Therefore, the service life of the fan blade can be greatly extended.

Description

具疏油/疏水之扇葉Fan blade with oleophobic/hydrophobic

本發明係有關於一種扇葉之設計，特別是指一種具疏油/疏水之扇葉。The present invention relates to the design of a fan blade, in particular to a fan blade with oleophobic/hydrophobic properties.

查，在扇葉的運用，不但可以加速空氣流動來進行循環流通的機制，當然對於馬達尺寸的不同設計，其所產生的驅動性能也會有所不同，且更鑒於在日常生活的空氣中夾雜許多微塵粒子，而這些微塵粒子會伴隨空氣中的水氣、亦或車輛行駛時產生含有油污的氣體相互形成混合，且飄散於空氣中，因此該扇葉產生轉動後所形成的氣流，同時這些氣流更會與轉動中的扇葉產生靜電，故當這些雜質在扇葉長期受驅動運轉的擾動後，會受到該靜電的吸引效應而附著在該扇葉上，長期使用過程中若未加以即時清潔處理，會導致污垢在該扇葉上越積越多，除會使積聚在該扇葉之髒污容易隨著轉動之氣流噴射出，有害環境外，並且亦會增加該扇葉運轉時的阻力，導致該扇葉所產生的風量受到影響，實有待改進。According to the investigation, the use of fan blades can not only accelerate the air flow to carry out the mechanism of circulation, of course, the driving performance will be different for different motor sizes, and moreover, in view of the air mixed in daily life Many dust particles, and these dust particles will be mixed with the water vapor in the air, or the gas containing oil when the vehicle is running, and float in the air, so the fan blade generates the airflow formed after rotation, and these The air flow will also generate static electricity with the rotating fan blade, so when the fan blade is disturbed by the driving operation for a long time, these impurities will be attracted by the static electricity and adhere to the fan blade. Cleaning treatment will cause more and more dirt to accumulate on the fan blade. In addition to making the dirt accumulated on the fan blade easily ejected with the rotating airflow, which is harmful to the environment, it will also increase the resistance of the fan blade during operation. , causing the air volume produced by the fan blades to be affected, which really needs to be improved.

因此，本發明之目的，是在提供一種具疏油/疏水之扇葉，其利用防護膜的披覆而成形成一疏油/疏水薄膜層的設置，藉該防護膜可有效防止污垢沾附於上，有效增加該扇葉運轉的順暢與使用壽命的提昇。Therefore, the object of the present invention is to provide an oleophobic/hydrophobic fan blade, which is formed by covering with a protective film to form an oil-repellent/hydrophobic film layer, and the protective film can effectively prevent dirt from adhering In the above, the smooth operation of the fan blade and the improvement of the service life are effectively increased.

參閱圖1，使用時，當該輪轂31受到一該驅動軸的驅動而產生同步的轉動時，該等扇葉片32會隨著轉速的增加而形成有一道氣流，同時該氣流會與轉動中的該等扇葉片32產生微量的摩擦靜電，導致位於該等扇葉片32周圍的粉塵、空氣及其它物質(如水氣、油污等)，即會順著該氣流的流向過程且受到該靜電的吸引效應影響，造成前述該粉塵、水氣或油污等進而往該等扇葉片32處流動，此時鑒於該等扇葉片32及輪轂31上因披覆有該防護膜33設置，故可使該等扇葉片32及輪轂31上得以形成具有疏油/疏水效應功效，所以當粉塵、水氣或油污等受到靜電的吸附時，則會因為該防護膜33的疏油/疏水效應關係，而使粉塵無法沾黏於上，同時對於環境所形成的微細分子如水氣、油污等，也會因該防護膜33而猶如蓮花效應般的無法附著於上，進而免除該等扇葉片32上承載過多的污物而影響運轉速度缺失，使該等扇葉片32、輪轂31達到具有自潔效果功效，當然透過該防護膜33的披覆，更可防止環境中的有害物質對該扇葉3造成傷害與侵蝕，有效提昇該扇葉3使用壽命。Referring to Fig. 1, when in use, when the hub 31 is driven by a drive shaft to rotate synchronously, the fan blades 32 will form an airflow with the increase of the rotational speed, and the airflow will be in contact with the rotating The fan blades 32 generate a small amount of frictional static electricity, causing dust, air and other substances (such as moisture, oil, etc.) around the fan blades 32 to follow the flow of the airflow and be attracted by the static electricity influence, causing the aforementioned dust, water vapor or oil stains to flow to the fan blades 32, at this time, in view of the fan blades 32 and the hub 31 being covered with the protective film 33, the fans The blade 32 and the hub 31 are formed to have an oleophobic/hydrophobic effect, so when dust, water vapor or oil stains are electrostatically adsorbed, the dust cannot At the same time, the micro-molecules formed in the environment, such as water vapor, oil, etc., will also be unable to adhere to the protective film 33 like a lotus effect, thereby preventing the fan blades 32 from carrying too much dirt The lack of affecting the running speed makes the fan blades 32 and the hub 31 achieve a self-cleaning effect. Of course, through the covering of the protective film 33, it can prevent harmful substances in the environment from causing damage and erosion to the fan blades 3. The service life of the fan blade 3 is effectively improved.

