At this time, the spring II47 Push the square plate 46 again to get close to the motor VI44, and the sliding rod 50 is separated from the blocking plate 51. After the cleaning block I53 and the cleaning block II54 are in contact, the motor V35 is started in reverse, so that the rotating rod I40 and the rotating rod II41 are far away from each other, and at the same time the rotating rod I40 and rotating rod II41 are hindered by the cleaning block I53 to rotate, and finally the rotating rod I40 and rotating rod II41 return to both sides of the bottom case 1, and the wedge plate 48 pushes the cleaning block I53 and the cleaning block under the action of the spring I45 and the spring II47 II54 slides away from the direction of the motor VI44, and under the action of the inclined plate 52, the cleaning block I53 and the cleaning block II54 are tightly attached to each other. During the movement of the cleaning block I53 and the cleaning block II54, they are separated from the blocking plate 51. Under the contraction of the spring II 47, the sliding rod 50 contacts the blocking plate 51 again, pushes the blocking plate 51 back to its original position, and seals. The 49 rotation drives the cleaning block I53 and II54 to slide in the inclined plate II28 and the inclined plate I27 through the cooperation with the threaded hole, and finally all the dust is scraped out, and when moving to the opening of the ash outlet 42 and the closing plate 43, a small The spring 56 bounces the cleaning block I53 and the cleaning block II54 apart.
