[0002] Aerosol fire extinguishing is a new fire extinguishing method in the fire fighting field, which is different from traditional carbon dioxide fire extinguishing, dry powder fire extinguishing, and water-based fire extinguishing. It is a new breakthrough in the fire fighting field. Aerosol fire extinguishing combines high-efficiency gas-producing aerosol agents with fire extinguishing particle generators, and uses the heat and power of the aerosol agent to generate fire extinguishing gas to decompose the fire extinguishing particle generator to release high-efficiency fire extinguishing particles. It is superior to traditional fire extinguishers in portability, safety and fire extinguishing ability, and is a full-flooding method for efficient fire extinguishing.
[0003] Chinese patent CN201810230031.4 discloses an aerosol fire extinguishing patch, including a plurality of fire extinguishing sheets, wherein the fire extinguishing sheets are S-type aerosol fire extinguishing agents in sheet form; the plurality of fire extinguishing sheets are arbitrarily combined and spread on the front of a substrate; a bonding layer is provided on the back of the substrate; and a layer of heat-sensitive ignition powder is covered on the top of the fire extinguishing sheet. The fire extinguishing trigger is sensitive and reliable in operation, and the fire source can be extinguished instantly and effectively, and the fire source can be extinguished at the initial stage, minimizing the loss caused by the fire; automatic fire extinguishing can be achieved without power supply, and it is easy to install and use.
[0004] However, in this technical solution, the fire extinguishing piece is in direct contact with the outside. During the deflagration process, its open flame can easily cause other combustibles to burn, aggravating the fire. Utility Model Content

By arranging a metal foil on the outside of the aerosol confusing column to block the outward diffusion of open flames, the problem of the aerosol fire extinguishing patch causing the fire to worsen due to its own deflagration in the early stage of fire extinguishing can be solved.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] An aerosol fire extinguishing patch comprises a soft substrate, both sides of which are provided with adhesive layers, one side of the soft substrate is provided with a plurality of aerosol fire extinguishing powder columns, the aerosol fire extinguishing powder columns are fixed to the soft substrate through the adhesive layer, and the outer side of the aerosol fire extinguishing powder column is also coated with a layer of heat-sensitive ignition powder layer; it is characterized in that it also includes a metal foil arranged at the top of the aerosol fire extinguishing powder column for preventing open flames from spreading outward.
[0008] As an improvement, the metal foil is copper foil.
[0009] As an improvement, the soft substrate is a circular structure.
[0010] As an improvement, the soft substrate is a foam substrate.
[0011] As an improvement, a plurality of aerosol fire extinguishing powder columns are evenly distributed in an array on the soft substrate.

[0013] As an improvement, the cross section of the aerosol fire extinguishing powder column is a square structure, and is arranged in a linear array on the soft substrate.
[0014] As an improvement, the aerosol fire extinguishing agent column is individually evenly distributed on the soft substrate.
[0015] As an improvement, the aerosol fire extinguishing powder column is formed by compression.
[0016] The beneficial effects of the utility model are:
[0017] (1) The utility model solves the problem of the fire situation being aggravated by the aerosol fire extinguishing patch itself deflagration in the early stage of fire extinguishing by arranging a metal foil on the outside of the aerosol confusing charge to block the open flame from spreading outward.
[0018] (2) The utility model can adapt to fire extinguishing patches of different sizes by arranging a variety of specifications of the charge column layout, thereby improving the versatility of the aerosol fire extinguishing charge column.
[0019] In summary, the utility model has the advantage that there is no large amount of open flame leakage in the initial stage of the fire extinguishing patch. BRIEF DESCRIPTION OF THE DRAWINGS
