DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] Referring to Figures 1-4 , the present application provides an embodiment:

[0025] A long-life durable diesel filter, comprising a shell 1, the upper end of the shell 1 is provided with a replacement mechanism 5, the replacement mechanism 5 comprises a rotating block 506, a plurality of inclined grooves 505 are formed in the upper end of the rotating block 506, a plurality of clamping blocks 504 are slidably arranged in the plurality of inclined grooves 505, one side of one of the plurality of clamping blocks 504 is fixedly provided with a pull rod 501, and the pull rod 501 is externally sleeved with a spring 502;

[0026] The upper end of the shell 1 is provided with a top cover 2, a plurality of clamping grooves 503 are formed in the lower end of the top cover 2, the rotating block 506 is rotatably arranged at the upper end of the shell 1, the plurality of clamping blocks 504 are slidably arranged at the upper end of the shell 1, one side of the spring 502 is fixedly arranged on one of the plurality of clamping blocks 504 close to the pull rod 501, the other side of the spring 502 is fixedly arranged on the shell 1 close to the pull rod 501, the pull rod 501 is slidably arranged on one side of the shell 1, and the two opposite sides of the plurality of clamping blocks 504 are respectively arranged on the two opposite sides of the plurality of clamping grooves 503.

[0027] Specifically, in the assembly phase, the filter cartridge 6 is screwed into the lower end of the top cover 2 to form an integrated assembly. When the lower end of the assembly is lowered to align with the upper end of the shell 1, the outer wall of the top cover 2 first contacts the inclined surface of the clamping block 504. Due to the opposite inclined design of the clamping block 504, the downward force of the top cover 2 will force the clamping block 504 to slide reversely in the shell 1, while driving the rotating block 506 to rotate synchronously. During this process, the spring 502 is compressed and stored, and when the top cover 2 is completely seated in the shell 1, the spring 502 releases the elastic force quickly, pushing the clamping block 504 to reset, and the rotating block 506 rotates back, making the clamping block 504 accurately embedded in the clamping groove 503 of the top cover 2, completing the buckle locking. During this period, the sealing sheet 8 is deformed under pressure, tightly filling the gap between the top cover 2 and the shell 1, achieving zero-leakage sealing. At the same time, the plug 9 is accurately embedded in the bottom of the filter cartridge 6, forming a double-sealing structure with the sealing ring 10, ensuring that diesel fuel can only pass through the filter cartridge 6 to complete the purification process, and it can still maintain stability under the pressure and vibration generated by the flow of diesel fuel, reducing filter failures caused by loose connections, and prolonging the service life of the filter.

[0028] When the filter cartridge 6 needs to be replaced, pull the pull rod 501 to trigger the unlocking, and the pull rod 501 drives the connected clamping block 504 to slide along the inclined groove 505. The sliding of the clamping block 504 will cause the rotating block 506 to rotate inside the shell 1, thereby driving the remaining clamping blocks 504 to slide reversely synchronously. As the clamping blocks 504 gradually exit the clamping grooves 503, the locking state of the top cover 2 and the shell 1 is released, and then the assembly can be easily separated to remove the filter cartridge 6 for cleaning or replacement. The entire process does not require additional tools and reduces the time and difficulty of replacing the filter cartridge 6, improving maintenance efficiency.

[0029] Referring to Figures 1-3 , the top cover 2 has an oil outlet 4 at the upper end, and the shell 1 has an oil inlet 3 fixed on one side of the upper end. The oil inlet 3 is arranged inside the top cover 2. The shell 1 has a sealing ring 10 fixed at the lower end, and a residue discharge pipe 7 fixed on one side of the lower end. The top cover 2 and the shell 1 are provided with a sealing sheet 8, and the top cover 2 has a filter cartridge 6 screwed at the lower end. The shell 1 has a plug 9 fixed at the lower end.

[0030] Specifically, the diesel containing impurities enters from the oil inlet 3, is filtered by the filter cartridge 6, the impurities are intercepted inside the filter cartridge 6, the pure diesel passes through the filter cartridge 6 into the inside of the top cover 2, and finally flows out from the oil outlet 4 to be delivered to the engine. In this process, the insert block 9 can support and position the filter cartridge 6 to some extent to ensure the stability of the filter cartridge 6 during the working process. The double sealing design of the sealing sheet 8 and the sealing ring 10 effectively prevents diesel leakage, ensures the sealing performance and working stability of the filter, avoids fuel waste and environmental pollution caused by diesel leakage, and also ensures the filtering effect. At the same time, the part of impurities and moisture accumulated at the bottom of the shell 1 can be discharged through the slag discharge pipe 7, which reduces the accumulation of impurities inside the filter, reduces the plugging frequency of the filter cartridge 6, helps to maintain the filtering performance of the filter, and further prolongs the service life of the filter cartridge 6 and the entire filter.

[0031] Working principle: when connecting the shell 1 and the top cover 2, the filter cartridge 6 is first screwed into the lower end of the top cover 2, then the lower end of the top cover 2 is aligned with the upper end of the shell 1, and the outer wall of the top cover 2 will contact the clamping block 504. Since the two opposite sides of the clamping block 504 are inclined to some extent, when they contact the outer wall of the top cover 2, the clamping block 504 will slide in the opposite direction inside the shell 1, and the rotating block 506 will rotate inside the shell 1, and the spring 502 will be compressed. When the top cover 2 and the shell 1 are connected, the spring 502 rebounds to push the clamping block 504 back to its original position, so that the rotating block 506 rotates back to cause the clamping block 504 to be embedded in the clamping groove 503, thereby achieving stable connection between the top cover 2 and the shell 1. At the same time, the sealing sheet 8 ensures the sealing between the two to prevent diesel leakage. In addition, the insert block 9 is embedded in the lower end of the filter cartridge 6, and the sealing ring 10 ensures the sealing between the bottom of the filter cartridge 6 and the shell 1, so that diesel can only be filtered through the filter cartridge 6.

[0032] Secondly, when the filter cartridge 6 needs to be replaced, the clamping block 504 is pulled to slide along with the pull rod 501, and the clamping block 504 will slide in the inclined groove 505 to cause the rotating block 506 to rotate inside the shell 1. The rotation of the rotating block 506 will cause the multiple clamping blocks 504 to slide in the opposite direction inside the shell 1 synchronously, so that the connection between the clamping block 504 and the clamping groove 503 is gradually released. At this time, the connection between the top cover 2 and the shell 1 can be released, and then the filter cartridge 6 can be removed for cleaning or replacement.

[0033] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
