Description

Automotive oil filter {The oil filter for automobil}

This paper relates to an automobile oil filter that can filter engine oil of a vehicle. In particular, the oil filtration portion of the oil filter is improved to maximize the filtration area for filtering oil in a limited space, thereby improving filtration efficiency. Of course, the present invention relates to an oil filter for automobiles that can further prevent the pollution of the environment by further increasing the life of the oil filter.

In general, the oil filter for automobiles allows the engine to run smoothly by reflowing only the refining oil through which the waste oil introduced from outside in the limited space has passed through the element to smoothly operate the engine of the automobile. It is well-known that it has been possible to extend the lifespan.

However, the conventional engine oil filter 101 has a hollow portion 104 formed inside the housing 102, as shown in FIGS. Inserting the filter body 103 attached to the iron plate having a thickness of about 0.4 mm, and the pressing spring piece 106 is mounted on the inner surface of the upper side of the filter body 103 and a plurality of waste oil inlet holes 108 ) And the cover 107 is formed by fixing a discharge hole 109 through which the filtered oil can be introduced into the engine at the center thereof. The oil filter 101 is a waste oil inside the engine. As shown in the direction of the arrow in Figure 5 when the inlet hole 108 perforated in the periphery of the cover 107 flows between the pressing spring piece 106 of the lower cover 107 to filter the impurities of the waste oil in the filter paper 105 After the oil filtered through the hollow 104 is collected and discharged in the direction of the arrow ( 109) flowed into the engine.

However, the filter paper 105 of the filter main body 103 for filtering waste oil in the oil filter 101 as described above is cut to a certain size by continually working in an M shape in a bending machine, and then bonded to a cutting surface. Since the end face is bonded to a 0.4 mm thick steel plate, the oil is filtered from the outside to the inside, so when the waste oil discharged from the engine flows in, the oil enters the outside of the filter main body 103 by the pressure of the filter paper 105. The filter paper 105 of the oil filter 101, which is filtered through the clean and filtered oil only to be introduced into the engine, is used to maintain an extremely limited filtration area in a limited space, which not only decreases the filtration efficiency but also has a long service life. Because of this short and frequent replacement, there was a problem that excessive consumption of resources and maintenance costs as well as environmental pollution.

On the other hand, in order to increase the filtration efficiency, the size of the housing can be enlarged by increasing the capacity of the housing, but such an oil filter is very difficult to implement because the structure of the engine room of the car is extremely limited. When the size of the filter is enlarged, there is a problem that the manufacturing cost increases.

The present invention has been devised to solve the above-described problems of the related art. For this purpose, the paper also rolls or stacks the filter paper structure of an element installed inside the housing to maximize the filtration area within a limited space. After improving the upper and lower surface into zigzag pocket type, sufficient filter area to filter the oil is secured, and the upper and lower surfaces of the filter main body are kept open so that the waste oil flowing from the engine immediately reaches the minimum pressure. It is to provide a car oil filter that will allow to further increase the filtration efficiency by allowing the filter to be filtered cleanly as well as to prolong the life of the oil filter.

The oil filter of the present invention capable of achieving the above object has a housing having an upper side and an arc having a lower side, and a filter paper outside the cylindrical inner tube so as to be inserted into the housing to filter waste oil. The filter main body is formed in the form of overlapping pockets to be retained, and the upper and lower surfaces are zigzag-bonded and fixed to each other. Covering the periphery of the perforated hole in which waste oil can be introduced into the periphery and the center is characterized by consisting of a cover perforated discharge hole for the discharge of the filtered oil to the engine.

Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.

2 is a cross-sectional view taken along the line AA of FIG.

3 is a cross-sectional view taken along the line BB of FIG.

The oil filter 1 of the present invention has a cylindrical inner as the upper side of the leaf spring 6 in a state where the leaf spring 6 is placed on the lower surface of the housing 2 with the upper side open as shown in FIGS. The filter paper 5 is formed on the outside of the tube 4 so that the filter paper 5 is stacked in a stack so as to maintain a constant gap, and the filter body 3 is fixed to the upper and lower surfaces by zigzag.

At this time, the lamination of the filter paper 5 may be adopted by a filtration method of winding the upper and lower sides by winding in rolls with the inner tube 4 as an axis, and overlapping with the inner tube 4 as the axis. It is also possible to adopt a filtration method of laminating in the manner and fixing the upper and lower surfaces by adhesion.

In addition, a plurality of inlet holes 8 through which the waste oil is introduced into the periphery of the filter body 3, that is, the upper side of the housing 2, are drilled, and in the center, the filtered oil can be discharged into the engine. The cover 7 is formed by covering one discharge hole 9 with a perforated lid 7.

The oil filter 1 of the present invention configured as described above is installed in an engine oil circulation passage of a vehicle to filter engine oil. As shown in FIG. 4, the waste oil passing through the engine covers the upper part of the housing 2. When introduced into the perforated hole (8) perforated in the periphery of the) and introduced into the filter body (3) side, the introduced waste oil flows between the valleys between the filter paper (5) and passes through the filter paper (5) at the inlet pressure of oil After the impurities contained in the waste oil are removed from the filtrate, the filtered oil passes through the leaf springs 6, which are installed on the lower surface, and is perforated in the center of the hollow of the inner tube 4 and the cover 7. Through the discharge hole (9) to be continuously introduced into the engine in the direction of the arrow is to maintain the filtration function.

On the other hand, after the used engine oil is introduced into the oil tank, it is supplied to the primary oil filter by the pressure of the oil pump, and the filtered oil is introduced into the pocket filter paper 5 in the process of dispersing the filtered oil to each driving part of the engine. The filtering function is improved by filtering in a state in which the pressure dispersion area is dispersed in the widest possible area in a predetermined space.

As described above, the oil filter of the present invention has a pocket of the filter body inserted into the housing, which overlaps the inner tube, and overlaps the upper and lower surfaces in a zig-zag structure, thereby forming a large area of impurities contained in the engine oil. As a result of the collection filtration, the filtration area becomes wider in the limited housing space, thereby further improving the function of the filter and prolonging the life of the filter.

In the case of the filter currently in use, since the filter area is manufactured by M-shaped continuous bending work, the oil filter should be replaced at a running distance of 3,000 km to 9,000 km. It is a very useful design that can improve the convenience of users as well as saving resources by increasing the exchange period by extending the use distance by increasing the use distance to 18,000km ~ 25,000km, which is about three times.
