[0027] In actual application, when the temperature in the box body 1 reaches a preset value, the temperature sensor 11 will start the hair dryer 12 to blow air into the box body 1, and then the air flow will flow along the air duct 8 to take away the heat emitted by the heat dissipation fins 7, and then blow it out through the heat dissipation holes 3 through the arranged fan 9; and the dust accumulated in the box body 1 can also come into the heat dissipation holes 3 along with the air flow of the hair dryer 12, and be blocked by the filter plate 13, and then when the infrared scanner 16 detects that there is too much dust on the filter plate 13, it will automatically start the motor 15 to make the rotating rod 14 rotate, and then the inside and outside of the filter plate 13 will change.
