<p>This invention provides a silencer for a vacuum cleaner. The silencer for the vacuum cleaner comprises at least one hermetic expansion chamber (1) mounted in an exhaust channel of the vacuum cleaner and allowing an exhaust airflow from the vacuum cleaner to pass through. The expansion chamber (1) at its two sides has an inlet (2) and an outlet (3) connected to the exhaust channel. A silencing board (4) is mounted in the expansion chamber (1), separating the inlet (2) from the outlet (3). Pores (5) are distributed throughout in the silencing board (4). The silencer integrates several different silencing structures together, and, when mounted to the exhaust port of the vacuum cleaner, can considerably diminish the noise generated by the vacuum cleaner in operation. <IMAGE></p> |
