Description

Technical Field

[0001] The utility model belongs to the technical field of filter elements, and in particular relates to a fuel filter element. Background Art

[0002] Traditional fuel filter designs typically use a single-layer mesh or screen as the filter medium. While these materials can filter impurities from fuel to a certain extent, their durability and filtration efficiency are limited. The mesh fibers of the mesh or screen material can easily wrinkle when subjected to external forces, causing the entire filter to deform. This deformation not only affects the filter's filtration efficiency but can also damage delicate fuel system components. Filter deformation is particularly problematic in harsh operating environments, such as those with high temperatures, high pressures, or when the fuel contains a large amount of impurities. Due to the limited durability of the mesh or screen material, it is prone to wear and clogging with repeated use. This not only reduces the filter's filtration efficiency but can also shorten the filter's lifespan. Consequently, traditional single-layer filters have low reusability, requiring frequent replacement of the filter or the entire filter, increasing maintenance costs and downtime. Utility Model Content

[0003] In order to solve the problems raised in the above-mentioned background technology, the present invention provides the following technical solutions: a fuel filter element, comprising a filter element body, the filter element body comprising a filter screen and a filter body, an oil channel being opened in the filter body, an oil inlet hole connected to the oil channel being opened on the outer wall of the filter body, and the filter screen being sleeved on the outer wall of the filter body.

[0004] Furthermore, the filter screen includes a mesh filter screen.

[0005] Furthermore, the filter screen is provided with multiple layers.

[0006] Furthermore, the filter screen is provided with two layers.

[0007] Furthermore, the filter screen includes a mesh filter screen and a mesh filter screen, and the mesh filter screen and the mesh filter screen are put on the outer wall of the filter body in any order, and the mesh filter screen and the mesh filter screen are in close contact with each other.

[0008] Furthermore, an annular groove communicating with the oil inlet hole is formed on the outer wall of the filter body.

[0009] Furthermore, the oil inlet holes are evenly distributed on the outer wall of the filter body along the height direction of the filter body.

[0010] Furthermore, the filter screen is made of stainless steel.

[0011] The beneficial effects of the present utility model are as follows: the fuel filter element achieves efficient and uniform filtration of the oil by combining a high-strength stainless steel mesh filter with a filter body with a ring groove design. At the same time, the flexible configuration of multiple layers of filter screens (including mesh and cloth types) not only improves the filtration accuracy, but also enhances the maintainability of the filter element. The clogging problem can be solved by quickly replacing the fine-mesh filter screen, while the outer mesh filter screen ensures the overall structural strength. The tool slot design at the bottom of the filter element facilitates assembly and disassembly using hand-held tools, thereby improving operational convenience. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0021] See also Figure 1-3 The utility model provides the following technical solutions: a fuel filter element, including a filter element body, the filter element body including a filter screen and a filter body 1, an oil channel 2 is opened in the filter body 1, an outer wall of the filter body 1 is provided with an oil inlet hole 3 connected to the oil channel 2, and the filter screen is sleeved on the outer wall of the filter body 1.

[0022] In this embodiment, the filter screen includes a mesh filter screen 4 .

[0023] In the above structure, the mesh filter 4 is evenly distributed with filter holes, which has higher structural strength and avoids deformation.

[0024] In this embodiment, an annular groove 6 communicating with the oil inlet hole 3 is formed on the outer wall of the filter body 1 .

[0025] In this embodiment, the oil inlet holes 3 are evenly distributed on the outer wall of the filter body 1 along the height direction of the filter body 1 .

[0026] In this embodiment, the filter screen is made of stainless steel.

[0027] In this embodiment, a tool groove 7 is provided at the bottom of the filter body 1 .

[0028] In the above structure, the tool groove 7 is in an inner hexagonal shape, a straight shape, a cross shape or other shapes, which is convenient for using a handheld tool to assemble the fuel filter element. Example

[0029] Based on Example 1, please refer to Figure 4-7 , the filter screen is provided with multiple layers.

[0030] In this embodiment, the filter screen is preferably provided with two layers. The above setting is not limiting, and the filter screen can also be provided with three layers, four layers, or more layers.

[0031] Preferably in this embodiment, the filter screen includes a mesh filter screen 4 and a mesh filter screen 5, and the mesh filter screen 4 and the mesh filter screen 5 are sequentially sleeved on the outer wall of the filter body 1, or the mesh filter screen 5 and the mesh filter screen 4 are sequentially sleeved on the outer wall of the filter body 1.

[0032] In the above structure, the mesh filter 4 has evenly distributed filter holes, while the cloth filter 5 has more evenly distributed filter holes. These two filters can be sequentially installed on the outer wall of the filter body 1, and the order can be adjusted according to actual needs. The mesh filter 4 has evenly distributed filter holes, while the cloth filter 5 has more densely distributed filter holes, thereby intercepting finer impurities. When the mesh filter 4 is located outside the cloth filter 5, filter blockage can be quickly resolved by replacing the cloth filter 5. Secondly, the mesh filter 4 can compensate for the poor structural strength of the cloth filter 5.
