  Since the extension tube 5 is detachable from the hand operation unit 4, it is possible to remove the extension tube 5 from the hand operation unit 4 and suck dust from an opening (not shown) of the hand operation unit 4. It is also possible to remove the nozzle 6 from the extension pipe 5 and suck dust from an opening (not shown) of the extension pipe 5.

  FIG. 2 shows an external perspective view of the suction tool 7 in the present embodiment. The suction tool 7 can be attached to the hand operation unit 4 instead of the extension tube 5, and can also be attached to the extension tube 5 instead of the nozzle 6.

  In FIG. 2, the suction tool 7 in the present embodiment includes a connection pipe portion 8 serving as a coupling portion coupled to the hose 2 or the extension tube 5, a joint portion 9, and a suction head serving as a suction body for sucking dust. 12. The connecting pipe part 8 can be expanded and contracted in the extending direction of the suction tool 7, and the user can extend and contract the connecting pipe part 8 while pressing the operation button 20. On the other hand, when the user does not press down the operation button 20, the connecting pipe part 8 cannot be expanded and contracted, and the length of the connecting pipe part 8 is maintained. In the present embodiment, the width of the suction head 12 is substantially the same as that of the connecting pipe portion 8.

  The joint portion 9 includes a plurality of rotating portions 11 described later, and can be bent stepwise. The structure and bending operation 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, the suction head 12 extends in a direction perpendicular to the axis A (in the state of FIG. 2, the direction in which the connecting pipe portion 8 extends). Can be rotated in the direction of arrow BB ′, ie, in the direction perpendicular to the direction in which the suction tool 7 extends. It is.

  Further, the suction head 12 can rotate in the direction of the arrow C-C ′ in FIG. That is, the suction head 12 can rotate clockwise or counterclockwise around the direction in which the connecting pipe portion 8 extends in the state of FIG.

  A light emitting portion 13 is formed at the tip of the suction head 12, and the light emitting portion 13 has an outer shell formed of a transparent resin or the like for emitting light to the outside. A semiconductor light emitting device such as (Light Emitting Diode) 119 (described in FIG. 14) is arranged, and light from the LED 119 can be emitted to the outside.

  In addition, a switch operation unit 14 for causing the LED 119 to emit light or extinguish is formed on the top of the suction head 12, and the user can cause the LED 119 to emit light or extinguish by sliding the switch operation unit 14. Is possible.

  FIG. 3 is an exploded perspective view of the connecting pipe portion 8, and FIG. 4 is an enlarged sectional view of the vicinity of the operation button 20 of the connecting pipe portion 8.

  3 and 4, a cover 16 is fitted into one end of the outer extension pipe 15, and an inner extension pipe 18 is inserted into the other end via a stopper 17. A first opening 19 is formed in the lower part of the outer extension pipe 15.

  A first protrusion 21 that protrudes inward is formed integrally with the operation button 20 inside the operation button 20, and a spring 22 is inserted into the first protrusion 21. Further, a first locking portion 23 is attached to one end of the operation button 20, and the first locking portion 23 is accommodated in a first opening 19 provided at the lower portion of the outer extension tube 15. Has been placed.

  The first locking portion 23 is locked in any one of the plurality of first groove portions 24 formed in the inner extension tube 18, so that the inner extension tube 18 slides with respect to the outer extension tube 15. Be regulated.

  In addition, a second protrusion 26 of the locking plate 25 is disposed at a position facing the first protrusion 21 of the operation button 20. The above-described spring 22 is also inserted into the second protrusion 26, and the spring 22 is interposed between the first protrusion 21 and the second protrusion 26.

  Normally, the operation button 20 is urged downward in FIG. 4 by the elastic force of the spring 22, and the first locking portion 23 is urged upward in FIG. For this reason, the 1st latching | locking part 23 is latched by the 1st groove part 24, and the sliding of the inner side extension pipe | tube 18 with respect to the outer side extension pipe | tube 15 is controlled.

  When the user depresses the operation button 20 against the urging force of the spring 22, the operation button 20 is depressed in the upward direction in FIG. 4, and accordingly, the first locking portion 23 is moved in FIG. It moves downward and the locking of the first locking portion 23 to the first groove portion 24 is released. In this way, the inner extension tube 18 is slidable with respect to the outer extension tube 15.

FIG. 5 is an exploded perspective view of the joint 9. The joint portion 9 includes a plurality of rotating portions 11 and one fixing portion 10, and includes three rotating portions 11 and one fixing portion 10 in the present embodiment. Each rotating portion 11 has a substantially circular third protrusion 27 at one end, and a substantially circular first hole 28 and a notch 30 at the other end.

  The third projecting portion 27 of the rotating portion 11 is inserted into the first hole 28 of the adjacent rotating portion 11, and the rotating portion 11 has the insertion portion as an axis B and the front is in the direction D in FIG. It can be rotated about 30 degrees in a direction perpendicular to the direction in which the rotating portion 11 extends.

