description The utility model relates to a fire alarm device. The fire alarm device comprises an outer cover, a motor, a connecting assembly and an alarm. Air suction grooves are formed in the outer surface of the outer cover in an array mode. First fixing blocks are arranged in the outer cover in an inner array mode. The motor is mounted on the inner top wall; a hemispherical shell is arranged below the motor; third fixing blocks are installed at an end opening of the hemispherical shell in an annular array mode, two second fixing blocks are installed on the inner side wall of the hemispherical shell and located below the first fixing blocks, and the alarm is arranged on the two second fixing blocks through connecting assemblies; a sensor is arranged at the bottom of the alarm. The alarm is mounted in the outer cover, the motor is arranged above the alarm to drive the fan to perform air suction, and the alarm is arranged below the fan, so that absorbed heat and smoke can pass through the inductor below the alarm at the
