Abstract

The utility model discloses an upper end cover sealing device of a safe filter core of an air filter, which comprises a safe filter core sealing ring, an upper end cover, an inner protective pipe, filter materials, an outer protective pipe and a lower end cover, wherein the inner side of the safe filter core sealing ring is provided with a circumferential groove, the upper end cover can be tightly embedded in the circumferential groove, the upper end cover is fixed with the inner protective pipe and the outer protective pipe, the lower end cover is fixed with the inner protective pipe and the outer protective pipe, and the filter materials are arranged between the inner protective pipe and the outer protective pipe. The utility model has the advantages of simple process and low production cost, and is easy to implement and use. Besides, the upper end cover is embedded in the sealing ring so as to form the both into a whole body, thereby effectively avoiding the influence caused by aging and deformation of rubber and overcoming the defects of inaccurate and unstable pasting of the gummed sealing ring. Therefore, the utility model can be widely used for various upper end cover sealing systems of safe filter cores of filters.

Description

Air-strainer safety filter core upper end cap seal arrangement

Technical field

This use is novel to relate to a kind of air-strainer safety filter core upper end cap seal arrangement.

Background technique

Air-strainer is arranged in engine aspirating system, is contained in the place ahead of Carburetor or suction tude, the assembly that it is made up of the filter component of one or several clean air.It mainly acts on is that filtering will enter objectionable impurities in the air of cylinder, to reduce the premature wear of cylinder, piston, piston ring, valve and valve seat.

Kernel component in the air-strainer is an air filtering core, and air filtering core partly is made up of upper and lower end cap, filter material and rubber seal etc.Filter material mainly is two kinds of filter paper and nonwovens, and independent General Purpose Rubber seal ring and end cap are bonded in one, guarantees the sealing of filter core product.The air cleaner cartridge end bracket enclosed is that the body surface that utilizes the elasticity of the plane of rubber seal or flange to be in contact with it produces contact pressure and reaches seal action, prevents that dust and moisture from entering motor by air-strainer.So it is very high that the sealability of safe filter core upper end cap seal arrangement requires.

Existing air-strainer safety filter core upper end cap seal arrangement adopts technique for sticking, the using method complexity, and difficulty is bigger, the cost height, and also rubber is easily aging, easily in the distortion of bonding position, influences the sealability of seal ring.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of air-strainer safety filter core upper end cap seal arrangement is provided.

Air-strainer safety filter core upper end cap seal arrangement comprises safe filter core seal ring, upper end cap, inner protective tube, filter material, outer pillar, lower end cap; There is peripheral groove safe filter core seal ring inboard, and with upper end cap embedding mutually, upper end cap and inner protective tube, outer pillar is fixed, lower end cap and inner protective tube, and outer pillar is fixed, and filter material is attached between inner protective tube and the outer pillar.

Not only technology is simple, cost of production is low for the utility model, easy to implement and application, and upper end cap and seal ring embedding mutually, be equivalent to an integral body, can effectively prevent the influence that the ageing of rubber distortion brings, and solved inaccurate, the not firm defective of gluing seal ring stickup.

Description of drawings

Fig. 1 is an air-strainer safety filter core upper end cap seal arrangement schematic representation;

Fig. 2 is an air-strainer safety filter core upper end cap seal arrangement generalized section;

Among the figure, safe filter core seal ring 1, upper end cap 2, inner protective tube 3, filter material 4, outer pillar 5, lower end cap 6.

Embodiment

As Fig. 1, shown in Figure 2, air-strainer safety filter core upper end cap seal arrangement comprises safe filter core seal ring 1, upper end cap 2, inner protective tube 3, filter material 4, outer pillar 5 and lower end cap 6; There is peripheral groove safe filter core seal ring 1 inboard, with upper end cap 2 embedding mutually, and upper end cap 2 and inner protective tube 3, outer pillar 5 is fixed, lower end cap 6 and inner protective tube 3, outer pillar is fixed, and filter material 4 is attached between inner protective tube 3 and the outer pillar 5.

After filtering again through the filter material 4 of safe filter core by the gas of main filter element filtering, enter suction tude from upper end cap 2.Because the utility model has adopted upper end cap and the seal ring mode of embedding mutually, not only can effectively prevent gas leak phenomenon, play seal action, can also prevent that seal ring from pasting inaccurate not firm or long-term ageing distortion and causing the phenomenon of leaking gas, it is simple to add technology, become the product cost low, so can be widely used in various filter cleaner safety filter core upper end cap sealing systems.
