[0029] The working principle of this utility model:

[0030] When the utility model is in use, first, when it is necessary to utilize the waste heat of the smoke, the smoke enters the interior of the smoke delivery port 103 through the smoke delivery port 103, and then the filter 415 will filter the smoke, thereby reducing the impurities inside the smoke. After the filter 415 has filtered for a period of time, the motor 402 can be started to drive the rotating rod 403 to rotate, and then the rotating rod 403 will drive the disc 404 to rotate, and then the disc 404 will drive the position of the fixed column 405 to change, and then the fixed column 405 will drive the position of the block 408 to change, and then the block 408 will drive the rotating rod 409 to rotate. The position changes, and then the rotating rod 409 will drive the sliding rod 411 to move, and then the sliding rod 411 will drive the cleaning brush 414 to move. Since the movement trajectory of the disc 404 is a circle, when the disc 404 rotates to a certain extent, the connecting block 407 will rotate to its original position, so that the cleaning brush 414 reciprocates to scrape the surface of the filter screen 415 to prevent impurities from being blocked on the filter screen 415 and affecting the speed of smoke delivery. Secondly, the function of the first spring 413 is to assist the movement of the sliding rod 411, so that the sliding rod 411 moves more stably, thereby filtering and cleaning the impurities inside the smoke.
