The two groups of C-shaped air slots in the early warning device shell 1 are in communication with each other. When the fan 4 is working, the air in the air guide pipe 3 will be blown into the cavity inside the early warning device shell 1. After the cold air enters the early warning device shell 1, it will first flow downward through the C-shaped air slot between the inner wall of the early warning device shell 1 and the outer wall of the battery box 5, and then enter the C-shaped air slot in the lower part of the early warning device shell 1 and be discharged outward through the round hole on the outer wall of the early warning device shell 1. During this process, the cold air can absorb the heat on the early warning device shell 1, thereby reducing the heat generated during the fire from being transferred to the storage battery 6 and the early warning device main body 7.

[0034] In the embodiments of the present disclosure, as shown in Figures 1-5As shown, the outer wall of the early warning device housing 1 is provided with eighteen holes, which are in communication with the C-shaped air slot of the lower part of the early warning device housing 1. When the fan 4 is working, the air in the air duct 3 will be blown into the cavity of the early warning device housing 1. The cold air entering the early warning device housing 1 will first flow downward through the C-shaped air slot between the inner wall of the early warning device housing 1 and the outer wall of the battery box 5, and then enter the C-shaped air slot of the lower part of the early warning device housing 1 and be discharged outward through the holes on the outer wall of the early warning device housing 1. In this process, the cold air can absorb the heat on the early warning device housing 1, reducing the heat generated during the fire from being transferred to the battery 6 and the early warning device main body 7.

When a fire occurs, the early warning device main body 7 will detect and issue an alarm, and will also control the fan 4 to operate. When the fan 4 is working, the air in the air duct 3 will be blown into the cavity of the early warning device housing 1. At the same time, the cold air above the ground will also continuously enter the air duct 3. After the cold air enters the early warning device housing 1, it will first flow downward through the C-shaped air slot between the inner wall of the early warning device housing 1 and the outer wall of the battery box 5, and then enter the C-shaped air slot of the lower part of the early warning device housing 1 and be discharged outward through the holes on the outer wall of the early warning device housing 1. In this process, the cold air can absorb the heat on the early warning device housing 1, reducing the heat generated during the fire from being transferred to the battery 6 and the early warning device main body 7, so as to ensure that the battery 6 and the early warning device main body 7 work normally. Moreover, in the use process, the lower protective cover 8 can shield and protect the early warning device main body 7, avoiding the early warning device main body 7 from contacting open flames. Moreover, the double-layer rectangular plate at the bottom of the lower anti-skid cover 8 can also play a heat insulation effect, and the hole on the lower anti-skid cover 8 can also ensure that the alarm bell of the early warning device main body 7 transmits outward.
