[0001] This utility model relates to a fan, and more particularly to a fan with a stylus. Background Technology

[0002] With the rapid development of technology, the computing power of electronic components has increased significantly, but it also generates a lot of heat. To ensure that electronic components are not damaged by high heat, fans need to be installed on electronic products to dissipate excess heat and enable the electronic components to operate within a certain operating temperature range.

[0003] Generally, manufacturers focus more on fan performance. For example, the fan's heat dissipation capacity, lifespan, and operating noise are important considerations for manufacturers in their design.

[0004] However, manufacturers often neglect the entertainment aspect of fans when improving their performance, resulting in overly simplistic fan functionality. Therefore, how to make fans both effective at cooling and entertaining is one of the problems that researchers should address. Utility Model Content

[0005] The present invention provides a fan that can achieve both heat dissipation and entertainment.

[0006] An embodiment of this invention discloses a fan comprising a fan frame and a fan blade. The fan frame includes a bottom, a central tube, and a sound groove.

Figure 1 This is a perspective view of the fan according to an embodiment of the present invention. Figure 2 for Figure 1 The exploded diagram. Figure 3 for Figure 2 A partially exploded view. The fan 10 of this embodiment includes a fan frame 11 and a fan blade 12. The fan frame 11 includes a bottom 111, a central tube 112, a side part 113, a cover part 114, a sound groove part 115, and a stator 116.

[0024] The bottom 111 has a first surface 1111. The central tube 112 protrudes from the first surface 1111 of the bottom 111. The side 113 is connected to the bottom 111 and surrounds an accommodating space S1. The side 113 may also include a perforated structure 1131. The perforated structure 1131 communicates with the accommodating space S1. The cover 114 covers the side 113 and has an air inlet 1141. The air inlet 1141 communicates with the accommodating space S1, so that the airflow generated by the fan blade 12 enters the fan frame 11 from the air inlet 1141, passes through the accommodating space S1, and then exits outside the fan frame 11. The sound groove 115 is disposed on the first surface 1111 of the bottom 111. The sound groove 115 and the central tube 112 are located on the same side of the bottom 111. The fan blade 12 is located within the accommodating space S1. The stator 116 is composed of a plurality of silicon steel sheets wound with a plurality of coil sleeves, and the stator 116 is sleeved on the outside of the central tube section 112.

[0025] In this embodiment, the side portion 113 is designed with a hollow structure 1131, but this is not a limitation. In other embodiments, the side portion may not have a hollow structure.

[0026] The fan blade 12 includes a hub 121, a plurality of blade portions 122, an outer ring portion 123, a plurality of stylus portions 124, and a magnet 125. The blade portions 122 are connected to the periphery of the hub 121. The outer ring portion 123 is connected to the blade portions 122 and surrounds them internally. The stylus portions 124 are located on the side of the outer ring portion 123 near the bottom 111. The hub 121 is rotatably mounted on the central tube portion 112. The magnet 125 is connected to the hub 121. The magnet 125 is located on the inner edge of the hub 121 and can rotate relative to the stator 116 via electromagnetic effect, thereby driving the hub 121 to rotate relative to the fan frame 11.

[0027] The hub portion 121 extends from a central axis and is pivotally mounted on the central tube portion 112 along an axial direction C. Through the blade portions 122 and the outer ring portion 123, the stylus portions 124 are driven to movably contact the sound groove portion 115 along the axial direction of the central tube portion 112. In this way, the stylus portions 124 and the sound groove portion 115 together produce sound.

[0028] The outer ring portion 123 has a second surface 1231. The second surface 1231 faces the first surface 1111. The stylus portions 124 are disposed on the second surface 1231 of the outer ring portion 123.

[0029] The hub portion 121, the blade portions 122, the outer ring portion 123, and the stylus portions 124 are integrally formed. However, this is not a limitation; the hub portion 121, the blade portions 122, the outer ring portion 123, and the stylus portions 124 can also be joined by snap-fit.

[0030] There are four stylus parts 124, which are arranged at equal angles on the outer ring 123. However, this is not a limitation, and the number of stylus parts 124 can also be other numbers.

[0031] Please see Figures 4 to 5 . Figure 4 for Figure 1 A cross-sectional view of the fan when its speed is below the preset speed. Figure 5 for Figure 1 A cross-sectional view of the fan when it exceeds a preset speed. First, as... Figure 4 As shown, when the fan blade 12 rotates below a preset speed, the hub 121 slides along the axial direction C of the central tube 112, that is, along direction A, and approaches the bottom 111 so that the stylus parts 124 abut against the groove part 115. In this way, the stylus parts 124 and the groove part 115 together produce sound. Then, as... Figure 5 As shown, when the fan blade 12 rotates at a speed higher than a preset number of revolutions, the hub 121 will slide along the axial direction C of the central tube 112, that is, along the direction B, away from the bottom 111, so that the stylus parts 124 are separated from the sound groove part 115. The preset number of revolutions is, for example, 300 revolutions per minute, but it is not limited to this, and the preset number of revolutions can also be other values.

[0032] When the rotational speed of fan blade 12 is higher than the preset speed, fan blade 12 will generate a larger airflow. The airflow will overflow through air inlet 1141 in direction D.

[0033] According to the fan in the above embodiment, since the hub portion is movably disposed on the central tube portion along one axial direction, the stylus portion can be moved movably along the axial direction of the central tube portion to contact the sound groove portion. Therefore, when the stylus portion contacts the sound groove portion, the fan generates sound, thus achieving both heat dissipation and entertainment functionality.

[0034] More specifically, when the fan blades rotate at speeds below 300 revolutions per minute, the stylus will press against the sound groove, causing the stylus and sound groove to work together to produce sound, thus achieving both cooling and entertainment functions.

[0035] Although the present invention has been disclosed above with reference to the foregoing embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of patent protection of the present invention shall be determined by the scope of protection of the appended claims.
