Description
Technical field
The present invention relates to hand-held fire extinguisher and the technical field of extinguishing method structure, particularly a kind of hand-held fire extinguisher
And extinguishing method.
Background technology
Hot-gas sol fire extinguishing agent is a kind of pyrotechnic compound, and it is anti-that strong burning can occurs when discharging hot-gas sol fire extinguishing agent in it
Should, substantial amounts of heat is discharged, in order to avoid the generation of spot fire, generally use hot aerosol cooling agent is cooled down.Pass
The hand-held fire extinguisher of system includes outer barrel and inner cylinder, and inner cylinder is coaxially disposed in outer barrel, is provided with inner cylinder
Partition plate and lower clapboard, the powder column in inner cylinder are provided with below lower clapboard, being compressed between upper lower clapboard has hot aerosol
Cooling agent, the upper end of outer barrel are provided with Bearing score pipe.In use, powder column is lighted, the high temperature hot gas discharged after lighting is molten
Glue extinguishing chemical enters in the gap of hot aerosol cooling agent, and the hot-gas sol fire extinguishing agent after being cooled is sprayed from the spout of Bearing score pipe
Go out, so as to fulfill fire extinguishing.However, there are following defect for this fire extinguisher：（1）Inner cylinder is directly contacted with outer barrel, powder column combustion
Heat caused by burning will certainly pass to inner cylinder, then pass to outer barrel by inner cylinder, certainly will cause portion of the handle temperature
Rise, scalds operating personnel, this outer barrel is also possible to be burned out.（2）When powder column burns, in inner cylinder air pressure raise rapidly, if
The spout of Bearing score pipe blocks, compression shock Bearing score pipe, and Bearing score pipe will be caused to separate with outer barrel and fly out at a high speed and wound people, very
It is dangerous.（3）Hot aerosol cooling agent is pressed between lower clapboard, but has gap between hot aerosol cooling agent, works as warp
Cross after rocking, hot aerosol cooling agent is loose, causes hot aerosol cooling agent impact inner cylinder body wall and produces the sound, while hot gas
Colloidal sol cooling agent can be also covered on powder column through lower clapboard, cause powder column not burn.
The content of the invention
A kind of the shortcomings that it is an object of the invention to overcome the prior art, there is provided compact-sized, safe and reliable, operation letter
Just, the hand-held fire extinguisher and extinguishing method of good extinguishing effect.
The purpose of the present invention is achieved through the following technical solutions：A kind of hand-held fire extinguisher, it includes suitable from top to bottom

Under be resisted against on the large end face of taper, powder column is provided with rubber bag sheathing, reaction chamber is offered at the top of powder column, react
Intracavitary is provided with igniter.
Three big straight slots are uniformly provided with the annular table.
Three connector C are uniformly installed with the Bearing score pipe.
The length of the connector A is more than the length of connector B, and the length of connector C is more than the length of connector A.
Sealing ring is provided between the bottom plate and casing of the Bearing score pipe.
Piezoelectric heads are provided with the handle, piezoelectric heads are connected through cable-through hole and with igniter through conducting wire.
Pneumatic button, start button and the opposed setting of piezoelectric heads are provided with the outside of the handle.
The extinguishing method of the hand-held fire extinguisher, it comprises the following steps：
S1, operating personnel hold handle, and the outlet of Bearing score pipe is pressed downward start button, start button touching towards burning things which may cause a fire disaster
Piezoelectric heads turn it on so that igniter discharges；
S2, igniter light powder column, and powder column discharges high temperature hot gas aerosol extinguishing agent when burning, and high temperature hot gas aerosol extinguishing agent exists
Venthole under air pressure through lower clapboard enters in the gap hot aerosol cooling agent, and hot aerosol cooling agent is warmed with high
