Embodiment 1
The embodiment of the present invention provides a kind of muffler, and Fig. 1 is a signal of the muffler of the embodiment of the present invention 1
Figure.As shown in Figure 1, muffler 100 includes air inlet pipe 101, cavity 102, exhaust pipe 103 and opening/closing unit 104,
Wherein, for air inlet pipe 101 for guiding gas to cavity 102, exhaust pipe 103 has exhaust outlet 105, cavity
Gas in 102 is discharged by the exhaust outlet 105 of exhaust pipe 103, and opening/closing unit 104 is opened and closed exhaust pipe according to the preset period
103 exhaust outlet 105.
In the present embodiment, which can be used in the various equipment for generating exhaust, for example, oxygenerator etc..
The embodiment of the present invention does not limit the type of the application apparatus of the muffler.
In the present embodiment, successively pass through air inlet pipe 101, cavity 102, exhaust pipe into the gas of muffler 100
103 and be discharged from exhaust outlet 105, which buffers in cavity 102.
In the present embodiment, the size of air inlet pipe 101, cavity 102 and exhaust pipe 103 can be set according to actual needs
It sets.
For example, by the internal diameter of air inlet pipe 101 be set greater than or equal to the equipment being connect with muffler 100 exhaust
The internal diameter of pipe.
For example, setting identical as air inlet pipe 101 for the internal diameter of exhaust pipe 103, in addition, the internal diameter of cavity 102 is arranged
For the internal diameter for being significantly greater than air inlet pipe 101 and exhaust pipe 103, the length of cavity 102 is set greater than air inlet pipe 101 and exhaust
The length of pipe 103.

206 open exhaust outlet 205.
In the present embodiment, which can be the various structures that can generate restoring force.
For example, the reply portion 207 is torsional spring, the second closure 206 can be produced around the axis overturning where the torsional spring, torsional spring
The raw restoring force for making the second closure 206 closing exhaust outlet 205.
In the present embodiment, which can determine according to actual needs.For example, the preset threshold value is spring
Restoring force subtract the numerical value after the gravity of the second closure 206.
In the present embodiment, in exhaust process, the gas of discharge is buffered and is accumulated in cavity 202, when accumulation to one
When determining degree, gas is greater than reply portion 207 to the sum of the gravity of pressure and the second closure 206 that the second closure 206 generates
The restoring force of generation, so that the second closure 206 downwardly turns over to open exhaust outlet 205, at this point, exhaust process is tied substantially
Beam, the noise of generation are also eliminated in cavity 202 substantially, therefore, even if opening exhaust outlet 205 at this time, can also prevent from making an uproar
The outflow of sound effectively eliminates the noise that exhaust generates, also, due to being vented when the gas in cavity 202 is accumulated to a certain extent
Mouth 205 automatically opens, therefore gas can smoothly be discharged, to ensure that the performance of the equipment using the muffler.
In the present embodiment, the upper surface of the second closure 206 can also have seal, to further increase muffler
Airtightness.The seal is referred to the record in embodiment 1, and details are not described herein again.
As can be seen from the above embodiments, by the way that opening/closing unit is arranged, and according to the preset period or it is based on the intracorporal gas of chamber
It is opened and closed the exhaust outlet of exhaust pipe, exhaust outlet can be closed in necessary period and effectively disappeared so as to preventing the outflow of noise
Except the noise that exhaust generates, also, due to not needing to add noise-reducing structure or quieter material in the cavity, so that muffler
Interior gas can smoothly be discharged, to ensure that the performance of the equipment using the muffler.
