DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] Hereinafter, an explanation on a small space fire extinguisher according to the present invention will be given briefly.

[0027] A small space fire extinguisher according to the present invention is installed in a small space to which it is hard for a person to access or where it is difficult to check whether a fire breaks out and is configured to allow a tube to burst if a fire occurs, so that a fire extinguishing agent such as a fire extinguishing liquid or gas, which is accommodated in the tube, spouts and scatters quickly to achieve initial fire suppression. To allow the fire extinguishing agent to be kept accommodated well in the tube, in this case, both sides of the tube are sealed by means of blocking members and coupling members, and if a fire breaks out, accordingly, the fire can be initially suppressed with the fire extinguishing agent stored in the tube.

[0028] Now, the small space fire extinguisher according to the present invention will be explained in detail with reference to the attached drawings.

[0029] As shown in FIGS. 1 to 4, the small space fire extinguisher 100 according to the present invention includes a tube 110, blocking members 120, packing members 130, coupling members 140, and blocking members 150.

[0030] The tube 110 is open from one side thereof to the other side thereof and is made of a synthetic resin so that a portion thereof bursts by the heat generated when a fire occurs to allow a fire extinguishing agent accommodated in the tube 110 to spout.

[0031] The blocking members 120 are cylindrical and coupled to both sides of the tube 110 to prevent the fire extinguishing agent accommodated in the tube 110 from leaking to the outside.

[0032] Each blocking member 120 includes a blocking member body 121 inserted into one side end or the other side end of the tube 110, a coupling recess 122 formed on the center of the blocking member body 121 and coupled to the corresponding coupling member 140 fitted to the outer peripheral surface of the tube 110 to allow the coupling member 140 to be fixed to the tube 110 by means of a compression device so that the fire extinguishing agent can be prevented from leaking to the outside, and an installation groove 123 formed at the center of the coupling recess 122 of the blocking member body 121.

[0033] Further, the packing members 130 are fitted to the installation grooves 123 formed on the coupling grooves 122 of the blocking member bodies 121 to prevent the fire extinguishing agent from leaking to the spaces between the tube 110 and the blocking members 150 through the coupling members 140 fitted to the tube 110 by means of compression.

[0034] The coupling members 140 are located on the outer peripheral surface of the tube 110, in the state where the packing members 130 are fitted to the installation grooves 123 of the blocking member bodies 121, and then compressed thereagainst by means of the compression device.

[0035] Desirably, each coupling member 140 has the shape of a ring whose diameter is larger than an outer diameter of the tube 110.

[0036] Each blocking member 150 has a “⊃”-shaped section open on one side thereof to form a space at the interior thereof, and in a state where the blocking members 120 to which the packing members 130 are fitted are disposed inside the tube 110, accordingly, the blocking members 150 are fitted to both side ends of the tube 110 to prevent the coupling members 140 compressedly fixed to the outer peripheral surface of the tube 110 from being exposed to the outside.

[0037] Under the above-mentioned configuration, the small space fire extinguisher 100 according to the present invention is fixed, in a small space like a distribution board 10 in which it is hard to install fire detecting or extinguishing equipment such as a fire detector, sprinkler, and the like, to the inner surface of the distribution board 10 by means of a fixing holder, and otherwise, the small space fire extinguisher 100 is fixedly suspended in the air by means of a wire with a hook or latch. Accordingly, the small space fire extinguisher 100 can be used immediately when a fire breaks out.

[0038] Referring now to the coupling process of the small space fire extinguisher 100, the packing member 130 is fitted to the installation groove 123 of the blocking member 120, and next, the blocking member 120 is inserted into one side end of the tube 110. After that, the coupling member 140 is located on the outer peripheral surface of the tube 110 at which the packing member 130 is disposed and then compressed against the tube 110 by means of the compression device, so that the blocking member 120 is fixed to the inside of the tube 110.

[0039] In the state where the blocking member 120 and the coupling member 140 are installed on one side of the tube 110, the fire extinguishing agent is injected into the other side of the tube 110, and after that, the blocking member 120 to which the packing member 130 is fitted is inserted into the other side end of the tube 110. Next, the coupling member 140 is located on the outer peripheral surface of the tube 110 so that the coupling member 140 is compressedly fixed to the coupling recess 122 at which the packing member 130 is disposed.

[0040] The coupling member 140 is fitted to the outer peripheral surface of the tube 110 and then compressed against the tube 110 by means of the compression device, so that the blocking member 120 is fixed to the inside of the tube 110.

[0041] The blocking members 120 fixed to the inside of the tube 110 can prevent the fire extinguishing agent from leaking to the spaces between the tube 110 and the blocking members 120 by means of the packing members 130.

[0042] After the above-mentioned coupling process, the small space fire extinguisher 100 according to the present invention is installed in a small space like a distribution board 10 in which it is hard to install fire detecting or extinguishing equipment for initial fire suppression if a fire breaks out, such as a fire detector, sprinkler, and the like, so that the initial fire suppression can be achieved.

[0043] For example, the small space fire extinguisher 100 on the distribution board 10 may be fixed to a wall surface or a ceiling of the distribution board 10, and otherwise, the small space fire extinguisher 100 may be suspended in the air.

[0044] If the small space fire extinguisher 100 is fixed to the distribution board 10, at least two or more fixing holders (not shown) are installed on the ceiling or wall surface of the inner side of the distribution board 10, and the fixing holders are fixedly located on portions of the tube 110 where the blocking members 150 are fitted, so that if a fire breaks out, the tube 110 bursts to inject the fire extinguishing agent stored therein, thereby performing initial fire suppression.

[0045] If the small space fire extinguisher 100 is suspended in the air inside the distribution board 10, a wire is provided to allow one side to be fixed to the ceiling of the inner side of the distribution board 10 through a screw and to mount a hook or latch on the other side thereof, so that the tube 110 is fixedly suspended in the air on the inner surface of the distribution board 10.

[0046] If a fire breaks out in the state where the small space fire extinguisher 100 is installed in a small space like the distribution board 10, the tube 110 bursts by the heat generated from the fire, and simultaneously, the fire extinguishing agent stored in the tube 110 at a given pressure spouts to block the contact of air with a portion where the fire breaks out, thereby performing initial fire suppression.

[0047] As mentioned above, the small space fire extinguisher 100 according to the present invention is installed in small spaces, such as the interiors of home appliances, distribution boards, and the like, where it is hard to easily recognize the occurrence of fires, and if a fire breaks out, the tube 110 bursts to allow the fire extinguishing agent stored therein to spout and scatter quickly, thereby performing initial fire suppression to prevent the fire from spreading and to achieve fire suppression with ease.

[0048] Further, the small space fire extinguisher 100 according to the present invention is adjusted in size according to the size of the small space where it is installed.

[0049] In addition, the small space fire extinguisher 100 according to the present invention is fixed to the inner surface of the small space or suspended in the small space, and accordingly, the small space fire extinguisher 100 can be freely installed according to the shape of the small space, so that if a fire breaks out, the small space fire extinguisher 100 can be used immediately to achieve initial fire suppression. Further, the tube 110 is sealed firmly on both side ends thereof, thereby ensuring the stability in installation work.
