Problems solved by technology
[0002] Because the air grille of the rotary blade fan can change the direction of the wind blown by the electric fan, people can feel more comfortable. However, the angle of the air grille of the current rotary blade fan is fixed, so, It is inconvenient to fix its wind direction and strength, so it brings certain restrictions to people's choices.

The invention relates to a rotary vane fan air grid with any change of wind direction, which is arranged on the large circle at the outer edge and the small circle at the middle part of an air grid frame respectively by rotating shafts at two ends of the air grid; a middle shaft is arranged on the small circle at the middle part of the air grid frame and is vertical to the plane of the small circle at the middle part of the air grid frame; teeth similar to bevel gears are manufactured on the circumference of the excircle of an adjusting knob; the adjusting knob is arranged on the middle shaft by the excircle of the middle thereof; simultaneously, the teeth on the adjusting knob and teeth on the air grid form a meshed relation; and a fixed knob is arranged on the middle shaft at the upper part of the adjusting knob.
Description
technical field [0001] The invention relates to a rotary vane fan grille, in particular to a rotary vane fan grille which can change the wind direction arbitrarily, and belongs to the technical field of household appliances. Background technique [0002] Because the air grille of the rotary blade fan can change the direction of the wind blown by the electric fan, people can feel more comfortable. However, the angle of the air grille of the current rotary blade fan is fixed, so, It is inconvenient to fix its wind direction, strength and weakness, so it brings certain restrictions to people's choice. Contents of the invention [0003] The purpose of the present invention is to provide a fan grille that can change the wind direction arbitrarily, the angle of the grille can be changed arbitrarily, so the wind direction and strength can be changed arbitrarily, so as to satisfy people's more choices on wind direction and strength . [0004] The technical solution adopted by th...
