And, the lower side of the nozzle 1 is coupled to the mop plate 50 is attached to the mop for effective cleaning of the bottom surface. The mop plate 50 may be coupled to the base 10 by a plurality of locking members 70.

Therefore, in the case of the nozzle 1 according to the present invention, not only the air containing the dust on the bottom surface can be sucked, but also the bottom surface can be cleaned by the mop.

Hereinafter, each component constituting the nozzle 1 will be described in more detail with reference to the accompanying drawings.

Figure 3 is a perspective view showing the upper appearance of the base according to the invention, Figure 4 is a bottom perspective view of the base, Figure 5 is a bottom perspective view of the cover member according to the invention.

3 to 5, the base 10 forms an outer appearance of the bottom of the nozzle 1, and the cover member 20 is combined with the base 10 to form an upper appearance of the nozzle 1. To form.

In detail, the inlet 102 through which the air containing the dust on the bottom surface is sucked is formed in the center portion of the front end of the base 10. The air sucked through the inlet 102 is guided to the rear of the base 10 by the air guide 60.

At this time, the air guide 60 is formed in a shape having a certain curvature in the cross-section to guide the flow of intake air, as well as to form a smooth curve of the flow of air, which is generated in the process of inhaling air Allow noise to be reduced.

In addition, a pair of lower guide ribs 110 extending upward may be formed on the upper surface of the base 10 to guide the air sucked through the suction port 102 into the pipe holder 30.

That is, the pair of lower guide ribs 110 form a connection flow path 112 through which the air sucked through the inlet 102 moves to the pipe holder 30.

Here, the cover member 20 is formed with an upper guide rib 210 formed in a shape corresponding to the lower guide rib 110, the connection flow path 112 is the lower guide rib 110 and the upper portion. As the guide ribs 210 are combined, they are made completely.

That is, each of the guide ribs 110 and 210 defines a side surface of the connection flow path 112, and the base 10 and the cover member 20 define upper and lower surfaces of the connection flow path 112.

In addition, the guide ribs 110 and 210 are configured to be spaced apart from each other toward the pipe holder 30 from the suction port 102 side.

Here, upper and lower rotation guides 124 and 224 for guiding the up and down rotation of the pipe holder 30 are formed at the rear end of the central portion of the base 10 and the cover member 20, and the guide ribs 110, 210 extends from the suction port 102 side and extends rearward along the sides of the rotation guides 124 and 224.

That is, one portion of the pipe holder 30 is located in the space between the guide ribs 110 and 210.

Therefore, a pair of branch flow paths 113 are formed at the pipe holder 30 side by the configuration of the guide ribs 110 and 210. Each branch flow passage 113 is connected to both sides of the pipe holder 30.

That is, the air sucked through the suction port 102 moves along the connection flow path 112 and branches in both directions while meeting the rotation guides 124 and 224, and then flows into both sides of the pipe holder 30. .

In addition, air introduced to both sides of the pipe holder 30 is combined in the pipe holder 30 and moved to the suction pipe 40. That is, the pipe holder 30 may be regarded as providing a lamination flow passage through which air on the branch flow passage 113 is laminated.

The nozzle 1 of the present invention can be slimmed by being configured to be introduced into both sides of the pipe holder 30 after the air sucked in this way is divided into two flow paths.

That is, in the case of a conventional nozzle, an inlet hole is formed in the front portion of the pipe holder and is configured to suck air moved through a single connection flow path. In this case, when the pipe holder rotates downward, a part of the inlet hole is There was a clogging problem. That is, there is a problem that the suction area is reduced when the pipe holder is rotated downward.

Therefore, in the case of the conventional nozzle, the size of the pipe holder is large in order to prevent some clogging of the inflow hole, but in this case, the nozzle becomes large as a result.

However, in the case of the present invention, inlet holes (see 302 of FIG. 6) are formed at both sides of the pipe holder 30, and the sucked air passes through the pipe holders 30 through the respective inlet holes (see 302 of FIG. 6). ), The cross-sectional area is reduced by half in comparison with the suction area of each inlet hole (refer to 302 of FIG. 6), and as a result, the size of the pipe holder 30, in particular, the upper and lower heights, is reduced. As a result, the nozzle can be made slimmer.

In addition, since the inlet hole (see 302 of FIG. 6) is formed on both sides of the pipe holder 30, even if the pipe holder 30 is rotated, the suction cross-sectional area of the inlet hole (see 302 of FIG. 6) It can be kept constant, and some blockage of the inlet hole 302 of FIG. 6 is prevented.

In addition, since the air is configured to be introduced into the pipe holder 30 through a plurality of paths, the air may be introduced into the pipe holder 30 through the other inlet hole even if one inlet hole is blocked.

