The utility model provides a spontaneous anion generater, includes a body and an at least air catalyst carrier, the body has inflow entrance, an airflow outlet and an accommodation space at a stretch, accommodation space intercommunication air current entry and airflow outlet, air catalyst carrier sets up in the accommodation space, and air catalyst carrier includes a basal portion, and the basal portion has a plurality of holes, air catalyst carrier is mixed has an ionizationoun catalyst, the ionizationoun catalyst triggers the spontaneous anion that generates of the air current that flows through air catalyst carrier. The utility model discloses a spontaneous anion generater triggers the spontaneous mode that generates the anion of the air current that flows through air catalyst carrier through the ionizationoun catalyst to spread harmful virus and bacterium among the anion destruction of the environment in the air, therefore uses a large amount of manpowers of liquid antibiotic product consumption, the not enough problem with destroying the article outward appearance of effect duration to obtain the solution.一種自發性負離子生成器,包含一本體及至少一空氣觸媒載體。本體具有一氣流入口、一氣流出口及一容置空間。容置空間連通氣流入口與氣流出口。空氣觸媒載體設置於容置空間中。空氣觸媒載體包含一基部。基部具有複數個穿孔。空氣觸媒載體摻有一離子化觸媒。離子化觸媒觸發流過空氣觸媒載體的氣流自發性生成負離子。1‧‧‧自發性負離子生成器100‧‧‧本體110‧‧‧第一側部111‧‧‧第一內壁面120‧‧‧第二側部121‧‧‧第二內壁面130‧‧‧第三側部131‧‧‧第三內壁面140‧‧‧第四側部141‧‧‧第四內壁面200‧‧‧空氣觸媒載體300‧‧‧離子化觸媒400‧‧‧固定件F‧‧‧出風口
