The blocking portion 422 is in contact with a side of the reservoir fixing member 13 away from the reservoir 20 with a gap, that is, there is a gap between the blocking portion 422 and the surface of the reservoir fixing member 13 away from the mounting plate 11b for the fire extinguishing agent to flow out.

The orthographic projections of the puncture portion 421 and the puncture hole 351 on the blocking portion 422 are located within the region of the blocking portion 422 , so that the blocking portion 422 can cover the puncture hole 351 and have a gap contact with the end of the reservoir fixing member 13 away from the reservoir 20 .

Please refer to FIG. 6 and FIG. 8 , FIG. 8 is an enlarged view of A in FIG. 6 . As shown in FIG. 6 and FIG. 8 , the fire extinguishing agent in the storage 20 flows in the direction indicated by the arrows in FIG. 6 and FIG. 8 , wherein, since the blocking portion 422 covers the puncture hole 351, when the seal 22 is punctured, the fire extinguishing agent released from the storage 20 flows out from the gap between the blocking portion 422 and the side of the storage fixing member 13 away from the storage 20 , which can reduce the flow rate of the fire extinguishing agent, thereby reducing the pressure difference between the accommodating chamber 50a and the outside, thereby protecting the fire extinguishing device 100. Since the pressure of the fire extinguishing agent in the storage 20 is relatively high, when the seal 22 is punctured, the fire extinguishing agent is instantly released at a very high flow rate, which is easy to damage the fire extinguishing device 100. By providing the blocking portion 422, the flow rate of the fire extinguishing agent can be reduced, thereby protecting the fire extinguishing device 100.

Please refer to Figures 4, 8 and 9, Figure 9 is another cross-sectional view of the fire extinguishing device 100 shown in Figure 4.
