The lock 11 closes the thermal insulation cover 1, and the muffler installation part is exposed from the middle of the first installation port 17 and the second installation port 18, and then the zipper 11 position is covered by the first cover pad 12 and the protective component 5, and the two ends of the straps 13 are passed through the middle of the corresponding fixing ring 16, and the first Velcro mother surface 15 in the middle of the strap 13 is in close contact with the corresponding first Velcro sub-surface 14.

The above structure can make the installation and disassembly of the muffler when placed inside the thermal insulation cover 1 simpler and faster. When the muffler needs to be cleaned, inspected and replaced, the thermal insulation cover 1 can be quickly disassembled by cooperating with the zipper 10 and the zipper 11, which is convenient for maintenance of the muffler. In addition, the first cover pad 12 can effectively reduce the heat leakage through the gap during use of the muffler, effectively improve the thermal insulation effect of the thermal insulation cover 1, and thus reduce the damage of heat to surrounding components.

After the muffler is placed inside the thermal insulation cover 1 and the zipper 11 is closed , pull the two fixing plates 31 outward, open the two snaps 32, and at the same time, the fixing plates 31 are elastically bent, and the handle end of the zipper 11 is placed in the middle of the two fixing plates 31, and then the two fixing plates 31 are fixed by the snaps 32, so that the zipper 11 is fixed to one end of the zipper 10, and the temperature monitor 41 is installed inside the fixing box 4. When the silencer is installed inside the insulation cover 1 and is used, the real-time temperature inside the insulation cover 1 is monitored by the temperature monitor 41. When the first cover pad 12 is fixed, the second cover pad 51 is covered At the end position of the thermal insulation cover 1, the second mounting opening 18 in one of the second cover pads 51 passes through the end of the muffler. At this time, the second Velcro sub-surface 52 is fitted with the second Velcro mother surface 53, thereby fixing the second cover pad 51 at the end position of the thermal insulation cover 1. When the muffler is installed inside the thermal insulation cover 1, the protective layer 6 is in contact with the surface of the muffler, and the elastic rod 2 and the muffler are protected by the protective layer 6.
