Description

[Technical field]

[0001] The present application relates to the technical field of oscillating fans, and in particular to anti-tangle wire oscillating fans. [Background technology]

[0002] The electric fan of the prior art can usually only achieve a certain range of oscillation, and cannot achieve 360-degree oscillation in all directions. Obviously, an electric fan that can oscillate in all directions of 360 degrees can make the air flow smoother and improve the ventilation effect. To achieve 360-degree oscillation in all directions, it is necessary to consider how to prevent the wire from getting tangled, which is a technical problem of the prior art.

[0003] Therefore, designing an oscillating fan with anti-tangle wire function is a pressing problem in the prior art. Summary of the Invention [Problem to be solved by the invention]

[0004] The present application aims to design an oscillating fan with wire tangling prevention, which can achieve any rotation between the head assembly and the base without the occurrence of the phenomenon of wire tangling by providing a wire passing rotation shaft. In addition, the oscillating fan of the present application can change direction at the same time as swinging, and this structure effectively improves the drawback of the limited blowing angle of the circulator. [Means for solving the problem]

[0005] The present application relates to a wire tangle-preventing oscillating fan comprising a base and a head assembly, a first synchronous motor provided on the base, the head assembly rotating relative to the base by the first synchronous motor, a drive gear connected to an output shaft of the first synchronous motor, a driven gear connected to the drive gear, a bearing provided within the driven gear, and a wire-passing rotation shaft provided at the center of the bearing.

[0006] The driven gear may be inclined at an angle of 20 to 40 degrees, and the driving device may further include a base and a second synchronous motor, the base rotates relative to the base by the second synchronous motor, a synchronous motor fixing plate may be fixedly connected to the base, the second synchronous motor may be fixed to the synchronous motor fixing plate, an axial bush may be provided between the base and the base, the base may rotate relative to the base by the axial bush, an output shaft of the second synchronous motor is connected to an eccentric member, the eccentric member is connected to the axial bush via a link, a support ring may be further provided between the base and the base, a circular hole may be provided in the support ring, a ball may be provided in the circular hole, a head frame may be connected to the driven gear, and the head assembly is connected to the head frame. Effect of the Invention

[0007] The present application provides a bearing with a rotating shaft through which wires pass, allowing any rotation between the head assembly and the base to be achieved without the occurrence of the phenomenon of wire tangling. By designing two synchronous motors to rotate and drive the base and the head assembly, respectively, the fan can also change various angles while swinging, forming a more three-dimensional blowing effect and improving the user experience. The present application provides more practicality to users through the left and right swing mechanism, and not only can the blowing direction be adjusted at multiple angles, but also various needs can be met by individually controlling the combination of the two swing synchronous motors.
