Description
Technical Field
The invention relates to the field of heating non-burning cigarettes, in particular to a fragrance slow-release cooling unit and a heating type aerosol generating product comprising the same.
Background
At the beginning of the development of the heat-not-burn product, the smoking material is mainly formed by coating tobacco materials on a tobacco sheet or a paper substrate, with the development of the heat-not-burn technology, particle type smoking materials gradually appear, but because particles are easy to drop in the preparation process of a cartridge, the particle type smoking part is often required to be separated from adjacent fasteners by fasteners. For example, patent CN 108078012A discloses a heating non-combustible tobacco product containing tobacco particles, the particles are caught by a sleeve, and a top cover, a particle end and a base which are sequentially arranged in the sleeve, the particle section is formed by filling tobacco particles between the top cover and the base, and the top cover is provided with a top vent hole. CN 207885652U discloses a cigarette filter cooling mouth, discloses the filter element that is provided with the through-hole, and the function of this filter element is to let the filter material can't pass through the through-hole. CN 109770422A discloses a cooling composite filter stick and a manufacturing process thereof, wherein a fixing piece plays a blocking role between a cooling material and smoke particles, the fixing piece is wrapped on the inner wall of a circular tube, and at least one air channel for backflow smoke is formed at the joint of the fixing piece and the inner wall of the circular tube. CN 109105951A discloses a cigarette capable of reducing smoke temperature, a filter disc is provided with a plurality of through holes for conducting smoke generated by smoke particles. As can be seen from the above patent, the part of the fixing part used for blocking the falling of the particles in the prior art only plays the roles of blocking the falling of the particles and ventilating and guiding the flow, and the purpose is single.
On the other hand, most of spacer units used for low-temperature heating non-combustible products on the market are made of organic high polymer materials, and because the spacer units are close to the fuming particles and the heating plate, the spacer units are softened and deformed under the action of high temperature, harmful substances can be released, and certain potential safety hazards exist.
In addition, the smoke temperature after being filtered by the filter tip is distributed at 45-90 ℃, in order to reduce the smoke temperature entering the mouth of a smoker, the cigarette structure of the heating non-combustion cigarette products on the market has a temperature reduction section to reduce the smoke temperature and improve the smoking comfort, but the smoke is reduced in temperature and the aroma is lost at the same time due to the addition of the temperature reduction section, so that the sensory smoking quality of the product is further influenced.
The present invention has been made to solve the above problems.
Disclosure of Invention

Preferably, the end face of the cooling unit is also provided with a groove 43. The purpose of the grooves 43 is to: when the aerosol generated by heating the heating aerosol generating product flows through the cooling unit, the grooves can effectively gather the aerosol to flow through the airflow channel 42, so that the aerosol is prevented or reduced from flowing through other areas outside the airflow channel, the aerosol can flow through the main channel to the maximum extent, and the loss of aroma components in the aerosol is reduced.
Preferably, the cooling unit body 41 is a porous inorganic material or a porous plant material, the porous inorganic material is selected from one or more of alumina, silicon carbide, silicon nitride, aluminum nitride and diatomite, the porous plant material is a natural wood material selected from bamboo or rattan, the bamboo is such as moso bamboo, and the rattan is such as sargentgloryvine stem.
Preferably, the flavor component is a spice selected from one or more of coffee essence, mint essence, blueberry essence, strawberry essence, dried orange peel essence, damascenone, phenethyl alcohol, amyl acetate, ionone, neophytadiene, hami melon essence, eugenol, amyl valerate, cinnamaldehyde, cinnamic acid cassia ester, ethyl phenylacetate, perillartine, 2-methyl hexyl butyrate, furanone acetate, phenethyl phenylacetate, ethyl heptanoate, plum extract, myricetin aldehyde, 2-methyl butyric acid, lemon oil, 2-ethyl furan, ethyl cucurbitacin, farnesyl acetone, sclareolide, benzyl propionate or vetiver oil, and is used for improving smoke suction quality.
