A muffler includes a housing and a partition member. The housing includes a cavity, a gas inlet, and a gas outlet. The gas inlet and the gas outlet are respectively in communication with the cavity. The partition member is disposed in the housing. The partition member partitions the cavity into a resonant cavity and a muffling cavity that are isolated from each other. The resonant cavity is in communication only with the gas inlet. The muffling cavity is in communication with both the gas inlet and the gas outlet.
