[0008] When in use, the oil filter in the engine component of the automobile is tested, and the sealing cylinders on both sides of the fixed cylinder that are engaged in the engaging grooves are pulled. The sealing cylinders are deformed and move away from the engaging grooves through the sealing spring tube. At this time, the sealing cover is rotated and unscrewed from the side wall of the fixed cylinder. The oil filter with the same inner diameter as the fixed cylinder is placed in the fixed cylinder. Then the sealing cover is screwed into both sides of the fixed cylinder, and the sealing cylinder is loosened. The sealing cylinder is elastically reset and engaged into the engaging groove through the sealing spring tube. The sealing spring tube is connected with the placement port through the sealing cylinder to complete the fixed placement of the oil filter.

[0009] Preferably, the diversion mechanism includes a liquid pump and a liquid supply pipe, the liquid pump is arranged on the side wall of the liquid storage tank, the liquid pump extraction end is penetrated through the inner wall of the liquid storage tank, the liquid supply pipe penetrates the detection platform and is connected between the sealing spring tube and the liquid discharge end of the liquid pump; the liquid discharge mechanism includes a liquid outlet pipe and a reflux pipe, the liquid outlet pipe is arranged on the side of the detection platform away from the liquid supply pipe, the liquid outlet pipe penetrates the detection platform and is connected with the sealing spring tube, and the reflux pipe is connected to the end of the liquid outlet pipe close to the liquid storage tank; the reflux mechanism includes a reflux pump, a liquid suction pipe, a connecting rod and an air bag container, the reflux pump is arranged on the side wall of the liquid storage tank, the liquid discharge end of the reflux pump is penetrated through the inner wall of the liquid storage tank, the connecting rod is arranged on the bottom wall of the detection platform at one end close to the reflux pump, and the air bag container is arranged at the connecting rod away from the detection platform on one side, the liquid extraction pipe is connected between the airbag container and the liquid extraction end of the reflux pump, and the end of the reflux pipe away from the liquid outlet pipe is connected to the liquid extraction pipe; the adsorption mechanism includes a semicircular hollow sphere, a guide rod, a soft iron hollow sphere, a white coating, an adsorption electromagnet and a guide spring. Multiple groups of the semicircular hollow spheres are penetrated on the side of the liquid storage tank away from the reflux pump, and the semicircular hollow spheres are arranged in an inclined straight line on the side wall of the liquid storage tank. The guide rod is penetrated on the side wall of the semicircular hollow sphere, the soft iron hollow sphere is arranged on the side of the guide rod close to the liquid storage tank, the white coating is arranged on the side wall of the soft iron hollow sphere, the adsorption electromagnet is arranged inside the soft iron hollow sphere, and the guide spring is arranged between the soft iron hollow sphere and the inner wall of the end of the liquid storage tank away from the semicircular hollow sphere.

[0010] When in use, engine oil containing metal particles is added to the reservoir tank to facilitate testing of the oil filter's ability to filter metal particles. In the initial state, the guide spring is extended, and the guide rod slides along the semicircular hollow sphere to drive the soft iron hollow sphere to be placed inside the semicircular hollow sphere, and the guide rod extends out of the reservoir tank. When the engine oil containing metal particles enters the reservoir tank, the density of the metal particles in the engine oil is detected, and the adsorption electromagnet is energized to generate magnetism, and the adsorption electromagnet magnetizes the soft iron hollow sphere. After being magnetized, the soft iron hollow sphere generates magnetism and pushes the guide rod. The guide rod is deformed by the guide spring to drive the soft iron hollow sphere to move back and forth inside the engine oil containing metal particles to adsorb the metal particles in the engine oil. After the metal particles inside the engine oil are mixed with the engine oil, the metal particles usually undergo a period of friction and oxidation, and a layer of oxide or carbide may form on the surface, resulting in color loss. The color becomes darker, appearing black or dark gray. After the soft iron hollow sphere reciprocates inside the liquid storage tank for the time required by the user, the engine oil inside the liquid storage tank is emptied, and the reflux pump draws the engine oil inside the liquid storage tank through the discharge end, and the engine oil inside the liquid storage tank enters the air bag container through the liquid extraction tube and is placed. Through the white coating applied on the outer side of the soft iron hollow sphere, it is easier to see the density of metal particles adsorbed on the surface of the soft iron hollow sphere, so as to facilitate the detection of the filtering ability of the oil filter for metal particles. The metal particles adsorbed on the surface of the soft iron hollow sphere are observed and recorded through the glass layer on the side wall of the liquid storage tank, and then the reflux pump reverses to draw the engine oil inside the air bag container back to the liquid storage tank through the liquid extraction tube for placement. The adsorption electromagnet is powered off and demagnetized, and the metal particles on the surface of the soft iron hollow sphere fall off into the engine oil. The guide rod is released, and the guide rod is reset to the inside of the semicircular hollow sphere due to the deformation of the guide spring for placement.

