[0002] Lithium batteries can deform, expand, and leak electrolyte under high temperatures. After the lithium battery production is completed, it is necessary to sample and test the lithium batteries under simulated high temperature conditions to determine their heat resistance.
[0003] A lithium battery heat resistance testing device disclosed in Chinese Patent Application Publication CN220207489U includes a housing, a control panel, a lifting placement device, a liquid collection device, a lithium battery, a heating wire, and a fire extinguishing device.

[0004] The above technical solution enables liquid collection when lithium batteries leak, and facilitates the handling of lithium battery heat resistance testing equipment. However, when using this device, the battery releases highly toxic gases such as carbon monoxide and hydrogen fluoride at high temperatures, and the device lacks gas purification capabilities. As a result, after the test is completed, the toxic gases are directly emitted into the outside environment, which may have a certain impact on the surrounding environment and the health of people, thereby reducing the practicality of the device.
[0005] Therefore, a heat resistance testing device for batteries is proposed here. Utility Model Content

A locking block 5 and a locking frame 6 are fixedly installed on the front of the chassis 1. The locking block 5 is engaged inside the locking frame 6. The installation of the locking block 5 and the locking frame 6 plays a role in locking the chassis 1, thereby preventing the chassis 1 from opening on its own and ensuring the stability of the chassis 1.
[0029] Please refer to this carefully. Figure 1 and Figure 2 An air pump 203 is fixedly installed on the left side of the casing 1. The air outlet of the air pump 203 extends into the interior of the casing 1. An activated carbon plate 204 is snapped into the interior of the processing tank 201. A storage tank 205 and a water pump 206 are fixedly installed on the right side of the processing tank 201. The water inlet of the water pump 206 extends into the interior of the storage tank 205. The water outlet of the water pump 206 is fixedly connected to a conveying pipe 207.

A sewage pipe 7 is fixedly connected to the back of the processing tank 201. A valve 8 is fixedly connected to the outer surface of the sewage pipe 7. The installation of the sewage pipe 7 and the valve 8 allows the chemical agents after the reaction to be discharged through the sewage pipe 7.
[0030] Please refer to this carefully. Figure 2 , Figure 3 and Figure 4A connecting frame 208 is fixedly installed on the inner wall of the treatment tank 201. A connecting pipe 209 is fixedly installed on the bottom surface of the connecting frame 208. The end of the conveying pipe 207 away from the water pump 206 passes through the interior of the connecting pipe 209. The outlet end of the connecting pipe 209 is fixedly connected to a nozzle 210. An adjusting component 3 is provided inside the treatment tank 201. The adjusting component 3 includes a rotating motor 301. The outer surface of the rotating motor 301 is fixedly connected to the upper surface of the connecting frame 208. A connecting gear 302 is rotatably connected to the upper surface of the connecting frame 208. The output end of the rotating motor 301 is fixedly connected to the upper surface of the connecting gear 302. Several rotating shafts 303 are rotatably connected inside the connecting frame 208. A rotating gear 304 is fixedly installed at the top of each rotating shaft 303. The outer surfaces of two adjacent rotating gears 304 mesh. The outer surface of the connecting gear 302 meshes with the outer surfaces of two of the rotating gears 304. Several concave frames 305 are fixedly installed on the bottom surface of the connecting frame 208. Each concave frame 305 has an adjusting frame 306 hinged inside. Each adjusting frame 306 has a mounting plate 307 fixedly installed on its bottom surface. The outer surface of each nozzle 210 is fixedly connected to the inner wall of the mounting plate 307. Each rotating shaft 303 has a turntable 308 fixedly installed at its bottom end. Each turntable 308 has a connecting post 309 rotatably connected to its bottom surface. The inner wall of each connecting post 309 is slidably connected to the outer surface of the adjusting frame 306. The concave frame 305 and the adjusting frame 306... All of them are concave in shape and have opposite opening directions. By rotating the motor 301 in conjunction with the connecting gear 302, several rotating gears 304 are driven to rotate, which in turn drives the rotating shaft 303, the turntable 308 and the connecting column 309 to rotate. This causes the connecting column 309 to drive the adjusting frame 306, the mounting plate 307 and the nozzle 210 to swing back and forth, thereby increasing the spraying range of the nozzle 210 and achieving the effect of spraying the inside of the treatment box 201.
[0031] Please refer to this carefully. Figure 3 Each rotating gear 304 has a connecting bearing 9 fixedly installed on its bottom surface. The bottom surface of the inner ring of each connecting bearing 9 is fixedly connected to the upper surface of the connecting frame 208. The installation of the connecting bearing 9 plays a role in stabilizing the rotating gear 304, thereby preventing the rotating gear 304 from shaking when rotating, and thus ensuring the stability of the rotating gear 304.
[0032] Please refer to this carefully. Figure 1 and Figure 5The internal structure of the casing 1 contains a detection component 4, which includes a controller 401. The right side of the controller 401 is fixedly connected to the left side of the casing 1. Two heating elements 402 are fixedly installed on the inner wall of the casing 1. An outlet pipe 403 is fixedly connected to the inner bottom wall of the casing 1. A solenoid valve 404 is fixedly connected to the outer surface of the outlet pipe 403. A filter screen 405 is fixedly installed on the inner wall of the outlet pipe 403. The controller 401 adjusts the temperature of the heating elements 402 to heat the battery, allowing workers to easily understand the battery's heat resistance temperature. The filter screen 405 filters battery fragments. Then, by opening the solenoid valve 404, the outlet pipe 403 discharges the electrolyte from the casing 1, facilitating electrolyte collection.
[0033] In use, the worker first places the battery to be tested into the casing 1, then locks the casing 1 by engaging the locking bracket 6 onto the locking block 5. The worker then adjusts the temperature of the heating element 402 via the controller 401, allowing the heating element 402 to perform temperature resistance testing on the battery. During the testing process, the worker activates the air pump 203, which pumps outside air into the casing 1. This allows the toxic gas to enter the processing chamber 201 through the air inlet pipe 202. Simultaneously, the water pump 206 sprays the chemical reagents from the storage tank 205 into the processing chamber 201 via the delivery pipe 207, connecting pipe 209, and nozzle 210, thereby discharging the chemical reagents into the processing chamber 201. The system reacts with toxic gases to purify them. Simultaneously, the power provided by the rotating motor 301 drives the connecting gear 302 to rotate, which in turn drives the rotating gear 304 to rotate. This, in turn, causes the rotating gear 304 to rotate the rotating shaft 303, turntable 308, and connecting column 309. This, in turn, causes the connecting column 309 to drive the adjusting frame 306 to oscillate back and forth, which in turn drives the mounting plate 307 and nozzle 210 to oscillate back and forth, thus increasing the spray range of the nozzle 210. This allows the toxic gases to be purified under the combined action of chemical agents and activated carbon plate 204, resulting in non-toxic gases being released into the environment. After the test is completed, the worker opens the solenoid valve 404 to collect the electrolyte.
