ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to an electronic voice device and, more particularly, to an automatic voice device for a fire extinguisher.
BACKGROUND OF THE INVENTION
Along with continual increase of safety consciousness in modern lives, safety requirement of inhabitant environment becomes higher and higher. However, there are still some hazards, such as fires, that can not be completely spared. If fires can be put out immediately when they happen, some misfortunes can be avoided.
Fire extinguishers are indispensable equipment to secure lives and properties of respective families. But the user usually does not know how to operate the fire extinguisher in emergency such that its fire extinguishing function can not be exploited. Moreover, fog usually pervades the fire site such that there is not enough light for the operation guide on the fire extinguisher to be seen clearly. Good chance to put out the fire is thus lost such that the fire can not be put out betimes.
SUMMARY AND OBJECTS OF THE PRESENT INVENTION
The primary object of the present invention is to provide an automatic voice device for a fire extinguisher such that even if there is not enough light in the fire site or fog pervades the fire site, the present invention can also be used to provide verbal explanation of the operation procedures of the fire extinguisher.
Another object of the present invention is to provide an automatic voice device for a fire extinguisher, which will automatically tell the operation procedures of the fire extinguisher when rocked.
According to the present invention, operation procedures of the fire extinguisher are recorded in a voice integrated circuit (IC). The voice IC is connected to a spring rocking switch and the assembly is placed in a metallic case or a plastic case to form a voice device. The voice device is then installed on the fire extinguisher. When the fire extinguisher is rocked, the voice device will automatically tell the user how to operate the fire extinguisher.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawings, in which:
