Description

Vacuum cleaner {VACUUM CLEANER}

The present invention relates to a vacuum cleaner having a suction blade that rotates for convenient use and storage.

Generally, a vacuum cleaner generates a suction force by rotation of a fan motor by a power source applied to a cleaner main body. At this time, an electric appliance that forcibly removes dust or foreign matter in a space for use of the vacuum cleaner through a suction nozzle by a suction force generated, thereby cleaning is performed.

Conventional vacuum cleaners have been created to solve the inconvenience that the suction head is not collapsed after using the vacuum cleaner because it is not folded.

In order to fully understand the present invention, operational advantages of the present invention, and objects achieved by the practice of the present invention, reference should be made to the accompanying drawings and the accompanying drawings which illustrate preferred embodiments of the present invention.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, and the present invention will be described in detail. However, the present invention can be implemented in various different forms, and is not limited to the embodiments described. In order to clearly describe the present invention, parts that are not related to the description are omitted, and the same reference numerals in the drawings denote the same members. BRIEF DESCRIPTION OF THE DRAWINGS In the entire specification, when a section includes a constituent element, it does not exclude other constituent elements, but may include other constituent elements, unless specifically stated otherwise.

1 to 5, a vacuum cleaner 10 according to an embodiment of the present invention includes a main body 100 including a dust collecting device 110, a main body 100 attached to the main body 100, A suction pipe 300 for suctioning dust, and a suction head 200 attached to an end of the suction pipe 300.

Here, the suction head 200 includes two or more suction vanes 220 rotatably coupled to the rotating body 210 and the rotating body 210. The main body 211 is fixed to the inside of the rotating body 210. It is preferable that the rotation axis of the main gear 211 is disposed so as to be perpendicular to the bottom surface of the suction head 200.

At least two suction blades 220 are provided and extend to both sides of the rotating body 210. At least one suction port 230 for introducing outside air and dust is formed on the bottom surface of the suction wing 220 and a switch 240 is formed on the upper surface to rotate the suction wing 220 about the rotating body 210 Perform the operation. The suction vane 220 is independently rotatable with respect to the rotating body 210.

The mechanism by which the suction wing 220 rotates with respect to the rotating body 210 will be described in detail as follows.

A sub gear 221 is provided at one side of the suction vane 220 to engage with the main gear 211 disposed on the rotating body 210. It is preferable that the rotation axis of the sub gear 221 is an axis parallel to the rotation axis of the main gear 211. [ A rotation rod 250 that rotates by the operation of the switch 240 is provided on the other side of the inside of the suction blade 220. A gear (rotation shaft gear) is formed on at least a part of the surface of the rotation bar 250. It is preferable that the rotation axis of the rotation bar 250 is parallel to the rotation axis of the sub gear 221. A rod 260 is disposed in a space between one side and the other side of the suction vane 220 so as to intersect the rotation axis direction of the rotation bar 250 and the sub gear 221.

At this time, a gear portion (rod gear) is formed on at least both ends of the rod 260. The rod gear formed at one end of the rod 260 is screwed to the rod of the rod 260, The gear is screwed with the sub gear 221 described above. The rotation of the rod 260 by the operation of the switch 240 rotates the rod 260 and the rotation of the rod 260 rotates the sub gear 221 and the sub gear 221 rotates the main gear 211 and rotates with respect to the main gear 211. As a result, the suction vane 220 can rotate around the rotating body 210.

Meanwhile, the suction head 200 may include at least one moving means 270 at a lower portion thereof. Specifically, the suction head 200 may have a plurality of moving means receiving grooves 280, and the moving means 270 such as a wheel may be inserted into the moving means receiving groove 280, (200).

According to this configuration, since the suction head 200 for sucking outside air and dust when cleaning is configured to be rotatable with respect to the rotating body 210, there is an advantage that a portion that is not easy to clean can be easily and easily cleaned . In addition, since two or more suction heads 200 extending to both sides of the suction body of the vacuum cleaner 10 are folded so as to be close to each other by rotational operation, the volume of the vacuum cleaner 10 can be reduced, There is an advantage of easy storage.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood. For example, a person skilled in the art can change the material, size, etc. of each component according to the application field, or can combine or replace the disclosed embodiments in a form not explicitly disclosed in the embodiment of the present invention, And the scope of the present invention is not limited thereto. The embodiments described above are therefore to be considered in all respects only as illustrative and not restrictive. It should be noted that the modified embodiments are all included in the technical idea described in the claims of the present invention.
