Multi-layer rotating fan

Abstract

The invention relates to the field of fans, and discloses a multi-layer rotating fan which comprises a base, a bottom cover, a supporting column, an outer frame, a fan head, an adjusting mechanism and a blowing mechanism, the bottom of the supporting column is fixedly connected to the center of the top of the bottom cover, the bottom of the outer frame is fixedly connected to the top of the supporting column, the outer frame is annular, and the fan head is cylindrical. The fan head is connected with the outer frame through an adjusting mechanism, a mounting groove is formed in the top of the base, a first servo motor is fixedly connected into the mounting groove, the output end of the first servo motor is fixedly connected with a first rotating shaft, and the top end of the first rotating shaft is fixedly connected to the center of the top of the inner wall of the bottom cover. The fan head can be automatically adjusted to any needed angle in the horizontal direction and the vertical direction conveniently, the flexibility is improved, meanwhile, the automatic adjusting effect can be achieved, manual adjustment of a user is not needed, and the use requirements of people can be better met.

Description

technical field [0001] The patent of the present invention relates to the field of fans, in particular, to a multi-layer rotating fan. Background technique [0002] A fan refers to a device that generates wind and cools in hot weather. An electric fan is a device that uses electricity to drive air flow. After the motor inside is energized, it drives the fan blades to rotate, and the mechanical energy is converted into wind energy, thereby turning into natural wind to achieve a cooling effect. Fans are divided into household electric fans and industrial exhaust fans according to their uses. Among them, household electric fans include ceiling fans, table fans, floor fans, wall fans, ceiling fans, ventilation fans, page turning fans, and air conditioning fans (ie, cooling fans). [0003] Most of the existing common fans are simple in structure, but only have the function of rotating a certain angle on the horizontal plane, and the flexibility is still not high. Although some fa...

Problems solved by technology

[0004] The purpose of the present invention is to provide a multi-layer rotating fan, which aims to solve the problem that most of the existing common fans are simple in structure, but only have the function of rotating a certain angle in the horizontal plane, and the flexibility is still not high, although some fans can rotate in the horizontal plane or vertical plane Rotate upward, but generally it is adjusted by manual rotation, which is inconvenient to operate and cannot meet people's needs well.
