Further, the pivot-connecting position of the outlet side wall body of two of described nozzle assembly inlet ends and described pedestal is provided with seal ring.
Further, described gear ring can be fixed on the inlet end of described nozzle assembly, also can be one-body molded with the inlet end of described nozzle assembly; Described ball and spring fitting are in the preset holes of the outlet side of described pedestal wall body, and described ball one end is supported mutually with spring, and the other end is supported and coordinated with the tooth position on gear ring surface.
Further, the outlet side of described air-flow path is provided with a T shape guide duct, relative and the setting that keeps at a certain distance away of two inlet ends of the two ends of the horizontal pipe of this T shape guide duct and described nozzle assembly, the vertical tube of this T shape guide duct is connected with the outlet side of described air-flow path.
Further, the perisporium at the two ends of the horizontal pipe of described T shape guide duct is provided with the stop lug coordinating with described base internal wall backstop.
Further, two inlet ends of described nozzle assembly stretch into respectively the outlet side of described pedestal, and with the rotatable pivot joint of inwall of the outlet side of described pedestal.
Further, described nozzle assembly relatively pedestal within the scope of 0～360 degree, carry out pivotable.
The beneficial effects of the utility model are:
First, this is without in blade fan, and two inlet ends of nozzle assembly are articulated on the wall body of outlet side of pedestal rotationally, makes by this nozzle assembly can do around pedestal the pitching rotation of wide-angle, and then has met the wide-angle adjustment demand of jet-impingement direction.Meanwhile, operation is simple for the angular adjustment of nozzle assembly, only needs corresponding rotary nozzle assembly, and can rotate to any angular position and use, and greatly facilitates user.
Secondly, because nozzle assembly is direct and the rotatable pivot joint of pedestal, thereby omit the parts such as pivot, and reduced thus design cost, facilitated user's installation and removal.
Again, when idle without blade fan, can also, by nozzle assembly rotary folding to flat condition, take up room to save, facilitate depositing or transporting of fan.

Embodiment:
The embodiment who provides below in conjunction with accompanying drawing is described further the utility model.
As shown in Figures 1 to 5, the utility model is novel provides a kind of pivotable without blade fan, comprises pedestal 1 and the nozzle assembly 2 by this pedestal 1 support, is provided with air-flow path 3 and in order to produce impeller 4 and the motor 5 of air-flow in pedestal 1.The inlet end of air-flow path 3 is opened on the outer surface of pedestal 1, and described opening is and is arranged on some air inlets 31 that pedestal 1 outside is rule or irregular alignment, and the outlet side of air-flow path 3 is connected with the inlet end 21 of nozzle assembly 2.
Also comprise two groups of positioning devices 6 that formed by gear ring 61, ball 62 and spring 63, these two groups of positioning devices 6 are separately positioned on the pivot-connecting position of two inlet ends 21 with the outlet side wall body of pedestal 1 of nozzle assembly 2, in order to the pivoted position of nozzle assembly 2 is positioned.So, user can rotate nozzle assembly 2 to any angular position and use, and the present embodiment is preferably within the scope of 0～360 degree.In addition, two inlet ends 21 of nozzle assembly 2 are provided with seal ring 7 with the pivot-connecting position of the outlet side wall body of pedestal 1, in order to prevent that air-flow from overflowing from the pivot points of the two.
