ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an electric power supply device, and more particularly to an electric power supply device having a fan device that may be detached and that may be easily fixed or replaced with the other ones.
2. Description of the Prior Art
Typical electric power supply devices comprise one or more plugs and sockets provided therein and coupled to or between various electrical facilities, and/or comprise an electric circuit provided there in for stabilizing the electric power and for providing a stabilized electric power to the electrical facilities. The electric power supply devices may generate heat during operation, such that one or more fan devices are required to be provided and attached to each of the electric power supply devices for dissipating the heat that may be generated by the electric power supply device. However, the fan devices are fixed in the electric power supply device and may not be detached or disengaged from the electric power supply device, such that the fan device may not be easily fixed or replaced with the other one when the fan device is damaged or the like.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional electric power supply devices.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide an electric power supply device including a fan device that may be detached and that may be easily fixed or replaced with the other ones.
In accordance with one aspect of the invention, there is provided an electric power supply device comprising a housing including a front portion and an upper portion, a cover secured to the upper portion of the housing, a casing including at least one opening formed therein and including a front portion, at least one fan member secured to the casing and aligned with the opening of the casing, at least one net secured to the front portion of the casing for blocking the opening of the casing, and means for detachably securing the casing and thus the fan member to the cover and the housing. One or more electric power supply devices may be received in a receptacle and coupled between the electrical facilities.
The housing includes two side walls each having an upper front portion and an upper rear portion, the cover includes two flanges secured to the upper front portions of the side walls and includes two ears secured to the upper rear portions of the housing. The side walls each includes a front portion, the casing includes two side panels secured to the front portions of the side walls respectively.
The cover includes at least one front ear provided thereon, and at least one fastener is engaged with the casing and the front ear of the cover for detachably securing the casing and thus the fan member to the cover and the housing.
The fan member includes at least one cavity formed therein, the detachably securing means includes at least one lock nut received in the cavity of the fan member, and at least one fastener engaged through the net and the casing and the fan member and threaded with the lock nut for detachably securing the casing and thus the fan member to the cover and the housing.
The casing includes an extension extended therefrom, the electric power supply device further includes a plate, and means for securing the plate to the extension of the casing. The plate includes a switch and/or a socket provided thereon.
A handle is further pivotally secured to the casing. The detachably securing means includes two fasteners secured to the casing, the handle is pivotally secured to the fasteners with pivot pins.
Further objectives and advantages of the present invention will become apparent from a careful reading of a detailed description provided hereinbelow, with appropriate reference to accompanying drawings.
