Embodiment Construction

[0016] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0017] Such as figure 1 As shown, a muffler includes an inner cylinder 2 and an outer cylinder 1, and an outwardly protruding cavity 3 is distributed on the outer cylinder 1. The inner cylinder 2 is sleeved in the outer cylinder 1, and the space between the inner cylinder and the outer cylinder is filled with Porous filler 7, the inside of the inner cylinder is provided with a grid consisting of a horizontal frame 4 and a vertical frame 5, and a dispersing sheet 6 is installed on the partition of the grid, and the dispersing sheet is arranged in a V shape on the vertical frame, and the V of the dispersing sheet is arranged on the vertical frame. The oblique plane is...

Abstract

The invention provides a silencer. Porous filling is arranged between an inner barrel and an outer barrel, the gap between the inner barrel and the outer barrel and the porous filling can be utilized to absorb part of noise, moreover, because outwardly raised cavities arranged on the outer barrel are larger than the circle of the outer barrel and are arranged at intervals, part of the noise can be absorbed stage by stage, the decreased noise is then absorbed by the next outwardly raised cavity, and scattered sheets are arranged on a plurality of grids arranged in the inner barrel, and are provided with noise-absorbing layers formed by a substance with a noise-absorbing effect to absorb noise. Because the grids are separately arranged, the grids can decrease noise stage by stage as well, so that noise can be gradually absorbed, and thereby a good silencing effect can be achieved.

Description

technical field [0001] The invention relates to a muffler and belongs to the field of mufflers. Background technique [0002] Noise is generated at the exhaust port, and a muffler is installed to eliminate this noise. The muffler contains an outer tube and an inner tube. The muffler is generally composed of an outer tube and an inner tube. The upper end of the outer tube is connected to the exhaust port of the corresponding equipment. When working, the noise in the gas entering the outer tube from the upper end of the outer tube enters the inner tube, is absorbed by the tube wall of the inner tube, and then conducts sound insulation through the distance between the inner tube and the outer tube to achieve the purpose of reducing noise. However, it is found in work practice that the noise reduction effect is poor. [0003] In view of this, the present invention is proposed. Contents of the invention [0004] The technical problem to be solved by the present invention is ...
