The invention provides a fan blade, a fan and an air conditioner. The fan blade comprises a blade body (1), a leading edge point and a trailing edge point of an airfoil profile are formed by intersection points of an airfoil profile center line of the blade body (1) and an airfoil profile contour line, the linear distance between the leading edge point and the trailing edge point is C, a convex hull (2) is arranged on the airfoil profile surface of the blade body (1), and the convex hull (2) is arranged in the area range of 0.25 C of the center line, close to the trailing edge point, of the airfoil profile surface. According to the fan blade, the energy gradient of the near-wall area on the airfoil surface can be reduced, the consumption of turbulent kinetic energy is reduced, the energy loss in the flowing process is reduced, the power capability is improved, and the energy consumption is reduced. 本发明提供了一种风机叶片、风机和空调器。该风机叶片包括叶片本体(1)，叶片本体(1)的翼型中线与翼型的轮廓线的交点形成翼型的前缘点和尾缘点，前缘点和尾缘点之间的直线距离为C，叶片本体(1)的翼型表面设置有凸包(2)，凸包(2
