Description
Technical field
The utility model belongs to a kind of automobile-use parts, is specifically related to a kind of air filtering core that is used for motor car engine.
Background technique
During motor car engine work, must guarantee to suck the flow and the dustless cleanliness of cylinder air, just can keep normal working state, existing carrier, tractor, air filtering core main structure on various diesel engine such as engineering truck or the petrol engine air-strainer is: be provided with in the cylindrical shape, outer leaching net (12,9), columnar papery is housed between two filter screens, or fibre cloth, or the filter layer of foaming structure, described papery filter layer is most for being folded into the structure of multilayer, or corrugated structure, cylinder bodily form filter body one end is equipped with hat upper end cap (1), the other end is equipped with supporting tray (8), the air of coming in from suction port is washed into the sidewall of upper end cap, and the shunting flabellum (2) of circumferential distribution on the upper end cap sidewall flows to the filter body bottom, passes filter screen and filter layer again and flows out from air outlet, center (14), some filter core is provided with the multiple filtration layer, so that air is carried out multiple times of filtration.The deficiency of this class filter core is the continuity along with the operating time; airborne dirt can amass the sidewall surfaces that expires filter core very soon; cause the intake resistance increase and influence proper functioning, and in the bigger rugged environment of dust storm, the papery filter core also is easy to be punctured by the grains of sand damaged; influence the air filtering effect; increased oil consumption, and the papery filter layer that is arranged between the inside and outside filter screen can not clean, can only disposablely use; cause air filtering core short working life, loss is bigger.
Summary of the invention
It is simple that the technical problems to be solved in the utility model provides a kind of dismounting, is easy to clean long service life, the motor vehicle air filter core that filtering is effective.
The technological scheme that addresses the above problem is (referring to implementing illustration): the utility model be provided with columnar in, outer leaching net (12,9), in, be provided with filter layer (11 between the outer leaching net, 10), the cylinder center hole is air outlet (14), cylindrical filter body one end is equipped with the hat upper end cap (1) that central opening is communicated with air outlet, described center (14), the other end is provided with pallet (8), in the cylindrical shape, outer leaching net and filter layer (11,10) two ends are connected with pallet (8) with upper end cap (1) respectively, it is characterized in that: outside described pallet (8), be set with the filter core supporting disk (6) of fixedlying connected with pallet, be coated with the sponge filter layer (4) of foaming structure on the filter body outer wall between described upper end cap (1) lower edge and the filter core supporting disk (6), the sponge filter layer is coated with the mesh skeleton (3) that is used for fixing the sponge filter layer.
Further scheme is: described mesh skeleton (3) is the cylindrical structure that connects into by link (13) by around the mesh sheets that coats the sponge filter layer.
Further scheme is to be provided with water-leaking hole (5) on described filter core supporting disk (6) again.
This filter core is contained on the air-flow path of motor car engine air inlet, enter the sponge filter layer (4) of the air elder generation of motor through upper end cap, again in the warp, filter layer (10 between the outer leaching net, 11) enter air outlet, center (14) and enter motor, the dust of carrying secretly in the air will be intercepted equably and is scattered on the outer sponge filter layer like this, can in the filter core of lining portion, not gather and harden, cause the obstruction of air-flow, and the filter core layer of portion in for a long time, can pulling down, the sponge of only pulling down the outside crosses filter core and cleans, can often keep the unimpeded of air draught, compare with existing filter core, can improve 4-5 the working life of the utility model filter core doubly, and improve efficiency of engine, reduce the loss of fuel, reached energy-conservation purpose.And the utility model can be advantageously used in existing motor vehicle air filter core is transformed, need only on the filter body sidewall below the upper end cap, coat one deck sponge filter layer, fixed getting final product again with mesh skeleton and filter core supporting disk, the thickness of sponge filter layer can be adjusted as required.
The further scheme of this example fixedly mesh skeleton of sponge filter layer is to be formed by connecting by mesh sheets, is convenient to dismounting more and cleans.
Further scheme can in time be drained the moisture of sleet sky sponge filter screen suction at the water-leaking hole (5) that filter core supporting disk (6) upward is provided with again.
