Description

Automobile oil filter

Technical Field

The invention relates to the field of automobile filter equipment, in particular to an automobile oil filter.

Background

The existing oil filter generally filters impurities through a filter element, when filter paper is used for a period of time, the filter paper is gradually blocked by impurities in engine oil to lose oil filtering and oil supply functions, in order to ensure smooth oil supply, most of the oil filters are provided with a bypass valve structure, and when the filter element is blocked, the bypass valve is opened under the action of oil pressure to directly supply unfiltered engine oil so as to ensure that an engine can maintain normal operation in emergency.

However, the surface of the conventional oil filter is blocked by dirt along with the increase of the working time, so that the filtering effect is reduced.

Disclosure of Invention

The invention mainly aims to provide an automobile oil filter which can effectively solve the problems in the background technology.

In order to achieve the purpose, the invention adopts the technical scheme that:

an automobile oil filter comprises a shell, a dirty oil inlet, a central pipe and a filter element, wherein the inner surface of the shell is divided into a heat filtering area and a blocking filtering area from top to bottom by a partition plate, and the central pipe penetrates through the partition plate and extends to a position close to the bottom of the inner surface of the shell;

the outer surface of the central pipe is sleeved with filter elements at the positions above and below the partition plate;

a one-way valve is arranged at the position, between the outer surface of the filter element and the inner surface of the shell, of the outer surface of the partition plate;

an automatic cleaning device is arranged on the inner wall of the shell at the position of the filter element;

automatic cleaning device includes the fixed foot of establishing along shell inner wall circumference interval row, one side that fixed foot is close to the filter core is provided with the brush body pole, the one end that the brush body pole is close to the filter core is provided with the cleaning brush, gets into hot filtering area through machine oil and can assault the cleaning brush and drive its swing to clear up the filter core surface, in order to improve its life.

Furthermore, the fixed feet are arranged at intervals along the Y-axis direction, the inner surfaces of the fixed feet are rotatably connected with the brush body rods, the two adjacent brush body rods are connected through springs, the inner surfaces of the fixed feet closest to the partition plate are fixedly connected with the brush body rods, engine oil enters the heat filtering area to impact the brush body rods, and linkage and swing effects are generated through the springs, so that the cleaning brush can clean the surface of the filter element in a vertical reciprocating mode, and the cleaning purpose is achieved.

Furthermore, the springs are arranged in a staggered mode, so that the swing amplitude of two adjacent brush body rods is inconsistent, and the brush body rods can swing continuously.

Furthermore, a slope is arranged at the position, between the central pipe and the one-way valve, of the top of the partition plate, and oil in the hot filtering area can flow out of the one-way valve.

Furthermore, the position that the center tube internal surface is close to the subregion board is fixedly connected with the check valve, avoids during normal work oil inflow to be located the jam filtering area of subregion board below, provides its normal life.

Furthermore, a plurality of oil inlets are formed in the positions, above and below the partition plate, of the outer surface of the central pipe, so that normal circulation of engine oil is guaranteed.

The working principle and the beneficial effects are as follows: get into hot filtering area through machine oil and can strike the cleaning brush and drive its swing to clear up the filter core surface, in order to improve its life.

(1) Arrange along Y axle direction interval through fixed foot, the internal surface and the brush body pole of fixed foot rotate to be connected, through spring coupling between two adjacent brush body poles, with the internal surface and the brush body pole fixed connection of the nearest fixed foot of subregion board distance, machine oil gets into hot filtering area and strikes brush body pole to produce linkage and wobbling effect through the spring, make the clearance brush carry out reciprocal clearance from top to bottom to the filter core surface, in order to reach the clearance purpose.

(2) Through the dislocation arrangement of the springs, the swing amplitudes of two adjacent brush body rods are inconsistent, so that the brush body rods can swing continuously.
