Problems solved by technology

However, since the magnets are concentrated at the oil outlet, they cannot absorb all the metal powder in the high-speed flowing oil at one time, and the filtration performance is not very good.

[0027] Embodiment 1: Referring to Fig. 1, the disposable two-stage filter magnetic oil filter in the figure includes a barrel-shaped housing 9, an upper cover 2, a combined ring magnet 5, a support spring 10, a filter element 7, and a seal, and the filter element 7 is located at In the housing 9, the upper cover 2 is airtightly connected with the housing 9, the upper cover 2 is provided with oil inlet and outlet ports, the filter element 7 is provided with a filter element support 8 matching its shape, and the filter element support 8 is provided with There are evenly distributed oil holes, the lower end surface of the filter element support 8 is closed, and the upper end surface is provided with an oil outlet matching the oil outlet of the upper cover 2, the support spring 10 is located at the lower part of the filter element support frame 8, and the filter element 7 is provided with a Isolation cylinder 6, the exterior of the upper end of the isolation cylinder 6 is kept seal...

Embodiment 2

[0029] Embodiment 2: Referring to Fig. 2, Embodiment 2 is basically the same as Embodiment 1. The same symbols in the figure represent the same meaning, and the same parts will not be repeated. The difference is that in Embodiment 2, only the inner wall of the housing 9 is provided with a Matching combination ring magnet5.

Embodiment 3

[0030] Embodiment 3: Referring to Fig. 3, Embodiment 3 is basically the same as Embodiment 1. In the figure, the same representative meanings are the same, and the similarities will not be repeated. The difference is that only the outer wall of the cylinder 6 is isolated in Embodiment 3 A combined ring magnet 5 matching it is provided.

Abstract

The disposable double stage magnetic machine oil filter has two filtering rooms, including one magnetic filtering room and one filter paper filtering room, formed inside the casing and one isolating cylinder inside the casing to guide the machine oil to pass successively through these two filtering rooms. The present invention has increased area and time for machine oil to contact with the magnet, raised metal particle filtering effect, no jamming in the filter paper, long service life of the filter and excellent protection on the engine.

Description

1. Technical field [0001] The invention relates to an engine oil filter, in particular to a disposable two-stage filter magnetic engine oil filter. 2. Background technology [0002] In the past, the filter elements of the oil filters used in various engines used filter paper as the filter medium. This filtering method is more effective for larger particles, but the filtration and purification of micron-sized particles is negligible. However, in a high-speed running engine, the mutual wear between the piston ring and the cylinder wall is inevitable, and most of the metal particles produced by this wear are in the micron order. Therefore, the existing engine oil filter has low efficiency in purifying micron-sized metal particles and cannot effectively remove them. For this reason, in recent years, someone has used a built-in magnetic adsorption method to solve the above problems. As CN01234155 patent discloses a solution, a ring-shaped magnet with holes is arranged at the oi...
