    • An air cleaner including an improved airflow path is provided according to the invention. The air cleaner includes a duct extending between an air inlet of the air cleaner and an air outlet, with the duct being configured to conduct an airflow. The duct includes a shaped input region located downstream of one or more air cleaning components and upstream of an impeller, a curved transition region downstream of the shaped input region, with the curved transition region transitioning the airflow from an air inlet orientation to an air outlet orientation, and an expansion output region downstream of the curved transition region, with the expansion output region allowing the airflow to expand. The air cleaner further includes the impeller located in the curved transition region of the air duct. The airflow is smoothly conducted from the air inlet to the air outlet by the duct.
    • 根据本发明提供了一种包括改进的气流路径的空气净化器。 空气净化器包括在空气净化器的空气入口和空气出口之间延伸的管道,其中管道被配置为传导气流。 管道包括位于一个或多个空气清洁部件下游并且在叶轮上游的成形输入区域,该成形输入区域下游的弯曲过渡区域,其中弯曲过渡区域将空气从空气入口方向转移到空气出口 取向和在弯曲过渡区域下游的膨胀输出区域,扩张输出区域允许气流膨胀。 空气净化器还包括位于空气管道的弯曲过渡区域中的叶轮。 气流通过管道从空气入口平稳地传导到出风口。
