Fig. 5 is the exploded perspective view of joint portion 9.Joint portion 9 has multiple rotation section 11 and a fixed part 10.In the present embodiment, joint portion 9 comprises 3 rotation sections 11 and a fixed part 10.A pair the 3rd teats 27 of circular are provided with in the side of the part of (by dust collecter 12 side) on the front of rotation section 11, a pair the 1st hole portions 28 of circular are provided with in the side of the part of (by connecting section 8 side) rearward of rotation section 11, and, be provided with breach 30 in the part of (by connecting section 8 side) rearward of rotation section 11.
3rd teat 27 of rotation section 11 can be inserted into the 1st hole portion 28 of adjacent rotation section 11.By the 3rd teat 27 is inserted into the 1st hole portion 28, thus rotation section 11 can as shown in Figure 5, with axis B for arbor makes the part of (by dust collecter 12 side) on the front of rotation section 11 rotate about 30 degree to the D direction (direction vertical with the direction that the joint portion 9 with multiple rotation section 11 extends) in Fig. 5.
In addition, these about 30 degree of such angles refer to can rotate about 30 degree between two adjacent rotation sections 11, such as when as present embodiment, be linked with 3 rotation section 11, add up to from the accumulation of the rotational angle till rotation section 11,11 to the 3, first rotation section and can rotate about 90 degree.That is, the multiple rotation sections 11 linked up can rotate about 90 degree relative to fixed part 10.When being linked with 5 rotation section 11, multiple rotation sections 11 entirety linked up can rotate about 150 degree relative to fixed part 10.
And, under the state that rotational angle between rotation section 11 is about 0 degree, as aftermentioned, all rotation sections 11 are not all rotated, but as shown in Figure 7, adjacent rotation section 11 is roughly located along the same line each other, joint portion 9 roughly point-blank extends.
Rotation section 11 (by dust collecter 12 side) on the front, above the 3rd teat 27 near be formed with autorotation portion 11 rear (by connecting section 8 side) toward the front (by dust collecter 12 side) go and downward-sloping inclined plane 29.On the other hand, rotation section 11 (by connecting section 8 side) rearward, above the 1st hole portion 28 near be formed with autorotation portion 11 rear go toward the front and the breach 30 of breach expansion.
Fig. 6 is the stereogram obtained after amplifying the coupling part of multiple rotation sections 11 that will link up.Upper slot 31 and these two grooves of lower channel 32 are formed in the inner side of the side of the part of (by connecting section 8 side) rearward of rotation section 11.On the other hand, projection (Japanese: ノ ッ チ) 33 is formed with in the outside of the side of the part of (by dust collecter 12 side) on the front of rotation section 11.
The rear that upper slot 31 and lower channel 32 are autorotation portion 11 is gone and the shape of the general triangular that the width of groove narrows gradually toward the front, and a limit in the general triangular that upper slot 31 is respective with lower channel 32 is formed as parallel with the direction that the joint portion 9 with multiple rotation section 11 extends.And, upper slot 31 and lower channel 32 with the limit of in general triangular for axle (tube axis direction), in as if upper slot 31 and lower channel 32 are by the such symmetric shape of Mirror Symmetry, wherein, a limit in this general triangular refers to a limit parallel with the direction that the joint portion 9 with multiple rotation section 11 extends.
On the other hand, protruding 33 fronts that are autorotation portion 11 are gone towards rear and the shape of general triangular that width broadens gradually.
By making protruding 33 to embed upper slot 31 or lower channel 32, thus can prevent generation between the rotation section 11 of tabling from can hinder rocking of the such degree of cleaning work.But, also can form a little gap in lower channel 32 or between upper slot 31 and protruding 33, utilize this gap to allow the weak vibrations producing and can not hinder the such degree of cleaning work.
And under protruding 33 states embedding upper slot 31, the rotational angle between mutually chimeric rotation section 11 is roughly 0 degree, become the state that the respective tubular axis line in mutual chimeric rotation section 11 extends in the same direction.
At this, can to protruding 33 all can rotate with mutually different rotational angle and the structure of this different rotational angle can be kept to be described in the structure in embedded groove portion 31,32 and multiple rotation section 11 selectively.
