The temperature and humidity sensor 21 is used to monitor the inside of the box body 1. The internal humidity is detected at any time. When it is detected that the internal humidity is high, the vacuum pump 13 is started to evacuate the inside of the box 1, and the gas enters the outlet pipe 12, pushing the sealing cover 17 upward to discharge the gas outward, and the external gas enters the air inlet channel through the filter 7. The gas pushes the rotating plate 8 to open, and the moisture in the gas is adsorbed when the gas passes through the desiccant, which can realize dehumidification and cooling of the interior.
