PROBLEM TO BE SOLVED: To provide a portable air cleaner which can easily and quickly cope with both electricity from a 100 V receptacle and electricity from an on-vehicle battery, and dispenses with a connection code for connecting to a 100 V receptacle or a cigar lighter socket.SOLUTION: A portable air cleaner includes: an air cleaner body part 1 which incorporates a cleaning component generator and a receptacle plug part 2 which has an insertion pin 21 insertable into and removable from an existing 100 V receptacle. A body casing of the air cleaner body part 1 is partially or entirely made of a resin containing germanium. A cylindrical insertion shaft part 3 is projected from the air cleaner body part 1, and a cylindrical insertion hole part 23, into which the insertion shaft part 3 is inserted, is recessed in the receptacle plug part 2, whereby the air cleaner body part 1 and the receptacle plug part 2 are provided so as to be freely combined with and separated from each other. The insertion shaft part 3 is provided so as to be electrically connectable by being inserted into a cigar lighter socket 6 of a vehicle, so that the air cleaner body part 1 can be operated by an on-vehicle battery.COPYRIGHT: (C)2014,JPO&INPIT【課題】100V用コンセントからの電気と、車載バッテリーからの電気の両方に、容易かつ迅速に対応可能で、100V用コンセントやシガーライタソケットとつなぐための接続コードが不要な携帯用空気清浄機を提供する。【解決手段】清浄成分発生器が内蔵された空気清浄機本体部1と、既設の100V用コンセントに抜き差し可能な差込ピン21を有するコンセントプラグ部2と、を備えた携帯用空気清浄機であって、空気清浄機本体部1の本体ケーシングの全体又は一部が、ゲルマニウムが含有された樹脂製であり、空気清浄機本体部1から円柱状の差込軸部3を突設し、コンセントプラグ部2に差込軸部3が差し込まれる円形状の差込孔部23を凹設して、空気清浄機本体部とコンセントプラグ部とを合体・分離自在に設け、差込軸部3を、車両のシガーライタソケット6に差込んで電気的に接続可能に設けて、空気清浄機本体部1を車載バッテリーにて作動可能とした。【選択図】図6
