Description

Technology Field

[0001] The present invention relates to a fire extinguisher, and more specifically, to a fire extinguisher with a diffusion-type extinguisher configured to rotate and diffuse the extinguishing liquid during the discharge process, thereby improving the spraying efficiency of the extinguishing liquid and expanding the fire suppression range. Background Technology

[0002] Generally, a fire extinguisher is a device used for initial fire suppression in buildings, vehicles, industrial facilities, as well as general households, and includes a container for storing fire extinguishing liquid or agent inside, and a discharge hose and a nozzle for spraying it outwards.

[0003] These fire extinguishers are structured so that when the user operates the lever after removing the safety pin, the valve opens due to internal compressed gas or a pressurizing device, discharging the extinguishing liquid at high pressure, and the discharged liquid travels along the discharge hose and is sprayed outward through the nozzle.

[0004] However, most conventional fire extinguisher structures use a simple outlet with a straight flow path, so the extinguishing liquid is sprayed only in a straight line, and the spray angle of the sprayed liquid is narrow, so the spraying force and extinguishing range decrease rapidly beyond a certain distance.

[0005] In particular, when a fire spreads to walls or ceilings or occurs over a wide area, there is a problem in that initial fire suppression is difficult because the extinguishing agent is sprayed intensively only on specific parts, making it difficult to rapidly extinguish the entire flame. Additionally, if the extinguishing agent is sprayed while unable to approach the fire source due to the temperature of the flames, there is a problem in that the agent cannot be delivered to the fire source.

[0006] In addition, conventional nozzle structures suffer from significant internal pressure loss, resulting in a problem where pressure is not sufficiently transmitted before the extinguishing liquid is sprayed. Specifically, the internal flow path of the nozzle is a simple cylindrical structure, which causes high flow resistance and consequently limits both spray pressure and diffusion power.

[0007] In addition, most existing diffusion nozzles adopted an air-mixing spraying method, which resulted in a complex structure and difficulties in maintenance. This structure presents problems such as increased manufacturing costs, the possibility of leakage, and inconvenience in assembly. Prior art literature

[0008] Republic of Korea Registered Patent No. 10-1252223 (Registered on April 1, 2013) Republic of Korea Published Patent No. 10-2021-0114126 (Published on September 23, 2021) Republic of Korea Published Utility Model No. 20-2023-0002468 (Published on December 28, 2023) The problem to be solved

[0009] The present invention is proposed to solve the above-mentioned problems and aims to provide a fire extinguisher with a diffusion-type extinguisher capable of maximizing fire extinguishing efficiency by generating rotational force during the process of the extinguishing liquid moving through a discharge hose to improve spray pressure and by spreading the spray angle.

[0011] In particular, the present invention aims to provide a fire extinguisher with a fire extinguishing liquid diffusion type that can lower manufacturing costs due to its simple structure and convenient connection, enables rapid connection in emergency situations, and firmly maintains the state connected to the discharge hose, thereby solving the problem of separation not only in normal positioning but also during the fire extinguishing liquid spraying process. means of solving the problem

[0012] To achieve the above objective, the present invention relates to a fire extinguisher comprising a container for storing fire extinguishing liquid, wherein the fire extinguishing liquid stored in the container moves along a discharge hose and is sprayed through a valve that opens and closes according to the user's removal of a safety pin and operation of a lever.

[0013] A spray pipe connected to the discharge port of the above-mentioned discharge hose, and

[0014] It is characterized by including a diffusion module installed between the discharge hose and the spray pipe to induce rotation of the moving fire extinguishing liquid, thereby spreading the spray angle of the fire extinguishing liquid and increasing the spray pressure.

[0016] In addition, the diffusion module is characterized by being composed of a plate-like body of a predetermined length, with one side in the longitudinal direction being inserted into the discharge hose and the other side in the longitudinal direction being connected to the spray pipe, and the central part in the longitudinal direction being formed into a spiral structure that is twisted at least once to rotate the moving extinguishing liquid.

[0018] At this time, the diffusion module is characterized by having a wedge shape in which the longitudinal side coupled to the spray pipe becomes narrower towards the center, thereby accelerating the speed of the extinguishing liquid when it flows into the spray pipe.

[0020] In addition, the spray pipe is characterized by including a connecting part having an inlet hole to which the diffusion module is coupled, and a spray part having a diffusion structure that gradually expands as it moves toward the spray direction, which sprays the fire extinguishing liquid that has moved in communication with the inlet hole to the outside.

[0022] At this time, the above-mentioned connecting part is characterized by having a plurality of annular unidirectional ratchet protrusions protruding outwardly to prevent disengagement with the discharge hose.

[0024] In addition, the spraying part is characterized by being formed such that the edge of the longitudinal end portion, where the extinguishing liquid is sprayed outward, has a predetermined curvature toward the outside, thereby homogenizing the distribution of the sprayed extinguishing liquid.

