[0023] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 5 The stabilizing and reinforcing mechanism 6 includes an installing angle plate 20. The left side of the installing angle plate 20 is fixedly connected to the mechanism body 1. The opposite side of the installing angle plate 20 is fixedly connected with a U-shaped frame plate 21. Both sides of the opposite side of the U-shaped frame plate 21 are penetrated and fixedly connected with a driving push rod 22.

This mechanism can effectively reinforce the connection between the device and the muffler to avoid gaps in the connection after long-term use, thereby ensuring smooth operation and extending the service life, thereby completing the stable reinforcement process. When the muffler is started, the auxiliary fan 14 of the device should also be started by the controller. The suction force generated will suck air from the air inlet hole at the entrance.
