DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The figures show a preferred embodiment of a device constructed in accordance with the present invention for dissipating hot air accumulated in a laser cutter. Although the laser cutter is of a conventional type having a cutting table and a waste collector 31 situated under the cutting table, the waste collector 31 here is provided with a side window (not shown in figures).
Referring to FIGS. 1 and 2, the inventive device includes a wind box 1 having an open back (not shown) and a plurality of openings 11 defined in a wall thereof, preferred in a wall opposed to the open back. The wind box 1 is adapted to be attached to the waste collector 31 in such a manner that the open back is positioned at and aligned with the side window of the collected 31, as shown in FIGS. 3 and 4.
Arranged on the wind box 1 at the openings 11 is a plurality of electric fans 2 for producing air current. Preferably, a screen plate 4 covers the open back of the wind box 1, and more preferably, the screen plate 4 has a plurality of hexagonal meshes 41 defined therein.
Referring still to FIGS. 1 and 2 and additionally to FIGS. 3 and 4, the inventive device can be assembled by fastening the screen plate 4 to the open back of the wind box 1. Then, the electric fans 2 are arranged on the wind box 1 at the openings 11 after the box 1 is attached to the waste collector 31. Thus, air current produced by the electric fans 2 may rush into the waste collector 31 through the wind box 1 and dissipate hot air and scraps fallen into the waste collector under the cutting table during the cutting process.
From the foregoing, it is apparent that the present invention is advantageous in that:
- 1. With the inventive device, hot air and scraps fallen into the waste collector under the cutting table during the cutting process can be dissipated quickly and efficiently; and
- 2. In the inventive device, the screen plate can protect the electric fans from being accidentally shot by the laser beam.
Although embodiments together with structures of the present invention have been described in detail, many modifications and variations may be made from the teachings disclosed hereinabove. Therefore, it should be understood by those skilled in the art that any modification and variation equivalent to the spirit of the present invention be regarded to fall into the scope covered by the appended claims.
