INTRODUCTION :
As we all know that a table fan has an swivel movement feature which enables it to rotate the blades of the fan in different directions at 180 deg., so that cool air is equally distributed to different corners of the room. We are thinking of a design which will make the fan swivel at any desired angles (<180 deg.) manually.
Controlling The Swivel Movement :
For controlling the swivel movement i.e., to restrict the movement to a specified angle (<180 deg.), we are going to connect a slotted rigid link to the connecting rod. With the help of this slot different angula positions of the swivel movement can be easily obtained and it will swevil under that angular distance only.
ADVANTAGES OF CONTROLLING SWIVEL MOVEMENT :
By this technique swivel movement of the table fan can be controlled at any desired angle.
Minimising the wastage of wind flow generated by the table fan.
