Description
Technical Field
The present invention relates to a suction member for sucking dust and an electric cleaner using the same.
Background
A conventional general electric vacuum cleaner includes: a hose connected to the electric cleaner main body; a handle operation part connected to the hose; an extension pipe connected to the handle operation part; and a suction nozzle connected to the extension pipe.
However, the suction nozzle of the conventional electric vacuum cleaner having such a structure is relatively large, and thus, the suction nozzle is not suitable for sucking dust at a high level, such as on a cabinet.
As a technique for solving such a problem, for example, patent document 1 (japanese patent application laid-open No. 2010-99165) discloses a vacuum cleaner of such a type: by installing the connection part at the top end of the extension pipe and installing the brush holder with the brush which can rotate by the shaft at the top end of the connection part, dust can be easily collected even in a high place by rotating the small-sized brush.
However, in the technique described in patent document 1, although the brush is rotatable, when dust in the deep part of the upper surface of the cabinet which is high and cannot be reached by the hand is collected, since the extension pipe provided between the handle operation portion and the brush is straight, there is a problem as follows: after the straight extension pipe is abutted against the upper edge of the cabinet, the brush is in a suspended state, so that the brush cannot reach the deep surface of the upper surface of the cabinet.
Disclosure of Invention
The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a suction tool in which a joint portion of the suction tool can be bent at a large rotation angle, so that dust can be collected even in a narrow place or a deep place such as a deep place on an upper surface of a high cabinet where a hand cannot reach, and the bent portion of the bent joint portion can be prevented from being caught by a user's finger, and a vacuum cleaner using the suction tool.
Specifically, the present invention provides a suction member and an electric vacuum cleaner using the same, the suction member including: a connecting tube portion which is capable of expansion and contraction; a joint part having a plurality of rotating parts, the joint part being connected to the connecting pipe part; and a suction head connected to the joint portion in a manner rotatable with respect to the joint portion, wherein each of the plurality of rotation portions has a convex portion and a bottom groove portion. The joint portion is configured as follows: the plurality of rotating portions are connected to each other by the shaft portion, and the convex portion is inserted into a bottom groove portion of a rotating portion to be connected among the plurality of rotating portions.
Thus, the joint part can be bent at a large rotation angle, and the suction head can be extended to a deep position on the upper surface of the cabinet where the hand cannot reach and cleaned. Further, the fingers of the user can be prevented from being caught by the portion where the gap is generated in the bent portion of the joint portion.

In fig. 1, a cleaner body 1 of an electric vacuum cleaner 100 has an electric blower for generating suction air and a dust collecting part. One end of the hose 2 is connected to the cleaner body 1 via a hose connector 3, and is further communicated with the dust collecting part.
One end of the grip handle 4 is connected to the hose 2, and the other end of the grip handle 4 is connected to the extension pipe 5. The extension pipe 5 is of a structure capable of freely extending and contracting. A suction nozzle 6 is connected to the top end of the extension pipe 5, and when the user turns on the electric vacuum cleaner 100, the electric blower inside the cleaner body 1 is driven to generate suction air from the suction inlet of the suction nozzle 6, thereby sucking dust attached to a floor surface or the like, and collecting the dust in the dust collecting part inside the cleaner body 1 via the extension pipe 5, the handgrip part 4, and the hose 2.
The extension pipe 5 is detachably provided to the grip handle 4, and dust can be sucked from the opening of the grip handle 4 in a state where the extension pipe 5 is detached from the grip handle 4. In addition, dust can be sucked from the opening portion of the extension pipe 5 in a state where the suction nozzle 6 is detached from the extension pipe 5.
Fig. 2 is an external perspective view of the suction material 7 according to the embodiment of the present invention, as viewed from above. The suction piece 7 may be attached to the grip handle portion 4 in place of the extension pipe 5, and the suction piece 7 may be attached to the extension pipe 5 in place of the suction nozzle 6.
As shown in fig. 2, the suction tool 7 according to the embodiment of the present invention includes a connecting tube portion 8, a joint portion 9, and a suction head 12. The connecting tube portion 8 can be extended and contracted in the direction in which the suction member 7 extends. The connection tube portion 8 can be extended and retracted by the user pressing the operation button 20. On the other hand, in a state where the user does not press the operation button 20, the connecting tube portion 8 cannot be expanded and contracted, and the length of the connecting tube portion 8 at present is maintained.
