Description

CROSS REFERENCE TO RELATED APPLICATIONS This application is a National Stage of International Application No. PCT/KR2022/012010 filed Aug. 11, 2022, claiming priority based on Korean Patent Application No. 10-2021-0106935 filed Aug. 12, 2021 and Korean Patent Application No. 10-2021-0132689 filed Oct. 6, 2021. TECHNICAL FIELD The disclosure relates to an aerosol generating device including a cartridge, and more particularly, to an aerosol generating device including a cartridge provided with a movable mouthpiece. BACKGROUND ART In recent years, there has been an increasing demand for an alternative method that overcomes the disadvantages of conventional cigarettes. For example, there is growing demand for an aerosol generating device which generates aerosols by heating an aerosol generating material, rather than by combustion of cigarettes. Accordingly, research on a heating-type aerosol generating device have been actively conducted. A heating-type aerosol generating device may include, for example, a cartridge that stores an aerosol generating material in a liquid or gel state and atomizes the stored aerosol generating material. The cartridge may be provided with a mouthpiece for a user to inhale through the aerosol generating device. DISCLOSURE OF INVENTION Technical Problem The mouthpiece protruding from the aerosol generating device may increase the size and reduce the portability of the aerosol generating device. Thus, there is a need for an aerosol generating device including a cartridge that is designed to improve convenience of the user. Objects to be achieved by the embodiments are not limited to the above-described objects, and objects not described may be clearly understood by those skilled in the art to which the embodiments belong from the present specification and the accompanying drawings.
