Abstract

The utility model belongs to the class of mechanical engineering. The utility model particularly an open self dust removing air filter for an internal combustion engine. The filter comprises an upper cover, filter medium and an air outlet pipe. The utility model is characterized in that the periphery of parallel and corrugated filter medium is stuck and fixed with a main frame; one surface of the filter medium is fixed with a supporting net whose shape is the same as the shape of the filter medium; the main frame is fixedly connected with the upper cover on which the air outlet pipe is fixed; a U-shaped rectifying cover is connected with the upper cover; the filter medium is covered in the U-shaped rectifying cover. The utility model has simple structure. The utility model does not need to be maintained and serviced regularly.

Description

The internal-combustion engine open type is from the dust-collecting air filter cleaner

The utility model belongs to mechanical engineering, particularly relate to a kind of internal-combustion engine with open type from the dust-collecting air filter cleaner.

At present, the employed air-strainer of internal-combustion engine is broadly divided into two kinds, and a kind of is oil bath type, another kind is a dry type, no matter any filter cleaner, in use, must use pretty troublesome stipulating the artificial dust that cleans or clean in the filter core of domestic demand between fare register.

The purpose of this utility model provides a kind of non-maintaining open type from the dust-collecting air filter cleaner.

The technical solution of the utility model is: a kind of internal-combustion engine open type is from the dust-collecting air filter cleaner, comprise cover, filter material, steam outlet pipe, it is characterized in that parallel undulatory filter material four limits and main framing are adhesively fixed together, the filter material inner face be fixed with support mesh, a main framing identical with the filter material shape fixedly connected with last cover, on cover and be fixed with steam outlet pipe, there is a U type cowling to link to each other with last cover, and with the filter material cover within it; Evenly have the oblong aperture that is parallel to each other on the main framing, each oblong aperture two opposite side is turned up the flanging identical with the filter material cross section downwards.

The utlity model has does not need maintaining, simple in structure, advantage such as using effect is good.

Embodiment of the present utility model is described with reference to the accompanying drawings.

Accompanying drawing 1 is the utility model structural representation.

Accompanying drawing 2 is the utility model main framing plan view.

Accompanying drawing 3 is the utility model main framing plan view.

As Figure 1-3, be fixedly connected with a steam outlet pipe 6 on the cover 7 on the rectangular, one U type cowling 1 is arranged, link to each other with last cover 7 with main framing 5, between last cover 7 and cowling 1, a parallel undulatory filter material 2 is arranged, by being adhesively fixed on the main framing 5, filter material 2 inner faces are fixed with the support mesh 3 identical with the filter material shape that play supporting role, evenly have the oblong aperture 9 that is parallel to each other on the main framing 5,9 liang of opposite side of each oblong aperture are turned up 90 ° flanging 8 downwards, the shape of flanging 8 is identical with the cross section of filter material 2 each ripple, the corrugated projection of filter material 2 is placed in the oblong aperture 9, and its end face is fixed into one by bonding with flanging 8, and the both sides in addition of filter material also are bonded on the main framing 5, filter material 2 just connects into one with main framing 5 like this, on cover 7 and main framing 5 between a sealing gasket 4 is arranged.This air-strainer is installed in the bonnet and automobile engine cover fuses or be installed in the operator cabin top fuses with lid of cab, when automobile running, swiftly flowing air is entered by cowling 1 front opening, through cowling 1 rectification,, flow out by open rearward end by filter material 2 outer surfaces, airborne dust does not change direction, directly taken away by high velocity air, the air after filter material 2 filters is sent into internal-combustion engine by steam outlet pipe 6, so this air-strainer need not periodic maintenance.The filter material of this filter can also can be made plane according to the mounting point difference of air filter.

Claims

1. an internal-combustion engine open type is from the dust-collecting air filter cleaner, comprise cover, filter material, steam outlet pipe, it is characterized in that parallel undulatory filter material (2) is adhesively fixed together with main framing (5) all around, the one side of filter material (2) is fixed with the support mesh (3) identical with filter material (2) shape, main framing (5) is fixedlyed connected with last cover (7), be fixed with steam outlet pipe (6) on the last cover (7), have a U type cowling (1) to link to each other with last cover (7), and with filter material (2) cover within it.

2. internal-combustion engine open type according to claim 1 is characterized in that evenly having on the main framing (5) oblong aperture (9) that is parallel to each other from the dust-collecting air filter cleaner, and each oblong aperture (9) two opposite side is turned up the flanging (8) identical with filter material (2) cross section downwards.
