12. An alert device, comprising:
-
a signal arrangement which comprises a cap, a signal generator received in said cap, and a power supply arrangement which comprises a first contact unit connected to said generator and a second contact unit; and
a connector, made of metallic materials, for connecting to a valve of a pneumatic object, wherein said connector comprises;
a power inlet connected to said second contact unit of said power supply arrangement;
a power outlet connected to said signal generator, wherein when the pneumatic object has an interior pneumatic pressure higher than a predetermined standard pressure, said power inlet and said power outlet are arranged to electrically disconnect with each other, wherein when said pneumatic pressure of said pneumatic object is lower than said predetermined standard pressure, said power inlet and said power outlet is electrically connected to generate a warning signal;
a first and a second communicating units provided at two ends of said connector respectively, wherein said first communicating unit has a through hole to form a passage for air movement between said alert device and the pneumatic object;
an insulating plate positioned on a bottom surface of said second communicating unit;
a conductor mounted on a peripheral portion of said second communicating unit;
an insulative element received in an opening of said second communicating unit while said power inlet provided inside said insulative element;
a conducting unit having a first side biasing to said insulating plate and a second side; and
a resilient element positioned between said insulative element and said insulating plate, wherein a free end of said resilient element is biased against said second side of said conducting unit. - View Dependent Claims (13, 14, 15, 16, 17, 18)
