Because intake pipe 9 and outlet duct 10 can take place to buckle, the embodiment of the utility model provides an, adopt and make first opening be less than the second opening to make the shape of second opening be the shape that first opening was swept when rotatory, the second opening is the curved surface opening promptly, thereby the air current that flows out from first opening always flows in outlet duct 10 through the second opening.

The embodiment of the utility model provides an in, at the articulated department of intake pipe 9 and outlet duct 10, the outside of intake pipe 9 is at least for using articulated axis as the partly of the solid of revolution of central line, because the outside of intake pipe 9 is the solid of revolution for the outside of intake pipe 9 always can contact with second open-ended edge, thereby guarantees that intake pipe 9 and outlet duct 10's articulated department can not outwards leak out.

Because the shape and the size of second opening are great, in order under the prerequisite that does not influence suction force, suitably reduce revolution mechanic's volume, the embodiment of the utility model provides an, first open-ended size slightly is less than or equal to intake pipe 9's air inlet size to obviously reduce second open-ended size, cross sectional dimension minimum department is first opening part in the whole airflow channel, consequently slightly reduces first opening and the second opening that obviously reduces, and the influence to dust catcher suction force can be ignored.

The embodiment of the utility model provides an in, the air inlet size of intake pipe 9 is greater than first open-ended size, and whole intake pipe 9 is even reducing pipe to the sectional area that makes the air current that gets into in the intake pipe 9 changes more evenly level and smooth, avoids impacting because of the air current that the air current sectional area suddenly changes and arouses, leads to suction power to reply the loss.

When the suction pipe is in a bent state, the trend of the airflow passage changes, and once the airflow passage is bent too obviously, airflow is unsmooth, so that the suction force of the dust collector is greatly reduced, and the cleaning efficiency of the dust collector is lowered. In the embodiment of the utility model, the second opening is provided with a spoon-shaped channel which takes the hinge axis as the central line; the spoon-shaped channel is communicated with the air outlet of the air outlet pipe 10. Because spoon shape passageway is the great crooked passageway of camber, and the obvious bending of true passageway only exists in first opening and second open-ended contact department, the air current way of buckling many that has relatively, the embodiment of the utility model provides a can weaken the loss that the air current route of buckling produced to suction force, consequently guaranteed higher suction force, the dust catcher also possesses higher clean efficiency.

To sum up, the utility model discloses the inner structure of implementing can possess still less buckling, more level and smooth air current route, bigger suction under the prerequisite that realizes air current route and buckle.

As shown in fig. 1, in the embodiment of the present invention, the two ends of the rotating structure along the hinge axis are both provided with the main cover plate 3 for protecting the hinge; the center of the main cover plate 3 is provided with a transparent cover plate 4, which is convenient for a user to observe the inside condition of the rotating structure.

In addition, the main cover plate 3 and the transparent cover plate 4 form a spherical cap-shaped structure, that is, the whole rotating structure is spherical, so that the rotating structure is more attractive.

In the same reason, the processing degree of difficulty and processing cost are considered, the embodiment of the utility model provides an in, first shell 6 and second shell 7 only set up in revolution mechanic department, intake pipe 9 and outlet duct 10 only set up in revolution mechanic and go out, first body and second body break away from revolution mechanic's regional back, only set up the one deck body, and first body and intake pipe 9 structure as an organic whole, second body and intake pipe 9 structure as an organic whole, except more pleasing to the eye, can also reduce the processing degree of difficulty and the processing materials that inhale the pipe, thereby reduce the utility model discloses the processing cost of embodiment.

In order to facilitate the connection between the suction pipe and other devices, in the embodiment of the utility model, one end of the first pipe body, which is far away from the rotating structure, is provided with a first connecting part 1 for connecting parts such as a brush head of a dust collector; one end of the second pipe body, which is far away from the rotating structure, is provided with a second connecting part 2 for connecting with a suction inlet of a main machine of the dust collector.

Illustratively, the first connecting part 1 and the second connecting part 2 are connected in a plugging mode, and are locked through a buckling and unlocking structure, so that the connection part is prevented from being disconnected.

It should be noted that the first connecting portion 1 and the second connecting portion 2 can adopt different connecting modes and locking modes, such as threaded connection and locking. Consider that the part of current dust catcher all adopts the universalization design, the embodiment of the utility model provides an in, first connecting portion 1 and second connecting portion 2 can set up to general connection structure as actual need.
