[0012] Figure 1 The invention shows an alarm device applied to an intelligent fire centralized power supply control box, comprising a box body, characterized in that an alarm mechanism capable of sensing the occurrence of fire is installed on the side wall of the inner chamber of the box body by screws.

[0013] Furthermore, if Figure 1 As shown, the alarm mechanism includes a shell 1, a float 2, water 3, a sealing film 4, and a conductive wire. The shell 1 is integrally formed with a hollow water injection chamber 11. The bottom surface of the shell 1 is open, and the water injection chamber 11 passes through the bottom surface of the shell 1. The float 2 is built into the water injection chamber 11. After water 3 is injected into the water injection chamber 11, the bottom surface of the shell 1 is sealed by the hot-pressing sealing film 4 to achieve the water injection chamber 11. The float 2 floats on the water surface; the left side of the shell 1 is integrally formed There is a horizontal threading hole one, in which a conductive wire one 51 is connected in series, and a horizontal threading hole two is integrally formed on the right side of the shell 1, in which a conductive wire two 52 is connected in series; a conductive wire three 21 is passed horizontally through the floating block 2, one end of the conductive wire three 21 is located on the left side wall of the floating block 2 and can touch one end of the conductive wire one 51, and the other end of the conductive wire three 21 is located on the right side wall of the floating block 2 and can touch one end of the conductive wire two 52.

[0016] Wherein, the shell 1 and the floating block 2 are both made of plastic.

[0017] like Figure 2 As shown, when a fire occurs, the sealing film 4 heat-sealed on the bottom surface of the shell 1 is burned through by the fire, and the water 3 in the water injection chamber 11 will leak out. At the same time, the float 2 will also fall down. At this time, the conductive wire 3 21 in the float 2 is disconnected from the conductive wire 1 51 and the conductive wire 2 52. The alarm will trigger the fire alarm after sensing the power failure of the circuit.
