Referring to fig. 1 to 4, the present embodiment provides a compressor silencer 200, wherein the compressor silencer 200 is disposed on a compressor lower cylinder cover 100, and the compressor lower cylinder cover 100 is provided with an exhaust port 110 and an exhaust outlet 120. The compressor muffler 200 includes: a first muffler shell 210 and a second muffler shell 220. The first muffler shell 210 includes a body 211 and a protruding portion 212 provided on an end surface of the body 211 away from the compressor lower head 100. The protruding direction of the protruding portion 212 is far away from the compressor lower cylinder cover 100 to form a first sound-deadening chamber 213, that is, the protruding portion 212 is close to the bottom of the compressor and far away from the compressor lower cylinder cover 100. The body 211 is attached to the lower cylinder cover 100 of the compressor. Thus, the space defined by the compressor lower cylinder cover 100 and the boss 212 is the first muffling chamber 213. In addition, the protruding portion 212 is provided with a through hole 214, and the body 211 is provided with a muffler exhaust port 215. The second muffler shell 220 is a hollow structure and is sleeved on the first muffler shell 210 to form a second sound-deadening chamber 221. The first muffling chamber 213 communicates with the second muffling chamber 221 through the through hole 214. During installation, the body 211 is attached to the lower compressor cylinder cover 100, that is, the body 221 is in gapless connection with the lower compressor cylinder cover 100. At this time, the gas exhausted from the cylinder 300 can enter the second muffling chamber 221 only through the through hole 214. Further, since the second muffler shell 220 is sleeved on the first muffler shell 210, that is, the muffler exhaust port 215 is located in the second muffling chamber 221, such that the gas exhausted from the cylinder 300 passes through the second muffling chamber 221 and then is exhausted from the muffler exhaust port 215 to the compressor muffler 200, and is exhausted from the exhaust outlet 120 of the compressor lower cylinder cover 100 to the muffler connected to the compressor upper cylinder cover, and finally is exhausted out of the compressor.
The first silencing cavity 213 is limited through the lower cylinder cover 100 of the compressor and the first silencer shell 210, the second silencing cavity 221 is limited through the first silencer shell 210 and the second silencer shell 220, the first silencing cavity 213 is communicated with the second silencing cavity 221 through the through hole 214 on the protruding part 212 of the first silencer shell 210, and the compressor silencer 200 with the structure that the two silencing cavities are communicated with each other can enable gas exhausted from the cylinder 300 to pass through the second silencing cavity 221 after passing through the first silencing cavity 213, so that secondary silencing is performed on gas exhausted from the cylinder 300, and the using effect of the compressor silencer 200 is good due to the secondary silencing. After the gas exhausted from the cylinder 300 passes through the two muffling cavities formed by the compressor muffler 200, the effective flowing volume of the gas is greatly increased, so that the muffling effect of the compressor muffler 200 is good.
In one embodiment, the number of the through holes 214 is at least two, so that the path of the gas exhausted from the gas exhaust port 110 of the lower compressor head 100 passing through the compressor silencer 200 is lengthened, the impact force of the gas exhausted from the gas exhaust port 110 of the lower compressor head 100 on the compressor silencer 200 is reduced, and the silencing effect of the compressor silencer 200 is further improved.
