Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, a filter for use in an oil tank, including filter cartridge 1, filter cartridge 1 welded fastening is at the lower wall of oil tank, filter cartridge 1 is square columnar hollow structure, filter cartridge 1 internal seal sliding connection has piston 2, piston 2 can slide in filter cartridge 1 internal seal, filter cartridge 1 one end is seted up has filtration pore 3, filter cartridge 1 has seted up first spout 4 on being equipped with the lateral wall of filtration pore 3, sliding connection has first slider 5 in first spout 4, the welding has slide 6 on the first slider 5, filter cartridge 1 inner wall welded fastening has fixed plate 7, fixed plate 7 is located slide 6 one side of keeping away from filtration pore 3, welded fastening has spring 8 on fixed plate 7, the one end that fixed plate 7 was kept away from to spring 8 and slide 6 welded fastening, the square hole has been seted up on slide 6, the interior veneer gluing of square hole has filter screen 13, piston 2 and slide 6 are provided with the stifled device jointly.

Prevent stifled device and include dwang 12, dwang 12 uses the round pin hub to rotate and connects on piston 2, has seted up second spout 9 on the slide 6, and sliding connection has second slider 10 in the second spout 9, and welded fastening has scraper blade 11 on the second slider 10, and the one end that piston 2 was kept away from to dwang 12 uses the round pin hub to rotate to be connected on scraper blade 11, and scraper blade 11 can be scraped the impurity that adheres to on filter screen 13 down, avoids producing the jam.

The scraper 11 is in a strip structure, and brush hair is glued on one surface of the scraper 11 away from the rotating rod 12; the impurities on the filter screen 13 can be better scraped by the scraping; the area of the filter screen 13 is larger than that of the filter holes 3, so that when the piston 2 moves fuel oil in the filter box 1 to extrude outwards, the fuel oil can rapidly move to the outside of the filter box 1; a counterweight block 14 is fixed on the piston 2 in a gluing way, so that the piston 2 can better move along with the movement of the vehicle in the movement process; constant pressure hole 15 has been seted up to one side that filter cartridge 1 kept away from filtration pore 3, guarantees that the pressure on filter cartridge 1 right side remains stable for piston 2 can normal motion.

The vehicle can inevitably generate actions such as acceleration, turning, braking and the like in the running process, the filter box 1 is fixed at the bottom of the oil tank, so that the filter box 1 is submerged in fuel oil, and the piston 2 in the filter box 1 can move relatively because the filter box 1 cannot move relative to the oil tank, so that the space of the piston 2 close to one side of the filter hole 3 can be changed when the vehicle accelerates, turns, brakes and the like due to the fact that the piston 2 slides in the filter box 1; when the piston 2 is far away from the filter hole 3, the space on the right side of the piston 1 in the filter box 1 is increased (the description is given by taking fig. 1 as an example, the same is applied below), and when the piston 2 is positioned on the left side of the filter box 1, the rotating rod 12 which is rotatably connected with the piston 2 pulls the sliding plate 6 to move downwards, so that the filter screen 13 is not abutted against the filter hole 3, and the fuel in the oil tank can rapidly enter the filter box 1;

when the piston 2 moves rightwards, the rotating rod 12 rotates anticlockwise to enable the scraper 11 to move upwards, due to the existence of the spring 8, the spring 8 pushes the sliding plate 6 and the second sliding block 10 to synchronously slide upwards until the first sliding block 5 moves to the uppermost end of the first sliding chute 4, at the moment, the sliding plate 6 generates a shielding effect on the filtering holes 3, so that fuel oil in the filtering box 1 cannot directly flow out of the filtering holes 3, and the filtering net 13 is opposite to the filtering holes 3; the piston 2 continues to move rightwards, the rotating rod 12 continues to rotate to drive the scraper 11 and the second slider 10 to move upwards relative to the second sliding chute 9, in the process, the piston 2 continuously reduces the space on the right side of the filter box 1, fuel oil on the right side of the filter box 1 is extruded out, and the fuel oil inevitably passes through the filter screen 13 when passing through the filter holes 3, so that impurities mixed in the fuel oil can be filtered on the filter screen 13;

when the piston 2 moves leftwards again, the rotating rod 12 rotates to drive the scraper 11 to move downwards, and due to the existence of the spring 8, the sliding plate 6 does not move along with the scraper 11 at the moment, and only the scraper 11 moves downwards to scrape off impurities attached to the filter screen 13 and bring the impurities to the vicinity of the fixing plate 7, so that the filter screen 13 is prevented from being blocked by excessive impurities on the filter screen 13.

To sum up: the utility model discloses a filter is at the car operation in-process, and piston 2 can be continuous in filter cartridge 1 reciprocating motion repeated above-mentioned action, and then strain the impurity of mixing in the fuel.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
