Detailed Description

The following further description is made with reference to the drawings and specific embodiments.

As shown in fig. 1 to 3, the present embodiment provides an unpressurized perfluorohexanone fire extinguishing apparatus 100, which mainly comprises a flat box-shaped body 10 and a fire extinguishing assembly 20, wherein the body 10 is provided with a cavity 11 with an upward opening and a sealing cover 12 for sealing the cavity 11. Wherein, fire extinguishing assembly 20 includes perfluor hexanone ketone package 21, aerosol gas production grain 22 and trigger device 23, and this trigger device 23 sets up in the bottom of body 10, and aerosol gas production grain 22 is close to trigger device 23 and sets up and forms heat conduction formula with trigger device 23 and be connected. The heat conduction type connection comprises direct contact or indirect contact through a heat conduction component, so that the aim of smooth heat conduction is fulfilled. The trigger device 23 is connected with the outside through an electric wire or a heat-sensitive wire, when a fire disaster occurs, the trigger device 23 is triggered to generate high temperature, then the heat is conducted to the aerosol gas generating drug column 22 to ignite the aerosol gas generating drug column 22, the aerosol gas generating drug column 22 burns to generate a large amount of aerosol, meanwhile, the heat generated by burning burns or melts the packaging bag of the perfluorohexanone material bag 21, the perfluorohexanone inside is rapidly vaporized under the pressure of the high-temperature aerosol and is sprayed out of the body 10, and the flame in the fire disaster area is extinguished, so that the fire extinguishing effect is achieved.

Specifically, as shown in fig. 4, the body 10 is provided with two fixing locations 13 at the lower part of the cavity 11, and each fixing location 13 is provided with an aerosol gas generating drug column 22, so that the left lower part and the right lower part of the perfluorohexanone material bag 21 can be heated simultaneously, the destruction time of the perfluorohexanone material bag 21 is shortened, and the fire extinguishing speed is increased. In order to improve the efficiency of heat conduction, the aerosol gas generating grain 22 is closely attached to the inner wall of the body 10, so that the heat generated by the trigger device 23 can be quickly and efficiently conducted to the aerosol gas generating grain 22, thereby quickly reaching the ignition point of the aerosol gas generating grain 22 and further shortening the response time of the product.

In this embodiment, the bottom of the body 10 is provided with a triggering hole 14 parallel or substantially parallel to the bottom of the body 10, a thin wall 15 is reserved between the triggering hole 14 and the aerosol gas generating charge 22, and a triggering device 23 is fixed in the triggering hole 14, and the generated heat is suitable for being conducted to the aerosol gas generating charge 22 through the thin wall 15 to ignite the aerosol gas generating charge 22. In order to increase the heat conduction effect, the thin wall 15 is made of heat conductive material, i.e. the body 10 should be made of metal heat conductive material such as iron, copper, etc.

Referring to fig. 5, in order to prevent the perfluorohexanone inside the perfluorohexanone pack 21 from leaking to the aerosol gas generating column 22 when the packaging bag of the perfluorohexanone pack 21 is damaged and thus submerging the aerosol gas generating column 22, in this embodiment, an isolation pad 24 is further disposed between the perfluorohexanone pack 21 and the aerosol gas generating column 22, and a plurality of air vents 241 are disposed on the isolation pad 24. The width of the isolation pad 24 is matched with the width of the cavity 11, so that the perfluorohexanone is prevented from flowing into the aerosol gas-generating charge column 22 through a gap between the isolation pad 24 and the inner wall of the body 10 to influence the normal combustion of the aerosol gas-generating charge column 22. The isolation pad 24 is used for preventing the perfluorohexanone from flowing back to the aerosol gas generating column 22 on one hand, and on the other hand, high-temperature aerosol generated by the combustion of the aerosol gas generating column 22 can be shot to the perfluorohexanone material bag 21 at a high speed through the plurality of air holes 241, so that the perfluorohexanone material bag 21 is quickly damaged in a short time, and the air pressure in the cavity 11 is rapidly increased due to the large generation of the aerosol, so that the perfluorohexanone can be quickly sprayed out efficiently, and the quick fire extinguishing is realized. The aerosol also adopts a substance with a fire extinguishing function, and the fire extinguishing effect is better after the aerosol and vaporized perfluorohexanone are sprayed together.

The sealing cover 12 of the present embodiment is fixedly connected to the body 10 by two or more first screws 30, and a sealing rubber ring 40 is further disposed between the sealing cover 12 and the body 10 to ensure that the perfluorohexanone does not leak out from between the sealing cover 12 and the body 10 when fire is extinguished, in order to enhance the sealing effect.

The body 10 of this embodiment is configured in a rectangular parallelepiped or flat box-like structure, and in order to increase the burst rate of perfluorohexanone, the present embodiment is provided with a plurality of nozzles 16 on at least one side surface thereof, and the nozzles 16 have a diameter of 3-6mm, thereby forming an unobstructed air passage. The number of the nozzles 16 is not excessive, which affects the speed and pressure of the perfluorohexanone spray and thus the fire extinguishing effect, and the specific number can be set according to the size of the body 10.

In addition, the packaging bag of the perfluorohexanone pack 21 of this embodiment is a film bag made of PP or PE material. The product has stable performance, can be stored for a long time, and can be quickly broken at high temperature, so that the perfluorohexanone in the product is smoothly discharged, and the fire extinguishing performance of the product is ensured.

Referring to fig. 1 again, the present embodiment further includes a housing fixing member 50 for being installed in a fire extinguishing place, the housing fixing member 50 is a frame structure, and the body 10 can be fixed in the housing fixing member 50 by two or more second screws 60 after being plugged into the housing fixing member 50. Meanwhile, the shell fixing piece 50 is provided with a plurality of mounting holes 51, so that the non-pressure-storage perfluorohexanone fire extinguishing device 100 can be mounted in a required place to protect the place from fire.

In summary, the body is provided with the cavity, the perfluorohexanone material bag and the aerosol gas generating column are arranged in the cavity, the aerosol gas generating column is heated by the trigger device until ignition occurs, the aerosol gas generating column is combusted to generate a large amount of aerosol and heat, and the packaging bag of the perfluorohexanone material bag is damaged by the heat, so that the perfluorohexanone inside is sprayed out of the body under the pressure of the aerosol. Therefore, the invention has simple structure, and the size can be flexibly set according to the size of the body, thereby realizing the development of products towards miniaturization and microminiaturization, and enabling the products to be suitable for more different occasions. Moreover, the product can be designed into a flat shape, is suitable for being installed in a narrow space, and further expands the application scene of the product. Meanwhile, as the aerosol gas generating grain can rapidly generate a large amount of aerosol when burning, perfluorohexanone can be rapidly sprayed out, thereby improving the fire extinguishing effect.
