Description

Air inlet filter element structure of fuel engine unit Technical Field The utility model relates to an air inlet filter element structure, in particular to an air inlet filter element structure of a fuel engine unit. Background The air inlet filter element structure of the fuel engine unit mainly comprises a filter element and a shell, wherein the filter element is a core filter component, and the shell provides protection for the filter element. The filter element in ‌ filter element structure usually adopts porous medium material (such as paper or fiber material) to intercept dust, sand and other impurities in air by physical blocking mode, and has the characteristics of good air permeability and high filtering precision, but needs to be replaced periodically to avoid blockage. The common filter element is connected with the shell through screws, namely, after the filter element is installed on a vent pipe of the shell, the filter element is fastened through screws, so that the installation clearance is reduced. When maintenance is carried out, the filter element is disassembled, so that part of dust can fall off and possibly fall into screw holes, the subsequent screwing is not in place, the filter element and the shell are not firmly connected and are overlarge in intermittence, the filtering effect of the filter element can be reduced, and the protection of the engine is not facilitated.
