ABSTRACT:
A water spraying device for a crystal ball containing a decorative item, essentially comprising a pump housing having a water inlet and outlet and fixed at both sides to a rubber plug seat which is mounted below the base for the decorative items within the crystal ball. The device also includes a pump impeller driven by a small type of motor within said pump housing to pump the water entering from the inlet to the outlet for spraying out, thus making the snow within the crystal ball to fluff and tumble and to form a very attractive sight. The pump impeller and pump housing are configured such that it does not require the motor to be mounted before filing the crystal ball with clean water.