以下為本發明披覆有防護膜33之扇葉片32與未披覆有防護膜之習知扇葉片，於相同溫度、相對溼度、水量、油量、塵粒量與時間等條件下，各在運轉60分鐘的環境中，透過不同的轉速實測，其反應結果如下列各表所示：The following are the fan blades 32 coated with a protective film 33 of the present invention and the conventional fan blades not covered with a protective film, under the same temperature, relative humidity, water volume, oil volume, dust particle volume, and time. In the environment of running for 60 minutes, through the actual measurement of different speeds, the reaction results are shown in the following tables:

表1：扇葉片表面水氣附著數據 項目 低轉速 500rpm 中轉速 1,00rpm 高轉速 1,500rpm 習知扇葉片 噴入水量 60g 60g 60g 水滴附著量 0.5211g 0.2323g 0.0881g 本發明 扇葉片 噴入水量 60g 60g 60g 水滴附著量 0.4072g 0.0903g 0.0357g Table 1: Water vapor adhesion data on fan blade surface project Low speed 500rpm Medium speed 1,00rpm High speed 1,500rpm known fan blade Injected water 60g 60g 60g Water droplet adhesion 0.5211g 0.2323g 0.0881g Fan blade of the present invention Injected water 60g 60g 60g Water droplet attachment 0.4072g 0.0903g 0.0357g

因此，請配合參閱圖6A及圖6B，由上述表1之比較可知，本發明披覆有該防護膜33之該扇葉片32，可有效降低水氣在該扇葉片32表面附著量的情形，同時在轉速速度越快時，其附著量更明顯少於習知扇葉片，甚至更趨近於零，由此便可以清楚得知當所處環境中有濕氣、水滴的情況之下，使用披覆有該防護膜33的扇葉片32在長期驅動運轉下，有助於將來可降低水垢與水漬的附著效果。Therefore, please refer to FIG. 6A and FIG. 6B. From the comparison of the above table 1, it can be seen that the fan blade 32 coated with the protective film 33 of the present invention can effectively reduce the amount of water vapor attached to the surface of the fan blade 32. At the same time, when the rotation speed is faster, its adhesion is significantly less than that of conventional fan blades, and even closer to zero. From this, it can be clearly known that when there is moisture and water droplets in the environment, the use of The fan blade 32 coated with the protective film 33 will help reduce the adhesion effect of scale and water stains in the future under long-term driving operation.

