Description

Technical Field

[0001] The utility model relates to the technical field of filter elements, in particular to a filter element with a long service life. Background Art

[0002] The ash filter is a new type of air filter applied to the ventilation openings of domestic fuel vehicles. Its function is to prevent impurities in the air outside the fuel tank from entering the ventilation pipeline when the carbon canister is desorbed, resulting in the failure of the carbon canister or solenoid valve functions. The above-mentioned fuel vehicles include both traditional energy vehicles powered purely by fuel engines, plug-in hybrid new energy vehicles, and range-extended engine new energy vehicles. According to the publication number: CN219441065U, a filter element is disclosed, which includes a filter medium with a cylindrical surface completely enclosed in a circular tube structure and two non-woven fabric circular sheets. The two non-woven fabric circular sheets are closed on the two end faces of the circular tube structure filter medium to form a barrel-shaped filter element. A central hole is opened in the center of the non-woven fabric circular sheet on the side close to the inner end face of the filter cover, and the non-woven fabric circular sheet on the side close to the inner end face of the filter canister is a solid structure. The production beat of the utility model is fast, and there is almost no harmful gas emission during the production process, and the energy consumption is also very low. At the same time, the filter element with this structure has high structural strength and is also very easy to achieve high filtration efficiency, and can replace the common ash filter element forms and the filter element forms of air suspension filters in the market at the same time. However, there are still some defects in the above technology. For example, the existing filter element is prone to the situation that the filter screen cannot be used continuously because some relatively hard impurities hang on the filter screen body during long-term use due to the lack of a protection structure, and the practicability is poor and needs to be improved.
