Improved muffler structure

Abstract

The invention provides an improved muffler structure, which can be used for effectively preventing air current in upper and lower cavities of the muffler from being mixed and ensuring the muffling effect. The improved muffler structure comprises a muffler shell and a muffler core, wherein the muffler core is arranged in the muffler shell; the outer side of the muffler core is provided with a bump; and the muffler shell is partitioned into two cavities. The improved muffler structure is characterized in that: the inner side of the muffler shell is provided with a muffler shell bump which is matched with the bump.

Description

technical field [0001] The invention relates to the technical field of supercharger components, in particular to an improved muffler structure. Background technique [0002] After being pressurized by the supercharger, there is a strong pressure and flow velocity in the air blown out from the outlet of the pressure casing. When it passes through the long pressure casing flow channel, it will produce squealing and noise, which will cause the supercharger to work incorrectly. Stable and abnormal vibration will shorten the life of the supercharger, affect the normal operation of the engine, and generate noise. In order to eliminate this phenomenon, a muffler is installed. For the existing muffler, see figure 1 , which includes a muffler shell 1 and a muffler core 2, a protrusion 3 is arranged on the muffler core, and the muffler shell 1 is divided into upper and lower cavities 4-1, 4-2. In order to facilitate the installation of the muffler core, the muffler core 2 is usually l...

[0002] After being pressurized by the supercharger, there is a strong pressure and flow velocity in the air blown out from the outlet of the pressure casing. When it passes through the long pressure casing flow channel, it will produce squealing and noise, which will cause the supercharger to work incorrectly. Stable and abnormal vibration will shorten the life of the supercharger, affect the normal operation of the engine, and generate noise. In order to eliminate this phenomenon, a muffler is installed. For the existing muffler, see figure 1 , which includes a muffler shell 1 and a muffler core 2, a protrusion 3 is arranged on the muffler core, and the muffler shell 1 is divided into upper and lower cavities 4-1, 4-2. In order to facilitate the installation of the muffler core, the muffler core 2 is usually larger than the muffler shell 1 small, at this time, the air flow of the upper and lower cavities 4-1 and 4-2 will collide, which will affect the muffler's muffler effect
