[0034] Heat-not-burn tobacco products have attracted much attention because they are closest to traditional cigarettes in terms of sensory quality and smoking methods. However, in the related art, heated cigarettes have problems such as tobacco shreds easily falling off and tobacco shreds easily remaining in the smoke duct of heated smoking devices, which is difficult to clean.

[0035] The inventors of the present disclosure have attempted to solve the above problem by adding a sealing film to the smoking section of the heated cigarette, but adhesive is needed to stick the sealing film to the end of the smoking section. The introduction of adhesive may affect the taste or flavor of the heated cigarette, and new production equipment needs to be designed.

[0036] In the process of implementing the present disclosure, it was found that a plugging section formed of a paper base can be added at the end of the smoking section to prevent the smoking medium of the smoking section from falling off, without the need to introduce substances such as adhesives, and will not affect the taste or flavor of the heated cigarette.

[0037] In view of this, the present disclosure provides a heated cigarette. Figure 1 A cross-sectional schematic diagram of a heated cigarette according to an embodiment of the present disclosure is shown.

[0038] like Figure 1 As shown, the heated cigarette comprises a filter segment 1, a smoking segment 2 and a plug segment 3 connected in sequence. The plug segment 3 is formed by folding a paper base for multiple times.

[0039] According to the embodiments of the present disclosure, by providing a plugging section 3 at the end of the smoking section 2 of the heated cigarette, the smoking medium of the smoking section 2 can be effectively prevented from falling off, and water, tar and other substances can be effectively prevented from flowing from the smoking section 2 into the heated cigarette device; the plugging section 3 is formed by multiple foldings of the paper base and is contained at the end of the heated cigarette, and there is no need to introduce adhesives and other substances, and there is no odor when heated, and the taste or flavor of the heated cigarette will not be affected, and the preparation process is simple and the production efficiency is high; after the heated cigarette is smoked, no smoking medium will remain in the heated cigarette device, and the next cigarette can be smoked without cleaning, which improves the experience. In addition, the outer paper tube of the heated cigarette is very clean after heating, without carbonization, tar leakage, and odor.

[0040] According to the embodiment of the present disclosure, the plugging section 3 can be accommodated at the end of the cigarette paper of the smoking section 2, or the end section and the smoking section 2 can be connected through an outer layer of cigarette paper.

[0041] According to an embodiment of the present disclosure, the direction of the paper base folding may be the axial direction of the plug section 3.

[0042] The heated tobacco products provided by the embodiments of the present disclosure can be adapted to circumferential heating smoking devices or central heating smoking devices. The heating method of heat-not-burn smoking devices is mainly resistive heating, and the resistive heating method is divided into central heating and circumferential heating. Among them, in the circumferential heating smoking device, since the heat radiates from the circumference to the center, the utilization rate of the cigarette rod is improved, but the heat loss is relatively high, and paper smell may be generated during the heating process, resulting in a poor experience for consumers. The central heating smoking device has the advantages of a large heat transfer surface, high energy utilization rate, high heating efficiency, etc., and is also the mainstream heating method of existing heat-not-burn smoking devices. However, there are common pain points that need to be solved urgently. For example, after the heated tobacco product is smoked, the adhesion force between the smoke-generating medium and the heating component 5 of the central heating smoking device increases, making it impossible to directly pull out the heated tobacco product. Usually, a specific cigarette-taking structure in the central heating smoking device is required to take out the heated tobacco product.

[0043] According to an embodiment of the present disclosure, as Figure 2 shown, the plug section 3 is configured to allow the heating component 5 of the central heating smoking device to penetrate. When the heated tobacco product is pulled out from the heating component 5, the plug section 3 supports the smoke-generating section 2, so that the heated tobacco product is separated from the heating component 5. Thus, the heated tobacco product can be directly pulled out from the heating component 5 of the central heating smoking device without relying on a specific cigarette-taking structure in the central heating smoking device.

[0044] After the heated tobacco product is pulled out from the heating component 5 of the central heating smoking device, the heating component 5 is usually attached with residues and tar, which easily causes damage or failure of the central heating smoking device. In the embodiments of the present disclosure, as Figure 2 shown, the plug section 3 is configured to allow the heating component 5 of the central heating smoking device to penetrate and clean the heating component 5 when the heating component 5 is pulled out. By arranging the plug section 3 at the end of the smoke-generating section 2, the heating component 5 of the central heating smoking device can penetrate the plug section 3 and enter the smoke-generating section 2. After smoking, the heating component 5 can be directly pulled out from the heated tobacco product. When pulled out, the plug section 3 can clean the residues and tar attached to the heating component 5, reduce the pollution of the heating component 5, and improve the heating efficiency of the heating component 5.

[0045] According to an embodiment of the present disclosure, the plug section 3 has a plurality of holes penetrating both sides, and the area of the plurality of holes penetrating both ends accounts for 10% - 30% of the end area of the plug section 3. Optionally, the area of the plurality of holes penetrating both ends can account for 10%, 12%, 15%, 18%, 20%, 22%, 25%, 28%, 30% of the end area of the plug section 3, or any range composed of any two of the above values. The plurality of holes penetrating both sides in the plug section 3 can allow the gas to flow smoothly into the heated tobacco product when smoking the heated tobacco product.

