FIG. 5 is a cross-sectional view taken along the line II ′ of FIG. 3, and FIG. 6 is a cross-sectional view illustrating an internal operation of the nozzle according to the first embodiment of the present invention.

5 and 6, the suction nozzle 20 according to the first embodiment of the present invention includes an agitator 240 rotatably coupled to the nozzle body 200, and the agitator 240. An agitator cover 249 shielding an upper side, a guide rib 280 extending downward from an inner side surface of the agitator cover 240 and guiding air flow in the nozzle and one side of the guide rib 280 A first guide 270 extending from the inner surface of the agitator cover 249 from is included.

In detail, the agitator 240 includes a wing portion 240a that separates the foreign matter while contacting the surface to be cleaned. The agitator 240 may be coupled to the agitator fixing part 241 and rotated in a predetermined direction.

The guide rib 280 allows the rotational flow generated during the rotation of the agitator 240 to be easily performed.

Most of the air sucked from the air inlet 245 is moved toward the connecting pipe 225, but some air is rotated inside the nozzle along the rotated agitator 240.

At this time, the guide rib 280 is located on one side of the first guide 270 so that air can be easily rotated along the first guide 270 or the agitator cover 249.

If the guide rib 280 is not provided, the sucked air may not be rotated along the agitator 240 but may hover or accumulate at an inner point of the agitator cover 249. .

In particular, this phenomenon may further occur at the position of the guide rib 280 shown in FIG. 5.

By providing the guide rib 280, the air can be easily rotated along the inner surface of the agitator cover 249 without hovering in one position.

Meanwhile, the first guide 270 is spaced apart from the inner surface of the agitator cover 249 by a predetermined distance. The first guide 270 may extend in a shape corresponding to an inner surface of the agitator cover 249.

In addition, a through hole 271 is formed in the first guide 270 to move air rotating along the agitator 240. The through holes 271 may be spaced apart from each other by a predetermined distance.

Between the agitator cover 249 and the first guide 270, an auxiliary flow path 274 through which air moves is formed. Air introduced into the auxiliary flow path 274 through the through hole 271 may be moved toward the connection pipe 225.

Under the suction nozzle 20, a main flow path 226 is formed through which most of the air sucked through the air suction part 245 is moved. The main flow path 226 extends from one side of the agitator 240 toward the rear (right direction in FIG. 5).

In addition, the suction nozzle 20 has a lamination flow path 250 in which air moved through the main flow path 226 and the auxiliary flow path 274 are formed. The lamination passage 250 is formed at one side of the connection pipe 225.

Referring to Fig. 6, the air flow according to the present embodiment will be described.

Most of the air sucked through the air suction unit 245 is moved to the connection pipe 225 via the main flow path 226 and the lamination flow path 250.

In addition, some of the sucked air is guided by the guide rib 280 and is moved along the inner surface of the agitator cover 249. In addition, the moved air flows into the auxiliary flow path 274 through the through hole 271.

Here, the air can pass through the through hole 271 because the suction force of the body acts toward the rear.

The air moved along the auxiliary flow path 274 merges with the main flow path 226 in the lamination flow path 250 and then moves toward the connection pipe 225.

As described above, since air that rotates inside the suction nozzle 20 may be moved to the lamination passage 250 through the auxiliary passage 274, the suction performance of the foreign material may be improved. . Therefore, there is an effect that it is possible to reduce the amount of foreign matter rotating in the nozzle 20.

The second embodiment will be described below. Since the present embodiment differs only in the structure of the guide ribs, only the differences are explained and the same reference numerals are used for the same parts.
