Detachable fan apparatus for quick maintenance

Abstract

A detachable fan apparatus for quick maintenance installable in a computer casing and swappable for maintenance without turning off the fan includes a frame, a stopping plate on the frame, at least one fan at the fan, a gap between the fan and the frame for installing a filter, an axial rod at an end of the frame and pivotally connected with a pivotal of the computer casing, and a stopping pillar near the opening. When an end without the axial rod is secured with the computer casing, the frame can be fixed onto the computer casing. For the change of a filter, a secured end of the frame is separated from the computer casing, and the frame is turned outward and inclined to a predetermined angle until the stopping plate is pressed onto the stopping pillar by the pivotal hole and axial rod for the change of a filter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 2 and 3 for a detachable fan apparatus for quick maintenance in accordance with the present invention, the fan is installed onto a computer casing 10, and a surface of the computer casing 10a has at least one opening 11 (wherein this embodiment has three openings 11, but the number of openings can vary according to actual requirements), and both sides of the opening 11 separately have a protruding ear 12, and each protruding ear 12 is disposed corresponding to each pivotal hole 121, and the pivotal holes 121 are inclined to a predetermined angle (which is 45 degrees in this embodiment), and both sides of the opening 11 separately include a protruding plate 13, and each protruding plate 13 has a locking hole 131, and the protruding ear 12 and the protruding plate 13 are disposed proximate to distal edges, and the computer casing 10 has a stopping pillar 14 proximate to the opening 11.

Further, a frame 20 is pivotally connected to the opening 11, and the frame 20 has a rear panel 21, and the rear panel 21 has a plurality of meshes 201, and the rear panel 21 includes a partition 22 with meshes 221 thereon, such that a gap is maintained between the partition 22 and the rear panel 21 for installing a filter 23, and a fan 30 is secured onto the partition 22 and has an electric plug 31 connected to an electric circuit and a power supply in the computer casing 10. Both sides of the rear panel 21 separately have a locking hole 211 for securing a screw rod 24, and the screw rod 24 can be passed through the locking hole 211 and secured onto the locking hole 131. Further, both sides of the rear panel 21 separately have an inwardly curved bent plate 212, and each bent plate 212 has a protruding axial rod 213, and the axial rod 213 is embedded into the pivotal hole 121, such that the rear panel 21 can be pivotally connected to the opening 11. The rear panel 21 has a stopping plate 214, such that if the stopping plate 214 at the rear panel 21 is turned outward from the opening 11, the stopping plate 214 will press on the stopping pillar 14 to erect the rear panel 21 at its position (as shown in FIG. 6).

When the fan apparatus is used as shown in FIGS. 4 to 6, the axial rods 213 are embedded into the pivotal holes 121 respectively, such that the rear panel 21 is pivotally connected to the opening 11 to seal the opening 11 (as shown in FIG. 5), and the fan 30 can be electrically connected to the electric circuit and a power supply in the computer casing 10. On the other hand, if it is necessary to change a filter 23, a user simply loosens the screw rod 24 to separate the screw rod 24 from the locking hole 131, and turns the frame 20 naturally outward to a specific angle by the inclined pivotal hole 121 to allow the user to conveniently remove and change the filter 23. Such arrangement can achieve the effect of a convenient use without interrupting the operation of the fan or removing the whole frame.

While the invention has been described by way of example and in terms of a preferred embodiment, it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements and procedures, and the scope of the appended claims therefore should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements and procedures.

In summation, the present invention enhances the performance than the conventional structure and further complies with the patent application requirements and is duly filed for the patent application.

Claims

1. A detachable fan apparatus for quick maintenance, installed to a computer casing and comprising: a computer casing, having at least one opening disposed on a surface of said computer casing, a protruding ear disposed separately on both sides of said opening, a pivotal hole disposed separately at said protruding ears, and a stopping pillar disposed at a position proximate to said opening of said computer casing;a frame, pivotally coupled to said opening of said computer casing, and having a rear panel and a partition fixed onto said rear panel, a gap maintained between said partition and said rear panel, and an axial rod disposed on said rear panel, such that said axial rod is embedded into said pivotal hole, and said frame further includes a stopping plate disposed corresponding to said stopping pillar;a filter, included between said rear panel and said partition; anda fan, fixed onto a surface of said partition;such that when an end without said axial rod of said frame is secured with said computer casing, said frame can be fixed onto a surface of said computer casing, and when it is necessary to change said filter, a secured end of said frame is separately from said computer casing, and said frame is turned outward until said stopping plate is pressed onto said stopping pillar by means of said pivotal hole and said axial rod, so that said frame is inclined to a predetermined angle for the change of a filter, so as to achieve the effect of a convenient use without the need of interrupting the operation of said fan or removing said frame.

2. The detachable fan apparatus for quick maintenance of claim 1, wherein said pivotal hole is inclined to a predetermined angle.

3. The detachable fan apparatus for quick maintenance of claim 1, wherein said fan is coupled to a power supply in said computer casing directly by an electric circuit.
