Abstract
The utility model relates to the technical field of automobile components, in particular to an exhaust silencer. The exhaust silencer comprises a silencer body, an air inlet, an air outlet, a thick hole noise reduction layer, a slim hole noise reduction layer, noise reduction cotton and cutting strips. The air inlet is formed in one side of the silencer body, the air outlet is formed in the other side of the silencer body, the thick hole noise reduction layer is arranged on one side in the silencer body, the slim hole noise reduction layer is arranged on the outer portion of the thick hole noise reduction layer, the space between the thick hole noise reduction layer and the slim hole noise reduction layer is filled with the sound reduction cotton, the cutting strips are arranged on one side of the slim hole noise reduction layer, and air vents are formed in the cutting strips. The exhaust silencer is simple, compact and reasonable in structure, convenient and fast to assemble and reliable in connection, reduces noise produced when an engine exhausts air through repeating oscillation, lowers air flow speed through the cutting strips, reduces pressure inside the silencer body, enhances the noise reduction effect, greatly improves the reliability of the work of the silencer, and is easy to use and popularize.
Description
Technical field
The utility model relates to a kind of technical field of auto parts and components, especially a kind of muffler.
Background technique
Silencing apparatus is mounted in the low noise device that falls on the air-flow path of aerodynamic force equipment (as blower, air compressor) or in inlet and exhaust system.Silencing apparatus can stop the propagation of sound wave, allows air-flow to pass through, and is the effective tool of controlling noise.Existing baffler air-flow in body during to outer discharging, excessive velocities, the body internal pressure is larger, exhaust easily is obstructed, thereby has affected the effect of noise reduction, greatly reduces the reliability of baffler work.
The model utility content
In order to overcome the deficiency that existing baffler gas pressure is large, exhaust is obstructed, erasure effect is poor and functional reliability is low, the utility model provides a kind of muffler.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of muffler, comprise body, suction port, air outlet, gross porosity noise reduction layer, pore noise reduction layer, silencing cotton and cutting rod, body one side is provided with suction port, opposite side is provided with the air outlet, in body, a side is provided with gross porosity noise reduction layer, gross porosity noise reduction layer outside is provided with pore noise reduction layer, is filled with silencing cotton between gross porosity noise reduction layer and pore noise reduction layer, and pore noise reduction layer one side is provided with cutting rod.
According to another embodiment of the present utility model, comprise that further cutting rod is provided with pore.
The beneficial effects of the utility model are, this muffler is simple in structure, compact and reasonable, easy to assembly quick, connect reliably, discharge by repeatedly shaking the decay engine exhaust noise that produces, reduce simultaneously the speed of air-flow by cutting rod, reduce the pressure of body inside, strengthened the effect of noise reduction, greatly improved the reliability of baffler work, be easy to use and promote.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. bodies in figure, 2. suction port, 3. air outlet, 4. gross porosity noise reduction layer, 5. pore noise reduction layer, 6. silencing cotton, 7. cutting rod, 8. pore.
Embodiment
Structural representation of the present utility model as Fig. 1, a kind of muffler, comprise body 1, suction port 2, air outlet 3, gross porosity noise reduction layer 4, pore noise reduction layer 5, silencing cotton 6, cutting rod 7 and pore 8, body 1 one sides are provided with suction port 2, opposite side is provided with air outlet 3, in body 1, a side is provided with gross porosity noise reduction layer 4, gross porosity noise reduction layer 4 outside are provided with pore noise reduction layer 5, be filled with silencing cotton 6 between gross porosity noise reduction layer 4 and pore noise reduction layer 5, pore noise reduction layer 5 one side are provided with cutting rod 7, and cutting rod 7 is provided with pore 8.
During use, gas enters from the suction port 2 of body 1 one sides, in body 1, a side is provided with gross porosity noise reduction layer 4, and gross porosity noise reduction layer 4 outside are provided with pore noise reduction layer 5, are filled with silencing cotton 6 between gross porosity noise reduction layer 4 and pore noise reduction layer 5, gas permeation gross porosity noise reduction layer 4 and pore noise reduction layer 5, because the diameter in hole differs, discharge by concussion decay waste gas repeatedly the noise that produces, pore noise reduction layer 5 one side are provided with cutting rod 7, cutting rod 7 is provided with pore 8, can reduce the speed that air-flow passes.This muffler is simple in structure, compact and reasonable, easy to assembly quick, connect reliable, discharge by repeatedly shaking the decay engine exhaust noise that produces, reduce simultaneously the speed of air-flow by cutting rod, reduce the pressure of body inside, strengthened the effect of noise reduction, greatly improved the reliability of baffler work, be easy to use and promote.