In the fragrance slow-release cooling unit of the invention, the fragrance component not only refers to the above-mentioned perfume, but also includes the case that the porous plant material carries the fragrance component, for example, when moso bamboo is used as the raw material of the cooling unit main body 41, the fragrance component can be natural bamboo fragrance carried by the moso bamboo raw material, at this time, the fragrance slow-release cooling unit can be used as a blocking component (spacer) of a granular aerosol generating material or a paste aerosol generating material of an aerosol generating product, namely, the fragrance slow-release cooling unit can play a role in blocking and can further compensate fragrance loss caused by aerosol cooling.
Preferably, the flavor component is wrapped by a flavor-locking substance, and the flavor-locking substance is selected from phase-change materials such as konjac gum, chitosan, shellac, guar gum, gelatin, sodium alginate, carrageenan, pectin, acacia, agar or polyethylene glycol.
The preparation method of the cooling unit comprises the following steps: (1) firstly, forming a porous inorganic material and a porous natural wood material into a fixed size and shape by a grinding tool, wherein the diameter of the porous inorganic material and the porous natural wood material is equal to the inner diameter of an outer tube 1 of a heating non-combustible product, and sterilizing and disinfecting the cooling unit; (2) loading the fragrance substance, wherein the step is divided into two cases, namely the fragrance component in the cooling unit is a perfume, and the perfume loading is completed by adopting the following step a; in the second case, the fragrance component in the cooling unit is a perfume, and the fragrance component is wrapped by a perfume-locking substance, and the loading of the mixture of the perfume and the perfume-locking substance is completed by the following b step; the method specifically comprises the following steps: a. loading of the spice: dripping the target perfume on the cooling unit or soaking the cooling unit body in the target perfume; b. loading of the mixture of perfume and perfume-locking substance: firstly, heating a fragrance locking substance (the heating temperature depends on the phase transition temperature of the fragrance locking substance) to change the fragrance locking substance into a flowing state, then uniformly mixing a target fragrance with the flowing fragrance locking substance according to a certain proportion to obtain a mixed solution of the fragrance and the fragrance locking substance, and then dropwise adding the mixed solution of the flowing fragrance and the fragrance locking substance on the cooling unit or soaking the main body of the cooling unit in the mixed solution of the flowing fragrance and the fragrance locking substance; (3) after loading the spice or the mixture of the spice and the spice-locking substance, cooling and drying the cooling unit, and finally preparing the cooling unit with the fragrance slow-release function, which is suitable for heating non-combustible products.
Because the cooling unit body 41 is formed by porous inorganic material and porous natural wood material through a grinding tool, the cooling unit body 41 has the characteristic of being porous, the cooling unit body 41 is soaked in spice or the spice is dripped on the cooling unit body 41, the cooling unit body 41 can effectively adsorb the spice, the aroma component is promoted to be released through heat when smoke flows through, the aroma loss caused by the cooling unit when the temperature of the smoke is reduced can be compensated, further, compared with the condition that polylactic acid and other materials are used as the cooling unit main body material and then spice substances are directly coated on the surface of the cooling unit, the porous characteristic of the cooling unit body 41 ensures that the adsorbed spice amount is larger, the spice substances are uniformly distributed, partial spice substances are adsorbed in the cooling unit main body, the aroma is uniformly released, the retention time is long, and the phenomenon that the aroma is not uniformly released and the aroma is not directly coated is avoided, Short aroma retention time, strong aroma in the early stage of smoking, and weak aroma in the later stage of smoking.
Furthermore, the pore channels of the cooling unit body 41 of the present invention can also adsorb aroma-locking substances with phase-change function, and the aroma-locking substances undergo phase change along with the change of the temperature of the non-combustible cigarette during the smoking process of the non-combustible cigarette, so that the volatile components with low boiling point in the aroma in the cooling unit body 41 are uniformly and slowly released during the smoking process.
