A spray washer structure used for attaching to an aircraft and washing insulators on high-voltage transmission lines includes a pivot seat, a core tube, an inner tube, and a nozzle. The bead breaker devices may accordingly follow different geometries of wheel rims without prior knowledge or identification of the specific rim configuration by the machine. The method for manufacturing the light emitting device includes a step of forming a top-gate type transistor for driving a light emitting element.
