Pipes structure of a vacuum cleaner having a power supplying pipe}

The present invention relates to a pipe structure of a vacuum cleaner, and more particularly, a power supply pipe for supplying power to a motor installed in a brush of a vacuum cleaner that sucks dust or foreign matters and operating to efficiently suck dust or foreign matters. The present invention relates to a pipe structure of a vacuum cleaner having a power supply tube, which is added to the suction tube to enhance the appearance of the vacuum cleaner and to adjust the length of the suction tube and the power supply tube as necessary.

In general, the vacuum cleaner sucks dust or foreign substances scattered on the floor by using a suction force generated by the driving of the motor built into the cleaner body through a brush, and a suction pipe connected through a dust collecting chamber and a flexible hose. By means of suctioning dust and foreign matter into the dust collection room by means of a device that performs the cleaning operation automatically.

For example, the configuration of a conventional vacuum cleaner is the same as that shown in FIG. 1, which includes a hose 3 communicating with an intake port 2 in front of a cleaner body 1 having a motor fan, and a handle provided at a tip thereof. (4), a plurality of detachable suction pipes 5, and a brush 6 are provided. When the vacuum cleaner is operated, suction power is generated by the motor fan, and dust or foreign matter is sucked through the brush 6.

On the other hand, there is provided with a motor in the brush to efficiently clean the dust and the like on the floor, bar will be described schematically with reference to FIG.

As can be seen in Fig. 2, two rollers 6a are attached to the brush 6, a motor M is mounted at a suitable place of the brush 6, and a pulley 6B is attached to the shaft of the motor M. It is fixed, and the cleaning roller 6d is rotatably attached to this via the belt 6c.

Therefore, the conductive wire 7 for the motor applied voltage is connected to the motor M. For this purpose, it is conventionally extended to the handle 4 along the length of the suction pipe 5 as shown in FIG. 1, and the switch 8 By turning on / off), not only the motor M but also the motor fan in the cleaner main body 1 were operated to generate a strong suction force.

However, depending on the place to be cleaned, there may be a case in which the length of the provided hose and the suction pipe is too long or insufficient, so that it is difficult to clean the wire shown in FIG. Since it is fixed, not only its appearance is not good, but also there is a problem that can not actively respond to the extension or contraction of the suction pipe (5).

The present invention is devised to solve the above problems, the object of the present invention is to install a brush in the vacuum cleaner that sucks dust or foreign matter to supply power to the motor that operates to efficiently suck the dust or foreign matter, etc. It is to provide a pipe structure of the vacuum cleaner having a power supply tube for adding a power supply tube for the suction tube to make the appearance of the vacuum cleaner beautiful and at the same time to properly adjust the length of the suction tube and the power supply tube.

A plurality of pressing protrusions 54c are formed.

In addition, the cover 56 is provided with a plurality of fixing grooves 56a into which the hooks 51b of the fixing member 51 are inserted and coupled to protect the movable member 54.

On the other hand, the housing 58 is fixed to one end of the movable member 54, and the connector 57 is connected to the other end thereof.

The state of adjusting the length of the vacuum cleaner pipe according to the present invention configured as described above will be described.

5 shows that the fixing protrusions 42a of the locking plate 42 are fitted into the two locking grooves 21a of the suction inner pipe 21, respectively, and the pressing plates 43 restrain the locking plate 42. It is a state. At this time, as shown in Figure 10, the operating projections (44a) of the sliding cover is located at the bottom end of the cam groove (43a) of the two pressing plate (43) (see Figures 10 and 11).

In this state, when the sliding cover is pushed or pulled as shown in FIG. 7, the actuating protrusions 44a are simultaneously moved in the axial direction, and the two pressing plates 43 are controlled by the restricting protrusions 41a and 41b of the sleeve 41. Since the axial movement is restricted, as shown in FIG. 7, the two pressing plates 43 are circumferentially separated from each other along the restricting protrusions 41a and 41b by the V-shaped cam groove 43a into which the actuating protrusions 44a are fitted. It is slid and released from the locking plate 42. Then, the locking plate 42 is released by restraining by the pressing plates 43, thereby freeing the inner pipes 21 and 22 so that they can be relatively moved relative to the outer pipe 30 (FIG. 12). And FIG. 13).

That is, when the inner pipe 21 or 22 is pulled in the direction of the arrow while the restraint of the locking plate 42 is released, as shown in FIG. 12 by the external force applied to the inner pipe 21, the locking plate ( As the elastic piece 42b of the 42 is elastically deformed, the fixing protrusions 42a are removed from the locking groove 21a of the inner pipe 21 so that the length of the inner pipe 21 or 22 can be adjusted. Will be. At this time, since the locking plate 42 is always elastically biased downward by the elastic pieces 42b, the locking groove of the inner pipe 21 of which the length is adjusted even if the force applied to the sliding covers 44 and 45 is not removed. Respective fixing protrusions 42a are elastically fitted to the inner pipe 21 to temporarily fix the inner pipe 21.

Next, when the length of the suction inner pipe 21 and the inner pipe 22 is properly adjusted and the force applied to the sliding covers 44 and 45 is removed, the sliding cover is resilient by the resilience of the coil spring 46. (44,45) returns to the initial position intermediate. Accordingly, the two pressing plates 43 are moved in a direction in which the pressing plates 43 are close to each other by the cam grooves 43a coupled with the operation protrusions 44a of the sliding covers 44 and 45 to cover the upper part of the locking plate 42. 42). Then, the inner pipes 21 and 22 are fixed very firmly to a position arbitrarily set with respect to the outer pipe 30 (see FIGS. 5, 8, 10 and 11).

When the inner pipes 21 and 22 are stretched and contracted as described above, as shown in FIGS. 6 and 9, the movable piece 54a formed in the movable member 54 is fixed to the fixed piece 51. 53 is moved in contact with the wire, so that the voltage applied to the plug 53 is transferred to the wire 55 via these fixing pieces 53 and the movable piece 54a, and thus the conductor wire is installed and connected to one end of the connector 57. The voltage is applied to the motor mounted in the brush of the vacuum cleaner through (not shown) to double the suction or cleaning power of the dust.

As described above, according to the present invention, the locking plate has two fixing protrusions spaced apart from each other so that the locking plate is inserted into two adjacent locking grooves of the inner pipe at the same time to fix the position. Therefore, the internal pipe can be fixed very firmly and stably at any set position, thereby easily supplying voltage to the motor mounted in the brush, and the length of the suction pipe and power supply pipe can be adjusted as necessary. It can be properly adjusted, and the power supply pipe is in the inside of the pipe has the advantage of a very beautiful appearance.

Although the present invention has been described with reference to the accompanying drawings, the present invention is not limited thereto, and many variations and modifications may be made within the following claims. For example, the power supply pipe is formed in a half moon shape, but may be transformed into other suitable shapes as necessary.
