[0002] The suspension blower is a new type of blower, which uses a suspension bearing at its core, has high efficiency and large air volume. In order to ensure low noise during the air supply process, a silencer is installed inside. The main structure of the existing silencer includes a silencer body and a silencer pipe fixed inside the silencer body. The silencer pipe is fixed and single-layered, which not only has poor silencing effect, but also cannot be adjusted according to suspension blowers of different powers and configurations. Blowers of different specifications and powers also use silencer pipes of the same specifications, which affects the silencing effect.
