Automatic paint spraying device adopting dual power supply and electrostatic spinning technology

The invention discloses an automatic paint spraying device adopting dual power supply and the electrostatic spinning technology. According to the electrostatic spinning principle, a specially-made electrostatic paint solution in a solution storage cavity (16) is driven by a direct current motor (5) to be injected into a high-voltage grapheme pinhole electrode (15) connected with a high-voltage electrode (14), and when objects to be treated get close to a grounded metal nozzle (12), uniform and fine paint mists are sprayed to the surfaces of the objects to be treated from the grounded metal nozzle (12). In addition, for improving the safety and the practicality, a dual power supply system composed of a commercial power port (2) and a rechargeable battery (4) is arranged. Compared with a traditional paint spraying device, the automatic paint spraying device has the advantages of being small in size, light in weight, convenient to carry, economical and practical, and mist spraying is uniform.
