Abstract
A hand-holdable electro-kinetic electro-static ionic air refreshener-conditioner for a pet shelter or litter box includes a self-contained ion generator that provides electro-kinetically moved air with ions and safe amounts of ozone. The ion generator includes a high voltage pulse generator whose output pulses are coupled between first and second electrode arrays. Preferably the first array comprises one or more pin-like electrodes and the second array comprises one more washer-like electrodes. Preferably a ratio between effective area of an electrode in the second array compared to effective area of an electrode in the first array exceeds about 15:1 and preferably is about 20:1. An electric field produced by the high voltage pulses between the arrays produces an electrostatic flow of ionized air containing safe amounts of ozone. Optionally, a sensor detects odor adjacent the refreshener-conditioner causes the ion generator to be activated when sensed odor exceeds a predetermined threshold. Odor-activation of the ion generator can be open or closed loop. A bias electrode, electrically coupled to the second array electrodes, affects net polarity of ions generated. The outflow of ion…
