[0046] The first accommodating groove 10a is opened in the heat sink 10 and is located inside the heat sink 10, so that the first accommodating groove 10a serves as the internal space of the heat sink 10, and the second accommodating groove 10b is recessed in the outer wall of the heat sink 10; the second accommodating groove 10b and the first accommodating groove 10a are spaced apart along the width direction of the heat sink 10, so that the air pump 30 located in the first accommodating groove 10a and the laser 20 located in the second accommodating groove 10b are integrated into the same heat sink 10, thereby facilitating the air pump 30 and the laser 20 to share the same heat sink 10, thereby achieving full utilization of the space of the heat sink 10, improving the integration of the laser assembly 100, and avoiding the air pump 30 being externally placed on the heat sink 10.

[0047] The air nozzle 40 is provided with a first flow channel 41 and a second flow channel 42; the first flow channel 41 is used for the laser output through the output end of the laser 20 to pass through, so that the laser at the output end of the laser 20 is transmitted to the workpiece to be processed through the first flow channel 41; the second flow channel 42 is arranged on the peripheral side of the first flow channel 41, the second flow channel 42 is connected to the first flow channel 41, and is connected to the output end of the air pump 30, so that the gas output from the output end of the air pump 30 flows to the workpiece to be processed through the second flow channel 42 and the first flow channel 41, so that the gas output from the output end of the air pump 30 is convenient for cleaning the internal space of the air nozzle 40, and cooperates with the laser output from the output end of the laser 20 to act on the workpiece to be processed, thereby improving the processing effect of the laser component 100 on the workpiece to be processed.