  In addition, this about 30 degrees means that it is possible to rotate up to about 30 degrees between two adjacent rotating parts 11. For example, as in the present embodiment, the rotating part 11 When there are three, the rotation can be rotated up to about 90 degrees in the cumulative total of the rotation from the first rotation unit to the third rotation unit. That is, the rotation part 11 on the first connecting pipe part 8 side with respect to the fixing part 10 can rotate up to about 90 degrees.

  An inclined surface 29 is formed in front of the rotating portion 11 (on the suction head 12 side), specifically, in the vicinity of the upper portion of the third protrusion 27 so as to be inclined downward from the rear toward the front. A notch 30 in which a notch part is widened from the rear to the front of the rotating part 11 is located behind the rotating part 11 (on the connecting pipe part 8 side), specifically in the vicinity of the upper part of the first hole 28. Is formed.

  FIG. 6 is an enlarged perspective view of a connecting portion between the rotating portions 11. Two grooves of an upper groove 31 and a lower groove 32 are formed inside both side surfaces behind the rotating part 11, while notches 33 are formed outside both side surfaces in front of the rotating part 11.

  Both the upper groove 31 and the lower groove 32 have a substantially triangular shape whose width becomes narrower from the rear to the front of the rotating portion 11, and is parallel to the direction in which the rotating portion 11 extends. There is one side of this triangle. Further, the upper groove 31 and the lower groove 32 have a symmetrical shape as if they were mirrored with the extending direction of the rotating portion 11 as an axis (tube axis direction).

  On the other hand, the notch 33 has a substantially triangular shape that gradually becomes wider from the front to the rear.

  By fitting the notch 33 into the upper groove 31 or the lower groove 32, it is possible to prevent a large to medium wobble that may hinder the cleaning operation between the rotating parts 11 that are engaged with each other. doing. However, some play may be formed between the lower groove 32 or the upper groove 31 and the notch 33, and it is possible to cause slight wobble by this play.

  In the state where the notch 33 is present in the upper groove 31, the rotation angle between the two rotating portions 11 that are fitted to each other is approximately 0 degrees, and the tube axes of the rotating portions are in the same direction. It is in an extended state.

  Next, when the rotating part 11 is rotated by a predetermined angle or more in a state where the notch 33 is present in the upper groove 31, the rotating part 11 is formed of resin, so that the elastic force causes The existing notch 33 gets over the boundary between the upper groove 31 and the lower groove 32 and moves to the lower groove 32. By such an operation, as described with reference to FIG. 5, the rotating portions 11 can rotate to about 30 degrees, and this angle can be maintained when the rotating parts rotate about 30 degrees.

  Note that this angle is not limited to about 30 degrees, and depending on the shape of the notch 33 and the upper groove 31 or the lower groove 32, an angle of 30 degrees or more or an angle of less than 30 degrees can be used.

  This time, the number of grooves is set to two, that is, the upper groove 31 and the lower groove 32. However, the number of grooves is not limited to this number, and may be set to three or more. However, if the number of grooves is increased, a finer angle can be set, but the rotating part 11 becomes larger or the holding force of the joint becomes weaker, so the total value of the upper groove 31 and the lower groove 32 is Two to eight are suitable.

  FIG. 7 is a perspective view of the state in which the suction head 12 is mounted on the joint portion 9 as viewed from below. In FIG. 7, three bottom groove portions 34 are formed on the lower rear side of the rotating portion 11, while three projecting portions 35 are formed on the lower front side of the rotating portion 11. The three projecting portions 35 are arranged so as to be inserted into the three bottom groove portions 34, respectively. A brush 36 is formed under the suction head 12, and a suction port 41 is formed so as to be surrounded by the brush 36. The dust wiped off by the brush 36 is sucked from the suction port 41 and sent to the dust collecting chamber of the cleaner body 1.

  FIG. 8 is a perspective view showing a state where the joint portion 9 is bent. It is possible to bend the joint part 9 in this way by rotating the rotating parts 11. As described above, since it is possible to rotate between the two rotating parts 11 up to about 30 degrees, in the configuration of FIG. 8 in which the three rotating parts 11 exist, the joint part 9 as a whole is about 90 degrees. It is possible to rotate up to.

  Next, the rotation parts 11 are fitted and connected as described above, and the rotation angle between the rotation parts 11 is approximately 0 degrees, that is, no rotation, that is, as shown in FIG. In a state where the two rotating portions 11 are positioned substantially in a straight line, the projecting portion 35 is inserted deepest into the bottom groove portion 34 and is buried in the rotating portion 11 of the other party or is in the same plane.

  As described above, when the rotating portions 11 are straight and substantially aligned, the protruding portion 35 is not exposed to the outside, so that the protruding portion 35 does not hit the hand when the user holds the rotating portion 11 portion. No discomfort to the user.

