    The present invention preferably relates to a smoking article which is capable of producing substantial quantities of aerosol, both initially and over the useful life of the product, without significant thermal degradation of the aerosol former and without the presence of substantial pyrolysis or incomplete combustion products of sidestream aerosol. The article of the present invention is able to provide the user with the sensations and benefits of cigarette smoking without the substantial combustion products produced by burning tobacco in a conventional cigarette. In addition, the article may be made virtually ashless so that the user does not have to remove any ash during use. Preferred embodiments of the present smoking article comprise a short combustible carbonaceous fuel element, preferably less than 30 mm in length prior to smoking and less than about 8 mm in diameter a short, heat stable, preferably carbonaceous substrate bearing an aerosol forming substance, an efficient insulating means, and a relatively long mouthend piece. The fuel element is provided with a plurality of longitudinally extending passageways which act to control the heat transferred from the burning fuel element to the aerosol generating means.

    at the opposite end of the mouthpiece 2, a separate tool that creates an aerosol that includes the formation of an aerosol material 3 n located between the fuel element 1 and muzzetchuko 2o. in which the aerosol-forming material is enclosed, and the layer of tobacco-containing mass 4 can enclose the container 5, which is in contact with the fuel cell 1, while the fuel cell can be covered by isolate With fiberglass core element 6 Layer 4 of tobacco-containing mass is enclosed in a shell 7 of plain paper that prevents it from being eroded. The length of the fuel cell 1 is 15-20 mmo. It is recommended to supply three with the fuel cell 1: Or with more holes 8e. To increase the air flow through the fuel cell.
    The aerosol-forming material is a granulated substrate and / or compacted; tobacco „The open end of the metal container covers 3-5 mm back of the fuel cell 1” The opposite end of the metal container 5 is folded to form a wall 9, which is equipped with a large number of passages: or channels 10, guaranteeing the free passage of gases, tobacco aromas or odors and / or aerosol forming material directly into the delivery channel 11 aerosols.
    The plastic tube 12 joins end to end or overlaps the end covered with a wall 9, a metal container 5; The plastic tube is surrounded by a ring section 13 made of high density, elastic acetate cellulose. At the combustible end: the ring section 13 can be applied a layer 1 after 14 or other similar material to seal the ring section and block the flow of air through it. A low-e (M) leak filter 15 is inserted into the mouthpiece of the smoking article, it is recommended that the ring section 13 and the filter 15 be turned

    They were tied with ordinary wrapping paper 16, forming a set of 2 pieces. Another layer of regular I7 cigarette paper can be used to connect a layer of tobacco-containing mass 4 and a section of muvshtuk 2 with cellulose acetate fiber and a filter
    Alternatively, the layer 4 of the tobacco-containing mass can be used instead of the ring-shaped section 13 made of acetate-cellulose fiber so that the layer 4 extends from the burning end of the smoking article to the filter 15. The layer of glue is recommended to be applied to the ring-shaped sections of the filter 15, which is abutted 4 tabacsoderdal mass or you can place a short ring-shaped section of acetylcellulose fiber between the layer of tobacco-containing mass and the filter, in which case the glue can be applied any end
    Fig. 5 shows a variant of the invention in which the fuel cell I has a length of 10-15 mm and is overlapped with an insulating glass fiber insulating element 6, and the means creating. the aerosol is surrounded by a layer 4 of tobacco-containing mass. Preferably, the glass fibers used in this embodiment have a softening point below 650 s. The fibers in the process of use melt about the glass fiber Element 6 and the layer 4 of tobacco is wrapped with a sheath of special wrapping paper 16 and are interconnected by means of a layer 18 of cigarette paper. The metal container 5 blocks 3-4 mm of the back part of the fuel cell I in order to position it at a distance of about 6 to 12 mm from the fire end of the smoking article, and the rear part of the container 5 otbortovyvaets or folded so that it has the form of projections Figo 7 "
    In the mouth end of the container a channel 19 is formed along its center. Four additional channels 20 are formed in transitional areas between the bent and non-bent portions of the container. The rear part of the container may have a rectangular or square section instead of protrusions, or a simple tubular capsule with flanged section can be used here.
    51
    or curved tapered end with or without peripheral channels 20 or with them,
    The capsular end of the plastic tube 12 (fig. 3) is at a certain distance from the container 5. Therefore, the hot vapor passing through the channels 20 also passes through the tobacco layer 4, where the volatile components of the tobacco evaporate or are extracted. , after which the hot vapors enter channel 11 where layer A is joined right next to section 13 of cellulose acetate fiber
    Conce
    After the smoking article is ignited, the fuel cell begins to burn, causing heat to be used to volatilize the aerosol forming material or materials present in the aerosolis formation unit. Volatile substances are directed toward the mouthpiece, especially during puffing, and further into the mouth. a user where they create an almost complete illusion of smoking regular cigarettes
    Since the fuel cell is relatively short, the hot fire cone is always close to the aerosol forming device, which maximizes the transfer of heat to the aerosol forming agent and to any optional tobacco loads, and also contributes to more intensive formation of the final aerosol and the optional tobacco flavor. Never remains non-combustible part of the fuel cell which can
    act as a heat sink A small fuel cell also tends to minimize the amount of pyrolysis products or incomplete combustion, especially in variants that contain carbon and / or multiple channels
    Heat transfer, and therefore the supply of aerosols, also increase and become more intense
    by using channels passing through the fuel cell that draw in hot air and feed it into aerosol formation means, especially during tightening. It should also be borne in mind that the recommended insulating element always tends to limit, direct and concentrate heat towards
    146
    to the central core of the smoking article, thereby increasing the amount of heat transferred to the aerosol forming material
    Since the aerosol-forming material is physically isolated from the fuel cell, it is exposed to significantly lower gravity temperatures. with those that are present in the very cone of the fire of the burning element. This minimizes the likelihood of thermal degradation of the aerosol-forming material, which also contributes to the formation of aerosols during tightening, however, during slower smoldering, the aerosols are minimal in the aerosol formation means.
