The invention discloses an air filter. The air filter comprises a cavity, a filter element, a cover body which covers an opening of the cavity, and a filter element bracket which is inserted into the cavity, wherein fixing grooves formed by two long plates are formed on the upper inner wall and the lower inner wall of the cavity; the filter element bracket is clamped in the fixing grooves to which the filter element bracket belongs; transverse plates which are pressed against the end faces of the long plates and used for limiting the vertical motion of the filter element bracket are arranged on the upper and lower parts of the side face of the filter element bracket; a baffle plate which is pressed against the outer end faces of the long plates and used for limiting the motion of the filter element bracket in the forward direction is arranged on the side face of the bracket; and the cover body is pressed against the outer side face of the filter element bracket. A plurality of positions are in positioning fit, so that the filter element and the filter element bracket have a unique assembly position and are stably and reliably matched, and a filtering effect is ensured; and long and short plates are combined for positioning, so that a large space is formed at the opening of the cavity when the filter element bracket is taken out, and hands can conveniently stretch into the cavity to clean dust.
Description
technical field [0001] The invention relates to a filter, in particular to an air filter suitable for engine air intake systems of vehicles such as motorcycles. Background technique [0002] The air filter is one of the indispensable key components on motorcycles and other vehicles. The outside air enters the air filter, and the dust and water vapor in the air are filtered out through it, and then the filtered air is sent to the engine to assist The operation of oil and gas combustion, the performance of the air filter is related to many aspects such as the power, economy and intake noise of the engine. [0003] The air filter is generally composed of a cavity, a shell cover, an air intake pipe, an air outlet pipe, a filter element and a filter element bracket. In order to prolong the service life of the air filter and reduce maintenance costs, the filter element and the filter element bracket are detachable and installed on In the filter cavity, the traditional air filter ...
