Description

Aerosol generating device and stick accommodated therein The following embodiments relate to an aerosol generating device and a stick housed therein. Recently, there has been an increasing demand for alternative products that overcome the disadvantages of traditional cigarettes. For example, there is an increasing demand for devices that generate aerosols by electrically heating a cigarette stick (e.g., heated tobacco products). Accordingly, research on electric heating aerosol generating devices and cigarette sticks (or aerosol generating products) applied thereto is actively underway. For example, Korean Patent Publication No. 10-2017-0132823 discloses a non-combustion type flavor inhaler, a flavor inhalation source unit, and an atomization unit. FIG. 1 is a block diagram of an aerosol generating device according to one embodiment. FIG. 2a is a drawing illustrating an example in which a stick is inserted into an aerosol generating device according to one embodiment. FIG. 2b is a drawing illustrating an example in which a stick is inserted into an aerosol generating device according to one embodiment. FIG. 3 is an exploded view of an aerosol generating device according to one embodiment. FIG. 4a is a perspective view of a cartridge according to one embodiment. FIG. 4b is a cross-sectional view of a cartridge according to one embodiment. FIG. 5 is a schematic perspective view of a stick according to one embodiment. FIG. 6 is a cross-sectional view of the second filter segment of a stick 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, the applicant has arbitrarily selected terms, 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. As used herein, when an expression such as "at least one" precedes an arranged component, it modifies the entire set of components rather than each individual component. For example, the expression "at least one of a, b, and c" should be interpreted as including a, b, and c, or a and b, a and c, b and c, or a, b, and c. In the following embodiments, "stick" may refer to an article that contains a medium, through which an aerosol passes and the medium is transferred. Representative examples of a stick may include cigarettes, but the scope of the present disclosure is not limited thereto. In the following embodiments, "upstream" or "upstream direction" may mean a direction away from the user's (smoker's) bend, and "downstream" or "downstream direction" may mean a direction closer to the user's bend. The terms upstream and downstream may be used to describe the relative positions of the elements constituting the stick. In the following embodiments, "puff" refers to the user's inhalation, and inhalation refers to a situation in which something is drawn into the user's oral cavity, nasal cavity, or lungs through the user's mouth or nose. In one embodiment, the aerosol generating device may be a device that generates an aerosol by electrically heating a stick contained in an internal space. The aerosol generating device may include a heater. In one embodiment, the heater may be an electric resistive heater. For example, the heater may include an electric conductive track, and the heater may be heated when current flows through the electric conductive track. The heater may include a tubular heating element, a plate heating element, a needle heating element, or a rod heating element, and may heat the inside or outside of the stick depending on the shape of the heating element. The stick may include a tobacco rod and a filter rod. The tobacco rod may be made of a sheet, a strand, or finely cut tobacco. Additionally, the tobacco rod may be surrounded by a heat-conducting material. For example, the heat-conducting material may be a metal foil, such as aluminum foil, but is not limited thereto. The filter rod may be a cellulose acetate filter. The filter rod may be composed of at least one segment. For example, the filter rod may include a first segment for cooling the aerosol and a second segment for filtering a certain component contained
