Description

  The present invention is suitable for a simple fire extinguisher for home use or office use, for example, and simply breaks a loaded small gas cylinder, temporarily blocks the outflow of the fire extinguisher gas by a valve, and eliminates the expense of the fire extinguishing gas. In addition to ensuring effective use and effective fire extinguishing, fire extinguishing gas is reliably and accurately injected toward the fire source during fire extinguishing, realizing effective and effective fire extinguishing and reliable initial fire extinguishing, and fire occurrence The present invention relates to a fire extinguisher gas injector, which sometimes announces the location of a fire extinguisher, and promotes prompt use of the fire extinguisher and initial fire extinguishing.

For example, a general fire extinguisher installed in a home or office has a problem that it is large and heavy, requires an arm for a fire extinguishing operation, and is generally difficult to use.
For this reason, various small and lightweight simple fire extinguishers have been proposed in order to solve the above problems in the past, and the structure is roughly divided into a cylinder or a cover by a sealing method of a gas cylinder sealing plate. It was divided into one that turns, one that pushes down the operation block, and one that strikes the top or bottom of the cylinder.

  Among these, as a cylinder or cover to be rotated, a tube body that accommodates the gas cylinder, an upper cover body screwed to the upper end portion of the tube body, and a cylinder fitting body that can be screwed into a mouth screw of the gas cylinder, And a nozzle body equipped with a firing needle, the central cylinder portion of the cylinder fitting body is inserted into the opening at the upper end of the tube body, the nozzle body is inserted inside the central cylinder portion, and the upper portion of the nozzle body is Insert into the opening of the upper cover body, and when the fire is extinguished, rotate the upper cover body or tube about the axis, move the firing pin to the gas cylinder side to break the sealing plate, and supply the cooling gas from the nozzle nozzle There is what is ejected (see, for example, Patent Document 1).

  In addition, an operation surface and a safety block hook are provided on the upper part of the case that can hold the gas cylinder to push down the operation block, and the shaft body with the firing needle can be slid up and down inside the case. The retaining groove of the shaft body is hooked with a retainer, and when the fire is extinguished, the safety block is pulled down via the hook, and the operation surface is pressed to move the retainer to the back. The engagement with the edge of the shaft is released, the shaft body is pushed down by the elasticity of the spring, the firing needle is moved to the gas cylinder side to break the sealing plate, and the jet gas is guided to the inside of the shaft body. (For example, refer to Patent Document 2).

  In addition, the gas cylinder is accommodated inside the pipe body with the cover attached, and a dish-shaped nozzle is attached to the lower end of the pipe body, and a pusher guide is attached to the upper end of the pipe body. Attach the body and slidably install the pusher with the firing needle attached to the guide body, and always insert the safety plate into the pusher to prevent its movement, while inside the pusher guide body Attach the cylinder receiver, screw the gas cylinder mouth screw into the receiver, pull out the safety plate attached to the pusher during fire extinguishing, hit the outside of the pusher with your hand, and push it inward. There is one that moves the firing needle to the gas cylinder side, breaks the sealing plate, guides the ejected gas from the inside of the pipe body to the inside of the shaft body, and injects this from the injection hole (for example, Patent Document 3). Irradiation).

However, among the simple fire extinguishers, the one that rotates the cylinder or the cover has a small displacement of the firing needle with respect to the rotation amount, and in order to sufficiently break the sealing plate, the rotation amount of the cylinder or the cover is increased. In that case, there was a problem that it took a lot of time and effort to quickly extinguish the fire.
In addition, when the operation block is pushed down, a safety block lowering operation and an operation surface pressing operation are required, and there is a problem that the operation during fire extinguishing becomes complicated.
In addition, when the head or bottom of the cylinder is hit, the operation at the time of fire extinguishing is relatively easy and can be extinguished quickly. However, since the safety plate is exposed to the outside, the plate is mischievous. If it was pulled out by mistake, the sealing plate could be broken.

  Moreover, although all of the above-mentioned fire extinguishers are ruptured with the nozzle hole facing the fire source, the operation concentrates on the rupture at the time of digestion, so it is difficult to accurately direct the nozzle hole to the fire source. The initial gas is wasted or cannot be used effectively for fire extinguishing, and the opportunity for initial fire extinguishing will be missed while the remaining gas will be used for substantial fire extinguishing. There was a problem that gas could not be used effectively.

