Abstract:
A noise-cancelling structure of an air cleaner comprises a tube-shaped air circulation main body (10) and a sound-muffling main body (20) provided at an outer circumference of the air circulation main body (10). An air circulation cavity (11) is arranged at the air circulation main body (10). Sound-muffling holes (12) are arranged around the air circulation cavity (11). One end of the air circulation main body (10) close to an air inlet (15) is provided with a plurality of connection columns (13). A clearance hole (21) is arranged at the sound-muffling main body (20) for insertion of the connection column (13).
