The drying fan 92 blows the air to the heating wire 94 for heating. The heated air is sent to the porous plate 96 through the air expansion box 95. The air is evenly sprayed onto the plastic parts from the porous plate 96. When the humidity in the machine body 11 is high, the wind shield 86 and the U-shaped baffle 83 are lowered to allow all the air to enter the dehumidification module 7. The dehumidification module 7 is started to reduce the humidity. Finally, when removing harmful gases, the wind shield 86 is lowered, the U-shaped baffle 83 is lifted, and the air enters the purification box 81. The activated carbon adsorption plate 82 adsorbs harmful gases in the air.
