As shown in fig. 1-6, the present embodiment provides an automatic and manual swing structure of a fan.
The fan head is mounted on the swing head bracket 100 and can rotate along with the swing head bracket 100;
the swing bracket 100 is provided with an automatic swing mechanism and a manual swing mechanism, and the automatic swing mechanism drives the swing bracket 100 to rotate through a synchronous motor 200; the manual swing mechanism applies force to the fan head through external force, so that the fan head rotates relative to the mounting frame 300.
The above is the basic scheme of the present embodiment. In a conventional fan, a fan head is mounted on a swing bracket 100, and the swing bracket 100 drives the fan head to perform pitching and swinging. Meanwhile, the swing bracket 100 is rotatably connected to the mounting frame 300, and the mounting frame 300 and the support base are fixed.
When the fan performs pitching and head swinging, the head swinging bracket 100 rotates relative to the mounting frame 300. When a user electrifies the fan to automatically swing, the synchronous motor 200 rotates to drive the swing bracket 100 to rotate, so that the pitching and swinging of the head of the fan are realized;
when the fan head is manually pitching and swinging, the fan head drives the swing bracket 100 to rotate relative to the mounting frame 300.
Preferably, in this embodiment, the angle at which the fan head automatically swings is 30 ° and the angle at which the fan head manually swings at pitch is 90 °.
Through setting up two kinds of modes of automatic swaying and manual swaying to the fan head, can make the fan head realize the swaying of wide-angle, satisfy user's angle of blowing needs, simultaneously, the angle of automatic swaying still limits in synchronous motor 200's bearing range, avoids synchronous motor 200 overload to lead to's motor damage.
Specifically, the manual swing mechanism includes a damping block 800 rotatably connected to the swing bracket 100, where the damping block 800 and the support base are fixed; when the fan head swings by an external force, the swing head bracket 100 rotates relative to the damping block 800.
When a user manually swings the fan head to adjust the blowing direction, the swing head bracket 100 rotates and generates a great friction force with the damping block 800, and when the external force is removed, the fan head can be stopped at any angle.
In this embodiment, a limiting assembly is further disposed on the damping block 800, the limiting assembly includes a limiting plate 400 and a limiting sleeve 500, and the limiting sleeve 500 is fixed with the damping block 800;
the limiting plate 400 is provided with a limiting protrusion 410, and the limiting sleeve 500 is provided with a limiting baffle 510 extending towards the limiting protrusion 410.
The limiting structures on the limiting plate 400 and the limiting sleeve 500 can also be regarded as that an arc-shaped notch is arranged on the limiting plate 400, the limiting protrusion 410 rotates in the notch, and two end parts of the notch are two limit positions of the swing of the fan head.
In this embodiment, two limiting protrusions 410 are disposed on the limiting plate 400, and a region between the two limiting protrusions 410 is a rotation range of the limiting baffle 510, and a position where interference occurs between the limiting baffle 510 and the two limiting protrusions 410 is two limit positions of the swing of the fan head.

And the stop collar 500 is fixed to the mounting frame 300, so that the stop collar 500 does not rotate, and the stop plate 400 rotates relative to the stop collar 500. When the fan head swings to the limit position, the limit protrusion 410 and the limit baffle 510 on the limit plate 400 interfere, and the limit plate 400 cannot continue to rotate.
When the limiting plate 400 rotates, the damping plate is fixed, and damping force can be generated between the end face of the limiting plate 400 and the damping plate, so that in order to ensure the fixation of the damping plate, a positioning protrusion 520 is arranged on the end face of the limiting sleeve 500, which is in contact with the damping block 800, and a positioning groove 401 capable of accommodating the positioning protrusion 520 is arranged on the outer wall of the damping block 800.
