The controller 7 controls the motor 2 64 to operate, and pulls the decontamination unit 1 672 to operate through the linkage unit 671, and then removes the attachments on the outside of the heat conduction channel 62. The removed attachments fall into the collection port 6734. At this time, the pushing platform 6732 moves inside the collection port 6734, and then presses the attachments into the discharge trough 6739 and releases them from the discharge trough 6739. After the decontamination is completed, the motor 2 64 is controlled to pull the rotating plate 65 to rotate. At this time, through the installation of the linkage unit 671, the continuous operation of the decontamination unit 1 672 is avoided, allowing the cooling device to perform the cooling action.
