Abstract

The utility model relates to an oil filter shell which intents to reach the aims of effective oil leaking preventing, service life prolonging and production cost reducing. The utility model comprises a body and a cover lid with an integral structure, the body and the cover lid are formed by a plurality times of punching realized by a plurality groups of dies in production, as well as an oil input pipe and an oil output pipe which are integrally connected with a canister body and a tray surface. The utility model enables the production cost of needless previous disposal and weld to be reduced due to the integral structure design, and the oil leaking phenomena can be avoided and a better practical function of leak proofing can be realized due to the reduction of weld places as a result of the integral connections between the oil output pipe, the body of the canister body and the cover lid tray surface.

Description

A kind of oil purifier shell

Technical field

The utility model relates to a kind of oil purifier shell, especially a kind of more economic, practical and durable oil purifier shell that is used for the automobile oil filtering system.

Background technique

Oil purifier provides one filtrating equipment before the car engine fuel oil, before fuel oil enters engine, can will be impregnated in contaminant filter in the fuel oil by oil purifier, make the fuel oil that enters engine more pure, make burning more complete, increase the power of engine, also can reduce environmental pollution, more can guarantee engine life simultaneously.Oil purifier mainly is to be coated with filter core in a shell, and when using in depot, shell and filter core are that one is changed, and be therefore full except the filter core life time, otherwise can not need change.

Yet tradition coats the oil purifier shell B of filter core, shown in Fig. 4,5, mainly comprise a body 40 and capping 50, wherein body 40 comprises a stack shell 41 and oil inlet pipe 42, stack shell 41 1 ends are opening portion 411, and the other end is then for being the closed end 412 of closed shape, and inside has a holding area 413 that is installed with filter core 60, closed end 412 centers are provided with a through hole 414, can be affixed with an oil inlet pipe 42 welding.This capping 50 is made up of card 51 and oil outlet tube 52 that a center has through hole 511, oil outlet tube 52 sets firmly with the through hole 511 of welding manner and card 51, but card 51 involutions of capping 50 are at the opening portion 411 of body 40, make filter core 60 can be located in inside, during use body 40 oil inlet pipes 42 are connected in the fuel tank oil circuit, capping 50 oil outlet tubes 52 are connected in the engine oil circuit, make the fuel oil energy that passes through reach the purpose of impurity screening by filter core 60.But, shown in Fig. 4,5, fuel oil is via oil inlet pipe 42 and oil outlet tube 52 turnover oil purifier shell B, because oil inlet pipe 42 is to fix with welding manner with stack shell 41 and oil outlet tube 52 with card 51, so regular meeting causes the oil impregnate phenomenon, even therefore filter core 60 life time do not arrive, also change oil purifier because of shell B oil impregnate phenomenon is essential, cause meaningless waste; In addition, the manufacturing of tradition oil purifier shell B, wherein into and out of the essential extra welding step that increases between

oil pipe

42,52 and stack shell 41, the card 51, in order to weld processing such as then must carrying out pickling to above-mentioned member earlier, so all, also all cause the significantly raising of cost of production, and the pollution of environment.

Supervise in this, the design people is according to being engaged in the experience that auto parts are manufactured for many years, be to sprout the shortcoming of thinking to improve known oil purifier shell, and effectively reduce its cost of production and increase working life, better quality products at good values can supply to select for use to allow the Consumer have more, through repeatedly test use, and develop the utility model.

Summary of the invention

The utility model is that a kind of oil purifier shell will be provided, its purpose promptly is: provide a kind of and can effectively prevent oil impregnate, the oil purifier shell that increases the service life and can significantly reduce production costs, mat improvement of the present utility model, reach the user cost that reduces the Consumer, and can effectively save to manufacture and requiredly spend the expensive time.

The utility model provides a kind of oil purifier shell, formed by a body and a capping, this body comprises a stack shell and an oil inlet pipe, this capping comprises a card and an oil outlet tube, wherein body stack shell inside have one can be for being installed with the holding area of filter core, oil inlet pipe one end is an opening portion relatively, the capping card can be sealed with the driving fit of body stack shell opening portion, it is characterized in that: body that this body and capping are one of the forming and capping, the stack shell of this body and the card of this capping, oil inlet pipe and oil outlet tube are oil inlet pipe and the oil outlet tube that repeatedly drawing links to each other with stack shell and card one.

The utlity model has following advantage and effect:

1, body, stack shell and oil inlet pipe and capping card and oil outlet tube, be through the array mould integrally formed structural design of punching press repeatedly when producing, do not need the first pickling processes in the traditional product production process, processes such as welding, can effectively reduce production costs, and because of having reduced the operation of pickling processes, thereby reduced environmental pollution indirectly.

2, the utility model is because of into and out of oil pipe being direct and body stack shell, and capping card one links to each other and forms, and does not have soldering point, can effectively avoid the generation of oil impregnate phenomenon, has better leakproof practical effect.
