Embodiment Construction

[0022] specific implementation plan

[0023] The frame 7 is fixedly connected with the roof through the through hole 9 arranged on its top. The long axis of the motor 8 directly drives the fan leaf to rotate. The rocking rod 4 is connected, and the other end of the rocking rod 4 is connected with the pinion shaft 3 through a cotter pin, and the pinion shaft 3 is fixedly connected with the V-shaped plate 2 . The pinion gear meshes with the bull gear, and the bull gear shaft 1 is fixed on the top frame 7.

[0024] After the motor rotates, both the long shaft 10 and the short shaft at the tail end of the motor start to rotate, and the short shaft at the tail end drives the oscillating head output shaft 11 to rotate after being decelerated by the deceleration device, and the oscillating head output shaft 11 drives the rocker 4 to rotate, and the rocker 4 drives the pinion The shaft 3 rotates, and the pinion shaft 3 revolves around the fixed large gear shaft 1 while rotating, so a...

Abstract

The invention relates to a fan, in particular to a structure of a ceiling type fan. A universal ceiling type fan comprises a motor, a frame and a supporting bracket. The supporting bracket is fixedly connected at the bottom of the frame. The motor is rotatably connected on the supporting bracket through a rotary shaft. The universal ceiling type fan further comprises a head shaking device which is a set of two-gear linkage structure. The numbers of teeth of two gears are respectively an odd number and an even number. According to the universal ceiling type fan provided by the invention, the odd number is matched with the even number so that each ring of a pinion rotating around a rack wheel is slightly different than before in position. The target of non-dead angle full coverage wind supply in an angle range is finally realized, and the wind supply coverage is improved by more than 50% compared with that with a previous angle range.

Description

technical field [0001] The invention relates to an electric fan, in particular to a ceiling fan. [0002] technical background [0003] The air supply range of ceiling fans on the market today is limited, and it cannot meet the needs of places that require a larger range of air supply, such as student dormitories and warehouses. [0004] Contents of the invention [0005] The purpose of the "universal ceiling fan" of the present invention is to propose a ceiling fan capable of large-area air supply without dead ends. [0006] To achieve the above object, the present invention mainly includes following technical solutions: [0007] The universal ceiling fan includes a motor, a frame and a support frame, the support frame is fixedly connected to the bottom of the frame, the motor is rotatably connected to the support frame through a rotating shaft, and a gear linkage device is also included. The gear linkage device includes a set of two gear linkage structures, and the n...