By the way, when a fire extinguisher is actually used in the event of a fire, there is a possibility that the initial fire extinguishing time may be lost due to a panic, distraction, or the location of the fire extinguisher being unknown or forgotten.
In particular, such a problem is conspicuous during fire extinguishing at night or during a power failure.
As a solution to such a problem, there is a fire extinguisher provided with a power supply unit, a switch, and an alarm transmission unit so as to issue an alarm when the switch is turned on (see, for example, Patent Document 4).

  However, since the fire extinguisher is provided with a switch in the safety plug, the safety plug is pulled out and the switch is turned on, and the location of the fire extinguisher is premised, the location of the fire extinguisher is unknown and the location of the fire extinguisher is unknown. In such a case, the fire extinguisher cannot be used, and it takes time to send an alarm, so there is a problem that it takes time and cannot be used quickly.

Next, the connection terminal 51 is attached to the inner surface of the upper case 1, the connection terminal 52 is attached to the outer surface of the lower case 10, and they are brought into contact with each other with an insulating film interposed therebetween.

Before and after this, the cut case divided into two is disposed opposite to the outer housing 19 and joined with a screw or an adhesive to form a substantially cylindrical shape between the opening 2 at its upper end. The operation lever 27 is disposed in the lower case 10 and the lower case 10 is inserted into the lower end.
Then, a safety ring 55 is fitted into the peripheral surface of the lower case 10 exposed at the lower end of the upper case 1, and the upper and lower ends of the ring 55 are connected to the lower end portion of the upper case 1 and the lower case. -If it arrange | positions so that engagement to the flange part of S10 is possible, a series of manufacture will be complete | finished.

The fire extinguishing gas injector F ₁ assembled in this way is formed in a generally cylindrical shape, with the lower case 10 being lightly pressed and held at the lower end of the upper case 1 before the gas cylinder 11 is loaded. .
The ejection hole 3 and the illumination hole 4 are located close to each other in the upper part of the front surface of the upper case 1, the ejection hole 25 is located at the back of the ejection hole 3, and the lamp 48 is located in the illumination hole 4. A notification device 53 is exposed immediately below the lamp 48.

Under such circumstances, the cylinder holder 15 is urged downward by the spring 42 inside the outer housing 19, separated from the tear holder 21, and the locking pin 24 engages with the lower end of the long hole 23. It is stationary at the position.
Further, the control valve 38 is attached to the valve mounting hole 33 by airtightly engaging the valve body. The control valve 38 biases the valve rod 40 upward by a built-in spring (not shown), and the inner valve 41 that moves is controlled by the valve body. The inner valve 41 is kept closed by being pressed against the lower end of the inner valve 41.

  Further, the push rod 35 directly above the control valve 38 is biased upward by the elasticity of the spring 37, and its upper end protrudes to the outside of the outer housing 19 and engages with the protrusion 29 on the lower surface of the operation lever 27. The operation lever 27 is pushed up.

On the other hand, the front end portion of the locking pin 24 engages with the locking piece 7 at the lowest position, and the upper case 1 is separated from the lower case 10.
Accordingly, the non-conducting state of the contact terminals 51 and 52 is maintained, and power is not supplied from the battery 50 to the lamp 48, so that the lamp 48 is turned off.
It should be noted that the fire alarm 54 does not operate during normal times when no fire occurs, so the notification device 53 stops operating and does not generate a notification sound.

Next, when installing the fire-extinguishing gas injector F ₁ in preparation for use, the lower case 10 is first pulled out from the upper case 1, and the unused gas cylinder 11 is removed from below the upper case 1. The screw portion 14 around the mouth is inserted into the screw hole 16 of the cylinder holder 15 and loaded.
Thereafter, the lower case 10 is inserted into the lower end portion of the upper case 1, the bottom portion of the gas cylinder 11 is fitted therein, and this is installed in a standing position at a predetermined position.
In this case, it is desirable to prevent overturning using an appropriate attachment. This situation is as shown in FIGS.

The fire-extinguishing gas injector F ₁ loaded with the gas cylinder 11 is substantially the same as the above-described situation after the assembly, and the tip 45a of the needle tube 45 is located above the sealing plate 13 while being separated from the sealing holder 13 21 and the cylinder holder 15 are separated from each other, and the guide hole 32 and the injection hole 25 of the outer housing 19 communicate with the injection hole 3.

When a fire occurs under such installation conditions, the fire alarm 54 automatically detects this, or the fire alarm 54 is activated and issues an alarm through human operation.
When the alarm is input to the notification device 53, an internal receiver or microphone (not shown) detects this, amplifies the input signal, removes noise other than the alarm, and fires the input signal. When recognizing the alarm of the alarm device 54, a notification signal having a tone different from that of the alarm is emitted from the transmitter.
Therefore, the location of the fire extinguishing gas injector F ₁ can be known from the notification signal, prompting its rapid use, and promptly responding to the initial fire extinguishing.

