A pair cooperate when, can drive first rotating shaft 2 rotate i.e. flabellum rotation.
The reference diameter of the first gear 4 is less than the reference diameter of second gear 5, the reference circle of second gear 5
Diameter is less than the reference diameter of third gear 6.1 outer wall of casing is equipped with temperature sensor, and the temperature sensor is in
Module is controlled to be electrically connected.
1 lower part of casing is equipped with runner assembly, and the runner assembly includes third motor 22, outside the third motor 22
It is electrically connected with third motor drive module, the third motor drive module and middle control module are electrically connected, the third electricity
Machine 22 is externally provided with pedestal 25, and it is solid that the third motor 22 is set to 25 inside of pedestal and 22 top of third motor and 1 outer surface of casing
Fixed connection, the pedestal are equipped with speech recognition module, and the speech recognition module and middle control module are electrically connected.
Concrete operating principle: when the starting of the second motor 12, with the rotation of the second motor 12, first pulley 13 is driven to send out
Raw rotation, first pulley 13 is cooperatively connected with the second belt wheel 15 by conveyer belt 14, therefore first pulley 13 drives the second belt wheel 15
It rotates, when the rotation of the second belt wheel 15, the 4th gear 7, the 5th gear 8 and the 6th gear 9 in the second shaft 3 occur together
Step rotation can drive first rotating shaft 2 when the gear on the gear of the second shaft 3 and first rotating shaft 2 has a pair of cooperate
Rotate i.e. flabellum rotation.When first motor 19 starts, half gear 18 is driven to rotate, and half gear 18 and rack gear 17
It is cooperatively connected, when first motor 19 rotates clockwise, half gear 18 is rotated synchronously, when the teeth on half gear 18 are located above
When, drive connecting plate 16 to move right, when moving on to right end, half gear 18 and the rack gear 17 of lower section start to cooperate, and at this time the
Two gears 5 and the 5th gear 8 are completed to cooperate, and flabellum is driven to complete rotation；Half gear 18 continues to rotate clockwise, and drives connecting plate
16 are moved to the left, and during being moved to the left, second gear 5 is gradually disengaged with the 5th gear 8, first gear 4 and the 4th gear 7 by
Gradually cooperate；Half gear 18 continues to rotate, and drives connecting plate 16 to be gradually moved into left end, at this time first gear 4 and the 4th gear 7
It is gradually disengaged, third gear 6 gradually cooperates with the 6th gear 9, drives the tooth in first rotating shaft by the gear in the second shaft 3
Wheel rotation, drives flabellum to rotate with this, since the radius of the 6th gear 9, the 4th gear 7 and the 5th gear 8 is different, so, wind
The revolving speed of fan can also change.When third motor 22 starts, casing 1 is driven to swing, the perception of temperature sensor moment
Room temperature, when room temperature is higher, temperature signal is passed to middle control module by temperature sensor, and middle control module makes instruction
Start first motor 19, so that half gear 18 is rotated, adjust the wind speed of fan, carries out yaw if necessary to fan, can pass through
" swing " two word is said, after speech recognition module identifies " swing ", third motor 22 is started by middle control module, keeps fan complete
At yaw, the cooperation of sliding slot 20 and sliding block 21 ensure that the second shaft 3 during moving left and right, and the second belt wheel 15 is always positioned at
The surface of first pulley 13 can cooperate with first pulley 13.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