The joint 9 includes a plurality of turning portions 11 described later, and the joint 9 can be bent in stages. The structure and bending operation of the joint 9 will be described in detail later.
A suction head 12 is connected to the distal end of the joint portion 9, and as shown in fig. 2, an axis a (an axis in a direction perpendicular to the direction in which the connecting tube portion 8 extends in the state shown in fig. 2) as a shaft portion is provided at a connecting portion between the distal end of the joint portion 9 and the suction head 12, and the suction head 12 is rotatable in the direction of arrow B-B' shown in fig. 2 with the axis a as the shaft portion as a rotation axis.
Further, the suction head 12 can rotate in the direction of arrow C-C' in fig. 2 with respect to the joint 9. That is, the suction head 12 can be rotated clockwise or counterclockwise in the state of fig. 2 with the direction in which the connecting tube portion 8 extends as the axial direction.
The rotation direction of the suction head 12 is not limited to the above rotation direction, and the suction head 12 can be rotated in a desired rotation direction by changing the shape, position, and the like of a shaft portion provided at a connecting portion between the joint portion 9 and the suction head 12.
A light emitting section 13 is formed at the tip of the suction head 12. The housing of the light emitting section 13 is made of transparent resin or the like so as to allow light to be emitted to the outside. Further, a semiconductor light Emitting element such as an LED (light Emitting diode) is disposed inside the light Emitting section 13, and light from the LED or the like can be emitted to the outside.
A switch operation unit 14 for turning on or off the LED is formed on the upper portion of the suction head 12, and the user can turn on or off the LED by sliding the switch operation unit 14.
Fig. 3 is an exploded perspective view of the connecting tube portion 8, and fig. 4 is an enlarged sectional view of the connecting tube portion 8 in the vicinity of the operation button 20. As shown in fig. 3, a cap 16 is fitted over one end of the outer extension pipe 15, and an inner extension pipe 18 is inserted into the other end of the outer extension pipe 15 via a stopper 17. Further, a 1 st opening 19 is formed in a lower portion of the outer extension pipe 15.
As shown in fig. 4, a 1 st projection 21 projecting inward is formed inside the operation button 20, the 1 st projection 21 is formed integrally with the operation button 20, and a spring 22 is fitted around the 1 st projection 21. A 1 st locking portion 23 is attached to one end of the operation button 20, and the 1 st locking portion 23 is disposed so as to be accommodated in a 1 st opening 19 provided in a lower portion of the outer extension pipe 15.
The 1 st locking portion 23 is locked to any one of the 1 st groove portions 24 formed in the inner extension pipe 18, whereby the sliding of the inner extension pipe 18 with respect to the outer extension pipe 15 can be restricted.
Further, a 2 nd projection 26 of the locking plate 25 is disposed at a position facing the 1 st projection 21 of the operation button 20. The spring 22 is also fitted around the 2 nd protrusion 26, and the spring 22 is inserted between the 1 st protrusion 21 and the 2 nd protrusion 26.
Generally, the operation button 20 is applied with a downward force in fig. 4 and the 1 st locking portion 23 is applied with an upward force in fig. 4 by the elastic force of the spring 22. Therefore, the 1 st locking portion 23 can be locked in the 1 st groove portion 24, and the sliding of the inner extension pipe 18 with respect to the outer extension pipe 15 can be restricted.
When the user presses the operation button 20, the operation button 20 is pressed upward in fig. 4 against the urging force of the spring 22, and the 1 st locking portion 23 moves downward in fig. 4 in association therewith, whereby the locking of the 1 st locking portion 23 to the 1 st groove portion 24 can be released. In this way, the inner extension pipe 18 can slide with respect to the outer extension pipe 15.
Fig. 5 is an exploded perspective view of the joint 9. The joint 9 has a plurality of rotating portions 11 and a fixed portion 10. In the present embodiment, the joint portion 9 includes 3 rotating portions 11 and one fixed portion 10. The rotating portion 11 is provided with a pair of substantially circular 3 rd protrusions 27 on the side surface of the portion toward the front (the side closer to the suction head 12), a pair of substantially circular 1 st holes 28 on the side surface of the portion toward the rear (the side closer to the connecting tube portion 8), and a notch 30 on the portion toward the rear (the side closer to the connecting tube portion 8) of the rotating portion 11.
