Abstract

The invention discloses a medium-sized silencer which comprises a silencer shell. An upper heat-insulation and sound-insulation cover and a lower heat-insulation and sound-insulation cover are connected outside the silencer shell through bolts, a mesh plate is arranged on the inner wall of the silencer shell, stainless steel silk floss formed in the mode that stainless steel materials are cut to be filamentous is fixedly arranged on the mesh plate, an opening is formed in the position, corresponding to an air outlet pipe of the silencer, of the upper heat-insulation and sound-insulation cover, and the air outlet pipe of the silencer extends from inside to outside through the opening. According to the medium-sized silencer, due to the fact that the heat-insulation and sound-insulation covers are arranged outside the silencer shell, the medium-sized silencer has the advantages of being high in strength and good in noise reduction effect.

Description

technical field [0001] The invention relates to a muffler, in particular to a medium-sized muffler with a heat-insulating and sound-insulating cover connected with bolts on the muffler. Background technique [0002] In lawn mowers, generators and other products, two-stroke and four-stroke engines are often used when the engine is started. The exhaust gas from the engine is discharged through the muffler, resulting in a high temperature of the muffler shell (especially the muffler with a catalyst added to the two-stroke engine) , the temperature of the casing is high and cannot be touched by hands. Contents of the invention [0003] The purpose of the present invention is to provide a medium-sized muffler with a simple structure and easy to use, and a heat-insulating and sound-insulating cover outside the muffler shell to solve the problem of the temperature of the muffler shell caused by the high temperature of the exhaust gas discharged by the engine in the existing muffl...
