Abstract

The invention relates to an impeller. The impeller comprises an impeller body and a protection cover. The impeller body comprises a hub and a plurality of blades, wherein the hub is roughly conical, and the blades are connected to the hub. The protection cover is connected to the outer side edges of the blades and comprises a shell, a sound attenuation component and at least one through hole, wherein the shell is provided with an internal cavity, the sound attenuation component is located in the internal cavity, and the through holes are formed in the shell. The invention further provides a fan with the impeller. The impeller or the fan is low in noise.

Description

technical field [0001] The invention relates to an impeller and a fan with the impeller. Background technique [0002] A traditional household fan usually includes an impeller rotating around a central shaft and a motor driving the impeller to rotate. The impeller is usually located within a cage that allows air flow through the housing, yet prevents the user from accessing the spinning impeller when the fan is in use. [0003] Bladeless fans, which have only been commercialized in recent years, do not use a caged impeller to project airflow from the fan. A bladeless fan usually includes a base and a nozzle arranged on the base, and a motor-driven impeller is arranged in the base, and the impeller includes a generally conical hub with a central shaft hole and is connected to the hub. This type of impeller usually requires high-speed rotation, and its maximum speed is as high as 8000 rpm. [0004] This kind of impeller has the characteristics of easy forming and high produ...
