NOVELTY - The utility model claims a negative ion energy-saving ceramic tile, comprising a phase change heat storage material layer, graphite heat conducting layer, radiating body and anion surface material layer on the surface of the radiating body layer with negative ion fabric layer; the radiating body layer on the back surface of the longitudinal and transverse interval provided with multiple grooves, multiple longitudinal grooves and multiple transverse grooves are communicated through a longitudinal groove and a transverse groove in turn filled with phase change heat storage material layer and the graphene conducting layer in the groove from the back. The utility model combines the graphene conducting layer and a radiating body layer, phase change heat storage material can better exert the constant adjusting function, reduce energy consumption pressure; this utility model has energy-saving negative ion ceramic tile lasting negative ion releasing effect and good energy-saving effect.
