Description
Technical field
The utility model is related to mechanical equipment technical field, specially a kind of impedance composite muffler.
Background technology
Silencer is to allow air-flow to pass through, but can prevent or reduce a kind of device of sound transmission, is to eliminate air to move
The important measures of power noise.Silencer can stop the propagation of sound wave, it is allowed to which air-flow passes through, and be the effective work for controlling noise
Tool.Muffler currently on the market is numerous in variety, also applies to every field, considerably reduces noise, but itself physics
The property of presence will produce sound when causing its work, so present silencer completely cannot eliminate noise, noise elimination work
As when the vibrations that produce the working group inside silencer can be acted, use for a long time, by long-term between working part
Vibrations and windage can cause part absent-mindedness to come off, so as to influence the life-span.
The content of the invention
The purpose of this utility model is to provide a kind of impedance composite muffler, to solve to be proposed in above-mentioned background technology
Long-term vibration cause part to relax the problem that comes off.
To achieve the above object, the utility model provides following technical scheme：A kind of impedance composite muffler, including disappear
Sound cotton, gas outlet, reinforcement fixing device, absorption chamber, spring, expansion chambers, exhaust apparatus, muffler plate, damper, airduct, vibrations
Disk, air inlet, excessively gasket ring, pipe and vacuum layer, the surface inserting of the silencing cotton have muffler plate, connect below the gas outlet
Absorption chamber is connected to, airduct is provided with below the reinforcement fixing device, the surface inserting of the absorption chamber has spring, and spring
Periphery be surrounded with expansion chambers, expansion chambers are connected with below the exhaust apparatus, airduct is installed below the damper,
And vibrating disc is provided with below airduct, and excessively pipe is inlaid with below the air inlet, the periphery of the gasket ring is surrounded with very
Dead level.
Preferably, the absorption chamber is cellular.
Preferably, the muffler plate is the raised ribs of a plurality of strips, and its radial direction is radially set.
Preferably, the vibrating disc is substantially symmetrical about its central axis on muffler plate.
Preferably, the gasket ring is set along the axial direction of the excircle of absorption chamber.
Compared with prior art, the beneficial effects of the utility model are：The impedance composite muffler is provided with damper,
When sound is initially entered into silencer, because its pour in cause silencer produce between working group in itself rock when firm body,
Vibrations are reduced, the reduction of noise elimination quality will not be caused because of vibrations, greatly improve acoustical absorptivity, periphery is surround using vacuum layer, prevented
Outside the incoming silencer of air flow sound that inter-process is produced when eliminating the noise, gasket ring can play buffering when sound is into excessive pipe
Effect, absorption chamber, expansion chambers and exhaust apparatus are around setting, can farthest increase sound transmission stroke, decrease sound
Sound propagates dynamics, substantially reduces volume.

Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Fig. 1 is referred to, the utility model provides a kind of technical scheme：A kind of impedance composite muffler, including silencing cotton
1st, gas outlet 2, reinforcement fixing device 3, absorption chamber 4, spring 5, expansion chambers 6, exhaust apparatus 7, muffler plate 8, damper 9, airduct
10th, vibrating disc 11, air inlet 12, gasket ring 13, excessive pipe 14 and vacuum layer 15, the surface inserting of silencing cotton 1 have muffler plate 8, disappear
Sound plate 8 is the raised ribs of a plurality of strips, and its radial direction radially sets, and can be propagated in sound air-flow makes guiding its side
To, changed by the mutation in direction, weaken sound, the lower section of gas outlet 2 is connected with absorption chamber 4, strengthens the lower section of fixing device 3
It is provided with airduct 10, the surface inserting of absorption chamber 4 has spring 5, and absorption chamber 4 is cellular, and sound-absorbing effect is good, and spring 5 is outer
Collarette is wound with expansion chambers 6, and the lower section of exhaust apparatus 7 is connected with expansion chambers 6, and the lower section of damper 9 is provided with airduct 10, and airduct
10 lower section is provided with vibrating disc 11, and vibrating disc 11 is substantially symmetrical about its central axis on muffler plate 8, and erasure effect is more preferable, air inlet 12
Lower section is inlaid with excessive pipe 14, and the periphery of gasket ring 13 is surrounded with vacuum layer 15, gasket ring 13 along the excircle of absorption chamber 4 axial direction side
To setting, excessively pipe can be preferably covered, reduce friction and produce noise.
Operation principle：When using the impedance composite muffler, sound is entered by air inlet 12, after sound compression
