Beschreibung
Zusammenfassung:	The utility model discloses a paint spraying control device, which comprises a hot filament spraying gun and a control unit, the control unit comprises a current output regulating circuit, a power feedback processing circuit and a controller, the power feedback processing circuit comprises a power sensor used for detecting the output power of the current output regulating circuit, and the controller is connected with the power sensor. Detection signals of the three-phase rectifier bridge are sequentially processed by the double-operational-amplifier enhancement adjusting circuit and the amplitude-stabilized filter circuit and then sent to the controller, the current output adjusting circuit comprises a triode VT1, and the output end of the controller is connected with a base electrode of the triode VT1. According to the power feedback processing circuit, the power sensor is adopted to sample the output power of the current output adjusting circuit, and power detection is utilized to replace a current detectio
