AI Technical Summary
Technical Problem
The filter paper of the existing oil filter is cylindrical, resulting in poor filtering efficiency.
Method used
Adopting inclined filter paper and automatic pressure regulating structure, the oil output is adjusted through the oil inlet hole design and pressure ball, which improves the filtering efficiency and automatic pressure regulating function.
Benefits of technology
The filtration speed and efficiency are improved without affecting the filtration effect, and automatic pressure regulation is achieved, which expands the scope of application.

Abstract
According to the technical scheme, the automatic pressure regulating type engine oil filter comprises a protective cylinder, an oil outlet pipe is inserted in the middle of the interior of the protective cylinder in a sealed mode, a plurality of oil inlet holes located in the periphery of the oil outlet pipe are formed in the top of the protective cylinder at equal angles, and a filter cylinder is fixed to the middle of the interior of the protective cylinder. The oil outlet pipe extends into the bottom of the filter cartridge, filter paper is inserted outside the filter cartridge, the upper portion of the filter paper is inclined, the outer diameter of the top of the filter paper is smaller than that of the lower portion of the filter paper, the circle centers of the oil inlet holes are located on the outer diameter of the lower portion of the filter paper, and the radius of the oil inlet holes is equal to the outer diameter difference of the top and the lower portion of the filter paper. Due to the fact that the inclined portion of the upper portion of the filter paper and the circle center of the oil outlet are located on the outer diameter of the lower portion of the filter paper, part of engine oil can be directly filtered into the filter cylinder through impact force generated by falling through the inclined portion when the engine oil enters the protective cylinder through the oil inlet, and the filtering speed is increased under the condition that the filtering effect is not affected.