In a second aspect, the invention provides a heated aerosol-generating article incorporating the cooling unit, comprising an outer tube 1 and, located within the outer tube and arranged in that order, an aerosol-generating material unit 3, a cooling unit 4 and a filter unit 6. The cooling unit 4 is the fragrance slow-release cooling unit according to the first aspect of the invention.
Preferably, the heated aerosol-generating article further comprises a sealing film 2, the sealing film 2 being located at an end face of the outer tube 1 on the side closer to the unit of aerosol-generating material 3.
Preferably, the heated aerosol-generating article further comprises an end cavity 8, the end cavity 8 being located on a side remote from the unit of aerosol-generating material 3, the end cavity 8 being defined by the outer tube 1. While some smokers may be unsafe because of direct contact with the filter material of the cigarette filter tip during smoking, the end cavity 8 of the heated aerosol generating article of the present invention is designed to contact only the outer tube 1 at the mouth of the smoker and not the filter material, thereby eliminating some of the above-mentioned problems of the smoker, and because the heated aerosol generating device of the present invention is integrally formed, and the aerosol generating material unit 3, the cooling unit 4 and the filter unit 6 are sequentially inserted into the outer tube 1, the heated aerosol generating article with a filter tip cavity can be simply and easily prepared.
Preferably, an aroma-increasing particle unit 7 and a cavity unit 5 are arranged between the cooling unit 4 and the filter tip unit 6, so as to further reduce the smoke temperature and supplement aroma.
Preferably, the aerosol generating material is in the form of particles or a paste, and when in particulate form, the airflow passage (42) has a diameter less than the diameter of an individual particle, that is the airflow passage 42 does not allow passage of particulate aerosol generating material. The granular aerosol generating material and the pasty aerosol generating material can be prepared by the common preparation method in the prior art, the prepared granular aerosol generating material and the pasty aerosol generating material are both suitable for the invention, more specifically, the preparation of the granular aerosol generating material can refer to the patent (application number: 201811285170.3; patent name: a material of cigarette smoke particles which can not be combusted by heating and the preparation method thereof), and the preparation of the pasty aerosol generating material can refer to the patent (application number: 201910245932.5; patent name: a cigarette cartridge which can not be combusted by heating and the preparation thereof).
When the aerosol-generating material unit 3 of the heated aerosol-generating product is a pasty aerosol-generating material, the sealing film 2 is not essential, but the addition of the sealing film 2 can further prevent the pasty aerosol-generating material in the aerosol-generating material unit 3 from dropping into the heated non-combustible cigarette smoking set when the heated aerosol-generating device is taken out of the heated smoking set after the smoking process is completed, and the structure of the cooling unit 4 can also prevent the pasty aerosol-generating material in the aerosol-generating material unit 3 from being pushed when the heated aerosol-generating product is inserted into the heated non-combustible cigarette smoking set. When the aerosol-generating material unit 3 of the heating aerosol-generating device is a particulate aerosol-generating material, the sealing film 2 is necessary, the sealing film 2 can prevent the particulate aerosol-generating material from falling into the external environment, and the cooling unit 4 has its own structure, and since the diameter of the air flow passage is smaller than the diameter of a single particle of the particulate aerosol-generating material, that is, the air flow passage 42 does not allow the particulate aerosol-generating material to pass through, the cooling unit 4 can be used as a blocking member for the particulate aerosol-generating material, and can prevent the particulate aerosol-generating material from falling into other units of the heating aerosol-generating product.
Compared with the prior art, the invention has the following beneficial effects:
1. the cooling unit body 41 of the present invention has a porous characteristic, preferably, the cooling unit body 41 is formed by a porous inorganic material or a porous natural wood material through a grinding tool, and the porous inorganic material or the porous natural wood material is soaked in the perfume or the perfume is dripped on the cooling unit body 41, the cooling unit body 41 can effectively adsorb the perfume, the release of the aroma components is promoted by heat when the smoke flows through, and the loss of the perfume caused by the cooling unit when the smoke temperature is reduced can be compensated, further, compared with the situation that polylactic acid, plastic and other materials are used as the cooling unit main body material and then the perfume material is directly coated on the surface of the cooling unit, the porous characteristic of the cooling unit body 41 of the present invention enables the adsorbed perfume amount to be larger, the perfume material to be uniformly distributed, and part of the perfume material to be adsorbed in the cooling unit main body, the release is uniform, and, the problems of uneven fragrance release, short fragrance retention time, strong fragrance in the early stage of smoking and over-light fragrance in the later stage of smoking caused by direct coating are avoided.
