Description

A kind of oil filter

Technical field:

The utility model relates to a kind of oil filter, but refers in particular to the oil filter of impurity such as a kind of filtering iron powder.

Background technology:

At present, common oil filter structure, be to be provided with several machine oil ingates in the capping end face outside of oil filter body below, other is the flow export of machine oil in the communication port that central authorities then are provided with a tool retaining thread, be provided with the filter paper core of a Zhe song again in the barrel inboard, be equipped with a wire netting in the body center place in addition, be primarily characterized in that, the exit, below of leaning on of this wire netting is equipped with a ring set, this ring set forms the bent body of stepped Zhe, establish tool ferromagnetism oil strainer axle in order to folder, this filtering element (cartridge) rod can filter out cleaner machine oil with the iron powder sorption in the machine oil.

The above-mentioned oil filter of commonly using of detailed sight is not difficult to realize that it has remained a little weak point in fact, and main cause is summarized as follows:

This kind structure is provided with the ferromagnetic filtering element (cartridge) rod of a tool in addition in the body center place, by this filtering element (cartridge) rod stand be arranged at machine oil flow export must through path on, use the iron powder in the sorption machine oil, yet, the manufacturing of this kind structure need be provided with the filtering element (cartridge) rod in addition, the manufacturing of its filtering element (cartridge) rod and group are established all very, and trouble takes a lot of trouble, improve manufacturing cost relatively, and remaining impurities is adsorbed on the filtering element (cartridge) rod in this machine oil, if when using one section in the future, filtering element (cartridge) rod magnetic force disappears, and the feasible iron powder that originally is adsorbed on the filtering element (cartridge) rod drops and together flowed out by the machine oil flow export, and its filter effect is not good.

Moreover the machine oil flow export of this kind structure makes the machine oil that is flow to by the bottom filter paper core need flow to filtering element (cartridge) rod top owing to be shaped to a protuberantia shape, can make machine oil flow out by flow export, it is gone up very in flowing and has some setbacks, and very likely produces the flow-disturbing phenomenon, and is unsatisfactory in the use.

Summary of the invention:

The purpose of this utility model is to provide a kind of oil filter, and it makes easy to be easy, can filter out impurities, and oil strain is smooth and easy, and is practical.

For achieving the above object, the utility model adopts following technical scheme:

A kind of oil filter, in the oil filter body, establish filtering element (cartridge), wherein, the capping of this body is provided with the ingate and the outlet opening that can supply machine oil to flow to and flow out, and filtering element (cartridge) is provided with a communication port that communicates with the outlet opening of body, and chow ring is established filter screen in this filtering element (cartridge), and carry over the filter paper of filter screen periphery winding Zhe song, be sticked at the crimple place of filter paper magnet unit more than at least one group, magnet unit annular spread be in the crimple place of filter paper periphery, uses absorption and filter impurity in the machine oil.

There is the slightly annular table of projection the communication port inboard that communicates with the outlet opening of body on the filtering element (cartridge).

According to said structure, the relative conventional construction of the utility model has following beneficial effect:

One, machine oil is flow in the filtering element (cartridge) by the machine oil ingate of body capping bottom surface, this magnet unit that is attached at filter paper crimple place can be by ferromagnetism that it had and is adsorbed iron powder in the machine oil, after carrying out the filtration of first road, make machine oil flow in the filtering element (cartridge) again by filter paper, filter order by filter paper carries out the filtration of second road, after multiple filter screen via week in the filter paper carries out the filtration of the 3rd road, last flow out by the communication port of filtering element (cartridge) central interior again, and flow out clean machine oil through the outlet opening of capping central authorities, can filter out impurities really.

Two, this magnet unit is owing to be attached at the crimple place of filter paper periphery, its easy construction, easy fast, reduce manufacturing cost relatively, and magnet unit is placed on the filter paper, even magnetic force disappears, the iron powder in this machine oil still can be subjected to filter paper to filter obstruct, and is unlikely to directly to flow to communication port, can filter the iron powder impurity in the machine oil really, have splendid filter efficacy.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is an enforcement schematic diagram of the present utility model.

The specific embodiment:

Referring to Fig. 1, one axial filtering element (cartridge) 2 is set in the oil filter body 1 of the present utility model, wherein, envelope 11 central authorities of this body 1 bottom offer can be for the outlet opening 111 of machine oil outflow, and on capping, establish the some machine oil of tool ingate 112, and a communication port 21 that is connected with the outlet opening 111 of body 1 is offered in filtering element (cartridge) 2 bottom surfaces, there is the slightly annular table 211 of projection communication port 21 inboards, the impurity that annular table 211 can suitably stop filtering element (cartridge) 2 inner bottom parts to accumulate enters outlet opening 111, so that the machine oil cleanliness factor that flows out is better, all side rings are established a metal system filter screen 22 in the filtering element (cartridge) 2, and carry over filter screen 22 peripheries and be arranged with the filter paper 23 of Zhe song, the ferromagnetic magnet unit 3 of tool more than at least one group has been sticked on the face that folds of filter paper 23, magnet unit 3 can some five equilibriums be evenly distributed in the crimple place around the filter paper 23, and present embodiment is passed the imperial examinations at the provincial level and 12 is divided into example, in fact also can be subdivided into more isodisperse, the difference of visual field of employment and arbitrarily increase and decrease obtain the cleaner of ideal operation performance thus.

When implementing, referring to Fig. 2, make machine oil flow in the filtering element (cartridge) 2 by the machine oil ingate 112 of body 1 capping 11 bottom surfaces, this magnet unit 3 that is attached at filter paper 23 crimple places can be by ferromagnetism that it had and is adsorbed iron powder in the machine oil, after carrying out the filtration of first road, make machine oil flow in the filtering element (cartridge) 2 again by filter paper 23, filter order by filter paper 23 carries out the filtration of second road, after multiple filter screen 22 via week in the filter paper 23 carries out the filtration of the 3rd road, last flow out by the communication port 21 of filtering element (cartridge) 2 central interior again, and flow out clean machine oil through the outlet opening 111 of capping 11 central authorities.

Again, this magnet unit 3 is owing to be attached at the crimple place of filter paper 23 peripheries, its easy construction, easy fast, reduction manufacturing cost, and magnet unit 3 relatively is placed on the filter paper 23, even magnetic force disappears, iron powder in this machine oil still can be subjected to filter paper 23 to filter obstruct, and be unlikely to directly to flow to communication port 21, and can filter the iron powder impurity in the machine oil really, have splendid filter efficacy.
