[0005] Although the above patent achieves the cooperation between the suction fan and the filter box, so that the toxic gas and odorous gas generated by the cutting of the laser cutting machine body are sucked in through the connecting pipe, and then filtered through the filter box, and then the purified gas is discharged to the outside through the outlet pipe, thereby reducing the harm of toxic gas and odorous gas to the human body, thereby improving the safety of the operators; however, the device does not allow for the cleaning of metal debris accumulated on the surface of the workbench, which easily causes the debris to accumulate on the surface of the workbench, thereby affecting the normal use of the equipment.
