[0002] Laser cutting machines use invisible light beams to replace traditional mechanical knives. They have the characteristics of high precision, fast cutting, smooth incisions, and low processing costs. They are widely used in the fields of automobiles, machinery, electricity, hardware, and electrical appliances.

[0003] Most of the common laser cutting machines on the market are similar in overall structure. They are mainly based on a square support frame. The gantry system driven by a servo motor controls the displacement of the cutting head to cut the desired shape on the surface of the material. There are some functional deficiencies in actual use and there is room for improvement. For example, although the current laser cutting head is equipped with a high-pressure gas blowhole at the laser emission port during the cutting process to prevent flying debris from damaging the lamp head at the emission port, other places on the outside of the cutting head will still be sputtered by vaporized hot-melt metal. These metal chips adhere to the surface of the cutting head after cooling. The laser cutting head needs to be removed for cleaning. The overall operation is more troublesome and does not have the function of facilitating the cleaning of the cutting head.

[0004] Now, a new type of laser cutting machine with convenient cleaning of the cutting head is proposed to solve the above problems. Utility Model Content
