The air filtering body assembly structure of the air filter further comprises an end cap. The upper housing assembly and the lower housing assembly are fixedly connected. The end cap is fixed with the lower housing assembly. The filtering core assembly is provided between the lower housing assembly and the end cap. The air filtering body assembly structure of the air filter according to the utility model satisfies a sealing requirement.

Description

The sky filter body assembly structure of air-strainer

Technical field

The utility model relates to a kind of air-strainer, particularly a kind of sky of air-strainer filter body assembly structure.

Background technique

Air-strainer is the device that a kind of air purifies; It is filtered suction tude, empty filter body assembly structure, sky by sky and leaches tracheae and form; Empty filter body assembly structure comprises upper shell assembly, lower shell body assembly and element kit, and element kit is arranged in the housing with rational structure.Leaching tracheae through sky is connected with engine intake and is used for filtering atmosphere various foreign matters, for example dust, sand grains etc. are arranged.If filter directly entering motor without air-strainer, various foreign matters will speed up the wearing and tearing of motor, thereby reduce the working life of motor.Sometimes tire can take up slungshot, in case get into motor, just can make motor badly damaged.

As shown in Figure 1; The sky filter body assembly structure of existing air-strainer comprises upper shell assembly 3, lower shell body assembly 1 and element kit 2; Lower shell body assembly 1 is used to get into dirty air, and element kit 2 is used to filter dirty air, and upper shell assembly 3 will filter the clean air in back and be incorporated in the motor through steam outlet pipe; Element kit 2 generally is with polyurethane (Polyurethane; PU) material is to two end face material loadings up and down, and seals with upper shell assembly, lower shell body assembly interference 1～1.5mm, and the spatial arrangement of this Placement is to have satisfied not sealing and maximum filtering area requirements.

The model utility content

The utility model technical problem to be solved provides a kind of sky filter body assembly structure of air-strainer, and it satisfies sealing requirements.

For solveing the technical problem; The utility model provides a kind of sky filter body assembly structure of air-strainer, and the sky filter body assembly structure of air-strainer comprises upper shell assembly, lower shell body assembly, element kit, it is characterized in that; The sky filter body assembly structure of air-strainer also comprises end cap; The upper shell assembly is fixedly connected with the lower shell body assembly, and end cap and lower shell body assembly are fixed, and element kit is located between lower shell body assembly and the end cap.

Preferably, said element kit is shaped as cylindrical body.

Preferably, an end of an end of said lower shell body assembly and end cap all has cone angle.

The positive progressive effect of the utility model is: the utility model is in irregular space, and the shape of element kit is designed to cylindrical body from cuboid, has increased effective filtration area like this, has increased dust containing capacity, the sealing surface of the element kit inboard that coexists.

Fig. 2 is the schematic internal view of the sky filter body assembly structure of the utility model air-strainer.

Fig. 3 is the schematic representation of the sky filter body assembly structure of the utility model air-strainer.

Embodiment

Lift a preferred embodiment below, and combine accompanying drawing to come the clearer the utility model of intactly explaining.

As shown in Figures 2 and 3; The sky filter body assembly structure of the utility model air-strainer comprises upper shell assembly 11, lower shell body assembly 12, element kit 13, end cap 14; Upper shell assembly 11 is fixedly connected with lower shell body assembly 12; End cap 14 is fixing through tapping screw and lower shell body assembly 12, and element kit 13 is located between lower shell body assembly 12 and the end cap 14.Element kit 13 be shaped as cylindrical body, like this maximum using irregular space.One end of lower shell body assembly 12 and an end of end cap 14 all have cone angle 15, easily element kit are imported assembling, seal simultaneously.

Lower shell body assembly 12 is used for absorbing natural air from external environment; Element kit 13 is used for filtering from the dirty air of lower shell body assembly 12 entering and with cleaned air to be imported the upper shell assembly 11; Upper shell assembly 11 is used for the clean empty filter after the engine air inlet tube delivery of filtered; 14 pairs of element kits 13 of end cap seal and can not leak, and satisfy sealing requirements.The polyurethane material foaming is used in the upper and lower end face of element kit, and polyurethane material has elasticity, and an end of element kit inserts in the lower shell body assembly earlier and seals, and covers end cap then, and the decrement of polyurethane material is between 0.5～0.8mm here.

Though more than described the embodiment of the utility model; But those skilled in the art is to be understood that; These only illustrate, and under the prerequisite of principle that does not deviate from the utility model and essence, can make numerous variations or modification to these mode of executions.Therefore, the protection domain of the utility model is limited appended claims.

Claims

1. the sky of an air-strainer is filtered the body assembly structure; The sky filter body assembly structure of air-strainer comprises upper shell assembly, lower shell body assembly, element kit; It is characterized in that the sky filter body assembly structure of air-strainer also comprises end cap, the upper shell assembly is fixedly connected with the lower shell body assembly; End cap and lower shell body assembly are fixed, and element kit is located between lower shell body assembly and the end cap.

2. the sky of air-strainer as claimed in claim 1 filter body assembly structure is characterized in that, said element kit be shaped as cylindrical body.

3. the sky of air-strainer as claimed in claim 1 filter body assembly structure is characterized in that an end of said lower shell body assembly and an end of end cap all have cone angle.
