The invention discloses a silencer. The silencer comprises a hollow cavity defined by a first bottom surface, a second bottom surface and a side wall; the side wall is connected with the first bottomsurface and the second bottom surface; a gas inlet is formed in one end of the silencer, and a gas outlet is formed in the other opposite end of the silencer; the cavity is divided into a plurality ofchambers in the axial direction; the chambers include the first chamber adjacent to the first bottom surface, the second chamber adjacent to the second bottom surface and the middle chamber located between the first chamber and the second chamber; the gas inlet communicates with gas of the middle chamber; the middle chamber communicates with gas of the second chamber; the first chamber communicates with gas of the second chamber; and the gas outlet communicates with gas of the first chamber.
