相关申请
本申请要求2018年10月15日申请的，申请号为201811195428.0，名称为“气流转换装置及包括其的吸尘器”的中国专利申请的优先权，在此将其全文引入作为参考。
技术领域
本申请涉及气流驱动设备相关技术领域，特别是一种气流转换装置及包括其的吸尘器。
背景技术
吸尘器通过负压形成吸力，将一些区域内的尘污吸入到指定腔体内，达到清洁的作用。相对普通扫把等打扫工具清洁效果更好，越来越受到大众的喜欢。但一些区域的尘污因为一些原因(如被遮挡或粘附)，导致靠现有吸尘器无法去除此尘污，所以就出现了一些具备吹尘功能的吸尘器，这些类型机器一般都是利用电机的排风口来进行吹风，这种结构最大的缺点是，因为吹尘风道仍是连接到原来的吸尘风道，致使吹出的风中会含有污尘，会导致二次污染。同时因为出风风道变长，增加风阻，电机会受热，导致电机寿命缩短，使得吸尘器的结构更加复杂，造价更高。
