Detailed Description
In order to more clearly explain the overall concept of the present application, the following detailed description is given by way of example in conjunction with the accompanying drawings.
In this application, it is to be understood that terms such as "including", "comprising" or "having", etc., are intended to indicate the presence of the disclosed features, numbers, steps, acts, components, parts, or combinations thereof, and are not intended to preclude the presence or addition of one or more other features, numbers, steps, acts, components, parts, or combinations thereof.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Referring to fig. 1-3, embodiments of the present application provide a heated smoking article 2 comprising: an aerosol substrate section 201, a cooling section 202 and a filtration section 203 arranged in sequence along the length of the heated smokable article 2; the cooling section 202 is used for cooling the smoke generated by heating the atomizing substrate section 201, and the filtering section 203 is used for filtering at least one component in the smoke.
The material within the aerosol substrate segment 201 generally volatilizes aerosol when heated. The material within the aerosol matrix segment 201 may be a non-tobacco containing material or a tobacco containing material. The material within the nebulized matrix segment 201 may include, for example, one or more of tobacco itself, a tobacco derivative, expanded tobacco, reconstituted tobacco, a tobacco extract, homogenized tobacco, or a tobacco substitute.
Of course, to integrate the aerosol substrate section 201, cooling section 202 and filter section 203, they are typically wrapped in a long stick of material (not shown), such as cigarette paper.
In order to lower the temperature of the fumes to a suitable temperature, the present application seeks two aspects. Two cooling methods are described below. It should be noted that these two means can be used in combination.
Referring to fig. 3, in the first temperature reduction means, the cooling section 202 includes a phase change coating 2024 coated on the inner surface of the main body structure, the phase change coating 2024 contains a phase change material, and the phase change material has a composition having at least two phase change temperatures in a temperature range of 45 ℃ to 150 ℃, and the phase change temperature is a solid-solid phase change temperature or a solid-liquid phase change temperature.
Solid materials absorb a large amount of heat energy when undergoing a phase change. The phase change material used in embodiments of the present application may be in a solid state after completing the phase change and remain within the phase change coating 2024. The phase-change material may be in a liquid state after completing the phase change, and the liquid may be adsorbed on the inner surface of the main structure of the cooling section 202 in a thin film form by controlling the content of the liquid. Some components of a phase change material may change phase at one temperature while other components change phase at another temperature. By controlling the component proportion of the different phase change materials, the temperature of the smoke can be controlled within a smaller temperature range. This smaller temperature interval is controllable, in other words customizable. Thus, user experience can be improved.
Of course, the phase change material may also be a single component.
The form in which the phase change material exists is not limited to the phase change coating. For example, the body structure of the cooling section may be multi-layered, the phase change material disposed in a nip between two layers, etc.
Optionally, the composition in the phase change material has at least two phase change temperatures in a temperature range of 52 ℃ to 100 ℃. In this way, the temperature of the smoke exiting the heated smoking article 2 can be brought closer to the temperature range at which the user feels comfortable.
Optionally, the phase change material comprises: polyethylene glycol, carnauba wax, polyvinyl alcohol, polyethylene, polylactic acid, and glucomannan.
Optionally, the phase change coating 2024 further comprises an auxiliary material, the auxiliary material for enhancing taste.
For example, the auxiliary material comprises at least one ingredient of essence, polysaccharide, and plant powder.
Optionally, the phase change material is recorded as 40 parts to 80 parts by weight, and the auxiliary material is recorded as 0.5 part to 10 parts by weight. If the specific gravity of the auxiliary material is too low, the taste improvement effect is not obvious, and if the specific gravity of the auxiliary material is too high, the cooling effect is influenced.
Optionally, phase change coating 2024 further comprises a thermally conductive material. The thermally conductive material serves to enhance the overall thermal conductivity of the phase change coating 2024.
For example, the thermally conductive material comprises graphite.
