In addition, at a predetermined position of the main body 1, a flow of air is guided so that the dust is sucked by the dust collecting pack in the main body 1, and the electric power supplied to the suction hose 2 One end is connected.

At the other end of the suction hose (2), a handle member (3) equipped with a connection portion (4) connected to a wire is connected.

The other end of the connecting portion 4 of the pull member 3 connected to the suction hose 2 and the suction member 5 suck air containing dust by the suction hose 2 when cleaning the room, A first extension device 110 and a second extension device 120 which are connected to the wire of the suction hose 2 and are capable of supplying power while varying the length of the antenna, Respectively.

The suction ball 5 is connected to a power brush (not shown) which is rotated by a driving motor to scatter dust, so that the third lead wire 6 is disposed at one end and the dust in the room can be sucked smoothly through the suction hose Is disposed inside.

The first extension device 110 includes an extension pipe 111 constituting a keyhole pipe and a recessed portion 111b formed on the upper portion of the cylindrical dust inlet 111a of the extension pipe 111. The recessed portion 111b A first lead wire 113 fixed to one side of the fixing portion 112 so as to be inserted and connected to the connection portion 4 of the pull member 3, A pair of first antenna wire rods 114 fixed to the fixed portion 112 to be connected to the first lead wire 113 so as to be parallel to the central axis of the extension tube 111, And a length adjusting device 115 provided inside the extension pipe 111. [

The second extension device 120 includes a connection pipe 121 fitted to the dust suction port 111a of the extension pipe 111 and having a protrusion 121a fitted in the recess 111b, The first antenna wire 114 is accommodated in the protruding portion 121a of the first antenna wire 121 in a longitudinal direction and the third antenna wire 118 is adjustably inserted, And a length adjusting groove 123 formed at a predetermined depth and spacing below the outer circumferential surface of the connecting pipe 121 and adapted to be seated by a leaf spring 115g of the length adjusting device 115 have.

Next, the operation and effect of the vacuum cleaner according to the present invention will be described.

First, when a user applies power to the main body 1 in order to clean the room, power is supplied to the power supply unit built in the main body 1 so that the suction motor for generating a suction force can be driven. The electric power is sequentially transmitted from the power supply unit to the knob member 3 and the first extension device 110 and the second extension device 120 by the electric wire disposed in the suction hose 2 .

Since the first lead wire 113 is connected to the connecting portion 4 of the pull member 3 at this time, the first and second antennas 110 and 120, which are installed across the first and second extension devices 110 and 120, The power can be transmitted to the suction ball 5 by the connection of the wire rods 114 and 122.

That is, since the third lead wire 6 connected to the end of the second antenna wire 122 is disposed in the suction ball 5, the third lead wire 6 is electrically connected to the third lead wire 6 by electric wires The power brush disposed in the suction ball 5 is rotated while the driving motor is driven, thereby scattering dust and foreign matter on the indoor surface.

According to the above description, dust and foreign matter on the indoor surface are scattered by the power brush, so that air containing dust and foreign matter is sucked by the suction force of the suction motor built in the main body 1, .

When the cleaning part is far or short in cleaning the room, the extension device 100 between the pull member 3 and the suction member 5 is connected to the first extension device 110 through the second extension device 120), remove it, and move it to the proper length according to the distance of the cleaning area, and perform cleaning.

At this time, the first and second antenna wire rods 114 and 122 disposed on the first and second extension devices 110 and 120 are connected to each other by the leaf spring 115g of the length adjusting device 115, So that the power can be transmitted to the driving motor that rotates the power brush so that the power brush disposed in the suction ball 5 can be rotated.

Therefore, the distance between the pull tab 3 and the suction member 5 can be varied by the first and second extension devices at all times regardless of whether the user needs to clean the room in a short distance or a long distance from the user So that the user can more easily perform the cleaning function.

As described above, according to the cleaner according to the present invention, it is possible to easily perform the cleaning function irrespective of whether the user is away from the clean room or not at a remote place, There is a practical effect.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of the invention.
