Description

The nozzle of vacuum cleaner

This embodiment relates to a nozzle of a vacuum cleaner.

The present embodiment relates to a nozzle of a vacuum cleaner, and more particularly, to a nozzle of a vacuum cleaner to improve the nozzle structure of a vacuum cleaner to facilitate cleaning of corners of a surface to be cleaned.

In general, a vacuum cleaner is a device that sucks air containing dust by using suction power generated by a suction motor mounted inside the main body, and then filters the dust inside the main body.

The vacuum cleaner may be distinguished by a canister method in which a suction nozzle which allows dust on the bottom surface to be sucked separately from the main body and connected by a connection device, and an upright method in which the suction nozzle is integrally formed with the main body.

On the other hand, the upright vacuum cleaner, the suction nozzle for sucking the air containing dust while moving along the bottom surface, rotatably coupled to the suction nozzle, the main body is built in the suction motor, and the upper portion of the main body It includes a handle that is installed and allows the user to grip when cleaning, and a dust collecting device mounted to the main body.

In addition, the suction nozzle is provided with a moving wheel for easily moving the main body, and the rear side of the suction nozzle is provided with a rotation lever to enable the main body to rotate at a predetermined angle with respect to the suction nozzle.

The operation of the vacuum cleaner will be described briefly.

In order to perform cleaning, the rotation lever is operated so that the main body is inclined at a predetermined angle with respect to the suction nozzle.

Then, when the vacuum cleaner is operated, suction force is generated by the suction motor built into the main body. Then, the air containing the dust is sucked through the suction nozzle, the sucked air is introduced into the dust collector.

The dust separated from the air introduced into the dust collecting apparatus is stored in the dust collecting apparatus, and the dust separated air is discharged from the dust collecting apparatus and discharged from the one side of the main body after being introduced into the main body. do.

By the way, according to the vacuum cleaner as described above, the air suction unit for allowing air to be sucked from the surface to be cleaned is formed on the bottom surface of the suction nozzle.

And, since the suction nozzle performs cleaning while moving the bottom surface, it is possible to clean the bottom surface, but it is difficult to perform the cleaning due to the weak suction force acting on the corner portion where the wall surface and the bottom surface meet other than the bottom surface. have.

Therefore, there is a need for a vacuum cleaner capable of cleaning not only the bottom surface but also the edge portion.

Here, the agitator 40 may be located in front of the side brush 32 or arranged at least in parallel with the side brush 32.

Therefore, foreign substances located in the front and side portions of the suction nozzle 20 can be separated from the surface to be cleaned by the operation of the agitator 40 and the side brush 32.

Hereinafter, the operation of the suction nozzle 20 will be described.

7 is a plan view showing a state in which the nozzle according to the present embodiment is moved to the front, Figure 8 is a plan view showing the state in which the nozzle according to the present embodiment hits an obstacle in the front.

7 and 8, in the state in which the external force is not applied to the suction nozzle 20 according to the embodiment of the present invention, the moving bracket 30 is cleaned in a state in which the external bracket is pulled forward, and the external force is applied. In this case, the cleaning may be performed while the moving bracket 30 is inserted into the head 24.

In detail, when the cleaning is performed in the process of moving the vacuum cleaner to the front, the moving bracket 30 is drawn out to the front of the head 24 is maintained.

In addition, the side brushes 32 are rotated to separate foreign materials located on both sides of the suction nozzle 20 from the surface to be cleaned and to be moved to the center portion of the head 24.

Of course, the foreign material located in the front center of the head 24 may be separated from the surface to be cleaned by the agitator 40 rotated to be sucked into the main body 10.

On the other hand, if there is an obstacle such as the wall 80 in front of the vacuum cleaner, the moving bracket 30 may hit the wall 80 in the process of moving the vacuum cleaner.

In this case, the movement bracket 30 may be moved rearward and drawn into the head 24. Of course, the pressing force applied to the suction nozzle 20 by the wall 80 should be more than the elastic force of the spring 60.

In addition, when the moving bracket 30 is completely moved backward, the agitator 40 may be exposed to the front of the head 24.

Then, the agitator 40 may act to separate the foreign material located at the corner portion where the wall 80 and the bottom surface meet. Therefore, the foreign material located in the corner portion can be easily cleaned.

As a result, when the bottom surface is cleaned using a vacuum cleaner, the bottom surface is the side brush 32 and the agitator 40 while the agitator 40 is positioned inside the head 24. By the cleaning can be easily made.

On the other hand, when the vacuum cleaner hits the wall surface, the foreign material accumulated in the corner portion where the bottom surface and the wall meet in the state where the agitator 40 is exposed in front of the head 24 can be easily cleaned. .
