Description

Air filter gasket Technical Field The utility model relates to the technical field of gaskets, in particular to an air filter gasket. Background The air filter filters out impurities such as dust and sand particles suspended in air, prevents the impurities from entering the engine, provides clean and sufficient air for the engine, and a gasket is needed at the joint of an air outlet of the air filter and an air inlet pipe of the engine, so that a joint gap between the air outlet of the air filter and the air inlet pipe of the engine is sealed, unfiltered air is prevented from being mixed into the air inlet pipe from an interface gap, and the impurities are prevented from entering an engine cylinder body. The chinese patent with publication number of CN117307715A discloses a rubber gasket, including two half rubber gaskets, and two half rubber gaskets are for controlling the laminating setting, two be equipped with joint mechanism between the half rubber gasket, be located left side the top of half rubber gasket is close to front and back both sides department and all sets up flutedly, just open slot has been seted up on the right side of recess, this patent is convenient for dismantle two half rubber gaskets through the mutually supporting between recess, open slot, rubber ball and the connecting rod to when one of them half rubber gasket wearing and tearing are serious, can dismantle it and change, reduce use cost, simultaneously, through the detachable setting between two half rubber gaskets, improved the convenience of rubber gasket installation, be favorable to improving installation effectiveness, but above-mentioned patent is owing to adopting the mode of concatenation equipment to form complete gasket for the gasket concatenation department has the gap, and then makes the gasket in the use, very easy deformation, with this makes the gap grow, has reduced the sealed effect of rubber gasket, has for this reason we put forward a empty filter gasket.
