Description

[0001] technical field

[0002] The invention relates to a vacuum cleaner, in particular to a silent vacuum cleaner. Background technique

[0003] Generally, a vacuum cleaner includes a motor assembly having a motor air inlet and a motor air outlet. The motor assembly is used to generate a vacuum source, and the vacuum suction sucks impurities on the ground and surrounding air from the air inlet of the vacuum cleaner into the dust collection bag, and then the air enters the motor air inlet of the motor assembly from the dust collection bag, and passes through the motor outlet. The air outlet is discharged from the air outlet of the vacuum cleaner. During the working process of the vacuum cleaner, noise will be generated during the rotation of the motor and the flow of airflow in the vacuum cleaner. In addition, the motor components in the prior art are all placed horizontally, the air inlet of the motor is aligned with the dust bag of the vacuum cleaner, the air outlet of ...
