Detailed Description

The technical scheme of the utility model is further described below through the attached drawings and the embodiments.

Examples

As shown in the figure, a prefilter type oil filter comprises a prefilter 1, a filter chamber 2 and a filter element 21, wherein the prefilter 1 and the filter chamber 2 are cylindrical. The prefilter 1 is arranged on an oil inlet of the filter chamber 2, an oil outlet 23 is arranged at the bottom of the side wall of the filter chamber 2, after scrap iron is screened out by the prefilter 1, oil continuously enters the filter core 21 for filtering, and the filtered oil is discharged from the oil outlet 23. The filter element 21 is a paper filter element.

The prefilter 1 comprises an outer housing 11 and a blocking ball 12, the radius of the blocking ball 12 being larger than the radius of the oil inlet of the outer housing 11, so that oil entering the outer housing 11 will directly impinge on the blocking ball 12. The middle inner wall of the outer shell 11 and the surface of the blocking ball 12 are both provided with a magnetic attraction layer 15 for adsorbing scrap iron in oil. The separation ball 12 is arranged in the connecting ring 17, the separation ball 12 is fixedly connected with the connecting ring 17 through a plurality of radiation strips 13, the radiation strips 13 are uniformly distributed around the separation ball 12, and gaps among the radiation strips 13 need to ensure that oil can smoothly pass through. The connecting ring 17 is clamped with the bayonet 14 on the inner wall of the middle part of the outer shell 11, the bayonet is triangular, and is matched with the shape of the outer surface of the connecting ring 17, so that the installation is simple, and the blocking ball 12 is prevented from falling off.

An inner thread is arranged on the inner wall of the bottom of the outer shell 11, and the outer shell 11 is in threaded connection with the outer wall of the oil inlet of the filtering chamber 2 through the inner thread. The anti-leakage rubber ring 16 is arranged above the internal thread, and the anti-leakage rubber ring 16 is pressed on the top surface of the filter element 21 to prevent oil from leaking from a gap between the prefilter 1 and the filter element 21.

The filter cartridge 21 is mounted within the filter chamber 2. The inner wall of the oil inlet of the filter chamber 2 is in threaded connection with the top of the outer wall of the filter element 21, a clamping ring 22 is arranged on the inner wall of the bottom of the filter chamber 2, and the bottom of the filter element 21 is arranged in the clamping ring 22 and used for fixing the position of the filter element 21. The top surface of the oil inlet of the filtering chamber 2 is also provided with a leakage-proof rubber ring 16 for preventing oil from leaking from a gap between the filtering core 21 and the filtering chamber 2.

Therefore, the prefilter type oil filter adopting the structure adsorbs scrap iron impurities in oil through the blocking ball 12 in the prefilter 1 and the magnetic attraction layer 15 on the outer shell 11, the impurities with larger volume enter the filter chamber 2 and are further filtered by the filter core 21, the filtered oil is discharged through the oil outlet 23, and the prefilter 1 and the filter core 21 are detachably connected with the filter chamber 2, so that the prefilter type oil filter is convenient to replace, the filtering effect is enhanced, and the damage of tiny scrap iron in the oil to the structure of an automobile engine is reduced.
