Description

Filter cleaner

The utility model relates to a kind of air filtration unit, and especially relating to a kind of is the air filtration unit that raw material is made with engineering plastics, is mainly used in petrol engine, diesel engine field.

At present, common air-strainer on the market comprises lid, shell, filter screen, filter-core shell, conduit, connects dish and screw rod, and wherein screw rod is welded in the conduit, and screw rod often comes off because of shake, thereby causes great mechanical accident; In addition, because lid, shell, the filter-core shell of air-strainer, to connect dish all be to be made by metallic material, be corroded easily, thereby shortened its operating life, greatly reduce unfailing performance, increased the weight and the production run cost of whole filter, and production technology is also very complicated.

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art and a kind of good reliability, acid resistant alkali, corrosion-resistant, production technology is simple, weight is low, cost is low air filtration unit is provided.

The purpose of this utility model is achieved in that

The utility model by strainer cover, filter housing, filter screen, filter-core shell, conduit, connect the dish and screw rod formed, wherein, filter screen is fixed in the filter core, conduit, filter housing and connect the dish be that once-through is an one, conduit is positioned at position, filter cleaner medial axis, its external diameter size is complementary with the interior hole size of filter-core shell, and screw rod is fixed in the top of conduit and is complementary with strainer cover.

Wherein, strainer cover of the present utility model, filter housing, filter-core shell, conduit, to connect dish all be to be that raw material is made by engineering plastics;

Strainer cover, filter housing, conduit, to connect dish be to be that raw material is made by polyethylene or ABS material or PVC;

Filter-core shell is to be that raw material is made by polypropylene or ABS material or PVC.

The utility model has following advantage than prior art:

Because the utility model is with conduit, filter housing, connecing the dish once-through is one, and screw rod is fixed in the top of conduit, thereby each parts global reliability can be strengthened greatly, thereby avoided producing because of the come off mechanical accident that causes of screw rod, simultaneously, because critical piece of the present utility model all adopts engineering plastics to make, adopt molding and forming, thereby simplified production technology, reduced cost of production 10-15%, made the utility model acid resistant alkali simultaneously, corrosion-resistant, in addition, because engineering plastic surface is more smooth, has reduced intake resistance, thereby has reduced the oil consumption of declared working condition.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is that of the present utility model facing partly cutd open figure.

The utility model by strainer cover 1, filter housing 2, filter screen 3, filter-core shell 4, conduit 5, connect the dish 6 and screw rod 7 formed, wherein, filter screen 3 is fixed in the filter core 4, conduit 5, filter housing 2 and to connect dish 6 be that once-through is an one, conduit 5 is positioned at position, filter cleaner medial axis, its external diameter size is complementary with filter-core shell 4 interior hole sizes, and screw rod 7 is fixed in the top of conduit 5 and is complementary with strainer cover 1.

Strainer cover 1, filter housing 2, conduit 5, to connect dish 6 be to be that raw material is made by polyethylene;

Filter-core shell 4 is to be that raw material is made by polypropylene.
