Wherein since the first drive rod 6 and the second drive rod 7 are all columned, such first drive rod 6 and second drives
In the rotation, opposite movement occurs lever 7 for extraneous air and the first drive rod 6 and the second drive rod 7, cylindric to make
The outer surface of the first drive rod 6 and the second drive rod 7 can be preferably applied to by obtaining air, so as to accelerate the first drive rod
6 and the second drive rod 7 heat distribute speed；Wherein the first drive rod 6 is that the second drive rod 7 is pushed to rotate in the rotation
, i.e. the second drive rod 7 is located at before 6 direction of advance of the first drive rod, and this makes it possible to cause the first drive rod 6 and second
Connection that can be relatively stable between drive rod 7 rather than the first drive rod 6 drag 7 activity of the second drive rod, while are connecting
The two edge need to only be welded when the first drive rod 6 and the second drive rod 7, without in the first drive rod 6 or the second
Punching is attached on drive rod 7, not only so that actual processing production is more simple and convenient, simultaneously because the first drive rod 6 pushes away
When dynamic second drive rod 7 rotation, the activation force of the two is born by the structure of the two rather than passes through weldering
The structure connect is born, the connection that such first drive rod, 6 and second drive rod 7 just can be more stable.
First drive rod 6 is the edge for being connected to drive disk 5, so the first drive rod 6 is driving 7 turns of the second drive rod
When dynamic, the power arm that the first drive rod 6 has is just maximum, causes in the case where vane rods 3 are by identical torque magnitude
The Interaction Force smaller of first drive rod 6 and the second drive rod 7, it is therefore prevented that situations such as the two deforms.
There is cylindric transmission cylinder 8 on 3 top of vane rods, since 8 middle part of transmission cylinder is hollow-core construction, so working as heat
After being transmitted on transmission cylinder 8, there is the gross contact area of bigger, so that heat distributes between transmission cylinder 8 and the external world
Faster and more, while the heat of the second drive rod 7 is transmitted to also with regard to less；And since the diameter of transmission cylinder 8 is greater than blade
Bar 3, so when the second drive rod 7 is rotated with same drive force transmission cylinder 8, the transmission cylinder 8 of diameter bigger adds
The big power arm of second drive rod, 7 driving blade bar 3 rotation, so just can preferably reduce what the second drive rod 7 was subject to
Torque magnitude plays protective effect to the second drive rod 7.Due to being to pass through driving groove between the second drive rod 7 and transmission cylinder 8
It carries out, since the second drive rod 7 is to contradict the inner wall in driving groove so that transmission cylinder 8 to be driven to rotate, i.e., the second drive rod 7 is with passing
No welding or integrally formed between dynamic cylinder 8, so there is certain gap between the second drive rod 7 and transmission cylinder 8, this
Sample can be reduced further when heat is transmitted to from transmission cylinder 8 on the second drive rod 7.
There is the distance of 9cm between 5 middle part of vane rods 3 and drive disk, so when heat distributes it from 3 top of vane rods
Afterwards, the distance of 9cm can also cause the smaller effect for receiving heat radiation of drive disk 5；Have one between drive disk 5 and motor bar 2
A angle, usual level switch are also to use vertically, so the corner dimension between drive disk 5 and motor bar 2 is also just to drive
The angle of Moving plate 5 and gravity direction, simultaneously because the air with higher temperature all flows up, so when air is vertical
When flowing up, inclined drive disk 5 enables to hot-air conveniently to flow through, convenient for distributing for heat, simultaneously
Uptake of the drive disk 5 to the heat of the hot-air of rising is decreased, it is highly practical.