Under protruding 33 states embedding upper slot 31, when rotation section 11 is rotated more than predetermined angular, because rotation section 11 is formed by resin, therefore, the projection 33 of embedding upper slot 31 crosses the boundary between upper slot 31 and lower channel 32 under the effect of the elastic force of the resin of rotation section 11, moves and is embedded into lower channel 32.Under protruding 33 states embedding lower channel 32, when rotation section 11 is rotated more than predetermined angular, protruding 33 can cross the boundary between lower channel 32 and upper slot 31, move and are embedded into upper slot 31.By such action, protruding 33 can embed plural groove portion 31,32 selectively, and can keep the rotational angle after rotating.
In addition, rotational angle is not limited to about 30 degree, also can according to protruding 33 and groove portion shape and be set as the angle of more than 30 degree or be less than the angle of 30 degree.
And, the respective rotational angle in multiple rotation section 11 is not necessarily identical angle (being such as about 30 degree), and multiple rotation section 11 all can be rotated with mutually different rotational angle according to protruding 33 and the shape in groove portion 31,32 and the number in groove portion.
And in the present embodiment, groove portion is provided with upper slot 31 and these two grooves of lower channel 32, but also can be not limited to two and be set as more than 3.But, when increasing the number in groove portion, although can set angle more subtly, rotation section 11 also can be made but then to become greatly, weaken the confining force in joint, therefore, it is desirable that upper slot 31 and lower channel 32 add up to 2 ~ 8.
Fig. 7 observes the stereogram that the state that is provided with dust collecter 12 at joint portion 9 obtains from below.
As shown in Figure 7,3 kerve portions of place 34 are formed with at the position of (by connecting section 8 side) rearward downside of rotation section 11.On the other hand, 3 place's convex shaped parts 35 are formed with at the position of (by dust collecter 12 side) on the front downside of rotation section 11.Convex shaped part 35 and kerve portion 34 is configured with in the mode that these 3 convex shaped parts 35 can be inserted into 3 kerve portions 34 respectively.
Fig. 8 is the stereogram of the state after representing joint portion 9 bending.Make multiple rotation sections 11 of formation joint portion 9 rotate respectively, thus joint portion 9 can be made to bend.As mentioned above, each rotation section 11 can be made to rotate about 30 degree, therefore, in the structure of Fig. 8 being linked with 3 rotation sections 11, joint portion 9 unitary rotation about 90 degree can be made.
Like this, because the multiple rotation sections 11 being located at joint portion 9 are configured to the structure that can rotate separately, therefore, joint portion 9 be configured to can by the multistage bend.And joint portion 9 becomes such structure: according to the size of the number of rotation section 11 and the rotational angle of each rotation section 11 of being located at joint portion 9, trickle adjustment can be carried out to the bending angle of joint portion 9.
Be formed with hairbrush 36 in the bottom of dust collecter 12, and suction inlet 41 is formed in the bottom of dust collecter 12 in the mode of being surrounded by hairbrush 36.Can be inhaled into from suction inlet 41 by the dust that hairbrush 36 is wiped, and be fed in the dust storage chamber of main body of dust collector 1.
And multiple rotation section 11 couples together in mode chimeric each other as described above.Rotational angle between adjacent rotation section 11 be about 0 degree, under state that multiple rotation section is not all rotated, namely under the state that two as shown in Figure 7, adjacent rotation sections 11 are positioned on roughly same straight line, convex shaped part 35 is inserted into the bosom in kerve portion 34, becomes a rotation section 11 and imbeds as the state in another rotation section 11 of its chimeric object or the state that is positioned at another rotation section 11 as its chimeric object on same.
When being configured to two adjacent rotation sections 11 like this and being positioned at as the crow flies each other on roughly same straight line, convex shaped part 35 can not be given prominence to laterally, therefore, when user holds rotation section 11 part, convex shaped part 35 can not encounter the hand of user, thus can not bring uncomfortable sensation to making user.
In addition, convex shaped part 35 now also can be made the degree of indisposed sense being brought to give prominence to laterally to the finger of user.
Then, when making rotation section 11 rotate and joint portion 9 is bent in this condition, as shown in Figure 8, a part for the convex shaped part 35 of a rotation section 11 in two adjacent rotation sections 11 is given prominence to laterally from the kerve portion 34 of another rotation section 11.
