Abstract

The utility model relates to a filter, in particular to an oil filter, which comprises a casing and a filter element, wherein the filter element disposed inside the casing consists of a cylindrical iron core with holes and a piece of filter paper, and the folded filter paper is wound around the iron core. The oil filter is characterized in that two ends of the filter paper are seamed and connected through threads to form a cylindrical filter paper adhered on the iron core. By employing the structure that the joint portion of the filter paper is seamed and fixed by adopting the threads, the filter paper can not crack after becoming soft owing to a long period soak, thereby ensuring tightness of the filter element and having relatively simple structure.

Description

A kind of oil filter

Technical field

The utility model relates to a kind of cleaner, especially a kind of oil filter.

Background technology

The main effect of engine motor oil is farthest to reduce friction, reduction energy loss and the parts depreciation that each parts produces in running.Oil filter plays the effect that purifies machine oil; can remove the impurity such as dust, metallic particles, carbon precipitates and coal soot in the machine oil; assurance machine oil is brought into play lubrication under the free from admixture situation; collect the metal fillings (producing) in the lubricating oil mainly due to the mutual friction of part phase; and the greasy filth that produces because of oxidation of lubricating oil itself, colloid etc., the protection engine.

Filter core is the parts of most critical in the oil filter, paper filter element in the market, comprise filter paper, tubular iron core with holes, behind the folded filter paper on the surface of tubular iron core, with glue or iron plate that the two ends of filter paper are fixedly connected then, the two ends of tubular iron core also are provided with the capping that changes the outfit respectively, and the capping that changes the outfit is fixedlyed connected with filter paper, but because the filter paper long period of soaking is in machine oil, when connecting the filter paper joint, come off easily with glue, and the words that connect with iron plate, filter paper soaks the back deliquescing, easily with the sealing of iron plate separation failure filter paper, part machine oil does not enter in the engine through filtration, can damage engine.

Summary of the invention

The purpose of this utility model is, a kind of oil filter of simple in structure, good airproof performance is provided.

The utility model is to realize by following scheme: a kind of oil filter, comprise housing and filter core, filter core is arranged in the housing, described filter core comprises tubular iron core and filter paper with holes, be wrapped on the iron core behind the folded filter paper, connection is sewed up by fine rule in the two ends that it is characterized in that filter paper, constitutes tubular filter paper and is fitted on the iron core.

This is provided with and adopts the fine rule stitching fixing the joint portion of filter paper, and such structure even filter paper deliquescing after long period of soaking slot can not occur yet, guaranteed the sealing of filter core, and structure is very simple.

Of the present utility modelly further be set to: be equipped with papery annular seal lid at the two ends of tubular filter paper, the two-port fixed seal connection of seal cover and iron core, be tightly connected between the two-port of seal cover and tubular filter paper, the outer surface of iron core and the burst of filter paper constitute a seal chamber.

This two-port that is arranged on filter paper is provided with the papery seal cover respectively, because the material of seal cover and the material of filter paper are the same, so sealing can be better, also can adopt the seal cover of other material, such as metal, plastics etc.

Description of drawings

Fig. 1 is the structural representation of present embodiment;

Fig. 2 is the outside drawing of the housing of present embodiment;

The specific embodiment

With reference to figure 1 as can be known, a kind of oil filter of the utility model, comprise housing 1 and filter core 2, filter core 2 is arranged in the housing 1, filter core 2 comprises tubular iron core 21 with holes and filter paper 22, after folding, filter paper 22 is wrapped on the iron core 21, the two ends of filter paper 22 are sewed up by fine rule 3 and are connected, constituting tubular filter paper 22 is fitted on the iron core 21, be equipped with papery annular seal lid 4 at the two ends of tubular filter paper 22, the two-port fixed seal connection of seal cover 4 and iron core 21 is tightly connected between the two-port of seal cover 4 and tubular filter paper 22, and the burst of the outer surface of iron core 21 and filter paper 22 constitutes a seal chamber.

In the utility model, the seal cover of the material that can adopt other of seal cover such as metal, plastics etc., and adopts papery in the present embodiment, and this is because the sealing that the seal cover of papery is connected with filter paper is fine.

Claims
