Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing equipment, in particular to a layered hot aerosol device. Background Art

[0002] An aerosol fire extinguishing device is a small, miniature fire extinguishing device that utilizes a solid aerosol as a charge. This charge is ignited using a heat-sensitive wire or other initiator, instantly generating a large amount of hot aerosol fire extinguishing agent. The solid fire extinguishing agent in the aerosol fire extinguishing device is electrically activated, undergoing a redox reaction to form a large amount of agglomerated fire-extinguishing aerosol, primarily composed of nitrogen dioxide (N2), a small amount of carbon dioxide (CO2), and solid metal salt particles. The metal salt particles absorb significant amounts of heat at high temperatures, undergoing physical endothermic processes such as melting and vaporization. This lowers the flame temperature, which then radiates to the combustion surface of the combustible material, vaporizing the combustible molecules. This reduces the heat required to break down the vaporized combustible molecules into free radicals, thereby suppressing the combustion reaction rate.

[0003] The charge inside the existing hot aerosol device is a whole. When it ignites, the reaction speed is low due to its large volume and small contact area with the ignition end of the fuse, thereby reducing the amount of aerosol sprayed per unit time and thus reducing the fire extinguishing effect. Summary of the Invention

[0004] In order to solve the above technical problems, the utility model uses an annular inner cylinder and a cylindrical inner cylinder to divide a whole medicine block into two parts.

[0010] Preferably, the annular inner cylinder includes an outer cylinder wall, an inner cylinder wall coaxially arranged inside the outer cylinder wall, and a bottom plate arranged at the bottom edge of the outer cylinder wall.

[0011] Preferably, the bottom of the cylindrical inner cylinder is provided with a base, and a threaded groove matched with the inner cylinder wall is formed in the inner wall of the base.

[0012] Preferably, the inner bottom wall of the shell is provided with a fixing plate, and a plurality of fixing holes corresponding to the fixing holes are formed in the surface of the fixing plate.

[0013] Preferably, the side wall of the annular inner cylinder and the cylindrical inner cylinder is provided with a socket, the top of the top cover is provided with a metal joint, and the bottom of the shell is provided with an electric plug.

[0014] Preferably, the detonation assembly comprises a physical lead extending through the metal joint and sequentially extending through the annular inner cylinder and the cylindrical inner cylinder to the gap between the annular inner cylinder and the shell, a branch lead arranged at the end of the physical lead and extending to the inside of the cylindrical inner cylinder through the socket, and an electric lead arranged at the end of the physical lead and connected with the electric plug by bypassing the side wall of the fixing plate.

DETAILED DESCRIPTION

When a fire occurs at the place of use, the detonation assembly provided can simultaneously ignite the medicine blocks inside the annular inner cylinder 20 and the cylindrical inner cylinder 30, so that the two parts of the medicine blocks are ignited at the same time. Moreover, since the two parts of the medicine blocks are relatively small, the ignited reaction area will be increased, which facilitates the medicine blocks to react more quickly, can speed up the aerosol spray speed, and thus improve the fire extinguishing speed, solving the problem in the prior art that the entire large volume of medicine blocks is placed in the equipment, which will result in a slow reaction speed when ignited, resulting in a slow aerosol spray speed, resulting in a slow fire extinguishing speed.

[0032] Reference Figure 4 It should be noted that an annular cover plate 210 is installed on the top of the annular inner cylinder 20, a circular cover plate 310 is installed on the top of the cylindrical inner cylinder 30, and a top cover 110 is attached to the top of the outer shell 10 by threaded glue. In order to allow the aerosol generated after the combustion of the medicine block to be sprayed out, it is also necessary to open spray holes on the surfaces of the top cover 110, the annular cover plate 210 and the circular cover plate 310. After the medicine blocks are placed in the inner cavities of the annular inner cylinder 20 and the cylindrical inner cylinder 30 respectively, the annular cover plate 210 and the circular cover plate 310 are respectively installed on the top of the annular inner cylinder 20 and the cylindrical inner cylinder 30 to seal the medicine blocks. Finally, the top cover 110 is installed on the top of the outer shell 10 to complete the assembly. When the medicine blocks are ignited to react and produce aerosols, the aerosols will be sprayed out through the spray holes on the surfaces of the annular cover plate 210, the circular cover plate 310 and the top cover 110, thereby playing a fire extinguishing function.

[0033] Among them, tin foil is pasted on the lower surface of the top cover 110, the upper surface of the annular cover plate 210 and the upper surface of the circular cover plate 310, and silicone pads are provided on the inner side wall and the inner bottom wall of the outer shell 10. The tin foil can block the medicine blocks inside the annular inner cylinder 20 and the cylindrical inner cylinder 30 to prevent the medicine blocks from leaking out. When the medicine blocks are ignited and react, they will be sprayed out through the spray hole and break through the tin foil; at the same time, the silicone pad can limit the annular inner cylinder 20 and the cylindrical inner cylinder 30 to prevent the annular inner cylinder 20 and the cylindrical inner cylinder 30 from shaking inside the outer shell 10.

