[0002] The rotary atomization spraying system is widely used in surface treatment processes of automobile manufacturing, electronic equipment, aerospace, hardware products and other industries. Its principle is to use the centrifugal force generated by the high-speed rotating disc or wheel to throw the liquid out to form droplets. The rotation speed of the spraying cup is usually greater than 20000 rpm, which can realize linear, laminar and multi-piece turbine atomization.

[0003] After searching, the patent with the publication number CN115350827A discloses a rotary atomization type coating device. The rotary atomization type coating device is provided with a bell-shaped cup on the rotating drive shaft. The side surface part of the bell-shaped cup is formed in parallel with the rotating drive shaft. A first groove part, a second groove part and a third groove part are provided on the inner surface of the side surface part, which are recessed towards the outer surface of the side surface part.
