Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 to 5, in the present embodiment, a set of muffler brackets is respectively disposed at a position close to a fan 8 and a position far away from the fan 8 at the bottom of a muffler housing 7, and each muffler bracket includes a first support frame 1, a second support frame 2, and an adjusting mechanism, where the first support frame 1 is connected with the bottom of the muffler housing 7, the second support frame 2 is disposed below the first support frame 1, and the adjusting mechanism is disposed between the first support frame 1 and the second support frame 2.

The first support frame 1 comprises a first cross rod, a first vertical rod and a second vertical rod, wherein the first vertical rod and the second vertical rod are symmetrically arranged at two ends of the first cross rod and are perpendicular to the first cross rod, the lower ends of the first vertical rod and the second vertical rod are respectively welded with two ends of the first cross rod, and the upper ends of the first vertical rod and the second vertical rod are respectively welded with the bottom of the silencer shell 7; the second support frame 2 comprises a second cross rod, a third vertical rod and a fourth vertical rod, wherein the third vertical rod and the fourth vertical rod are symmetrically arranged at two ends of the second cross rod, the second cross rod is close to the first cross rod, the second cross rod is parallel to the first cross rod, one ends of the third vertical rod and the fourth vertical rod are respectively welded with two ends of the second cross rod, and the other end of the third vertical rod deviates from the first cross rod.
