The top of the box body 1 is provided with a hole and fixedly connected to a wire mesh 11. The top of the box body 1 is located above the wire mesh 11 and is fixedly connected to a frame body 5, and a cooling device 6 is fixedly connected to the outside of the frame body 5. An air pipe 4 is fixedly connected between the frame body 5 and the pump 3; the top wall and the bottom wall of the cavity of the frame body 5 are fixedly connected to a plurality of plates 10; the upper end of the cavity of the box body 1 is fixedly connected to a water collecting plate 12, and the water collecting plate 12 separates the cavity of the box body 1; the inner wall of the cavity of the box body 1 is fixedly connected to a heating device 13; the lower ends of the left and right side walls of the cavity of the box body 1 are provided with slide grooves 14, and the slide grooves 14 are slidably connected to the drawers 9; the upper ends of the front and rear walls of the box body 1 are also fixedly connected to a pipe nozzle 7 for controlling the amount of water above the water collecting plate 12.

[0025] A microprocessor is installed inside the box 1. A humidity detector for monitoring the humidity inside the box 1 and a temperature detector for monitoring the temperature inside the box 1 are also installed inside the box 1. The microprocessor controls the start and close of the solenoid valve 2 based on the measurement data of the humidity detector and the temperature detector.

[0026] The pumps 3 on the left and right sides of the box body 1 work in opposite directions.

[0027] The plate body 10 is an aluminum plate with good thermal conductivity, and the length of the plate body 10 is greater than half of the height of the frame body 5 .

[0028] The drawer 9 is slidably connected to the slide groove 14 , the drawer 9 and the box body 1 are magnetically connected, and a limiter 8 for limiting the displacement of the drawer 9 on the slide groove 14 is fixedly connected to the front side of the box body 1 .

[0029] The water collecting plate 12 is a bilaterally symmetrical inclined plate, and the horizontal height at the left and right central axes is the lowest. The pipe opening 7 is connected to the lowest point on the top of the water collecting plate 12 .

[0030] Working principle: The battery is placed on the top of the drawer 9, the drawer 9 is closed, and the drawer 9 is limited by the limiter 8;

[0031] When a high temperature environment is required, the heating device 13 is turned on, and the pump 3 is turned on at the same time, and the pump 3 circulates the air inside the box 1 to make the heating uniform;

[0032] When a low temperature environment is required, the cooling device 6 is turned on, and the cooling device 6 cools the plate body 10 inside the frame body 5. At the same time, the pump 3 is turned on, so that the air in the box body 1 is constantly in contact with the plate body 10 and heat exchange cooling occurs, and the air is repeatedly circulated until the air is cooled;

[0033] When a hot and humid environment is required, a certain amount of water is injected from the nozzle 7 to the top of the water collecting plate 12, and the heating device 13 and the pump 3 are turned on, so that the pump 3 circulates the heated gas into the frame 5, and at the same time, the gas passes from the steel mesh 11 to the top of the water collecting plate 12 and quickly evaporates the water on the top of the water collecting plate 12 and is evenly mixed by the pump 3, and the measured value of the humidity detector is waited to reach the set value, and the microprocessor closes the solenoid valve 2 and the pump 3;

[0034] When the humid and hot environment needs to be dried, the cooling device 6 is turned on to cool the plate body 10, and the pump 3 is started at the same time. The humid and hot air contacts the cooled plate body 10 and is condensed into liquid water. The circulation contacts the gas with the plate body 10, and the accumulated liquid water rolls down on the plate body 10 and enters the top of the water collecting plate 12 from the steel mesh 11. The nozzle 7 is opened to discharge the liquid water.

[0035] When the battery explodes, the gas pressure increases rapidly, causing the magnetic connection between the drawer 9 and the box 1 to fail, and the stopper 8 to break, and the drawer 9 slides on the slide 14, the gas pressure is released and reduced, and the end of the drawer 9 is clamped on the slide 14, which is useful for extending the service life of the device;

[0036] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
