The pin coupling 12 and 22 may be formed in such a way that the rupture pin 12 protruding from the main body 10 is inserted into the pin hole 22 drilled into the lid 20. The bursting pin 12 is configured to withstand the pressure of the extinguishing agent compressed and filled in the main body 10 for a predetermined time (5 seconds to 60 seconds), and has a strength that automatically ruptures.

The first safety piece 30 is a means for preventing the rupture of the rupture pin 12 by suppressing the opening of the lid 20 due to the pressure of the extinguishing agent in the main body 10. It is made of a shape, both ends of the inner surface is made of a configuration that is elastically tightly coupled to the upper surface of the lid 20 and the bottom of the main body 10, respectively.

At this time, the fitting protrusions 36 and 36a are respectively protruded from the inner side surfaces of both ends of the first safety piece 30, and the upper surface and the main body of the lid 20 corresponding to the fitting protrusions 36 and 36a. By forming fitting grooves 16 and 26 on the bottom surface of the cylinder 10, the first safety piece 30 is formed by coupling between the fitting protrusions 36 and 36a and the fitting grooves 16 and 26, respectively. It would be desirable to configure so that the combined state of the can be maintained stably.

At this time, when the first safety piece 30 is detached, the bursting pin 12 withstands the extinguishing agent pressure inside the main body 10 for several seconds to several tens of seconds by the strength of the bursting pin 12, thereby throwing the fire extinguisher While flying to the point of fire, the extinguishing agent is suppressed and falls to the point of fire only after the rupture pin 12 is ruptured and the lid 20 is opened, thereby extinguishing the internal extinguishing agent. It will also be able to fight down efficiently.

On the other hand, it is preferable that the lid 20 is configured to open only a certain angle from the main body 10 to form a narrow ejection passage, in this configuration, the extinguishing agent inside the main body 10 is a narrow ejection passage By being strongly ejected through, the internal pressure of the main body 10 is changed irregularly while the extinguishing agent is ejected, and thus the main body 10 is rotated as if splashing irregularly in all directions to eject the extinguishing agent, thereby causing the surrounding fire to burn out. You will have the advantage of being able to fight effectively.

This configuration, as shown, may be achieved by constructing the rotation inhibiting jaw 14a and the stopper inclined surface 24a at the hinge coupling 14 and 24 portions of the main barrel and the lid, respectively. In this configuration, when the lid 20 is opened, as shown in the enlarged view of FIG. 3, after the lid 20 is rotated by an angle, the stopper inclined surface 24a of the lid is rotated in the main body. It is caught by the restraining jaw 14a, and further rotation is suppressed, so that the opening degree of the lid 20 can be regulated.

In addition, the throwing fire extinguisher according to the present invention, in addition to the above-described configuration, a pair of separation wall plate 40, 45, opening and closing plate 50, rotary knob 55, two reactants and piston 60 It may be configured to include more.

The separating wall plates 40 and 45 are plate members fixed in a vertical direction in order to divide the inner lower part of the main body 10 into the center from the opposite inner wall surfaces of the main body 10 facing each other. At this time, the opening and closing passage is formed between the space divided into two by the separating wall plate (40, 45).

The opening and closing passage may include a space formed between end portions of each of the separating wall plates 40 and 45 and / or holes 40a and 45a drilled into each of the separating wall plates 40 and 45. There will be.

The opening and closing plate 50 is vertically disposed between the separating wall plates 40 and 45 so as to close the opening and closing passage, and the rotary knob 55 extending downward from the center of the bottom surface of the opening and closing plate 50. Is installed to penetrate through the bottom surface of the main body 10, the rotating plate 55 is rotated by the opening and closing plate 50 is configured to open the opening and closing passage.

On the surface of each of the separating wall plates 40 and 45 in close contact with the opening and closing plate 50, the packing plates 80 and 85 for preventing leakage are attached to each other so that the divided spaces are intimately separated from each other. something to do. Instead of the packing plates 80 and 85, the packing plate is attached to the surface of the opening and closing plate 50 in close contact with the separating wall plates 40 and 45, or the separating wall plates 40 and 45 in close contact with each other. Of course, the configuration for attaching the packing plate on all surfaces of the opening and closing plate 50 can be applied.

In the space divided by the separating wall plates 40 and 45 and the opening / closing plate 50, two reactants each having a property of rapidly expanding and causing a chemical reaction when mixed with each other are filled. As the two reactants, an aqueous solution of one of ammonium salt (NH 4 Cl aqueous solution), sodium carbonate (Na 2 CO 3 aqueous solution), potassium salt (K 2 CO 3 aqueous solution), and sodium carbonate monohydrate salt (NaHCO 3) may be used.

