The heated cigarette of the present invention is used in conjunction with a heating appliance, which, after being inserted into the heating appliance and heated, releases aerosol and aroma for smoking by the smoker.
Fig. 1 is an axial sectional structural view of an exemplary embodiment of the present invention. As shown in fig. 1, the heated cigarette of the present invention comprises a tobacco section 1, a multi-concave arc-shaped hollow filter rod cavity section 2 and a proximal lip section 3, which are coaxially connected in sequence, and outer wrapping materials 4, 5 which confine the tobacco section 1, the multi-concave arc-shaped hollow filter rod cavity section 2 and the proximal lip section 3.
The heated cigarette of the present invention comprises two ends: an upstream end portion and a downstream end portion. The terms "upstream" and "downstream" are used to describe the relative positions of elements or portions of elements of a cigarette with respect to the direction of smoking of the cigarette by a user during use. In use, a user may draw on the downstream end and the aroma and aerosol generated by the tobacco rod flow in the upstream to downstream direction and are drawn into the user's mouth.
A multi-concave arc hollow filter rod cavity section 2 is provided adjacent the downstream side of the tobacco section 1. The multi-concave arc hollow filter stick cavity section 2 is composed of a multi-concave arc hollow filter stick 21 and a paper tube 22 wrapping the multi-concave arc hollow filter stick. The material of the multi-concave arc-shaped hollow filter rod cavity section 2 is preferably a general safety material for cigarettes which is proved by practice. Preferably, the multi-concave arc-shaped hollow filter rod 21 comprises acetate fiber tows, triacetin and the like, so that it is very safe for a human body. In addition, the multi-concave arc hollow filter rod cavity body section 2 has better cooling effect. Firstly, the multi-concave arc hollow filter rod cavity section 2 forms a multi-concave arc structure, and the structure has a cooling effect. Second, the mixed material that forms after the cellulose acetate of many concave arc hollow filter rod cavity section 2 combines with triacetin, the material also can absorb certain heat, when the aerial fog that has higher temperature (200 ~ 350 ℃) and the fragrance that come from tobacco section 1 pass through this many concave arc hollow filter rod cavity section 2, can play certain cooling effect, thereby can reduce the sensation of burning or do not have the burning sensation when aerial fog and fragrance reach user's mouth, further promote the suction and experience. The surface of the multi-concave arc hollow filter stick can also be provided with a layer of forming paper (not shown).
Preferably, the ends of the interior of the paper tube 22 of the multi-concave arc hollow filter rod cavity section 2 are provided with cavities of a specified length. Namely, two cavities with a specified length are respectively arranged between the end surface of the multi-concave arc hollow filter stick 21 and the corresponding end surface of the paper tube 22, and comprise a first cavity 23a and a second cavity 23 b. The predetermined length is 0.5mm to 5 mm. Preferably, the prescribed length is 4 mm. By providing a cavity at both ends inside the paper tube 22, two buffer zones can be created when transporting flue gas. Specifically, the smoke enters the first cavity 23a after passing through the tobacco segment 1, enters the multi-concave arc-shaped hollow filter stick 21 after being temporarily gathered in the area of the first cavity 23a, enters the second cavity 23b after passing through the multi-concave arc-shaped hollow filter stick 21, and enters the near-lip segment 3 after being temporarily gathered again in the area of the second cavity 23 b. By arranging the two times of buffering between the upstream and the downstream of the smoke, the temperature of the smoke can be effectively reduced, so that burning and irritation of the smoke when the smoke reaches the oral cavity of a consumer can be reduced.
The specific structure of the multi-concave arc hollow filter stick 21 will be described in detail with reference to fig. 2 to 3. Figure 2 is a schematic end view of a multi-concave curved hollow filter rod according to one embodiment of the present invention; figure 3 is a schematic end view of a multi-concave curved hollow filter rod according to another embodiment of the invention. The multi-concave arc hollow filter stick 21 is in a hollow column shape and is provided with an inner hole 211 which is axially communicated. The cross-sectional shape of the inner hole comprises regular shapes such as a circle, a pentagram and a heart and other irregular shapes. When the cross section of the inner hole is circular, the diameter of the circle is 1.5 mm-3.5 mm. When the cross section of the inner hole is in a pentagram shape or a heart shape, the diameter of a circumscribed circle of the shape is 1.5 mm-3.5 mm. In some preferred embodiments, the inner bore diameter may be 2.0mm, 2.5mm, 3.0mm, 3.5mm, etc. Through setting up this axial hollow structure, can be so that the flue gas receive less resistance to suction at the in-process through many concave arc hollow filter rods 21, can guarantee that the smog volume in the flue gas keeps higher concentration for the flue gas can make the consumer obtain better suction satisfaction when reaching the consumer oral cavity.
