Abstract

A fan includes a base part and a nozzle mounted on the base part, wherein the base part includes an outlet for outputting airflow; and the nozzle includes an inlet for inputting airflow, an internal cavity for receiving airflow and an exhaust port for outputting airflow. The fan is characterized in that the nozzle can be detached in a manner that the nozzle can horizontally and linearly slide relative to the base part. The nozzle of the fan can be conveniently and reliably detached from or mounted on the base part.

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. But in some cases, this kind of fan also has the danger that the human body touches the group of rotating blades. [0003] On December 7, 2011, the Chinese patent with the authorized announcement number CN101825106 B (application number: 201010130004.3) disclosed a fan without exposed blades. This fan includes a base and a nozzle arranged on the base. The nozzle includes an internal cavity and an exhaust port for re...
