Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an automatic/manual fire extinguisher.

(Conventional technology) Conventional automatic/manual fire extinguishers are those that have a cylindrical body that is pressurized with extinguishing agent, or automatic fire extinguishers that have a built-in high-pressure gas cylinder that is filled with nonflammable fluid at high pressure. Since there was a need to house a handler for a manual fire extinguisher, the shape of the cylinder body had to be designed with durability, pressure resistance, corrosion resistance, etc. in mind, and special processing was required to make it larger.

Furthermore, in conventional automatic/manual fire extinguishers, the extinguishing agent jetting nozzle is of a hose type, so there are restrictions on where it can be installed, making it extremely difficult to mount it on the ceiling or wall of a room.

In addition, conventional fire extinguishers have a nozzle for spraying extinguishing agent that can be oriented freely and fixed in a position facing a predetermined location, making it impossible to spray extinguishing agent.

(Problems to be Solved by the Invention) The present invention is extremely simple in that the cylindrical body constituting the fire extinguisher is simply formed by cutting an existing metal pipe (usually made of aluminum acid) into a predetermined length. Using a manufacturing process, an automatic and manual sensor unit is attached to the outside of the cylinder, making it extremely simple compared to conventional cylinders, and filling the cylinder with fire extinguishing liquid. Since we limited ourselves to containers made of flexible synthetic resin, the overall shape of the cylinder became more compact.
When refilling the fire extinguishing liquid after it has been used or after a certain period of time has elapsed, it is a cartridge type and can be simply replaced with a new one.The conditions required for the cylinder body are significantly reduced compared to conventional cylinder bodies. However, it is easy to manufacture and can be manufactured at low cost.

Furthermore, in the fire extinguisher of the present invention, the extinguishing liquid spray nozzle can be bent in a predetermined direction by hand, and can be fixed while facing in a predetermined direction, so that the nozzle can be directed in the most suitable direction for extinguishing indoor fires. It also has the advantage of being able to be mounted on the ceiling or wall while selecting the desired location.

In addition, compared to conventional fire extinguishers, the fire extinguisher of the present invention allows you to extinguish a fire by adjusting the spray nozzle in any direction with your fingers while holding it like a haezuka cannon, so you can aim with certainty and
Even though it is heavy, it is easy to carry, and its unique shape makes it interesting to use as an interior decoration.

(Means for Solving the Problems) The present invention provides a flexible synthetic resin container filled with a fire extinguishing agent in a cylindrical body having openings on both left and right sides, and filling an injection port. Insert the tube into the left and right openings of the cylindrical body, and screw the front and rear hooks that have insertion holes in the center to protect the bendable pipe, which has an insertion hole in the center and a recess in the surrounding wall. The cover part is inserted into the insertion hole with the inlet part of the container sticking out, and then glued to the front bend, one end of the bendable pipe is screwed to the inlet part of the container, and the other end of the bendable pipe is screwed onto the inlet part of the container. At the same time, one end of the conduit that connects to the automatic and manual sensor section is connected to the insertion hole in the rear part, and the high pressure that constitutes the automatic and manual sensor section is connected to the injection nozzle. This fire extinguisher is an automatic/manual fire extinguisher characterized by a firing pin operation part that breaks the sealing plate of a fire extinguishing agent injection pump filled with a nonflammable fluid, and a trigger attached to the cylinder body.

(Example) A is an automatic and manual fire extinguisher of the present invention, which has the following configuration. 1 is a hollow cylindrical body formed by cutting a pipe made of aluminum or other material into a predetermined size, and the cross-sectional shape is usually circular or not limited. As described above, the cut cylinder 1 has left and right openings 2.2' formed at both ends thereof. 3.3' is a threaded part carved into the outer peripheral edge of both openings 2.2'; 4 is a container made of flexible synthetic resin filled with fire extinguishing liquid; The inner surface of the cylinder l and the container 4
Even if the outer surface of the cylinder comes into contact with the cylinder, no chemical reaction will occur because the extinguishing liquid is not directly filled inside the cylinder. An injection port 5 is formed at the tip of the container 4.

5' is a screw provided on the outside of the inlet part 5, 6 is a front part with a fitting hole 7 formed in the center and a female screw 8 formed on the inside surface;
Reference numeral 9 designates a rear hinge having a fitting hole 10 formed in the center and a female thread 11 formed on the inner surface. Reference numeral 12 denotes a cover part, which has a fitting hole 13 formed in the center, is hollow on the inside, and has a cut-shaped recess 15 formed in the surrounding wall part 14. 16 is always inserted into the cover part 12. A female screw 17 is cut into the inner surface of the end to be screwed into the screw 5' of the container 4, and a screw 18 is also provided on the outer surface of the other end. It is a bendable pipe.