[0034] Reference Figure 5 As a preferred technical solution of this embodiment, the annular inner cylinder 20 is composed of an outer cylinder wall 220, an inner cylinder wall 230 and a bottom plate 240. The inner cylinder wall 230 is coaxially arranged inside the outer cylinder wall, and the bottom plate 240 is arranged at the bottom edge of the outer cylinder wall 220. A base 320 is provided at the bottom of the cylindrical inner cylinder 30. The inner wall of the base 320 is provided with a threaded groove that matches the inner cylinder wall 230. During installation, the inner cylinder wall 230 and the base 320 are threadedly connected with the threaded groove, thereby realizing an effective connection between the inner cylinder wall 230 and the base 320.

[0035] Further, refer to Figure 8 A fixing plate 60 is provided on the bottom wall of the outer shell 10, and mounting holes are provided at the bottom of the bottom plate 240 and the base 320. A plurality of fixing holes corresponding to the fixing holes are provided on the surface of the fixing plate 60. When assembling the equipment, the inner cylinder wall 230 can be threadedly installed on the inner side of the base 320, and then the bolts are passed through the fixing holes on the surface of the fixing plate 60 and continue to pass through the mounting holes on the bottom plate 240 and the base 320. Finally, the nuts are installed on the screwed-in ends of the bolts, so that the annular inner cylinder 20 and the cylindrical inner cylinder 30 can be installed inside the outer shell 10.

[0036] Reference Figure 6 、 Figure 7 、 Figure 9As a preferred technical solution of this embodiment, the side walls of the annular inner cylinder 20 and the cylindrical inner cylinder 30 are both provided with jacks, the top of the top cover 110 is provided with a metal joint 70, and the bottom of the outer shell 10 is provided with an electric plug 120. Furthermore, the detonation assembly includes a physical lead 80, a branch lead 810 and an electrical lead 820. The physical lead 80 passes through the metal joint 70 and sequentially passes through the annular inner cylinder 20 and the cylindrical inner cylinder 30 to extend to the gap between the annular inner cylinder 20 and the outer shell 10. The branch lead 810 is arranged at the end of the physical lead 80 and extends to the inside of the cylindrical inner cylinder 30 through the jack. The electrical lead 820 is arranged at the end of the physical lead 80 and extends to the inside of the cylindrical inner cylinder 30 through the jack. It bypasses the side wall of the bottom plate 240 and is connected to the electric plug 120. When a fire occurs at the place where the product is used, when the fire ignites the physical lead 80, the physical lead 80 will burn and continue to ignite the branch lead 810 connected to it. Therefore, the branch lead 810 can ignite the medicine blocks inside the annular inner cylinder 20 and the cylindrical inner cylinder 30, causing the medicine blocks to react and produce aerosols; if the fire does not ignite the physical lead 80 in time, if the staff finds this situation, they can also start the electric plug 120 through the external switch to ignite the electric lead 820, and the physical lead 80 can still be ignited through the electric lead 820 to ignite the medicine blocks.

[0037] Reference Figure 3 As a preferred technical solution of this embodiment, the gap between the annular inner cylinder 20 and the cylindrical inner cylinder 30 and the gap between the annular inner cylinder 20 and the outer shell 10 are both provided with a heat absorption component, and the heat absorption component includes a plurality of ceramic beads 40, and the plurality of ceramic beads 40 are respectively filled in the gap between the annular inner cylinder 20 and the cylindrical inner cylinder 30 and the gap between the annular inner cylinder 20 and the outer shell 10. A steel wire mesh 50 for pressing the ceramic beads 40 is provided on the top of the annular inner cylinder 20 and the cylindrical inner cylinder 30. When the explosive block is ignited and reacts to generate aerosol, it will generate heat. At this time, the ceramic beads 40 arranged on the outside of the annular inner cylinder 20 and the cylindrical inner cylinder 30 can absorb the generated heat to prevent the internal temperature of the equipment from being too high and affecting the normal fire extinguishing work. In addition, the provided steel wire mesh 50 can squeeze and fix the filled ceramic beads 40 when assembling the equipment.

[0038] The working principle of the present invention is as follows: first assemble the aerosol device, and divide the original large medicine block into two smaller medicine blocks, which are then placed inside the annular inner cylinder 20 and the cylindrical inner cylinder 30 respectively. When a fire occurs at the scene, when the fire ignites the physical lead 80, the physical lead 80 will burn and continue to ignite the branch lead 810 connected to it. Therefore, the medicine blocks inside the annular inner cylinder 20 and the cylindrical inner cylinder 30 can be ignited through the branch lead 810, causing the medicine blocks to react and produce aerosols. If the fire does not ignite the physical lead 80 in time, if the staff finds this situation, they can also start the electric plug 120 through the external switch to ignite the electric lead 820, and the physical lead 80 can still be ignited through the electric lead 820 to ignite the medicine blocks, which can also achieve the purpose of simultaneously igniting the medicine blocks inside the annular inner cylinder 20 and the cylindrical inner cylinder 30, so that the two parts of the medicine blocks are ignited at the same time. Since the two parts of the medicine block are relatively small, the reaction area of ​​​​the ignition will be increased, so that the medicine block can react more quickly and completely, which can accelerate the aerosol injection speed and thus improve the fire extinguishing speed. This solves the problem in the prior art that placing the entire large volume of medicine block in the equipment will result in a slow reaction speed when ignited, resulting in a slow aerosol injection speed, thereby leading to a slow fire extinguishing speed.

[0039] The above-described embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
