Abstract
A suction muffler is provided. The suction muffler has a housing assembly, at least one partition plate and a first tube. The housing assembly defines a cavity and has a suction port and a discharge port. The partition plate is provided in the cavity to divide the cavity into at least two muffler cavities. The two muffler cavities each has a first muffler cavity and a second muffler cavity. The partition plate defines a penetrating hole to communicate the first muffler cavity with the second muffler cavity. The suction port corresponds to the first muffler cavity. The first tube has a portion provided in the first muffler cavity. One end of the first tube is in communication with the suction port. The other end of the first tube passes through the partition plate and is in communication with the second muffler cavity.
