One end of KT-2, the delay of time relay KT disconnect the instantaneous other end for being closed normally-closed contact KT-2 and are coupled by buzzer SP
In the cathode of power supply.
Light-emitting alarm 6 includes the normally opened contact KA-1 and strobe light emission diode (LED) of relay KA, the reset portion that shines 8
One end coupling of instantaneous closure normally-closed contact KT-1, the normally opened contact KA-1 of relay KA are disconnected for the delay of time relay KT
In the anode of power supply, the delay that the other end is coupled to time relay KT disconnects instantaneous one end for being closed normally-closed contact KT-1, when
Between the delay of relay KT disconnect the sun that the instantaneous other end for being closed normally-closed contact KT-1 is coupled to strobe light emission diode (LED)
The cathode of pole, strobe light emission diode (LED) is coupled to the cathode of power supply.
The self-locking device 9 for making light-emitting alarm 6 keep alert status is coupled on light-emitting alarm 6.Self-locking device 9
Including be set to the hull outside of water dispenser with detect human body closer or far from and export the human testing of human testing signal
Unit 10, human testing unit 10 are rpyroelectric infrared detection circuit comprising pyroelectric sensor N1, pyroelectric sensor N1
Input terminal be coupled to voltage V1, output end exports corresponding human testing signal, the ground terminal ground connection of pyroelectric sensor N1.
And pyroelectric sensor N1 is set to the hull outside of water dispenser, can more delicately monitor human body.
Pyroelectric sensor is mainly the detecting element made of the material of high Seebeck coefficient, is packed into each detector
One or two detecting element, and by two detecting elements with opposite polarities in series, to inhibit to generate since own temperature increases
Interference；The infra-red radiation for detecting and receiving is transformed into faint voltage signal by detecting element, through in probe

Alert device 6 keeps alert status；Conversely, when human testing unit 10 detects human body far from water dispenser, execution unit 11 is cut off
Light-emitting alarm 6.
Specific work process is as follows：
When the attaching plug 13 of water dispenser is plugged on socket, if socket can normal power supply, the power supply of water dispenser
Circuit is switched on so that the coil of relay KA and time relay KT obtain electric actuation, the normally opened contact KA- of relay KA simultaneously
1 is closed at KA-2, so that strobe light emission diode (LED) and the current supply circuit of buzzer SP are all switched on so that stroboscopic
Light-emitting diode LED carries out light flash, while buzzer SP sounding is prompted, to remind user that water dispenser powers on success.
Simultaneously, time relay KT is clocked into state, is arrived when the time cycle one of setting, then time relay KT is corresponding prolongs
When disconnect the instantaneous normally-closed contact KT-1 and KT-2 that is closed and all disconnect, to cut off strobe light emission diode (LED) and buzzer SP
Current supply circuit so that strobe light emission diode (LED) is all stopped with buzzer SP.
If human body is also near water dispenser at this time, pyroelectric sensor N1 is able to detect that human infrared radiation, to
The human testing signal of high level is exported to the base stage of triode Q1, so that triode Q1 is connected, the coil of relay K obtains electric suction
It closes, corresponding normally opened contact K-1 is closed, the current supply circuit of strobe light emission diode (LED) is connected so that two pole of strobe light emission
Pipe LED continue workings；Conversely, if human body can't detect human infrared radiation far from water dispenser, pyroelectric sensor N1, from
And low level human testing signal is exported to the base stage of triode Q1, so that triode Q1 is ended, the deactivation coil of relay K is replied by cable
Position, corresponding normally opened contact K-1 are disconnected, and to cut off the current supply circuit of strobe light emission diode (LED), make strobe light emission diode
LED stops flicker.
If after the plug 13 that plugs in, socket can not normal power supply, then the coil of relay KA can not obtain electric, institute it is right
The normally opened contact KA-1 answered and KA-2 all is at off-state so that strobe light emission diode (LED) all stops with buzzer SP
It only works, to prompt people's water dispenser not power on success currently.
