Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an earthquake breaker in which an electric stove which is dangerous during an earthquake is automatically opened, and a lamp such as a radio or a guide light required during an earthquake is closed.

[0002]

2. Description of the Related Art Conventionally, there was a circuit breaker capable of automatically stopping an oil stove or city gas product during an earthquake, but a switch that automatically opens an electric product such as an electric stove that is dangerous during an earthquake is manufactured. It has not been. On the other hand, there were switches on the market that automatically turned on only the necessary guide lights during an earthquake.

[0003]

Conventionally, in the case of an earthquake, a dangerous electric stove or the like is automatically set to an open circuit to cut off the current, and conversely, a lamp required for an earthquake such as a radio or guide light can be simultaneously turned on. There wasn't. In addition, even in the event of a power failure, none of the batteries, such as induction lights, could be turned on by the built-in battery. Furthermore, there was no seismic breaker that could be plugged into a 100V volt outlet. INDUSTRIAL APPLICABILITY The present invention not only automatically cuts off the electric current of a dangerous electric stove during an earthquake, but also automatically switches on a lamp such as a radio or a guide light required during an earthquake, or operates even during a power failure during an earthquake. As described above, the purpose is to be able to turn on the lamp such as the built-in induction light by the built-in battery, and also to provide the seismic breaker of the outlet insertion type so that it can be put to practical use simply by plugging it into the existing outlet. .

[0004]

In order to achieve the above object, in an earthquake breaker of the present invention, a sensor such as a vibration sensor or a piezoelectric sensor for detecting an earthquake, a switch interlocking with the sensor, and an open circuit during an earthquake are provided. It is equipped with a terminal or an outlet and a reset button that returns the built-in switch that has been activated due to an earthquake etc. to the initial state. Further, in claim 2, a lamp is provided which is automatically turned on at the time of an earthquake. According to the third aspect, the terminal or the outlet which is a closed circuit at the time of earthquake is provided. In claim 4, a battery for lighting the built-in lamp is provided. Further, in claim -5, a terminal that can be inserted into an existing outlet is provided.

[0005]

[Operation] When a strong earthquake occurs, the built-in vibration sensor activates the built-in switch, and the dangerous electric products such as electric stoves, electric kotatsu, etc. that were plugged into a terminal or an outlet that can be switched off by the earthquake and were operating before the earthquake Is automatically turned off, and conversely, the switches for electrical appliances necessary for an earthquake such as a radio or a guide light that were plugged into the terminal or outlet that is switched on by the earthquake are automatically turned on. To cancel, press the reset button to return to the initial state. Further, a lamp such as a guide light built in the earthquake breaker can be turned on during an earthquake. Furthermore, assuming that the power supply itself such as 100 volt will be cut off by an earthquake, the built-in battery can turn on the lamp such as the built-in guide light.

[0006]

EXAMPLES Examples will be described with reference to the drawings.
In FIG. 1, the earthquake breaker 20 includes a vibration sensor 1 and a switch 2 that operates by the vibration sensor 1.
A rechargeable battery or a disposable battery 9 is stored in the battery storage unit 8. A charger 10 including a transformer and a rectifier is built in for a rechargeable battery. Further, it comprises an outlet insertion opening 6 which becomes a closed circuit in the event of an earthquake, an outlet insertion opening 7 which becomes an open circuit in the event of an earthquake, a reset button 4, a lamp 5 and an existing outlet insertion terminal 3.

[0007]

Since the present invention is constructed as described above, it has the following effects. Earthquake breaker 2
By inserting 0 into the existing outlet, when a vibration exceeding a certain level is applied to the earthquake breaker 20 due to an earthquake, the built-in vibration sensor 1 detects it and the built-in switch 2 automatically operates. As a result, the electric current of dangerous electric products such as electric stoves and electric kotatsu that were plugged into the outlet 7 which becomes an open circuit in the event of an earthquake is shut off, and even if a house collapses, a fire will be prevented. it can.
In addition, information such as radio and guide lights plugged into the outlet 6 which becomes a closed circuit due to the earthquake, necessary information when an electric current flows through the built-in lamp 5 such as a guide light, and a passage to the evacuation gate can be known. Also, since the built-in lamp 5 lights up,
It is easy to see that the seismic breaker 20 is in an operating state by just seeing it, and since the room is illuminated brightly at night, it is possible to avoid falling objects and to evacuate safely. Therefore, not all the electric products at the time of the earthquake are necessarily open circuit, but the electric products required at the time of the earthquake can be closed circuit. Further, since the battery 9 is stored, the built-in lamp 5 can be turned on by the battery 9 even when the power is cut off, such as 100 V, and the power is out. In this case, if the earthquake breaker 20 is pulled out from the existing outlet, it can be used as a temporary flashlight.
Even in the case of a disaster such as a fire, which is not an earthquake, the vibration sensor 1 can be operated by operating the vibration sensor 1 by turning on the built-in lamp 5 by tapping the earthquake breaker from the existing outlet with a strong hand to make it a temporary flashlight. When the battery 9 is a rechargeable battery, it is always in a charging completed state by the charger 10 that rectifies a 100-volt power supply and lowers the voltage.
Always available. When the seismic breaker 20 is accidentally actuated, or when the seismic breaker 20 is actuated by an earthquake and wants to be restored as the original seismic breaker, the built-in switch 2 can be returned to the initial state by pressing the reset button 4. In this embodiment, the plug-in type is described, but of course, it can be used as a breaker usually installed on the upper part of the wall surface, and it is naturally possible to incorporate the breaker inside an electric product, and these are also included in the present invention.
