Description
- The present invention relates to air blowers, and more particularly, to an air blower which receives power via a Universal Serial Bus (USB) interface.
- 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 keys of typewriters and computer keyboards and from fragile or irregularly-shaped objects, such as dried flower arrangements and artificial plants. These air blowers for cleaning dust are typically powered by one or more batteries in order to avoid the need for a power cord and electrical outlet. However, the batteries will be consumed and must be replaced by other good batteries after a period of time, which is inconvenient, and may pollute the environment because of the used batteries.
- What is desired, therefore, is to provide an air blower which can conveniently clean electronic devices.
- An exemplary Universal Serial Bus (USB) air blower includes a housing, a direct current (DC) fan, a discharge element, and a USB interface. The discharge element is arranged on a front end of the housing. The DC fan is installed in the housing. The USB interface is electrically coupled to the DC fan. The discharge element includes a discharge aperture to discharge air generated by the DC fan.
- Other advantages and novel features will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings, in which:
-
FIG. 1 is an isometric, exploded view of a USB air blower in accordance with a preferred embodiment of the present invention; -
FIG. 2 is an assembled view ofFIG. 1 ; and -
FIG. 3 is a circuit diagram ofFIG. 1 . - Referring to
FIG. 1 , a Universal Serial Bus (USB)air blower 10 in accordance with a preferred embodiment of the present invention is shown. TheUSB air blower 10 includes an elongate box-shaped housing 12, a funneleddischarge element 14 having aslender discharge end 142, a direct current (DC)fan 16, and aUSB interface 18. Theslender discharge end 142 has a discharge aperture formed at a front end thereof and anelectrostatic brush 148 around the discharge aperture. Thehousing 12 and thedischarge element 14 may be manufactured of any appropriate material, preferably a lightweight, durable material, such as high-impact plastic. A specification of theDC fan 16 can be chosen according to need, such as 40×40×28 mm, and thefan 16 includes a pair of alignedmounting holes 164 defined in each of four corners thereof in this embodiment. - A
concave portion 124 is defined in an inner surface of a front end of thehousing 12. Aflange 146 protrudes from four sides of a rear end of thedischarge element 14 corresponding to theconcave portion 124. Two threaded holes (not shown) are defined in thehousing 12 corresponding to themounting holes 164 of theDC fan 16. TheUSB interface 18 is connected to a rear end of thehousing 12 via apower cable 19. - In this embodiment, a
switch 122 is disposed on a top of thehousing 12 for turning thefan 16 on and off. Alight 144 such as a light-emitting diode (LED) is mounted on a top of thedischarge element 14. - Referring also to
FIG. 2 , in assembly, thefan 16 is installed in thehousing 12 by known means such as twoscrews 166 extending through two corresponding throughholes 164 of thefan 16 and into corresponding threaded holes of thehousing 12. Thedischarge element 14 is connected to thehousing 12 with theflange 146 of thedischarge element 14 engaging with theconcave portion 124 of thehousing 12. Thedischarge element 14 and thehousing 12 also can be integrally formed together, and thefan 16 is installed in thehousing 12 from the rear end thereof. - Referring also to
FIG. 3 , a circuit diagram of theUSB air blower 10 is shown. Thefan 16 includes aDC motor 162 therein. One terminal of themotor 162 is electrically coupled to a power terminal VCC of theUSB interface 18 via theswitch 122, and the other terminal of themotor 162 is electrically coupled to a ground terminal GND of theUSB interface 18. Thelight 144 is connected to themotor 162 in parallel. - When using the
USB air blower 10 to clean an electronic device such as a computer keyboard (not shown), theUSB interface 18 of theUSB air blower 10 is plugged into a USB port of the computer, then theswitch 122 of theUSB air blower 10 is depressed. Thefan 16 works and produces airflow from the discharge aperture of thedischarge end 142. At the same time, thelight 18 lights up and facilitates seeing where to direct thefan 16 to clean the keyboard. Further, theelectrostatic brush 148 of thedischarge element 14 can clean electrostatic dust on the keyboard. Thus, theUSB air blower 10 conveniently and easily cleans the electronic device. - It is to be understood, however, that even though numerous characteristics and advantages of the preferred embodiments have been set forth in the foregoing description, together with details of the structures and functions of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, equivalent material and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
