Description

technical field [0001] The invention relates to a fan. In particular, but not exclusively, the present invention relates to a domestic fan, such as a domestic desk fan, for increasing air circulation and air flow in homes, offices and other environments. Background technique [0002] A traditional household fan typically consists of a motor and a set of blades or impellers that are driven in rotational motion by the motor. The set of blades is typically located within a cage that allows airflow to pass through, yet prevents human access to the rotating blades. However, in some cases, there is a risk that the human body may touch the set of rotating blades in this fan. [0003] The Chinese patent with the authorized announcement number CN 201568346 U on September 1, 2010 describes a fan, which includes a base, a nozzle and an air duct support; the base includes an outer shell, an impeller contained in the outer shell shroud, an impeller located in the impeller shroud and a...
