Abstract

The utility model relates to an engine filtering core belonging to one of accessories of an internal combustion engine and comprising a filter. The filter is a liquid spraying filtering core. Therefore, the utility model with structure not only has high filtering effect, large flow, and good corrosion resistance performance, but also has very simple structure.

Description

A kind of motor filter core

Technical field

The utility model relates to the annex of explosive motor, particularly a kind of motor filter core.

Background technique

Fuel oil (comprising gasoline and diesel oil) that explosive motor is sucked when work and air all must be through filterings, the lubricant oil of circulating lubrication also must be through filtering in motor, therefore, the annex of motor comprises three kinds of vitals: fuel filter, air-strainer and oil filter.The filter paper that adopts cotton yarn, wood fiber, cellulose ester and staple fiber etc. to make is arranged before the filter core of above-mentioned three kinds of filter cleaners, and the filtering efficiency of this structure is low, perishable, the resistance to compression resistance to shock is poor, working life short; Now the filter core that generally uses is to contain the hollow wavy cylinder shape that the plastics of microcellular structure are made, though some shortcomings before having overcome, not only filtering efficiency is low, flow is little, perishable, and complex structure.

The utility model content

The utility model is intended to overcome above-mentioned the deficiencies in the prior art, provides a kind of not only filtering efficiency height, flow big, corrosion-resistant, and motor filter core simple in structure.

According to a kind of motor filter core that the utility model provides, comprise a filter body, described filter body is molten blown filter.

The utility model also has following additional technical feature:

Described filter body is a hollow cylinder, and the both sides up and down of described filter body are respectively equipped with a loam cake and a lower cover.

Described filter body is flat body in many ways, and the top edge of described filter body perisporium is provided with the seal ring of sealing.

The perisporium of described filter body is injected with the fixing belt of sealing.

The upper and lower surface of described filter body is pasted on the internal surface of described loam cake and lower cover respectively.

The inside and outside edge of described loam cake and lower cover all is bent with chimb to the inside.

According to a kind of motor filter core that the utility model provides, prior art has following advantage relatively:

The utility model comprises a filter body, and described filter body is molten spray PP filter core.Therefore, this structure not only filtering efficiency height, flow is big, corrosion-resistant, and structure is also very simple.

Description of drawings

Embodiment below in conjunction with accompanying drawing provides describes the utility model in detail, wherein:

Fig. 1 is the structural representation of a kind of motor of the utility model with a kind of preferred embodiment of filter core;

Fig. 2 is the plan structure schematic representation of Fig. 1;

Fig. 3 be among Fig. 2 A-A to sectional view;

Fig. 4 is the structural representation of the another kind of motor of the utility model with a kind of preferred embodiment of filter core;

Fig. 5 be among Fig. 4 B-B to sectional view.

Embodiment

Referring to Fig. 1 to Fig. 5, a kind of optimal way of two kinds of motors of the utility model with filter core is shown, comprise a filter body 1, described filter body 1 is molten blown filter.Therefore, this structure not only filtering efficiency height, flow is big, corrosion-resistant, and structure is also very simple.Described molten blown filter 3 by polypropylene material through high-temperature fusion, be injected into cellosilk to special machine for forming filter element and the continous way filter core that forms, use controlled different filtering precisions, the surface-type filter core of precision unanimity or the interior tight outer rare degree of depth type filter core etc. inside and outside also can forming made of different production technologies.This filter core itself does not use any chemical adhesion Ji, more meets the high-quality requirement of health, safety.

Referring to Fig. 1 to Fig. 3, the wherein a kind of optimal way of two kinds of motors of the utility model with filter core is shown, described filter body 1 is a hollow cylinder, and the both sides up and down of described filter body are respectively equipped with a loam cake 2 and a lower cover 3; The upper and lower surface of described filter body 1 is pasted on the internal surface of described loam cake 1 and lower cover 2 respectively; The inside and outside edge of described loam cake 1 and lower cover 2 all is bent with chimb 6 to the inside.Described chimb 6 can make that filter body 1 is fixed between loam cake 1 and lower cover more firm.

The upper and lower surface of above-mentioned filter body 1 is its one side of corresponding described loam cake 1 and lower cover 2 respectively, and the inboard of described loam cake 1 and lower cover 2 is respectively described loam cake 1 towards lower direction, lower cover 2 direction up.

Referring to Fig. 4 and Fig. 5, the another kind of optimal way of the utility model is shown, described filter body 1 is flat body in many ways, this polyhedral is cuboid, square body or difformity such as trapezoidal; The top edge of described filter body 1 perisporium is provided with the seal ring 4 of sealing; The perisporium of described filter body 1 is injected with the fixing belt 5 of sealing.Described seal ring 4 seals, and enters described filter body 1 fuel oil, air and machine oil before with prevention and overflows from the top edge of filtering body 1.

The foregoing description is only for the usefulness that the utility model is described; and be not to be to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from spirit and scope of the present utility model; can also make various variations and modification; therefore all technological schemes that are equal to also should belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
