Abstract
A cord retainer and cord wrap system for use with a portable (e.g., handheld) electric blower, and a blower incorporating the same. The system may allow for storage of the cord onboard the blower when the latter is not in use. Embodiments of the invention may utilize a portion of the blower housing to form one winding surface for the cord. A second winding surface may be provided by a cord retainer that may be secured in place along the extension tube of the blower, e.g., via interference fit. Other embodiments may include two or more nozzles that may be selectively inserted into the extension tube to permit selective tuning of blower performance.
