<p>A solar-powered ventilated hat with light-chasing function comprising an inner mesh hat 1 and an outer hat body 2 pivotally connected to the inner hat body, the outer hat body comprising a fan 23 and a servomotor (24, fig.3) also pivotally connected to the top edge of the inner hat body, and a light-detecting part 26, a solar panel 27 and a control circuit 28 located on the brim of the outer hat body. The solar panel is electrically connected to the fan and the servomotor. The light detecting part detects sunlight and drives the servomotor to rotate the outer hat body so that the solar panel can face sunlight directly to generate adequate electric power supply for the fan. Exterior air is guided by the fan inside the hat and distributed on the head by the inner hat body to form convection and make the head comfortable and dry. The inner hat body may comprise a plurality of ribs 11 to fix the shape of the inner layer.</p> |
