Specifically, the pressure relief element is a pressure relief diaphragm, and the pressure relief diaphragm is sealed at the position of the spout 13.
In one embodiment, referring to fig. 2 and 3, fig. 2 shows a cross-sectional view of the fire-extinguishing container shown in fig. 1 taken along a-a, and fig. 3 is a schematic structural view of a flame-extinguishing and sound-attenuating member of the fire-extinguishing container shown in fig. 1. The body 21 has a passage 211, the side of the body 21 is provided with a flame and sound absorbing hole 22, and a gap is formed between the body 21 and the housing 10. When the fire extinguishing container is used, a fire extinguishing agent is placed in the fire extinguishing agent chamber 11, and a coolant is placed in the coolant chamber 12. The fire extinguishing agent in the shell 10 is ignited, when the fire extinguishing agent is a powdery or small block-shaped agent, the fire extinguishing agent is burnt violently, a large amount of fire extinguishing substances can be generated in the moment of burning, a large amount of heat is generated at the same time, and huge sound is generated after the fire extinguishing agent is started. Through setting up flame sound-absorbing hole 22 at body 21, after the fire extinguishing generating agent was ignited, partial high-pressure gas in casing 10 passed through flame sound-absorbing hole 22 and got into in the clearance between casing 10 and body 21 for gas gets into a relatively great space, can slow down the expanding velocity of gas like this, reaches the effect of noise reduction.

The peripheral wall of the flame-quenching hole 22 has a flow guide part 221, and the flow guide direction of the flow guide part 221 faces the outside of the body 21. It can be understood that the hole wall of the flame suppression hole 22 has a certain thickness, and the flow guide part 221 is located on the hole wall of the flame suppression hole 22; the flow guide part 221 is an inclined surface. Because the peripheral wall of the flame-extinguishing hole 22 is provided with the flow guiding part 221, the flow guiding part 221 can play a role in guiding flow, and the linear movement of the air flow in the shell 10 is realized, so that the air in the shell 10 can rapidly enter the gap between the shell 10 and the body 21 from the flame-extinguishing hole 22, and the noise reduction effect is improved.
