[0022] Through the above technical solution, when the product is used, the diesel enters the containing groove 31 after passing through the inlet hole 40. At this time, the diesel is located on the outside of the filter element 2, and then enters the inside of the filter element 2 after passing through the filter element 2, and then leaves from the outlet hole 30 to supply fuel to the diesel engine.

[0023] After long-term use, it is possible to determine whether the filter needs to be replaced by observing the side surface of the seat body 3 (mainly) and the end surface of the cover body 4 (auxiliary), so that the filter replacement is more timely, which does not waste the service life of the filter and does not shorten the service life of the diesel engine.

[0024] The transparent base body 3 and cover body 4 are convenient for observation.

[0025] Specifically, the base body 3 and the cover body 4 are fixed by ultrasonic welding, and after installation, the structure has high strength and good sealing performance.

[0033] Specifically, the abutment portion 33 abuts against the inner side surface of the inner sleeve of the filter element 2, the positioning portion 32 abuts against the lower end surface of the inner sleeve of the filter element 2, the accommodating groove 31 abuts against the lower end surface of the outer sleeve of the filter element 2, and the housing 1 abuts against the upper end surface of the filter element 2, thereby fixing the filter element 2 from multiple angles, further preventing the filter element 2 from shaking, and improving stability during use.

[0034] As an improved specific embodiment, the resistance part 33 is made of metal, the resistance part 33 is provided with a connecting part 34 extending outward from the seat body 3, the outer side of the connecting part 34 is provided with a thread, the resistance part 33 and the connecting part 34 are integrally formed, the exit hole 30 passes through the resistance part 33 and the connecting part 34, and the resistance part 33 and the seat body 3 are integrally injection molded.

[0035] Through the above technical solution, the abutment portion 33 and the connection portion 34 are integrally formed, and the structural strength is high; the abutment portion 33 and the seat body 3 are integrally injection molded, and the structural strength is high, which further avoids leakage.

[0036] The outer side of the connection part 34 is provided with a thread for connection with the automobile. After the connection, the connection has high stability, high structural strength, good sealing performance, and convenient connection.

[0037] As an improved specific implementation, a guide notch 331 is provided on the abutment portion 33 .

[0038] Through the above technical solution, the outlet gap 331 is used for filtered diesel to pass through, thereby reducing flow resistance and improving product performance.

[0039] As an improved specific implementation, the cover body 4 is provided with a clamping rod 41 extending outward, the end of the clamping rod 41 is provided with a clamping block 42 , and the entry hole 40 passes through the clamping rod 41 .

[0040] Through the above technical solution, the clamping rod 41 and the clamping block 42 are matched and fixed with the female connector on the car, and the installation efficiency is high.

[0041] Specifically, during installation, firstly, the lower end of the diesel filter is threadedly fixed to the vehicle, and then the clamping rod 41 is inserted into the female head to complete the installation.

[0042] As an improved specific implementation, the cover body 4, the clamping rod 41 and the clamping block 42 are integrally formed.

[0043] Through the above technical solution, the cover body 4, the clamping rod 41 and the clamping block 42 are integrally formed, and the structure has high strength and long service life.

[0044] As an improved specific implementation, the cover body 4 is provided with a positioning block 43 protruding inward, the positioning block 43 is in conflict with the filter element 2, a first passing gap 44 is provided between the positioning block 43 and the filter element 2, and a second passing gap 45 is provided between adjacent positioning blocks 43.

[0045] Through the above technical solution, the positioning block 43 interferes with the filter element 2, and a first passing gap 44 is formed between the positioning block 43 and the filter element 2, so that the diesel can smoothly pass through the first passing gap 44 after entering from the inlet hole 40, and then pass through the second passing gap 45, and then pass through the filtering part of the filter element 2, and leave from the outlet hole 30 after filtration.

[0046] This design ensures that the top of the filter element 2 (i.e., the side facing the cover body 4) is made of rigid material. After the connection is completed, the position of the filter element 2 is stable and there is no shaking. The filtering part of the filter element 2 is located on the side of the seat body 3, which is convenient for personnel to observe and judge.

[0047] As an improved specific implementation, the positioning block 43 is provided with an inclined guide edge 46 on a side facing the first passing gap 44 .

[0048] Through the above technical solution, the guide edge 46 further reduces the flow resistance, increases the flow rate of the diesel flowing from the first passing gap 44 to the second passing gap 45, and improves the product performance.

[0049] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
