The present invention relates to a negative ion generating device, which mainly comprises an energy body, which is a piece or a powder body made of a natural ore material through a ceramic nanotechnology； In combination with the energy body, the coupling member is provided with an accommodating space for inserting and fixing the energy body. Through the high-frequency oscillatory physical properties of the natural ore material itself, the water molecules in the air are decomposed into a positively charged hydrogen ion and a negatively charged hydroxide ion (negative ion). The energy body can be used to generate a negative ion released, thereby exerting a health care effect on the human body.本創作係關於一種負離子生成裝置，主要係設有一能量體，該能量體係為一天然礦石材料經由一陶瓷奈米技術所製成的一塊狀體或一粉末體；一結合件，其係用以結合該能量體，該結合件係設有一容置空間，該容置空間係供置入並固定該能量體。透過天然礦石材料本身的高頻震盪物理特性，將空氣中的水分子分解，使其變成一個帶正電的氫離子，及一個帶負電的氫氧離子(負離子)。利用該能量體所能產生釋放出來的負離子，藉以對於人體產生一保健的作用。
