[0147] Specifically, the frame 616 can provide a space for opening the through groove 618 under the support of the first furnace chamber 2 and the second furnace chamber 201. The cleaning member includes: a second arc plate 610, fixed to the top of the connecting block 609, and there are two of them, respectively located inside the first furnace chamber 2 and the second furnace chamber 201. Three side plates 612 are symmetrically fixed to the inner side of the second arc plate 610. A spring 613 is installed on the top of the side plate 612, and the spring 613 is connected to the inner side of the top walls of the first furnace chamber 2 and the second furnace chamber 201. A first connecting bar 614 is installed on the front of the second arc plate 610, and the front of the first connecting bar 614 is connected to the first slider 615. A partition rod 617 is fixed at the center line position inside the frame 616. Limiting plates 619 are respectively fixed on the opposite sides of the first slider 615 and the second slider 621, and the limiting plates 619 penetrate through the through groove 618. A transmission rope 620 has one end fixed to the second slider 621, the other end fixed to the first slider 615, and movably penetrates through the partition rod 617. A second connecting bar 622 is fixed to the back of the second slider 621. A support plate 623 is installed on the back of the second connecting bar 622, and the support plate 623 is located below the first arc plate 606.

The spring 613 can provide support for the second arc plate 610 through the side plate 612 under the support of the first furnace chamber 2 and the second furnace chamber 201.

[0148] In the actual application process of this embodiment, when the ferrule 605 is connected to the guide bar 611 and the high-valve cylinder 407 is controlled to extend, the ferrule 605 will drive the support plate 607 and the side rod 608 to move downward together through the first arc plate 606. The side rod 608 will drive the second arc plate 610 to move downward together through the connecting block 609. The second arc plate 610 will drive the side plate 612 to move together by using an external force, causing the side plate 612 to stretch the spring 613 to elongate. At the same time, the second arc plate 610 will drive the first slider 615 to move downward along the gap between the frame 616 and the partition rod 617 through the first connecting bar 614 under the action of an external force. At the same time, the first slider 615 will drive the limit plate 619 to move downward together under the guiding and limiting cooperation of the through groove 618 and the frame 616, causing one end of the transmission rope 620 to be pulled by the first slider 615 during the movement. The transmission rope 620 will use the other end to pull the second slider 621 to move upward along the gap between the frame 616 and the partition rod 617 under the action of an external force and the support of the partition rod 617. The second slider 621 will drive the limit plate 619 to move upward along the through groove 618 together, so that the second slider 621 can drive the frame plate 623 to move upward together through the second connecting bar 622 under the action of an external force. Furthermore, the frame plate 623 and the second arc plate 610 can drive the cleaning brush 624 to move together under the action of an external force, causing the two cleaning brushes 624 to approach each other. The cleaning brush 624 will use friction and its own material to initially brush and clean the inner wall of the first furnace 2 or the second furnace 201 during the movement, improving functionality. When the electric rod 602 is controlled to extend and the ferrule 605 is separated from the guide bar 611, the spring 613 will pull the second arc plate 610 to move upward through the side plate 612 by using the rebounding force under the support of the first furnace 2 and the second furnace 201. Furthermore, the second arc plate 610 will cooperate with the first slider 615, the second slider 621, the transmission rope 620 and gravity, causing the frame plate 623 to move downward to return to its original position.
