Referring to fig. 1 and 2, an embodiment of the present application provides a fire extinguishing patch 100 for attaching to an apparatus requiring fire protection. The fire extinguishing patch 100 includes a first fire extinguishing agent layer 110, a second fire extinguishing agent layer 120, and an adhesive layer 130.

The first fire suppressant layer 110 has a fire suppressant material 111 therein. The fire suppressant material 111 is capable of suppressing a fire. The second fire extinguishing agent layer 120 is disposed inside the first fire extinguishing agent layer 110. The heat generated by the combustion of the second fire suppressant layer 120 enables the release of the fire suppressant material 111. The substances generated by the combustion of the second fire suppressant layer 120 may also extinguish the fire.

Specifically, the adhesive layer 130 may be a glue layer, such as a sticker, a double-sided tape, or the like. The adhesive layer 130 is disposed on the outer surface of the first fire extinguishing agent layer 110 so that the fire extinguishing sticker 100 can be adhered to a surface of an apparatus requiring fire prevention through the adhesive layer 130. Specifically, the adhesive layer 130 may be adhered to the outer surface of the first fire extinguishing agent layer 110.

The fire extinguishing patch 100 can be adhered to the equipment needing fire prevention by the adhesive layer 130. By igniting the second fire suppressant layer 120, the substances generated by the combustion of the second fire suppressant layer 120 can extinguish the fire. The heat generated by the combustion of the second fire extinguishing agent layer 120 releases the fire extinguishing agent material 111 in the first fire extinguishing agent layer 110, so that the fire extinguishing agent material 111 can further extinguish the fire and protect the equipment. Because second fire extinguishing agent layer 120 sets up inside first fire extinguishing agent layer 110, makes the shape of putting out a fire subsides 100 flat, small to put out a fire subsides 100 can be applicable to narrow and small space, conveniently paste inside the equipment that needs the fire prevention, and then can in time put out a fire, and put out a fire subsides 100 low cost.

In one embodiment, the first fire suppressant layer 110 includes a first wrapping layer 112, the first wrapping layer 112 wrapping the fire suppressant material 111. Specifically, the first wrapping layer 112 may be a plastic layer, a resin material layer, or the like, such as a plastic film, a plastic shell, a resin shell, or the like. The liquid fire extinguishing agent may be perfluorohexanone or water or a foam fire extinguishing agent. The second fire suppressant layer 120 is located inside the first wrapping 112.

Specifically, taking the fire extinguishing agent material 111 as perfluorohexanone as an example, since the second fire extinguishing agent layer 120 is located inside the first wrapping layer 112, the first wrapping layer 112 is ruptured by heat generated after the second fire extinguishing agent layer 120 burns, so that the perfluorohexanone is vaporized and sprayed out to extinguish the fire. Further, the perfluorohexanone can absorb heat generated by combustion of the second fire extinguishing agent layer 120 after being sprayed out, so that secondary damage to equipment caused by the heat generated by combustion of the second fire extinguishing agent layer 120 can be prevented.

In one embodiment, the second fire suppressant layer 120 includes a second wrapping layer 122 and an aerosol 121. Specifically, the second wrapping layer 122 may be a plastic layer, a resin material layer, or the like, such as a plastic film, a plastic shell, a resin shell, or the like.

Aerosol 121 is wrapped by second wrapping layer 122, aerosol 121 is conveniently packaged, and liquid extinguishing agent can be prevented from wetting aerosol 121, so that the fire extinguishing effect can be guaranteed.

By igniting the second fire extinguishing agent layer 120, the aerosol 121 burns to generate inert gas and metal particles, the metal particles rob free radicals to block the chain type combustion reaction to extinguish fire, and the inert gas achieves the auxiliary fire extinguishing effect.

In the present embodiment, the aerosol 121 is in the form of one or any combination of powder, granule, tablet or block. It should be understood that when the aerosol 121 is in the form of powder, granule, tablet or block, the specific surface area per unit mass of the aerosol 121 is increased or the density per unit volume of the aerosol 121 is decreased, so that once the aerosol 121 is ignited, the combustion will be rapidly diffused, and a large amount of fire extinguishing substances are instantaneously released in a deflagration manner, thereby increasing the spraying speed and achieving a better fire extinguishing effect.

In one embodiment, the extinguishing patch 100 further includes a fuse (not shown). One end of the fuse extends into the second fire extinguishing agent layer 120 or is disposed on the surface of the second fire extinguishing agent layer 120.

Specifically, the second fire suppressant layer 120 may be conveniently ignited by igniting the fuse, thereby igniting the second fire suppressant layer 120. The fuse may be a heat-sensitive wire, an electronic ignition head, or the like.

In another embodiment, the patch 100 further includes a controller (not shown), a detector (not shown), and an electrical initiator (not shown). The detector is used for detecting fire and sending a fire signal to the controller. One end of the electrical initiator protrudes into the second fire suppressant layer 120 or is disposed on the surface of the second fire suppressant layer 120. The controller is used to control the electrical initiator to ignite the second fire suppressant layer 120.

Specifically, the controller may be an industrial personal computer, a PLC controller, an MCU controller, or the like. The detector may be a temperature sensitive detector. The temperature sensitive detector can detect the occurrence of fire by sensing temperature. The fire signal is a temperature abnormal signal. When the temperature detector senses that the temperature is abnormal, the temperature abnormal signal is sent to the controller, and the controller controls the electric initiator to start, so that the electric initiator ignites the second fire extinguishing agent layer 120.

In other embodiments, the detector may also be a smoke detector. The smoke detector can detect the occurrence of fire by sensing the smoke concentration. The fire signal is a smoke concentration abnormal signal. When the temperature-sensitive detector senses that the smoke concentration is abnormal, the smoke concentration abnormal signal is sent to the controller, and the controller controls the electric initiator to start, so that the electric initiator ignites the second fire extinguishing agent layer 120. The detector may also be a combustible gas detector. The smoke detector can detect the occurrence of fire by sensing the concentration of combustible gas. The fire signal is a combustible gas concentration abnormal signal. When the temperature-sensitive detector senses that the concentration of the combustible gas is abnormal, a combustible gas concentration abnormal signal is sent to the controller, and the controller controls the electric initiator to start, so that the electric initiator ignites the second fire extinguishing agent layer 120.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
