Abstract
A small personal appliance is wholly contained within a unitary housing that is fully supported by its contact blades being plugged into a wall outlet. The housing includes needles for ionizing the ambient atmosphere and a carbon foam pad for collecting the ionized air. A drive circuit generates cyclically recurring pulses having a voltage which is high enough to ionize the air and low enough to preclude a formation of ozone.
Claims9
An ionizer comprising a small and light weight housing with a pair of conventional electrical power plug contact blades extending therefrom, whereby the housing may be mounted by pressing the blades into a wall outlet, a pocket formed in the housing for receiving an electrically conductive collector pad while exposing a substantial surface of said collector pad to the ambient air, at least one opening formed in the housing at a location which is remote from said collector pad, at least one ion needle located at the opening and positioned to direct a stream of ions out of said opening, drive means for cyclically applying drive pulses to said needle to energize them with a negative potential which is high enough to create negative ions, but which is not high enough to create ozone, and means for applying a positive voltage to said collector pad.
An ionizer comprising a generally elongated housing having a pocket formed therein and at one end thereof with holes formed in said housing at a point that is remote from said pocket, said pocket having an opening extending along a part of each of two opposing sides and a front thereof for receiving a collector pad, and a frame for supporting the edges of the bottom of said collector pad, whereby substantially the entire bottom of said collector pad and at least part of each of three sides of said pad are exposed to ambient air, and means for generating a stream of negative ions emanating from said holes, said collector pad being biased by a positive potential.
A small personal appliance which is totally self contained within a housing that may be plug-in mounted on a wall outlet, needles means in said housing for driving ionized air out of said housing and into the ambient air, collector means at an opening in said housing for collection ions from said ambient air, and drive means for cyclically applying a negative potential to said needles and a positive potential to said collector means, the voltage difference between said positive and negative potentials being high enough to ionize the air and low enough not to form ozone.