[0046] According to an embodiment of the present disclosure, the length of the plug section 3 can be 3 to 9 mm. Optionally, the length of the plug section 3 can be 3 to 5 mm. Exemplarily, the length of the plug section 3 can be 3 mm, 4 mm, 5 mm, 5.5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or a range composed of any two of the above values. If the plug section 3 is too short, when the heating component 5 of the central heating smoking device penetrates or pulls out from the heated cigarette, the plug section 3 is likely to fall off; if the plug section 3 is too long, the length of the smoking section 2 is reduced, and the manufacturing cost increases.

[0047] According to an embodiment of the present disclosure, the basis weight of the paper substrate is 20 to 100 g / m 2 , optionally, the basis weight of the paper substrate can be 25 to 50 g / m 2 . Exemplarily, the basis weight of the paper substrate can be 20 g / m 2 , 25 g / m 2 , 30 g / m 2 , 35 g / m 2 , 40 g / m 2 , 45 g / m 2 , 50 g / m 2 , 55 g / m 2 , 60 g / m 2 , 70 g / m 2 , 80 g / m 2 , 90 g / m 2 , 100 g / m 2 or a range composed of any two of the above values.

The natural color cellulose paper substrate is prepared in a conventional manner: using natural color pulp to produce the paper substrate, and the natural color pulp is an existing commercial pulp, which is yellow wood pulp that has not been bleached; no fillers are added during the production of the paper substrate; the basis weight of the paper substrate can be 10 to 60 g / m 2 , preferably, it can be 20 to 40 g / m 2 .

[0049] According to an embodiment of the present disclosure, the length of the paper base can be equal to the length of the plug section 3, and the width of the paper base can be 8 to 30 cm. Exemplarily, the width of the paper base can be 8 cm, 9 cm, 10 cm, 12 cm, 15 cm, 18 cm, 20 cm, 22 cm, 25 cm, 28 cm, 30 cm or a range consisting of any two of the above values. Specifically, the above-mentioned paper base can be cut into 8 to 30 cm wide according to the design needs of the plug section 3. The cut paper base is embossed by a roller. Before entering the smoke gun, the paper base is pre-folded and formed step by step by two pairs of rollers. After the pre-folded embossed paper comes out of the double rollers, the belt driven by the motor drives the belt to pull the folded pre-embossed paper to reduce slippage. At the same time, the pulley squeezes and fixes the folded embossed paper to a certain extent, thereby improving the pore uniformity and roundness to a certain extent, and finally wrapped by the molding paper to form the plug section 3.

[0050] According to an embodiment of the present disclosure, the paper base can be formed by interweaving fibers. The paper base can be formed with embossing, and at the embossing, the proportion of fiber breakage can be 5% to 20%, so that the paper base is in a state of being to be broken but not broken. Exemplarily, the proportion of fiber breakage can be 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20% or a range consisting of any two of the above values. When the heated cigarette is smoked and pulled straight from the heating component 5 of the central heating device, the paper base in the state of being to be broken but not broken can clean the heating component 5 by friction, and avoid excessive friction to pull out the plug section 3; in addition, the paper base is in a state of being to be broken but not broken, which increases the air permeability of the plug section 3 and improves the smoking quality.

[0051] The depth of embossing can be determined according to the thickness of the paper base, and it is sufficient to ensure that the paper base is in a state of being ready to be broken but not yet broken.

[0052] According to an embodiment of the present disclosure, the embossed width of the embossed paper base may be 3-8 mm. For example, the embossed width of the embossed paper base may be 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, or a range consisting of any two of the above values.

[0053] According to the embodiments of the present disclosure, a heat-resistant layer can be formed on one or both sides of the paper base by in-situ polymerization of a silicone oil reagent. Exemplarily, a heat-resistant layer can be formed on one side of the paper base by in-situ polymerization of a silicone oil reagent, or on both sides of the paper base by in-situ polymerization of a silicone oil reagent. The heat-resistant layer formed in situ has good heat resistance, good stability in a high temperature environment, and will not decompose or volatilize, which is beneficial to block the heat conduction between the heating component 5 and the paper base, thereby improving the heat resistance of the paper base, and even when the heated cigarette is smoked, the high temperature in the central heating device will not cause obvious carbonization to the paper base. In addition, the heat-resistant layer formed by in-situ polymerization of a silicone oil reagent has no odor when heated, and will not affect the taste or flavor of the heated cigarette.

[0054] In some embodiments of the present disclosure, a silicone oil reagent may be coated on the surface of a paper base, and then the silicone oil reagent may be polymerized in situ to form a temperature-resistant layer.

[0055] It should be noted that the silicone oil reagent may include a solvent in addition to amino silicone oil and / or vinyl silicone oil, so that the amino silicone oil and / or vinyl silicone oil are evenly coated on the surface of the paper base.
