Description

Automatic rotating mechanism of circulating fan Technical Field The utility model relates to the technical field of fans, in particular to an automatic rotating mechanism of a circulating fan. Background The circulating fan is an electric equipment capable of promoting the efficient circulating flow of indoor air, and is different from the traditional fan which brings local cooling sense only by blowing, and strong and concentrated spiral air flow is formed by unique design of large-inclination-angle spiral fan blades, directional diversion wind covers and the like, so that the indoor air is rapidly stirred, the static and layered states of the air in a space are broken, and the cold air and the hot air are rapidly and uniformly mixed. At present, the existing circulation fan is usually required to be manually pulled to adjust when adjusting the blowing angle, and although the basic blowing direction can be changed, the existing circulation fan cannot be automatically adjusted to a proper angle in real time and accurately according to the actual use situation, the operation process is time-consuming and labor-consuming, the ideal effect is difficult to achieve, and a user is difficult to quickly obtain proper blowing experience under different environments. Disclosure of utility model The utility model aims to solve the defect that in the prior art, a proper blowing experience is difficult to obtain quickly by a user in different environments because the automatic rotating mechanism of the circulating fan cannot be accurately and automatically adjusted to a proper angle in real time according to actual use scenes.
