The abnormal warning apparatus essentially includes a brightness tuning device, a light detecting unit, an analysis circuit, a light emitter, and an alarm. The ray of the light emitter penetrates through the tube having the brightness tuning device and enters the light detecting unit on the other side. After that, the various voltages transformed from the received ray with strong or week brightness or no light received are entered into the analysis circuit, then the voltages are determined to be normal or abnormal by comparing them with a standard voltage. The alarm goes off to warn with sound or light based on an output of abnormal voltage if the flow stops or becomes insufficient.Type: ApplicationFiled: March 15, 2007Publication date: October 4, 2007Inventor: Qiang-Fei Duan
