need to be loosened. This process can be carried out in the following two ways: First, the plant fibers agglomerated into blocks are soaked in water and the plant fibers are loosened, and then wet-grinded until the required fiber length is obtained. At this time, since the plant fibers mixed with porous materials and / or tobacco substances cannot contain a large amount of water, the loosened plant fibers are dehydrated again. Second, the plant fibers agglomerated into blocks are directly dry-grinded until the required fiber length is obtained, and then mixed with porous materials and / or tobacco substances.

[0025] Preferably, in the smoke-generating tube, the added amount of the supporting fibers is 5-10% of the total mass of the mixed slurry, and the added amount of the adhesive is 50-70% of the total mass of the mixed slurry.

[0026] The aerosol-generating product formed from the core rod of the present invention is particularly suitable for heating methods other than central heating, such as circumferential heating and airflow heating. This is because existing core rods with a central channel for central heating shrink and shrink inward after heating due to the loss of smoke-generating agents, which causes the core rod to stick to the heating rod after puffing, making it difficult to clean. The present invention recognizes this problem and utilizes the core rod in heated cigarettes using methods other than central heating, such as circumferential heating and airflow heating.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The aerosol generating product of the present invention can be applied to heaters of different lengths, even if the axial length of the heater is less than or equal to the axial length of the smoke tube. This is because the smoke tube and / or the filter tube of the present invention uses tobacco material and / or porous material as the main body, and the tobacco material and / or porous material adsorb flavoring substances or smoke-generating substances to achieve the effect of flavoring or smoke-generating. Since the flavoring substances and / or smoke-generating substances are only adsorbed on the porous material, the heat transferred by the hot flue gas alone can release the flavoring substances and / or smoke-generating substances in the cigarette core rod in the area not covered by the heater, thereby playing the role of flavoring and increasing the amount of smoke.

[0029] 2. Since the smoke tube is integrally formed, cigarette paper is not required. Each unit can be directly laminated with forming paper or packed into a paper tube, improving production efficiency. In particular, the smoke tube can be directly combined with a two-component composite filter stick using tipping paper to form a cigarette, simplifying the cigarette structure and improving production efficiency.

[0030] 3. The flavoring method of porous material adsorbing flavoring substances expands the range and form of flavoring substances. It is not limited to flavoring through popping beads. As long as the flavoring substance can be adsorbed into the interior of the porous material, it can be used. In addition, because the flavoring substance is adsorbed into the interior of the porous material, the flavoring substance in the porous material is also slowly released during the puffing process. This form of flavoring can achieve a sustained release of the flavoring substance, ensuring the consistency of the aroma quality before and after puffing. Furthermore, on this basis, flavoring substances and smoking substances can be added simultaneously to the filter segment. The smoking substance in the filter segment can supplement the smoke volume in the later stage of puffing.

[0031] Tobacco powder or particles have a porous structure that allows them to absorb flavoring and smoking substances, thereby increasing smoke volume and flavoring. Since the temperature of the smoking section is higher, introducing flavoring substances into the smoking section facilitates their release, thereby enhancing the flavoring effect. Furthermore, different flavoring substances can produce distinct flavors in smoke. Adding flavoring and smoking substances to the smoking section allows for a more even blend of the characteristic flavor and smoke, resulting in a better aroma balance.

[0032] 4. The smoke tube of the present invention uses support fibers as a molding auxiliary material. The addition of support fibers has the following advantages: (1) The support fibers themselves have a high sugar content. Their addition can produce a bonding effect on the porous material, thereby reducing the amount of adhesive used. This not only ensures that the porous material is bonded into a rod, but also solves the problem of the filter tube becoming hard and brittle after the adhesive is cured. (2) The support fibers can support the filter tube, preventing it from collapsing and deforming when the porous material flavoring strip is cut into a smoke tube. (3) The support fibers are odorless and will not affect the smoke when inhaled.

[0033] 5. The structure of the smoke tube of the present invention is a tube body with one or more axial airflow channels. In order to increase the flow area of ​​smoke, existing cigarette core rods usually have grooves on the outer periphery as axial channels. However, the present invention found that when the compounding machine combines the cigarette core rod with other units, the roller of the compounding machine picks up the cigarette core rod by suction. Due to the grooves on the outer periphery, the contact area between the roller's suction port and the cigarette core rod is too small, making it difficult to suck it, and the problem of it falling often occurs. Therefore, the cigarette core segment structure of the present invention is a circular tube with multiple axial channels in the center, and its outer periphery is not provided with axial grooves, thereby increasing the contact area between the roller's suction port and the cigarette core rod, ensuring that the roller's suction port can more stably suck the cigarette core rod.

[0034] 6. The porous material functional rod of the present invention has a high adsorption capacity for both flavoring substances and smoke-generating substances, so its flavor-carrying capacity is higher than that of reconstituted tobacco leaves or acetate fiber bundles.

[0050] As shown in Figure 1 , the aerosol-generating article of this embodiment comprises, from upstream to downstream, a smoke-generating section 1, a hollow tube section 2, and an acetate filter section 3. The smoke-generating section 1 is a smoke-generating tube. The hollow tube section 2 is a hollow acetate tube with ventilation holes 5 extending through the outer tube and the hollow tube wall. In other embodiments, the hollow tube section 2 can also be a hollow paper tube. The lengths of the smoke-generating section 1, hollow tube section 2, and acetate filter section 3 are 25 mm, 10 mm, and 10 mm, respectively.

[0051] The smoking tube as the smoking section 1 comprises tobacco material, flavoring material and smoking material, supporting fibers and a binder.

[0052] The tobacco material includes tobacco powder.

[0053] The flavoring substance includes menthol.

[0054] The smoking substances include glycerin and propylene glycol.

[0055] The support fibers are selected from fluff pulp fibers.

[0056] The added amount of the supporting fibers is 5% of the total mass of the mixed slurry, and the added amount of the adhesive is 50% of the total mass of the mixed slurry.

[0057] The structure of the smoke tube is an empty tube with one axial airflow channel 4. In addition, the interior of the empty tube also has a supporting structure, and accordingly it can also have 2-4 axial airflow channels 4, see Figures 3-7.

[0058] The method for preparing the smoke tube comprises the following steps:

[0059] (1) Tobacco substances first adsorb flavoring substances and smoke-generating substances;

[0060] (2) mixing the tobacco material after the flavoring substance and the smoke-generating substance are adsorbed with plant fibers, and then adding a binder thereto to obtain a mixed slurry;

[0061] (3) The mixed slurry is formed by extrusion or molding to obtain the porous material functional rod.

[0062] In step (1), the loading amount of the flavoring substance and the smoke-generating substance is 60% of the weight of the tobacco substance. In step (2), the adhesive comprises a water-soluble adhesive, and the plant fiber mixed with the tobacco substance has a length of 0.5 mm to 5 mm.

[0063] To put it more simply, the main body of the smoke-generating tube serving as the smoke-generating section 1 is smoke powder.

The supporting fibers are added at a concentration of 8% by weight of the mixed slurry, and the binder is added at a concentration of 60% by weight of the mixed slurry.

[0066] That is to say, the main body of the smoking tube serving as the smoking section 1 in the aerosol generating product of this embodiment is activated carbon. At this time, since the smoking section does not contain tobacco substances, in order to provide the original tobacco aroma, the flavoring substance adsorbed in the smoking tube is tobacco extract.

[0068] The aerosol-generating article of this embodiment has the same structure as that of Example 1, except that the smoke-generating tube, serving as the smoke-generating section 1, comprises a tobacco material, a porous material, a flavoring agent and a smoke-generating agent, supporting fibers, and a binder. The porous material comprises activated carbon, which is in a powdered form with a mesh size of 80-500. The flavoring agent and smoke-generating agent are loaded at a concentration of 60% by weight of the porous material and tobacco material. The supporting fibers are added at a concentration of 8% by weight of the total mixed slurry, and the binder is added at a concentration of 60% by weight of the total mixed slurry.

The lengths of the smoke-generating segment 1, support segment 6, hollow tube segment 2, and acetate filter segment 3 are 25 mm, 10 mm, 10 mm, and 10 mm, respectively.

[0073] The smoking section 1 is a smoking tube, and the supporting section 6 is a porous material rod. The porous material rod comprises a porous material, a flavoring substance and a smoking substance, supporting fibers, and a binder. The porous material comprises activated carbon, which is in powder form and has a mesh size of 80-500. The flavoring substance and smoking substance are loaded at a weight of 60% of the porous material.

[0074] More simply, the main component of the smoke tube in smoke-generating segment 1 is smoke powder, while the main component of the porous material rod in support segment 6 is activated carbon.

The support fiber in support segment 6 is added in an amount of 8% of the total mass of the mixed slurry, and the binder is added in an amount of 60% of the total mass of the mixed slurry.

[0075] Example 5

[0076] The aerosol generating product of this embodiment has the same structure as that of embodiment 4, except that the support section 6 in the aerosol generating product of this embodiment is a mixed rod of tobacco material and porous material, and the mixed rod of tobacco material and porous material includes tobacco material, porous material, flavoring material and smoke-generating material, support fiber and adhesive. The loading amount of flavoring material and smoke-generating material is 60% of the total weight of the porous material and tobacco material. The amount of support fiber added in the smoke-generating section 1 is 5% of the total mass of the mixed slurry, and the amount of adhesive added is 50% of the total mass of the mixed slurry. The amount of support fiber added in the support section 6 is 8% of the total mass of the mixed slurry, and the amount of adhesive added is 60% of the total mass of the mixed slurry.

The amount of the supporting fibers added in the supporting section 6 is 8% of the total mass of the mixed slurry, and the amount of the adhesive added is 60% of the total mass of the mixed slurry.

[0081] In other words, the main component of the smoke-generating tube, which serves as the smoking segment 1 in the aerosol-generating article of this embodiment, is activated carbon. Since the smoking segment does not contain tobacco, the flavoring substance adsorbed in the smoke-generating tube is tobacco extract to provide the original tobacco aroma.
