[0001] This utility model relates to the field of fire extinguishing equipment technology, specifically to an aviation safety box for handling thermal runaway of lithium batteries. Background Technology

[0002] In recent years, with the widespread use of portable electronic devices and the surge in lithium battery air transport, fires and smoke incidents caused by lithium batteries have frequently occurred in the global aviation sector, posing a serious threat to aviation safety. The core risk of such incidents stems from the thermal runaway chain reaction of lithium batteries: mechanical compression, short circuits, or high temperatures may trigger electrolyte decomposition, releasing toxic gases and large amounts of heat, which can rapidly lead to explosions or fires in the confined cabin environment.

[0003] However, existing aviation emergency response methods have significant limitations. Lithium battery combustion causes serious safety damage to the cabin interior. Not only can the fire easily spread inside the cabin, but the toxic gases produced by the combustion can also harm human health and the environment. Utility Model Content

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] like Figure 1 and Figure 2 As shown, this utility model discloses an aviation safety box for handling thermal runaway of lithium batteries. It is rectangular and includes an open box body 1 and a box cover 2. One side of the opening of the box cover 2 is hinged to the other side of the opening of the box body 1. Two matching latches 5 are respectively provided on the other side of the box cover 2 and the box body 1 opposite to the hinged side. A handle 6 is provided on the box body 1 between the two latches 5.

[0030] The opening edge of the lid 2 is provided with a high-temperature resistant sealing ring that matches the opening edge of the box body 1. After the lid 2 is closed on the box body 1 and the latch 5 is locked, the sealing ring fills the gap between the lid 2 and the box body 1, thus sealing the inside of the protective box.

[0031] The bottom of the case 1 and the top of the case lid 2 are respectively provided with two long strip-shaped protrusions 13. The protrusions 13 are provided with nylon hook and loop fasteners. The corresponding hook and loop fasteners are provided in the aircraft cabin or in the environment where the protective case is placed to secure the protective case. In addition, the corresponding hook and loop fasteners can also be provided on the packaging that contains other emergency items so that other emergency items can be fixedly placed on the protective case.

[0032] The cover 2 and the side of the box body 1 where the latch 5 is located are respectively provided with corresponding through holes 3. After the cover 2 and the box body 1 are closed, the through hole 3 is provided with a lead seal 4, which serves as an anti-tampering mark to confirm that the protective box has not been opened without authorization.

[0033] The top of the cover 2 is equipped with a water inlet assembly, an observation window assembly, and a filter assembly. After the thermal runaway lithium battery and other flammable items are placed in the box 1, fire extinguishing agent, such as water or other inert liquid, is injected into the box 1 through the water inlet assembly to quickly reduce the temperature of the lithium battery or suppress the thermal runaway fire. The observation window assembly is used to view the internal condition of the box 1, and the filter assembly is used to release the internal pressure or gas of the box 1.

[0034] The water inlet assembly includes a water inlet 7 located on the top of the tank cover 2, and a screw cap 8 is internally threaded onto the water inlet 7. By opening the screw cap 8, liquid can be injected into the tank 1 through the water inlet 7, and by tightening the screw cap 8, the water inlet 7 can be closed.

[0035] The observation window assembly includes an observation opening 9 located at the top of the lid 2, with a transparent observation window 10 inside the observation opening 9. Through the observation window 10, the fire situation inside the container 1 can be observed, preventing serious consequences from being caused by opening the lid 2 if the fire is not under control. The observation opening 9 is located at the center of the top of the lid 2 to provide the maximum viewing angle for the situation inside the container 1.

[0036] The filter assembly includes an exhaust trough located on the top of the cover 2. The exhaust trough includes multiple evenly arranged circular or strip-shaped air holes. A filter trough is located on top of the exhaust trough, and a filter box 11 is located inside the filter trough. A baffle 12, detachably connected to the filter trough, is located on the top of the filter box 11. Multiple strip-shaped air outlet slots are evenly arranged on the baffle 12. A protective film (not shown in the figure) is provided on the top surface of the baffle 12. Before the protective box is put into use, the protective film can prevent impurities and water from entering the filter box 11.

[0037] In the event of thermal runaway of a lithium battery, it can be placed inside the enclosure 1 to prevent the lithium battery from igniting and causing a fire. The water inlet assembly can inject fire extinguishing agent (such as water or other inert liquids) into the enclosure to quickly reduce the temperature of the lithium battery or suppress the fire caused by thermal runaway. The filter assembly can release the pressure inside the enclosure and filter the toxic gases released during thermal runaway in emergency situations (such as thermal runaway of lithium batteries), preventing external environmental pollution and personnel poisoning. The observation window assembly can be used to observe the internal situation and prevent secondary injuries caused by opening the enclosure 1 if the fire is not under control or extinguished.

[0038] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the technical solutions of this utility model. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of this utility model patent.
