Through the operation of the blades, the fire extinguishing sand is evenly scattered around, which can timely and effectively control the accidental fire, thereby avoiding greater losses.
[0015] 2. In the event of an accidental fire, the present invention controls the first motor through a controller to move the baffle upward and fit with the first through groove and the second through groove while the second motor is running, so that the interior of the base box is isolated from the interior of the box body, reducing the entry of outside air and preventing the fire extinguishing sand from entering the interior of the base box, thereby increasing the fire extinguishing efficiency.

[0021] Specifically, through the operation of the high-temperature smoke sensor 12, the interior of the box body 1 can be sensed for an accidental fire, and after sensing the accidental fire, the signal is transmitted to the controller, which is not shown in the figure. The fire extinguishing sand 32 is stored in the fire extinguishing sand storage box 10, and the fire extinguishing sand 32 is limited in the interior of the fire extinguishing sand storage box 10 by the limit plate 28 to prevent it from falling into the interior of the box body 1 when there is no accidental fire. The second shaft 30 is driven to rotate by the operation of the second motor 29, thereby driving the blade 31 to operate, so as to stir and break up the fire extinguishing sand 32. Through the operation of the electric push rod 11, the connecting member 25 is driven to move downward, and the limiting ring 27 is used to limit the position, so that the interior of the fire extinguishing sand storage box 10 is connected to the interior of the box body 1 through the connecting member 25, and the fire extinguishing sand 32 falls into the interior of the box body 1 through the surroundings of the connecting member 25.
