The agitator functions to shake off the foreign matter adsorbed on the carpet while rotating, and is configured to operate together with the operation of the vacuum cleaner.

By the way, when the agitator is provided in the suction nozzle as described above, cleaning of the surface to be cleaned such as a carpet becomes easy, but when cleaning the foreign material of the surface to be cleaned such as a floor, cleaning performance is deteriorated by rotation of the agitator. Problems will arise.

That is, the foreign matter on the surface to be cleaned is not sucked into the suction port of the suction nozzle by the rotation of the agitator, and the foreign material remains on the surface to be cleaned even when cleaning is performed because it is shaken out of the suction nozzle. Done.

Therefore, there is a need for a suction nozzle that allows proper cleaning to be performed in accordance with the condition of the surface to be cleaned.

1 is an external perspective view of a suction nozzle of a vacuum cleaner according to the spirit of the present invention, and FIG. 2 is an exploded perspective view of the suction nozzle.

1 and 2, the suction nozzle 10 according to the spirit of the present invention is rotatably coupled to the main body 100 and the rear side of the main body 100 to suck the foreign matter on the surface to be cleaned, Suction pipe 400 is included to allow the air containing the foreign matter sucked into the main body 100 to be moved to the cleaner body.

In addition, the main body 100 is coupled to the nozzle body 200 forming the lower appearance of the suction nozzle 10 and the upper side of the nozzle body 200 to form the upper appearance of the suction nozzle 10. It consists of a cover member 300.

In addition, the main body 100 inside the cleaning member 220 to facilitate the cleaning of the surface to be cleaned, such as carpet, the rotating member 240 to enable the rotation of the cleaning member 220, and the state of the surface to be cleaned According to the user's operation includes a control member 280 to control the rotation of the rotating member 240.

In detail, a suction port 202 (see FIG. 5) is formed at a lower front end portion of the nozzle body 200 to allow foreign substances on the surface to be cleaned to be sucked. In addition, the cleaning member 220 is provided on the upper side of the suction port 202 (see FIG. 5) to facilitate cleaning of a carpet or the like.

In addition, the cleaning member 220 is configured to be rotatable in a state seated on the nozzle body 200.

The cleaning member 220 is coupled to both sides of the body 222 is formed in a substantially cylindrical shape, the brush 224 is provided spirally formed on the outer peripheral surface of the body 222, the body 222 A coupling part 226 is included to allow the cleaning member 220 to be coupled to the nozzle body 200.

At this time, the body 222 is rotatably coupled to the coupling portion 226 to enable the cleaning member 220 to rotate.

In addition, a connection pulley 228 is formed at one side of the body 222 so that the transmission belt 250 for transmitting the rotational power of the rotating member 240 to be described later is maintained in a state of maintaining a tensile force.

Here, in order to fix the coupling part 226 to the nozzle body 200, a coupling part seating end 204 on which the coupling part 226 is seated is formed in the nozzle body 200.

Therefore, the cleaning member 220 is rotatable by the power transmitted by the transfer belt 250 in a state seated on the nozzle body 200 by the coupling portion 226.

On the other hand, the rear side of the cleaning member 220 is provided with a rotating member 240 to enable the rotation of the cleaning member 220.

In detail, the rotating member 240 is configured to be rotatable by air introduced from the outside. To this end, the rotating member 240 is provided with a plurality of blades 242 at regular intervals.

In addition, a rotation shaft 244 penetrates and is coupled to a central portion of the rotation member 240. And, one side of the rotating shaft 244 is surrounded by a transmission belt 250 for transmitting the rotational power of the rotating member 240 to the cleaning member 220.

Therefore, when the rotating member 240 is rotated, the transmission belt 250 surrounded by the rotating shaft 244 is rotated, the rotational power of the rotating member 240 by the transmission belt 250 is the cleaning member And the cleaning member 220 is rotated.

Here, the nozzle body 200 has a partition portion 210 that partitions the space provided with the cleaning member 220 and the space provided with the rotating member 240 is formed long left and right.

That is, the cleaning member 220 is provided in front of the partition 210, and the rotating member 240 is provided at the rear of the partition 210.

In addition, an air flow path 216 is formed at a rear side of the partition 210 to allow air containing foreign matter sucked through the suction port 202 (see FIG. 5) to be moved to the suction pipe 400. In the partition 210, inlet holes 212 and 214 are formed to allow air containing foreign matter into the air passage 216.

