US Patent 7424979 Fragrance vibrating and nebulizing module

An improved fragrance vibrating and nebulizing module comprises a holding unit which is installed on an opening of a container, so that a plurality of retainers can retain a wick in place. Two engaging portions formed on an outer periphery of the holding unit can cooperate with guide grooves formed on a central annular portion of a vibrating and nebulizing base and be rotationally connected to be in place. After a receiving space of a top retaining unit is mounted with a resilient element and a vibrating plate, the resilient element and the vibrating plate are retained in place by a resilient retainer. Through holes of the top retaining unit are connected with resilient tenons on the vibrating and nebulizing base. While in use, the vibrating and nebulizing module can draw up a fragrance via the wick, so that the fragrance is nebulized and dispersed in contact with outside air.
