Durable filter with long service life

Abstract

The invention relates to the field of automobile parts, in particular to a durable filter with a long service life. The durable filter comprises a shell, wherein the shell is of a cylindrical hollow structure, an inner net of the cylindrical hollow structure is fixedly installed in the shell, one end of the inner net penetrates through the shell, and a plurality of first supports are fixedly installed on the inner net in an annular distribution mode. A first rolling shaft is arranged at the end, away from the inner net, of each first support, an inner container is fixedly installed in the shell, a plurality of second supports are fixedly installed on the inner wall of the inner container in an annular distribution mode, the second supports and the first supports are arranged in a staggered and corresponding mode, and a second rolling shaft is arranged at the end, away from the inner container, of each second support. Filter paper made of flexible materials is arranged between the first rolling shafts and the second rolling shafts in a sleeved mode, a through groove is formed in the inner container, the through groove corresponds to one first rolling shaft, and a plurality of rotary discs are arranged in the shell and located on the outer side of the inner container in an annular distribution mode. The filter paper inside the filter can be cleaned while the filter is used, and the filter is suitable for popularization.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a long-life durable filter. Background technique [0002] A filter refers to a device that filters impurities or gases through filter paper. It is mostly used in automobiles and is one of the accessories of the engine. Filters are divided into oil filters, fuel filters and air filters according to their functions. , The use of the filter has greatly improved the efficiency and life of the car engine. [0003] Most of the conventional filters have a cylindrical structure. Generally, the filter paper is folded and fixed in the filter in a circular distribution. When the oil is pumped into the filter, under the action of pressure, the oil flows into the filter. At this time, the filter paper can filter out the impurities in the oil and discharge the clean oil through the inner net. This is the most widely used filter at present, but the service life of this filter is Shorter, new filters...

Problems solved by technology

[0003] Most of the conventional filters have a cylindrical structure. Generally, the filter paper is folded and fixed in the filter in a circular distribution. When the oil is pumped into the filter, under the action of pressure, the oil flows into the filter. At this time, the filter paper can filter out the impurities in the oil and discharge the clean oil through the inner net. This is the most widely used filter at present, but the service life of this filter is Shorter, new filters need to be replaced regularly, which increases the cost of use. At the same time, as the filter is used for a long time, the filtering effect of the filter will also decrease, which brings a lot of trouble to the use of the filter. inconvenient
