Description
Technical Field
The embodiment of the application relates to the technical field of products, in particular to an aerosol generating product, a preparation method thereof and an aerosol generating system.
Background
Smoking articles (e.g., cigarettes, cigars, etc.) burn tobacco during use to produce tobacco smoke. Attempts have been made to replace these tobacco-burning smoking articles by making products that release the compounds without burning.
An example of such a product is a heating device that releases a compound by heating rather than burning a smokable material in the article. For example, the smokable material may be tobacco or other non-tobacco products, which may or may not contain nicotine. As another example, there are heating devices that heat an article by infrared radiation to release a compound to produce an aerosol.
Because the infrared rays have stronger penetrability, the infrared rays can penetrate through the periphery of the product to enter the interior, so that the internal and external heating of the product is more uniform. Disadvantageously, such uniform heating causes a substantial portion of the moisture in the product to be vaporized by heat, while the higher heat-containing water vapor makes the user more prone to burning when inhaling, especially when inhaling the first bite.
Disclosure of Invention
In order to solve the problem that the existing product is easy to cause a smoker to produce a burning sensation during smoking when being heated by infrared radiation, the embodiment of the application provides an aerosol generating product, a preparation method thereof and an aerosol generating system.
As used herein, the term 'aerosol-forming substrate' is used to describe a substrate that is capable of releasing volatile compounds upon heating, which may form an aerosol. The aerosol generated by the aerosol-forming substrate of the aerosol-generating article described herein may be visible or invisible and may comprise droplets of vapor (e.g., fine particles of a substance, which particles are in a gaseous state, which particles are typically liquid or solid at room temperature) as well as gases and condensed vapors.
As used herein, the terms 'upstream' and 'downstream' are used to describe the relative positions of elements, or portions of elements, of the aerosol-generating article with respect to the direction in which a user draws on the aerosol-generating article during its use.

The aerosol-forming substrate 10 is disposed at a distal end 42 of the aerosol-generating article.
The aerosol-forming substrate 10 may comprise nicotine. The nicotine-containing aerosol-forming substrate 10 may comprise a nicotine salt matrix. The aerosol-forming substrate 10 may comprise a plant-based material. The aerosol-forming substrate 10 preferably comprises a tobacco-containing material.

The aerosol-forming substrate 10 may comprise one or more of the following materials: tobacco leaves, tobacco vein segments, reconstituted tobacco, homogenized tobacco, extruded tobacco, tobacco slurry, cast leaf tobacco, and expanded tobacco.
The aerosol-forming substrate 10 may comprise at least one aerosol-forming agent. An aerosol-former is used to describe any suitable known compound or mixture of compounds that promotes the formation of an aerosol in use and is generally resistant to thermal degradation at the operating temperature of the aerosol-generating article. Suitable aerosol formers are known in the art and include, but are not limited to: polyols such as propylene glycol, triethylene glycol, 1, 3-butanediol, and glycerol; esters of polyhydric alcohols, such as glycerol mono-, di-or triacetate; and aliphatic esters of mono-, di-or polycarboxylic acids, such as dimethyl dodecanedioate and dimethyl tetradecenedioate.

The aerosol-forming substrate 10 may also comprise one or more capsules comprising, for example, additional tobacco or smokeless volatile flavoring compounds, and such capsules may melt during heating of the aerosol-forming substrate 10.
The aerosol-forming substrate 10 may be provided on or embedded in a thermally stable carrier. The term "thermally stable" as used herein refers to a material that does not substantially degrade at the temperature to which the aerosol-forming substrate 10 is typically heated (e.g., about 150 ℃ to about 300 ℃). The carrier may take the form of a powder, granules, pellets, chips, strands, ribbons, or sheets.

The cooling element 20 is arranged immediately downstream of the aerosol-forming substrate 10 and is adjacent to the aerosol-forming substrate 10. In use, the volatile material released by the aerosol-forming substrate 10 after being heated passes along the cooling element 20 towards the proximal end 41 of the aerosol-generating article and may cool down within the cooling element 20 to form an aerosol for inhalation by a user. In the preferred embodiment shown in fig. 1, the cooling element 20 includes a cavity that extends along the length of the cooling element 20. By the above axially extending cavities, the air flow through the cooling element 20 is in the longitudinal direction without substantial radial deviation. The cooling element 20 may act to cool the temperature of the aerosol stream drawn through the cooling element 20 by means of heat transfer. The components of the aerosol will interact with the space within the cooling element 20 and lose thermal energy.
In some embodiments, the temperature of the aerosol stream may decrease by more than 10 degrees celsius as it is drawn through the cooling element 20. In some embodiments, the temperature of the aerosol stream may decrease by more than 25 degrees celsius or more than 30 degrees celsius as it is drawn through the cooling element 20.

