Description

an oil filter

Technical field:

The utility model relates to an engine oil filter, in particular to an engine oil filter capable of filtering impurities such as iron powder.

Background technique:

At present, the common oil filter structure is that several oil inlet holes are arranged on the outer side of the cover end surface below the oil filter body, and a flow port with a fixed thread is provided in the center as the oil outlet, and then There is a bent filter paper core on the inner side of the cylinder wall, and a metal mesh is arranged around the center of the body. Its main feature is that a ring is connected to the lower outlet of the metal mesh, and the ring forms a stepped The bending body is used to clamp the strong magnetic oil filter rod, which can absorb the iron powder in the oil and filter out cleaner oil.

Looking at the above conventional oil filters in detail, it is not difficult to find that there are still some deficiencies in them. The main reasons are summarized as follows:

In this structure, a strong magnetic filter rod is additionally arranged in the center of the body, and the filter rod is vertically arranged on the passage that the oil outlet must pass through, so as to absorb the iron powder in the engine oil. However, the structure of this kind An additional filter rod is required for manufacturing, and the manufacture and assembly of the filter rod is very troublesome, which relatively increases the manufacturing cost, and the residual impurities in the engine oil are adsorbed on the filter rod. If the magnetic force of the filter rod fades after a period of use, The iron powder that was originally adsorbed on the filter core rod falls and flows out from the oil outlet together, and the filtering effect is not good.

Furthermore, the oil outlet of this structure is formed into a protruding shape, so that the oil flowing in from the filter paper core at the bottom needs to flow to the top of the filter core rod before the oil can flow out from the outlet, which is very inconvenient in flow. Smooth, it is very likely to cause turbulence, which is not ideal in use.

Invention content:

The purpose of the utility model is to provide an engine oil filter, which is simple and easy to manufacture, can filter out impurities, and has smooth oil filtration and strong practicability.

In order to achieve the above object, the utility model adopts the following technical solutions:

An engine oil filter, in which a filter element is arranged in the engine oil filter body, wherein, the cover of the body is provided with an inlet hole and an outlet hole for oil to flow in and out, and a filter element is provided with a The outlet hole is connected to the flow port. The inner circumference of the filter core is provided with a filter screen, and a bent filter paper is arranged along the periphery of the filter screen. At least one set of magnetic units is attached to the crease of the filter paper. The units are annularly distributed at the creases around the filter paper to absorb and filter impurities in the oil.

There is a slightly protruding annular platform on the inner side of the flow port that communicates with the outlet hole of the body on the filter core.

According to the above structure, the utility model has the following beneficial effects relative to the known structure:

1. The oil flows into the filter element from the oil inlet hole on the bottom of the body cover. The magnetic unit attached to the crease of the filter paper can absorb the iron powder in the oil due to its strong magnetism, and carry out the second After the first filter, the oil flows into the filter element through the filter paper, the second filter is performed through the filter mesh of the filter paper, and the third filter is performed through the filter screen on the inner periphery of the filter paper, and finally the oil is filtered by the filter paper. The flow port in the center of the core flows out, and the clean engine oil flows out through the outlet hole in the center of the cover, which can filter out impurities.

2. Since the magnetic unit is attached to the crease of the outer periphery of the filter paper, its construction is simple, fast and easy, and the manufacturing cost is relatively reduced. Moreover, the magnetic unit is placed on the filter paper. Even if the magnetic force fades, the iron powder in the oil remains It can be blocked by the filter paper, so that it does not flow directly into the flow port. It can indeed filter the iron powder impurities in the oil, and has excellent filtering effect.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

Fig. 2 is the implementation schematic diagram of the utility model.

Detailed ways:

Referring to Fig. 1, an axial filter core 2 is arranged inside the oil filter body 1 of the present utility model, wherein, the center of the seal 11 at the bottom of the body 1 is provided with an outlet hole 111 for oil to flow out, and an outlet hole 111 is provided on the cover surface. There are several oil inlet holes 112, and the bottom surface of the filter element 2 is provided with a flow port 21 connected with the outlet hole 111 of the body 1. There is a slightly raised annular platform 211 inside the flow port 21, and the annular platform 211 can properly prevent the filter element 2 from Impurities accumulated at the inner bottom enter the outlet hole 111, so that the outflowing engine oil has a better cleanliness. A metal filter screen 22 is arranged around the inner circumference of the filter element 2, and a bent filter paper is arranged around the periphery of the filter screen 22. 23. On the folded surface of the filter paper 23, at least one group of magnetic units 3 with strong magnetism is pasted, and the magnetic units 3 can be evenly distributed in several equal parts at the creases around the filter paper 23. In this embodiment, The example of 12 equal fractions can actually be subdivided into more equal fractions, which can be increased or decreased arbitrarily depending on the place of use, so as to obtain a filter with ideal working performance.

During implementation, referring to Fig. 2, the engine oil is made to flow into the filter core 2 from the engine oil inlet hole 112 on the bottom surface of the cover 11 of the main body 1, and the magnetic unit 3 attached to the crease of the filter paper 23 can be used by the magnetic unit 3 it has. The strong magnetism can absorb the iron powder in the engine oil. After the first filter, the engine oil flows into the filter element 2 through the filter paper 23, and the second filter is performed through the filter mesh of the filter paper 23, and then passes through the filter paper again. 23 After the filter screen 22 on the inner periphery is filtered for the third time, the flow port 21 in the center of the filter element 2 flows out at last, and the clean engine oil flows out through the outlet hole 111 in the center of the cover 11 .

And this magnetic unit 3 is owing to being attached to the crease place of filter paper 23 periphery, its construction is simple and easy, quick and easy, relatively reduces manufacturing cost, and magnetic unit 3 is placed on the filter paper 23 outside, even if magnetic force fades away, in this engine oil The iron powder in the engine oil can still be filtered and blocked by the filter paper 23, so as not to directly flow into the flow port 21, and the iron powder impurity in the oil can be indeed filtered, which has an excellent filtering effect.