19 is an injection nozzle provided with a screw 20 that is screwed into the screw 18 of the pipe 16, a gasket 21 is inserted, and an injection hole 22 is provided, and when the nozzle 19 and the pipe 16 are screwed together as described above, Both members can be connected.

b is an automatic/manual sensor unit, which is connected to a fire extinguishing agent injection cylinder 2 filled with nonflammable fluid at high pressure.
3, and also includes a firing pin operation part 24 for breaking the sealing plate of the cylinder 23. 25 is a conduit whose one end is connected to the sensor section and the other end is connected to the insertion hole 10 of the rear cover 9, respectively. 26 is a cover that covers the rear bend 9 and the conduit 25; 27 is a trigger that straddles the cylinder l; its upper part is connected to the firing pin operating part 24; and is pulled by a spring; 28 is a trigger of the cylinder l; It is an arm angle whose both ends are attached to an angle attachment fitting 32 wrapped around the outer periphery. 29 is a ceiling portion, 30 is a wall surface portion, and 31 is a resting portion for the fire extinguisher a.

(Function) In order to directly mount the fire extinguisher a of the present invention, which has been assembled from the disassembled state shown in FIG. 1 as shown in FIG. It is sufficient to attach it via the angle fitting 32 as shown in the figure. and nozzle 19
When it is desired to apply a predetermined force in two directions suitable for extinguishing a fire, the neck of the nozzle 19 is bent from any recess 15 of the cover group 12, and the nozzle 19 can be easily bent depending on the characteristics of the pipe 16. In this case, the sensor section may be installed in such a way that it can reliably sense a predetermined amount of heat generated in the event of a fire. Furthermore, when installing the fire extinguisher a on the back side of the ceiling part 29, it is sufficient to install it with the nozzle 19 and the sensor part protruding from the ceiling part 29, as shown in Figure 5. When installing a on the surface of the wall section 30, as shown in Figure 6, the nozzle 19 should be oriented in a direction suitable for extinguishing fires, and the sensor section should also be installed so that it can reliably detect high heat during a fire. Of course. The arm angle 28 is removed and set when attached to each surface, such as 0 and above, which are attached to the back of the wall section 30 in the same manner as when attached to the back of the ceiling section 29. When there is a mounting part 31 attached to the ground wall surface part 30, a fire extinguisher a may be mounted thereon as shown in FIG. Although not shown, in the fire extinguisher a of the present invention, a hook driven into the wall surface portion 30 via the arm angle 28 can also be hooked onto a tool.

Furthermore, to manually operate the fire extinguisher a of the present invention, hold the fire extinguisher a with both hands like a bazooka, point the nozzle 19 with your fingers toward the fire extinguishing target point, and pull the trigger 27. . The moment the trigger 27 is pulled, the firing pin operating section 24
breaks the sealing plate of the cylinder 23, and the high-pressure nonflammable fluid filled in the cylinder 23 flows into the cylinder 1 from the conduit 25, compressing the container 4. Due to this compression action, the extinguishing liquid being filled ruptures the packing in the nozzle 19 from the pipe 16, and the extinguishing liquid is injected from the injection hole 22. Note that the spray direction can be adjusted freely using your fingers.

Next, when the fire extinguisher a is attached to the ceiling part 32 or the wall part 30, the automatic extinguishing method is switched to, but the firing pin operates at the sensor part and ruptures the high-pressure gas cylinder 23. When the fuse melts, the fire extinguishing liquid is injected from the injection hole 22 of the nozzle 19 in the same process as when the trigger 27 is pulled, a so-called manual process.

The used container 4 can be easily removed from the cylindrical body 1 by removing the front flap 6 and the like from the cylindrical body 1.

Also, when replacing the container 4 filled with the extinguishing liquid, the same operation as described above may be performed.

(Effects) (1) In the fire extinguisher of the present invention, the cylindrical body is usually made of aluminum pipe and is simply cut to a specified size and the front and rear bends are set in both openings, so the processing of the fire extinguisher is much easier than that of conventional fire extinguishers. It has the advantage that it can be manufactured at a low cost because it is significantly simpler than a container.

(2) Furthermore, the present invention employs a method in which the sensor section is placed externally and the compressive energy of the high-pressure nonflammable fluid filled in the gas cylinder for blowing out extinguishing agent is introduced into the foil body through the conduit. This has the advantage that the internal space of the sensor section can be reduced and the interior of the cylinder body can be used more effectively.

(3) Also, in the present invention, the neck of the nozzle can be bent in any direction with the fingers and arranged vertically downward, making it easy to attach to ceilings or walls, and the unique shape makes it suitable for interior decoration. It also has many excellent advantages, such as fully demonstrating its functions and greatly increasing the fun.
