The present invention relates to a vacuum cleaner, and more particularly, to an extension tube control apparatus of a vacuum cleaner that allows a user to conveniently adjust the extension tube by adjusting the length of the extension tube through an adjustment knob installed on the upper part of the second extension tube.

In general, as shown in FIG. 1, the vacuum cleaner includes a main body 1 in which a suction motor (not shown) and a dust bag (not shown) are embedded and a power supply unit (not shown) for supplying power therein is disposed. In addition, the dust bag of the main body 1 guides the flow of air containing foreign substances such as dust, and a wire connected to the power supply is disposed inside, and a handle formed at the end of the connection part 4 connected to the wire. (3) is rotated by a driving motor (not shown) so that foreign matters such as dust are smoothly sucked through the suction hose 2 and the suction hose 2 connected to one end to scatter foreign matters such as dust. A brush (not shown) is disposed inside and the suction port 5 having the third lead connecting member 6 disposed at one end thereof, and air containing foreign matter such as dust sucked through the suction port 5 is sucked in. Flow of air to flow to the hose (2) side Guide and made of the extension pipe 100 is connected between the suction inlet (5) and the handle (3).

Here, the extension pipe 100 is connected to the third lead connecting member 6 of the suction port 5, the first extension pipe 200 for connecting the power, and the handle 3 is connected to the suction hose (2) The second extension pipe (300) connected to the connecting portion (4) of the), such that the foreign matter such as dust sucked through the first extension pipe 200 is moved to the suction hose (2) through the second extension pipe (300). Extension control unit 400 for adjusting the length of the first and second extension parts 200 and 300, an adjustment knob 490 for operating the extension control part 400, and the first and second extension parts 200 and 300. ) Consists of a power supply unit 500 for energizing the power even when the length adjustment is made between each other.

On the other hand, Figure 2 is an exploded perspective view of the extension tube of Figure 1, as can be seen with reference to the drawing, the first extension pipe 200 is a first body pipe 210 in close contact with the suction port and the first body pipe ( Screw 280 for fixing the antenna 230 of the fastening button 230, the power supply unit 500 is installed to be rotatably installed on the upper end of one side and elastically supported by the compression spring 220. And a first body pipe cover 290 coupled to the first body pipe 210 via a screw 281 so that the compression spring 220, the fastening button 230, and the screw 280 are not exposed to the outside. )

In addition, the second extension pipe 300 is the second body pipe 310 is inserted into the connection portion of the handle and the antenna 510 and the lead terminal of the power supply unit 500 accommodated in the second body pipe 310 The second body pipe cover 350 is coupled to the second body pipe 310 via the screw 360 so that most of the parts 540 are not exposed to the outside.

In addition, the extension adjusting part 400 is fitted to the inside of the first sealing member 410 and the second body pipe 310 installed to be coupled to the end of the first body pipe 210 and sealed. The extension pipe which is inserted into the first body pipe 210 and is fixed by the first body pipe cover 290 and has a plurality of tooth-shaped length adjusting grooves 423 formed along the length direction downward ( 420, a pipe fixing housing 430 fitted into the extension pipe 420 and seated into the second body pipe 310 to guide the extension pipe 420, and the pipe fixing housing 430. The second sealing member 440, which is inserted into the rear end of the) to prevent air from leaking into contact with the extension pipe 420, is inserted into the extension pipe 420, the extension pipe 420 is fixed to the pipe Housing 430 and second sealing member 440 The separation prevention ring 450 is prevented from falling out, the C-shaped spring 460 seated on the middle portion of the outer peripheral surface of the pipe fixing housing 430, the C-shaped spring 460 is in close contact with the pipe fixing housing 430 It consists of a roller seating member 470 and a cylindrical roller 480 seated and positioned by the roller seating member 470.

In addition, the adjusting knob 490 is operated back and forth to be hooked to the roller seating member 470 to be fitted to the lower end of the second body pipe 310 so as to stretch the length of the extension pipe 420 (hook) ( 491 is formed.

In addition, the power supply unit 500 is a multi-stage antenna 510 which is fixed to the first body pipe 210 so that one end is in close contact with the screw 280 and is flexible and energized. In addition to being fixed to the other end of the antenna 510, the front end is composed of a lead terminal 540 is inserted into the connection portion of the handle.

The vacuum cleaner according to the related art configured as described above, when the user applies power to the main body 1 and turns on the power switch through the handle 3, the suction motor installed in the main body 1 is provided. It rotates at a high speed to generate a strong suction force, and foreign matters such as dust on the cleaning part are introduced into the main body 1 through the suction port 5, the extension pipe 100, and the suction hose 2 by the suction force. The dust is collected in the dust bag installed in the main body 1 and is cleaned.

On the other hand, when the cleaning part is far from the user or at a short distance, when the user manipulates the adjustment knob 490 before or after, the cylindrical roller 480 seated on the roller seating member 470 of the extension adjusting unit 400 is extended. It is removed from the length adjusting groove 423 of the pipe 420.

Accordingly, when the user applies a force in a direction in which the second body pipe 310 of the second extension pipe 300 stretches relative to the first body pipe 210 of the first extension pipe 200, the extension control unit 400. The extension pipe 420 of the slide out of the second body pipe 310 or enters.

Next, if the user does not operate the front or rear of the control knob 490 in the desired length, the cylindrical roller 480 seated on the roller seating member 470 of the extension adjusting unit 400 is C-shaped spring ( It is fixed to the length adjusting groove 423 of the extension pipe 420 by the tensile force of 460.

Accordingly, the first body pipe 210 of the first extension pipe 200 and the second body pipe 310 of the second extension pipe 300 are fixed so that the extension pipe 100 may be operated in accordance with the user's operation according to a long distance or a short distance. The length is stretched.

However, when the vacuum cleaner according to the related art is intended to adjust the length of the extension tube during cleaning, it is necessary to operate an adjustment knob installed on the lower side of the second extension tube so that the waist is bent to adjust the length of the extension tube or extend the extension tube with both hands. There was an uncomfortable problem in use, such as holding and adjusting the length.

Therefore, the present invention is devised to solve the above problems, by installing the control knob on the upper part of the second extension tube of the extension tube to operate the extension control through the connecting member, the user can conveniently adjust the length of the extension tube It is an object of the present invention to provide an extension tube control device for a vacuum cleaner.

The vacuum tube extension device according to the present invention for achieving the above object, the vacuum cleaner by sucking the foreign matter such as dust through the extension tube consisting of the first extension tube and the second extension tube by the suction force generated by the driving of the suction motor. In the vacuum cleaner to collect the dust bag in the main body, characterized in that the control knob is installed on the handle side of the second extension pipe, and is configured to adjust the length of the extension tube by connecting the adjustment knob with the extension control unit through a connecting member. It is done.
