In addition, the blower fan 60 is wrapped around the outside so as to open in the front and extends toward the front of the inlet port 53, and installs the guide passage 70 to open toward the bottom.

In addition, the outlet port 80 is formed to be opened in the transverse direction in front of the inlet port 53 corresponding to the outlet opening to the lower portion of the guide passage 70.

Another embodiment of the dust scattering apparatus of the present invention configured as described above will be described with reference to FIG. 6.

First, as shown in FIG. 6A, a blower force is applied to one side of the brush 54 at the time of advancing the suction body 50 and the blower force 61 is not applied to the rear of the brush body 50. On the other side, a second blowing fan 62 is mounted on the other side of the suction body 50 when the blowing force acts backward and the blowing force does not act on the front side, and the 1.2 blowing fans 61 and 62 are moved forward. The first guide passage (71) and the second guide passage (72) are installed bilaterally so as to be extended in the outer direction of the inlet (53) to extend in the front and rear of the suction port (53) and open in both directions toward the lower side.

It is discharged to the outside through the discharge port 80 through the position. The air discharged through this process causes the dust and foreign matters scattered on the floor to be blown away, especially foreign matters caught between the carpets. The dust or foreign matter thus scattered is sucked through the suction port 53 together with the dust and foreign matter guided by the brush 54.

In addition, when the suction body 53 moves backward, the sensor 56 detects the traveling direction to drive the motor 55 in the reverse direction, and at the same time, the brush 54 connected to the motor 55 rotates clockwise. While scraping dust and foreign matter scattered on the floor guides to the inside of the suction port (53). At this time, the blowing fan 60 is rotated in the same direction as the brush 54 by the power of the motor 55, but the blowing force is not generated by the structural characteristics of the blowing fan 60.

Meanwhile, in the case of FIG. 6A, when the suction body 50 moves forward, a blowing force acts on the first blowing fan 61 to be guided to the first guide passage 71 and discharged through the outlet 81. When the suction body 50 is reversed, the blowing force generated rearward from the second blowing fan 62 passes through the second guide passageway 72. It is discharged to the outside through the discharge port 82 to perform the dust scattering function as when moving forward.

6B and 6C perform a function of dispersing dust only when advancing through a process similar to the embodiment of FIG. 6A.
