The fan protection net is arranged on the outermost side of the fan fixing seat 21 and used for protecting electric elements such as the internal fan blade 20 and the fan driving motor 18. The fan fixing seat 21 is of a special-shaped structure with a cylinder at one end and a square cylinder at the other end, the cylinder is coaxially arranged corresponding to the fan blade 20, and the square cylinder is convenient for fixed connection.

When the butterfly window 14 needs to be opened, the control panel 2 is controlled by an external operation control panel to control the double-shaft motor 1 to rotate reversely to drive the rotating shaft to rotate reversely so as to drive the crank 5 and the connecting rod to do relative motion, the rotary displacement of the rotating shaft is finally converted into the closed motion displacement of the butterfly window 14, the butterfly window 14 is continuously closed along with the rotation of the rotating shaft, when the butterfly window 14 is completely closed, the wind force blocking of the fan is converted into a linear blocking through the surface blocking, the blocking effect can be almost ignored, at the moment, the limiting part 3 fixed on the rotating shaft just touches the trigger button on the microswitch 4, the micro switch 4 controls the double-shaft motor 1 to stop rotating; when the butterfly window 14 needs to be closed, because the fan blade 20 continuously rotates for a period of time due to the inertia effect, the system delays 2 seconds to send a start signal to the control board 2 to ensure that the fan blade 20 and the butterfly window 14 are finally synchronously closed, the control board 2 controls the dual-shaft motor 1 to rotate to drive the main shaft to rotate, further drive the crank 5 and the connecting rod to do relative motion, the rotation displacement of the main shaft is finally converted into the movement displacement for opening the butterfly window 14, the butterfly window 14 is continuously unfolded along with the rotation of the main shaft, when the butterfly window 14 is completely unfolded, the fan blowing window is just blocked, at this time, the limiting part 3 fixed on the rotating shaft just touches the trigger button on the micro switch 4, the micro switch 4 controls the dual-shaft motor 1 to stop rotating, the control board 2 can also control the dual-shaft motor 1 to stop rotating, but the control board 2 controls the operation duration of, time control can have certain delay or deficiency compared with mechanical touch control, lead to butterfly window 14 not to expand totally closed or excessively expand excessively closed, time control is not as sensitive as mechanical touch's control, but still remain time control module in control panel 2, when preventing that micro-gap switch 4 from breaking down, locating part 3 rotates for a long time and leads to the emergence of the wearing and tearing condition, time control sets for longer than mechanical touch control time usually, give certain interference time and be favorable to protecting executor 15 to avoid damaging biax motor 1.

The above detailed description of the present invention is only a preferred embodiment of the present invention, and the scope of the present invention should not be limited thereto, i.e. all the equivalent changes and modifications made according to the scope of the present invention should be covered by the present invention.
