Description

Technical Field

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

[0002] The fuel filter element's gland and housing are sealed together to form a single unit. This area is called the sealing section. This sealing process causes the gland material to stretch and bend, damaging even a rust-resistant coating. As the first filter element in the engine's fuel system, the fuel filter is typically mounted on the vehicle's frame, exposed to the elements for extended periods of time. Therefore, corrosion is inevitable at the filter element's sealing section. While this does not affect performance, it can severely impact user experience.

[0003] As domestic market competition intensifies, host customers have increasingly higher requirements for product appearance quality. The internal standards of some high-end customers are even several times higher than industry standards. In order to meet this requirement, manufacturers have to invest in better materials and coatings to meet anti-rust requirements, but this brings huge cost pressure. Utility Model Content

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0026] like Figure 1 and Figure 2 As shown, this embodiment provides a fuel filter, comprising a filter seat 1 and a filter element 2 disposed on the filter seat 1, and further comprising a sealing ring 3 disposed between the filter seat 1 and the filter element 2;

[0027] The filter element 2 includes a housing 21, a gland 22 and a filter element body 23. The filter element body 23 is disposed in the housing 21. The gland 22 is disposed on the open end of the housing 21 through a sealing process. The junction between the gland 22 and the housing 21 is a sealing portion 24.

[0028] The sealing ring 3 includes a ring body 31, and a shielding portion 32 for shielding components is provided on the outer side of the ring body 31. The shielding portion 32 is annular and is coaxially arranged with the ring body 31. The ring body 31 of the sealing ring 3 is arranged between the filter seat 1 and the filter element 2, and the shielding portion 32 of the sealing ring 3 shields the sealing portion 24 of the filter element 2.

[0029] Since the outer side of the ring body 31 of the sealing ring 3 is additionally provided with a shielding portion 32 for shielding components, the components are shielded, and the components are prevented from being directly exposed to the external environment and contacting with media such as rain and snow, which can effectively prevent the components from rusting and solve the problem of rusting of components. In addition, the shielding portion 32 of the sealing ring 3 can shield the sealing portion 24 of the filter element 2, and prevent the sealing portion 24 from being directly exposed to the external environment and contacting with media such as rain and snow, effectively preventing the sealing portion 24 from rusting and solving the problem of rusting of the sealing portion 24 of the filter element 2.

[0030] The shielding portion 32 in this embodiment comprises a top plate 321 connected to the ring body 31 and side plates 322 perpendicularly mounted on the top plate 321. Together, the top plate 321, side plates 322, and the ring body 31 form a receiving groove suitable for components. Specifically, the receiving groove is adapted to the sealing portion 24, which is located within the receiving groove. This arrangement further enhances the shielding and protective effect of the shielding portion 32, ensuring the product's appearance quality requirements.

[0031] In order to improve the aesthetic appearance of the product and further meet the appearance quality requirements of the product, in this embodiment, the corner between the top plate 321 and the side plate 322 is set to be a rounded corner.

[0032] In this embodiment, the cross section of the ring body 31 is rectangular, that is, the ring body 31 of the sealing ring 3 is a rectangular gasket. This configuration expands the sealing contact surface, thereby improving the sealing effect and preventing damage to the filter seat 1 and the filter element 2.

[0033] In order to improve the connection strength, in this embodiment, the ring body 31 and the shielding portion 32 are preferably provided integrally, and the material of the sealing ring 3 is rubber.

[0034] In this embodiment, the thickness of the top plate 321 of the shielding portion 32 is D, and the gap height between the filter seat 1 and the filter element 2 is L, D≤L. This arrangement avoids affecting the assembly of the filter seat 1 and the filter element 2 due to the top plate 321 being too thick, thereby ensuring the assembly effect.

[0035] The fuel filter in this embodiment further includes a water collection cup 4 , which is disposed on the housing 21 .

[0036] To sum up, since the fuel filter in this embodiment is provided with a sealing ring 3, the shielding portion 32 of the sealing ring 3 can shield the sealing portion 24 of the filter element 2, thereby preventing the sealing portion 24 from being directly exposed to the external environment and contacting media such as rain and snow, and effectively preventing the sealing portion 24 from rusting. Therefore, the problem of rusting of the sealing portion 24 of the filter element 2 is effectively solved.

[0037] The above is only a preferred embodiment of the fuel filter and its sealing ring of the present invention. There are many more embodiments that are not described here in detail. The present invention is not limited to the above specific implementation methods. Various modifications made by ordinary technicians in this field based on the above concept without creative work fall within the scope of protection of the present invention.