In detail, the inlet holes 212 and 214 are formed on the left side of the inlet hole 212 formed on the left side with respect to the center of the air passage 216 and on the right side of the center of the air passage 216. The right inlet hole 214 is included.

At this time, the rotating member 240 is located on the air flow path 214, it is located immediately after the right inlet hole 214. That is, the rotating member 240 is formed to be biased toward the right inlet hole 214 in the air passage 216.

In other words, the thickness of the rotating member 240 is approximately half the width of the air flow path 216, and the rotating member 240 is positioned at the rear side of the right inlet hole 214.

By such a configuration, when the air containing the foreign matter sucked through the suction port 202 (see FIG. 5) is introduced into the air flow path 216 through the left inlet hole 212, the air flow path 216. The air introduced into the air does not pass through the rotating member 240 and is immediately moved to the suction pipe 400.

On the other hand, if the air containing the foreign matter sucked through the inlet 202 flows into the air passage 216 through the right inlet hole 214, the air containing the foreign substance introduced into the air passage 216 Is moved to the rear side while rotating the rotating member 240.

That is, when air flows into the air flow path 216 through the left inlet hole 212, the rotating member 240 maintains a stopped state and the air flow path through the right inlet hole 214. When air is introduced into 216, the rotating member 240 is rotated by the introduced air.

At this time, the left inlet hole 212 and the right inlet hole 214 allows the air to be introduced into a single air flow path 216, the left and right inlet hole (212, 214) is opened at the same time In the state, the rotating member 240 is always rotated.

Accordingly, in the present invention, the adjusting member 280 is provided to allow the left and right inlet holes 212 and 214 to be selectively shielded (or selectively opened) according to the state of the surface to be cleaned.

Specifically, when cleaning the surface to be cleaned such as a floor, the left inlet hole 212 is opened by the adjustment member 280, the right inlet hole 214 is shielded so that the rotating member 240 is Keep it stationary.

On the other hand, when cleaning the carpet and the surface to be cleaned, the left inlet 212 is shielded by the adjustment member 280, the right inlet 214 is opened to allow the rotating member 240 to rotate. .

Hereinafter, the configuration of the adjusting member 280 to selectively shield the left and right inlet holes 212 and 214 as described above will be described in detail.

3 is a front perspective view of the adjustment member according to the spirit of the present invention, Figure 4 is a rear perspective view of the adjustment member according to the spirit of the present invention.

3 and 4, the adjustment member 280 is rotatably supported by the support rib 206 of the nozzle body 200, and selectively selects the left and right inflow holes 212 and 214. Shield.

In detail, the adjustment member 280 is the operation unit 282 to enable the user's operation, and the rotation control unit 290 to enable selective shielding of the left inlet hole 212 and the right inlet hole 214. And, the connection member 288 for transmitting the operating force of the operation unit 282 to the rotation control unit 290 is included.

In more detail, the operation unit 282 is exposed to the upper side of the suction nozzle 10 as shown in Figure 1 so that the user can operate from the outside of the suction nozzle 10. To this end, a through hole 302 (see FIG. 2) is formed at an upper side of the upper cover 300 to allow the operation unit 282 to be exposed to the outside.

Therefore, as the adjusting member 280 is rotatably provided in the main body 100, and the operation unit 282 is exposed to the outside of the main body 100, the user can easily operate the operation unit 282. Will be.

At this time, the operation of the operation unit 282 may be made by pressing the foot of the user, and thus the operation unit 282 preferably has a strength that can withstand the pressing force.

In addition, an upper portion of the manipulation unit 282 is formed to be rounded to a predetermined portion to facilitate the user's operation. That is, the concave portion 283 is formed above the operation portion 282.

At this time, the concave portion 283 may be provided with a display for allowing the user to accurately operate the operation portion 282 according to the state of the surface to be cleaned. Such an indication may for example be a floor representing a carpet and a general floor.

In addition, a guide rib 284 is formed below the operation unit 282 to guide the adjustment member 280 to be rotated within a range of a predetermined angle.

Here, the nozzle body 200 is provided with a limit setting rib 208 for setting the rotational limit of the guide rib 284. The guide rib 284 is then moved within the range of the limiting rib 208.

Accordingly, the adjustment member 280 is limited in the rotation range to a predetermined angle by the interaction of the guide rib 284 and the limiting rib 208.

