[0002] Laser cladding technology is a widely used method for additive manufacturing, surface strengthening and repair of the inner surface of parts. Currently, the common methods are coaxial powder feeding inner wall laser cladding method and lateral powder feeding inner wall laser cladding method. The powder utilization rate of the former is generally 50%-80%, and the powder utilization rate of the latter is generally 80%-95%. Laser cladding technology can also improve the hardness, wear resistance, corrosion resistance and thermal tolerance of the material. At the same time, it can also repair, mend or repair the surface defects of parts. By adding cladding material to the surface of the workpiece to be clad, and using a high-energy density laser beam to melt the cladding material together with the thin layer on the surface of the workpiece to be clad, a cladding layer is formed on the workpiece to be clad that is metallurgically bonded to the thin layer on the surface of the workpiece to be clad.

[0003] At present, laser cladding technology tends to be mature, but it also has some defects. One of them is that when using a laser nozzle for processing, powder impurities often splash and adhere to the surface of the laser cladding nozzle, and when large particles of impurities are found by the naked eye, the machine needs to be stopped, and then a cleaning tool (such as a brush) is used to remove the powder impurities from the surface of the laser cladding nozzle, which affects the laser cladding efficiency and causes great wear to the laser cladding nozzle, greatly shortening the service life of the laser cladding nozzle. Therefore, it is urgent to design a self-cleaning laser cladding nozzle to solve the above problems. Utility Model Content
