1. 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, adapted for mounting to a valve of a pneumatic object, comprises a power inlet connected to said second contact unit of said power supply arrangement and a power outlet connected to said signal generator, wherein when the pneumatic object has a 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 transmit electricity from said power inlet through said second contact unit of said power supply arrangement to said power outlet and generate a warning signal;
wherein said connector is made of electric conductive material and further comprises first and second communicating units on two side ends of said connector respectively, wherein said first communicating unit further comprises;
an interior protruded head, which is transversely extended from a bottom surface of said first communicating unit, having a through hole to form a passage within said bottom surface of said first communicating unit and said through hole of said interior protruded head;
an insulating plate positioned on said 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 is provided inside said insulative element;
a conducting unit; and
a resilient element positioned between said insulative element and said insulating plate, wherein said conducting unit has a first side biasing against said insulating plate and a second side biasing against a free end of said resilient element.

9. 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 (10, 11, 12, 13, 14, 15)
