Abstract

A bladeless fan comprises a spray nozzle and a generation device for generating air flow passing through the spray nozzle. The spray nozzle comprises a cavity and a venting hole, the generation device comprises an impeller cover, impellers arranged in the impeller cover, a motor for driving the impellers to work, a fixing device for fixing the motor, and a cable connected with the motor, wherein the fixing device comprises a first fixing piece connected with the motor and a plurality of connecting rods, one end of each connecting rod is connected with the first fixing piece, and the other end of each connecting rod is connected with the impeller cover. The bladeless fan has the advantages of being low in air flow transmission loss, simple in structure and the like.

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] The Chinese patent application with publication number CN 101825105A published on September 8, 2010 (application number: 201010130001.X) discloses a fan without exposed blades, which includes a base and a nozzle installed on the base. The base includes an outer shell and a generating device for ...
