[0040] The controller 2 is fixedly mounted on an outer wall of one side of the box body 1 .

[0041] As can be seen from the above, after an open flame or smoke is generated inside the box 1, the fire extinguishing program of the device is triggered, the gas storage mechanism 3 opens to discharge the fire extinguishing agent, and then the exhaust mechanism 16 sends the fire extinguishing agent into the interior of the box 1. The exhaust mechanism 16 is driven to move back and forth by the moving mechanism 14, so as to facilitate the rapid filling of the fire extinguishing agent into the interior of the box 1, extinguish the fire source, and prevent the fire from further expanding.

[0042] Specifically, a photosensitive fire detector 11 is fixed to the upper part of the inner wall of one side of the box body 1 by bolts, and an alarm 4 is installed on the top outer wall of the fixed box 5 .

[0043] As can be seen from the above, the photosensitive fire detector 11 is set to monitor in real time whether there is smoke or open fire inside the box 1. When an abnormality is detected, a signal will be transmitted to the alarm 4 and the controller 2, the alarm 4 will sound an alarm, and the controller 2 will start the fire extinguishing program.

[0049] As can be seen from the above, starting the electric slide rail 1401 drives the movement of the slider 1402, and then drives the movement of the connecting rod 1403 and the ring 1404, so as to facilitate the reciprocating movement of the exhaust mechanism 16.

[0050] Specifically, the exhaust mechanism 16 includes a fixed pipe 1601, a plurality of exhaust pipes 1602 are plugged into the bottom end of the fixed pipe 1601, one end of the exhaust pipe 1602 passes through the corresponding strip opening 15 and is located inside the box body 1, a flaring bucket 1603 is sleeved on the bottom end of the exhaust pipe 1602, a telescopic pipe 1604 is plugged into the top end of the fixed pipe 1601, the telescopic pipe 1604 is plugged into the circumferential inner wall of the collar 1404, and the top end of the telescopic pipe 1604 is plugged into one end of the outlet pipe 303.

[0051] As can be seen from the above, the fire extinguishing agent discharged from the outlet pipe 303 is sent into the fixed pipe 1601 through the telescopic tube 1604, and then sent into the multiple exhaust pipes 1602, so that the fire extinguishing agent is sent into the interior of the box 1, and the exhaust pipe 1602 is driven to move back and forth by the electric slide rail 1401, so that the fire extinguishing agent can quickly fill the box 1, put out the open fire, and prevent the fire from further expanding.

[0052] Working principle: When the device is in normal use, the photosensitive fire detector 11 is used to detect in real time whether smoke and open flames are generated inside the box 1.
