The shortcoming of the above-mentioned conventional one is that the airflow generated when the axial fan rotates is directed to the front of the guide plate of the fixed wing, and thus will be in the blade group and the deflector.

The DC motor or the AC motor are all indispensable, but the present invention uses the DC brushless motor as the power source for driving the axial flow fan blade to meet the power saving green environmental protection effect, and the foregoing power component 1 is fixed to the flow guiding component. After 3, the safety net 31 is coupled to the slot 310 and fixed by the bolting member 11 (see Figs. 2 and 3).
於前述動力元件1之心軸10設置有軸流扇葉2(如圖2及3),前述心軸10與軸流扇葉2之結合本屬習知技術,因此,不再贅述。前述軸流扇葉2設複數葉片20,前述葉片20之最外周緣200之弧度R係相等或接近於導流元件3之內導流壁32之弧度R(如圖3~5),並讓前述葉片20之最外周緣200得以與導流元件3之內導流壁32形成最小的間距d,其目的乃是得以減少氣流於導流元件中發生逆流,致生亂流現象,影響氣流輸出穩定性,更得以增加輸出風量與氣流進入室內或環境空間之距離。 The mandrel 10 of the power element 1 is provided with an axial fan blade 2 (see FIGS. 2 and 3). The combination of the mandrel 10 and the axial fan blade 2 is a prior art and therefore will not be described again. The axial fan blade 2 is provided with a plurality of blades 20, and the arc R of the outermost peripheral edge 200 of the blade 20 is equal to or close to the curvature R of the inner deflector wall 32 of the flow guiding member 3 (see Figs. 3~5), and The outermost peripheral edge 200 of the blade 20 is formed with a minimum distance d from the inner guiding wall 32 of the flow guiding element 3, the purpose of which is to reduce the backflow of the airflow in the flow guiding element, causing turbulence and affecting the airflow output. Stability also increases the amount of output airflow and airflow into the indoor or environmental space.

The inner flow guiding member 3 is provided with an inner guiding wall 32 (as shown in FIGS. 7A, 7B and 7C). The inner guiding wall 32 is provided with a larger opening at the air inlet 33, and the air outlet 34 is provided with a small opening, that is, an air flow. The inner diameter of the inlet 33 is larger than the inner diameter of the air outlet 34 to form a reduced state, allowing a large amount of airflow to quickly enter the flow guiding member, thereby being concentrated and guiding the airflow direction, thereby reducing the resistance and increasing the flow rate of the airflow.

The guide vanes 4a are formed as separate components and are integrated with the aforementioned flow guiding elements 3. The purpose of the foregoing guide vanes is to guide the airflow from the airflow outlet 34 to generate a cyclone force, thereby prolonging the output distance of the airflow and improving the indoor airflow circulation effect.
如此,本發明於運用上,得於前述軸流扇葉2之複數葉片20之最外周緣200之弧度R相等或接近於導流元件3之內導流壁32之弧度R(如圖3~5),並讓前述葉片20之最外周緣200得以與導流元件3之內導流壁32形成最小的間距d,以讓軸流扇葉2與導流元件3之內導流壁32產生相等或近似弧度與相等距離之技術特徵,具有增加氣流量,且於導流元件3得以減少亂流之產生,並增長氣流輸出距離之優點。或於軸流扇葉2與導流元件3之內導流壁32產生相等或近似弧度與相等距離之技術特徵外,於導流元件3之氣流出口設導流葉片4,得以將導流元件內部之氣流順利導引進入室內或使用空間中,延長氣流之輸出距離,提升本循環扇作為室內溫度調節之效果,為本案之組成。 扇作為室內溫度調節之效果,為本案之組成。 Thus, in the application, the curvature R of the outermost periphery 200 of the plurality of blades 20 of the axial fan blade 2 is equal to or close to the curvature R of the inner guide wall 32 of the flow guiding element 3 (see FIG. 3~ 5) and allowing the outermost peripheral edge 200 of the blade 20 to form a minimum spacing d with the inner guide wall 32 of the flow guiding element 3 to allow the axial flow fan 2 and the inner flow guiding wall 32 of the flow guiding element 3 to be generated. The technical features of equal or approximate radians and equal distances have the advantage of increasing the air flow and reducing the turbulence in the flow guiding element 3 and increasing the airflow output distance. Or in the axial flow fan blade 2 and the inner guide wall 32 of the flow guiding element 3 to produce the same or similar arc and equal distance technical features, the flow guiding element 3 at the air flow outlet is provided with the guide vane 4, the flow guiding element The internal airflow smoothly guides into the indoor or use space, prolongs the output distance of the airflow, and enhances the effect of the circulating fan as the indoor temperature adjustment, which is the composition of the case. The effect of the fan as an indoor temperature adjustment is the composition of this case.
