Abstract
This invention relates to a crystal ball structure that delivers virtual snowfall scene and light effect, comprising of a crystal ball enclosing a thematic sight and liquid, a seat to support the crystal ball and contain a drive mechanism, an agitating mechanism that can rotate to stir the liquid, and a light to enhance the decoration effect. Under the drive of the dynamic drive mechanism, a gear train and an agitating mechanism, which is powered from a manually fastened spring, the fans of the agitating mechanism agitates the liquid to stir the floating matter dispersed in the liquid and generate a virtual scene of snowfall scene under the reflection of the light.
