Abstract

The invention discloses a fan component comprising a nozzle and a fan. The fan is used for generating airflow in the nozzle. The nozzle comprises an inner channel and a mouth portion. The mouth portion is communicated with the inner channel and used for spraying the airflow. The fan comprises a frame, a vane wheel pivoted at the center of the frame and a motor driving the vane wheel. The motor is suspended on one side of the frame and comprises a speed increasing mechanism. Through the speed increasing mechanism, the fan component can use the motor with low revolving speed to acquire high-speed rotation of the vane wheel. On the requirement of generated air quantity satisfying revolving speed of the vane wheel, requirements on the revolving speed of the motor are reduced, so that service life of the motor is prolonged and production cost of the motor is reduced. In addition, vibration noise of the motor is reduced through suspension of the motor.

Description

technical field [0001] The present invention relates to an electric fan, in particular to a fan assembly without blades, which includes a nozzle and a fan for generating airflow in the nozzle; the nozzle includes an internal channel and communicates with the internal channel and sprays Airflow mouth. Background technique [0002] Bladeless electric fans are becoming more and more popular in the market because of their better safety and unique air outlet mode. The wind of this type of fan needs to be generated by the rotating impeller hidden in the base. For example, the Chinese utility model patent with the notification number CN201884311U discloses a fan assembly for generating airflow, and the fan assembly includes a nozzle installed on a base. The base includes an outer housing; an impeller housing housed within the outer housing, the impeller housing having an air inlet and an air outlet; an impeller within the impeller housing; and driving the impeller to generate air...
