[0034] A layer of sodium bicarbonate solid powder is laid at the bottom of the inner box body 3, and the amount of sodium bicarbonate is determined according to the volume of carbon dioxide generated when the sodium bicarbonate is completely decomposed at room temperature, which is 1.0-2.5 times the volume of the inner box body 3.

[0040] When the total weight of the box and the inner object does not exceed 5 kg, the length of the four selected springs 4 changes by no more than 5% compared to the case where the device is placed still and not affected by external forces
[0041] As an optional embodiment, the outer side of the top opening of the inner box 3 is coaxially fixed with an outward flange 6, and the inner side of the bottom opening of the outer box 2 is fixed with an inward flange 7. The outward flange 6 and the inward flange 7 are limited and matched.
[0042] The four edges of the open end of the inner box 3 are designed as outward flanges 6. The four edges of the open end of the outer box 2 are designed as inward flanges 7. The design of the flanges can meet the needs of the upward and downward movement of the outer box 2 and limit the outer box 2 from being separated from the inner box 3.
[0043] The four edges of the open end of the inner box 3 are designed as outward flanges 6 with a width of 0.5-1 cm and a thickness of 0.5-1 cm. The four edges of the open end of the outer box 2 are designed as inward flanges 7 with a width of 0.1 cm less than the outward flange 6 and a thickness consistent with the inner box 3. Under normal circumstances, the inward flange 7 of the outer box 2 can block the escape of gas in the inner box 3.
[0044] When the bottom of the outer box 2 coincides with the open side of the inner box 3, that is, the outer box 2 maximally inverts and closes the inner box 3, the distance between the inward flange 7 and the bottom of the inner box is 2-5 cm.
[0045] As an optional embodiment, the top of the outer box 2 is provided with an opening, one end of a top cover 8 is hinged at the top opening of the outer box 2, and the other end of the top cover 8 is connected to the side wall of the outer box 2 through a lock buckle 5.
[0046] As an optional embodiment, a handle 1 is provided at the top of the top cover 8.
[0047] The top surface of the outer box 2 is transformed into an upwardly movable top cover 8, one side of the top cover 8 is hinged to the outer box 2, and the other side is installed with a lock buckle 5 at an intermediate position. The top cover 8 and the opening of the inner box 3 can be smoothly closed, and when the top cover 8 is buckled, the opening of the inner box 3 can be completely closed. The top cover 8 is equipped with a pullable handle 1, which is convenient for carrying the device.
[0048] As an optional embodiment, the materials of the outer box 2 and the inner box 3 are metal materials with a tensile strength exceeding 350 MPa.
[0049] As an optional embodiment, the wall thickness of the outer box 2 and the inner box 3 is 1-3 mm.
[0050] The material of the inner box 3 and the outer box 2 is titanium alloy material or stainless steel material or other material with tensile strength of more than 350 MPa or equivalent tensile strength without combustion, the wall thickness of the inner box 3 and the outer box 2 is 1-3 mm, and the thickness of the top cover is 2-3 mm, so as to meet the explosion resistance requirement of the notebook computer, tablet computer, power bank and other portable electronic devices.
[0051] The working principle of the device is that the top cover 8 is opened, the portable electronic device with spontaneous combustion or spontaneous combustion tendency is placed in the inner box 3, and the top cover 8 is quickly closed and buckled. After the sodium bicarbonate powder laid at the bottom of the device is heated, it begins to decompose and release carbon dioxide. When the temperature is higher than 50 DEG C, sodium bicarbonate begins to decompose under heat, when the temperature is higher than 65 DEG C, the decomposition of sodium bicarbonate accelerates, when the temperature is higher than 270 DEG C, sodium bicarbonate completely decomposes, and the amount of carbon dioxide generated by the complete decomposition of 250 grams of sodium bicarbonate is nearly 66.7 liters (the gas volume at room temperature, the volume is larger at high temperature), which is more than 2.0 times (about 2.1 times) the maximum volume of the inner box 3. Even if 20% decomposition occurs at 50 DEG C, the amount of carbon dioxide covering a notebook computer or a power bank in the box can meet the requirement. The density of carbon dioxide is greater than that of air and oxygen, and the carbon dioxide generated by the decomposition of sodium bicarbonate rapidly reduces the oxygen concentration in the box, thereby preventing the electronic device from further burning. When the spontaneous combustion electronic device is enclosed in the inner box 3, due to its high temperature, the inner gas will be heated and expanded, and the gas pressure in the box will increase. At this time, the outer box 2 nested on the inner box 3 will move upward in the height direction (longitudinal direction), and under the action of the weight of the outer box 2 and the spring 4, finally, the pressure in the box and the external force reach balance. In the extreme case, the outer box moves upward greatly, but due to the pulling of the spring 4 and the balance between the outer edge 6 of the inner box 3 and the inner edge 7 of the outer box 2, the outer box 2 can be prevented from flying out of the inner box.