Further, the outer surface of the multi-concave curved hollow filter rod 21 has a plurality of concave curved grooves 212 extending longitudinally of the filter rod. The number of the arc-shaped grooves 212 is between 4 and 10. Preferably, the number of the arc-shaped slots 212 is between 5 and 8. In the embodiment shown in fig. 2, the arcuate slots 212 are 6 grooves evenly distributed on the outer circumferential surface. The slot depth of the arc-shaped slot 212 is between 0.5mm and 2mm, preferably between 0.8mm and 1.5 mm. The slot width of the arcuate slot 212 is between 1mm and 3mm, preferably between 1.5mm and 2.5 mm. The arc-shaped groove 212 which longitudinally runs through and extends is arranged on the outer surface of the filter stick 21, so that the effects of further reducing the suction resistance of the filter stick and ensuring the smoke quantity in the smoke to keep higher concentration are achieved. In addition, the arc-shaped groove 212 changes the flowing path of the smoke, increases the contact area between the smoke and the hollow filter stick 21, and can play a role in further reducing the temperature through the specific smoke running path.
Preferably, the paper tube 22 of the multi-concave arc hollow core filter rod cavity section 2 may be 0.5mm thick. The multi-concave arc hollow filter rod cavity section 2 preferably has an outer diameter approximately equal to the outer diameter of the tobacco section 1.
Preferably, the multi-concave arc hollow core filter rod cavity section 2 has an outer diameter of at least 4mm, and may have an outer diameter of between about 4mm and about 10mm, and further between about 6mm and about 8 mm. In a preferred embodiment the multi-concave arc hollow core filter rod cavity sections 2 have an outer diameter of 7mm +/-10%.
The multi-concave arc hollow filter rod cavity segments 2 may have a length of between about 5mm and about 30 mm. In a preferred embodiment the multi-concave arc hollow core filter rod cavity segments 2 may have a length of about 23 mm. Specifically, the multi-concave arc hollow filter stick 21 is 15mm, and the cavities 23a and 23b at the two ends are respectively 4 mm.
The structure of the tobacco section 1 is explained in detail below. The tobacco segment 1 can be a tobacco core rod, is arranged at the upstream end part of the heated cigarette and is composed of tobacco core material and aluminum foil composite forming paper or oil-proof forming paper wrapping the tobacco core material. Specifically, the aluminum foil composite formed paper has a composite layer structure with an inner layer being an aluminum foil layer and an outer layer being a formed paper layer, the inner and outer layers being bonded together, for example, by an adhesive to form the composite layer structure. By providing the composite paper of aluminium foil on the tobacco segment, contamination and deformation of the outer wrapper due to moisture in the air being absorbed by the smoking material can be reduced. In further embodiments, the aluminum foil composite forming paper may also be replaced by an oil resistant forming paper.
Preferably, the tobacco core material of the tobacco segment 1 is a reconstituted tobacco material, a raw tobacco material or a coated paper material. Tobacco segment 1, when heated, can produce an aerosol and flavor that provides the smoker with a flavor similar to that of a conventional cigarette. Specifically, the core of the tobacco segment 1 is formed by longitudinally gathering a plurality of long strips of sheets cut from the reconstituted tobacco material, the raw tobacco material or the coated paper material. The elongated sheet of the present invention has a substantially flat surface. By "longitudinal" is meant the direction between the upstream and downstream ends of the cigarettes.
The core of the tobacco section 1 is formed by gathering long-strip-shaped thin sheets along the longitudinal direction of the cigarette. The term "sheet" means that the element has a width and length that is significantly greater than its thickness. The term "gathering" is used to describe the gathering, of the elongated sheet generally parallel to the longitudinal axis of the cigarette.
Cigarettes comprising elongate sheets (tobacco sheets) have the potential to significantly reduce the risk of loosening of the ends of the cigarettes, which is known to be due to loss of pieces of tobacco material from the ends of the cigarettes, compared to cigarettes comprising pieces of tobacco material. Loosening of the ends of the tobacco rods can result in frequent cleaning of the heating device (smoking set) when the rods are used with the heating device, and thereby affect the useful life of the heating device.
Furthermore, movement of the pieces of tobacco material may be caused when the heating element of the heating appliance is inserted into or withdrawn from a cigarette comprising pieces of tobacco material, which may disadvantageously result in the need for frequent cleaning of the heating element of the heating appliance to remove the fallen pieces of tobacco. In contrast, the heating element of the heating appliance advantageously does not cause the tobacco sheet to move when inserted into or withdrawn from a cigarette comprising the tobacco strip sheet.
In addition, the weight of a particular length of the elongated sheet is determined by the density, width and thickness of the sheet, and therefore, the weight of a particular length of a cigarette comprising tobacco segments into which the elongated sheet is gathered can be adjusted by controlling the density and size of the elongated sheet, which reduces weight inconsistencies between cigarettes of the same size, and reduces the rate at which the weight falls outside of acceptable limits compared to cigarettes comprising pieces of tobacco material.
One or more of tobacco extract, granular or powdered tobacco material or flavourant is/are applied to the core material of the tobacco segment 1. Among these, tobacco extracts include, but are not limited to: yunyan absolute, Zimbabwe absolute, megastigmatrienone, methyl cyclopentenolone, damascenone, ionone, dihydroactinidiolide, and the like. Flavorants include, but are not limited to: mint essence, apple essence, rose essence and the like. Further, the core material is a sheet material formed by a paper-making process. In the present invention, the smoking material/agent is not included in the substance applied to the core of the component material. Known smoking materials include, but are not limited to: polyols and mixtures thereof. Polyhydric alcohols such as propylene glycol, triethylene glycol, butylene glycol, and glycerin.
