Description

TITLE: A WIND-DRIVEN VENTILATING FAN This invention relates to a wind-driven ventilating fan.
The conventional ventilating fan sold on the market is driven by electricity thereby wasting energy. Hence, various wind-driven ventilating fan has been developed to eliminate this drawback. However, none of the wind-driven ventilating fans is satisfactory in use and the structure thereof is too complicated.
Therefore, it is an object of the present invention to provide a wind-driven exhaust fan which can obviate and mitigate the above-mentioned drawbacks.
This invention relates to a wind-driven ventilating fan.
It is the primary object of the present invention to provide a ventilating fan which is driven by wind.
It is another object of the present invention to provide a wind-driven ventilating fan which is of high efficiency.
It is still another object of the present invention to provide a wind-driven ventilating fan which can prevent water from entering into a house.
It is still another object of the present invention to provide a wind-driven ventilating fan which is simple in construction.
It is a further object of the present invention to provide a wind-driven ventilating fan which is low in cost.
T'r.e present Inentio provides a wind driven -entllatlna fan as set out n Cai:n 1 or 2.
Other objects and merits and a fuller understanding of the present invention will be obtained by those having ordinary skill in the art when the following detailed description of the preferred embodiment is read in conjunction with the accompanying drawings wherein like numerals refer to like or similar parts.
FIG. 1 is an exploded view of the present invention; FIG. 1A shows another preferred impeller; FIG. 2 shows the working principle of the present invention; and FIG. 3 is a cutaway view of the present invention.
For purpose to promoting an understanding of the principles of the invention, reference will now be made to the embodiment illustrated in the drawings. Specific language will be used to describe same. It will, nevertheless, be understood that no limitation of the scope of the invention is thereby intended, such alternations and further modifications in the illustrated device, and such further applications of the principles of the invention as illustrated herein being contemplated as would normally occur to one skilled in the art to which the invention relates.
With reference to the drawings and in particular to FIGS. 1 and 3 thereof, the wind-driven ventilating fan according to the present invention mainly comprises a fixed annular member 10, a free annular member 20, a plurality of curved vanes 50, an outer cover 80, an inner cover 81, a support 30, a mounting 40, and an impeller 70.
As illustrated, the free annular member 20 is rotatably fitted on an outer side of the fixed annular member 10. The connection between the free annular member 20 and the fixed annular member 10 is well known to those having ordinary skill in the art and is not considered a part of the invention.
The curved vanes 50 are connected with the free annular member 20 at one end and the outer cover 80 at another end. The inner cover 81 is mounted on the bottom of the outer cover 80 (see FIG. 3).
The support 30 is fixedly mounted on the fixed annular member and provided with an axle 60 downwardly extending from a center thereof (see FIG. 1) to engage the inner cover 81.
The mounting 40 is fixedly installed on the free annular member 20 and has a central hole 41 for the passage of the axle 60.
The impeller 70 is fixedly installed on the mounting 40 and sleeved on the axle 60.
When hot air is conveyed from the lower position to the higher position, the impeller 70 will be driven thereby rotating the mounting 40, the free annular member 20 and the curved vanes 50 and therefore providing ventilating effect. FIG. 2 shows the working principle of the present invention.
The invention is naturally not limited in any sense to the particular features specified in the forgoing or to the details of the particular embodiment which has been chosen in order to illustrate the invention.
Consideration can be given to all kinds of variants of the particular embodiment which has been described by way of example and of its constituent elements without thereby departing from the scope of the invention. This invention accordingly includes all the means constituting technical equivalents of the means described as well as their combinations.
