History of the Bladeless Fan
To all consumers and colleagues:
I'm a Bladeless Fan (also recognized as a no Leaf, hidden leaf or no hakaze fan). I was developed in China in 2009 by Liang Shi FU.
By way of history of creation:
1. The first ever bladeless fan in the world was initially curated in 1980 in Tokyo by Toshiba. Toshiba invented the first non-blade fan in the world’s history. On May 29, 1980 Toshiba ascertained the invention patent. The patent on December 23, 1981 was announced to the world, with a validity time of 20 years, which expired on December 23rd 2001 (ref: Japanese Original patent doc. Patent NO: 昭56-167897).
The initial concept of the first bladeless fan, was what instigated the ideal for Liang Su Fu to further develop the bladeless fan design incorporating the air outlet ring into the structure of the fan body, as well as adding the the flip up and down, and rotate left and right function.
2. Another integral component and development of the Fan is the Shroud with air supply, which was first developed in March 16th 1999 (US John F. foss got patent of fan shroud with integral air supply-with patent doc. Patent No.:5881685).
3. Followed by the advancement of Exhaust Fan System (Date of Patent: Feb.3,2009. Inventor: Erich R.Fitzpatrick. Patent No.:US7484929 B1).
4. Most recognizable in the development history of the Bladeless fan is the creation of Dyson fans. Established on October 12th 2009 by British creator James Dyson. Dyson introduced a new non-leaf fan; called Dyson Air Adders. Subsequently Dyson secured the patent in China.
5. Dyson commenced litigation with “Liang San FU” in 2014. It was in December 2016, which Liang San Fu finally and successfully won against Dyson, and was issued a fair judgment from the Supreme Court of China to freely manufacture and sell their Bladeless Fan.
6. Furthermore to successfully winning the patent law suit against Dyson, on January 24th 2017, Liang San Fu applied to invalidate Dyson original patents to the Chinese National Patent office, and very successfully has invalidated 95% of Dyson’s Patents (No.1-13, and 15-17).
Liang San Nu is now successfully paving the way in being the NEW industry leader in innovation, and quality in the Bladeless fan Industry.
