Abstract
The utility model relates to a water leak alarm, which comprises a cuboid-shaped plastic housing defining a cavity, a loudspeaker disposed at the top inside the housing, a circuit board disposed in the middle inside the housing, an alarm LED, a power indicator LED and a switch all disposed on the lateral inner wall of the housing, and two external contacts disposed outside the housing. The circuit board is provided with an audio chip HT812DO whose FLAG1 pin is connected to the alarm LED, a resistance and a VDD pin of the chip in order. An AUD pin of the chip is connected to a base electrode of a triode 8050. A collector electrode of the triode is connected to the loudspeaker and the VDD pin of the chip in order. An emitting electrode of the triode is connected to one of the external contact. A KYE1 pin of the triode is connected to another external contact. A VSS pin of the triode is connected to the power indicator LED, resistance, switch and power cathode in order. The power anode is connected to the loudspeaker and the VDD pin of chip respectively. The utility model can provide real-time alarm for leakage of water supply or heating pipeline.
Description
1, technical field: water leakage alarm device of the present utility model relates to a kind of warning device, relates in particular to a kind of electronic installation of reporting to the police to leaking.
2, background technology: " run, drip, leak " phenomenon often takes place in the joint of indoor running water pipe or caliduct, thereby damages floor, carpet and furniture, and severe patient even bring disaster to neighbours downstairs causes neighborhood relationship to be discord.Having not yet to see can be to the leak device of instant alarming of interior conduit.
3, summary of the invention: the purpose of this utility model be to propose a kind of can be to the water leakage alarm device of the indoor instant alarming that leaks.
The purpose of this utility model be achieved in that water leakage alarm device by the outer two external contacts of warning light emitting diode, power supply indication light emitting diode, switch and the shell of the circuit board at loudspeaker, the middle part of cavity rectangular parallelepiped plastic casing and its internal upper part of installing, sidewall for mainly to form.Installing speech chip HT812DO on the circuit board, its FLAG1 pin joins in proper order by the VDD pin of warning light emitting diode, resistance and chip, the AUD pin of chip and the base stage of triode 8050 are joined, the VDD pin of the collector of this pipe and loudspeaker, chip joins in proper order, and an emitter and an external contact join.The KYE1 pin of chip and another external contact join, and the VSS pin indicates light emitting diode, resistance, switch and power cathode order to join by power supply, and positive source joins with the VDD pin of loudspeaker and chip respectively.When soaking two external contacts when leaking, circuit turn-on, the warning light emitting diode is lighted, and 8050 pairs of voice signals of triode amplify the loudspeaker sounding alarm.
Owing to carry out such scheme, this device can be when running water pipe or caliduct leak instant alarming.
4, description of drawings: concrete structure of the present utility model is provided by following drawings and Examples
Fig. 1 is the water leakage alarm device structural representation
Fig. 2 is the water leakage alarm device circuit diagram
5, embodiment:
Legend: 1, loudspeaker 2, external contact 3, housing 4, warning light emitting diode 5, switch 6, power supply indication light emitting diode 7, speech chip 8, triode
Embodiment: shown in Fig. 1-2, water leakage alarm device by the outer two external contacts 2 of warning LED 2, power supply indication LED 1, switch 5 and the shell of the circuit board at the loudspeaker 1 of cavity rectangular parallelepiped plastic casing 3 and its internal upper part of installing, middle part, sidewall for mainly to form.Installing HT812DO speech chip 7 on the circuit board, its FLAG1 pin joins in proper order by the VDD pin of warning LED 2, resistance and speech chip 7, the AUD pin of speech chip 7 and the base stage of triode 8050 are joined, the VDD pin of the collector of this pipe and loudspeaker 1, speech chip 7 joins in proper order, and an emitter and an external contact 2 join.The KYE1 pin of speech chip 7 and another external contact 2 join, and the VSS pin joins in proper order by power supply indication LED 1, resistance and switch 5, power cathode, and positive source joins with the VDD pin of loudspeaker 1 and speech chip 7 respectively.Two external contacts 2 are the lead of termination bare metal silk.
During use, with the pipe joint below that water leakage alarm device places suspection to leak, open switch 5, power supply indication light emitting diode 6 is lighted, and two external contacts 2 is kept flat on the floor get final product.In case when pipe leakage, the water logging on the floor were crossed two external contacts 2, the warning LED 2 of device can be lighted, loudspeaker 1 is sounding alarm simultaneously.Lack of water city water at general midnight, place the two external contacts 2 of this device at the bottom of the vegetable sink under the kitchen faucet on, the tap of fetching boiling water when waiting water, can be reported to the police and inform, can make the resident avoid staying up late to do to wait or come water and the people sleeps and wastes water.