2. The microcosmic porous structure and the macroscopic airflow channel of the cooling unit body 41 of the invention well increase the contact area with the smoke, greatly improve the cooling effect of the smoke, and simultaneously, the airflow channel 42 is a spiral or columnar macroscopic flute structure when hot air flows through, greatly increase the contact area of the airflow and the aroma components, improve the release amount of the aroma components, and simultaneously, the aroma components are continuously released through the continuous hot airflow.
3. In a preferred embodiment of the present invention, an aroma-locking substance with a phase change function may be further adsorbed inside the pore channel of the cooling unit body 41 of the present invention, and in a smoking process of a heated non-combusted cigarette, the aroma-locking substance changes phase with a change in temperature of the heated non-combusted cigarette, so that low-boiling-point and volatile components in the aroma in the cooling unit body 41 are uniformly and slowly released in the smoking process.
4. The present invention can be used not only as a cooling member and an aroma-enhancing member for a heated aerosol-generating product, but more importantly, as a barrier member for an aerosol-generating material unit 3 of the heated aerosol-generating product, and when the aerosol-generating material unit 3 of the heated aerosol-generating product is a paste-like aerosol-generating material, the structure of the cooling unit 4 can prevent the paste-like aerosol-generating material in the aerosol-generating material unit 3 from being pushed when the heated aerosol-generating product is inserted into a heated non-combustible smoking set. When the aerosol-generating material unit 3 of the heated aerosol-generating article is a particulate aerosol-generating material, the temperature-reducing unit 4 is of its own configuration and, because the diameter of the airflow passage is smaller than the diameter of a single particle of the particulate aerosol-generating material, that is, the airflow passage 42 does not allow the particulate aerosol-generating material to pass through, the temperature-reducing unit 4 can serve as a barrier member for the particulate aerosol-generating material, preventing the particulate aerosol-generating material from falling onto other units of the heated aerosol-generating article.
5. The cooling unit prepared from the porous inorganic material and the porous natural wood material can reduce the temperature of smoke, can supplement fragrance loss caused by cooling while cooling, and can be used as a blocking component of an aerosol generating material when used for a product of a granular aerosol generating material or a paste aerosol generating material. It is known that the design of the structure should have smaller and fewer air flow passages in order to provide the blocking function, and the design of the structure should have larger and more air flow passages in order to provide the cooling and flavoring functions, which are not compatible. The invention just uses the cooling unit made of porous inorganic material and porous natural wood material, so that the cooling unit has three functions of cooling, aroma enhancement and obstruction.
6. In the scheme of the preferred heating type aerosol generating product of the invention, the cooling unit 4 can be used as a blocking component of the granular aerosol generating material, and the cooling unit main body 41 is made of porous inorganic material and porous natural wood material, so that the cooling unit is nontoxic, harmless and high in safety after being heated, and the problem that the blocking component of the granular aerosol generating material is made of organic polymer material and is softened and deformed under the action of high temperature to release harmful substances in the prior art is solved.
7. In the fragrance slow-release cooling unit of the invention, the fragrance component not only refers to the above-mentioned perfume, but also includes the case that the porous plant material carries the fragrance component, for example, when moso bamboo is used as the raw material of the cooling unit main body 41, the fragrance component can be natural bamboo fragrance carried by the moso bamboo raw material, at this time, the fragrance slow-release cooling unit can be used as a blocking component (spacer) of a granular aerosol generating material or a paste aerosol generating material of an aerosol generating product, namely, the fragrance slow-release cooling unit can play a role in blocking and can further compensate fragrance loss caused by aerosol cooling.