Thus, when the location of the fire extinguishing gas injector is known, the fire extinguishing gas injector F ₁ is held, the gripping portion 55 a of the safety ring 55 is pulled to the side, and this is removed from the peripheral surface of the lower case 12. Thus, the lower case 12 can be pushed.
Under such circumstances, the fire extinguishing gas injector F ₁ is held and the lower case 12 is pushed up, or the injector F ₁ is installed on the floor, and the head of the upper case 1 is attached to the spring 42. Press down against the elasticity of the.

  As a result, the upper case 1 moves to the lower case 12 side against the elasticity of the spring 42, or the lower case 12 is pushed into the upper case 1 side, and the case is moved. -When the contact terminal 51 moves relatively integrally with the contact 1 and the terminal 51 exceeds the intervening position of the insulating film (not shown), it contacts the other contact terminal 52, and these are electrically connected. .

For this reason, the lamp 48 is energized from the battery 50, and the lamp 48 is turned on.
Therefore, the fire source can be easily confirmed at night and the like, and fire extinguishing work can be performed reliably, and after extinguishing the fire, it can be used as a guide light for evacuation.
Thereafter, the lamp 48 continues to be lit until the voltage of the battery 50 is consumed below a predetermined value. This situation is as shown in FIG.

  On the other hand, when the lower case 12 is pushed up or the head of the upper case 1 is pushed down as described above, the gas cylinder 11 moves up relatively, and the cylinder holder 15 moves together with this to move the spring 42. The locking pin 24 that is pressed and shrunk and protrudes from the cylinder holder 15 moves up along the long hole 23.

Thus, the mouth portion of the gas cylinder 11 moves close to the tip end portion 45a of the breaking member 45, and the tip end portion 45a is pierced into the sealing plate 13 to be sealed.
In this case, since the pointed portion 45a pierces the central portion of the thin plate of the sealing plate 13 and breaks it, it can be reasonably and easily broken.

Then, when the cylinder holder 15 is moved up in the outer housing 19 by the length of the long hole 23 and the locking pin 24 is engaged with the upper end portion of the long hole 23, the cylinder holder 15 stops moving upward, and at the same time, the needle tube The piercing operation of 45 is stopped. This situation is as shown in FIG.
In this case, since the severing holder 21 is fixed to the outer housing 19, the communication state among the ejection holes 3, the ejection holes 25, and the guide holes 32 is maintained.

  Thus, when the sealing plate 13 is broken, the fire extinguishing gas in the gas cylinder 11 is guided to the needle tube 45 and ejected, and moves to the valve mounting hole 33 inside the guide shaft 43.

  In this case, the valve mounting hole 33 is hermetically sealed by the control valve 38, and the inner valve 41 is maintained in the closed state, so that the fire extinguishing gas that has moved to the valve mounting hole 33 is on the through hole 31 side. The pressure stays without flowing out to the control valve 38 and the lower part of the seal holder 21.

For this reason, the tear-off holder 21 is pushed up by the pressure of the fire extinguishing gas, and the outer housing 19 moves in conjunction therewith, so that the tear-off holder 21 is separated from the cylinder holder 15, and the needle tube 45 is the breakage portion of the seal plate 13. Pulled out from.
At that time, the long hole 23 moves along the locking pin 24, urging the vertical movement of the outer housing 19, and stops moving when the lower end portion of the long hole 23 contacts the locking pin 24.

  This situation is as shown in FIG. 6, the guide shaft 43 integrated with the tear-off holder 21 moves to the upper part of the through-hole 17, the space of the through-hole 17 increases, and the tear-opening 13 a is opened in the sealing plate 13. Then, the broken opening 13 a communicates with the through hole 17, and the fire extinguishing gas of the gas cylinder 11 is stored in the through hole 17.

  Even in this case, the valve mounting hole 33 is hermetically sealed by the control valve 38, and the inner valve 41 maintains the closed state. Therefore, the fire extinguishing gas that has moved to the valve mounting hole 33 passes through the through hole 31. It stays without flowing out to the side.

  As described above, the present invention temporarily stays in the through-hole 17 of the fire extinguishing gas ejected after the breakage and prevents the outflow. To prevent.

  Further, the residence space of the fire extinguishing gas is slightly larger than that at the time of the blockage in FIG. 5, but is smaller than the filling volume of the gas cylinder 11, so that the jet gas does not drop in pressure, and the fire extinguishes during the residence. Maintain gas liquefaction.

