[0074] When the fire extinguishing agent storage mechanism is in the working state, the striker 53 moves towards the bottle sealing member and pierces the bottle sealing member, so that the storage bottle 31 and the sleeve channel 511 are communicated, and the storage substance in the storage bottle 31 can enter the sleeve channel 511 and be discharged through the sleeve through hole 512; the discharge path is short, the discharge is smooth, the discharge amount is sufficient, the reliability is high, and the safety is high.

[0075] In view of the problem that the connection between the striker sleeve 51 and the storage bottle 31 is unreliable, the embodiment provides that the sleeve channel 511 comprises a first sleeve channel section 5111 and a second sleeve channel section 5112 which are arranged in sequence along the axial direction of the striker sleeve 51 and are communicated, and one end of the first sleeve channel section 5111 away from the second sleeve channel section 5112 is open;

[0078] Further, the inner diameter of the first sleeve channel segment 5111 is greater than the inner diameter of the second sleeve channel segment 5112; the open end of the first sleeve channel segment 5111 is formed with a first inverted taper surface 5114, and the end of the first sleeve channel segment 5111 close to the second sleeve channel segment 5112 is formed with a second inverted taper surface 5115; the end of the main body wall close to the bottle mouth wall abuts against the first inverted taper surface 5114, and the first inverted taper surface 5114 plays a limiting and guiding role on the main body wall; the bottle mouth abuts against the second inverted taper surface 5115, and the second inverted taper surface 5115 plays a limiting role on the bottle mouth.

[0079] Specifically, the inside of the striker 53 is formed with a striker channel 531, one end of the striker channel 531 is open and is in the shape of a sharp spike; the side wall of the striker 53 is formed with a striker through hole 532; the striker channel 531, the striker through hole 532, the sleeve channel 511 and the sleeve through hole 512 are sequentially communicated;

[0080] The striker through hole 532 is in a wavy structure or a sawtooth structure; preferably, the striker through hole 532 is in a sawtooth structure.

[0081] In view of the sealing problem between the sleeve channel 511 and the storage bottle 31, the embodiment proposes that the side wall of the first sleeve channel segment 5111 is formed with a sleeve sealing groove 5116, the sleeve sealing groove 5116 is located between the first inverted taper surface 5114 and the second inverted taper surface 5115 and is in an annular structure; a sleeve inner sealing ring is arranged in the sleeve sealing groove 5116, the sleeve inner sealing ring is arranged around the outside of the bottle mouth wall, and the sleeve inner sealing ring can seal the gap between the first sleeve channel segment 5111 and the bottle mouth wall.

[0082] In view of the problem that the striker 53 cannot slide in a certain direction in the sleeve channel 511, the embodiment proposes that the sleeve channel 511 further includes a third sleeve channel segment 5113, the third sleeve channel segment 5113 and the second sleeve channel segment 5112 are communicated, and the third sleeve channel segment 5113 and the second sleeve channel segment 5112 are coaxially arranged; the inner diameter of the third sleeve channel segment 5113 is smaller than the inner diameter of the second sleeve channel segment 5112;

[0084] The striker 53 has elasticity, and a maximum outer diameter of the striker 53 is greater than an inner diameter of the base mounting hole 5211; an end of the striker 53 away from the bottle mouth is embedded in the base mounting hole 5211, and the striker 53 can slide with the striker base 52.

[0085] Further, a side wall of the sleeve passage segment 5112 is formed with a sleeve through hole 512; an end of the first base segment 521 away from the second base segment 522 is formed with a tapered surface 5212, and a small diameter of the tapered surface 5212 is smaller than an inner diameter of the bottle mouth;

[0086] When the fire extinguishing device is in the working state, the tapered surface 5212 has a flow guiding effect and simultaneously increases a flow area between the sleeve passage 511 and the striker base 52; the storage substance in the storage bottle 31 enters the striker passage 531 and then enters the sleeve passage 511 through the striker through hole 532, and the storage substance enters the sleeve through hole 512 smoothly through the tapered surface.

[0087] In addition, the fire extinguishing agent storage mechanism further includes a trigger assembly 62, the trigger assembly 62 is arranged at an end of the striker sleeve 51 away from the storage bottle 31; the trigger assembly 62 includes a first trigger piece which is slidable;

[0088] When the fire extinguishing agent storage mechanism is in the non-working state, the first trigger piece is separated from the striker 53;

[0089] When the fire extinguishing agent storage mechanism is in the working state, the first trigger piece moves towards the striker 53 and drives the striker base 52 to slide along the sleeve passage 51, and then the striker 53 pierces the bottle sealing piece, and the storage bottle 31 can release the storage substance outward;

[0090] Specifically, the fire extinguishing agent storage mechanism includes a sliding seat 61, an inner portion of the sliding seat 61 is formed with a sliding channel 615; the first trigger piece is arranged in the sliding channel 615 in a slidable manner; the first trigger piece moves towards the striker 53 along the sliding channel 615 and drives the striker 53 to slide.

[0093] When the fire extinguishing agent storage mechanism is in the non-working state, the other end of the second trigger piece is limited in the second sliding channel end, and the elastic piece 63 stores energy;

[0094] When the fire extinguishing agent storage mechanism is in the working state, the elastic piece 63 releases the energy, the other end of the second trigger piece is separated from the second sliding channel end, and the first trigger piece drives the striker 53 to slide.

[0095] Specifically, the first trigger is a slider 623, and the second trigger is a slider 621.

[0096] In addition, the fire extinguishing agent storage mechanism also includes a heat sensing component 64, which is located at the end of the slide 61 away from the connector 41;

[0097] When the extinguishing agent storage mechanism is not in operation, the triggering component 62 is fixed by the contact action of the heat sensing component 64;

[0098] When the extinguishing agent storage mechanism is in operation, the heat sensing component 64 loses its contact function, and the triggering component 62 moves towards the firing pin and drives the firing pin 5 to puncture the bottle seal.

[0099] The triggering component 62 and the temperature sensing component 64 constitute the temperature-sensing triggering mechanism 6. Specifically, the temperature sensing component 64 has an inherent temperature and includes a fusible alloy component. The inherent temperature is the melting point of the fusible alloy component. The fusible alloy component can sense the ambient temperature, which is the temperature of the environment where the fire extinguishing device is located. When the ambient temperature is lower than the inherent temperature, the fire extinguishing agent storage mechanism is in a non-working state. When the ambient temperature is equal to or higher than the inherent temperature, the fire extinguishing agent storage mechanism is in a working state.
