Specific embodiment

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the present utility model, rather than all Embodiment.Embodiment in based on this utility model, those of ordinary skill in the art are not making creative work premise Lower obtained every other embodiment, belongs to the scope of this utility model protection.

The utility model proposes a kind of machine oil filter core, is one of main member of oil filter, it is mainly used in various On electromotor, it is the impurity such as dust, metallic particles, carbon precipitates and coal soot that electromotor is filtered in machine oil, so as to keep The cleaning of machine oil, the useful life for extending machine oil protect electromotor.

As shown in Figure 1 to Figure 3, in the present embodiment, the machine oil filter core 10 include cylindrical shape filter element body 11, can mistake The annular filter cotton pad 13 of filter infiltration machine oil, and the two end cap 12 at filter element two ends is separately fixed at, have and filter on end cap 12 The coaxial through hole 121 of core body 11；Annular filter cotton pad 13 is fixed on end cap 12 back in the one side of filter element body 11, and with logical Hole 121 is coaxial；Internal diameter of the internal diameter of annular filter cotton pad 13 less than through hole 121.In the present embodiment, end cap 12 is annular in shape, and holds The barrel two ends of filter element body 11 are sealed by the external diameter of lid 12 more than the external diameter of filter element body 11.

When the machine oil filter core 10 of the present embodiment is in oil filter, machine oil filter core 10 is enclosed within assembly central canal 20 On, two annular filter cotton pads 13 cover the two ends of assembly central canal 20 respectively, wrap the periphery wall of assembly central canal 20, make assembly Radial seal is kept between central canal 20 and end cap 12, it is ensured that the sealing that assembly central canal 20 is coordinated with machine oil filter core 10.Adopt When used with the oil filter of the present embodiment machine oil filter core 10 on the engine, under normal circumstances, machine oil is through filter element body 11 Enter inside filter element body 11 after filtration, then electromotor is flowed out to through assembly central canal 20；Long between when deployed, filter element sheet Body 11 is blocked, a large amount of machine oil cannot from the filter paper barrel of filter element body 11 penetrate into 11 inside of filter element body when, machine oil can be with Filter to penetrate into the inside of filter element body 11 through annular filter cotton pad 13, then flow out in electromotor from assembly central canal 20, The setting of such annular filter cotton pad 13, increases oil filter and the machine oil of electromotor is supplied, improve electromotor in filter When core body 11 is blocked, the insufficient problem of machine oil, it is therefore prevented that the damage of electromotor.

Further, the end cap 12 of the present embodiment adopts plastic cement end cap, the end seal of filter element body 11 to be embedded in end cap In 12.Its inline operations mode can be：After ring plastic cement end cap 12 to be heated softening, then the end for making filter element body 11 A part in ring plastic cement end cap 12 is clamp-oned, is then cooled down；Or by arranging and filter element sheet on ring plastic cement end cap 12 The draw-in groove of the end interference fit of body 11, the end seal of filter element body 11 are clamped in the draw-in groove；Etc..Filter element body 11 End is embedded in ring plastic cement end cap 12 by sealing and is fixed with ring plastic cement end cap 12, so without the need for being entered by bonding agent Row is fixed, and the problems such as avoid the uniform difficult control of bonding agent coating, the sealing difference that bonding is loosely caused, and avoids bonding Excessive glue that agent is caused, the problems such as emit glue, it is ensured that the outward appearance of machine oil filter core 10 clean and tidy.

The present embodiment adopt the depth bounds that the end of filter element body 11 is embedded in ring plastic cement end cap 12 for 0.9～ 1.2mm.In the embedded depth bounds of here, can preferably ensure the sealing between ring plastic cement end cap 12 and filter element body 11 Property and fastness.

Specifically, in the present embodiment, the end of preferred filter element body 11 is to incorporate in end cap by iron plate welding procedure is embedded In 12.Hot plate welding process operating procedure is substantially：It is heated to starting to melt by end cap 12 by hot plate first；Then heat is removed Plate, the end and end cap 12 for making filter element body 11 extrude welding under pressure state；After the depth of weld and weld interval is reached, Cool down end cap 12, then obtain that filter element body 11 is embedded to be dissolved in end cap 12.

Specifically, the present embodiment annular filter cotton pad 13 is preferably weldingly fixed on end cap 12 by the way of welding.When So, annular filter cotton pad 13 can also be fixed on end cap 12, for example using other fixed forms, using bonding agent bonding.

Further, in the present embodiment, the internal diameter size of annular filter cotton pad 13 from less than the internal diameter of through hole 121 by 4～ 8mm, with the premise of annular filter cotton pad 13 and 20 fitted seal of assembly central canal is ensured so that machine oil can pass through annular The amount for filtering the infiltration of cotton pad 13 is sufficiently large.Specifically, in the present embodiment, the internal diameter of annular filter cotton pad 13 is preferably adopted than through hole The scope of the little 5～6mm of 121 internal diameter.

This utility model also proposes a kind of oil filter, and with reference to Fig. 2 and Fig. 3, the oil filter includes assembly center Pipe 20 and machine oil filter core 10, certainly, the oil filter also includes assembly shell 30, waits part.The machine oil filter core 10 concrete Structure is with reference to above-described embodiment and Fig. 1 to Fig. 3；Wherein machine oil filter core 10 is nested with assembly central canal 20, assembly central canal 20 The corresponding two annular filter cotton pads 13 through 10 two ends of machine oil filter core in two ends, and filtered cotton pad and 20 interference of assembly central canal Coordinate.As this oil filter employs whole technical schemes of above-mentioned all embodiments, therefore at least there is above-mentioned enforcement All beneficial effects that the technical scheme of example is brought, this is no longer going to repeat them.

Further, internal diameter of the present embodiment preferably using annular filter cotton pad 13 is less than the external diameter of assembly central canal 20 by 3 ～4mm, so that it is guaranteed that annular filter cotton pad 13 is sufficiently large with the interference degree of the periphery wall of assembly central canal 20, and then ensures end cap 12 with the sealing of assembly central canal 20.

This utility model also proposes a kind of electromotor, and the electromotor includes oil filter, the oil filter concrete Structure and scheme reference above-described embodiment, as this electromotor employs whole technical schemes of above-mentioned all embodiments, therefore All beneficial effects that at least there is the technical scheme of above-described embodiment to be brought, this is no longer going to repeat them.

Preferred embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, Every equivalent structure change that under inventive concept of the present utility model, is made using this utility model description and accompanying drawing content Change, or directly/be used in indirectly other related technical fields and be included in scope of patent protection of the present utility model.
