Referring to fig. 1, an embodiment of the present invention provides a non-pressure storage type fire extinguisher, which includes a housing 10, a fire extinguishing agent 20 and an actuating mechanism 30.

The housing 10 has a housing chamber 11 and a fire outlet 12, and the fire extinguishing agent 20 is housed in the housing chamber 11. The actuating mechanism 30 includes an inner shell 31, a gas generant 32, and a fuse 33. The inner shell 31 is installed in the accommodating cavity 11 and has a cavity 311 and a lead-out hole 312 communicating the cavity 311 and the accommodating cavity 11. The gas generating agent 32 is contained in the cavity 311, one end of the blasting fuse 33 is positioned in the cavity 311, and the other end of the blasting fuse 33 passes through the outlet hole 312, the containing cavity 11 and the eruption port 12 in sequence and is led out of the containing cavity 11. Alternatively, the blasting fuse 33 may be a heat-sensitive wire.

When a fire breaks out, the high temperature generated by the fire ignites the fuse 33, the fuse 33 burns into the cavity 311 of the inner shell 31, and the gas generating agent 32 in the cavity 311 is started, so that the gas generating agent 32 can rapidly generate a large amount of gas. When the air pressure in the cavity 311 reaches a certain value, the air pressure breaks through the inner shell 31, and the fire extinguisher in the accommodating cavity 11 is sprayed out from the spraying opening 12, so that the fire extinguishment is realized.

So, the fire cord 33 is drawn forth from eruption mouth 12 in the non-pressure storage formula fire extinguisher of this application, has avoided taking place from the phenomenon that the gas that inner shell 31 directly drawn forth and produced leaks, is favorable to improving the eruption dynamics, ensures fire control effect.

In the embodiment of the present invention, the non-pressure storage fire extinguisher further comprises a first pressure releasing membrane 13 hermetically covering the fire nozzle 12, wherein the first pressure releasing membrane 13 is provided with a through hole for the fire fuse 33 to pass through. So, first pressure release diaphragm 13 plays the purpose of sealed eruption mouth 12, breaks through inner shell 31 and gets into holding chamber 11 when producing a large amount of gases behind gas agent 32 starts for holding chamber 11 is in high-pressure state, makes first pressure release diaphragm 13 break, thereby fire extinguishing agent 20 is followed this eruption mouth 12 blowout, and then puts out a fire. Alternatively, the first pressure release film may be an aluminum film or the like, as long as it can be ruptured by the gas pressure generated by the gas generating agent 32, and is not limited thereto. The through-hole may be sealed with a sealant to prevent the fire extinguishing agent 20 from leaking out of the through-hole in the absence of a fire.

Referring to fig. 2, in the embodiment, the starting mechanism 30 further includes a protection tube 34, one end of the protection tube 34 is inserted through the exit hole 312 of the inner shell 31, and the other end of the protection tube 34 is inserted through the through hole of the first pressure-releasing membrane 13. The blasting fuse 33 is led out of the accommodating cavity 11 from the cavity 311 through the protective tube 34. Thus, the protection pipe 34 is used for protecting the fire guiding rope 33, and the fire extinguishing agent 20 is prevented from directly contacting the fire guiding rope 33 to influence the ignition of the fire guiding rope 33. Alternatively, the protective tube 34 may be a glass fiber tube. Of course, in other embodiments, the shielding tube 34 may be made of other materials, which is not limited herein.

In a specific embodiment, the gap between the shielding tube 34 and the inner wall of the exit hole 312 is sealed by a sealant, so as to prevent the fire extinguishing agent 20 from entering the cavity 311 from the gap between the shielding tube 34 and the inner wall of the exit hole 312, and thus the gas generating agent 32 is not effective.

Further, the gap between the protection tube 34 and the through-hole is sealed with a sealant, thereby preventing the fire extinguishing agent 20 from leaking from the gap between the protection tube 34 and the through-hole.

In one embodiment, the activation mechanism 30 further includes an electrical initiator (not shown) and an electrical activation wire (not shown). The electric initiator is arranged in the cavity 311, one end of the electric starting line is connected with the electric initiator, and the other end of the electric starting line passes through the protective tube 34 and is led out of the accommodating cavity 11 for being connected with an external controller. In this manner, in the event of a fire, the external controller controls the ignition of the electrical initiator via the electrical activation line, thereby activating the gas generant 32 within the chamber.

Alternatively, the electrical initiator may be an electrical firing head.

In one embodiment, the actuating mechanism 30 further comprises a temperature sensor (not shown) and a feedback line (not shown), the temperature sensor being disposed in the inner cavity for detecting the temperature in the cavity 311. One end of the feedback line is connected to the temperature sensor, and the other end of the feedback line passes through the protective tube 34 and is led out of the accommodating cavity 11 for being connected with an external controller. Therefore, when the gas generating agent 32 is started, a large amount of gas is generated and simultaneously a large amount of heat is generated, the temperature sensor detects the temperature rise and transmits a temperature rise signal to the external controller through the feedback line, and the external controller judges that the non-pressure storage type fire extinguisher is started according to the temperature rise signal.

In the embodiment of the present invention, when the air pressure in the cavity 311 reaches a preset value, the inner shell 31 is ruptured, so that the gas generated by the gas generating agent 32 enters the accommodating cavity 11, and the fire extinguishing agent 20 in the accommodating cavity 11 is sprayed out from the spraying opening 12, so as to extinguish a fire. Further, inner shell 31 may be made of a plastic material, which may be easily broken when cavity 311 is under high pressure. It should be noted that the preset value can be set according to specific situations, and is not limited herein.

In other embodiments, the inner shell 31 is provided with a mounting hole for communicating the cavity 311 and the accommodating cavity 11, and the mounting hole is provided with a one-way valve, the one-way valve is communicated from the cavity 311 to the accommodating cavity 11, and is stopped from the accommodating cavity 11 to the cavity 311, so that a large amount of gas generated after the gas generating agent 32 is started can enter the accommodating cavity 11 from the one-way valve, and the fire extinguishing agent 20 is sprayed out from the spraying opening 12. Moreover, because of the one-way valve, the fire extinguishing agent 20 (volatilized into a gaseous state) cannot enter the cavity 311 through the one-way valve. Of course, the mounting hole may include a plurality of mounting holes, and each mounting hole is provided with a one-way valve, so that gas generated by the gas generating agent 32 can rapidly enter the accommodating cavity 11.

In other embodiments, the inner housing 31 defines a pressure relief hole communicating the cavity 311 and the accommodating cavity 11, and the actuating mechanism 30 further includes a second pressure relief diaphragm hermetically covering the pressure relief hole. Thus, when the fire extinguishing apparatus is not started, the second pressure relief diaphragm is used for sealing the pressure relief hole, so that the fire extinguishing agent 20 is prevented from entering the cavity 311 from the pressure relief hole. When the fire extinguishing agent is started, the gas generating agent 32 generates a large amount of gas, so that the second pressure relief diaphragm is broken, the gas can enter the accommodating cavity 11 from the pressure relief hole, and the fire extinguishing agent 20 in the accommodating cavity 11 is pushed to be sprayed out from the spraying opening 12 for fire extinguishing. Alternatively, an aluminum film may be used for the second pressure relief diaphragm.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
