Abstract:
1. A crystal ball structure that delivers a virtual snowfall scene and light effect, comprising a seat and a crystal ball on the seat, a thematic model and a liquid in the crystal ball; a rubber plug and a bottom opening of the crystal ball blocked with the rubber plug to avoid leakage, and a fixing plate and a fixed cylinder and the rubber plug is fixed in the fixed cylinder extending from the fixing plate; characterized in that: said fixing plate has a neck extending upwards at the center, which has a model container inside and an agitating mechanism outside, wherein the model container is designed to fix said thematic model with a surface, a long tube extending downwards, and a short tube extending upwards; the long tube runs through the neck of said fixing plate and is equipped with a seal ring to avoid leakage; the short tube is connected to a transparent tube on the top, which contains a luminous element as a light source; a gear rack and an agitating mechanism located between the fixing plate and the model container; the agitating mechanism comprising a plate and fans on the circumference of the plate; and a shaft hole at the center of the plate, and the plate is fixed over the neck of the fixing plate through the hole; and with the gear rack outside of the hole; a driving part, a gear train and a first gear of the gear train having a shaft and coupled with the gear rack that is at the outside shaft hole of said agitating mechanism; a second gear and the shaft of the first gear passes through the through-hole of the fixing plate and is equipped with a seal ring, and it is coupled with the second gear of the gear train on the other end; the second gear is coupled with the gear of the driving part; the center hole of the driving part is fixed on the bottom end of the long tube extending downwards along said model container, and it has a gear coupled with the second gear and a driving arm extending downwards; a spring and the luminous element delivers decorated light of the thematic model by said instrument; when the driving arm of the driving part rotates under the drive of the spring, the driving part and the model container drives the thematic model to rotate, and at the same time, the gear of the driving part transfers the motion to the second gear, the first gear, and the gear rack around the shaft hole of the agitating mechanism, which in turn rotates and stirs the liquid with its fans.