And the part outstanding laterally of this convex shaped part 35 by gap 42 local stoppages of the paddy shape kink generation along with rotation between rotation section 11, thus can prevent the finger of people from entering gap 42.
Thus, adopt such structure, can not only increase the rotational angle of rotation section 11, can also prevent when rotation section 11 is rotated, the finger of user is clamped by gap 42 part produced between rotation section 11.
Fig. 9 is the side view of the state after the joint portion 9 of suction pieces 7 bends about 90 degree.
As shown in Figure 9, when only making first rotation section 11 bend, joint portion 9 bends about 30 degree, and when continuing to make second rotation section 11 bend, joint portion 9 is bent to about 60 degree, and when continuing to make the 3rd rotation section 11 bend, joint portion 9 bends about 90 degree.And, even if under the state of angle of bend increasing joint portion 9 in this wise, also can as described above, become not easily between the rotation section 11 of joint portion 9 generation can hinder the structure of rocking of the such degree of cleaning work.Thus, even if under the state of angle of bend increasing joint portion 9, the dust collecter 12 of suction pieces 7 also can be made to reach the depths of cupboard end face and indoor apparatus of air conditioner end face etc., can be difficult to so far be swept into, position that hand reaches cleans.
In addition, the number of rotation section 11 is not limited to 3, also can arrange more rotation section 11.By increasing the number of rotation section 11, can increase the angle that joint portion 9 can bend further, the shape that joint portion 9 also can be made to be changing into expectation uses.On the other hand, owing to adding the number of rotation section 11, also there is joint portion 9 and become excessive and become heavy or become long shortcoming.Therefore, it is desirable that the number of rotation section 11 is 2 ~ 8, and preferably, the angle that rotation section 11 can bend is 5 degree ~ 40 degree.When excessively increasing angle of bend, cannot trickle angular adjustment be carried out, when excessively reducing angle of bend, just having to arrange many rotation sections 11 thus structure can be made to become loaded down with trivial details.
Like this, joint portion 9 becomes such structure: can carry out trickle adjustment according to the size of the number of rotation section 11 and the rotational angle of each rotation section 11 of being located at joint portion 9 to the bending angle of joint portion 9.
Figure 10 represents the stereogram of dust collecter 12 from the state after joint portion 9 is pulled down.Sliding tray 37 is formed with, at the gap slot (Japanese: ノ ッ チ Ditch) 39 being partially formed the protuberance 38a embedding for fastened component described later (Japanese: ノ ッ チ portion material) 38 of sliding tray 37 on the top of the fixed part 10 of joint portion 9.

If be only the top merely dust collecter 12 being enclosed within joint portion 9, so dust collecter 12 easily comes off from joint portion 9.Therefore, in the present embodiment, such structure has been made: can, under the state in hole 40 that two fastened components 38 are inserted into dust collecter 12, fastened component 38 be slided on the sliding tray 37 of joint portion 9.
Therefore, dust collecter 12 is under the state being enclosed within joint portion 9, can rotate along the arrow C-C ' direction (direction extended with joint portion 9 be axis direction ground clockwise or counterclockwise) in Figure 10, and, can prevent dust collecter 12 from easily coming off from joint portion 9.
And two fastened components 38 slide on sliding tray 37, can limit rotation when the protuberance 38a of each fastened component 38 is embedded in gap slot 39.Under the state that can be embedded in gap slot 39 at the protuberance 38a of fastened component 38, namely dust collecter 12 is with suctioning dirt under the state being fixed on joint portion 9 relative to joint portion 9 mode in predetermined angular.
In such a state, dust collecter 12 rotates to the arrow C-C ' direction shown in Figure 10 by user, and thus, the protuberance 38a of fastened component 38 gets over to sliding tray 37 from gap slot 39, and slide on sliding tray 37, thus dust collecter 12 can be made to rotate relative to joint portion 9.
In addition, because joint portion 9 and fastened component 38 are all formed by such as resin, therefore, it is possible to utilize the elastic force of resin to make the protuberance 38a of fastened component 38 from gap slot 39 more to sliding tray 37.
