[0001] The utility model relates to the technical field of smoke extraction devices, in particular to a smoke extraction mechanism and a laser processing device with the smoke extraction mechanism. Background Art

[0002] In the laser processing technology, a large amount of smoke is generated due to the partial burning or melting of the material. This smoke will pollute the components and laser optical path of the laser, thereby affecting the performance of the laser. In particular, the pollution of the reflector and focusing mirror of the laser external optical path will seriously affect the performance of the laser and reduce the stability of the laser. In addition, the large amount of smoke pollutes the environment and is not good for the health of laser operators. Usually, laser cutting machines use a smoke extraction device to extract the smoke generated during the processing; however, the current smoke extraction end of the smoke extraction device is mostly aimed at the position of the workpiece to be processed, which causes the workpiece position to shift during the extraction, affecting the processing accuracy.