[0026] In addition, the above-mentioned connecting part is characterized by being formed to have a relatively smaller diameter compared to the above-mentioned injection part and being introduced into the above-mentioned discharge hose. Effects of the invention

[0027] The present invention, as described above, has a spray diffusion effect resulting from the formation of a rotational flow of the fire extinguishing liquid. When the fire extinguishing liquid passes through the diffusion module, it forms a rotational flow along a twisted spiral structure. Through this, the sprayed fire extinguishing liquid has a swirling diffusion pattern rather than a simple straight line, thereby expanding the spray range. Consequently, the fire extinguishing liquid is evenly sprayed not only to the center of the flame but also to the periphery, thereby enabling the efficient suppression of a fire over a wide area.

[0029] In addition, the present invention has the effect of increasing the velocity of the discharged extinguishing liquid by having the longitudinal side of the diffusion module form a wedge-shaped structure, thereby improving the spray distance and spray intensity even at the same container pressure of the extinguishing liquid, and the spray pipe is formed such that the diameter gradually increases along the direction in which the extinguishing liquid is discharged, thereby smoothly transitioning the flow of the sprayed extinguishing liquid and suppressing vortices or unstable spray phenomena.

[0031] In addition, the present invention is structured such that the rim of the spray pipe has outward curvature, thereby dispersing the flow path of the sprayed extinguishing liquid. This allows for uniform atomization and diffusion of the extinguishing liquid, resulting in the effect of spraying evenly over a wide area without loss of central pressure in the direction of spraying. Consequently, a larger area can be covered with the same amount of extinguishing liquid, thereby improving extinguishing efficiency.

[0033] In addition, the unidirectional ratchet protrusion formed on the outer surface of the connection part can maintain a secure connection with the discharge hose even against vibrations or recoil generated during spraying, thereby preventing detachment or leakage during spraying and ensuring user safety.

[0035] In addition to the above objectives, other objectives and features of the present invention will become apparent through the description of embodiments with reference to the accompanying drawings.

[0037] Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as generally understood by those skilled in the art to which the present invention pertains. Terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an ideal or overly formal sense unless explicitly defined in this application.

[0039] Hereinafter, a preferred embodiment of a fire extinguisher with a diffusion-type extinguishing liquid according to the present invention will be examined in detail with reference to the attached drawings.

[0040] First, the fire extinguisher (1) according to the present invention is a fire extinguisher that has a container (10) for storing fire extinguishing liquid, and in which the fire extinguishing liquid stored in the container moves along a discharge hose (20) and is sprayed through a valve that opens and closes according to the user's removal of a safety pin and operation of a lever, the fire extinguisher includes a spray pipe (30) coupled to a discharge port (21) of the discharge hose (20), and a diffusion module (40) installed between the discharge hose (20) and the spray pipe (30) to induce rotation of the moving fire extinguishing liquid to spread the spray angle of the fire extinguishing liquid and increase the spray pressure.

[0042] The above container (10) and discharge hose (20) are identical in structure to a general fire extinguisher, wherein the container (10) has a predetermined volume and stores a fire extinguishing liquid or fire extinguishing agent inside, and the discharge hose (20) is installed on the upper side of the container (10) so that when a user removes the safety pin and operates the lever, the fire extinguishing liquid stored in the container (10) is discharged to the outside through the discharge hose (20), and at this time, the discharge hose (20) is made of a flexible material so as to change the direction of discharge of the discharged fire extinguishing liquid.

[0044] The above-mentioned spray pipe (30) is coupled to the discharge port (21) of the discharge hose (20) and includes a connecting part (31) having an inlet hole (311) to which the diffusion module (40) is coupled, and a spray part (32) that communicates with the inlet hole (311) and sprays the moving fire extinguishing liquid to the outside, having a diffusion structure that gradually expands as it moves toward the spray direction.

[0045] These spray pipes (30) are connected to the discharge hose (20) and serve as a passage for transporting and ejecting fire extinguishing liquid. They are formed of a synthetic resin or metal material capable of withstanding internal pressure, and the inner surface through which the fire extinguishing liquid travels may be polished or formed with an inert coating layer to minimize friction loss.

[0046] The above-mentioned spray pipe (30) is connected to the discharge port (21) through which the extinguishing liquid is discharged from the discharge hose (20) to discharge the moved extinguishing liquid to the outside, and a diffusion module (40) described later is installed inside to spread the discharge angle of the discharged extinguishing liquid and increase the discharge pressure.

[0047] The above-mentioned connecting part (31) is connected to the discharge port (21), and in order to maintain the connected position and prevent disconnection from the discharge hose (20), a plurality of unidirectional ratchet protrusions (312) protruding outward from the outer surface are formed at intervals along the length direction of the connecting part (31), and the unidirectional ratchet protrusions (312) are formed to protrude outwardly in an annular shape from the outer surface of the connecting part (31).

[0048] Through the unidirectional ratchet protrusion (312) formed as described above, the connection with the discharge hose (20) can be maintained even during the process of moving the extinguishing liquid at high pressure, and at the same time, the spray pipe (30) can be rotated so that the extinguishing liquid can be discharged to a desired location.

