    • The present invention relates to a ceiling fan blade capable of producing full wind pressure and much wind. The solution of the present invention is to form a front and a rear wind receiving surfaces on the ceiling fan blade. A tangent angle of the rear wind-receiving surface is bigger than that of the front wind-receiving surface. A wavy wind guide surface is formed between the two wind receiving surfaces. The wavy wind guide surface and the two wind receiving surfaces can effectively increase the wind pressure and the wind; in addition, sinuous flow is substantially reduced when the blade is rotating.
    • 本发明涉及一种能够产生全风压和大风的吊扇。 本发明的解决方案是在天花板风扇叶片上形成前后风力接收表面。 后风收容面的切线角大于前受风面的切角。 在两个风力接收表面之间形成波浪形的导风表面。 波浪导风面和两个受风面可以有效地增加风压和风; 此外,当叶片旋转时,弯曲流动显着减小。
