Description

Turning handle of vacuum cleaner

The present invention relates to a rotary handle of a vacuum cleaner, and more particularly, to a rotary handle of a vacuum cleaner in which a hose is not twisted by rotating a handle part of a vacuum cleaner rotary handle.

In general, a vacuum cleaner generates a vacuum by using a motor, and uses the same to suck and clean dirt such as dust. An example of such a vacuum cleaner is shown in FIG.

According to FIG. 1, such a conventional vacuum cleaner has a structure in which one side of the hose 3 is connected to a suction port 2 formed on the front side of the cleaner body 4 that is movable by wheels 7 coupled to both sides thereof. It is.

The other side of the hose (3) is connected to the hose connection portion 40 of the handle (1), one end of the multistage extension pipe (5) is connected to the extension pipe connection portion 30 of the handle (1), and the multistage extension pipe ( The other side of 5) is connected to the suction brush (6).

The handle (1) is attached to the suction force control device and the main body of the handle (10), the fixed handle portion 20 formed so that the user can grab when cleaning, and the extension pipe connecting portion 30 is connected to the extension pipe (5) And a hose connection portion 40 to which the hose 3 is connected.

In order to prevent the twisting of the hose 1 during cleaning, the hose connection portion 40 has a structure in which the hose 3 and the handle 1 can rotate relative to each other as shown in FIG. 2.

Referring to the drawings, the hose connection portion 40 is composed of a cover 43, the terminal 45, the holder 47. The terminal 45 is cylindrically coupled to one end of the hose 3. On the outside of the terminal 45, two ring-shaped protrusions 45a are spaced apart by a predetermined distance. The holder 47 is rotatably coupled with the terminal 45. The holder 47 has two ring-shaped grooves formed so as to correspond to the projection 45a of the terminal so that the terminal 45 can rotate inward. The holder 47 is fixed to the hose connecting portion 40 of the handle 1 by the cover 43.

Such a structure allows the holder 47 and the terminal 45 to rotate with each other. That is, the hose 3 and the handle 1 can be freely rotated with each other, so that the problem that the hose 3 is twisted during cleaning does not occur.

However, the rotation handle of the above structure has a problem in that the product cost is increased and the management cost of the parts is increased because additional parts are required to make a structure for the relative rotation of the handle and the hose. In particular, since the wire connecting the suction force control device and the motor in the cleaner body rotates to connect, there is a problem in that durability and contactability deteriorate.

The present invention has been made to improve the above problems, to provide a rotary handle of the vacuum cleaner to minimize the number of parts required while having a rotation structure to prevent the twisting of the hose by allowing the handle portion of the handle to rotate about the body. Its purpose is to.

In order to achieve the above object, the rotary handle of the vacuum cleaner according to the present invention includes a body having a suction force control device attached thereto, a handle portion formed to be grasped by a user during cleaning, and an extension pipe connection portion to which an extension pipe with a suction brush is attached; In the rotation handle of the vacuum cleaner made of a hose connection portion is connected to the hose body and the vacuum cleaner body, characterized in that the handle portion and the body is formed to be rotatable with each other.

One side of the body of the vacuum cleaner rotary knob is provided with a protrusion formed with a plurality of locking jaws, one end of the handle portion is provided with a groove formed to rotate the locking jaw of the protrusion.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the rotary handle of the vacuum cleaner according to the present invention. However, the same parts as in the prior art will be described using the same reference numerals.

Referring to the drawings, the rotation handle (1 ') is composed of a body (10'), handle portion (20 '), extension pipe connecting portion 30 and hose connecting portion (40').

One side of the body (10 ') is provided with a protrusion 11, the handle portion 20' is rotatably coupled. A plurality of locking jaws 11a protrude in the radial direction at the end of the protrusion 11. In addition, the body (10 ') is attached to the suction force adjusting device.

The handle portion 20 'has a form in which the handle portion 20 of the conventional handle 1 is cut and has a structure in which one end can be rotatably coupled to the protrusion 11 of the body. That is, there are a plurality of guide grooves 20'a through which the plurality of locking jaws 11a of the protrusion 11 can pass, and the locking jaws 11a are freely at the end of the guide grooves 20'a. A ring-shaped groove 20'b having a size that can be turned is formed. Therefore, the guide groove 20'a of the handle portion is aligned with the catching jaw 11a of the body 10 ', and then inserted, so that the catching jaw 11a is inserted into the groove 20'b inside the handle portion 20'. The handle portion 20 'can be rotated with respect to the torso 10'.

The hose connection portion 40 'is only configured to fix the hose 3 so that it does not rotate with respect to the handle but does not fall out. That is, the electric wire connecting the suction force adjusting device and the motor in the cleaner main body 4 does not have to be a rotary connection structure, and it is only necessary to fix it so that the electric wire does not move.

Extension pipe connecting portion 30 has the same structure as the structure that can attach and detach the extension pipe 5 as in the prior art.

The handle 1 'having the structure described above holds the handle 20' of the handle and cleans the handle 20 'according to the position of the suction brush 6 to the body 10' of the handle. Since it can rotate freely, the hose 3 fixed to the hose connection portion 40 'of the handle 1' is not twisted.

As described above, according to the rotary handle for a vacuum cleaner according to the present invention, since the handle portion of the handle rotates with respect to the body, the number of necessary parts can be minimized while preventing the hose from being twisted.

In the above described and preferred embodiments of the subject innovation, but also described, the subject innovation is not limited to the specific preferred embodiment described above, the subject innovation belongs without departing from the gist of the subject innovation claimed in the claims below Those skilled in the art will be able to implement various modifications.
