Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, various embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, those skilled in the art can understand that in each implementation manner of the present invention, many technical details are proposed in order to enable readers to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solution claimed in each claim of the present application can be realized.

[0023] The invention relates to a double-layer variable speed fan, such as figure 1 As shown, the double-layer variable-speed fan includes a fixed end 1, a power cord 2, a connecting rod 3, a stator end, a driving motor, a rotating cover 5, and fan blades 6. The fixed end 1 can be a lifting ring or a fixing clip, which can be se...

Abstract

The invention relates to a double-layer type speed variable fan. The double-layer type speed variable fan comprises a fixing end, a power cord, a connecting rod, a stator end, a driving motor, a rotating cover and fan blades; the fixing end is connected with the stator end through the connecting rod, the stator end and the rotating cover are correspondingly connected with the driving motor, and the power cord is connected with the driving motor; the fan blades are inserted into inserting grooves in the rotating cover through a plug for fixedly mounting; N of inserting grooves are formed in therotating cover; and a wind blowing device is arranged between the stator end and the driving motor. According to the double-layer type speed variable fan, a rotating motor is added on the basis of one original driving motor, the wind blowing function with different wind forces can be provided by controlling and using the driving motor or the rotating motor or simultaneously using of the two driving motors during using, so that the purpose of changing of the wind speed is achieved under the circumstance of not adjusting the rotating speed.

Description

technical field [0001] The invention relates to the field of home appliances, in particular to a double-layer variable-speed fan. Background technique [0002] A kind of miniature ceiling fan is arranged on the market at present, because this ceiling fan structure is simple, and cost is lower, so have good market. But because this ceiling fan is driven by a permanent magnet synchronous AC motor, although there is a better energy-saving effect, the rotating speed is relatively single, so the rotating speed cannot be adjusted, and the wind speed cannot be better changed during use. Therefore, in order to solve the above problems, the prior art needs to be improved. Contents of the invention [0003] The purpose of the present invention is to provide a double-layer variable speed fan, which solves the problem that the wind speed cannot be changed without adjusting the speed. [0004] In order to solve the above technical problems, the embodiment of the present invention pro...