Optionally, the phase change material is recorded as 40 parts to 80 parts by weight, and the heat conduction material is recorded as 5 parts to 10 parts by weight. The heat conduction efficiency is influenced by too low specific gravity of the heat conduction material, and the cooling effect is influenced by too high specific gravity of the heat conduction material.
Optionally, the phase change coating 2024 further comprises a plasticizer. Thereby enhancing the flexibility of the phase change coating 2024 and facilitating processing.
For example, the plasticizer includes at least one component selected from glycerol, triacetin, carboxymethyl cellulose (CMC), and sodium alginate.
Alternatively, the phase change material is recorded as 40 parts to 80 parts by weight, and the plasticizer is recorded as 5 parts to 10 parts by weight. If the specific gravity of the plasticizer is too low, the property of the phase-change material is not obviously improved, and if the specific gravity of the plasticizer is too high, the cooling effect is influenced.
Optionally, the mass ratio of the phase change coating 2024 to the cooling section 202 is between 5% and 10%. If the phase change coating 2024 is too heavy, then when a solid-liquid phase change occurs, liquid droplets may fall off the inner surface of the body structure of the cooling section 202. If the phase change coating 2024 is too light, the cooling effect is not good.
Referring to fig. 1 and fig. 2, a second cooling means provided in the embodiment of the present application is: the cooling section 202 is provided with a plurality of vent holes 2023. Referring to fig. 4 and 5, when the heated smokable article 2 is inserted into the receiving cavity 101 of the smoking article body 1, the vent 2023 should be located outside the receiving cavity 101 or within the receiving cavity 101 but still in communication with the outside air. Thus, when the user inhales the smoke, fresh air flows into the cooling section 202 from the air vent 2023, diluting the smoke and lowering the temperature of the smoke.
Specifically, the vent holes 2023 may be in one or more rows along the circumference of the cooling section 202. Of course, the distribution pattern of the ventilation holes 2023 is not limited thereto.
Optionally, the ventilation rate of the cooling section 202 is between 10% and 70%. If the ventilation rate is too low, the cooling effect is not obvious. If the ventilation rate is too high, the smoke is too diluted, and the taste is affected.
Alternatively, referring to fig. 1, the body of the cooling section 202 is formed from a section of hollow paper cylinder.
Optionally, the cooling section 202 comprises at least two cooling subsections, and the vent 2023 opens on one of the cooling subsections.
Referring to fig. 2, the cooling section 202 is formed by connecting a first cooling subsection 2021 and a second cooling subsection 2022. The vent hole 2023 opens on the first cooling subsection 2021. Because the vent holes 2023 are closer to the atomizing substrate section 201, the cooling effect on the smoke is more obvious.
The cooling subsections are spliced by adopting a plurality of sections, on one hand, the processing is convenient, namely, the cooling subsections with the vent holes 2023 and the cooling subsections without the vent holes 2023 can be processed respectively. On the other hand, the lengths and the suction resistances of different cooling subsections can be flexibly adjusted, so that the gradient of the smoke temperature can be more accurately regulated, namely the smoke temperature can be flexibly and accurately regulated.
Optionally, the body of the vented cooling subsection is formed from a hollow paper tube. This is because the air holes 2023 are opened on the hollow paper cylinder, so that the outside air can be well introduced into the cooling section 202.
Optionally, the body of at least one section of the cooling subsegment is formed from a hollow acetate rod. The hollow acetate rod, in contrast, has a greater air resistance and slower heat dissipation from the smoke.

Figure BDA0002475534150000091
From the above results, it can be seen that when the cooling section 202 uses all hollow paper tubes, it is advantageous to reduce the temperature of the flue gas because the internal space is large. Further increasing the ventilation rate of the cooling section 202 vents 2023 also reduces the flue gas temperature by dilution with cold air, but as the ventilation rate increases the flue gas concentration, i.e. the amount of smoke, decreases. After the phase-change coating 2024 is adopted to coat the inner surface of the cooling section 202, the temperature reduction effect can be better while the larger smoke concentration is ensured.
