It is fixedly connected, pullover 42 is pushed into offset with the limit end 46 far from small of the stock hand 11 by the active force of the first spring 44；The drawing
One end of handle 45 is fixed on the pullover 42, and the other end extends to except gun housing 1, referring to Fig. 1, Fig. 2, Fig. 5 and Fig. 6.
The sealing 31 of easily tearing that the top of the gun barrel 2 corresponds to the extinguishing agent storage box 3 is provided with fluting 21.
The arrival end of the nozzle 5 is connected to the outlet end of the gun barrel 2, and the outlet end of nozzle 5 is provided with several spray orifices
51, the equidistantly distributed annular in shape on nozzle 5 of spray orifice 51.
The gas tank 6 stores the carbon dioxide gas of compression, the arrival end of the outlet end of gas tank 6 and the gun barrel 2
Connection, and the outlet end of gas tank 6 is closed by a diaphragm 61.
The sharp portion 71 is located near the outside of the diaphragm 61, and the tip of sharp portion 71 is directed at 6 film of gas tank
The center of piece 61, the tail end of sharp portion 71 and bottom end are both secured on a L shape seat board 72.
The trigger 81 keeps linking by mechanical linkage component 9 and the sharp portion 71, the mechanical linkage group
Part 9 drives sharp portion 71 to be enough to poke on diaphragm 61 to the mobile extreme position in 61 direction of diaphragm, the tail portion of trigger 81 and second
One end of spring 82 connects, and the other end of second spring 82 is then fixed on spring base 83, mechanical as a result, when cocking 81
Linkage unit 9 will drive the diaphragm 61 that sharp portion 71 pokes gas tank 6, and after loosing one's grip, trigger 81 can be in the effect of second spring 82
Lower self-return.
Specifically, the mechanical linkage component 9 includes first gear 91, second gear 92, is located on the trigger 81
Side is in horizontally disposed first bar shaped tooth 93 and is located at below the L shape seat board 72 in horizontally disposed second bar shaped tooth 94；
The bottom of the first gear 91 is engaged with the first bar shaped tooth 93, and front side is engaged with second gear 92, the second gear 92
It is engaged with the second bar shaped tooth 94 upside；Wherein, the outer diameter of the first gear 91 is greater than the outer diameter of second gear 92, greatly
It causes to be 2 times of 92 outer diameter of second gear, referring to Fig. 3.The purpose of twice 92 outer diameter of second gear of 91 outer diameter of first gear is:
The biggish shift motion of sharp portion 71 can be driven by the smaller shift motion of trigger 81.
Preferably, the gas tank 6 is connect by silk thread mouth with the gun barrel 2, and screwed connection facilitates gas tank 6 more
It changes, is backed out after being finished i.e. replaceable new.The front end of gas tank 6 is embedded in the tail portion of the gun housing 1, and the tail end of gas tank 6 extends outwardly
Gun housing 1 out.
Further, the tearing notch knife 41 includes the bore spine portion 411 being located above and underlying blade portion 412,

It is equipped with step surface 32, extinguishing agent storage box 3 is embedded in by the step surface 32 and is stuck in the top of the gun housing 1, wherein extinguishing chemical
Storage Box 3 can be connect by the snap-in structure for common lockable/can unlock with gun housing 1.Described easily tears sealing 31 by putting out a fire
The bottom of agent Storage Box 3 extends to the corner of the step surface 32.When left direction is mobile into Fig. 1 for tearing notch knife 41, cone
Thorn portion 411 can first on right side, vertical easily tearing stabs out an openning, when then proceeding to be moved to the left, blade portion 412 in sealing 31
The sealing 31 of easily tearing of bottom will be cut into out from right to left a slit for starting point by the openning.
Preferably, the sharp portion 71 is located in the gun barrel 2, and the transverse slat of 72 bottom of L shape seat board, which slides, to be connected
It is connected in the sliding slot 22 of 2 arrival end bottom of gun barrel, referring to Fig. 3.Wherein, on the riser of 72 side of sharp portion 71 and L shape seat board
It is arranged by several holes, is passed through with the air-flow that air feed tank 6 releases, avoids the flowing for hindering air-flow.
The extinguishing chemical stored in the extinguishing agent storage box 3 is dry powder, or may also be dry ice.
It should be noted: when design, referring to Fig. 5, pullover 42 and the design of guide rod 43 can easily torn the side below sealing 31
Side avoids the whereabouts for hindering extinguishing chemical.
About use of the invention:
Place one or more fire extinguishers of the invention and several standby in the place that can conveniently take under lab in advance
Gas tank 6 and extinguishing agent storage box 3.When carrying out chemical experiment, if flare is originally not when test operation is improper and on fire
Can be too big, it can be put out using the present invention.In use, pull handle 45 is pulled i.e. available tear to 11 direction of small of the stock hand with hand
The sealing 31 of easily tearing of 3 bottom of extinguishing agent storage box is torn and is cut open by mouthful knife 41, falls into the extinguishing chemical in box in gun barrel 2, later will
Nozzle 5 is directed at flare, and cocking 81 drives sharp portion 71 to poke the diaphragm 61 of gas tank 6, makes gas by mechanical linkage component 9
High-pressure carbon dioxide gas abrupt release in tank 6 pushes the extinguishing chemical in gun barrel 2 to go out and by the spray orifice of nozzle 5 51 in mist
Shape sprays, and can extinguish the blaze.After use, the gas tank 6 and extinguishing agent storage box 3 being finished are removed, replace with new gas tank 6 and is gone out
Fiery agent Storage Box 3 can reuse.
When chemical experiment, by test operation it is improper fire, flare is originally all not too large, according to common fire extinguishing
Cylinder fire extinguishing, wastes one's talent on a petty job a little, extinguishing chemical consumption is more, and higher cost is unsuitable.And gun shaped of the invention is used to put out a fire
Device can ideally substitute common fire extinguisher, have the advantages that it is used as needed, easy to operate, and spray extinguishing chemical amount
It is moderate, it is able to satisfy putting out for general small flare, after first use, the gas tank 6 and extinguishing agent storage box 3 more renewed can make again
With.
