An object of the present invention is to provide an ionizer having a cleaning system for cleaning an electrode needle of the ionizer automatically or remotely, while also being compact in size. The cleaning system () has a rotating member () configured to coaxially rotate with the fan (), a plurality of rods (to) attached to the rotating member () such that each rod extends radially from the rotating member, and brushes (to) each attached to the end of each rod. The rotating member () is driven by an electromagnetic solenoid () via a coupling means ().

Ionizer having cleaning system

An electro-magnetic wave shield cover having an array of first yarn members () formed by bundling () ends of polyester fibers around which a tin-plated copper metallic foil () is wound. The second yarn member () is formed by bundlingends of polyester fibers. Doubled-yarn groups (A,B,C,D) of the first yarn members running in the first direction (warp) from upper right to lower left and doubled-yarn groups (A,B,C,D) of the second yarn members () running in the first direction (warp), and doubled-yarn groups () of the first yarn members running in the second direction (weft) from upper left to lower right and doubled-yarn groups () of the second yarn members running in the second (weft) direction are arranged so that the interlacing is made in such a manner that if the doubled-yarn group, running in the one direction is twice disposed beneath the doubled-yarn groups running in the other direction, then it is twice disposed above the latter.
