ABSTRACT:
BACKGROUND OF THE INVENTION
The rapid development of the commercial and industrial field stimulates people to constantly upgrade their living quality. People's attitude toward an article to be purchased is much more strict than ever before. The article must be reasonably economical in price and absolutely novel and fashionable in structure and function to win a buyer's trust. For an ornamental liquid container that has become a popular interior decoration and must have limited dimensions for holding oil and water therein, it is really uneasy to make such ornamental liquid container distinct in appearance, structurally watertight, and capable of displaying unique and dynamic views in a small space.
SUMMARY OF THE INVENTION
A primary object of the present invention is to provide an ornamental liquid container that employs simple eccentric motion of a cam to intermittently push an elastic and soft diaphragm toward and therefore compress a water chamber of the container, causing water in the chamber to circulate in the container along a predetermined path and create dynamic views.
Another object of the present invention is to provide an ornamental liquid container that employs simple structure to create dynamic views and is therefore economical and practical for use.
A further object of the present invention is to provide an ornamental liquid container, a basic structure of which for creating dynamic views can be associated with differently shaped housing and internal water dispensing member, so that the views displayed in the liquid container is not only dynamic but also changeful.
To achieve the above and other objects, the ornamental liquid container of the present invention 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 means 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.
