Description

Suction tube of vacuum cleaner {INHALATION PIPE OF VACUUM CLEANER}

The present invention relates to a suction tube of a vacuum cleaner, and more particularly, it is possible to adjust the length of the suction tube, which is coupled to the vacuum cleaner to suck dust and the like into the vacuum cleaner.

Normally, the vacuum cleaner uses a vacuum suction input to clean the dust by forcibly sucking dust and the like through the suction pipe. The suction pipe of the vacuum cleaner has a fixed length or is simply separated and coupled to the user. It was difficult to use easily adjusted to the desired length depending on the height or cleaning place and site.

In other words, the existing vacuum cleaner suction tube is composed of about 2 to 4 pipes in a separate coupling type to adjust the length, and the suction pipe of such a separate coupling structure cannot be used by finely adjusting the length in multiple stages. There was a disadvantage, and the inconvenience and the inability to move the cleaner compactly after use, due to the length and volume of the suction pipe.

In order to compensate for these shortcomings, a number of products have been preceded in order to adjust the length of the suction pipe arbitrarily with more convenient usability, but these are configured to be able to variably adjust the length of the suction pipe by operating the control lever. The operation of the suction pipe is controlled by the length of the operation is unstable, lack of ease of use according to the length adjustment operation, due to the protruding structure of the control lever was poor appearance.

Therefore, in the present invention, it is possible to easily adjust the length of the suction tube to any desired length in a relatively simple configuration to solve the problems and disadvantages of the suction tube of the existing vacuum cleaner to increase the usability of the vacuum cleaner and improve the product competitiveness as an improved appearance beauty In particular, the present invention is to provide a product of a clean appearance and at the same time to ensure the ease of use according to the length adjustment operation of the suction pipe by configuring the adjusting means in a compact structure.

The guide pipe 4 is coupled to the tip of the outpipe 3 coupled to the outer side of the inner pipe 2 connected to the vacuum cleaner, and the protrusion 4a is formed in the guide tube 4 so that the protrusion 4a is out. It is coupled to the guide request (2a) of the inner pipe (2) in the fitted state to the pipe (3), and the engaging projection (2b) formed on the side of the guide request (2a) is coupled to the guide request (2a) The protrusion 4a of the guide tube 4 is caught by the catching jaw 2b and at the same time, the outpipe 3 is arbitrarily removed from the inner pipe 2 by the protrusion 4a coupled to the guide request 2a. When the inner pipe 2 is pulled out and inserted from the outpipe 3 in a state where it is not rotated (a state where it is not turned), the slide is moved along the guide request 2a.

The inner pipe 2 is formed with a plurality of adjusting grooves 5, 5 'in a line, and the guide pipe 4 communicates with the adjusting grooves 5, 5' of the inner pipe 2 with a stopper 7 ) So that the lifting hole 10 can be lifted and the stopper 7 installed in the lifting hole 10 passes through the lifting hole 10 of the guide tube 4. Suction pipe by positioning the inner pipe (2) withdrawn and inserted from the outpipe (3) according to the selected position of the adjusting groove (5, 5 ') to which the stopper (7) is engaged. Allow the length of (1) to be adjusted.

In addition, the slider 6 is coupled to the outside of the guide tube 4, the lifting hole 10 is formed, the slider 6 is coupled to the cap (8, 8 ') on both sides and both cap (8, 8) ') The spring (11, 11') is installed elastically, the slider (6) inside the lifting hole 10 is located directly above the opening and closing portion (9) for opening and closing the lifting hole 10 is formed to form the opening and closing portion ( 9) interrupts the lifting operation of the stopper 7 located in the lifting hole 10 so that the stopper 7 can be caught and released from the adjusting grooves 5 and 5 'of the inner pipe 2.