On the other hand, as the outer housing 19 is moved upward, the operation lever 27 attached to the housing 19 is moved, and the outer case 1 engaged with the base portion of the lever 27 is connected to the outer housing 19. At the same time, it moves away from the lower case 10.
Therefore, although the contact terminal 52 moves close to the contact terminal 51, since the conduction state thereof is maintained, power is supplied from the battery 50 to the lamp 48, and the lamp 48 continues to be lit.

  At that time, the outer housing 19 is moved up by the length of the long hole 23 integrally with the tear-off holder 21, and the upper case 1 is also moved together with the outer housing 19 via the operation lever 27. The nozzle hole 25, the jet hole 3 and the guide hole 32 maintain the communication state.

Under such circumstances, the extinguishing gas injector F ₁ is held with one hand while the ejection hole 3 faces the fire source, and the tip of the operation lever 27 is pushed down against the elasticity of the spring 37.
In this way, the operation lever 27 is rotated downward about the pin 28, the protrusion 29 on the lower surface of the lever 27 pushes down the upper end portion of the push rod 35, and the lower end portion of the push rod 35 is the valve. The valve rod 40 is pushed down against the elasticity of the spring 37 by engaging with the upper end of the rod 40.

For this reason, the inner valve 41 moves together with the valve rod 40 and is pushed away from the lower end of the valve body.
As a result, the inside of the control valve 38 becomes conductive, and the lower portion of the valve mounting hole 33 and the through hole 31 communicate with each other through the control valve 38.
And the said fire extinguishing gas moves the inside of the control valve 38, is guide | induced to the guiding hole 32 from the through-hole 31, moves to the ejection hole 3 from the nozzle 26, and is injected to a fire source.

In this case, a part of the injected carbon dioxide is adiabatically expanded after being ejected from the nozzle 25 to form dry ice, which is mixed with gaseous carbon dioxide and injected into the fire.
Therefore, since the temperature around the fire source is lowered and the supply of oxygen to the fire source is shut off, the fire extinguishing action is efficiently performed and the fire is extinguished quickly.

  In this way, the present invention once stagnates the fire extinguishing gas ejected after the rupture, and ejects the nozzle 25 after directing the nozzle 25 to the fire source accurately, so the fire extinguishing gas can be ejected to the fire source accurately and efficiently without waste, Fire extinguishing reasonably and quickly.

On the other hand, when the pressing operation of the operation lever 27 is released when the fire extinguishing gas is ejected, the operation lever 27 is pushed back upward by the elasticity of the spring 37 and the pressing of the valve rod 40 by the push rod 35 is released.
For this reason, the valve rod 40 is pushed back upward by the elasticity of the spring built in the control valve 38, and the inner valve 41 is moved to this, and closes in close contact with the lower end portion of the valve body.

Therefore, the continuity inside the control valve 38 is cut off, the communication between the lower part of the valve mounting hole 33 and the through hole 31 is cut off, the ejection of gas from the nozzle 25 is stopped, and the fire extinguishing gas ejected from the sealed portion However, it stays in the valve mounting hole 33 and the needle tube 45 inside the through hole 17 and the guide shaft 43.
The staying gas is ejected from the nozzle 25 by restarting the pressing operation of the operation lever 27, so that the fire extinguishing gas can be used effectively without waste.

After the extinguishing gas is consumed, the lower case 10 is pulled out from the upper case 1 and rotated while holding the lower portion of the exposed gas cylinder 11, and the screw portion 14 at the mouth of the gas cylinder 11 is connected to the cylinder holder 15. If it is removed from the screw hole 16, the empty gas cylinder 11 can be recovered.
Thereafter, a new gas cylinder 11 is prepared, the screw part 14 at the mouth of the cylinder 11 is screwed into the screw hole 16 and loaded, and the lower case 10 is inserted into the lower end part of the upper case 1. The new gas cylinder 11 can be used.
Thus, the fire-extinguishing gas injector of the present invention is intended to be used repeatedly to realize its effective use.

Further, as an application form of the present invention, a powder container filled with a powder fire extinguishing agent is disposed between the nozzle hole 26 and the guide hole 32 or at an appropriate position, and the fire extinguishing gas ejected from the gas cylinder 11 is guided to the powder container. It is also possible to eject the powder extinguishing agent inside from the nozzle 26.
Furthermore, if pure water or a fire extinguisher liquid is contained in the container and these are sprayed in the form of a mist or foam with the fire extinguishing gas, it is possible to respond to a fire of a chemical or chemical or an electric fire.
