[0025] Among them, as shown in Figure 2As shown, the second fan 12 is connected to the outside via a mounting plate 8. The orientation of the second fan 12 can be uniformly adjusted via the mounting plate 8. A connecting frame 6 is provided around the outside of the mounting plate 8. An inner connecting ring 13 is provided on the lower end of the connecting frame 6 facing the mounting plate 8. The inner connecting ring 13 is welded and fixed to the connecting frame 6. A rubber corrugated pipe 9 is provided between the inner connecting ring 13 and the mounting plate 8. The wrapping of the rubber corrugated pipe 9 facilitates the extraction of gas. After the second fan 12 is started, the gas inside the outer shell 1 can be quickly extracted by the second fan 12 and discharged from the outlet 3.

[0026] In addition, the rubber bellows 9 is rectangular. The upper and lower ends of the rubber bellows 9 are glued to the inner connecting ring 13 and the mounting plate 8 respectively. The rubber bellows 9 can wrap the second fan 12. The expansion and contraction of the rubber bellows 9 can also adapt to the rotation of the mounting plate 8 and the second fan 12. During the rotation of the mounting plate 8, the rubber bellows 9 will be pulled and expanded, so that the mounting plate 8 does not need to rotate and stays at the corresponding angle. The second fan 12 can stably extract the gas inside the outer shell 1.

[0027] To facilitate stable angle adjustment of the mounting plate 8, an outer connecting ring 4 is provided on the outside of the connecting frame 6. The outer connecting ring 4 is embedded in the lower end of the inner shell 1 and rotatably connected to the inside of the outer shell 1. The connecting frame 6 and the outer connecting ring 4 are welded and fixed. After the outer connecting ring 4 rotates at the lower end of the inner shell 1, the orientation and angle of the second fan 12 can be adjusted. One side of the inner side of the mounting plate 8 is rotatably connected to the inner side of the outer connecting ring 4. Figure 4 As shown, a threaded rod 10 is provided at one end of the mounting plate 8 and the outer connecting ring 4 at the rotatable connection position.
