Throughout the drawings, the same elements are represented by the same or similar reference numerals. Conventional structures or constructions will be omitted where they may cause confusion in understanding this utility model.

[0034] Heated tobacco products have attracted much attention because they are closest to traditional cigarettes in terms of sensory quality and smoking method. However, among the related technologies, heated cigarettes have problems such as tobacco shreds easily falling off and tobacco residues in the flue of heated tobacco devices being difficult to clean.

[0035] This invention attempts to solve the above problems by adding a sealing film to the smoking section of heated cigarettes. However, 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 heated cigarettes, and new production equipment needs to be designed.

[0036] In the process of realizing this utility model, it was discovered that a paper-based plug section can be added to the end of the smoke-generating section to prevent the smoke-generating medium from falling off, and there is no need to introduce adhesives or other substances, so as not to affect the taste or flavor of heated cigarettes.

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

[0038] like Figure 1 As shown, the heated cigarette includes a filter section 1, a smoke-generating section 2, and a plug section 3 connected in sequence. The plug section 3 is formed from a paper base through multiple folds.

[0039] According to an embodiment of this utility model, by providing a plug section 3 at the end of the smoke-generating section 2 of the heated cigarette, the smoke-generating medium of the smoke-generating section 2 can be effectively prevented from falling off, and water, tar, and other substances can be effectively prevented from flowing into the heated cigarette device from the smoke-generating section 2. The plug section 3 is formed by multiple folds of paper base and is housed at the end of the heated cigarette. No adhesive or other substances need to be introduced, there is no odor during heating, and it will not affect the taste or flavor of the heated cigarette. Moreover, the manufacturing process is simple and the production efficiency is high. After the heated cigarette is smoked, no smoke-generating medium remains in the heated cigarette device, and the next cigarette can be smoked without cleaning, improving the experience. In addition, the outer paper tube of the heated cigarette is very clean after heating, without carbonization, tar leakage, or odor.

[0040] According to an embodiment of the present invention, the end cap 3 can be accommodated at the end of the cigarette paper of the smoke-generating section 2, or the end cap and the smoke-generating section 2 can be connected by the outer layer of cigarette paper.

[0041] According to an embodiment of this utility model, the direction of the paper base folding can be the axial direction of the end cap segment 3.

[0042] The heated cigarette provided in this embodiment can be adapted to both circumferentially heated and centrally heated tobacco devices. Heating methods for heated tobacco devices primarily utilize resistance heating, which is further divided into central and circumferential heating. Circumferential heating devices, due to heat radiating from the circumference to the center, improve the utilization rate of the cigarette, but suffer from higher heat loss and may produce a papery taste during heating, leading to a negative consumer experience. Centrally heated tobacco devices offer advantages such as a large heat transfer surface, high energy utilization, and high heating efficiency, and are the mainstream heating method for existing heated tobacco devices. However, they all suffer from common problems that urgently need to be addressed. For example, after the heated cigarette is smoked, the adhesion between the smoke-generating medium and the heating element 5 of the centrally heated tobacco device increases, making it impossible to directly remove the heated cigarette. Typically, a specific cigarette-removing structure within the centrally heated tobacco device is required to remove the heated cigarette.

[0043] According to embodiments of the present invention, such as Figure 2 As shown, the plug section 3 is configured to allow the heating element 5 of the centrally heated tobacco device to pass through. When the heated cigarette is pulled out from the heating element 5, the plug section 3 supports the smoke-generating section 2, causing the heated cigarette to detach from the heating element 5. Thus, the heated cigarette can be directly pulled out from the heating element 5 of the centrally heated tobacco device without the need for a specific smoke-removing structure in the centrally heated tobacco device.

[0044] After the heated cigarette is removed from the heating element 5 of the central heating device, the heating element 5 is usually covered with residue and tar, which can easily lead to damage or malfunction of the central heating device. In the embodiments of this utility model, such as... Figure 2 As shown, the plug section 3 is configured to allow the heating element 5 of the centrally heated cigarette to pass through and to clean the heating element 5 when it is pulled out. By placing the plug section 3 at the end of the smoke-generating section 2, the heating element 5 of the centrally heated cigarette can penetrate the plug section 3 and enter the smoke-generating section 2. After smoking, the heating element 5 can be directly pulled out of the heated cigarette. When pulled out, the plug section 3 can clean the residue and tar adhering to the heating element 5, reducing the contamination of the heating element 5 and improving the heating efficiency of the heating element 5.

