Detailed Description

Reference will now be made in detail to embodiments of the present utility model, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

Referring to figures 1-5 for an embodiment of a dual exhaust apparatus for a laser engraving machine in accordance with the present utility model,

comprises an engraving machine body 1; a workbench 2 and a smoke exhausting device are arranged in the engraving machine body 1; the smoke exhausting device is arranged at one side of the workbench 2; the smoke exhausting device comprises a first smoke inlet arranged above the workbench 2, a second smoke inlet arranged below the workbench 2 and a smoke exhausting hole; the first smoke inlet is formed by a first smoke drawing groove 5 at the front end of the first cigarette case 4, and the second smoke inlet is formed by a second smoke drawing groove 7 at the front end of the second cigarette case 6; the first cigarette case 4 and the second cigarette case 6 are communicated to form an integrated case, and a smoke extraction pipe 8 is arranged at the rear end of the integrated case.
