The operation principle of the present invention is that:
Fig. 6 experiences the temperature of external environment to the glass marble into Fig. 9, explodes, since glass marble is fixed on cone
On seat, and disc spring being equipped between cone seat and spray core, disc spring generates certain elastic force, after glass marble explosion, due to the elastic force of disc spring,
Cone seat is popped up, while by disc spring, if there is O-ring in structure, O-ring is popped up together, the outlet of spray core is opened, thus will
The extinguishing chemical of interior of steel bottle is sprayed out of spray core and nozzle, to put out a fire.The principle and Fig. 6 of Figure 10 to Figure 13 is to Fig. 9's
Principle is identical, only increases heating film in the structure of Figure 10 to Figure 13 and knot is led in control, control heating film by pilot
Piece heats glass marble, to bring it about explosion.Fig. 6 is to being automatic shape to Fig. 9, i.e., it is equipped with glass marble and experiences external container
Temperature, to explode, and Figure 10 to Figure 13 be it is active, by the temperature of temperature sensor monitoring external container, and will
The temperature is transferred to control system, since control system control heating membrane heats glass marble, so as to cause the explosion of glass marble,
Temperature sensor 33 is fixed on nozzle body 7 by attachment base 34.
It as shown in Figure 18 and Figure 19, is the structural schematic diagram of diaphragm seal in the present invention.It includes steel cylinder 1, steel cylinder 1
Top is equipped with outlet 211, and outlet is sealed by diaphragm 212, and the outer sheath for exporting 211 is equipped with container valve body 202, container value
The top of body 202 is equipped with extinguishing chemical outlet 204, and the top of container valve body 202 is fixed with a fixing seat 207, inside fixing seat 207
Equipped with glass marble 209, the bottom of glass marble 209 is equipped with a power part 205, and the bottom of the power part 205 is taper, institute
Diaphragm can be punctured by stating power part 205, be inside the power part it is hollow, i.e., extinguishing chemical in steel cylinder can by power part from
Extinguishing chemical outlet outflow.
The power part 205 includes fixed part 206 and connecting rod 203, and the end of the connecting rod 203 is taper.
The fixed part 206 is sheathed on an interior of shell, and the power part can be slided relative to the shell.
A limit spring 208 is equipped between the power part and the shell, the power part passes through the limit spring
It is fixed on the top of the shell.
Be inside the fixed part and connecting rod it is hollow, i.e., the extinguishing chemical in steel cylinder can pass sequentially through fixed part and connection
Bar is exported from extinguishing chemical to flow out.
The difference of Figure 18 and Figure 19 is, further include in Figure 19 heating membrane 12 is equipped on the outside of glass marble, and it is described plus
Film 31 is heated by heating wires 32.The invention also includes a temperature sensor 33, the temperature sensor 33 is logical
Attachment base 34 is crossed to be fixed in fixing seat.
Working principle are as follows: logical ground diaphragm is sealed storage after perfluor hexanone liquid is injected into bottle body, and glass marble is by outer
It explodes after the high temperature on boundary, it, can be to dynamic when glass marble explosion time since power part is set to the downside of glass marble and adjacent
Power portion generates a motive force, so that propulsion power portion moves downward, since the bottom of power part is taper, power part is downward
When movement, diaphragm can be punctured, so that the extinguishing chemical of interior of steel bottle be released, is sprayed from nozzle, to put out a fire.
The diaphragm micropump type automatic fire extinguisher of Figure 18 is automatic shape, i.e., it is equipped with the temperature that glass marble experiences external container
Degree, to explode, and the automatic fire extinguisher in Figure 19 be it is active, by the temperature of temperature sensor monitoring external container
Degree, and the temperature is transferred to control system, since control system control heating membrane heats glass marble, so as to cause glass marble
Explosion.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
