Technical Field

[0001] The present invention relates to the field of heated cigarette manufacturing, and more specifically, to a fully separated heated cigarette for paperless heating. Background Art

[0002] Traditional cigarettes release nicotine and flavor by directly burning tobacco to meet the needs of consumers. Tobacco will release many harmful substances during the high-temperature decomposition process. In recent years, as people's health awareness has increased, in order to avoid inhaling harmful substances released by high-temperature decomposition of tobacco, heat-not-burn cigarettes have emerged.

[0003] Heat-not-burn cigarettes use a matching external heat source to heat tobacco, obtaining nicotine and flavor without burning it. While meeting consumers' smoking needs, they have the characteristics of reducing tar and reducing harm compared to traditional cigarettes.

[0004] The tobacco segments of existing heat-not-burn cigarettes are wrapped in cigarette paper and inserted into a heating chamber of a smoking device for heating. When heated, the cigarette paper will produce a strong paper smell that mixes into the smoke and affects the purity of the smoke, thereby affecting the smoking experience of consumers.

[0005] Therefore, how to provide a heated cigarette that can effectively prevent the smell of cigarette paper from affecting the purity of smoke has become a technical problem that urgently needs to be solved in this field. Summary of the invention

[0006] An object of the present invention is to provide a new technical solution for fully separated heating of cigarettes for paperless heating, which can effectively prevent the paper smell of cigarette paper from affecting the smoke purity.

[0007] According to a first aspect of the present invention, a fully-separated heated cigarette stick for paperless heating is provided.

[0008] The fully separated heated cigarette for paperless heating comprises a tobacco segment, a tobacco segment wrapper, a cooling segment, a filter segment, a first composite wrapper and a second composite wrapper; wherein:

DETAILED DESCRIPTION

[0031] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0032] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0033] 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 as part of the specification.

[0034] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0035] like Figures 1 to 4 As shown, the fully separated heated cigarette for paperless heating disclosed in the present invention includes a tobacco segment 1, a tobacco segment wrapper 2, a cooling segment, a filter segment 5, a first composite wrapper 6 and a second composite wrapper 7.

[0036] The tobacco segment 1, the cooling segment and the filter segment 5 are arranged in sequence. In specific implementation, the tobacco segment 1 and the cooling segment are only in contact but not bonded to ensure that the tobacco segment 1 and the cooling segment can be separated when the cigarette is heated for use. The cooling segment and the filter segment 5 can be only in contact but not bonded, and the cooling segment and the filter segment 5 can be compounded together by the wrapping action of the first composite wrapper 6 and the second composite wrapper 7; or, the end faces of the cooling segment and the filter segment 5 can be bonded together. The cooling segment can be implemented in a variety of ways, for example, a cooling channel extending along the length direction of the cooling segment is provided in the cooling segment; for another example, the cooling segment has a honeycomb structure.

[0037] The tobacco segment wrapper 2 can be used to wrap the tobacco segment 1, and the tobacco segment 1 is completely wrapped in the tobacco segment wrapper 2. The first composite wrapper 6 can be used to wrap the cooling segment and the filter segment 5. The second composite wrapper 7 can be used to wrap the filter segment 5 and part of the cooling segment.

[0038] The tobacco segment wrapper 2 is provided with a first air inlet groove 20 extending along the length direction of the tobacco segment wrapper 2, and the tobacco segment wrapper 2 is sleeved outside the first composite wrapper 6 and slidably cooperates with the first composite wrapper 6. The first air inlet groove 20 can form an air inlet channel. The slidable cooperation between the tobacco segment wrapper 2 and the first composite wrapper 6 allows the tobacco segment wrapper 2 to slide along the outer wall of the first composite wrapper 6, thereby exposing the tobacco segment 1 wrapped in the tobacco segment wrapper 2.

[0039] The second composite wrapping member 7 is sleeved outside the first composite wrapping member 6. The sum of the length of the tobacco segment wrapping member 2 and the length of the second composite wrapping member 7 is less than or equal to the length of the first composite wrapping member 6. When the tobacco segment wrapping member 2 slides along the outer wall of the first composite wrapping member 6 until it abuts against the second composite wrapping member 7, the tobacco segment wrapping member 2 is completely separated from the tobacco segment 1, and the tobacco segment 1 can be separated from the heated cigarette.

[0040] The use process of the fully separated heating cigarette for paperless heating disclosed in the present invention can be as follows:

[0041] When the heated cigarette is not inserted into the smoking device, the tobacco segment wrapper 2 wraps the tobacco segment 1, the first composite wrapper 6 and the second composite wrapper 7 wrap the cooling segment and the filter segment 5, and the tobacco segment 1 is composited with the cooling segment and the filter segment 5 through the socket connection between the tobacco segment wrapper 2 and the first composite wrapper 6 to form a complete heated cigarette.

[0042] When the heated cigarette is inserted into the smoking device to a certain depth, the tobacco segment wrapper 2 stops moving due to the force of the smoking device, and the tobacco segment 1 continues to be pushed toward the heating chamber of the smoking device under the push of the cooling section and the filter section 5, and the tobacco segment wrapper 2 moves along the outer wall of the first composite wrapper 6 in a direction away from the tobacco segment 1. As the tobacco segment wrapper 2 moves along the outer wall of the first composite wrapper 6, the tobacco segment 1 and the tobacco segment wrapper 2 gradually separate until the tobacco segment wrapper 2 abuts against the second composite wrapper 6, at which time the tobacco segment wrapper 2 is completely separated from the tobacco segment 1 (such as Figure 5 As shown in FIG. 1 , the tobacco segment 1 can be completely separated from the heated cigarette. The first air inlet groove 20 can be used as an air inlet channel when the heated cigarette is smoked.

[0043] After the heated cigarette of the present disclosure is inserted into the smoking device, the tobacco segment wrapper 2 can slide along the first composite wrapper 6 until the tobacco segment wrapper 2 and the tobacco segment 1 are completely separated, at which time the tobacco segment 1 is separated from the heated cigarette and falls into the heating chamber of the smoking device, thereby achieving paperless heating of the tobacco segment 1 during the heating process, eliminating the influence of paper smell on smoke, and greatly improving the smoking experience. Moreover, the provision of the first air intake groove 20 can achieve the purpose of not needing to provide an air intake channel on the smoking device, effectively reducing the cost of the smoking device and improving the smoking experience.

[0044] In one embodiment of the fully separated heated cigarette for paperless heating disclosed herein, in order to reduce the resistance of the tobacco segment wrapper 2 to the movement of the tobacco segment 1, the end of the tobacco segment wrapper 2 is flush with the free end of the tobacco segment 1.

[0045] In one embodiment of the fully separated heated cigarette for paperless heating disclosed herein, a second air intake groove 10 extending along the length direction of the tobacco segment 1 is provided on the tobacco segment 1. The provision of the second air intake groove 10 is conducive to improving the air intake effect, thereby achieving a better smoking experience.

[0046] Furthermore, the first air intake grooves 20 are evenly distributed along the circumferential direction of the tobacco segment wrapper 2, and the second air intake grooves 10 are evenly distributed along the circumferential direction of the tobacco segment 1, and the first air intake grooves 20 and the second air intake grooves 10 are arranged one by one. In this way, when the tobacco segment 1 is completely separated from the tobacco segment wrapper 2, the first air intake grooves 20 and the second air intake grooves 10 are connected to form an air intake channel with smooth airflow, thereby further improving the air intake effect.

[0047] In specific implementation, the first air intake groove 20 can be formed by applying pressure to the tobacco segment wrapper 2. Since the tobacco segment 1 is wrapped by the tobacco segment wrapper 2, when the tobacco segment wrapper 2 is subjected to force, the tobacco segment 1 is also subjected to pressure, thereby forming the second air intake groove 10 on the tobacco segment 1.

[0048] In one embodiment of the fully separated heated cigarette for paperless heating disclosed in the present invention, in order to improve the compactness of the heated cigarette structure, the sum of the length of the tobacco segment wrapper 2 and the length of the second composite wrapper 7 is equal to the length of the first composite wrapper 6, and the end of the first composite wrapper 6 and the end of the second composite wrapper 7 are flush with the free end of the filter segment 5. When the heated cigarette is inserted into the smoking device, the tobacco segment wrapper 2 moves along the first composite wrapper 6 until it abuts against the second composite wrapper 7, at which time the end of the tobacco segment wrapper 2 away from the second composite wrapper 7 is flush with the end of the first composite wrapper 6 adjacent to the tobacco segment 1, and the tobacco segment 1 and the tobacco segment wrapper 2 are completely separated.

[0049] In one embodiment of the fully separated heated cigarette for paperless heating disclosed herein, the cooling section includes a first cooling section 3 and a second cooling section 4 , and the second cooling section 4 is located between the first cooling section 3 and the filter section 5 .

[0050] In specific implementation, the second cooling segment 4 may only be in contact with the first cooling segment 3 and the filter segment 5 without being bonded, and the first cooling segment 3, the second cooling segment 4 and the filter segment 5 may be bonded together by the wrapping action of the first composite wrapping member 6 and the second composite wrapping member 7; or the second cooling segment 4 may be bonded together with the end faces of the first cooling segment 3 and the filter segment 5. In addition, the first composite wrapping member 6 may wrap the first cooling segment 3, the second cooling segment 4 and the filter segment 5, and the second composite wrapping member 7 may wrap the second cooling segment 4 and the filter segment 5.

[0051] A first cooling channel 30 is provided in the first cooling section 3, and a second cooling channel 40 is provided in the second cooling section 4. The inner diameter of the first cooling channel 30 is smaller than the inner diameter of the second cooling channel 40. The setting of the inner diameters of the first cooling channel 30 and the second cooling channel 40 is conducive to improving the cooling effect.

[0052] Furthermore, the outer diameter of the first cooling section 3 is equal to the outer diameter of the second cooling section 4 .

[0053] Furthermore, in order to more effectively improve the cooling effect, the length of the first cooling section 3 is greater than the length of the second cooling section 4 .

[0054] Furthermore, in order to more effectively improve the cooling effect, the length of the first cooling section 3 is 1.5-2 times the length of the second cooling section 4.

[0055] Furthermore, in order to more effectively improve the cooling effect, the ratio of the inner diameter of the first cooling channel 30 to the inner diameter of the second cooling channel 40 is (3-4):(4-5.5).

[0056] Although some specific embodiments of the present invention have been described in detail by way of example, it will be appreciated by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It will be appreciated by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
