[0002] Vacuum cleaners can be divided into vertical, horizontal and portable types according to their structure. The working principle of a vacuum cleaner is to use an electric motor to drive the blades to rotate at high speed, generate negative air pressure in a sealed shell, and absorb dust.

[0003] At present, a large part of the noise of the vacuum cleaner comes from the air duct. The airflow has a lot of wind resistance and wind noise when passing through a short air duct, which makes the user have a bad experience when using it. Now the way to reduce the noise in the air duct is to lay sound-absorbing cotton in the air duct, but the noise reduction effect is general. Summary of the invention
