[0018] Figure 1A and Figure 1B Schematic diagram of a fan device of an embodiment of the present invention from different viewing angles. Figure 1A and Figure 1B The fan device 100 of this embodiment includes a shaft portion 110, a plurality of blades 120, and a protective structure 130. The blades 120 extend from the shaft portion 110. Figure 1A As shown, the protection structure 130 covers the blades 120 , and the protection structure 130 and the blades 120 rotate together with the shaft portion 110 at the same speed.

[0019] In this embodiment, the protective structure 130 is a mesh structure. The mesh structure includes a polygonal mesh, such as a honeycomb mesh, but the mesh structure is not limited thereto. Since the fan blades 120 are covered by the protective structure 130 and not directly exposed, the user's fingers can be prevented from being cut and injured by the rotating fan blades 120 by inserting them between the fan blades 120, and the fan blades 120 can be prevented from being damaged by impact, thereby affecting the integrity of the fan blades 120.

[0020] In addition, in this embodiment, since the protective structure 130 and the fan blades 120 rotate together with the rotating shaft portion 110, even if the user's fingers touch the protective structure 130, the protective structure 130 will be contacted in a surface contact manner, causing the protective structure 130 and the fan blades 120 to stop together, thereby greatly improving the safety of the fan blades 120 and the user and providing a special visual effect.

[0021] In this embodiment, the blades 120 are connected to the outer ring 140, and the protective structure 130 is fixed to the outer ring 140. In one embodiment, the protective structure 130 can be directly fixed to the blades 120. Of course, the fixing position and method of the protective structure 130 are not limited thereto.

[0022] In addition, in this embodiment, the blades 120 and the protective structure 130 are integrated. Of course, in other embodiments, the blades 120 and the protective structure 130 can also be made separately and fixed together, for example, by bonding, riveting, locking, etc. In other embodiments, the protective structure 130 can also be detachably provided on the blades 120, the shaft 110 and / or the outer ring, which is not limited to the drawings.

[0023] Figure 2A and Figure 2B is a schematic diagram of a fan device of another embodiment of the present invention from different viewing angles. Figure 2A and Figure 2B , Figure 2A The fan device 100a and Figure 1A The main difference of the fan device 100 is the shape and location of the protective structure 130a. Specifically, in this embodiment, the protective structure 130a includes a plurality of annular members 132, which are arranged gradually along the radial direction of the rotating shaft 110 with the rotating shaft 110 as the center, and the annular members 132 are connected to the fan blades 120.

[0024] The blades 120 are arranged in an inclined manner and respectively include a plurality of inclined surfaces 122. The annular members 132 are connected to a plurality of upper edges 124 of the blades 120. The protective structure 130a includes a plurality of extension members 134. Each of the extension members 134 extends from a corresponding annular member 132 to a corresponding inclined surface 122 to provide more support. In other words, in this embodiment, the protective structure 130a is directly fixed to the blades 120.

[0025] The adjacent two blades 120 of the fan device 100a of the present embodiment are connected by the annular member 132, which can reduce the probability of the user's fingers being inserted between the adjacent two blades 120 to avoid being cut and injured by the rotating blades 120, and can also prevent the blades 120 from being damaged by impact, thereby affecting the integrity of the blades 120. In addition, the protective structure 130a rotates with the rotating shaft portion 110 together with the blades 120. Even if the user's fingers touch the protective structure 130a, it is easier to touch the protective structure 130a in a surface contact manner (for example, contacting multiple annular members 132 and / or the arc-shaped area of ​​a single annular member 132 at the same time), so that the protective structure 130a and the blades 120 stop together, greatly improving the safety of the blades 120 and the user, and providing a special visual effect.

[0026] In addition, in this embodiment, the protective structure 130a is presented in the form of a ring-shaped member 132, which can have better angular momentum during rotation, so that the protective structure 130a can rotate smoothly. Of course, the form of the protective structure 130a is not limited thereto.

[0027] In summary, the protective structure of the fan device of the present invention at least partially covers or is disposed on the fan blades, thereby preventing the user's fingers from being easily inserted between the fan blades and being cut and injured by the rotating fan blades, and also preventing the fan blades from being damaged by impact, thereby affecting the integrity of the fan blades. In addition, the protective structure rotates with the fan blades along with the rotating shaft, so that even if the user's fingers touch the protective structure, it is easier to contact the protective structure in a surface contact manner, so that the protective structure and the fan blades stop together, greatly improving the safety of the fan blades and the user, and providing a special visual effect.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present case, rather than to limit it. Although the present case has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or part or all of the technical features can be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solution to deviate from the scope of the technical solution of the embodiments of the present case.
