Ring device is connected to the cathode of power supply.
It further, further include base protection resistor, first probe is connected to triode by base protection resistor
Base stage.
It further, further include collector protective resistance, the collector of the triode is connected by collector protective resistance
To the anode of power supply.
Further, further include light emitting diode, the light emitting diode be connected to triode emitter and buzzer it
Between.
Further, the shell further includes support chip, and the support chip is set on the bottom edge position of lower case.
Further, the triode is S8050.
Further, the probe is iron bar.
Further, the power supply is 9V DC power supply.
The beneficial effects of the invention are as follows：The present invention provides a kind of the leak overflow annunciator based on probe in detecting, alarm
The first probe and the second probe in device were to disconnect originally, and when the first probe and the second probe are all immersed in water, first is visited
Needle and the second probe are connected, and at this time the anode of the base stage of triode and power supply is connected, and the collector of triode be also with
What the anode of power supply was connected, at this time all in high level, triode ON drives buzzer for the base stage of triode and collector
It makes a sound, plays and user is reminded the case where leak spilling water occur.
Detailed description of the invention
The invention will be further described with example with reference to the accompanying drawing.
Fig. 1 is a kind of structure chart of the leak overflow annunciator based on probe in detecting of the present invention；
