Description

  The present invention relates to a manual charging radio useful in an emergency such as a disaster.

For example, there is a radio light with a hand-wound mobile phone charging function described in Patent Document 1. This is a small radio with an LED light and an emergency siren that converts the kinetic energy generated by hand-winding operation of the handle to an output connector for connecting to a mobile phone via a connection cord into electricity. The internal storage battery is charged, and the LED light, the emergency siren or the radio can be used by the storage battery, and the rechargeable battery in the connected mobile phone can be charged. It is a feature.
Then, the cellular phone can be charged by generating power by manually winding the handle. Therefore, even if there is no electrical outlet, the mobile phone can be charged easily anytime and anywhere, and it is safe even if the battery runs out unexpectedly. In addition to the charging function of the mobile phone, it also has an LED light, an emergency siren, and a radio.
By the way, when the disaster is an earthquake, for example, and when the earthquake occurs in the nighttime bedtime, it is important to recognize what happened as soon as possible. You need to have enough light to take action quickly. Also, if you listen to disaster prevention radio broadcasts, you can easily take appropriate actions.
In this regard, nothing has emerged as a precaution.

The light 6 on the left side is composed of two white LED lights 6a and 6b. At the upper left changeover switch 27, “OFF”, “weak” illumination with one white LED lit, and two white LEDs lit. The “strong” lighting can be switched and lit. The light 6 is activated for a certain period of time, for example, one minute, as the seismic sensor 8 outputs a seismic signal.
The siren 7 is configured to be “ON” and “OFF” with the change-over switch 28 on the lower left side of the back surface portion 1b. The siren 7 is activated when a seismic signal is output from the seismic sensor 8 and generates an electronic pulsating sound for a certain time, for example, 1 minute.
The seismic sensor 8 has a set operation sensitivity set to seismic intensity 4 (25 gal to 80 gal) or more, and the seismic intensity 4 is ON when the changeover switch 28 is switched to the “seismic” position when connected to a commercial AC power supply. As the above earthquakes are detected, a seismic signal is output to the control circuit 36, and the light 6 and the siren 7 are activated in response to the operation signal from the control circuit 36.

The case 1 has a DC converter connection terminal 29 for a commercial AC power source in the lower left corner, and the storage battery 4 can be charged from the commercial AC power source. The rechargeable battery of the mobile phone can be charged through an external power supply charging circuit 30 including an overcharge prevention circuit that detects charging and stops charging.
