Description of the Invention: [Technical Field] The present invention relates to a pump filtering device, and more particularly to a novel pump filtering device for filtering metal impurities at a pump inlet. [Prior Art] According to the low water source extraction of the home water tower, or the water required for the mechanical machine to operate _ lubricating oil extraction, agricultural irrigation water guidance, even the water or lubricant pumping of the engine room of the car, depends on the pump . Pumping is the medium for transporting liquid substances such as water and oil. The most important thing is the smoothness of the conveying pipeline. However, as far as we know, there are pumps for various functions available, for example, automobile engine water or lubricating oil conveying. For pumping, a filter screen will be added at the entrance to achieve the swarf filtering effect when the engine is worn. However, the pump adds a single-layer filter design at the inlet, and the effect of actually filtering the metal impurities is limited to metal swarf larger than the mesh hole. For smaller swarf than the filter mesh, it will still flow into the pump. In the case of daily accumulation, it is easy to shorten the life of the machine. Similarly, the pump used in the water tower for pumping low water to the high point in the home, or the agricultural pump pumped from agricultural water, can also be effectively filtered by metal impurities in the water. The same technical issues are necessary to improve. SUMMARY OF THE INVENTION The present invention generally provides a pump filter for multiple filtration performance for pumping. Another object of the present invention is to provide a pumped 201113430 device that effectively filters fine metal impurities. The pump filter used for the above purpose, the filter body includes a sleeve portion and a retaining edge that are movably sleeved with each other, and the sleeve portion has a sleeve portion and a sleeve portion that is sleeved with the pump inlet The top end has an enlarged retaining edge. The inner surface of the retaining edge is provided with two screens; a first and a second filter screen are arranged in the retaining edge, and a space is formed between the two filter nets, and a magnetic element is arranged in the space; The double impurity filtering effect is formed by the two screens, and supplemented by the magnetic element in the space, the fine metal scraps passing through the first filter can be attached 10 to form the third heavy impurity filtering effect. [Embodiment] The present invention relates to a pump filter. In this embodiment, the pump is mainly used for automobiles, and of course, it can be applied to pumps for mechanical, agricultural or general life fields. First, please refer to the first pumping vehicle 1 〇 shown in the first to fourth figures, including an inlet 12 and an outlet 14, which are connected to each other and communicate with each other; a filter body 20, the body 20 is composed of a The ferrule 22 and a rim 2 4 are formed by being combined with the inlet 12. The body 20 has a sleeve portion 2 2 that is sleeved with the inlet 12, and the top end of the sleeve portion 2 2 extends outwardly to abutting the edge 22 of the edge of the inlet 12, and the sleeve portion 2 2 is close to the flange 2 4 The opening of the end is provided with a preset mesh 2 6 , 2 8 ; the retaining edge 24 corresponds to the shape of the fitting portion 2 2 , including the fitting portion and the abutting flange 2 4 Between the inner faces of the annular retaining edges 24, the inclined 201113430 filter (or curved curved mesh) extending upward in the central direction extends a first mesh 26, the first mesh 26 and the second The aperture of the surface of the filter screen 28 is designed to be the same or different from each other' and the second filter screen 6 6 and the second filter screen 28 are closed to form a space of 3 0; the magnetic element 40 0, can be any geometric shape, but corresponding to the end face of the two filters, in a flat mode, and can use common magnets to reduce the filter cost and enhance the price competitiveness, the magnetic element 4 〇 thickness is equal to Or slightly larger than the height of the space between the two screens, so that the magnetic element 4 is placed on the surface of the first screen 26, and the flange 2 and the sleeve 22 are pushed to the bottom, By the second The restriction of the net 2 8 'forms the effect of the two screens to clamp and fix the magnetic element 4 ’' to thereby dispense a filter for the pump. The above-mentioned pump filter of the present invention is expected to exert the following effects: First, the pump inlet set of the vehicle can pass through the filter sleeve and the mesh filter in the front and back of the filter to achieve impurities. The double filtration effect, together with the first filter and mesh of the first filter line, is designed from the center to the outside or to the solitary curve, which can slow down the flow rate of the liquid and body, making the impurities in the liquid relatively more susceptible to the surface of the filter. . Secondly, if the second filter mesh of the retaining edge is smaller than the first mesh of the retaining edge, a safer triple filtering effect can be obtained. Thirdly, the filter is placed in the space of the two filter enclosures, and an additional magnetic element is added to magnetize the fine metal scraps that cannot be filtered by the outer filter, so that the metal impurities contained in the liquid are completely The attraction of the magnetic element 'naturally increases the service life of the pump to form a quadruple filtration effect. In summary, the pump filter of the present invention, the simple two-layer filter combined with the magnetic element 201113430, can effectively prevent the metal from escaping the pump shaft, causing the whole machine to be damaged and extended. The service life of the pump, the novel structural design of this case is not only unprecedented, but also achieves the number of filtering effects, more in line with the progressive provisions; the job is, the inventor has the above instructions and drawings according to law, to the bureau To file an application for a patent for invention, please ask your review committee to agree with the case. 201113430 [Simplified description of the drawings] The first figure is an exploded view of the structure of the filter and the pump of the present invention.
