[0022] Working principle: The driving motor can be used to drive the exhaust fan blades 3 to rotate for exhaust and heat dissipation. At the same time, the airflow passes through the air inlet and is filtered by the filter screen 9 before entering the sealed chamber 18, and then enters the dehumidification frame 11. After being dehumidified by the dehumidification frame 11, it enters the cabinet 1, promoting the airflow inside the cabinet 1 and increasing the heat dissipation effect. At the same time, the heat sink 8 can assist the cabinet 1 in heat dissipation. When the output shaft of the driving motor rotates, it can drive the planetary gear 20 to rotate at a uniform speed. While the planetary gear 20 rotates, the teeth provided thereon are intermittently meshed with the full gear 21. , so that the rotating rod 22 rotates, and the traction rope 17 can be reeled up while the rotating rod 22 rotates, so that the torsion spring 16 is in a taut state, at this time, the rotating shaft 15 rotates, and the cleaning rod 12 rotates, and the cleaning brush on the cleaning rod 12 is used to clean the filter 9.

When the material-dispensing shaft 19 moves upward, the desiccant particles inside the dehumidification screen frame 11 can be pulled upward through the material-dispensing plate provided thereon. When the traction rope 17 moves downward under the tension of the torsion spring 16, the material-dispensing shaft 19 can be driven to move downward.
