ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a lamp showing movable floating ornaments. The lamp has a closed clear container, in an upper part of which liquid and floating ornaments are contained and in a lower part of which a liquid-guiding means and a propeller are mounted. A driving means is mounted below the container to rotate the propeller. When the propeller is driven to rotate, liquid flowing from the upper part into the lower part of the container via the liquid-guiding means is forced back into the upper part of the container at an increased speed, so that the floating ornaments in the upper part of the container are caused to move around and create dynamic scenes in the container. Such movable floating ornaments are beautifully shown when the lamp is switched on.
U.S. Pat. No. 5,426,877 entitled “Dynamic Liquid Display Structure” and granted to the inventor of the present invention on Jan. 4, 1994 discloses an ornament
10
generally shown in
FIGS. 1 and 2
. The ornament
10
looks like a lamp and mainly includes a clear and closed container
11
, driving means
12
and lighting means
13
. The driving means
13
is, for example, an electromagnetic driving mechanism for rotating a propeller
111
inside the closed container
11
, so that the propeller
111
drives clear liquid in the closed container
11
to rush upward and thereby carries a plurality of balls
112
in the closed container
11
to move upward along an upright hollow tube
113
. When the balls
112
reach a top opening of the tube
113
, they are carried by the liquid to move out of the tube
113
and slowly and freely fall in the liquid. Light emitted by the lighting means
13
illuminates the container
11
and the balls
112
moving upward and downward in the container
11
, enabling the ornament
10
to be a good lamp having ornamental effect.
It is tried by the inventor to make further improvements on the disclosure of U.S. Pat. No. 5,426,877, so that a superior lamp showing movable floating ornaments is provided.
SUMMARY OF THE INVENTION
A primary object of the present invention is, therefore, to provide a lamp showing movable floating ornaments. The lamp includes a lighting means for emitting light, and a closed clear container for containing and showing liquid and floating ornaments therein. A liquid-guiding means and a propeller are provided in a lower part of the container, and a driving means is provided below the container for turning the propeller. When the propeller is driven to turn, liquid flowing into the lower part of the container via the liquid-guiding means is continuously forced back into an upper part of the container via the liquid-guiding means at increased speed, so that floating ornaments in the liquid in the container are brought to move around and create dynamic scenes in the container.