On the other hand, the rotation control unit 290 is formed to be round to surround a predetermined portion of the rotation member 240 in front of the rotation member 240.

In addition, the rotation control unit 290 has a left communication hole 292, the right inlet hole 214 and the air flow path 216 to enable communication between the left inlet hole 212 and the air flow path 216. ), A right communication hole 294 is formed to allow communication.

At this time, the left communication hole (292) and the right communication hole (294) is formed on the rotation control portion 290 is formed differently.

That is, the left communication hole 292 is relatively formed in the lower side of the rotation control unit 290, as shown in Figure 4, the right communication hole 294 is relatively the upper side of the left communication hole (292). Is formed.

The reason why the position of the left communication hole 292 and the right communication hole 294 are formed differently as described above is due to the rotation of the adjustment member 280, the left inlet hole 212 or the right inlet hole 214. This is to selectively shield.

Due to the positional relationship between the left communication hole 292 and the right communication hole 294, a left shielding surface 293 selectively shielding the left inlet hole 212 above the left communication hole 292. Is formed, and a right shielding surface 295 for selectively shielding the right inflow hole 214 is formed below the right communication hole 294.

Therefore, when the left inlet hole 212 and the air flow path 216 are communicated by the left communication hole 292, the right inlet hole 214 is shielded by the right shielding surface 295, When the right inlet hole 214 and the air passage 216 communicate with each other by the right communication hole 294, the left inlet hole 212 is shielded by the left shielding surface 293.

As such, as the rotation of the rotating member 240 is controlled by the adjustment member 280, the user may select an optimal cleaning method according to the state of the surface to be cleaned, and thus, regardless of the state of the surface to be cleaned. It is possible to completely clean the surface to be cleaned.

Here, the present embodiment is characterized in that the rotating member 240 is located immediately after the right inlet hole 214, on the other hand, the rotating member 240 is immediately after the left inlet hole 212 It may be located at.

In this case, the positions of the left and right communication holes 292 and 294 should be reversed.

5 is a bottom perspective view of the suction nozzle.

Referring to FIG. 5, an opening and closing member 270 is detachably provided under the suction nozzle 10 to allow the inside of the air flow path 216 or the rotating member 240 to be cleaned.

In detail, as described above, the air including the foreign matter on the surface to be cleaned flows through the left inlet hole 212 or the right inlet hole 214 as described above. The foreign matter may remain in the air passage 216, in particular, the rotating member 240 while the air containing the foreign matter on the surface to be cleaned flows inside the air passage 216.

As such, when foreign matter remains in the air passage 216 or the rotating member 240, the flow of air in the air passage 216 and the rotation of the rotating member 240 may not be smoothly performed. In the present invention, the opening and closing member 270 is detachably provided at the lower side of the suction nozzle 10 to enable the user to clean the air flow path 216 and the rotating member 240.

Hereinafter, the operation of the suction nozzle 10 of the vacuum cleaner having the above configuration will be described.

FIG. 6 is a view showing an operating state of the suction nozzle when cleaning the surface to be cleaned such as a floor, and FIG. 7 is a view showing an operating state of the suction nozzle when cleaning the surface to be cleaned, such as a carpet. to be.

First, with reference to FIG. 6, the operation state of the said suction nozzle at the time of cleaning the to-be-cleaned surface like a floor is demonstrated. In this case, when the cleaning surface such as the floor is performed, the cleaning member 220 is preferably not rotated.

When the suction force generated by the vacuum cleaner is generated, air containing foreign matter on the surface to be cleaned is sucked through the suction port 202. In this process, in order to clean the surface to be cleaned such as the floor, the user presses the rear side of the operation unit 282 with his feet.

Then, the operation unit 282 is rotated at a predetermined angle in the clockwise direction. And the rotational force of the operation unit 282 is transmitted to the rotation control unit 290 by the connection member 288 to rotate the rotation control unit 290 at a predetermined angle in the clockwise direction.

Then, the left inlet hole 212 communicates with the air passage 216 by the left communication hole 292, while the right inlet hole 214 is shielded by the right shielding surface 295.

In this case, the air containing the foreign matter sucked into the suction nozzle 10 through the suction port 202 flows into the air passage 216 through the left inlet hole 212.

At this time, since the rotating member 240 is located at the rear side of the right inlet hole 214, the air introduced into the air passage 216 through the left inlet hole 212 is connected to the rotating member 240. It does not pass, but is moved to the suction pipe 400 side.

