Abstract

The invention discloses a multidirectional oscillating type fan which comprises a base (6), a bracket (4), a fan head (2), a driving motor (7), an oscillating system (3), and fan blades (1). A protruding rotating shaft (41) at the lower part of the bracket (4) and a concave shaft hole (61) on the base (6) constitute a revolute pair; the fan head (2) is hinged on the bracket (4) by the protruding rotating shaft (41); the fan head (2) is also provided with a driven gear (34) which rotates under the driving of the driving motor (7); and one end of a connecting sheet (5) is hinged on the end face of a gear (34) and the other end thereof is connected onto the base (6). As the length of the connecting sheet (5) is fixed, when the driven gear (34) rotates, the fan can generate vertical oscillation. Moreover, the bracket (4) also generates horizontal oscillation which takes the rotating shaft (41) as a shaft center. The fan has the function that three degrees of freedom can work simultaneously, and causes the wind area of the fan to be enlarged.

Description

technical field [0001] The present invention relates to a fluid conveying device, in particular to an electric fan for air conveying. Background technique [0002] In the prior art, the swing of the fan head has two degrees of freedom, and the other degree of freedom is adjusted by screws. The fan only has the function of swinging back and forth like this, but does not have the function of working simultaneously with three degrees of freedom, and the wind receiving area is small. Contents of the invention [0003] The object of the present invention is to provide a multi-directional oscillating fan with three degrees of freedom and a large wind-receiving area in order to avoid the above-mentioned shortcomings of the prior art. [0004] The present invention is realized by implementing the following technical solutions: a multi-directional oscillating fan, including a base, a fan head, fan blades and a driving motor; the fan head is movably connected to the base, and a Wi...
