AI Technical Summary
The existing masks for health use are heavy, and there is no pressure relief at the bridge of the nose, which leads to a strong sense of compression at the bridge of the nose when worn for a long time, low comfort for wearing, and occasionally dizziness, which is not very practical.
The mask body and the outer and inner bracket made of silicone are combined with the organ-style folding pressure reducing layer and limiting device to reduce the pressure of the nose bridge and increase the wearing comfort.
Through the accordion-style wrinkle pressure reduction principle, we can effectively reduce weight, reduce the feeling of pressure, improve wear comfort and overall practicality.
