<p>A radio transmitter and a radio receiver for automatically detecting gas leakage of a tire are provided. The transmitter mainly comprises a case (1),a gas switch (2), a thimble (3), a pressure spring (4), a fixing plate (5), an elastic electric switch (6), a battery (8) and a transmitter assembly (7). The receiver mainly comprises an indicator lamp (11), a power plug (9), a prompting device (12) and a receiver assembly (13). The thimble (3) controls opening and closing of the elastic electric switch (6) through the fixing plate (5) and the pressure spring (4) under variation of the air pressure of the tire. The elastic electric switch (6) controls opening and closing of the transmitter assembly (7) and the battery (8).The power plug (9) of the receiver is connected with a vehicle power supply and is communicated with the receiver assembly (13). The receiver assembly (13) controls opening and closing of the indicator lamp (11) and the prompting device (12) arranged in a shell of the receiver. The receiver receives a signal from the transmitter and orders the indicator lamp (11) to light and the prompting device (12) to send a voice signal to prove gas leakage of the tire. In contrast, if the indicator lamp (11) is not lit, and the prompting device (12) does not send voices, the tire is not in gas leakage.</p> |