The 3 rd protrusion 27 of the rotary part 11 can be inserted into the 1 st hole 28 of the adjacent rotary part 11. By inserting the 3 rd projection 27 into the 1 st hole 28, the rotating part 11 can be rotated about 30 degrees in the D direction in fig. 5 (the direction perpendicular to the direction in which the joint part 9 having the plurality of rotating parts 11 extends) with the axis B as a crankshaft (the portion closer to the suction head 12 side) of the rotating part 11 as shown in fig. 5.
Note that the angle of about 30 degrees means that the adjacent turning portions 11 can be turned by about 30 degrees, and for example, when 3 turning portions 11 are connected as in the present embodiment, the cumulative total of the turning angles from the first turning portion 11 to the 3 rd turning portion 11 can be turned by about 90 degrees. That is, the coupled rotating portions 11 can rotate by about 90 degrees with respect to the fixed portion 10. When 5 rotating units 11 are coupled, the whole of the coupled rotating units 11 can rotate by about 150 degrees with respect to the fixed unit 10.
In a state where the rotation angle between the rotating portions 11 is about 0 degree, as will be described later, all the rotating portions 11 do not rotate, but adjacent rotating portions 11 are positioned substantially on the same straight line as each other and the joint portions 9 extend substantially on the same straight line as shown in fig. 7.
An inclined surface 29 inclined downward from the rear of the rotating portion 11 (toward the connecting pipe portion 8) toward the front (toward the suction head 12) is formed near the upper side of the 3 rd projection 27 toward the front (toward the suction head 12) of the rotating portion 11. On the other hand, a notch 30 that expands from the rear of the rotating portion 11 toward the front is formed near the upper side of the 1 st hole portion 28 in the rear of the rotating portion 11 (on the side of the connecting pipe portion 8).
Fig. 6 is a perspective view of the connecting portion of the rotating portions 11 to be connected in an enlarged manner. Two grooves, an upper groove 31 and a lower groove 32, are formed inside the side surface of the portion of the rotating portion 11 toward the rear (toward the connecting pipe portion 8). On the other hand, a projection (japanese: ノッチ)33 is formed on the outer side of the side surface of the portion of the rotating section 11 in front (on the suction head 12 side).
The upper groove 31 and the lower groove 32 are each formed in a substantially triangular shape in which the width of the groove gradually decreases from the rear to the front of the rotating portion 11, and one of the substantially triangular shapes of the upper groove 31 and the lower groove 32 is formed parallel to the direction in which the joint portion 9 having the plurality of rotating portions 11 extends. The upper groove 31 and the lower groove 32 have a symmetrical shape as if the upper groove 31 and the lower groove 32 were mirror-symmetrical about one side of a substantially triangular shape (tube axis direction) parallel to the direction in which the joint portion 9 having the plurality of rotating portions 11 extends.
On the other hand, the projection 33 has a substantially triangular shape gradually widening from the front to the rear of the rotating portion 11.
By fitting the projection 33 into the upper groove 31 or the lower groove 32, it is possible to prevent play between the fitted rotating portions 11 to such an extent that the cleaning operation is hindered. However, a slight gap may be formed between the lower groove 32 or the upper groove 31 and the projection 33, and slight play may be allowed to occur by the gap to such an extent that the cleaning operation is not hindered.
In the state where the projection 33 is fitted into the upper groove 31, the rotation angle between the rotating portions 11 fitted to each other is substantially 0 degree, and the pipe axes of the rotating portions 11 fitted to each other extend in the same direction.
Here, a description will be given of a structure in which the projection 33 can be selectively fitted into the groove portions 31 and 32, and a structure in which the plurality of turning portions 11 can be turned at different turning angles from each other and can hold the turning angles.
When the rotating part 11 is rotated by a predetermined angle or more in a state where the projection 33 is fitted into the upper groove 31, the projection 33 fitted into the upper groove 31 moves over the boundary between the upper groove 31 and the lower groove 32 by the elastic force of the resin of the rotating part 11 and is fitted into the lower groove 32, because the rotating part 11 is formed of the resin. When the rotating part 11 is rotated by a predetermined angle or more in a state where the projection 33 is fitted into the lower groove 32, the projection 33 moves over the boundary between the lower groove 32 and the upper groove 31 and is fitted into the upper groove 31. By such an operation, the projection 33 can be selectively fitted into the two or more groove portions 31, 32, and the rotated angle can be maintained.
