[0034] Working principle: When in use, the connecting outer frame shell 101 is installed at the air duct input end. When air enters, the flexible heating rod body 109 is powered on. The flexible heating rod body 109 generates heat and heats the heat conduction tube 108. When the heat conduction tube 108 is heated, the air flow is heated, making the incoming air rise stably. When cleaning the dust, start the electromagnet 506 and apply an intermittent switch current to the electromagnet 506. The electromagnet 506 is periodically powered on and off. When the electromagnet 506 is powered on and off, the armature 504 is periodically attracted and separated. The vibration push-pull block 503 slides back and forth periodically along the guide slide column 502. At the same time, the vibration push-pull block 503 drives the active lever 404 to swing back and forth through the connecting rod 507, making the long rotating shaft 402 rotate back and forth. The long rotating shaft 402 drives the synchronous rod 405 through the synchronous lever 403, causing all the synchronous levers 403 to swing synchronously. The short rotating shaft 401 rotates synchronously with the long rotating shaft 402. All the switch hammers 406 swing periodically. When swinging, the striking bar 408 periodically strikes the inner wall of the dust falling port 208, making the whole device vibrate and loosening the dust on the surface of the heat conduction tube 108. Then start the wiping motor 309 to rotate forward and backward periodically. When the wiping motor 309 rotates, it drives the main threaded column 307 to rotate synchronously. The main threaded column 307 drives the secondary threaded column 308 to rotate synchronously through the transmission between the active synchronous pulley 310, the driven synchronous pulley 311 and the synchronous belt 312. When the main threaded column 307 and the secondary threaded column 308 rotate, they respectively push the two threaded cylinders 303 to lift synchronously, so that the lifting wiping plate 301 lifts and lowers periodically. The brush ring 305 periodically wipes and removes the dust on the surface of the heat conduction tube 108. The dust is wiped and falls onto the upper surface of the lower support frame 204, and then falls into the dust collection drawer 202 along the dust falling port 208 with the vibration. After the dust removal is completed, stop the reset of the closing strip 407 to close the dust falling port 208.
