A pair of

swing roller

221 and 222 can be rotatably set in the dirt suction inlet 202 of ozzle main body 201.The relative mantle friction that will be cleaned of a pair of swing roller 221 with 222, and make must be cleaned lip-deep such as the people hair or/and the thin dirt of the hair of animal be concentrated into piece and be drawn in the dirt suction inlet 202.Therefore, this a pair of

swing roller

221 and 222 can be arranged on the centre of dirt suction inlet 202, thereby maximum suction can be applied between a pair of

swing roller

221 and 222.

This all comprises

limit rotation part

231 and 232, cylinder body and removing part in

swing roller

221 and 222 each.

Limit rotation part

231 and 232, cylinder body and to remove part similar with limit rotation part 29, cylinder body 50 and removing part 60 according to the swing roller 20 of the foregoing description; Therefore, its detailed description is omitted.

Yet, thereby being configured when one 221 in a pair of

swing roller

221 and 222 and 222 rotations according to the

limit rotation part

231 and 232 of the suction nozzle assembly 200 of this embodiment, another swing roller 222 and 22 1 stops.

Limit rotation part

231 and 232 structure are shown in Figure 13 A and 13B.

swing roller

221 and 222, and make second swing roller 222 along clockwise direction (with reference to the arrow I among Figure 13 A) rotate, but can not rotate in the counterclockwise direction.

Therefore, if the first and second

limit rotation parts

231 and 232 constitute the ratchet part shown in Figure 13 A and 13B, first ratchet 233 of first swing roller 221 is arranged to rotation in the counterclockwise direction, but does not rotate along clockwise direction.And, be arranged to rotation along clockwise direction with second swing roller, 222 co-axially fixed second ratchets 237, but do not rotate in the counterclockwise direction.

Below, the operation of the suction nozzle assembly that is used for vacuum cleaner 200 with said structure is described with reference to Figure 12,13A and 13B.

When the arrow J shown in user such as Figure 13 B pushes away suction nozzle assembly 200 forward, first and second swing rollers 221 with 222 owing to rotate in the counterclockwise direction relative to the frictional force on the surface that will be cleaned trend.The first limit rotation part 231 makes (referring to the arrow K) rotation in the counterclockwise direction of first swing roller 221, thereby when suction nozzle assembly 200 moved forward, first swing roller 221 rotated in the counterclockwise direction.Yet the second limit rotation part 232 stops second swing roller 222 to rotate along clockwise direction, thereby when suction nozzle assembly 200 moved forward, second swing roller 222 kept inactive state.

When second swing roller 222 keeps inactive states when the user pushes away suction nozzle assembly 200 forward as arrow J, be formed on mantle friction that a plurality of projections 242 on the excircle of second swing roller 222 will be cleaned relatively so that thin dirt is concentrated into piece.At this moment, first swing roller 221 is along rotating in the counterclockwise direction as arrow K, and second swing roller 222 by dirt suction inlet 202 inside upwards pushes away the dirt that is concentrated into piece thus.Therefore, suction nozzle assembly 200 can suck thin dirt effectively.

On the other hand, Figure 13 A shows each the cylinder place first and second limit rotation part 231 that is arranged on a pair of

swing roller

221 and 222 when the user pulls back the suction nozzle assembly 200 that is used for vacuum cleaner and 232 operation.

When the user pulls back suction nozzle assembly 200 as shown by arrow H, first and second swing rollers 221 with 222 owing to the frictional force relative to the surface that will be cleaned tends to rotate along clockwise direction (referring to arrow I).The first limit rotation part 231 stops first swing roller 221 to rotate along clockwise direction, thereby when suction nozzle assembly 200 was mobile backward, first swing roller 221 kept inactive state.Yet the second limit rotation part 232 can make second swing roller 222 rotate along clockwise direction, thereby when suction nozzle assembly 200 was mobile backward, second swing roller 222 rotated along clockwise direction.

Therefore, since first swing roller 221 when the user pulls back suction nozzle assembly 200 as shown by arrow H keeps inactive states, be formed on mantle friction that a plurality of projections 241 on the excircle of first swing roller 221 will be cleaned relatively so that thin dirt is concentrated into piece.At this moment, second swing roller 222 turns clockwise as shown by arrow I, and first swing roller 221 by dirt suction inlet 202 inside upwards pushes away the dirt that is concentrated into piece thus.

If suction nozzle assembly 200 is provided with a pair of

swing roller

221 and 222 as this embodiment, in the

swing roller

221 and 222 one make dirt concentrate and

swing roller

221 and 222 in another dirt of concentrating is upwards pushed in the dirt suction inlet 202.Therefore, the suction nozzle assembly 200 with a pair of

swing roller

221 and 222 can more effectively suck thin dirt than the suction nozzle assembly 1 with aforesaid swing roller 20 from the surface that will be cleaned.

Figure 14 is the schematic diagram that schematically shows the suction nozzle assembly 200 with rotation limited part different with the suction nozzle assembly with a pair of

swing roller
