Description

FIELD OF THE INVENTION [0001] The present invention relates to a fire extinguisher for fire extinguishers,

The present invention relates to a fire extinguisher for fire extinguishers and fire extinguishers therefor. More particularly, the present invention relates to fire extinguishers for fire extinguishers which are exposed in a short time, and fire extinguishers therefor.

Initiators, such as gunpowder, that are instantly bulky due to external impact or heat, are typically exploded by an explosive device. These detonators are mainly used for explosive materials, but they are also widely used in solid aerosol fire extinguishing systems that spray fire extinguishing agents.

Here, the above-mentioned solid aerosol fire extinguishing apparatus is roughly classified into a small portable fire extinguisher called a hand held and a medium-sized fire extinguisher based on size. In the solid aerosol fire extinguishing device, a powdered fire extinguishing agent is embedded in the inside of the solid aerosol fire extinguishing device together with the above-mentioned detonating device, and when the detonator is operated by operating buttons or operating levers, fire extinguishing agent is generated while extinguishing agent is burned. And, in the solid aerosol fire extinguishing system, the extinguishing component is injected through the nozzle by the pressure of the gas generated together with the extinguishing component.

These solid aerosol fire extinguishing systems are superior to other fire extinguishing systems because of the small size of the particles generated during combustion. Therefore, the solid aerosol fire extinguishing system is used in various places such as factories, art museums, libraries, computer rooms, mobile communication facilities, ships and the like, and recently it is installed in vehicles.

On the other hand, the aforementioned solid aerosol fire extinguishing device is provided with an explosion device as disclosed in Korean Patent No. 10-1118618 (an activating part for a solid aerosol fire extinguishing device). 1, the detonator has a housing 5 in which a space into which the extinguishing agent 3 is inserted is provided and a through hole 5a is formed at one end and a through hole (not shown) of the housing 5 5a to heat the extinguishing agent.

The heating unit 7 includes a cylindrical insulator 7a that is seated in the through hole 5a and a terminal 7b that is integrally connected to the insulator 7a and is connected to the terminal 7b And a heating coil 7c heated by a power supply.

When the heating unit 7 is supplied with power from the outside to the terminal 7b, the heating coil 7c of the terminal 7b is heated to heat the extinguishing agent 3 inside the housing 5, And the like.

However, since the heating part of such prior art is assembled in such a manner that the insulating material of a cylindrical structure is fitted into the through hole of the housing, the heating amount of the heating coil is basically difficult to increase. In other words, It is necessary to change the size of the through hole of the housing. In such a case, the size of the detonator must be increased.

In addition, since the heating coil is disposed on one end face of the insulating material, the contact area between the heating coil and the extinguishing agent inside the housing is minimized, and the heat generating function is lowered accordingly.

On the other hand, in the detonator described above, the heating portion 7 is heated by the power source of a battery (including a rechargeable type) not shown. However, such an explosive device has a low power density stored in the battery, and the output is limited because the battery is connected to the heating portion 7 by the equivalent series resistance method. That is, the detonator described above can not provide high-density power. Therefore, the above-described detonator can not heat the heating unit 7 in a short time because the supply amount of the power source is limited, so that the extinguishing agent 3 can not be ignited quickly.

In addition, since the battery is connected to the heating unit 7 by the equivalent series resistance method, leakage current is generated in the battery during long-term storage and the battery power is weakened.

Particularly, since the plate-like base plate constituting the heating element is made of ceramic, heat can be generated with high heat and the heat-generating portion is formed as a pattern on the base plate so as to be easy to manufacture and there is no fear of disconnection, The plate can be easily heated as a whole.

In addition, since the power terminal is brazed to the brazing portion of the base plate, the power terminal is easily fixed to the base plate.

In addition, when the plurality of heating elements are formed in the overlapping state, not only the heating efficiency can be doubled, but also the heat generation amount can be controlled by controlling the quantity of the heating elements.

Hereinafter, an explosion device for a fire extinguisher and an extinguisher thereof according to an embodiment of the present invention will be described with reference to the accompanying drawings.

2, the fire extinguisher for a fire extinguisher according to the embodiment of the present invention is provided with a heating element 10 composed of a base plate 11, a heat generating portion 12, and a power source terminal 13.