[0011] The liquid extraction pump extracts the engine oil containing metal particles in the liquid storage tank through the extraction end, and the engine oil containing metal particles enters the sealed spring tube through the liquid supply pipe. The sealed spring tube transports the engine oil containing metal particles to the fixed tube through the placement port through the sealing tube. The engine oil containing metal particles flows into the liquid outlet pipe after being filtered by the oil filter. The liquid outlet pipe transports the engine oil filtered by the oil filter to the return pipe. The return pipe transports the filtered engine oil to the air bag container through the liquid extraction pipe for temporary storage. When the engine oil in the liquid storage tank is completely extracted, the reflux pump pumps the engine oil temporarily stored in the air bag container back to the liquid storage tank through the liquid extraction pipe, and the adsorption electromagnet is energized to generate magnetism, and the adsorption electromagnet magnetizes the soft iron hollow sphere. The core sphere generates magnetism and pushes the guide rod. The guide rod drives the soft iron hollow sphere into the filtered oil through the deformation of the guide spring. The soft iron hollow sphere absorbs metal particles in the oil through magnetic force, pushing the guide rod to drive the soft iron hollow sphere to move back and forth in the filtered oil. After the movement time of the soft iron hollow sphere meets the user's requirements, the reflux pump reverses and draws the oil in the storage tank through the discharge end through the liquid extraction tube into the air bag container for placement. Then the operator observes the density of the metal particles on the surface of the soft iron hollow sphere through the glass layer on the side wall of the storage tank and records it, and then compares it with the metal particles adsorbed on the surface of the soft iron hollow sphere recorded previously, so as to detect the oil filter's filtering ability for metal particles contained in the oil.

[0012] Specifically, a controller is provided on the side wall of the detection platform.

[0013] Wherein, the controller is electrically connected to the liquid pump, the reflux pump and the adsorption electromagnet respectively.

[0014] Preferably, the model of the controller is SYC89C52RC-401.

[0015] The beneficial effects achieved by adopting the above structure are as follows:

[0016] Compared with the prior art, the present invention adopts magnetic adsorption force and turnover temporary storage. Under the action of the white coating applied on the surface of the soft iron hollow sphere, the density of metal particles inside the oil before and after filtration is compared. In certain specific types of automobiles, multiple oil filters are used. By setting multiple sets of fixed cylinders on the wall of the test bench, the filtering capacity of multiple sets of oil filters in a specific type of automobile can be tested synchronously, thereby detecting the filtering conditions of multiple sets of oil filters on specific types of automobile oil, which is convenient for reducing the probability of wear of engine parts of specific types of automobiles due to the friction of metal particles caused by the defects of the filtering capacity of multiple sets of oil filters. In addition, under the setting of the turnover type liquid flow mechanism, the filtering capacity of the oil filter is more accurately detected by avoiding the mixing of the oil before and after filtration. The guide rod slides along the semicircular hollow sphere to drive the soft iron hollow sphere to be placed inside the semicircular hollow sphere. The guide rod extends out of the liquid storage tank. When the oil containing metal particles enters the storage tank, the oil containing metal particles enters the storage tank. After the liquid tank is filled, the density of metal particles in the engine oil is detected, the adsorption electromagnet is energized to generate magnetism, the adsorption electromagnet magnetizes the soft iron hollow sphere, and the soft iron hollow sphere generates magnetism after being magnetized, pushing the guide rod, and the guide rod deforms through the guide spring to drive the soft iron hollow sphere to move back and forth in the engine oil containing metal particles, and the metal particles in the engine oil are adsorbed. After the metal particles in the engine oil are mixed with the engine oil, the metal particles usually undergo a period of friction and oxidation, and a layer of oxide or Carbides cause the color to darken and appear black or dark gray. After the soft iron hollow sphere reciprocates inside the liquid storage tank for the time required by the user, the engine oil inside the liquid storage tank is drained, and the reflux pump draws the engine oil inside the liquid storage tank through the discharge end. The engine oil inside the liquid storage tank enters the air bag container through the extraction tube and is placed. The white coating applied to the outside of the soft iron hollow sphere makes it easier to see the density of metal particles adsorbed on the surface of the soft iron hollow sphere, thereby facilitating the detection of the oil filter's filtering ability for metal particles.
