Description

Air filter with saw-shaped position

Technical Field

The utility model belongs to the technical field of filters, and particularly relates to an air filter with a saw-shaped position.

Background

For an air filter of an automobile engine, the condition of the air filter is related to the service life of the engine, and if the dirty air filter is used during the running of the automobile, the air intake of the engine is insufficient, fuel oil is not completely combusted, and the phenomena of unstable work, power reduction and oil consumption increase of the engine are caused.

The existing air filter usually uses PU glue sealing cover plate to seal to prevent air leakage, the existing sealing cover plate has no saw-shaped structure, the inner side of a general mounting frame has no inner side clamping position, the outer edge of the sealing cover plate is used for sealing with a placing position, and the outer edge of the sealing cover plate can deform inwards (i.e. towards the inner side clamping position direction) due to vibration (shaking) generated during use, and the sealing can deform to cause poor sealing after long-time use to generate air leakage;

if sealed apron inwards increases thickness, although can prolong the time that sealed apron warp, nevertheless to the inboard position of placing that is equipped with inboard screens of mounting bracket, sealed apron is difficult to install and places in the position, and it is protruding to design a section for this reason and be equipped with a plurality of at sealed apron, form the recess between the arch, the protruding air cleaner who forms saw-shaped position with the recess of a plurality of jointly.

Air leakage means: part or all of the air does not pass through the air inlet and the air outlet of the filter.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention,

referring to fig. 1-3 of the drawings,

the utility model provides an air cleaner that saw form position 12 was glued, includes casing 1, top and bottom on the casing 1 are equipped with air inlet 2 and gas outlet 3 respectively, install sealed apron 4 on the gas outlet 3, be equipped with the protruding 8 of a plurality of on the sealed apron 4, form recess 9 between the protruding 8, the protruding 8 of a plurality of forms saw form position 12 jointly with recess 9, saw form position 12 is arranged and is distributed on sealed apron 4.

The principle of the utility model is as follows:

when the air filter works, after air enters a filter element of the air filter through the air inlet 2 arranged on the shell 1, particles in the air are filtered by the filter element.

Be equipped with the protruding 8 of a plurality of on the sealed apron 4, form recess 9 between the arch 8, the protruding 8 of a plurality of forms saw form position 12 with recess 9 jointly, and saw form position 12 range distribution on sealed apron 4, and sealed apron 4 especially saw form position 12 and mould plastics for PU glue material and form, utilize the good leakproofness of PU glue to prevent gas leakage.

Furthermore, the sealing cover plate 4 is provided with a plurality of first cross beams 10 for fixing the shape of the sealing cover plate 4, the sealing cover plate 4 is made of plastic materials, so that the sealing cover plate is easy to deform to a certain extent, and the plurality of first cross beams 10 can mutually support to stabilize the sealing cover plate 4, so that the sealing cover plate 4 is effectively prevented from deforming.

Further, install on casing 1 and be used for the mounting 5 of joint air inlet 2, because the filter during operation produces easily and rocks, consequently fixed through mounting 5, prevent to rock.

Further, one side on the mounting 5 is equipped with and is used for spacing buckle one 6, the middle-end both sides of mounting 5 are equipped with two 7 of a plurality of buckle, because air cleaner can be used to the car, need install in specific position, consequently be equipped with buckle one 6 and two 7 of buckle, correspond the cooperation with the draw-in groove on the car when installing the filter on the car and fix a position firmly.

Further, be equipped with two 11 crossbeams that are used for preventing 5 deformation of mounting on the mounting 5, through the structure that two 11 mutual supports of crossbeam, can effectively stabilize the filter, prevent that the machine during operation from rocking.

Further, the cover plate 4 is annularly provided with an outwardly protruding sealing protrusion 13 on the outer edge.

As shown in fig. 4-5, the product of this patent can be used in both of two forms, specifically:

1. when the inner side of the mounting bracket 14 has no inner side screens 16:

protruding 13 on the sealed apron 4 with place 15 one sides extrusion seal, when the extrusion, sealed apron 4 can inwards be deformed, protruding 8 this moment can produce reaction force to can increase protruding 13 and place 15 one sides extrusion force of position, protruding 8 has increased the intensity that PU glued, and prevents rocking function of product after the installation.

2. When the mounting bracket 14 is provided with the inner detent 16 on the inner side:

in order to produce better sealing performance, the thickness from the protrusion 13 to the protrusion 8 on the sealing cover plate 4 is slightly larger than the width of the placing position 15, and the groove 9 is formed between the protrusions 8, so when the protrusion 13 and the protrusion 8 on the sealing cover plate 4 are installed in the placing position 15, the protrusion 8 is easily installed in the placing position 15 through deformation, and meanwhile, enough extrusion force can be generated to seal one side of the placing position 15 under the protrusion 13.
