The use method (working principle) of the invention is as follows:

when the engine oil cooling device works, firstly, engine oil discharged from the interior of an engine is conveyed into an inner cavity of a shell 1 from an oil inlet 3, so that a check valve is opened, then, along with continuous input of the engine oil, the engine oil penetrates through a filter element 5 and a first through hole, and then is discharged into a cooler (in the prior art) from an oil outlet 4, so that the filtered engine oil is cooled, then, the cooled engine oil is conveyed into the engine again by an oil pump (in the prior art), so that continuous lubrication of the engine is realized, afterwards, when the filter element 5 is excessively blocked by impurities in the engine oil, subsequent engine oil can pass through a third through hole, so that a check block in the bypass valve is pushed to move upwards, an elastic piece is extruded, and then the engine oil is directly discharged into the cooler through a second through hole and the oil outlet 4, and in the process, the upward-moving check block drives a driving rod 9 and a driven rod 8 to move upwards synchronously, then the push-pull member 7 is made to press the liquid medium in the upper cavity upwards, so that the liquid enters the liquid cavity through the liquid guide hole 12, and the deflection member 11 is pushed to rotate clockwise, so that the poking member 14 rotates synchronously therewith, and the convex edge of the filter element 5 is poked through the plate body, at this time, the blocking member 13 is fixed, and further the plate body of the poking member 14 and the blocking member at the next position in the rotating direction clamp the convex edge of the filter element 5 together, so that the convex edges between the two are attached to each other tightly, meanwhile, the rotating deflection member 11 extrudes the gas in the gas cavity, so that the gas enters the extension cavity 16 through the communication hole 15, and further the extension member 17 is made to expand longitudinally, so that the convex edges are attached better, the probability of the engine oil carrying impurities away from the surface of the filter element 5 is reduced, finally, after the engine oil stops being input into the shell 1, and further the elastic member releases the elastic force, the stop block moves downwards, so that the structure is reset, and the work cycle is realized.

Example two

Different from the first embodiment, please refer to fig. 1 and fig. 6, the extending end of the extending member 17 is disposed in an inclined manner, the inclined direction is opposite to the rotating direction of the shifting member 14, and through the above arrangement, in the process that the shifting member 14 and the blocking member 13 clamp the convex edge of the filter element 5, the extending member 17 pushes the convex edge, so that the adjacent convex edges are further attached tightly, and the probability that the machine oil is carried away from the impurities on the surface of the filter element 5 is reduced.

In the process of clamping the convex ridges of the filter element 5 by the toggle element 14 and the blocking element 13, the outermost surfaces of the convex ridges, which are tightly adhered to each other, at adjacent positions are greatly opened, so that the included angle formed by the side surfaces is increased, and the filter element 5 at the included angle position still can effectively filter engine oil (because the included angle is smaller in an initial state, and the filter element 5 at the position cannot effectively filter impurities, the probability of blocking the impurities at the position is lower, and then, when the included angle is increased, the filter element 5 at the position can fully contact the engine oil, so that the functions are realized), through the actions, the pressure of the engine oil in the casing 1 is reduced (because the distance from the circumferential wall body at the upper side position of the mounting seat 2 to the circumferential inner wall of the casing 1 is greater than the distance from the circumferential wall body at the lower side position of the mounting seat 2 to the circumferential inner wall of the casing 1, and further, when the filter element 5 is blocked, the oil inlet amount of the subsequent engine oil is unchanged, and the pressure of the engine oil is gradually accumulated in the space surrounded by the mounting seat 2 and the casing 1, and the influence of the pressure of the device is reduced.

The use method (working principle) of the invention is as follows:

during the longitudinal extension of the extending member 17, the extending member 17 further pushes the clamped flanges, thereby improving the tight contact between the flanges.
