It is connected. The first rotating shaft 11 is arranged along the vertical direction, and the bottom end is connected to the second driving device, and when the second driving device rotates the first rotating shaft 11, the first rotating shaft 11 rotates 360°. can do. The first post 2 includes a turntable 21, an inverted U-shaped frame 22, and a second base portion 23. The turntable 21 is provided on the first base portion 1, and the top end of the first rotating shaft 11 is fitted. , both are relatively fixed. Both bottom ends of the inverted U-shaped frame 22 are fitted and fixed to the turntable 21, and the center line of the inverted U-shaped frame 22 and the first rotation shaft 11 are aligned in the horizontal projection direction of the side surface of the oscillating fan. The angle is 0 to 180°, and the angle can be set according to actual needs during the actual use. The second base portion 23 is fitted into the U-shaped notch of the inverted U-shaped frame 22 and connected to the inner wall of the U-shaped notch of the inverted U-shaped frame 22 with bolts. When the first rotating shaft 11 rotates, the turntable 21 is rotated to rotate the inverted U-shaped frame 22 and the second base part 23 , that is, the first rotating shaft 11 rotates the entire structure of the first column 2 . Rotate and the rotation angle is also 360°. A second rotating shaft 24 and a third driving device for rotating the second rotating shaft 24 are provided in the second base portion 23. In the horizontal projection direction of the side surface of the oscillating fan, the second rotating shaft 24 and an inverted U-shape are provided. Preferably, the second axis of rotation 24 is perpendicular to the centerline of the inverted U-shaped frame 22 instead of overlapping or parallel to the centerline of the mold frame 22 . One end of the second rotating shaft 21 is located in the second base portion 2 and fixed to the third driving device, and the other end is hinged to the oscillating fan body 3, specifically speaking, oscillating.

Of course, a third drive can also be provided in the same way. Since the turntable 21 is fitted into the first base portion 1, the turntable 21 does not protrude from the base portion, thereby improving the appearance of the oscillating fan.

The above oscillating fan can be used as a fan with blades. That is, as shown in FIG. and a first drive 34 for rotating the fan blades 33, the first drive 34 also being electrically connected to the circuit board. Of course, the above oscillating fan can be used for a bladeless fan, and the structure of the bladeless fan is a general structure in this field, so the description thereof is omitted here.

In a further refinement, the first base part 1 is provided with a human-computer interaction device connected to the control board, said human-computer interaction device may be a button, there may be more than one button, one of which is the first Controlling one drive controls the rotation of the fan blades, and the remaining buttons control the rotation of the second to fourth drives to adjust the blowing direction. When the button is pressed, it sends a first electrical signal to the control board to control the rotation of the corresponding drive. Of course, you can also control the oscillating fan via a remote control. Specifically, the oscillating fan is provided with a remote control and an infrared receiver, the infrared receiver is electrically connected to the control board, and the remote control controls the turning on and blowing angle of the oscillating fan. In order to accommodate the remote controller, the first base part is provided with a groove for accommodating the remote controller, so that the remote controller can be put into the groove when the remote controller is not needed.

Apparently, the above-described embodiments of the present invention are given by way of illustration for the purpose of describing the present invention rather than limiting the embodiments of the present invention. A person of ordinary skill in the art can make many different changes or variations based on the above description. It is not necessary or possible to cover all embodiments here.
