The first control switch and the second control switch in the present embodiment will be described in more detail below with two examples;
when the first tuyere 901 is opened and the second tuyere 902 is closed, the worker can rotate the baffle 14 from the second tuyere 902 to the first tuyere 901 only by rotating the rotating shaft 13 by 180 degrees or by other angles, so that the baffle 14 blocks the first tuyere 901, and the first tuyere 901 is closed or partially closed.
When the third air opening 1001 is opened and the fourth air opening 1002 is closed, the worker can rotate the baffle plate 14 from the fourth air opening 1002 to the third air opening 1001 only by rotating the rotating shaft 13 by 180 degrees or rotating the rotating shaft by other angles, so that the baffle plate 14 blocks the third air opening 1001 to complete the closing or partial closing of the third air opening 1001.
Furthermore, ventilation plates 15 are mounted on the inner side wall of the third side 12, the inner side wall of the fourth side 6, the inner side wall of the first side 4 and the inner side wall of the sixth side 8;
a plurality of vent holes 16 are formed in the vent plate 15;
it should be noted that, with the above-described design, the wind can flow from the ventilation holes 16 of the ventilation plate 15, so that the wind flows more regularly, thereby preventing the wind from flowing disorderly in the box body 3 and preventing the turbulent flow from being generated in the box body 3.
