The side surface of the cabinet 1 is fixedly connected to a first alarm light 8, which is also fixedly connected to a second alarm light 9. When the temperature inside the cabinet 1 exceeds the standard, the first alarm light 8 lights up, and when the humidity inside the cabinet 1 exceeds the standard, the second alarm light 9 lights up to remind the staff. The data detected by the humidity detector 15 will be transmitted to the first alarm light 8, and the data detected by the temperature detector 14 will be transmitted to the second alarm light 9.

[0028] The filter assembly 7 includes a plug plate 701, a filter sponge block 702, a cover plate 703, a pull frame 704, a rotating block 705, and a fixed shaft 706. The plug plate 701 is slidably connected in the placement groove of the ventilation duct 6. A groove is arranged on the upper surface of the plug plate 701. A through hole communicating with the groove of the plug plate 701 is arranged at the center of the side surface of the plug plate 701. The filter sponge block 702 is placed in the groove of the plug plate 701. The cover plate 703 is arranged on the upper surface of the plug plate 701.
