Vacuum cleaners are very common electrical appliances on the market. Through set up vacuum motor in vacuum cleaner, will carry with the dirty air suction of dirt inside the dust catcher, through the separation back, the dirt persists in vacuum cleaner the inside, and the clean air after the filtration is discharged to the external world.
In the prior art, in order to separate dust, a bag type separator or a cyclone separator is generally arranged inside a vacuum cleaner.
In the case of the bag-type separator, the main structure of the bag-type separator is a dust bag with filtering capability installed inside the dust collector, and the bag is provided with small holes for filtering out the particulate matters (dust and dirt) carried in the airflow passing through the dust bag. However, after a period of use, the small holes on the dust bag can be rapidly blocked by dirt, so that the suction force of the dust collector is reduced; after the dust collecting bag is filled, the old bag needs to be thrown away and replaced by a new bag, so that resource waste and environmental pollution are caused, and the use cost of a user is increased; the dirt separation efficiency is low. For the cyclone separator, the airflow carrying dust can form cyclone inside the dust collector, and the dust particles have relatively large mass and can be in friction collision with the wall of the container and fall into the dust collecting box under the action of centrifugal force, so that the aim of separating the dust and air is fulfilled. However, the cyclone separator consumes a large vacuum pressure, requires a large vacuum motor power, and has a strong noise ratio during operation, which affects user experience.
The prior art provides a dust and dirt separator comprising a foraminous disc at the air flow outlet of the collecting chamber and a motor for rotating the disc. The disk is arranged to rotate about an axis of rotation and includes apertures through which a cleaned airflow passes. The dirt-laden air stream enters the chamber and contacts the rotating turntable, which applies a tangential force to the air stream so that dirt entrained in the air stream moves radially along the surface of the turntable towards the edge of the turntable. During this process, the air flow will exit through the small holes in the turntable, and the dirt therein will continue to move towards the outer radial edge and collect at the bottom of the chamber due to its greater inertia. Compared with a cyclone separator, the separator consumes less vacuum pressure and can be matched with a vacuum motor with less power and noise.
However, in operation of such separators, the dirt-laden air stream impinges directly on the discs. The large mass particles in the dirt will cause damage to the turntable and affect the balancing movement of the turntable.
