Let me explain what an anti-fog mask is first. Anti-fog mask is based on the original mask with a gas barrier layer attached to the bridge of the nose in the opposite direction to prevent gas from flowing out of the upper part of the mask and fogging the glasses.
For this pupil, I can only say that I admire him very much. It's amazing that he can find such a small detail from an interview with Academician Zhong Nanshan. I'm also surprised that he can apply for a patent. Why haven't such a simple little idea been tried? There must be something wrong with this. We all know that the structure and function of the mask are used to help resist the droplet virus in the air, so it is a great test for the airtightness and breathability of the mask. If the child is designed like this, the breathability of the mask can't be guaranteed, because the airflow can only penetrate from the front and bottom of the mask, which will speed up the life of the mask and do some harm to the human body. Wearing such a mask for a long time may cause eczema on the face, because the accumulated airflow will liquefy the face and make the mouth and nostrils moist. This is also a waste of disposable masks.
Of course, the use experience of such masks is not high, so the possibility of production is also very small. But it can also be applied to some special occasions, such as interviews and a series of occasions. You can study its use in other fields. For example, in the industrial field, this is a good product for people who wear glasses.
However, such an anti-fog mask also has its advantages, which can effectively prevent airflow from entering the glasses to liquefy. Therefore, his innovative spirit is still worthy of our appreciation. I hope he can talk about this invention, continue to study it in depth and solve some problems. As a college dog, I still admire this student. I hope he can consider the factors of human mechanics in the process of learning and inventing in the future and create more meaningful products for us.
