Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a transmission device for a power brush and a corner brush in a nozzle device of a cleaner for sucking dust.

[0002]

[Prior Art]

 As shown in FIG. 3, a nozzle device of a conventional vacuum cleaner has a power brush 33 rotatably attached to the nozzle device 1 by providing a protrusion 39 in a cylindrical spiral shape, and a motor 34 driven by an electric current from the main body. And a belt 35 for transmitting the output of the motor 34 to the power brush 33 via a pulley 36 provided on the output shaft of the motor 34, and rotatably attached to both front side surfaces of the nozzle device 1. The cylindrical hollow base 37 is provided with corner brushes 32a and 32b in which brushes 38 are implanted.

In cleaning the floor surface of the nozzle device 1 having such a configuration, the power brush 33 is rotated by the output of the motor 34 to knock out dust to the center of the nozzle suction port for cleaning.

Further, when cleaning the corners of a room, etc., the corner brushes 32a, 32b are rotated by the outer sides of the corner brushes 32a, 32b contacting walls to collect dust.

[0005]

[Problems to be solved by the device]

 In the nozzle device of such a vacuum cleaner, the corner brushes 32a and 32b are only rotatably attached and do not rotate unless force is applied from the outside. Therefore, dust cannot be collected outside the corner of the room.

Therefore, it has been necessary to make it easier to suck dust that is located away from the nozzle portion.

[0007]

[Means for Solving the Problems]

 In order to solve such a problem, the present invention provides a nozzle device for a cleaner including a nozzle device main body, a plurality of corner brushes, a power brush, and a drive motor for rotating the power brush. It is equipped with a transmission mechanism that transmits the output of the to the multiple corner brushes and the power brush. The transmission mechanism may use a shaft or pulley and a belt to transmit the output of the driving motor to the plurality of corner brushes.

[0008]

[Action]

 The corner brush works in conjunction with the drive motor for rotating the power brush to rotate the corner brush, so that dust under the bristles apart from the nozzle suction port can also be lifted and sucked.

【Example】

 An embodiment according to the present invention will be described with reference to FIGS. Further, the same components as those of the conventional technique are designated by the same reference numerals, and the description thereof will be omitted. FIG. 1 shows a first embodiment according to the present invention. A first pulley 36 is attached to the output shaft of the drive motor 34 in the same manner as in the prior art, but in the present embodiment, a second pulley is further provided on both sides of this pulley 36. 2 and a worm 3a are coaxially attached. Further, as in the prior art, the one end portion 33a of the power brush 33 and the drive motor 34 are linked by the pulley 36 and the belt 35.

A worm wheel 4a that meshes with the worm 3a is rotatably attached to the nozzle device 1. Further, a pulley 6a is attached coaxially with the worm wheel 4a. Further, a pulley 7a is coaxially fixed on the base 37a of the corner brush 32a and is interlocked with the pulley 6a via a belt 8a.

Further, a shaft 9 is rotatably supported by the nozzle device 1 in parallel with the power brush 33, and pulleys 10 and 11 are fixed to both ends of the shaft 9. The pulley 10 is connected to the pulley 2 by the belt 12, and the pulley 11 is connected to the worm 3b via the belt 13.

The other corner brush 32b of the nozzle device 1 is connected in the same manner as the corner brush 32a side by the worm 3b, the worm wheel 4b, the pulley 6b, the belt 8b and the pulley 7b. Has been done.

When cleaning is started in the nozzle device having such a configuration, the drive motor 34 is rotated by the electric current supplied from the main body, and this rotational force is applied to the power brush 33 and the shaft 9 by the belts 12 and 35, respectively. Transmitted. The rotational force whose direction is changed by the worm 3a and the worm wheel 4a rotates the corner brush 32a via the pulleys 6a and 7a.

Further, the rotational force transmitted by the shaft 9, the worm 3b, the worm wheel 4b, the pulley 6b, the belt 8b, and the pulley 7b rotates the corner brush 32b.

With such a configuration, it is possible to drive the power brush 33 and the corner brushes 32a and 32b with one drive motor 34. FIG. 2 shows a second embodiment of the nozzle device according to the present invention.

In this embodiment, the transmission of the rotating force from the drive motor 34 to the power brush 33 and the corner brush 32a has the same configuration as that of the first embodiment.

However, as the rotational force transmission means to the corner brush 32b, the pulley 14 is provided coaxially with the pulley 6a, and the pulley 15 is provided on the side of the corner brush 32b. Belts 15 are connected to each other. Further, a pulley 17 is provided coaxially with the pulley 15, and is connected to a pulley 19 coaxially fixed with the corner brush 32b by a belt 18.

According to the present embodiment, the output of the drive motor 34 can be transmitted to the corner brush 32b via the belt 16.

As the rotation transmitting means, other than the above embodiment, a chain, a combination of a V belt and a pulley, or the like may be used.

[0020]

[Effect of the device]

 According to the proposed nozzle device, a single drive motor can drive the power brush and the corner brushes attached to both ends of the nozzle device. Therefore, the nozzle device with a simple configuration and high dust collecting capability can be used. Can be obtained.
