Abstract
The utility model discloses a multi-purpose overflow alarm. The alarm comprises a first resistor, a second resistor, a third resistor, a fourth resistor, a first NAND gate, a second NAND gate, a third NAND gate, a fourth NAND gate, a first capacitor, a second capacitor, a third capacitor, a first diode, a second diode, a sensor, a relay, a switch, a power supply, a triode and a buzzer. A first terminal of the first resistor is connected with a first terminal of the first NAND gate, a second terminal of the first NAND gate and a first terminal of the sensor respectively. The multi-purpose overflow alarm is formed by a trigger circuit and an oscillation circuit. At ordinary times, the sensor is in an open circuit state. The third NAND gate outputs a low level and the buzzer do not alarm. Once the sensor is contacted with water, the third NAND gate outputs the low level and the fourth NAND gate outputs a high level; the levels are fed back to the second NAND gate to carry out digital display self-locking via the first diode and simultaneously an oscillator works and drives the buzzer to give an alarm. The circuit can timely emit the alarm when water overflows so that water resources are saved.
