It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The utility model provides a laser cutting machine in one embodiment, as shown in fig. 1, comprising a laser head 100, a smoking bracket 200, an air outlet 300 and an air suction inlet 400; the smoking bracket 200 comprises a sleeve 210, a left bracket 220 and a right bracket 230, wherein the left bracket 220 and the right bracket 230 are symmetrically arranged at two sides of the sleeve 210; the smoking bracket 200 is sleeved at the working end of the laser head 100 through the sleeve 210, the air outlet 300 is arranged on the left bracket 220 and faces to the top end of the working end of the laser head 100, and the air suction inlet 400 is arranged on the right bracket 230 and faces to the air outlet 300. As will be appreciated by those skilled in the relevant art, the air outlet 300 and the air inlet 400 are respectively connected to a pipeline capable of conveying air flow and a fan for driving the air flow to move, the air outlet 300 is connected to a blower through a pipeline, and the air inlet 400 is connected to an exhaust fan through a pipeline. When the high-energy laser in the vertical direction is used for laser cutting, the generated smoke can be rapidly taken away by transverse airflow, and the smoke removing efficiency is high.
