Abstract:
1. An electronic driving circuit coupled to an air treatment device for emitting an air treatment into a space, said driving circuit comprising: an actuating element and a power source, said actuating element comprising a piezoelectric element, wherein said piezoelectric element comprises a round piezoelectric disc having a round hole concentrically disposed therethrough, said piezoelectric element being juxtaposable with the air treatment material; a step up transformer, said transformer having a dual input with clockwise and counter-clockwise windings and a common center tap in electrical communication with a power supply; two input signals provided to the transformer 180 degrees out of phase with each other, and wherein said transformer provides an AC signal to said piezoelectric element; and an inductor connected to the transformer and disposed intermediate said transformer and said piezoelectric element; wherein said inductor uses the AC signal generated by the transformer to drive the piezoelectric element with a substantially pure sinusoidal waveform, and wherein the inductor and the piezoelectric element comprises a LC circuit having a resonant frequency and being operable at a frequency generally equivalent said resonant frequency, thereby causing movement of said piezoelectric element relative to the air treatment material.
