By shaking the dehumidifier, the risk of material aging can be reduced, the dehumidifier can maintain good performance in the entire service life, and thus the service life thereof is prolonged.

[0025] One side of the cam 166 is provided with a convex surface. The connecting plate 167 is in contact with the cam 166. The cam 166 rotates to contact and extrude the connecting block 168 to move upward.

[0026] The discharging frame 165 is internally fixedly installed with a telescopic elastic rod II 1611. The free end of the telescopic elastic rod II 1611 is fixedly connected below the receiving plate 169. The receiving plate 169 moves upward to drive the telescopic end of the telescopic elastic rod II 1611 to contract and then reset.

[0027] The scraping device comprises a connecting rod 172, a sliding plate 173, a receiving block 174 and a scraping plate 176. The surface of the fixed frame 161 is provided with a sliding groove 171. The connecting rod 172 is slidingly installed inside the sliding groove 171. The sliding plate 173 is fixedly installed above the receiving plate 169. The receiving block 174 is fixedly installed on one side of the receiving plate 169 away from the cam 166. The scraping plate 176 is slidingly installed on one side of the air inlet plate 1610 away from the receiving plate 169. The scraping plate 176 moves upward to scrape the surface of the air inlet plate 1610, preventing dust and dirt from accumulating on the surface of the air inlet plate 1610 and hindering air flow. Regularly cleaning the air inlet plate 1610 can reduce the maintenance frequency caused by overheating or failure of the equipment, thereby reducing the overall maintenance cost.

[0028] The connecting rod 172 is fixed through the inner and outer walls of the sliding plate 173. A movable groove 175 is opened on the surface of the air inlet plate 1610. A receiving block 174 is slidably installed inside the movable groove 175. The receiving block 174 is fixedly connected with a scraper 176 on the side away from the receiving plate 169. The connecting rod 172 slides inside the slide groove 171, and the receiving plate 169 moves upward to drive the sliding plate 173 to slide inside the slide groove 171 along with the connecting rod 172.

[0029] When the present embodiment is working, when the inside of the power cabinet is overheated, the fan 163 rotates to drive the rotating rod 164 to rotate, the rotating rod 164 rotates to drive the cam 166 to rotate, the cam 166 rotates to contact and squeeze the connecting block 168 to move upward, the connecting block 168 moves upward to drive the receiving plate 169 to move upward, the receiving plate 169 moves upward to drive the telescopic end of the telescopic elastic rod 2 1611 to retract and then reset, the telescopic elastic rod 2 1611 resets to drive the receiving plate 169 to move downward, the receiving plate 169 moves downward to drive the connecting block 168 to move downward, the receiving plate 169 Under the action of contact and extrusion of cam 166, it moves up and down, and shakes the dehumidifier inside up and down, so that the inside can have greater contact with the receiving plate 169, thereby increasing the dehumidification effect and achieving shaking of the internal dehumidifier while heat dissipation and ventilation. During the ventilation and heat dissipation process, shaking the dehumidifier can increase the fluidity of the airflow, thereby accelerating the air circulation in the cabinet and further improving the heat dissipation effect. At the same time, by shaking the dehumidifier, the risk of material aging can be reduced, ensuring that the dehumidifier maintains good performance throughout the entire use cycle, thereby extending its service life.

[0030] When the receiving plate 169 moves upward, the sliding plate 173 is driven to move upward, and the upward movement of the sliding plate 173 drives the connecting rod 172 to move upward. Because the connecting rod 172 slides inside the slide groove 171, the upward movement of the receiving plate 169 drives the sliding plate 173 to slide inside the slide groove 171 along with the connecting rod 172. At the same time, the sliding plate 173 moves upward with the receiving plate 169 and evenly applies the dehumidifier on the surface of the receiving plate 169. By scraping, the dehumidifier can be better contacted with the moisture in the air. The surface area of ​​the dehumidifier is increased, thereby improving the water absorption efficiency and further enhancing the dehumidification effect. At the same time, when the receiving plate 169 moves upward, it drives the receiving block 174 to move upward, and the receiving block 174 moves upward, driving the scraper 176 to move upward. The scraper 176 moves upward to scrape the surface of the air inlet plate 1610 to prevent dust and dirt from accumulating on the surface of the air inlet plate 1610 and hindering air flow. At the same time, regular cleaning of the air inlet plate 1610 can reduce the frequency of maintenance due to equipment overheating or failure, thereby reducing overall maintenance costs.
