[0037] Reference Figure 1 to Figure 5 , which is the second embodiment of the utility model. This embodiment is based on the previous embodiment and is different from the previous embodiment in that: the movable plate 101 is placed in the sliding groove 102a, and the inner wall of the mounting groove 102a-1 is slidably connected with a telescopic block 103. The upper end of the telescopic block 103 is "U"-shaped, and the outer wall of the telescopic block 103 is slidably connected to the through groove 101a. The telescopic block 103 will have a contact with the triangular block 101b at a distance, and the telescopic block 103 will rise and fall along the inclined surface of the triangular block 101b; the lower end of the telescopic block 103 is fixedly connected with a spring 103a, and one end of the spring 103a is fixedly connected to one end of the mounting groove 102a-1. The spring 103a enables the telescopic block 103 to move up and down in the mounting groove 102a-1; one end of the movable plate 101 is fixed A baffle 104 is connected, and a contact rod 105 is rotatably connected to the center of the baffle 104. The baffle 104 provides support for the contact rod 105. A bidirectional torsion shaft is arranged inside the contact rod 105, and the contact rod 105 can return to the initial position after rotation. Short rods are arranged at a distance of one end on the left and right sides of the length direction of the contact rod 105, and the function of the short rods is to make the short rods deflect with the telescopic block 103 after contacting the telescopic block 103; a bevel gear 106 is fixedly connected to one end of the contact rod 105, and the bevel gear 106 is meshed with a cleaning gear 107, and the cleaning gear 107 is also a bevel gear. A cleaning member 107a is fixedly connected to the center of the cleaning gear 107, and the cleaning member 107a rotates around the center of the cleaning gear 107, so as to achieve the purpose of rotating descaling of the smoke collecting port;

[0038] Furthermore, one end of the outer wall of the first rod 201a is fixedly connected to the air collecting hood 202, and the other end is provided with an extension rod 203, and one end of the outer wall of the second rod 201b and the third rod 201c is provided with a connecting member 204; the baffle 104 is fixedly connected to the inner wall of the first rod 201a, and the function of the baffle 104 is not only to provide support for the contact rod 105, but also to be closely connected with the inner wall of the first rod 201a on all sides to block the smoke and dust to the greatest extent and prevent the smoke and dust from affecting the movable plate 101 and the fixed plate 102. A fixed rod 201a-1 is provided on one side of the inner wall of the first rod 201a; the fixed rod 201a-1 is rotatably connected to the center of the cleaning gear 107, and one end of the cleaning member 107a is in contact with the inner wall of the air collecting hood 202, that is, the cleaning member 107a is for cleaning the air collecting hood 202.

At the same time, the air collecting hood 202 is cleaned while being extended and retracted to prevent the blockage at the entrance from causing the overall collection effect. Four gear rotations will be completed during the complete extension and retraction process. During the shortening process, the two triangular blocks 101b will contact the two telescopic blocks 103 respectively, which will drive the contact rod 105 to rotate in opposite directions twice; when shortened to the limit and then extended, the two triangular blocks 101b will contact the two telescopic blocks 103 again, and the contact rod 105 will rotate in opposite directions twice again, and the dirt cleaned by the cleaning member 107a will also be collected.
