In addition, regarding the structural form of the split screw 4, there are the following two embodiments:
example 1: the opposite-pulling screw 4 comprises a T-shaped screw 4.1 and a screw sleeve 4.2, the T-shaped screw 4.1 is penetrated at the top of the upper cover 1, the bottom of the lower cover 2 is fixedly connected with the screw sleeve 4.2, and the T-shaped screw 4.1 is in threaded fit with the screw sleeve 4.2. In this embodiment, the screw sleeve 4.2 is vertically fixed at the bottom of the lower cover 2, and at this time, the upper cover 1 and the lower cover 2 can be locked by pulling the T-shaped screw 4.1 penetrating the upper cover 1 into the screw sleeve 4.2, so that abnormal release such as deformation of a cavity, swelling of a housing, separation of a housing of the device is not easy to occur.
Example 2: the opposite-pulling screw 4 comprises a T-shaped screw 4.1 and a screw sleeve 4.2 with a T-shaped structure, the T-shaped screw 4.1 is penetrated at the top of the upper cover 1, the screw sleeve 4.2 is penetrated at the bottom of the lower cover 2, and the T-shaped screw 4.1 is in threaded fit with the screw sleeve 4.2.

Preferably, the aerosol generating means is in contact with the initiation line of the initiating component on one side. In the actual use process, the aerosol generating agent can be triggered to burn through the starting component, so that aerosol fire extinguishing substances are generated and sprayed to perform the fire extinguishing process.
Preferably, the aerosol generating agent is an aerosol generating agent powder or a crumb. The aerosol generating agent powder or fragments are ignited to generate inert gas and metal particles, the aerosol generating agent on the market is compacted to be made into a grain shape, the combustion speed of the grain is controlled by burning one side of the grain, so that the effect of stable spraying is achieved, the combustion process is layer by layer, the aerosol generating agent is fully combusted because the combustion area of the grain is limited, part of inert gas and metal particles are released, the metal particles rob free radicals to block the chained combustion reaction to extinguish fire, and the inert gas achieves the auxiliary fire extinguishing effect; the aerosol generating agent powder or fragments of the patent are not pressed into a grain shape, but are directly stacked in a hollow cavity formed by the upper cover 1 and the lower cover 2, and once the aerosol generating agent powder or fragments are ignited, all the powder or fragments directly deflagrate, so that a large amount of inert gas is instantaneously released, the oxygen concentration in a space in unit time is reduced, and a better fire extinguishing effect is achieved.

Preferably, the starting component is a thermosensitive wire structure or an electric ignition head structure. In this embodiment, when the starting member is an electric ignition head structure, it is connected to a fire detection device (the fire detection device is a temperature sensor and/or a smoke sensor). When fire, overheat and other conditions occur, the fire detection device detects the high temperature environment generated by the fire, and then sends a signal to the microprocessor, and the microprocessor controls the starting component to ignite the aerosol generating agent. When the starting component is of a thermosensitive wire structure, the thermosensitive wire structure is simpler, so that the thermosensitive wire can be automatically started when a fire disaster occurs, and the thermosensitive wire directly ignites aerosol generating agent without being matched with an additional fire disaster detection device and other external equipment.
Preferably, a plurality of spraying holes 3 are formed on the side part of the upper cover 1 and the side part of the lower cover 2 corresponding to the hollow cavity.
The working process of the embodiment is as follows:

step 1): when the batteries in the lithium battery box are in fire, the starting component ignites the aerosol generating agent;
step 2): the aerosol generating agent is ignited, and fire extinguishing substances are generated, the fire extinguishing substances are sprayed out from the spraying holes 3, then the whole lithium battery box is filled, the combustion chain is blocked, and the fire extinguishing process is carried out; in the above process, the aerosol generating agent detonates when ignited and generates a shock wave containing inert gas, isolating the combustible vapor and/or gas from the flame and carrying away heat in the fire scene.
In the fire extinguishing process, the upper cover 1 and the lower cover 2 are locked together by the opposite-pulling screw 4, so that abnormal release such as chamber deformation, housing bulge and device housing separation is not easy to occur. Through practical tests, before the fire extinguishing process occurs, the thickness of the device is 16.36mm, after the fire extinguishing process occurs, the thickness of the device is 16.72mm, the deformation amount of the device is very small, and the device has good deformation prevention effect on the pull screw 4.
