Abstract
The invention relates to an engine oil filter. The engine oil filter comprises a housing in which a filter element and a magnet are arranged. The housing is characterized by further comprising a first supporting plate, a second supporting plate and a rough filtering screen; the first supporting plate and the second supporting plate are fixed into the housing and then divide an inner cavity of the housing into an oil inlet cavity, an oil filter cavity and an oil outlet cavity; the magnet is positioned in the oil inlet cavity; a center hole is formed in the magnet; the rough filter screen surrounds the magnet; a through hole which is communicated with the center hole in the magnet is arranged in the first supporting plate; the filter element is positioned in the oil filter cavity, and two ends of the filter element are respectively clung to the first supporting plate and the second supporting plate; a plurality of oil holes are formed in the second supporting plate and surround the filter element. With the adoption of the engine oil filter, metal impurities in the lubricating oil can be absorbed, and thus the filter element can be prevented from being blocked.
Description
Technical field
The present invention relates to a kind of oil filter.
Background technique
Oil filter major part is in the market only by filter element filtering, and oil filter is after using after a while, filter core can be assembled the broken end of many metals, cause filter cleaner to block, and hinders lubrication system normally to work.
For solving the problem, now disclose a kind of oil filter in the art, the filter core comprising housing, base and be arranged in housing, the filter core in described base top, housing has magnet.Described magnet is discoid magnet steel.Because magnet is mounted between base and filter core, operationally, along with the lubricant oil entered in housing increases, major part lubricant oil then to have little time attract by the magnetic force of magnet, just flow to filter core to be filtered, therefore, still have most of impurity to be mixed in lubricant oil.
Summary of the invention
For above-mentioned technical problem, main purpose of the present invention is to provide a kind of oil filter, and the present invention can metal impurities in adsorpting lubrication oil, prevent filter core blocked.
The technological scheme solved the problems of the technologies described above is as follows:
A kind of oil filter, comprise housing, filter core is provided with in housing, magnet, also comprise the first dunnage, second dunnage and thick filtering net, first dunnage and the second dunnage are fixed on after in housing, the inner chamber of housing is divided into oil suction chamber, oil strain chamber and go out oil pocket, described magnet is arranged in oil suction chamber, magnet is provided with center hole, described thick filtering net is looped around around magnet, first dunnage is provided with the through hole be communicated with magnet center hole, described filter core is arranged in oil strain chamber, the two ends of filter core are close to the first dunnage and the second dunnage respectively, second dunnage is provided with multiple oilhole, these oilholes are looped around around filter core.
Described magnet is cone.
Center hole on described magnet is taper hole, and the aperture of the entrance point of this center hole is greater than the aperture of outlet stomidium.
Have employed such scheme, when lubricant oil is from after the oil inlet pipe housing enters into oil suction chamber, first by thick filtering net, lubricant oil is filtered, thick filtering net is while filtering lubricant oil, reduce the flow velocity of lubricant oil, and thick filtering net and magnet close proximity, therefore, lubricant oil is while being filtered, the magnetic force that produces by magnet attract, metal impurities entrained in lubricant oil are adsorbed onto the surface of magnet, the lubricant oil be filtered and adsorbed flow in oil strain chamber through the center hole of magnet and the through hole of the first dunnage, carry out essence by filter core to filter, oil after filtration flows to out in oil pocket by oilhole, discharged by the oil outlet tube on housing.The present invention filters in all directions lubricant oil and adsorbs, and eliminates the metal impurities in lubricant oil, avoids the blocking of filter core.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
1 is housing, and 1a is oil inlet pipe, and 1b is oil outlet tube, and 2 is filter core, and 3 is magnet, hole centered by 3a, and 4 is the first dunnage, and 4a is through hole, and 5 is the second dunnage, and 5a is oilhole, and 6 is thick filtering net.
Embodiment
With reference to Fig. 1, a kind of oil filter of the present invention, comprises housing 1, and the outer wall of housing 1 is provided with and the oil inlet pipe 1a of its inner space and oil outlet tube 1b.Be provided with filter core 2, magnet 3 in housing 1, also comprise the first dunnage 4, second dunnage 5 and thick filtering net 6.First dunnage 4 and the second dunnage 5 are fixed on after in housing 1, the inner chamber of housing 1 are divided into oil suction chamber, oil strain chamber and go out oil pocket.Described magnet 3 is arranged in oil suction chamber, and described magnet is cone.Magnet is provided with center hole 3a, and the center hole on described magnet is taper hole, and the aperture of the entrance point of this center hole is greater than the aperture of outlet stomidium.Described thick filtering net 6 is looped around around magnet, first dunnage 4 is provided with the through hole 4a be communicated with magnet center hole 3a, described filter core 2 is arranged in oil strain chamber, the two ends of filter core 2 are close to the first dunnage 4 and the second dunnage 5 respectively, second dunnage is provided with multiple oilhole 5a, and these oilholes 5a is looped around around filter core.
