BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nozzle of a cleaner, and more particularly, to a nozzle that is slimmed down by structural improvement of a pipe holder.

In general, the vacuum cleaner is a device that sucks air containing foreign matters such as dust and the like by using a vacuum pressure generated by the suction force generating means provided in the main body, and then filters the foreign matters inside the main body.

Such a cleaner is connected to a suction nozzle that is movable along the bottom surface to allow the air containing dust to be sucked. That is, the user cleans the bottom surface while moving the suction nozzle in the front-rear direction.

When cleaning using the suction nozzle as described above, there is no problem when cleaning the floor, but in the case of a narrow gap such as the bottom of the sofa, the cleaning cannot be performed using the nozzle. In this case, the user should clean the device using a tool other than the nozzle.

Therefore, a nozzle for smoothly cleaning the narrow gap is required.

In addition, when a large foreign matter such as a tissue among the sucked dust is not moved to the suction pipe and caught in the nozzle, there is a problem in that the foreign matter is removed after disassembling the nozzle.

Therefore, there is a need for a nozzle that allows a user to easily remove foreign substances inside the nozzle.

The present invention has been proposed under the background as described above, and an object of the present invention is to propose a nozzle of a cleaner that can be slimmed down by an improvement in the structure of a pipe holder and can be easily cleaned in a narrow gap.

In addition, an object of the present invention is to propose a nozzle of a cleaner which can easily remove the foreign matter inside the nozzle.

In addition, an object of the present invention is to propose a nozzle of a cleaner to improve the structure of the flow path, to enable the smooth suction of air containing dust.

The nozzle of the cleaner according to the present invention for achieving the object as described above is a nozzle body is formed inlet; A flow path through which the air sucked through the suction port flows; A connection part formed with an inlet hole through which air moved through the flow path is introduced; And an anti-rotation member formed in the nozzle body and configured to set at least a lower rotation limit of the connecting portion.

According to another aspect of the present invention, a nozzle of a cleaner includes: a nozzle body through which air is sucked; A connection part rotatably provided in the nozzle body, into which air sucked into the nozzle body flows; A first limit setting unit formed on the connection unit and configured to set upper and lower rotational limits of the connection unit; And a second limit setting unit formed in the main body and working with the first limit setting unit.

According to yet another aspect, a nozzle of a cleaner of the present invention includes a nozzle body in which an air inlet is formed; A connecting portion coupled to the nozzle body; A connection flow path through which the air sucked through the suction port flows; A branch passage branched in at least two directions from the connection passage to communicate with the connection portion; At least one opening formed in the nozzle body to remove foreign substances on the flow path; And a foreign material removing cover for selectively opening the opening.

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.

1 is a perspective view of a cleaner nozzle according to the present invention, Figure 2 is an exploded perspective view of the nozzle.

1 and 2, the nozzle 1 according to the present invention is formed by a base 10 forming a bottom appearance and a cover member 20 coupled to an upper side of the base 10. .

In addition, the nozzle 1 has a pipe holder 30 through which air moved to the rear side of the nozzle 1 is introduced, one side is coupled to the pipe holder 30, and the other side is connected to a cleaner body (not shown). Included is a suction pipe 40 coupled with a connected extension tube (not shown).

In addition, the nozzle 1 is provided with a plurality of moving wheels 96 to enable the movement of the nozzle 1 at the rear lower end, and a plurality of auxiliary wheels to assist the movement of the nozzle 1 at the front lower end. 98 is provided.

The front end of the nozzle 1 is provided with a bumper 80 that protects the nozzle 1 from external impact. In this case, the bumper 80 may have an elastic material for effective protection of the nozzle 1.

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. Air sucked through the inlet 102 is guided to the rear of the base 10.

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 formed in a straight line such that a distance from the suction port 102 side to the pipe holder 30 side is constant. By this shape, the size of the flow path increases, so that the sucked air can flow smoothly.

Here, at the rear end of the central portion of the base 10 and the cover member 20, upper and lower rotation guides 224 and 124 are formed to guide the vertical rotation of the pipe holder 30, 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.

Here, the base 10 is formed with an opening 114 for removing the foreign matter remaining on the branch flow path (113). This is because the branching flow path 113 formed on both sides is small because the suction force is lowered when foreign matter remains, it is necessary to remove it.

That is, a portion of the branch flow passage 113 is opened to form the opening 114 and is selectively opened and closed by a foreign matter removing cover (to be described later). Therefore, the user may clean the foreign matter removing cover in a closed (coupled) state and remove the foreign matter by separating the foreign matter removing cover when it is necessary to remove the foreign matter.

On the other hand, since the guide ribs 110 and 210 are provided in a straight line such that the distance from the suction port 102 side to the pipe holder 30 is constant, the width of the connection flow path 112 can be increased. In addition, when the width of the branch flow passage 113 can be largely secured, the jam of the foreign matter is minimized and the movement of air into the pipe holder 30 can be smoothly performed.

