Description
- This application is a continuation of International Application No. PCT/US03/023399, filed Jul. 25, 2003, entitled “Portable Hand-Held Battery-Operated Dust Blower.” That application claimed the benefit of U.S. Provisional Patent Application Ser. No. 60/399,099, filed Jul. 26, 2002, under the same title.
- 1. Field of the Invention
- This invention relates to hand-held air blowers, and more particularly, to a hand-held, battery-operated air blower that achieves superior airflow through use of a centrifugal fan mounted transversely toward the front of the blower.
- 2. Description of the Prior Art
- Air blowers in various forms are available for numerous uses, such as drying hair or other objects, blowing fallen leaves, and blowing air into a fireplace or charcoal grill to accelerate combustion. Another application for air blowers is removal of dust from hard-to-reach places, such as between the keys of typewriters and computer keyboards and from fragile or irregularly-shaped objects, such as dried flower arrangements and artificial plants. For this application, the blower will be most useful if it is small enough to be held in one hand and powered by one or more batteries in order to avoid the need for a power cord and electrical outlet.
- In order to extend battery life in such an application and avoid the need for an excessively large power supply, it is important that the blower mechanism be as efficient as possible at converting electrical energy to air flow. While several types of hand-held, battery-operated blowers are presently available, they typically employ either an axial-type fan or a centrifugal fan mounted coaxially with the longitudinal axis of the blower housing.
- For example, U.S. Pat. No. 4,734,017 discloses a blower employing an axial-type fan, similar to a propeller, which draws air into the fan inlet and expels it axially.
- Greater air pressure can typically be achieved through use of a centrifugal fan, such as that employed in the blower disclosed by U.S. Pat. No. 6,092,260, which draws air into the inlet and forces it out of the fan at a right angle radially. However, the blower of U.S. Pat. No. 6,092,260 has the centrifugal fan mounted coaxially in the blower housing, causing the air stream to be directed against the inner walls of the blower housing rather than directly toward the discharge aperture. This position may increase turbulence within the housing, diminishing the efficiency of blower operation. This problem may be exacerbated by placement of the fan toward the rear of the blower housing in the device of U.S. Pat. No. 6,092,260 because the fan must force air past the blower motor and batteries before it reaches the discharge aperture.
- Thus, there remains a need for a hand-held, battery-operated blower that takes full advantage of the greater efficiency of a centrifugal fan by having the centrifugal fan mounted toward the front of the blower housing transverse to the longitudinal axis of the blower housing so that air flow generated by the fan reaches the discharge aperture with minimal obstruction.
- Accordingly, it is an object of the present invention to provide a hand-held, battery-operated blower that efficiently produces a stream of air through a discharge aperture from a transverse-mounted centrifugal fan. Specifically, the present invention provides a hand-held, battery-operated blower comprising: a housing having a handle portion and a discharge end with an air inlet on one side of the discharge end and a discharge aperture at the tip of the discharge end; a compartment within the handle portion for containing batteries; a motor disposed within the housing between the battery compartment and the discharge aperture transverse to the longitudinal axis of the housing, said motor being electrically connected to the battery compartment; a centrifugal fan mounted on the motor within the housing and adjacent to the air inlet; and means for controlling the supply of electricity from the power source to the motor in order to turn the blower on and off.
