Technical field

The utility model relates to extinguishing device, particularly a kind of have confession spray power from jetting fire extinguisher.

Background technology

At present, be dispersed throughout shop, China town and country, market, office, factories and miness ... various places everywhere know traditional common fire extinguisher of seeing, the overwhelming majority is that (a kind of fire extinguisher that storage is pressed that do not have appearred to pressure storage type in past attempts, it is to deposit in separately the container with bronsted lowry acids and bases bronsted lowry, not having pressure at ordinary times deposits, to wait make Acid-Base when using the two react, and produces pressure and put out a fire.But, its reactant eliminates stopping production already because of having severe corrosive.), no matter be the MJPZ fire extinguisher, still various dry powder extinguishers, they all are the power that relies on pressed gas (all the being employing nitrogen usually) spray fire extinguishing agent when being used as putting out a fire that injects in advance in the fire extinguisher chamber.When using, the handle valve is opened, and when being stored in the compressed gas release in the jar, just ordering about the extinguishing chemical that is stored in simultaneously in the jar and also ejects, and puts out a fire.Yet, because this fire extinguisher is that long-term area pressure is deposited, very easily produces and leak (gas leakage, pressure release), just therefore pressure (power) is exhausted.In when urgent need in case the condition of a fire takes place, but because insufficient pressure and can't spray fire extinguishing agent, thereby cause affecting adversely the fire fighting good opportunity, the accident that fire spread is enlarged takes place repeatedly.That is to say that the large-scale popularization of this fire extinguisher and use and a large amount of generation of depositing in fact, not only do not have when the time comes and help in the fire extinguishing disaster relief, cause the illusion of " safety " on the contrary to people, decline in alertness, future trouble is serious.

For fear of the continuous recurrence of this phenomenon, China's " elimination " expressly provides, must carry out pneumatic compression termly to this class fire extinguisher, and to guarantee in use can have sufficient pressure and finish the fire extinguishing task, the side is unlikely and affects the fire extinguishing good opportunity adversely.But because this class fire extinguisher has been produced a century nearly, nowadays the generation storage in the society is quite huge again, for numerous fire extinguisher like this, carries out inflation pressurization termly so continually, has become a kind of very numerous superfluous work already.So for numerous fire extinguisher owners, they also are that hard to bear its is tired of mostly, just abandoned this pressurized operation of constantly inflating then termly loaded down with trivial detailsly.So, caused this type of a large amount of fire extinguisher again, much less in fact all mostly become inefficacys, become suspension and deposit, deposited and the thing of useless " furnishings " as depositing this life! More irritating is to have had this " furnishings ", people just to think and can sleep without any anxiety, and grows paralysis, imaginary safety.Therefore often affect the fire extinguishing good opportunity adversely, cause fire spread to enlarge! So not only caused in fact huge waste, but also constituted the general disaster hidden-trouble of huge social goods and materials.

Summary of the invention

The purpose of this utility model is that design a kind ofly need not to inflate pressurization, is in not have and stores up that pressure condition is deposited, the autoginious pressure self-spraying fire-extinguishing device of Maintenance free for a long time.

In order to achieve the above object, the utility model adopts following technical solution, a kind of autoginious pressure self-spraying fire-extinguishing device, comprises fire extinguisher, it is characterized in that being provided with on fire extinguisher spontaneous depressor.

Owing to be provided with spontaneous depressor, in case breaking out of fire, extinguishing device must the time spent, starts the spontaneous depressor that is attached on the extinguishing device and just can produce one apace be enough to finish gas pressure that extinguishing chemical sprays as power in less than one second time, puts out a fire.Therefore it need not prior injection pressure gas, being in stress-free state at ordinary times deposits, as Bottle ﹠ Can vessel commonly used in our life, fundamentally just eliminated the sorrow of leakage, can place chronically, thereby also fundamentally exempted need termly inflation continually to pressurize loaded down with trivial details, need not frequent maintenance.
