ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a bubble generating device having a float and a weight to maintain the device in a desired position in the water.
BACKGROUND OF THE INVENTION
A conventional bubble generating device is shown in FIG.
1
and generally includes a two blade means
101
driven by a motor
100
. The bubble generating device is floated on water such as a pond, and the blade means
101
rotated to splash water in the air so that the water become many tiny water drops and fall into the water so as to increase the oxygen in the water. However, the bubble generating device cannot bear strong wind and the blades of the blade means
101
can only affect the water on the top surface of the water.
FIG. 2
shows another bubble generating device which has two blades
102
on a shaft
103
and the device can be sunk in water. The blades
102
stir the water in the casing
104
of the device to generate bubbles. This is a bulk device and requires a motor to drive the shaft and a gear reduction device to adjust the speed of the shaft. This is costly and the device cannot operate in deep water.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a bubble generating device and includes a shaft connected to a first float and a plurality of frames are connected to the shaft at there respective first ends. A porous device has a plurality of lugs extending therefrom and is connected to mediate portions of the frames by bolts. A fitting extends from the porous device and is connected to a pipe.
The primary object of the present invention is to provide a bubble generating device that can be operated in desired depth of water and the has a simple structure.
These and further objects, features and advantages of the present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, several embodiments in accordance with the present invention.
