PROBLEM TO BE SOLVED: To provide an improved scent pad that is optimized for a humidifier and prevents the humidifier from being damaged, and a mechanism for housing the scent pad.SOLUTION: A mechanism is preferably a part of a humidifier or similar device and is positioned adjacently to a heated surface of the humidifier. The mechanism preferably includes a cover, a keyed portion and a rib portion which allows a scent pad to fit properly and prevents other shaped pads from being inserted into or used in the housing mechanism. According to one embodiment of the present invention, the scent pad 100 includes an upper straight edge 105, side edges 106 and 107, two lower beveled edges 110 and 115, and a lower straight edge 112 situated between the lower beveled edges. The beveled edges are arranged at such an angle that the beveled edges intersect both the lower straight edge and a side edge.【課題】加湿器の最適な性能とし、さらに加湿器の損傷を防ぐ改良型芳香パッド及びそれを収容する機構を提供する。【解決手段】機構は、好ましくは加湿器又は同様の装置の一部であり、加熱表面に隣接して配置される。機構は、好ましくはカバーと、有鍵部と、芳香部材を適切に適合させるとともに、他の形状のパッドが収容機構に挿入されあるいは使用されることを防止し、運転を最適化するリブ部とを備える。一実施形態においては、芳香パッド１００は、上部直線縁１０５、側縁１０６、１０７、２つの下部傾斜縁１１０，１１５、及び傾斜縁間にある下部直線縁１１２を備える。傾斜縁は下部直線縁及び側縁の両方を横切る角度で配置される。【選択図】図１