The base plate 11 is formed in a plate shape as shown in Fig. 2, and is made of a heat transfer material capable of generating heat. The base plate 11 can be made of, for example, a thin plate ceramic having high thermal conductivity. Particularly, it is preferable that the base plate 11 is made of a ceramic material of 90% or more of alumina so that the heat transfer performance is excellent and the weight can be reduced.

The heat generating portion 12 is provided on the surface of the base plate 11 as an identical body and generates heat as shown in FIG. It is preferable that the heat generating portion 12 be formed of, for example, a heat transfer pattern printed on at least one of the both side surfaces of the base plate 11 and made of a conductive material. That is, the heat generating portion 12 is constituted by a heat transfer pattern such as a normal heat line printed in a pattern on a window of a vehicle. In particular, it is preferable that the heat generating portion 12 is formed in a zigzag shape as shown in the figure so as to maximize the heating efficiency. The heat generating portion 12 is preferably made of tungsten or a mixture of tungsten and molybdenum so as to have excellent heat transfer performance and heat resistance to high temperature, and a conventional corrosion inhibitor can be applied to the surface.

The heat generating portion 12 is formed on the surface of the base plate 11 and exposed to the outside as shown in FIG. As shown in the drawing, the heat generating part 12 is preferably positioned at an inner side of the brazing part 11a when a groove-shaped brazing part 11a, which will be described later, is formed on the base plate 11.

The power supply terminal 13 supplies power to the heat generating unit 12 to generate heat. The power supply terminal 13 may be formed of, for example, a wire as shown in FIG. 2, or alternatively may be formed of a common lead wire not shown. Alternatively, the power supply terminal 13 may be formed of a metal foil having a wire or a lead wire connected by soldering You may. The metal foil is preferably made of a metal foil usually used for applying power to the end of the heat ray for a window. The power supply terminals 13 are composed of a plurality of power supply terminals 13 and are respectively connected to one end and the other end of the heating unit 12 by soldering or brazing described later. The power supply terminal 13 is supplied with power from the ignition power supply means described later.

2, the base plate 11 is formed in a shape of a groove on the surface of the base plate 11, as shown in the upper side of FIG. 2, so that the end of the power terminal 13 is easily brazed when the power terminal 13 is constituted by an electric wire, The brazing portion 11a of the brazing portion 11a is provided. In the brazing portion 11a, the end portion of the heat generating portion 12 is positioned as described above. It is preferable that the brazing part 11a is constituted of a plurality of parts as shown in the figure so that both ends of the heating part 12 are positioned separately. The brazing portion 11a is made of a conductive material such as silver or copper and is brazed in a state in which the end of the power source terminal 13 is seated. Accordingly, the power terminal 13 is hardened after the melting of the usable agent by the brazing, so that the end portion is firmly fixed to the brazing portion 11a. At this time, the power supply terminal 13 is electrically connected to the heat generating portion 12 by the use agent.

As shown in FIG. 2, the brazing portion 11a may be formed in the shape of a letter "A" so that the end of the power source terminal 13 is seated on the end portion thereof. It is preferable that the brazing portions 11a are formed alternately in the base plate 11 as shown in the figure so that the occupied area in the base plate 11 is minimized.

Here, the size (length, width, and thickness) of the base plate 11 is determined according to the intensity of the power supplied through the power terminal 13. For example, when power of 27 V is applied through the power supply terminal 13, the base plate 11 has a length of 12.0 mm ± 0.5 mm, a width of 3.0 mm ± 0.2 mm, Thickness 0.42 mm 占 0.03 mm. Alternatively, the base plate 11 may have a length of 7.0 mm ± 0.5 mm, a width of 5.0 mm ± 0.3 mm, and a thickness of 5.0 mm ± 0.3 mm so as to generate heat in a high temperature by an applied power when a power source of 3 V to 9 V is applied through the power terminal 13. 0.42 mm ± 0.03 mm. If the base plate 11 is larger than or smaller than the above-mentioned size, the heat generation may be insufficient or overheated. Therefore, since the base plate 11 is manufactured as described above, it can be applied to a building-use fire extinguisher using a power source of 27V or a portable handheld using a power source of 3V to 9V.

