Description
TITLE: DISPOSABLE OIL FILTERING DEVICE
(a) Technical Field of the Invention
The present invention generally relates to oil filtering devices for automobile engines, and more particularly to an oil filtering device having replaceable and disposable filter.
(b) Description of the Prior Art
A conventional oil filtering device 110, as shown in FIGS. 1 and 2, for automobile engines mainly contains a filter 3 housed inside a filter housing 2 which is sealed by a cover 1.
To assemble the oil filtering device, an elastic element 6 is placed inside the filter housing 2 and the filter 3, sandwiched between a top cap 31 and a bottom cap 32, is then placed inside the filter housing 2 on the elastic element 6. The elastic element 6 is fixedly attached the bottom cap 32 and, when the oil to be filtered enters the filter housing 2, the elastic element 6 is able to support the filter 3 into a piston-like movement. Finally, the cover 1 is welded to the filter housing 2 to complete the assembly. Please note that a disc-shaped washer 4 having a central tightening ring 41 is positioned between the filter 3 and the cover 1. The tightening ring 41 tightly couples the cover 1 and the top cap 31 of the filter 3, so as to prevent unfiltered oil from permeating into the filter 3 through an outlet 12 and mixing with the filtered oil.
The oil filtering device 110 operates as follows. Unfiltered oil flows through the inlet 11 and, when the unfiltered oil has exceeded the bearing capacity of the washer 4, the unfiltered oil overflows from the rim of the washer 4 and enters the oil filtering device 110. The filter 3 contains vanes centrifugally fanning loosely out and, for each vane, there is a small hole 30.
The unfiltered oil flows through the vanes and the holes 30 of the filter 3 and is thereby filtered. The filtered oil then flows out of the center of the filter 3 and the outlet 12 into a carburetor. The conventional filter 3 provides limited filtration as the oil flows centripetally through the filter 3 and, due to its loosed and closed structure, the entire filtering device 110 has to be replaced frequently, increasing the maintenance cost of the automobile owner.
SUMMARY OF ThE INVENTION
Therefore, a novel oil filtering device is provided herein to obviate the shortcomings of the conventional oil filtering device.
The prevent invention contains a cover, a filter housing, and a disposable filter housed inside the filter housing. The filter has an enlarged top end so that the filter is tightly joined with the filter housing. Threads and grooves are provided on the cover and the filter housing, respectively, so that the cover could be tightly joined with the filter housing. The cover has an outlet hole connected to the carburetor and a downward extended outlet tube threading into an axial channel of the filter.
Compared to the prior art, the present invention conducts oil filtration in a top-down manner. Together with the filter having a tighter structure (compared to the centrifugal vanes of the prior art), the present invention provides a superior filtration effect and, therefore, both the oil and the filter could be used for an extended period of time. Further more, only the filter needs to be replaced while the cover and the filter housing could be continuously reused, significantly reducing the cost of maintenance.
The foregoing objectives and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.
Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
FIGS. 3 and 4 show an oil filtering device according to an embodiment of the present invention. As illustrated, the oil filtering device 100 contains a cover 1, a filter housing 2, and a filterS. To assemble the oil filtering device 100, the filter S is placed inside the filter housing 2 through a top opening of the filter housing 2, and then the filter S is sealed inside the filter housing 2 by screwing the cover 1 onto the top opening. The filter 5 is made of a water-absorbing material, such as paper, so that the water in the oil could be quickly absorbed. The filter 5 has an enlarged top end 53 so as to enhance its integration tightness with the filter housing 2. The cover 1 has an outlet tube 13 extended downward from an outlet hole 12 in the center of the cover 1 into an axial channel of the filterS. Matching threads and grooves are provided around the circumferences of the cover 1 and the top opening of the filter housing 2 for the tight joining of the cover 1 to the filter housing 2. After assembly, the oil filtering device 100 could then be connected to a carburetor through the outlet hole 12.
FIG 5 is a perspective diagram showing the oil filtering device 100 after it is assembled. As illustrated, the filter 5 is encased inside the filter housing 2 and the cover 1 is joined to the top opening of the filter housing 2 to seal the filter 5.
As sho in FIG 6, in addition to the outlet tube 13, a number of inlet holes 11 are provided on the cover 1 to allow unfiltered oil to permeate into the filter housing 2 and then to be filtered by the filter 5. The tight attachment between the enlarged top end 53 of the filterS and the filter housing 2, and the outlet tube 13's extension into the filter S effectively help preventing unfiltered oil from entering the outlet hole 12.
As further shown in FIG 7, the purpose of having the enlarged top end 53 is so that the filterS is able to tightly join to the filter housing 2.
FIG 8 is a sectional diagram showing how the oil filtering device 100 operates. As illustrated, the unfiltered oil from top to bottom enters the filter housing 2 via the inlet holes 11. As the unfiltered oil descends due to gravity, it is thoroughly filtered by the filter 5. The filtered oil then enters the outlet tube 13 from the bottom and out of the outlet hole 12. The filter S's tight structure allows repeated usage. The enlarged top end 53's tight coupling with the filter housing 2 also enhances the filtration effect. Due to its superior filtration effect, the filter 5 could be used for a much longer period of time. In addition, after a period of usage, only the filter 5 needs to be disposed and replaced while the cover 1 and the filter housing 2 could be reused, thereby significantly reducing the maintenance cost.
To further illustrate the improvement and practical value of the present invention, a comparison of the present invention with the conventional oil filtering device is as follows.
For the conventional oil filtering device, its filter is usually contains centrifugal vanes and the filtration is engaged when the oil flows from the sides into the center of the filter. Such kind of filtration has an inferior performance. As such, the oil and filter (and therefore the entire oil filtering device) have to be replaced more frequently, increasing the burden to consumers.
In contrast, the oil filtering device of the present invention conducts oil filtration in a top-down manner. Together with the filter having a tighter structure (compared to the centrifugal vanes of the prior art) and the tight coupling between the enlarged top end of the filter and the filter housing, the present invention provides a superior filtration effect and, therefore, both the oil and the filter could be used for an extended period of time. Further more, only the filter needs to be replaced while the cover and the filter housing could be continuously reused, significantly reducing the cost of maintenance.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