In the above, the slider 6 and the caps 8 and 8 'on both sides are assembled with the male and female assembly pieces 12 and the assembling grooves 12a, so that the slider 6 and the caps 8 and 8' are opposite. The springs 11 and 11 'built in the caps 8 and 8' on both sides of the slider 6 are supported by the fixing pieces 13 inside the caps 8 and 8 'so that the springs 11, 11 ') is stably elastically coupled in the longitudinal direction to allow the guide tube 4 to be elastically supported on both sides.

5 is a cross-sectional view showing another embodiment of the present invention, Figure 6 is an enlarged cross-sectional view of the main portion excerpt of FIG.

As in the case of the above-described embodiment, the guide pipe 4 is coupled to one end of the out pipe 3 coupled to the outer pipe 2 connected to the vacuum cleaner to move the guide pipe 4 to move the out pipe 3. By moving from the inner pipe (2) it is possible to adjust the length of the suction pipe (1).

The guide pipe 4 is coupled to the out pipe 3 to form a lifting hole 10a through which the roller-type stopper 7a can be lifted and lowered from the adjusting grooves 5 and 5 'of the inner pipe 2 and both sides. Thus, the springs 14 and 14 'are elastically coupled to each other so that the slider 6a coupled to the outside of the guide tube 4 is movable in the longitudinal direction.

In addition, the inner side of the slider 6a is elastically supported by the springs 14 and 14 'and the stopper 7a moves up and down through the lifting hole 10a when the slider 6a is moved left and right. The stopper 7a is moved by the movement of the slider 6a by constituting the operating part 16 formed with both sides of the engaging grooves 15 and 15 ', which can be locked and detached from the adjusting grooves 5 and 5' of the pipe 2. ) Is inserted into and pulled out from the inner pipe 2 to the extension groove 5 and 5 'to adjust the length of the suction pipe 1.

Looking at it in more detail below;

The slider 6a is divided into an upper cover 61 and a lower cover 62 so as to be mutually separated from the outside of the guide tube 4, and the slider 6a of the upper cover 61 is operated by the operation unit 16. It is coupled to elastically supported by the springs 14, 14 'on both sides.

The slider 6a has recessed grooves 15 and 15 'formed on both sides of the bottom surface thereof, and the stopper 7a moves up and down through the lifting hole 10a from the adjusting grooves 5 and 5' of the inner pipe 2. The locking and disengagement is performed, and the caps 8 and 8 'are respectively coupled to both sides of the slider 6a as in the above-described embodiment.

Reference numeral 17 in the drawings shows a packing pipe.

According to the present invention configured as described above, when the slider 6 is slid in the longitudinal direction, the opening / closing portion 9 inside the slider 6 opens and closes the lifting hole 10 so that the inner pipe 2 is outpipe 3. When the stopper 7, which is in the locked state in the locking grooves 5 and 5 'of the inner pipe 2 when being pulled out and inserted from the inner pipe 2, moves in the drawing and insertion movement of the inner pipe 2, 5 ') ascends through the lifting hole 10 and releases the slider 6 which is moved to either side, and the slider 6 is elastically coupled with both caps 8 and 8'. 11, 11 ') returning to its original position by the restoring force of the slider 6, the opening and closing portion 9 of the slider 6 closes the lifting hole 10, the stopper 7 built in the lifting hole 10 is the inner pipe (2) By pulling out the inner pipe 2 from the out pipe 3 by sticking to the fixed position of the locking groove 5, 5 'on either side of the Insertion is to adjust the length of the suction pipe (1) arbitrarily, looking at the operation of the present invention in detail as follows.

When the slider 6 is slid to one side, the caps 8 and 8 'coupled to both sides of the slider 6 move together in the moving direction of the slider 6, and both sides are moved by the movement of the slider 6. The springs 11, 11 'inside the caps 8, 8' formed on the side (opposite the moving direction of the slider 6) are compressed toward the guide tube 4 fixed to the outpipe 3.

In the state where the slider 6 is moved to one side as described above, the slider 6 compresses one of the springs 11 and 11 'and at the same time, the opening and closing portion 9 of the slider 6 moves to the guide tube ( The lifting hole 10 of 4) is opened.

