Abstract

The present invention discloses a muffler device (4) for vacuum cleaner, which is arranged in an air exhaust passage (3) extending from a motor (1) of the vacuum cleaner to an air exhaust outlet (2), and is provided with a plurality of elongate tubes (5). A vacuum device (4) with a muffler device according to the invention can reduce noise produced by the vacuum cleaner during operation, by improving the flexure quality of the air exhaust passage (3) to cause energy loss of sound waves during diffusing.
