The present invention is applicable to the field of cosmetic instruments. The present invention discloses a nozzle rotating mechanism and a facial steaming apparatus, wherein the nozzle rotating mechanism comprises a nozzle and a driving mechanism for rotating the nozzle, the nozzle being located outside an axis of a nozzle shaft, the axis of the nozzle being parallel to or forming an angle with the nozzle shaft. The nozzle rotating mechanism is driven to rotate by a driving mechanism when it is in use. Since the axis of the nozzle is parallel to or forming an angle with the nozzle shaft, i.e., the axis of the nozzle and the nozzle shaft are not on the same line, so the nozzle must form a larger radius of rotation relative to the axis of the nozzle shaft when the nozzle rotates on the nozzle shaft. Therefore, the nozzle can form a larger area, which can increase the area of steam injection, better suit requirements from different users, and improve the user experience. At the same time, the structure is simple, compact, stable and reliable. The nozzle rotating mechanism is widely used in steam cleaning devices for facial steaming apparatuses.
