Description

Oil filter of perpendicular installation

Technical Field

The invention relates to the technical field of automobile parts, in particular to a vertically-installed oil filter.

Background

The engine oil filter, also known as the machine oil check, is used for getting rid of impurity such as dust, metal particle, carbon deposit and soot particle in the machine oil, and in the engine working process, metal abrasive dust, the carbon deposit and the colloidal precipitate that oxidize under the high temperature, water etc. constantly mix into lubricating oil, and oil filter's effect is just filtering these mechanical impurity and colloid, keeps treating the cleanness of lubricating oil, prolongs its life to protect the engine, its theory of operation is: under normal conditions, machine oil filters through the paper filter core, and when the paper filter core was big at cold-start machine oil viscosity or the paper filter core was blocked up partially or totally, the bypass valve was opened, and direct inside the machine oil pump that will not filter was gone into to the generator.

However, the oil filter used in the prior art still has the following problems in the actual working process: firstly, because the oil filter intercepts and filters harmful impurities in the engine oil by means of tiny core holes on filter paper, the impurities filtered by the filter element are gradually increased along with the lapse of service time, so that the permeability of the filter is gradually reduced, but the existing filter does not have a corresponding reminding function and cannot be found and replaced by a user in time, and the failure of the filter paper often occurs in the driving process of an automobile, so that a driver cannot process the filter paper at the first time, and the engine oil is easy to enter the engine directly from a bypass valve; secondly, although the bottom of the paper filter element of the existing filter is provided with the bypass valve, the direct oil flow channel is designed for ensuring that the engine oil can smoothly circulate back to the engine when the viscosity of the engine oil is high during cold start or the paper filter element is partially or completely blocked, when the bypass valve is opened under the pressure of the oil pump, the engine oil which circulates back to the engine through the bypass valve cannot be filtered by the paper filter element, and large granular impurities which are filtered out by the paper filter element can be flushed back to the engine through the bypass valve again, so that uninterrupted secondary abrasion is brought to the engine, and great harm is caused to the engine.

As shown in fig. 6, the clamping groove 28 is a sector structure with a large inside and a small outside, the upper end of the clamping rod 26 is clamped inside the clamping groove 28 in the initial state, the bottom end of the clamping rod 26 extends into the inside of the connecting pipe 22 and is positioned on one side of the joint of the top block 25 and the supporting spring 24, and the clamping rod 26 can compress the cleaning disc 27 in the effect of the torsion spring in the initial state and is matched with the clamping groove of the sector structure to avoid the direct floating of the cleaning disc 27 under the effect of self buoyancy.

As shown in fig. 7 and 8, the cleaning disc 27 is made of a rigid foam plate with density smaller than that of engine oil, the inner profile of the cleaning disc 27 is matched with the outer profile of the filter paper 12, and bristles are arranged on the inner side of the cleaning disc 27, so that impurities adhered to the outer surface of the filter paper 12 can be better and comprehensively scraped off, the working time of the filter paper 12 is prolonged, and a driver can conveniently maintain and replace the engine oil filter.

The working principle of the oil filter is that after the oil filter is vertically installed, when the oil filter works normally, engine oil enters from the oil inlet 4, passes through the oil pipe 7 after being filtered by filter paper and enters an engine from the oil outlet 3, meanwhile, the filtered engine oil enters into the connecting cavity 13 from the return pipe 14, when more impurities appear on the surface of the filter paper and cause the primary deterioration of the filtering effect, the oil pressure can extrude the elastic rubber membrane 19 to deform a small amount towards the middle of the connecting cavity 13, the clean engine oil in the connecting cavity 13 transmits the pressure to the valve core of the bypass valve 11, so that the valve core generates small displacement upwards, the connecting rod 16 and the supporting rod 17 drive the supporting frame 18 to move upwards with the same displacement, so that the supporting frame 18 can extrude the air in the annular cavity 21, the top block 25 moves towards one side of the supporting spring 24, the clamping rod 26 can be pushed to overcome the elasticity of the torsion spring to deflect, and the cleaning disc 27 is separated from the limitation of the clamping rod 26, the filter paper moves upwards under the action of self buoyancy, impurities on the outer side of the filter paper 12 can be cleaned and scraped off through the bristles on the inner side of the cleaning disc 27 in the moving process, the filtering performance of the filter paper can be improved for a short time, the running time of an automobile is prolonged, and the situation that unfiltered engine oil directly enters the engine from a bypass valve to cause damage to the engine is avoided;

when the automobile continuously runs and the filter paper 12 is blocked by impurities, the engine oil pressure mainly acts on the elastic rubber membrane 19, the inner side of the elastic rubber membrane 19 expands and is extruded by clean engine oil in the connecting cavity 13 to open the bypass valve 11, as shown in fig. 5, when the valve core of the bypass valve 11 is opened upwards, the connecting rod 16 and the support rod 17 drive the support frame 18 to move upwards synchronously, so that the filter element 20 at the bottom of the support frame 18 rises into an oil path connected between the connecting cavity 13 and the shell 1, the engine oil entering the engine through the bypass valve 11 can be filtered by the filter element 20, and the engine damage caused by the fact that the engine oil which is not filtered directly enters the engine is further avoided; and when support frame 18 rose, can continuously extrude the inside air of annular cavity 21, can make a sound when the in-process of its inside air from outlet duct 23 exhaust through the steam whistle, remind vehicle driver oil filter paper 12 oil strain to be in extremely low state, and used reserve filter core 20 to carry out the oil filtration, should avoid in time going for a long time, need in time maintain oil filter.
