4. The universal oscillating fan as claimed in claim 1, wherein the middle position of the cross bar is fixedly connected with the top end of the rotating shaft, and a fan head assembly is fixedly installed at both ends of the cross bar.
5. The universal oscillating fan of claim 1, wherein an angle sensor is mounted between the shaft and the vertical bar assembly.
6. The universal oscillating fan of claim 1, wherein the cross bar is internally provided with a power source and a control module for controlling the independent driving of the fan head assembly.
7. A universal oscillating fan according to claim 3 or 4, wherein the fan head assembly comprises blades, a shield for surrounding the blades and a drive motor for driving the blades to rotate, both of which are mounted on the motor mount and fixedly mounted on the cross bar/connecting rod via the motor mount.
8. A method of controlling a universal oscillating fan as claimed in any one of claims 1 to 6, characterized by the following:
when the transverse shaking head is needed for blowing air, the rotating speed difference between the fan head assemblies at the two ends of the cross rod is alternately controlled, so that the rotating speed of the fan head assembly at one end of the cross rod is higher than that at the other end of the cross rod, and the cross rod is alternately and circularly controlled;
when vertical shaking is needed for blowing, the first vertical rod and the second vertical rod are adjusted to be in a vertical state, and the rotation speed difference between the fan head assemblies at the two ends of the cross rod is alternately and circularly controlled, so that the rotation speed of the fan head assembly at one end of the cross rod is higher than that at the other end of the cross rod;
or, the first vertical rod and the second vertical rod are coaxially and vertically arranged, and the rotation speed difference between the two groups of fan head components at the upper layer and the lower layer is alternately and circularly controlled, so that the rotation speed of the fan blades of the fan head components at the same layer is the same and higher than that of the fan blades at the other layer.
9. The method for controlling a universal oscillating fan according to claim 8, wherein when the air supply is required to be oscillated obliquely, the first vertical rod and the second vertical rod are adjusted to be in a state of a set included angle, and the rotation speed difference between the fan head assemblies at the two ends of the cross rod is controlled in an alternating and circulating manner;
or, the first vertical rod and the second vertical rod are coaxially and vertically arranged, and the rotation speed difference of the two fan head assemblies at the diagonal positions is alternately and circularly controlled, so that the rotation speed difference of the two fan head assemblies at one diagonal position is the same as the rotation speed of the two fan head assemblies at the other diagonal position.
10. The method of claim 8, wherein when space-wise oscillating air supply is required, controlling the rotational speed of the fan head assembly at one corner to be cyclically changed within a set time while the rotational speeds of the fan head assemblies at the other corners are unchanged, and sequentially controlling the rotational speeds of the other fan head assemblies in a clockwise or counterclockwise direction.