The rotation angle is not limited to about 30 degrees, and may be set to 30 degrees or more or less depending on the shape of the projection 33, the shape of the groove portion, and the number of groove portions.
The rotation angles of the plurality of rotation portions 11 are not necessarily the same angle (for example, about 30 degrees), and the plurality of rotation portions 11 can rotate at different rotation angles depending on the shapes of the protrusion 33 and the grooves 31 and 32 and the number of grooves.
In the present embodiment, the groove portion is provided with two grooves, i.e., the upper groove 31 and the lower groove 32, but the number of the groove portions is not limited to two, and may be 3 or more. However, when the number of the groove portions is increased, the angle can be set more finely, but on the other hand, the turning portion 11 is increased in size to weaken the holding force of the joint, and therefore, the total number of the upper grooves 31 and the lower grooves 32 is preferably 2 to 8.
Fig. 7 is a perspective view of the joint 9 with the suction head 12 attached thereto, as viewed from below.
As shown in fig. 7, a 3-step bottom groove portion 34 is formed in a portion of the rotating portion 11 on the lower side toward the rear (toward the connecting pipe portion 8). On the other hand, a 3-way convex portion 35 is formed at a lower portion of the rotating portion 11 in the front direction (the suction head 12 side). The convex portion 35 and the bottom groove portion 34 are arranged so that the 3 convex portions 35 can be inserted into the 3 bottom groove portions 34, respectively.
Fig. 8 is a perspective view showing a state in which the joint 9 is bent. The joint portion 9 can be bent by rotating each of the plurality of rotating portions 11 constituting the joint portion 9. As described above, each of the rotating portions 11 can be rotated by about 30 degrees, and therefore, in the configuration of fig. 8 in which 3 rotating portions 11 are coupled, the joint portion 9 can be rotated by about 90 degrees as a whole.
As described above, since each of the plurality of rotating portions 11 provided in the joint portion 9 is configured to be rotatable, the joint portion 9 is configured to be bendable in multiple stages. The joint 9 is configured such that: the bending angle of the joint 9 can be finely adjusted according to the number of the rotating portions 11 provided in the joint 9 and the size of the rotating angle of each rotating portion 11.
A fur brush 36 is formed at the lower portion of the suction head 12, and a suction port 41 is formed at the lower portion of the suction head 12 so as to be surrounded by the fur brush 36. The dust wiped down by the brush 36 can be sucked through the suction port 41 and fed into the dust collecting chamber of the cleaner body 1.
The plurality of rotating portions 11 are connected to each other so as to be fitted to each other as described above. In a state where the rotation angle between the adjacent rotating portions 11 is about 0 degrees and the respective rotating portions 11 do not rotate, that is, in a state where the adjacent rotating portions 11 are positioned on substantially the same straight line and the joint portion 9 extends straight as shown in fig. 7, the convex portion 35 is inserted into the deepest portion of the bottom groove portion 34, and a state where one rotating portion 11 is embedded in the rotating portion 11 to be fitted thereto or a state where the one rotating portion 11 is positioned on the same plane as the other rotating portion 11 to be fitted thereto is obtained.
When the adjacent turning sections 11 are formed so as to be straight on substantially the same straight line, the convex section 35 does not protrude outward, and therefore, the user does not feel uncomfortable because the convex section 35 does not hit the hand when holding the turning section 11.
In this case, the convex portion 35 may be protruded outward to such an extent that the user's finger does not feel uncomfortable.
Next, when the rotating parts 11 are rotated to bend the joint part 9 in this state, as shown in fig. 8, a part of the convex part 35 of one rotating part 11 of the rotating parts 11 connected to each other protrudes outward from the bottom groove part 34 of the other rotating part 11.
Further, the portion of the convex portion 35 protruding outward partially closes the gap 42 formed by the valley-shaped bent portion between the rotating portions 11 in association with the rotation, and thereby the human fingers can be prevented from entering the gap 42.
Therefore, with such a configuration, not only the rotation angle of the rotating portion 11 can be increased, but also the fingers of the user can be prevented from being caught by the gap 42 portion generated between the rotating portions 11 when the rotating portions 11 are rotated.
Fig. 9 is a side view of the suction piece 7 in a state where the joint portion 9 is bent by about 90 degrees.
