Abstract
Abstract An air conditioning unit for use in the cooling of persons includes a fan secured below the person's neck. A moistened foam necklace may be wrapped around the neck or a moistened foam pad otherwise positioned between the fan and the neck of the user. The fan of the air conditioning unit includes a frame, an electric motor mounted on the frame, a fan blade operably connected with the motor and rotatable by the motor for moving air, a battery or other power source operably connected with the motor for actuation thereof, and a switch operably connected between the battery or power source and the motor for controlling the actuation of the motor. Furthermore, the air conditioning unit includes a flexible element attached to the frame, the flexible element being constructed and arranged to be worn around the user's neck so that air generated by the moving fan blade moves against the neck area after being evaporatively cooled by the foam necklace or pad.
