Rectilinear turbulent flow type air purifier

An air purifier comprised of a housing, a front cover, a front wire gauze filter, an anion generating pin board, a dust collector, and an active carbon filter, wherein:

• said housing comprises a plurality of parallel tracks horizontally disposed at different elevations for mounting said front wire gauze filter, said anion generating pin board, said dust collector, and said active carbon filter, a plurality of arched metal springs fixedly fastened to said parallel tracks for connecting power supply to said anion generating pin board and said dust collector, a vertical side track for mounting a side cover to stop said front wire gauze filter, said anion generating pin board, said dust collector, and said active carbon filter in said parallel tracks, a micro switch for ON/OFF power supply, said micro switch being triggered to turn on power supply when said side cover is installed, or to turn off power supply when said side cover is removed from said vertical side track;
• said dust collector has a plurality of equally spaced round holes over the whole area thereof, and is controlled to produce positive ions;
• said anion generating pin board has a plurality of triangular projecting plates perpendicularly raised from one side thereof and respectively aimed at the center of every four adjacent round holes of said dust collector, and is controlled to produce negative ions.
