Description

Technical Field

[0001] This utility model relates to fire extinguishing devices, specifically fire extinguishing devices that use ultrafine dry powder as the extinguishing agent. Background Technology

[0002] An ultrafine dry powder fire extinguishing device is a fire-fighting equipment that uses ultrafine dry powder (usually referring to dry powder with more than 90% particle size less than 20 micrometers) as the extinguishing agent. It is instantaneously sprayed through a specific driving method (such as gas-driven or detonation-generated gas) to extinguish fires in a specific protected area. The engine compartment-specific ultrafine dry powder fire extinguishing device has two activation methods: manual (with a start button to prevent accidental explosion) and automatic (with a temperature-sensitive wire). The product requires no piping, is extremely easy to install, has a robust and durable design, is easy to maintain, has low operating costs, and leaves no harmful residues after spraying, making cleaning convenient. It is widely applicable to the engine compartments of cars, buses, trucks, and other motor vehicles. The side-spraying ultrafine dry powder automatic fire extinguishing device, model FFX-ACD0.3-GC, produced by Guanda Co., Ltd., has a cylindrical stainless steel container shell. An external mounting bracket is fixed to the container shell (the bracket is fixed to the container shell by a pin at the rear and a clamp attached to the container shell). The head of the container shell has a screw-on end cap. In practical use, the following shortcomings of this solution were found: First, the separate design of the container shell and the support increases the processing and assembly steps and costs; Second, the connection between the end cap and the shell requires threading, which increases manufacturing costs. In addition, tools can easily scratch the paint on the end cap when installing it. In order not to affect sales, a protective cover of the same color as the product needs to be added to the end cap, which increases costs. Utility Model Content

[0003] The purpose of this invention is to provide an ultrafine dry powder fire extinguishing device with a simple structure and few processing steps.

[0004] To achieve the above objectives, this utility model provides an ultrafine dry powder fire extinguishing device, which consists of a container, a support, a connector, and a nozzle. The container body is an extruded aluminum alloy cylinder, the support is integrally extruded with the container body, and the two ends of the aluminum alloy cylinder are respectively provided with end caps and tail caps, which are interference fit with the cylinder of the container.

[0005] The connector is located on the end cap, and the edge of the end cap is provided with an aluminum alloy connector protective cover. The connector protective cover has an opening to facilitate the passage of the wire harness.

[0006] After adopting the above solution, the main body of this utility model is integrally formed of aluminum alloy, and the two sides of the shell are pressed into the end cap and tail cap, which saves processing steps and costs. Attached Figure Description

[0014] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0015] Please see Figure 1 as well as Figure 2 This utility model discloses an ultrafine dry powder fire extinguishing device, comprising a container 1, a support 2, and a connector 6. The container 1 is an extruded aluminum alloy cylinder, and the support 2 is integrally extruded with the container 1. Figure 1 and Figure 3 The cylindrical shell of container 1 is provided with end caps 3 and tail caps 4 at both ends. The end caps 3 and tail caps 4 are not connected to the cylindrical shell of container 1 by conventional threads. Figure 4 , 5 As shown, end cap 3 and tail cap 4 are interference-fitted with the cylinder of container 1. After end cap 3 and tail cap 4 are pressed into the cylindrical shell, rivets 71 and 72 are pressed into the shell to prevent end cap 3 and tail cap 4 from falling off. A connector 6 is provided on end cap 3. To protect the connector, an aluminum alloy connector protective cover 5 is provided on the edge of end cap 3. The connector protective cover 5 has an opening to facilitate the passage of wire harness.

[0016] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent shape or structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