Accordingly, when the inner pipe 2 is pulled out (reduced in length) or inserted (extended in length) from the out pipe 3, the stopper 7 that is caught in the adjusting grooves 5 and 5 'is moved by the inner pipe 2. By overcoming the locking load of the adjustment groove (5, 5 ') is to rise through the lifting hole (10).

That is, the stopper 7 held in the adjusting grooves 5 and 5 'moves the inner pipe 2 due to the release (opening) of the opening and closing portion 9 of the slider 6 blocking the lifting hole 10. It rises while leaving the adjusting groove (5, 5 ') by the force to the outer circumferential surface of the inner pipe (2) is completely positioned on the outer circumferential surface of the inner pipe (2), and the other side of the adjusting groove (5, 5') The length adjustment is repeated while passing through), and when the user releases the slider 6 while drawing or inserting the inner pipe 2 to an appropriate length, the spring 11, 11 'which has been compressed in one direction is removed. As the slider 6 returns to its original position by the restoring force, the opening / closing portion 9 of the slider 6 closes the lifting hole 10 of the guide tube 4 as the first time.

Therefore, the stopper 7 caught in any one of the selected adjusting grooves 5 and 5 'is no longer lifted and operated in the lifting hole 10 by the opening / closing portion 9 blocking the lifting hole 10. The length of the suction pipe 1 is selected by fixing and maintaining the state where 7 is locked on the adjustment grooves 5 and 5 'of the inner pipe 2.

In the stopper 7 which is caught on the adjustment grooves 5 and 5 'of the inner pipe 2, the opening and closing portion 9 of the slider 6 always closes the lifting hole 10 without the slider 6 being moved. The stopper 7, which is locked to the adjusting grooves 5 and 5 ′ of the inner pipe 2, is moved up and down even when the inner pipe 2 is moved to draw or insert the inner pipe 2 from the out pipe 3. The stopper 7 of the guide pipe 4 fixedly coupled to the adjusting grooves 5 and 5 'of the inner pipe 2 and the out pipe 3 is not fixed in the ball 10 and remains fixed. By maintaining the coupling relationship as a medium, the length of the suction pipe (1) is selectively made from this.

The springs 11 and 11 'which are elastically coupled to the caps 8 and 8' of the slider 6 on both sides of the guide tube 4 are fixed in the caps 8 and 8 'of the slider 6, respectively. It is elastically coupled stably without fluidity by the piece 13 to ensure smooth operability of the slider 6 and to stably provide the operability of the slider 6 for length adjustment.

In addition, the slider 6 and both caps 8 and 8 'are mutually assembled by the assembling protrusions 12 and the assembling grooves 12a, so that the assembling work is easily performed, as well as the slider 6 and the caps 8 on both sides. 8 ') will not run away.

On the other hand, it is built in the lifting hole 10 of the guide tube 4, and is moved up and down in the lifting hole 10 by the movement of the slider 6, and from there, the locking grooves 5, 5 'of the inner pipe 2 are moved. The stopper 7 to be locked or released is implemented by a round pin type or an elliptical pin type.

In the present invention, the stopper 7 is configured to have an elliptical shape in the vertical direction, and the stopper 7 which is caught by the catching grooves 5 and 5 'when the lifting hole 10 is closed by the opening / closing portion 9 of the slider 6. ) Is prevented from being lifted so that the locking state is not released, and conversely, when the lifting hole 10 is opened from the opening and closing part 9 and the stopper 7 is released from the locking state of the adjusting grooves 5 and 5 ', It is preferable to be able to impart a stable operability by being caught and released from the locking grooves 5 and 5 'while lifting up and down in the lifting hole 10 without completely leaving the lifting hole 10.