In order to improve the electrical stability and responsiveness of the heat generating element 10 constructed as described above, it is possible to concentrate the heat while minimizing the exposed surface area of the heat generating portion 12, So that a two-layer structure can be produced. When the heating element 10 has a two-layer structure, the power terminal 13 may be connected in series for the application of a high voltage such as 27 V. In order to apply a low voltage such as 3 V to 9 V, They may be connected in parallel. Since the heating elements 10 are constructed in a multi-layer structure, the heating area can be doubled while minimizing the installation area. Therefore, it is possible not only to generate heat in a short period of time, but also to ignite the initiator such as a flammable substance (F) to be described later by heating it to a high temperature in a short time.

On the other hand, the deton device for a fire extinguisher according to the embodiment of the present invention includes the above-described heating element 10 and the cable 60 as shown in Fig. 4, and a casing described later.

The heating element 10 is connected to the cable terminal 63 of the cable 60 so that the power terminal 13 is supplied with power from the cable 60 as shown in Fig.

The casing is embedded with a pyramid material (not shown) as shown in Fig. The casing may be composed of, for example, a hollow tube 20 and a cap 40 as shown in Fig. 6, a part of the heating element 10 and the cable 60 are respectively located on one side and the other side of the inside of the hollow tube 20, the other side where the cable 60 is located is sealed by cogging, 10 is embedded in a printed material F (not shown). The cap 40 seals one side of the hollow tube 20 where the heating element 10 is located, as shown in Fig. At this time, as shown in the drawing, the central portion of the cap 40 is convexly formed inside the hollow tube 20, thereby compressing the powdery fluorescent material F filled in the hollow tube 20. The casing is sealed by the cap 40 and the cable 60 so as to isolate the heating element 10 and the print material F from the outside.

As shown in FIGS. 4 and 6, the hollow tube 20 is provided with an orifice 21 on one side where the heating element 10 and the phosphorous material F are embedded. The orifice 21 ejects the combustion gas generated by the combustion of the flammable substance F, that is, the flammable substance F, to the outside when the flammable substance F is ignited by the heating of the heating element 10 . At this time, since the hollow tube 20 ejects the flammable substance F to be vaporized only to the orifice 21, the vaporized flammable substance F can be ejected at a high pressure.

The hollow tube 20 may be provided with a thread 25 on the outer circumferential surface thereof, as shown in FIG. The hollow tube 20 may be provided with a fastening polygonal surface 26 as shown in FIG. Accordingly, the hollow tube 20 can be screwed into the fire extinguisher 100 as shown in FIG.

The cable 60 is connected to a connector 90 to which external power is supplied as shown in FIG. The cable 60 is connected to the ignition power supply means described later through the connector 90 and is supplied with power from the ignition power supply means. The cable 60 is composed of a mold 65, a cable terminal 63 and a cable cable 62 as shown. The mold 65 has grooves along the circumferential direction as shown and has first and second step portions 65a and 65b. The cable terminal 63 protrudes from the end of the mold 65 as shown and is connected to the power terminal 13 of the heating element 10 described above. The cable cable 62 is connected to the connector 90 as shown to apply the power of the connector 90 to the cable terminal 63. At this time, the cable cable 62 applies power through the inner wire 61 as shown in FIG. The cable 60 transmits the power of the connector 90 to the power supply terminal 13 of the heating element 10 through the cable cable 62 and the cable terminal 63. [

The cable 60 is embedded in the hollow tube 20 of the casing in the mold 65 as shown in Fig. The cable 60 is fixed to the other end of the hollow tube 20 as the mold 65 is formed as the hooking jaw 22 is formed while the other end of the hollow tube 20 is cogged as shown in the drawing. At this time, the mold 65 is slightly stretched by the grooves between the first and second step portions 65a and 65b as shown, so that the mold 65 is smoothly cogged and the assembly tolerance is adjusted. The mold 65 seals the other end of the hollow tube 20 by cogging to prevent the heating body 10 from being detached from the hollow tube 20.

5 and 6, the cable 60 is attached to the stepped mounting portion 23 formed at the other end of the hollow tube 20 at a depth set to the inside of the hollow tube 20 as the mold 65 is caught, . That is, the entry of the cable 60 to the inner side of the hollow tube 20 is restricted by the step seating portion 23.

