Abstract

The utility model provides a leakage alarming device which comprises a humidity sensor, an A/D switching circuit connected with an output of the humidity sensor, a one-chip microcomputer connected with an output of the A/D switching circuit, and a telephone autodialing circuit and a sound alarming circuit which are arranged on the one-chip microcomputer, wherein a voice module is arranged at an output terminal of the telephone autodialing circuit. If water leaks from a wall in a rainy day, when the humidity sensor in a switch of the device detects exceeding humidity, a signal is transmitted to the one-chip microcomputer for processing through the A/D switching circuit, then a specific telephone is automatically put through by using the telephone autodialing circuit, a family member is informed by using the voice module, and a speaker also sounds an alarm at the same time to alert people not to use electrical appliances and to turn off a circuit rapidly to prevent burnout of the electrical appliances caused by a short circuit.

Description

A kind of electric leakage alarm device

Technical field

The utility model has related to a kind of electric leakage alarm device.

Background technology

Body of wall leaks and tends to cause the short circuit of household electrical appliance, continues to use power supply such as not to be noted short circuit of people, then is easy to initiation potential, and does not in time cut off the household electrical appliance that circuit can cause using and burn, initiation fire, and accident is serious.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of electric leakage alarm device of reminding body of wall to leak to cause short circuit.

The utility model is achieved through the following technical solutions: a kind of electric leakage alarm device, comprise humidity sensor, and the A/D change-over circuit that links to each other with the humidity sensor output terminal, and the single-chip microcomputer that links to each other with A/D change-over circuit output terminal, and being arranged on telephone automatic dialing circuit and sound warning circuit on the single-chip microcomputer, described voice module is arranged on the telephone automatic dialing circuit output end.

As preferably, described electric leakage autoalarm also is provided with telephone wire break-make testing circuit.

As preferably, described electric leakage autoalarm is arranged in the switch body of wall.

Electric leakage alarm device of the present utility model, rainy day, body of wall leaked, when the humidity sensor in its switch detects humidity over limit, by the A/D change-over circuit signal is transferred to single-chip microcomputer and processes, then automatically put through exclusive phone by the telephone automatic dialing circuit, and inform the household by voice module, loudspeaker also sends alarm sound simultaneously, just advance personnel with prompting and ban use of electrical equipment, and the speed disconnecting circuit, in order to avoid electrical short-circuit is burnt.

Description of drawings

In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.

Fig. 1 is the circuit block diagram of this practical electric leakage alarm device.

Embodiment

As shown in Figure 1, a kind of electric leakage alarm device of the present utility model, comprise humidity sensor 5, and the A/D change-over circuit 6 that links to each other with humidity sensor 5 output terminals, and the single-chip microcomputer 7 that links to each other with A/D change-over circuit 6 output terminals, and being arranged on telephone automatic dialing circuit 8 and sound warning circuit 11 on the single-chip microcomputer 7, described voice module 9 is arranged on telephone automatic dialing circuit 8 output terminals; Rainy day, body of wall leaked, when the humidity sensor 5 in its switch detects humidity over limit, by A/D change-over circuit 6 signal being transferred to single-chip microcomputer 7 processes, then automatically put through exclusive phone by telephone automatic dialing circuit 8, and inform the household by voice module 9, loudspeaker also sends alarm sound simultaneously, just advances personnel to remind.

Wherein, described electric leakage autoalarm also is provided with telephone wire break-make testing circuit 10, and described electric leakage autoalarm is arranged in the switch body of wall.
