[0039] See attached Figures 1 to 10 As shown, the utility model provides a technical solution: a hot aerosol fire extinguishing device, comprising a fire extinguishing body 10 and an upper cover 20, the upper cover 20 is arranged on the fire extinguishing body 10, and the upper cover 20 has a spray unit; the spray unit includes a plurality of first nozzles 21 distributed in an array, or the spray unit includes a second nozzle 22, four third nozzles 23 and four nozzle groups, the four third nozzles 23 and the four nozzle groups are arranged at intervals around the second nozzle 22, and there is a nozzle group between every two adjacent third nozzles 23, and the nozzle group is composed of a plurality of fourth nozzles 24.

[0040] Exemplarily, the overall shape of the fire extinguishing body 10 may be rectangular or circular.

[0041] A first embodiment of the spray unit: when the overall shape of the fire extinguishing body 10 is rectangular, the plurality of first spray ports 21 are distributed in a rectangular array.

[0042] A second embodiment of the spray unit: when the overall shape of the fire extinguishing body 10 is circular, the plurality of first spray ports 21 are distributed in a circular array.

[0043] When the charge is in uniform combustion, the charge is in an orderly combustion process, and its gas production per unit time is certain. At this time, if the first nozzle 21 is too small, the internal gas cannot be discharged, resulting in explosion due to cavity pressure or too rapid spraying leading to flames. Therefore, in this embodiment, the radius of the first nozzle 21 is preferably 4mm, and the radius of the combustion surface of the charge is preferably 32mm. In this way, the spraying can be uniform without rapid spraying, blockage or pressure holding, achieving the effect of uniform spraying.

[0044] A third embodiment of the spray unit: when the overall shape of the fire extinguishing body 10 is a rectangle, the four third nozzles 23 and the four nozzle groups are distributed in a circular array with the axis of the second nozzle 22 as the axis.

[0045] In this way, distribution and diffusion can be achieved so that the entire spraying surface can produce gas. When the gas acts on the fire extinguishing body 10, the airflow inside the cavity of the fire extinguishing body 10 is sprayed out as a whole, and the chemical coolant 122 is fully decomposed to increase the spraying amount.

[0046] See attached Figures 5 to 8 As shown, in some embodiments, the fire extinguishing body 10 includes a cylinder 11 and a cooling component 12, the cooling component 12 is arranged in the cylinder 11, the cooling component 12 includes a plurality of first bearing parts 121 and a plurality of first cooling units, the first bearing parts 121 and the first cooling units are alternately arranged in sequence along the vertical direction, wherein the first cooling unit is composed of a plurality of chemical coolants 122 distributed in an array.

[0047] Exemplarily, the cylinder 11 may be a hollow structure with an opening at the top; the cylinder 11 may also be composed of a shell 111 and a lower cover 112, and the lower cover 112 is detachably connected to the shell 111. The first bearing portion 121 is a mesh structure. The chemical coolant 122 may be a columnar solid formed by pressing one or more combinations of potassium nitrate, potassium hydrogen tartrate, and ferrocene.

[0048] According to this embodiment, the first bearing portion 121 can not only support the first cooling unit, but also reserve a buffer space for the first cooling unit to prevent the heat inside the cylinder 11 from causing a sudden increase in local pressure. When the aerosol passes through the first cooling unit, the first cooling unit cools the aerosol, one is to prevent the temperature inside the cylinder 11 from rising suddenly, and the other is to prevent the high-temperature aerosol from aggravating the expansion of the fire. In addition, the aerosol is gradually cooled by multiple first cooling units, so that a better cooling effect can be achieved.

[0049] See attached Figures 5 to 8As shown, in some embodiments, the fire extinguishing body 10 includes a second cooling unit, which is disposed above the cooling component 12, and the second cooling unit is composed of a plurality of first physical cooling balls distributed in an array.

[0050] Exemplarily, the first physical cooling ball can be one or more combinations of ceramic balls and goose warming stones.

[0051] According to this embodiment, the second cooling unit can further cool the aerosol and buffer the impact force of the aerosol to prevent the high-temperature molten chemical coolant 122 residue from being carried by the aerosol to each nozzle and clogging each nozzle.

[0052] See attached Figure 5 As shown, in some embodiments, the fire extinguishing body 10 includes a silicone sleeve 15, and the silicone sleeve 15 is sleeved on the cooling component 12 and the second cooling unit.

[0055] Exemplarily, the structure of the second bearing portion 14 may be the same as that of the first bearing portion 121 .

[0056] According to this embodiment, the second bearing portion 14 can reserve a buffer space for the second cooling unit and the upper cover 20 to prevent the first physical cooling ball from being impacted by the aerosol and clogging the nozzles.

[0057] See attached Figure 5 and 9 As shown, in some embodiments, the fire extinguishing body 10 includes a support plate 16, which is disposed below the cooling assembly 12, and the support plate 16 is used to carry the explosive column.

[0059] Exemplarily, the second physical cooling ball can be a ceramic ball, a goose warming stone, or a combination thereof.

[0060] According to this embodiment, the heat insulation plate 17 isolates the high temperature of the drug column area, reduces the heat transfer to the area between the support plate 16 and the bottom of the barrel 11 or the lower cover 112, thereby preventing the wiring harness in this area from being damaged due to high temperature. During this period, the second physical cooling ball can absorb heat, thereby playing a role in cooling.

[0061] In some embodiments, the support plate 16 and / or the heat insulation plate 17 are made of a heat insulation material. Optionally, the heat insulation material may be glass fiber or a vacuum plate.

[0062] According to this embodiment, when the support plate 16 is made of a heat-insulating material, the support plate 16 can first isolate a large amount of temperature. When the heat-insulating plate 17 is made of a heat-insulating material, the heat-insulating plate 17 can enhance the effect of isolating heat.

[0063] See attached Figure 1 and 5 As shown in Figures 5 to 6 , in some embodiments, a sticker 25 is included, and the sticker 25 is pasted on the upper cover 20 .

[0064] According to this embodiment, the sticker 25 can play a dust-proof and moisture-proof effect. First, it can prevent dust particles from clogging the nozzles. Second, it can prevent dust particles from entering the barrel 11, causing the drug column to be difficult to ignite or the first cooling unit and the second cooling unit to fail. Alternatively, it can prevent the first cooling unit, the second cooling unit or moisture from causing the drug column to be difficult to ignite or the first cooling unit and the second cooling unit to fail.

[0065] See attached Figure 6 As shown, in some embodiments, a rubber ring 30 is included, and the rubber ring 30 is arranged between the fire extinguishing body 10 and the upper cover 20.

[0066] Exemplarily, a rubber ring 30 may also be disposed between the cylinder 11 and the lower cover 112 .

[0067] According to this embodiment, the rubber ring 30 can strengthen the sealing effect between the cylinder 11 and the upper cover 20 or the lower cover 112, so as to achieve better dustproof and moisture-proof effects.

[0068] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