Meanwhile, the hollow tube 20 of the casing further includes a fastener that supports the heating element 10 inside and fixes the heating element 10 in place. The fastener can be constituted by, for example, a hollow sleeve 30 supporting the side of the heat generating element 10 as shown in Figs. As shown in the figure, the sleeve 30 is formed of a flexible material such as a rod or a block formed in a long shape along the longitudinal direction of the hollow tube 20, as a guide hole 31 through which the heating element 10 passes, Can be configured. That is, the sleeve 30 is formed of a rod or a block type packing in which a guide hole 31 is formed. Particularly, the sleeve 30 is preferably made of a material such as rubber or urethane so that the heating element 10 can be easily inserted into the guide hole 31 and the heating element 10 can be water tight. As the sleeve 30 is formed to be long, the sleeve 30 is easily inserted into the hollow tube 20 and easily supports the heating element 10 fitted in the guide hole 31. The sleeve 30 is made of a packing so that the heat emitting body 10 fitted to the guide hole 31 is protected from impact while being insulated from the outside as well as water tight. In addition, when the sleeve 30 is made of an elastic material, the sleeve 30 is expanded and contracted during assembly to reduce the assembled scattering.

The sleeve 30 is inserted into the hollow tube 20 in a state where the heating body 10 is fitted in the guide hole 31 as shown in FIG. At this time, the sleeve 30 prevents the heating element 10 from rubbing against the inner circumferential surface of the hollow tube 20 to protect the heating element 10.

5 and 6, an end portion of the sleeve 30 is engaged with an inner step 24 formed at one end of the hollow tube 20. As shown in FIG. Therefore, the sleeve 30 can no longer enter the hollow tube 20 and is fixed at a predetermined position.

The sleeve 30 is splined to the engagement protrusion 64 formed in the mold 65 of the cable 60 as shown in Figs. Thus, the sleeve 30 is not only prevented from rotating, but is also easily fixed in place.

4 and 6, when the stopper 80 is provided, the sleeve 30 is protected by the stopper 80 at one side opposed to the print material F. As shown in FIG. The stopper 80 is formed in a shape corresponding to the cross-sectional shape of the sleeve 30 as shown, and is preferably made of a metal material. The stopper 80 protects the one side of the sleeve 30 by intercepting the heat generated when the flammable substance F is ignited.

Meanwhile, the hollow tube 20 of the casing may be provided with a filter 50 as shown in FIGS. The filter 50 is composed of a cylindrical net having holes smaller than the particles of the powdery flammable substance F to be filled in the hollow tube 20. The filter 50 prevents the powdery fluorescent material F filled in the hollow tube 20 from flowing out to the orifice 21 of the hollow tube 20. However, the filter 50 permits the evacuation of the gaseousized burned substance F of the burning substance F. [ Thus, the hollow tube 20 can jet only the gasified phosphor material F to the orifice 21. [

4 and 6, the hollow tube 20 may be provided with a flexible washer 70. [ The washer 70 is seated on the mold 65 of the cable 60 as shown in Fig. 6 and is pressed against the step seating portion 23 formed at the other end of the hollow tube 20 during cogging of the hollow tube 20 do. At this time, the washer 70 is configured to damp the pressure at the time of cogging while expanding and contracting to protect the components such as the sleeve 30 and the mold 65 built in the hollow tube 20 from excessive pressure, . Of course, the washer 70 can adjust the assembly tolerance according to the thickness to be stretched.

On the other hand, the flammable substance (F) described above can be applied to various flammable substances such as explosives and charcoal powder. However, it is preferable to use the same solid aerosol fire extinguishing powder as the fire extinguishing agent filled in fire extinguishers. It may be constituted of a powder type applied directly or a solid material obtained by solidifying the powder type. Such solid aerosol digestion powders are activated during heating as described in the prior art to generate high temperature and high pressure gas to operate the fire extinguisher.

7, the explosive device of the present invention is constituted as described above with reference to FIG. 7, in which a hollow tube 20 (see FIG. 7) of a casing in which a heating element 10 is housed is housed in a fire extinguisher case C of a fire extinguisher 100 filled with an extinguishing agent 101 And the power of the connector 90 is supplied through the cable 60 when the ignition switch S provided in the state of being exposed to the fire extinguisher case C is operated (the connector is supplied from the ignition power supply means The heating element 10 generates heat. 2, since the power source of the cable 60 is applied through the power source terminal 13, the heating unit 12 of the heating pattern generates heat and the ceramic base plate 11 is heated Heat it. Therefore, the heating body 10 heats the charged flammable material F inside the filter 50 as shown in Fig. 6 and converts it into gas.

