Description

Nozzle of vacuunm 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 the vacuum cleaner to facilitate suction of air including dust.

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

Such a vacuum cleaner should flow smoothly until the air sucked from the suction nozzle is sucked into the cleaner body, and the dust should be easily separated from the air including the dust. This is an important criterion for determining the performance of the vacuum cleaner.

On the other hand, the suction nozzle of the vacuum cleaner may be proposed in various shapes and sizes depending on the type of the surface to be cleaned. A slightly larger suction nozzle may be used to clean the floor, but a slimmer nozzle may be more convenient when cleaning narrow corners or under the bed.

Vacuum cleaners can also be used to clean the surface to be cleaned, such as a bed mattress or carpet. Bed mattresses or carpets typically include a fiber material. The fiber material may contain not only large foreign matter but also fine foreign matter.

In this case, the foreign matter is not easily sucked into the main body of the vacuum cleaner only by the suction force of the nozzle. In particular, the fine foreign matter tends to be compressed in the state of being sandwiched between the fiber tissues, so that it is not easily sucked into the nozzle.

Therefore, the user has to inconvenience by using a separate hand or utensil to remove dust contained in the bed mattress or carpet.

The present embodiment aims to provide a nozzle of a vacuum cleaner that allows foreign matter present on the surface to be cleaned to be easily sucked into the body of the cleaner.

Another object of the present invention is to provide a nozzle of a vacuum cleaner capable of collecting foreign matter from a surface to be cleaned so that foreign matter can be easily sucked into the body of the vacuum cleaner.

It is also an object of the present invention to provide a nozzle of a vacuum cleaner that allows foreign matter to be separated from the surface to be cleaned without disturbing the movement of the suction nozzle.

The nozzle of the vacuum cleaner according to the present embodiment, The nozzle body of the vacuum cleaner according to the present embodiment, the nozzle body is formed with an air suction; An agitator provided to be movable in the nozzle body to separate foreign matter from the surface to be cleaned; And a foreign material collecting part provided on one side of the agitator and allowing foreign matter to be collected separately from the surface to be cleaned.

According to the embodiment of the above configuration, there is an advantage that the dust contained in the surface to be cleaned can be easily suctioned into the body of the cleaner. In particular, the effect of tapping the surface to be cleaned by the agitator is generated, the effect that the foreign matter is collected from the surface to be cleaned by the foreign matter collecting portion.

In addition, since the foreign matter collecting portion is provided in a shape corresponding to the bottom portion of the nozzle, there is an effect that the nozzle can be moved without being disturbed by the foreign matter collecting portion.

In addition, since foreign matters such as fine dust on the surface to be cleaned can be easily sucked into the cleaner body, there is an advantage that the cleaning performance can be improved.

Hereinafter, with reference to the drawings will be described a specific embodiment of the present invention. However, the spirit of the present invention is not limited to the embodiments presented, and those skilled in the art who understand the spirit of the present invention can easily suggest other embodiments within the scope of the same idea.

Here, the center line c1 of the connection shaft 123 is spaced apart from the center line c2 of the first connection part 132 by a predetermined distance d1. Therefore, when the connecting shaft 123 is rotated, the first connecting portion 132 is rotated around the center line c1 with the distance d1 as the rotation radius.

In other words, the first connecting portion 132 may be regarded as being eccentrically rotated with respect to the connecting shaft 123.

The link body 131 is linearly moved in the left and right directions while the first connection part 132 is rotated. That is, the rotational movement of the connecting shaft 123 is converted into linear movement by the link member 130.

When the link body 131 is linearly moved, the second connecting portion 133 may be linearly moved along the link body 131.

One side of the link member 130 is provided with a linear moving part 140 coupled to the second connection part 133 and moved in the left and right directions.

In addition, the nozzle body 100 is formed with a guide groove 105 for guiding the movement of the linear moving part 140. The linear moving part 140 may be moved in the horizontal direction while being inserted into the guide groove 105.

The agitator 150 which is moved in the horizontal direction by the linear movement unit 140 is coupled to the lower side of the linear movement unit 140. That is, the linear movement unit 140 and the agitator 150 may be moved at the same time.

In the process of moving the agitator 150, the agitator 150 may pressurize the surface to be cleaned, and thus foreign matter may be separated from the surface to be cleaned.

On the other hand, the nozzle body 100 is further provided with a first foreign matter collecting unit 160 for separating and collecting foreign matter from the surface to be cleaned. The first foreign matter collecting unit 160 may be disposed in the suction unit 101.

Here, a roller is applicable to the rotating unit 161, a rotating shaft is applicable to the rotation center 162. Since the rotating unit 161 is easily rotated while the suction nozzle is moved, the rotating unit 161 does not interfere with the movement of the suction nozzle.

When the rotating part 161 is rotated while being in contact with the surface to be cleaned, foreign matter may be separated from the surface to be cleaned and may be raised along the rotating part 161.

The foreign matter collected by the rotating part 161 is guided by the rotating part 161 and moved to the suction part 101, and then moved into the cleaner body.

The rotating part 161 may be made of a rubber material. In this case, static electricity is generated between the foreign material on the surface to be cleaned and the rotating part 161 so that the foreign material can be easily moved toward the rotating part 161. In particular, when the foreign material is a hair of a hair or a pet, it may be easily separated from the surface to be cleaned and collected on the rotating part 161.

On the other hand, a felt material may be applied to the outer circumferential surface of the rotating unit 161. In this case, the foreign matter may be buried in the felt material and separated from the surface to be cleaned.

By the above configuration, the foreign matter is easily separated from the surface to be cleaned, there is an effect that can be collected by the foreign matter collecting unit and introduced into the cleaner body.
