Embodiment Construction

[0019] Preferred embodiments of the present invention will be described in detail below.

[0020] see figure 1 , a muffler, including a muffler main body 1, an intake pipe 2 and an exhaust pipe 3, characterized in that: the inside of the muffler main body 1 is divided into chamber I 7, chamber II 8 and chamber III 9 by partitions 4 and 5 in sequence , the exhaust end of the inlet pipe 2 extends into the chamber I 7 and communicates with the chamber I 7, the chamber I 7 communicates with the chamber III9 through the pipe I 10, and the chamber III9 and the chamber II 8 pass through the pipe II 20, and the intake end of the exhaust pipe 3 communicates with the chamber II 8. The muffler main body 1 includes an inner shell 11 and an outer shell 12, the inner shell 11 is set inside the outer shell 12, a sound-absorbing and heat-insulating layer 6 is arranged between the inner shell 11 and the outer shell 12, and the sound-absorbing and heat-insulating layer 6 Glass fiber felt can ...

Abstract

The invention relates to the technical field of silencers, and particularly provides a silencer which is better in noise elimination effect. The silencer comprises a silencer main body, an air inlet pipe, an exhaust pipe and a strip outer cover, wherein the silencer main body is accommodated in at least part of the strip outer cover; the strip outer cover and the silencer main body are fixed through screws; the air inlet direction of the air inlet pipe is perpendicular to the exhaust direction of the exhaust pipe; an exhaust port is formed on the strip outer cover; and the exhaust pipe is connected with the exhaust port after being bent. In the silencer, by arranging a shell, a certain silencing and heat insulation effect can be enhanced, and the silencer is more attractive in appearance;the air inlet direction of the air inlet pipe is perpendicular to the exhaust direction of the exhaust pipe, so more collision can be produced during flowing of airflow, and the disorder degree of the airflow is increased to achieve a better silencing effect; and the exhaust pipe is bent, so nearly axial waves in sound waves can be absorbed and reflected at a bending position, and the energy of the nearly axial waves can be transformed into the energy of oblique waves during bending to be easily absorbed.

Description

technical field [0001] The invention relates to the technical field of mufflers. Background technique [0002] Internal combustion engines, air compressors and other devices, the airflow generated during their operation will make a huge noise, therefore, mufflers are needed to eliminate aerodynamic noise, prevent sound transmission and allow airflow to pass through. [0003] However, current mufflers are less effective at eliminating noise. Contents of the invention [0004] In view of this, the object of the present invention is to provide a strip muffler with better noise elimination effect. [0005] The object of the present invention is achieved like this: a bar-shaped muffler includes a muffler main body, an intake pipe and an exhaust pipe; The main body of the muffler is fixed by screws, and the air intake direction of the air intake pipe is perpendicular to the exhaust air direction of the exhaust pipe. The strip-shaped outer cover is provided with an air outlet, ...
