In above-mentioned fixed automatic fire extinguisher, described gauge tap can be a kind of of temperature detect switch (TDS), infrared switch or cigarette control switch, or in them two kinds or three kind are through series connection or be formed in parallel.Utilize temperature detect switch (TDS), infrared switch or cigarette control switch, just can make temperature, infrared ray or the smoke condition of this extinguishing device, when reaching the setting degree, start automatically, realize the function of self-extinguishing according to used place.
In above-mentioned fixed automatic fire extinguisher, described inner casing is to be made of one deck foil.
In above-mentioned fixed automatic fire extinguisher, the aperture on the described shell is uniformly distributed in around the shell.
This automatic fire extinguisher at first is that gauge tap is connected when starting, and makes by control circuit to start the head energising; Then, by starting head the startup agent is started, act on the carminative, carminative produces gases at high pressure; At last, gases at high pressure enter in the inner chamber of shell, produce high pressure in the inner chamber, force that inner casing breaks, extinguishing chemical ejects from each aperture of shell, spill to the scene of a fire.
In above-mentioned fixed automatic fire extinguisher, also be provided with a startup pipe that inserts on the activation members on the described activation members, the inner that starts pipe is arranged in and starts agent, and activation members is stretched out in the outer end that starts pipe.Start pipe and be for this automatic fire extinguisher manually or the mode by flame ignition start and prepare.
In this automatic fire extinguisher, above-mentioned startup agent, carminative, startup head and startup pipe all have application in existing extinguishing device, belong to known technology, so be not described in detail in this.The inventive point of present patent application is automatic fire extinguisher improvement structurally.
Compared with prior art, the advantage of this automatic fire extinguisher is:
1, since in the enclosure wall be provided with inner casing, make the inner chamber of shell when not having fire alarm, be in sealing state, so can prolong the period of storage of extinguishing chemical, also prolonged the service life of this extinguishing device.
2, around shell, be uniform-distribution with aperture, extinguishing chemical can evenly be ejected on the scene of a fire; Simultaneously, the gases at high pressure that utilize carminative to produce eject extinguishing chemical in a short period of time, have improved the fire extinguishing effect, can fast and effeciently extinguish the blaze.
3, this automatic fire extinguisher is realized by gauge tap owing to can adopt multiple sniffer, and uses flexibly, so practical, automaticity is high.
