Description

Nose pad structure

The present invention relates to a nose pad structure that can be used repeatedly in a mask, helps to close the gap between the mask and the face, and can give the mask better anti-fogging performance.

The mask is worn over the nose and mouth to prevent harmful substances from entering the wearer's nose and mouth, or to prevent the wearer from spreading germs to others. Faced with increasingly serious pollution today, masks are also often used in daily life to block suspended particles and sand dust in the air. Therefore, the demand and consumption of masks are increasing. Masks have different designs for different purposes. In terms of materials, most of them are made of fiber materials such as cloth, non-woven fabrics, paper, and plastics in the form of sheets to form a three-dimensional barrier to droplets and dust. Sometimes materials such as activated carbon are added to absorb organic gases and toxic dust.

The general disposable flat mask on the market consists of a mask body and straps fixed on both sides of the mask body. The upper edge of the front side of the mask body is provided with a nose pressure strip, which is mostly made of metal. Or made of plastic objects such as harder plastic materials. When the two straps are respectively sleeved on the two ears, the mask covers the nose and mouth of the face, and is tightly attached to the face. The user can squeeze it with fingers The nose pressure strip adjusts the curvature to approximate the shape of the user's nose, helps to close the gap between the mask and the face, so as to increase the conformability of the mask and improve the safety of wearing.

However, although the nose-pressing strips of the above-mentioned masks can prevent the dirty air from infiltrating from the upper edge of the mask, in fact, the sealing effect is limited and it is often impossible to maintain close contact between the nose, cheeks and the mask. When the temperature difference between the inside of the mask and the outside of the mask is too large, the hot air exhaled by the human body will still be discharged upwards through the gap. If the mask user wears glasses at this time, the lens will easily generate fog on the lens that affects his vision or causes breathing It’s not comfortable.

Therefore, there are other types of nose pads for masks on the market, such as Republic of China Patent Publication Nos. M450391, M511344, and M286053. They all disclose a nose pad that can be stuck on the inside of the mask with adhesive or adhesive resin. The nasal bridge cushion can be disposable or reused. The nasal bridge cushion is made of plastic material and is integrally formed to be slightly wavy. In the structural design, one side of the nose bridge cushion has a flat joint surface, and the other side (E.g. the inner side) is formed with two nose pads separated by a certain distance, of which two nose pads are each in the shape of an arc that protrudes outwards. The nose bridge pad can be further provided with a metal strip that can be repeatedly bent and easily shaped; When the user wants to wear a mask, he should first stick the nasal bridge cushion to the inside of the mask and then wear it. Use the nasal bridge cushion to adjust the curvature and shape of the mask to prevent the mask from sticking to the nose and mouth, and to fill the gap between the nose and the bones. , And reduce the space of the gap to increase the air density of the nose, greatly reducing the phenomenon of exhalation rising from the gap.

However, like the above-mentioned conventional structure, the structure contains many defects in manufacturing and use: 1. If the above-mentioned nose pad is used repeatedly, the metal strip is easy to loosen after repeated use, and it will lose its function after a long time. The close effect cannot maintain the close contact between the nose, cheeks and the mask. 2. The shape of each person's nose varies from person to person, especially those with tall noses. Because of the traditional nose pads, the nose pads cannot be adjusted completely according to the shape of the nose, so that people with tall noses cannot overcome air leakage when using them.

In view of this, the present invention provides a nose pad structure that can be reused in a mask, helps close the gap between the mask and the face, and can give the mask a better anti-fogging performance, which is its main purpose.
