Detailed Description

To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 and 2, in one embodiment of the present invention, a fire extinguishing patch is provided, which can be attached to a device requiring fire prevention, and the fire extinguishing patch of the present application includes a housing 10, a fire extinguishing agent layer 20, and an adhesive layer 30, wherein the housing 10 is a fire-retardant housing, the fire extinguishing agent layer 20 is disposed in the housing 10, a substance generated by burning the fire extinguishing agent layer 20 can extinguish a fire, and the adhesive layer 30 is disposed outside the housing 10.

Specifically, the combustible shell 10 in the embodiment of the present application may be an aluminum foil bag, and the adhesive layer 30 may be an adhesive layer, such as a sticker, a double-sided tape, or the like. The adhesive layer 30 is disposed at the outer side of the housing 10 so that the fire extinguishing adhesive can be adhered to the surface of the equipment requiring fire prevention through the adhesive layer 30. This subsides of putting out a fire can glue this subsides of putting out a fire on the equipment that needs the fire prevention through pasting the layer, and through lighting the fire extinguishing agent layer, the material that the burning of fire extinguishing agent layer produced can put out a fire. Because the fire extinguishing agent layer sets up in the casing for whole subsides of putting out a fire are flat structure, and are small, and then make this subsides of putting out a fire 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, simultaneously, because the casing is the fire resistance casing, thereby be favorable to the cyclic utilization of casing.

In some embodiments, the housing 10 includes a base (not shown), the adhesive layer 30 is disposed on the bottom surface of the base, the top of the base is an open structure, and the fire extinguishing agent layer 20 is placed into the base through the opening.

Further, in order to prevent the fire extinguishing agent layer 20 placed in the base from leaking, the housing 10 of the present application further includes a cover plate fitted to the opening of the base, and a gap is provided between the periphery of the cover plate and the inner wall of the opening. When fire is to be extinguished, after the fire extinguishing agent layer 20 in the housing 10 is ignited by the pilot fire, the substances generated by the combustion of the fire extinguishing agent layer 20 are discharged from the gap to extinguish the fire.

In some embodiments, the fire suppressant layer 20 comprises a wrapping layer and an aerosol disposed within the wrapping layer. Specifically, the wrapping layer is a plastic layer or a resin material layer, such as a plastic film, a plastic shell, a resin shell, or the like. The aerosol is one or any combination of powder, granules, tablets or blocks.

The aerosol is wrapped by the wrapping layer, so that the aerosol is conveniently packaged. By igniting the fire extinguishing agent layer 20, the aerosol burns to generate inert gas and metal particles, and the metal particles rob free radicals to block the chain type combustion reaction to extinguish fire, so that the inert gas achieves the auxiliary fire extinguishing effect. In the application, as the aerosol exists in the wrapping layer in the form of powder and/or particles, once the aerosol is ignited, all the aerosol powder and/or aerosol particles directly detonate, so that a large amount of inert gas is released instantly, the oxygen concentration in a space in unit time is reduced, and a better fire extinguishing effect can be achieved.

In some embodiments, the patch of the present application further includes a fuse (not shown) having one end extending into the fire suppressant layer 20 and the other end located outside the housing 10. When the fire extinguishing agent layer is used, the fire extinguishing agent layer can be ignited by igniting the fuse cord, and the fire extinguishing agent layer is convenient to ignite. The fuse may be a heat-sensitive wire, an electronic ignition head, or the like.

In another embodiment, the patch of the present application further comprises 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 electric initiator extends into the fire extinguishing agent layer or is arranged on the surface of the fire extinguishing agent layer, and the controller is used for controlling the electric initiator to ignite the fire extinguishing agent layer.

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 fire extinguishing agent layer.

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-sensing 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 fire extinguishing agent layer. 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-sensing 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 fire extinguishing agent layer.

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

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the protective scope of the invention. Therefore, the protection scope of the patent of the invention should be subject to the appended claims.
