The optical device unit 120 inputs an electrical signal according to the amount of light received by the light receiving unit to the microcontroller 130, and the microcontroller 130 transmits the liquid cartridge 110 according to the signal input from the optical device unit 120. Recognizes the remaining amount of liquid. Referring to (b) of FIG. 3, according to the embodiment, the prism member 111 is installed on the side of the liquid cartridge 110. For example, when the liquid cartridge 110 is positioned in a horizontal state or tilted close to the horizontal state, a structure in which the prism member 111 is installed on the side of the liquid cartridge 110 may more accurately recognize the remaining amount of liquid. The prism member 111 may have an inclined surface as shown in (a) and (b) of FIG. 3, and referring to (c) of FIG. 3, according to the embodiment, the prism member 111 is provided with a curved surface. You may. According to an embodiment, the optical device unit 120 emits light of a specific color. When the optical device unit 120 irradiates light of a specific color, the generally transparent liquid phase is discolored by the light of a specific color emitted from the optical element unit 120, so that the user recognizes the amount of liquid remaining with the naked eye. can do. According to an embodiment, the liquid cartridge remaining amount recognizing device 100 further includes a display unit 140, and the microcontroller 130 determines the remaining liquid amount of the liquid cartridge 110 according to a signal input from the optical device unit 120. Recognized and controls the display unit 140 to display information on the amount of liquid remaining. Therefore, the user can recognize the amount of liquid remaining through the display unit 140 . In addition, according to the embodiment, the liquid cartridge remaining amount recognizing device 100 includes a power supply unit 150 for turning on-off power of an aerosol generating device to which the liquid cartridge remaining amount recognizing device 100 is applied, and The controller 130 recognizes the remaining amount of liquid in the liquid cartridge 110 according to a signal input from the optical element unit 120, and when it is determined that the remaining amount of liquid is less than the standard remaining amount, for example, in an exhausted state, the power supply unit 150 The power can be turned off by controlling.
