Description

Technical Field

[0001] The present invention relates to the technical field of heated cigarettes, and in particular to a heated cigarette. Background Art

[0002] Heated cigarettes release smoke through a non-combustion heating method, replacing the traditional combustion-induced pyrolysis process. Heating temperatures range from 200-350°C, producing significantly fewer harmful substances than traditional cigarettes. In today's era of promoting health, new tobacco products like heated cigarettes have become a major research focus in the tobacco industry.

[0003] Current heated cigarettes are primarily categorized by the shape of the smoke-generating thin slices: ordered and random. For ordered heated cigarettes, the relatively low porosity affects the heating efficiency of the heated tobacco device. In the case of inner-core heated tobacco devices, heat is concentrated near the heating needles, with less diffusion to the periphery. On the other hand, when inserted into an inner-core heated tobacco device, ordered heated cigarettes can also experience the thin slices being pushed outside the smoke-generating section by the heating needles, which also affects heat diffusion efficiency. While random heated cigarettes have a higher porosity and more even heat distribution, their unordered thin slices are relatively difficult to roll and are prone to falling off the end of the cigarette, impacting the smoking experience.

[0004] Therefore, there is a need for a heated cigarette. Summary of the Invention

[0005] The object of the present invention is to provide a heated cigarette to solve the above-mentioned problems in the prior art, and to improve the porosity and heat diffusion efficiency while maintaining the continuity of the sheet.

[0006] The present invention provides a heated cigarette, comprising:

[0007] A smoking segment and a filtering segment, wherein the smoking segment is rolled from reconstituted tobacco leaf sheets, the reconstituted tobacco leaf sheets include one whole sheet or multiple reconstituted tobacco leaf sheets, and each of the reconstituted tobacco leaf sheets has a plurality of uncut complete foldable and / or curlable shear marks.

[0008] In the heated cigarette as described above, preferably, the shear mark consists of one or more curves, or the shear mark consists of multiple straight lines.

[0009] In the heated cigarette as described above, preferably, the shear mark has a U-shape or a C-shape.

[0010] In the heated cigarette as described above, preferably, the length of the shear mark is less than twice the length of the smoking section, and the width of the shear mark is less than the width of the reconstituted tobacco leaf sheet.

[0011] In the heated cigarette as described above, preferably, the length of the shear mark is between 2 mm and 50 mm, and the width of the shear mark is between 0.3 mm and 10 mm.

[0012] In the heated cigarette as described above, preferably, a single shear mark is located at any position on a reconstituted tobacco leaf sheet, a plurality of the shear marks are arranged in a single layer or multiple layers, and a plurality of the shear marks are arranged in a straight line, staggered or randomly distributed.

[0013] As described above, in the heated cigarette, preferably, when the reconstituted tobacco leaf sheet with shear marks is rolled into the smoking segment, the rolling direction of the reconstituted tobacco leaf sheet satisfies the requirement that the area without the shear marks is rolled facing outwards.

[0014] In the heated cigarette as described above, preferably, the shear marks are shear marks that have been processed mechanically, and / or vacuumed, and / or wind-forced, so that the shear marks are separated from the reconstituted tobacco leaf sheet and each of the shear marks can be wrinkled and / or curled.

[0015] In the heated cigarette as described above, preferably, the smoking segment further comprises powder produced during processing on the reconstituted tobacco leaf sheet.

[0016] The present invention provides a heated cigarette, which maintains the continuity of the thin slices through shear marks, is easy to produce and is not prone to end thread falling. In addition, the shear marks can be wrinkled and / or curled, which can increase the porosity of the reconstituted tobacco leaf slices, thereby increasing the heat transfer efficiency of the smoking section, and comprehensively improving the product quality and smoking experience. By crushing, the porosity of the reconstituted tobacco leaf slices can be further increased, thereby increasing the heat transfer efficiency of the smoking section, and comprehensively improving the product quality and smoking experience.

[0032] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. The description of the exemplary embodiments is merely illustrative and is in no way intended to limit the present disclosure, its application, or use. The present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to make the present disclosure thorough and complete and to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that unless otherwise specifically stated, the relative arrangement of parts and steps, the composition of materials, numerical expressions, and numerical values ​​set forth in these embodiments should be interpreted as being merely exemplary and not as limiting.

