Abstract
A bubble generating device includes a shaft connected to a float and a plurality of frames connected to the bolt at their first ends. A porous device is connected to the respective mediate portions of the frames. A bolt extends through respective second ends of the frames and a weight is connected to the bolt. A pipe is connected to a fitting extending from the porous device so as to provide air into the porous device to generate bubbles. The bubble generating device can be maintained in water by adjusting the float and the weight.
Description




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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring to

FIGS. 3

to


5


, the bubble generating device of the present invention comprises a shaft


1


connected to a first float


20


and a threaded section


12


is defined in a lower end of the shaft


1


. A plurality of frames


30


each have a first hole


31


defined in a first end thereof and a second hole


32


defined in a mediate portion of each frame


30


. The threaded section


12


extends through the float


20


and the three first holes


31


and engaged with a nut. A hole


11


is defined in a top of the shaft


1


so that a cable


13


tied with the hole


11


to hang the device.




A porous device


40


for generating bubbles is enclosed by the frames


30


and a pressing ring


50


located on a top surface of the porous device


40


. A plurality of lugs


51


extend from the pressing ring


50


and each lug


51


has a hole


510


. A plurality of first bolts extend through the respective second holes


32


in the frames


30


and the holes


510


in the lugs


51


to connect the porous device


40


to the frames


30


. A third hole


33


is defined through a second end of each frame


30


and a second bolt


34


extends through the third holes


33


of the frames


30


and is engaged with a first weight.


35


. A fitting


42


extends from the porous device


40


and is connected to a pipe


41


so that when air is introduced in the porous device


40


via the pipe


41


from a source of air, bubbles are generated by the porous device


40


.




As shown in

FIG. 6

, a second float


500


is connected to the cable extending from the shaft


1


and a second weight


54


is hung on the second float


500


by a cable


540


. The pipe


41


is attached to the cable


540


so as to reduce the possibility of affection of the bubble generating device by the un-positioned pipe


41


.





FIG. 7

shows a weight board


52


is located below the porous device


40


and posts


53


extend from the board


52


. The second float


500


is connected to the posts


53


so that the porous device


40


is located between the board


52


and the second float


500


. The second bolt


34


extends through the board


52


and the first weight


35


is hung below the board


52


. This structure allows the bubble generating device to be operated in a deep and wavy water. The lugs


51


can also be made integrally with the porous device


40


.




The device can be lowered into water because the weight


35


/


52


and the float


20


/


51


provides an upward force so that the device can be stayed at a desired depth in the water. The float


20


/


51


ensures the top surface of the porous device


40


always to face upward. By this way, the device can be operated in water and will not be affected by strong wind because only the cable is exposed out of the water.




While we have shown and described various embodiments in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope and spirit of the present invention.
