It is a kind of to divide day with fog with what antrodia incubator, its longitudinal pipe supplies the fog containing nutritional ingredient to enter Hou by entrance, it is sprayed through vertical passage by the first spout, and enters the interconnection of transverse pipe and can be sprayed by the second spout, plural longitudinal ring has perforation, with the rotation of each longitudinal ring, selection allows its perforation to be aligned with the first spout of corresponding position and communicates or be staggered and be not communicated with, and to control the opening and closing of aforementioned first spout, thereby constitutes this creation.一種用於樟芝培養箱的分霧器，其縱向管供含有營養成分之霧氣由入口進入後，經縱向通道而由第一噴口噴出，且進入橫向管之橫向通道而可由第二噴口噴出，複數縱向環具有穿孔，以各縱向環轉動而選擇讓其穿孔與對應位置的第一噴口對準而相通或錯開而不相通，以控制前述第一噴口之啟閉，藉此構成本創作。
