The specific embodiment
Below, with reference to accompanying drawing 6 to 8, an embodiment of vacuum cleaner nozzle of the present invention is elaborated.
As shown in Figure 6, suction nozzle 130 suction lines 300 of the present invention comprise combination 310 and body 320.In the combination 310 of suction line 300, upside position (below be referred to as " upper end ") 311 structure is compared with hemisphere, more approaches spheroid form.
That is, as shown in Figure 7, the downside position of combination 310 (below, be referred to as " lower end ") 312 is formed near the bending point C, and its upper end 311 surpasses bending point C.
The combination 310 of suction line 300 is combined on the rotation section 120 in the mode that can rotate up and down.
In the present embodiment, the structure of the structure of main part 110 and rotation section 120 is identical, but need not make it necessarily have as above structure.
The upper end 311 of combination 310 has the shape that approaches sphere structure.When suction line 300 was rotated, combination 310 front side distal portion---opening 313 can not be exposed on the external by cap 122 cutting openings 123 of rotation section 120, can prevent the slit in advance.
Certainly,, might bring the difficulty of pattern manufacturing operation, but this can be resolved by changing the shape of combination 310 lower ends 312 internal faces because the curved surface of combination 310 surpasses bending point C.
That is, make lower end 312 internal faces of combination 310 have the inclined plane structure, rather than original curved-surface structure, allow it from the closure of 310 of body 320 and combinations, downward-sloping certain angle just can carry out pattern 500 separating operations at an easy rate.
Here have certain angle of inclination, as long as this angle is for being used in the pattern 500 that forms combination 310 curved surfaces, from the closure of 310 of body 320 and combinations, the getting final product of downward-sloping disengaging angle.
Such as, body 320 is about 30 ° with the angle of combination 310 openings 313, then the angle between the direction of the disengaging direction of pattern 500 and opening 313 also is 30 °, and also should be 30 ° with respect to the internal face angle of inclination of combination 310 lower ends 312.
Thereby, can break away from pattern 500 easily, and then can allow the upper end 311 of combination 310 reach the position that is higher than bending point C.
313 formation directions to direction and pipeline 320 of the opening of combination 310 rapid bending should not occur, and be gradual be bent into suitable.
In a word, can be by changing the shape of suction line 300 combinations 310, as shown in Figure 8, the cap 122 that forms suction nozzle highly is reduced to minimum constructive height, and when suction line 300 turned to minimum position, the height of body 320 can not be higher than cap 122, thereby can reduce the whole height H 2 of suction nozzle.
Moreover, in the suction line 300 of the present invention, the connecting portion that combination 310 and body are 320 has curved surface slowly.
Therefore, the crooked position 43c between traditional suction line 43 combination 43a and the body 43b can not occur, can avoid the phenomenon of the air constricted flow brought because of crooked position 43c.
In addition, after combination 310 shapes of change suction line 300, the thickness of combination 310 lower ends 312 is quite thick.
That is, lower end 312 outside wall surface of combination 310 closely are connected with the internal face of rotation section 120 path guide parts 121, prevent leakage of air with this.When therefore the internal face of combination 310 lower ends 312 had the inclined plane structure, the closer to the connecting portion of combination 310 and body 320, the thickness of combination 310 lower ends 312 can be thick more.
When the thickness of the lower end 312 of combination 310 was very thick, the shrinkage phenomenon that operations for forming is thick was obvious more.
In order to address the above problem, the present invention has and the identical thickness in combination 310 upper ends the lower end 312 of combination 310, and in the outside wall surface of combination 310 lower ends 312, an above rib 314 is set, interval between closed lower 312 and the path guide part 121 prevents leakage of air.
Each rib 314 is pressed the outstanding formation of certain altitude, and the top is positioned on the same sphere of combination 310 upper ends 311.Each rib 314 respectively between across certain intervals.
In a word, in the embodiments of the invention, by rib 314 is set, prevent the bad generation behind the operations for forming in advance, and eliminate the slit between combination 310 and the rotation section 120, can prevent leakage of air to greatest extent.
