る。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. As shown in the drawing, the suction tool 1 is configured by connecting an upper suction tool 3 and a lower suction tool 4 via a bumper 2, and forms a suction chamber 6 having a lower opening as a suction port 5 in front of the upper suction tool 3 and the lower suction tool 4. . A rotor 7 is rotatably provided in the suction chamber 6 and a brush is provided. A motor 8 serving as a driving source of the rotor 7 applies a rotational force to a gear 10 provided at one end of the rotor 7 via a belt 9. And the rotor 7 is rotated. A pair of rollers 11 is provided near the suction port 5, and a driving wheel 12, which is rotatably and integrally attached to the rotor 7, is pressed against a concave peripheral surface 13 formed on the roller 11 to rotate the rotor 7. Has been communicated to. And concave surface 1
One or both of the contact surfaces of the drive wheel 3 and the drive wheel 12 are formed of an elastic material. Further, the roller 11 is configured such that the outer peripheral surface protrudes toward the floor surface side from the lower suction tool 4. 14
Is a bearing A for holding a rotating shaft 15 of the roller 11, which is made of an elastic material and urges the roller 11 toward the drive wheel 12. Reference numeral 16 denotes a bearing B that holds the rotor 7. The operation and operation of this embodiment will be described. By rotating the rotor 7 by the motor 8 when cleaning the carpet, the roller 11 is simultaneously rotated through a pair of drive wheels 12 provided near the suction port 5 and integrally provided with the rotor 7. . Since the roller 11 protrudes toward the carpet from the lower surface of the suction tool 4, it provides a propulsive force to advance the suction tool 1 by the rotational force of the roller 11, so that the suction tool 1 can be lightly operated even on the carpet. . Also,
Even if a load is applied to the roller 11 due to the resistance of the carpet, the load is not directly applied to the motor 8, so that the durability of the motor 8 is also improved. In addition, the rotation of the rotor 7 is transmitted to the roller 11 by pressing the drive wheel 12 and the concave peripheral surface 13 formed on the roller 11 so that the rotation of the roller 11 is prevented from being damaged without damaging the outer peripheral surface of the roller 11 that contacts the floor. Can be transmitted. Further, the rotation speed of the roller 11 can be arbitrarily set by changing the outer diameter of the concave peripheral surface 13.

機の吸込具を提供できる。As is apparent from the above embodiments, according to the present invention, the driving wheel is provided integrally with the rotor, and the rotation of the rotor is transmitted to the roller via the driving wheel, thereby rotating the rotor. Since the roller rotates at the same time as the rotation of the driving motor, the carpet can be cleaned lightly, and since the second motor for driving the roller is not required, the size of the suction tool can be reduced, so cleaning The work is easy to clean and easy to turn. Further, since the rollers are not directly driven by the motor, the load applied to the rollers is not applied to the motor, so that the durability of the motor is improved. In addition, since the rotation of the rotor is transmitted to the roller by pressing the drive wheel and the concave peripheral surface formed on the roller, the rotation can be transmitted without damaging the outer peripheral surface of the roller that comes into contact with the floor surface. In addition, it is possible to provide a suction device for a vacuum cleaner in which the number of rotations of the roller can be arbitrarily set by changing the outer diameter of the concave peripheral surface.
