Problems solved by technology

[0002] Existing oil filters rely on a single paper filter element to intercept and filter out harmful impurities in the oil. The smaller the pores of the filter paper, the better the filtering effect, but the poorer the oil passing capacity.

Embodiment Construction

[0021] refer to figure 1 , figure 2 , the present invention proposes an anti-clogging type oil filter, comprising a housing 1, a bottom plate 2, a first filter mechanism, and a second filter mechanism, wherein:

[0022] The casing 1 is a cylindrical structure with one end open. The inner cavity of the casing 1 is provided with a partition 3, which divides the inner cavity of the casing 1 into a first chamber and a second chamber. The partition 3 is provided with a first oil guide Hole 4 and the second oil guide hole 5.

[0023] The bottom plate 2 is mated with the open end of the shell 1 to seal the shell 1 , and the bottom plate 2 is provided with an oil inlet 6 and an oil outlet 7 .

[0024] The first filter mechanism is arranged in the first chamber. The first filter mechanism includes a first magnetic adsorption device and a first filter element. The first magnetic adsorption device includes a first cylinder 8 and a plurality of adsorption assemblies. The two ends of th...

Abstract

The invention provides an anti-blockage oil filter. The anti-blockage oil filter comprises a shell, a bottom plate, a first filtering mechanism and a second filtering mechanism. A partition board divides an inner cavity of the shell into a first chamber and a second chamber. The first filtering mechanism is arranged in the first chamber. The first filtering mechanism comprises a first magnetic adsorption device and a first filter element. The second filtering mechanism is arranged in the second chamber. The second filtering mechanism comprises a second magnetic adsorption device and a second filter element. The anti-blockage oil filter adsorbs and filters out different sizes of metal impurities in engine oil through the first magnetic adsorption device and the second magnetic adsorption device so as to reduce the filter pressure of the first filter element and the second filter element, prolong the service cycle of the first filter element and the second filter element and improve the filtering effect of the first filter element and the second filter element. Metal impurities adsorbed by the first magnetic adsorption device can completely stay in a first filtering chamber. Metal impurities adsorbed by the second magnetic adsorption device can be adsorbed onto a second barrel and cannot go into a fourth filtering chamber and a second filtering chamber.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to an anti-clogging type oil filter. Background technique [0002] Existing oil filters rely on a single paper filter core hole to intercept and filter out harmful impurities in the oil. The smaller the micropores of the filter paper, the better the filtering effect, but the poorer the oil passing capacity. In order to solve the contradiction that the smallest particles of impurities can be filtered out on the same filter paper micropores, and a sufficient amount of engine oil can also pass through the micropores. According to the filter branch of the National Internal Combustion Engine Industry Association, the best oil filter on the market can only be designed to filter out 60% of impurities in the oil, which is the maximum filtration value obtained after thousands of experiments. In actual use, there are still 40% of harmful impurities that cannot be effectively filtered out by ...
