Abstract
A portable rechargeable battery-operated slender tubular blower for removing relatively light debris from hard surfaces such as sidewalks, driveways, decks or workbench surfaces. The blower uses an axial flow blower fan arranged for noise minimization and energy efficient operation. Blower tube inlet and outlet portions are arranged debris removal effectiveness by optimizing airflow volume and velocity parameters.
Claims20
A hand-held portable, electrically driven blower adapted to be usable by users of varying heights, comprising:
- an elongated tubular housing defining a longitudinal axis;
- an electrical drive motor mounted to said housing and having a drive shaft;
- fan means coupled to the drive shaft of said motor and having a plurality of fan blades for moving air through said tubular housing;
- an elongated handle connected to said tubular housing and adapted to be grasped by the hand of the user at various positions along the length of said handle so that the tubular housing of the blower is suspended from the handle when in use;
- and
- switch means including an electrical switch electrically connected to said drive motor for controlling the application of electrical energy to said drive motor and elongated actuator means connected to said electrical switch for controlling the position of said switch, said elongated actuator means being located in said handle and actuable by the hand of the user when grasping said handle at any of said various positions on said handle.
A hand-held portable, electrically driven blower adapted to be usable by users of varying heights for blowing debris from sidewalks, driveways, decks, and other such surfaces, comprising:
- an elongated tubular housing defining a longitudinal axis and having sufficient length to extend proximate to the surface on which a user is standing when holding the blower;
- an electrical drive motor mounted to said housing and having a drive shaft;
- fan means coupled to the drive shaft of said motor and having a plurality of fan blades for moving air through said tubular housing;
- an elongated handle connected to said tubular housing and adapted to be grasped by the hand of the user at various positions along the length of said handle so that in the normal operating position of the blower the tubular housing of the blower is suspended from the handle when in use;
- and
- switch means including an electrical switch electrically connected to said drive motor for controlling the application of electrical energy to said drive motor and elongated actuator means connected to said electrical switch for controlling the position of said switch, said elongated actuator means being located in said handle and actuable by the hand of the user when grasping said handle at any of said various positions on said handle.
A hand-held portable, electrically driven blower adapted to be usable by users of varying heights for blowing debris from sidewalks, driveways, decks, and other such surfaces, comprising:
- an elongated tubular housing defining a longitudinal axis;
- an inlet portion connected to one end of said tubular housing and an outlet portion connected to the other end of said tubular housing;
- an electrical drive motor mounted within said tubular housing intermediate said inlet and outlet portions and having a drive shaft substantially aligned with said longitudinal axis;
- fan means coupled to the drive shaft of said motor and having a plurality of fan blades for moving air through said tubular housing from said inlet portion to said outlet portion;
- an elongated handle connected to said tubular housing and adapted to be grasped by the hand of the user at various positions along the length of said handle so that in the normal operating position of the blower the tubular housing of the blower is suspended from the handle when in use;
- said tubular housing having sufficient length so that said outlet portion is positioned proximate to the surface on which the user is standing when holding the blower by said handle;
- and
- switch means including an electrical switch electrically connected to said drive motor controlling the application of electrical energy to said drive motor and elongated actuator means connected to said electrical switch for controlling the position of said switch, said elongated actuator means being located in said handle and actuable by the hand of the user when grasping said handle at any of said various positions on said handle.
