Abstract
The invention relates to an oil filter, which comprises a shell and a filter core arranged in the shell. The shell is provided with an oil inlet and an oil outlet, and the oil inlet and the oil outlet are respectively provided with a sealing pad. The oil filter is characterized in that the filter core comprises an outer filter core and an inner filter core arranged in the outer filter core, an oil filtration chamber is formed between the inner filter core and the outer filter core, and the oil inlet is communicated with the oil filtration chamber. By adopting the structure, the oil filtration area is greatly increased, the filtration efficiency is improved, and the service life of the oil filter is prolonged.
Description
Technical field
The present invention relates to a kind of auto parts machinery, particularly a kind of oil filter that is used for removing the impurity of automobile engine oil.
Background technique
The filter core of existing oil filter generally is a filter screen, when machine oil is filtered, machine oil is passed in the filter screen, impurity is stayed the bottom surface of filter screen, in filter process, have only the bottom surface of filter screen that machine oil is filtered, filter area is less, the bottom long term of filter screen stops up easily, influences its normal use.
Summary of the invention
It is little to the objective of the invention is to the filter area that exists at the existing oil filter described in the background technique, and blocking problem provides a kind of oil filter that can solve foregoing problems easily.
The technological scheme that realizes goal of the invention of the present invention is as follows:
A kind of oil filter, it comprises housing and is arranged at the interior filter core of housing, housing is provided with oil inlet hole and oil outlet, oil inlet hole and oil outlet place are provided with sealing gasket, described filter core comprises outer filter core and is arranged at the interior internal layer filter core of outer filter core, form the oil strain chamber between internal layer filter core and outer filter core, oil inlet hole is communicated with the oil strain chamber.
The bottom surface in described oil strain chamber is the conical surface, and the heart is provided with the impurity delivery line therein.
Be provided with the machine oil delivery line in the described internal layer filter core.
Beneficial effect of the present invention is for comprising outer filter core and internal layer filter core because of filter core of the present invention, when machine oil is filtered, machine oil enters in the oil strain chamber between internal layer filter core and the outer filter core by oil inlet hole, because the oil strain cavity space is less, machine oil enters back liquid level meeting fast rise, part machine oil enters into the internal layer filter core by filtration, this part machine oil is derived by the machine oil delivery line, another part then arrives the filter core outside by filtering directly by outer filter core, this part machine oil is derived by oil outlet, by this set, strengthened the machine oil filter area, improved the efficient of filtering.After the long-term use of filter cleaner, can there be certain impurity in the oil strain chamber, connects piston in impurity delivery line outlet port, the impurity in the oil strain chamber can be extracted out, make it can continue to use, prolong the working life of oil filter.
Description of drawings
Fig. 1 is a schematic representation of the present invention;
Among the figure, 1 is housing, and 2 is oil inlet hole, and 3 is oil outlet, and 4 is sealing gasket, and 5 is outer filter core, and 6 is the internal layer filter core, and 7 is the oil strain chamber, and 8 is the impurity delivery line, and 9 is the machine oil delivery line.
Embodiment
With reference to a kind of oil filter shown in Figure 1, it comprises housing 1 and the filter core that is arranged in the housing 1, housing 1 is provided with oil inlet hole 2 and oil outlet 3, oil inlet hole 2 and oil outlet 3 places are provided with sealing gasket 4, described filter core comprises outer filter core 5 and the internal layer filter core 6 that is arranged in the outer filter core 5, form oil strain chamber 7 between internal layer filter core 6 and outer filter core 5, oil inlet hole 2 is communicated with oil strain chamber 7; The bottom surface in described oil strain chamber 7 is the conical surface, and the heart is provided with impurity delivery line 8 therein; Be provided with machine oil delivery line 9 in the described internal layer filter core 6.Because filter core of the present invention comprises outer filter core 5 and internal layer filter core 6, when machine oil is filtered, machine oil enters in the oil strain chamber 7 between internal layer filter core 6 and the outer filter core 5 by oil inlet hole 2, because 7 spaces, oil strain chamber are less, machine oil enters back liquid level meeting fast rise, part machine oil enters into internal layer filter core 6 by filtration, this part machine oil is derived by machine oil delivery line 9, another part then arrives the filter core outside by filtering directly by outer filter core 5, this part machine oil is derived by oil outlet 3, by this set, strengthened the machine oil filter area, improved the efficient of filtering.After the long-term use of filter cleaner, can there be certain impurity in the oil strain chamber 7, connects piston in impurity delivery line 8 outlet ports, the impurity in the oil strain chamber 7 can be extracted out, make it can continue use, prolong the working life of oil filter.
