Abstract
Official abstract text for this publication.
An air blower includes a motor; a fan connected to an output shaft of the motor and rotatively driven by the motor; and a fan nut fixing the fan onto the output shaft of the motor, a diffusive substance is kept in the fan nut provided on the output shaft of the motor, and an ion generating unit is attached to a motor body concentrically with the output shaft. Therefore, the diffusive substance, positive ions and negative ions may be diffused without interrupting blowing and without harmfully affecting the air blowing function. Since the diffusive substance and the ion generating unit are provided inside a fan guard, an infant or the like may be prevented from touching them, and thus, the safety may be secured.
First claim
Opening claim text (preview).
The invention claimed is: 1. An air blower comprising: a motor; a fan rotatively driven by the motor; a fan guard surrounding and protecting the fan; and an ion generating unit generating positive ions and negative ions; wherein the ion generating unit is provided inside the fan guard between the motor and the fan. 2. The air blower according to claim 1 , wherein the ion generating unit also works as a fixing ring for fixing the fan guard onto the m…
