Description

A kind of automobile oil filter

Technical field

The utility model is related to automobile engine oil filtration art, more particularly to a kind of automobile oil filter.

Background technology

Oil filter is also known as machine filter, in engine lubrication system.The upstream of machine filter is lubricating oil pump, and downstream is to start Each parts lubricated are needed in machine.Machine filter in the machine oil of oil sump objectionable impurities filter out, with clean machine oil The kinematic pairs such as bent axle, connecting rod, camshaft, booster, piston ring are supplied, lubrication, cooling, cleaning action are played, so as to extend this The service life of a little parts.

Containing large granular impurities such as iron filings, greasy filth, particulate matters in machine oil, also there are some little particle impurity, so as to shadow Ringing the lubricating action of machine oil causes the power dropping of engine, accelerates the abrasion of parts, due to filter one of the prior art As only one of non-woven fabrics be filtered, can so cause either large granular impurity or little particle impurity all be in nonwoven It is filtered on cloth, usage time can cause oil filtration speed slow after growing, poor filtration effect, and service life is low.

Utility model content

The purpose of this utility model be to provide one kind can layered filtration size particles impurity, good filtration effect, service life Long automobile oil filter.

To achieve these goals, the utility model provides following technical solution：

A kind of automobile oil filter, including upper end cover, by the filter core of the longitudinal folding hollow cylindrical formed of non-woven fabrics And bottom end cover, the upper end cover are mounted on filter core upper end, the bottom end cover is mounted on filter core lower end, is also set up in the upper end cover For fastening buckling parts on the engine, the oil outlet of the upper end cover is provided with the first rubber plug, is set in the bottom end cover The second rubber plug is equipped with, the filter core periphery is provided with the sponge ring of circle filtering large granular impurity at upper end cover.

Further, the filter core includes nonwoven layer and pin hole layer of cloth, and the pin hole layer of cloth is arranged on the outer layer of filter core, The nonwoven layer is arranged on the internal layer of filter core.

Further, continuous winding is pasted with cotton thread to the circumferential outer surface from lower to upper.

Further, the semi-section of first rubber plug is Y-shaped.

Further, the semi-section of second rubber plug is C fonts.

The beneficial effects of the utility model are：

The utility model filters the sponge ring of large granular impurity by being provided with a circle at upper end cover in filter core periphery, So machine oil first passes through the filtering that sponge ring carries out large granular impurity, then enters back into filter core and be filtered into fashionable, this Sample can filter by different level, first cross large granular impurity on sponge ring, then by the small impurity of filter element filtering, greatly improve Filter efficiency, good filtration effect also extend service life.

Specific embodiment

The utility model is further described below in conjunction with attached drawing：

A kind of automobile oil filter as described in Fig. 1 to Fig. 3 is formed including upper end cover 1, by non-woven fabrics is longitudinal folding The filter core 2 of hollow cylindrical and bottom end cover 3, the upper end cover 1 are mounted on 2 upper end of filter core, and the bottom end cover 3 is mounted on filter core 2 Lower end, the buckling parts 4 for fastening on the engine is also set up in the upper end cover 1, and the oil outlet of the upper end cover 1 is set There is the first rubber plug 5, the second rubber plug 6 is provided in the bottom end cover 3,2 periphery of filter core is provided with a circle at upper end cover Filter the sponge ring 7 of large granular impurity.

Second embodiment, as shown in Fig. 4 to 6, the filter core 2 includes nonwoven layer 21 and pin hole layer of cloth 22, described Pin hole layer of cloth 22 is arranged on the outer layer of filter core 2, and the nonwoven layer 21 is arranged on the internal layer of filter core 2, and pin hole layer of cloth 22 can hinder The impurity of gear medium grain is filtered, then the impurity of filter small particles, further can carry out layered filtration to particle, Greatly improve the rate of filtration and filter effect.

3rd embodiment, as shown in Figure 9, continuous winding is pasted with cotton thread 8 to the circumferential outer surface from lower to upper, can To greatly strengthen the non-deformability of filter core 2.

Further, as shown in Figure 8, the semi-section of first rubber plug 5 is Y-shaped, can be with including two flange collars Sealing effect is improved, places leakage.

Further, as shown in Figure 7, the semi-section of second rubber plug 6 is C fonts, can improve sealing effect, put Put leakage.

Operation principle is：

Filter is to be mounted on by upper end cover 1 and bottom end cover 3 in engine first, and the filter of the present embodiment is with starting Machine formed an oil inlet passage, oil from oil inlet passage enter, large granular impurity is filtered out by sponge ring 7 first, then proceed into Enter, then entered by filter core 2 and bottom end cover 3 in filter core 2, finally flowed out upwards from upper end cover 1 out of filter core 2.This practicality It is new by be provided in 2 periphery of filter core at upper end cover 1 circle filter large granular impurity sponge ring 7, such machine oil into It is fashionable, the filtering that sponge ring 7 carries out large granular impurity is first passed through, then enters back into filter core 2 and is filtered, can so divide Level filters, and first crosses large granular impurity on sponge ring 7, then by the small impurity of filter element filtering, greatly improves filtering effect Rate, good filtration effect also extend service life.

The above is not limit the technical scope of the present invention, all according to the utility model technical spirit To any modification, equivalent variations and modification that above embodiment is made, the model of the technical solution of the utility model is still fallen within In enclosing.
