Abstract

An earthquake alarm device, including an alarm lamp and a base. Inside the alarm lamp, there is a power supply module and an earth magnetic field detection module. The earth magnetic field detection module emits a sound and light early warning signal when identifying any earth field abnormality. The vibration sensing module I senses slight vibration and emits a sensing signal I. The vibration sensing module II senses strong vibration and emits a sensing signal II. The control chip II emits sound and light alarm signals after receiving the sensing signal II or the sensing signal I and sound and light early warning signal at the same time. The alarm lamp gives a light alarm after receiving a sound and light early warning signal. The lighting module receives sound and light early warning signals or sound and light alarm signals and provides lighting.

Dependent claims

An earthquake alarm device, comprising:

a base;
an alarm lamp removably coupled to the base;
an earth magnetic field detection module contained within the alarm lamp, wherein the earth magnetic field detection module emits an early warning signal upon identification of an earth magnetic field abnormality and the alarm lamp emits a light alarm responsive to the early warning signal;
a vibration sensing module I contained within the alarm lamp, that senses a less than magnitude 4 earthquake vibration and emits a sensing signal I;
a vibration sensing module II contained within the alarm lamp, that senses a magnitude 4 and larger earthquake vibration and emits a sensing signal II;
a control chip II contained within the alarm lamp that emits an alarm signal responsive to at least one of the sensing signal II and a concurrence of the sensing signal I and the early warning signal;
a sound alarm unit contained within the alarm lamp responsive to at least one of the early warning signal and the alarm signal and that audibly alarms;
a lighting module contained within the alarm lamp responsive to at least one of the early warning signal and the alarm signal to provide lighting;
