Technical Field
The invention relates to the technical field of aerosol generation, in particular to an aerosol generating product.
Background
In recent years, as international smoking control exercise steps have been accelerated, the restriction of smoking by governments, particularly smoking in public places, has become more severe. Novel tobacco products such as low-temperature cigarettes (non-burning by heating), smokeless tobacco products, electronic cigarettes and the like are popular with tobacco consumers at home and abroad.
The heating non-combustion type cigarette as one kind of novel tobacco products is mainly characterized in that tobacco is not combusted, and only a small amount of second-hand smoke exists, so that the cigarette is attracted by various international large tobacco companies. At present, a heating non-combustion type cigarette product mainly comprises two parts: the cigarette and the heating device, wherein the cigarette is basically not different from the common cigarette, the cigarette accords with the characteristics of heating the non-combustion type cigarette, but needs to carry the heating device, and brings inconvenience to consumers.
And a novel tobacco product is also provided, and the cigarette is provided with a heating source and is convenient to carry. Existing self-heating non-combustible cigarettes comprise a self-heating source located at the end of the cigarette, for example carbon, and tobacco shreds, which are wrapped in cigarette paper. The cigarette paper comprises an aluminum foil and a paper layer which is not combusted by heating, wherein the aluminum foil wraps tobacco shreds and a self-heating source, and the paper layer is wrapped by the aluminum foil. After the charcoal is ignited, the aluminum foil transfers heat to the tobacco shreds, the tobacco shreds are not combusted but atomized, and smoke generated by atomization of the tobacco shreds is used for suction.
There is a description of a cigarette paper improved to accommodate a cigarette which is not burned by heating, for example, chinese patent publication No. CN104452479B discloses a composite cigarette paper which is similar in appearance to a conventional cigarette and which is a unique novel tobacco product which is not burned at a low temperature by heating tobacco shreds through an aluminum foil layer by heat generated by burning an outer layer cigarette paper during smoking and by sucking volatile components such as flavor components and nicotine generated by heating and volatilizing the tobacco shreds into an oral cavity.
For another example, chinese patent publication No. CN204224923U discloses a cigarette paper with a certain thickness, high air permeability and high grammage, which is then combined with an aluminum foil by a bonding agent, and then subjected to laser, electrostatic or mechanical perforation, so that the cigarette made of the cigarette paper has an appearance similar to that of the existing cigarette, the aluminum foil layer is directly contacted with the tobacco shreds after the cigarette is rolled and formed, and when the cigarette is ignited, the aluminum foil is heated and transferred to the tobacco shreds by combustion of the cigarette paper layer, and the aroma components and volatile components such as nicotine generated by heating and volatilization of the tobacco shreds are sucked into the oral cavity, thereby forming a unique novel tobacco product.

The difference between sample 4 and sample 1 can be seen in table 3: the second part of sample 4 is a paper filter stick without a hollow inner cavity, but a plurality of gaps extending along the first direction, but the contents of glycerin and nicotine in sample 4 are only 1.17mg/cig and 0.85mg/cig, which are significantly lower than those of sample 1, and the smoke effect of sample 4 is not as good as that of sample 1.
The experimental results show that the aerosol generating product has good aerosol effect.
Experiment four
As in the previous embodiment, the periphery of the third portion 4 is provided with a plurality of spaced grooves 42, which can provide thermal insulation, lower the temperature of the suction end of the third portion 4, and prevent the user from burning the mouth during suction.
In the experiment, temperature detection is carried out, and a sample 1 (the aerosol generating product of the invention) comprises an aerosol generating substrate 1, a first part 2, a second part 3 and a third part 4 which are arranged in sequence along a first direction; sample 2 comprises an aerosol-generating substrate, a first portion, a second portion and a third portion arranged in sequence along a first direction; sample 2 differs from sample 1 in that the third portion of sample 2 is a solid filter rod, has no hollow lumen, and has no plurality of spaced grooves around its periphery.
The smoke emissions suction method is as follows: the number of cigarettes: a plurality of branches; power supply: triggering a key; a suction mode: sucking mouth by mouth; the number of each branch opening: 10 mouths; suction capacity: 55 mL; pumping time: 2 seconds; suction interval: 30 seconds; suction curve: a bell-shaped curve; the thermocouple was wrapped in the third part 4 with an insulating tape, the thermocouple temperature measurement point was 3.5mm from the suction tip of the third part 4, and the heating temperature was 310 ℃.
As can be seen from fig. 2, the periphery of the third portion 4 of the sample 1 is free of a plurality of grooves 42 arranged at intervals, and the maximum temperature of each suction during suction ranges from 29.3 ℃ to 34.9 ℃; the periphery of the third portion of sample 2 was not notched, and the maximum temperature per puff during aspiration ranged from 37.4 ℃ to 49.5 ℃. It can be seen that the temperature of the third portion 4 with the grooves 42 in the periphery used in sample 1 can be reduced by 8 to 14 c compared to the third portion without grooves in the periphery used in sample 2, and the temperature of the suction end of the third portion 4 of the aerosol-generating article of the invention is low, so that the user does not scald his mouth when sucking it.
The present invention also provides an aerosol-generating system comprising: an aerosol-generating article according to any one of the embodiments above; an aerosol-generating device (not shown) having a heating body (not shown) extending in the first direction for insertion into the aerosol-generating substrate 1. The specific shape of the heating body is not limited, and in this embodiment, the heating body is cylindrical and has a circular cross section. In other embodiments, the cross-section of the heating body may be quadrilateral, triangular or polygonal.
In summary, the above-mentioned embodiments are provided only for illustrating the principles and effects of the present invention, and not for limiting the present invention. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
