[0026] Reference Figures 10 to 12 The first intercepting block 302 and the second intercepting block 303 are both provided with an electromagnet 304, the sliding rod 306 is fixedly connected to the first intercepting block 302, and a through hole is opened on the second intercepting block 303, and the sliding rod 306 passes through the through hole of the second intercepting block 303 and is slidably connected to the second intercepting block 303; the spring 305 is sleeved on the sliding rod 306, and the spring 305 is located between the first intercepting block 302 and the second intercepting block 303; a plurality of ventilation holes 307 are opened on the second intercepting block 303, and the distance between the second intercepting block 303 and the air inlet hole 308 is greater than the distance between the first intercepting block 302 and the air inlet hole 308.
[0027] Reference Figures 1 to 7 A through hole is opened on the box cover 2, and a fan 6 passes through the through hole on the box cover 2, and a motor 4 is connected to one side of the fan 6; an odor detector 12 is fixedly connected to the inner wall of the protective box 1; a filter screen 13 is arranged under the box cover 2, and the position of the filter screen 13 corresponds to the position of the air hole 5.
[0028] By cooperating with the first interception block 302 and the second interception block 303 set in the exhaust pipe 3, the direction of airflow can be guided to avoid odor and harmful gases being directly discharged to the outside of the device, affecting external personnel, thereby improving the safety of the device.
[0029] The working principle and use process of the present invention are as follows: open the box cover 2, place the battery on the limiting assembly 10, and use the elastic ring 1001 and the limiting frame 1002 to position and fix the battery, close the box cover 2, start the motor 4 to drive the fan 6 to rotate for heat dissipation, and the cooling plate 8 also cooperates to perform heat dissipation.
[0030] The fan 6 rotates to guide the airflow to move downward, and the airflow moves downward to the bottom of the device through the gaps between the components and the heat dissipation holes 1107 on the support plate 1106. The odor detector 12 monitors the gas in the device in real time. If the gas value is normal, the gas is discharged normally through the air inlet 308 and the air vent 307 on the second interception block 303. If the gas value is abnormal, the electromagnet 304 on the first interception block 302 and the second interception block 303 is energized to generate magnetic force, and the first interception block 302 is adsorbed to the second interception block 303. During this process, the spring 305 is squeezed and the slide bar 306 slides through the through hole on the second interception block 303. At this time, since the first interception block 302 intercepts the passage on one side of the exhaust pipe 3, the gas flows to the processor 301 through the air inlet hole 308, and the gas is deodorized and harmlessly treated by the processor 301, and then discharged. When the gas value in the device returns to normal, the electromagnet 304 on the first interception block 302 and the second interception block 303 is powered off, and the spring 305 is reset, driving the slide bar 306 and the first interception block 302 to reset.
[0031] During the installation and transportation process, the first support frame 1101, the tension spring 1102, the damper 1103, the fixed block 1104 and the second support frame 1105 cooperate to switch the oblique positive and negative stiffness back and forth to support the battery placed on the support plate 1106, and the elastic ring 1001 in the limit assembly 10 can not only fix the battery but also buffer the impact, so that the battery can absorb and relieve vibration through the vibration reduction assembly 11.
[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention.
