Description

Iron engine oil filter for automobile

Technical Field

The utility model relates to the field of filters, in particular to an iron engine oil filter for an automobile.

Background

The automobile engine is used for a long time during running at a high speed, and lubrication with engine oil is required. The engine oil is stored in an oil pan in the engine, and is pumped to various moving parts to be lubricated through engine oil mercury for recycling, and in the recycling process, the engine oil can be safely used for a long time only by filtering the engine oil with high density. While filtering engine oil becomes important, a typical oil filter is to replace a new filter following an oil replacement cycle.

At present, an engine oil filter in an engine lubricating system is mainly made of iron in an integrated mode, and the main filtering effect is only a paper filter element in the iron filter.

Detailed Description

In order that the manner in which the above recited features, objects and advantages of the present utility model are obtained, a more particular description of the utility model will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. Based on the examples in the embodiments, those skilled in the art can obtain other examples without making any inventive effort, which fall within the scope of the utility model.

Specific embodiments of the present utility model are described below with reference to the accompanying drawings.

Example 1

As shown in fig. 1-3, the iron engine oil filter for the automobile comprises a rear shell 5, a base 13 is connected to the bottom of the rear shell 5 in a threaded manner, an annular groove 12 is formed in the edge of the bottom surface of the base 13, an annular rubber sealing ring 11 is arranged in the annular groove 12, a tubular paper filter element 6 is arranged in the rear shell 5, a pressure limiting valve 3 is arranged at the top of the paper filter element 6, a spring 1 is arranged between the top of the pressure limiting valve 3 and the top of the rear shell 5, an oil outlet pipe 7 is arranged below the paper filter element 6, the oil outlet pipe 7 penetrates through and is fixedly arranged on the base 13, oil inlet holes 10 are formed in the left side and the right side of the bottom surface of the base 13, a rubber ring 8 covering the oil inlet holes 10 is sleeved on the oil outlet pipe 7, a pressing ring 9 is arranged at the bottom of the paper filter element 6, and the pressing ring 9 is pressed on the rubber ring 8. During filtration, engine oil enters the rear shell 5 through the oil inlet 10 (in the process of flowing into the rear shell 5, the engine oil can jack the rubber ring 8 so that the engine oil can smoothly enter the rear shell 5, and when the engine oil in the rear shell 5 wants to pass through the outside of the oil inlet 10, the engine oil drives the rubber ring 8 to cover the oil inlet 10 so that the engine oil can not flow outwards, so that the engine oil can only flow into the rear shell 5 in a one-way), and after being filtered by the paper filter element 6, the engine oil flowing into the rear shell 5 flows out of the rear shell 5 through the oil outlet pipe 7.

When the paper filter element 6 needs to be replaced, the rear shell 5 is rotated, the base 13 is separated from the rear shell 5, the paper filter element 6 is taken out, and a new paper filter element 6 is replaced, so that the replacement of the filter element can be completed.

The top of the rear housing 5 is provided with a hexagonal prism-shaped protrusion 2. The rear housing 5 can be conveniently separated from the base 13 by driving the hexagonal prism-shaped protrusion 2 to rotate by a wrench.

A filter ring 16 is arranged in the oil inlet 10, the filter ring 16 is in sliding connection with the inner wall of the oil inlet 10, and a filter screen is fixedly arranged in the filter ring 16; the top in the oil inlet 10 is fixedly provided with a first limiting ring 18, and the bottom in the oil inlet 10 is fixedly provided with a second limiting ring 14; the top surface of the filter screen is connected with the lower end of a connecting rod 19 through a first hinge 15, and the upper end of the connecting rod 19 is connected with the bottom of the rubber ring 8 through a second hinge 17. When engine oil enters the rear shell 5 through the oil inlet 10, the rubber ring 8 is pushed upwards, the rubber ring 8 drives the filter ring 16 to move upwards to the top of the oil inlet 10 through the connecting rod 19, when the engine oil passes through the oil inlet 10, the engine oil can be preliminarily filtered by the filter screen in the filter ring 16, when the engine oil does not pass through, the rubber ring 8 moves downwards to cover the oil inlet 10, the rubber ring 8 drives the filter ring 16 to move downwards to the bottom of the oil inlet 10 through the connecting rod 19, and impurities accumulated in the oil inlet 10 are synchronously pushed to the bottom of the oil hole 10 in the downward movement process, so that the impurities can be cleaned conveniently.

The foregoing has shown and described the basic principles, principal features and advantages of the utility model. It will be understood by those skilled in the art that the present utility model is not limited to the above-described embodiments, and that the above-described embodiments and descriptions are only preferred embodiments of the present utility model, and are not intended to limit the utility model, and that various changes and modifications may be made therein without departing from the spirit and scope of the utility model as claimed.