5 is a cross-sectional view illustrating another embodiment of the present invention, and FIG. 6 is an enlarged cross-sectional view of the main portion of FIG. 5, in which case the outpipe 3 is drawn from the inner pipe 2 as shown in FIGS. 7A and 7B. In order to move the slider 6a to one side, the actuating portion 16 of the slider 6a moves to one side from the outside of the guide tube 4 to compress the one-side spring 14 ', and this spring 14 With the compression of '), the stopper 7a with one side locking groove 15 coinciding with the lifting hole 10a is caught in the adjusting groove 5, 5' of the inner pipe 2 by the lifting hole 10a. Through the rising groove (15 ') side through it is in a state that can be separated from the adjusting groove (5, 5').

That is, in the state where the slider 6a is moved to one side as described above, the guide tube 4 is coupled by moving the guide tube 4 together with the movement of the operation unit 16 integrated with the slider 6a. Of the stopper 7a, which has been moved to the adjusting grooves 5 and 5 'and rides on the outer circumferential surface of the inner pipe 2, through the lifting hole 10a, to the rear side of the bottom of the slider 6a. Positioned toward the locking groove 15, the out pipe 3 is moved by the desired length from the inner pipe 2 as the slider 6a is moved.

As described above, when the slider 6a is pushed to one side and the out pipe 3 is drawn out from the inner pipe 2, the stopper 7a adjusts the locking groove 15 and the inner pipe 2 of the slider 6a. It selectively moves to the grooves 5 and 5 'and moves away.

That is, the stopper 7a is positioned on the outer circumferential surface of the inner pipe 2 through the elevating hole 10a formed in the operation portion 16 of the guide tube 4 moving together with the slider 6a. When the locking groove (15) of the slider (6a) is caught in the control groove (5,5 ') during the movement of the slider groove (5,5') to the side of the locking groove (15) And the adjustment grooves (5, 5 ') are respectively instantaneously coupled.

Therefore, when the user wants to extend the length of the suction pipe 1 by drawing the out pipe 3 from the inner pipe 2, the user operates the slider 6a forward to push the guide pipe 4 to the out pipe 3. After moving to the desired length and releasing the slider (6a) is returned to its original position by the restoring force of the spring (14 ') that was compressed from one side of the slider (6a) operating portion 16 to the stopper (7a) of the locking groove 15 Is caught by the adjusting grooves 5 and 5 'of the inner pipe 2 through the elevating hole 10a, the out pipe 3 can be moved from the inner pipe 2 to extend and adjust the suction pipe 1 to a desired length. Will be.

Of course, in order to reduce the length of the suction pipe 1 by inserting the out pipe 3 into the inner pipe 2, the other spring of the operating part 16 is also reversed by pulling the slider 6a to the other side and pulling out the other side. (14) is compressed and the stopper (7a) is caught in the side locking groove (15 ') to move the outpipe (3) to the inner pipe (2) side by increasing the length of the suction pipe (1) as described above It is to adjust the reduction.

As described above, according to the present invention, the user can grasp the sliders 6 and 6a by hand and push them in the desired direction so that the outpipe 3 moves in the desired length direction and when the sliders 6 and 6a are released at the selected length, Since the pipe 3 and the inner pipe 2 are fixed to each other, the suction pipe 1 can be adjusted to a desired length by one-touch operation.

As described in detail above, the present invention can adjust the length of the suction pipe 1 very easily by stretching the outpipe 3 from the inner pipe 2 to a desired length by one-touch operation, and the present invention is further simplified. By controlling the length of the suction pipe 1 as desired by the simple operation, it is possible to guarantee the ease of use of the vacuum cleaner as much as possible, and the suction pipe 1 can be compactly reduced, thereby eliminating inconveniences such as storage and movement. In particular, the sliders 6 and 6a, which are means for variably adjusting the length of the suction pipe 1, are configured in a flat type instead of a protruding structure to provide a compact and clean appearance of the suction pipe 1, and from this vacuum cleaner You can expect the benefits and effects such as can contribute to the design improvement.
