Support legs 2 are fixedly connected to the four corner parts of the lower part of the test chamber 1 respectively; a sealing door 3 is installed on the front part of the test chamber 1 through hinges, and an observation window 4 is fixedly connected to the opening at the middle part inside the sealing door 3; a smoke collecting pipe 5 is fixedly connected to the opening at the middle part of the upper part of the test chamber 1, and a suction valve 6 is fixedly connected to the upper opening of the smoke collecting pipe 5; an air purifier 7 is separately arranged at the rear part of the test chamber 1, and the input end of the air purifier 7 is connected to the upper end of the suction valve 6 through a pipeline; an intake valve 8 is fixedly connected to the opening at the middle part of the left part of the test chamber 1, and an installation hopper 9 is fixedly connected to the left end of the intake valve 8, wherein a fan 10 is fixedly connected to the left side inside the installation hopper 9; after the air purifier 7 is turned on, it can suck and purify the smoke in the test chamber 1 through the pipeline, the suction valve 6 and the smoke collecting pipe 5, avoiding the problem of the smoke generated by the battery polluting the environment; when the fan 10 is started, the fan 10 can input air into the test chamber 1 through the intake valve 8, thereby avoiding the problem that negative pressure is generated in the test chamber 1 and affecting the combustion of the battery.

[0014] One of the new energy battery combustion test chambers further includes a gas surrounding fire extinguishing component 11, and the gas surrounding fire extinguishing component 11 is fixedly connected to the inner bottom of the test chamber 1, which is beneficial to achieving the effect of facilitating the extinguishing of the battery, thereby avoiding the problem of safety accidents in case of emergencies, and can effectively improve the use safety of the test chamber.

[0015] In this implementation scheme, in combination with the attached Figure 3 As shown, the gas surrounding fire extinguishing component 11 includes a hollow box 111. A recessed portion 112 is provided on the upper middle side of the hollow box 111, and exhaust holes 113 are respectively opened at the four peripheral parts on the upper side of the inner wall of the recessed portion 112; a gas inlet pipe 114 is fixedly connected to the right opening of the hollow box 111, and a valve 115 is fixedly connected to the right end of the gas inlet pipe 114. A carbon dioxide tank 116 is connected to the right end pipeline of the valve 115.

[0016] In this implementation scheme, specifically, the lower part of the hollow box 111 is fixedly connected to the inner bottom of the test chamber 1.

[0017] In this implementation scheme, specifically, the right end of the gas inlet pipe 114 penetrates through the lower right side inside the test chamber 1.

[0018] In this implementation scheme, specifically, the carbon dioxide tank 116 is separately arranged outside the test chamber 1.