[0049] In addition, the above-mentioned connecting part (31) has a relatively smaller diameter than the above-mentioned spraying part (32) and is formed in the shape of a hollow tubular body, receiving fire extinguishing liquid while inserted into the discharge port (21) of the discharge hose (20), and a sealing or packing may be provided to prevent the fire extinguishing liquid moving at this time from leaking out.

[0050] The above-mentioned spraying part (32) is configured to spray fire extinguishing liquid to the outside, and is connected to the above-mentioned connecting part (31) so that the fire extinguishing liquid moves and is sprayed to the outside. It is formed to have a relatively larger diameter compared to the above-mentioned connecting part (31), so that the fire extinguishing liquid moving through the above-mentioned connecting part (31) at high pressure moves to the spraying part (32) having a relatively wider diameter, and then expands, and the spraying angle expands as it is sprayed to the outside.

[0051] To this end, the spraying part (32) is formed in the shape of a trumpet, with an internal diameter that increases as it faces the end where the digestive fluid is discharged, so that the diffusion range widens as it faces the end where the digestive fluid is discharged.

[0052] Meanwhile, the above-mentioned spraying part (32) is formed such that the edge (321) of the longitudinal end portion where the extinguishing liquid is sprayed outward has a predetermined curvature toward the outside, thereby uniformizing the distribution of the sprayed extinguishing liquid.

[0053] That is, the rim (321) of the spraying part (32) is formed to have a curvature that extends outward, so that the extinguishing liquid that has moved along the inner surface of the spraying part (32) is sprayed outwardly along the rim (321) formed to have a curvature that extends outward, thereby spreading the spray angle.

[0054] By doing this, the rim (321) having an outwardly extending curvature disperses the flow path of the digestive fluid and uniformly atomizes and diffuses the digestive fluid, allowing it to be sprayed evenly over a wide area without central pressure loss.

[0056] The above diffusion module (40) is positioned between the discharge hose (20) and the spray pipe (30) to rotate the extinguishing liquid moved from the discharge hose (20), thereby improving the discharge angle of the extinguishing liquid and increasing the discharge speed to widen the discharge range.

[0057] The diffusion module (40) for this purpose is made of a plate-like body of a predetermined length, one side in the longitudinal direction is inserted into the discharge hose (20), the other side in the longitudinal direction is connected to the spray pipe (30), and the central part in the longitudinal direction is made of a spiral structure formed by twisting at least once to rotate the moving extinguishing liquid.

[0058] In this diffusion module (40), the fire extinguishing liquid moving from the discharge hose (20) moves to the spray pipe (30) while rotating along the outer surface of the diffusion module (40) through a spiral twist structure, and accordingly, the fire extinguishing liquid has a swirling flow, and the spray angle is expanded by centrifugal force during spraying and the spray pressure is increased.

[0059] Here, the length of the diffusion module (40) can be made longer or the number of twists can be increased, but the length of the diffusion module (40) can be adjusted by considering the distance between the discharge hose (20) and the injection pipe (30), and the number of twists can be adjusted according to the total length of the diffusion module (40).

[0060] In addition, the diffusion module (40) can form an annular groove (not shown) in the shape of a spiral corresponding to the shape of the diffusion module (40) on the inner surface of the inlet hole (311) of the spray pipe (30) to more firmly fix the diffusion module (40) inside the spray pipe (30), thereby preventing detachment even under high pressure and vibration when spraying fire extinguishing liquid.

[0061] By forming a fixing jaw (not shown) on the injection pipe connection side that contacts the other end of the diffusion module (40) in the longitudinal direction, the detachment can be prevented.

[0062] These diffusion modules (40) may be made of aluminum alloy or stainless steel with excellent heat resistance and corrosion resistance, but are not limited to the aforementioned materials.

[0063] Meanwhile, one end of the longitudinal direction of the diffusion module (40) that is connected to the injection pipe (30) is formed in a wedge shape that narrows toward the center. This wedge structure gradually contracts the flow of the moving extinguishing liquid to concentrate the flow energy, thereby strengthening the rotational force, and thereby allowing the extinguishing liquid to be sprayed over a longer distance with a wider diffusion angle and higher injection pressure when sprayed.

[0064] Therefore, the above diffusion module (40) can achieve rotation and diffusion effects of the digestive fluid using only a simple spiral plate shape, even without using a complex internal flow path structure or porous material.

[0065] In addition, the diffusion module (40) can be molded integrally with the injection tube (30), which simplifies assembly and fixation and has the effect of reducing manufacturing costs and improving durability.

[0067] As described above, the present invention has been explained by specific details such as specific components, limited embodiments, and drawings; however, this is provided merely to aid in a more comprehensive understanding of the invention, and the invention is not limited to the above embodiments. A person skilled in the art can make various modifications and variations from this description.

[0069] Accordingly, the scope of the present invention should not be limited to the described embodiments, and all things equivalent to or having equivalent variations to the claims set forth below, as well as the claims set forth below, shall be considered to fall within the scope of the concept of the present invention.