To assemble the aerosol-generating article, the three elements described above are aligned and tightly wrapped within the outer wrapper 40. In the embodiment shown in fig. 1, the outer wrapper 40 may be conventional cigarette paper.
The aerosol-generating article shown in fig. 1 is designed to be engaged by an aerosol-generating device comprising a heating element for inhalation by a user. In use, the heating element of the aerosol-generating device heats the aerosol-forming substrate 10 of the aerosol-generating article to a temperature sufficient to generate an aerosol which is drawn downstream through the aerosol-generating article and inhaled by a user.
One embodiment of the present application also proposes an infrared absorbing material configured to absorb infrared radiation that heats the aerosol-forming substrate 10. In a preferred embodiment, the absorption peak of the infrared absorbing material is correlated to the absorption peak of moisture in the aerosol-forming substrate. In this way, the infrared absorption material absorbs radiation and heats the infrared rays of the aerosol forming substrate 10, so that the evaporated and atomized moisture is reduced in a certain proportion, the phenomenon that the smoker generates a burning sensation during smoking due to the fact that the vapor with higher heat is contained is avoided, and particularly, the temperature of the first-mouth smoking aerosol is reduced, and the smoking experience of a user is improved; meanwhile, after the temperature of the infrared absorbing material is increased, the infrared absorbing material can be heated and atomized together to form the matrix 10, so that the heating efficiency of the product is improved to a certain extent.
In one example, the wavelength range of the absorption peak of the infrared absorbing material at least partially coincides with the wavelength range of the absorption peak of the moisture in the aerosol-forming substrate 10. Specifically, the wavelength range of the absorption peak of the infrared absorbing material is within the wavelength range of the absorption peak of the moisture in the aerosol-forming substrate 10; alternatively, the wavelength range of the absorption peak of the moisture in the aerosol-forming substrate 10 is within the wavelength range of the absorption peak of the infrared absorbing material; alternatively, the wavelength range of the absorption peak of the infrared absorbing material partially coincides with the wavelength range of the absorption peak of the moisture in the aerosol-forming substrate 10; alternatively, the wavelength range of the absorption peak of the infrared absorbing material is exactly the same as the wavelength range of the absorption peak of the moisture in the aerosol-forming substrate 10.
In one example, the infrared absorbing material has an absorption peak in the wavelength range of 3 μm to 5 μm.
In one example, the infrared absorbing material is in at least one of the following forms: powder, granules, pellets, chips, strands, ribbons or sheets. An infrared absorbing material may be disposed between the aerosol-forming substrate 10 and the outer wrapper 40, for example, a sheet-shaped infrared absorbing material is sandwiched between the aerosol-forming substrate 10 and the outer wrapper 40; alternatively, an infrared absorbing material is disposed within the aerosol-forming substrate 10.
Taking the infrared absorbing material as a particle form, as shown in fig. 1, 11 in the figure represents a particle-shaped aerosol-forming substrate, 12 represents moisture in the particle-shaped aerosol-forming substrate, and 13 represents the particle-shaped infrared absorbing material; the particulate infrared absorbing material is mixed with the particulate aerosol-forming substrate and its moisture. When the product is heated by infrared radiation, the granular infrared absorbing material absorbs infrared rays of 3-5 mu m together with moisture; in this way, the evaporation and atomization of the water is reduced in a certain proportion, so that the phenomenon that the water vapor with high heat content causes burning sensation to the user during sucking is avoided, and the temperature of the first sucking air fog is reduced. Meanwhile, the temperature of the granular infrared absorbing material is increased after the granular infrared absorbing material absorbs the radiant heat, and the granular aerosol forming substrate adjacent to the granular infrared absorbing material is heated and atomized, so that the heating efficiency of the product is improved to a certain extent.
In one example, the infrared absorbing material includes at least one of a metal, an inorganic non-metal, an organic, and a super-absorbing material. For example, metals include, but are not limited to, copper, nickel; inorganic nonmetallic materials include, but are not limited to, silicon carbide, graphene; organics include, but are not limited to, sucrose, fiber; superabsorbent material: the surface microstructure of the substance is regulated so that the substance only absorbs infrared rays of 3-5 mu m.
In one example, the mass fraction of infrared absorbing material is between 2% and 30% based on the total mass of the aerosol-forming substrate 10 and the infrared absorbing material; preferably, between 2% and 25%; further preferably, between 2% and 20%; further preferably, between 2% and 15%; more preferably, the content is 5 to 15%.
The above outer wrapper 40 is preferably made of an infrared transmitting material. For example, the inorganic fiber material is used for preparation, and specifically comprises one or more of hydroxyapatite fiber, silicon carbide fiber and barium titanate fiber.
The above hydroxyapatite fiber, silicon carbide fiber, barium titanate fiber are excellent infrared-transmitting materials so that the outer wrapper 40 is substantially non-infrared-absorbing when the aerosol-generating article is heated by means of infrared radiation, thereby effectively promoting the heating efficiency of the inner aerosol-forming substrate 10.
Further to facilitate verification of the feasibility of aerosol-generating articles employing the above infrared absorbing materials, and the advancement in properties of the produced aerosol-generating articles, the produced aerosol-generating articles are illustrated by the following specific examples and test results.

Graphene materials may also be employed, wherein the mass fraction of the graphene material is 10%.
