A vacuum cleaner is a commonly used cleaning device in homes or public places. Its working principle is to use a motor to generate negative air pressure in a sealed casing, and under the action of this pressure difference, it can suck in dusty air. After vacuuming, the dust in the dust cup needs to be cleaned. However, the current cleaning of the dust cup requires the removal of the entire casing of the dust cup, and the disassembly and assembly of the dust cup casing is relatively complicated, which makes the cleaning efficiency very low.

The core component of the vacuum cleaner is a dust-gas separation device, whose function is to isolate and concentrate dust or debris in the air.

The dust and gas separation device is equipped with a filter screen tube. The existing filter screen tube has the following defects: because the mesh on the filter screen tube is small, it is easy to be clogged by dust, so it needs to be cleaned frequently, which is more cumbersome; if it is not carried out in time After cleaning, the dust will block the mesh, which will greatly reduce the dust removal efficiency of the filter cartridge; in severe cases, it will also cause resistance to the airflow, resulting in poor airflow and even damage to the vacuum cleaner motor.

When the dust-gas separation device of the existing vacuum cleaner adopts centrifugal separation, centrifugal spiral separation is mostly used.
