The length of the main shell is 3-20 times of the thickness, and the width of the main shell is 3-20 times of the thickness. Specifically, the main housing 20 includes a first housing 21 and a second housing 23, one end of the first housing 21 is hinged to one end of the second housing 23, and the other end of the first housing 21 and the other end of the second housing 23 can be clamped to each other. It will be appreciated that the shape of main housing 20 is not limited, and in other embodiments, the cross-section of main housing 20 may be provided in a regular shape such as a circle, an ellipse, a polygon, or other irregular shapes as desired.
Thus, the first housing 21 and the second housing 23 can be fastened to form a sealed accommodating cavity, and the fire extinguishing assembly 40 is enclosed in the accommodating cavity. Since the first housing 21 and the second housing 23 are connected to each other in a hinged manner, after the fire extinguishing apparatus 100 is started, the first housing 21 and the second housing 23 are prevented from being completely separated and damaging electrical devices under the action of internal pressure.
Further, an injection port 25 is formed between the first housing 21 and the second housing 23, and the injection port 25 is used for communicating the accommodating cavity with the external environment under the action of a first preset pressure.

Wherein the second preset pressure is greater than the first preset pressure.
Thus, the pressure relief opening 27 can communicate the accommodating cavity with the external environment under the action of the second preset pressure. After the fire extinguishing device 100 is started, when the pressure in the accommodating cavity is gradually increased to a second preset pressure, the fire extinguishing agent 43 in the fire extinguishing assembly 40 can be sprayed out from the pressure relief port 27 to properly reduce the pressure in the accommodating cavity while being sprayed out from the spray port 25, so that the safety requirement of the fire extinguishing device 100 is met.
In one embodiment, the pressure relief member is a pressure relief diaphragm covering the pressure relief opening 27, and the pressure relief diaphragm has at least one indentation formed therein. When the interior of the containing cavity reaches a second preset pressure, the pressure relief diaphragm is broken along the indentation, and the fire extinguishing agent 43 in the containing cavity is sprayed outwards through the broken pressure relief diaphragm. Preferably, a plurality of indentations are formed on the pressure relief membrane, and the indentations are radially arranged in a radial state.

When the pressure in the containing cavity reaches a second preset pressure, the aluminum film is broken under the action of the pressure, and the fire extinguishing agent 43 in the containing cavity is sprayed outwards through the broken part of the aluminum film. It is understood that the magnitude of the second preset pressure may be adjusted by providing aluminum films of different thicknesses.
In another embodiment, the pressure relief member is a pressure relief valve mounted to the pressure relief port 27. When the pressure in the accommodating cavity is smaller than the second preset pressure, the pressure relief valve is in a cut-off state. When the containing cavity reaches a second preset pressure, the pressure relief valve is switched to a conduction state under the action of the pressure, and the fire extinguishing agent 43 in the containing cavity is sprayed outwards through the conducted pressure relief valve.
The fire extinguishing module 40 further comprises a packaging bag 41 made of combustible materials, the packaging bag 41 is provided with at least one containing cavity, the fire extinguishing agent 43 is packaged in the containing cavity, and the packaging bag 41 plays a role in packaging and fixing the fire extinguishing agent 43 and prevents the fire extinguishing agent 43 from accumulating towards the bottom of the main shell 20 under the action of gravity.
Specifically, in one embodiment, the packaging bag 41 has a plurality of receiving chambers that are interconnected by a plurality of channels, each receiving chamber and channel having a fire suppressant 43 packaged therein. Like this, fire extinguishing agent 43 is injectd in a plurality of holding chambeies of encapsulation bag 41, consequently can not pile up the extrusion to main casing body 20's bottom under the action of gravity to guarantee that fire extinguishing agent 43 has sufficient contact surface area with the air, thereby contact and abundant burning with the air easily when fire extinguishing device 100 starts, make fire extinguishing device 100 reach better burning speed, injection pressure and the initial velocity of spraying, and then reach good fire suppression effect.
Specifically, in another embodiment, the packaging bag 41 has only one accommodating cavity, and the fire extinguishing agent 43 is filled in the accommodating cavity and then the air in the accommodating cavity is drawn out, so as to achieve the purpose of preventing the fire extinguishing agent 43 from accumulating toward the bottom of the main housing 20 under the action of gravity.
The fire extinguishing agent 43 includes an aerosol in any combination of one or more of powder, granule, tablet or block, and the powder or fragments of the aerosol are ignited to generate inert gas and metal particles, thereby performing the fire extinguishing function. Compare aerosol among the prior art, aerosol in this application can react quicker when starting, produces great impact force and has better fire control effect.
Specifically, the aerosol in the prior art is usually compacted into a column shape by a powdered aerosol, so that the combustion speed can be controlled by combusting one surface of the compacted aerosol, thereby achieving the effect of stable spraying. Because the combustion process of the compacted aerosol is combustion layer by layer, the combustion area in unit time is limited, so that the inert gas and metal particles generated by the combustion of the aerosol are gradually released, and the released inert gas in unit time is less, the fire extinguishing speed is slower, and the fire extinguishing effect is poorer. In the application, the aerosol is not pressed, but is directly stacked in the packaging bag in a powder, particle, sheet or block form, and the unpressed aerosol is quickly and completely detonated once ignited to release a large amount of inert gas instantly, so that the oxygen concentration in the space in unit time can be greatly reduced, and the fire extinguishing device has higher fire extinguishing speed and better fire extinguishing effect.
In some embodiments, the fire extinguishing assembly 40 further comprises a heat-sensitive wire 45, one end of the heat-sensitive wire 45 is enclosed in the containing cavity of the packaging bag 41 and is in contact with the fire extinguishing agent 43, and the other end of the heat-sensitive wire 45 extends out of the containing cavity of the packaging bag 41. When a fire occurs outside the sealing bag 41 and the temperature rises, the heat-sensitive wire 45 is spontaneously ignited and the fire extinguishing agent 43 in contact with the heat-sensitive wire 45 is ignited to explode the fire extinguishing agent 43, and the fire extinguishing agent 43 is further sprayed out of the main housing 20 to realize a fire extinguishing function.
The fire extinguishing device 100 and the electrical appliance module with the same have the advantages that the fire extinguishing device 100 is of a flat structure, so that the fire extinguishing device occupies a small space, can be placed in a narrow space, and can be widely applied to different occasions. Moreover, the fire extinguishing agent 43 of the fire extinguishing device 100 comprises uncompacted aerosol which, once ignited, rapidly detonates all together, thus having a higher fire extinguishing rate and a better fire extinguishing effect.
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.
