Description
本發明係關於一種扇輪，特別是關於一種能夠防止水或油等液體附著在扇輪表面，同時亦可避免灰塵堆積之扇輪。The present invention relates to a fan wheel, and more particularly to a fan wheel capable of preventing liquid such as water or oil from adhering to the surface of the fan wheel while also avoiding dust accumulation.
由於電子產品在使用時係會發出高熱，因此必須藉由散熱裝置(例如：散熱風扇)加以驅熱，藉此降低電子產品的工作溫度，以便該電子產品能夠維持於一較佳工作效能。Since the electronic product emits high heat during use, it must be heated by a heat sink (for example, a heat dissipating fan), thereby lowering the operating temperature of the electronic product so that the electronic product can be maintained at a better working efficiency.
請參照第1圖所示，習知散熱風扇之扇輪9係包含一輪轂91及數個葉片92，該輪轂91設有一轉動軸911，用以作為旋轉支點；該數個葉片92係等間距排列設置於該輪轂91之外周壁。該習知扇輪9係可透過該轉動軸911裝設於一扇框之軸座，並可藉由一定子驅動該習知扇輪9旋轉作動，以便該習知扇輪9可導入外界氣流，並驅動外界氣流進行散熱作用。Referring to FIG. 1 , the conventional fan of the cooling fan 9 includes a hub 91 and a plurality of blades 92. The hub 91 is provided with a rotating shaft 911 as a pivot point; the plurality of blades 92 are equally spaced. Arranged on the outer peripheral wall of the hub 91.

And drive the external airflow for heat dissipation.
一般而言，在長時間使用下，由於該習知扇輪9之輪轂91及葉片92的表面係容易附著有水或油等液體，導致灰塵容易沾附於該輪轂91及葉片92表面，造成雜質及污垢的堆積，如此，該灰塵及污垢除了會降低該習知扇輪9的進、出風量，而嚴重影響該習知散熱風扇之散熱效率外，甚至造成該習知扇輪9於實際旋轉過程中容易發生左右晃動的現象，導致該習知扇輪9之相關構件互相碰撞而損壞，進而相對縮短習知結構的使用壽命。又，隨著電子產品微型化的趨勢，使得灰塵相對於微型化散熱風扇之進、出風量的影響更為顯著，如此，導致散熱風扇之散熱效率更容易由於灰塵及污垢的堆積而明顯呈現下滑的趨勢，造成無法有效降低電子零件的運作溫度，進而相對縮短電子產品的使用壽命。基於上述原因，其確實有必要進一步改良上述習知扇輪9。In general, in the long-term use, since the surface of the hub 91 and the blade 92 of the conventional fan wheel 9 is likely to adhere to a liquid such as water or oil, dust is likely to adhere to the surface of the hub 91 and the blade 92, resulting in The accumulation of impurities and dirt, in addition to the fact that the dust and dirt can reduce the amount of air entering and exiting the conventional fan wheel 9, and seriously affect the heat dissipation efficiency of the conventional cooling fan, and even cause the conventional fan wheel 9 to actually The phenomenon of swaying is prone to occur during the rotation process, causing the related components of the conventional fan wheel 9 to collide with each other and damage, thereby shortening the service life of the conventional structure. Moreover, with the trend of miniaturization of electronic products, the influence of dust on the inflow and outflow of the miniaturized cooling fan is more significant. As a result, the heat dissipation efficiency of the cooling fan is more likely to fall due to the accumulation of dust and dirt. The trend is that the operating temperature of electronic components cannot be effectively reduced, thereby shortening the service life of electronic products. For the above reasons, it is indeed necessary to further improve the above-described conventional fan wheel 9.

