[ technical field ] A method for producing a semiconductor device

The invention relates to a wind wheel, which aims at a wind wheel of an electric fan and a wind wheel of an airplane, in particular to a ceiling fan.

[ background of the invention ]

Along with the upgrading of an air conditioner and the reduction of electricity price, the life of enjoying the air conditioner is cheaper and cheaper, an electric fan may not be considered in high-level decoration, but the top-level decoration is less than the link of air circulation, so that the electric fan still has needs, but when the fan and the high-level decoration are in a considering and accepting stage, the probability of being abandoned is quite high, the fan is saved and also becomes a partner for the electric fan when the decoration needs are good, however, the top-level villa decoration also has air dust, and as in a flat house and a factory, a thick black ash layer can be adhered to long-time moving fan blades, and although the flat house or the factory is also inelegant and unpopular.

[ summary of the invention ]

The invention aims to realize automatic invisibility and automatic cleaning of fan blades and improve the living space of the electric fan in the air-conditioning era.

The invention utilizes the self-gravity or the counterweight force of the multiple telescopic fan blades to cause the centrifugal force to extend the multiple fan blades and uses the included angle between the telescopic direction of the telescopic fan blades and the central shaft of the hub to be less than 90 degrees to incline, so that the multiple telescopic fan blades are automatically obliquely and slidingly contracted by the self-gravity of the fan blades when the wind wheel is in a stop state, and the automatic cleaning and hiding of the fan blades are completed.

The invention adopts the following technical scheme:

the flexible stealthy flabellum wind wheel of sleeve pipe oblique slip, it includes: a hub and retractable blades; the telescopic fan blades are formed by coaxially sliding, telescopic and sleeving a plurality of large and small sleeves; the telescopic fan blades are fixed on the hub by using a starting end section or a tail end section and movably extend and retract in an annular array around the circumference of the hub; the telescopic fan blades extend out under the condition of self gravity or extend out under the condition of centrifugal force caused by connecting a counterweight at the telescopic tail end section; the included angle between the telescopic direction of the telescopic fan blades and the central shaft of the hub is less than 90 degrees, so that the wind wheel automatically slides and contracts obliquely by means of the self-gravity of the fan blades in a stop state.

In the design scheme of the sleeve oblique sliding telescopic invisible fan blade wind wheel, the multiple sections of large and small sleeves of the telescopic fan blades are flat straight pipes, square straight pipes, prismatic straight pipes, oval straight pipes or arc straight pipes, and the two ends of the pipe orifice are provided with limiting and clamping hasps.

Stealthy flabellum fan of sleeve pipe oblique slip, it includes: the device comprises a sleeve oblique sliding telescopic invisible fan blade and wind wheel set, a power unit and a rack; the telescopic invisible fan blade wind wheel is connected with a rotating shaft or a rotor of the power unit; the power unit is fixed on the frame, or the stator for the power unit is connected on the frame.

The working principle of the invention is as follows: the self-gravity or the counterweight force of the multiple telescopic fan blades is utilized to cause the centrifugal force to extend out the multiple fan blades, and the included angle between the telescopic direction of the telescopic fan blades and the central shaft of the hub is less than 90 degrees, so that the multiple telescopic fan blades are automatically obliquely and slidably contracted by means of the self-gravity of the fan blades when the wind wheel is in a stop state, and the automatic cleaning and hiding of the fan blades are completed.

The invention has the beneficial effects that: the automatic invisibility and the automatic cleaning of the fan blades are realized, and the living space of the electric fan in the air-conditioning era is improved.

The invention is described in further detail below with reference to the following detailed description and accompanying drawings:
