Description

TECHNICAL FIELD

[0001] The present invention relates to the technical field of heat-not-burning cigarettes, in particular to an aerosol generating product suitable for heaters with different lengths.

BACKGROUND

[0002] With consumers' focus on the health issue and increasing demands for personalized experience in cigarette products, the tobacco industry has developed various smoking products with reduced tar and harm in continuous response to consumer demand upgrading. A heated cigarette is capable of providing healthier smoking experience while meeting consumers' sensory needs for cigarette products due to its different cigarette heating mode from a conventional cigarette product.

[0003] An existing integrated aerosol generating product includes an outer pipe and an aerosol generating matrix and other function units with cooling, fragrance enhancing or smoke producing functions which are filled in the outer pipe. Due to limit of a tobacco material, the tobacco material close to a heater is heated fully and generates smoke more easily during smoking, in order to guarantee that a tobacco stick is heated uniformly and completely, an existing aerosol generating product usually needs to match with a heater with an axial length which is consistent with the tobacco stick, so it can be guaranteed that the tobacco stick in any axial height can receive heat of the heater, but this case directly limits an axial length of the tobacco stick in a cigarette. For the purpose of increasing smoke volume and improving original fragrance of tobacco, some researchers arrange a tobacco sheet on the downstream of a tobacco section and tries to elute the tobacco sheet on the downstream through hot smoke generated by the tobacco section, so that smoke in the tobacco sheet is released. However, the present invention discovers that the method is only an ideal state, actually, arranging the tobacco sheet on the downstream of the tobacco section will decrease the smoke volume and reduce fragrance quality instead of increasing the smoke volume and improving the original fragrance of the tobacco. The reason is that the tobacco sheet can generate the smoke only in a case of direct heating, the tobacco sheet can hardly release the smoke only through afterheat of the tobacco section, or say, the smoke generated by the tobacco sheet at this moment is very little, and the smoke is held back by the added tobacco sheet instead, which leads to decrease of the smoke volume, namely, in this case, the tobacco sheet is mainly a material for holding back the smoke, which is totally unexpected by the present invention. Therefore, to design an aerosol generating product which can release smoke only through smoke afterheat to increase the smoke volume is what people want.

[0004] The aerosol generating matrix of the existing integrated aerosol generating product is usually formed by mixing tobacco powder or tobacco particles with a smoke producing agent and an adhesive to form a pulp, then obtaining a cigarette core long strip in an extruding or molding mode and then cutting the same into a plurality of cigarette core sticks. A problem lies in that in order to guarantee that a cigarette core stick at a cutting position does not deform and collapse during cutting, the cigarette core stick needs to have a certain hardness, but too hard cigarette core stick leads to too brittle cigarette core stick, and breaking is prone to occurring in a filling, packing or using process, and thus, there is a dilemma that cutting is not easy in the case of too small hardness and breaking is prone to occurring in the case of too large hardness. Besides, the tobacco powder or the tobacco particles of a smoking material need(s) a large quantity of adhesive in a forming process, and the adhesive becomes hard after being solidified, which is the reason why the entire cigarette core stick is too hard.

[0005] Therefore, how to develop a new heated cigarette fragrance enhancing mode, solve the problem that the integrated aerosol generating matrix stick is too hard and guarantee that no collapse and deformation occur at the cutting position is expected by people to solve.

[0006] The present invention is provided for solving the above problems.

SUMMARY

[0007] The present invention provides an aerosol generating product suitable for heaters with different lengths, including a smoke producing pipe; and the smoke producing pipe includes a tobacco substance and/or a porous material, a fragrance enhancing substance and/or a smoke producing substance, a supporting fiber and an adhesive; and
an aerosol generating apparatus matching with the aerosol generating product has a heater, and an axial length of the heater is less than or equal to an axial length of the smoke producing pipe.

[0008] Preferably, the smoke producing pipe has a length ranging from 10 mm to 25 mm.

[0009] Preferably, the tobacco substance includes tobacco powder or tobacco particles.

[0010] Preferably, the porous material includes activated carbon, a ceramic molecular sieve type inorganic material, or a polymer type organic material, or a plant natural porous material.

[0011] Preferably, the fragrance enhancing substance includes menthol, ionone, ethyl maltol, vanillin, rose absolute essence and flavor or a tobacco extract or nicotine salt; and the smoke producing substance includes one or more of glycerol or propylene glycol.

[0012] Preferably, a pipe wall of the smoke producing pipe has a thickness ranging from 0.8 mm to 1.5 mm.

[0013] Preferably, the supporting fiber is selected from a plant fiber, the plant fiber includes one or more of a fluff pulp fiber, a jute pulp fiber or a wood pulp fiber which are commonly used in the art, and the wood pulp fiber may be selected from commonly used wood pulp fibers such as birch wood, poplar wood, and pine wood.

[0014] Preferably, in the case that the smoke producing pipe includes the tobacco substance and the porous material, a mass ratio of the tobacco substance to the porous material is in a range from 0.1 to 0.5.

[0015] Preferably, a structure of the smoke producing pipe is a pipe body with one or more axial airflow passages. In the case that the smoke producing pipe is an ordinary hollow pipe body, the smoke producing pipe has one axial airflow passage, and in the case that the hollow pipe body internally has a structure with a "cross-shaped" or "Y-shaped" section, the smoke producing pipe has a plurality of axial airflow passages.

[0016] A second aspect of the present invention provides a preparation method for the aerosol generating product described in the first aspect of the present invention. The preparation method for the smoke producing pipe includes the following steps:

(1) adsorbing a fragrance enhancing substance and/or a smoke producing substance to a tobacco substance and/or a porous material first;

(2) mixing the tobacco substance and/or the porous material with the fragrance enhancing substance and/or the smoke producing substance adsorbed thereto with a supporting fiber, then adding an adhesive into a mixture, and obtaining a mixed pulp after mixing; and

(3) obtaining a smoke producing pipe and/or a filter pipe by forming the mixed pulp in an extruding or molding mode.

[0017] Preferably, in step (1), the porous material is powdery with 80 meshes to 500 meshes, where a load quantity of the fragrance enhancing substance and/or the smoke producing substance is 40% to 80% of a total weight of the porous material and/or the tobacco substance; in step (2), the adhesive includes a water-soluble adhesive, and the supporting fiber mixed with the tobacco substance and/or the porous material has a length ranging from 0.5 mm to 5 mm.

[0018] A length of a plant fiber added into the smoke producing pipe or the filter pipe rather than a length of a plant fiber raw material is limited here. This is because for the purpose of convenient storage and transportation, at present, a plant fiber used in the market is usually agglomerated, a defibering process is needed during use, that is, the agglomerated plant fiber needs to be loosened. This process may adopt the following two methods: one method is to soak the agglomerated plant fiber in water till the plant fiber is separated, then perform wet milling till a needed fiber length is obtained, and at the moment, perform dewatering treatment on the separated plant fiber again, because the plant fiber mixed with the porous material and/or the tobacco substance cannot contain too much water. The other method is to perform dry milling on the agglomerated plant fiber directly till a needed fiber length is obtained, and then mix the fiber with the porous material and/or the tobacco substance.

[0019] Preferably, in the smoke producing pipe, the added amount of the supporting fiber is 5% to 10% of a total mass of the mixed pulp, and the added amount of the adhesive is 50% to 70% of the total mass of the mixed pulp.

[0020] The aerosol generating product composed of a cigarette core stick according to the present invention is especially suitable for circumferential heating, airflow heating and other heating modes except central heating, this is because as for an existing cigarette core stick with a central passage for central heating, a volume of the cigarette core stick is reduced and internally shrunk after being heated due to flowing away of a smoke producing agent and the like, resulting in that after smoking, the cigarette core stick is stuck to a heating stick, and is difficult to clean. The present invention is aware of this problem, and applies the cigarette core stick to a heated cigarette in circumferential heating, airflow heating and other heating modes except central heating.

[0021] Compared with the prior art, the present invention has the following beneficial effects.

1. The aerosol generating product of the present invention is suitable for the heaters with different lengths though the axial length of the heater is less than or equal to the axial length of the smoke producing pipe. This is because the smoke producing pipe and/or the filter pipe of the present invention uses the tobacco substance and/or the porous material as a main body, the fragrance enhancing substance and/or the smoke producing substance is adsorbed by the tobacco substance and/or the porous material to achieve a fragrance enhancing or smoke producing effect. As the fragrance enhancing substance and/or the smoke producing substance are/is only adsorbed to the porous material, the fragrance enhancing substance and/or the smoke producing substance in the cigarette core stick in a region not covered with the heater can be released only through heat conducted by hot smoke, and thus the effects of fragrance enhancing and increasing the smoke volume are achieved.

2. The smoke producing pipe is integrated, so cigarette paper may be omitted, all units are directly combined together through forming paper or filled in a paper bobbin together, and thus the production efficiency is improved. Distinctively, the smoke producing pipe and a binary combination filter stick may be directly twisted and combined through tipping paper to form a cigarette, in this way, a cigarette structure can be simplified, and the production efficiency can be improved.

3. A fragrance enhancing mode of adsorbing the fragrance enhancing substance to the porous material widens a selection range and form of the fragrance enhancing substance, and any fragrance enhancing substance capable of being adsorbed into the porous material is fine, not limited to breakable capsule fragrance enhancing. In addition, the fragrance enhancing substance is adsorbed into the porous material, so the fragrance enhancing substance in the porous material is released slowly during smoking, and this type of fragrance enhancing can slowly release the fragrance enhancing substance and guarantee consistent fragrance quality before and after smoking. Further, based on this, both the fragrance enhancing substance and the smoke producing substance may be added to a filter section, and the smoke producing substance in the filter section can supplement the smoke volume at a later stage of smoking.
The tobacco powder or the tobacco particles has/have a pore structure and can adsorb the fragrance enhancing substance and the smoke producing substance itself, so as to increase the smoke volume and supplement the smoke fragrance, and as a temperature of a smoke producing section is high, releasing of the fragrance enhancing substance is more facilitated by introducing the fragrance enhancing substance into the smoke producing section, and thus the fragrance enhancing effect is improved. In addition, different fragrance enhancing substances may achieve characteristic flavor smoke of different fragrance types, and adding the fragrance enhancing substance and the smoke producing substance to the smoke producing section can make the characteristic flavor and the smoke be mixed more uniformly and make fragrance coordination better.

4. The smoke producing pipe of the present invention uses the supporting fiber as a forming accessory, and adding of the supporting fiber has the following benefits: (1) a sugar content of the supporting fiber is high, the added supporting fiber can play a role in bonding the porous material, so that a use amount of the adhesive is reduced, and not only is bonding the porous material into a stick guaranteed, but also the problem that the filter pipe becomes hard and brittle after the adhesive is solidified is solved. (2) The supporting fiber can play a role in supporting the filter pipe, so that collapse and deformation are prevented when a porous material fragrance enhancing long strip is cut into the smoke producing pipe. (3) The supporting fiber is odourless without an influence on the smoke during smoking.

5. The structure of the smoke producing pipe of the present invention is the pipe body with one or more axial airflow passages. As for the existing cigarette core stick, in order to increase a flowing area of the smoke, a groove is usually formed in the periphery as an axial passage, but the present invention discovers that when a combination machine combines the cigarette core stick and other units, a roller of the combination machine picks up the cigarette core stick through a suction force, and a contact area between a suction opening of the roller and the cigarette core stick is too small due to the groove in the periphery, making it difficult to suck and often causing a problem of falling.. Therefore, a structure a cigarette core section of the present invention is in a round pipe shape with a plurality of axial passages in a center, there is no axial groove in the periphery, so that the contact area between the suction opening of the roller and the cigarette core stick is increased, and it is guaranteed that the suction opening of the roller can suck up the cigarette core stick more stably.

6. A porous material function stick of the present invention has a high adsorption amount for both the fragrance enhancing substance and the smoke producing substance, so its fragrance carrying capacity is higher than that of a reconstituted tobacco leaf sheet or acetate fiber tows.