[0045] According to an embodiment of this utility model, 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% to 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 a range consisting of any two of the above values. The plurality of holes penetrating both sides in the plug section 3 allow gas to flow smoothly into the heated cigarette when it is inhaled.

[0046] According to an embodiment of this utility model, the length of the plug section 3 can be 3-9 mm, optionally 3-5 mm. For example, 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 any range of two of the above values. If the plug section 3 is too short, it is easy for the plug section 3 to detach when the heating element 5 of the central heating device penetrates or is pulled out of the heated cigarette; if the plug section 3 is too long, the length of the smoke-generating section 2 is reduced, and the manufacturing cost increases.

[0047] According to embodiments of this invention, the basis weight of the paper base is 20~100 g / m³. 2 Optionally, the basis weight of the paper base can be 25~50 g / m³. 2 For example, the basis weight of the paper base can be 20 g / m³. 2 25g / m 2 30g / m 2 35g / m 2 40g / m 2 45g / m 2 50g / m 2 55g / m 2 60g / m 2 70g / m 2 80g / m 2 90g / m 2 100g / m 2 Or it can be a range consisting of any two of the above values.

[0048] According to embodiments of this invention, the paper base can be either a white cellulose paper base or a natural-colored cellulose paper base. The white cellulose paper base can be prepared using conventional methods: the paper base is produced from white pulp, which is a commercially available pulp, and the basis weight of the paper base can be 20~90 g / m³. 2 Preferably, it can be 25~50g / m 2 Unbleached cellulose paper base is prepared using conventional methods: it is produced from unbleached pulp, which is readily available commercial pulp—yellow wood pulp that has not undergone bleaching; no fillers are added during the paper base production process; the basis weight of the paper base can range from 10 to 60 g / m³. 2 Preferably, it can be 20~40g / m 2 .

[0049] According to an embodiment of this utility model, the length of the paper base can be equal to the length of the end cap section 3, and the width of the paper base can be 8~30cm. For example, the width of the paper base can be 8cm, 9cm, 10cm, 12cm, 15cm, 18cm, 20cm, 22cm, 25cm, 28cm, 30cm, or any range of two of the above values. Specifically, the paper base can be cut into widths of 8~30cm according to the design requirements of the end cap section 3. After being embossed by rollers, the paper base is pre-folded and shaped by two pairs of pressure rollers before entering the smoking gun. After exiting the double pressure rollers, the pre-folded embossed paper is pulled by a belt driven by a motor-driven pulley to reduce slippage. Simultaneously, the pulley applies pressure and fixes the folded embossed paper, thereby improving the uniformity and roundness of the pores. Finally, it is wrapped by the forming paper to form the end cap section 3.

[0050] According to an embodiment of this utility model, the paper base can be formed by interlacing fibers. The paper base can be embossed, and at the embossed areas, the fiber breakage rate can be 5% to 20%, placing the paper base in a state of being ready to be broken but not yet broken. Exemplarily, the fiber breakage rate can be 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, or a range of any two of the above values. When the heated cigarette is finished being smoked and directly pulled from the heating element 5 of the central heating device, the paper base in the ready-to-be-broken but not yet broken state can clean the heating element 5 through friction, preventing excessive friction from pulling out the end cap 3; furthermore, the paper base being in the ready-to-be-broken but not yet broken state increases the air permeability of the end cap 3, improving the smoking quality.

[0051] The depth of the embossing can be determined by the thickness of the paper base, ensuring that the paper base is in a state of being ready to be crushed but not yet crushed.

[0052] According to embodiments of this utility model, the embossing width of the embossed paper base can be 3~8mm. Exemplarily, the embossing width of the embossed paper base can be 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, or a range consisting of any two of the above values.