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 formed large in order to prevent some clogging of the inflow hole, but in this case, the nozzle becomes large as a result.

However, according to the present invention, inlet holes (see 302 in FIG. 9) 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 in FIG. 9). ), The cross-sectional area is reduced by half in comparison with the suction area of each inlet hole (see 302 of FIG. 9), and consequently the size of the pipe holder 30 is reduced, in particular, the height of the upper and lower sides. As a result, the nozzle can be made slimmer.

In addition, since the inlet hole (see 302 of FIG. 9) 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. 9) is constant. Can be maintained, and some blockage of the inlet hole 302 of FIG. 9 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.

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 integral formation of the pipe holder 30 and the suction pipe 40. As it serves, the pipe holder 30 and the suction pipe 40 may be referred to as a joint portion.

Meanwhile, the lower seating rib 122 and the upper seating rib 222 for the pipe holder 30 to be seated are extended from both end portions 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 rotation preventing member 127 is provided between the lower seating ribs 122. Here, the anti-rotation member 127 is extended and formed with a constant curvature in the lower seating rib 122 within the rotatable range of the pipe holder 30.

That is, the anti-rotation member 127 forms a partial appearance of the bottom surface of the base 10 and covers a portion where the pipe holder 30 is rotated.

When the pipe holder 30 is rotated downward by a predetermined angle, the pipe holder 30 is in contact with the rotation preventing member 127. Then, the pipe holder 30 can no longer be rotated. That is, the rotation preventing member 127 may be regarded as setting the lower rotation limit of the pipe holder 30. In addition, in another aspect, the anti-rotation member 127 may be viewed as supporting the lower side of the pipe holder 30.

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 addition, the moving wheel 96 is coupled to the extension 140.

Meanwhile, a space 130 is formed between the rear side of the anti-rotation member 127 and the pair of extension parts 140 and the extension part cover 240 to allow the pipe holder 30 to rotate. do. That is, the space 130 has three surfaces defined by the rotation preventing member 127, 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.

Therefore, the range in which the pipe holder 30 can be rotated 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, so that the nozzle 1 The slimming of 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).

Meanwhile, the base 10 has a plurality of fastening holes 161 through which a fastening member (not shown) penetrates to be coupled to the cover member 20, and the fastening member and the fastening member are fastened to the cover member 20. A plurality of fastening bosses 260 are formed.

In addition, a plurality of reinforcing ribs 170 and 270 are formed in each of the base 10 and the cover member 20 to improve the strength of the nozzle against external impact.

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 plate seating holes 166 are 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 so that the mop plate ( A through hole 154 is formed to allow engagement with 50.

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.

Meanwhile, the lower rotation preventing end 128 is formed on the rear side of the lower rotation guide 124 and the upper rotation preventing end 228 is formed on the rear side of the upper rotation guide 224.

Here, the lower anti-rotation end 128 is a portion to which the lower side of the anti-rotation protrusion (to be described later) of the pipe holder 30 comes into contact when the pipe holder 30 is rotated upward by a predetermined angle. The holder 30 can no longer be rotated upwards.

On the other hand, the upper anti-rotation end 228 is a portion in which the upper side of the anti-rotation protrusion (described later) of the pipe holder 30 is in contact with the pipe holder 30 when the pipe holder 30 is rotated downward. ) Can no longer be rotated downwards.

That is, the anti-rotation stages 128 and 228 allow the upper and lower rotation limits of the pipe holder 30 to be set, and thus, the anti-rotation protrusions may be set as the first limit setting unit, and the anti-rotation stages 128 and 228 may be removed. 2 may be referred to as the limit setting unit.

In addition, the width of the anti-rotation stages 128 and 228 is preferably such that the anti-rotation protrusion (described later) of the pipe holder 30 can be inserted. The operation of the anti-rotation stages 128 and 228 and the anti-rotation protrusion will be described later with reference to the drawings.

On the other hand, the bottom surface of the base 10 has a rib engaging end 162 and the cover support hole 164 is formed so that the foreign matter removal cover (to be described later) is detachable from both sides. The principle that the foreign matter removing cover is detached from the base 10 will be described below with reference to the drawings.

Figure 6 is a perspective view of the foreign material removal cover according to the present invention, Figure 7 is a bottom perspective view of the foreign material removal cover according to the present invention, Figure 8 is a bottom perspective view of the nozzle showing a state in which the foreign material removal cover is coupled.

6 to 8, the debris removal cover 90 has a detachable handle 91 formed at a central portion thereof, and both sides of the debris removing cover 90 are supported with a locking rib 92 so that the debris removing cover 90 is detachable. Ribs 94 are formed respectively.

In detail, a support rib 94 is formed below the foreign material removing cover 90 so that the foreign material removing cover 90 can be easily mounted to the base 10. In addition, a cover support hole 164 is recessed in the bottom surface of the base 10 so that the support rib 94 may be coupled thereto.

