Description

Technical Field

[0001] The utility model relates to the technical field of engine oil filters, in particular to a magnetic attachment engine oil filter. Background Art

[0002] Before engine oil enters the engine, it is necessary to rely on an engine oil filter to filter impurities in the engine oil to effectively protect the engine. There is an existing patent for an engine oil filter with the patent publication number CN212614942U, which includes an inner filter sleeve, a lower filter cover, an upper filter cover, an annular folded filter paper, a triangular limit block, and a rubber sealing gasket. The bottom of the inner filter sleeve is fixedly welded with a lower filter cover, the top of the inner filter sleeve is provided with an upper filter cover, the outer periphery of the inner filter sleeve is sleeved with an annular folded filter paper, the annular folded filter paper is clamped between the lower filter cover and the upper filter cover, the inner bottom of the lower filter cover is fixedly provided with triangular limit blocks corresponding to the inner corner folds of the annular folded filter paper, the top of the inner filter sleeve is provided with a threaded interface, and the inner bottom of the upper filter cover is provided with a threaded sleeve corresponding to the threaded interface. When the overall filtration device is replaced and maintained, personnel only need to replace the annular folded filter paper without replacing the overall filter element, which greatly reduces the production cost, reduces the generation of polluted waste, achieves a good environmental protection effect, and has high practicability.

[0003] Regarding the above related technologies, the inventor believes that there are the following defects: during the actual use of this engine oil filter, when personnel are too late to replace the engine oil filter, too many impurities are intercepted on the surface of the annular folded filter paper inside the engine oil filter, resulting in the engine oil being unable to pass through the engine oil filter into the engine normally, which will cause the engine to run idly, thereby affecting the service life of the engine. That is, the technical solution proposed by the above patent technology has the defect of being unable to give an alarm for replacing the engine oil filter.

[0004] Therefore, we propose a magnetic attachment engine oil filter to solve the above problems. Content of the Utility Model

Embodiment

[0030] Please refer to Figures 1-4 , the present utility model provides a technical solution: a magnetic attachment machine filter, including:

[0031] A housing 100, and a plurality of oil inlets 200 are arranged in a circumferential array at the top of the housing 100, and an oil outlet pipe 300 extending into the housing 100 is embedded in the upper surface of the housing 100;

[0032] The first filtering component 400 includes two first mounting rings 401 fixedly arranged on the outer surface of the oil outlet pipe 300, and a first folded filter paper 402 is fixedly arranged on the opposite surfaces of the two first mounting rings 401. The first filtering component 400 further includes a plurality of first oil outlets 403 evenly arranged in a circumferential array on the inner wall of the oil outlet pipe 300;

[0033] A plurality of magnetic rods 404 for adsorbing metal debris in the engine oil are fixedly arranged at the end of the first folded filter paper 402, so as to prevent the metal debris from entering the interior of the engine through the first folded filter paper 402 and causing damage to the engine.

[0034] The anti-clogging alarm component 500 is used to prevent the first folded filter paper 402 from being clogged and affecting the normal entry of engine oil into the interior of the engine. The anti-clogging alarm component 500 includes a fixing ring 501 fixedly arranged on the inner wall of the housing 100. A plurality of oil holes 502 are arranged in a circumferential array on the upper surface of the fixing ring 501. The anti-clogging alarm component 500 further includes a sliding ring 503 slidably arranged on the inner wall of the housing 100, and a contact alarm 504 fixedly arranged on the inner bottom wall of the housing 100 and corresponding to the sliding ring 503. A sealing ball 505 corresponding to the oil holes 502 is fixedly arranged on the upper surface of the sliding ring 503, and a plurality of springs 506 are fixedly arranged in a circumferential array between the lower surface of the sliding ring 503 and the inner bottom wall of the housing 100;

[0035] A sealing ring 507 is fixedly arranged on the inner ring surface of the fixing ring 501, and the inner ring surface of the sealing ring 507 is slidably connected to the outer surface of the oil outlet pipe 300, which can prevent engine oil from leaking through the gap between the fixing ring 501 and the oil outlet pipe 300.

[0036] In this embodiment, by arranging the first filtering component 400 and the anti-clogging alarm component 500, during the actual use of the engine oil filter, when the impurities intercepted by the first folded filter paper 402 reach a certain amount, at this time, the first folded filter paper 402 will intercept the flow of engine oil, thereby driving the sliding ring 503 to move downward and contacting the contact alarm 504, thereby triggering the contact alarm 504 to give an alarm, reminding the driver to replace and clean the engine oil filter, and thus effectively solving the defect in the prior art that the engine oil filter cannot be replaced and alarmed. Embodiment

[0037] On the basis of Embodiment 1, and different from Embodiment 1,

[0038] A magnetic adsorption engine oil filter further includes:

[0039] A second filtering component 600, which is used to filter the engine oil passing through the oil holes 502.

[0040] The second filtering component 600 includes a filtering cylinder 601 embedded in the inner bottom wall of the oil outlet pipe 300, and a plurality of second oil outlet openings 602 are evenly formed in a circumferential manner on the outer surface of the filtering cylinder 601, facilitating the entry of engine oil into the oil outlet pipe 300.

[0041] The oil outlet pipe 300 has an open top and a sealed bottom structure, and the filtering cylinder 601 has an open bottom and a sealed top structure.

[0042] Two symmetric second mounting rings 603 are fixedly arranged on the outer surface of the filtering cylinder 601, and a second folding filter paper 604 is fixedly arranged on the opposite surfaces of the two second mounting rings 603, capable of effectively filtering the engine oil that can enter the interior of the filtering cylinder 601 through the oil holes 502.

[0043] In this embodiment, by providing the second filtering component 600, impurities in the engine oil can be prevented from entering the engine, achieving effective protection for the engine.

[0044] During operation, in the actual use of this engine oil filter, after the engine oil enters the interior of the housing 100 through the oil inlet 200, it can filter impurities under the action of the first folding filter paper 402, and at the same time, adsorb and intercept metal debris in the engine oil under the action of the magnetic rod 404. Then, the engine oil enters the oil outlet pipe 300 through the first oil outlet 403 and then enters the engine interior, achieving the purpose of fully intercepting impurities and metal debris in the engine oil. At the same time, when the impurities intercepted by the first folding filter paper 402 reach a certain amount, at this time, the first folding filter paper 402 will intercept the flow of the engine oil. At this time, the engine oil can squeeze the oil holes 502 on the fixed ring 501, causing the sealing ball 505 to move downward, thereby driving the sliding ring 503 to move downward, so that the engine oil can enter the oil outlet pipe 300 through the oil holes 502 and enter the engine interior, avoiding the situation of engine idling. Moreover, when the sliding ring 503 moves downward, it can contact the contact alarm 504, thereby triggering the contact alarm 504 to give an alarm, reminding the driver to replace and clean the engine oil filter, effectively solving the defect in the prior art that the engine oil filter cannot be replaced and alarmed. And when the engine oil passes through the oil holes 502, it can enter the filtering cylinder 601, pass through the second oil outlet openings 602 on the filtering cylinder 601, and then be filtered by the second folding filter paper 604 and enter the interior of the engine, thereby preventing impurities in the engine oil from entering the engine and achieving effective protection for the engine.

[0045] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
