Abstract

The utility model discloses the filter element of the air cleaner and comprises an outer filter element, an inner filter element which is positioned inside the outer element. The utility model is characterized in that: the outer filter element comprises two elastic end covers, an inner and an outer screeners and a filter layer. The inner filter element comprises two elastic end covers, an inner and an outer screeners and a filter layer. The screener of the inner filter element is arranged between the outer screener and the inner screener. The two elastic end covers are cast at the two ends of the inner and the outer screener. The cover surface of one if the elastic end cover of the outer filter element is provided with a sealing lug boss, the inner ring surface is provided with plurality layers of sealing grooves, the outer ring surface of the one of the elastic end cover of the outer filter element is provided with plurality layers of sealing lug bosses. The end covers of the utility model adopt elastic material to manufacture and are provided with sealing lug bosses and sealing grooves for better sealing effect and to realize self-sealing of the cleaner. The utility model has wide range of application, low cost and is easy to replace.

Description

The filter core of air-strainer

Technical field

The utility model relates to a kind of filter core, specifically a kind of filter core of air-strainer.

Background technique

In the prior art, the filter core of engine air filter is normally fixedly formed by end cap by in the middle of the two-layer filter screen filter layer being set again, end cap all adopts metal end, and on metal end, paste rubber washer and realize sealing, this kind filter core sealing effect is bad, end cap gets rusty easily, and can influence motor working life and manufacture cost height.

Summary of the invention

The purpose of this utility model is the filter core of a kind of air-strainer of providing at the deficiencies in the prior art, is provided with filter layer in its filter screen, and end cap and filter screen once-cast are fixed, and end cap adopts elastic material to make, good sealing effect, and processing is simple, and cost is low.

The concrete technological scheme that realizes the utility model purpose is: the filter core of air-strainer, comprise outer filter core, inner filter core, inner filter core is contained in the outer filter core, characteristics are that outer filter core is made up of two elasticity end caps, inside and outside filter screen and filter layer, and inner filter core is made up of two elasticity end caps, inside and outside filter screen and filter layer; The filter layer of outer filter core is located between outer leaching net, the Inner filter net, and two elasticity end cap once-casts are fixed on inside and outside filter screen two ends; The filter layer of inner filter core is located between outer leaching net, the Inner filter net, and two elasticity end cap once-casts are fixed on inside and outside filter screen two ends; The capping of outer filter core one elasticity end cap is provided with seal boss, and inner ring surface is provided with several layers of sealed groove; Inner filter core one elasticity end cap outer ring surface is provided with several layers of seal boss.

The utility model end cap adopts elastic material to make, and is provided with seal boss and sealed groove on end cap, and good sealing effect can be realized the sealing of filter cleaner oneself centering, and adaptive temperature is wide, and processing cost is low, changes easily.