As shown in fig. 9, when only the first rotating portion 11 is bent, the joint portion 9 is bent by about 30 degrees, when the second rotating portion 11 is further bent, the joint portion 9 is bent by about 60 degrees, and when the third rotating portion 11 is further bent, the joint portion 9 is bent by about 90 degrees. Even in the state where the bending angle of the joint 9 is increased in this way, the above-described structure does not generate a backlash between the rotating portions 11 of the joint 9 to such an extent that the cleaning operation is hindered. Thus, even in a state where the bending angle of the joint 9 is increased, the suction head 12 of the suction tool 7 can be extended deep into the ceiling surface of the cabinet, the ceiling surface of the air conditioning indoor unit, and the like, and a position which is difficult to clean up to now and is not reached by a hand can be cleaned.
The number of the rotating portions 11 is not limited to 3, and more rotating portions 11 may be provided. By increasing the number of the rotating portions 11, the angle at which the joint portion 9 can be bent can be further increased, and the joint portion 9 can be changed to a desired shape and used. On the other hand, since the number of the rotating portions 11 is increased, there is a disadvantage that the joint portion 9 becomes too large and heavy or too long. Therefore, the number of the rotating portions 11 is preferably 2 to 8, and the angle at which one rotating portion 11 can be bent is preferably 5 to 40 degrees. When the bending angle is excessively increased, fine angle adjustment cannot be performed, and when the bending angle is excessively decreased, a large number of rotating portions 11 have to be provided, which makes the structure complicated.
In this way, the joint 9 has the following structure: the bending angle of the joint 9 can be finely adjusted according to the number of the rotating portions 11 provided in the joint 9 and the size of the rotating angle of each rotating portion 11.
Fig. 10 is a perspective view showing a state where the suction head 12 is detached from the joint 9. A slide groove 37 is formed at the tip of the fixing portion 10 of the joint portion 9, and a cutout groove 39 into which a projection 38a of an engagement member 38 described later is fitted is formed in a part of the slide groove 37.
On the other hand, a hole 40 is formed in a side surface of a portion of the suction head 12 toward the rear (toward the connecting tube portion 8 side), and the engaging member 38 is configured to be inserted into the hole 40 in the side surface. The engaging member 38 has a projection 38a, and the projection 38a can be fitted into the notch groove 39 provided in the slide groove 37. With this structure, the engaging member 38 can be slid on the slide groove 37.
If the suction head 12 is simply fitted over the tip of the joint 9, the suction head 12 is easily detached from the joint 9. Therefore, in the present embodiment, the following configuration is made: the two engaging members 38 can be inserted into the holes 40 of the suction head 12, and the engaging members 38 can be slid on the slide grooves 37 of the joint 9.
Therefore, the suction head 12 can be rotated in the direction of the arrow C-C' in fig. 10 (clockwise or counterclockwise about the direction in which the joint 9 extends) in a state of being fitted over the joint 9, and the suction head 12 can be prevented from being easily detached from the joint 9.
The two engaging members 38 slide on the slide grooves 37, and can be restricted from rotating when the convex portions 38a of the engaging members 38 are fitted in the notch grooves 39. The dust can be sucked in a state where the convex portion 38a of the engaging member 38 is fitted in the notched groove 39, that is, in a state where the suction head 12 is fixed to the joint 9 at a predetermined angle with respect to the joint 9.
In this state, when the user rotates the suction head 12 in the direction of arrow C-C' shown in fig. 10, the convex portion 38a of the engaging member 38 moves from the notch groove 39 to the slide groove 37 and slides on the slide groove 37, and the suction head 12 can be rotated with respect to the joint 9.
Since the joint portion 9 and the engaging member 38 are both formed of, for example, resin, the convex portion 38a of the engaging member 38 can be moved from the notch groove 39 to the slide groove 37 by the elastic force of the resin.
In this way, in the present embodiment, as shown in fig. 8 and 9, the suction piece 7 can be bent into a substantially L-shaped state by bending the joint portion 9. As shown in fig. 2 and 10, the suction head 12 can be rotated in the arrow C-C' direction with respect to the joint 9, that is, in the clockwise direction or the counterclockwise direction with respect to the direction in which the joint 9 extends.
As shown in fig. 2 and 10, the suction head 12 can be bent to a degree that the direction in which the joint 9 extends forms a substantially L-shape by rotating the suction head 12 in the direction of the arrow B-B' about the axis a as a rotation axis.
