Description

A kind of oil filter

Technical field

The utility model relates to automobile maintenance fields, and in particular to a kind of oil filter.

Background technique

Oil filter, also known as engine oil grid, for removing the dust in machine oil, metallic particles, carbon precipitates and coal smoke The impurity such as grain protect engine.

Currently, the ownership of cast iron engine is still very huge although there is all-aluminium engine.Cast iron engine Metallic particles be iron powder, therefore, there has been proposed using magnet adsorb iron powder, further increase machine oil filtration result, reduce Engine scuffing.

There are mainly two types of existing magnet mounting means: 1, external is mounted directly magnet block in filter box in vitro, It, which has, is easily installed and advantage that magnet is reusable, but since itself shake, vehicle such as jolt at the factors, exists and fall off Risk may damage other components in enging cabin；2, built-in, i.e., enter inside oil filter close to sump oil Magnet is arranged in mouth or filter core center, and when being arranged at sump oil inlet, iron powder can largely adsorb accumulation here, and work as and add When fast, machine oil flow velocity can increase moment, wash away to the iron powder of sump oil inlet accumulation, be easy to cause the iron powder of collection again Into engine；When being arranged at filter core center, in addition to aforementioned machine oil washes away factor, it is also easy to cause to lead because iron powder blocks The circulating resistance of cause increases, and influences normal engine oil supplying.

Utility model content

The purpose of this utility model is to provide a kind of oil filter.

To achieve the above object, the utility model uses following technical scheme:

Oil filter, including shell, capping, filter core cover board and element kit, the element kit include filter element upper cover, Filter core and filter core lower cover, the filter core lower cover correspond in the annular region of the filter core, and along the circumferential direction array has several recessed Slot is inlaid with magnet block in each groove.

Preferably, the slot bottom of the groove is machined with through-hole.

Preferably, the groove is round recessed, and quantity is 2-3, and the outer diameter of the magnet block is 6-8mm, is highly 2-6mm。

It preferably, further include magnet ring；The lower semisection of the shell is equipped with one and inside contracts the annular installation position formed, institute by shell Magnet ring is stated to be mounted on the annular installation position；The cross section of the magnet ring is in up-small and down-big right-angled trapezium shape, the right angle Trapezoidal upper bottom is 1-3mm, and the bottom of the right-angled trapezium is 2-3mm with the difference at upper bottom, and the height of the right-angled trapezium is 15-20mm。

Preferably, the magnet ring includes left semi-ring and right semi-ring, one end of one end of the left semi-ring and the right semi-ring Hingedly, the other end of the other end of the left semi-ring and the right semi-ring is realized by button hole and fastener and is connected, the magnet ring Inside is equipped with rubber layer so that the magnet ring keeps tensioning state.

Preferably, rubber layer is arranged in several segments interval.

Preferably, the magnet ring is rubber magnet ring.

After adopting the above technical scheme, the utility model compared with the background art, has the advantages that

1, several magnet blocks are arranged in filter core lower cover in the utility model, and the influence to oil filter cost is very little, Simultaneously as the injection of machine oil is moved towards, in conjunction with the influence of iron powder self gravity, iron powder is easier in filter core lower cover upper surface and filter The aggregation of core lower cover lower end surface, adsorption effect is good, meanwhile, it reduces machine oil under accelerated condition and influence is washed away on iron powder.

2, the utility model is also provided with magnet ring, and the section of the magnet ring uses up-small and down-big design, so that its underpart The magnetic force for dividing magnetic force to be higher than upper part, so that iron powder of its absorption is easier to shift to downside, with the magnet block covered under filter core Cooperation, by iron powder primary attachment in underside area.

3, the utility model devises two kinds of magnet rings, and one kind is hard magnet ring, by the way of button hole and fastener snapping It is fixed on shell, and rubber layer is set in the inside of magnet ring, between on the one hand rubber layer being utilized to fill between magnet ring and shell On the other hand gap is realized the tensioning of magnet ring using the deformability of rubber layer, had not only played the advantage of tool-free dismounting, but also make Fastener it is simple and reliable for structure；Another kind is rubber magnet ring, is directly socketed on shell, simple and reliable.

Embodiment 1

It please refers to shown in Fig. 1-Fig. 3, the utility model discloses a kind of oil filter comprising shell 1, capping 2, filter Core cover plate 3 and element kit, the element kit include filter element upper cover 4, filter core 5 and filter core lower cover 6.Filter core lower cover 6 corresponds to In the annular region 61 of filter core 5, along the circumferential direction array has several grooves 62, is inlaid with magnet block 63 in each groove.

In order to preferably adsorb to the iron powder for being deposited on housing bottom, the slot bottom of groove 62 is machined with through-hole, thus So that the lower end surface of magnet 63 is exposed.

Groove 63 is round recessed, passes through punch forming.The utility model is by the way that experimental results demonstrate be in the drain period When between 5000 kilometers -10000 kilometers, its quantity of magnet block (ndfeb magnet) is 2-3, and the outer diameter of magnet block 63 is preferred It is highly 2-6mm for 6-8mm, has not only can satisfy absorption demand, but also can utmostly reduce the dosage of magnet block.

For the adsorption effect for further promoting iron powder, the utility model is additionally provided with magnet ring 7.The lower semisection of shell 1 is equipped with one The annular installation position that (spinning process or necking down process) is formed is inside contracted by shell, magnet ring 7 is mounted on the annular installation position.This In embodiment, the cross section of magnet ring 7 is in up-small and down-big right-angled trapezium shape, it is preferable that the upper bottom of the right-angled trapezium is 1- 3mm, the bottom of the right-angled trapezium are 2-3mm with the difference at upper bottom, and the height of the right-angled trapezium is 15-20mm.

Magnet ring 7 includes left semi-ring 71 and right semi-ring 72, and one end of Zuo Banhuan 71 and one end of right semi-ring 72 are hinged, Zuo Banhuan The other end of 71 other end and right semi-ring 72 is realized by button hole 711 and fastener 721 and is connected, in this way, when the outside to magnet ring 7 Apply curable grip, the deformation of rubber layer 73 can be oppressed, so that button hole 711 is aligned with fastener 721, looses one's grip and remove curable grip Afterwards, rubber layer 73 is restored so that magnet ring 7 keeps tensioning state, so that button hole 711 is reliably connected with fastener 721.For drop Low required curable grip, rubber layer 73 are arranged in several segments interval.

Embodiment 2

Please refer to shown in Fig. 5, the present embodiment difference from example 1 is that magnet ring 7 difference, in the present embodiment, Magnet ring 7 is rubber magnet ring, the advantage is that installation is more reliable, cost is lower, but its available magnetic force is less than 1 institute of embodiment The magnetic force for showing structure, the scene shorter suitable for mileage travelled in the unit drain period.

The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in Change or replacement, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should It is subject to the protection scope in claims.
