Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of filter, in particular to an oil filter with spiral spoiler. BACKGROUND

[0002] In modern internal combustion engine systems, the oil filter is a key component to ensure the cleanliness of the engine lubrication system and prolong the service life of the engine. Its performance directly affects the reliability and durability of the whole machine. With the continuous pursuit of energy saving and emission reduction, high efficiency and long oil change cycle in the automobile industry, higher requirements are put forward for the filtering efficiency, pollution capacity and flow resistance of the oil filter.

[0003] Currently, the mainstream oil filter in the industry adopts a paper filter structure to intercept mechanical impurities, carbon particles and metal dust and other pollutants in the oil through a porous medium. However, there are still some deficiencies in the prior art: the oil usually flows radially from the outer wall to the inner wall of the filter core. This flow mode lacks effective guidance and disturbance on the surface of the filter core, which causes impurity particles to more easily accumulate locally on the surface of a certain position. This not only rapidly clogs the pores of the filter paper in this area, greatly increasing the flow resistance, but also causes the other most areas of the filter core away from the inlet to be not effectively utilized, resulting in the dust holding capacity of the entire filter core not being fully utilized, and thus the service life being shortened.

[0004] Therefore, an oil filter with a spiral spoiler is proposed to solve the above problems. SUMMARY

[0005] The purpose of the present application is to provide an oil filter with a spiral spoiler to solve the problems existing in the prior art, increase the flow guide structure inside the filter, and improve the service life of the filter.

A flow guide assembly is arranged between the filter core structure and the outer cover, the spiral spoiler one is rotationally connected on the annular base, the bypass valve is fixedly connected with the annular base through a connecting mechanism, a supporting mechanism is fixedly connected in the outer cover, and a stop mechanism is arranged between the supporting mechanism and the annular base.

[0007] Preferably, the connecting mechanism comprises a cylinder fixedly connected to the bypass valve, a plurality of first connecting rods fixedly connected to the cylinder, and the annular base fixedly connected to the first connecting rods.

[0008] Preferably, the supporting mechanism comprises a plurality of second supporting rods fixedly connected to the outer cover, a plurality of L-shaped plates fixedly connected to the second supporting rods, movable plates rotatably connected to the L-shaped plates, a plurality of bottom plates fixedly connected to the annular base, second connecting rods fixedly connected to the bottom plates, and the second connecting rods in transmission connection with the movable plates.

[0009] Preferably, the second supporting rods are slidably sleeved with annular sleeves, third connecting rods are fixedly connected between the annular base and the annular sleeves, long holes are formed in the movable plates, pins are fixedly connected to the second connecting rods, the pins extend into the long holes, and the pins are movably arranged in the long holes.

[0010] Preferably, the filter core structure comprises first and second fixed plates, a filter cartridge and a filter core fixedly connected between the first and second fixed plates, the filter core located outside the filter cartridge, a first through hole formed in the first fixed plate, the first through hole in communication with the connecting cylinder, a second through hole formed in the second fixed plate, and the bypass valve arranged in the second through hole.

[0011] Preferably, the bypass valve comprises a valve body located in the second through hole, an annular baffle fixedly connected in the filter cartridge, a spring fixedly connected between the annular baffle and the valve body, and the cylinder fixedly connected to the valve body.

[0012] Preferably, the valve body is fixedly connected with an annular mounting plate, a third supporting rod rotatably connected in the annular mounting plate, and a spiral spoiler two fixedly connected to the third supporting rod.

[0013] Preferably, the outer cover is fixedly connected with a plurality of inclined plates and intercepting plates, the inclined plates are fixedly connected to the side walls of the outer cover, and the intercepting plates are located on the bottom wall of the outer cover.

[0014] Preferably, the check valve comprises an elastic rubber plate, a protective ring fixedly connected outside the connecting cylinder, the elastic rubber plate fixedly connected outside the protective ring, and the elastic rubber plate covering the liquid inlet.

[0015] Preferably, a fourth connecting rod is fixedly connected to the third support rod, and an umbrella-shaped filter screen is fixedly connected to the fourth connecting rod, with the umbrella-shaped filter screen located below the drain port.

[0016] This invention discloses the following technical effects: In this device, the connecting cylinder has a threaded opening and is used to connect to the vehicle. Engine oil enters the outer cover through the inlet. The filter element structure is used to filter the engine oil. A spiral baffle is used to turbulent the engine oil flow. When the engine oil enters the outer cover from the inlet, it flows onto the spiral baffle. The spiral baffle is set on the outside of the filter element structure, with the side of the spiral baffle closer to the filter element structure being higher. When the engine oil flows past the spiral baffle, it preferentially flows along the spiral baffle on the outside, preventing the engine oil from concentrating near the drain port. A bypass valve is also included. This device is used to allow oil to pass through. When the oil pressure inside the outer casing is high, the bypass valve opens, allowing the oil to pass through quickly and reducing the oil pressure inside the casing. When the bypass valve opens, it drives the connecting mechanism to move, which in turn drives the stop mechanism to open, allowing the spiral baffle plate to rotate on the annular base. The rotation of the spiral baffle plate agitates the oil inside the outer casing, which helps to flush away dirt on the filter element structure, thereby further improving the filter element's filtration capacity. When the pressure inside the outer casing decreases, the bypass valve closes, the stop mechanism returns to its original position, and the spiral baffle plate stops rotating. This invention can prevent impurities in the oil from accumulating in one location, resulting in more even use of the filtration components and improving the durability of the device. At the same time, it allows the oil to flow along the baffle plate during operation, and large particles generate centrifugal force, thus being thrown against the wall and flowing down the baffle plate to the bottom, reducing the degree of filter element clogging.
