Description

[Detailed description of the invention]

[Technical field to which the invention belongs]

 The present invention relates to the structure of a fire extinguisher.

[0002]

[Prior art]

 As is well known to physicists, due to the influence of gravity, as shown in FIG. 1, the fire extinguisher 1 that is supported and suspended by the hanging groove 51 of the frame 5 explodes due to the temperature rise. The extinguishing agent will fall right below. When observing the cover area A in a circular area on a plane, the eruption amount increases and the fire extinguishing agent is wasted in the central area as it approaches the vertically lower point where the fire extinguisher is installed. Therefore, increasing the spray area of the extinguishant will certainly help extinguishing the fire. Taiwan patent publication No. 57010 aluminum cover fire ammunition has an outer can and an inner can, and works by drawing a stainless wire linked to one safety switch. The design of the fire ammunition does not meet general needs. The basic structure of fire extinguisher is the conventional practice and the provision of Taiwan National Standard No. 1408, which is a fire-fighting article that is filled with a fire-extinguishing agent in a closed glass container and only throws or drops. Taiwanese national standards stipulate that a fire-extinguishing test should be conducted in a windless area within 1 square meter. However, as the fire engineer is familiar with, it can be said that the larger the fire extinguisher cover area, the better the fire extinguishing effect. Publication No. 301228 is a fire extinguisher launcher. Shoot a fire extinguisher with a launch tube. However, it has nothing to do with improving the effectiveness of the fire extinguisher body.

[0003]

[Problems to be solved by the device]

 It is an object of the present invention to provide a fire extinguisher that bursts at elevated temperatures, has a better explosive power, and helps spread the extinguishant. Another object of the present invention is to provide a fire extinguisher with a higher fire extinguishing effect. Yet another object is to provide a fire extinguisher with a second explosion when the fire extinguishing agent splashes on the ground, increasing the fire extinguishing agent coverage area.

[0004]

[Means for Solving the Problems]

 To this end, in the present invention, a sealed filling section is installed in the center of the fire extinguisher. Both ends of the filling part serve as support parts. The central part of the filling part projects outward and has the shape of a rugby ball. As a result, when it bursts due to a rise in temperature, it explodes toward both sides. The present invention further mixes a large number of extinguishing agent spherical bodies with the extinguishing agent. When the spherical body lands on the ground, the fire extinguishing agent can be scattered twice, and the fire-extinguishing cover area is expanded to enhance the fire-extinguishing effect. The above empty spheres can be filled with different extinguishing agents, and at least different types of extinguishing agents can be used for fire extinguishing bullets to expand the application to complex fire types. Further, the structure and features of the present invention are shown as follows.

[0005]

[Embodiment of the invention]

 The fire extinguisher 1 of the present invention can be used to extinguish a fire by throwing it. However, the effect is remarkable when it is suspended and used. 2-5 show the fire extinguisher of the present invention. Like the conventional fire extinguisher, the fire extinguisher of the present invention is hung on a beam, a ceiling, a wall or an appropriate place by using the hanging groove 51 of the frame 5. The fire ammunition 1 of the present invention has an empty, sealed filling 11. The central part thereof projects outward, and the filling part 11 tapers toward both sides, forming one support part 12 each. The extinguishing agent 2 is filled in the filling section 11, and the volume of the extinguishing agent expands due to the temperature rise and vaporizes to increase the internal pressure. The extinguishing agent 2 is scattered by the expansion of the filling portion 11. The support 12 is preferably covered with a metal cover tube 3. There is a neck portion 31 at the end of the cover tube 3 so that the cover tube 3 can be easily attached to the frame 5. It is desirable that the filling portion 11 is made of heat-resistant glass having a low expansion coefficient and that it is ruptured as much as possible when it explodes. Conventional fire extinguishers used safety glass with a high expansion coefficient, but they are not used in the present invention because they easily damage the human body and cause a secondary disaster in a fire. A lot of empty spherical bodies 4 are put in the filling section 11. As shown in FIG. 3, the spherical body 4 is sealed, and the extinguishing agent 41 can be put in advance. In the embodiment shown in FIG. 4, a small hole 42 is opened in the spherical body 4 so that the fire extinguishing agent in the filling portion 11 can flow in. In the example of FIG. 3, the best fire extinguishing effect could be obtained. Conventional fire ammunition uses only one type of fire extinguishing agent, so it is effective only for one type of fire. For example, this is a type A fire. However, in the present invention, different extinguishing agents can be added to the spherical body 4, and this can be applied to the type B fire. In this way, the fire extinguisher of the present invention can be effective in mixed-type fires. The filling section 11 can be filled with various extinguishing agents. It can be applied to liquid, powder, or static fire extinguishing agents. In one embodiment, a liquid containing at least ammonium sulfate, urea, ammonium chloride, and sodium carbonate was used.

After a conventional fire extinguisher explodes, the fire extinguishing agent flies in the direction of the arrow shown in FIG. 1, and it is difficult for the fire extinguishing agent to scatter in both end directions (supporting portions). The cover area is A. In the present invention, since the filling portion 11 has the shape of a rugby ball, it easily scatters toward both ends and its cover area A1 becomes larger. Furthermore, the spherical body 4 made of heat-resistant glass ruptures after landing, and the fire extinguishing agent in the spherical body scatters according to the method shown by the arrow in Fig. 5, so that the cover area A2 becomes larger. For this reason, the large number of spherical bodies 4 and the design in which the center of the filling portion 11 projects in the present invention can increase the cover area of the extinguishant. Although the above two can be carried out independently, a better effect can be obtained by using the two simultaneously. Furthermore, it is desirable that the extinguishing agent 41 of the spherical body 4 be different from the extinguishing agent 2 of the filling portion 11 to further enhance the extinguishing effect. According to the above-mentioned embodiment, the expert carries out many applications such as making the shape of the fire extinguisher spherical, or making one supporting part, or putting many spherical bodies in the filling part without installing the supporting part. can do.

[0007]

[Effect of the invention]

 In the fire extinguisher of the present invention, by making the shape of the filling part a rugby ball shape, the extinguishant can be blown in both directions, and by mixing a spherical body in the filling part, the cover area is expanded and It can be applied to more types of fires.
