Specific embodiment

As shown in Figs 1-4, including filter device and blowdown apparatus 12, filter device for filtering air in impurity, row Dirty device 12 is for collecting the impurity filtered out and impurity being extracted out air cleaner, and filter device is by grade one filter 11 and two Grade filter 10 forms, and grade one filter 11 may filter that out that biggish impurity in air, secondary filter 10 may filter that out air In lesser impurity, filtered air is cleaner twice for process, so as to avoid the abrasion of engine, wherein by-pass filtration Device is made of 11 whirlwind cone 5 and whirlwind stick 4, and whirlwind stick 4 is placed in whirlwind cone 5, and 4 outer surface integrally casting of whirlwind stick has spiral Channel, 4 upper and lower ends of whirlwind stick are air outlet, and it is air inlet at 5 upper portion side walls that whirlwind, which is bored, and when engine start can suck inside The air of air, the outside can be sucked from air inlet, and after helical duct, biggish impurity can in centrifugal force and again in air It being fallen under the double action of power in blowdown apparatus 12, the air by preliminary impurity elimination can be drawn into whirlwind stick 4 from air outlet, And be sent into secondary filter 10 from air outlet, secondary filter 10 includes filter case 3, filter core 2 and filter core lid 1, is passed through The air of primary filtration can enter from the air inlet position of 3 lower part of filter case, after the filtering again of filtration core 2, clean sky Gas can be from the air throttle for being sent into engine from the escape pipe on filter core lid 1, and wherein filter core 2 includes filter paper 14, media filtration layer 13 and support plate 15, filter core 2 be formed by stacking by least one filter paper 14, media filtration layer 13 and support plate 15, filter paper 14 be arranged Between media filtration layer 13 and support plate 15, filter paper 14 is fixed on 15 top of support plate, and media filtration layer 13 is fixed on filter paper 14 tops, 14 closed end of filter paper are gas outlet, and gas outlet is used for outlet, and 14 open end of filter paper is for air inlet and to shake out impurity Air inlet, is uniformly provided at least one filter hole on the media filtration layer 13 and filter paper 14, the air inlet of filter core 2 when installation It places downward, can cooperate and impurity is shaken off out filter core 2 under the shake of vehicle body and the double action of gravity, when engine misses, Engine no longer air-breathing, the filter core 2 shaken off out drops into whirlwind stick 4, and falls into blowdown apparatus 12 from whirlwind stick 4, wherein Blowdown apparatus 12 includes dust seal lid 6, dust storehouse 8 and takes out dirt pump 9, is provided at least one dust fall hole on dust seal lid 6 7, the impurity in filter device can be fallen into dust storehouse 8 from dust fall hole 7, and dust storehouse 8 is funnel-form, and dust can be from dust storehouse 8 Top focuses on 8 bottom of dust storehouse, then by 9 extraction of pumping dirt pump, thus achieve the purpose that it is self-cleaning, avoid because impurity is excessive and The case where being unpicked and washed or being replaced.