請參照第4圖所示，其揭示本發明第二實施例之扇輪，相較於第一實施例，第二實施例之扇輪另設有一轉動軸4，且該輪轂1之軸心位置設有一軸座13，該轉動軸4之一端對應結合於該軸座13，並容置於該輪轂1之容置空間12內。在本實施例中，該轉動軸4之表面同樣設有該撥液層3，且該撥液層3較佳僅選擇形成於該轉動軸4鄰近該軸座13之表面；或者，該撥液層3亦可選擇完全包覆於該轉動軸4之表面。Referring to FIG. 4, a fan wheel according to a second embodiment of the present invention is disclosed. Compared with the first embodiment, the fan wheel of the second embodiment is further provided with a rotating shaft 4, and the axial position of the hub 1 is A shaft seat 13 is disposed. One end of the rotating shaft 4 is coupled to the shaft seat 13 and is received in the receiving space 12 of the hub 1 . In this embodiment, the surface of the rotating shaft 4 is also provided with the liquid-repellent layer 3, and the liquid-repellent layer 3 is preferably only formed on the surface of the rotating shaft 4 adjacent to the shaft seat 13; Layer 3 may also optionally be completely coated on the surface of the rotating shaft 4.
請參照第5及6圖所示，本發明第二實施例於實際使用時，在該扇輪透過該轉動軸4及一軸承81可轉動的結合於該風扇裝置8之一軸管82內的情形下，該轉動軸4上之撥液層3在軸向上係略高於該軸承81之頂面；當該轉動軸4旋轉作動時，該轉動軸4及軸承81之間的潤滑油係會受到離心力的導引而沿著該轉動軸4之外壁面上升；當該潤滑油上升至與該轉動軸4表面之撥液層3互相接觸時，由於該潤滑油無法附著於該撥液層3，如此，該潤滑油則無法再沿著該轉動軸4之外壁面上升，同時藉由該轉動軸4旋轉時所產生的慣性力，使該潤滑油得以順勢脫離該轉動軸4之撥液層3，並藉此沿著該軸承81之表面回流至該軸承81內，使該轉動軸4及軸承81之間保有較佳之含油量，有效避免該潤滑油外洩而影響該風扇裝置8之壽命。Referring to FIGS. 5 and 6, in the actual use, the second embodiment of the present invention is rotatably coupled to a shaft tube 82 of the fan unit 8 through the rotating shaft 4 and a bearing 81. The liquid-repellent layer 3 on the rotating shaft 4 is slightly higher than the top surface of the bearing 81 in the axial direction; when the rotating shaft 4 is rotated, the lubricating oil between the rotating shaft 4 and the bearing 81 is subjected to The centrifugal force is guided to rise along the outer wall surface of the rotating shaft 4; when the lubricating oil rises to contact the liquid-repellent layer 3 on the surface of the rotating shaft 4, since the lubricating oil cannot adhere to the liquid-repellent layer 3, In this way, the lubricating oil can no longer rise along the outer wall surface of the rotating shaft 4, and the lubricating oil can be released from the liquid-repellent layer 3 of the rotating shaft 4 by the inertial force generated when the rotating shaft 4 rotates. Therefore, the surface of the bearing 81 is returned to the bearing 81 to maintain a better oil content between the rotating shaft 4 and the bearing 81, thereby effectively preventing the lubricating oil from leaking and affecting the life of the fan device 8.
藉此，本發明第二實施例之扇輪，除了與該第一實施例所述具有相同之作用及功效外，該第二實施例更可使該轉動軸4及軸承81之間保有較佳之含油量，維持該轉動軸4及軸承81之間的自潤能力，並進一步提升電子產品的使用年限。Therefore, in addition to the same functions and functions as those of the first embodiment, the second embodiment of the present invention can better maintain the rotation between the rotating shaft 4 and the bearing 81. The oil content maintains the self-lubricating ability between the rotating shaft 4 and the bearing 81, and further improves the service life of the electronic product.
雖然本發明已利用上述較佳實施例揭示，然其並非用以限定本發明，任何熟習此技藝者在不脫離本發明之精神和範圍之內，相對上述實施例進行各種更動與修改仍屬本發明所保護之技術範疇，因此本發明之保護範圍當視後附之申請專利範圍所界定者為準。While the invention has been described in connection with the preferred embodiments described above, it is not intended to limit the scope of the invention.
