Circulating fan and fan blade group thereof

Abstract

The invention provides a circulating fan and a fan blade group of the circulating fan. The circulating fan at least comprises a shell body, a cover body, and a fan blade group. The shell body comprises a base seat, and the cover body and the shell body are jointed to form containing space. The fan blade group is arranged in the containing space. The fan blade group at least comprises a first impeller, a second impeller, a motor, and a plurality of magnetic components. The second impeller is arranged near the first impeller. The motor is fixedly arranged on the base seat of the shell body and connected with the first impeller to drive the first impeller to run. The magnetic components are arranged between the first impeller and the second impeller. With wind power generated by running of the first impeller and magnetic torque generated by magnetic eddy currents between the magnetic components, the second impeller is driven to run under non-contact force. According to the circulating fan and the fan blade group of the circulating fan, impellers with smaller fan blades are chosen to be used for being matched with the motor with smaller size, and thus effects that the size and power consumption are reduced, space configuration is simplified, and cost is reduced are achieved.
