横流风扇，包括横流风扇的电子设备和用于横流风扇的叶轮

Cross-flow fan, electronic device including cross-flow fan, and impeller used for cross-flow fan
Abstract:
A cross-flow fan (10) including a plurality of impellers (11a to 11g) connected in a direction of a rotation axis, each of the impellers (11a to 11g) including: a plurality of blades (12a to 12r); a first connection portion (13) having at least one projection; and a second connection portion (14) having concavities in a larger quantity than the projection, wherein, in a connection between the first connection portion (13) of one of the impellers (11a to 11g) and the second connection portion (14) of another one of the impellers (11a to 11g), the projection of the one of the impellers (11a to 11g) and one part of the concavities of the other one of the impellers (11a to 11g) are fitted to each other in one fitted state among N (N is an integer not smaller than two) ways of fitted states of having a matched rotation axis.
Abstract(Chinese):

一种包括沿旋转轴线方向连接的多个叶轮（11a至11g）的横流风扇（10），每个所述叶轮（11a至11g）包括：多个叶片（12a至12r）; 具有至少一个突起的第一连接部分（13） 以及具有比所述突起大的凹部的第二连接部（14），其中，在所述叶轮（11a〜11g）中的一个的第一连接部（13）与所述第二连接部（14）之间的连接中， 另一个叶轮（11a至11g）中，一个叶轮（11a至11g）和另一个叶轮（11a至11g）的一部分凹凸的突出部分彼此嵌合， N（N是不小于2的整数）的状态具有匹配的旋转轴的拟合状态。
