Abstract: The present disclosure comprises a plurality of scent diffusion cartridge main body units configured to generate different scents, a mounting recognition unit comprising a plurality of mounting regions in which the scent diffusion cartridge main body unit is mounted, configured to detect whether the scent diffusion cartridge main body unit is mounted in the mounting region, and a control unit configured to determine whether the scent diffusion cartridge main body unit is mounted in the mounting region from the mounting recognition unit, and control a scent of the scent diffusion cartridge main body unit mounted in another mounting region to be selectively diffused as the scent diffusion cartridge main body unit is dismounted from the mounting region.

Abstract: A vehicle includes a perfume diffuser including a pair of electrodes, at least one fragrance cartridge including a resistance plate electrically connected to the pair of electrodes, and a controller identifying the types of the fragrance cartridge based on the size of current flowing through the pair of electrodes and the resistance plate.

Abstract: Disclosed herein is an air vent device, the air vent device including a garnish including an opening in which an air vent hole is located, a grille unit located between an outer surface of the air vent hole and an inner surface of the garnish, a first wing located at an outer side of the air vent hole in a lateral direction and configured to be pivoted based on one end of the grille unit, a deco part located on an outer surface of the garnish, and a knob configured to control a direction of a wind discharged from the air vent hole, wherein the knob is located to surround a portion of the deco part and configured to be capable of controlling a direction of a wind in a vertical direction by operating the first wing.

Abstract: A fragrance diffuser for a vehicle has a structure separate from an air conditioning operation of a vehicle and may selectively emit a fragrance stored in a plurality of cartridges by an opening/closing device. The fragrance diffuser includes: a plurality of cartridges each including: a casing having an internal space configured to store a fragrance; and an opening/closing member extending to communicate with an interior and an exterior of the casing, and configured to open or close the internal space; a housing including: an inlet; a movement passage for the air; insertion ports into which the cartridges are inserted in the movement passage; and an outlet from which the fragrance or the air is discharged depending on an opened or closed state of each of the cartridges; an opening/closing device configured to operate the opening/closing members; and a control unit configured to control an operation of the opening/closing device.
