What is the expansion angle of the folding fans of different specifications?

I wanted to do this article about the "expansion angle of the fan.com/Products/Foldingfan/ target=_blank class=infotextkey>Folding fan" for a long time. Today, I finally took a little time to briefly talk about it and try to explain it as clearly as possible! I hope it will be helpful for you to understand the fan.com/Products/Foldingfan/ target=_blank class=infotextkey>Folding fan!

What factors are related to the unfolding angle of a fan.com/Products/Foldingfan/ target=_blank class=infotextkey>Folding fan? Let’s take a look.

Number of ossicles: Others are the same, the number of ossicles is large, and the angle of expansion is large

Discharge port: Others are the same, the discharge port is large, and the expansion angle is large

The length of the fan.com/Products/Foldingfan/ target=_blank class=infotextkey>Folding fan: the others are the same, the length is short, and the unfolding angle is large

Eye position: Others are the same, the eye position is long, and the expansion angle is large (the eye position has little effect)

However, the specifications of the fan.com/Products/Foldingfan/ target=_blank class=infotextkey>Folding fans are basically fixed. For a more intuitive display, I will use pictures to show the most common sizes and deployment angles of several fan.com/Products/Foldingfan/ target=_blank class=infotextkey>Folding fans on the market.

9.5 inch 18 square, outlet 2.0, unfolding angle 133 degrees

9 inch 13 square, outlet 2.5, unfolding angle 120 degrees

8 inch 15 square, outlet 3.0, unfolding angle 170 degrees

The above are some examples of specifications, how to choose the size of the fan.com/Products/Foldingfan/ target=_blank class=infotextkey>Folding fan bone, men and women are different, the height is also different, and the preferences are even different. In ancient times, bras and belly were emphasized, that is to say, military generals should use a large fan, and if they want more than one foot, they should fan their belly. The literati should use one foot or less, and the convening angle should be lower than 90 degrees. Even if it is completely greater than 90 degrees, it cannot be fully unfolded during use. When fanning the chest, leave a few strands that are not unfolded, making it look less than 90 degrees. ancient sayings. But now people don't pay much attention to it, and they choose completely according to their personal preferences. Currently, the most specifications on the market are 9.5-inch 18-square 2.0 and 9.5-inch 16-square 2.0. The expansion angle of the former is about 133 degrees, and the latter is 120 degrees. degrees, these two

This specification is also the most popular among players. According to the golden ratio, 360*(1-0.618)=137.52 degrees. This degree is the most comfortable degree. It seems that players favor these two specifications. It's not unreasonable

Similarly, the open shoulders of fan.com/Products/Foldingfan/ target=_blank class=infotextkey>Folding fans are also the same. The most common open shoulders are six or four bays (the length of the fan is 6, and the excess is 4). Well, that's all I've said this time. I hope you will have a certain understanding of the unfolding angles of various specifications of fan.com/Products/Foldingfan/ target=_blank class=infotextkey>Folding fans in the future. Next time the seller tells you the specifications of the fan.com/Products/Foldingfan/ target=_blank class=infotextkey>Folding fan, you can know this fan.com/Products/Foldingfan/ target=_blank class=infotextkey>Folding fan more clearly in your mind. How big it will be after expansion, so as to make a more rational decision.
