In particular to the embodiment of the present application, the blasting cartridge 20 has a connecting end 23 and a closed end 24, the connecting end 23 being connected to the outer shell 10. Further, the blasting cartridge 20 has a gap between the inner wall of the outer casing 10 and other parts except the connecting end 23 contacting the outer casing 10, that is, the blasting cartridge 20 further includes a side wall 25 connecting the connecting end 23 and the closed end 24, and the side wall 25 and the closed end 24 have a gap between the inner wall of the outer casing 10. Thus, the force applied to the shell 10 by the blasting shell 20 during blasting can be reduced, and the shell 10 can be prevented from being damaged.

In some embodiments, the burst shell 20 is capable of at least partial breakage when the pressure in the second storage chamber 21 reaches the burst pressure value, at the non-connected end 23. Since the connection end 23 is in direct contact with the housing 10, if the connection end 23 is damaged, the housing 10 may be damaged, and further, gas may leak, and the first storage chamber 11 and the second storage chamber 12 may not be communicated with each other, so that the fire extinguishing stability of the fire extinguishing apparatus 100 may be improved by avoiding the non-connection end 23. Specifically, it is possible to make the ignition end of the gas generating agent 22 away from the connection end 23, or to enhance the fastening action between the connection end 23 and the housing 10, or the like.

In some embodiments, the fire extinguishing apparatus 100 further comprises an ignition element 40, one end of the ignition element 40 is located outside the casing 10, and the other end is connected to the gas generating agent 22 in the blasting shell 20 through the casing 10.

By coating the gas generant 22 with a coating, the gas generant 22 can be stably combusted to continuously generate gas, and the coating has the effects of heat insulation, shock resistance and salt corrosion resistance, thereby improving the IP protection grade of the gas generant 22. Specifically, the wrapping member includes wrapping silica gel. In other embodiments, when the second housing 20 is a long strip, the covering member may not be used, and the gas generating agent 22 may be filled in the second storage cavity 21, so that the second housing 20 achieves the same technical effect as the covering member.

In another embodiment of the present application, the shell 10 is connected to the blasting cartridge 20 by an igniter 40. I.e. the shell 10 and the blasting shell 20 may be indirectly connected to each other.

Specifically, the blasting cartridge 20 may be hung in the first storage chamber 11. More specifically, the pilot 40 is connected to the top of the housing 19. In this way, the blasting cartridge 20 can be hung in the first storage chamber 11 in the direction of gravity after the fire extinguishing apparatus 100 is normally installed. In other embodiments, where the extinguishing agent 12 is a liquid extinguishing agent, the burst shell 20 may also be suspended in the liquid extinguishing agent.

In some embodiments, the blasting cartridge 20 is in the form of a bag. Bag-shaped material is frivolous, has reduced the blasting degree of difficulty to, when receiving external shock or external force, accessible form change in time adjusts the atress, avoids the damage, has played fine isolated effect.