Specific differences between cooling units in samples of different heated aerosol generating articles are shown in table 1.
TABLE 1 Distinguishing of Cooling units in samples of different heated aerosol generating articles
Example 6:
carrying out sensory evaluation on the heating type aerosol generating product comparison sample 1-2 and the heating type aerosol generating product sample 1-5, mainly investigating three aspects of aroma, smoke and taste characteristics, wherein the three aspects comprise aroma quality, aroma quantity, miscellaneous gas, concentration, strength, fineness, irritation, dry feeling, cleanness degree and sweet return 10 indexes; the scoring values of the 10 quality detection indexes are respectively as follows: 0-10 minutes of fragrance quality, 0-10 minutes of fragrance amount, 0-10 minutes of miscellaneous gas, 0-10 minutes of concentration, 0-10 minutes of strength, 0-10 minutes of fineness, 0-10 minutes of irritation, 0-10 minutes of dry feeling, 0-10 minutes of cleanness degree and 0-10 minutes of rewweet. The more obvious the feeling is among seven indexes of aroma quality, aroma quantity, concentration, strength, fineness, cleanness degree and sweetness, the higher the score is, and the less obvious the sensory feeling is among three indexes of miscellaneous gas, irritation and dryness, the higher the score is. The results are shown in Table 2.
TABLE 2 sensory evaluation results of the samples
It can be known by combining table 2 that, compared with the comparison sample 1-2, the sample 1-5 has obvious improvement in the aspects of aroma quality, aroma amount, miscellaneous gas, concentration, strength, fineness, irritation, dryness, cleanness and ten sweet-back smoking feelings, especially, compared with the comparison sample 2, the cooling unit in the comparison sample 2 is made of common plastics, after smoking is finished, the cooling unit is heated to be softened, and the irritation smell of the heated plastics can be obviously smelled, and the cooling unit main body of the sample 1-5 is made of porous inorganic materials and porous natural wood materials, and is non-toxic, harmless and high in safety after heating. On the other hand, the material of the cooling section commonly used in the prior art is mainly polylactic acid, and the comparative sample 1 takes polylactic acid as the raw material of the cooling unit, the temperature entering the mouth of a smoker during smoking is about 38.3 ℃, while the temperature entering the mouth of the smoker during the smoking of samples 1-5 is 37.5 ℃, that is, the cooling effect of the cooling unit of samples 1-5 is close to that of the comparative sample 1, even better than that of the comparative sample 1, and the reason is that: 1. the cooling unit bodies of samples 1-5 are made of porous inorganic materials and porous natural wood materials, and the microscopic porous structure of the cooling unit body 41 can well increase the contact area with the flue gas, so that the cooling effect of the flue gas is improved; 2. the porous characteristic of the cooling unit of the samples 1-5 enables the amount of the adsorbed perfume to be larger and the perfume substances to be uniformly distributed, and the perfume is heated and volatilized to absorb part of the heat of the flue gas in the process that the flue gas passes through the cooling unit, so that the temperature of the flue gas is further reduced.
In summary, the cooling unit made of the porous inorganic material and the porous natural wood material of the present invention can not only reduce the temperature of the flue gas, but also supplement the fragrance loss caused by cooling while cooling, and further, when the cooling unit is used for the product of the granular aerosol generating material or the paste aerosol generating material, the cooling unit can also be used as a blocking component of the aerosol generating material, that is, the cooling unit made by the present invention can replace the cooling component, the blocking component and the fragrance increasing component in the prior art. It is known that the design of the structure should have smaller and fewer air flow passages in order to provide the blocking function, and the design of the structure should have larger and more air flow passages in order to provide the cooling and flavoring functions, which are not compatible. The invention just uses the cooling unit made of porous inorganic material and porous natural wood material, so that the cooling unit has three functions of cooling, aroma enhancement and obstruction.