In addition, the locking ribs 92 extend from the lower side of the foreign material removal cover 90 to be formed in a "V" shape, and the end of the locking ribs 92 is formed in a bent shape. The bottom surface of the base 10 is provided with a rib locking end 162 to which the locking rib 92 can be caught.

In order to couple the foreign material removing cover 90 to the base, the support rib 94 is first inserted into the cover support hole 164, and then the locking rib 92 is connected to the rib locking end 162. Insert it downward to catch. Then, the bent end of the locking rib 92 is caught by the rib locking end 162.

Then, in order to remove the foreign matter removing cover 90 from the base, the end of the locking rib 92 is pressed by the inner side of the foreign matter removing cover 90 and lifted up. Then, the support rib 94 is removed from the cover support hole 164. In this case, it is preferable that an elastic material is used for the locking ribs 92 so that the locking ribs 92 can be easily removed.

In addition, inserting members 93 are provided at both sides of the foreign material removing cover 90, and when the foreign material removing cover 90 is coupled to the base 10, the insertion member 93 is disposed at the opening 114. Is inserted. Then, air may be prevented from leaking through the opening 114.

Therefore, when the foreign matter removal cover 90 is coupled to the cleaning state, and a large foreign material such as a tissue is caught in the basin flow passage 113, the user removes the foreign material removal cover 90 to remove the foreign material. It can be removed.

9 is a perspective view of a pipe holder according to the present invention, FIG. 10 is a perspective view of a base in which the pipe holder is coupled, and FIG. 11 is a sectional view of a nozzle showing a state in which the pipe holder is completely rotated downward. 12 is a cross-sectional view of the nozzle showing a state in which the pipe holder is completely rotated upwards.

9 to 12, the pipe holder 30 according to the present invention is a portion that enables the vertical 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 113. 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 coincides with the rotation axis 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 connected to the suction pipe 40 at the rear side, and the anti-rotation protrusion 306 is formed on the front side.

In detail, the upper surface of the anti-rotation protrusion 306 is formed horizontally in the "U" shape as the upper locking portion 310. The front surface extends in the vertical direction and the bottom surface is formed by the lower end engaging portion 308, which is inclined at a predetermined angle from the front side to the rear side.

Therefore, as shown in FIG. 11, when the pipe holder 30 is rotated downward by a predetermined angle, the upper locking portion 310 of the anti-rotation protrusion 306 is in contact with the upper anti-rotation end 228. Then, the pipe holder 30 is no longer rotated downward. Here, as described above, the lower rotation of the pipe holder 30 may be limited by the rotation preventing member 127.

In addition, when the pipe holder 30 is rotated upward by a predetermined angle as shown in FIG. 12, the lower end locking portion 308 of the anti-rotation protrusion 306 contacts the lower anti-rotation end 128. Then, the pipe holder 30 is no longer rotated upwards.

On the other hand, a stepped portion 309 is formed on the lower side of 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 rotation preventing member 127 when the pipe holder 30 rotates downward. The stepped portion 309 is in contact with the top surface of the anti-rotation member 127 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 anti-rotation member 127 when the pipe holder 30 rotates downward.

That is, according to the present invention, the relationship between the stepped portion 309 and the anti-rotation member 127 and the anti-rotation protrusion 306 and the anti-rotation ends 128 and 228 prevents the pipe holder 30. Lower and upper rotational limits are determined.

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

13 is a view showing the air flow inside the nozzle according to the present invention.

Referring to FIG. 13, 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 surface to be cleaned is included through the suction port 102. Air is inhaled.

In addition, the air sucked through the suction port 102 is moved to the connection flow path 112. Then, the air moved to the connection flow path 112 is branched and moved along the branch flow path 113, and then through the inlet hole 302 on both sides of the pipe holder 30, the pipe holder 30 It flows inside.

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, air introduced to 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, a projection is formed on the front surface of the pipe holder, the anti-rotation end is formed on the base and the cover member so that the protrusion is in contact with the anti-rotation end to limit the vertical rotation range of the pipe holder nozzle It is effective to slim down.

In addition, as the width of the flow path through which the sucked air is moved is widened, the air flow is good, so that foreign matters are caught in the inlet hole of the pipe holder.

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 during the rotation of the pipe holder, thereby enabling smooth intake of air.

In addition, when the foreign matter removal cover is provided on the bottom surface of the base, when the foreign material is caught in the inlet hole of the pipe holder, the user can remove the foreign matter by removing the cover without disassembling the entire nozzle.

On the other hand, as the suctioned air is divided into two flow paths and the air flowing through each flow path is introduced into the pipe holder through both sides of the pipe holder, the suction cross-sectional area of the air sucked into the pipe holder is less than half It can be given to the effect that can be made slimmer nozzle.
