Abstract:
1. A decorative device enabling ornaments to rotate and move up and down inside a crystal ball amidst fluttering, shiny disc snowflakes, comprising: a motor mechanism, comprising: a motor; a gear set supporting frame positioned above the motor; a gear set gland that covers the gear set supporting frame; a plurality of transmission gears positioned between the gear set supporting frame and the gear set gland; and which mutually mesh; a plurality of gear shafts respectively extending into centers of the transmission gears; a lower magnet gland positioned above the gear set gland that enables the gear shafts to penetrate therethrough; a lower double-sided magnet positioned above the lower magnet gland that enables the gear shafts to penetrate therethrough; a transmission magnet gland positioned above the lower double-sided magnet that enables the gear shafts to penetrate therethrough; a gear mechanism, comprising: a carrier frame, an upper surface of which is provided with a recess, two air rubber plug holes and a watertight ring support; a carrier frame gland that covers the recess of the carrier frame, a plurality of bolt holes are defined in the carrier frame gland; a magnet impeller shaft positioned center of the recess of the carrier frame; two air rubber plugs that are respectively fixedly plugged into the air rubber plug holes; an upper magnet gland positioned in the carrier frame gland that enables the magnet impeller shaft to penetrate therethrough; an upper double-sided magnet positioned above the upper magnet gland that enables the magnet impeller shaft to penetrate therethrough; a magnet impeller positioned above the upper double-sided magnet that enables the magnet impeller shaft to penetrate therethrough; a watertight gasket positioned within the watertight ring support of the carrier frame; a main transmission shaft that penetrates the watertight gasket and extends into the watertight ring support of the carrier frame, an upper portion of the main transmission shaft is provided with an embedding piece; a rotary mechanism, comprising: a transmission shaft, a bottom end of which enables the embedding piece of the main transmission shaft to fixedly embed therein; a fixing post sleeve fixedly disposed on the transmission shaft, screws penetrate through holes of a bottom disk of the fixing post sleeve to enable fixedly bolting into the bolt holes of the carrier frame gland; a rotary tray, center of which is provided with a circular recess, and a plurality of post holes are defined lateral to the circular recess; two large umbrella-shaped gears that are respectively disposed within the circular recess of the rotary tray; a plurality of eccentric wheels, an outer side of each of which is provided with a protruding pin, small umbrella-shaped gears respectively located at ends of the eccentric wheels extend into the circular recess of the rotary tray and respectively mesh with the large umbrella-shaped gears; a gear gland that covers the circular recess of the rotary tray and is fixedly bolted using a screw; a screw that penetrates a filling piece and is fixedly bolted into a top end of the transmission shaft; a plurality of ornament hanger rods that respectively penetrate the post holes of the rotary tray and are fixedly bolted with screws, a toy figurine or ornament suspends from a lower end of each of the ornament hanger rods; a plurality of sliding pieces that enable the protruding pins of the eccentric wheels to abut against the sliding pieces, sliding piece shafts respectively penetrate shaft holes defined in the sliding pieces and fixedly embed into cylindrical posts of the rotary tray; a crystal ball that is disposed on and seals the carrier frame, the crystal ball is filled with water and shiny disc snowflakes, and when the motor drives and rotates the transmission gears, then mutually repelling of the upper and lower double-sided magnets drive and rotate the magnet impeller wheel, thereby causing whirling of the water and fluttering of the shiny disc snowflakes, moreover, the transmission shaft is caused to rotate, thereby rotating the rotary tray and the toy figurines or ornaments installed thereto, and the large and small umbrella-shaped gears drive and rotate the eccentric wheels, thereby driving and causing up and down movements of the toy figurines or ornaments suspended from the lower ends of the ornament hanger rods.