Here, the pipe holder 30 is configured to be coupled to the suction pipe 40, otherwise the idea of the present invention may be equally applied even if the pipe holder 30 is integrally formed with the suction pipe 40. There will be.

In addition, the pipe holder 30 and the suction pipe 40 may be connected to the nozzle 1 and the cleaner body regardless of the separation or formation of the pipe holder 30 and the suction pipe 40. Since the pipe holder 30 and the suction pipe 40 are combined, the connection part may be called.

Meanwhile, upper and lower seating ribs 122 and 222 for seating the pipe holder 30 are extended from both ends of the rotation guides 124 and 224 to the rear ends thereof. In addition, the pipe holder 30 is rotatable in a state of being seated on the seating ribs 122 and 222.

In addition, a pair of extensions 140 protruding to the rear side of the base 10 are formed at the rear side of the lower seating rib 122. In addition, a pair of extension cover 240 protruding toward the rear of the cover member 20 to cover the extension 140 is formed at the rear side of the upper seating rib 222.

In detail, the extension part 140 is provided with a moving wheel coupling part 144 to which the moving wheel 92 is coupled.

Meanwhile, a space 130 is formed between the pair of extension parts 140 and the extension part cover 240 to allow the pipe holder 30 to rotate.

That is, the space 130 has three surfaces defined by the rotation guides 124 and 224, the extension 140, and the extension cover 240.

In another aspect, the space 130 may be understood that the rear end of the nozzle 1 is formed by cutting in a shape corresponding to the pipe holder 30. In addition, the nozzle 1 may be viewed as having a rear end penetrating vertically by the space 130. That is, the upper and lower portions of the space part 30 are opened.

In this case, unlike the conventional nozzle, the nozzle of the present invention is no part that interferes with the pipe holder 30 during the lower rotation of the pipe holder 30.

Therefore, the range in which the pipe holder 30 can be rotated downward is increased, so that the thickness of the nozzle 1 is not affected in the state in which the pipe holder 30 is rotated downward. The slimming of 1) can be achieved.

That is, when the pipe holder 30 is rotated downward, the upper side surface of the pipe holder 30 does not protrude upward of the nozzle 1, and thus the nozzle 1 by the pipe holder 30. The increase in the thickness of is prevented, which can be seen as substantially reducing the thickness of the nozzle (1).

Here, since the lower side of the space 130 is open, the pipe holder 30 can be further rotated below the space 130. In this case, when the cleaning is performed by using the nozzle 1, a problem may occur in which the movement of the nozzle 1 may not be smoothly performed by the pipe holder 30.

Therefore, in the present invention, a structure for limiting the range of rotation to the lower side of the pipe holder 30 is provided.

In detail, the anti-rotation protrusion 146 is formed on the inner side of each of the extension parts 140 to prevent the pipe holder 30 from further rotating downward while the pipe holder 30 is rotated at an angle downward. do. The anti-rotation protrusion 146 extends from the inner surface of the extension part 140 toward the space 130.

Thus, the pipe holder 30 is stopped by the anti-rotation protrusion 146 while being rotated downward.

Here, the pipe holder 30 completely fills the space 130 in a completely rotated downward direction, and the anti-rotation protrusion 146 supports the lower side of the pipe holder 30. Can be.

Therefore, from a functional point of view, the anti-rotation protrusion 146 may be referred to as a support for supporting the pipe holder 30 in a state in which the pipe holder 30 is rotated downward.

On the other hand, a plurality of fastening holes 164 through which a fastening member (not shown) is formed to be coupled to the cover member 20 in the base 10, and the fastening member and the fastening member are fastened to the cover member 20. A plurality of fastening bosses 206 are formed to be. In addition, the cover member 20 is provided with a plurality of reinforcing ribs 208 for improving the strength of the cover member 20.

On the other hand, the lower side of the base 10 is formed with a plate seating portion 160 on which the mop plate 50 may be seated, and the plate seating part 160 is guided to seat the mop plate 50. A plurality of seating guide portion 162 is formed.

In addition, the base 10 is formed with a plurality of coupling parts 150 to which the locking member 70 is coupled to fix the mop plate 50 in a state in which the mop plate 50 is seated on the plate seating part 160.

In detail, the coupling part 150 includes a locking end 152 for fixing the locking member 70, and a portion of the locking member 70 protrudes to the plate seating part 160 to provide the mop plate 50. ) Is formed with a through hole 156 to enable coupling with the support end 154 to support the lower side of the locking member 70.

Therefore, when the rag plate 50 is seated on the plate seating portion 160 in a state in which the catching member 70 is coupled to the coupling part 150, the catching member 70 and the rag plate 50 are provided. The locking action of) is performed so that the mop plate 50 is fixed to the nozzle 1. The locking structure of the mop plate 50 and the locking member 70 will be described later with reference to the drawings.

