ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a liquid ornament, and more particularly to a liquid ornament having a movable ornament therein.
2. Description of the Related Art
The liquid ornament, also named “water ball”, is a very traditional ornament and usually has at least one ornament object inside a sealed liquid vessel. Most of “water balls” do not provide the power to move the ornament objects. Few of “water balls” use mechanical energy providing device, such as a clock motor, a motor with music generation (musical movement, used a lots in Music Boxes), etc, to move ornament objects so that more amusing or entertaining effect can be generated. For example, U.S. Pat. No. 5,272,681, “Dynamic Fluid Clock”, uses a clock motor to move its ornament object.
Please refer to
FIG. 10
regarding the schematic view of U.S. Pat. No. 5,272,681. An ornament object
95
is connected with a magnet
93
by a string
94
. There is another magnet
92
mounted on the second hand
91
of a clock motor. The magnet
93
is adhered to the magnet
92
due to the magnetic force so that when the second hand
91
moves, the magnet
92
and the magnet
93
will also move simultaneously. Therefore the ornament object
95
will also move accordingly in a manner of a circle movement.
However, it is not entertaining enough because the ornament object
95
move so regularly and also in a manner of two-dimensional movement only.
SUMMARY OF THE INVENTION
The main object of the present invention is to make the ornament in a liquid ornament achieve the effect of three-dimensional movement.
To achieve the object, the liquid ornament of the present invention includes a casing, a bottom casing, a base, at least one ornament, at least one liquid, and a mechanical energy providing device to provide mechanical energy for the ornament to move.
One of the subject matter of the present invention is that the liquid ornament further comprises two magnetic objects positioned under the bottom casing wherein the mechanical energy providing device can move these two magnetic objects. In addition, there are two passive magnetic objects positioned above the bottom casing and are adhered to two magnetic objects respectively due to the magnetic force. Therefore, once two magnetic objects move, and then two passive magnetic objects will move accordingly.
Another subject matter of the present invention is that the liquid ornament further comprises at least one string connected with the ornament and two passive magnetic objects so that the ornament moves accordingly. Therefore, the ornament can move in three-dimensional manner by changing the relative positions between two magnetic objects.