Accordingly, the rotating member 240 is in a stopped state, and as a result, the cleaning member 220 is in a stopped state.

As such, since the cleaning member 220 is not rotated when cleaning the surface to be cleaned, such as a floor, the foreign body of the surface to be cleaned is prevented from being shaken out of the suction nozzle 10 by the rotation of the cleaning member 220. Therefore, there is an effect that the cleaning of the surface to be cleaned can be made completely.

The air moved to the suction pipe 400 is finally introduced into the cleaner body.

On the other hand, in order to clean the surface to be cleaned such as a carpet, the user presses the front side of the operation unit 282 with his feet.

Then, the operation unit 282 is rotated at a predetermined angle in the counterclockwise direction. And, when the operation unit 282 is rotated in the counterclockwise direction, the rotational force of the operation unit 282 is transmitted to the rotation control unit 290 by the connecting member 288, the rotation control unit 290 is half Rotated clockwise at an angle.

Then, the right inlet hole 214 communicates with the air passage 216 by the right communication hole 294, while the left inlet hole 212 is shielded by the left shielding surface 293.

In this case, the air containing the foreign matter sucked into the suction nozzle 10 through the suction port 202 flows into the air passage 216 through the right inlet hole 214.

At this time, since the rotating member 240 is located at the rear side of the right inlet hole 214, the air introduced into the air passage 216 through the right inlet hole 214 is connected to the rotating member 240. While passing through the air flow path 216 is moved to the rear, the rotating member 240 is rotated by the air.

Here, since the right communication hole 294 is located in front of the lower side of the rotating member 240, the rotating member 240 is rotated in the counterclockwise direction.

When the rotation member 240 is rotated in the counterclockwise manner as described above, the transmission belt 250 coupled to the rotation shaft 244 of the rotation member 240 is rotated, and the rotation member is rotated by the transmission belt 250. The rotational power of 240 is transmitted to the cleaning member 220 so that the cleaning member 220 is rotated in the counterclockwise direction.

Then, the suction and foreign material is shaken off by the rotation of the cleaning member 220, the foreign matter is sucked into the suction nozzle 10 through the suction port 220.

Therefore, when cleaning the surface to be cleaned such as a carpet, the rotary member 240 is rotated by the outside air, and as the cleaning member 220 is rotated, foreign matter adsorbed on the carpet or the like is easily removed from the carpet or the like. Removed.

As the foreign matter adsorbed on the carpet is removed from the carpet or the like, the cleaning can be completely performed.

As described above, in order to clean the inside of the air flow path 216 or the rotating member 240, the user may separate the opening / closing member 270 from the suction nozzle.

Here, the present embodiment is characterized in that the rotating member 240 is located inside a single air flow path 216, otherwise, the flow path for air for rotating the rotating member 240 and the rotation The flow path through which air which does not rotate the member 240 flows may be formed separately.

That is, the partition rib which partitions the air flow path 216 is partitioned into a first air flow path not provided with the rotation member 240 and a second air flow path provided with the rotation member 240, and a floor and Air may be flowed into the first air flow path when cleaning the same surface to be cleaned, while air may be flowed into the second air flow path when cleaning the surface to be cleaned, such as a carpet.

According to the present invention as proposed, the rotation of the cleaning member to shake off the foreign matter on the surface to be cleaned can be controlled by the adjustment member, so that proper cleaning can be performed according to the state of the surface to be cleaned.

That is, when cleaning the surface to be cleaned such as a floor, the user operates the adjusting member so that the cleaning member is not rotated, so that foreign matters on the surface to be cleaned are shaken off by the rotation of the cleaning member to the outside of the suction nozzle. Is prevented.

On the other hand, in the case of cleaning the surface to be cleaned, such as a carpet, the user manipulates the adjusting member to rotate the cleaning member, so that foreign matter adsorbed on the carpet can be easily removed from the carpet and the like to enable a complete cleaning of the surface to be cleaned. do.

In addition, according to the present invention, the adjustment member is rotatably coupled to the suction nozzle, the user is easy to press the operation member by pressing the operation member as the operation portion of the adjustment member is exposed to the upper side of the suction nozzle. Can be manipulated.

In addition, according to the present invention, since the opening and closing member is detachably provided at the lower side of the suction nozzle, the air flow path and the rotating member can be periodically cleaned, so that the rotating member can be smoothly rotated to maintain the cleaning performance. It becomes possible.