The filter 50 discharges the vaporized flammable substance F to the outside. Thus, the hollow tube 20 of the casing injects the vaporized photoresist F through the orifice 21. [ At this time, the hollow tube 20 injects the pyrophoric material F gasified at a high pressure because the pyrophoric material F is vaporized and expanded in volume. Accordingly, the extinguisher 100 ejects the extinguishing agent 101 since the extinguishing agent 101 filled in the inside of the extinguisher 100 is heated to a high temperature and high pressure and is converted into the extinguishing gas. That is, the extinguisher 100 injects the extinguishing agent 101 through the injection port of the case C (not shown) as the extinguishing agent 101 is burned by the gasified burning substance F.

On the other hand, the heating body 10 is firmly fixed to the inside of the hollow tube 20 by the sleeve 30. Then, the sleeve 30 is protected from the heat of explosion as the stopper 80 of the ignition of the flammable substance F shields one end portion.

The detonating device for a fire extinguisher according to the present invention includes ignition power supply means electrically connected to the heating element 10 through the connector 90 and the cable 60 to supply ignition power to the heating element 10 . The ignition power supply means supplies the power stored in the power supply terminal 13 of the heating element 10 as an ignition power source and constitutes a part of the detonator so as to be embedded in the extinguisher 100 together with the components of the detonator described above .

The ignition power supply means may comprise, for example, a battery B, an energy storage device E and an ignition switch S, as shown in Figs. The positive electrode (+) of the battery B is connected to one end of the energy storage device E and one end of the ignition switch S, respectively. The cathode (-) of the battery B is connected to the other end of the energy storage device (E) and one end of the power supply terminal of the heating element 10, respectively. The ignition power supply means is constituted such that the other end of the ignition switch S is connected to the other end of the power supply terminal of the heat generating element 10 so that the power of the battery B is supplied to the energy storage device E, Electric energy is supplied to the power supply terminal 13 of the heating element 10 through the ignition switch S. That is, the ignition switch S interrupts the stored power supplied to the heating element 10 to ignite the printing material F through the heating element 10. At this time, the ignition switch S is mounted on the outside of the fire extinguisher 100 as described above.

The energy storage device (E) stores electric energy sufficient for electric energy to be completely stored or ignited through the heating element (10).

The current flows between the battery B and the energy storage device E when the ignition switch S is off and the voltage difference between the voltage of the battery B and the voltage of the energy storage device E is present. 8 (a), when the voltage of the battery B is higher than the voltage of the energy storage device E, the current flows from the battery B to the energy storage device E, (E).

As shown in Fig. 8 (b), the aforementioned battery B, energy storage device E and ignition switch S are connected in a circuit. Therefore, when the ignition switch S is turned on, the current from the battery B or the energy storage device E flows into the heating element 10 through the ignition switch S in the ON state, 10), the ignition is performed. At this time, the energy storage device E applies a current to the heating element 10 through the above-described cable 60 when the ignition switch S is operated.

It is preferable that a super capacitor or a super capacitor is applied to the energy storage device (E). Since a supercapacitor or a super capacitor has a minute leakage current value, it can maintain a long-term power storage state, has a very low internal resistance, It is possible to supply a high current to the heating element 10 instantaneously after the ignition switch S is turned on so that the time from when the ignition switch S is turned on to when ignition occurs can be reduced as compared with the prior art, Lt; / RTI >

Here, the above-described energy storage device E may be constituted by one unit, but may alternatively be constituted by a plurality of units. In this energy storage device E, the quantity is determined according to the required power storage capacity.

On the other hand, the ignition power supply means according to the embodiment of the present invention is constituted in the circuit of the above-mentioned ignition power supply means, and is connected to the heating element 10 in accordance with the capacitance of the power source stored in the energy storage device E And energization control means for controlling energization of the stored power source to be applied.

