PROBLEM TO BE SOLVED: To provide ab air cleaning tool which can stably generate chlorine dioxide and can be reduced in size.SOLUTION: An air cleaning tool 10 comprises a chlorine dioxide generating agent which reacts with carbon dioxide to generate chlorine dioxide, a plurality of storage chambers capable of storing the chlorine dioxide generating agent and a case 1 having discharge holes 113 and 123 for discharging chlorine dioxide generated by the chlorine dioxide generating agent. The plurality of storage chambers are communicated with each other directly or indirectly so that the chlorine dioxide generating agent may be moved between the respective storage chambers.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2016,JPO&INPIT【課題】二酸化塩素を安定して発生させることができ、小型化が可能な空気清浄用具を提供する。【解決手段】空気清浄用具10は、二酸化炭素と反応して二酸化塩素を発生させる二酸化塩素発生剤と、二酸化塩素発生剤を収容可能な複数の収容室、及び二酸化塩素発生剤が発生させる二酸化塩素を放出する放出孔113,123を有するケース1と、を備える。複数の収容室は、二酸化塩素発生剤が各収容室間を移動できるよう、直接又は間接的に連通している。【選択図】図2