[0053] According to embodiments of this invention, a heat-resistant layer can be formed on one or both sides of the paper base through in-situ polymerization using silicone oil reagent. Exemplarily, the heat-resistant layer can be formed on one side of the paper base through in-situ polymerization using silicone oil reagent, or it can be formed on both sides of the paper base through in-situ polymerization using silicone oil reagent. The in-situ formed heat-resistant layer has good heat resistance and good stability under high-temperature environments, without decomposition or volatilization. It is beneficial for blocking heat conduction between the heating element 5 and the paper base, thereby improving the heat resistance of the paper base. Even when the central heating device is heated during cigarette smoking, the high temperature will not cause significant carbonization of the paper base. Furthermore, the heat-resistant layer formed by in-situ polymerization using silicone oil reagent is odorless when heated and will not affect the taste or flavor of the heated cigarette.

[0054] In some embodiments of this invention, silicone oil reagent can be coated on the surface of a paper base, and then the silicone oil reagent can be polymerized in situ to form a heat-resistant layer.

[0055] It should be noted that, in addition to amino silicone oil and / or vinyl silicone oil, the silicone oil reagent may also include a solvent to ensure that the amino silicone oil and / or vinyl silicone oil are uniformly coated on the surface of the paper base. For example, the silicone oil reagent may also include ethanol, and the volume ratio of amino silicone oil and / or vinyl silicone oil to ethanol in the silicone oil reagent may be 1:1 to 1:10.

[0056] Furthermore, the silicone oil reagent may also include a catalyst to catalyze the polymerization of amino silicone oil and / or vinyl silicone oil to form a heat-resistant layer.

[0057] According to embodiments of this invention, the heat-resistant layer has a unit area mass of 0.5~5.0 g / m² based on silicon. 2 A suitable mass per unit area can make end cap section 3 both temperature resistant and cost-effective.

[0058] According to an embodiment of the present invention, the in-situ polymerization temperature is 80℃~180℃. Exemplarily, the in-situ polymerization temperature can be 80℃, 90℃, 100℃, 110℃, 120℃, 130℃, 140℃, 150℃, 160℃, 170℃, 180℃, or a range of any two of the above values.

[0059] According to an embodiment of this utility model, the length of the smoke-generating section 2 can be 10~40mm, optionally 10~30mm, further optionally 10~15mm, and even more preferably 10~12mm. Exemplarily, the length of the smoke-generating section 2 can be 10mm, 12mm, 15mm, 18mm, 20mm, 22mm, 25mm, 28mm, 30mm, 32mm, 35mm, 38mm, 40mm, or a range consisting of any two of the above values.

[0060] According to an embodiment of the present invention, the smoke-generating section 2 can be configured as cigarette paper wrapping a smoke-generating medium, which can be a heat-release aerosol medium. Exemplarily, the smoke-generating medium may include at least one of reconstituted tobacco leaves, shredded tobacco, and tobacco particles.

[0061] According to embodiments of this utility model, the cigarette paper can be at least one of ordinary cigarette paper, aluminized cigarette paper, and impermeable cigarette paper. The basis weight of the ordinary cigarette paper can be 28-40 g / m³. 2 The air permeability can be 40~70CU. The basis weight of the aluminized paper can be 35~50g / m³. 2 The basis weight of impermeable cigarette paper can be 28~40 g / m³. 2 .

[0062] According to an embodiment of this utility model, the filter section 1 includes one or more of the following: a filtering section, a support end, a cooling section, and a fragrance-adding section.

[0064] According to an embodiment of this utility model, the length of the support segment can be 20-30mm, and optionally, the length of the support segment 2 can be 23-28mm. For example, the length of the support segment can be 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, 26mm, 27mm, 28mm, 29mm, 30mm, or a range consisting of any two of the above values.

[0065] The paper base used in the paper-based filter rod can be at least one of cellulose paper, tallow paper, forming paper, and tracing paper. One or both sides of the paper base can be coated with at least one of cooling material and fragrance material.

Before entering the cigarette gun, the paper base is pre-folded and formed step by step by two pairs of pressure rollers. After the pre-folded embossed paper exits the double pressure rollers, a belt driven by a motor pulley pulls the folded pre-embossed paper to a certain extent to reduce slippage. At the same time, the pulley squeezes and fixes the folded embossed paper to a certain extent, thereby improving the uniformity and roundness of the pores. Finally, it is wrapped by the forming paper to form the plug section.
