Description

A high-adhesion replaceable filter mask

Technical field:

The utility model relates to an improved mask for protection, in particular to a mask with replaceable filters with high adhesion.

Background technique:

People usually use masks for two purposes: first, to prevent pollutants such as impurities or germs from entering the user's respiratory tract; second, to protect other people from being attacked by germs and other pollutants exhaled by the user. A good protective mask should meet the following three conditions, one is that it can fit well with the user's face, the filtration efficiency is high, the other is that the breathing resistance is small, and the third is that the user feels comfortable.

The structure of the traditional gauze mask has poor adhesion to the human face. Many fine particles that are extremely harmful to us will enter the respiratory tract and lungs through the gap between the mask and the face. Its filter materials are generally some mechanical fabrics. The only way for this kind of filter material to achieve high dust suppression efficiency is to increase the thickness, and the negative effect of increasing the thickness is to make the user feel a lot of breathing resistance and feel uncomfortable. The electrostatically treated non-woven fabric can not only block large dust particles, but also the electrostatic charge attached to its surface can absorb fine dust through electrostatic attraction, achieving high dust blocking efficiency. The thickness of the filter material is very thin, which greatly reduces the breathing resistance of the user and makes him feel comfortable. In order to achieve the above purpose, the mask must keep close to the user's face, and the medical protective mask must provide good tightness. Due to the difference in the face shape of the user, this requires that the mask must meet the face shape of different users to ensure good adhesion and low leakage rate during use, which can prevent impurities or germ particles from entering or the user exhaled germs, etc. Exhale, otherwise the mask will lose its protective meaning. There are many kinds of masks on the market today, and each manufacturer has different styles, but according to the test of the Medical Device Quality Supervision and Inspection Center (Testing Center), not many of them meet the tightness requirements.

Invention content:

The purpose of the utility model is to provide a high-adhesive replaceable filter mask with beautiful appearance, good adhesion and replaceable filter.

In order to achieve the above object, the technical solution adopted by the utility model is:

A high-adhesion replaceable filter mask, including a mask main body, a filter and an inner support, a replaceable filter is provided inside the mask main body, and an inner support that can support the filter is provided inside the filter .

The main body of the mask is composed of three layers of sterile gauze, the middle part is wider, the two ends are narrower, and it is axisymmetric. After unfolding, a protective cavity matching the human face is formed inside. bring.

The filter piece is "C" shaped, and is made of two pieces of "C" shaped medical non-woven fabrics heat-bonded along their convex edges. After being unfolded, a protective cavity is formed inside. A circular pad is provided at the opening of the "C" shaped filter, and a hole matching the protective part of the human face is arranged at the center of the circular pad, and the hole is smaller than the opening of the "C" shaped filter. The edge of the round cloth is tightly glued to the edge of the opening of the "C"-shaped filter, so that after the "C"-shaped filter is unfolded, a larger protective cavity is formed inside. The filter is made of antibacterial and antiviral medical non-woven fabric, which has a strong function of killing bacteria and viruses. The round doilies are made of impermeable, airtight soft material.

The inner support is a "C"-shaped mesh plastic bracket with strong toughness and elasticity, and the upper part is designed as a nose clip groove, which can fit closely with the human nose. The inner support coincides with the protection cavity of the expanded "C" shaped filter, and is placed in the protection cavity of the "C" shaped filter to support the filter and padding to make the protective cavity formed inside larger , to prevent the inward compression of the filter when inhaling, the protection cavity becomes smaller, and the breathing resistance becomes larger, which makes people feel uncomfortable. At the same time, it can support the doily, so that the doily can be combined with the human face more closely.

The beneficial effects of the utility model are: the mask is elegant in appearance, has stronger tightness, can be suitable for different face shapes of men and women, and can meet the needs of different groups of people. There is an inner support in the protection chamber of the "C" shaped filter to support the filter and padding to make the protection chamber formed inside larger, preventing the protection chamber from being compressed due to the inward compression of the filter during inhalation. When it becomes smaller, the breathing resistance becomes larger, which makes people feel uncomfortable. At the same time, it can support the doily, so that the doily can be combined with the human face more closely. The filter is easy to replace, and the filter is made of antibacterial and antiviral materials, which makes the mask have a strong function of killing bacteria and viruses. The main body of the mask and the inner support can be reused after being sterilized, which reduces the cost of the mask. The main body of the external mask can block larger particles of dust and some germs, and the inner filter can further filter the air, blocking smaller particles and germs in the air outside the filter, and purifying the air after filtering step by step more thoroughly.

Detailed ways:

A high-adhesion replaceable filter mask, comprising a mask main body 1, a filter 2 and an inner support 3, a replaceable filter 2 is provided inside the mask main body 1, and a replaceable filter 2 is provided inside the filter 2. Lift the inner support 3 of the filter disc 2.

The mask main body 1 is made of three layers of sterile gauze, the middle part is wider, the two ends are narrower, and it is axisymmetric. Elastic ear straps.

The filter 2 is "C" shaped, and is made of two pieces of "C" shaped medical non-woven fabrics heat-bonded along their convex edges. After being unfolded, a protective cavity is formed inside. An adhesive body 22 for bonding with the mask main body 1 is provided on the outer surface of the "C" shaped filter sheet 2 . A circular pad 21 is provided at the opening of the "C"-shaped filter 2, and a hole matching the protective part of the human face is provided at the center of the circular pad 21, and the hole is smaller than the "C"-shaped filter 2. opening. The edge of the circular pad 21 is tightly glued to the edge of the opening of the "C"-shaped filter 2, so that after the "C"-shaped filter 2 is unfolded, a larger protective cavity is formed inside. The filter sheet 2 is made of antibacterial and antiviral medical non-woven fabric, which has a strong function of killing bacteria and viruses. Circular pad cloth 21 is made of watertight, airtight soft material.

The inner support 3 is a "C" shaped mesh plastic bracket with strong toughness and elasticity, and the upper part is designed as a nose clip groove, which can fit closely with the human nose. The inner support 3 coincides with the protective cavity of the expanded "C"-shaped filter 2, and is placed in the protective cavity of the "C"-shaped filter 2 to support the filter 2 and the padding so that the formed inside The protection chamber is larger, preventing the filter plate 2 from being compressed inwardly during inhalation, the protection chamber becomes smaller, and the breathing resistance becomes larger, which makes people feel uncomfortable. At the same time, it can support the doily, so that the doily can be combined with the human face more closely.

How to use: Take out the filter 2 and the inner support 3 before use, insert the inner support 3 through the hole above the cloth, with the end with the nose clip groove facing up, stretch the filter 2, and then pass through the bonded body 22 is bonded on the mask body, and then after the hole on the pad cloth is matched with the people's face protection part, it is fixed on the face by the high elastic ear straps at the two ends of the mask body 1. After using once, first remove the filter sheet 2 from the mask main body 1, then take out the inner support 3 from the filter sheet 2, after the mask main body 1 and the inner support 3 are sterilized, then add a new filter sheet 2 to repeat for many times times used.
