[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0018] Please refer to Figs. 1 to 4 The utility model provides a technical scheme.

[0019] A novel fan oscillation mechanism includes a fan head frame 1 and a fan base 9. A fan motor 8 is coaxially connected to the fan head frame 1. A mounting plate 6 is mounted on the surface of the fan motor 8. An oscillation motor 7 is mounted on the surface of the mounting plate 6. The oscillation motor 7 serves as a power output to realize the oscillation of the fan head frame 1 and the fan motor 8 mounted on the fan head frame 1. A transmission block 5 is fixedly connected to the output end of the oscillation motor 7. A transmission plate 4 is rotatably connected to the surface of the transmission block 5. Connecting ear plates 2 are fixedly connected to both sides of the fan head frame 1. Each end of the fan base 9 is rotatably connected to a connecting ear plate 2. A fixed shaft seat 3 is fixedly connected to both ends of the fan base 9. One of the fixed shaft seats 3 is rotatably connected to one end of the transmission plate 4.

[0020] By starting the oscillating motor 7, the transmission block 5 is driven to rotate, and the rotation of the transmission block 5 will in turn drive the transmission plate 4 to move. At this time, the transmission plate 4 will swing around the connection point with the fixed shaft seat 3. Since the fixed shaft seat 3 is connected to the fan seat 9, the fixed shaft seat 3 will remain in a fixed position. According to the principle of action and reaction, when the transmission plate 4 swings as described above, a reaction force will be generated. This reaction force will cause the oscillating motor 7, the mounting plate 6, the fan motor 8, and the fan head frame 1 to move up and down in an "oscillating" motion. This setting can achieve the coordinated movement of multiple components without complex linkage mechanisms, which helps to simplify the overall structure and reduce production and maintenance costs.

[0021] A torsion spring 10 is installed inside the fixed shaft seat 3. The surface of the fan head frame 1 is provided with an insertion groove 11 for one end of the torsion spring 10 to be inserted. The other end of the torsion spring 10 is inserted into the inner wall of the fixed shaft seat 3. The elastic force of the torsion spring 10 can provide a stable elastic constraint for the up and down oscillation of the fan head, making the movement of the fan head more stable, reducing the overall instability of the fan caused by the oscillation during the oscillation process, and improving the safety and reliability of the fan during use.

[0022] The fan motor 8 and the fan head frame 1, the mounting plate 6 and the fan motor 8, the oscillating motor 7 and the mounting plate 6, and the fixed shaft seat 3 and the fan seat 9 can be connected by bolts, which can achieve both fixation and easy disassembly.

[0023] The transmission plate 4 has an arc-shaped structure.

[0024] The fan head bracket 1 has a circular structure.

[0025] Specifically, the solution is as follows: When the oscillating motor 7 is started, the transmission block 5 fixedly connected to its output end begins to rotate under the drive of the oscillating motor 7. The transmission plate 4 rotatably connected to the surface of the transmission block 5 moves with the rotation of the transmission block 5. The transmission plate 4 swings with its connection point with the fixed shaft seat 3 as the center. The fixed shaft seat 3 is connected to the fan seat 9 and keeps its position unchanged. According to the principle of action and reaction, the reaction force generated by the swing of the transmission plate 4 causes the oscillating motor 7, the mounting plate 6, the fan motor 8 and the fan head frame 1 to present an up-and-down "oscillating" motion state, thereby controlling the change of the air delivery angle of the fan head installed on the fan motor 8. When the fan head frame 1 oscillates up and down, it will cause the connecting ear plate 2 and the fan seat 9 to produce relative swinging motion.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
