[0100] The temperature-sensing trigger mechanism 6 is provided with a non-working state and a working state. The non-working state of the temperature-sensing trigger mechanism 6 corresponds to the non-working state of the fire extinguishing agent generating mechanism, and the working state of the temperature-sensing trigger mechanism 6 corresponds to the working state of the fire extinguishing agent generating mechanism.

[0101] When the temperature-sensing trigger mechanism 6 is in a non-working state, the trigger assembly 62 is fixed to one end of the slide 61, and the elastic member 63 stores energy;

[0102] When the temperature-sensing trigger mechanism 6 is in working state, the elastic member 63 releases energy and drives the trigger assembly 62 to slide along the slideway toward the striker 53 , and the trigger assembly 62 pierces the bottle seal with the striker 53 .

[0103] In order to solve the problem that the fire extinguishing device cannot sense the occurrence of fire in time, the present embodiment proposes that the temperature-sensing trigger mechanism 6 further includes a temperature-sensing mechanism 64, and the temperature-sensing mechanism 64 is arranged at one end of the trigger component 62 away from the connecting member 41;

[0104] When the temperature sensing trigger mechanism 6 is in a non-working state, the trigger assembly 62 is fixed under the abutment of the temperature sensing mechanism 64;

[0105] When the temperature-sensing trigger mechanism 6 is in the working state, the temperature-sensing mechanism 64 loses its abutment effect, and the trigger assembly 62 moves toward the direction close to the striker and drives the striker 5 to pierce the bottle seal;

[0107] In view of the problem that the shell 1 needs to discharge the fire extinguishing agent, the present embodiment proposes that the shell wall of the shell 1 is also formed with a shell discharge port 142, and the shell discharge port 142 is located at the bottom of the shell 1; the fire extinguishing device includes a nozzle assembly 2, and the nozzle assembly 2 is arranged at the shell discharge port 142, and the nozzle assembly 2 includes a nozzle seat 21, a nozzle nut 22 and a nozzle 23, the nozzle seat 21 is penetrated in the shell discharge port 142, one end of the nozzle seat 21 is located in the shell cavity 13 and abuts against the side wall of the shell discharge port 142; the nozzle nut 22 and the nozzle seat 21 are connected by threads, and the nozzle nut 22 is located on the outside of the shell cavity 13, so that the nozzle seat 21 is fixed on the lower shell 12; the nozzle 23 is arranged at the other axial end of the nozzle seat 21; a discharge channel is connected between the shell discharge port 142 and the nozzle 23, and a plugging member is arranged in the discharge channel; specifically, the shell discharge port 142 is provided with at least one, and the plugging member is a sealing film;

[0108] When the fire extinguishing agent generating mechanism is in a non-operating state, the blocking member closes the discharge passage, and the nozzle 23 and the housing cavity 13 are not connected;

[0109] When the fire extinguishing agent generating mechanism is in working state, the blocking member opens the discharge passage, the nozzle 23 is connected with the shell cavity 13, and the nozzle 23 can spray out the fire extinguishing agent.

[0110] Specifically, at least one shell discharge port 142 is provided, and a sealing member is provided on the nozzle 23, which is a nozzle sealing film; when the fire extinguishing agent generating mechanism is in a non-working state, the nozzle sealing film closes the nozzle 23; when the fire extinguishing agent generating mechanism is in a working state, the nozzle sealing film ruptures under the pressure of the fire extinguishing agent in the shell cavity 13.

[0111] In summary, the fire extinguishing device is provided with a non-working state and a working state. The non-working state of the fire extinguishing device corresponds to the non-working state of the fire extinguishing agent generating mechanism and the non-working state of the temperature sensing trigger mechanism 6. The working state of the fire extinguishing device corresponds to the working state of the fire extinguishing agent generating mechanism and the working state of the temperature sensing trigger mechanism 6.

[0112] When the fire extinguishing device is in a non-working state, the blocking member closes the discharge channel, the nozzle 23 and the shell cavity 13 are not connected; the bottle seal seals the bottle mouth, the storage bottle 31 and the shell cavity 13 are not connected; under the abutment of the temperature sensing mechanism 64, the trigger assembly 62 is fixed to one end of the slide 61, the elastic member 63 stores energy, and the striker 53 is away from the bottle seal; the pressure in the shell cavity is normal pressure, and there is no need to regularly detect the pressure in the shell cavity, which is reliable and has a long service life;

[0113] When the fire extinguishing device is in working state, the blocking part opens the discharge channel, and the nozzle 23 is connected with the shell cavity 13; the temperature sensing mechanism 64 loses its abutment effect, the trigger assembly 62 moves in the direction close to the striker and drives the striker 5 to pierce the bottle seal to open the bottle mouth; the storage bottle 31 and the shell cavity 13 are connected through the sleeve channel 511, the sleeve through hole 512, the connector channel 414 and the connector through hole 4113; the liquefied carbon oxides in the storage bottle 31 are discharged and expanded into gaseous carbon oxides, and the gaseous carbon oxides enter the shell cavity 13 through the sleeve channel 511, the sleeve through hole 512, the connector channel 414 and the connector through hole 4113 to mix with potassium salt and water to generate a fire extinguishing agent containing bicarbonate; the fire extinguishing agent is sprayed out through the nozzle 23 to extinguish the fire; the pressure required for the fire extinguishing agent to be sprayed is sufficient, the fire can be extinguished in time, and the fire extinguishing effect is obvious.