Figure 6 is a perspective view of a pipe holder according to the present invention, Figure 7 is a bottom perspective view of a nozzle showing a state that the pipe holder is rotated completely downward.

6 and 7, the pipe holder 30 according to the present invention is a portion for allowing the up and down rotation of the suction pipe 40, and the air on the connection flow path 112 is the suction pipe 40. To be delivered to.

In detail, inflow holes 302 through which air on the branch flow passage 113 flows are formed at both side surfaces of the pipe holder 30. Therefore, the air sucked through the suction port 102 is sucked into the pipe holder 30 through both side surfaces of the pipe holder 30 through the connection flow path 112 and the branch flow path 114. As described above, slimming of the nozzle 1 can be achieved by the pipe holder 30 constituting such a configuration.

At this time, the center of the inlet hole 302 is coincided with the axis of rotation of the pipe holder 30. In this case, despite the vertical rotation of the pipe holder 30 it is possible to maintain a constant suction cross-sectional area.

In addition, the pipe holder 30 is provided with a connection portion 304 connected to the suction pipe 40, and a projection insertion groove 306 into which the anti-rotation protrusion 146 is inserted is recessed in a bottom surface thereof.

Therefore, when the pipe holder 30 is rotated downward and the anti-rotation protrusion 146 is inserted into the protrusion insertion groove 306, the pipe holder 30 is no longer rotated downward.

Here, the anti-rotation protrusion 146 is formed at the inner lower end of the extension 140. In this case, when the pipe holder 30 is completely rotated downward, the bottom surface of the pipe holder 30 is substantially horizontal with the bottom surface.

In addition, as described above, since the lower side of the space 130 is open, when the pipe holder 30 is rotated downward, the bottom surface of the pipe holder 30 may partially remove the bottom surface of the nozzle 1. To form.

In addition, a step portion 309 is formed below the pipe holder 30 to be stepped inward.

In detail, the stepped portion 309 serves to prevent interference between the pipe holder 30 and the mop plate 50 when the pipe holder 30 rotates downward. The stepped portion 309 is in contact with the upper surface of the mop plate 50 when the pipe holder 30 rotates downward.

Here, the pipe holder 30 is no longer rotated downward when the step portion 309 is in contact with the upper surface of the mop plate 50 when the pipe holder 30 rotates downward.

That is, according to the present invention, the lower side of the pipe holder 30 by the relationship between the step portion 309 and the mop plate 50 and the relationship between the anti-rotation protrusion 146 and the projection insertion groove 306. Directional rotation limits are determined.

Hereinafter, the operation of the nozzle 1 according to the present invention will be described.

8 is a cross-sectional view of the nozzle according to the present invention, Figure 9 is a view showing the air flow inside the nozzle according to the present invention.

8 and 9, when the cleaner body to which the nozzle 1 is connected is operated, suction force is generated by the suction force generating means provided in the cleaner body, and thus dust on the bottom surface of the floor through the suction port 102. Air containing is inhaled.

In addition, the air sucked through the suction port 102 is guided by the air guide 60 and moved to the connection flow path 112. In addition, the air moved to the connection flow path 112 is branched and moved along the branch flow path 113, and then inside the pipe holder 30 through the inlet hole 302 on both sides of the pipe holder 30. Flows into.

As described above, the pipe holder 30 is rotated up and down while the air is sucked, and in this case, the suction cross-sectional area where the air is sucked into the pipe holder 30 remains the same.

In addition, the air introduced from both sides of the pipe holder 30 is combined in the pipe holder 30 and finally moved to the cleaner body through the suction pipe 40.

According to the present invention as proposed, the suctioned air is divided into two flow paths and as the air flowing through each flow path is introduced into the pipe holder through both sides of the pipe holder, the air sucked into the pipe holder Suction cross-sectional area can be given in half compared to the prior art has the effect that the nozzle can be made slim.

In addition, since the inlet hole through which air can be introduced is formed at both sides of the pipe holder, the suction cross-sectional area of the air can be kept constant when the pipe holder is rotated, thereby enabling smooth intake of air.

In addition, the portion that interferes with the pipe holder is removed, so that the thickness of the nozzle is prevented from being increased by the pipe holder as it is positioned substantially parallel to the bottom surface during the lower rotation of the pipe holder. This has the effect of reducing the thickness compared to the conventional nozzle.

In addition, by slimming the nozzle, it is possible to clean a narrow gap such as a sofa or a furniture, to reduce the weight of the nozzle, and to reduce the manufacturing cost of the nozzle.