The energization control means is disposed between the heating element 10 and the energy storage device E as shown in Fig. 9, for example. The energization control means is connected to the anode of the battery (+) and one end of the energy storage device And a MOSFET (P) whose drain terminal is connected to the heating element (10) and whose source terminal is connected to the negative terminal of the battery (-) and the other end of the energy storage device (E).

When the ignition switch S is in an off state, a current can flow between the battery B and the energy storage device E. At this time, when a voltage higher than the gate-to-source threshold voltage of the MOSFET (P) is applied to both ends, a channel between the drain and the source is formed and the MOSFET (P) can be conducted. However, since the ignition switch S is in the OFF state, no current is supplied to the heating element 10. [

The MOSFET P maintains the conduction state when a sufficient voltage is applied from the battery B or the energy storage device E to the MOSFET P so that when the ignition switch S is turned on, The electric current from the energy storage device E accumulated by the ignition switch B can be applied to the heating element 10 through the ignition switch S and thus ignition occurs.

The battery B or the energy storage device E gradually discharges and the battery B or the energy storage device E is discharged as electric energy is supplied from the battery B or the energy storage device E to the heating element 10. [ Source channel of the MOSFET P is lower than the gate-source threshold voltage of the MOSFET P, electric energy is not supplied to the heating element 10 and ignition is not performed even if the ignition switch S is turned on .

Accordingly, since excessive electric energy is supplied to the heating element 10, it is possible to prevent further explosion after ignition, and to prevent a safety accident by shutting off an overcurrent in a short circuit of a circuit constituting the ignition power supply means.

As a result, when the power stored in the energy storage device E is stored at a predetermined voltage, the MOSFET P generates a heat by heating the heating element 10 by applying the stored power to the heating element 10, When the voltage is lower than the set voltage, the power source is blocked from being applied to the heating element 10 to prevent overheating of the heating element 10, and also to prevent a safety accident by shutting off an overcurrent in a short circuit.

On the other hand, when the battery B or the energy storage device E, particularly the super capacitor, is charged, a natural discharge occurs due to an internal resistance or a physical action. Therefore, even if the electric energy is not supplied to the heating element 10, .

In the embodiment described above, the means for supplying the electric energy to the heat generating element 10 is the battery B and the energy storage device E is the battery B for compensating the physical discharge in the energy storage device E. A natural discharge occurs in the battery B and the battery B is no longer discharged from the energy storage device E due to the discharge due to the continuous supply of electric energy to the energy storage device E connected in a circuit, Can not be compensated.

In order to compensate for this, in the detonator for a fire extinguisher according to an embodiment of the present invention, as shown in Fig. 10, the ignition power supply device includes not only the MOSFET P described above but also the insulation switch S ').

In order to use the fire extinguisher, the user must remove the safety pin of the fire extinguisher before the ignition switch S is pressed. In the embodiment of the present invention, the safety pin is interlocked with the insulation switch S ' The isolation switch S 'is turned on. It is preferable that the isolation switch S 'is constituted by a circuit so as to be electronically operated.

When the isolation switch S 'is off, the electrical connection between the battery B and the energy storage device E is cut off so that no current flow occurs in the ignition power supply means.

However, when the safety pin is removed and the insulation switch S 'is turned on, the battery B stores the energy storage device E, and the energy storage device E is charged to a sufficient level The electric energy stored in the energy storage device E is supplied to the heating element 10 and ignition occurs when the ignition switch S is turned on.

It is preferable that sufficient energy storage is performed in the energy storage device E for a period of time after the safety pin is removed and the ignition switch S is turned on. In the energy storage device E, for example, in the case of a supercapacitor, The speed at which electricity is stored in the supercapacitor can be adjusted in accordance with the combined resistance in the circuit of the supply means, the capacitance of the supercapacitor and the current capacity of the battery (B).

That is, the ignition power supply device according to the embodiment of the present invention prevents ignition if the voltage of the energy storage device E is below a certain voltage (below the gate-source threshold voltage of the MOSFET) The electrical connection of the detonator can be protected and electric energy can be supplied from the battery B to the energy storage device E only when ignition is required, so that the life of the battery B can be further increased as compared with the conventional case.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, It should be understood that all of the techniques that can be easily changed and used by those skilled in the art are included in the technical scope of the present invention.
