In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor Under, the structure that can also be shown according to these attached drawings obtains other attached drawings.

Fig. 1 is the structural schematic diagram of the utility model machine oil filter core preferred embodiment.

The embodiments will be further described with reference to the accompanying drawings for the realization, functional characteristics and advantage of the utility model aim.

Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than all Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise Lower obtained every other embodiment, shall fall within the protection scope of the present invention.

It is to be appreciated that the directional instruction (such as up, down, left, right, before and after ...) of institute in the utility model embodiment It is only used for explaining relative position relation, the motion conditions etc. under a certain particular pose (as shown in the picture) between each component, such as When the fruit particular pose changes, then directionality instruction also correspondingly changes correspondingly.

The utility model proposes a kind of machine oil filter cores, in engine, being filtered to machine oil.

Referring to Fig.1, the machine oil filter core of the present embodiment, including cylindric filter cylinder 10 and it is fixed on the two of 10 both ends of filter cylinder Annular end cap 20；Wherein, which is that the be serrated filter paper of folding is wound, i.e., filter paper is first repetitively folded shape back and forth It is fixed as cylindrical shape at zigzag, then by jagged filter paper coiling, then forms the filter cylinder 10.On filter cylinder 10, tip is inwardly Sawtooth be inside sawtooth 11, the sawtooth of tip outwardly then be outside sawtooth 12；Each sawtooth on filter cylinder 10 can be identical, Can be different, the inside sawtooth 11 and outside sawtooth 12 of the preferred filter cylinder of the present embodiment 10 are all using being uniformly arranged.The filter cylinder 10 The tooth top of inside sawtooth 11 be located between the inside and outside edge of the annular end cap 20, the outside sawtooth 12 of the filter cylinder 10 Tooth top is located at the outer peripheral outside of the annular end cap 20, that is, there is no the ends of all covering filter cylinders 10 for annular end cap 20 Face, but the only inner round portion of 10 end face of covering filter cylinder.In the present embodiment, the sealing of annular end cap 20 covers 10 end face of filter cylinder The region surrounded with the outer edge of the part of its face, and each outside sawtooth 12 and the annular end cap 20 of filter cylinder 10 is then It is all made of hot melt adhesive sealing, covers the both ends of the inner space of filter cylinder 10 in this way, being realized by annular end cap 20 and hot melt adhesive. When to oil filtration, machine oil is penetrated into from the outer surface of filter cylinder 10 in filter cylinder 10 machine oil filter core, then the machine oil in filter cylinder 10 It is flowed out from the outlet on annular end cap 20；Since there is no the end face of all covering filter cylinders 10, the ends of filter cylinder 10 for annular end cap 20 Machine oil can also not permeated by the part that annular end cap 20 covers on face, i.e. the oil inlet area of filter cylinder 10 increases, in this way, then filtering The oil inlet quantity of cylinder 10 increases, to the filter efficiency higher of machine oil.

The present embodiment technical solution covers the end face of filter cylinder 10 by using 20 part of annular end cap, by 10 end face of filter cylinder It is not sealed by hot melt adhesive by the part that annular end cap 20 covers, in this way, the portion sealed by hot melt adhesive on the end face of filter cylinder 10 Dividing can be used for machine oil oil inlet so that the whole oil inlet area of machine oil filter core increases, and improves the oil inlet quantity of machine oil filter core, drops The oil inlet resistance of low entirety machine oil filter core, and then the filter efficiency of machine oil filter core is promoted；In addition, since annular end cap 20 is without complete Portion covers the end face of filter cylinder 10, therefore saves the material of annular end cap 20, reduces cost of material.

Further, in this embodiment being embedded in ring using the sealing of the part of filter cylinder 10 and 20 face of the annular end cap Mode in shape end cap 20 realizes that annular end cap 20 is fixed with filter cylinder 10 and annular end cap 20 covers the part of filter cylinder 10.This The preferred annular end cap 20 of embodiment can be used hot plate welding processing technology and realized filter cylinder in this way using the end cap of hot melt adhesive nylon material 10 in the partial embedding annular end cap 20 of 20 face of annular end cap.

In the present embodiment, the filter paper of the filter cylinder 10 preferably uses high corrugation wood pulp paper, in the wood pulp of the high corrugation wood pulp paper It is mixed into 30% glass and is cured using phenolic resin impregnation.Wherein, the thickness of filter paper is 0.92~0.98mm, on the filter paper Corrugation depth be 0.38~0.43mm, air permeability 640~660L/ ㎡ * S of the filter paper, the average pore size of the filter paper is 75~85 μm.Specifically, the present embodiment preferably uses：The thickness of filter paper is 0.95mm, and the corrugation depth on the filter paper is The average pore size of 0.4mm, the air permeability 650L/ ㎡ * S of the filter paper, the filter paper are 80 μm；It is made of the filter paper of the specification Filter cylinder 10,60% is more than to the filter efficiency of 20 μm of impurity, dust containing capacity is more than 6g, and original resistance is less than 7KPa so that machine The dust containing capacity of oily filter core is high, oil inlet resistance is low.

Further, in this embodiment being less than 15 degree using the angle of the outside sawtooth 12 of filter cylinder 10, in this way, filter cylinder 10 12 quantity of outside sawtooth can be arranged enough, keep the filter area of filter cylinder 10 sufficiently large, oil inlet quantity bigger, and to filter cylinder 10 The hot melt adhesive sealing of end face is more convenient.

The utility model also proposes a kind of oil filter, which includes machine oil filter core, the machine oil filter core Concrete structure is with reference to above-described embodiment；Since this oil filter uses whole technical solutions of above-mentioned all embodiments, because This at least has all advantageous effects caused by the technical solution of above-described embodiment, and this is no longer going to repeat them.In addition, this reality A kind of engine including the oil filter is also proposed with novel.

The above is only the preferred embodiment of the present invention, and it does not limit the scope of the patent of the present invention, It is every under the inventive concept of the utility model, equivalent structure made based on the specification and figures of the utility model becomes It changes, or directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