表2：扇葉片表面油污附著數據 項目 低轉速 500rpm 中轉速 1,00rpm 高轉速 1,500rpm 習知扇葉片 噴入油量 60g 60g 60g 油滴附著量 0.7471g 0.5414g 0.4302g 本發明 扇葉片 噴入油量 60g 60g 60g 油滴附著量 0.4105g 0.3004g 0.2507g Table 2: Data of oil contamination on the surface of fan blades project Low speed 500rpm Medium speed 1,00rpm High speed 1,500rpm known fan blade Injected oil volume 60g 60g 60g Oil drop attachment 0.7471g 0.5414g 0.4302g Fan blade of the present invention Injected oil volume 60g 60g 60g Oil drop attachment 0.4105g 0.3004g 0.2507g

請配合參閱圖7A及圖7B，由上述表2之比對可清楚得知，鑒於油污的黏滯性比水氣較高，但在轉速速度越快的狀態下，對於本發明披覆有防護膜33之扇葉片32而言，該扇葉片32表面上的油污附著量會明顯減少，由此可知當所處環境是具有濕油氣的情形下，披覆有該防護膜33的扇葉片32在長期運轉使用下，仍可有效大大降低油垢及油漬附著效果。Please refer to Fig. 7A and Fig. 7B. From the comparison of the above table 2, it can be clearly known that in view of the viscosity of oil stains is higher than that of water vapor, but in the state of faster rotating speed, there is no protection for the coating of the present invention. As far as the fan blade 32 of the protective film 33 is concerned, the amount of oil stain adhesion on the surface of the fan blade 32 will be significantly reduced. It can be seen that when the environment is wet with oil and gas, the fan blade 32 coated with the protective film 33 will Under long-term operation and use, it can still effectively and greatly reduce the effect of oil dirt and oil stain adhesion.

表3：扇葉片表面塵粒附著數據 項目 低轉速 500rpm 中轉速 1,00rpm 高轉速 1,500rpm 習知扇葉片 噴入塵粒量 30g 30g 30g 塵粒附著量 1.625g 1.871g 1.913g 本發明 扇葉片 噴入塵粒量 30g 30g 30g 塵粒附著量 0.471g 0.632g 0.869g Table 3: Dust particle adhesion data on fan blade surface project Low speed 500rpm Medium speed 1,00rpm High speed 1,500rpm known fan blade The amount of dust particles injected 30g 30g 30g Dust particle adhesion 1.625g 1.871g 1.913g Fan blade of the present invention The amount of dust particles injected 30g 30g 30g Dust particle adhesion 0.471g 0.632g 0.869g

請配合參閱圖8A及圖8B，因此，由上述表3之比較可知，在轉速速度越快時，其所投入的30克(g)塵粒會於習知扇葉片表面上大約殘留有1.6~1.9克(g)存在，反之，對於披覆有該防護膜33之該扇葉片32表面上，其附著量就明顯降低許多，僅為0.4~0.8克(g)左右；是以，藉該防護膜33的披覆防護可有效防止污垢沾附於上，有效增加該扇葉3運轉的順暢與的使用壽命的提昇。Please refer to Fig. 8A and Fig. 8B, therefore, by the comparison of above-mentioned table 3, we can know that when the rotating speed is faster, 30 grams (g) of dust particles will be left on the surface of the conventional fan blade with about 1.6~ 1.9 grams (g) exists, on the contrary, on the surface of the fan blade 32 covered with the protective film 33, its adhesion is significantly reduced, only about 0.4 ~ 0.8 grams (g); therefore, by this protection The coating protection of the film 33 can effectively prevent dirt from adhering to it, and effectively increase the smooth operation of the fan blade 3 and the improvement of its service life.

歸納前述，本發明具疏油/疏水之扇葉，藉由扇葉上披覆有一防護膜的設置，藉此可使該扇葉有效受到該防護膜作用而達到隔離、披覆，以確實在該扇葉於運轉使用過程中，有效防止外在環境所形成的粉塵、油污及水氣等的附著，避免該扇葉受到過多污垢附著於上而影響運轉，大幅提升使用壽命。To sum up the foregoing, the oleophobic/hydrophobic fan blade of the present invention is provided with a protective film on the fan blade, so that the fan blade can be effectively isolated and covered by the protective film, so as to ensure During the operation and use of the fan blade, it can effectively prevent the attachment of dust, oil and water vapor formed in the external environment, avoid the fan blade from being affected by too much dirt attached to the operation, and greatly increase the service life.
