Ion detecting apparatus and ion generating apparatus

Abstract

An air blower including a motor 2 having output shafts 21, 21 on both sides in the axial direction and two impellers 3, 3 mounted on the respective output shafts 21, 21, and two ducts 5, 5 that individually allow passage of the air blown out by rotation of each of the impellers 3, 3 in the same direction and discharge the air to the outside are included. At a part or the whole of each of the ducts 5, 5, a laminar flow section that makes the flowing air laminar flow. An ion generating section is arranged at each laminar flow section so that ions generated by the ion generating section can effectively be included in the air, increasing the ion concentration of ions discharged in a room together with the air.
