  • Patent number: 6349492
    Abstract: A liquid ornament having means for creating continuous liquid flow is provided. The liquid ornament includes a display chamber for containing liquids, such as water and oil, and a control chamber for accommodating the means for creating liquid flow. The means for creating liquid flow mainly include an elastically flexible material that forms a partition between the display chamber and the control chamber, a push member having a free end contacting with the flexible material, a magnet attached to the free end of the push member, and a coil mounted within a magnetic field of the magnet. When the coil is continuously supplied with an electric current, it alternately magnetically repulses or attracts the magnet and accordingly causes the free end of the push member to intermittently push or strike the flexible material, producing continuous liquid flow in the display chamber when the whole liquid ornament is in a still state.

  • Patent number: 6270420
    Abstract: An ornamental liquid container for creating dynamic views is provided. The container mainly includes a hollow housing divided into top, middle and bottom chambers and a base connected to and separated from the bottom chamber by an elastic and soft diaphragm. The top and the bottom chambers communicate with each other via a hollow tube extended through the middle chamber, so that colored water can be stored in the bottom chamber and move into the top chamber via the hollow tube and clear oil can be stored in the middle chamber and the hollow tube above the colored water. A cam is mounted in the base and rotated by a driving unit to intermittently pat the diaphragm above it, causing the diaphragm to locally project into the bottom chamber and compress the colored water therein to move into the top chamber via the hollow tube and then drips down into the middle chamber to move along a water dispensing member and produce dynamic views in the hollow housing.

  • Patent number: 5329714
    Abstract: A floating body disposed within a liquid-filled container has top and bottom portions provided with extensible and retractable objects, some of which have a greater buoyancy then the body and the remainder of which tend to sink in the liquid. The body and objects have various configurations and designs which create three-dimensional changes during floating of the body each time the container is turned upside-down.
