NOVELTY - The utility model claims an energy storage electric field purifying device, comprising a shell, a primary filter plate, a polar plate, a dust collecting plate, an air outlet plate, a connecting plug, a lead; a charging pile and a negative ion generator; the graphene coating process is set on the basis of the high molecular refractory material dust collecting material; under the condition of passive (non-high voltage power supply continuous power supply), it greatly enhances the induction electric field strength and persistent storage capacity of the dust collecting plate under the mutual inductance effect between the plate spacing; can be in the passive state, the filter core once charging (several seconds of action time) can be stored more than month, through the second storage technology of breakthrough, only needs to install small negative ion generator at the air outlet, at the same time, the whole cost of the electrostatic filter is greatly reduced, and suitable for household; Commercial independent machine purifier and purifying and sterilizing system of large bus, small vehicle and other vehicle.
