Detailed Description
Referring to fig. 1 to 6, the filter element mistake-proofing structure of the motorcycle air filter comprises an upper shell 1 provided with an air outlet 3 and a lower shell 2 provided with an air inlet 4, wherein a filter element bracket 5 is clamped between the upper shell 1 and the lower shell 2, the filter element bracket 5 comprises an opening 53 communicating inner cavities of the upper shell 1 and the lower shell 2 and a mounting opening 51 facilitating insertion of the filter element 6, and the mounting opening 51 is arranged on the side surface of the filter element bracket 5 and exposed out of the surface of the shell; a hook plate 52 for fixing the filter element 6 is arranged below the opening 53, the hook plates 52 are two opposite and form a channel 8 for inserting the filter element 6 between the two hook plates 52, the filter element 6 enters the channel 8 from the mounting opening 51 and penetrates to the other side surface of the air filter along the hook plates 52, when the filter element 6 is completely inserted into the mounting opening, the bottom surface of the filter element 6 is abutted against the hook plates 52, so that the top surface of the filter element 6 is tightly attached to the bottom wall of the opening 53 through a sealing rubber ring 61, and dirty air entering from the air inlet 4 and containing impurities such as dust, particles and the like is prevented from being discharged into the engine from the air outlet 3 without being filtered by the filter element 6; when the filter element needs to be replaced, the filter element 6 can be directly pulled out from the mounting hole 51 on the surface of the shell for replacement, the shell does not need to be disassembled, and the replacement mode is simple and rapid.
In order to enable the filter element 6 to have only correct installation mode, the two hook plates 52 are relatively inclined to enable the channel 8 to narrow from the installation opening 51, the ends of the filter element 6 with different widths and narrower width are used as insertion ends, and the filter element 6 can be completely inserted into the channel 8 only in the direction of the channel 8 by matching the contour of the filter element 6 with the gradually narrowing channel 8; the side part of the filter element 6 close to the mounting hole 51 is provided with the boss 63 in a downward protruding mode, the mounting hole 51 is provided with the clearance groove 54 corresponding to the boss 63, and due to the fact that the boss 63 and the clearance groove 54 are required to be matched, the filter element can be mounted, the sealing part of the filter element 6 can be arranged below the filter element support in the unique ground direction, the filter element can be mounted in the unique direction and the unique posture and enters the mounting hole through the structure, and various problems caused by the fact that the filter element is mounted in a wrong mode are avoided.
