If the device body 1 accidentally catches fire and explodes, the dry powder in the airbag 10 can play a certain flame retardant role to avoid the occurrence of large-scale fires.

[0026] like Figure 1As shown, the main pipeline 7 is connected with the vertical pipe 8, and a plurality of connecting pipes 9 are fixedly installed on the main pipeline 7 and the vertical pipe 8, and the connecting pipe 9 is fixedly connected with the air bag 10. The main pipeline 7 and the vertical pipe 8 are both connected with the connecting pipe 9, and the connecting pipe 9 is connected with the air bag 10. The dry powder tank 11 is fixedly installed with a connecting pipe 6 at one end away from the main pipeline 7, and the connecting pipe 6 is connected with the dry powder tank 11. The air pump 5 is fixedly installed at one end of the connecting pipe 6 away from the dry powder tank 11. By setting the connecting pipe 9, and the connecting pipe 9 is fixedly connected and connected with the main pipeline 7, the vertical pipe 8 and the air bag 10, the main pipeline 7 and the vertical pipe The gas in 8 is rushed into the airbag 10 through the connecting pipe 9. By providing an air pump 5, when the air pressure sensing device detects that the air pressure in the device body 1 is too high, an electrical signal is sent to the air pump 5, so that the air pump 5 works and rushes gas into the connecting pipe 6. The connecting pipe 6 is connected with the dry powder tank 11, and the main pipeline 7 is connected with the dry powder tank 11, so that the gas enters the dry powder tank 11 through the connecting pipe 6, and the dry powder in the dry powder tank 11 is brought into the airbag 10, so that when the airbag 10 is broken, the dry powder therein can play a certain flame retardant effect.