In this manner, in the present embodiment, dust at a high place, for example, on the top of a cabinet or the like can be sucked by bending the joint 9. Further, since the suction head 12 can be rotated to a degree that the direction in which the joint 9 extends forms a substantially L-shape, dust can be easily sucked even in a narrow space.
Further, since the light emitting unit 13 is mounted on the tip end of the suction head 12 of the present embodiment, dust can be sucked by irradiating light even in a narrow and dark place.
As described above, the suction material 7 of the present embodiment includes: a connecting tube portion 8 which is capable of expansion and contraction; a joint part 9 having a plurality of rotating parts 11, the joint part 9 being connected to the connecting tube part 8; and a suction head 12 rotatably connected to the joint 9 with respect to the joint 9, wherein each of the plurality of rotating portions 11 has a convex portion 35 and a bottom groove portion 34. The joint 9 is configured as follows: the plurality of rotating portions 11 are connected to each other by a shaft portion, and the convex portions 35 provided in the plurality of rotating portions 11 are inserted into the bottom groove portions 34 of the rotating portions 11 to be connected among the plurality of rotating portions 11.
In this way, since the convex portion 35 and the bottom groove portion 34 are provided in the rotating portion 11, even if the rotating angle is set to be large and the gap portion formed by the bent portion between the adjacent rotating portions 11 is expanded largely, the gap portion can be partially closed by the convex portion 35.
As a result, the pivot angle of each of the plurality of pivot portions 11 of the joint portion 9 can be increased, and the joint portion 9 can be bent at a large pivot angle.
When the joint 9 is bent, the convex portions 35 provided in the plurality of rotating portions 11 partially block the gap portions formed in the bent portions between the adjacent rotating portions 11, thereby preventing the fingers of the user from being caught in the gap portions.
In the suction tool 7 of the present embodiment, it is preferable that the convex portion 35 is inserted into the deepest portion of the bottom groove portion 34 of the rotating portion to be connected in a state where the adjacent rotating portions 11 of the plurality of rotating portions 11 are connected to each other and in a non-rotating state where the adjacent rotating portions 11 are horizontally positioned on substantially the same straight line. On the other hand, by rotating at least one rotating unit 11 of the plurality of rotating units 11 constituting the joint unit 9, the joint unit 9 is configured to: the joint 9 is bent between adjacent ones of the plurality of rotating portions 11, and in this state, a part of the convex portion 35 protrudes outward from the bottom groove portion 34.
With this configuration, when the turning portions 11 are positioned substantially on the same straight line, the convex portion 35 does not protrude outward, and therefore, when the turning portions 11 are held by the user, the convex portion 35 does not come into contact with the hand of the user, and the user does not feel uncomfortable. On the other hand, when the angle is provided between the rotating portions 11, that is, when the joint portion 9 is bent between the rotating portions 11, the convex portion 35 is exposed to the outside and partially blocks the gap between the rotating portions 11, and therefore, the fingers of the user can be prevented from being caught by the gap between the rotating portions 11.
In addition, according to the present embodiment, the suction tool 7 having the above-described features is communicated with the cleaner body 1, and the electric blower for generating suction air is built in the cleaner body 1, so that it is possible to provide the electric vacuum cleaner 100 in which the suction head 12 can be extended to a deep position such as a deep position on the upper surface of a high cabinet where a hand is not sufficient.
Further, according to the present embodiment, the vacuum cleaner 100 having the suction tool 7 in which the rotation angle of each of the plurality of rotation portions 11 of the joint portion 9 can be increased and the joint portion 9 can be bent at a large rotation angle that cannot be achieved in the structure without the convex portion 35 and the bottom groove portion 34 can be obtained.
Further, it is possible to provide the electric vacuum cleaner 100: when the joint portion 9 is bent, the convex portions 35 provided to the plurality of turning portions 11 partially block the gap portions generated in the bending portion between the adjacent turning portions 11 among the plurality of turning portions 11 constituting the joint portion 9, thereby preventing the user's fingers from being caught in the bending portion between the turning portions 11 when the joint portion 9 is bent.
As described above, the present invention has the following special effects: the joint 9 can be bent at a large rotation angle, so that dust can be collected even in a narrow place or dust in a deep place on a high cabinet where a hand cannot reach, and the fingers of a user can be prevented from being caught by the bent portion of the bent joint. Therefore, the present invention can be widely applied to a suction member for sucking dust, and a household electric vacuum cleaner, a commercial electric vacuum cleaner, and the like using the suction member.
