Abstract
The utility model discloses an oil filter for an automobile. The oil filter for the automobile comprises an outer shell. The outer shell comprises a front cover and a rear cover. The front cover and the rear cover are in threaded connection. An oil inlet is formed in the front cover. An oil outlet is formed in the rear cover. A replacing filter element is arranged between the oil inlet and the oil outlet. An annular boss is arranged on the outer surface of the replacing filter element. An annular groove matched with the annular boss is arranged on a connecting portion of the front cover and the rear cover. The top end and the tail end of the replacing filter element are respectively provided with a connector groove. The top end of the inner surface of the front cover and the top end of the inner surface of the rear cover are respectively provided with a threaded boss matched with each connector groove in a threaded mode. The oil filter for the automobile has the advantages that the filter element is long in service life, air permeable degree is high, filtered air inlet flow is increased, air inlet resistance is reduced, the surface is smooth, the oil filter is high in oil resistant and water resistant degree and not prone to deformation, and filtering effect is further improved.
Description
Technical field
The utility model relates to a kind of automobile oil filter, belongs to the auto parts machinery field.
Background technique
Heavy-duty car air-strainer of the prior art, its structure are to be equipped with filtering machine oil at filtering housing intracavity bottom, are spacing above it successively and are provided with Steel net and papery filter core.During work, treat that air filtering is normally first after filtering machine oil and Steel net coarse filtration, enter in the motor through the smart filter side of papery filter core again and work.When heavy-duty car is worked under abominable wild environment, as sleety weather, though enter the sleet globule of filter cleaner inner chamber through coarse filtration, but still have the sleet globule of residual fraction also will filter through papery filter core essence, very easily soak damage filter paper this moment, cause the papery filter core to use and scrap, seriously reduced its working life, increased cost of production.
The model utility content
At the deficiency that prior art exists, technical problem to be solved in the utility model is, a kind of automobile oil filter is provided, and increased the working life of filter core, and increase filtering air inlet flow also reduces intake resistance, has reduced user cost.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of automobile oil filter, and it comprises shell, and shell comprises protecgulum and bonnet, and protecgulum and bonnet are threaded; Described protecgulum is provided with filler opening, and bonnet is provided with oil outlet, is provided with the replacement filter core between filler opening and the oil outlet; The outer surface of described replacement filter core is provided with an annular boss, and protecgulum is provided with the annular groove that cooperates with annular boss with the joint of bonnet; Top and the tail end of described replacement filter core are provided with interface slot, and the internal surface top of preceding interior surface top and bonnet is provided with the screw boss with the interface slot screw-thread fit, is provided with through hole in the screw boss, and through hole UNICOM replaces the inner space of filter core.
Optimize, above-mentioned automobile oil filter, it is replaced filter core and comprises the fluid passage, and S-type being arranged in of fluid passage replaced in the filter core.
Optimize, above-mentioned automobile oil filter is provided with some layers of asbestos filter screen in its fluid passage.
Optimize, above-mentioned automobile oil filter, the two ends up and down of its asbestos filter screen are provided with the nano metal filtering layer.
Optimize, above-mentioned automobile oil filter is provided with rubber seal on its filler opening and the oil outlet.
Filter core long service life of the present utility model, not only have the air permeability height, increase filtering air inlet flow and reduce the advantage of intake resistance, any surface finish, and have oil resistant, a fastness to water height, characteristic such as not yielding, its relatively environmental protection, filtering effect is further enhanced, have remarkable economic efficiency and social benefit, further popularizing application prospect is arranged.
