[0002] Fuel filters are used to remove impurities from fuel. Also known as oil-water separators and diesel fuel filters, they are made of microporous paper and are used to prevent particulate matter, water, and other impurities from entering the fuel. This protects the precision components of the fuel system from wear and other damage, removes solid impurities such as iron oxide and dust contained in the fuel, prevents fuel system blockage, reduces mechanical wear, ensures stable engine operation, and improves reliability.

[0003] The fuel filter consists of a housing and a top cover. When disassembling the filter element, the top cover is usually unscrewed from the top of the housing. The top cover and the housing are connected by threads. Over time, impurities in the fuel can easily adhere to the outer circumference of the threads, making it difficult to disassemble the top cover. This affects the disassembly of the filter element inside the housing and reduces the efficiency of filter element replacement. Utility Model Content

[0004] This utility model provides a fuel filter device with a replaceable filter element structure to solve the problem that when the top cover and the outer shell are connected by threads, impurities in the oil tend to adhere to the outer circumference of the threads during long-term use, making it difficult to disassemble the top cover, which affects the disassembly of the filter element inside the outer shell and reduces the efficiency of filter element replacement.

[0012] Considering that the top cover and the outer shell are connected by threads, impurities in the oil can easily adhere to the outer circumference of the threads during long-term use, making it difficult to disassemble the top cover. This affects the disassembly of the filter element inside the outer shell and reduces the efficiency of filter element replacement.

[0035] Specifically, the cleaning component 5 includes a turbine 51 located near the top of the inner cavity of the inlet pipe 4 and a vertical rod 52 fixedly installed at the bottom center of the turbine 51. A locking block 53 is fixedly sleeved on the outer periphery of the vertical rod 52 near the bottom end, and a scraper 54 is movably sleeved on the bottom of the locking block 53.

[0036] It is advantageous that the scraper 54, which is movably mounted on the turbine 51, can move circumferentially to clean impurities on the inner surface of the filter element body 9, thus avoiding blockage and affecting the subsequent oil supply effect.

[0037] Specifically, a bracket 521 is rotatably connected to the outer periphery of the upright 52, and the bracket 521 is fixedly connected to the inner wall of the liquid inlet pipe 4.

The bottom of both the locking plate 542 and the scraper 54 is provided with irregular holes 541, and the long strips 545 movably penetrate the inner cavity of the irregular holes 541.

[0040] It is advantageous that by setting bolts 543 and threaded holes 544, the scraper 54 can be easily disassembled and its surface cleaned, which is beneficial for subsequent scraping.

[0041] Working principle: When the filter element in the inner cavity of the outer shell 1 needs to be replaced, the knob 66 ​​can be rotated to rotate the threaded tube 65 fixed on the knob 66. The threaded rod 64 connected to the inner cavity of the threaded tube 65 can move the T-shaped locking block 63 forward under the limit of the two adjacent limiting telescopic rods 631, thereby moving the T-shaped locking block 63 away from the inner cavity of the locking slot. The operation of the other connecting components 6 is as described above and will not be repeated here. When the outer shell 1 and the top cover 2 are separated, the filter element body 9 can be taken out from the inner cavity of the outer shell 1, which facilitates the replacement of the filter element body 9 and improves the efficiency of subsequent replacement of the filter element body 9. During the use of the filter element body 9, the turbine 51 can be rotated under the impact of the oil. The scraper 54 can be rotated by the upright rod 52 fixed on the turbine 51, which can clean the impurities on the inner surface of the filter element body 9 and avoid blockage that affects the subsequent oil supply effect.
