ABSTRACT:
An air ion emitter has a needle-like emitter coaxially mounted within a cylindrical barrel. The barrel is pivoted and rotatable on the base so that it can be pointed in any direction and angle, as at a collector at opposite plurality. The end of the barrel has venturi slots therein so that air flow induced by the emission of ions is radially inward and then axially out the end to scour the needle point and keep it sharp.
