Description

[Detailed description of the invention] This invention relates to a flashlight installed in each room of an inn or hotel, and by incorporating a built-in alarm device,
The purpose is to provide a flashlight that automatically emits an alarm sound and lights up a light bulb in the event of an emergency.

Figure 1 shows a conventional flashlight and how it is installed.A rechargeable battery is built into the flashlight body 1.
With the plug 2 of the main body 1 inserted into an AC power outlet 3, the main body 1 is locked to a locking tool 5 on a pillar 4 in a room.

While the plug 2 is inserted into the outlet 3, the battery is charged, but in this state the switch is open and the light bulb in the main body 1 is configured not to light up.

When the plug 2 of the main body 1 is pulled out from the outlet 3, the battery of the main body 1 is configured to light up.

It is also conceivable that the above switch be operated manually.

The present invention is intended to automatically generate an alarm sound and turn on the light bulb by incorporating an alarm device into such a flashlight.The following is a drawing showing an embodiment of the present invention. Refer to and explain.

As shown in FIG. 2, a plug 7 connected to a 100 volt commercial AC power source 6 is provided and connected to an input terminal of a charger 8.

The output terminal of this charger 8 is connected to a rechargeable battery 10 via a backflow prevention diode 9.

A light bulb 12 is connected to this battery 1o via a switch 11.

Switch 11 may be a manually operated switch, and plug 7
It may also be a switch that is turned on when it is unplugged from the outlet 6.

A switch 13a of a relay 13 is connected to this switch 11 in parallel.

The plug is connected to a tuning section 15a in the receiving device 15 via a capacitor 14.

This receiving device is designed to receive, for example, training radio waves received from a commercial AC power line as an antenna, and has an antenna configuration in which the tuning coil of the tuning section 15a is wound around a ferrite core so that radio waves can be received independently. It's good to keep it.

The receiving device 15 includes an oscillation mixing section 151 in addition to the receiving section 15a.
) An XIF section 15c1 and a detection section 15d are provided.

The output of the detection section 15d is applied to a detection circuit 16 that detects an alarm signal that is a specific code signal included in the received signal.

The output of the detection circuit 16 is applied to the audio circuit 17 to generate an alarm sound.

This warning sound may be of any type; for example, a voice synthesis circuit may be used to say "Please evacuate immediately", or a radio broadcast obtained by the detection section 15d may be amplified and broadcast. good.

Further, the output of the detection circuit 16 is applied to a relay drive circuit 18, which is configured to close the switch 13a of the relay 13 when an alarm signal is detected.

When an emergency situation occurs, when AM (medium wave) alarm signals are issued from all broadcast stations, this signal is transmitted to the receiving device 15.
and enters the detection circuit 16.

When an alarm sound is detected by this detection circuit 16, an audio circuit 17
The alarm sound is emitted, and at the same time the switch 13 of the relay 13 is activated.
A is turned on and the light bulb 12 lights up.

As a result, a warning can be issued automatically, and even in the event of a power outage, the light bulb 12 will turn on, so the flashlight can be immediately taken out.

Even if you take out the flashlight, the tuning unit 15a can receive the alarm signal, so the alarm sound can continue to be emitted, and the light bulb 12
can also be turned on.

When the switch 11 is turned on, lighting is ensured.

As described above, according to the present invention, by adding an alarm device to the flashlight main body, it is possible to automatically emit an alarm sound and also to light up a light bulb.
