  4. In Article 1, A cigarette, wherein each of the above plurality of segments is a tubular filter of a different shape.
  5. In Article 1, A cigarette, wherein each of the plurality of segments is a tubular filter containing a different hollow.
  6. In Article 1, A cigarette in which the diameter of each of the plurality of perforations is 0.02 mm to 0.08 mm.
  7. In Article 1, The above wrapper includes an inner wrapper and an outer wrapper surrounding the inner wrapper, and A cigarette, wherein the plurality of perforations are formed along the outer surface of the outer wrapper.
  8. In Article 1, A cigarette, wherein the plurality of perforations are formed along the circumferential direction of the wrapper.
  9. A housing having a receiving space formed therein into which a cigarette according to any one of claims 1 to 8 can be inserted; An induction coil that forms a magnetic field within the above receiving space; and An aerosol generating device comprising a control unit electrically connected to the induction coil and controlling the supply of battery power to the induction coil.
  10. An aerosol generating device having a first receiving space formed therein into which a cigarette according to any one of claims 1 to 8 can be inserted; and An aerosol generating system comprising a cradle having a second receiving space formed therein in which the above-mentioned aerosol generating device can be accommodated.

Description

Cigarette and aerosol generating apparatus therefor One or more embodiments relate to cigarettes and aerosol generating devices for cigarettes, and more specifically, to cigarettes and aerosol generating devices for cigarettes that include perforations to allow air to be introduced into the interior. Recently, there has been an increasing demand for alternative methods to overcome the disadvantages of conventional cigarettes. For example, there is a growing demand for methods in which aerosols are generated as an aerosol-generating substance within the cigarette is heated, rather than methods that generate aerosols by burning the cigarette. Accordingly, research on heated cigarettes or heated aerosol-generating devices is actively underway. FIGS. 1 to 3 are drawings illustrating examples in which a cigarette is inserted into an aerosol generating device. FIG. 4 is a drawing illustrating a cigarette according to one embodiment. FIG. 5 is a drawing illustrating a cigarette with perforations formed therein according to one embodiment. FIG. 6 is a longitudinal cross-sectional view of a cigarette illustrating the flow of air passing through the cigarette according to one embodiment. FIG. 7 is a longitudinal cross-sectional view of a cigarette illustrating the flow of air passing through the cigarette according to one embodiment. FIG. 8 is a diagram showing points where the temperature of the main smoke and the surface temperature of the cigarette were measured in a cigarette according to one embodiment. The terms used in the embodiments have been selected to be as widely used as possible, taking into account their functions in the present invention; however, these terms may vary depending on the intent of those skilled in the art, case law, the emergence of new technologies, etc. Additionally, in specific cases, terms have been arbitrarily selected by the applicant, and in such cases, their meanings will be described in detail in the relevant description of the invention. Therefore, the terms used in the present invention should be defined not merely by their names, but based on their meanings and the overall content of the invention. When a part of a specification is described as "including" a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components. Furthermore, terms such as "part" or "module" as used in the specification refer to a unit that processes at least one function or operation, and this may be implemented in hardware or software, or as a combination of hardware and software. Throughout the specification, "aerosol generating article" may refer to a substance capable of generating an aerosol, such as tobacco (cigars), cigars, etc. An aerosol generating article may include an aerosol generating substance or an aerosol-forming substrate. Additionally, an aerosol generating article may include a solid material based on tobacco raw materials, such as sheet tobacco, cut tobacco, or reconstituted tobacco. The aerosol may include volatile compounds. Additionally, throughout the specification, "upstream" or "forward" refers to the direction away from the user's mouth where the aerosol-generating item is being smoked, and "downstream" or "rear" refers to the direction towards the user's mouth where the aerosol-generating item is being smoked. Embodiments of the present invention are described below with reference to the attached drawings so that those skilled in the art can easily implement them. However, the present invention may be embodied in various different forms and is not limited to the embodiments described herein. Embodiments of the present invention will be described in detail below with reference to the drawings. FIGS. 1 to 3 are drawings illustrating examples in which a cigarette is inserted into an aerosol generating device. Referring to FIG. 1, the aerosol generating device (1) includes a battery (11), a control unit (12), and a heater (13). Referring to FIG. 2 and FIG. 3, the aerosol generating device (1) further includes a vaporizer (14). Additionally, a cigarette (3) may be inserted into the internal space of the aerosol generating device (1). The aerosol generating device (1) illustrated in FIGS. 1 to 3 includes components related to the present embodiment. Therefore, it can be understood by those skilled in the art related to the present embodiment that other general-purpose components may be included in the aerosol generating device (1) in addition to the components illustrated in FIGS. 1 to 3.