In addition, the piston 60 is installed on the upper side of the divided space, so that when the mixed expansion of the two reactants, the piston 60 slides upward by the expansion force, applying pressure to the extinguishing agent filled thereon. It is configured to.

In addition, the bottom surface of the main body 10, the second safety piece 70 for suppressing the rotation of the rotary knob 55 is coupled, so as to block the dividing space of the rotary knob 55 It would be desirable to configure to keep the state stable.

As shown in the second safety piece 70, both ends of the inner side surfaces of the main body may be formed in the state in which the exposed portion of the rotary knob 55 is inserted into the receiving groove 75 formed on the inner side of the center. 10) It may be composed of an elastic body of the 'c' shape that is tightly coupled to the bottom of each side.

The second safety piece 70 also protrudes the fitting protrusions 78 on the inner side surfaces of both ends thereof, and respectively fits the bottoms of the side walls of the main body 10 corresponding to the fitting protrusions 78, respectively. By forming the grooves 18, it is preferable that the coupling state of the second safety piece 70 is stably maintained by the coupling between the fitting protrusions 78 and the fitting grooves 18, of course. to be.

Referring to the use of the same throwing fire extinguisher configuration as described above are as follows.

First, in a state where the first safety piece 30 and the second safety piece 70 are coupled to the throwing fire extinguisher according to the present invention, the rotation of the rotary knob 55 is suppressed by the second safety piece 70. The two reactants under the main body 10 are kept insulated from each other, thereby preventing the raising of the piston 60 and the increase in pressure of the extinguishing agent, and the main body by the first safety piece 30. By keeping the barrel 10 and the lid 20 in close contact with each other, it is possible to prevent the rupture of the rupture pin 12 and the opening of the lid 20, and accordingly, the throwing fire extinguisher according to the present invention. It can be safely stored and moved.

When the fire extinguisher is to be suppressed using the throwing fire extinguisher, the first safety piece 30 and the second safety piece 70 are separated from the throwing fire extinguisher and the rotary knob 55 is rotated. When the fire extinguisher is thrown to the point where there is a fire, by the extinguishing agent pressure inside the main body 10, the bursting pin 12 is ruptured and the lid 20 is opened, thereby extinguishing agent in the main body 10 is sprayed to the outside. It will fight the surrounding fire.

At this time, when the first safety piece 30 is separated, the bursting pin 12 is configured to have a strength that withstands the extinguishing agent pressure in the main body 10 for a few seconds to several tens of seconds, the bursting fire extinguisher, While flying to the point where the fire is extinguishing agent is suppressed after falling to the point of fire, the rupture pin 12 is ruptured and the lid 20 is opened while the extinguishing agent is ejected. In addition, when the extinguishing agent is ejected, the two reactants under the main body 10 are mixed and expanded to raise the piston 60, so that the pressure of the extinguishing agent is increased to eject the extinguishing agent more strongly. As the main body 10 rotates in all directions, the extinguishing agent is ejected to effectively extinguish the fire at the point where the extinguishing agent is dropped.

And, even when the pressure of the extinguishing agent filled in the main body 10 is not enough to rupture the rupture pin 12, or if the strength of the rupture pin 12 is made more than a predetermined reference value, The extinguishing agent is pressurized due to the rise of the piston 60 due to the expansion and mixing of the two reactants, thereby increasing the internal pressure thereof, thereby making it possible to easily rupture the rupture pin 12, thereby providing reliable reliability of the thrown extinguisher. It will be able to secure the injection function.

Since the fire extinguisher described above is for throwing, of course, the user should be made to have a size and weight that can be thrown by one hand.

As can be seen by the above embodiments, according to the throwing fire extinguisher according to the present invention, when the user throws the fire extinguisher itself to the fire point, the extinguishing agent is automatically ejected from the fire extinguisher dropped at the fire point to suppress the fire, so as to extinguish the fire A person who wants to fire can extinguish a fire without getting close to the fire point, thereby preventing a fire extinguisher from being burned by a sudden fire during fire extinguishing, and a person who is afraid of a fire It is effective to extinguish fire easily by using fire extinguisher.

In addition, the throwing fire extinguisher according to the present invention, not only has a size and weight that can be thrown with one hand, but also because the method of use thereof is simple, there is an effect that can be easily used by children or elderly people with weak strength.
