Referring to FIGS. 11 to 14, the process by which air is efficiently supplied to the first prototype C1 will be described.

When the air sucked from the suction head 17 passes through the first cyclone separator and is sucked into the second cyclone separator, the air F1 may rotate above the plurality of airflow forming members 220.

The air (F1) rotating on the upper side of the airflow forming member 220 may flow into the inlet 201 of the cyclone cone 210. At this time, the air F1 flowing into the inlet 201 comes into contact with the airflow forming wing 226 of the airflow forming member 220 located inside the cyclone cone 210.

The airflow forming wing 226 protrudes from the outside of the exhaust pipe 222 of the airflow forming member 220 and extends spirally along the circumference of the exhaust pipe 222 in the longitudinal direction of the exhaust pipe 222 to form a rotating airflow. , the air (F1) flowing into the inlet 201 may also rotate in the same spiral direction. Accordingly, a rotating airflow F2 may be generated inside the cyclone cone 210.

Fine dust in the air introduced by the rotating airflow (F2) generated inside the cyclone cone (210) receives centrifugal force, and through this, can be finally discharged through the dust outlet (202).

As the rotating airflow (F2) is generated inside the cyclone cone 210, an airflow (F3) rotating in the same direction as the rotating airflow (F2) inside the cyclone cone 210 may be formed on the upper side of the airflow forming member 220. there is.

The airflow F3 formed on the upper side of the airflow forming member 220 is spaced apart from the airflow forming members 220 that are not connected to each other by the connecting ribs 225 among the airflow forming members 220 forming the second circular shape (C2). It is possible to form an airflow toward the space provided.

The airflow formed in the direction toward the spaced space may gather in the spaced space to form an airflow F4 that ultimately flows toward the airflow forming member 220 forming the first circular shape C1. Accordingly, air containing fine dust can be smoothly supplied to the airflow forming member 220 forming the first circular shape C1, thereby performing a dust removal function.

As air is smoothly supplied to the first circular shape (C1), the flow can be optimized, and as a result, the pressure loss in the cyclone dust collector (10) can be reduced.

The number and arrangement of the airflow forming members 220 and cyclone cones 210 constituting the secondary cyclone separator 200 described above with reference to FIGS. 2 to 15 are only examples, and the wireless to which the cyclone dust collector 10 is applied It is natural that depending on the vacuum cleaner 1, the air flow forming members 220 and cyclone cones 210 constituting the secondary cyclone separator 200 may be arranged in various numbers and in various shapes.
