Hand-drier for playing videos and audio tracks has a casing with an air outlet, a control circuit board and sensors to trigger a fan and a video/audio playback system

摘要

A fan (120) fits in a casing (110) with an air outlet (AO) (112) and corresponds to the AO. A control circuit board (CCB) (130) inside the casing has an electric link to the fan. A first sensor (140) extends outwards through the AO with an electric link to the CCB so as to make a first signal available to the CCB for triggering the fan.