[0034] In the present disclosure, when a specific component is described as being located between a first component and a second component, there may or may not be an intervening component between the specific component and the first component or the second component. When a specific component is described as being connected to another component, the specific component may be directly connected to the other component without an intervening component, or may not be directly connected to the other component but have an intervening component.

[0035] All terms (including technical or scientific terms) used in this disclosure have the same meaning as those understood by one of ordinary skill in the art to which this disclosure belongs, unless otherwise specifically defined. It should also be understood that terms defined in, for example, general dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an idealized or highly formal sense, unless explicitly defined herein.

[0036] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0037] like Figure 1-Figure 5 As shown, an embodiment of the present invention provides a heated cigarette, which includes: a smoking section 32 and a filtering section 31, wherein the smoking section 32 is made of reconstituted tobacco leaf sheets, and the reconstituted tobacco leaf sheets include one or more reconstituted tobacco leaf sheets 11, and each reconstituted tobacco leaf sheet 11 has a plurality of uncut complete foldable and / or curlable shear marks 17 (such as Figure 2 shown).

[0038] The filter section 31 may be composed of a single component or a combination of multiple components. The components may be one or more components that perform functions such as flue gas cooling, flue gas filtration, support, and fragrance supplementation. It should be noted that the present invention does not impose specific limitations on the materials and internal structures of the components.

[0039] The distribution position of the shearing trace 17 satisfies that when shearing the cigarette rod subsequently, the reconstituted tobacco sheet will not be divided into two independent parts. On the premise of meeting this condition, the reconstituted tobacco sheet is sheared to obtain the shearing trace. In a specific implementation, the shearing trace 17 can be formed by pressing with a pressing roller.

[0040] For a single reconstituted tobacco sheet, the shearing process can form only 1 shearing trace 17, or can form multiple shearing traces 17. The present invention does not make specific limitations on this.

[0041] Furthermore, for any reconstituted tobacco sheet, the shape of the shearing trace 17 can be various. In some embodiments of the present invention, the shearing trace is composed of one or more curves. Preferably, the shape of the shearing trace is U-shaped or ∪-shaped. In other embodiments of the present invention, the shearing trace is composed of multiple straight lines. Preferably, the shape of the shearing trace is ∪-shaped. Further, a single shearing trace is located at any position of a reconstituted tobacco sheet, and several shearing traces are arranged in a single layer or multiple layers, and several shearing traces are arranged in a straight line, staggered arrangement or random distribution.

[0042] As Figure 3-Figure 5 shown, the large square represents a reconstituted tobacco sheet 11, and the black line inside the square represents the shearing trace. Figure 3 shows the U-shaped shearing traces 12 arranged in a straight line. Figure 4 shows the ∪-shaped shearing traces 13 arranged in a staggered manner. Figure 5 shows the U-shaped shearing traces 12 and ∪-shaped shearing traces 13 arranged randomly. It should be noted that the present invention does not make specific limitations on the shape, quantity and relative position relationship of the shearing traces.

[0043] Furthermore, the size of the shear mark should be sufficient to avoid causing additional breakage of the reconstituted tobacco leaf sheet during subsequent processing. After a series of processes, such as roller processing to create the shear mark and forming wrinkles, the reconstituted tobacco leaf sheet is rolled into a sheet base rod, which is then cut and compounded one or more times to form a finished cigarette. This requires cutting the sheet base rod into shorter segments. Aside from any necessary breakage of the reconstituted tobacco leaf sheet during this process, the size of the shear mark should not cause additional breakage due to cutting, thereby disrupting the continuity of the reconstituted tobacco leaf sheet. Specifically, the overall length of the shear mark 17 is less than twice the length of the smoking segment 32, and the overall length of the shear mark 17 is between 2 mm and 50 mm, preferably between 3 mm and 7 mm, for example, 5 mm. Furthermore, the overall width of the shear mark 17 is less than the maximum width of the reconstituted tobacco leaf sheet 11. The overall horizontal length of the shear mark 17 in the cigarette is between 0.3 mm and 10 mm, preferably between 0.5 mm and 2 mm, for example, 1 mm. It should be noted that the present invention does not impose specific restrictions on the length of the shear mark in the radial and transverse directions of the entire cigarette. For irregularly shaped curved shear marks, the projection of the shear mark on a plane is obtained when the reconstituted tobacco leaf sheet is laid flat. On the premise that the projection is entirely contained within a plane, many rectangles can be drawn on the plane. It is obvious that there is a minimum drawing method among these rectangles. The length and width of the rectangle drawn using the minimum drawing method are defined as the length and width of the irregularly shaped shear mark. Therefore, for irregularly shaped curved shear marks, the length and width of the shear mark are determined by the smallest rectangle that can completely enclose the projection of the shear mark on the plane.

