Axial flow fan, motor assembly and blower
The invention provides an axial flow fan, a motor assembly and a blower, the axial flow fan comprises a hub, an air guide part and a fan blade group, the length on the rotating axis is defined as the height, the fan blade group comprises a plurality of first fan blades and a plurality of second fan blades, the first fan blades are provided with first root parts connected with the hub and first tail parts far away from the hub, and the second fan blades are provided with second tail parts far away from the hub; the second fan blade is provided with a second root part connected with the hub and a second tail part far away from the hub; observed along the rotating axis, the first root part and the air guide part at least partially coincide, and the second root part and the air guide part at least partially coincide; the height of the first root part is smaller than that of the first tail part, the height of the second root part is smaller than that of the second tail part, and the height of the first root part is smaller than that of the second root part. The heights of the second roots of the first fan blade and the second fan blade are small, so that an undisturbed negative pressure space can be formed near the rotating axis, and the wind resistance can be reduced and the air outlet amount can be increased; the height of the second root portion is larger than that of the first root portion, and it is guaranteed that the axial flow fan has enough strength.
本申请提供一种轴流风扇、电机组件及吹风机，轴流风扇包括轮毂、导风部及扇叶组，在转动轴线上的长度定义为高度，扇叶组包括多个第一扇叶和多个第二扇叶，第一扇叶具有连接轮毂的第一根部及远离轮毂的第一尾部，第二扇叶具有连接轮毂的第二根部及远离轮毂的第二尾部；沿转动轴线观察，第一根部与导风部至少部分重合，第二根部与导风部至少部分重合；第一根部的高度小于第一尾部的高度，第二根部的高度小于第二尾部的高度，第一根部的高度小于第二根部的高度。第一扇叶及第二扇叶的第二根部的高度较小，有利于在转动轴线附近形成无扰动的负压空间，有利于减小风阻提高出风量；第二根部较第一根部具有更大的高度，保证轴流风扇具有足够的强度。
