[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0021] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0022] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0023] Reference Figures 1-5An oscillating fan designed to prevent wire tangling includes a housing consisting of a base 1 and an outer shell 2. A fan motor 4, driven by an oscillating motor 3, is installed inside the housing. The stator of the fan motor 4 is fixedly fitted with a wire-passing component 5 for threading wires. The outer shell 2 has several circumferentially arranged limiting grooves 6. The wire-passing component 5 has an insertion part 7 corresponding to each limiting groove 6, and the insertion part 7 is inserted into the limiting groove 6.

[0024] After the wire passes through the wire guide 5, it is electrically connected to the stator of the fan motor 4. When the fan motor 4 is driven to rotate and oscillate by the oscillating motor 3, the stator does not rotate. At the same time, the wire guide 5 is restricted from rotating due to the cooperation between the insertion part 7 and the limiting groove 6. The wire passes through the wire guide 5 and is electrically connected to the stator of the fan motor 4. When neither the stator nor the wire guide 5 rotates, the problem of wire tangling will not occur.

[0025] The outer side of the wire threading member 5 is provided with an extension portion 13 consisting of a transverse portion and a longitudinal portion. The two ends of the transverse portion are respectively connected to the wire threading member 5 and the longitudinal portion. The outer side of the longitudinal portion is provided with a wire mounting portion 14. The side of the transverse portion near the longitudinal portion is provided with a first wire threading hole 15. The base 1 is provided with a second wire threading hole 16 for threading the wire into the housing. The external wires are threaded into the housing through the second wire threading hole 16, and after being positioned by the wire mounting portion 14, they are threaded through the first wire threading hole 15 to the position of the stator of the fan motor 4 and electrically connected to the stator of the fan motor 4.

[0026] The rotating shaft of the oscillating motor 3 is equipped with an eccentric connector 8. The end of the eccentric connector 8 is rotatably connected to the upper end of the rotating shaft of the fan motor 4. The fan motor 4 is an external rotor motor in which the external rotor rotates and the internal stator is fixed. The rotor is fixedly connected to the rotating shaft of the fan motor 4. The rotating shaft of the fan motor 4 is rotatably connected to the wire threading member 5. The eccentric connector 8 is connected to the rotating shaft of the fan motor 4 through a first bearing 9. A second bearing 10 is provided between the rotating shaft of the fan motor 4 and the wire threading member 5.

[0027] When both the oscillating motor 3 and the fan motor 4 are started, the rotational smoothness between the shaft of the fan motor 4 and the eccentric connector 8 is greatly improved due to the first bearing 9, and the rotational smoothness between the shaft of the fan motor 4 and the wire threading member 5 is greatly improved due to the second bearing 10.

[0028] The outer shell 2 has a concave cavity 11 at its center. The limiting grooves 6 are arranged circumferentially within the concave cavity 11. The size of the limiting grooves 6 is larger than the size of the insert part 7. When the fan motor 4 is driven to swing by the oscillating motor 3, the limiting grooves 6 have sufficient space for the insert part 7 to move. That is, when the fan motor 4 swings to one side, the gap between the limiting groove 6 and the insert part 7 on that side is the smallest, while on the opposite side, the gap between the limiting groove 6 and the insert part 7 is the largest. When the fan motor 4 swings, the gap on the side with the smallest gap begins to gradually increase, while the gap on the side with the largest gap begins to gradually decrease. No matter where the fan motor 4 swings, at least one set of the limiting grooves 6 and the insert part 7 will play a limiting role. The movement between the limiting grooves 6 and the insert part 7 is similar to the meshing effect of gears.

[0029] The lower end of the wire threading component 5 is equipped with a universal rotating component 12, which is installed in the center of the concave cavity 11, further improving the smoothness of the rotation and oscillation of the fan motor 4.

[0030] Furthermore, a wave-shaped gasket is installed between the wire threading component 5 and the universal rotating component 12. After the product is installed, the wave-shaped gasket is squeezed to generate elasticity, which pushes the universal rotating component 12 to always fit the center of the concave cavity 11, thus avoiding jamming.
