ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an improvement of water ball, and more particularly, to a water ball with water screen design, wherein an ornamental object in the water ball can be prevented from being wetted, with effect of easy assembly and with long using life.
2. Description of the Prior Art
FIG. 1
is a schematic drawing of the structure of a conventional water ball which has a transparent glass hood
12
disposed at the top of a base
11
and filled with liquid
13
so that the ornamental object
14
at the top of the base
11
is presented in the liquid
13
and creates a dim beauty. However, the using life of the prior art ornamental object
14
is easily decreased after soaked in the liquid
13
for a long period. In order to increase the entertainment effect of the ornamental object
14
and to make the water ball more beautiful, the water ball is normally provided with light
15
on the ornamental object
14
or at the side thereof. However, the light
15
is situated in the water so that the water resistance has to be perfectly ensured; otherwise, a short circuit can lead to cause malfunctions by being wetted. Accordingly, the manufacturing of the prior art water ball
1
is time-wasted and inconvenient. Besides, the ornamental object
14
and the light
15
are soaked in the water for a long period, and it will be easily wetted and oxidized to reduce the using life, even to lead to frequent defects.
SUMMARY OF THE INVENTION
It is a primary object of the present invention to provide a water screen type water ball, wherein a water pipe is fitted at the center of the inner rim of the circular arc-shaped transparent hood, and a water post is raised through the water pipe by means of a pump at the base, and a small clearance has to be reserved between the inner rim of the transparent glass hood and the outlet end of the water pipe so that the water post can flow down along the inner rim of the transparent hood after outflow through the outlet; accordingly, the shape of a transparent water ball is presented.
It is a further object of the present invention to provide a water screen type water ball which can protect the ornamental object and the light inside of the glass hood from being wetted in order to prolong the using life thereof.