[0052] The working process of the device is as follows:
[0053] Open the top cover, put the portable electronic device which is self-igniting or has self-igniting tendency into the inner box, close and fasten the top cover quickly. The sodium bicarbonate powder laid at the bottom of the device starts to decompose and release carbon dioxide when heated. When the temperature exceeds 50℃, sodium bicarbonate starts to decompose. When the temperature exceeds 65℃, the decomposition of sodium bicarbonate accelerates. When the temperature exceeds 270℃, sodium bicarbonate decomposes completely. 250g of sodium bicarbonate decomposes completely to produce nearly 66.7 liters of carbon dioxide (the volume of gas at room temperature, the volume is larger at high temperature), which is more than 2.0 times (about 2.1 times) the maximum volume of the inner box. Even if 20% decomposition occurs at 50℃, it can meet the needs of carbon dioxide for covering a notebook computer or a power bank in the box. The density of carbon dioxide is greater than that of air and oxygen, and the carbon dioxide produced by the decomposition of sodium bicarbonate quickly reduces the oxygen concentration in the box, thereby preventing the electronic device from further burning. When the self-igniting electronic device is enclosed in the inner box, due to its high temperature, it will cause the inner gas to expand when heated, and the gas pressure in the box will increase. At this time, the outer box nested on the inner box will move upward in the height direction (longitudinal direction). Under the action of the weight of the outer box and the spring, finally, the pressure in the box and the external force reach a balance. In extreme cases, the outer box will move upward greatly, but due to the pulling of the spring and the balance between the outer edge of the inner box and the inner edge of the outer box, the outer box can be prevented from flying out of the inner box.
[0054] The outer box 2 can cover the inner box 3. The outer box 2 and the inner box 3 are the main components of the entire box composed of the inner and outer nested boxes. Each of the four corners of the opening of the outer box 2 and the bottom of the inner box 3 is provided with a ring buckle 9. The extendable spring 4 is installed on the ring buckle 9 to connect the inner box 3 and the outer box 2. The four outward edges 6 of the opening end of the inner box 3 are opposite to the four inward edges 7 of the opening end of the outer box 2. The edges can meet the needs of the upward and downward movement of the outer box and can limit the outer box from separating from the inner box. The top of the outer box 2 is provided with a movable top cover 8. The top cover 8 is provided with a lock buckle 5 and a handle 1 for lifting. The lock buckle 5 can ensure the sealing of the box, and the handle 1 can be used to lift and move the entire box. In order to strengthen the fire extinguishing effect, a layer of sodium bicarbonate solid powder can be laid at the bottom of the inner box.
[0055] When the device is in operation, first place the device in a suitable processing area, open the top cover upward, and then put the electronic device to be processed. After placing, fasten the top cover, and seal the entire device through the lock buckle. When the electronic device generates heat, the bottom layer of sodium bicarbonate can decompose into carbon dioxide and water, and the carbon dioxide can dilute the oxygen in the air. When the internal gas pressure is too large, the outer box will move upward. Due to the restriction of the protruding edges of the spring, the outer box will not separate from the entire device.

The inner box 3 is 50 cm long, 35 cm wide and 18 cm high, the bottom is paved with 250 grams of solid sodium bicarbonate powder, the outer edge of the open end of the inner box 3 is provided with a 1.0 cm wide and 1 cm thick outward edge 6, and the inner edge of the open end of the outer box 2 is provided with a 0.9 cm wide and 1 cm thick inward edge 7.
