Abstract

The invention provides a circulating fan and an air ducting of the circulating fan. The circulating fan at least comprises a shell body, a cover body, an air ducting, driven blades and driving blades. The cover body is arranged to joint with the shell body to form containing space. The air ducting is arranged on the cover body and at least comprises an air guiding cover and a magnetic resistance structure which is arranged on the cover body and the air guiding cover. The driven blades are arranged in the containing space. The driving blades are arranged in the containing space and near to the driven blades to generate wind power to drive the driven blades and the air guiding cover to rotate. Magnetic torque is generated by magnetic eddy currents of the magnetic resistance structure to slow down the rotation speed of the air guiding cover. The driven blades and the air guiding cover are driven by wind power generated by the driving blades, and rotation speed of the air guiding cover is adjusted through the magnetic resistance structure to optimize air guiding effects, so effects that air circulation efficiency is improved, energy is saved, space configuration is simplified, and cost is reduced are achieved.

Description

technical field

[0001] The invention relates to a circulation fan, in particular to an automatic guiding energy-saving circulation fan and an air guidance device which uses a magnetic resistance damping structure to adjust the best air guidance effect. Background technique

[0002] In recent years, with the rising awareness of environmental protection, energy conservation and carbon reduction policies have become the goal of public agencies and even private companies to strengthen research. Summer electricity saving is the current goal of global improvement and innovation. Therefore, organizations, enterprises, schools, and families have all begun to focus on reducing the frequency and time of air-conditioning use. In order to maintain air circulation and promote space utilization, various fans, circulation fans, and other products have begun to appear on the market. .

[0003] Most of the existing circulation fans directly use the motor to drive the fan blades and the air ...