  At this time, there is no problem even if the protruding portion 35 protrudes to such an extent that the finger does not feel uncomfortable. Subsequently, in this state, when the rotating portion 11 is rotated and the joint portion 9 is bent, as shown in FIG. 8, a part of the projecting portion 35 of the one rotating portion 11 is replaced with the other rotating portion 11. It is exposed to the outside from the bottom groove portion 34.

  The projecting portion 35 exposed to the outside partially closes the gap 42 generated at the valley portion between the rotating portions 11 due to the rotation, and acts so that a human finger does not enter.

  Therefore, by adopting such a configuration, not only can the rotation angle of the rotation unit 11 be increased, but also when the rotation unit 11 rotates, the user's finger moves the rotation unit 11. It is made not to be pinched by the part of the gap 42 generated between them.

  As shown in FIG. 9, when only the first rotating part 11 is bent, it bends about 30 degrees, and when the second rotating part 11 is also bent, it bends to about 60 degrees. When 11 is bent, the joint 9 is bent to about 90 degrees. In such a state where the bending angle is increased, the suction head 12 of the suction tool 7 can be swallowed to the back of the top surface of the chest and the top surface of the air conditioner indoor unit, and cleaning has been difficult until now. It is also possible to clean out of reach.

In addition, the number of the rotation parts 11 can be increased any number. Increasing the number of rotating parts 11 makes it possible to further increase the turning angle and change the shape into an arbitrary shape, but increase the number of rotating parts 11. Since the joint portion 9 is too large and heavy, and the length of the joint portion 9 is long, the number of the rotating portions 11 is preferably 2 to 8, and the bending angle by one rotating portion 11 is also 5 degrees. -40 degrees is preferable. If the bending angle is increased too much, delicate angle adjustment cannot be performed, and if it is too small, many rotating parts 11 must be bent, which is complicated.

  FIG. 10 is a perspective view showing a state in which the suction head 12 is removed from the joint portion 9. A sliding groove 37 is formed at the distal end of the fixed portion 10 of the joint portion 9, and a notch groove 39 for fitting a convex portion 38 a of a notch member 38 to be described later into a part of the sliding groove 37. Is formed.

  On the other hand, holes 40 are formed on both side surfaces behind the suction head 12, and a notch member 38 can be inserted into the holes 40 on both side surfaces. Further, the notch member 38 is slidable on the sliding groove 37, and the convex portion 38a of the notch member 38 is fitted into the notch groove 39.

  If the tip of the joint portion 9 is simply inserted into the suction head 12, the suction head 12 easily falls out of the joint portion 9. For this reason, in the present embodiment, the two notch members 38 are slid on the sliding groove 37 of the joint portion 9 with the two notch members 38 inserted through the holes 40 of the suction head 12.

  For this reason, the suction head 12 can be rotated in the direction of the arrow CC ′ in FIG. 10 (clockwise or counterclockwise around the extending direction of the joint 9 as an axis) while being inserted into the joint 9. In addition, the suction head 12 is not easily removed from the joint portion 9.

  Further, the two notch members 38 slide on the sliding grooves 37, and the rotation can be restricted when the convex portions 38a of the respective notch members 38 are fitted into the notch grooves 39. Dust can be sucked in a state in which the convex portion 38 a of the notch member 38 is fitted in the notch groove 39, that is, in a state where the suction head 12 is fixed to the joint portion 9 at a predetermined angle.

  In this state, the user rotates the suction head 12 in the direction of the arrow CC ′ shown in FIG. 10 so that the convex portion 38a of the notch member 38 rides from the notch groove 39 to the sliding groove 37 and slides. Thus, the suction head 12 can be rotated with respect to the joint portion 9.

  Since the joint portion 9 and the notch member 38 are both formed of resin, for example, the convex portion 38a of the notch member 38 can run from the notch groove 39 to the sliding groove 37 by its elastic force. .

  Thus, in this Embodiment, it is possible to bend the suction tool 7 to a substantially L-shaped state by bending the joint part 9 as shown in FIG. 8, FIG. Further, as shown in FIGS. 2 and 10, the suction head 12 is moved in the direction of the arrow CC ′ with respect to the joint portion 9, that is, clockwise or counterclockwise about the extending direction of the joint portion 9 as an axis. It is possible to rotate.

  Further, as shown in FIGS. 2 and 10, the suction head 12 is moved in the direction of the arrow BB ′ with respect to the joint portion 9, that is, in the direction perpendicular to the extending direction of the joint portion 9. The suction head 12 can also be rotated, and the suction head 12 itself can be bent so as to be substantially L-shaped.

As described above, in the present embodiment, it is possible to suck up dust at a high place, for example, on the chiffon, by bending the joint 9, and the suction head 12 is L-shaped with respect to the joint 9. By turning it into a shape. Dust can be easily sucked even in a narrow space.

  In addition, since the light emitting unit 13 is mounted on the tip of the suction head 12 according to the present embodiment, it is possible to illuminate the light even in a narrow and dark place.

  Next, the configuration of the suction head 12 will be described in detail with reference to FIGS.
