Core-tube-free efficient engine oil filter

Abstract

The invention discloses a core-tube-free efficient engine oil filter. The core-tube-free efficient engine oil filter comprises a filter body with an oil inlet and an oil outlet. The filter body comprises an outer shell and a filter element. The filter element comprises corrugated filter paper, an upper end plate and a lower end plate. The corrugated filter paper is provided with corrugated grooves and comprises a framework layer and filter paper layers. The framework layer comprises multiple metal wire bodies, wherein the multiple metal wire bodies are sequentially and vertically arranged at the fold positions of the corrugated grooves, and the two ends of each metal wire body are higher than the end portions of the inner filter paper layer and the outer filter paper layer. The corrugated filter paper is connected end to end so that cavities can be formed in the inner sides of the corrugated filter paper. The upper end plate is located at the top end of the corrugated filter paper and is fixed to the corrugated filter paper and the outer shell, and the lower end plate is located at the bottom end of the corrugated filter paper and is fixed to the corrugated filter paper and the outer shell. The upper end plate and the lower end plate are provided with avoiding grooves for the wire bodies to be inserted. The overall structure of the core-tube-free efficient engine oil filter is simplified, and the filtering efficiency of the core-tube-free efficient engine oil filter can be effectively increased.

Description

technical field [0001] The invention relates to the technical field of filtration, in particular to a coreless cylinder high-efficiency oil filter. Background technique [0002] The oil filter is located in the engine lubrication system. Its upstream is the oil pump, and its downstream is the various parts in the engine that need to be lubricated. Its function is to filter out harmful impurities in the engine oil from the oil pan, and supply the clean engine oil to the crankshaft, connecting rod, camshaft, supercharger, piston ring and other kinematic pairs to lubricate, cool and clean, thereby Extend the life of these components. [0003] The filter element of the existing oil filter is composed of pleated filter paper and a core cylinder arranged inside the pleated filter paper to support the structure of the pleated filter paper and fix the pleated filter paper and the filter housing, which makes part of the filter surface of the pleated filter paper be covered. The co...

Problems solved by technology

[0003] The filter element of the existing oil filter is composed of pleated filter paper and a core cylinder arranged inside the pleated filter paper to support the structure of the pleated filter paper and fix the pleated filter paper and the filter housing, which makes part of the filter surface of the pleated filter paper be covered. The core barrel blocks the filter work, which limits the filter area of ​​the pleated filter paper and weakens its filter efficiency, which needs to be improved urgently
