Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are only some embodiments, not all embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Example 1
This embodiment provides a amortization formula of circling round of air current muffler of breathing in, as shown in figure 1, including breathing pipe 1, amortization chamber and outlet duct 2, the amortization intracavity is provided with baffle 3 will the amortization chamber is separated for left chamber 4 and right chamber 5, and wherein left chamber 4 and breathing pipe 1 intercommunication, left chamber 4 and right chamber 5 are through setting up 6 intercommunications of communicating pipe on baffle 3, and right intracavity 5 is provided with baffle 7. The baffle 7 is arc-shaped, and the concave surface is opposite to the first communicating pipe 6. The right cavity 5 is communicated with the air outlet pipe 2 above through a communicating pipe II 8.
The working principle of the device is as follows: high-pressure draught flows into the left chamber 4 of amortization chamber from breathing pipe 1 in, utilize breathing pipe 1 and the cross section difference of left chamber 4 to expand the amortization, then the air current passes through communicating pipe 6 that sets up on baffle 3 and flows into right chamber 5 in, because be provided with curved baffle 7 in the right chamber 5, the air current can produce under the effect of baffle 7 and circle round, reflect the sound source direction back to the sound wave, make the wave crest reflection of air current sound wave and the trough of the sound wave of emergence source direction superpose each other, thereby the sound wave frequency has been reduced, reach the purpose of making an uproar, utilize the cross section difference of communicating pipe 6 and right chamber 5 to expand the amortization simultaneously. The pulse of air current is showing to reduce in right chamber 5, and the effectual noise cancelling effect that has reached falls the purpose of making an uproar, then the air current is through two 8 flows from outlet duct 2 of communicating pipe.
Example 2
The present embodiment is different from embodiment 1 in that: as shown in fig. 2-3, the baffle 7 is arranged in an S-shape; an air suction rubber sleeve 10 is arranged at an air suction port of the air suction pipe 1; and two salient points 9 are arranged around the air outlet of the air outlet pipe 2.
The S-shaped baffle 7 can make the airflow generate multiple convolution and reflect the sound wave of the airflow multiple times, so that the noise reduction effect is better. And set up bump 9 around the gas outlet of outlet duct 2 for when being connected the outlet duct 2 of this muffler with the cylinder head cooperation of compressor, there is the gap between amortization chamber and the cylinder head, thereby is favorable to the heat dissipation of outlet duct 2. The high temperature of the cylinder head component can be effectively prevented from being transmitted to the silencing cavity, so that the temperature of gas in the silencing cavity is increased, the high-temperature gas can enter the cylinder head again and be compressed to generate higher-temperature gas, and the performance of the compressor is affected due to the fact that the parts of the cylinder head are damaged.
