Description
Technical Field
The utility model relates to a filter field, concretely relates to oil cleaner.
Background
Engine oil filterFor removing oil, also known as oil gridsDustMetal particles, carbon precipitates and soot particles, and protecting themEngineIn the conventional oil filter, the end surface of the outer side of the filter element is generally corrugated to increase the filtering area of the filter paper, so that the filter paper is troublesome to operate when being connected with a central pipe.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that not enough to above-mentioned prior art provides an oil cleaner, when guaranteeing filter paper filter area, reduces the operation degree of difficulty of connecting filter paper and center tube.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides an oil filter, includes the casing, with the casing cooperation cavity that is equipped with in upper cover, the casing of being connected, be equipped with the filter core in the cavity, the upper cover is equipped with oil inlet and oil-out, characterized by: the filter element comprises a central tube and filter paper arranged on the central tube, the diameters of two ends of the central tube are the same, the diameter of the middle section of the central tube is smaller than the diameters of the two ends to form a curved surface, and the filter paper is paved on the curved surface.
The utility model discloses further setting is: the diameter of the middle section of the central tube is one half of the diameter of the two ends of the central tube.
The utility model discloses further setting is: the both ends of center tube are equipped with the end cover, the end cover can be dismantled with the center tube and be connected.
The utility model has the characteristics as above: because the center tube is thick in both ends and thin in the middle, the area of the filter paper covered on the center tube is large, the filtering area is ensured, the corrugated shape is avoided, and the connection operation is simpler and more convenient.
The present invention will be described in further detail with reference to the accompanying drawings and examples.
