The shortcoming of this blast device is: nozzle assembly is rotatably fixed on pedestal by the pivotal parts being made up of T-shaped hollow pipeline and flange on the one hand, when nozzle assembly rotates, must jointly be rotated as fulcrum using pivotal parts and pedestal, thereby complex structure, component are numerous, and design cost is high; On the other hand the rotation of nozzle assembly location be round and smooth dentation joint by flange periphery with ball and spring coordinate to realize, ball is connected in each recess of dentation joint, in actual use, particularly after length service time, easily there is " card bead " phenomenon, be that ball is stuck at the recess of dentation joint, and then cause the motionless or very difficult rotation of nozzle assembly rotation, thereby bring impact to the angular adjustment folding or airflow direction of blast device.
Model utility content:
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, provide a kind of simple in structure, cost is low, flexible operation is reliable, can easily realize the wide-angle adjustment of airflow direction, and can be when idle folding place can pivoted without blade fan.
The purpose of this utility model is achieved through the following technical solutions:
One is can pivotable collapsible without blade fan, comprise pedestal and the nozzle assembly by this pedestal support, in described pedestal, be provided with air-flow path and in order to produce impeller and the motor of air-flow, the inlet end of described air-flow path is opened on the outer surface of described pedestal, outlet side is connected with the inlet end of described nozzle assembly, described nozzle assembly has two inlet ends that are oppositely arranged, these two inlet ends are articulated in respectively the outlet side of described pedestal rotationally by O-ring seals, interference fit between the pivot joint face of the pivot joint face of described O-ring seals and described nozzle assembly inlet end and described pedestal outlet side, this interference fit makes described nozzle assembly when without External Force Acting, can keep motionless.
Further, two of described nozzle assembly inlet ends are articulated in respectively the outlet side of described pedestal rotationally by one or more O-ring seals.
Further, the pivot joint face of two of described nozzle assembly inlet ends is provided with the annular notch for accommodating described O-ring seals.
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, 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, described nozzle assembly relatively pedestal within the scope of 0～180 degree, carry out pivotable.
The beneficial effects of the utility model are:
First, cancelled pivotal parts, nozzle assembly is directly installed in rotation on pedestal, when nozzle assembly rotates, is rotated separately using pedestal as fulcrum, and therefore structure is more simple, and design cost is reduced, and assembles also convenient.
Secondly, adopt O-ring seals the rotation of nozzle assembly to be positioned and sealed, dual-use material, not only further simplify fan structure, but also can avoid card bead phenomenon, and guarantee reliability and flexibility that nozzle assembly rotates, so user-friendly.
Again, nozzle assembly can be done around pedestal the pitching rotation of wide-angle within the scope of 0～180 degree, and then has met the wide-angle adjustment demand of jet-impingement direction.
Finally, 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.
