[0046] The bottom outer side of the boss portion 115 is provided with a notch 1151 to facilitate the removal of the air passage plate 11.

[0047] The working principle of this invention is as follows: Compressed air is input through the input interface and distributed within the air circuit board 11 to the sector control proportional valve 12, atomization control proportional valve 13, flow control proportional valve 14, and solenoid valve 15. The sector control proportional valve 12, atomization control proportional valve 13, and flow control proportional valve 14 are controlled by a PLC to precisely control the sector shape, atomization, flow rate, and air volume and pressure output of the spray gun. The solenoid valve 15 is controlled by the PLC to open and close the spray gun.
