Description

RELATED APPLICATIONS

This invention claims priority, under 35 U.S.C. §120, to the U.S. Provisional Patent Application No. 61/389,376 filed on Oct. 4, 2010, in the name of the same inventor and which application is incorporated by reference herein.

BACKGROUND

This invention relates generally to a air blowing device, and more specifically, to a handheld blowing device which may be used to send a stream of air to clean different surface areas.

Presently, there are many different ways to clean dusty/dirty surfaces. For example, individuals may use feather dusters, dust cloths, vacuum cleaners and the like. Recently, some individuals have been using microfiber cloths as a way to clean dusty/dirty surfaces. The problem with all of the above devices is that all of the above devices are unable to get into and clean small tight defined areas. For example, the above devices are unable to clean the area between and under the keys of a keyboard and the like.

To clean keyboards and other electronic devices, many individuals have been using cans of compressed air. The cans generally have a straw nozzle which may allow one to direct the compressed air stored in the can to clean a dirty surface. Though using compressed air for electronics cleans the computer and electronics quickly and easily, it does have several disadvantages. Using this gas may leave a good amount of moisture inside the computer that may eventually corrode the delicate components. It may also lead to water build up in the circuit boards in the electronic equipments. Furthermore, using this compressed gas at high pressure for cleaning can damage the circuits of the electronic device.

In addition, using compress air for electronic devices also has some environmental concerns. Most of these cans use a GHG, that is greenhouse gas, as the propellant, referred to as HFC. They indirectly contribute to the stratospheric ozone layer depletion and are thus becoming a cause for global warming.

Therefore, it would be desirable to provide a device and method that overcomes the above problems.
