What is the principle of the anti-fog mask invented by primary school students?

The principle of the anti-fog mask invented by Wang Kangyu, a pupil, is to add an arc-shaped "air barrier" on the basis of the original mask and stick it on the bridge of the nose in the opposite direction, so that the upward exhaled air can press the "air barrier" to stick it on the skin to prevent the exhaled air from rushing to the lens and fogging.

According to reports, the sixth-grade student named Wang Kangyu is from Huai 'an, Jiangsu. During the epidemic, he saw on TV that Zhong Nanshan's glasses were foggy when he was interviewed, so he decided to invent an anti-fog mask.

On February 14 this year, Wang Kangyu obtained the Notice of Patent Acceptance Application from China National Intellectual Property Administration and donated it to a mask manufacturer for free. He said: "I want to contribute to the epidemic, so I want to apply for a patent. This mask is produced to help more people. "

Compared with the primary school students who won the national science and technology competition some time ago, many netizens are full of praise. This is based on their own inventions, not divorced from reality. I should have brought it with me.

Some time ago, a pupil of 12 years old invented the "interlocking interchangeable protective window", which attracted many people's attention. Changsha Shahuqiao Primary School 12-year-old Zhang, who invented the "linked interchangeable protective window", won the gold medal of 1 18 Paris International Invention Exhibition, which was the highest prize won by the China delegation in this invention exhibition.

It is reported that this invention is mainly inspired by transparent elevators. It uses the principle of roller skating to open the latch of the window As the glass window rises and falls, the fence will also slowly descend at the same time, which can prevent children from falling. This humanized, practical and functional design won applause.

Many netizens have said: "Children's creativity deserves praise." "A house full of security window is like a prison. I think this idea is very good. "