[0044] Figure 6 The irregular shear mark projection 14 is shown. The rectangle in the figure is the smallest rectangle that can contain the irregular shear mark projection 14. Figure 6 The first minimum rectangle 21 surrounding the irregular shear mark projection 14 is also shown. The length and width of this irregular mark are Figure 6 The length and width of the first minimum rectangle 21. Figure 7 The straight line broken line shear mark projection 15, the arc curve shear mark projection 16, the second smallest rectangle 22 surrounding the straight line broken line shear mark projection 15 and the third smallest rectangle 23 surrounding the arc curve shear mark projection 16 are shown. The length and width of the straight line broken line shear mark projection 15 are Figure 7 The length and width of the second smallest rectangle 22 and the length and width of the arc shear mark projection 16 are Figure 7 The length and width of the third smallest rectangle 23.

[0045] Furthermore, if Figure 6As shown, the shear marks are shear marks that have been processed mechanically, and / or vacuum, and / or wind-forced, so that the shear marks can be wrinkled and / or curled. In a specific implementation, the shear marks are subjected to additional processing to achieve wrinkling or curling of the sheared portion, so that the sheared portion leaves the reconstituted tobacco leaf sheet, and partial separation between the sheared portion and the sheet is achieved. Among them, the processing method can be to introduce a mechanical structure to perform external force processing on the shear marks, or to introduce a vacuum device to suck, or to introduce wind to blow. In a specific implementation, the process of mechanical and / or vacuum, and / or wind-force processing can be performed before applying the shear marks, or it can be performed after applying the shear marks, and the present invention does not limit this.

[0046] Furthermore, when the reconstituted tobacco leaf sheet having shear marks is rolled into the smoking segment, the reconstituted tobacco leaf sheet is rolled in a direction such that the area without the shear marks faces outward. In other embodiments of the present invention, the reconstituted tobacco leaf sheet can be rolled in any direction, and this is not specifically limited by the present invention.

[0047] Furthermore, the smoking section also includes fines generated when shear marks are applied to the reconstituted tobacco leaf sheets. These fines, mixed between the sheets, can affect the airflow path, causing airflow disturbances and turbulence, thereby improving heat transfer efficiency. In other embodiments of the present invention, the fines generated when shear marks are applied can be selectively rolled into cigarettes without being included in the reconstituted tobacco leaf sheets. That is, the fines generated when shear marks are applied can be selectively rolled into cigarettes with the reconstituted tobacco leaf sheets.

[0048] Furthermore, when the reconstituted tobacco leaf sheet with shear marks is rolled into the smoking section, the reconstituted tobacco leaf sheet is rolled in a direction such that the area without the shear marks faces outward. This ensures that when the heated cigarette is inserted into the inner core heating device, the unsheared portion first contacts the heating needle 33. If the heating needle 33 is inserted from the bottom end to the top end of the U-shape, the raised sheet will block the heating needle; conversely, if the heating needle is inserted from the top end to the bottom end of the U-shape, the raised sheet will not block the heating needle. Moreover, since the sheet is a continuous whole, the sheet will not be pushed out of the smoking section.

[0049] Therefore, compared with the prior art, the embodiment of the present invention provides a heated cigarette, which maintains the continuity of the thin sheet through shear marks, is easy to produce and is not prone to end thread falling, and the shear marks can be wrinkled and / or curled, which can increase the porosity of the reconstituted tobacco leaf sheet, thereby increasing the heat transfer efficiency of the smoking section, and comprehensively improving the product quality and smoking experience; through crushing, the porosity of the reconstituted tobacco leaf sheet can be further increased, thereby increasing the heat transfer efficiency of the smoking section, and comprehensively improving the product quality and smoking experience.
